Be it known that I, Mosrs IsAAos, a cit-izen of the Unit-ed States, and a resident of the city of New York, borough of Manhattan, in the co-unty and State of New York, have invented a new and Improved Cloth- Laying Machine, o-f which the following is a full, clear,` and exact description.

My 'invention is a' cloth laying machine and is designed totake cloth, such as woolen cloth that is folded in half,lengthwise, and lay it upon a table in an-even pile of layers, for the purpose 'of cutting it into pieces, to make 'parts of clothing. The machine ,is made to t-ake pieces of such cloth which are either in a roll or in folds.

Reference is'to be had t0 the accompanying drawings fo-rming a .part of this specification, in which the same characters of reference indicate the same parts in all the views. v

On the drawings, lgis asten@ 0.1' table;

` Application mea March 1a, 1912. serial No. 683,514. f

along one-(if the longitudinal edges .ofwhich i 1s placed a rail 2. This rail has a pro'ecting rim or edge 3 on its'upper side, an j fixed -to the side of the table that the top of this rim will be flush Vwith the table top, but will be separated from the edge of the table by means of a groove 4.

5 is a truck forming a part ofmy cloth laying machine, this truck havin a pair of flanged wheels 6 on one side, whic run upon the rim 3 yon the rail 2, and-.a pairof fiat wheels 7 onthe opposite side, which move upc-n the smooth surface of the table. Adjacent one end of this truck is arranged a rack 8, which serves to support a bolt or roll of cloth and to let out the same when the cloth is to be laid. This rack is pivoted on 'a central bolt 8', 'and lcarries a pivoted 'shelf 11, which is attached to sup orts 9,

which are secured to the ends of t e shelf 11 adjacent one of the longitudinal edges thereof. Braces 10 are joined at lone end to the supports 9, and at the other end to the is sov shelf 11, adjacent the opposite longitudinal f edge, to strengthen the same and enable the shelf 11 to bear the weight ofthe roll of cloth, shown at 13. The end supports -9 @are both pivoted atl their lower ends to the cloth rack 8, and have projections .fromv their inner faces to be engaged by hooks 9', carried by thesides of the rack, in order that the shelf may be held in upright position.

The rack 8 carries a transverse roller 14v at the top thereof, overwhich the cloth passes, and this roller has at one. end a pinion 15 engaged by a gear 16 having'. thereon a handle 17. This handle is turned by hand when the car'is moved over the surface of the table to rotate the roller 14 andpay out the cloth.

18 and v19 are rollers carried by the rack v8, these rollers being arranged transversely wit-h respect to the truck 5, andthe cloth when itis being paid out passes over the same.

' The .bolt or roll of cloth lis partly unwound, and then laidA upon the shelf 11 in such position that the loose .end will lie at the bottom of the roll, restin'gdirect-ly upon 'the shelf 11 and extending to the left. This loose end is carried up around the roller 14, then down again under the roll 13,v and then up a second time over the roller 14. It is then passed over the roller 18 and under the roller 19, and out over the end of the truck 5. When the truck 5 moves to the left, the crank 17 is rotated by hand. Thiscauses the roller 14 to revolve, paying out the roll 13. The moment the roll 13 begins to move, the roll 13 will begin to revolve around its longitudinal a'Xis. If the hooks 9 be now released, the roll 13 as it rotates will -knock over the shelf 9, causing it to fall into the position shown on Fig. 2. The roll of cloth will then be supported in suspended position and will turn freely as the cloth is paid out, owing to the continued rotation of the roller 14. j

At the opposite end of the truck 5 is arranged a plate 20, t-his plate 20 being of some smooth material andeXtending trans- Versely of the truck across the terminal edge. Above the plate 20 is a tension de-` vice which consists of a'bar 21, carrying on its lower surface a facing of suit-able clo-th, indicated by the numeral 22, side strips 22 being employed to engage the-edges of this facing of cloth and hold it in position. The cloth normally passes over the plate 20 and beneath the cloth facing 22 of the tensioning device, as lshown on Figs. 1, 2, 3 and 10.

At the ends of the tensioning device 21, and adjacent the forward corners thereof, are arranged two pairs of guide blocks 23, each pair of these guide blocks 23 receiving a sliding shoe 24, these sliding shoes being two in inumber and having pivot pins 25 projecting therefrom, and the ends of these `pms beingreceived by apertures in plates 2,6, carried by the ends of the tensioning device 21. The lower ends of these shoes 24 each have longitudinal slots 27; and 28 are fastening yscrews passing through the slots 27 in the slidin shoes 24, and engaging the blocks 23 to ho d the shoes 24 in adjusted position. By means of this construction the forward edge of the tension device 21 can be raised slightly, as shown on Fig. 10, causing it to engageJ the cloth adjacent the rear edge. of the cloth facing 22. By lowering 4the tensioning device 21 some in front, a

larger width of the cloth facing ,22 will come in contact with the cloth, and the result will be that the u pper half of the layer of cloth will be stretched as it passes.

5 are extensions which project longitudinally from the sides of the truck 5 beyond the end whereon is mounted the tension device 21; .and 29 and 30 are transverse guide bars mountedl in the extensions 5 at their opposite ends. The bar 30 forms part of a rectangular frame 31, which consists of side members 32 joinedat their upper ends to a length of transverse tubing 30', which is mounted upon the bar 30. Two transverse bars 33 connect the side members 32 of the frame 31 together at the lower part of this frame, and 34 is a quadrant carried by one of the extensions 5 by means of which the frame 31 can be raised or lowered and held in such raised or lowered position, as desired. This quadrant 34 has a curved slot therein which receives a binding nut 35, suitably carried by one of the flat arms 32 of the frame 31, to hold the frame 31 in adjusted position, above the pile of cloth being laid'.

36 are bolts having wing-nuts on their outer ends, one of' these bolts being carriedl in the lower end of each of the side arms 32 of the frame 31.

width of the cloth, as shown on Fig. 3, and

on the under side of this guide 38 project a series of points 42. These points fit in corresponding holes in a board or plate 40, this board or plate 40 being attached to the under side of the bar 38 by means of springs, shown at 45. This board 40 is slotted to correspond to the slot 39, and the springs 45 hold the board 40 a certain distance away from the under side of the bar 38. Beneath the board 40 and carried at its ends by the side arms 32 of the frame 31, is a third transverse bar 41, this bar having a slot or ,groove 43 therein, which registers with the slot 39 in the bar 38, and having openings or'recesses 44 beneath the openings in the plate or board 40, to receive the points 42. The cloth, as shown in Figs. 6 and 7, passes between the plate 40 and the bar 41, but when the bar 38 and the plate 40 secured to the same are raised by moving the same around their pivot bolts 36, the cloth slides freely over the bar 41.

When it is desired to cut the cloth, the bar -forced down untilthe points 42 pass through the cloth'into the openings 44 inthe bar 41. These points hold the cloth securely in position, and to cut the eloth crosswise it is only necessary to insert the blade of a sharp knife 46 into the slot 39 and make a cut from one edge of the cloth to the other. When the guide is'swung up, the springs 45 press the plate 40 outward to keep the points 42 from projecting.

46 are standards arranged at the end of the table 1 on each side thereof, and a `transverse bar extends across from one standard to the other. On this bar are pivotally rPhe inner ends of these` bolts 36 serve as pivot pins for a pair ofv l the weighted bar 48.

" racks 52.

When `the cloth is tovbe laid, the truck 5 of course is adjacent the right -end o-f the table 1, and as it is -moved to the left the handle 17 of th'e gear 16must be turned to pay out the glotlrf-rom thebolt or roll suspended in'the cloth rack' 8.v The" outer end ,of the cloth will be securely held on the table by means `of the weighted bar 48, and

as the cloth is paid out-thetension devicev will cause the two/yers inwhich the cloth is folded to be laid smoothly and evenly, with the weft-*threads arranged? straight across. the table top. When the required length has been paid out, the kbar 38 is forced down to caise the points 42 carried thereby to'stick into the Acloth between the plate 4Qand-'bar 4-1, and the length desired is then severed. j

Fig. 11 illustrates a way ^of laying single ply cloth, when suchclo-th is to be handled. I make use ofthe truck 5.as'before. The cloth is fastened down to the top of the tablel at itsouter end by means of awls 50; and a pair of uprights 51 vis secured to the'sides of the tablev adjacent its end.l Af' similar palr of uprights 52 is secured to the' 35 sides of the table remote from the upright-s v51, and adjacent each of the uprights 52 I place a pair of'vertical racks 52. These racks 52 have a series `of notclies53 on their edgesy adjacent the uprights 52, -to receive a bar54, the said bar beinglonger than the width .of the cloth, so as to reach .from the rack 52 on one side to a corresponding rack opposite. The uprights 51 and 52 and the racks 52 will, of course, be spaced far enough apart toallow the frame 31 to pass `between them. vTo lay the cloth, the vouter end is fastened to the top of the table lby means ofthe awls 50, andthe truck is then moved to` the left, paying out the cloth in the usual Way. When it has `passed to such a distance that the end of the frame 31 clears' the uprightsl 52, itis stopped, and

one of .the bars 54 is laid across the layer o-f cloth, the ends of "this bar lying between the uprights '52 and the racks 52', and rest,- ing in one of the notches 53 carried on the j The truck is then moved back until the bars33 are past the luprights 51, and: a similar rod 54 is then laid across the second fold 4of cloth, so that it will prevent this layer from being pulled back with the truck when the same has vstarted on its nef-t outward movement. The irst'bar 54 c yn now `be removed, as whatever pull is exerted that is, it can be swung around until the rolls 18 and 19 are supported above the rear edge of the truck 5. In this position the cloth can be laid when the truck passes to the' left, by causing it to pass under the pass outward over both the rollers 18 and `19, asIv shown in dotted lines on Fig. 5.

` Figs. 13 and 14 are view s-of acloth measporting arm 55, .attached to the rack 8, and bearing a roller 56. This roller 'rests on 4the surface of the. cloth passing over the roller 14, and \is rotated as the cloth is paid 56, to indicate the number of revolutions.'

Fig. 15 is a view of a modification of a an ,inclined pivoted supportl 58,\'which has longitudinally slotted arms 59 connectedv to its sides'to support thesame in adjusted po- .f"sition. Suitable screws 60, carried in the sides of the truck 57, engage the slotsL in the arms 59, and serve as fastening devices therefor. 61 isa pile of elo-th laid in folds by being passed'over the inclined support 58,

the guide frame 31. This guide frame 31 is adjustable the same by the truck'5. As the pile of cloth .61 is lessened, the support 58 is of course lowered to keep its upper edge approximately level with the top of the pile; While the cloth pile from ,being tumbled or pulled over.

is shownas folded lengthwise, the same as I may use this apparatus to'lay a single ply of cloth as well;l and the same is true of the cloth laying apparatus shown on Fig-2.

It will be understood that the form of t-ruckshown in Fig. 15 is especially useful in handling cloth which is piled in folds or layers in the manner shown in Fig. 1/1, `for the purpose of cutting cloth so filed into the requisite lengths to be worked into the form of garments. I.
