MECHANICAL MOVEMENT.

SPECIFICATION forming part of VLetters Patent No. 759,648, dated May 10, 1904.

Application iled July l0, 1901. Serial No. 67,745. (No model.)

To all whom it may concern:

Be it known that I, ADoLrH VVAHLE, a citi- Zen of the United States, anda resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Mechanical Movements, of which the following' is a full, clear, and exact speciiication.

My invention relates to mechanical movements for converting a continuous rotary movement into a reciprocating rotary movement for use in a variety of machines, such as ehurns, washing-machines, or the like.

My invention consists in the matters hereinafter set forth, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a View in side elevation of my' invention, illustrating its application to a washing-machine, the upper portion only of the latter being shown and this in section. Fig. 2 is a view in side elevation of the translating devices, the remainder of the mechanism being removed, the point of view being opposite to that of Fig. 1. Fig. 3 is a view in end elevation of the parts shown in Fig. 2.

Referring to the drawings, a drive-wheel A is shown as journaled on a stud projecting from one end of a main supportiiig-frame B and as communicating its continuous rotary motion to a drive-shaft F through the medium of a pinion D, secured concentrically to the hub of the drive-wheel, and a gear E on the adjacent end of said drive-shaft in mesh with said pinion. If desired, the drive-wheel can be secured directly to the end of the driveshaft, its connection therewith, as shown in the drawings, being simply for the purpose of increasing the power transmitted to the drive-shaft. Said drive-shaft F is revolubly secured in bearings on the frame B, and at its end portion remote from the gear It, which projects through and beyond the bearing it is provided with an angular dellectionf, which forms an oifset or bend, the return leg or stretch of which, hereinafter designated as the angular extension If', is in a plane oblique to the axis of the shaft F, which latter' intersects it, preferably at its center of length. As a consequence of the Obliquity of position of the angular extension f' the rotation of the main shaft of the shaft F causes the angular extension to describe by its movement a double cone, and a section taken on a plane of the axis of the straight portion of the shaft F through the path of motion of said angular extension shows an angular oscillatory motion of said extension. The purpose of my invention is to convert this angular movement of the extension into an oseillatory reciprocating motion, eliminating the effect ofthe rotary motion of the extension around the shaft-axis. To this endl secure on said extension f a sleeve J in such a manner as to revolve freely thereon,while at the same time preventing' longitudinal displacement thereof. As a convenient meansof effecting this a feather-pin y' is employed, which secured to and projects radially from said angular extension into an annular groove or lreywayj, which is formed on the interior surface of the sleeve and for a portion of its circumference extends entirely through the wall of the sleeve in order to form a slot through which the pin may be inserted when the sleeve is positioned on the extension. Obviously, however, any other well-known mechanical device may be employed to secure the sleeve J against longitudinal displacement.

Projecting from sleeve J', at an angle of about ninety degrees to the plane of its pivotal contact with extension j", is an arm K, which extends sidewise and then downward in a transverse plane striking through the point where the axes of the straight portion of shaft and of said extension intersect. The end portion of said arm l( farthest from sleeve .I is preferably cylindrical and is journaled in a plane at right angles to the axis of said sleeve in a pivotal socket formed in the web of a segmental rack L. lihe segmental edge of rack L extends beyond the teeth of said rack and. is seated and has a sliding peripheral movement in the correspondingly-curved runway di of the track f, which latter is integral with the base-plate of the supporting-frame Band arranged in a plane parallel with the axis of the drive-shaft F. The motion imparted to the segmental rack by the angular extension j" through the medium of arm K causes it to os- IOO section or the center of oscillation of said angular extension. In order to allow perfect freedom of motion between said arm K and the rack L, I adapt the outer portion of the arm K to have rotating' engagement in said socket, thereby effectually providing .for unequal wear or accidental distortion. To convert this oscillating reciprocal motion of the circular rack L into a reciprocating motion, I mesh therewith a gear H, which is secured, as illustrated in the drawings, on a shaft G, which latter is revolubly secured in bearing's 52 and Z13 on the main frame B. As shown in the drawings, said shaft Gr is mounted at right angles to the drive-shaft F; but it is obvious that it may be secured at any angle to the shaft F, so long as it lies in a plane permitting proper engagement of the gear H and rack L.

The operation of the mechanism as a whole is obvious. A continuous rotary motion is imparted by the driving-wheel A to the driving-shaft F. The movement of the latter causes the rotation of the angular extension and at the same time an angular or rocking motion of the latter on its center of oscillation, which latter, as before stated, corresponds to the intersection of the axes of the two parts of the shaft. Said angular' or rocking movement is communicated to the sleeve J and its projecting arm K, and these in turn impart an oscillatory motion to the curved rack L. The latter therefore is caused to move reciprocally in its runway, and so imparts a reciprocal rotary motion to the gear H and the shaft Gr.

There is an absence of the usually employed gears and resultant decrease in loss of power by friction, while it is evident that the parts may be constructed and assembled very easily.

I claim as my invention- 1. A device for the purposes stated comprising a continuously-rotating shaft, a portion of said shaft being bent at an angle oblique to the main portion of the shaft, an oscillating' curved rack, having a socket extending radially from the inner edge thereof, a sleeve rotatively secured on said oblique portion of the shaft, an arm extending from said sleeve having' rotative engagement with said socket, and a reciprocating rotary shaft actuated by said rack.
