Fig. 20 is a similar view showing the way the cloth is folded when the carrier, similar to that shown in Fig. 14, is employed; and

Fig. 21 is a view of a modified form of construction.

Referring now to the drawings, wherein similar reference characters refer to similar parts throughout the several views thereof, the reference numeral 1 denotes the table, the same being supported upon suitable legs .2, and at either side of the table there is provided a track 3, which extends the entire length thereof.

1 denotes generally a carriage which is employed to carry the free ends of the strips of fabric, and lay them on a table, as will hereinafter be described, said carriage being provided at either side with the side frames 5,'carrying the wheels 6 which run upon the tracks. Thus it will be seen that this carriage can travel from end to end of the table.

Traveling about suitable sprockets 7 and 8, arranged at either side of the machine, are endless bands 9, each of which is connected to the carriage as by means of the connecting pieces 10. One of said sprockets is mounted upon a shaft 11, driven by a pulley 12, by means of a belt 13 from the motor 14. Supported upon the front end of the table is a box 15, having the side walls or frames 16 and 17, each of which is provided with a plurality of slots 18, which slots extend at first downwardly, and then incline forwardly,- as at 19, so that the several slots terminate in vertical alinement, as indicated in Figs. 2 and 12.

At this point it may be noted that this embodiment of my invention is designed to unwind cloth wound upon bolts, such as indicated in Fig. 19, each bolt being provided with'the usual board 20, upon which the cloth is wound.

21 indicates a split rod, which is adapted to embrace the board in each bolt cloth, as indicated in Fig. 13, said rod having the journal 22 at one end and a removable jourml 23 at the opposite end, having the box 24 adapted to engage the free ends of the rod 21; the construction being such that the bolts with their board and journal rods 21 may be inserted in the slots 18, so that when he machine is ready for operation the bolts are in the position shown in Fig. 12 of the drawings.

25 and 26 indicate side frames, one of which is located at each side of the machine adjacent the box 15, said side frames being provided with lateral slots 27, and 28 indicates a plurality of presser rolls, each of which has end journals 29, which are received in slots 27 between the coils of springs 30, one of which is located in each of the side frames 25 and 26; this construction being shown in Fig. 9 of the drawings.

31 indicates, screw threaded adjusting members, by means of which the tension of the springs may be adjusted. The cloth from the bolts passes between these rolls, as clearly shown in Fig. 12 of the drawings.

Located upon either side of the table is a pair of journal boxes 3233 and 34-35; the journal box 32 being directly opposite the journal box 34, and the journal box 33 being directly opposite the journal box 35. Each of the journal boxes has in its lateral portion a vertical slot 36, each of which receives a journal of one of the presser rolls 37 and 38, adjusting screws 39 being employed to engage interposed springs 40, which receive the journals 41 of the presser rolls 37 and 38, whereby the tension of the rolls against the cloth may be suitably regulated.

The reference numeral 42 denotes a knife or cutter, the same being disposed between the presser rolls 37 and 38, and mounted upon a suitable block or carrier 43, the ends of which are carried by side frames 44, said latter frames at each end being provided with suitable plungers 45, which operate in guides 46, one of which is carried by each of the journal boxes 32 to 35. Springs 47 engage with the frame 44 and operate to hold the knife or cutter 42 in its uppermost position.

Connected with the carrier or block 43 are links 48 and 49, which are connected with crank arms 50 carried upon the ends of a shaft 51, which extends transversely of the table 1, underneath the same, and is journaled in suitable bearings 52, formed in the longitudinally extending member 7 53, arranged immediately beneath each edge of the table.

The crank arm 50 is extended. forwardly and is provided with an operating handle 54.

-Thus it will be seen that by means of the handle 54 and the next above described mechanism, the knife 42 may be operated to engage with the cloth upon the table and sever the same. If desired, a slot 55 may be provided underneath the knife, through which the latter may be projected.

Referring now to the carriage mechanism, the latter comprises a base plate 56, rigidly mounted therein and disposed above this base plate at each end thereof are side pieces 57 and 58, each of the latter being provided with an aperture into which is received one of the rods 59 and 60. One of the rods 59 and 60 is carried by each of the side frames or bars 5 of the carriage.

J ournaled in the side pieces 57 and 58 is a shaft 61, provided with an operating handle 62. This shaft has positioned thereon a cam shaft clamping member 63, arranged so that when the shaft 61 is rotated by the handle 62 the cam member 63 can be used to firmly clamp the ends of the cloth against the table or bed 56, so that when the, carriage is moved rearwardly of the table it will pull the ends of the cloth with it.

Threaded upon each of the rods '59 and 60 is a ratchet wheel 64 and ournaled upon an arbor 65, provided upon each ratchet wheel, is a gear wheel 66, a spring-pressed pawl 67 being provided upon the sideof the gear wheel which engages with the ratchet wheel 64.

Supported upon the side pieces 53 are brackets 68 and 69, each of which is provided with a plate 70, which is faced with a plurality of gear teeth 71. These brackets are located near the rear end of the table, and are so disposed that when the carriage reaches that point the gear teeth 71 will engage with the teeth of the gear wheel 66 and rotate the same, whereby the ratchet wheel 64 will be rotated through its connection therewith by means of the pawl 67. This operation will cause a rotation of the ratchet wheel 64, causing the latter to rotate the side pieces 57 and 58 of the carriage, whereby the cam 63 will also be raised or lifted bodily, thereby releasing the cloth. Mounted upon each of the side pieces 57 and between which the cloth passes.

Located along the table at spaced intervals, are brackets 75, each of which carries a plunger 76, each plunger being provided with an inwardly extending arm 77, oppositely located arms carrying a presser roll 78, which is adapted to engage with the cloth, each arm being also provided with a cam roll 79. Plunger 76 is provided at the lower end with heads 80, between which and the bracket operate extens'ile springs 81.

It will be noted that when the'carriage moves lengthwise of the table, the ends 74 of the cam members 72 will enter between the rolls 79 and the table, and elevate the presser rolls 78 so that the cloth may be laid between them and the table; the rolls 79 passing over the cam members 72 during the travel of the carriage.

82 indicates a stop which is fastened to the table and which is adaptedto arrest the movement of the carriage. 83 indicates a bell which is adapted to be operated by an obstruction 84 carried by the endless band or 'chain, the latter at frequent intervals being supported by means of sprockets 85 carried upon suitable brackets supported upon the legs of the carriage.

In Fig. 21 of the drawings I have illus trated a slightly modified form of the invention, in that the cutting and guiding mechanism 86 and the cloth carrying mechanism 87, is supported upon the movable carriage, rather than stationary, as in the embodiment of my invention above described; the construction and operation being otherwise similar to that already described.

In the embodiment of my invention first above described, the cloth is adapted to be carried upon the rods 21. This in the event that a roll or bolt of cloth, such as shown in Fig. 19, is to be utilized. In the event that a roll, however, such as shown in Fig. 20, is utilized, I'preferably provide a plurality of pans 88 adapted to receive the bolts of cloth and from which they are unwound.

Having thus described this form of embodiment of my invention, the operation thereof, which should be largely obvious, may now be described.

Assuming the bolts of cloth to be mounted in the ends of their supporting slots, as

shown in Figs. 2 and 12 of the drawings, the ends of said strips of cloth are inserted between the rolls 28 and are thence passed beneath the rollers 37 and 38 and the ends thereof are then lifted upon the table 56 of the carriage 4 and clamped thereto by the cam 63 operated by the handle 62. The machine is then started by shifting the belt 13 to the driving pulley, whereupon the endless chain 9 will move the carriage rearwardly, carrying the ends of the cloth with it, thereby drawing the cloth from the bolts and separating it upon the table 1. As each guide roll 78 is reached, the end 74 of each cam member 72 will engage with the cam rolls 79 and lift the presser rolls, so that the cloth may be passed under them, whereupon by the passing of the carriage the roll 78 will again be permitted to descend under the influence of the springs 81, whereby they will again engage with the cloth upon the table. Then the carriage has reached the rear end of the table the gear teeth 71 of the plates 70 will engage with the gear wheels 66 and rotate them, and thereby the ratchet wheels, whereby the cam 63 will be lifted bodily, thereby disengaging the cloth and allowing the ends thereof to fall downwardly, it being noted that the plate 56 of the carriage is elevated so that upon a return of the carriage, said plate will pass over the cloth piled upon the table. When the carriage has passed rearwardly far enough to permit th dropping of the ends of the cloth upon the table, the projection 8% upon the endless belt will ring the bell,

notifying the operator to reverse the carriage, which is accomplished by reversing the driving mechanism. In this connection it may be noted that a second crossed belt 89 is provided, which is engaged with the fixed pulley wheel 90, and will operate to reverse the mechanism. In the event that the operator does not promptly reverse the carriage, the stop 82 will engage with the arm 10, which is attached to the bell carriage, and hold the parts stationary, until the operator reverses the driving connections of the carriage.

When each layer comprising several thicknesses of cloth has been laid upon the table, the knife 42 is operated to sever the cloth, whereby the operation above described may be repeated.

It will accordingly be seen that I have provided a machine well adapted to attain, among others, all the aims and objects above pointed out, in an exceedingly simple yet efficient manner.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.
