MOTOR.

Application filed V1:"ebruary rlhis invention relates to new and useful improvements in motors, and has'particular relation to motors of the, radial internal combustion type.

One object of the invention is to produce a radial, internal combustion motor, spew cially adapted for use in aircraft.

Another object of the invention is to produce a motor of the character' described embodying a novel combination with the motor proper of means for securely fastening the "motor onto the frame of the fuselage, said iastening means embodying also a manifold provided with an intake conduit from the carbureter and distributing intake pipes through which the motor fluid is delivered to the cylinders. l Y

A still further feature of the invention resides in the provision of suitable counterweights carried by the propeller shaft, and which together with the wrist pin bearing form in effect a balancing wheel or momentum wheel.

The type of motor herein described may be f obsolet'e rotary motors, and said rotary motors thus converted into motors of the-radial type.

Vith the above and other objects in view this invention has particular relation to certain novel features of construction, operaf tion and arrangement of parts an example of'which is given in this specification and illustrated in the accompanying drawings, wherein:- y K' l Figure 1 shows aI front elevation of the motor, partly in section.

Figure 2 shows a side view partly in section. f

`igure 3 shows a sectional view of a `cylinder, taken on the line 3-3 of Figure 2. f

Figure 4 shows a fragmentary planY view ofthe motor, and 1 Figure shows a transverse sectional view taken ou the line 5--5 of Figure 4, and Figure 6 shows a fragn'ienlary edge view of the valve actuating disc.

Referring now ymore particularly to'the drawings, wherein, like numerals of reference'designate similar parts in each of the figures, the numeral 1 designates the motor case as a whole. This case is o f a general cylindrical contour and its forward end is reduced forming a bearing housing 2 for the propeller shaft 3. The foward end ofthis shaft has the propeller 4 fixed thereon.

A plurality of radiaicylinders 5 are pro- 10, 1925. Serial No. 8,3()4.

vided, each provided with spaced annular` heat radiating flanges 6, and each having its inner end threaded through the wall of the case 1. The outer end of each cylinder is closed, and also provided with a transverse web, or partition 7, spaced from said outer end, forming the intake and exhaust cham-` bers Sand 9 separated by a suitable part-ition Vas shown. l

Each partition 7 has the inlet and exhaust ports 8 and 9 controlled by the inwardly opening inlet and exhaust valves 10 and l1. These valves are fastened to stems which work through suitable bearings in the cylinder ends and they are normally held closed by pressure springs 12 and 13. The valves are opened through the yoke 14 which is pivoted on the standard 15 and whose ends are adapted to work alternatively against the outer ends of the stems to open the valves in proper sequence.

ln the cylinders 5 the pistons 16 reciprocate and the connecting rods 17 arehinged, at their outer ends, to the respective pistons.

The propeller shaft 3 has an offset, or eccentric, wrist pin 18, inthe motor case, which is tapering and formed with an annular shoulder 19, at its large end. A sectional bearing 20 is rotatably mounted on this wrist pin and is confined thereon by the shoulder 19, on one side, and the bushing 2l, on the other, said bushing, in turn, being secured on the pin by the nut 22. The bearing 20 is formed of two annular, coinciding sections, as shown in Figure 2, whose margins are spaced apart and formed with annular, opposing, inner, intermediate andvouter channels, 23, 23, 24, 24, and 25, 25. The inner ends of the connecting rods 17 are formed with wide, arcuate Vbearing plates 26, which are disposed to work insaid respective opposing channels to form operative connections with the bearing 20. 1

Qpposite the wrist pin 18 are the segmental weights, or balances. 2 7, 27', spaced apart rods, one of said weights being integral with the shaft 3 and the other being'integral with the bushing 21. These weights, with the wrist pin and its bearing, form in effect a balance, or momentum wheel.

The case 1 is closed by the end plate 28 which is clamped thereto as hereinafter described, Vand fastened to the inside of said plate there is a fixed spur gear 29 which has a bearing. concentric with the shaft 3, pron and on opposite sides of the connecting vided toV receivey the stub shaft i)` which is. formed integrally with the Weight 27. The stub shaft 30 is formed into an eccentric portion 31, between the Weight 27 and the gear 30 and mounted on this eccentric poi.- tion there is a valve actuating disc 82 which has double flanges with` sinusoidal margins. forming, staggered cams, and carries an annular internal rack 33 of larger. diameter than. the gear 29 and which. adapted to run in mesh with the said gear. The rotation of the eccentric 3l, acting. in combination with. the gear 2S). and rack 331, causes. the disc to swing' around theV gear 2S)A but to. i'eniain in, operative connection therewith., thus. providing, in eifefft an eccentric gearing. 'Ehe yoke4 14, of each cylinder, is connected to, and adapted to. be` actuatedv by, a push. rodi, as 34, and these push rods are actuated toy oper f ate the intake and exhaust valves, l0 and ll of the cylinders in the proper sequenceA as the disc 32 swings around its cycle. by the marginali cams of the. marginal Hannes of said disc. This valve. actuating mechanism is conventional and a more specific. illustration aud description thereof is not deemed necessary,

An actuating: shaft 35 has a separahle. con.- nection with the stub shaft, Si()4 and in axial. alignmentthereivith. and works through a centrall bearing` in.. theV end plate 2S. 'lghere is an annular web 36 Whose margin is` bolted to the adjacent end of the4 motor case and clamps the endl plate 28 in. position. This web is formed with an` extended bearing'. 31T in which the shaft 35 runs. Fitted over the. bearing- 37' there is a sleeve 3S, whose end. adjacentthe case. l', is formed with an. annular concave-.convex plate 39 haring' the marginal flange Il()y which. fits Closety around the margin of-i the Web 36. Ain enclosed chamber lll, forming an intake. maanifold is thus formed. TheA inner end oli the sleeve 3S abuis against anoutsidc annular sluuildcr ll2 on the bearing' 37' audits outer end has an enlarged socket 43' and an, inside a anulan: shoulder 44. A bushing/l5 is threaded ov the. outer end of the bearing 37 and abuts against the shoulder. 44.. A retainiiig'- cap stGzis threaded over the outer endof tliebnsh.- ing 45 and retains the anti-friction bearings 4G'. for the shaft in place.

Cast integrally with. the sleeve there is an intake; conduit 4B which lens trom. i@ carburetei.' and enters the manifold ll dnd leading.;l from said manifold there are. the intake. 'pipes 49: whichI radiate. to4 the.. respective, cylinders and. enter the intake cliambersiI 8 thereof. After explosion of the charges they spent ,efases are exhausted through the exhaust ports 50, 501 in the outer ends of the, cylinders.

The outer end of; the sleeve 88 has an an,-
