PROTECTING-PLATE FOR SPOKE-SOCKETS.

SPECIFICATION forming part of Letters Patent No. 486,995, dated November 29, 1892.

Application filed August 5, 1892.

To a/ZZ whom t may concern:

Beit known that we, ERNEST WEINMANN and FRANK LINDHoRsT, ofthe city of St. Lou' and State of Missouri, have invented certain new and useful Improvements in Protecting- Plates for Spoke-Sockets, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to improvements in protectingplates for spoke-sockets; and it consists in the novel construction and combination of parts morespecifically set forth in the specification and brought outin the claims.

Figure 1 is a perspective view of a felly and spoke with parts broken away, having our iuvention applied thereto. Fig. 2 is a transverse section of a felly, protecting-plate, and spoke, showing the several parts united. Fig. 3 is a perspective view of the protecting-plate; and Fig. 4 is a transverse section of a felly and plate, showing a modification.

The object of ourinvention is to construct a protecting-plate in such a manner that the same can be applied or interposed between the shoulder formed on the lower end of the spoke and the inner surfaceof the felly adjacent to the opening formed in the same for the reception of the reduced extension of the spoke. By the use ot' our invention, when applied in the manner as hereinafter stated, the felly is prevented from splitting at either side of the opening formed in the same-a thing of repeated occurrence on wheels generally; and, further, the spoke is prevented from Wearing into the felly and causing the said spoke to become loose.

Referring to the drawings, 1 represents a felly having an opening 2 formed therein for the reception of the decreased extension 3 of the spoke 4.

5 represents a metallic plate, preferably formed of a single piece, and is of such a thickness as to adapt itself for the purposes hereinafter stated. The said plate 5 is pro` vided with a Hat surface 6, against which the shoulder 7 of the spoke 4 comes in contact, in which instance the said shoulder will not rest directly upon the felly, as ordinarily it does. The fiat surface 6 extends a suitable distance beyond the shoulder of the spoke,

Serial No. 442,238. (No model.)

is inserted into the opening formed in the felly. Thus it will be seen that the said protecting-plate is interposed between the shoulder 7, formed on the spoke and the inner surface of the felly. On either side of the felly, opposite the opening2 therein, are formed two semicircular depressions 9, which are shallow and form shoulder 10 at a suitable distance from the outer edge 11 of the felly.

Referring again to the protectingplate2 12 represents two downwardly-projecting lips, which are formed integrally with said plate and are bent at right angles with the ilat surface 6 of the sanne.l The edges 13 of the sald lips are of such a thickness as to till the space or semicircular depressions 9, the said edge 13 coming in contact with shoulders 10, formed by the said depressions, as best shown in Flg. 2. The edges of said lips are curved to conform to the curved depression 9, formed-1n the felly, and adjacent to said curved edge the lips are beveled up to the edge of the shoulder 10, as shown at 14, which prevents the said plate from being abruptly struck, or, in ore properly, the lower edges of the lips forming a part of the same by obstructions 1n the street as the wheel turns.

The protecting-plate subservesa very irnportant function in that it prevents the spoke from working into the socket by heavy Jolts during the travel of the wagon on a rough road, and as a result splitting the felly around the socket, and thus loosening the tire. v Accordingly, the plate acts as a spoke, felly,and tire-protector.

In the modication shown in Fig. 4 the depressions 9, formed on the 'opposite sides of the felly 1, are of a depth ycorresponding to the thickness of the lips 12 of the plate 5, whereby the outer surface of the said lips and the corresponding vsurface of the felly are Hush or in a line with one another. The lower edges 13 of said lips are beveled to an edge and are-litted in correspondingly-shaped shoulders 10, forming the curved wall of the de- IOO pressions 9. By this construction it will be seen that'the lips 12 are prevented from being bent in any manner and are held snugly against the opposite surfaces of the telly, which is necessary for preventing lthe said telly from splitting.

Having fully described our invention, what we claim is- A 1. In combination with aspoke and telly, a plate 5, having a iiat surface 6, an opening` 8, formed in the said plate for receiving the reduced extension of the spoke, lips formed on the opposite sides of the4 said plate and provided with beveled edges 14:, and semicircular depressions 9, formed on the opposite sides of the felly forming shoulders 10,-the depth of said shoulders corresponding to the thickness In testimony whereof we aix our signaturesV in presence of two witnesses. y
