Y' DEViCE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 286,596, dated October 16, 1883.

Application tiledv August 28, 1883. (No modela To all whom t inlay-concern:

Be it known that I, Cnnnrns H. Encin- Bnnoir, a citizen of the United States, residing at Alden, in the county of McHenry and State of Illinois, have invented a new and useful Device for Converting' Motion, of which the following is aspeciiioation, reference being had to the accompanying drawings.

This invention relates to devices for converting motion, and it has for its object to change the reciprocating movement oi' a windmill-pump shaft int-o a continuous rotary motion. f

To this end it consists of a shaft journaled in the windmilltower and carrying gearwheels arranged to move in opposite directions, said gear-wheels engaging with a rack which is attached to the end of the pump-shaft of any ordinary windmill. Thesedevices connect with suitable machinery for shelling corn, churning, Src., and thus, when the rack is reciprocated by the movement ofthe pump-shaft, this movement will be transmitted to the gearwheels, which will convert it into a continuous rotary motion.

My invention consists in the above-described construction, and in certain other details, as hereinafter fully set forth, and particularly pointed ont in the claims. v

In the drawings hereto annexed, Figure 1 is A a view of a' windmill-tower, showing the arrangement of my improved. devices. Fig. 2 is a perspective view of'my improved devices detached. Fig. 3 is a vertical longitudinal section on line y y, Fig.V 5; Fig. 4i is a similar view taken at right angles to Fig. 3. Fig. 5

is a horizontal sectionon the line e z, Fig. 3.

- Fig. 6 is a transverse section on the line, m a',

Fig. 4.

Like letters rei'er to corresponding parts in the several figures.

Referring to the drawings, A designates the windmill-tower, of any ofthe well-known forms oi' windmills, and B the pumping-shaft thereof, operated in the usualmanner.

Journaled inthe tower is a shaft, C, which is held from working out through its journals by means of collars c, Ahaving set-screws c', said shaft carrying two setsoi' devices acting independently of one another, said devices Voperating to convert a reciprocating movementV into a rotary motion.

D D designate gear-wheels working loosely lar plates E E', secured to the back of the gear-wheels, said plates having square-shaped blocks F F formed therewith. Suitablylaround the shaft C, and provided with circushaped recesses f f are cut from the blocks,

The inner portion of It will be seen that the heads g g of the pawls iit within the recesses f f', which are shaped to retain the heads and yet allow `free movement of the same, the front ends of the pawls projecting a short distance beyond the i blocks F F', so as to readily engage with the ratchet-teeth in the caps. Two pawls are used for each of the gear-wheels D D', and engageV with the ratchetteeth in the caps, the extended corner Z of the blocks limiting the play of the pawls. arrangement of the pawls, and the ratchetteeth in the caps are arranged in different positions for each of the gear-wheels D D. .Thus as shown in the drawings, the position of the pawls G, the manner of iitting the same in the blocks, and the arrangement of ratchet-teeth j are all reversed in the gear-wheel D, so that when the gear-wheel D is operated it will revolve independently on the shaft, since the pawls G will 4slip 'readily over the ratchetteeth j, while when the wheel D is operated the pawls G will be engaged withthe teeth j', and said wheel D cannot slip or revolve loosely around the shaft.

I designates a loose wheel fitted on shaft A, between the gear-wheels D D', said loose wheel running on a continuous track, J, formed in-` side the elliptical -shaped rack or frame K, around the middle portion. A series oi' teeth, L, is formed on opposite sides oi' the rack, out

side the track J, the gear-wheels D D meshing with said teeth when the rack isreciprocated, while the loose wheel I serves to hold the wheels in mesh only at a certain depth. The rack or frame is formed at its upper and lower ends with extensions M, to the upper one of which is attached the pumping-shaft of any ordinary windmill, so that when the shaft is reciprocated a similar movement will be transmitted to the rack. As the rackdescends the gear-wheels D D are revolved and engage with the teeth L, the loose wheel I guiding the gear-Wheels in their movements. By the revolution of the gear-wheels, the blocks, with their pawls, are carried aroundinside the caps, the pawls G of wheel D being disengaged from the ratchet-teeth j of the cap II, so that said gear-wheel will revolve independently of shaft A without turning` its cap, while, the pawls G of the wheel D being engaged with the ratchet-teeth j, the cap H will be revolved, there- K gaged, and thus the cap II will not be opery tion are obvious.

by turning the shaft A. 'Vhen the rack aseends, the wheels D D are operated in a reverse direction, the pawls G of wheel D being engaged with the teeth 7 inside the cap II, so that said cap will be revolved, causing the continual revolution of the shaft A, while the pawls G of the other wheel, D, will be disenated. This reciprocating movement is kept up,and will be converted into a continuous rotary motion, which will be imparted to the shaft A, the latter having at one end apulley, N, connecting by a belt,` 0, with the operating-shaft of a corn-shelling machine, churn, washing-machine, or any other suitable means.

The operation and advantages of my inven- The construction is simple and durable, and works with admirable efficiency in converting a reciprocating movement into a rotary motion.

. It will be obvious that various modifications may be resorted to without departing from the spirit or scope of my invention.

Having described my invention, I claim as newf 1. In a device for converting motion, ashaft journaled in the windmill-tower, and carrying two gear-wheels separatedby aloose wheel, I, iny combination with a rack or frame connected with the windmill-pump shaft at the upper end, said rack being provided with teeth on opposite sides, and a continuous track separating the teeth, the wheel I running on said track, for the purpose set forth.

2. In a device for converting motion, a shaft journaled/in the windmill-tower and `carrying two gear-wheels, between which works'a loose wheel, I,-and caps fitted over the outer ends of the gear-wheels and connecting with the same, in combination with a rack or frame connecting with the operating-shaft at the upper end, and provided with teeth on the inside, and a continuous track between the teeth, said rack rotating the gear-wheels in opposite directions. while the wheel I runs freely on the track, and means, substantially as described, for permitting the free rotation of one of the gear-wheels, while the other wheel turns its cap, and thereby imparts motion to the shaft, as set forth.
