ROTARY MOTOR.

SPECIFICATION forming part of Letters Patent No. 645,650, dated March 20, 1900.

Application filed September 30, 1899. Serial No- 732,2Z4. (No model.)

To all whom it may concern:

Be it known that I, J AMES BEARD SAMPLE, a citizen of the United States, residing at O- lumbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in Rotary Motors; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to IO which it appertains to make and use the same.

This invention relates to an improvement in motors, and more particularly to that class wherein revolving pistons are employed for driving the transmitting-shaft and itconsists [5 in the construction and arrangement of parts as hereinafter described, and defined in the claims.

The object of my invention is to provide a motor wherein the'employment of the mechanical principle of an inclined plane may be successfully used in conj uncture with the outwardly-propelled pistons moving on the inclination of the plane, the contacting surfaces being such as to rapidly carry the motor 2 5 forward or propel it.

Many attempts have been made heretofore to provide a satisfactory machine of this character which would effectively meet the requirements of the particular use and commero cial utility; but as far as I am aware the efforts in this line have been more or less unsuccessful, owing largely, in the first instance, to an unusual and objectionable friction between the Various parts, and, further, in the 3 5 complication of mechanisms involving valvegearin gs and adjustable features which, while rendering the devices interesting, destroyed their practical utility. My invention is designed to provide an engine of the particular 40 type above indicated which will involve simplicity in structure, ease in operation, and a relatively-small amount of friction.

With this end in View a constructive embodiment of the invention is shown in the accompanying drawings, wherein- Figure l is an end elevation showing the shaft in section. Fig. 2 is alongitudinal vertical section through one of the motors, it being understood that in the completed machine four motors of the same type will be used, the

same being duplicates of the first.

In the drawings, A represents the base of the engine, which is of any convenient or ap proved form, and B B are vertical standards containing the journal-boxes b, in which the shaft B is journaled, the shaft carrying any suitable transmitting structure, such as a pulley B Mounted on the shaft and conveniently keyedor fixedly secured thereto is a cylinder disk or wheel 0, having four cyl- 6o inder-cavities c, 0, c and c therein, extending radially and arranged equal distances apartthat is, the adjacent cylinders being at an angle of forty-five degrees to each other. These cylinders have at their lower ends on 6 5 opposite sides admission-ports and exhaust ports 1 and 2, respectively. The cylinderbase is formed with a slight projection to retain the piston D in a position to be quickly acted upon by the incoming motive fluid. 7c The pistons D are so fashioned as to work in the cylinders and are held therein against complete outward movement by a flange 0r collar d, located at the outer end of the cylinders, which abut against the shoulder portion of the pistons. The ends of the pistons extend beyond the cylinders and have secured thereon suitable brackets D, in which are mounted antifriction rolls or wheels D the same being carried by suitable shafts mounted in the brackets.

Mounted on the base A and surrounding the cylinders, but spaced therefrom, are the rings or tracks E, each being rigidly constructed and firmly bolted or secured in any convenient manner to the base. These rings are provided with the gradually-inclining wa s or tracks E which extend some considerable distance and terminate at the point e, from which point a very abrupt inclined o plane or Way E is formed, terminating at the face of the wheel. These ways are of rigid formation and are permanently secured to the ring. There are two ways or tracks E and E located diametrically opposite each other, 9 5' as shown in Fig. 1, and their distance toward the center is such that as an antifriction Wheel of a piston comes in contact with the gradual inclination of the way E it will ride up thereon and by that means he forced back into the cylinder.

To form a convenient, economic, and durable valve or portage system to the engine, I place on opposite sides of the wheels or disks 0 the steam-chest F and exhaust-chest G. The former is conveniently secured loosely on the shaft and is held in its proper position by an adjustable flexible arm F, secured adjustably to the base by a suitable bolt or screw f engaging the projection f on the base, and also by the induction-pipe F The steamchest is shown fashioned so as to fit snugly the side of the disk and is provided with the inlet-ports 10, with which the inlet-ports 1 of the cylinders register during the movement of the disk. In this type of construction it is necessary to have a close joint formed between the steam-chest and disk to prevent the escape of steam or other fluid through the space between the chest and disk. To accomplish this, I mount on the shaft a block 13, the same having its outer face resting against the end of the journal-box of the standard B. This box carries a series of longitudinally-extending hollow nipples 13, which project through the stufiing-boxes 15, carried bythe steam-chest, and through apertures formed in the side walls of the steam-chest. This construction enables the steam-chest to slightly vibrate longitudinally on the shaft,the springstandard and pipe holding it in its normal position slightly out of contact with the disk.

When the steam is forced into the steamchest, it will find a permanent backing against blocks 13, and owing to the steam-chest having slight movement the pressure of the steam against the fixed surfaces will have a tendency to move the chest toward 'the disk. This, however, is not accomplished until the steam issuing from the ports 10 will snfficiently lubricate the sides of the disk to prevent any undne friction therebetween. The pressure of the steam exerted against the steam-chest will, however, very quickly close the space between the same and the disk sufficiently tight to prevent the escape of steam.

The exhaust-chest is largely a duplicate of the steam-chest, except that the chest is provided with an' exhaust-pipe 11 at its base for the carrying off of the exhaust and water of condensation. This exhaust-chest is also provided with exhaust-ports 22. To hold the ex haust-chest in proper relation to thedisk, a steam-chest 12 is' formed at the side thereof, into which the small steam-pipe 12 enters. This chest is also provided with stuffing-boxes, through which the nipples 14 project into the chest, the nipples being carried by the block let, mounted on the shaft and held in position by the journal-boxes of the standard 13 or in other convenient manner. To permit the water of condensation to escape from the steamchest 12, a suitable petcoek is provided.

In operation the pistons are arranged, as shown in Fig. 1, with the ant-ifriction-rolls resting on the point between two inclined planes. The steam is then admitted to the steam-chest and, issuing through the ports with great force, forces the pistons outward,

carrying the rolls onto the inclined propellingplane, and thereby advancing the cylinders.

very rapidly, and the momentum given the cylinders and their pistons is such as to cause the same to move rapidly around; but owing to the duplication of the engines the power is being constantly applied every sixteenth of a revolution, the engine being set to accomplish this result. The momentum and assisting force of the first engine carries the antifriction-wheels into engagement with the inclined way E which gradually and without sudden shock forces the piston back into the cylinder ready for repeated action. It will be noticed that in this machine during the greater part of the movement of the piston the anti friction-wheel is wholly out of contact with the ring, thus largely reducing the friction during that interval. I

I have shown in the drawings a structure whichis susceptible of various modifications, and I desire it understood that many changes and alterations can be made without departing from the nature and principle of the invention.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, :is-
