UNITED STATES PATENT OFFICE.
WILLIAM H. BLISS, OF NOWICH, CONNEGTIGT.
SPECIFICATION forming part of Letters Patent No. 244,372, dated July 19, 1881,
Application filed J une 11, 1881. (Model.)
To all lwhom it may concern:
Be it known that I, WILLIAM H. BLIss, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented new and useful Improvements in Roller-Skates, of which the following is a specification.
My invention' relates particularly to devices to allow of turning the rolls in guiding the skates and yet positively stopping them at certain points, While sufcient yield is allowed by a spring acting before the positive stops are engaged with each other.
In the accompanying drawin gs,Figure1 represents a side elevation of a roller-skate with my improvements applied thereto. Fig. 2 is a view of the hanger detached from the soleplate.
A represents the sole-plate or platform. h is the attaching-plate of the roller-han ger.
b is a sleeve, attached by a connecting-piece to the sleeve g, which carries the roller-pintle.
o c are small projecting arms, one of which is located upon each side of the sleeve or coupling-eye b.
d d are shoulders or stops formed on the long depending part of the hanger, one on each side of each hanger of the skate-rollers.
e e are corresponding stops or shoulders on the sleeve b of the upper part of roller-pintlecarrying piece. f j' are the pintles or journalrods holding the roller-carrier.
a a are plate-springs, secured to the soleplate by the same screws that secure the part h of the attaching-plate of the hanger.
My invention consists in the stop-shoulders respectively located upon the depending part of the hanger and the sleeve forming a part of the roller-carryin g frame, aud combining therewith the plate-spring and the projecting arms of the sleeve or coupling-eye b.
It will be seen that the arrangement of the stop-shoulders is such that a limited amount of motion or play is allowed in turningthe direction of the skate, while too great motion is checked at once by the stop b on the couplingeye striking the stop-shoulders d on the depending part of the hanger. In order that the turning motion be not too easily made, or made unv intentionally when the skater is not trying to turn his direction, the platesprin g a is introduced, bearing at its free end upon arms c c projecting from the coupling-eye b. 1t will be seen that thus, as force is gradually applied upon either the one side or the other of the foot in turning, the roller-carrying part yields gradually, and in the end the position-stops alluded to prevent any further turning. Without the springs the stops would too suddenly check the turning motion, and without the position-stops the checking is not done with sufficient promptness and positiveness.
I am Well aware that stops of various sorts have been used for the same purpose as Inine; but I am not aware of any that are located as nnine,l so as to be so readily constructed in forming the hanger and coupling-eyes.
I am also aware that Winslow and others use rubber springs to serve as a yielding stop, and I do not claim such. I have endeavored to provide a stop that shall not, by the wearingof the rubber or its exposure to weather and oil, change from time to time, as it wears the point at which the turning must stop.
I do not claim, broadly, the projecting arms c c.
What I claim as my invention is- 1. The abrupt stops or shoulders located upon the depending part of the hanger and the sleeve or coupling-eye, respectively, all as and for the purposes set forth.
2. The combination of the stops or shoulders on the hanger and coupling-eye, respectively, and the plate-spring acted upon by the arms c c upon either side of said coupling-eye, all as and for the purposes set forth.
