POWER-TRANSMITTER.
' SPECIFICATION forming part of Letters Patent No. 466,352, dated January 5,1892.
Application filed October 10,1891. Serial No. 408,310. on model.)
Be it known that I, ALBERTLEWIs, a citizen of the United States, residing at Marshalltown, in the county of Marshall and State of Iowa, have invented a new and useful Power-Transmitter, of which the following is a specification.
My invention relates to power-transmitters, and more especially to that class of devices used in connection with windmills; but it is also designed to be used in connection with any machine or mechanical movement in which it is desired to convert rotary into reciprocating motion; and the invention has for its object to provide apower-transmitterwhich will be simple in construction and eifective in operation to attain its main object to accomplish an increased length of stroke for the With these and other objects in view,which will be readily apparent as the nature of the device is better understood, the invention consists in the novel mechanical movement hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the'appended claims.
In the accompanying drawings, Figure 1 is an inner elevation of the upper portion of a windmill, the tower and supports not shown. Fig. 2 is a detail in perspective of the upper portion of the'windmill-casting provided with a power-transmitter.constructed in accordnary tubular casting usually employed with V i... a
vertical wind-wheels, and is provided at its extreme upper limit with the brackets or arms B, by which the same is supported within and upon the ordinary windmill-tower, which, being of the usual type, is not illustrated in the drawings, and said casting is also provided with the upper horizontal bearing 0, within which is journaled the wind-wheel shaft'D, carrying upon its outer end an ordinary ver tical wind-wheel E, while upon its inner end is mounted the circular plate or disk F,which is ordinarily employed as the crank-plate,with which the pitman is connected with the pumprod. Upon the outer face of said plate ordisk and also carried by the wheel-shaft D is the pinion G, provided with the central projection or arm g, upon which is journaled the friction-wheel g, the function of which will be presently described.
The power-transmitting pitinan H is pivotally secured at its lower end to the sliding nates in an enlarged head K, which is pro-- vided with an oblong slot having curved ends and having an inner toothed surface 70 that is designed to be engaged by the pinion G, carried upon the inner end of the wheelshaft. The side of the enlarged head K adjacent to the plate or disk F is provided with an encircling flange 70 projecting inwardly and beyond the edges of the teeth, and which is designed to take between said pinion and the plate or disk F as the pinion travels around the toothed surface or edgesof said pitmanhead, thus serving to hold the head in 'position upon the face of said plate or disk and the pinion G in mesh therewith. Extending longitudinally over the slot in the pitmanhead and raised above the plane thereof is the guide-bar L, provided with the inwardly projecting guide-rib Z, that extends inwardly a sufficient distance and is of such length as to permit the friction-roller g, carried by the pinion G, to travel upon both sides of the same and over each end thereof as the Wheelshaft carries said pinion up and down each side of the toothed surface of said slot to cause a reciprocation of the pitman-arm.
It can be readily seen from the foregoing that as the wheel-shaft D revolves the pinion G, meshing with the teeth in the oblong slot, will be held into engagement upon one vside thereof as the same is either traveling in an upward or downward direction by said guide-rib engaging the friction-roller g the opposite side of the same to hold the pinion in mesh with the teeth upon the opposite side of said slot, thus giving the pitman a longer stroke than is usual in devices of this character. The same result is accomplished by a slight modification, as illustrated in Fig. 4 of the drawings. In this construction, instead of having theinner surface of theoblong slot toothed, as described, the same has a smooth bearing-surface, which forms a guide for the roller N,-Which supplants the pinion, While the friction-roller g is dispensed with and a small pinion O is used in lieu thereof and is designed to engage the toothed sides P of the rib Z previously described. It can be seen that this modification, which is of but slightlydilferent construction, still retains the principles of my invention and accomplishes the same result in practically the same manner Without departing from the spirit thereof.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a power-transmitter, the combination, with a rotary shaft having a circular flange or disk upon one end, of the pinion carried by said shaft upon the face of said disk and provided with a central projection carrying a friction-roller, the pitman-arm having an oblong slotted head at one end, having an inner toothed surface and working over the face of said flange or disk, and a guide-rib secured longitudinally of said slot and adapted to engage the friction-roller of said pinion and hold the same alternately in mesh with the opposite toothed sides of said slot, substantially as set forth.
2. In apower-transmitter, the combination, with a rotary shaft having a circular flange or disk upon one end, of the pinion carried by said shaft upon the face of said disk and provided with a central projection carrying a friction-roller, the pitman-arm having an oblong slotted head at one end, said slot be ing provided with curved ends and an inner toothed surface, an inwardly-projecting and encircling flange adapted to take between said pinion and said disk, and a guide-bar secured longitudinally of said slot and provided with the inwardly-projecting guide-rib projecting within said slot and adapted toengage said friction-roller and hold said pinion in mesh withthe opposite toothed sides and ends of said slot, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
