POWER-CONVERTER FOR CONVERTING RECIPROCATING INTO ROTARY MOTIO N.

SPECIFICATION forming part of Letters Patent No. 253,515, dated February 14, 1882.

Application filed December 27, 1881. (No model.)

To all whom it may concern Be it known that I, HENRY GROFT, Jr., residingat Springfield, Clarke county, Ohio, have invented certain new and usefulImprovements in Power-Converters for Converting Reciproeating into Rotary Motion, and it is designed especially for a power-converter for wind-engines, of which the followingis a specification.

In this class of machines there is usually a vertically-reciprocatin g pump-rod operated by a crank or eccentric on the wind-wheel shaft,

and it has long been a problem to utilize the power of the wind-wheel for grist-mills, cornshellers, and the like machinery. I am aware that machinery for this purpose has been designed before, butfor various reasons has failed in producing satisfactory results with small wind-wheels or those of comparatively limited power.

My present invention has for its object the utilization of the largest per cent. of the power of the wind-wheel for the purpose of running machines of the class above designated, orgenerally any machinery within the power of the wheel.

The novelty of my invention consists in the combination, with the reciprocating pump-rod and the driving-wheel of the motor-engine, whose shaft is provided with ratchets, of alternately-aetin g dogs operated from the pump-rod through the medium of links and levers,whereby a continuously-revolving motion is imparted to the driving-wheel; also, in details of construction and combinations ofthe parts, as will be herewith set forth.

In the accompanying drawings, Figure 1 is a side elevation of my apparatus. Fig. 2 is an end view of the same. Fig. 3 is an enlarged detail view of the ratchet and dog-carrying link with one side broken away. Fig. 4 is a plan view of the ratchet, dog, and link.

The same letters refer to like parts in the difl'erent figures.

A, Fig. 2, is the lower end of the pump-rod,

which works up and down in the usual way. It is pivoted by means of the link a to thevibrating cross-beam 13, which is pivoted at its center 12 toany suitable frame-work. The two beams G G are pivoted by means of links a to the ends of the vibrating beam B in any suitable manner. Upon the lower beams, O (J, are secured metal links d, in the lower end of which are pivoted the slotted blocks D.

In any properly-constructed framework, E, is journaled a shaft, F, carrying a drivingwheel, G. Upon the outer ends of shaft F are keyed or otherwise fastened ratchet-wheels H. Straddling each of these ratchets and hung upon the shaft F are links I, with rearward extensions which pass through the slot in the links d, and are held adjustably by set-screws f, inserted through the tops of the links d.

Pivoted in or near the forks of the links I,

are dogs J which engage with the ratchets, as shown, and may be held to place by gravity or by any suitable superimposed springs.

I By the above construction it will be readily understood that as the pump-rod A moves up and down the beam B is vibrated upon 'its pivot, and an alternating reciprocating motion is given to the beams G and 0. These in turn vibrate the dog-carrying links with alternate motions, so that while the one by means of its dog is rotating its ratchet,and with it the driving-wheel, the other is being depressed, carry-, ing its dog back for a fresh engagement with its ratchet, and vice versa. Thus a constant revolution is imparted to the driving-wheel G in one continuous direction.

By means of the adjustability of the links I in the slotted blocks D eitherdog may be given a greater or less amount of play, and so either the up or the down stroke of the pumprod may be favored, as desired. This same object may be accomplished by rendering the pumprod or the beams O O laterally adjustable.

I prefer that the driving-wheel should have sprockets upon its periphery, so that a chain may be used for communicating motion to the driven machinery, instead of belts, though the latter may be used, if desired.

- I do not wish to limit myself to the precise construction andarrangement shown, as this may be varied without departing t'rommy invention. For instance, the pump-rod, instead of being coupled to the beam B at a point between its pivot and that of one of the beams G or 0, may be coupled to an extension of the beam beyond either of the beams, so as'to obtain a longer leverage and greater power, though at a sacrifice of the length of stroke of the dogs; also, instead of ratchet-Wheels and dogs, spring-clutches might be employed,'or.

5 the Wheels H might have smooth peripheries and friction gripes or rollers be used.-

Having thus fully described my invention, I claim- 1. In a power-converter, the combination, 10 with a driving-wheel whose shaft is provided with ratehets arranged on each side of the driving-wheel, of a vibrating pivoted beam actuated by the reciprocating rod and carrying at its ends beams provided at theirlower ends I 5 with dogs and connecting mechanism, substantially as described, whereby the vibration of
