A CORPORATION OF MASSACHUSETTS SETTING FRAME Application filed January 14, 1930. Serial No. 420,781.

The present invention relates to setting frames of the type in which yarn isset on a spool for use in machines for making AX- minster and other fabrics where similar spools are required.

An object of this invention is to make it possible to separate the yarn on the setting spool from the yarn feeding spindles or spools to provide a straight out so as to eliminate waste heretofore occurring. Another object of the invention is to combine with a setting frame or machine, a shearing mechanism which will sever or cut in a straight line the yarn on the setting spool from the yarn on the spindles or spool which feed the setting spool.

Tothese and other ends, the invention consists of certain parts and combinations, of

parts all of which will be hereinafter described: the novel features being pointed out in the appended claims.

Fig. 8 is a section on the line 88, Fig. 7; and

Fig. 9 is a fragmentary end view. According to the present practice, yarn for; Axminster and similar fabrics is'set upon spools by a setting machine or frame which feeds to each spool a number of yarn strands of one color or a combination of colors to be wiped: into the fabric to produce a pile surface. After each spool is fully wound on the setting frame or machine its strands are cut from the strands of the feeding spools or spindles. This cutting has heretofore been accomplished by hand operated scissors or shears and as a result the ends of the yarns or strands on the spool are uneven or ragged, necessitating the trimming of the ends after the removal of the spool from the setting a frame with a consequent waste of the of the yarn cut off in trimming.

According to this invention the yarns on the spool are cut from the yarns on the setting frame in such a manner that the trimming operation is eliminated and with this the elimination of the waste takes place.

In the illustrated embodiment of the invention, the clipping mechanism is shown embodied in a setting machine or frame of known construction. Such a setting machine comprises a main frame 1' having two combs 2 and 3, the former in front of the other and serving as guiding means for guiding the yarn strands a to the spool. Between these combs pass thestrands or yarns from spindles 3 to the spooling mechanism. In this instance, this spool-ing mechanism embodies two parallel spool supporting rollers 4 and 5 on which the setting spool 6 rests. To cooperate with the top of the setting spool 6 while the latter rests on the supporting spools 4 and 5 there is provided a. top roller 7. i This top roller is supported by a swinging frame 8 which is. pivoted at 9 to slides IO'guided on the sides of the frame 1. Springs 11 on opposite sides of the machine connect with the swinging frame 8 and the main frame 1 and tend to hold the roller 7 above and toward the rollers 4 and 5m order to exert pressure on a setting spool 6 supported on the rollers 4 and 5. The top roller 7 is driven by a'chain 12 from the front roller 4 and the latter and the roller 5 are driven in such a manner that yarn passing through the combs or reeds 2 and 3 and attached to the spool 6 will be wound on the spool. To remove the spool 6 the frame 8 is swung forwardly to the position shown in Fig. 3 against rests 13, and after clampingthe yarns in the usual manner the setting spool is placed on the brackets 14 on the swinging frame 8 and has its yarn clipped from the yarn on the setting machine. So far portions described, the setting frame is of a known construction, and further details thereof need not be described in order to understand the present invention, which, in its broadest sense, comprises the combination of a clipping mechanism with a setting machine in such a manner that a clean cut will be made to separate the yarns on a spool from the yarns on the setting frame and thus eliminate the waste and r duce the labor present when the hand clipping and separate trimming is employed.

In the present embodiment, the clipping mechanism is mounted to operate between the front spool supporting roller 4 and the top roller '2' when the latter is in its forward position in advance of the roller 1 and spaced therefrom so that the clipping takes place in advance of the spooling mechanism and while the spool 6 rests on the bracket 14. The clipping mechanism, in this instance, embodies a knife or cutter carrier in the form of a bar having racks 16 depending from opposite ends and guided at 17 on brackets 18 which are bolted to a cross piece 19 forming part of the main frame, the brackets 18 projecting upwardly from the cross piece between the sides of the main frame. These brackets also support a shaft 20 carrying gears 21 at opposite ends and meshing with the racks 16. On the shaft is a pulley 22 about which passes a cable 23 which has its lower end connected to a treadle 24. Depression of the treadle turns the shaft 20 and elevates the cutter or knife carrier to a position where the knives or cutters may operate on the yarns leading to the-setting spool 6 while the latter is on the rests 1 1. After the clipping and the release of the pedal, the yarn clipping mechanism returns to its lower position out of the path of the operating parts of the setting frame The clipping devlces comprise fixed cutters or knives 25 and movable cutters or knives 26. The fixed cutters are in the form of blades arranged in parallel relation on the bar 15 and secured thereto by bolts 27 and 28 one above the other, to project the knives above the upper edge of the carrier 15, the projecting ends being tapered or pointed at 29 so as to provide spaces in which the yarn to be clipped may pass. The movable cutters or knives are blades pivoted to the bolts 27 and also having tapering or pointed ends at 30 so that they may lie, when in normal positions, with their pointed. ends behind the pointed ends of the fixed blades.

' stance, by providing a slidable rack or bar 31 guided on the blade or knife carrier 15 and held thereto by a removable holding plate .32.

his slidable knife operating bar has teeth or QI'OjQCtlODS 33 formlng recesses 3-: between them for receivmg the lower ends of the pivoted knives 26. Operation ofthis slide 31 may be effected by a bell crank lever 35 pivoted at 36 to a bracket 37 on the under side of the carrier 15. One arm of this bell crank lever extends into a recess 38 in the bar 31 and serves by engaging opposite walls of the recess to shift the bar 31 in opposite directions. A spring 39 acts on the other arm of the lever to move the bar v32 in a direction which will cause them to assume the positions shown in Fig. 4 with the bell crank lever against the adjustable stop 40. Movement of the bar 31 in the other direction is effected in this instance, by a link ll pivoted at 4:2 to the bell crank lever and having a longitudinally extending slot 413. \Vithin this slot is projected a fixed abutment 4A supported by one of the brackets 18 and serving as the knife or cutter carrier approaches its uppermost position to engage the wall of the slot at the lower end of the latter and pull downwardly on the bell crank lever, thus causing the bar 31 to shift and the movable knives to cut the different yarns leading to the setting spool.

While the clipping of the yarns is taking place, the setting spool 6 rests on the swinging frame 8 of the top roller 7 as shown in Fig. 3, the top roller being thrown forward and spaced from the front spool supporting roll so that the clipping mechanism maybe moved toward and from the yarn strands between the top roller and the front spool supporting roller I I This clipping mechanism not only severs theyarns, but it acts as a trimmer as all the projecting ends on the setting spool are cut on a straight line, thus doing away with a separate trimming operation and also eliminating the waste of the trimming operation. It will be noted that the clipping mechanism has a plurality of clipping devices, one for each yarn strand leading to the setting spool, and that these clipping devices are arranged in a single line.
