SPOOL-CARRIER FOR BRAIDING, LACE-MAKING, AND LIKE MACHINES.

Specification of Letters Patent.

Patented Aug. 3, 1M5.

Application filed June .30, 1913, Serial No. 776,613. Renewed January 5, 1915. Serial No. 669.

To all whom it may concern:

Be it known that I, Eorrnno Sorr AoH'rL, a subject of the Emperor of'AustriaeHungary, and resident at Ober-lValtersdorf, Austria-Hungary, have invented certain new and useful Improvements in or Relating to Spool-Carriers for Braiding, LacerMaking, and like Machines.

The invention has reference to improvements in or relating to spool-carriers for braiding, lace-making and like machinesand it consists in a spool carrier the characteristic feature of which, as compared with the known carriers, is that the horizontal spool spindle is carried by a slide which is guidedso, that it can move up and down upon the bobbin stand and which acts as a weight upon the spool to produce the neces sary tension on the thread.

I have illustrated my invention in the accompanying drawing in which,

Figure 1 shows my improved spool carrier in side elevation and partly in section, and Fig. 2 is a plan view of Fig. 1'.

The table or carriage (not shown) of the braiding or like machine engages in the space 1 between the supporting flanges 2, and the upper flange 2 carries the bobbin stand consisting of two vertical bars 3 and 4. A slide 5 which carries a horizontal spindle 6 on which the spool is placed is mounted slidably upon the bar 3, and one of the flanges 7 of the spool is formed with ratchet teeth. A pawl 9 which is pivotally mounted on the slide 5 is pressed by a spring 10 toward the teeth in the flange 7 and is constantly engaged in a verticalslot 11 in the shorter bar 4- The space between the top of the bar 4 and the thread guide 12 at the upper end of the bobbin stand is left free for the purpose of enabling the spool 8 to be readily removed from the spindle 6 and a fresh spool to be placed in position when the spool carrier is raised. The thread guide arm 14 is curved, about as shown in the drawing, so that it lies at one side of the path of the slide 5, so that the upper end of the slide can project through the opening formed by the bend 15. Due to this arrangement the slide 5 can be readily removed from the rail 3 when the spool 8 is removed from its spindle 6 and the pawl or lever 9 is disengaged from the slit 11.

A further feature of the invention consists in that the slide 5 has a projection 16 which extends into the path of the lever 9 and limits the downward movement of the said lever. The lengthening or shortening of the thread which takes place during the working of the machine is compensated for by the slide 5 moving downward or upward upon the rail 3, so that the tension on the thread always remains the same. A. subsequent delivery of the thread is permitted, when the spool 8 is raised suiiiciently far together with the slide 5 and the hinge of the lever 9, when the free end of the latter is brought into contact with the upper edge of the slot 11, whereupon the toothed flange 7 is released from the said lever and the spool rotates one tooth farther, allowing a corresponding length of the thread 13 to be drawn ofl", this procedure being repeated as soon as the thread given oil has been worked into the fabric which is being produced or operated on.

When a number of spools are employed and a single thread breaks, the other threads may easily become entangled and prevented from running off the spool. Thereby the spool would, correspondingly to the working-in of the threads, be raised farther and the result would be that defective work might be produced if the extent of movement of the spool were not limited by the stop 16, as shown in the drawing, so that all the threads break without fail at the right moment, whereupon the slide 5 falls down and its laterally projecting pin 17 then brings about in the known manner the automatic stopping of the machine. The weighting of the thread or the necessary tension on same may be varied, for example, by hanging suitable weights on the slide 5. Such weights are preferably adapted to slide upon the rail 3 and to engage the said rail similarly to the slide 5.

I claim:

1. In a spool carrier, the combination with a spool having a ratchet, of a vertical bobbin stand therefor, a spindle for said spool, a

plate secured to said spindle, ears on said plate adapted to engage the bobbin stand whereby the spool will be slidably mounted thereon to produce the necessary thread tension by the weight of the spool, and a. pawl on the bobbin stand to engage the ratchet on the spool.

2. In a spool carrier, the combination with a spool supporting member, of a spool mounted thereon, said spool having a ratchet, a relatively shorter member oppofor the insertion or removal ofthe spool,

and a pawl mounted on the spool supporting member to engage the ratchet, said pawl being limited in its movement in one direction by the shorter memben. v

3. In a spool carrier, the combination with an upright, of a member slidably mounted thereon, a spool on said slidable member, a thread guide on said upright, an arm extending rearwardly from the upright and reversely curved to permit the removal of the slidable member from the upright, and means mounted on the slide to engage the spool when the latter is lowered by the slide.

4. In a spool carrier, the combination With a slidably mountedspool having a ratchet, of means for limiting the upward movement 20 of said spool, said means comprising a slide, a shoulder on said slide, a pivoted member on the said shoulder to engage the ratchet,

' an upright provided with a slot adapted to be engaged by said pivoted member, a 25 spring bearing on said member to force the same into the slot, and means for pivotally mounting said spring.

- In testimony whereof I have set hereunto my hand in presence of two witnesses. I
