This invention relates tothat class of objects known as smokers’ articles and ‘in particular to smokers’ pipes. , “ Pipes of various types are known which have » been lined with, various compositions such as licorice and a solid, syrup‘ and a solid or honey and a‘ solid. It will be noted that these linings all have as a base, a liquid substance which is likely to be dried out over a period of time if the inte 10 rior of the pipes is subjected to the varying con— ditions of the air known to exist in warehouses,v stores or other places of storage or display. The linings may thus be subject to. chemical or physi cal changes. 7 ~ » 3 It is an object of this invention to protect these linings from variations of the atmosphere. It is another object of this invention to protect thelining from- the chemical or physical change or injury by providing simple packing and closure 20 means all within the bowl of the pipe. It is well known also that tobacco has been used as the solid referred to above to form the lining, while the licorice was used to bind the tobacco and sweeten the pipe. This has been 25 found unsatisfactory since the tobacco burns out of the pipe lining and'leaves a gummy mass ‘of licorice upon the walls. of the pipe. The pores. ‘of the pipe become clogged, and the pipe be 1936, ,Serial No. 72.169 . ‘7 (01. ‘131-42) “ tained in the bowl by a suitable lid or cover glued or otherwise held upon the outside of the bowl. . These‘pipes were unsatisfactory because the glue gummedthe pipe and smelled when it, became hot. Also this and other closure retaining means 5 marred the outer surface of the pipe. It is ‘an object ‘of this invention to provide a pipe vof ‘a permanent type containing tobacco. It is a further object to retain the tobacco with in the pipe by closure, means within the‘ pipe such that the beauty of the bowl is not impaired. These and other objects and advantages will appeanfrom the following description of my invention in, which I refer to the appended draw ing throughout the various ?gures of whichlike numerals refer to like parts and in which: Fig. l is a perspective View of one style of ’ pipe showing the closure means; ' , Fig. 2 is a side elevation ofathe pipe bowl partly in section; . Fig. 3' is a top plan view of the preferred form 20' of closure member; Fig. 4 is, atop View partly in: perspective of a second embodiment of the closure member, and Fig. 5 is. a section through the closure member along line5=5 of Fig. 4. , ' ; i ‘As clearly shown in the preferred embodiment of my invention depicted in Figs. 1 and 2, I have comes strong. According to this invention a ' provideda well known shape of briar pipe 2 with porous, preferably non-combustible material a lining 4. I prefer to make'this lining of. a may be used and mixed with a. honey binder. It is an object. tov provide a pipe with such a porous binder, and it is a further object to cure this lining with tobacco while the pipeis on display.v It is yet another object of this invention to.‘ pro vide economical‘ and easily removed closure means for retaining the tobacco within the pipe.‘ Another object is to provide a pipe which may be- offered for sale- ready tobe smoked. And it i is. 'a further object to provide for the smoking public a pipe lined 0r unlined and partially cured with the proper tobacco. It is not generally known among‘smokers that the ?rst pipeful of tobacco smoked in a new pipe 45 should be a pure tobacco uncontaminated with prune juice, licorice or other gummy substances. Tobacco of the preferred type is not readily ob tainable in quantities small enough for the single pipeful needed. It is an object to provide a pipe 50 packed with tobacco of the type correct for breaking in a pipe. I am aware that ?lled pipes of various kinds have been made and offered for sale. These pipes have been, so far as I am aware, of a very 55 temporary material. Also the tobacco was re plastic mass of ‘pure honey and a porous, non combustible, solid material which has'been com minuted to. the desired degree of ?neness. When this plastic» mass has been mixed in such propor tionsfas‘tosform a plastic mass which has a very. 35‘ slight ?ow coei?cient it is applied to the inner surface ofv the pipe in any manner such as by moulding about .a collapsible core. ‘The pipe may be treated‘ in any way to cause the lining to set,'such as by ‘baking. The baking process, if this be used, must, however, be‘stopped before the, honey becomes dried out to such an extent as to‘icrumble.v The invention contemplates the continued- maintenance of the'lining in that‘ de gree of moisture which is best suited to carry 45 out the purpose of the lining.' While I have hereto-fore referred to a briar pipe with a lining, it will be manifest that it is Within the spirit of my intention to embody my invention in pipes having varous shapes of 50 bowls and various combinations of materials, whether moulded or milled. It will be obvious that I may use a lining or not because the struc ture alone, as well as the discovery of the need 55 $2,111,588 2 for and the bene?cial result of the structure, is an important part of my invention. Referring to Figs. 1 and 2, the lining material is ?nished in a convex curve 6 fora space from the top of the lining. The inner surface of the lining, or the inner surface of the pipe bowl, if no lin ing be used, is then curved concavely as at 8 to form an annular groove. While it is not essential that this groove be of any particular width, that 10 is, from top toward the bottom of the pipe, it is preferable slightly wider than the thickness of well known three-ply paperboard commonly known as cardboard. The pipe bowl is next packed with an un 15 sweetened tobacco l0 possessing a degree of mois ture which may be found from experiment to be most suitable for “breaking in pipes.” A clear Havana type tobacco which is slightly crimp out has been found by me to be most suitable, since 20 this leaves the pipe in a sweet ungummed con dition. I have found also that this type of to bacco has bene?cial results as a curing tobacco since it permeates the porous material of the lin ing or the pipe bowl and impregnates these mate rials with a sweet tobacco taste. The degree of moisture which I have found most suited for retaining the pipe bowl or lining in condition may be determined by touch rather than by the use of complicated testing apparatus. The tobacco should be such that it will feel slight ly dry but will not powder when it is rolled be tween the hands. I use a slightly crimp cut tobacco which is packed in the bowl up to the lower limit of the annular groove 8. A closure member 12 is then pressed into the pipe bowl until it springs into place in the groove 8. Preferably this closure member consists of a 3 ply paper disc having a diameter slightly less than the distance from the bottom surface to the opposite bottom surface of the groove 8. Per fect ?t is not essential since the above mentioned crimp cut tobacco has the tendency to expand by uncurling. This expansion of the tobacco 45 urges the disc tightly against the upper side of the groove and insures a seal. It will be obvious, of course, that I may use oval shaped closure members for pipes with oval bowls since the invention is not limited to a particular shape of 50 bowl. Also I may, if I ?nd it desirable, treat the closure member with a moisture-proo?ng compound before the closure members are die cut from the sheet. Paraffin might, for instance, be spread upon the surfaces of the paper sheet or 55 a coating of shellac applied. Also a cellophane or other moisture-impervious material could well be used in combination with these closure mem bers. It would be economical to apply a sheet of cellophane to the sheet of paper which is to be 60 die-cut to form the closure members. The laminated fabric would then be out out in a single operation. As shown in a second embodiment of my in vention depicted inFigs. 4 and 5, I may provide the disc l2 with an integral tab for ease of re moval. The tab I4 may be formed by making a U-shaped line of cut I6 part way through the body of the disc. It will be obvious that I have discovered a simple form of closure member which is prefer ably for use in retaining a quantity of tobacco in unused pipes. It will be equally manifest that the closure member is not limited to use with new pipes. For instance. I may supply a quan 10 tity of suitable discs to be later used to retain the ashes and unused portion of the tobacco from spilling into a smoker’s pocket or on a desk or table. I am aware that others have disclosed various means for the accomplishment of this 15 same end. However, no other person has pro vided a closure member of such convenience and simplicity. Nor has anyone produced a closure member which may be so economically produced that it may be thrown away after one use and at 20 a slight cost. Metallic devices which are retained by spring arms have been used but these have many disadvantages, such, for instance, as the necessity of folding and unfolding the arms. Others have disclosed a sack-like device of rub 25 ber and asbestos which may be rolled upon the pipe. Yet other pipes have been provided with a flat base so that they may be kept in an up right position. I have found that I may use the disc described. 30 above to retain tobacco and ashes in a partly smoked pipe. The ashes which remain above the burning tobacco act as an excellent insulator, which is effective to prevent burning of the paper disc for the short time that the tobacco continues 35 to burn. The lack of oxygen in the closed pipe bowl assures prompt extinguishment of the smoldering. While I have declared that card board of a well known type and cut into the proper shape may be used for closure members in 40 burning pipes, it is Within the contemplation of my invention that I may use a non-combustible or a poorly combustible material such as asbestos paper of a desired thickness or combinations of asbestos paper and a combustible paper. I may 45 also use a wood or linen pulp paper which has been so highly compressed that it has a high re sistance to heat. While I have described the preferred embodi ments of my invention, it is to be understood that 50 I do not limit myself to the exact examples de clared, but I may make modi?cations or improve ments thereof without departing from the spirit of the invention. 55 I claim: A pipe comprising a bowl, a lining covering the inner surfaces of said bowl, an annular groove in said lining spaced from the top edge of said lin ing, a substantially ?at imperforate disc of less peripheral extent than said groove adapted to 60 have a seal in said groove, and a tobacco ?lling in said pipe exerting an upward pressure upon said disc to effect said seal.
