Specification of Letters Patent.

"Patented June 24, 1913.

To all whom it may concern:

Be it known that I, IGNAC BASINSKI, a subject of the Emperor of Austria-Hungary,

residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Compressed-Air Motors, of which the following is a specification, reference being had therewhere easy access cannot behad to a source ofgelfl triqityiorpther sour eof po er? A-further ofoject Of 'thlS invention is a} provide a'motor wherein a series of, air cylinders are employed for imparting a con tinuous rotar movement to a drive shaft.

With the a ve and other objects'in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein Figure 1 is a plan of a motor in accordance with this invention, Fig; 2 is a side elevation of the same, Fig. 3 is a longitudinal sectional view of a portion of themotor, Fig. 4 is a cross sectional view ofthe same, and Fig; 5' is a detail sectional view of one of the air cylinders.

The reference numeral 1 denotes a foundation frame, rectangular in plan and provided with corner pieces 2 and 3 connected by longitudinal girders 4.

Mounted upon the foundation frame 1, between the posts 3, is a large metallic cylinder or tank 5" that has an air inlet pipe 6 communicating with a source of air Suppl provided with a globe valve 7 of the ordinary and well known type. An air pump can be connected to the pipe 6 to pump air into the tank 5 and compress the same therein, the pressure of air within the tank 5 being ascertained by a pressure gage 8 connected to the tank 5, adjacent to the top thereof, said gage being of a conventional form.

Arranged upon the foundation frame 1 are transverse bed plates 9 and 10 and mounted upon the former are curved frames 11 having the upper ends thereof connected to the girders 4 and intermediate the ends provided with guides 12. Mounted upon the bed plate 9, beneath the guides 12, are cylinders 13 that have the lower ends thereof connected by pipes 14 to the tank 5, said pipes being in communication with the tank adjacent to the upper end thereof. The pipes 14 have valves 15 of a conventional form that permit of the sup 1y of air to the cylinders. 13 being shut 05 or regulated. One of the cylinders 13 is illustrated in detail in Fig. 5 of the drawings. The cylinder has a piston rod-16, a piston 17, a cylindrical valve casing 18, a valve 19 slidably mounted in said casing and connected to the ,piston rod 16 by a stem 20. The valve 19 closes a port 21 in the lower end of the cylinder-13 during an upstroke of the piston rod 16, and the port 21 is uncovered during a down stroke of the piston rod to allow air to exhaust from thecylinder. Located upon the pipes 14 are check valves 22 of a conventional form that shut off the supply of' air to the cylinders 13 during a down stroke of the piston rod 16.

The piston rods 16 are provided with pitmen 23 and 24. The pitmen 23 are pivot- ;ally' connected to cranks 25 of. ashaft 26,

journaled in bearings 27,- carried by the girders 4. The pitinen 24 are connected to eccentrics 28 carried by the shaft 27,- adjacent'to the cranks 25.' The shaft 26, intermediate the ends thereof, has a sprocket wheel-29, and the ends of the shaft are provide'd with balance wheels 3(" Mounted upon the bed plate 10 are vertical posts 31 having brackets 32 supporting .a transverse auxiliary tank or cylinder 33.

This tank or cylinder is connected to the main tank or cylinder 5 by a pipe 34, said pipe having a globe valve 35and a check valve 36, both of which are of a conventional form, the latter being of that type that can be set either in an active position or in an inactive position.

Mounted upon the bed plate 10 are cylinders 37 and 38 similar to the cylinders 13. The cylinders 37 are connected to the auxiliary tank 33 by pipes 39 and the cylinders 38 by pipes 40, said pipes having check valves 41 similar to the valves 36. V

The cylinders 37 and 38 have piston rods 42 and 43 respectively, said piston rods having the up er ends thereof pivotally connected by links 44' and'45 to arms 46 fulcrumed upon the upper ends'of posts 47 mounted upon the bed plate 10. {The upper pivoted ends of the links 44 are pivotally.

connected-by pitrnen48. to -levers 4= 9 and 50. These levers' ar'e ivotally mou ed, as at 60 in the upper ends of the posts" 1 andsaid levers are provided with pitmen 61 that are connected to alternately arranged crank portions 62'of a shaft 63, journaled in bearings 64, carried bythe girders 4. The shaft 63 alternate with the cylinders 38 in transmitting power to the shaft 63, the cylinders 37 taking air from the auxiliary tank 33 while the cylinders '38 are exhausting and vice versa. This is also true in connection with the cylinders 13 and all of said cylinders cooperate in transmitting power to the shafts 26 and 63, the shafts operating in unison throughthe medium of the endless sprocket chain 67.

After the main tank 5 has been exhausted, it can be recharged, and the tank is of suiiicient size to permit of the motor being operated for a long period of time without recharging, it of course being understood that the exhaust .of air from the main tank depends upon the load to which the machine is subjected.-

When the tank 5 is charged, the tank 33 is also charged in View of the fact that the valve 35 is opened. In some instances but one set of cylinders is employed to drive both shafts, if so the tank 5 or the tank 33 is closed to that set of cylinders which communicate therewith. When both sets of cylinders are used they are open to their tanks for the supply of air. When the cylinders 37 and 38 are in communication with the tank 83, the latter is in communication ifoe aaaa with the tank 5 but the latter is closed to the cylinders 13 if these are not to be utilized, if utilized they are open to the tank 5. It is of course understood that when the load to which the machine is subjected is great, vthen both sets of cylinders are utilized, but when the load is light only one set of cylinders is en'lployed. What I claim -is:

1. In an air motor, the combination of a 'main tank provided with valved means adapted to communicate with a compressed air supply, a pair of shafts, a drive connection between said shafts, an auxiliary tank having a valved supply means communicating with said main tank, a pair of alterinately operating fluid pressure operated devices having valved connections with said main tank, a drive connection with one of said shafts, a pair of alternately operated fluid pressure operating devices having valved supply connections with said auxiliary tank and drive connections with the other of said shafts, said shafts arranged above said tanks and devices, and support ing means for said shafts.

2. In an air motor, the combination of a main tank provided with valved means for establishing communication with a compressed air supply, a pair of shafts and a drive connection between said shafts, an auxiliary tank having a valved supply connection with said main tank, a pair of alternately operating fluid pressure operated devices having valved connections with said main tank and a drive connection with one of said shafts, a pair of alternately operat-
