Tai-box, Philadelphia, Pa. Application March 1, 1934, Serial No. 713,558 18 Claims. (Cl. 131-12) My invention relates to smoking pipes and method of cleansing the same. Such pipes are commonly intended for use in connection with loose tobacco. A special class of such pipes, 5 however, has to do with cigar and cigarette'hold ers or otherutilization of tobacco in wrappings or containers. My invention may be applied to any of these. Its outstanding object is the eflicient collec 10 tion of moisture and other content of the smoke which usually collects within the stems of pipes and the eiìicient cleansing of the stem of such products. A further object is the guarding of the stem 15 with a cleansing device against the entry of solid mattei' from the pipe charge and the eiiicient ejection of the charge residue and eñìcient cleansing of the pipe bowl. The latter two re sults aid materially in guarding the draft mem bers of the pipe against entry of solid matter from the charge. A yet further object is to maintain open and free from deposit which may obstruct the draft, Figure 5 is a top plan view of the form of Fig. 4. 10 Figure 6 is an axial section of still a fourth form. Figure 7 is a general side elevation showing in dotted lines the application of the invention to pipes having curved mouthpieces and bowls at l5 acute angles to the stems, such as commonly found in curved or depending stem pipes. Figure 8 is an axial section of a pipe or ciga rette or cigar holder embodying the invention of Fig. 6. 20 Figure 9 is a portion of the section of Fig. 1 showing the parts in an ejecting position. Figure 10 is a similar view of a portion of Fig. 2. Figure l1 is a front end view of the form of the invention shown in Fig. 1 with the parts 2l broken away taken on line Il-II of Fig. 1. These objects I attain outstandingly by includ of invention shown in Fig. 4 showing the section of the front end of the plunger. Figure 13 is a transverse section through the 3` connection between the stem and mouthpiece of the form of Fig. 1. Similar reference numerals are used through out to designate similar parts. The bowl vof the valve connection is provided between the cham ber and the pipe bowl. In the bowl of the pipe Figure l2 is a section on line I2-I2 of the form pipe is designated I0, the mouthpiece in general 35 Il, the stem in general I2. Intermediate the bowl I0 and the mouthpiece II there is used above the pump there is provided in all cases a in each of the several forms of the invention a disc type guard. This guard is axially recipro cable into and out of its guarding position by displacement pump designated generally various means. 'I'he utilization of a pressure force pump for the ejection of the liquid condensate and ash or other solid content of the smoke which is col lected by condensation usually in the stem, is the means best known to me at the present time for carrying out the method of my invention which is simply this. A ñuid pressure is de veloped within the liquid content of the pipe 50 and this iiuid pressure is utilized to eject the contents themselves. The drawings represent several of the best embodiments of my invention. Referring to them- 55 stem axes. particularly the opening between the draft por tion of the pipe and the bowl but also all other parts of the draft members. ing in the draft connection between the mouth piece of the pipe and the bowl a displacement type of pump through the chamber of which the draft. connection is effected and which displace ment pump has a valved connection to atmos phere for the forcible ejection of the contents of the pump chamber to atmosphere.

Figure 3 is a section on line 3-3 of Fig. 2 5 looking in the direction of the arrows. Figure 4 is a section of yet another iorm also in the plane including both the bowl and the - Figure 1 is a longitudinal section in the plane I3 through the chamber of which I4 the draft con- 40 nection from the bowl, IU to the mouthpiece I I’ is effected. 'I'his pump may be located anywhere whatsoever and in any attitude between the bowl IIJ and the mouthpiece Il and it may be of any form of displacement pump whatsoever. In the 45 several forms disclosed, however, I have for the sake of convenience located it within and con sidered it a part of the stem I2. The pump is illustrated as a reciprocating type of plunger or piston pump utilizing a piston I5 50 reciprocated longitudinally of the chamber Il and the chamber III is of elongated cylindrical form. Sometimes this chamber is annular in form defined wholly by the circular cross sec tion of the stem as in Fig. 6 or by the cross sec- 55 ' 2 2,106,774. tion of the inserted tube 28, as in Fig. 1, and sometimes it is approximately rectangular and formed partly by the walls- of the stem or in serted tube and partly by the configuration of the plunger-as in Figs. 2, 3 and 4. The piston I5 fits snugly within the chamber so as to_ move easily therein under all conditions of operation mouthpiece, or it may be a part of the integral connection 28 or the tube 28 'may be without coveringin this region if desired. 'I In the bowl of the pipe the guard 29 is sus pendedin a. position closely adjoining the port I1 by means of an annular series of small rods or use of the pipe but yet be substantially or or wires 30 welded to it at their lower ends and welded to an operating ring 3l at their upper wholly free from leakage as may be desired. The ends. 10 piston I5 is reciprocable within the chamber by means of piston rod I6. In some cases, as in the instance of Figs. 1, 6 and 48, the piston rod The rods 30 bear upon the walls of the bowl with suflicient friction to keep the guard 28 in place when moved axially into position by grasping the ring 3|. - I 8 is of small cross section located centrally of The section of Figure 1 shows the parts in the the circular chamber in the stem, as is more position in which the pipe is smoked. Port I1 common with piston rods, and in other cases, as to the bowl III is open. Port I8 to atmosphere in Figs. 2, 3 and 4, this piston rod, designated in is closed. Port 22 at the opposite end of the these views I6', is enlarged and except for its chamber I4 is open. 'I'he smoke traverses the cut-away portion which opens up the space of length of the displacement chamber I4. The the chamber I4, is substantially of the diameter moisture and other products usually condensed 20 of the piston I5. The chamber is provided at . or otherwise deposited in the stem are collected the bowl end with the port I'I, as in Figs. 1, 2 and upon the metallic walls of the tube 2li between the 4, and with a port 44 as in Figs. 6 and 8, through port I1 and the piston I5. So deposited they which it connects with the bowl and is provided appear usually as a heavy viscous liquid very also either at the bowl end, as in Figs. 1, 2 and 4, . dark brown in color. It is convenient to call the 25 with the port I8, or at the mouthpiece end, as in liquid a liquid condensate. The other products Figs. 6 and 8, with the port 45, which communi are usually ash or perhaps small particles of un cates with the atmosphere, one end at least of the burned tobacco. At any time it is desired to chamber is provided with an abutment I9 some cleanse the stem of its collected contents, the times (see Figs. l, 6, 8 and 9) constituting the smoker gives the mouthpiece and connected tube 30 solid end closure or head of the chamber and 20 a turn of 180° which results in closing the sometimes, (see Figs. 2, 3, 4 and 10-) in the form port I1 and opening the port I8'as shown in of a deñectable head or end closure I9’ serving as a scraper with which abutment the piston plunger I5 may coact to forcibly eject the con Fig. 9. Thereupon he quickly draws the piston tents of the chamber I4 through the ports I8 or liquid condensate is placed under pressure and ' 45 to atmosphere. In the forms of the invention shown in Figs. 1, 2, 3, 9 and 10 the cylinder of the pump which constitutes the walls of the chamber I4 is in the 40 form of a tube 2li with a diameter somewhat smaller than the over-all diameter of the stem I2 and which is rotatably and slidably journaled I5 the length of the chamber and into contact with the head I9 of chamber I4 whereupon the forcibly ejected from the port I8. This relation of the parts is shown also in Fig. 9. The initial movement of the piston I5 from the position of Fig. 1 closes the port 22 communicating with the mouthpiece II so that the only possible egress for the contents of the chamber I4 is axially of its length and forcibly through the port I8. But one movement of the plunger completely and thoroughly cleanses the entire chamber. In all the formsl of the invention, the close approach 4.3 through the bottom of the bowl to its egress on and ultimate contact of the` piston I5 with'either the side of the bowl opposite the stem. In the the fixed head I9 or the yieldable combined head forms of Figs. 4, 6 and 8 the cylinder constitut- ‘ and scraper> I9’ develops within the fluid com ing the walls of the chamber I4 constitutes the prised by the liquid condensate in and of itself >in a stem aperture 2| extending axially through that portion of the stem I2 connected with the bowl I8 and continuing axially of the stem stem per se in its entirety. Referring now particularly to each of the sev eral forms of the invention in succession, in the form of Fig. 1, the plunger I5 is of the piston type and normally lies at the mouthpiece end of a pipe. Here the piston I5 is bridged normally by a» draft connection 22. between the chamber I4 and the stem II. This draft connection is in the form of a slot cut in the end oi the tube 28 at its top. It establishes draft connection around 60 the piston I5 between the chamber I4 and the draft opening 23 of the mouthpiece. 'I‘he piston rod I6 is extended out through the head I9 clos ing the opposite end of the chamber I4 and provided with a small suspended ring 24 for manual reciprocation of the piston I5. The mouthpiece II is threaded on to the adjoining end of the tube 20 to such an extent that it en tirely closes the slot 22. A small screw or rivet 25 insures proper angular relation of the mouth 70 piece to the tube 28. The abutment of shoulder 26 against the end 21 of the tube may serve a similar and perhaps cooperative purpose. The outer walls of the stem may be constituted of tubular filler members as 21’ between the root 75 of the stem 28 integral with the bowl I0 and the a strong fluid pressure, and it is through this ,pressure and, in the form shown in Figs. 2 and 4, additionally through the sudden outward thrust of the movable abutment I9' by the in cline on the piston, that the forcible ejection is achieved. Immediately the plunger may be re- . turned to the normal position of Fig. l and the mouthpiece II and attached tube 20 turned back through 180° closing port I8 and again opening the port I1 to the bowl. The cleaned pipe is again ready for smoking. During this smoking the guard disc 29 ef fectually guards port I'I against the entrance of solid matter. Such small grain solid matter as may once in a great while pass the disc screen 29 is eifectually cut off and cut through by the edges of the tube wall 28 at the port I1 when the tube 28 is rotated to open port I8. The turning of the edges at port I1 to the opening of the port I8 presents any such small solid matter at a point where the forcible ejection of the contents of the chamber I4 when plunger I5 brings up against the head I9 causes a‘so the forcible ejection of such occasional solid matter. However, during the great part of the time the disc 29 precludes the solid matter from reaching 3 2,108,774 This is aided very greatly by the 180° recess in the bottom of the bowl as is shown functioning of the disc 29 when it is moved axially of the bowl in ejeoting residues of in Fig. 12 whereas in the form of Figs. 1 and 2 the arrangement is the reverse with the stop 33 on the charges thoroughly and in scraping by the edges bowl and the 180° recess in the tu‘oe 20 as is shown in Fig. 11. In the form of Fig. 4 the outer wall of the stem I2 corresponds to the tube 2D of Figs. 1 and 2 and may be an integral continuation ci the bowl Ill as stated. Therefore, the valved action the port. or’ the disc 29 residue from the bowl I0. This keeps the bowl so thoroughly cleansed of minor particles of tobaccol and ash and particularly burned tobacco that such material does not ac cumulate at the bottom and therefore is not present to pass by the disc 29. Yet further, be cause the disc is used the residue of charges is ejected as a body and there is no call for the use brought about by a relative movement oi“ the parts of the stem> I2 consists in the rotation of the plunger IG’ itself instead of a rota'ion of the tube 2U Within the stem at large. Otherwise the opera tion of the form of Fig. 4 is precisely the same as that of the form of Fig. 10. The bowl of this form of Fig. 4 is also diñerent from the bowl of the form of Figs. l and 2. It is a actually project residue into the port I'I. Fur ther yet. in the packing of the pipe, particles of metallic bowl instead of a wooden bowl, preferably the new charge might enter the port I1 were it of cast duralumin. It consists of a relatively thin main shell 34 provided with radial axially ex not for the guard 29. In the form of Figs. 3 and 4 the guard is essen- ' tended external ribs 35 for cooling purposes. tially the same as in Figs. 1 and 2. It is to be noted Outside of these ribs there is superimposed a cy in Fig. 5 where the plan view is shown the draft lindrical shell 36 of insuiating material. Guard and ejecting disc 29 is connected by the wires 39 apertures of the guard 29 are in the form of with and operated by bodily axial withdrawal and notches 32 in its edge and not in the form of per replacement of this shell 36 from the ribs of the '. I... ¿i forations in its body. This results in confining the draft from the bowl to the edges of the disc bowl. The shell thus jointly serves as a manipu guard 29. This gives a better distribution of the lator of the guard 29 and an insulator of the metal of the pipe. The tubular stem I 2 may or may not draft in the bowl and affords a better burning ad joining the walls of the bowl, especially as the be formed integrally as shown with the bowl. The bottom parts of the charge are being burned. port 22' then consists of a groove formed inter- i Yet further, the notches in the edge are easily nally of the tubular stem I2 and the mouthpiece I I is threaded internally of the outer end of the stem cleaned whereas perforations in the body are dii-li cultly cleaned. More to the point, however, the instead of externally as in the other forms. The form of Fig. 6 consists of quite a different ` elimination of perforations from the mid-por tions of the guard prevents solid matter from arrangement of parts. In this the axis of the bowl dropping into and clogging port I‘I of the chamber and the axis of the stem I2 instead of being at I4 of the displacement pump. Any other means an angle to each other are in longitudinal contin whatsoever for operating the guard 29 may be uation. The 'bowl and stem are connected to gether for relative axial movement through a used. of knife blades and the like which not only sepa« rate the residue into small portions which may fall within the port I1 but also when used may l() The displacement pump of Figs. 2, 3 and 4 is of a different form. The piston I5 and the plunger IB’ are of a diameter completely ñlling and fitting the tube 20, see Figs. 2 and 3, or the bore of the complemental taper 3l between the bottom of the stem per se, see Fig. 4. The chamber I4 is formed dotted line position shown. When seated on the bowl and the adjoining end of the stem so that the bowl may be moved axially toward the mouth piece from the full line position shown to the by a longitudinal milling out of the main body of taper 31 the bowl IU makes a draft-tight joint the plunger IB' between its ends and all the way with the same. When the-bowl and stem are from the port 22 of Fig. 2 formed in the tube 20, ` moved relatively to place the bowl in the dotted or the port 22’ oi Fig. 4 formed in the stem per se line position Vshown in Fig. 6, the stem is consti to the port I‘I. The head I9' is in the form of a spring the one end of which is riveted or other wise iixed to the tube 20 (Fig. 2) or to the bottom of the bowl (Fig. 4) and the other end of which tuted an ejector for the residue contents of the bowl. To this end the disc guard 29 is mounted directly on the end of the stem and secured there to by small screws 38 or equivalent means. In projects yieldably into and closely fits the rectan lgeneral plan form the disc guard 29 is of peri gular cross section of the chamber I4 as shown in I metric outline shown in Fig. 5 and has a similar relation to the interior walls of the bowl I0. The bowl II) is provided with an upturned lip 39 ex tending the lower edge of the mouth 4D beyond ythe upper edge whereby ash may not be readily dropped from the open end of the bowl during the Figs. 2 and 3. In the form of Figs. 2 and 3. therefore, when the mouthpiece I I and connected tube 2|) are turned to close port I'I and open port I9. and thereafter the plunger I6' is pulled out as shown in Fig. 10, the head of the chamber constituted by the spring I9' not only serves as a compression head but scrapes the entire chamber I4 clear of its contents and iinally rides up on to the opposite end of the rod, which constitutes the piston I5, forcibly ejecting the contents through the port I8. The operation otherwise is essentially the same as that in Fig. 1. In this form oí the device like that of Figs. l and 4 the rotation through 180° to close port I'I and open port I8 and vice versa is TI) regulated by a stop 33 which is fixed to the wall of the bowl I0 and projects into a 180° recess in the end of the tube 20 or the end of the plunger I6' as the case may be. See Figs. 11 and 12. In the form of Fig. 4 the stop projection 33' is on the end of the plunger Ii' and extends into a smoking. The displacement pump I3 and its chamber I4 are located in the stem as in the other forms. The piston I5, however, normally lies not at the mouthpiece end of the stem but at the bowl end of the same. It is normally seated in an up (i5 ward offset 4I of the guard disc 29’. The adjoin ing end of the stem is provided with ribs 42 which guide it into and out of the chamber I4. The plunger or piston rod I6 extends toward and through the head I9 which closes the mouth- > piece end of the stem and is connected with the , mouthpiece by a screw 43 or equivalent device such as a pin or a rivet in such manner that when the mouthpiece is grasped and pulled oiï of the stem I2, the plunger is moved the length of the 4 2, 106,774 chamber I4 up against the head I9. Through radialgrooves-or apertures 44 at the bowl end of the stem free draft connection is normally main tained with the bowl I 0. This connection is valve closed by the plunger I5 in its initial movement axially outwardly into the chamber I4. Through the port 45 in the walls of the chamber I4 im mediately adjoining the head I9 the valve con nection to atmosphere is established at the loA mouthpiece end. ' 'I'his valve connection is nor mally closed by the skirted extension 46 from the mouthpiece` II. This connection may be cylin drical or taper seated as indicated at 4'I and con stitutes the seating or socketing of the mouthpiece II upon the stem I2. It extends sufficiently to ward the bowl from the port 45 to effectually seal the stem adapted to be reciprocated therein, and means establishing two valved connections, one between the bowl and the stem and another be tween the stem and the atmosphere independent of the mouthpiece, whereby the bore of the stem may be shut off from the bowl and the reciproca -tion of the piston may eject directly from the stem to the atmosphere the contents of the stem. 2.1A pipe comprising a bowl. a stem having a fixed head at one end, a piston in the stem 10 adapted to be reciprocated therein to and from the head, and means establishing a valved con nection between the headed end of the stem and the atmosphere independent of the bowl whereby reciprocation of the piston when the valved con nection is an open one forcibly ejects the con the port 45 from atmosphere when the mouthpiece - tents of the stem to atmosphere through co-ac I I is seated upon the stem.

A pipe comprising a bowl, a stem having a however, when the mouthpiece II is seated, af fords draft connection through the port 45 to the mouthpiece as shown. Draft is normally there fore maintained from the bowl to the mouthpiece but when the mouthpiece is withdrawn to pull the plunger I5 into forcible contact with the head I9, the port 45 is opened to atmosphere and the contents of chamber I4 forcibly ejected there from. This form of the invention has particular adaptation to pipes having curved mouthpieces as shown in Fig. '7. . It also has particular adaptation to pipes of the nature of cigarette, cigar or other package type holders as shown in Fig. 8 where corre Li sponding parts are provided with reference nu merals -corresponding to the numerals in Fig. 6. This form of Fig. 8 differs particularly from the preceding forms in that the bowl I0 is so small that it accommodates but one end of the pack aged charge, e. g., a cigarette, cigar or tobacco in wrappers or containers. Otherwise the gen eral arrangement of the parts is the same and their functionings are the same. The ejector ejects the residue of the charge when the bcwl and stem are relatively moved to the dotted line position. The pump I3 ejects the contents of of the stem when the mouthpiece and the body of the stem are relatively moved in the same manner as in the form of Fig. 6. In this embodi ment I have substituted for the taper seating 31 draft chamber provided with a fixed abutment at 20 one end, a piston in the stem adapted to be re ciprocated therein toward and from said abut ment, and relatively movable parts including said stem controlling a valve port from the stem to the atmosphere substantially at the abutment and independent of the bowl, whereby reciproca tion of the piston may forcibly eject the contents of the stem through the port to atmosphere through co-action with said abutment. 4.
