G. RUSH,J1-. Roller Skate;
No. 229,011. Patented June 22,1880.
MPEI'ERS. PHDTOLJTHGGRAPHER. WASHINGTON. D. C.
UNITED STATES PATENT OFFIC GEORGE RUSH, JR, OF PHILADELPHIA, PENNSYLVANIA.
ROLLER-SKATE.
SPECIFICATION forming part of Letters Patent No. 229,011, dated June 22, 1880.
Application filed February 24, 18 80.
To all whom it may concern:
Be it known that I, GEORGE RUsH, Jr., of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Roller-Skates, (which has not been patented to me in any foreign country, nor has it been patented -with my knowledge by or to any person in any foreign country,) of which invention I do hereby declare the following is a sufficiently full, clear, and exact description to enable others skilled in the art to make and use the said invention, reference being had to the drawings annexed, and the letters of reference marked thereon.
My invention relates to that class of rollerskates in which the inclining of the sole latererally by the motion of the foot of the wearer causes the axles of the wheels or rollers to change from a parallel position to an inclined position toward each other-,and thus cause the skate to roll in curved lines.
This invention consists in a novel, cheap, and useful mode of making the axles and applying the springs thereto, so that the force or resistance of the springs is readily adjusted and not liable to accidental change of adj ustlnent.
Referring to the drawings, Figure 1 shows a front elevation; Fig. 2, a plan of the skate in inverted position; Fig. 3, a vertical section in the plane indicated by the dotted lines :10 at in Figs. 1 and 2, and Fig. 4 a section in the plane indicated by the dotted line 3 y in Fig. 3.
The same letters of reference apply to the same parts in the several figures.
A represents the skate-sole, which may be provided with any of the known means of attachment to the shoe or foot of the skater.
B and B are spindles or studs projecting obliquely downward from the bar 0, which occupies the same position in relation to the sole A as the runner of an ice-skate.
D and D are axles turning upon the oblique spindles B and B, and bearing rollers marked E, E, E and E The axles D and D are formed in two parts, the portion F, between the rollers, being a single piece and tubular, and
receives a cylindrical bolt, G, which, fitting through both wheels and the tube in the piece F,is secured therein by a washer, H, and linchpin J. The part of the axle marked F should be made of ductile metal, and is provided with projecting arms or levers (marked K and 'K) formed in one piece therewith.
Through the centers of the broad and fiat ends of the levers K and K a screw, L, is passed, having a head bearing against the outer surface of the lever K, and screws into a nut formed in the lever K. The elfect of turning the screw L in one direction is to bend the levers K and K toward each other. If turned in a reverse direction it permits them to be spread or bent apart.
Upon the screw L, between each of the levers K and K and the bar G, is placed a spring, M, of rubber or other elastic material.
By tightening the screws L the levers K and K are drawn toward the bar 0, and theinte'rposed springs M M are compressed, and their elastic force or resistance augmented. By loosening the screws L it is diminished. They thereby adjust the resistance of the springs to the canting of the skate-sole and the turning of the axle D and D on the spindles B and B, by means of which the skater controls or changes his course.
The advantages of this invention are cheapness and simplicity of construction, the avoidance of loose parts and the rattling noise consequent thereon, and an easy graduation of the resistance of the spring to the weight of the skater.
Having fully described my invention, what I claim therein as new and useful, and as original with myself, is-- The combination, in roller -skates, of the axles D and D, provided with ductile metallic arms K and K, having the adjusting-screws L, with the springs M -M M M and bar G, as
and for the purpose set forth.
