Application filed June 6, 1913. Seria1No.772,141.

My invention relates to a warping ma-"- chine and more particularly to mechanism for shifting the warp threads along the reeds to prevent/the cutting or wearing away of the reed.

A practical embodiment of my invention is represented in the accompanying drawings in which,

Figure 1 is a view of the machine in side elevation. Fig. 2 is an enlarged face View of the reed and parts associated therewith. Fig. 3 is an end View of the same looking transversely across the machine, certain parts shown in section, and Fig. 4 is'a vertical section in the plane of the line AA., Fig. 2.

The frame of the machine is denoted by 1, and may be of any well known or approved construction for supporting the several operative parts. The reel for winding the yarn is denoted by 2, and is mounted in suitable hearings, in the present instance, on roller bearings 3, supported upon suitable brackets 4 on the main frame.

In Fig. 1, the reel shaft 5 is shown provided with sprocket. wheels 6, of the same size and number of teeth for receiving sprocket chains 7 and 8, the former leading to a drive sprocket wheel 9, at one end of the'machine and the latter leading to a driven sprocket wheel 10 at the opposite end of the machine, so that the operator by means of a crank 11, on a shaft of the sprocket wheel 9, may manually. operate the parts to set them in proper position for starting under power. The gear wheel 12, shown at the right hand end of themachine in Fig. 1, and the gears immediately associated therewith, are parts of the beaming mechanism, the same forming no part of my present invention and are indicated here simply to show the relation of the beaming mechanism to the warping or reeling mechanism.

The reed frame through which the warp.

given the usual transverse motion by means of a worm on the shaft 20, on which the sprocket. wheel 10 is located, which worm enga es a worm wheel 21 on a short shaft 22, to latter carrying a pinion 23 which engages a stationary rack 24, causing the reed frame support 25, together with the reed frame, to travel laterally across the machme. A hand wheel 26 serves to return the frame to its point of starting.

In cooperative relation to the reed frame 19, there is a guide bar 27, over which the warpspass after passing through the reeds, and n order to prevent the warp threads from frictional contact with the several reedscontinually in the same position, the bar 27 is arranged to be moved verticallv. therebyshifting the posit-ions of the Warp threads relatively to the reeds, so that theV Wlll frictlonally engage the reeds in different posltions at the pleasure of the operator and thereby prevent wearing grooves and cuttlng out-the reeds. To thisend, the bar 1, A CORPORATION OF NEW- 27 is supported on vertically movable bars' I 28, 29, held in lugs on the ends of a swinging frame andinormally depressed by means of springs 31, 32, interposed between collars 33, 34,0n the bars 28, 29, and lugs on the frame 30. The upper endsof the bars 28, 29, are provided with branching brackets 35, 36, 111 the ends of which the opposite ends of the bar 27 are supported, the intermedlate portion of. the said bar being supported by means of lugs 37, 38, 39, on 'a bar 40, connecting the heels of the brackets 35, 36. This serves to hold the guide bar '27 in a true horizontal position.

The swinging frame 30 is supported on a rotary shaft 41 mounted in depending arms 42, 43, of a yoke piece 44, bolted to the arms of a head piece 45 on the rear end of the support 25, and said shaft 41 has fixed thereon two ratchet toothed cam wheels 46, 47, located respectively beneath the bars 28, 29, the lower ends of the said bars being each provided with a tooth 48, 49, which loo bears directly on the face of the cam. The

said shaft 41 also has thereon a sprin '52 located between a collar 53 on the s aft and the arm 42 of the yoke piece 44, which spring is under compression and serves to frictionally hold the swinging frame in position-against any tendency on the part of the yarn to swing it out of osition.

When it is desired to shift the height of the bar 27, over which the threads are led, the operator swings the frame 30 into the position shown in dotted lines Fig. 3, Where the teeth on the lower ends of the bars 28, 29, will engage an advance tooth on the ratchet toothed cams 4:6, 47, and then swings the frame back into the position shown in full lines Fig. 3, thereby rocking the cams 46,

47, as well'as the bar 41, and thus lifting orlowering the guide bar 27 according to the positions of the cams 46, 47, relative to the bars 28, 29. Theoperator may make this change as frequently as he wishes and thus change the position of the warp threads relatively to the reeds.

The reed frame 19 as a whole, is attached to'its support '25, by means of a connecting piece 54, provided with elongated slots 55, 56, through which bolts 57, 58, set in the head piece a5, pass, thereby permitting the headpiece 54 and the frame 19 to which it is attached, to be bodily adjusted up and down. i

WVhat I claim is:

1. Ina warping machine, reeds for separating the warp threads, a guide rod in cooperative relation to the reeds and over which the warp threads pass, vertically movable andswinging supports for the guide rod and means cooperating with the swing ing supports for operating the supports and hence the guide 'rod to change the positions of the threads relative to the reeds.

2. In a warpin machine, reeds for separating the warp t reads, a guide rod in cooperative relatlon to the reeds and over which the warp threads pass after passing the reeds, vertically movable and swinging supports for the guide rod and cams in position'to engage the supports and thereby shift the guide rod to change the position of the threads relative to the reeds.

3. In a warping machine, reedsfor separating the warp threads,a guide rod in 00- operative relation to the reeds, vertically movable and swinging supports for the guide rod, ratchet toothed cams in position to engage the supports and a connection between the ratchet toothed cams for causing them to rock in unison.

4. In a warpin machine, reeds for separating the warp t reads, a guide rod in cooperative relation to the reeds and over which the Warp threads pass, vertically movable supports for the guide rod, a rocking frame in which the supports are mounted, ratchet toothed cams, one for each support, a rock shaft connecting the two cams, said shaft forming a support for the rockin frame, and means for holding the rock sha against retrograde movement.

5. In a warping machine, reeds for separating the warp threads, a guide rod in cooperative relation to the reeds and over which the warp threads pass, vertically movable supports for the guide rod, a rock shaft, ratchet toothed cams fixed to the rock shaft in position to receive thereon the said vertically movable supports, a rocking frame carrying the vertically movable supports and mounted on said rock shaft, and a pawl and ratchet for preventing a retrograde movement of the rock shaft.

6. In a warping machine, reeds for separating the warp threads, a guide rod in cooperative relation. to the reeds and over which the warp threads pass after passing the reeds, vertically movable spring-actuated swinging supports for the guide rod, and means for raising and lowering the supports at pleasure.

'7. In a warping machine, reeds for separating the warp threads, a guide rod in cooperative relation to the reeds and over which the warp threads pass, vertically movable supports for the guide rods, ,aprock shaft, a suitable support for the rock shaft, cams fixed on the rock shaft in engagement with the said vertically movable supports, a rocking frame mounted on the rock shaft and carrying the said vertically movable supports, and a spring interposed between a collar on the rock shaft and the rock shaft support for frictionally holding the rocking frame in position.

8. In a warping machine, reeds for separating the warp threads, a guide rod in cooperative relation to the reeds, vertically movable supportsfor the guide rod, a swinging frame carrying the said supports and ratchet toothed cams engaged by the movable supports and adapted to be engaged by the swinging frame.

In testimony, that I claim the foregoing as my'invention, I have signed my name in presence of two witnesses, this third day of June, 1913.
