THOMAS S. LEITOH, OF SEATTLE, WASHINGTON.

ROLLER-SKATE.

Be it known that I, THOMAS S. Lnrron, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and j useful Improvements in Roller-Skates, of which the following is a. specification, reference being had therein to the accompanying drawlng. U V

TlllS invention relates to an mprovement in roller skates, and has for its object, the

provision of peculiarly constructed means for strengthening a footplate.

Another ob ect of the invention-is the improvement of the construction of a brace extending longitudinally of a skate, which brace will prevent the foot-plate from bending or buckling, under strain, while the skate is in use.

With these and other obj ectsin view, the

:invention consists of certain novel constructions, combinations,1and arrangements of parts, as will be hereinafter fully described and claimed. 'f l 1 I i In the drawings: Figure 1 is a longitudinal, vertical, sectional view of a roller-skate constructed in accordance with thepresent invention. Fig. 2 is an inverted plan view of the structure depicted in Fig. 1. Fig. 3 is a perspective view of a brace constructed .in accordance with the presentv invention. Flg. 4 1s a vertical, sect onal view taken on line 4, 4, Fig.1. 1

Referring to the drawings byrefer'ence numerals, 1 designates, preferab1y',-a sheetmetal foot-plate, which is provided at its rear end with a vertical extension 2, provlded with apertures 3 for recelving ordinary heel-straps.

The hollow brace. 4. ,1. substantially ushaped intermediate its ends, see Fig. 4, and

at each end,-the sides of thebrace 4' are forced' together for producing I engaging, straight, vertical, parallel portions 5, 5. Near the center of the hollow or U-shaped brace 4, there are formed vertically-extending; lugs 6, 6, and near each end of the brace,

and uponthe parallelportions 5, 5,'"there are formed lugs 7,7. The lugs 7 at'each end of the brace constitute a single-lug, which extends through an aperture of the foot-plate 1, at 8. The central lugs 6 also extend through apertures near the center of the foot-plate. All the lugs 6 and 7 are upset after they have been positioned in their respective apertures of the foot-plate,'thereby.

forming heads upon the lugs or studs for preventing the brace from being detached or removed from the foot-plate, under ordinary conditions. Of course, it will be obvious that by filing ofi the head, the brace may be removed from the foot-plate, after the lugs have been upset. The closing of the sides of the brace together at its ends and spreading the integral body portion apart for forming "a hollow U-shaped structure, produces a very durable structure, as a great area of the under-face of the foot-plate is engaged by the brace which produces a broad bearing surface for the same, resting upon the brace,

which reinforces a comparatively large portion of the foot-plate, whereby the strain on the same is distributed upon the brace, thereby preventing a sheet-metal foot-plate from being bent or buckling or twisting, especially during the use of the same by an expert skater. At one end, and, preferably, near the front end of the brace, there is a substantially semi-circular cut-out portion or notch 8, while at the rear end, there is formed a notch or. cut-out portion 9, which notch or cut-out. portion. 9 is provided with an inclined face orwall 10 and a vertical, rear wall 11. It is to be'noted that these notches or cut-out portionsv 8" and 9 are formed in the engaging sides ofxthe brace, which engaging sldes constitute comparatively solid end-portions, greatly strengthening the entire structure.

Sheet metal truck brackets 12, are provided with substantially horizontal lugs 13,

iandtthese lugs 13 have rivets 14 extending therethrough, which rivets also extend through the foot-plate, thereby securing or attaching the truck -brackets to the same.

The truck-brackets are provided at their mary clamp-member 1 6, which is provided at its upper end with a right-angled extension 17 An auxiliary clamp-member 18 is provided at its upper end with a rightangled extension 19. Fixedly secured to the right-angled extension 19, is a short extension or shaft 20,wh1ch shaft extends through the r1ghtangled extension 1', and thereby secures the auxiliary member 18, at its upper end, to the primary member 16. A bolt 21 is threaded through the lower endof the primary member 16, and through the lower end or extension of the truck-bracket 12. A locking-nut 22 is threaded upon the bolt 21, between the primary and auxiliary clamp members 16 and 18, whereby the bolt 21 is securely fastened upon the truck, when the nut 22 is threaded tight against the under face of the primary member 16. It is to be noted that the lug or shaft 20 is mounted in bearing formed upon the extension 17 of the primary member 16.

Interposed between the two clamp- members 16 and 18, is a yielding member 23, preferably, a piece of rubber, which acts as a cushion; it will be obvious that any lateral strain upon the truck-brackets, or any sudden depression thereof will slightly depress the yielding blocks or members 23, which produces a cushion effect upon the axles 24. The axles 24 are, preferably, polygonal, and are provided with any ordinary type of ball bearing wheels 25. The axles 24 are, preferably, secured to the under face of the auxiliary members 18, by means of an axlebracket 26, which bracket is, preferably, provided with rivets extending through the same and the auxiliary clamp-member.

The primary clamp-members are provided with downwardly-extending side flanges 27, whereby lateral displacement of the rubber block or cushion 2-3 is prevented.

The toe-clamp comprises ordinary clampmembers 28, which are adjustably connected by means of a right and left threaded screw 29, which screw is provided at its center with a smooth portion 30, seated within the notch 8 of brace a. The brace at acts as a bridge for the screw-clamp 29, and as heretofore stated, owing to the peculiar construction and assembling of the brace with the other parts of the skate, a very durable and efficient structure is produced.

What I claim is:

1.
