i To all whom it 71trtyc0n0cr7t:

Be it known that I, ELIAS E. RIES, a citize of the United States, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Automatic or Self-Acting Cycle or Bicycle Skates, of which the following is a specification.

My invention relates to apparatus for individual locomotion, and has for its object to provide means forproducinga rapid and continuous motion or travel over ordinary surfaces or roads by simply transferring the weight of the body from one foot to the other in a manner similar to the ordinary act of walking. I accomplish this object by con-. structing an automatic or self-acting skate comprising, broadly speaking, two cotiperative parts,one of which is provided with means of attachment to the foot or shoe of the wearer and constitutes what may be termed the foot-plate of the skate and the other of which constitutes the framework or, as hereinafter termed, the base-plate, which carries the driving mechanism, the parts being so constructed. and arranged that a reciproeating motion of the foot-plate is converted into a forward motion of the skate, and Ialso provide means for normally separating the foot-plate from the base-plate, so that as the weight of the body is thrown to one side and the foot-plate on the other side is relieved of this weight this foot-plate automatically rises or separates itself from the base-plate.'

In the accompanying drawings, Figure l. is a side elevation of my improved skate, illustrating the position of the parts when the foot-plate isdepressed andshowing the driving mechanism in dotted lines. Fig. 2 is a side elevation of the rear portion of the skate, showing the position of the parts when the foot-plate is in its raised position. Fig. 3 is a rear elevation of the skate, showing the driving-gear. Fig. 4: is a sectioual'rear elevation of the skate on line a; as, Fig. 1, showing the front or pilot wheel. Figs. 5, 6, and 7 are views similar to Figs. 1, 2, and 4, respectively, showing a modified construction for a two-wheeled or bicycle skate. Fig. 8 is a detail view of the clutch mechanism shown in Figs. 1, 2, and 5; and Fig. 9 shows a slight modification of this device.

Referring to Fig. 1, the skates herein illustrated have the general appearance of ordinary roller-skates. They dider from these, however, in that the rear wheels (or wheel) 1 and the forward wheels (or wheel) 2, which in my skate constitute the-driving and pilot Wheels, respectively, are not mounted upon the foot-plate 17 directly, but run between bearing-forks 22 24 of any suitable form, carried by the independent base-plate or frame 18, with which the foot plate or rest 17 is connected by a pivotal or hinge connection of proper character to permit a bodily lip-anddown movement of said foot-plate with reference to the base-plate or frame. As an example of such connection the drawings show a pin i, which passes through ears on the forward end of the base-frame 18 and through lugs or ears 23, projecting downward from the foot-plate.

In this description and following claims the term base-plate will be used as: meaning any frame or structure provided with or affording bearings for the wheel or wheels of the skate and also a support for the foot plate or rest, by which latter term is meant any support adapted to be secured to the foot and affording a rest or support therefor, which will under the weight of the user be moved bodily downward between the base plate or frame.

The foot-plate 17 as well as the base-plate 18 are preferably made of thin sheet iron or steel, although it is obvious that they maybe made of wood or any other material. The foot-plate, as illustrated, is provided with adjustable clamps, such as are generally used on. ice-skates, for ready attachment to and removal from the shoe of the wearer. Under ordinary conditions of use the foot'plate 17 is normally kept separated or at a distance from the base-plate .18 by the action of the flat spring 3 or its equivalent, which tends to hold the two portions of the skate apart, so as to cause them to diverge at the rear and to assume the relative positions shown in, Fig. 2 when there is no pressure on the footplate. ll prefer to provide, however, at the rear of the foot-plate a link or cam-lever 5,

having a snap-spring 6 and adapted to engage with a locking-catch 7, formed on the rear end of tho base-plate in such a manner that the two portions of the skate may be held rigidly together wheirit is desired to throw the driving mechanism out of gear. The camlever 5 is in the form of a thumb or finger lever, so as to permit of ready manipulation while the skate is on the foot, and is, furthermore, made of such shape as to serve when elevated as a pantaloon or dress guard.

To the under side of the foot-plate 17 at a point 'directly or approximately under the heel is secured a lug 16, (see Figs. 1 and 3,) whose pin engages with the upper end of a connecting link or rod 8 and passes through a suitable guiding and steadying slot 14 in the base-plate18 and connects at its lower extremity by means of the pin 21 with the free ends of the driving links or forks 9 9,

whose inner ends are journaled loosely upon the driving-axles. Attached to the drivinglinks 9 9 by-means of the pin 20, preferably at or near their outer or free ends, isa flexible strap or band 11, of leather or other suit able material, which extends partly around the periphery of a drum 26, to which drum the other end of the strap 11 is fastened at 19, as indicated more clearly in Fig. 8. This drum 26 when the construction shown in Fig. 8 is used is mounted loosely upon the driving-axle independently-of the driving-links 9 9 and contains a coiled spring 9, one end of which is secnredto the inner periphery of the drum-casing 26, the other end being attached to'a stud 22", secured to the driving-wheel fork (or forks) 22, the drum-casing being provided with a curved slot 26, designed and adapted to clear the stud 22' when the drum is rocked about the driving-axle under the opposing influence of the driving-links 9 9 and spring 9. 1 prefer, however, instead of using the spring 9 and the strap 1 1 for moving the drum to employ the arrangement shown 'moreclearly in Fig. 9, in which the drivinglinks 9 9 form an integral part of or arerigidly secured to the casing of the drum- 26, so that the drum is directly and positively operated or rotated in both directions by the links 9 9 when the connecting-rod8 is raised and depressed by the motion of the foot-plate 17.

Within the casing of the drum 26 and keyed firmly to the driving-axle is a friction pulley or gear 12. The face or periphery ofthis pul- 'ley may be provided either with a covering 12, of leather or other yielding material, as shown in Fig. 8, or with ratchet-teeth 12", as shown in Fig. 9. A pawl or pawls 10 10, fastened to the inner side of the drum, Fig. 8, or to the inner side of the links 9 9, Fig. 9, and pressed forward by the pawl spring or springs 25, bear upon the face of the pulley 12 in such a direction that when the connecting-rod 8 is depressed they will operatively engage with the face ofthe driving-pulley,

so as to rotate it, together with its driving the influence of acquired momentum on the part of the user. It will therefore be apparent that the driving axle and Wheels are at all times free to move or rotate in a forward direction, but are locked against backward rotation.

, The construction of the driving mechanism illustrated in Figs. 5,6, and 7 of the drawings is similar to that just described with the exception that there are used with the'bicyole-skates two drums, oneateach side of the single driving-wheel therein shown, (in order the better to equalize and distribute the pressure,) and two pairs of driving links or forks, whose connecting-rods 8 engage with a .pin 15, mounted between the two depending cars 16 16, formed in this instance byturning down the metal at either. side of the heel-plate, as shown in Fig. 6. On the body of the connecting rod, pin, or shaft 15 are mounted cushions or bufiers 13 13, of rubber or other yielding material, for the purpose of limiting the downward sweep of the foot-plate 17 and to serve as a cushion between the foot-plate 17 and the base-plate 18 at the end of each stroke or movement of the foot-plate, as well as to increase the elasticity between the foot and base plates when the two parts are united by the link or cam-lever 5. The connecting rod or rods 8 are also provided with a pin or with a common shaft 27, which limits the upward sweep of the foot-plate and which is either itself provided with a similar cushion or preferably bears against a fixed cushion 14:, extending across the under surface of the base-plate in dine with the guidingslot,

through which the connecting rod or rods pass. The stroke of the connectingrod 8 is in practice so adjnsted'with respect to the diameter of the driving-drum 26 and the ra- ICC dine and leverage of the driving-links 9 9 that without an. undue lifting or separation of the foot-plate 17 from the base-plate 18 the driving wheel or wheels will be forced to turn one or more complete revolutions or, if proportioned as shown in the accompanying drawings, a definite part of a revolution each time the foot-plate 17 is depressed. It will be evident that by a suitable arrangement of the driving-gear any desired ratio of revolution for a given motion of the foot-plate may be obtained.

In my four-wheeled cycle-skate shown in Fig. 1 the rear or driving wheels are placed somewhat behind and close to the sides of the heel-support of the foot-plate, thus permitting the latter to rise and fall between them. This construction enables me to use drivingwheels of comparatively large diameter with- I out unduly raising the center of gravity of thdwearer of the skates and without obstructing the freedom of his movements by reason of the proximity of and the possible interference between the driving wheels of both skates, due to the natural or usual divergent position of his foot. Thepilot wheels are preferably placed under the forward part of the skate well to the front and may therefore be of smaller diameter. The distance between the two wheels of each pair in this type of skate is sufficient to give a broad and stable base or support to each foot.

In the two-wheeled or bicycle skate modificationor type of my invention illustrated on Sheet 2 the driving-wheel is necessarily in the longitudinal center of the skate. The base-plate is therefore provided with an opening or slot to permit of the free passage through the same of the upper portion of the driving-wheel, which latter is reduced in diameter to'a sufficient extent to prevent the foot-plate 17 from coming in contact with it. The operation of my automatic or self-act'- ing cycle-skate is as follows: When one foot is lifted, as in the act of a slight forward step, the pressure on spring 3 is relaxed, thereby causing it to separate the foot-plate and baseplate and to lift the connecting-rod 8 until the links 9 and drum 26, with its clutch mechanism 10, are moved backward and set in the position shown in Fig. 2. On now throwing the weight onto this foot the foot-plate commences to descend bodily with a considerable force toward the base-plate 18, moving the connecting rod or rods 8 down with it and causing the links 9 9,either directly or through the strap 11, to revolve the drum 26 with its clutch devices 10 and driving pulley or ratchet-gear 12. The downward motion of the foot-plate is thus converted'by means of the impulse imparted to the fixed pulley 12 into a direct rotary motion of the drivingwheels 1 1, that drives the skate forward with a positive action and with a speed dependent, primarily, upon the weight of the pedestrian and upon the extent and suddenness with which the weight is transferred or applied to the foot-plate and, secondarily, upon the diameter of the driving-wheel and the ratio or leverage which the clutch or driving mechanism bears to it. Since the energy or mo-- tive force represented and imparted by the weight of the pedestrian during the travel of the foot-plate is far in excess of that required to move the skate forward a distance corresponding merely to the initial or positive motion given by the same to the drivingwheels, it followsthat after the completion of the actual stroke the fixed pulley and the driving-wheels will continue to revolve and move the skate forward after the foot-plate has come to rest upon the base-plate, so that the pedestrian will be carried forward under the influence of the initial momentum imparted to the driving mechanism and to himself adistance equal to a number of complete revolutions of the driving-wheels before the skate finally comes to a standstill. It is not essential for propulsion that the skate be lifted clear of the ground at each step or thrust, (although this may be done,) it being-necessary only that the foot be raised or the. heel tilted sufiiciontly to permit the foot-plate to become elevated for the whole or-any fractional part of its normal stroke.

I may in some instances make provision to facilitate climbing hills, as by arranging the pilot-wheel bearing 24' so as to be vertically adjustable within grooves 28 in the front fork '24, (see Sheet 1,) whereby the pilotwheels can, if desired, be readily raised or lowered, so that the level of the base-plate 1S, and that of the foot-plate 17 (when at the lower end of its stroke) may be kept in asubstautially horizontal position irrespective of the inclination of the grade or grades that may be encountered.

It may sometimes, be desirable to throw the driving mechanism out of action and to use my skate as an ordinary roller-skate. For this purpose the cam-lever 5 when thrown into engagement with the catch 7 locks the foot-plate and base-plate together, so that no motion can be imparted to the connectingrod 8. t
