UNITED STATES PATENT OFFICE.

- ALBERT LOWRY, OF MARSEILLES, ILLINOIS.

IMPROVMENT IN 4WINADMILLS.

Specification forming part of Letters Patent No. 173,552, dated February 15, 1876 application filed June 12, 1875.

To all whom it may concern Be it known vthat I, ALBERT LoWRY, of

Marseilles, in the county ot La Salle and State -of Illinois, have invented a new and Improved Amodification. of swivel-connection of wheelsections and arms; and Figs. 5 and 6, front View and section of the pump-rod eccentric.

Similar letters ot' reference indicate corresponding parts.

The invention will first be described in connection with drawing, and then pointed out in the claims.

In the drawing, A represents the supporting frame or standards of my improved windmill, which carry the turn-table B. The wheelshaft C revolves in beari n gs ofthe top part of the turn-table, and carries at the front end the metallic spider-frame D, having radial extension-arms D', to the ends of which are swiveled, by blocks and balls D2, as shown in Figs. 3 and 4, the swinging wheel-sections E. The lateral swivel-arms a of the wheel-sections E 'are connected by pivoted rods and bell-crank levers d, fulcrumed to the circumference of the spider-frame I), with the slide-head F, that is guided in rectilinear directionv 011 the Wheelshai't, but revolved atthe same time with the shaft. A brake-collar, F', is fitted to an annular groove'oi' slide-head F, and attached to the ends of the brake-stirrup G, that slidesin uniform speed of the Wheel, at varying velocities of the Wind, is obtained.

The power is transmitted from the wheelshaft by a bevel-wheel, h, to a double bevelwheel, h1, placed inside of the housed turntable, and gearing with a bevel-wheel, h2, of an intermediate shaft, h3, from which, by pnlleys and chain or belt, the horizontal drivingshaft I is set in motion.

Shaft I works by an adjustable eccentric,

L, with circumEerentially-iitted slide-ring L',

the pump-rod, or any other machinery that may be connected thereto.

The stroke of the`pumprod may be regulated by adjusting tlle eccentric'to greater or less eccentricity on the shaft, as shown in detail in Figs. 5 and 6.

The governing-vane M, attached to the rear end of the wheel-shaft, holds the wheel, in connectiQn with the turn-table, against the wind, while adjustable governing-weights a' of the swiveled wheel-sections adjust the motion of the same in the wind, producing a Windmill of regular and reliable Workingcapacity.

I am aware of the patents granted to Mabie and Little, dated, respectively, May 2,1871, and April 2, 1872, and I therefore fully disclaim the same, and confine my invention to the particular construction shown and described.

' Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the wheel-sections E, swivel-arms a, rods b, bell-cranks d, slide-head F, having annular groove, brake-collar F', stirrup G, guides e j', support H', lever H, spring g, and stop g', substantially as described, and for the purpose specified.

2. The combination of the wheel-shaft, carrying bevel-wheel 7L, with the double bevelwheel h1, contained in the housed turn-table, the wheel h2., and the chain-gear, as and for the purpose described.

3. The combination of the radial wheelarms, having swivel-sockets D2, with the arm a, having pivots fitting therein, and the wheelsections E, having adjustable weights a', substantially as and for the purpose described.
