WlNDMlLL-MOTOR.

SPECIFICATION forming part of Letters Patent 1\ To. 252,737, dated January 24, 1882.

Application filed October 15, 1881. (No model.)

To all whom it may concern:

Be it known that L'BLANCHARD CHAMBER.- LAIN, a citizen of the United States, residing at Bellefontaine,in the county ofLogan and State of Ohio, have invented a new and useul Improvement in Windmill-Motors, of which the following is a specification.

My improved device is adapted to be clipped to the vertical pitman or reciprocating rod of a windmill, and to convert the reciprocating motion thereof into continuous rotary motion, while entirely avoiding dead-centers. For this purpose I employ an oscillating yoke having racks on its oppgsite sides and pivoted at top to the clip which is conveniently fixed to the pump-rod, a pair of pivoted arms being used in connection with the oscillating rack-yokes for guiding the same in its vertical movement and placing its respective racks into gear with the opposite sides of the driving-pinion alternately as said racks are carried up and down.

In order that my invention may be fully understood, it will be explained with reference to the accompanying drawings, in which- Figure l is an elevation of a windmill with the invention applied. Fig. 2 is a face view of the guides and pinion on a larger scale. Fig. 3 is a perspective view of the rackyoke detached. Fig. 4 is a plan or top view of the clip and stud by which the rack yoke is attached to the pump-rod.

A may represent a wind-Wheel of any form or construction mounted on a suitable tower or standard, B, and having on the rear extremity of its shaft (3 a crank-wheel, D, which runs a reciprocating rod, E, in customary manner.

A suitable pump is shown at 'F.

G is the oscillatiugrack-yoke of my improved motor. It is provided on each side with an inwardly-projecting set of cogs or teeth, g g, and at bottom with three studs, h z'j.

k is an aperture at top of the yoke by which it is suspended from a stud, l, projecting from the face of the clip L, the arms m m of which receive a clip-plate, N, and nuts '02, by which the device is securely fastened to the pump-rod E. The stud Z has an aperturenear its extremity for the reception of the split key 0, to retain the oscillating rack-yoke upon it.

P is a plate or standard forming one partof the stationary frame of my motor. In the said frame are bearings for the pinion-shaft Q, on which are a pinion, R, and a fly-Wheel, S.

T T are a pair of guiding-arms, pivoted on studs 15 1., respectively, and pressed inward toward the center by springs U U, the inward movement of said arms being arrested by studs 1; v, the-first of which may be near the heel of the arm, while the stud c is in position to receive the contact of the upper end of the arm T, which is thrown against it.

WV represents a central guide consisting of a vertical rib projecting from the face of the plate P.

a; is a stud a little on one side of the lower end of the guiding-rib W.

The oscillating yoke is confined to its proper plane of movement by a strap, Y,bolted atits ends to the face of the plate P.

In order to prevent noise, rubber cu'shionsz are placed on the studs 0;, c, and a, and cushions z on the faces of the arms T T where they come in contact with the respective studs.

The operation is as follows: Supposing the parts to be in the position shown in Fig. 1, the pump-rodis now ready to make its upward stroke. At this time the pressure of the guiding-arm T on the stud it throws the bottom of the pivoted yoke'to the right, by which means the rack g on the left side is placed in position to gear with the left side of the pinion It and rotate the shaft and fiy-wheel in the direction indicated by the arrow. This upward stroke, bringing the right-hand studj in contact with the guiding-arm T, moves the same to the right, while the pressure thereof holds the central stud,i, in close contact with the right hand side of the vertical guiding-rib W until the said stud, reaching the top of said rib, is arrested by the upper fixed stud, o, projecting from the plate P. At the same time thepressure exerted by the spring of thcpivoted guide-arm T throwsthe yoke to theleft, bearing the righthand studj of the yoke against the side of the ICO right side of the pinion It, and continue the rotation of the shaft and fly-wheel in the same direction as indicated by the arrow. During the downward stroke the left-hand stud h presses the left-hand spring-arm T sidewise in the manner already described with reference to the right-hand arm until the central stud, i, reaches the bottom of the vertical guiding-rib W, when it is thrown sidewise until arrested by the bottom stud, a:, when the upper stroke is performed as before, a continuous rotary motion being thus imparted to the shaft.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In combination with the vertical reciprocating rod, the vibrating raok-yoke G, pivoted thereto, and the pivoted guide-arms T 1", pressed inward by springs UU, theguide-arms being intermediate of the springs and rack- 20 yoke, substantially as and for the purposes set forth.

2. The combination, with the vertically-reciprocating rod and the vibrating rack-yoke, of the detachable clip L for pivoting thevibratingrack-yoke to the vertical reciprocating rod, substantially as and for the purposes set forth.

3. The rack-yoke G, formed with cogs g g and studs h ij, as set forth.

4. The combination of the vibrating rackyoke, bearing-plate P, pivoted guide-arms T T, springs U U, central guiding-rib, W, and studs 0, o, and or, substantially as and for the purposes set forth.

BLANGHARD CHAMBERLAIN.
