(Cl. 280-1137) This invention relates to roller skates, the pri mary object of the invention being to provide a traction device attached to the skate in such a way that the traction device may be swung to a 2 metal material in such a way as to provide ?anges 15 along its longitudinal edges, the ?anges l5 being inclined inwardly toward each other, to position beyond the rollers of the skate, to permit Cr grip the traction pad 56, which may be in the form of a leather or rubber block. the person using the skate to walk over polished loors, and up or down steps, without danger oi slipping. The ends of the main plate l4 are extended upwardly at right angles, and provide ears H, which are formed with openings to receive the washers I8 and I9, which washers are mounted on the axle 'i, at opposite ends thereof, the wash ers contacting the ends of the axle housing 9. necessity of making alterations in the usual skate It is therefore obvious that when the rollers are structure, to mount the device. positioned and the nuts 20 at the ends of the axle With the foregoing and other objects in view which‘ will appear as the description proceeds, the 15 are tightened, the tubular hub sections will be tightened against the washers to secure the wash invention consists of certain novel details of con ers in their proper positions on the axles, and struction and combinations of parts hereinafter this tightening of the nut 29 will not in any way more fully described and pointed out in the eifect the free rotary movement of the rollers on claims, it being understood that changes may be their hubs. made in the construction and arrangement of 20 Spaced notches 2| and 22 are formed in the parts without departing from the spirit of the washer l8 mounted on each axle, th'e notches be invention as claimed. ing designed to receive the pivoted latch arm 23 Referring to the drawing: which is secured to the main plate M of the trac Figure l is a perspective view of a. skate con structed in accordance with the invention, the 25 tion pad housing. The pivoted latch arm is con structed of yieldable metal, so that the natural attaching device being shown as in its extended tendency of the latch member is to move into position. engagement with‘ the washer associated there Figure 2 is a bottom plan view thereof. with. A notch 24 is formed in the ear I‘! in which Figure 3 is a longitudinal sectional view taken the Washer 18 is positioned, so that the latch on line 3-3 of Fig. 2. 30 member may be moved into the notch 24 to per Figure 4 is an enlarged perspective view illus mit the latch arm 23 to clear the washer [8 when trating one of the rollers and traction device it is desired to rotate the traction pad housing to mounted on the axle thereof. An important object of the invention is to pro vide a device of this character which may be at tached to roller skates now in use, eliminating the Figure 5 is a perspective view of one of the traction devices. Figure 6 is a vertical sectional view through a roller of the skate. Referring to the drawing in detail, the body portion of the skate is indicated by the reference naracter 5 and includes front and rear brackets B which‘ support the axles ‘I on which the wheels 8 are mounted. Forming a part of each bracket 6, is an axle housing 9, the axle housings being of widths to space the wheels 8 on their axles. The rollers, forming a part of the skate, are provided with tubular sections 1B formed with annular flanges H at their ends, the ?anges ll acting to hold the roller sections l2 in place, the sections l2 being provided with the usual ball bearings l3. The traction device, forming the subject matter of the present invention, comprises a holder em bodying a metal plate constructed to provide a main plate l4 stamped out of a length of sheet move it to its active or inactive position. A laterally extended ?nger piece 25 is formed on the pivoted latch arm 23, and affords means whereby the latch arm may be moved from its position within a notch of the washer Hi to re~ lease the traction pad housing for pivotal move— ment. From the foregoing it will be seen that due to the construction shown and described, the trac tion pad housings may be moved to their active positions as shown by Fig. 1 of the drawing, where they extend beyond the rollers of the skate so that the person using the skate may walk on polished floors, or steps, without danger of slip ping. When it is desired to use the skate in skating, the traction pad housings may be swung to the positions shown by Fig. 3 of the drawing where they are out of the way, allowing free use of the rollers. What is claimed is: l. The combination with a roller skate in cluding an axle, an axle housing and rollers 2,405,000 3 mounted on the axle, said rollers including sta tionary hubs around which the rollers operate, of a traction device embodying a housing having openings, washers fitted within the openings and 4. The combination with a roller skate in cluding an axle, an axle housing and rollers mounted on the axle, of a traction device includ ‘ing removable washers secured to the ends of the axle housing, a traction pad housing mount ed for pivotal movement around the washers, being mounted on the axle, said traction device adapted to pivot around the washers, said wash means for securing one of the washers and ers being clamped between the ends of the axle traction pad housing together, whereby said housing and stationary hubs of the rollers, one traction pad housing is held in either its active of the washers having notches, a latch member or inactive position, and a traction pad mounted mounted on the traction device and adapted to in the traction pad housing. move into either- notch, securing the traction 5.
