IMPROVEMENT'IN DEVICES FOR TRANSMITTING MOTION.

Specification forming part of Letters Patent No. 210,469, dated December 3, 1878; application filed September 26, 1878.

To all whom 'it may concern:

Be it known that I, GEORGE E. RUSSELL, of Cheyenne, in the county of Laramie and Territory of Wyoming, have invented a new and Improved Device for Transmitting Motion, of which the following is a specification:

'ln the accompanying drawing, Figure 1 represents a front view, partly in section, of my improved device for transmitting motion, shown as applied to a windmill. Fig. 2 is a side view of the same; Fig. 3, a detail horizontal section on line 00 m, Fig. 1, of the slid-. ing sections of the transmitting-shaft; and Fig. 4, a detail horizontal section and top view of the shaft-sections and cross-heads on line 3 3 Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention refers to an improved device for transmitting motion, the device being especially adapted for windmills, so that the rotary motion of the wheel-shaft is transmitted in a steady, even, and noiseless manner, whatever he the position of the wheel, and either a rotary or reciprocating motion imparted to the machines, pumps, or other appliances to be driven thereby.

The device works with little friction, has no dead-centers, and is very'durable, as it has noweak parts that are liable to break.

Referring to the drawings, A represents the supporting-mast, and B the turn-table, of a windmill. The shaft 0 of the wind-wheel turns in bearings of the turn-table, and is'provided with two cranks, G, at right angles to each other. The cranks 0 connect by short pitman D with a split perpendicular shaft, E, whose semicircular rods slide up and down alongside, but independently of, each other. The lower ends of the semicircular shaft-rods are attached to separate cross-heads E, the rod connecting with the crank next to the wind-wheel being attached by shoulders or otherwise to the upper cross-head, while the other rod passes through the center of the upper cross-head, andtis secured to the lower cross-head. Both rods are so attached to the cross-heads as to be firmly secured in a longitudinal direction, but admit the free axial turning therein, so as to follow the motion of the turn-table and wind-wheel. The center of the lower end of the rod, attached to the lower cross-head, forms also the center of the split shaft, and is the axis on which the turntable, the wind-wheel, the upper connectingpitman, and the split shaft rotate to accom modate the wind-wheel to the wind.

The split shaft E is kept in position and guided at the upper part by a brass shoe, B, which is attached to the revolving portion of the turn-table. Any other guide or device may, however, be used when the transmitting mechanism is applied to other constructions of windmills, or to any other shaft. The two cross-heads are held in position and slide on two guide-rods, which are fastened by a bed-plate to the mast A. Each crosshead E is again connected by pitmen F with similar cranks F of a lower horizontal shaft,

F by which rotary motion is imparted to the same. The lower shaft, F turns in boxes lined with Babbitt metal, the boxes being at tached to a head-block, which is also fastened to the mast.

The motion of the difierent parts is steady and noiseless, owing to the sliding motion of the same and the absence of cog -wheels. There is very little friction between the shaft rods, as the same are kept apart by shoul ders or faces a near the upper and lower ends. By the rectangular position of the cranks dead'centers are avoided and the motion equalized.

The rotary motion of the lower shaft may be transmitted in any suitable manner to the machinery to be driven. To the lower shaft may be again applied another double crank, in a reverse position to each other. To these reverse cranks may be attached two pis= ton-rods, which are extended downward to a double-cylinder pump. One of the pistons moves upward while the other moves downward, so that they throw a continuous stream of water, and utilize the entire revolution of the wind-wheel, discharging twice the quan tity of water raised bythe common single crank and rod.

The motion of the wind-wheel shaft-is thus transmitted and effectively utilized without interfering with-the wheel or vane or their method of rotating, whether on a turn-table D E, the cross-bars E, and the split perpenor otherwise. dicular shaft E, guided in a shoe, B, the lat- Ha-vin-g thus described my i11vcntion,I claim ter shaft being composed of two independent as new and desire to secure by Letters Patslide-rods, as and for the purpose specified.
