SPECIFICATION forming part of Letters Patent No. 243,323, dated June 21, 1881.
' Application filed May 6, 1881. (N model.)
To all whom it may concern a roller shafts.
Be it known that 1, WILLIAM A. SUTToN, of New York, in the county and State of New York, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification.
The object of this invention is to furnish a cheap yet strong and effective roller-skate for boys and girls, which has the advantage that it is composed of very few pieces, which can be assembled quickly, so as to reduce thereby the expense of the skate.
The invention consists of a roller-skate the sole -plate of which is provided at the under side with a longitudinal central rib, from the ends of which extend in downward direction central and side lugs for the support for the The soleplate has central recesses and the central rib flanged recesses below the same for the passage of the straps. The hind part of the sole-plate is provided with a heel-rest, cast in one piece therewith, and the side lugs with exterior central ribs, which serve as stopsfor the lockin g-keys of the rollershafts, so as to prevent the turning of the same with the rollers.
In the accompanyingdrawings, Figure 1 represents a side elevation; Fig. 2, a bottom view; and Fig. 3, avertical'transverse section of my improved roller-skate on line .2." m, Fig. 1.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents the sole-plate of my improved roller-skate, which is cast in one piece with downwardly-extending side lugs, a, near the front and rear ends of the sole-plate, which lugs carry the rollershafts B. At the under side of the sole-plate A is cast a longitudinal central rib, b, from the ends of which extend in. downward direction and in line with the side lugs, a, intermediate lugs, a, through which the shafts of the rollers pass, they serving. to separate the rollers at the front and hind part of the skate from each other. The shaft B is provided at one side with an enlarged head and at the other side with a diametrical hole, through which a springkey, (1, orotherfastening for retaining the shaft, is passed. The outer side lugs, a, are provided with'raised center ribs or other equivalent stop devices, a for the purpose of arresting the spring-keys d, and preventing thereby the roller-shafts B from turning with the rollers.
At the rear end of the sole-plate A is arranged an inclined heel-support, e, of segmental shape, which is cast, like the bottom rib and sidelugs, in one piece with the sole-plate, and which extends along the rear edge of the soleplate from one side lug to the other.
The straps are applied to the sole-plate by providing the same with central recesses, f, one in front of the hind rollers and the other somewhat back of the front rollers, and casting the longitudinal bottom rib with depressed side flanges, f, between which and the soleplate are formed transverse guide-slots for the straps, as shown clearly in Figs. 1 and 3.
As the sole-plate is cast in one piece with the rollersupporting lugs and the strap-holding devices, all that is necessary to complete the skate is to apply the rollers, roller-shafts, spring-keys, and straps thereto, the Whole forming a roller-skate of cheap and simple construction, yet of considerable durability and strength.
Having thus described my invention, I claim as new and desire to secure byLetters Patent 1. In a roller-skate, the combination of a sole-plate, having side lugs and intermediate lugs cast in one piece therewith, with front and rear rollers, and transverse roller-shafts secured to the side lugs, substantially as and for the purpose set forth.
2. In a roller-skate, a sole-plate having roller-supporting side and center lugs cast in one piece therewith, substantially as described.
3. In a roller-skate, a sole-plate cast in one piece with downwardly-extending side and central lugs, and with a longitudinal bottom rib that connects the center lugs, substantially as set forth.
4. In a roller skate, a sole-plate having a longitudinal bottom rib at the under side, central recesses, and transverse slots formed below the sole-plate by depressed sidewise-extending flanges of the bottom rib, substantially as set forth.
5. In a roller-skate, a cast-metal sole-plate having side and central lugs, strengthening bottom rib, and a segmental heel-plate which extends along the rear edge of the sole-plate as to prevent the turning of the shafts with from one side lug to the other, substantially as the rollers, substantially as set forth. set forth. In testimony that I claim the foregoing as 6. In a roller-skate, the combination of the my invention I have signed my name, in pres- 5 sole-plate having side and central roller-supence of two witnesses, this 14th day of April, 15
