MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 481,409, dated August 23, 1892.

Application filed December 30, 1891. Serial No. 16,520. (No model.)

To all whom, it may concern.-

Be it known that I, FELIX MENY, of'Elizabeth, in the county of Union and State of New Jersey, have invented a new and Improved Mechanical Movement, of which the following is a full, clear, and exact description.

Theinvention relates to devices for convert ing reciprocating motion into rotary motion.

The object of the invention is to provide a new and improved mechanical movement ar ranged to transmit the power uniformly and without undue loss, dead-center positions being completely avoided.

The invention consists of two rock-shafts controlled from a reciprocating cross-head and provided with slotted arms or drivers, of which one delivers the crank-pin to the other to carry it around one-half revolution.

The invention further consists of a reciprocating cross-head provided with pivoted wings engaging the crank-arms of the rock-shafts and adapted to be locked in place.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 isa sectional plan view of the improvement on the line 1 1 of Fig. 2. Fig. 2 is a sectional side elevation of the same on the line 2 2 of Fig. 1. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2. Fig. 4 is a similar view of the same on the line 4 4 of Fig. 2. Fig. 5 is a like view of the same on the line 5 5 of Fig. 2. Fig. 6 is an end elevation of the same. Fig. 7 is a transverse section of the same on the line 7 7 of Fig. 2, and Fig.8 is a similar view of part of the same on the line 8 8 of Fig. 2.

The improved mechanical movement is mounted on a suitably-constructed base A, supporting the guideways B, in which is mounted to slide vertically the cross-head 0, connected in the usual manner with the machine the reciprocating motion of which is to be converted into rotary motion. On the front face of the cross-head O are pivoted the sets of wings D D and D D, each set having a common pivot and the two sets having between themselves grooves for the passage of the wrist-pins E and E, secured on the crankarms F and F, respectively fastened on the shafts G and G, respectively mounted to rock in suitable bearings arranged on the base A.

The wrist-pin E is arranged between the two wings D and D and the other wrist-pin E is arranged and operates between the two wings D and D The forward ends of the rock-shafts G and G carry arms or drivers H and II, respectively provided with slots H and H respectively engaging the wrist-pin I, held on the main crank-arm I, attached to the shaft J, the rotary motion of which is to be transmitted to other machines.

The wings D, D, D and D are mounted to swing, so as to release the wrist-pins E and E at the proper time, as hereinafter more fully described, and the said wings are also adapted to be locked in place by blocks K, K, K and K respectively mounted to slide transversely on the front face of the crosshead 0, the blocks K and K being arranged above thewings D D and the other blocks K K being arranged below the wings D and D respectively.

The blocks K, K, K and K are provided with pins L, L, L and L respectively extending rearward through transverse slots O, formed in the cross-head C, the rear ends of the said pins engaging cam-grooves N,N, N and N respectively arranged in one face of a cam-plate O, secured on a short shaft 0, mounted to turn in suitable bearings arranged on the base A. From the rear face of the camplate 0 extends a wrist-pin O engaging a slot P in a crank-arm P, fastened on a shaft Q, extending longitudinally and mounted in suitable bearings on the under side of the base A.

On the front end of the shaft Q is secured an arm R, provided with a pin R, traveling in a cam-groove S of a cam S, held loosely on the driven shaft- J and'attaehed to a disk T, rigidly secured on the said driven shaft J. The disk T is provided with a segmental slot T through which passes a screw T, screwing in the cam S, so as to fasten the latter on the disk T, and thus to the shaft J, the said cam, however, being adjusted to properly set the cam relative to the pin R of the arm R.

The slots H and H of the driving-arms H left downward and back again, while the other arm H has a swinging motion from left to right downward and back again, similar to the movement of the crank-armsF and F.

The cam-plate O for controlling the movement of the locking-blocks K, K, K and K is arrangedin such a manner that the blocks are shifted transversely to close on the wristpins E and E, respectively, at the proper time, the cam-grooves N, N, N and N be ing arranged correspondingly-that is, the

' rooves N and N diver in from the ivot b b D of the plate 0 upward and outward,while the other two grooves N and N converge from the middle downward, as is plainly shown in Fig. 4. When the cross-head C is at the beginning of its downward stroke, the drivingarms H and H stand with their grooves H and H respectively, in a right-angular position over the wrist-pin I, and at this time the wings D and D are closed by the blocks K and K respectively, while the other wing D i is unlocked by its respective block K, as shown in Fig. 3. The downward movement of the head C now exerts a pressure on the said wrist-pin E to move the crank-arm F, and consequently the driving-arm H, in a downward direction, so that the driving-arm H drives the wrist-pin I forward in the direction of the arrow a. (See Fig. 7.) As the wrist-pin I is still in engagement with the radial slot H of the driver H, the latter is caused to swing upward a short distance, causing a like upward movement of the crank-arm F and its wrist-pin E, the upward movement of the latter being free on account of the wing D being unlocked by the block K. The upward movement of the wing D permits the crank-arm F and the driving-arm H to swing into an angular position of about fifty-two degrees, and then the wrist-pin E again comes in contact with the wing D and by the downward movement of the cross-head is caused to swing downward, causing a similar move ment of the driving-arm H, as previously explained. The wrist-pin I travels in the enlarged opening H of the driving-armH during the time the said wrist-pin is carried around one-half revolution by the arm H, and on the return strokeof thewrist-pinit travels through theenlargedopening H of the arm H at the time the wrist-pin is carried upward in the slot H of the driving-arm H. It will be seen that by this downward movement of the cross-head O the two arms H and H swing downward in opposite directions, so that their radial slots H and H about meet when the crank-pin I assumes a lowermost position, it being, however, understood that the arm H leads somewhat, as (in ring the downward movement the position of the lockingblocks is shiftedthat is, the locking-block K moves inward to close the wing D, while the block K shifts outward and unlocks the wing D forthe w crank-arm F to permit the wrist-pin E to i assume a position somewhat lower than the wrist-pin E can mission of the wrist-pin I from the slot H of the arm 11 to the slot H of the arm H thus takes place before the cross-head and the wrist pin I assume a lowermost position.

possibly attain. The trans Thus on the return stroke of the cross-head the wrist-pin I is fully under the control in the slot H of the driving-arm H, and the driving-arm H is free to swing farther downward to assume an angular position of about fifty-two degrees, thus forming no obstruction to the wrist-pin and permitting the same to readily leave the slot H to travel in the opening H duringthe upstroke of the cross head and the wrist-pin E. It will be-seen that by this construction dead-center positions are completely avoided, so that the power. is nni- L formly transmitted and withoutundueloss,except theusual loss by friction in the several parts. It is further understood that when the driving-arm H moves the crank-arm I onthe downstroke of the cross-head O and has passed about one-half the downstroke then the wing D commences to close on the wrist-pin E, while the other wing D is unlocked by the block K so as to permit the wrist-pin E to gain on the other'wrist-pin E, held solidly in the groove between the two locked wings D and D In a like manner on the upward movement of the cross-head C the wing D is unlocked by the block K at about the time one-half of the upstroke is made, so that the wrist-pin E can gain on the wrist-pin E to bring the arm H into proper position at the time the cross-head O isat the end of its upstroke and the downstroke begins, as previously described. It is understood that this opening and closing of the wings D, D, D and D in the order named is accomplished by the shifting of the cam-plate 0, controlled from the driven shaft J by means of the cam S, the arm R, the shaft Q,:and the crank-arm P, pivotally connected with the said plate 0.

Having thus described my invention, I
