1 WHEEL.

Patented May 22,1917.

Application filed September 19, 1916. Serial No. 120,915.

To all whom it may concern.'

Be it known that I, JOHN N. POWERS, a citizen of the United States, residing at lVashington, District of Columbia, have invented certain new and useful Improvements in Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in wheels and particularly to wheels for use on railway cars of all kinds where it is desired to materially' reduce the noise incident to the operation of the wheel in the progress of the car over the track.

To this end myrinvention contemplates the production 'of a wheel embodying a rim member and a core member and a layer of non-resonant material interposed between said member, the core member being so shaped as to'produce a substantially perfect balance of the wheel during its rotation and said members interlocking in such manner that the core member is held against outward displacement by the rim member, while tendency of the core member to displace inwardly is transmitted through the axle and counteracted by the inability of the core member of the opposite wheel to displace outwardly.

My invention further contemplates the production of a wheel of the type named wherein the use of boltsl in constructing the wheel is entirely eliminated and in addi` tion my invention also contemplates providing a novel form, and mounting of face or side plates which fully protect the interior portions of the wheel and are so constructed that they can be applied and will remain in assembled position without the use of bolts.

I will describe the invention in the best form known to me at present but it will be obvious that various changes in the detailsof construction and in the arrangements of parts can be resorted to with the exercise of only ordinary mechanical skill. In the drawings chosen to illustrate my invention, the scope whereof is set forth v in the claims- Figure 1 is a view in elevation of my improved wheel looking at the outer side thereof and with the face plate removed;

Fig. 2, a vertical section of the wheel with the face plates in the form they would possess before being forced into proper shape under pressure;

Fig. 3, a view similar to Fi 2 with the face plates pressed into final s ape;

Fig. 4, a perspective view of the core member of the wheel, and Y Fig. 5, a view showing a pair of wheels mounted on an axle', the wheels being shown -in section land resting upon respective rails of a railway track. 4 L

Referring to the drawings A indicates the rim member of the wheel and includes an inner section 10 and a tire section 11 which is shrunk upon the section 10 and constitutes in y conjunction with the latter substantially one piece. My improved wheel further embodies a corelmember B having a central passage 12 therethrough which is adapted to receive the spindle of.. an axle as is well known, such axle beingindicated at 13 1n Fig. 5. The core member B embodies a circular section 14 having its periphery concentric-with the axis of the opening 12, and

said section being provided with .a lateral e extension 15 havingk opposite recesses 16 adapted to receive inwardly extending-'lugs v17 on the section 10 of the\rim,member,A.

These lugs 17` abut the outer face of the circular section 14 of the core and serve as a means of preventing outward displacement of the core relatively to the rim member. Theperipheral surface of the circular section 14 and the corresponding surface of the extension 15 arecovered with a layer of suitable non-resonant material 18, which material, when the parts of the wheel are assembled is interposed between the inner periphery of the rim member A and the core B.

The rim member A has its inner periphery provided with continuous grooves 19 and 20,

v while the core member is provided with continuous grooves 21 and 22. The grooves 19 and 21 are adapted to receive the edge portions of a face plate 23 while the grooves 20 and 22 are adapted to receivethe edge portions of a face plate 24. These plates 23 and 24 when rst applied have annular bulges 26. When the plates are positioned as shown in Fig. 2 the bulges 26 are subjected to pressure and flattened out so that the face plates assume the shape shown in Fig. 3 and in this operation the edge portions of the plate 23 will enter the grooves 19 and 21 while the edge portions of the plate 24 will CIO enter the grooves 2O and 22 and thus complete the assembling of the wheel.

By referring to Fig. 5 it will be obvious that if the core member of the wheel on the right handside tends to displace outwardly it will be arrested by the lugs 17 of the rim member A while the latter'is held against outward movement by engagement of the usual wheel flange with the rail. Should the core of th-e wheel on the rightV hand side in F ig. 5 tend to displace inwardly such tendency will be transmitted through the axle 13 to the core member of the wheel on the left hand side of Fig. 5 but as this last named core member is held against outward dis-V placement it counteracts thetendency of the core member on the right hand side to displace inwardly. j

F rom the foregoing it will be noted that my improved wheel pr-esents little or no opportunity for the transmission of sound vibration from the'rim member to the core member while the face plates are subjected to substantially no strain and simply perform the function of forcing and holding the non-resonant material in proper position.

Furthermore my improved construction resists wear and tear on the wheel itself and upon the road bed and rails and in addition prolongs the life ofthe rolling stock in which the wheels are employed.

lVhat is claimed l. A wheel for preventing the transmis` sion of sound vibrations embodying a rim member, a core including a circular portion concentric with the rim member and having a diameter equal to the maximum diameter of the core, lugs on the rim member inter- Coyies of thiix patent may be obtained for ve, cents each, by addressing the Washington, D. C.

resonant material interposed between the r Vrim member and core.

3. A Wheel for preventing the `transmission of sound vibrations embodying a lrim member, a 'core' having a circular portion concentrlc'vvlth thernn member; an eXten- 5 sion on the outer face of the circular portion having opposite recesses, lugs on the` rim member engaged in respective recesses, and, noneresonant material interposed vbetween Y the rim member and core.

' 4. A wheel forpreventing the transmission Vof sound `vibrations embodying a rim member, a core,rlugs Von the Vrim member' Y bearing against a portion ofthe outer face of the core and interlocking with the latter, Y

In testimony whereof I aiiix my signature, in the presence of two subscribing witnesses.
