MOSES ISAACS, OF NEW YORK, N. Y.

. CLOTH-LAYING MACHINE.

Application filed November 6, 1917.

To all whom it may concern:

Be it known that I, Mosns IsAAos, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Cloth- Laying Machine, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide means for drawing and laying cloth b from a soft-center roll or bolt; to avoid the necessity of supporting a roll or bolt of cloth on a rotating member on a laying machine; to insure an even tension for the cloth while being laid; to provide an adjustable guide for laying the cloth; to avoid excessive tension on the cloth during the operation of laying the same; and to provide means for applying or laying cloth so that the faces of the different layers of cloth will be opposed, without reversing the design or weave characteristics.

Drawings.

Figure 1 is a top plan view of a machine constructed and arranged in accordance with the present invention, the same being shown in conjunction with a portion of a cloth-laying table and with a retaining clamp used in connection therewith;

Fig. 2 is a longitudinal section, the'section being taken as on the line 22 in Fig. 1;

Fig. 3 is a side view of a carriage for a cloth bolt constructed and arranged in accordance with a modified form of the invention;

Fig. 4 is a side view of a modified form of the invention.

Description.

The cloth to which this invention relates is such as is delivered in rolls that have been rolled up on a rod or bar andthe rod withdrawn leaving no definite aperture into which to reinsert a rod or bar for unwinding or laying up, and to insert one there would be danger of tearing the cloth.

The bolts 8 shown in the drawings, are of the character above mentioned, from which the rolling rod or board is absent. To facilitate the unrolling of the cloth from the bolt, a cradle is provided having supporting rollers 9. The rollers 9 are arranged as shown best in Fig. 2 of the drawings, and are mounted in frictionless bearings, such as Specification of Letters Patent. I

ball or roller bearings, provided in end frames 10. The frames 10 are mounted at opposite ends of a platform 11, and are reinforced by tie-rods l2 and 13. At the center of the platform 11, a swivel plate 14 is secured. The plate 14 operates in conjunction with a wearing plate 15 to serve as a turntable for the cradle and platform therefor. A pivot or king pin 16 extends through both plates 14 and 15 to maintain the concentric relation thereof. Positioning pins 17 are provided in the plate l-il to register with indents or sockets formed in the plate 15. The pins and sockets referred to are so arranged that the platform 11 and structure supported thereby may be rotated one-half of a revolution after being disengaged and before rengaging. The cradle and connected structure are supported in service on a carriage having side bars 19 and carrying wheels 20. The wheels 20 are of the grooved type to run on track rails 21 with which a cutting table 22 is furnished. The table 22 is usually equipped with a clamp 23, the head of which is provided with prick points or other retaining devices which hold the severed edge of the cloth.

To guide the cloth as the same is delivered from the machine, the cradle has rollers 24 disposed laterally to the center of the cradle and to the normal center of the bolt 8. At opposite sides of the machine and of the rollers 24, are guide rollers 25 and 26. A guide rod 27 is held between the laying arms 28. The arms 28 are pivotally mounted, a shaft 29 being rigidly held thereby and having bearings in the side bars 19, as shown best in Fig. 2 of the drawings. The arms 28 are adjusted to their working position by means of a hand nut 30. The nut 30 extends through guide slots 31 formed in quadrant plates 32, as best shown in Fig. 2 of the drawings. The slots 31 are concentric with the shaft 29. The arms 28 are structurally connected by means of a tie rod 33 and the guide rods 27 and 34.

When using a machine constructed and arranged as above described and as shown in the accompanying drawings, the cloth may be laid from end to end of the table, separate retaining devices being located at each end of the table.

When employing the machine in this manner, it will be found that the cloth is deposited on the pile by means of the rods 27 and 34 alternately. The cradle and platform on which it is mounted are not rotated.

When, however, it is desired to lay cloth so that the successive layers shall rest face to face and back to back, the cloth is held by the clamp 23 at one end only of the table and is severed at the opposite end of the table on each oscillation of the machine The platform 11 and cradle are rotated at the end of each return trip and the severed end of the. cloth is then rte-threaded under the shaft 40, which extends between the frames rollers and over the rods 25 or 26 at the op posite side of the cradle. It is obvious that when rearranging the cloth in this manner, it is reversed in relation to the layer previously deposited on the pile. If the cloth have a nap, it is obvious that by thus reversing the successive layers, the arrangement of such nap on the completed garment is. uniform. It 1s also obvious that though the cloth is delivered from what maybe termed a soft-center roll, the pull or tension thereon is slight and uniform.

In Fig. 3 of the drawings, a modified form of the cradle is disclosed. The modification consists in providing frames 35 shaped substantially as disclosed in said Fig. 3 of the drawings, the side members whereof have pin holes 36 for engagement by pins 37 The pins 37 extend through the holes 36 to engage holes 38: in straight side arms 39. The side arms 39 are pivotally mounted on a 35 and provide bearings for rollers 41. As shown by dotted lines in Fig. 3, the side arms 39 and rollers 41 carried thereby, may

be disposed in a flat or outstretched position.-

This arrangement of the frames and rollers facilitates the mounting of the bolt 8 thereon. In this position also, if desired the ap paratus may be employed for laying folded cloth which. is then deposited upon the rollers upon. a board resting thereover.

After the bolt 8 has been deposited on the frames; 39 and rollers 41, the said frames are lifted to any desired angle and there held by the pins. 37 which are inserted through the holes 36 and 38 of the frames 35 and side arms 39. The frame 35 and parts connected therewith are'pivotally mounted on a carriage having the side arms 19', in the guiding the clothas it is unwound from the roll 8. It will be noted that the frame 45 has the king pin 16- and is adapted to be reversible rotated on the carriage above described.

' When using the modified form of the invention described, the cloth is alternately passed over the rollers 46'and1 47 or over the roller 46 alone, inaccordance with the position of the roll 8 on the supporting carriage. Claims.
