SPECIFICATION fOI'mng part 0f Letters Patent N0. 670,712, dated March 26, 1901.
lApplioation filed NOVembI 10, 1900- Serial No. 36,058. (No model.)
To all whom it may concern:
Be it known that I, ROBERT KUHN, a citizen of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new Iand useful Improvements in Trolley-Wheels; and I do hereby declare that the following is a description of the invention sufficiently clear, full, and eX- act to enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form also a part of this speciiication.
The object of this invention is to protect the faces of trolley-wheels, the means used for the purpose being separable from other parts of the wheel, and therefore independently renewable, so that as long as this latter remains otherwise in good condition it will not have to be discarded by reason of a worn-out rim or face. f
These trolleywheels wear rapidly at their rim, which travels in contact with the electric conductor or wire, and they have to be replaced at frequent intervals on account of this excessive wear conned to a limited surface only, while all other parts remain yet in good condition. .My invention removes this objection and permits a trolley-wheel to be used much longer and until the same has become useless from general wear in all its parts.
In the following specification, and particularly pointed out in the claims at the end thereof', is found a full description of this invention, its parts and construction, which latter is also illustrated in the accom panying drawings, in which- Figure l is an edge view of a customary trolley-wheel provided with the features of my invention. Fig. 2 is a side View of the preceding figure. Fig. 3 is a view similar to Fig. l, the wire covering being shown in section and the construction for securing the ends thereof being slightly modified. Fig. 4. is a side view of the preceding ligure with parts broken away. Fig. 5 is a sectional detail view showing a modified form of my invention. Fig. 6 in a central cross-section shows the construction of the wheel used in 5o connection with my invention.
In order to protect the grooved face of trolley-wheels, I provide a wearing-surface between the lateral iianges forming said groove of a material which forms an independent part and is separable from the wheel-body, so that it' worn out it may be removed from the latter and replaced by another. rlhis wear- `ing-surface is provided by covering said rim W or face with one or more layers of wire, as 6o shown in the drawings. One layerI consider sufticientin most cases, which,with the bights resting against each other, is closely wound around the face of the wheel and may when worn out be renewed by simply rewnding the wheel. Thefends et' the wire may be secured and heldin various ways. As shown, I provide lugs 7, one at each side of the wheel, within perforations of which a wire end is heldby a set-screw 8, or the end might be 7o knotted to prevent it from slipping through the opening in said lug. From the lug on one side the wire is then taken over the edge of the wheel, wound closely around the face ot' it, and secured to a similar lug on the other side thereof. Wherever it passes around the edge of this latter it is desirable to provide a notch 9. In this case one continuous piece of wire would be used. Two pieces of wire may also be used, as shown in Figs. 3 and 4, 8o
one end of each being started midwayin the deepest part of the groove of the wheel. In such case these inner ends might be held within an opening l0 in the body of the wheel,
the holding means-a wedge l1,for instance- 85 being applied from an opening through the side or from the bore of the hub, as shown in Fig. it. The. outer ends may be held as before described. There might also be a separate opening l0 for each wire end. The wire 9o so protected may also be made much lighter than the ones at present constructed by cast ing, and the body thereof might be made of A t-rolley-wheel sheet metal, as shown in Fig. 6, the various converging toward the deepest part of it and parts being formed to proper shape'bystampare wound with wire, the coils of which rest ing or otherwise. on said sides and also against each other, the
