Letters Patent No. 114,135, dated April 25,1871; antedated April 18, 1871.

IMPROVEMENT IN WHEEL-SKATES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Beit known that I, GEORGE YV. HAWK, of the city of Chicago, in the county of Cook and State cf Illinois, have invented a new and useful Improvement in the art of Skating by the use of two wheels as runners, which I have named the Mentupede and I do hereby declare and make known that the following is a full; clear, and'exaet description of the same, reference being made in so doing to the accompanyingr drawing and letters and figures marked thereon, which forms part of this specification.

My said invention consists in a novel mechanical device to be attached to the foot of a person in such a manner as ,to be perfectly secure and at thesame time take the place oi' a skate, as a healthy exercise, being perfect-ly safe and very easy to manage. By the use of two wheels of suitable sizes the friction amounts to hut little, so that the device may be used on the streets and walks, and run over uneven snrfaces at pleasure, substantially as hereinafter described.

To enable those skilled in the a'rt to understand how to make and use my invention, I will proceed to describe the saine with particularity, reference being made in so doing to the aforesaid drawing, in which- Figure l represents a side elevation of my invention Figure 2, a vertical rear view or heel thereof taken at the line :u in tig. 1;

Figure 3 is a bottom view of the foot-stand C, showing the method of securing the supportB to the same Figure 4 represents a bottom view of the vibrating support S;

Figure 5, a view of the pivot-bolt G;

Figure 6 is the shape of the spring c and Figure 7, a perspective view of the friction-lever c and spring al.

Similar' letters of reference in the different figures indicate the same parts in my invention.

A represents a foot secured to the foot-stand C, fig. 1, by means of suitable straps and buckles M L H, or other' suitable devices may be used for the same purpose ifdesired. Said straps M L may be secured to the foot-stand C, iig. 1, by rivets, screws, or slots.

B represents the stationary or main support for the wheel Ne, vibrating support and wheel S and N.

Said support B is secured to the bottom of the foot stand C by rivets or screws, as shown in figs. 3 and 4, or otherwise, as desired.

It will be observed that the support B is provided with a socket, into which the vibrating pivoted support S is made to t in such a manner as to form a hinge or joint, and both parts B and S, figs. 1 and 4, are connected and held together by the pivot-bolt G passing through the top of the footstand C and into the support B, then through the vibrator S, .ind held into place by a serew-thread or any other suitable device at v, as shown by the red dotted lilies in iig. 1.

The vibrating support S is provided with a lug or projection, b, against which the spring a', figs. 1, 3, and (i, acts in such a manneras to keep the vibrator and wheel N in a straight line with the wheel Ne when the machine is raised and in a hanging position. It will be observed that the course of the machine -while running may be changed, at the will of t-he operator, by twisting the foot-stand C s'o as to throw the heel of the same to the right or left-of the center, thus moving the steering-wheel out of line, causing the machine to curve, as more clearly shown in iig. 3 by the dark dotted lines N N N and S S S. N e is the stationary position of the front wheel, indicated by the dark dotted lines.

The Wheels Ne and N may be inade as shown in fig. 1, or in any other style desired, of any suitable mate rial, and provided with suitable bands or tires of brass, iron, steel, wood, or vulcanized India rubber, as desired.

rlhe aforesaid wheels Nc and N are provided with lugs or journals at their centers, and the said journals revolve in suitable boxes or bearings, as shown in figs. 1, 2, and 4 at o o thereof; or insteadV of said journals the wheels may revolve on a stationary bolt or axle, or any other suitable device.

The projection P on the aforesaid vibrating support S may befextended up above thc-top of the wheel N, and be provided with friction-rollers acting against the bottom of the aforesaid foot-stand C, for the pur pose of preventing said wheel coming in contact with the Same.

The spring aJ is fastened and secured to the aforesaid foot-stand by means of rivets, screws, or otherwise, as desired; or instead of the aforesaid device a suitable spring may be arranged on and secured to the vibrating support S, and the same act against the foot-stand C or the support B, for the purpose shownA in figs. 1 and 3.

E represents a curved metallic Vstripshaped to tit the calf of the leg, and provided with a suitable strap, H, secured to one end of the said strip E by rivets or otherwise, as desired. Said strap H may be provided with suitable button-holes or hooks, as shown in iig. l, for the purpose of elasping and securing the two parts around the leg.

It is a button or knob for holding one end of said strap. Suitable buckles or clasps may be used instead of the above device, if desired.

The said strip E has attached to its ends the upper end of the brake-levers F F F, by means of rivets, as shown iu gs. 1 and .2. The said brake-levers are pivoted to the heel-support D at t li, thereby forming a fulcrnin thereof for the loop or fastening on the lower end of the levels F F at h h, gs. l and 2, to which is fastened the ends of the cord or chain I, as

shown. l

Said cord or chain passes over grooved pulleys f f, pivotcd at g g, figs; 1 and 2, as shown, then through a loop, P, in the friction-lever c. Said friction-lever is pivoted at e, as shown by the dark dotted lines in fig. 1. It will be observed that by moving said brakelevers .at the top forward or backward, as the case may be, that h h draws on the said cord or chain I, thus forcing the lower end or rubber part of said friction-lever against the said wheel Ne, thereby retarding its motion. Y

,Said lever c is provided with asuitable spring, (l, as shown in figs. 1 and '7, which acts against the footst-and G in such a manner as to keep the rubber part of said lever away from the wheel when the cord or chain is slacked.

Having described the construction and operation of my mentupede,

y 1. The combination and arrangement of the footstand C, straps or 'clasps M L, main support B, yibrating pivoted support S, lwiaeelsNe N, having suitaud pivot-bolt G, friction-lever c, and its spring d, operating substantially as and for the purposes herein shown and specified.

2. The metallic strip E, suitable strap H, knob R., brake-levers F F, heel-snpport D, and fnlcrums i i, oord or chain I, loop or clasp h, pulleys f f,operating substantially as and for the purposes herein describe( and set forth'.

3. The combination of the foot-stand C, stationary support B as arranged for the front wheel Ne, pivoted vibrating support S as arranged for the re ar wheelN, double-acting sp1-ing a, and lug b, for the purposes herein shown andspecified. Y

4.` The joint and bolt G arranged between the front wheel Ne andrear Wheel N.
