Application filed March 1,
To all whom it may concern Be it known that I, ALFRED LEE, a citizen of the United States. residing at Bellingham, in the county of \Vhatcom and State of Vashington, have invented a new and useful Explosion-Engine, of which the following is a specification.
The present invention relates to improvements in explosion engines, and of that type, in which an annular series of longitudinal cylinders are connected for simultaneous rotation to serve as a fly wheel and thus dispense with the ordinary balance or fly wheel and make a compact and simple engine particularly for use upon automobiles, air craft and the like, one object of the invention, being the provision of a novel construction and arrangement of parts, by means of which the carbureted air is properly supplied to the cylinders in proper time and exhausted therefrom also in proper time.
A further object of the present invention, is the provision of a rotating member, including an annular series of parallel power cylinders each having a reciprocatory piston mounted therein, the rod of which is guided in a straight line movement by the means that connect the various rotary parts together, said rods also being operatively connected to a cam member whereby the reciprocatory movement imparted to the piston is in turn transformed into a rotary movement of the rotating member which as before stated includes the power cylinders and their pistons, such cylinders constituting the balance member or momentum device and consequently dispensing with the usual fly wheels.
A' still further object of the invention, is the provision of an engine of this character, which is simple, inexpensive and durable in construction and which is thoroughly efli-- cient and practical in use.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of. construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of theinvention.

tion taken on line 2-2 of Fig. 1. Fig. 3 is a section taken on line 33 of Fig. 1, with the portion to the rear of the section dispensed with. Fig. 4 is a reverse view of the parts shown in Fig. 3. Fig. 5 is a section taken on line 55 of Fig. 1. Fig. 6 is a section taken on line 6-6 of Fig. 1. Fig. 7 is a dlagrammatical view of the stationary cam groove.
Referring to the drawings, the numerals 1 and 2 designate the pillar supports or standards of the present engine, the support 1 being provided with the V-shaped member which in turn properly incases the end thrust bearing 4 and has mounted rigidly Disposed for gine later to be described.
The disk 11, which constitutes a common head for the cylinders 12 is connected together with the cylinders by means of the tie bolts 13 to the casing 8, so that the casing 8, cylinders 13 and head 11 rotate in unison. The disk 11 is provided with a port 16 for each cylinder 12 and with a spark plug 17 one for each cylinder, said port 16 constituting an intake and an exhaust port as will presently appear. The ends of the respective tie bolts 13 are threaded to receive the respective lock nuts 13' and 13", so that the head 11 is clamped firmly upon one end of the cylinder 12, while the casing 8 is clamped upon the opposite end thereof. Carried by the head 11 is the inwardly projecting bearing carrying sleeve 14, which is provided with the roller bearings 15 which surround the stationary tubular shaft 5 at such point and thus form with the roller bearings 7 and 31 the proper anti-frictional support for the rotating member of the present engine. The thrust bearing 4 is so disposed as to abut the outer face of the head 11, and thus take care of the end thrust of the rotating parts.
Upon the outer face of the disk 11 are provided the tangentially disposed plates 18, which constitute a fan means whereby when the member is rotating, the air is caused to flow toward the center of the head of the present engine and consequently keep the insure a straight line movement thereof during the reciprocation of the piston 19. Also connected to the piston rod at the junction of the cross arms thereto, is the threaded member 23, which is held in place by the nut 24, and is provided with the truncated member 25, which is anti-frictionally connected to the cone roller 26, which is adapted to fit within the groove 27 between the flanges 27 thereof, of the stationary member 28. Thus as the pistons 19 are reciprocated, the cam groove being stationary, willimpart a rotary movement to the parts 8, 11 and 12 and consequently through the key 8" drive the shaft 6. The member 28 is connected by means of the screw or other means 29 to one-end of the stationary sleeve 5, thus insuring therigidity of such member. Disposed within the encircling ends 30 of the member 28 and about the shaft 6, are the 'rollers '31, thus producing a bearing at this point.
Upon the outer face of the member 11 carried by the sleeve 3 of the standard 1, is a disk 32, which is provided with the intake port 33 and the arcuate exhaust port 34, there being connected to such plate to control the admission of the ,carbureted charge to the port 33, the intake' manifold 35 and also connected to the member 32 so as'to control the exhaust of the burnt gases from the port 34 is the exhaust manifold 36. Thus these parts remain stationary and as therespective ports 16 of the cylinders 12 are brought into registration therewith, the charge is drawn within the chamber of the respective cylinders '12, compressed therein and exploded, as will presently appear to thus impart the desired reciprocation of the piston 19 and consequently through the rollers 25 and the member 28 the desired rotation with the shaft '6.
Toprovide a means for timing the action ogf he ignition system, an arcuate supportiii'g imember 40 which is provided with the elongated slots 41, is attached to the mem-' ber 3 by means of the set screws 42, so that the 'same may be adjusted circumferentially thereon to thus place the'arm .42 which car ries the split clamping member 44 and consequently holds the sparking terminal or- .conducting member 46 place, so that the terminal carried thereby will be disposed in the path of to engage the outer end of the respective spark plugs 17 during the rotation of the disk 11. Thus by moving the arcuate member 40 to different positions upon'the member 3, the energization of the respective spark plugs will be advanced or retarded.
In order to adjust the thrust bearing 4, the outer end of the stationary shaft is threaded as at 48 for the reception of the adjusting nut 49, whose flange is disposed in the path of to engage the sliding rods 50 mounted in the slot 51 of the member 3 so as to project their ends against the thrust bearings 4 and adjust the same relatively to the member 11. This is provided so that any wear may be taken care of at this point.
In order to provide a means for lubricating the present engine, and more particularly the faces of the stationary member 32 and disk 11, the lubricant is supplied through the conduit 37, which opens into the chamber 38 of the member 32, and consequently is fed through the ports 39 between the faces of the respective members 32 and 11 and also through the duct 39to the shaft 6. Other points of lubrication are provided for wherever it is found necessary.
From the foregoing description, it is evident that a recipro-rotating four cycle valveless explosion engine is provided, the members 32 and 11 constituting the valve for the intake and exhaust of the gases and thus rendering it unnecessary for the use of other valve mechanisms as is the usual practice in engines of. this character. The extreme inner end of the exhaust port 24 is about 5 degrees from the extreme inner end of the intake port, so that shortly after the exhaust, the port 16 of the respective cylinder is brought into registration with the intake port and thus as the piston 19 is moving inwardly, the charge is drawn in, this requiring an 85 degree revolution on the part of the member 11 of the cylinder 12 before the piston begins to return to com press the explosive mixture during a period of approximately 95 degrees of a revolution when the explosion occurs, the port 16 being closed during the explosive stroke for approximately a period of 75 degrees of the Thus with-each revolution of the I ing members, one for the tubular shaft and a the other for the free end of the rotatory shaft, a plurality of cylinders disposed ra.-,
