ROLLER-SKATE.

. Specification of Letters Patent.

Patented July as, 1908.

' Application filed. February 13, 1907. Serial No. 357,187.

To all whom it may. concern:

Be it known that 1, JOHN HoHENADEL, a citizen of the United States of America, residing in the city and countyof Philadel .phia, in the State of Pennsylvania, have invented a certain new and useful Im rovement in Roller-Skates,of which the ollowing is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My present invention relates-to roller skates and" has for itsiobj'ect the provision of roller .skates with-braking devices applied to the skates in such'a'ma'nner as not to interfere with their ordinary use, while at the same 'timethe braking I devices may readily be brought into [operation whenever necessary or desirable] H A further object of my inventionis the provision on a rollerskate of abraking device which in addition toits braking func tion may also serve as a maneuvering device, assisting the skaterin controlling the char acter of the movementsexecuted by him- In carrying out my invention, I mount on the skate body, in addition to the ordinary rollers, an extra roller journaled on ashaft. extending in a substantially transverse dimotion to the axis of the rotation. of the ordinary rollers. Preferably I locate the extra roller beneathorclosely adjacent the toe end of the skate body with its sup orting shaft extending parallel to the genera direction of the skate body and so that the extra roller clears the floor by a substantial amount when all of the ordinary rollers bear on the floor, but so that the extra roller may be brought into contact with the floor when the skate is tilted so that all its ordinary rollers, or at least the rear rollers, are above the floor.

The various features of novelty which characterize my invention are pointed: out with particularity in the claims annexed to and forming a .part of this specification. For a better understanding of my invention, however, reference may be .had to the accompanying drawings and descri tive matter in which I have illustrated an 1 described one of the forms in which my invention may be embodied.

Of the drawings, Figure 1 is a side elevation of a roller skate having my invention applied to it. Fig. 2 is an inverted plan view of the skate shownin Fig. 1. 'Fig. 3 is a front elevation of the skate shown in Fig.

1 andFig. 4 is a sectional elevation of the extra roller taken on the line 44 of Fig. 2.

In the'form of my invention shown in the drawings, Arepresents the skate body which maybe of'any usual form and is provided with the usual front rollers B and rear rollers C and withsuitable devices for securing the skate in place such as the hook D and clamp E. i

. Against the under surface of the toe end of the skatebody A is secured a bracket F as by rivets F passingthrough flange portions F 2 of the bracket. bracket extends downwardly and supports at its lower end a stud or shaft G which forms a'bearing for the extra roller H. A brace F arranged as shown, serves to stiffen the body of the bracket. Preferably the extra roller H is substantially spherical as.

shown and has its outer portion formed of resilientand yielding material. shown, the body of the roller H is formed of rubber and has in it a bushing or sleeve H of suitable material, as metal or wood, which surrounds the shaft G. The roller H is supported at its rear by a washer H bearing against a boss or shoulder F surrounding the shaft Gand spacing the roll away from the body of the bracket F. The front end of the bushing H is enlarged at H and. is received in a recess Hhformed in the roller H. The roll is secured in. place in any suitable manner, as by an enlargement of the outer end of the shaft G formed by a short headed bolt I tap ed into the end of the shaft G, the head of t e bolt bearing against the enlarged end of the bushing H and being entirely re- As shown, the body of the In the form .ceived in the recess H formed in the outer 4 .of'the 'extra roller and hence the bolt cannot be brought into engagement with the floor.

With skates of the character just described the skater may arrest the movement of either. foot at will by simply tilting the skate until the rollH engages the floor with the desired pressure and this without necessarily lifting allweight off the front pair of rollers. The extra roller may be brought into play as a maneuvering device when executing certain movements not otherwise readily possible by moving the skate laterally while the extra roller bears on the floor. The character of the movement thus produced can, of course, be varied largely by varying the proportion of the weights put upon the front rollers and the extra roller and the position and amount of movement given to the skate body.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is,

1. In a roller skate, the combination with the skate body and the usual supporting rollers, of another roller pivotally supported by the skate body at the toe end of the latter to turn about an axis extending in a direction generally transverse to the axis of rotation of said supporting rollers, said other roller being so located that it is normally above the floor, but may be brought into engagement therewith at the will of the skater.

2. In a roller skate, the combination with the skate body and the usual supporting rollers, of a roller closely adjacent to the toe end of the skate body and a supporting shaft for the roller which extends substantially arallel to the general direction of the skate body and is so located relatively to the skate body and the usual rollers that the roller supported on it is normally held above the floor level, but may be brought into engagement therewith.

3. In a roller skate, the combination with the skate body and the usual supporting rollers, of a bracket secured to the skate body at its toe end, and a substantially spherical roller pivotally supported by said bracket to turn relatively thereto about an axis extending substantially parallel to the general direction of the skate body.

4. In a roller skate, the combination with the skate body and the usual supporting rollers, of a bracket secured to the skate body at its toe end, and a substantially spherical rollerpivotally supported by said bracket to turn relatively thereto about an axis extend.- ing substantially parallel to the general direction of the skate body, the outer portion of said spherical roller being formed of resilient material.

5. In a roller skate, the combination with the skate body A and the usual supporting rollers B and C, of the bracket F secured to the skate body A at its toe end the shaft G- carried by the bracket F and extending substantially parallel to the general direction of the skate body and having the enlarged outer end and the roller II of resilient material journaled on the shaft and having the recess P H receiving the enlarged outer end of the shaft.
