POWER-TRANSMITTING DEVICE.
SPECIFICATION forming part of Letters Patent No. 681,116, dated August 20, 1901.
Application filed October 25, 1900. Serial No. 34,349. (No model.)
To @ZZ whom, it' may concorre:
4Be it known that I, FEEEMAGRANT, a citizen of the United States, residing at Stoning- Y tinfrdevicesin reneral and more articular] to a device for converting reciprocatory motion into rotary motion, and the principles involved may be employed in connection with any style of reciprocatory fluid-pressure engine, the object of the invention being to provide asimple and efficient construction wherein it will be impossible for the engine to get ou a`dead-center and wherein the leverage will be approximately constant.
Further objects and advantages of the invention will be apparent from the following description.
reference indicate similar parts in the several views, Figure l is a side elevation showing the pawl-carrying frame, with the plates removed at one side to show the positions of the pawls with respect to the ratchet. Fig. 2
is a longitudinal section of the head of the piston-rod, taken in a plane above the rod andthe engine-shaft and showing thedisposition of the driving-ratchet with respect to the engaging-pawl frame.
` Referring nowtothedrawings, 5 represents' the cylinder of a reciprocatory steam-engine, inwhiclris a piston Ahaving a projecting rod 6, which is adapted for reciprocation under the influence of steam admitted alternately to the ends of the cylinder in the usual and Well-known manner, the cut-o mechanism, of usual construction, being operated by engagement of fingers 7 and Supon the pistonrod, with astop 9 upon the valve-rod 10. The outer end of the piston-rod instead of having the usual cross-head attached thereto and operating in guides has attached to its outer end a frame. This frame comprises"` end plates 11 and 12, at the ends of which project flanges 13, laterally in pairs, and connecting the corresponding flanges of the end plates are side plates 14, which are oppositely disposed in pairs, each pair of side plates "forming a guideway, so that two guideways are formed, one at each side of the frame.
Upon the inner face of each plate 14L are formed diagonal flanges or ribs 15, the flanges of each pair of plates lying parallel, and at the o uter end of each of these anges is formed a shoulder 16, having a curvilinear recess in its face in which is seated the curvilinear end of a pawl 17, which is held pivotally i'n place. These 'pawls 17 are held norinallyito lie flat against the flanges l5 by means of coilsprings, as shown, the extremities of the pawls being thus held normally engaged with the teeth of a ratchet-wheel 18, which is fixed upon the engine-shaft 19. The pawls being disposed in oppositev directions at the two sides of the frame, it naturally follows that when the frame is moved in one direction one set of pawls successively engage the ratchetwheel operatively and rotate it,while the other series of pawls snap idly over the ratchetteeth, the former idle teeth being operative and the former active teeth being inoperative when the direction of movement of the frame is reversed. By the formation and arrange ment of the flanges and the shoulders at the bases thereof the strain is taken from the pivots of the pawls, so that a structure of great strength is obtained.
As shown in the drawings, the side plates may be adjustably connected with the end plates of the frame, so that the two series of pawls may be moved toward and away from each other,and thus when itis desired to rotate the engine-shaft at a greater or lesser speed, with a constant speed of reciprocation of the pistou-rod, a smaller or larger ratchet-wheel may be secured upon the engine-shaft, and the side plates of the frame may be adjusted to properly engage the pawls with the substituted ratchet-Wheel.
It will of course be understood that in practice various modifications of the construction shown may be made and that` any suitable materials and proportions may be used for the various parts thereof without departing from the spirit of the invention.
What is claimed is- IOO l. Inadevice of the class described, v`the combination with the reciprocating frod and shaft, of a frame comprising side portions having gnideways, pawls pivotally mounted in' the guideways, the pawls at opposite sides of the frame being disposed oppositely,-anda ratchet-Wheel xed upon the shaft and lying with its periphery in operative relation to the pawls.
2. In a device of the class described, the combination with the reciprocating rod and shaft, of a frame comprising side portion-s adj nstahle Vtoward and away from each other, pawls pivoted upon the side plates and ad` linstable therewith, and a ratchet removably disposed upon the shaft in operative'relation to the pawls, said shaft `beingadapted toreceive -ratche'ts of different diameters interchangeably.
3. Ina device of the class described, the combination with the reciprocating rod and shaft, a ratchet removably engaged with the shaft to permit of substitution of a ratchet of different diameter, and a frame fixed to the rod, said frame comprising side plates disposed in pairs, and pawls pivoted between the pairs of plates in operative relation to the ratchets'opposite1y, said pairs of side plates
