PATENT OFFICE.
CHRIS RAITZ, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT' IN PARLOR-SKATES.
Specification forming part of Letters Patent No. 117,329, dated July 25, 1871.
To all whom it may concern: v l
Be it known that I, CHRIS RAI'rZ, of San Francisco, in the county of San Francisco and State of California, have invented an Improvement in Parlor-Skates; and I do hereby declare that the following is a full and exact description of the Same, reference being had to the accompanying drawing and to the letters of reference marked thereon.
My invention relates to that class known as parlor or roller-skates, and has for its object an improved device for turning or cramping the rollers. This is effected by means of a plate which is secured to the foot-stand, and is'provided with an angular slot, into which the standard which Supports and turns the axles is Secured so as to turn about its axis. This movement brings the wheels on one side nearer together and thus allows the skate to move in a curve. The lower end of the Slotted plate is 4formed into a curve with a projecting shoulder, and the upper part of the standard has a similar Shoulder, the two being so arranged as to limit the motion in either direction. A steel or other spring is set in the block and presses against the upper end of the angular arm of the standard, and returns the wheels to place when the pressure is removed.
Referring to the accompanying drawing for a more complete explanation of my invention, A is the foot-stand or skate-block, and B B are metal plates rinly secured to the footstand on its lower side and sufficiently near the ends to bring the roller into the proper position when they are attached. The plates B are made to project downward a suflicient distance to admit of the formation of an angular slot, C, which extends up through the top. The standard D may be formed with the axle, or in other suitable manner, and extends up vertically to the lower part of the plate B, from which point it is continued as a flattened plate or bar, E, which is fitted into the slot C in the plate B. Apin, c, secures the standard by passing through the sides of the plate B and the bar E, as shown, so that the standard can move about its center or point of support. As this motion takes place at an angle, it will bring the rollers on either side nearer together by throwing the axles out of parallel and into converging lines. ln order to prevent too great a motion from side to side, the lower end of the plate B, which is curved, has a shoulder, c, formed at each Side, and a correspon ding shoulder, d, is form ed at the top ofthe standardjust at the base ofthe inclined bar E, and when the turn is sufcient the two will come into contact and prevent a further motion. In order to return the standard to its vertical position after the pressure has been removed, a steel or other spring, F, iS secured inside the plate B so as to press upon the upper end of the bar E. As this end is square, one corner or the other will be elevated by the turning from Side to Side, and the spring will. press upon that corner and thus restore it to its position when the pressure isremoved. It will be observed also, that, from the peculiar construction of the parts, bearingsur faces are formed atom', so that the strain is necessarily taken from the rivet or securing-pin.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1S-
The combination of the plate B with its shoulder c, and standard D with shoulder d, and bar E with the spring F, the parts B E being provided with bearing-surfaces 0c x for the purpose of relieving the rivet-pin a., as described.
In witness whereof' I have hereunto Set my hand and seal.
