TEXTILE-MACHINE.

Specification of Letters Patent.

Patented Sept. 23, 1919.

To all whom it may concern Be it known that we, EDWARD LA CHANGE and Josrrn D. PENNELL, citizens of the United States, and residents, respectively, of Aurora, Kane county, Illinois, and East Boston, Massachusetts, have invented an Improvement in Textile-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to textile machines, being more particularly concerned with machines for selecting and separating warp threads and presenting them successively to the action of some mechanism, such for example as a thread-placing device. For purposes of illustration the invention is herein shown embodied in a warp drawing or thread placing machine where the threadplacing device is utilized for placing the warp threads through drop wires, harness eyes and reed dents. \Vhile having particularly advantageous application to a machine of this class it is susceptible of broad application to machines intended for other or similar purposes than drawing-in machines wherein the selection and separation of warp threads is required.

The character of the invention will be best. understood by reference to the following description of an illustrative embodiment thereof shown in the accompanying drawings, wherein:

Figure 1 is a side elevation of a portion of a drawing-in machine embodying the invention;

Fig. 2 on an enlarged scale is a plan of a portion of the machine shown in Fig. 1;

Fig. 3 is a plan of a portion of themachine forming a continuation of the portion shown in Fig. 2;

Fig. 1 is a vertical section taken on line 4; 1 of Fig. 2;

Fig. 5 is a section taken on line 55 of Fig. 3; and

Fig. 6 is a side elevation of the mechanism shown in Fig. 5.

While the invention in many of its aspects is applicable to machines other than warp drawing machines, well as to Warp machines of other types and constructions than the specific one shown herein, we have herein illustrated the invention by embodi ment in a well known type of drawing-in machine which is partially shown in Figs. 1 and 2.

The machine here shown may be of the same general construction as the type of machine shown in British Patent No. 4,661 of 190%. and United States patent to Charles Lea, No. 1,153,869, and United States application of Charles Lea, Serial No. 692,468.

In the illustrated form of machine, as is well known to those skilled in the art, the heddles, warp threads and drop wires or other similar loom elements which may be employed are supported in a general parallel arrangement lengthwise of the machine upon suitable supports carried by the main bed or frame 1 of the machine. An appropriate needle 3 or other thread placing device together with suitable needle reciprocating mechanism, is carried by the traveling carriage 5 and caused to traverse the extent of the reed r and hcddles h, warp and drop wires 4.0 and place successive warp threads through the desired heddle eyes or selected reed dent and drop wires, these being appropriately positioned for this purpose in the needle path by suitable selecting and positioning mechanism.

The drawing-in needle may be operated in any suitable manner. As shown herein it is actuated from the main operating shaft 7 through a train of gears 9, 11, 13 and a shaft 15, the latter carrying a crank wheel 17 connected by a rod 19 with an arm 21 the lower end of which is fulcrumed on the end of the carriage 5, referred to, and the upper end of which is connected by a link 23 with the needle holder which slides in a guide 25.

The separate banks or groups of drop wires are provided with releasing shafts '27, worms 29 and worm shafts 31. To rotate these shafts there is provided an actuating shaft 33 adapted to be driven by a pattern mechanism, as more fully hereinafter de scribed, said shaft being connected by a universal joint with a shaft 35 carrying a small pinion 37, the latter meshing with the larger gear 39 provided with an eccentrically arranged pin 11 working in a slottedarm 13 carried by a vertical slide 45 whereby the latter is given a vertical reciprocatorv movement. The upper and; of the slide has: its

opposite sides provided with teeth which mesh with small pinions 47 receiving equal but opposite rotation. Said pinions are secured to shafts 49 provided with chucks 5-1 V relates to the warp separating, selecting and feeding mechanism whereby a plurality of groups of unseparated warp threads may be handled so that a thread may be drawn in from either. For purposes of illustration, two warp worms 57 and 59 are shown on shafts 61 and 63 and each comprises a frusto-conical fluted portion which first re ceives, disentangles and separates the warp threads, and a selecting, spacing and feeding screw or worm portion by which the threads are presented to the hook of the drawing-in needle successively. The shafts 61 and 63 are journaled in hearings in a frame projecting from the carriage 5, referred to. The worm 57 is located slightly above and in advance of the worm 59 so that both are within convenient range of the drawing-in needle.

' The worm shafts 61 and 63 converge slightly toward one another and present their driven ends in superposed relation, as shown in Fig. 2. The shaft 61 has loose thereon a gear 65 driven by a larger gear 67 driven in turn by a pinion. 69 on a stud shaft 71, the latter carrying a miter gear 73 meshing with a miter gear 75 on an inclined shaft 77 journaled in bearings in brackets 79 and 81 secured to the carriage. The shaft 77 has at its lower end a miter gear 83 driven by a miter gear 85 on a sleeve shaft 87 splined to the main driving shaft 7, referred to. The shaft 63 has loose thereon a sprocket wheel 89 driven by a chain 91 from a sprocket wheel 93 fast on a shaft 95 driven by a pinion 97 fast on said shaft from the gear 67 referred to.

The pinions 65 and 97 are adapted to be clutched to their shafts to rotate the worm shafts at the times desired. As shown herein the pinion 65 has a clutch 99 and the pinion 97 has a clutch 101. These clutches are con trolled by spring pressed rods and a pattern mechanism substantially similar to those disclosed in said application Serial No. 692,468. This pattern mechanism comprises a cylinder 103 provided with perforations which are adapted to be brought into regisis connected to said shaft and rotates the be used. for each group if desired.

"tration with a row of feeler bars 105, each of which is provided with an intervening blank or separating washer 107. V

With each retraction of the drawing-in needle the clutches of the pattern mechanism are thrown into engagement to connect the driving devices of the worm shafts therewith, but are immediately released unless held' therefrom by the interposition of a washer in the path of a plunger rod. If for example the pattern mechanism operates to interpose the washer 107 in the path of r the clutch operating rod for the driving. pinion 65 of the worm shaft 61, said pinion same until the clutch is released by the pattern mechanism. Similarly if the driving pinion 97 of the worm shaft 63 is clutched to its shaft said worm shaft will receive rotationuntil the clutch is released by the pattern mechanism.

One group of warp threads 109 is led from an appropriately supported warp beam 111 through a clamp 113 mounted on a carriage 115 similar to the warp carriage shown in the British patent referred to, and is led thence about the worm shaft 61 to a clamp 117 adjustably mounted on rods 118 projecting from the carriage 115. Another group of warp threads 119 is led from an appropriately supported warp beam 121 through said'clamp 113 about the worm shaft 63 to the clamp 117. The warp threads may be put under proper tension for the operations of the feeding, separating and selecting 100 worms by adjusting the clamp 117 along the rods 118. .While the. same clamps are utilized herein for both groups of threads it will be understood that separate clamps may It will be apparent that the pattern mechanism may be constructed and arranged for operating either the worm shaft 61 or the worm shaft 63 in any combination or sequence desired. They might be operated alternately to present warp threads to the needle or a plurality of threads might be presented by one followed by the presentation of a plurality of threads by the other,

or they might be operated simultaneously to present threads to the needle so that two warp threads would be drawn in at the same time.

One of the warp beams may carry the bulk of the warp threads and another may carry a small number of threads. For example, ten threads might be selected in succession from one warp. beam and then one thread might be selected from the other,

thereby arranging the threads for produc- 125 may be arrangedin two or more groups on n l a and-.ais gle ea n y mp y d n c njun t n w thh m ne WVhile the invention is. illustrated herein specifically with reference to its embodiment he e c ina mechani m- Q he Speci i yn shown, her o m of lec ins maybe used within' thebroad principles of the invention.

While the mechanisn't is disclosed herein for'presenting-merely two groups of warp threads to the needle, it will'be understood that a larger number. of groups of threads might be usedl Although the selecting mechanism described herein for presenting thethreadsto the needle of adrawingin machineitis not restriotedto this use,'but is scilisceptible of other( applications as des1re Having described one illustrative embodiment of the invention without limiting. the same thereto what we claim as newanddcsire to secure by- LettersPatent. is:
