CRANK FOR MACHINERY.
SPECIFICATION forming part of Letters Patent No. 397,367, dated February 5, 1889.
Application filed November l, 1888. Serial No` 289,705. (No model.)
To all whom, t may concern:
Be it known that IVILLIAM lA-I. KAYE, a citizen of the United States, and a resident of IVenonah, Gloucester county, New Jersey, have invented an Improved Crank for Machinery, of which the following is a specilication.
rlhe object of my invention is to so construct a crank 'for machinery that there will be no dead-center point, as in the usual crank; and this object I attain in the manner hereinafter set forth, reference boing had to the accompanying drawings, in Which- Figure l. is a perspective view of a crank tor machinery constructed in accordance with my invention. Fig. 2 is a i'ace View ot' the same, and Fig. is a similar view showing the crank-pin in a different position from that shown in Fig.
A is the crank-arm, having the usual opening, ci, for the reception of the crank-shaft.
Instead of connecting the crank-pin l; directly to the crank-arm, however, as usual, I connect said crank-pin to a block, IS, the pivot rl of which is offset in respect to a line drawn through the center of the crank-shaft opening and through the center of the cranlepin.
The block I3 is contained within a reeess,f, in the face of the crank, this recess terminating in shoulders g g, and between the block B and the shoulder g isinterposed a spring, 71, the opposite ends of which are preferably let into sockets or recesses in the block and shoulder, as shown in Figs. 2 and The tendency of this spring is to maintain the block I3 in its normal position-that is to say,with one `face of the block in contact with the shoulder g, as shown in Fig. 2-the spring being such that it will not be compressed when the only obstacle to the movement ot the crank is the load due to the work. X' ielding ot' the block B in the direction of the arrow, Fig. 2, however, is permitted when there is more than the normal resistance to the movement of the crank-arm.
It Will be seen that owing to the offset-ting of the pivot ol' the block B `in respect to aline drawn through the centers of the crank-shaft and crank-pin there can never be any deadcenter point in the movement of the crank, for if the crank-pin occupies such relation to the crank-shaft that the line of pull is directly through the center of the crank-shaft, as shown in Fig. 2, the crank-pin will, owing to the offset pivot of the block B, be at liberty to move independently7 of the crank, so as to shift the line of pull, as shown in Fig. 3, and thus cause the crank to turn.
Although it is preferred to use a springinterliosed between the pivoted block and a bearing on the crank-arm, other means may be employed :for retaining the block in its normal position, ii desired. For instance, a spring coiled around the pivot of the block and cmgaging with the block and cra'tnk-arm, as shown by dotted lines in Fig. il, maybe employed.
I Iavin g thus described my invention, I claim and desire to secure by Letters Patentl. lhe combination of the crank, the crank pin carried by a block pivoted to the crank at a point ollset in respect to a line between the centers ot the crankshaft opening and crank-pin, and a spring acting upon the block to preserve it in its normal position, all substantially as speciied.
2. The combination of the cranlearm, the crank-pin carried by a block pivoted to the crank-arnl at a point otlset in respectto aline between the centers of the crank-shaft opening and crank-pin, and a spring interposed between said pivoted block and a bearing on the crank-arm, all substantially as speci fied.
23. The combination of the crank-arm having a .recessed face, a block carrying the crank-pin and pivoted in said recess at a point offset in respect to a line between, the centers of the crank-shaft opening` and crankpin, and a spring interposed between said block and a shoulder on the clank-arm, all substantially as specified.
In testimony whereof I have signed my name to this speci ii cation in the presence of two sub scribing witnesses. v
