JAMES DEVINE, OF SPRINGFIELD, MASSACHUSETTS.
SPECIFICATION forming part ofLetters Patent No. 732,341, dated June 30, 1903.
Application filed July 11, 1902. Serial No. 115,186. (No model.)
T0 at whom itamty concern: Be it known that'I, JAMES DEVINE, acitizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvementsin Oscillatory Supports forFans or other Objects,
of which thefollowing is a full, clear, and eX-- An aim of the invention is to provide a mechanism which shall be comparatively simple in construction and not liable to become deranged after protracted use and one in which the motion may be regular and uniform at all times.
The invention consists in constructions and combinations of parts, all substantially as hereinafter fully described, and set forth in the claims.
The oscillatory platform and the mechanism for imparting its movements thereto are illustrated in the accompanying drawings, in which f Figure 1 is'a horizontal sectional view and plan of the parts below the plane of section. Fig. 2 is a central vertical section taken on the line 2 2, Fig. 1. Fig. 2 represents the plane of the horizontal section on whichFig. 1 is taken.
Similar characters of reference indicate corresponding parts in both of the views.
In the drawings, A represents a circular casing mounted on a suitable base, at the top of which the circular platform or plate B is mounted for its oscillatory movement in a plane at right angles to the common axis of itself and the casing. The upper portion of the casing has an inwardly-extending annular flange a, having the ball race or groove 19 for the balls 0, upon which the support B has antifrictional bearing. A shaft C is mounted axially and fixed within the casing and forms The section-line 1 1 on the central bearing for various of the parts concentrically arranged thereabout.
A sleeve D is fixed to the center of the platform B and depends therebelow and has thereon the gear-wheel E, with which meshes the teeth of a sector-gearF, which is mountedfor its oscillatory movement on the stud d, affixed to and depending belowthe aforementioned flange aof the casing. One of thelaterally-extended portions of the sectorgear has a depending'studf, which engages in the groove 9 of the heart-shaped cam G. The cam has a continuous rotary motion imparted to it primarily from the reaction of the clockspring H,oneend hof whichis affixed to the side of the casing, while its inner end within its several convolutions is affixed to a sleeve t,
which loosely surrounds another sleeve j, ro-
tatable about the central shaft 0, and on which latter sleeve j the hub'of the cam G is fixed.
The aforementioned sleeve '5 has attached thereto the ratchet-wheel k and has loose thereon at its lower end the gear-wheel m, and dog or pawl m which is pivoted on the gear-wheel m, is in spring engagement with the teeth of the ratchet-wheel k, and the aforementioned sleeve j has a pinion gearwheel n, with which meshes a large gear- Wheel 0, which latter has as a part thereof the pinion 0 which gears back into the gearwheel on, and-the outer sleeve 1: above the clock-spring has the large gear-wheelp affixed thereto, with which engages the pinion g on p the winding-shaft'qi which is adapted at its end q? to receive a winding-key.
It will be apparent that through the key and shaft g the gear 19 will be rotated and with it the sleeve 2', thereby rotating the ratchet-Wheel, which may turn in one directionindependently of the gearing m n 0 0 the connection between the sleeve t' and the spring winding up said spring, which latter is held in its wound condition by the pawl or dog,'to unwind only by reacting through the dogged ratchet wheel, and gearing at the bottom to impart a slow rotary motion to the cam G and through such continuous rotary motion of the cam to impart an oscillatory ICO motion to the sector-gear and an oscillatory motion to the support or platform B.
As a means for insuring steady movements of the oscillatory platform or support 13 as imparted thereto by the spring-power through the gearing connections described a governing or regulating device is cooperatively combined in the mechanism. the same consisting of a cup-shaped casing J, having concentrically therewithin a stud i, on or with which rotates a lantern-pinion to, having radial arms 11, 16*, to which are pivotally connected centrifugal blocks 1) r, the arc-shaped outer edges of which are adapted to bear frictionally on the inner surface of the wallof the cup-shaped casing J. The springs ware applied between the centrifugal blocks and the aforementioned arms 0 which have reaction tending to draw the blocks away from their rim-bearings.
A rotation of the lantern-pinion and the centrifugal blocks which is speedy in comparison with the rotational movement of the sector gearing and support B is imparted by constituting the base of the cam G of large diameter and circular form and cut with gearteeth as to engage in the lantern-pinion. The diameter of the gear being many times that of the pinion u, the rotations of the latter in the ordinary running down of the clockspring mechanism will develop such speed as to cause the blocks to work frictionally against the rim of the casing therefor, the tension of the springs being adjusted for the desired regulating effect.
While the mechanism for the purpose described may in accordance with this invention be varied considerably in the matter of detail without departure from the essence and spirit of the invention, it is to be pointed out that the arrangement shown is one wherein the number of necessary parts are reduced to a minimum and wherein the assemblage may be quickly and easily performed.
