To all whom it may concern.'

Be it known that I, ALBERT C. FISCHER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Revoluble Engines, of which the following is a specification.

This invention relates t-o a revoluble wheel tire and has reference to a wheel or engine having a non-revoluble, central annular frame to provide bearings for a revoluble tire, `useful as a band-wheel or for traction or other purposes, one of its objects being to apply a driving power at or near the periphery of the tire.

rI`he invention consists of the novel construction, combination and arrangement 0f parts as described herein and claimed, and as illustrated in the accompanying drawing, wherein,

yFigure 1 is a view of the device in side elevation, parts being broken away andgin section. Fig. 2 is a, sectional view of the same longitudinally of the tire. Fig. 8 is a sectional view through the wheel on line 3 3 of Fig. 2. Fig. 4 is a transverse section on line 4 4 of Fig. 2. Fig. l5 is a transverse sect-ion on lin'e 5 5 of Fig. 2. Figs. 6 and 7 are enlarged, detail views showing a clutch. Fig. 8 is a sectional view on line 8 8 of Fig. 2. Fig. 9 is a Sectional view on line 9 9 of Fig. 2. Fig. 10 is a broken away view of the engine or wheel" in side elevation to illustrate means for readjusting the pistons and for expelling exhaust gases. i

While the invention is illustrated and described in connection with the expansive force of ignited gas as aY source of power, I do not wish to be understood as limiting myself in this respect, nor to size, form,

l proportion or minor details of construction further than determined by the scope of the appended claims.

In the drawing, which illustrates one embodiment of the invention, I have shown a non-rotatable support consisting, in part, of a central bracket l provided with a spindle 2 upon which, by means of keys 3, is secured a hub 4 having radially disposed spokes arranged in pairs, as the pairs '5, 5, and 6, 6 and the pair 7, 7, the outer ends of the s spokes being provided with a rim or annular tire-support 8; the hub, spokes and rim thereby providing a non-revoluble wheelmember or support. Numerals 9 indicate a pair of bearing-blocks which are stationary with respect to the rim and Which project outwardly of the ends Vof the spokes 7 and 7 At 10 is indicated an annular casing or tire, substantially of U-shape in cross-section,its end Walls or sides being adapted to engage numerous balls or rollers 1l which are disposed in suitable grooves formed in the opposedannular recesses 12 of the rim 8, and means are provided to cause a revoluble movement of the tire on said bearings, consisting in part, of the pair of segmental cylinders 13 andv 14, these being secured within and at diametrically opposed parts of the casing, each being provided with a central, longitudinally curved tube 15.

A two-faced ring gear 16 is provided and is disposed substantially at the middle of the tire, within and movable through the tubes 15. It is adapted to have bearings upon balls or rollers 17 which are interposed between the inner part of the ring gear and the bearing-blocks 9. As best shown in Fig. 3, idler gears are employed in pairs and arranged in the tire, as the ` pairs 18 and 19, the gears for each pair being disposed upon opposed sides and engaging the ring gear, and mounted in the blocks 9 for rotation, said gears also engaging the opposed annular racks 20 of the tire.

Numerals 21 and 22 respectively indicate curved pistons and curved piston rods for the cylinders. Each piston rod is of tubular form and circumscribes and is adapted to have slidable movements Ona tube 15. Also each piston rod is provided at its outer end witha clutch, best shown in Figs. 6 and 7, each clut-ch consisting, in part, of a housing 23 secured to a piston rod by a keeper 24.- disposed in a slot 25 formed in the housing. Numeral 26 indicates a paWl foreach clutch, said pawl being provided with a tail-piece having an inclined face or contacting-part a, and it will be understood that when a piston is actuated for moving a piston rod outwardly of a cylinder, the piston rod may have a limited movement within the housing 23 for engaging the inclined part a. of the pawl to thereby move the tooth ot the pawl into engagement with the ring gear., the outward movements, in alternation, ot the piston rods and the pawls, operating to move the ring gear. When a upiston begins its movement inwardly of a cylinder the pawl will be released from the ring gear on account of the form or inclination ot' its inner wall 7), said wall being disposed at an obtuse angle. to the longitudinal axis of the tooth.

Hydrocarbon is conducted to each cylinder in alternation by actuation of the pistons. At 2T (Fig. 9) is indicated a passageway formed in the bracket 1 in communication with any suitable source ot' gas fuel supply and in communication with the passageway :28 formed in the spindle the latter' passageway also being in constant communication with passageuavs 2S) and 229 ot' the` respective spokes 5 and 5. lhen the piston otl the cylinder 13 moves toward the front end ot said cylinder, the gas will enter the rear end thereof. by suction from passageway 29 by passing the tube. 3() and check valve 31 (Figs. 1` 2). At 32 is indicated a conduit communicating with the rear end of cylinder 13 and with the front end ot' the cylinder 14. and it is obvious that a rearward movement of the, piston ot' the cylinder 13 will cause the gas to enter the cylinder 14, said gas not heilig permitted to return, since such return will be prevented by reason of a check 'alve 33.

Hydrocarbon is conducted to the front end ot the cylinder 13 in a manner similar to that just described. 'hen the piston of cylinder 14 moves toward the front Aend thereof, a charge of gas. by operation ot' suction. will enter the rear end of said cylinder from passageway Q9 by passing a tube 34 and check valve 35. A conduit 36 communicates with the rear end of the cylinder 14 and with the front end ot' the cylinder 13, and a rearward movement of the piston of cylinder 14 will cause the gas to enter the cylinder 13, and by means ot' a check valve 37, the gas will be prevented from returning.

Numerals Q8 indicate. spark plugs provided forthe cylinders, and any suitable arrangement may be made for sparking, so that the charges of gas in the cylinders will be ignited in alternation and at the time the gas is compressed therein, at each complete rotation of the tire. Means are shown and will be described for Acausing ignition of gas in the cylinder 13. this being considered sufficient since the construction Iand arrangement of parts for this purpose is the same for both cylinders. At 38 (Fig. 1) is indicated a conductor electrically energized by any suitable means. and adapted to electrically energize a horizontally projecting brush 39 which is suitably'insulated and mounted on a yoke 40 carried by a block 9. Numeral 41 indicates a second brush which is also insulated and mounted on said yoke, this last named brush being` in communication with an adjacent spark plug by means J n electrical conductor c as plainly shown in Fig. 1. By this construction the electrical circuit is incomplete between the brushes` 39 and 41. By referring to Fig. 3. It will be seen that the inner side of rthe tire is provided with a pair of insulated contact-blocks 42 electrically in communication by means of a conductor 43. and it will be understood that. during a complete rotation ot the tire. the blocks 42 carried thereby will make contact with the brushes` 3f) and 41. this contact completing the electrical circuit to cause a sparking for igniting the gas within the cylinder 13.

By the construction as described the tire is provided with .a single pair of contactblocks, and during a complete rotation of the tire said pair of blocks are engaged by the brushes disposed near and at the front. of both of the cylinders. whereby sparking for the cylinders is accomplished, the piston rods moving outwardly of the cylinders in alternation, the clutches gripping and moving the ring gear, the movement of said ring gear in one direction causing the tire -to rotate in an opposite direction on account of the pairs of beveled gears 18 and 19. the momentum of the tire heilig depended upon for causing a part of its rotatable movement while not engaged by a clutch, if only two cylinders are employed, as shown.

In order that the pistons may be completely reciprocated to expel exhaust gases and 'or compressing the charges of gas. devices are provided consisting, in part, ot' a pair of pinions 44 best shown in Fig. 4, having rotatable bearings in the rim 8. Numeral 45 indicates an actuating arm or curved rack-bar disposed between and engaged by the pinions 44, said arm being mounted upon the piston rod of the cylinder 13. Y

Numerals 46 indicate a pair of actuating arms or curved rack-bars (Fig. 4) each being engaged by a pinion 44, said arms 46 being connected With a yoke (Z which is mounted on the piston rod of the cylinder 14. and by this construction it will be understood that when the piston rod of cylinder 13 moves outwardly, the arm 45 will move in the same direction, and it will cause the pair of actuating arms 46 to move, simultaneously therewith, ina reverse direction to the movement of said arm 45, to thereby move the piston of cylinder 14 inwardly, this inward movement causing the new charge. of hydrocarbon which has entered said cylinder 14, to be compressed, the spent. gases having been previously expelled by the entrance of said new charge as is usual with two-cycle engines.

As thus described it will be understood that when the piston rodof the cylinder 14 moves outwardly, the pair of arms 46 will move in the same direction. and will cause the arm 45 to move in a reverse direction asoma? to the movement of said arms 46 for moving the piston of the cylinder 13 inwardly, said inward movement causing the exhaust gases to be expelled from the cylinder 13, and causing the fuel gas which enters therein to be compressed. I

By referring to Figs. 2, 8 and 9, it will be seen that the exhaust gases may move outwardly from the cylinder 13 by entering the narrow pockets cl formed in the bottom of said cylinder, and from thence moving through the passageway 47 of the spoke 6, and after entering the passageway 48 of the spindle, may move out of the passageway 49 of the bracket-support 1, the exhaust gases from the cylinder 14 moving outwardly by passing similar passageways e', 47. 48 and 49.

Having fully described the several parts and their uses, a further explanation relat ing to operation is not necessary.
