POWER MECHANISM.
SPECIFICATION forming part of Letters Patent No. 636,409, dated November '7, 1899.
Application filed May 13, 1899. Serial No. 716,640. (No model.)
To aZZ whom it may concern.-
Be it known that I, HARRY D. LEEKING, a citizen of the United States, residing at WVitmer, county of Lancaster, State of Pennsylvania, have invented certain Improvements in Power Mechanisms, of which the following is a specification.
This invention relates to improvements in that class of mechanismsjwhereby power received through rotary motion is transmitted by a reciprocating movement; and the object of my improvements is to produce a plurality of movements of the reciprocating member of the mechanism with each complete revolution of the rotary member thereof;
The invention consists in the details of construction and the combination of the various parts, as hereinafter fully described, and then pointed out in the claims.
In the accompanying drawings, which form. a part of this specification, Figure 1 is a front elevation of a mechanism embodying my invention; Fig. 2, a transverse central section, and Fig. San elevation, of the side of the device to which the power is applied shown detached from the base. Fig. 4 is aview of the inner face of the guide-plate and of the connecting-rod, and Fig. 5 a similar view of another form of said plate and of the connecting-rod. Fig. 6 is an inner face view of the cam-plate; Fig. 7, a similar view showing the shoulder-plate engaged therewith; and Fig. 8, a like view with the shoulder-plate engaged in the cam-plate, but in a somewhat different position from that illustrated in Fig. 7, the connecting-rod being cut away. Fig. 9 illustrates a modification of the shoulder-plate. Fig. 10 is a vertical section on broken line 10 10 of Fig. 2, showing the connection between the shaft and a plate attached thereto, the outer portions of said plate being cut away.
Similar letters and numerals indicate like parts throughout the several views.
Referring to the details of the drawings, A indicates the base supporting the operating mechanism, and B a post set in base A and having a recess b in the upper end thereof, wherein rests the shaft E, to be described.
D indicates an annular guide-plate having a foot (1, which engages a socket a in base A and which is firmly held in position by angleplates A, bolted to said foot and to base A, as shown in Figs. 1 and 2. Guide-plateD is also provided with an annular flange R, which takes over the periphery of camplate G, to be described.
Shaft E is supported in recess b of post 13 and an opening 01 in guide-plate D, and it has on one end, outside of post B, a crankwheel E, provided with a wrist-pin E whereby power is applied, and on each side of post B there is a collar 6, rigidly affixed to said shaft, to prevent longitudinal.inovement of the same.
Inside of post B an annular plate F is rigidly secured to shaft E, said plate having a rectangular opening in which fits the squared section 1 of said shaft, and to the inner face of said plate F a cam-plate G is secured by screws or bolts f passing through plate F and into holes f in said cam-plate. An opening is cut through the cam-plate, which opening has the general outline of an equilateral triangle wherein the apex of a cam g is located in the center of the wall of each side, and the angles between the sides have substituted therefor curved surfaces forming sockets g, as clearly shownin Figs. 6, '7, and 8, the parts of the wall connecting the cams and the sockets being curved surfaces. The open face of said cam-plate sits up flush against the L, as will be described. This shoulder-plate is an elongated oval in outline, of the same depth as the cam-opening in cam-plate G and of a length equal to the distance from the apex of each cam to the center of the opposite socket, the curved ends of the camplate being adapted to fitthe sockets. Through the end h of connecting-rod H and the shoulder-plate L is an elongated oval slot H therefor of greater width than the diameter of shaft E and wherethrough passes aid shaft E. Shoulder-plate L is secured to he driven end 72, of the connecting-rod by screws or bolts 2 or in any other well-known way. Motion is imparted to the cam-plate through crank-wheel E and shaft E, whereby a reciprocating movement is given connecting-rod H through the engagement of-shoulder-plate L with the walls of cam-opening 99. In Fig. 4: the mouth (1 of channel D is wider than driven end h of connecting-rod H, forming opening H of shoulder-plate L of greater width than the diameter of shaft E, and constructing the longitudinal walls of channel 1) of guide-plate D with concave faces gives the ends of connecting-rod H a vibrating as well as a reciprocating motion, as when the driving end of said rod is applied to the wrist-pin of a wheel, and widening the mouth d of said channel D adds to the free dom with which the vibrating movement is made.
In Fig. 5 the walls of channel M are parallel and the mouth of said channel is of the same width as the end ft of the connectingrod, whereby simply a reciprocating movement is imparted to said connecting-rod. The shoulder-plate also differs in shape from the shoulder-plate first described, the ends being angular in outline, as shown, instead of rounded.
The construction of the walls of cam-opening g g and of the sides of shoulder-plate L is such that some part of the ends of said shoulder-plate is always in contact with some portion of the walls of the cam-opening.
Fig. 9 illustrates a shoulder-plate provided with antifriction-rollers to reduce the friction of said shoulder-plate and the walls of the cam-opening.
Power may be applied to shaft E in any well-known manner, and it is not necessary that the back of the cam-plate be closed, for said cam-plate may be secured on shaft E by other means than plate F.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination, in a power mechanism, of a shaft, a cam-plate rigidly secured on the shaft and provided with a series of cams arranged about its center and having a socket located opposite each cam, an immovable guide-plate provided with a channel having its open side toward the cam-plate, a connecting-rod in the channel of the guide-plate, and a shoulder-plate 011 the connecting-rod and engaging the cams of the cam-plate, the shaft passing through a slot in the connecting-rod and the shoulder-plate, for the purpose specified.
2. The combination, in a power mechanism, of a shaft, a cam-plate rigidly secured on the shaft and provided with a series of sockets, convex walls connecting the sockets and forming the cams of the cam-plate, an immovable guide-plate provided with a channel having its open side toward the cam-plate, a connecting-rod in the channel of the guide-plate, and a shoulder-plate on the connecting-rod and engaging the cams of the cam-plate, the shaft passing through a slot in the connectingrod and the shoulder-plate, for the purpose specified.
3. The combination, ina power mechanism, of a shaft, a connecting-rod, a cam-plate rigidly secured on the shaft and provided with a series of cams arranged about its center and having a socket located opposite each cam, curved walls connecting the cams and sockets, an immovable guide-plate provided with a channel having concave longitudinal sides, a connecting-rod in said channel, anda shoulder-plate on the connectin g-rod and engaging the cams of the cam-plate, there being an elongated slot through the connecting-rod and the shoulder-plate and of greater width than the diameter of the shaft, the shaft passing through said slot, for the purpose specified.
4. The combination, in a power in echanism, of a shaft, a connecting-rod, a cam-plate rigidly secured on the shaft and provided with a series of sockets, convex walls connecting the sockets and forming the cams of the camplate, an immovable guide-plate provided with a channel having concave longitudinal sides, a connecting-rod in said channel, the mouth of said channel being of greater width than the connecting-rod, and an elongated oval shoulderplate on the connecting-rod and engaging the cams of the cam-plate, there being an elongated oval slot through the connecting-rod and the shoulder-plate and of greater width than the diameter of the shaft, for the purpose specified.
5. The combination, in a power mechanism, of a post, a stationary upright guide-plate having a channel therein, a shaft journaled in the post and the guide-plate, a wheel rigidly secured to the shaft and having a camopening therein, the inner face of said wheel being flush against the guide-plate, three cams formed by the wall of said opening and arranged symmetrically about the center, a socket being formed by said wall opposite each cam, the wall forming a curved connection between the cams and the sockets, a connecting-rod having an end in the channel of the guide-plate, the mouth of the channel being wider than said end of the connectingrod, and an elongated oval shoulder-plate on the connecting-rod and adapted to have both ends thereof in continuous engagement with the wall forming the cam and the sockets and the curves connecting the cams and the sockets, the shaft passing through an elongated oval slot in the shoulder-plate and the connecting-rod and of greater width than the diameter of said shaft, substantially as and for the purpose specified.
