This invention relates to skates of the wheel or:

roller type, and has for the primary object the provision of a device of this character wherein a pair of wheels will be employed on each skate and arranged in tandem formation, that is a rear` wheel and a front wheel, and each of a construc` tion to reduce friction to a minimum, so that exceptional high speeds may be obtained by the skater as Well as permitting the skater to have a greater amount of grace in skating. l

Another object of this invention is an improved construction of wheel fork that may be employed either for the front or rear wheel and readily and efficiently secured to the skate platform and which will provide fo-r a balanced distribution of the skaters weight on the wheels.

A further object of this invention is the provision of a platform construction easily adjustable as to length to permit the skate to be adjusted for different size shoes.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating a skate constructed in accordance with my invention.

Figure 2 is a top plan view illustrating the same.

Figure 3 is a sectional View taken on the line 3-3 of Figure 1.

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 1.

Figure 5 is a side elevation illustrating one of the Wheels.

Referring in detail to the drawings, the numeral 5 indicates a platform including a heel portion 6 and. a sole portion 1. The general outline of these portions is in accordance with a heel and sole of a shoe and the heel portion 6 is provided with an extension 8. Also the sole portion l has an extension 9 and the sole portion adjacent to Where the extension 9 forms thereon is provided with a slot I0 to permit the extension 8 of the heel portion to extend therethrough. The extensions 8 and 9 have overlapping relation and the extension 8 is offset to extend through the slot I0 so as to bring the free end portions of the extensions to underlie the heel and sole portions of the platform, providing a construction which will permit the sections of the platform to be adplatform may be adapted to different size shoes.

Feed nuts II are mounted on the under face of the sections of the platform and one of said feed nuts has left hand screw threads While the other feed nut has right hand screw threads to match the right and left hand screw threads of an adjusting rod I2 provided between its ends or screw threaded portions with wrench-engaging faces I3. This construction permits the sections of the platform to be readily moved toward and from each other and the feed nuts have cut-away portions to form attaching shanks I4 and slot-like seats I5 therebetween through which the extensions 8 and 9 slide for maintaining said extensions in close sliding relation with the sections of the platform. The attaching shanks I4 extend through slots provided in the sections of the platform and are headed or riveted, as shown at I5. The sections of the platform upon their under faces are further provided with brackets or guides I6 in which the extensions 8 and 9 are slidable mounted.

The heel section 6 of the platform has riveted or otherwise secured thereon an arcuately curved heel plate Il to which is connected an ankle strap I8. The sole portion 'l adjacent its toe end is provided with transversely arranged slots I9 through which headed Shanks 20 of feed nuts 2| extend. The feed nuts are provided with right and left hand screw threads to match the right and left hand screw threads of an adjusting rod 22. The headed shanks 20 are employed for slidably securing a toe clamp 23 on the platform and which includes companion sections adaptable on the platform toward and from each other to permit the toe clamp to be adjusted to accommodate the toe portions of shoes of different sizes.

It is to be understood that the toe clamp 23 is so shaped as to receive therein the toe of a shoe providing the front mounting of the platform on a shoe.

Secured to the heel and sole sections of the platform are rear and front wheel forms 25 and 26 both of identical construction and either is mountable on the sections of the platform consequently eliminating the necessity of manufacturing forks of different construction from -each other for the heel and sole sections of the platform.

Each fork consists of plate-like portions 2l and each tapering toward one end with an arcuate curvature and provided in its smallest end portion with an axle opening 28. The major portions of justed toward and from each other so that the the plate-like portions 2l are of double wall construction with one wall bulged, as clearly shown in the drawings, presenting to the fork a streamline eifect and providing a rigid construction. Formed on the upper edges of the'walls are attaching shanks 29 which pass through slots provided in the sections of the platform and are riveted or headed, as shown at 3U. Y

Carried by theforks are wheels 3| each consisting of a hub 32 having reduced endY portions 33'fitted snugly in the axle openings 28 of the fork. The hub 32 is provided with a threaded bore in which are threaded stud bolts 34 acting to compress lock washers 35 against the fork and I Y slots therein, some of the slots of each group being also acting to retain the reduced end 33 of the hub in the axle openings. The wheel 3| further includes a rim 33 on which is mounted a cushion tire 31 and interposed between the rim and the hub is an anti-friction bearing`38 `so'that the rim can rotatewith a minimum amount of friction on the hub.V Side cover plates 39 are carried by the rim and, 'extend to the hub and free to rotate relative thereto. The plates 39 act to exclude dirt and foreign matter from the anti-friction bearings. cating opening normallyjclosed by a cap 40 so that the anti-friction bearings can be easily 1ubricated whenever necessary. I

mit a skater to obtain high speed and grace in skating and may be successfully used on various skating surfaces with a minimum amount of vibration and noise.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.

Having thus-described my invention, what I claim is:

i In a skate, a platform having four groups of arranged in an arcuate row and the other slots of the group being arranged in a straight longitudinallyextending row, a pair of front wheel carrying'members separate from each other, a

One of the plates 39 has a lubri- Y Skates constructed in accordance with the foregoing description andv as shown in the accompanying drawings will be extremely durable, eco-' nomical to manufacture and repair and will perpair of rear wheel carrying members separate from each other, each member having its upper portion formed of two walls, one wall being 'straight and theot'her wall being of arcuate shape,

the upperend of each wall having upwardly extending tongues thereon, the tongues of the `straight Wall fittingV in the slots arranged in a line and the tongues of the 'arcuate wall fitting in the arcuate row of slots, Ythe tongues being rivetedy to the platform and wheels rotatably arranged between the wheel carrying members of each pair.

Y THEODORE R. RONISH.
