Leef, Minneapolis, Minn., assignor to Leef Bros., Inc., Minneapolis, Minn., a corpora tion of Minnesota Application May.8, 1937, Serial No. 141,465 4 Claims. (C1. 223-73) My present invention relates to improvements in ironing machines of the type employed for ironing the tubular portions of garments such as legs and sleeves and, in the particular form 5 herein illustrated and described, is particularly adapted for the ironing of garment sleeves. Otherwise stated, the invention relates to im provements in ironing devices of the type dis closed in prior Patents Nos. 1,937,656 and 2,022, 210, the former of which was issued jointly to myself and George H. Leef on December 5, 1933 under the title of “Garment leg ironer,” and the letter of which was issued jointly to myself and George H. Leef on November 26, 1935 under the title of “Garment sleeve ironer.” Among the important objects of the invention is the provision of a machine of the kind described that can be more quickly and easily manipulated than similar machines of this character. The 90> above and several other important objects of the invention will be made apparent in the following speciñcation and claims. In the accompanying drawings like characters indicate like parts throughout the several views. Referring to the drawings: 25 Fig. 1 is a transverse vertical sectional view with some parts shown in full and some parts broken away, taken on the line I-I of Fig. 2, looking from the right toward the left; 30 Fig. 2 is a vertical sectional view with some parts shown in full, taken on the line 2_2 of Fig. 1 and looking from the left toward the right in respect to Fig. 1; ` Fig. 3 is a fragmentary sectional view similar to Fig. 1 but being taken on the line 3-3 of Fig. 2 ating relatively movable boots Ill are connected `to and supported from their respective co-oper 10 ating fixed boots 9 by links I2, which links are pivotally connected at their lower ends to the base portions of the ñxed boots at I3 and to the upper intermediate portions of the movable boots II) by pivot hinge pins I4. The `co-operating boots 9 and I Il thus mounted, one with respect to the other, will automatically adapt themselves to rel~ ative positions necessary to accommodate different sizes and shapes of garment sleeves; and since it is desired to permit the boots 9 and I8 to be brought'into face-to-face Contact when neces sary, the opposed inner faces of the boots 9 and I0 are preferably provided with recesses I5 and I6 for reception of the connecting links I2. Under the action of gravity the movable boots I0 will normally tend to move away from their respective co-operating boots 9 on the arc of a circle struck from the points of pivotal connection between the links I2 and ñXed boots 9, and the tendency will be for the movable boots I0 to 30 move on this movable arc until the lower ends of the boots I0 come to rest upon the table top 1. However, in practice the resilient steam connec tions to the movable boots, which will hereinafter be described in detail, usually exert suiñcient re-l 35 and looking from the left toward the right with sistance to suchl extreme movement as is neces respect to Fig. 2; - sary to keep the movable boots normally posi» tioned substantially as illustrated in Figs. l, 2 and 3, wherein said boots I0 are positioned slightly above the table top. Nevertheless, it will be obvious that in the absence of sufficient resist# Fig. 4 is an enlarged detailview with some partsI broken away and some parts shown in section; 40 of boots consists of a fixed or rigidly mounted boot 9 and a co-operating relatively movable boot I0. The boots 9 and I0 are in the nature of elongated hollow shells` preferably cast of iron or other suitable metal of high conductivity. The 5 rigidly mounted or fixed boots 9 are securely anchored to the table top or supporting base 'I by suitable bolts or the like II, and the co-oper and . Fig. 5 is a composite illustrating the inlet and outlet connections to the steam chambers of the several boots, and the series hook-up of the sev eral thereof is indicated by direction arrows, the 45 several parts of this view being enclosed in broken lines. ' ' ' ance to gravitation set up by the steam connec tions the movable boots Iii, when released, will normally come to rest against the top of the table. The boots I0 are concave from top to bottom at their front faces, indicated by Il, and Mounted on a common supporting table 6, which consists of a top 'I and a frame-like leg these concave portions I'I are spanned by resilient structure 8, are two pairs of co-operating pressing boots, one of which pairs of boots is indicated as an entirety by A, and the other of which pairs of boots is indicated as an entirety by B. Each pair of boots is` identical in character and is rods I8 are loosely seated in suitable sockets I9 formed in the base portions of the boots IIl, andl 50 the upper ends of the resilient forming rods I8 are turned inwardly at 20 and work slidably in grooves or notches 2I in the upper end portions mounted in laterally spaced parallel relation on Each pair of their respective'boots ID. The inturned end portions of the forming rods I8 are retained 55 55 the‘ table top or supporting base 'I. forming rods I8, the lower ends of which forming 2. 2,128,003 against upward movements out of the notches 2| by retaining pins or the like 22. By reference particularly to Fig. 4 it will be seen that the the opposite pairs of pressing boots A and B are spaced so that both sleeves of a shirt may intermediate portions of the inturned upper ends be pressed in a single operation. I-Iitherto in machines of this character the 20 of the forming rods !8 are vertically offset at 23, and the notches 2| areV similarly offset to boots have been drawn together to an extent nec essary to accommodate a sleeve by the contract provide stop shoulders 24 which co-operate with the opposite portions 23 of the forming rods-to ing action produced under first application of the sleeve. This practice, however, is objectionable, limit outward movements of the forming rods i8 Interposed over the extreme inner ends of the forming rods |8 and extending between the opposite portions 23 firstly, in that it retards the operationl‘of insert ing the sleeve, and secondly; in that it is apt to place undue and sometimes damaging strain upon the sleeve. It is therefore an object of this in vention to provide a unique mechanism for forc ing the boots together and into minimum diam eter condition during the sleeve application and 15 removal operations. In the preferred embodi 10 with respect to the boots i9. thereof and the rear wall of the notches 2| are compression springs 25 which normally keep the ends of the pressing rods i3 pressed outward to the maximum extent permitted by the stop shoul ders 24, but which springs 25 will yield readily under contracting pressure exerted by a garment sleeve and will permit the upper ends of the forming rods i8 to be drawn up tight against the faces of their respective boots il! or to any inter mediate positions. ment of the invention herein illustrated this re tracting mechanism is foot-operated and com prises an intermediately pivoted operating lever 26 and a forked push rod 2l, opposite upper ends » 2B of which engage the bottom portions of oppo site boots l0. These forked upper ends 28 of The sleeves of the shirts of various different push rod 21 work freely through guide apertures grades and makes vary greatly in shape. Some, 25 namely, the lower quality work shirts, taper straight down from the shoulder to the cuff diam eter at the cuffs; whereas, sleeves of higher qual ity shirts such as dress shirts, usually have much less taper and at their points of attachment to the cuffs are of considerably larger diameter than the cuffs themselves. Still other shirts have sleeves which are substantially of uniform diam 29 provided therefor in the table top 1, see par ticularly Fig. 1. The lower end of push rod 21 is pivotally anchored to the inwardly projecting end of the lever 26 at 30. The intermediate por eter throughout; and still other shirts are found pedal plate 33 which is conveniently positioned to be provided with sleeves which are concave adjacent the seam. It will be obvious that it for manipulation by one of the operators. Under foot pressure applied by the operator to would be practically impossible to select any shape pressing boots which would be capable of conforming to the shape of all the different sizes and styles of short sleeves encountered in gen 40 eral laundry practice, but such difficulty is largely done away with in the preferred embodiment of this invention herein illustrated and described by the combined automatic shifting actions of mov able boots Ill with respect to their co-operating 45 boots 9 and the yielding action of the forming rods I8. In this connection it Will, of course, be under stood that when a sleeve is pulled over a pair of co-operating boots S and I9, shoulder end first and seam adjacent the forming rods I8, the mov able boots IU, after being shifted toward their co-operating fixed boots 9 to permit free appli cation of the sleeve, will move outwardly under the action of gravity until they tightly engage the sleeve and maintain the same under expanding pressure against the surfaces of the boots, and the upper ends of the forming rods will compress their co-operating springs 25 and recede into the tion of the lever 26 is pívoted on a cross rod 3| that extends at opposite sides of the frame-like structure 8 and is held axially centered on said 30 rod 3| by opposed spacing tubes 32. Preferably the lever 26 is provided at its outer end with a to the pedal-equipped end of the lever 2E, lifting pressure will be applied to the movable boots l0 through the forked push rod 21, and under this upward lifting pressure the movable boots I0 will tend to move upwardly and toward their 40 respective co-operating fixed boots 9 on the arcs of circles struck from the pivot points I3 until the upper ends of the co-operating boots come into engagement, at which time application of the sleeve will be very quickly accomplished. After the sleeve has been applied and the foot pressure released, the parts will then assume positions necessary for complete smoothing out of all the sleeve surface. Since the upper ends 28 of the push> rod engage the base portions of the movable boots lil onlyl with frictional surface engagement, movements of the lower ends of the boots l0 will be permitted even when lifting pressure is applied to the boots and lever 26 of the push rod. Ui Ui The steam chambers’within the hollow shell like boots 9 and ID of boot pairs A and B are supplied with suitable heating medium, which heads of the boots H3 as far as is necessary to ac will usually be live steam in the manner pres commodate sleeves of any particular cuff dimen ently to be described. These steam chambers 60 of the several boots are each provided with con centric steam inlet and outlet ducts, and the sion; and the intermediate and lower portions of the forming rods i8 will shape themselves to conform to the shape of the seam edge of any seam shape. The net result of the above is the F uniform stretching or shaping of substantially any sleeve shape all the way from cuff to shoul der without leaving any ruffled or loose portions, so that the finished product is substantially free from imperfections usually considered as a nec essary result of machine work. Preferably the rear sides of the ñxed 1boots S, which engage the sleeve diametrically opposite the seam edge thereof, are straight or substan steam chambers of the several boots are con nected in series. For this purpose each of the tially so from top to bottom, but, of course, this at its lower end with a conventional T-coupling 34. The outlet pipe sections |0a and Iûb of the form may be varied. In the machine illustrated several boots 9 and I0 has projecting downwardly from the screw threaded into its bottom portion a pipe-like section. For the purpose of identiñ cation the said outlet pipe sections for boots 9 and I0 of boot pair A are respectively indicated by 9a` and lila and said pipe outlet sections for boots 9 and I0 of boot pair B are respectively in dicated by 9b and lûb‘. Each of the several out let pipe sections 9a, |0a, 9h and |0b is provided .2,128,003 movable boots I0 work through slots 35 provided in the table top 1, so that the said pipe sections Willnot interfere with free oscillatory movements of the movable boots. Steam> is introduced through the serially con nected series of boots through a primary inlet pipe 36 which is screw threaded into the lower vertical opening of the T-coupling 34 that is car ried by the outlet or discharge pipe 9a of fixed boot 9 of pair A. Projecting concentrically from the upper end of the primary inlet con-duit 36 and through the associated coupling 34 and out let duct 9a and into the upper portion of the steam chamber of boot 9 of pair A is a relatively 15 small diameter conduit 31 in the nature of a drawn copper tubing. This conduit 31 is secured in the end of the conduit 36 by a conventional _ compression type fitting 38 which tightly seals the space between the small diameter conduit 31 20 and the larger internal diameter of the primary inlet pipe 36. Steam delivered through the pri mary inlet pipe 36 passes upwardly through the small diameter conduit 31 to the upper extremity of boot 9 of pair A and then passes downwardly through the steam chamber of said boot around 25 the outside of said conduit 31 and discharges from the boot 9 of pair A through outlet conduit 9a into the intermediate portion of the asso ciated T-coupling 34. The horizontal opening 30 of this last noted T-coupling 34 is connected through the medium of a compression type ñtting 39 to a small diameter conduit 40, which ex tends through the bottom of coupling 34 of con duit 10a through the center of conduit Iûa and 35 to the upper extremity of the steam chamber of boot pair A. This pipe coupling 40 is secured in the coupling 34 of conduit 10a by a compression type fitting 4l. By means of this connection steam discharged from the boot 9 of pair A is delivered to the boot I0 of pair A, and steam 40 discharged from boot ID of pair A through cou pling lila is delivered to the upper extremity of boot I9 of pair B by a small diameter tubing or conduit 42, which tubing is made fast in T-cou pling 34 in conduit loa by a compression fitting 45 43 and is made fast in the T-coupling 34 of con duit lllb by a compression ñtting 44. Steam delivered into the boot IBI)` through the conduit 42 will be discharged through the conduit Illb into the associated coupling 34, from where it 50 will be delivered through a small conduit 45 to the upper extreme portion of the steam cham ber of boot 9 of pair B. Conduit 45 is made fast in the associated couplings 34 by compression fittings 46 and 41. Steam thus delivered into the 55 steam chamber of boot 9 of pair B will be dis charged through pipe 9b~ into the associated coupling 34 and from thence will be discharged through a suitable ñnal outlet pipe 48. As previously indicated, the conduits 40, 4Z 60 and 45 are preferably of drawn copper tubing which is quite ñexible, and in order to increase to a maximum the flexing action of the portions of these conduits which connect to either of the movable boots I0, these portions of the conduits 65 40, 42 and 45 are coiled, as indicated in Figs. 1, 2 and 3. Interposed in the ñnal outlet pipe 48 is a steam-control valve 49. In the preferred embodiment of the invention illustrated the table top 1 is provided with a 70 pair of stop lugs 50, one thereof being located back of the base portion of each of the boots I D and so positioned as to be engaged by the lower portions of the boots l0 under maximum 3 desired outward oscillating movements thereof and to prevent excessive outward oscillation of the lower portions of said boots. With the structure above described, it is evi dent that while the movable boots will be simul taneously lifted and caused to approach the co operating fixed boots, under the action of the lifting device afforded by the push rod 21--28, nevertheless, that the independent supporting links i2 and the loose or slip connection between the rod prongs` 28 and the bottoms of the mov able boots I0 permit the latter, when manually pressed by the application of a garment leg, sleeve, or the like, to approach the co-operating fixed boots and thus adapt themselves to legs or sleeve structures that differ in cross-section and taper. What I claim is: l. In a device of the kind described, the com bination with a table-like supporting structure, of a pair of co-operating upright pressing boots, one of which boots is relatively fixed to said sup porting structure and the other of which boots is movable toward and from the fixed boot, a link connected at its lower end to the base portion of 25 said fixed boot and at its upper end to an upper portion of said movable boot and supporting the latter for rocking movements and for movements toward and from said fixed boot, and a lifting device movable vertically through said support 30 ing structure and having sliding or slipping en gagement with the lower end of said movable boot. 2. In a device of the kind described, the com bination with a table-like supporting structure, 35 of two pairs of co-operating upright pressing boots, each pair including one boot fixed to said supporting structure and one boot movable to ward~ and from the ñxed boot, independently movable links connected at their lower ends to 40 the base portions of the fixed boots and at their upper ends to upper portions of the co-'operating movable boots and supporting the latter for in dependent rocking movements and for independ ent bodily movements toward and from the co operating flxed boots, and a lifting device mov 45 able vertically through said supporting struc ture and having independent sliding or slipping engagement with the lower ends of the respec tive movable boots. 5.0 3. In a device of the kind described, the com bination with a table-like supporting structure, of two pairs of co-operating upright presser boots, each pair including one boot fixed to said supporting structure and one boot movable to 55 ward and from the ñxed boot, independently movable connections supporting said movable boots for independent rocking movements and for independent bodily movements toward and from the co-operating ñxed boots, and a com 60 mon lifting device mounted on said supporting structure and having simultaneous lifting move ments on said movable boots but permitting said movable boots to be independently moved toward the co-operating ñxed boots under force applied 65 thereto by means other than said common lifting device. 4. The structure defined in claim 2 in which said independent supporting links are so dis posed that the movable boots will tend to move 70 away from the co-operating fixed boots under the action of gravity.
