MECHANISM FOR CONVERTING MOTION.
SPEGIFICATIONfQI-ming m of Letters Patent'No. 700,363, dated May 20, 1902.
Applicationfiledhugust1,1901. SeIial Il'oJOAM. (NomoclelJ T 0 all ibhom it may concern;
Be it known that I, MOSES O. NIXON,v of the city of Fort Wayne, in the'county of'Allen and State of Indiana, have invented certain new: and useful Improvements in Mechanismforf Converting Rotary Motion into Reciprocating Motion, Particularly Suitable for WVin'dmills, of which the following isa specification.
The object of my invention is to devise mechanism of the class described which will perform the work with the least maximum power or at varying speeds. In the case of windmills it is desired to make the mill operate with comparatively light winds. Hence as the downward stroke of thepump plunger rod of the windmill is assistedby the weight of the parts and the upward stroke retarded it is necessary to makethe upward stroke slower than the downward stroke to equalize the power required, so that the mill will operate with the least maximum wind-pressure. I attain this object by the combination of parts hereinafter more specifically described.
and then definitely claimed.
Figure 1 is a side elevation, partly'broken away, of my improved mechanism. Fig. 2 is a plan view of the same.
In the drawings like letters of reference indicate corresponding parts in the different figures.
A is the mainframe of the mechanism, suitably shaped to support the difierent parts.
Pivoted on this frame at a is a movable or' swinging frame B.
It will be noticed that an extra pivot-bearing a is provided in the main frame A for the pivot a of the movable frame B, so that the length of stroke of the mechanism may be varied at will.
Journaled in the main frame A, which may be of any suitable construction, according to the purpose for which the movement is used, is a shaft 0, to which is rigidly secured the gear-pinion D. This pinion meshes with the gear-wheel E, secured to the shaft F, journaled in the main frame A. Secured to this shaft is a doublejcam or two cams G and H side by side. Above the cam G on the movable frame B is journaled a roller I, and on the same frame below the cam H is journaled the roller J.
The sides of the movable frame B at its jouterfe'nd are connected by the cross-bar b. On this cross-bar, is pivotedfthe plunger-rod K,adapted to work thr ughasuitableopen- ;'ing in the frame A. i
' Thec'ams G and H areso shaped and proportionedthat the movable frame B will be- ;lifted comparatively slowly-[and with invcreased'pow'er and, after thehighest point has been reachedwill be'dropped comparatively rapidly to the lowest position. As the weight of the plunger-rod assists the power .on the downward stroke and acts against fthe power on the upward stroke, it is evident that less power is required to force the plun- Hence less ger downward than to raise it. power is required anda morerapid speed is possible on the downstroke than on the upstroke. The demand on the'power of a windmill is thus equalized by constructing the cams as already described, enabling it to perform the work with less maximum power or windthanby other devices.
1 While the cams, as shown, are so shaped that the cam G is always in contact with the 'roller I and the cam H inlcontact with the roller J making the motion of the mecha'nism positive atall times, yet it is not the intention to limit the invention to this exact construction.v
The power of the windmill is applied to the shaft 0 in any suitable manner, and the comparatively rapid motion of the windmill is jsloweddown and the power increased by the small pinion D, meshing with the large gearwheel E on the shaft carrying the operatingcams.
I prefer to pivot the movable frame as shown, thoughother arrangementsiniglit be adopted which would permit of its reciprocating motion under the action of the cams GrandI-I.
Although this mechanism is particularly adapted for windmills, yet it may be readily applied to other'purposes, and it is notthein tention to limit the invention to that particular use.
It is of course understood that the terms lifted and dropped, up and down, and the like are only used relatively, as the mechanism maybe used in other positions thanjthe vertical.
What I claim as my invention isp 1.
