ROLLER-SKATE.

SPECIFIGATIO1\i' formingpart of Letters Patent No. 527,164, dated October 9, 1 894. I Application filed July 6,1894. Serial No. 516,781. (No model.)

To aZZ whom it may concern.-

Be it known that I, J OHAN ALBERT SEGER- BERG, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Roller-Skates; and I do hereby declare the following to be a full, clear, and exact description of the in-' vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in roller skatesgand its object is to provlde a skate of a light and inexpensive construction, which will accommodate itself to the movements of the feet andby the use of which the skater will be enabled to turn without undue strain either upon the ankle or upon the skate itself.

The invention also contemplates the pro-- vision of a reversible tire, together with other details of construction, all of which will be hereinafter fully set forth.

In the accompanying drawingsI have illustrated a skate embodying myimprovements, in which drawings- Figure I is a side .elevationof the skate, and Fig. II is a front view of the same. 4 Fig. 111 isa transverse, vertical section taken axially through the skate in the plane indicatedby the line at in Fig. I, and Fig. IV is a similar section taken through-the padded ankle brace. Fig. V is a section of the tire, showing the reversible character of the same. Figs. III, IV and V are drawn to a scale larger than that of Figs. I and II. I i

In the views 1', 1, represent two wheels con structed similarly tothe wheels of a velocipede, and having each a metal rim 2 provided with a V shaped groove in its outer face, wherein fits one angle of a rubber tire 3, which is, in section, of a triangular form, having one curved exterior face and two plane faces, as clearly seen in Fig. V. By constructing the tires in this manner, it is evident that after they have become worn at one angle they may be removed from the rims 2 and reversed, the tire on one wheel being substituted for that on the other.

The

wheels

1, 1 are mounted on the 0pposite ends of a tubular axle 4, and the ends of the axle are set in difierent planes, being in clined down'ward'at their outer extremities, so that the plane inner faces of the tires 3 contact withone another, as clearly seen in Fig. V, thereby rendering the two wheels at their point of contact with the ground subderstood by inspection of Figs. II and V.

The axle 4 is formed in two sections, bypreference, and in order to secure these sections together in an adjustable manner, each section is provided at its inner end withadepending, tubular L.-shaped portion 5. The lower, horizontal arms 5', 5, of these L-shaped portionst5 extend toward one another, and are provided with opposite interiorscrew-threads stantially one wheel, 'aswill be readily un- I to receive the oppositely screw-threaded ends of a tie-rod or b21126 as clearly seen in Fig. 1H. By turning' the tie-bar 6 it' is evident the wheels 1 may be set nearer together or farther apart, as desired. Thus it will be seen that a wedge-shaped space is provided between the two wheels 1 and in this space,

which extends below the axle of the wheels, is arranged the foot-support or shoe 7. The shoe has a metal bottom plateS'resting on the lower arms 5' of the axle, andat its sides slotted metal straps 8', 8 are provided, the ends of which are adj ustably secured to the portions 5 of the axle.

In order to still further strengthen the At their outer ends,

ing portion"5 of the axle, ands'crews at its lower end into an oppositely threaded sleeve 10 guided in a bearing piece 11 projecting from the angle of the parts 5 and 5' of the axle, and screwingat its lower end into a screw-coupling 12, arranged below the hori zontal portion 5' as clearlyseen in Fig. III. The screw-

couplings

12, 12, are connected to one another by a tie-bar 13, havingo'ppo-' sitely screw-threaded ends,and by turning said tie bar the screw-

couplings

12, 12, may

be drawn nearer together or thrown farther apart so as to give greater strength to the axle at its outer ends. In order to support the heel and toe portions of the foot-support or shoe 7, braces 14, are provided, each screwing at one end into one of the screw-couplings 12 and at its other end into a socket formed on the under side of the bottom-plate 8 of the shoe 7. There are or will be, by preference, four of these braces 14, a heel and a toe-brace at each side of the shoe.

In order to secure the skate in place on the foot, shoe 7 is provided with a suitable securing device 7' passing over the instep; and to further secure the skate, as well as to brace the ankle of the skater, and to prevent contact with the upper portions of the wheels in turning, I provide ankle braces comprising pads 15, having slightly tapered or conical sockets 16 to receive the upper ends of tubular supporting rods 17. The pads may be locked fast by means of locking nuts 18 screwing on the rods 17 over the upper ends of the tubular sockets 16. When said nuts 18 are loosened, pads 15 may be turned around so as to receive the ankle; and when said pads have been turned back so as to bear on opposite sides of the ankle, the nuts 18 may be tightened to lock the padsin place. The rods 17 are each provided at the lower end with a perforated lug 19, through which passes a screw 20, serving to secure the rod to the inner end of one of the sections of the axle l.

The rods 17 swing on the screws 20 as pivots,

thereby accommodating themselves to the movements of the feet. In the opposite side of each rod 17 are formed two openings through which pass the threaded ends of a bent wire or rod 21, the ends of which pass through slots 22formed in an arm or tongue 23 projecting substantially at right angles from a sleeve 24 loosely fitting the end of the axle 4 just inside the wheel hub. Thumb nuts 25 screw on the ends of wire 21 so that when said nuts are turned, rod 17 is clamped firmly to tongue 23. Thus it is evident that when said screws 25 are loosened, rods 17 may be adjusted so as to stand at greater or less angles to one another, and while held in the desired position, may be clamped fast by tightening screws 25.

In order to equalize the strain upon the wheels 1 and axle 4 in turning, and to prevent the whole weight from being thrown upon one wheel and one end of the axle,

whereby the skate might be damaged or broken, I preferably provide the rim 2 of one of the wheels with athin annular metal strip or rib 26, projecting at right angles from the inner plane face of the rim 2, as seen in Figs. II and V, and fitting, at the point of contactbetween the two wheels into a corresponding annular groove 27, formed in the rim of the other wheel, as clearly seen in Fig. V.

My invention is susceptible of considerable modification without material departure from its principles and therefore I do not wish to limit myself to the precise construction and arrangement heroin shown.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. Aroller skate consisting of two wheels set at angles to one another, their rims touch ing each other at their point of contact with the ground.
