To (1Z3 whom it may 00mm.-

Be it known that I, MoR R Is Doii MAri; a

citizen of the United states, residing'lat Baltimore, lvlaryla'iid, have invented certain new anduseful"lmfiiovem'ents in 1010a; Laying and"Folding lsfachine; of which the tollo'wing'is' a sp'cificatioii. I

This invention relates to cloth layingand folding machines audit consists in the novel features hereinafter described and claimed. An object of the invention is to provide in combination with afclo'th cutting 'table, a

carriage ada'pte d to move over the table and carry one or more rows, bundles or v bolts ofthe cloth and lay'the cloth in superposed layers upoi 'th'e surface of the table in order that a stack otthe" pieces ot'the cloth may be cut tromthe folded layers of thecloth by thecloth cutters and in th'usual' manner.

A' further object of t11ai11v rii01iig to; provide means for cont rolli ng the movement of the carriage so that the cloth will be laid evenly and smoothly upon the table and in superposed layers of uniform length.

A] still further object'ot' the in vent i'on is to provide upon the carriage cutting ap paratus or means adapted to sever a remant from the roll, bundle or bolt ot cloth in order that the end edge of the' last' layer wl'lich. is'laid may occur at certain 'predetermined points upon the top of theJt-able so that when the patterns are applied to the upper layer of cloth for the purpose of cutting out a stack of pieces, all of the pieces in thestack will be full and complete, thereby economizing in the use of the cloth andi assuring that allof the pieces in each stack of pieces are in proper cOnditiohfOr use in the make-up'of a garment. Other objects will he made manifestas the'description of the machine progresses. v

VVith such objects in view the invention includes a cutting table having a series of linear IIlflSlH'ElnBnf; marks disposed along one or both of the longitudinal ed'ges of the top 'thereof Tracks are embedded in the 'uppersurface of the table top the said tracks being 'U-shapd in transverse section. The tracks are provided at theiriopposite ends with slidable sections adapted to move longitudinally of the tracks -when the carriagemoves upon them and changes its direction of movement over the tracks: This to prevent'the wheels 'ofthe carriage from slipping when thecarriage is changing its FOLDING MACHINE.

The cloth laying and folding machine in cludes a table 1 having a series of linear measurement graduation marks 2 provided along the longitudinal edges of its top. These graduation marks may be in units of yards or units of any other lengths. A cloth clamping or securing device, indicated in general at 3 is mounted at one end of the table 1. Parallel track rails 4 are embedded in the upper surface of the top of the table 1 and extend longitudinally of the table. The said track rails are U-shaped in transverse section as best shown in Figure 3 of the drawings. A carriage 5 is mounted for movement longitudinally over the top of the table 1 and the wheels 6 of the car-- riage travel upon the intermediate portions of the track rails 4'. A platform 7 is attached to one end of the carriage 5 and is arranged to move along one of the side edges of the top of the table. An operator may stand upon the platform 7. The carriage 5 is provided at. the upper portions of its ends with upstanding arms 8 which. may carry rolls 9 of the cloth or the space between the arms 8 at the opposite side poi tions of the carriage may be utilized for holding loose bolts or furled bundles of the cloth. In Figure 2 of the drawing, a roll of cloth 9 is illustrated as being supported at the upper end of one set of the arms 8. Shear levers 10 are pivoted at the ends of the carriage 5 and as shown in Figure 9 of the drawings these levers are provided at one end with sockets 11 which slidably receive studs 12. Springs 13 are also housed in the sockets 11 and are connected at their outer ends With the inner ends of the studs 12 and are connected at their inner ends to the intermediate portions of the levers 10. Cutting blades 14 are. carried at the outer ends of the studs 11 and are disposed transversely across the carriage. The opposite end portions of the shear levers 10 are longitudinally slotted as at 15. A plate 16 bridges the space between the slotted ends of the shear levers 10 and the said plates carry pins 17 which are received in the slots 15, The plate 16 is mounted upon a shaft 18 which is pivoted in the end of the carriage 5 and which is provided with a crank arm 19. A rod 20 is pivotally connected at its upper end with the end of the crank arm 19 and extends down along the hanger which supports the platform 7 and is provided at its lower end with a treadle 21. From the roll 9 the cloth is trained through the space between the cutting edges of the blades 14 the end edge portion of the cloth is secured to the top of the table 1 by the clamp or securing device. Thus the end of the cloth is held at a fixed point upon the table and as the carriage moves over the top of the table the cloth is unreeled from the roll and moves between the cutting blades 14: and is stretched in layers, in superposed relation as will. be explained hereinafter, upon the table top. When the length of cloth is unwound from the roll 9 the carriage 5 is brought to a state of rest, as will be explained hereinafter, and the operator places his foot upon the treadle 21 whereby the rod 20 is moved longitudinally and the plate 16 is turned with the shaft 18 thus drawing the slotted ends of the shear levers 10 together and moving the blades 14 to- Ward each other. Thus the blades sever the remnant from the cloth and produce a square cut edge at the end layer of cloth.

Cloth folding means are mounted upon the table 1 substantially at. the end of the path of movement of the carriage 5 thereon and each of these means includes a block 22 having a transverse opening 23 therein as best shown in Figure 13 of the drawings. The opposite end portions of the opening 23 are offset with relation to each other thereby providing interiorly located shoulders 24 in the said opening. A pivot pin 25 passes vertically through the block 22 and bridges the opening 22 at a point midway between the ends thereof. An arm 26 is pivoted at a point midway between its ends upon the pin 25 and the end portions of the arm which lie at the opposite side of the pivot 25 have angularly disposed portions 27 and 28. When the portions 28 of the arm are disposed at a right angle to the sides of the block the portions 27 0f the arm are in engagement with the shoulders 24 and are normally held in engagement with the said shoulders by a coil spring 29 (best shown in Figure 14) which is connected at one end with the arm and which is connected at its other end with the block 22. The intermediate portion of the spring 29 is coiled around the pivot 25. The portion 28 of one of the end parts of the arm 26 is provided with a hinged section 30 and the said sec tion 30 is normally held in alignment with the inner portion of the arm by means of a spring 31. The pivotal connection between the section 30 and the adjacent portion of ionthe arm is in that form which is commonly known as a rule joint and that is to say the section 30 may swing in one direction with relation to the arm and against the spring 31 but should the section 30 be moved in an opposite direction the arm 26 is swung with the section 30 and upon the pivot Depending fingers 32 are carried by the carriage 5 and the sections 30 of the cloth folding arms are located in the paths of movement of the fingers 32. When the carriage is moving toward one of the sets oi blocks 22 at one end portion of the table 1 and as the carriage is laying a layer of the cloth upon the table 1, the finger 32 strikes the section 30 of the cloth folding arm and swings the said arms to the position indicated by the dotted lines in Figure 13 of the drawing. Thus the inner portions 28 of the arms 26 are moved out of the lay of the cloth and therefore a length of cloth is spread upon the table 1 or upon the uppermost layer of cloth which has been previously spread thereon. As soon as the carriage 5 passes beyond the outer ends of the blocks 2, the fingers 32 clear the outer ends of the sections 30 of the arm and under the tension of the springs 29 the arms 26 are returned'tothe full line position shown in Figure 13 of the drawing whereby the inner portions 28 are disposed transversely over the edge portions of the uppermost layer of cloth which has been spread upon the table. Upon the movement of the carriage 5 in a reverse direction the cloth is carried around the inner portions 28 of the arms and a fold line is established at the end of the uppermost layer of cloth. Continuing on its reverse movement the pins 32 carried by the carriage 5 strike the pivoted sections 30 of the arms 26 at the sides thereof opposite those sides against which the springs 3'] bear and in that the arms 26 are held against turning movement by the engagement of the portions 27 with the shoulders 24 the sections '30 swing upon their pivotal connection with the outer portions 25% of the arms 26. and against the tension of the springs 31. As soon as the fingers 32 clear the outer ends of the sections 30 of the arms 26, the said sections are swung into alignment by the springs 31 with the outer portions 28 of the arms 26. Thus the cloth folding means are actuated and removed from the lay of the cloth.

Each of the rails of the track 4 is provided at its ends with a longitudinally mm able section 3?). Springs 34 bea r against the outer ends of the sections it; and serve to hold the inner ends of the sections 33 toward the intermediate section of the track rails 4. When the carriage 5 moves upon the section33 at the same ends of the tracks 4 the said sections 33 under the weight and the inertia of the carriage move slightly in the Same direction as that in which the carriage is moving and press the adjacent springsiit it this time the carriage about to change its direction of movement over the track rails and approximately at this time the supporting wheels of the carriage are caused to rotate in a direction opposite to that in which they were rotating when they approach the movable track section. The reversal of the rotary movement of the supporting wheels of the carriage will be explained hereinafter. As the supporting wheels of the carriage reverse in their turning moven'lent, the track sections 33 under the influence of the springs 34-, tend to move back to their normai positions with relation to the intermediate sections of the track rails Therefore the said track sections 33 move slightly with the wheels and the wheels will not slip upon the said track sections. l urtherniore this relative movement of the track sections with relation to the table serves to stretch the layer of cloth which has just been laid upon the table top. The track sections 33 are supported upon the rollers 35,best shown in Figure 11 of the drawings, in order that the said track sections may move without friction Gap tillers 36 are pivoted upon the table 1 and are curved longitudinally a shown in Figure l of the drawings. Lilli-ls 37 are pivotally connected at one end with the sections 2}?) and pivotally connected at their other ends with the gap fillers so. \Vhen the section 233 moves with relation lo the intermediate portion of the track 4 the link 37 is moved longitudinally whereby the curved gap fillers so is swung upon its pivotv and its free end is interposed between the end of the track section 33 and the adjacent end of the intermediate section of the track as indicated by the dotted lines in Figure '10. Therefore when the wheels of the carriage pass over the gap between the ends of the sections 33 and the adjacent ends of the intermediate sections of the track, the wheels travel upon the upper sur faces of the gap fillers and consequently the carriage is not jolted nor does it create noise in passing over the gap. When the sections 33 are returned to their normal positions with relation to the intermediate se tions of the tracks 4 the gap fillers 86 are returned to their normal positions as indicated by the heavy lines in Figure 10 of the drawing.

The machine is provided with a series of jacks located at intervals along the tracks 4 and which are adapted to be used for lifting the carriage slightly above the surfaces of the track rails when the carriage comes to a stop and during the operation of cutting the remnant from the last layer of the cloth. These jacks are provided at their upper portions with rollers upon which the wheels of the carriage move so that the wheels of the carriage may continue to re tate but the carriage remains stationary upon the track rails. The jack mechanism also includes cheek devices which include sections of the track rails pivotally mounted and adapted. to be swung up in the path of movement of the wheels of the carriage in order to hold the carriage against movement longitudinally of the tracks during the cloth cutting operation as stated. The jack mechanisms are so positioned and distributed along the table that the carriage is brought into a state of rest at such points upon the table top that when the remnant is cut from the laid layer of cloth the edge oi the said layer of cloth will be in align ment with one of the linear graduation marks This is essential in that during the process of cutting the stacks of pieces from the superposed layers of the goods the patternsare applied to the upper layer ofthe cloth and the edges of the patterns do not extend beyond transverse lines across the table from the said graduation marks. Therefore it is definitely known that when a stack of pieces is cut from the superposed layers of the cloth that each piece in the stack will be complete and conse quently all of the pieces in the stack of pieces will be utilized in making up the garment.

The track rails 4 are provided at intervals with openings and guide members 41 which depend from the under sides of the track rails and each guide member surrounds a group of the openings 4(). Blocks 42 slidably mounted in the guide members 41. and carrying at their upper portion jourualed rollers 43, the upper portions of which are adapted to be projected through the openings 40 when the blocks 42 are elevated in the guide members 41. Rods 44 are pivoied at the under sides of the top of the table 1 and rods 44 extend under the lower ends of the blocks 42. Shafts 45 are jourualed under the top of the table 1 and are provided with cranks 46 upon which the free end portions of the rods 44 rest. The shafts 45 are intended to be turned manually and when they are so turned the cranks 46 rotate about the axes of the shafts and the free end portions of the rods 44 are lifted whereby the blocks 42 are elevated in the guides 41 so that the rollers 43 are projected through the openings 40 and the upper por tions of the rollers are. disposed above the upper intermediate surfaces of the tracks 4. These rollers 43 move under the wheels of the carriage 5. as hereinafter described, and the carriage is lifted slightly with relation to the tracks. The wheels of the carriage may continue to rotate but the carriage will not move along the tracks in that the said wheels are supported upon the journaled rollers 43.

The track rails 44 are also provided with hinged sections 47 having openings 48. guide member 49 depends below the track rails and a block 50 is slidably mounted in the guide member. Said block 50 is provided with chamfered upper corners 51 at which chamfered corners rollers are journaled as best shown in Figure 8 of the drawings. The shafts 45 are also provided with cranks 53. the outer ends of which are connected by links 54 with the lower ends of the blOcks 50. Therefore when the shafts 45 are turned as hereinbefore described the cranks are rotated about the axes of the shaft. the links 54 are moved longitudinally and the blocks 50 are elevated in the. guide ways 49. The upper edges of the blocks swing the sections 47 to open position as indicated by the dotted lines in Figure 8 of the drawings and simultaneously the upper portions of the rollers 52 are projected through the openings 48. Thus the sections 47 which are moved to inclined positions serve as checks for the wheels of the carriage as indicated by dotted lines in Figure 8. The wheels of the carriage come into contact. with the rollers 53 whereby the wheels of the carriage may continue to rotate but the carriage is brought to a state of rest upon the table. At the time the carriage is brought to a state of rest the remnant of the cloth is cut from the uppermost layer which has been deposited upon the table or the pile of cloth upon the table and the edge of the cloth which forms the uppermost layer will fall upon the pile of layers and will be in alignment with one of the graduation marks 2 provided upon the tahle top.

A motor 55 is mounted for swinging movement upon the carriage 5 as best indicated in Figure 4 of the drawing. The shaft of the motor 55 is operatively connected with a terminal gear wheel 57 by means of a gear transmission 56. A lever 58 is fulcrumed upon the frame of the carriage 5 and carries a gear wheel 59 which meshes with the teeth of the gear wheel 57 as shown in Figure 6. Gear wheels 60 are mounted upon the axles of the wheels of the carriage 5 as shown in Figure 6 and a gear wheel 61 meshes with the teeth of one of the gear wheels 60. The wheel 59 is located between one of the gear wheels 60 and the gear wheel 61. The levers 58 may be swung upon the carriage 5 so that the wheel 59 may be brought into mesh with the adjacent wheel 60 or the lever 58 may be swung so that the wheel 59 may be brought into mesh with the wheel 61. The wheel 59 at all times remains in mesh with the teeth of the wheel 57 therefore means are provided for transmitting rotary movement to the axles and wheels of the carriage in opposite directions as the lever 58 is shifted. Pawls 62 are pivoted under the trame of the carriage and are adapted to encounter lugs 53 mounted upon the top of the table 1. The tree ends of the said pawls are adapted to enga e a rack bar (34 which is earried hy a pivoted arm 5 having engagement with the outer end of the lever 58 hereinbefore described.

The table 1 is provided in the vicinity of one of its longitudinal edges with a longitudinally disposed conduit on having electric terminal bars 67 located therein at the opposite sides thereof and spaced from each other. A plow 68 is connected with the carriage 5 and enters the conduit (30. The said plow 68 carries contact plates 69 which are adapted to move along the terminal 67 and in contact therewith. The plow carries electric wires 7 which are connected at one end With the contacts (39 and at their other end with the motor mounted upon the earriage. The terminals 67 are energized by an electric current in the usual manner (not shown or diagrammed), and from the contacts 67 the contacts 69 and the wires 70 convey the current to the motor and operates the same.

As the carriage moves from end to end from the table the holding pawls strike the stops upon the table and release the motor so that the motor is swung upon the carriage. This also swings the gear transmission and the terminal gear of the said transmission is moved from the gear wheel upon one axle of the carriage toward the gear wheel which operates the other axle and the said gears are automatically located to the shifted position. Thus the carriage automatically reverses its movement at the ends of the path of travel upon the tracks as hereinbefore explained and contemplated.
