Loon-annulus MACHINE.

Application filed August 20, 1914.

To all whom it may concern:

Be it known that I, FREDERICK S. CULVER, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Loop-Banding Machines, of which the following is a specification.

This invention relates to pertain new and useful improvements in loop banding machines, and pertains more especially to an improvement on, or attachment for, the machine forming the subject matter of the pat ent granted June 9, 1903, to F. S. Culver, NO. 730516.

The primary object of the invention is to provide means whichautomatically effects operation of the parts that are necessarily manually operated in the patent above named, which parts will be fully described and set forth in the following specification.

In the drawings, Figure l is a side'eleva tion of the machine disclosed in the aforementioned patent, showing the presentimprovement applied thereto, and Fig. 2 is an enlarged section taken on the line 22 of Fig. 1.

The same reference characters are employed in the course of the following description as are used to designate corresponding parts in the drawings of the patent in question.

The standard and the standard 6 support the driving shaft 6 the latter having a tight pulley b and loose pulley b. The belt shipper 0 is pivotally supported and has an arm 0 which depends below the bed A of the machine, which arm is held by the spring 0 against the stop 0 when the belt is on the loose pulley. The hand lever c is connected with the rocking support of the belt shipper and is used to move the belt from the loose onto the tight pulley, and in doing this the arm a of the belt shipper, which engages with the bell crank lever 0 is moved to and engages with the second notch of the bell crank lever 0 which is held in engagement by the overweight c and holds the belt on the tight pulley until the belt shipper is knocked off and the spring 0 draws the arm 0 against thestop 0 thereby moving the belt from the tight to the loose pulley.

A disk 6 is loosely sleeved upon the driving shaft 6 and provided with a grooved hub d with which hub engages the Specification of Letters Patent.

forked or bifurcated end of the lever 03. As shown and described in my patent, twister-hooks Z2 are carried by frames them selves each carried upon a shaft journaled in the standard 6 said shaft being intergeared with, and driven from the driving shaft 6 and which twister-hooks are actuated by and intergeared with said shaft. The disk I) is provided with a pin Z2 ex tending through the standard 6 and pro jecting beyond the latter so as to be engaged with and hold the frame against rotation, also as disclosed by my patent.

The lever d is pivotally supported and is provided with the arm 0Z the lower end of which engages with the notched bell crank lever (Z and is held in such engagement by the counterweight 6Z sions arm (F. The knockoff rods d and d are connected by the rod d with the block a.

The present invention consists of a vertical lever 1, pivotally connected intermediate its ends at 2 to a bracket 3,-which latter depends from the bed A, the ends of the lever being forked or bifurcated. The lower forked end of the lever 1 straddles the knock-off rod cl", while the upper end of the lever has one end of a rod 4: pivotally secured in the fork thereof, the rod being guided in a suitable bearing X to allow slidingmovement of same. The lower end of the lever 1 is adapted to abut or engage the coupling X of the knock-off rods 03 and cl, while the rod t has its free end for abutting engagement with the arm d In the patent in question, the disk 6 is necessarily thrown into operation by hand, following which the machine is started by throwing the power into action, which is the cause of considerable trouble due to carelessness on the part of the operator. In the present invention, the action is automatic in that when the rod d moves in the direction of the arrow at, the coupling X will engage with the lower end of the lever 1, thereby sliding or moving the rod 4 so that the latter replaces the arm (Z into the notch of the bell crank lever (Z thus moving the disk 6 into proper operative osition for starting of the machine. The rst twisting having been performed, the end of the rod 03 will contact with the bell crank lever (Z thus releasing the arm UP and moving the disk Z2 so as to permit the final operation of the twister head.

Having thus described my invention, I

The spring d tenclaim as new and desire to secure by Letters Patent 1 ling lever, and the knock-off rods, a horizontal sliding rod to engage the controlling lever, a vertical lever pivotally connected intermediate its ends to the machine bed and connected at its upper end to the sliding rod,;the lower end of the vertical lever being bifurcated and straddling one of the knock-off rods, and means on said knock-off rod to engage the lower end of the vertical lever;

2. In a machine of the type set forth, a rotatable twister frame, twister hooks rota table independently in said frame, means for holding the frame from rotating, means for throwingsaid holding means into operative position, a knock-off rod, a sliding rod to operate the throwing means, and connections whereby said shdlng rod is; operated by the knock-off rod.

3. In a machine of the type set forth, in

combination with a; rotatable twister frame,

rotatable twister hooks rotatable independently in said frame, means for holding the frame from rotating, means for throwing said holding means into operative position, a knock-off rod, and means whereby upon actuation of the knock-off rod said throwing means will be automatically moved to throw the twister hooks into operative posi tion.

4. In combination with a rotatable twister frame, twister hooks rotatable independentlyin said frame, means for holding the frame from rotating, means for throwing said holding means into operative position, sliding means to engage and actuate said throwing means, a knock-off rodfand a pivoted means connected to said sliding means and engaged with the rod whereby upon movement of the rod the pivoted means will be actuated to thereby actuate the sliding means so as. to automatically move the throwing means into operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FREDERICK SLOCUM CULVER.
