W'INDER-BALANCING MECHANISM.

Application filed August 18, 1921.

To all whom it may concern:

Be it knownthat I, HARVEY L. YOUNG, a citizen, of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful iVinder-Balancing Mechanism, of which the following is a specification.

This invention relates to machines for winding a wire, a cord or a strip onto or into a str cture such as a cabled wire ring or gromet, a rope, a cloth or paper wrapping for a tire, etc., and its object is to provide means, preferably automatic in its action, for variably counterbalancing the weight 01 the reel of wire, cord or the like during the revolution of said reel about the work, in order to compensate for the diminishing weight of the coil of wire or other material on the reel as said material is used up in the work. The result is longer life and greater speed for the machine and greater safety in its operation.

Of the accompanying drawings, Fig. 1 is a front elevation, partly broken away and in section, of portions of a winding machine equipped with a preferred form of my invention.

Fig. 2, is a section on the line 2-2 01 Fig. 1. p

Fig. 3 is a section on the line 33 oi- Fig. 2.

Fig. 4 is a sectional view on the line 4.4t of Fig. 3 showing the screw-rotating ratchet and pawls, in their operative relation, to gether with the pawl-lifting means and li'fter retaining latch.

Fig. 5 is a sectional view on the line 5-4) of Fig. 3, but showing these parts after the. pawls have been tripped to render the weight-feeding screw inoperative.

In the drawings, is a part of the machine frame and 11 is a stationary, hollow, annular guide or trough adaptedto receive the work, which in this instance is a wire gromet for a tire bead. 12 is a stationary bearing in the form of the major segment of an annulus mounted upon the frame 10 and rotatably supporting the winder ring 13, which is interrupted by a slot at 14-, for pass ing the finished work transversely out of the -machine. This ringis rotated by suitable gearing (not shown) and on one side has bolted theretoa forked holder 15 which carriesa reel'lG for a coil of wire 17, forming whose nose portions 42 engage the Serial No. 493,257.

the material of which the gromet is made, the reel being loosely journaled on a spindle 18 and having a tension mechanism cdnsist- 111g of a brake including the adjusting screws 19. The wire passes from the reel around a guide roller at 20 and between two pairs of grooved feed-rollers 21, 22 which force it through a spiral passage in a bending the 23, so that the wire may be spiralled onto a core strand of wire in the gromet so as to lie properly in place thereon without. tending to unwind.

Through suitable gearing on the back of the machine (not shown). power is transmitted to a bevel gear 24 on the end of a sleeve journaled within the winder-ring 13, and said gear is driven ahead at a predetermined rate faster than the angular speed of the winder-ring. The gear 24 meshes with a mating bevel-gear 25, loosely mounted on a shaft carried by a multiple bearingbracket 26 on the opposite side of the winder-ring from the reel 16.

Fixed to the back of the bevel-gear is a spurgear 27 meshing with another spurgear 28 attached to a shaft 29, which atone end drives the wire-feeding rollers 21, 22 through suitable gearing 30. On the opposite end of the shaft J) is eccentrically mounted a crank-pin 31 (Fig. 2), to whch is pivoted a drag-pawl 32, whose hooked end engages the teeth of a ratchet wheel 33 which is held from reverse rotation by a checkpawl 34:, this ratchet wheel having a camstud 35 projecting outwardly therefrom and engaging an arm 36 formed on a pawl-carrier 37, which oscillates freely about the axis of a shaft 38, whose inner end is fixed in the bearing-bracket 26. A spring 39 draws the pawl-carrier in a direction opposite to the movement imparted by the stud 0n av stud 4-0, mounted on the pawl-carrier 37, is pivoted a set of three feed-pawls -11. I teeth of a ratchet wheel 13, secured to the inner end of a hollow screw 44, which latter is mounted to turn upon the fixed shaft 38 and has a squared portion at its outer end for receiving a crank tool to turn the screw by hand when desired. The pawls 41 are backed by springs 4:19, and the front or driving faces and under or lifting faces of the pawl noses 42 are relatively stepped so that the possible lost motion in a forward feedvolve about the work, a counterbalancing weight on the opposite side of the axis of revolution trom said reel, an auxiliary weight adjustable toward and from said axis on the same side as the reel, and means operable during the rotation of the winder for adjusting said auxiliary weight away from said axis.

l. In a winding mechanism, the combination of a winder having a reel holder adapted to revolve about the work for withdrawing material from said reel, a shiftable weight for controlling the position of the center of gravity, and means actuated by said material'withdrawing means for auto matically moving said weight relatively to the axis of revolution as the winder rotates.

In a winding mechanism, the combination of a winder having means on one side of its axis of revolution for feeding material into the work, a counter-balancing member on the opposite side of said axis, a nut and a screw for moving said member from and toward said axis, and means actuated by said material-feeding means for rotating oneof said nut and screw.

6. In a machine for making wire gromets, the combination of a gromet support, a winder-ring encircling the same and provided with a wire reel on one side of its axis oi revolution, means on said Winder-ring for withdrawing wire. from said reel, a counterbalancing member on the opposite side of said axis and means actuated h said wire-withdrawing means for automatirally feeding said memberinwardly towards said axis.

7. In a winding mechanism, the combination oi a rotary winder having a source of material supply on one Side of its axis of revolution, a shittable weight controlling the position of. the center of gravity, means for automatically moving said weight relatively to said as the material is used up in the work, and means timed with the movement of said wei ht for automatically disabling the weight-moving means at the limit of movement of said weight.

8. In a winding mechanism, the combination of a rotary winder having areel on one side of its axis of revolution and a counterbalancing member on the opposite side, feeding means adapted to be actuated during the rotation oi said winder for imparting stepby step movement to said member toward the axis of revolution, and means timed with the movement of said counterbalancing member for throwing said feeding means out of action. i

9. In a winding mechanism,- the combination of a winder having a reel holder on one side oi its axis of revolution, a shiftable weight controlling the position of the center of gravity, aniit connected with said weight, a screw carried by the winder and engaging said nut, and means adapted to be actuated during the rotation of said winder for turning said screw, the last said means including a pawl and ratchet mechanism carried on said winder.

10. In a winding mechanism, the combination of a rotary winder having a reel holder on one side of its axis of revolution, a shiftable weight controlling the position of the center of gravity, and means for imparting a movement to said weight relatively to said axis, said means including a ratchet wheel controlling the position of the weight, a pawl adapted to be reciprocated during the rotation of the winder, a pawllifter reciprocating with the pawl, and a tripping device movable with the weight and brought at the limit off its travel into the path of a part on said lifter for automatically retracting the pawl.

11. In a winding mechanism, the combination of a rotary winder having a reel on one side of its axis of revolution, a counterbalancing yoke on the opposite side of said axis, a nut on said yoke, a screw on the winder engaging said nut and means on the winder for guiding the ends of said yoke in a direction transverse to said axis.
