DEVICE FOR CONVERTING MOTION.
SPECIFICATION forming part of Letters Patent No. 310,169,- dated January 6, 1885.
A pplication filed November 3, 1884. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM H. ATKINSON, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Means for ConvertingMotion, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention consists in the combination, with a pair of duplicate multiform drivers and means for rotating the same in unison, of a sliding head and bearers acted upon by said drivers, whereby a reciprocating movement is imparted to said head.
The embodiment of the inventionshown herein is illustrated in Figure l by a front elevation, in Fig. 2 by a plan or top view, and in Fig. 3 by a horizontal section on the line at of Fig. 1.
The moving parts are sustained in a bearer, A, that is fixed in a stationary position. In a guide way or ways out or otherwise provided in this bearer a head, B, is arranged to slide, said head being slotted, as at C, with an elongated opening adapted to admit the passage through the head of the shaft of the drivers and to admit the range of reciprocation required by said head in its reciprocations. The drivers D E are mounted upon shafts 24, having the bearings in the bearer A, (which may be extended by bosses F G,) and these shafts, in addition to having the drivers D E securely fastened to them, carry at their opposite ends meshing toothed wheels H I, one of which is driven to impart the primary motion. The drivers D E are multiform-that is, are manysidedand hence present a number of cam projections, 5, and corresponding depressions, 6. These cam projections engage the bearers M N, (which might be studs or rollers) suitably fixed to the face of the head B, and thus propel the same. The two drivers are duplicates, and in the example shown their cam projections 5 are four in number, and their corresponding non-operative surfaces 6 are likewise fourin number. IVhen propelled by the rotation of their shafts, these drivers rotate in opposite directions, and while the cam projection 5 of one, as D, is acting upon the bearer, as M, of the head B to move the same in one direction the depressed part 6 of the other driver, E, is so presented to the bearer N of said head 13 as to permit such movement. As said cam projection 5 completes its throw and passes the bearer M the corresponding cam projection, 5, of the driver E engages the bearer N and moves the head B in the opposite direction, the depressed part 6 of the driver D properly presenting itself to the bearer M to permit such movement. Thus a reciprocation of the head Bis eifected by a positive movement, and the rotation of one part is con verted into a reciprocatory movement in another part of the mechanism. The reciproeations thus effected during each rotation of the driving-shaft are equal to the number of cam projections on the drivers-that is to say, with four cam projections, 5, four reciprocations of the sliding head B will be accomplished.
The multiform drivers D E may be given a shape that will provide three, five, or any other convenient number of cam projections, 5, between which co-operating depressions 6 will be provided, and since these depressions must vary more or less from a straight line, according to the throw desired, they may be straight, as shown, or be curved to the extent required. Of course, as their depression is increased the projection of the cam 5 must be increased, that a harmony of action may ensue and a steady movement of reciprocation of the sliding head be attained. Thus the shape of the duplicate drivers will always be such that no matter how much one must project into the other the distance on a line extending from their extreme edges and passing through their axes will be the same in whatever rotary position they may stand.
Although shown as pretty nearly in contact, the drivers might be set a distance apart, if proper gearing for rotating them in unison and in proper direction is provided.
This mechanical movement is well adapted for punching-machines for actuating the reciprocating punchheads, in sewing-machines for producing the movement of the recipro eating needle-bar, and in any machine where it is required to produce a reciprocating movement from a rotary one-such, for instance, as a can-seaming machine, as illustrated in my application filed August 24, 1884, wherein the drivers D E may become the head-stocks supporting seaming-anvils, with which seamingtools supported by the sliding head 13 will corying bearers that are acted upon by said operate and be properly, though positively, drivers, whereby a reciprocating movement is moved to accurately conform in position with imparted to said head all substantially as dethe constantly-changing path of travel the scribed.
