Patented Dec. 8, 1931 PATET oFricE HENRY W. HONEYMAN, JR OF PROVIDENCE, RHODE ISLAND WARP LOOPING MACHINE Application filed April 22,

This invention relates to means for automatically hanging loops or folds of traveling warp over a support; and the object of this invention is to provide a machine to which a continuous sliver or warp is fed, the machine being provided with a reciprocating warp conducting member arranged to swing back and forth to deposit or hang the warp in folds or loops on a bar or supporting member to be subsequently transferred on this supporting member for further treatment.

A further object of the invention is the provision of traversing means for advancing the warp guiding member laterally, causing the warp folds to lie side by side along its receiving bar.

vA still further object of the invention is to provide aset of elongated feed rolls and providing a warp-receiving bar of a length substantially that of the rolls over which the warp is laid or hung in folds or loops, the warp guide memberbeing advanced along said feed rolls to lay the warp strands side by side along the length of the bar.

WVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a front elevation of the machine.

Fig. 2 is an end elevation showing a portion of the frame removed.

35 Fig. 3 is a diagrammatic viewshowing the means for driving the different elements of the machine.

Fig. 4 is a diagrammatic view showing a portion of the machine in perspective, and illustrating the general arrangement of parts and the operation of the machine.

Fig. 5 is an enlarged sectional view of the traversing screw shaft with its engaging lead pawl mounted in its nut.

Ordinarily in drying and'otherwis'e treat ing textile warps it is first hung by hand in folds over a bar and then the loaded bar-is 1930. Serial No. 446,230.

removed to present the warp for further treatment and another bar positioned to rece1 ve the next load, but my improved ma chlne serves to automatically hang or lay the warp over the continuously running bar automaticaly during the operation of the machine; and to accomplish this automatic operation in a simple and effective way, I have provided a machine to which the continuous sliver or warp is fed, the machine being heren illustrated as having a pair of reciprocatlng rolls arranged to swing back and forth over the warp receiving bar to lay or hang the warp 1n folds or loops thereover, the bar being supported for ready removal together with the warp hung thereon for further treating the warp; and the following is a detailed description of the present embodiment of my invention and showing the preferred construction of machine by which these advantageous results may be accomplished:

With reference to the drawings, 10 designates the framework of the machine on which 1s rotatably mounted an elongated upper feed roll 11 and a similar cooperating lower feed roll 12 to which the warp 13 is fed over the guide roll let and thru the traversing guide eye 15, the warp being led from these feed rolls down thru the oscillating fold laying rolls '16 and 17 which swing to hang the warp upon the bar 18 supported below.

These

rolls

16 and 17 are supported in bearings in the swinging arms 19 at either end of the machine, roll 17 being pressed thru action of the spring 20 to pinch the traveling warp against its companion roll 16, which latter roll is rotated from pulley 21 on the roll 12 thru belt 22 to assist in feeding the warp.

This arm 19 is hung on the roll shaft 23 and is caused to oscillate by rotation of the crank disc 24 thru connecting rod 25 which is pivoted at 26 to the disc and at 27 to the oscillating arm 19. V

In order to cause the warp to advance lengthwise along the elongated feed rolls and have its folds 36 lie side by side along the bar 18 supported on arms 33 beneath the same, I have provided a traversing screw 28 to which the warp guide eye 15 is connected. This traverse screw has the usual pawl 29 mounted in the nut 30 mounted thereon, to enter the helical groove 31 in the screw and as the screw is rotated the pawl follows the screw and causes the nut and guide eye 20 to advance along the feed rolls and upon arriving at the end of the screw the pawl is caused to follow the groove over into the return groove as best illustrated in Fig. 6, to automatically reverse its direction of travel at either end of the screw, which continues to run in the same direction.

In order to prevent this nut 30 from rotating on its screw 28, I have provided a guide arm 32 which engages and slides along the guide rod 35.

The machine is driven from the main roll shaft 23 thru clutch pulley 34 and motion is transmitted from this shaft thru sprocket chain 37 to the traverse screw 28 and thru sprocket chain 38 to the crank discs 24.

My improved warp-folding machine is very simple and practical in construction and efiective in its operation and by its use the warp may be automatically hung in folds along the length of the bar, which bar may be readily removed with the warp thereon into any desired position for subsequent treat ment of the warp.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the devioe'is susceptible, the invention being defined and limited only by the terms of the appended claims.
