FREDERICK W. HEDGELAND, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE W. W. KIMBALL COMPANY, OF SAME PLACE.
PNEUMATIC-MOTOR.
SPECIFICATION forming part of Letters Patent No. 593,655, dated November 16, 1897. Application filed May 10, 1897. Serial No. 635,853. (ITO model.)
To all whom it may concern.-
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 new and useful Improvement in Pneumatic-Motors, of which the following is a specification.
This invention relates to improvements in' horizontal section, and Fig. 4 is a transverse section on 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 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. The'number of sides, as well as the number of pneumatics, may be varied, however. The movable sides of the several pneumatics are each connected to a crank-pin 0 upon the pulley C by means of the links D and arms D, so that by successively inflating and deflating the pneumatics they will actuate said pulley and thereby create power in the latter,which may be transferred to the shaft tobe driven by any suitable belt. The pneumatics are all arranged with their axes parallel with the axis of the pulley.
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 pneumatic, 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'F and G, mounted upon the same stem and located one in the chamber A and the other in the chamber A and at the ports connecting those chambers with said passage E. The valves preferably move toward and from the pulley and parallel with its axis and act alternately to close and also to open said ports. They are shifted in one direction by the power of the suction existing in chamber A (this movement carrying them to the position shown at Fig. 3) and are moved in the opposite direction by the contact of extension H of the valve-stem with the cam J upon the side face of the pulley. The cam is adapted to act upon each of the valves for about one-half of the time. it is acting upon either pair of valves the pneumatic controlled by those valves becomes inflated and its deflation begins as soon as the cam has ceased to act upon its valves, so that the latter may then be shifted by the suction.
With the construction described the operation will be fully understood by those skilled in the art without further description.
The construction I have shown may obviously be varied in many ways without departing from the spirit of my invention, and hence I do not wish to be limited to the details shown.
By my invention I am enabled to dispense entirely with the rotating shaft and its bearings heretofore generally used and to mount the pulley upon a stud or pivot C which does not need to revolve. I also operate all the valves of the several pneumatics by the same cam instead of employing separate cams for each pneumatic. That portion of trunk A forming chamber A I employ as a matter of convenience for the proper support of the pneumatics. It has no efiect upon the movements of the air or of any moving part of the motor.
I claim- 1. The pneumatic-motor, consisting of a series of pneumatics, an exhaust-chamber common to all the pneumatics and around which they are arranged, a pulley driven by the pneumatics and supported upon an axis parallel with the axes of the pneumatics, a series of valves the stems whereof are parallel with the axes of the pneumatics, and a cam on the While mon to all the pneumatics and around which they are arranged, a pulley driven by the pneumatics and supported upon an axis pai allel with the axes of the pneumatics, a cam on the face of the pulley, and a series of valves actuated by the cam and controlling the pneuinatics, substantially as specified.
