Filed July 19, 1962, Ser.N0. 210,928 2 Claims. (Cl. 101-131) This invention relates to a pattern reproducer of a type adapted for use in the garment industry wherein an elongated sheet carrying a master pattern is treated to transfer .the pattern impressions therefrom to an impression receiving sheet, which latter comprises -the `actual pattern material from which the material for a garment is cut. 'One of the objects of the invention is to provide means whereby the copy paper is moistened with a solvent and then brought into contact with the master pattern sheet, the moisture in the copy paper causing -at least a portion of the ink delineating the master pattern to be at least partially dissolvedand transferred Vto the copy paper, the two sheets being conveyed to 4a heater ordryer and the sheets then individually rewound upon suitable rewind mechanism.
Another object is to provide means for efliciently and effectively feeding the two sheets through the apparatus and past the heater or dryer including simple and effective drive means therefor. y
A further object of the invention is to provide improved means for supplying a liquid solvent and for distributing the solvent over the copy ,paper to meisten the same before it is brought into contact with the master pattern,
A further object is to provide an improved heating device.
Another object is to provide simple and eflicient means for unwinding and rewinding the two sheets.
Still a further object is to provide improved' means for mounting the moistening, pressure and guide rollers.
The aboveV `and. other objects will more fully appear from the following description in connection with the accompanying drawings:
FIG. l is a side elevational view of anV embodiment of the invention;
FIG. 2 is a plan view thereof on an enlarged scale;
FIG. 3 is a longitudinal sectional view on an enlarged scale taken approximately on line 3-3 of FIG. 2;
FIG. 4 is an enlarged sectional view taken approximately on line 4 4 of FIG. 3; and l FIG. 5 is an enlarged sectional view taken on approximately line 5-5 of FIG. 4.
The device includes a frame 6 having a pair of forward end uprights S and a pair of rear end uprights 10. The pairs of uprights areV joined by horizontal longitudinal frame members 12 and 14. Extending between the longitudinal or side members 12 and 14 is a bed 16 preferably of flat sheet material upon which is a feltcover 18. The bed 16 extends from the forward or left portion of the frame as viewed in FIGS. 2 and 3 to a heater lamp housing 20 having a glass top plate 22 which is in the same horizontal plane with and forms an extension of the bed plate 16. Within the housing 20 is a tube 24 of an infra-red or other suitable heat lamp energized by a source of electricity, not shown. The housing 20 and heat lamp tube 24 are shown in FIG. 2 to describe a tortuous path and provide spaced transverse heating areas which extend a substantial distance lengthwise ofthe frame 6.
Mounted between the `forward end members 8 of the frame 6 is a lower roller 26 adapted to rotatably support ati/aast Patented Feb. 23, 1965 i ce lowing the moistening roller 38 or to the right thereof, as
viewed in FIGS. 2 and 3, in a series of pressureyrollers 40, 42, 44 and 46. VThe moistening roller 38 and the pressure rollers 40-46 are placed in close proximity to the upper surface of the felt cover 18 on theupper side of the'bed plate 16.
The master pattern sheet 34 is` fed from its lroller 32 above a diagonal guide plate `48 carried -by the frame 6 so that said master pattern sheet will feed beneath the roller 4i) to the rightof or followingthe moistening roller 38, the master pattern sheetV 34 and the copy sheet 28 being brought together between saidroller 40 and the bed plate 16 with its felt coversll. The copy paper is first moistened by the moistening roller 3S and then brought into contact with the master pattern sheet 34 and pressed beneath rollers 4l) through 46 tov cause the moistened copy sheet 38 to pick up the pattern impression from the master pattern sheet, after which the two sheets are passed vover the heater or dryer 20, `after which the two sheets Y are separated and rewound. When the two sheets leave the heater or dryer 2l), they pass between guide rollers 50 and 52Vwhich preferably come together on an extension of the plane of the upper side of the dryer 20 to keep the two sheets flat on the dyer. After passing through the guide rollers Sil and 52, the master pattern sheet 34, as shown in FIG. l, passes upwardly and is rewound into a roller 54 on a rewind roller 56 mounted in notches 58 in the right frame end members 10. The copy sheet 28 passes over the guide roller 52 and thence downwardly v and is rewound on a rewind roller 6d.
Mounted beneath the sideimembers 12 and 14 of the frame 6 is a sling 62 which supports an electric motor 64. The motor shaft 66 carries a sprocket 68. Chain 70 leads from the sprocket 68 to a sprocket 72 on the pressure roller 46. This roller has a second sprocket which lies behind the sprocket 72 as viewed in FIG. l, the second sprocket not being shown, since it is beneath a chain '74 which runs over sprockets 76, 78, 80 and 82 respectively on pressure rollers 44, 42 and 4l) and the moistening roller 38. The motor 64 rotates in a counter-clockwise Va cross shaft 90 which is mounted between the right a roll comprising an elongatedsheet 28 of copy paper.
The roll 26 is removably received in suitable notches formed in the forward upright frame members 8.
Above the roller 26 is a roller 32 which carries a rolled Vsheet 34 of paper carrying the master pattern to be reproduced, said master pattern having a soluble ink or frame uprights or end members 10. The shaft carries a second sprocket 92 about which is a chain 94 driving a sprocket 96 on the upper rewind roller 56.
VAnother sprocket 98 on the shaft 90 drives a chain 100 which leads downwardly to drive a sprocket 102 on the lower rewind roller 6i). These drive connections rotate the lower rewind rollers 56 and 60 in a counterclockwise direction as shown.
Rollers 38, 4t), 42 44 and 46 and the copy sheet leading guide roller 36 are all mounted in gerenally the same manner, that is, between a channel iron 104 on each of the horizontal side frame members 12 and 14 and a superimposed angle iron 106, these two elements being separably connected by suitable bolts 108. Each of the members 104 and 106 is provided'with a complementary semi-circular aperture to accommodate the ends or hubs of the various rollers. To keep each of the rollers 36-46 in its proper axial position, each roller is provided with a collar 114, the collar shown in FlG. 4 being typical. The collar in each instance extends snr/deesa through slot 112 in the channel iron 104 and its lower portion lies in a recess 114 in the horizontal frame side member 14.
FIGS. 4 and 5 illustrate the structue of the meistening roller 38. It `includes an inner cylinder 116 having apertures 118 and lying within an outer cylinder 120 having apertures 122. The outer cylinder 12@ frictionally engages the inner cylinder 116 but may be rotated relative thereto by grasping it and turning it, the inner cylinder being held through its chain connection with the motor 64 in order to maintain the two cylinders in .their desired relative positions the inner wall of the outer cylinder 124D is provided with dimples 124 which are adapted to releasably accommodate rounded projections 126 on the outer wall of the inner cylinder 116. Also, that portion of the inner cylinder defining each of the apertures 118 is provided with a rounded projection to seat within its respective aperture 122 in the outer cylinder 126. The outer cylinder 129 can be rotated from the position shown in FIG. 5 to a position where the apertures 122 thereof receive the projections 126 of the inner cylinder 116, thereby cutting oil flow communication through theV inner cylinder and outer cylinder, but when in the position of FIG. 5, the two cylinders are held to provide free iiow from the interior of the inner cylinder to the exterior of the outer cylinder.
The right end of the moistening roller 38, as viewed in FIG. 4, is provided with a sleeve 128 which constitutes a hollow hub for said roller. The projecting end of said hub 128 is externally threaded to receive a collar 138 in which is an inwardly projecting O-ring 132.
Removably extending into the collar 130 is a spout 134 of a container 136 adapted to hold a supply of pattern ink solvent. The container spout is provided with an external annular groove 138, and when it is inserted in the collar 139, the O-ring 132 will seat in the groove 138 to removably hold the spout in the collar. A suitable bracket 140 provides a support for the cont-ainer 136 in conjunction with the detachable connection with the 0-ring 132.
Liquid flowing from the contained 136 through the hollow hub 128 to the interior of the inner cylinder 116 will dow through the apertures 118 and through the registered apertures 122 of the outer cylinder and moisten a felt covering 142 which lies about thel outer cylinder. yThis felt covering will cause the solvent to spread over the area o the outer roller and the felt covering 142 and thereby uniformly meisten the copy sheet 28 as it passes beneath the moistening roller 38.
The rst pressure roller 4t) is `spaced a sufficient distance from the moistening roller 38 to create a time interval in the travel of the copy sheet 28 of sucient duration to meisten the copy sheet 28 to the degree that it can begin to pick up ink on the master pattern sheet 34 which delineates the particular pattern piece. This pickup or transfer is further assisted by the succeeding pressure rollers 42, 44 and 46.
After leaving the pressure rollers the two sheets are carried across the heater or dryer housing 20 and lamp 24, the extend of said housing and lamp longitudinally of the frame 6 being sufficient to substantially dry the ink which denes the patterns. Having been heated, the ink or other transfer substance remaining on the master pattern sheet .34 and that which has been transferred to the copy sheet 28, will have dried by the time each of the said sheets is wound upon its respective rewind roller 56 and 60,
Inasmuch as it does not matter which end of the master pattern sheet 34 is rst introduced into the apparatus, the roll '54 of rewind master sheet material can be removed from the right end frame members 10 to the left end frame members 8 ready for reintroduction and reuse, since the ink or other transfer substance is applied to the master pattern sheet in suiiicient quantity to permit the rerunning of several copy paper sheets with the resultant multiplication of the reproduction from the single master pattern.
It will of course be understood that various changes can be made in the form, details, arrangement and proportions of the various parts without departing from the spirit of the invention.
l. In a clothing pattern reproducer, a frame comprising a front upright unit and a rear upright unit, side frame members extending longitudinally between said front and rear upright units, a ilat bed supported bebetween said side frame members at the front portion of said frame, a plurality of rollers extending betweenA and rotably supported by said side frame members, a heater assembly extending .between and supported by said side frame members rearwardly of said flat bed and having a smooth flat top surface on a horizontal plane substantially coincident with the upper surface of said at bed, said front upright unit extending above said ilat bed and having a copy sheet and a master pattern sheet feed roll' supported thereon, the rear upright unit having a copy sheet and a master pattern sheet feed roll supported thereon, said plurality of rollers extending transversely of said bed with their lower portions on a common plane and contacting said bed to produce pressure on superimposed portions of said copy sheet and master pattern sheet between said rollers and the bed, said rollers including a forwardly disposed sheet moistening roller and a following set of pressure rollers located between the front and rear of the bed, and means for driving said moistening pressure rollers and said rewind rolls.
