WIND-MOTOR.

SPECIFICATION forming part of Letters Patent No. 591,21 8, dated October 5, 1897. Applicatitn filed May 10,1897. Seria1No.635,852. (NomodeL) To all whom it may oncern:

Be it known that I, FREDERICK W. HEDGE- LAND, a citizen of the United States, residing in Chicago, in the county 'of Cook and State of Illinois, have invented a newanduseful Improvement in YVind-Motors, of which the following is a specification.

This invention relates to improvements in wind-motors. It has been devised more especially for use in operating the tremolos and music-sheets of organs; and its leadingobject is the obviating of the friction present in previous constructions.

The nature of the improvement is fully set forth below and is illustrated in the accompanying drawings, in which- Figure 1 is a side and'Fig 2 is an end elevation of the invention. Fig. 3 is a longitudinal section; and Fig. 4, a transverse sect-ion, the latter upon the line 4 4 of-Fig. 3.

In said drawings, A represents a box, chest, or trunk divided interiorly by the partition A into two chambers A and A I The former of these chambers communicates" with the air by the opening A, which is constantly open, and the latter is constantly exhausted of air by the bellows or other wind-producing devices, being connected therewith by one or more ducts A The trunk is preferably three-sided, and the pneumatics B are placed one at each side. well as the number of pneumatics may be varied, however. The movable sides of the several pneumatics are each connectedto a crank-pin 0 upon the pulley O by means of the links D and arms I), so that by successively inflating and deflating the pneumatics they will actuate said pulley, andv thereby create power in the latter which may be trans ferred to the shaft, which is to be driven by any suitable belt. The pneumatics are supplied with the air necessary for inflation from the chamber A by means of passages E, of

which there is one leading from each pneu- 1natic,and each of such passages also connects with'chamber A so that the deflation may take place into that chamber. These movements of the air are controlled by valves The number of sides as.

ing those chambers with said passage E. Each pair of the valves F and Gr is connected by means of their stem with a membrane-motor H, located in the wall of chamber A and having an air-passage H in its rear, communicating both with the outer air by duct H and with chambe'r'A by ports guarded by valves H and Hflmounted upon a common stem H and adapted to open and also to close the ports alternately. These latter valves are operated automatically by their corresponding pneumatics at the close of each expansion, and also at the close of each collapse of the pneumatic by means of a lever J, located in the pneumatic, as shown, and rocking upon a pivot J ,the lever being positively attached at one end to the stem of the valves and receiving power at its other end from the moving side of the pneumatic through the medium of a tension device K, secured in said moving side and passing freely through the lever with a button below the same, so that it will pull upon the lever just before the conclusion of the expanding movement of the pneumatic, and a stop K is also carried by said moving side and adapted to depress the lever as the moving side nears its completelyexhausted position. Both the devices K and K may be adjustable, so they may be regulated as to the timeof their action and the extent of movement imparted by them.

In the position shown at Fig. 3 the lower pneumatic is shown as fully expanded and the valvesF G as shifted ready to permit deflating, the valve II being also open and valve H closed, so that the motor-passage H may also be exhausted. The main valves F G are moved to this position by the suction power existing in chamber Aiacting upon valve G, the membrane-motor b'eing neutralized at the time by the fact that like conditions prevail upon both sides of it, and the valves H and II have been shifted to the location shown by the lever J when last actuated by the connection K. Deflation now ensues and collapses the pneumatic and re verses the lever J by means of stop K, and in so doing the valves H and H4 are also reversed, so that the air flows through duct H into passage H and inflates motor H, causing such pressure on the latter as will shift its moving side again carries lever J to the position in said figure. This closes valve H, opens valve H allows the exhaust to draw air from behind membrane H, so as to neutralize said membrane, and the suction then shifts valves F and G back to the position illustrated.

One great advantage of my invention is that it has so few points at which friction exists, and to still further decrease the friction 1 provide the belt-pulley O with a ball-bearing, the supporting stud or pivot C being grooved, as shown, so as to form two oppositefaced cones, and the interior of the pulley being provided with cups 0 at opposite sides. The balls C are by this construction confined at both sides, and a bearing is formed which is not only very durable and requires no lubricating, but is also noiseless.

My invent-ion is in no wise dependent upon the number of sides or the number of pneumatics, nor upon the arrangement of the pneumatics around the chamber or trunk, nor to the use of a pulley mounted upon a stud instead of long shaft, nor to the connecting of the pneumatics directly tojthe driven pulley.

I claim- 1. The combination in a pneumatic-motor, of a series of pneumatics, a series of valves corresponding to the pneumatics and acting to control the inflating and deflating thereof, and means whereby each pneumatic, independently of the other pneumatics, is enabled to control its own valves, substantially as specified.

2. The combination in a pneumatic-motor, of a series of pneumatics, a series of valves corresponding to the pneumatics and acting to control the inflating and deflating thereof, and a separate motor device in the case of each pneumatic for operating said valves,

such motor device being under the independent control of the movable side of the corresponding pneumatic, substantially as specified.

3. The pneumatic-motor, wherein are combined a series of pneumatics B, and their controlling-valves, each pneumatic being provided with means whereby it may, independently of all the other pneumatics, control its own valves, substantially as specified.

4. The combination with a pulley or other rotating device, of a wind-motor for driving the same, said motor containing a series of pneumatics, valves controlling said pneumatics, and means whereby each pneumatic may, independently of the other pneumatics, operate its own valves, substantially as specified.

5. The combination in a pneumatic-motor, of a series of power-pneumatics B, a windchamber, valves controlling the passages between the chamber and the pneumatics, a separate lever for each pneumatic actuated by the moving side thereof,and devices whereby each of said levers controls the valves of its own pneumatic, substantially as specified.

6. The wind-motor, consisting of a series of pneumatics arranged around a wind-chest, valves for each pneumatic controlling the inflating and deflating thereof, a membranemotor for shifting the valves of each pneumatic, and a lever adjacent to and actuated by the moving side of each pneumatic, and serving to cause the operation of the membrane-motor of the same pneumatic, substantially as specified.

7. The pneumatic-motor, consistin'gof a series of pneumatics, each provided with separate valves, and each having its movable side connected to and controlling its own valves by means of connections independent of the other pneumatics, substantially as specified.
