MEANS FOR CONVERTING OSCILLATORY MOVEMENT INTO RECIPBOCATORY MOVEMENT.

Application filed May 4, 1915.

To all whom it may concern:

Be it known that I, JAMES BRUCE, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Means for Converting Oscillatory Movement into Reciprocatory Movement; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device for converting oscillatory movement into reciprocatory movement, and the primary object of the invention is to provide a device as specified, which may be utilized for operating water, air, oil or like pumps, air compressors or analogous mechanical devices wherein a reciprocatory movement of a rod or piston is necessary for enabling the device to perform its function.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail ref erence will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved mechanism for converting oscillatory movement into reciprocatory movement, Fig. 2 is an edge view of the devlce, Fig. 3 is a sectional view of the device, Fig. 4 is a cross section on the line 4.i of Fig. 3.

Referring more particularly to the drawings, 1 designates the supporting structure of the mechanism, which includes a pair of standards 2 and 3, which have their lower ends connected by a suitable head or block 4c. The standards 2 and 3 have a pin or shaft 5 carried by their upper ends, upon which is eccentrically mounted a disk 6. The disk (3 has a handle 7 secured thereto, by a T-iron 8 and a straight metallic strap 9. The T- iron 8 is secured to one side of one end of the handle 7 and one side of the disk 6, and the metallic strap 9 is secured to the opposite side of the handle 7 and the disk 6. The handle 7 projects radially from the periphery of the disk 6, and is provided for Specification of Letters Patent.

Serial No. 25,751.

moving the disk upon its eccentric pivotal support. The disk 6 is provided with a recess 10 formed in the periphery thereof, in whlch is mounted a slip ring 11. The ring 11 is loosely mounted in the annular recess 10 and is held against accidental removal therefrom, by the size of the ring. The slip ring 11 is constructed of a strip of metal, and it has its ends 12 and 13 extending out wardly therefrom, being spaced from each other, as is clearly shown in Figs. 1 and 2 of the drawings. The spaced ends 12 and 13 of the slip ring 11, have a pitman rod 14 secured thereto, which extends downwardly between the standards 2 and 3 and is pivotally connected to the piston rod 15. The piston rod 15 is slidably mounted in a sleeve 16, which is carried by and extends through the block or head 4. The piston rod 15 may be connected to the pitman rod 14, by having its end reduced, as is shown at 17, and seated between arms 18 and 19 formed upon the lower end of the pitman rod, by bifurcating the same, or in any other desired manner.

The oscillatory movement of the handle 7, will move the disk 6 upon its eccentric pivotal connection, and will move the slip ring 11 therewith. By the loose mounting of the slip ring within the annular peripheral recess 10, a reciprocatory movement will be imparted to the piston rod 15, through the connection between the slip ring' and the piston rod, by means of the pitman 14;.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations, to which the patentee is entitled, provided such alterations are com prehended within the scope of what is claimed.

lVhat is claimed is In a device of the class described including a supporting structure having a base, a pair of vertical parallel spaced standards secured to the base, a shaft journaled through the upper ends of said standards, a disk provided with an annular peripheral groove eccentrically mounted upon said shaft, T-shaped metallic straps secured by their crossheads to opposite faces of said disks their stems projecting beyond the periphery of the disk, a handle secured in the ends of said stems of the straps, a ring pivotally mounted in the annular recess, the ends of said ring being spaced apart and extending parallel from said disk, a pitnian rod removably secured between the parallel ends of said ring and extending downwardly therefrom, and located between the standards, a piston rod projecting through the base of said standards, a sleeve surrounding said piston rod, the upper end of said piston rod connected to the lower end of the 10 pitrnan rod whereby upon oscillatory movement of the handle the same imparts motion to the disk, and a reciprocating motion will be given to the pitlnan rod and the piston substantially as set forth.

In testimony whereof I afliX my signature 15 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, I). G.
