UNITED STATES PATENT OFFICE ROLLER SKATE WHEEL MOUNTING Paul J. Owsen and Peter Owsen, Dearborn, Mich.
Original application April 25, 1950, Serial No. 157,928. Divided and this application July 28, 1951, Serial No. 239,101
This application constitutes a division of our application Serial No. 157,928, iiled April 25, 1950.
The present invention relates to a roller skate Wheel mounting adapted for use on a roller skate used for skating on hard surfaces, such as floors, pavements and the like.
It is an object of the present invention to provide a skate of this class having the traction members so mounted that jars and shocks received thereby are not transmitted to the skater.
Another object of the invention is the provision of a skate of this class of a mounting for the traction members so arranged and constructed that a iiexing of the main body of the skate relative to the traction members and a tilting of the axes of the traction members relative to the longitudinal center of the main body may be easily and quickly effected thus facilitating the steering of the skate.
Another object of the invention is the provision of a skate of this class which may be economically manufactured, which may be durable, light and highly eicient in use.
Other objects will appear hereinafter.
It is recognized that various inodiications and changes may be made in the detail of structurev illustrated and it is intended that the presentVV disclosure shall be considered but the preferred embodiment.

' Fig. '7 is a perspective View of a support used in the invention.
A rear heelengaging plate 4t is provided with an upwardlyextending flange if? at its rear end.`
Secured to' this :flange 4"! are the straps 8 which are adapted to be fastened around the foot of the user in the'usual manner. Secured to the bottom face of theplate 4S and projecting downwardly therefrom is the bar 48a having the side Walls 49 and 56 eachprovided With the inwardly turned vllange :il which are` spaced apart.""This bar 48a slidably engages as a snug rit inthe mern' ber 22 and may be secured in xed relation thereto at various positions of longitudinal movement by means of the bolt 52 and wing nut This bolt 52 is projected through an opening t formed in the member 22 and engaging at itsv head 55A The wing nut 53 bears against Formed on the upper face' with a Washer 56. the lock Washer 31. of the bar 48a are graduations 58 so as to indicate the various lengths of adjustment of thev plates 2l and 4S to accommodate shoes oi various sizes.
the Vmember 22 is a retainer comprising the plate 5S having an opening 6i] formed substantially' therein. The ends of the plate E@ are providedfor both. f Y
As shown on the drawings there are four traction Awheels and at each of these wheels there is mounted a spring embodying the horizontally disposed portion 55 having the angularly upwardly turned end Gli projecting through one of the openings E? formed in the plate 59. Positioned beneath the plate 59 is a clamping plate S8 having an upwardly directed flange 69 at each end, each ilange being provided with a recess 'le in'which the member i engages. This plate 58 is also provided with an opening lland a bolt'l2 extending through the `opening 1| and through the opening E@ and is provided with a nut upperface of a resilient yielding block 71S preferably formed-from rubber.rvr This block lil-is pro- Mounted on the bottom of the forward end of Y The mounting andrstruc-v ture of the wheels at both ends ofthe skate are? the saine so that a description of one will suice 'I3 whereby the plate may serve' to clamp the portion S5 in engagement Withv the plate 59 and prevent disengagement of the' vided at its lower end with a recess 80 in which engages an arcuate rib or bulge 8| extending upwardly from the metal plate 82. This arcuate bulge or rib 8| seals over a spacing tube 83 through which extends a bolt 84 having a nut 85 at one end.
By mounting the traction members in this manner it is believed obvious that an easy steering of the skate becomes possible as the traction members may tilt vertically relative to the shoe supporting plate and also transversely.
In the form shown in Fig. instead4 of providing a separate plate such as the plate 48 we provide a plate |20 which is formed integral with the bar |48 which corresponds to the member 48a. of the form shown in Fig. 1. This member |48 telescopes in the member |2| which corresponds to the member 2| shown in Fig. 2. Projecting downwardly from the member |20 at opposite sides is a side flange |49 which serves as a reinforcement.
The bottom |5| of the member |2| has the downwardly directed portion |52 terminating in the upwardly inclined portion |53 which serves as a support and which is provided with an opening |54 through which is projected the head |55 formed in the plug |56 which corresponds to the plug 19 shown in Fig. 2. A cap |51 is fitted over the lower end of the plug |56 and has the inwardly pressed portion |58 which is arcuate in cross section to receive the spacer |59 which corresponds to the spacer 83 shown in Fig 3. A spring embodying the portions |14 and |55 which correspond to the parts 141 and 85 shown in Fig. 2 is provided with the coil |l5 corresponding to the coil shown in Fig. 2 and Fig. 3. The upwardly turnedA end |88 corresponding to the part B8 shown in Fig. 2 is projected through an opening |80 formed in the plate A bolt |62 is projected through this plate |0| and |54 so that the spring' through a clamping plate mounting is thus clamped securely on the plate |6I. The primary difference between this type of mounting the front wheels of the skate from that shown in Fig. 2 is that the member |55 is inclined to the vertical so that thrusts delivered against the traction wheels are transmitted more longitudinally of the member |58 than they are of the member 19.
Similarly the rear wheels are mounted so that the block |18 of rubber or other yieldablermaterial is also at an incline and provided at its bottom with a cap |19 having the arcuate recess |80 formed therein to receive the spacer |8|. To accomplish this we provide a boxlike supporting structure having the rear wall |82, the inclined forward wall |83 and the side walls |84 and |85 extending outwardly from each of which is a flange |00 which is spot welded or otherwise secured to the under surface of the member 20. Openings |81 are formed in the bottom |80 of this structure through which projects the upwardly turned end |39v of the spring arm |99. A downwardly inclined portion |9| at the forward end of the plate |80 is provided withthe opening |92 through which is projected the head |93 of the block |18. A bolt |94 is projected through the plate |88 and through the clamping plate |95 so that the spring arm |90 may be securely clamped to the plate |88.
Themodication is made primarily to locate the member |18 in the inclined position so thaty the thrusts delivered thereto will be generally longitudinally thereof. Y
We have eliminated in the form shown in Fig. 5
the wing nut shown in Fig. 2 and instead of this construction for'retaining the members 48 and 2| in their various adjusted positions we mounted within the member 48 the washer |95 through which is projected the bolt |91 which also extends through the members |2| and |4| and through the washer |98. The lever |99 is provided with a .head through which thebolt |91 projects, this head 20| being of a flat disc-like construction and provided with the downwardly projecting ribs or corrugations 202 which are adapted to co-act with the corrugated spring washer 203 held in position by the nut 204. When the lever |99 is rocked so that the corrugations 292 will mesh in the corrugations 283 the members |2| and |48 may be moved longitudinally of each other. When ther lever |99 is swung to the position shown in Fig. 6 so that the corrugations 202 ride out of registration with the corrugations or recesses 203 a clamping effect will be obtained so that the members |2| and |48 will remain in fixed position. The tension of the mem-bers .-5 operating 20| and the spring washer may be adjusted by threading or unthreading the nut 284. By this method of securing the members |2| and |48 in fixed position we have provided a simple and effective means whereby the clamping relation between these parts |2| and |48 may be easily effected and easily and quickly released without resorting to the use of a screw such as shown in Fig. 2.
Experience has shown that with a roller skate constructed in the manner herein described in addition to obtaining a substantially noiseless roller skate on which the user will be relieved materially of the jars and shocks customarily encountered in roller skating, the structure is one which is very durable, may be economicaily manufactured and which may be easily and quickly adjusted to flt various sized shoes and easily and quickly fastened on the shoe and removed therefrom.
