WINDIVIILL MECHANISIVL.

Specification of Letters Patent.

Patented ct. 12, 1909..

To all 'whom it may concern.'

Be it known that I, IRA C. RUST, a citizen of the United States, and residing at Farmland, in the county of Randolph, State of Indiana, have invented new and useful Improvements in lVindmill Mechanisms, of which invention the following is a specification.

This invention pertains to improvements in power transmitting means wherein rotary movement is converted into reciprocatory motion, and it has morel especial reference to mechanisms of wind mills. In this class of mills it is very desirable that the motion furnished by the rapidly rot-ating wind wheel, shall be so converted and transmitted that the member or rod which operates the pump or other machinery, willA have imparted to it a positive regular and steady movement.

To accomplish the aforesaid desirable results, are the objects, broadly stated, of my invention.

Further objects of my present invention are to provide a power and mot-ion transmitting means which may be easily rendered inoperative and the wind wheel may be held against rotary movement.

Other and more specific objects are to provide a device of the kind described which will be substantial and strong, not liable to get out of order or repair, and which will be economical of construction. and easy of installation.

The aforenamed objects of my invention are accomplished by and my invention is embodied in the new construction, combination and arrangement of parts described in this specification, defined in the appended claims, and illustrated in the accompanying drawings.

Similar characters of reference refer to corresponding parts throughout the several views in the drawings, in which- Figure 1 is a side view, Fig. 2 is an end view, and Fig. 3 is a plan view of my invention complete, the central portion in the first named View being shown in section. Fig. 4 is a detached transverse sectional view of the cam member and upright shaft removed. Fig. 5 is a horizontal plan view taken on the line A Fig. 1. Fig. 6 is a horizontal plan view taken on the line B Fig. 1.

From the base 1 of the framefof my improved mechanism rise the upwardly disy posed arms2 and 3.

Journaled. in suitable bearings carriedby the said arms is the shaft 4 upon the outward portion of which is se- .cured the hub-of the wind wheel and which hub may be of any acceptable style or structure. Projecting from the arm 3 is a lug 5 upon the end of which is fastened the fixed end of the brake band 6. This flexible brake band is of proper form to engage the peripheral face of the said hub, and its lower end is fastened to the short arm of the lever 7 which is pivotally supported onthe lug 8. This lever is so formed that the free end thereof will occupy the position relative to the frame, as plainly shown'in the drawings.

The bottom portion 2a of the arm 2 has al vertical bore in which the upright shaft 9 is journaled. The upper portion of the arm 2 has a` horizontal bore or recess in which the inner end o f the shaft 4 is journaled. The center point of the base portion 1 is to onel side ofthe center line of the shaft so that there will be ample clearance between the said shaft, and the vertical reciprocatory bar 10. As a meansto. sustain the reciprocatory bar 1() in correct central position in the bore 1l of said base portion, there is provided the guide block or bushing 1Q suit.- ably secured in position and having an aperture in which the bar 10 is free to move slidingly. The shoe 13 has its upper portion of proper diameter to fit within said central bore, where it is held by set screws 132 Screwed tightly into the shoe is the hollow upright member 14 which extends downwardly through the. platformk of the tower upon which themill 1s carried. The lower end of this upright is free to move rotatively but is held against transverse movement by the spider 14a which is secured to the tower structure. The platform 15 which is suitably supported in fixed position by the tower structure 16, has a central opening through which the aforesaid upright 14 is easily passed. Complemental annular races in the facing surfaces of the shoe and the platform form runways between which are disposed the balls 17. By this construction and arrangement of the several parts the frame has the usual free pivotal movement, and will be sustained in correct vertical position.

It will be understood that a swivel connection (not shown) ata proper location inl the rod 10 is provided, so that the rod will by the arm 19 is the strong buffer spring 21 the free end of which spring will bear against the lug 22 carried by the frame. The normal position of the vane beam with reference to the frame, when the mill is operating, is that shown in Fig. 5, the vane beam is held in the position shown, by the coil spring 23 which has its one end fastened to Ythe arm 19 and the other to the frame proper.

The outer ends of the arm 19a and the lug 22 are suitably widened and recessed so as to let the coil spring 23 rest and move therein. Carried by the arm 20a is the buffer spring 24 the function of which will presently be referred to.

On a bracket 25 carried by the frame, is the grooved pulley 26. A cable or rope that is fastened to the arm 20 is passed over this pulley thence over a grooved pulley 27 that is carried loosely on the shaft L1, thence downwardly through the perforation 12a in the guide block 12. This cable is sufficient in length so that a person standing on the ground at the base of the tower may manipulate same. Then the cable is pulled downwardly the vane beam will be moved around into the dotted line position shown in Fig. .6. As this position of the vane beam is reached the windv wheel will no longer stay in the wind and by the pressure of the arm 20a against the brake'lever 7, the brake band is quickly tightened against the hub of the wind wheel and the latter will be held against rotation. The attendant may then secure the cable so that the vane beam may be kept in the inoperative position. To prevent undue jar of the frame and to prevent too sudden actuation of the brake lever, when the operation of throwing around the brake beam is performed, as just described, is the function of the buffer spring 24. With the pulling down of the cable and the moving of the vane beam, as the latter reaches the dotted line position, the buffer spring strikes the base portion of the frame in advance of the engagement by the arm 2O*l of the lever 7. On the inner end of the shaft et is secured a bevel gear wheel 28 which meshes with the gear wheel 29. This gear wheel 29 is loosely disposed on the upright shaft 9, and the upper face of its hub is toothed, as shown in F ig. 1, and Fig. 2 to receive the complementally toothed hub of the cam wheel 30. The structure and position of this cam wheel is plainly shown in Figs. 1, 2 and 3, the

eeases 4by a wind wheel, said cam to actuate a reciprocatory member, is shown in Patent No. 913,918, granted tome March 2, 1909. Since the construction of the device shown in said patent, my present invention has been developed and perfected.

In the present invention the conformation of the web of the cam wheel is such that as the cam wheel is rotated, the movement of the reeiprocatory bar 10 is decidedly more rapid in its downward stroke than upon its upward stroke, the desirability of which is obvious. The time necessary for the reciprocation of the bar 10 is so conserved that, (in the proportionate ratio as shown) the lift n'iovement is given two thirds, and the downward stroke one third of the time necessary for the rotation of the cam wheel.

By the new combination, construction and arrangement of the several parts my invention is rendered of practicable utility for any desired stroke of the pump piston. Cain wheels having different forms of webs to accommodate pumps of greater or less stroke, or for pumping material of varied specific gravity, may be supplied. The upper portion of the hub of the cam wheel is of such length that when the to i member 33 which forms the upper boxing for the upright shaft 9, and the guide head for the reciprocatory bar l0, is bolted into position on the upper end of the arm 3, the parts will all be retained in the correct position as shown, and the frame will be complete.

It will be understood that minor changes may be made in the conformation and detail construction and arrangement of the several parts, within the scope of my invention as the same is defined by the appended claims without departing from the nature or spirit of my invention, and without sacrificing any of its advantages.

that I claim as my invention and desire to secure by Letters Patent of the United States, is-
