POWER-TRANSMITTER.

SPECIFICATION forming part of Letters Patent No. 484,066, dated October 11, 1892.

. Application filed April 7,1892- Eerial No.

To all whom itmay concern.-

Be it known that I, ARNE S. TRAGETHON, a citizen of the United States, residing at Kensett, in the county of Worth and State of Iowa, have invented a new and useful Power-T ransinitter, of which the following is a specificaion.

This invention relates to power-transmitters, and particularly to those used in connection with windmills for transmitting power to grinding or pumping apparatus; and it has for its object to provide an improved device of this character by which the power received from the windmill will be converted into a continuous and rapid rotarymovement.

To this end it is the main object of this invention to generally improve upon the ,construction and operation of power-transmitting devices.

With these and many other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and. arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a plan view of a power-transmitter connected with a grinding-mill and constructed in accordance with the present invention. v Fig. 2 is a vertical longitudinal sectional view of the power-transmitter and a portion of its sup porting-frame. Fig. 3isa vertical transverse sectional view thereof. Fig. 4. is a detail in perspective of the reciprocating frame and a section of the swinging pawl-carrying frames and a pair of the pawl-levers connected therewith.

Referring to the accompanying drawings, A A represent opposite vertical frames supporting the horizontal frame-pieces B. The said horizontal frame-pieces B are provided near one end alongside of one of said vertical framesAwith the boxes 0, in which are journaled the ends of the horizontal rotating shaft D. Centrally secured to said horizontal shaft D is the intermediate actuating ratchet-wheel E, from which motion is communicated to the shaft D bythe mechanism to be described. 011 each side of the ratchet-wheel E and ,be-

tween the collars F, secured to said shaft, are the opposite swinging pawl-carrying frames G. The said pawl-carrying frames Gr comprise the opposite parallel arms g,having perforations g at one end, loosely taking over the shaft D on each side of the ratchet-wheel, and also provided with a series of adj ustment perforations g arranged longitudinally therein; Pivoted between the arms g of each pawlcarrying frame in front of the ratchet-Wheel are the driving-pawls H, one pawl in one frame being adapted to engage the ratchet.

wheel on one side, while the opposite pawl is running freely over the teeth on the other side of the wheel, so that when the swinging pawl-carrying frames are raised only one of the pawls engage the ratchet-wheel to rotate the shaft, while, on the other hand, when the said frames are lowered the opposite pawl engages the ratchetwheel to rotate the shaft in the same direction. Located directly behind the driving-pawls H and within the carryingframe are the pawl-stops h, which prevent the said pawls from swinging too far forward or backward, said pawls being connected with said stops by the springs h, which normally hold the pawls in engagement with the teeth of the ratchet-wheel.

Working over'the shaft D, outside of the collars F, is the vertically-reciprocati11g frame I. The said frame I comprises opposite connected parallel bars J, each provided with elongated longitudinally disposed slots K, Working over the shaft D as the frame reciprocates. Said bars are connected at their upper and lower ends by suitable connectingbars L, the upper of which is connected with the windmill-rod, which reciprocates the ver tically-reciprocating and slotted frame. Pivotally secured at one end to the upper and lower ends of the reciprocating frame I are the opposite pairs of connecting-rods M. The rods M are provided at their free ends with the inwardly-projecting pins m, which are de-' signed to engage any one of the series of adjusting perforations g in each of the parallel arms 9 of the pawl carrying frames. The said rods are arranged in pairs on each side of the shaft and connected with each of the in sectional View, Fig. 3, of the -draw-ings.-

The order is reversed on the other side of the shaft; but one rod isalso connected with one arm of the pawl-carrying frame, while the other rod is connected to the'other arms Thus it will be readily seen that as the recip rocating and slotted frame is raised the upl per one on each side of the shaft pulls the opposite swinging pawl carrying frames upward, while the lower rods tend to lift the same in the same upward direction, while, to the contrary, when thereciprocating frame I is lowered the upper rods push the pawl-carrying frames downward, while the lower rods pull said frames in the same direction. As the said reciprocating frame is rapidly reciprocated from the windmill, the rods M will carry the opposite swinging pawl-carrying frames rapidly up and down over opposite sides of the ratchet-wheel E, and on account of the disposition of the pawls one of the same will be continuously in engagement with the said ratchet-wheel, and both pawls will always drive the said wheel in one direction,.so that the shaft D will be continuously and rapidly driven.

A horizontal lever vN is centrally and pivotally supported to a suitable point of attachment above the upper end of the reciprocating frame I, and one end thereof is loosely connected to the block at, fitted in the upper end of said frame, while the opposite end of said lever is loosely connected to the attachment-plate N, which is connected to the windmill-rod, whereby a reciprocating motion is given to the Vertically-reciprocating frame I, while at the same time the windmill-rod may be connected directly to the pump-rod and not interfere with the operation of the transmitter, which is employed to operate other machines. Although this connection is preferred, yet it will be readily seen that the said reciprocating frame can be directly connected to and operated from the windmillrod. Securely keyed to the driving-shaft D outside of the driving mechanism thereof is the drive-chain wheel 0, around which passes the-driving-chain P, which is connected with the driving-pulleys of thegrinding-mill Q, located within the framework supporting the transmitter.

It Will be readily seen that both strokes of the windmill-rod are fully utilized by the power-transmitter and that a number of revolutions of the drive-wheel is obtained at every single stroke of the windmill-rod, and in this connection it may be noted that by adjusting he connecting-rod to and away from the ends of the opposite pawl carrying frames the speed of the driving-wheel can 'be regulated at will.

The operation and many adaptations of the herein-described power-transmitter are thought to be quite apparent, and it will be readily seen that the same can be used in connection with any other machinery to be driven as well as the grinding-mill illustrated. In order to insure greater efficiency in operation, a spring R. is'secured to the bottom of the reciprocating frame I and the bottom of the supporting-framework, so that a greater force will be given to the downward stroke of the windmill-rod and the operation of the transmitter greatly assisted.

Having thus described my invention, what I claim, and desire to .secure by Letters Pate.nt,is-
