ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 298,110, dated May 6, 1884.

- Application filed February 5, 18H4. (No model.)

.To al] whom it may' concern.:

Be it known that I, CHARLES F. Monsn, of

Somerville, in the county of Middlesex and State of Massachusetts, \have invented certain Improvements in Roller-Skates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this speciiication, in which- Figure 1 represents a pair of skate-rollers with their connecting-axle constructed in accordance with my invention and applied to one of the bearings on the under side of a skate, one roller being in section and the other in elevation. Fig. 2 is a perspective view of my axle; Fig. 3, a perspective of the adjustable journal which screws thereon. Fig: 4 -represents the key by which .the said journal, when adjusted, is locked upon the end of the axle. Fig. 5 is a perspective of one side of the box, located in the wheel in which the axlejournal bears. Fig. 6 is an elevation of the other side ofthe said box. Figs. 7 and S are elevations of the opposite sides of the outer face-plate, which holds the j ournal-box in place within the wheel. Fig. 9 is a view of one side of the inner face-plate, by which the journal is retained within the wheel-box. i Fig. 10 is a view of the opposite side of said inner plate. Fig. 11 is a section representing the lubricat ing-passages. Fig. 12 is a section through the spring-actuated pin for keeping the outer faceplate in place; Fig. 13, an elevation of the inside of the wheel with its box and plates removed. Fig. 14 is a view of the spannerwrench which I employ in securing the parts together or in detaching them.

This invention relates exclusively to the construction and manner of connecting a pair of skate-rollers with their axle. The ordinary way of securing such rollers is by the passage through the holes centrally made in the wooden rollers of an axle-bolt having a head at one endand a slot in the other for the reception of a bent retaining-wire. This construction is obj ectionable, for the reasons that the oil used for lubricating is free to escape outside through the central hole in the roller, and soils the dress of the skater. The dress also catches against the projecting end of the axlebolt and its retaining-pin. Said projecting end and pin under one skate are liable to strike against the corresponding portions of the axle under the other skate of the pair'on the feet of the skater. The dirt is sure to accumulate around the axle and grind and wear away the bearing in the wheel, and enlarge the hole therein so rapidly that the axle and wheels play tod loosely on each other, and it is difficult to remove the retaining Wireor pin when the parts are to be separated to clean them.

To overcome these objections is the purpose of my present invention, which consists in a wheel having a metal box for the reception of a journal, which screws on a threaded end of the axle, and is locked thereto by a key when adjusted, a smooth metal face-plate flush with the outside of the wheel being employed to holdthejournal-box therein, and an inner faceplate to retain the journal within its box, by which construction oil is entirely or in a great measure prevented from escaping from the wheel. Y catch against. Dirt is precluded from entering the journal-box,- the rattling of the parts avoided, the friction reduced to' the minimum, and the wear readily compensated by the ad; justable journal.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

. In the said drawings, A represents a wooden roller, having a cylindrical hole, a, passing centrally throughl it, Fig. 13, and provided with an inner and an outer annular shoulder, b, the said hole being for the reception of a journalbox,B, Figs. 1, 5, and 6, having an inner annular flange, c, of considerable diameter let into the inner face ofthe wheel, and for a smooth plate, G, Figs. 1, 7, and 8, fitted in flush with the outside ofthe wheel, the outside of the No projections exist for the dress to journal-box screwing into the turned-down portion d ofthe interior of the outer faceplate,

vC, by which means they are both retained in their proper positions in the wheel.

e is a circular hole made through the outer face-plate, C, for the reception of a springactuated pin, f, located in a hole, g, in the contiguous portion of the wooden roller A, when the hole e in the plateis brought in line with the pin after the plate has been turned sufdciently to draw the j ournal-box B into the desired position in the wheel, the pin preventing IOO the revolution of the plate C and its unscrewing and separation from the journal-box. The journal-box is also prevented from turning accidentally and unscrewing from the outer faceplate, C, by headed pins Z1, which pass through the iange c ofthe journal-box B into holes t', made in theadjacent innersurface ofthe wheel.

D, Fig. 2, is the axle, each end of which has ascrew-thread, k, eut thcren,over which turns a sweat-threaded hollow journal, Z, Fig. 3, previded at its inner end with an annular flange, on, which tits into ashouidered recess, a, of the journal-box, Fig. 5. rIhe outer end ofthe axie is provided with a rectangular notch, p, and the annular wall of the corresponding end et' the journal is also provided with two notches, q, ofsimilar width, diametrically opposite each other, the notches in thejournal and axle being for the reception of a key, r, Fig. 4, for locking them together, when so adjusted as to bring` the inner side of the flange in ot' thejournal against the outer side et' an inner faceplate, E, and cause the latter to abut against the contiguous end of the bearing G of the axle on the under side ofthe skate, the inner faceplate, E, being provided with a number ot' slots, s, corresponding to those et' the headed pins l1, each slot having an enlarged portion, t, to admit el' the plate being fitted upon the flange m of the journal-box, after which said plate is turned apartial revolution by a short projection, a, till the plate passes under the heads ot' the pins h, and a notch, e, in the periphery et' the plate is brought in line with a spring-actuated pin, zr, located in a hole, x, in the inner surface of the wheel, and passing through ahole, y, in the fiange in ofthejournal box, whereby thcinner plate is prevented from turning and the wheel from being detached from its journal, the distance between the two inner tace-plates, E, corresponding to the distance between the ends of the axle-bearing G on the under side ofthe skate.

To lubricate the jou rnais ofthe axle, an oilpassage, s, is provided, said passage extending from the outside of the inner face-plate, E, through the tiange m of the journal-box B, through the latter to the journal Z, whereby the lubricant is conducted to the surfaces,

where the greatest friction occurs, the outer end of the journal-box being closed to preclude the escape of the same and soiling the dress of the skater.

To remove the parts, when the journals are to be adjusted to compensate for the slight wear resulting by continued use, or for other purposes, I employ a Spanner-wrench, II, (of

the form seen in Fig. 14,) having two projections, 16, the longer one of which enters the hole c in the outer plate, C, occupied bythe pin f, which is pressed in against the resistance of its spring, thus permitting the plate to be unscrewed from thejournal-box, the inner faceplate, E, being unlocked after pressing the spring-pin w out ofthe notch e.

The outer face-plate, C, may be provided with a central hole, and the journal-box Z be lengthened, so as to extend therein; but in such case the outer surfaces ot' both would be continuously smooth and flush with each other to avoid the existence ot' objectionable projections.

I claiml. An axle, D, having screwthreaded ends,

journals Z, capable of adjustment thereon, and

a means ot' locking them thereto, in combination with a pair et' rollers, A, having journalboxes B, and a means of securing them therein, constructed to operate substantially as and for the purposes described.

2. An axle, D, having its ends provided with screw-thrczuls k and notches p, in combination with notched journals Z, adjustable thereon, and keys r, for locking them thereto, as set forth.

3. A roller, A, having ajournal-box, B, and an outer face-plate, C, for retainingit/therein, an axle, D, having screw-threaded ends, a journal capable of adjustment thereon, and an inner faceplate, E, for locking the. roller upon the journal, as and for the purp0-c specified. \Vitness my hand this 31st day of January, 188i.

CIL/XS. F. MORSE.

In presence of- N. W. S'rnimxs, Exocn R. Mensa.
