To all whom it may concern: I p d Be it known that I, JAMEs WHALEY, a citizen of the United States, and resident of the city of Pawtucket, in thecounty of Providence and State of Rhode Island, have invented certain new and usefullmprovements in Internal-Combustion Enginesof which thefollowing is a specification.

This invention relates to nternal combusiJIOII BHgIHGS ofthe rotary type, and the ob- 'ject of the invention is to provide in such an engine, arotor which includes cylinders provided with a plurality of;r.ec1procating pistons, said pistons .beingall connected to act upon the individual arms of ,a-connnon mem her or spider, the axisof rotation ofsaid member being set on an angle to that of said rotor, whereby the action of thedifl'erent pistons upon the arms of this member produces a revolvingmotion or torque to the rotor- 1 k 7 v a A further object of theinvention is to provide a IOILOII the end of-each armwh ich engages the piston, thereby reducing to the minimum the frictional movement of the arm upon the piston head. 7 r l A further object of the invention is the provision of a laterallyextending roll member connected to the body portion of the spider, to prevent a relative rotation of the spider and rotor.

rotation of the piston in its cylinder.

A still further object of the invention is the provision of means in the guide block Y on the piston whereby it may be adjustedto talge up the wear and lostmotion of theroll on the spider arm. t I

lVith these and other, objectsin view, the invention consists of certain novel features of construction, as will :befmore fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of theengine partly sectioned on line 1-1 of Fig. 2.

Fig. 2is a section on line 22 of Fig. 1 looking in the direction of the arrow.

Fig. 3 is a detail view of the spider member.

Fig. l is a view showing a portion of one of the cylinders with the piston mounted therein thereto, p l H t r Fig, 5 is a -perspective View ofthe guide plate. I 1

Fig. 6 is an elevationpartly in section on one of the pistons showing the shims under the guide plate whereby said plate may be adjusted to take up the wear orlost motion of the spider roll. t 7

Referring to the drawings, 10 designates the bed plate oft-the machine which is provided with standards 11 and 12,011 which the -motor is supported. i I

' The member termed the rotor is prefen ably a circular or drum-shaped. casting l having: a guide plate connected VI bored to provide aplurality of cylinders cylindersare connected by a central sleeve 16 to; the main shaft 17 by a key 18, or other attaching means, and -.tl1e, cylinders are su pplied with ggas from the 'carbureter ,2;7 through the hollow. portion 19,015 ,the {shaft 17, which shaft is provided with ports .20 communicating withthe passageways -21 to admit the gas tothe cylinders through the valve 22, the, valve 23 controlling the exhaustgases which pass out through the passageway 24 and so totheopen, through discharge pipes (not shown).

Each 'ofthese cylinders isborded to receive'a piston 25 which is provided with a recess or pocket 26 on its outer end to receive an arm of the spiderQS. I f

This spider. has a body :portion 29 preferablymade in the form ofa ring, see Fig. 3, and has radiating arms-36 adaptedto project into the different cylinders and into the pocket of each of the pistons, the end, of each arm being provided with ananti-triction roll 37 .which worksv between the two hardened steel plates '30 and 31 on thepiston. Theiinnerplate 30 has a boss32-eX- of shims or washersfiaare located beneath this plate 31 whereby itvmay =be adjusted so as to take up any wear or lost motion of the .roll 37 and. so insure a quietfin nningengiine.

wardly projecting lip 35 which extends into ,This plate is also provided with a forthe opening 15 in the cylinder so as. to prevent rotation of the piston therein. This spider is also provided with a roller 38 extending laterally from its body portion 29 into a groove 39 in the cylinders, to hold the arms in alinement with the cylinders.

The ring shaped body portion of this spider is preferably mounted on ball bearings l0 on the hub member 41, the axis of which hub member is set on an angle to the axis of theshaft. This hub member is held against rotation by bolts 42 through the bearing 11, by which construction the pressure on the pistons against the arms of the spider causes the rotor to revolve and providethe necessary torque on the shaft, the power from which may be transmitted through the pulley 4:3 or through suitable means. 7 By arranging the axis of rotation of this spider member on an angle to that of the rotor, itwill be seen that this spider acts as a cam by which the pressure on the pistons causes the rotor to revolve, and the greater the incline ofits axis relative to that of the shaft, the greater is the stroke of the pistons and'consequently the easier the cam action.

' I have illustrated one means whereby my invention may be carried out, but I do not wish to llmit myself to this speclfic construetion as various changes of the several features may be necessary. I, therefore, desire it to be understood that I reserve the privilege of resorting to all the mechanical changesto which the device is susceptible, the invention being defined by the appended claims.

I claim 1. In an internal combustion *engine, a rotor, a plurality of reciprocating pistons in said rotor, a member rotatable with said rotor-having arms connected to all of said pistons, the axis of rotation of said member being set on an angle to that of said rotor.

2. In an internal combustion engine, rotor, aplurality of reciprocating pistons in said rotor, a rotatable member having arms, each being provided with an end contacting with one of said pistons, and means whereby said member is caused to rotate on an axis setat an angle to the axial rotation of said rotor.

8. In an internal combustion engine, ,a rotor, a plurality of'reciprocating pistons in said rotor, a rotatable spider having arms each provided with an anti friction roll engaging each 'of said pistons,-a fixed hub on which said spider is rotatably mounted, the axis of said hub about which said spider revolves being set on an angle to the axial rotation of said rotor.

Copies of this patent may be obtained. for

0mm plurality of-reciprocating pistons in said rotor,--a'rotatable spider having arms "each provided with an anti friction roll engaging the center portion of each of said pistons, afixed hub on which said spider is rotatably mounted, the axis of said hub being set on an angle'to the axialrotation of saidrotor, and a guideroll projecting fromthe bodyof said spider into a recess in the rotor to prevent relative rotation of thespider androtor.

"6.,In an internal combustion engine, a rotor, aplurality of reclprocatmg pistons in said rotor, each piston belng provided with a pocket open through its side wall, a member rotatable with said rotor having arms each extending into the said pocket in each of said pistons to work between the inner and outer walls thereof, one of said walls being adjustable to take up lost motion of the arm end therein, and means whereby said member is caused to rotate on an axis set at an angle to the axial rotation of said rotor.

7. In an lnternal combustion engine, a

rotor, a plurality of reciprocating pistons in 'sald rotor, a rotatable member having arms connected-into eachof said pistons the axis of rotation of said member being set on an angle to that of said rotor, and means for guiding said piston to prevent rotation in itscylinder. I

8..In an lnternal combustion engine, a

rotor, a plurality of reciprocating pistons in i said 1Ot01, each piston being provided with a pocket, a rotatable member having arms each extending 1nto the sand pocket in each of said pistons to work between the inner and outer walls thereof, one of said walls being adjustable to take up lost motion of the engaging end, means whereby said member iscaused torotate'on an axis set at an angle to the axial rotation of said rotor, and

means for guiding said piston to prevent rotation in its cylinder.

In testimony whereof I aflix my signature in presence of a witness.
