be insured with absolute certainty and safety, Referring to the drawings for a further description of the invention, A represents the rolling rim or tire,made,preferably, T-shaped in section, of any Suitable material, the surface of which is grooved out to receive the ring B, of rubber or other suitable material. Formed integral with or otherwise secured to the tire A are four struts, a, arranged opposite each other, and their angles being at about forty-five degrees and one hundred and thirtyfive degrees, respectively, from the center of the wheel. These struts are secured onto the web of the tire A and project outward from both sides of the tire and upwardly for supporting concentrically the respective hubs O, in a manner to be hereinafter fully described. The struts a of the tire A are braced by means of metallic wires or rods a, so as to insure greater rigidity to these struts. The rod a, for example, is suitably fastened at one end to the web of the tire A at a and thence passes through an eye, of, in one end of the first strut a, thence passes through another eye, a, in the second strut a on the same side, thence through an eye, a, formed in the web of the tire A, and thence through the eyes in the opposite ends of the two struts a, the free end of which rod is then secured to the former end of the rod a by forming a knot, or the two ends of the rod a may be provided with right and left threads and a swivel-nut attached thereto for holding the two ends firmly together. The tie-rods a are suitably fastened in apertures provided in the web of the tire A and pass through central openings in the respective struts, and which tie-rods are employed to equalize the power or weight upon the whole structure -that is to say, to prevent the tire from its light nature from becoming trans formed from its circular form into undesirable shapes.

At suitable distances apart in the surface of each shell 0 of the hub O are inserted four eyes, 0, which are held to place by means of nuts 0 fitted to the threaded stems of these eyes from the interior thereof. These shells and hubs are supported centrally in position by means of the metallic tie-rods c and 0 which passthrough the respective eyes 0 of the shells. The tie-rods 0, having their respective end extremities threaded, are inserted through the ends of the struts a and held thereto by means of nuts 0 and the respective hubs are thereby readily adjusted or tightened. On the respective stays or tierods 0, between the eyes of the shell and the struts, are rigidly secured collars c for the reception of the extremities of the tie-rods 0 Each tie-rod 0 passes through an eye 0 in the shell 0" of the hub C, and is provided with threaded extremitiesinserted through said collars c and to which extremities nuts 0 are attached for holding each hub in proper position.

It will be seen from the drawings that easy access to the seats can be had from either side of the vehicle, and, furthermore, that all side friction between the hub and axle is overcome, which has been one of the main objectionable features to many of the heretofore existing monocycles with spokes, and, moreover, when spokes are used the vehicle has to be constructed very largein diameter in order to secure the requisite amount of space for the seat and pedals, while by my arrangement the ped-' als or footrests are only a short distance above the ground,and hence, as the seats are located beneath the axle, the center of gravity will therefore fall beneath the axle,and the balance, as well as the operation,of this monocycle will be much easier accomplished than by any of those heretofore constructed.

The hubs O are loosely mounted onto sleeves 0, Fig. 5, around which they revolve by mechanism to be hereinafter described. To these sleeves G a frame, 0 in the form of a stirrup,is fastened, supporting the seats Dand D, adjustably mounted on the horizontal T- shaped bar d, supported by the vertical post dand brackets or struts d suit-ably bolted to said T-shaped bar.

The mechanism for operating my improved monocycle will now be described.

Each hub O has a ratchet, 6, cast therewith, or this ratchet may be secured thereto in any other suitable manner, and on each side of this ratchet e is a smoothsurfaced rim, e, on which the pawl-lever collar 6 operates, and which collar is preferably made in two parts, 6 and c suitably secured togetherfor instance, as shown in Fig. 4. The pawl 6 held in the upper section, a by the pin a, is kept in contact with the ratchet e by the spring 6''. Integral with the upper section, 6 of the collar e is formed a lever-arm, 6 for operating the pawl e The double pedals E and E, journaled to the shaft F, are connected to the lever e of the pawl-lever collar 6 by the connecting-rods f and f, and are operated by either one or two persons sitting on the seats D and D. The lever G is located beneath the pedals Eand E, with its ends fitting into eyesg and g fastened to the underside of the pedals Eand E,.and this lever is pivoted at its center to the vertical post 01, rising from the frame 0 This lever G serves to throw one pedal,E or E, with its connecting-rodf orf and lever a respectively, upward while the other is moved downward by the foot of the operator, and vice versa, in order to accomplish a steady movement of the monocycle.

If the monocycle is operated by two persons, the seats D and D will be in the position shown in Figs. 1 and 3 of the drawings, with their re spective feet on each roller h and It, journaled in the endsv of the pedals E and E; but if only one person is riding therein the seat D will be brought to the center of the T-bar d,'so as to have the center of gravity beneath the center of the monocyle, and the feet of the operator will act on the rollers h, having the heels thereof in the openings h of the pedals E and E. The seats D and D are fastened onto slides d and d, encircling partially the horizontal T-shaped bar 01, and are held thereto by means of set-screws d These seats may be made of any convenient shape, having springs between them and the slides d and 01*, so as to overcome whatever jarring may be produced in riding over uneven roadways, and these seats are by preference provided with backs d", to afford more comfort to the persons riding and a feeling of greater security.

To steer, brake, and guide my improved monocyele, the springs I and rollers I are employed on each side and are operated by the following mechanism: A shaft, J, revolving in each of the sleeves C, has at one end a bandle, j, and at the other end, at a right angle to this handle 3', an arm, h, Figs. 1, 2, and 5. To this arm h a bar, h, is hinged or pivoted at it, having a recessed arch, 71., provided with a series of pins, h, fitting into a hole, if, provided in the disk 0 This disk 0 is feathered to the sleeve 0', and is revolved around the same by its arm k having a hole, h into which a pin, it, fastened to the arm h, slides. To guide the arch or quadrant k and hold it more rigidly, a recessed stud, h", is also fastened to the arm h, as shown in Fig. 5. One of the pins If of the arch is always kept in the hole h of the disk 0 by the action of the spring j, fastened to the handlej and bearing against a grooved hub, 0 of the frame (3; but if it should become necessary to change the position of the spring I and roller 1 the pin h may be brought out of contact with the disk 0 by the handles 9' and j. The handle j is pivoted to the handlej, which is secured to the outer extremity of the shaft J, and the handle j has a curved upper extremity which engages with a groove formed in the hub 0 By pressing both handles] andj the spring j is compressed and the shaft J moves outward, and with it the arm h", arch h stud h, and pins h and h. The pin h is now released from the disk 0, while the pin it is still engaged with the arm he of the disk and by turning the handlesj and j now to the left, as shown in Fig. 1, the bar It, and with it the spring I and roller I,will rise, the disk 0 will be turned by the pin it, presenting the pin h to the hole h of the disk 0 and by decreasing the pressure of the handlesj andj the spring will be brought into action and the pin h will engage with the hole If of the disk 0, thereby suspending and holding the spring I and roller 1 at any desired height above the ground.

To steer my improved monocyele around a corner or to describe a curve with it, both devices J and J provided with handlesjand j are grasped by the operator and compressed to release the pins h on the disks and by turning both devices J and J in opposite directions-that is to say, bringing the spring I To stop the monocyele, both devices J and J should be turned in one direction, causing the springs I and rollers I on both sides to slide sufficiently on the ground to promptly retard its motion, and finally stop the monocycle, if from any cause it ceases to come to a dead-stop through failure to operate the pedals actuating the ratchet mechanism. If the operator has a good road, he may elevate the rollers I and springs I out of contact with the ground, as shown in dotted linesin Fig. l, and the spring j of the handles will serve to hold the pins h of the arch in the hole k of the disk 0, thereby keeping the bars h, on which the springs I and rollers I are fitted, in position without the aid or assistance of the operator.
