Application May 27, 1939, Serial No. 276,180
This invention relates to roller skates, more particularly to roller skates adapted for use on a roller rink. The principal object of this invention is to provide new and improved roller skates.
In the drawing accompanying this specification, and forming a part of this application, there is shown, for purposes of illustration, one form which the invention may assume, and in this drawing:
Figure 1 is a side elevational view of a roller skate illustrating an embodiment of the invention,
Figure 2 is a bottom plan view of the roller skate shown in Figure 1,
Figure 3 is an enlarged fragmentary sectional view along the longitudinal center of the skate, and
Figure 4 is a more or less diagrammatic view showing a relation of parts of the skate under certain conditions.
The embodiment herein shown to illustrate I the invention comprises plate means Ill, which may be formed similar to the plate means of a roller skate of usual construction. The plate means ID, at its rear end, may have the usual heel cup ll, formed with slots to receive a fastening strap l2, while at its forward end, the plate means may have the usual clamping structure l3. 7
Rigidly secured to the plate means Ill, and extending from the under surface of the plate means, are members I4, spaced apart longitudinally with respect to the plate means It], each member forming connection providing means for receiving corresponding parts of a roller carrying means I5. In the embodiment shown, each member comprises spaced blocks l6 and I 1, each block providing a socket for receiving a part of the respective roller carrying means IS. The block I 6 is in the form of an inverted cup, having an aperture l8 formed in its closed end, whereas the block 11 is formed with a screw threaded aperture l9 extending therethrough. The portion l1 also has a screw-threaded aperture 20 disposed at an angle to the aperture [9, the axis of the aperture 20 being generally parallel to the plate means In.
- The spaced blocks l6 and I1 are formed with apertured ears 2| for receiving rivets 22,. the rivets also passing through the plate means II], for the purpose of rigidly holding the blocks assembled with the plate means. Means are provided to brace the construction of the roller skate adjacent each of the membersv l4, and
as here shown, this means comprising a strut 23, formed integral with and extending between the blocks ([6 and |1, but being preferably spaced from the plate means In and inclining upward from the block 11 to the block l6- The roller carrying means 15 comprises a housing or axle carrier 24, for receiving an axle 25. Extending from. the housing 24 are arm means 26 and 21, these arm means diverging ,with respect to each other from the housing 24 in a direction toward the plate means 10. The arm 21 is inclined a greater amount with respect to the vertical than is the arm 26, as clearly shown in Figure 3. The ends of the arms 26 and 21 of each roller carrying means l5 are secured to a respective member l4, suitable means being interposed to minimizethe transmission of shock from the 'roller carrying means 15 to the plate means I, when the roller skate is in use, while at the same time permitting movement of the roller carrying means I5 relative to the plate means 10.
As here shown, the arm means 26 comprises a portion 28 integral with the housing 24, the end 29 of this portion being of a cross-sectional size somewhat smaller than the area of the cup or socket formed by the block IS. A shoulder 30 is formed by the reduced end 29, this shoulder being spaced inwardly from the extremity of the end, and resilient means 3| is carried by the end 26. The resilient means 3|, as here shown, comprises a tubular rubber buffer fitting over the end '29, and being of a cross-sectional size to snugly fit the cup or socket formed by the block l6. The cross-sectional sizes of the end 29 and the aperture I8 in the cup or socket formed by the block l6 are so proportioned that when the rubber bufl'er' is compressed, the extremity of the end 29 may freely extend into the aperture I 8.
The arm means 21 comprises an abutment 32 integrally extending from the housing 24, and being apertured as at 33.- The abutment 32 is provided with a seat 34, in which is positioned resilient means, such as the rubber buffer 35 herein shown. The rubber bufier 35 is provided with an aperture 36, through which freely extends the shank of a screw-threaded stud 31, the aperture 33 in the abutment 32 being enlarged with respect to the cross-sectional size of the stud 31, as shown in Figure 3. The head 38 of the stud 31 overlies the surface of the abutment opposite the seat 34, a washer 39 being preferably interposed between the head 38 and the adjacent surface of the abutment 32.
threaded extremity of the stud 81 is screwthreadedly received within the socket or aperture i9 formed in the block H. A sheet-metal cup metal cup 40 to the rubber buifer 35, adjust-' ment of the-nut 4i providing for the desired compression of the rubber buffer 35.
As willbe, clearly seen in Figures 1 and 2,
the members M are similar, but oppositely disposed. so that the apertures 20 in the facing blocks I! are in aligned relation. Means are provided to brace the skate structure, and particularly that portion of the plate means i which lies between the members M. The brace means, as here shown, comprises a rod 42 underlying and preferably spaced from the bottom surface of the plate means ID, the rod 42 having screw-threaded extremities respectively received within a screw-threaded aperture 20. Thus, the plate means I0 is held against bending or buckling action under any circumstances. As best seen in Figure 1, the rod 42, in effect, forms a continuation of the strut 23, and in this manner forms a truss construction effectively reenforcin the entire roller skate construction.
The invention herein disclosed provides a construction wherein each wheel carrying means I5 is assembled with the plate means III at a plurality of points, suitable means being provided at-these points to prevent shock from being transmitted from the wheel carrying means l5 to the plate means I0. Also, the construction is such that when pressure is applied to one side or the other of the plate means It}, the plate means will tilt downwardly at that side where pres-' sure is applied, as shownin Figure 4. This tilting movement causes a combined compression and twisting of the rubber buffers 3i and 35, causing each of the wheel carrying means l5 to twist a proportional amount, the wheel carry.- ing means moving in complementaryrelation, so that the user of the roller skate'may steer the skate in any desired direction by applying a greater pressure on one or the other side of the plate means I 0. When this greater pressure removed, the resiliency of the rubberbuffers will bring the, wheels to straight forward position. Inasmuch as the nut 4| adjusts the compression 1 a of the butter 35, compression as wellas torsion oi the buifer 35 is controlled, therebycontrollingm the shock absorbing qualities as well as the steer ing qualities of the skate construction.
v Itwill be apparent to those skilled in the art; that we have accomplished at least the principal object of our invention, and it, also will be apparent to those skilled in the art that the embodiment herein described may be variouslyv changed and modified, without departing from limited thereto.
