ROLLER SKATE.

Application filed March 11, 1925. Serial No. 14,638.

This invention relates to improvements in skates and more particularly to roller skates of the two or three roller type; it being the principal object of the invention to provide skates of the above character wherein the rollers are supported through the intermediacy ofshock absorbing springs.

Another object is to provide skates having the rollers arranged in the central longitudinal line of the skate as distinguished from being arranged in pairs as is ordinary practice. V

A still further object resides in the provision of means whereby the skate may be adjusted to difi'erent lengths and secured at the different positions of adjustment.

Another object resides in the provision of. a three-roller skate wherein the central roller is mounted slightly below the line of the two end rollers in order that only two rollers of the skate will be in contact with the floor at a time.

Other objects reside in the details of construction and combinationof parts whereby the toe and heelsections are joined rigidly substantially and adjustably together.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein Figure l is a side view of a three-roller skate embodying the present invention.

Figure 2 is an under side plan view of the same. i

Figure 3 is a transverse section taken through a roller and its supporting bearings.

Figure 4 is an enlarged, transverse section taken on the line 4-4 in Figure 1.

Figure 5 is an enlarged, transverse sectional view showing the clamping means whereby the skate may be secured to the sole of a shoe. c

Figure 6 isa side view of a two-roller skate.

Referring more in detail to the several views of the drawings- 1 and 2, respectively, designate the heel and toe plates of the skate which are joined adjustably and held rigidly in functional relation by means of two overlapping ribs 3 and 4; the former of which is secured centrally beneath and longitudinally of the heel plate and is adapted to slide upon the rib 4 which is secured likewise to extend rearwardly from the toe plate. Each of these ribs 3 and 4, as is shown best in Figure 3, has a fiat central portion from which flanges are turned downwardly along opposite sides. Rivets 5 and 6 are extended respectively through these flanges and through parts that support the roller, presently described, to hold the ribs rigid. The former portion of rib 8 is adapted to move telescopically between the upper side of rib 4. and under face of the toe plate 2, and its flanges slide upon the flangesof the rib 1 and within the upturned edge portions 4 of the latter, as is shown best in Figure 4. Thecentral portions of the ribs 3 and t are provided with longitudinallydirected and registering slots 7 or provided with a series of registerable apertures and the heel plate with an opening 8 through which a set screw 9 is extended and which has a nut 9 adapted to be tightened to lock the parts at the different positions of adjustment that may be made.

Secured to the under sides of the heel and toe plates are roller mountings; those of the heel plate being for a single roller and coinprises two metal housings 10' and 10 secured by rivets 11 through outturned flanges 12 along their upper edges. These housings are disposed in spaced relation and a roller 13 is mounted between them on a transverse shaft 14, the ends of which extend through slots 15 in the housings and are mounted in blocks 16 that are adapted to move slid-- ably in upwardly and forwardly directed guideways 17 formed by the housings. Coiled springs 18 are contained in the housing guideways, and these bear against the upper ends of the blocks 16 to yieldably resist their upward movement and thereby absorb all shock and jar on the roller. The roller is rotatably mounted on the cross shaft through the intermediacy of a double set of ball bearings, as shown at 9-0, and is spaced to prevent rubbing contact with the housings by means of washers 21 at its opposite sides.

Secured to the under face of the toe plate are housings 22 and 22" for mounting two rollers 24 and 25 in a line centrally of the plate and in line with the heel plate roller. The central roller 24 is disposed somewhat below the line of the two end rollers in order that only two rollers will contact with the floor at the same time. These rollers are 'fixed to blocks operating in gruideways 31 and the guideways 29 and 31, at opposite sides at: the rollers. are. inclined upwardly and toward each other as shown in Figure 1.

Secured to the rear edge of the heel plate 1 is a retainingflange :t'or holdingthe skate properly on the heel of the user and secured to the toe plate are clalnps 36 and 37 for engaging opposite edges out the sole of the shoe of the user. These clainps are connect ed by and may be adjusted by the rotation of a right and left hand screw 38 as is provided on skates now in use.

In Figure 6. as shown a two roller skate diilers from the one just described in that the toe plate has only one roller attached thereto. this skate being; more suitable for childrens use. 7

\Vith a skate of the above character, it is possible to adjust it to suitable length by loosening the nut 9 and adjusting the ribs and l upon each other. The adjustment may be retained then by tightening the nut.

It is also apparent that by the use of the spring mountings for the rollers, all shock or jar is absorbed and an easy, cushioning effect is provided.

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

1. In a skate ot' the class described, a heel plate, a toe plate, rollers mounted on said plates. a rib fixed to the heel plate and extended forwardly thereof having a slot therein and having downturned flanges along its side edges, a rib fixed rigidly to the toe plate to extend rearwardly therefrom and adapted to be OVGl'ltIPPGCl by the first named rib and having a slot therein and having downturned flanges along its side edges with upturned edges 'lorn'iing channels whereir the flanges of the first named rib are adapted to fit and a locking bolt extended through said rib slots to lock the same together at different positions of a dj ustinent.

2. In a skate. ot' the'elass described comprising relatively adjustable heel and toe plates, a series of supporting rollers inounted in alineinent centrally beneath said plates comprisinga forward roller, a rearward roller and a central roller; the latter being; mounted slightly below the line of the two end rollers. all of said rollers being provided with yieldable n'iounting hearings which permit the rollers to aline with each other when sufi'ieient weight is placed on the skate.

Signed at Seattle, King County, Washington, this 11th day of February T924.
