ELVOOD C. PHILLIPS, OF RICHMOND, INDIANA.
ROLLER-SKATE.
SPECIFICATION forming part of Letters Patent No. 309,089, dated December 9 1884.
` Application filed May 31, 1884.
To CLZZ whom t may concern:
Be it known that I, ELWooD C. PHILLIPS, a citizen of the United States, and a resident of Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification.
My invention relates to roller-skates.
The object of my invention is to provide a suitable hanger for connecting the rolls to the foot-board ot' the skatenfirst, so that it can be readily detached; second, so that the tension of the spring can be readily adj usted so as to obtain a uniform pressure upon the entire surface of the spring, all of which will be fully set forth in the description ofthe accompanying drawings, in which- Figure l represents a perspective view of my invention; Fig. 2, a longitudinal vertical section 5 Fig. 8, a perspective view ofthe conipressing-stirrup; Fig. 4, a perspective view ofthe upper springfseat.
A represents a roller-bracket, which is represented as cored out with an opening in the center to lighten the metal.
B represents a shaft on which the rollers are journaled. It is rigidly secured to the arms of the hanger-bracket A.
C represents the bottom face of the bracket A, which forms the lower seat of the spring.
c represents a pivot which journals in one of the pendent arms, D, of the bracket E, which bracket is rigidly secured to the under side of the usual foot-board.
d represents the secondary downwardlyprojecting arm, in which the detachable gudgeon e journals. This gudgeon e seats against a coiled spring, F, in a-socket-board in the plate C. Pivots c and c form the transverse rocking-axes of the foot-board.
The object of the seating of detachable gudgeon or stub e upon the spring F is to allow the frame A to be detached from the hangerbracket E by pressure applied upon the outer end of the gudgeon c, forcing it and the spring F inward until it is released from the journalbearing in the pendent arm d, when the frame A can be readily detached from the frame E by the turning of the gudgeon c in its tapered In orderto allow of this movement, I usually make the gudgeon c of smaller di (No modeLl ameter than the j ournal-bearing in the pendent arm D. A modification of this mode of attaching the frame A to the frame E could be made by having both gudgeons seat upon springs; but one detachable and yielding gudgeon is sufficient for the purpose. l
H represents a lateral-adjusting oscillating stirrup, preferably of link shape, the arms of which embrace the pendants D d.
I represents a springloop which is hinged at one end to the front arm, J, of the link H, and the other end rests ina seat, K, formed on the under side of the bracket E, which forms the front bearing-support of `the stirrup H. The rear bearing-support is an adjustable screw, L, which taps in screw-threads formed in lug Z at the rear end of stirrup H. The inner end of thescrew bears against the pendent arm D and holds the stirrupH in position .for supporting the spring.
M represents a rubber spring, which is formed of a rectangular piece of rubber, and rests upon the lower bearing, C. The upper bearing of the spring is formed ofa loose plate, N, which is provided on the lower surface with flanges a to hold the spring in position.
Instead of employing the flanges n, a spud, m, may be employed, which is forced into the rubber to hold it in position.
O represents ribs formed on the upper face of the plate N, which ribs project upward between the arms of stirrup H.
In order that the plane of plates N and C may be maintained in a parallel position, the seat-plate N is made rounding upon its under side, so that it will rock upon the arm of stirrup H.
VVhen it is desired to increase the tension of spring M, adjusting-screw L is turned inward. The point, pressing against the pendent arm D, draws stirrup H backward, lowering the front end, which hinges upon the flexible, plate I, thereby lessening the space between the seatplates N and C, thereby compressing the spring M. This method of adjusting stirrup H and seating the spring M upon the rocking plate N preserves the parallelism of the faces of seats N and G and gives a uniform or equal compression to all parts of the rubber spring. This is a very important advantage, for if the seat N were rigidly secured to the stirrup H IOO one side of, the spring would be compressed more than the other, which causes the rubber to Wear out of shape, and does not give proper yielding motion to adjust the foot-board as it is rocked sidewise by the wearer. rIhe elastic or spring loop Iis also advantageous, as it gives additional yielding motion to the foot-board, and renders the parts much less liable to be broken under the jars and strains to which the skate is subjected in use.
By constructing the hangers and connecting parts in the manner here shown, I produce a much more even and uniform motion of the spring, as Well as securing amore elastic support for the rollers.
An inferior modification of my device would be to have theloop I hinged to both the hanger E and stirrup H. This modification, in combination with the loose adjusting seat-plate N, Wouldmaintain the parallelism of the springseats, but Would not secure as good ayielding connection of the parts as the form shown in the drawings.
I do not Wish to confine myself to the forms of spring for supporting the detachable gudgeon c, as a rubber cushion might be employed in lieu of the spiral spring.
Another modification of my invention would be to provide forked hangers D d with the reciprocating stirrup H, placed between the forks of the-hangers and supporting the adjustable seat-plate N 5 but this modification would require a larger amount of metal to obtain the same strength.
I have shown in the drawings but a single hanger-frame for journaling, say, the front pair of rollers to the skate-board. It is obvious that tWo such hangers and journal-supports would be required-one upon the front and the other upon the rear ,end of the skateboard, in the usual manner.
I claiml. In combination with the axial bracket A, the detachable gudgeon e, spring F, and gudgeon c, for detachably journaling the hangerframe E tothe bracket A, substantially as speciiied.
2. In combination with the detachable hanger-frame E, a roller bracket-frame, A, and hinged stirrup H, adjustable springseat N, and stationary seat C, substantially as specified.
3. In combination with the bracket A and seat C, the hanger-frame E, adjustable springseat N, and stirrup H, detachably secured to said fratrie E by means of a yielding loop, I, substantially as spec-ined.`
4. In combination with the bracketfraine E, having the pendent journal-arms D d, the stirrup H, surrounding the said arms, adjustingscrew L, and loop I, for adj Listing the tension of the spring by the lateral movement of the stirrup H, substantially as specified.
In testimony whereof I have hereunto set my hand.
ELWOOD C. PHILLIPS.
