MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 390,976, dated October 9, 1888.

Application filed June 19, 1888.

.To all whom t may concern/f Be it known that I, JAMns W. KINCAID, a citizen of the United States of America, residing at Georgetown, in the county of Villiamson and State of Texas, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in mechanical movements, having for its object the provision of improved and highly efficient means for converting the reciprocal movement of a windinill-shaft to a rotary motion of a horizontallydisposed shaft.

The invention, therefore, comprises the peculiar construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claim.

ln the accompanying` drawings, Figure 1 is a rear elevation of my improved mechanical movement or motion-converter. Fig. 2 is a detail perspective view thereof.

Referring to the drawings, A designates a post or upright, wherein is supported one end of a horizontallydisposed shaft, a, upon the end of which is secured apinion, a, having curved teeth, as shown. Upon this shaft is secured a balance-wheel, to regulate or balance said shaft in its movement.

Bis asliding block or frame designed to move in gnideways I) b, formed in the rear side of the post or upright A, and to this block or frame is connected the lower end of the pitman (not shown) of the windmill to which it is attached. To the lower opposite corners of this block or frame B are pivotally connected the upper ends of two vertically-disposed rack-bars, C C', connected together at their lower ends bya Serial No. 277,578. (No model.)

spiral or coil spring, d, as shown. The teeth of these hanging rack-bars C C project in opposite direct-ions, those of the rack-bar C being projected upwardly, while those of the rackhar C project downwardly, as shown. The ,object of this arrangement is that the teeth of the rack-bar C will engage the curved teeth of the pinion a only in its upward movement, while the teeth of the rack-bar C will engage 5o said teeth ofthe pinion only in its downward movement.

From this it will be seen that the teeth of both rack-hars are always held in contact with the teeth of the pinion, and that the teeth of each raclcioar will alternately mesh with the teeth of said pinion, whereby the reciprocal motion imparted to said rack-bars willimpart a continuons rotary motion to the shaft a, the teeth of the bar not meshing with the pinion 6o readily riding over said teeth, as is obvious.

My invention is extremely simple, and by means thereof the motion of a windmill is readily and easily imparted to a revolving shaft, whereby power is obtained for driving or operating machinery, or for'any other purpose.

I claim as my inventionrlhe combination, with the vertical post or upright having gnideways formed therein,and the horizontallydisposed shaft having the pin- 7o ion secured thereon, of the slidable block or frame, the rack-bars pivotally secured to the lower end thereof and having oppositely-projecting teeth, and the spring connected to the lower ends of said rack-bars, substantially as shown and described.

In testimony whereof Iaflix my signature in presence of two witnesses.

JAMES V. KINCAD.
