UNITED STATES PATENT OFFICE.
EMANUEL RAU, oE NEW YORK, N. Y., AssieNoR To THE EMANUEL RAU MANUFACTURING COMPANY, or SAME PLACE.
'M EoHANloAL MOVEMENT.
SPECIFICATION forming part ef Lettere Patent No. 413,791, dated october 29, 1889.
Application tiled July 15, 1889.
cam mechanism by means of which the cam gives one reciprocation to the rod which car- 4 ries the carn-ro1l to two revolutions of the cam understand, construct, and use my invention,
. vibrating rod D the whole Weight of the pitl man and other parts is supported by cam-roll I will proceed to describe it, referring to t-he drawings, in Which- Figure l represents a side elevation of my invention, and Fig. 2 represents an end view with the cam-shaft in section.
A is the cam-shaft.
B is the cam.
O is thecam-roll.
D is the vibrating rod or bar, which carries the cam-roll in bearings E.
F is a pitman-rod constructed at its lower end with a fork to straddle the cam-shaft, and at its upper end takes hold of a crank; pin G in-a crank H, which is keyed to another shaft I.
A little distance above the cam-shaft, on
pitman F, a lug J projects, and on its under side is a recess K, into which the upper end of the vibrating rod D takes. Through this Serial No. 317,630. (No model.)
lC on cam B, and within its cam-groove L M vare pins or studs in pitman F, to guide the vibrating rod D sidewise. The camB is composed of two portions of different sizes diametrieally-the part N and the part O--but their diameters coincide practically at one point. The cam-groove traverses the two portions spirally, or cross tracks at this point, so that the cam-roll guided by the cam-groove traverses from the portion Nto the portion O,
. and one revolution of the cam-shaft A carries the cam-roll C around the portion O and the next revolution carries it around the portion N In passing from N to O the cam-roll C and the rod D move away from a vertical lino. The rod D, bein gloosely fulcrumed in the recess K of the lug J, is free to vibrate and allow motion to the cameroll C in its circuitous travel around the two portions of the cam B. The pins M guide the rod D and prevent side motion. Thus it will readily be seen that by two revolutions of the cam-shaft A and cam B but one reciprocation ot' the pitman F is accomplished.
Having now fully described my invention and the manner inWhiohI have embodied it, what I claim as new, and desire to secure by Letters Patent, is-
1. The cam B, having portions N O eccentric to each other, around both of which portions the track L is Jformed, constructed and arranged to operate substantially in the manner and for the purposes specified.
2. The cam B, having portions N O, the pitman F, cam-roll C, vibrating rod D, lug J,
guidezpins M, and shaft A, all combined and arranged to operate substantially as specified.
