SPECIFICATION forming part of Letters Patent No. 606,301, dateafmne es, 1898.

Application filed June 1,1897. Serial No. 638,999. (No mdel.)

To @ZZ whom, it. may concern:

Be it known that I, SIMON Ross, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Shoe-Upper Turning and Beading Machines, of .which the following is a specification.

My invention relates to that class of shoeupper turning and beading machines shown in Letters Patent of the United States No. 432,902, granted July 22, 1890.

The object of the present invention is to simplify the driving apparatus and make the same more durable.

Another object of my invention is to provide means for controlling the movement of the turning-iron and to adjust the driving mechanism for the same to ixed positions or to control the same by treadle movement, as desired.

The various features of my invention are more fully set forth in the description of the accompanying drawings, making a part of this speciiication, in which- Figure l is a front elevation of myimprovement. Fig. 2 is a longitudinal and vertical sect-ion of my improvement, showing the driv ing mechanism in elevation. Fig. 3 is a section on line an, Fig.2. Fig. 4 is a section on line y y, Fig. 2.V

A represents the base on which the shellframe B rests. "C represents the stationary jaw, and D the movable jaw, of the beader. E represents the hollow standard in which the turning-iron reciprocates. F represents the main shaft, and G the sleeve in which the same journals. These parts are substantially the same as shown in my said former patent.

The driving mechanism of myimprovement is constructed as follows:

fr represents a crank or wrist to shaft F.

CZ represents a connecting-rod j ournaled on crankepin a and to the ear c of the yielding arm f, which is loosely hinged to the movable pin attached b represents an extension of the connecting rod d, carrying a secondary wrist-pin c. In order to cushion the movement of said jaw D, which is oscillated on its pivot D by conanism: h represents a coil-spring interposed between armfand the outer end of the jaw D.

t' represents a rubber spring between the horizontal portion of jaw D and the tightening-bolt g.

I represents simply a washer between the nut and cushion z'. This cushions the downward movement of arm f and the outward movement of jaw D, while spring h cushions the stroke of said ljaw D against the material held between it and the stationary jaw C.

j represents a nut for regulating the tension of the coil-spring h. Thus I obtain a noiseless movement of jaw D and its drivin g'mechanism, as Well as cushioning its movement 'at each end of the stroke.

The turning-iron is driven in unison with the beading-j aw by the following mechanism: To the supplemental wrist-pin c is pivoted a link 7c, the other end of which is pivoted to the rock-arm Z, which oscillates on the center Z'.

H represents the turning-iron, reciprocating vertically in guides of the standard E, the lower end of which is pivoted upon the center m of rock-arm Z. protuberance of the turning-iron I-I beyond the guides n, between which it reciprocates, I pivot the rock-arm Z in the following manner:

K represents an oscillating arm loosely hinged at one end to the frame ofthe machine by the center-bolt o, which is connected to the head VOby a pivot o. The end of said arm is made convex and engages in a concave seat formed in the frame and facts as the cen ter on which said arm K rocks, the pivot-bolt o serving to hold said arm firmly to its seat.

In order to take up lost motion and to pre vent rattling and jar, I provide a spring washer p, interposed'between the set-nut q and the frame. I thus secure a noiseless movement of said arm K. Rock-arm Zisconnected to this arm by means of a link r, pivoted thereto, as shown in Fig. 2. Arm K is provided with a shaft L, which projects out- Ward through the segmental slot M in the side of the base-frame. This shaft journals in gral with the arm Ki" R represents 'aset-nut tapping on said shaft L. Vhen said nut R is slackened, the shaft L is free to move up necting-rod CZ, I provide the following 1nechand down in the slot M. Zhen moved d0wnthe sleeve P and in the hub P', formed intef In order to regulate the- Ward, it depresses the arm K and lowers the journal of the turning-iron H by lowering the center on Which rock-arm Z journals. The link r, turning on its center, accommodates itself to the new position. By means of the shaft L and set-nut R the position of arm K can be secured at any desired fixed point; but in case it is desired to have the movement of the turning-iron under the control of a treadle, so that the operator can cause the turning-iron to protrude more or less at will, the set-nut is slackened and the treadle S applied by connecting rod S to the ear s of sleeve P.

By means of the combination of Wrist-pin 'c with the crank-pin a the driving mechanism is simplified and operates the turning-iron and beader-jaws with much less number of parts and less friction and more positively than in the device of my said former patent. l amalso enabled to control the stroke of the turning-iron either by lixed adjustment or by the treadle movement, as desired. This method of construction is much superior to my said former invention in point of durability, Which is the most important consideration in machinesof this class on account of the high rate of speed at Which they are driven.

Having described my invention, I claim- 1. In a shoe turning and beading machine, in combination With the oscillating beaderj aw, a plate loosely hinged to the arm thereof,

driving mechanism, a rod connecting said plate With the driving mechanis1n,and springs interposed between the Working parts of said plate and jaw to cushion the movement ofthe latter, substantially as described.

2. ln a shoe turning and beading machine, mechanism for reciprocating the turning-iron comprising a verticallyadjustable movable 4E. ln a shoe turning and beading machinev the combination of a stationary and an oscillating header-jaw, driving mechanism connected to the oscillating j aw, lever mechanism connecting said driving mechanism to the turning-iron, said lever mechanism being mounted upon a vertically-adjustable arm whereby the stroke of the turning-iron is controlled, substantially as specified.

5. In a shoe turning and beading machine the combination With the main shaft, of a connecting-rod pivoted thereto, and to a yielding arm for driving the oscillating beader-jaw, a rock-arm connected at one end by means of a link to the driving mechanism and at the other end to the turning-iron, said rock-arm being pivoted at a point between its ends to a vertically-adjustable arm movably secured to the frame of the machine, substantially as specified.

In testimony whereof l have hereunto set my hand.

SIMON ROSS.
