SOLOMON KENDRIGK, F REVERE, MASSACHUSETTS, ASSIGNOR TO EVERLASTIK, INCORPORATED, OF BGSTON, ILIASSAGHUSETTS, A CORPORATION OF MASSA- NEEDLE-LOOM.

Specification of Letters Patent. Patented Feb. 17, 1920- 7 Application fi1ed July 19, 1917. Serial No. 381,631.

To all whom it may concern Be it known that I, SOLOMON KENDRIQK,

I a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Needle-Looms, of which the following is a specification.

This invention has relation to needle looms of the general character of those shown in my Letters Patent Nos. 1,239,60et and 1,239,605, dated September 11, 1917, and has for its object toprovide certain improvements therein for insuring greater smoothness and accuracy of operation, for relieving certain parts thereof from shock and strain, and for securing a more uniform and efiicient delivery of the weft thread to the weft-laying needles.

On the accompanying drawings,

Figure 1 illustrates in end elevation a loom embodying my improvements.

Fig.2represents a front elevation thereof.

Fig. 3 represents a plan view partially in horizontal section.

Figs. 4 and'5 respectively represent front and end elevations of the means for supply- -ing the weft threads to the weaving mechanism.

ported, as will be subsequently explained,

the weft spools, the tensions and the takeups. The loom has the usual batten 13, with as many reeds 14 as there are webs to be woven, said reeds being spaced or separated as ordinarily in looms of this character. The batten is actuated by the crank shaft 15. Any suitable shedding mechanism is employed according to the pattern or character of the web, which may be elastic or non-elastic as desired, certain heddle frames being indicated conventionally at 160. The usual breast beam is indicated at 170.

The warp threads 03 are shown as passing under the intermediate whip rod 51 and thence upwardly to a beam not shown.

The needle mechanism is carried by the breast beam which is provided with rearand having their ends closely adjacent the ends of the corresponding bars of the other pair, as best shown in Fig. 3. Said bars are indicated at 16, 17, 16 and 17. The bars of each pair may be of unequal length, so that one bar 17 may overlap the bar 16. Each pair of bars is operated by a separate mechanism at an end of the loom. To this end, there are outside of the end frames the shafts 18, 18, extending from front to rear and driven from the crank shaft by the gears 19, 19, the combined spur and bevel gears 20, 20, and the bevel gears 21, 21. Said shafts are each provided with two grooved face cams 22, 23, for operating levers 24, 25, which are connected with the needle- operating bars 16, 17, 16 and 17. The cams are so positioned and timed that the needle-operating bars of each pair are reciprocated simultaneously in opposite directions, and so that the corresponding bars 16, 16, or 17 17, are moved synchronously in the same direction as they are reciprocated. Since the looms embodying my invention are relatively wide and capable of weaving a large number of webs simultaneously, I have found that the arrangement of the needle-operating bars, and the separate operating mechanisms therefor at the opposite ends of the loom, permits running the 100m at a higher speed, insures a more accurate operation and effects a greater reduction of operating power than heretofore. The needles 26, 27, as in my previous looms, are in pairs, one pair for each web, and the adjacent needles of the adjacent pairs being pivoted upon the same axis. The needles are slotted at their heel ends, to

- receive pins carried by the operating bars, whereby the needles of each'pair are operloops of weft thread in the shed need not be described, as a full description and ex planation thereof may be found in my said applications. I call attention merely to the fact that the rock shaft which carries said pins is indicated at 28, and it is operated at both ends by earns 29 on the shafts 18, intervening levers and links (not shown "in detail), and slide bars 30.

Since the delivery ends of the needles swing through arcs through the shed and back again, there must be some suitable means for taking up slack between the ends of the needles and the spools from which cross bars 37 38, extending substantially from end to end of the loom, and upright bars 39. Said frame is secured to a support on the arch bars of the superstructure of the loom which may consist of a series of vertical fiat bars 40 bolted to the front arch bar 11. and to the upper frame bar 37. -The lower frame bar 37 rests against and is secured to blocks 41 bolted on the bars 40.

- 44, secured to the under side of a bar 45 located above and in front of the upper line of spools and supported by forwardly and upwardly inclined extensions 46 of the supporting bars 40. Thence the threads pass through similar U-shape wire guides 47 carupwardly inclined extensions 49 of the braces 42. The bars 37, 38, 45 and 48 may be made of wood, and the bars 40, 46, 39,

42 and 49 may be made of narrow flat strips Y or bars of iron. The weft threads then pass downwardly through a reed 50 and under the front whip rod 51, and thencebetween the reeds on-the batten and outside the warp 1 threads, to the eyes of the needles.

To afford a variable tension on the spools any suitable tension mechanism may be employed. As shown, I provide for each spool a plurality of gravity plates 52 which are pivoted on rods 152 and which may be swung upwardly to engage stop or rest rods 53. Any number of the series of four plates for each spool may be swung forwardly to rest upon the spool to afford the desired frictional resistance to the rotation of the spool. Between each spool and the guide 43 or 44, as the case may be, I provide a spring takeup. Each takeup is preferably made of spring wire, the two ends of which are secured to clips 54 on the sides of the uprights 35. The end portions of each wire are then coiled loosely about pins 55 as at 56 and then project forwardly as at 57 to points in front of the associated spool. The side portions 57 then extend upwardly as at 58 and are connected by amiddle portion 59. The thread passes downwardly from the spool under the cross of transverse middle portion 59 of the take-up and thence to v the guide 43 or 44. The portion'59 of each take-up is approximately as long as the spool and is parallel with the axis thereof. As the needles carry the wefts into the shed, the take-ups are drawn upwardly to give up the thread, and, as the needles emerge from the shed. the take-up "takes up the slack. Said take-ups are preferably. made of small gage spring wire to permit them to accomplish their functions to best ad vantage. If desired, the adjacent pairs of spools in the lower line may deliver thread to one pair of needles and the adjacent pairs of spools of the upper line may deliver thread to another pair of needles.

Having thus explained the nature of my said invention, and described a way of makof needle-actuating bars extending from the ends of the loom toward each other for operating said needles in pairs simultaneously in opposite directions to lay two loops of rled by a bar 48 secured to rearward and weft threads in each shed, bar-actuating mechanisms located at both ends of the loom, one operatively associated with one pair of bars and the other operatively assoshed-forming mechanism, a stationary support, a series of pairs of weft-laying-needles,

mechanism for simultaneously operatingthe needles of each pair to lay two loops of weft thread in each shed, and means on the main frame for supplying thread to said needles, elongated spring take-up located between including a supplemental frame for supeach spool and the associated thread guide porting a plurality of spools with their axes to take up the slack in the Weft thread as 10 horizontal, a series of thread guides on said the associated needle moves out of the shed.

5 supplemental frame associated with said In testimony whereof I have alfixed my spools, means for afl'ording a variable fricsignature. tional resistance to the said spools and an SOLOMON KENDRIOK.
