To (121 whom it may concern:

Be it known that I, THOMAS J. Lor'rUs,

. a citizen of the United States, residing at Castella, in the county of Shasta .and State of California, have invented new and useful Improvements in 'Turbine Motors, *of

which the following a specification." This device. relates to that class of mo tors whereby a ,plurality of disks provided with wings or blades, or other form of impact surfacesja i .mused. to rotate by fluid under pressure,1 whether -the same be. constant or intermittent,-.and relates more particularly to the;."fneans whereby the-flow of motive fiuid'is controlled and. directedto 'the power-imparting, inechanism- I whereby motive force may be produced'by the ignition and explosion of-gas under pressure, Whether the same is generated ex terior of the controlling mechanism, or generated within the limits of the same.

1 The thirdiobject is to so combine the inipact receiving mechanism in connection with the fluid pressure controlling or generating mechanism whereby the same will form an operative rotary or t urbine motor from which power may be taken for either sta -f tionary or portable use.

In the accompanying drawings, Figure 1 is a longitudinal section on line of the main shaft. Fig. 2 is a front elevation of one of y the disks. ig. 3 is a plan view of a series of the-same.

Mounted uponthe shaft 2-, andsecured thereto 'by means of a key, orother suitabledevice, is a disk 4: throughwhichzro tary motion is imparted to said shaft, as later described. Secured to the diskf l is a suitable raceway i {a like raceway is'i'pro- I vided on the head 1', and between theserac'e avays are interposed balls, the "same forming 'an antlfriction thrust bearing.

aslater described. Secured to the periphery'ot' the disks 45 ,are Wings 01 blades 9. These blades may be 'arranged at'an'engle to the face-of the disks l'5, or-may be .con-

Operating within 10 the chamber-1O is a pistonhead -or"-valve 12 secured to the .piston-rod 13, extending through the compression chamber 14, the chambers 10 and 14 being so arated by a wallet-partition 15. Secure to the rod 15 13, and adapted to operate within the chamber l4-is a second piston-head 16, the purpose of said head being to compress air, and discharge same through the port 17, into a suitable receptacle. Port 17 serves as a relief and, charging port for chamber 14. The chamber 14 has a closure 01:.head 18 through which the iston-rod 13 reciprocates. The outer end of the rod 13 is provided with a tappet -or collar 19, which is adjustable thereon. The ignition mechanism is operated by means ofa collar 20 secured to the rod 13, and has a longitudinal arm 21. Interposed between the collar 20 and the head 18, is the spring 22. Chamber 10 is provided with a port 23 for the ingress or egress of atmosphere or spent gases. A restricted port 24 communicates .with the at mosphere, the pur ose of the latter being to trap the air an form a cushion for the piston-head 12- in its 'forward or active stroke. v

, B and C are valve housings, one for the admission of airand the other for gas, the combining of which in their proper propor- 49 tions 'forms the explosive charge.- The valves which operate within the said housings, are operated by means of the lever 25 fu crumed u on the standard 26, and operated in one irection by means of the spring 27, and in the other by means of the lever 28, the latter being fulcrumed upon a bracket 29 secured to the head 18, the lever 28 being operated in one direction by the upturned portion 29 in the extension of the collar 20, and in the opposite direction by means of. a spring 30 surrounding the stem 31 of valve 32. Secured to the stem 31 is a. piston 33 operating within the hous: ing C. The housing G is provided with ,two ports 33, one of which communicates with the atmosphere, and the vother with the interior of the chamber 14, behind the piston-head. Gas, air, or other mixture is .in-

troduced into the housing Q through port 50 34, thencearound the valve 32, and through passage 35 into'chamber 10, to the rear side of the piston 12. The valve housing B is arranged at a right angle to the housing C, and contains a valve. 36, with passages 55 through same, adapted to be closed when the valve is seated, and opened when operated by means of the lever 24, to which the valve stem is. connected. hen the said -valve is oil the seat fluid is free to pass iiiderythe same being operated to a stop in one direction by means of the spring 41, and in the other by means of the extension on' collar 20. By this operation any well known 30 make and break device is applicable, one terminal of which is insulated from thecylincler and immovable, while the opposite terminal ma Y have electric connection to the same, and a a'pted to be advanced by means 5 t of the lever 40, by which means the circuit is closed, a spark being produced when the contact points are separated.

The operation of this device is' as follows: Starting with atmospheric pressure in the cylinders and in theair receiver, and with the electric circuit either open or closed, but assume the same to be open, in which case there would be no ignition of either aburning or explosive mixture. Sutficient air 5 pressure in the receiver may be attained by. operating the piston 16 in thecompression cylinder 14 by any means that may be advantageous to produce a reciprocating movement of same, by means ofthe piston rod 13 extending exterior of the eom n'ession cylinder. All parts connected to, and operated by the movementof the piston rod 1? will operate through their predetermined cycle of operation. During the said piston operation, a charge of air under pressure is de-' livered into the chamber 10 behind the piston head 12 through the port .35. Around the valve 32, in the honsin s C. a gas or liquid may be received through the valve 36, and is combined with theatmosphere enter= ing under pressure. During such admission behind the piston '12, the latter will move as indicated by the arrows, F ig. 4, until the collar,19 contacts with the collar 20; and during such movement there will be only frictional resistance. The further movement of the pistons will meet with the resi tance of the spring 22, compressing the same. and relieving the leverQS from contact with the arm on collar 20, permitting the spring on valve-stem 31 to act and close valve 32-, at

the same time the lever 35,- by means of spring 27 will operate valve 36. thus closing all communication between the source of motive fluid supply and the explosion cham her at the rear of the piston 12. The explosion chamber 10 now being charged with explosive mixture, and the piston '12 having moved a su fiicient distance to expose the 139 broken,-and a spark A between the terminals of the i ;n1ter, thus igniting the charge within the explosion.

lever 4.0, thus closing the circuit between the terminals of theigniter. The further travel of the piston 12, due to the expan ion of the fluid under pressure, the lever will he released from contact with its operating means before described, when the circuit will be caused to jump across chamber and generating a fluid under high pressure so as to drivethe piston forward and uncover the passages 1t; whereupon the said fluid will escape through the passages 11, and impact against the wings on thedisks causing the same to revolve. The power thus attained on the first disk 5 is imparted to the nextdisk 5 through the medium of the intermediate pinions 7. The final disk 4-. of the series being secured to'the shaft 2 will rotate the latter with the power imparted through the effective force of each and every disk The fluid medium willthen escape through the discharge opening 5 to the atmosphere.
