CAR-FENDER.

SPECEFIGATION forming part of Letters Patent No. 548,631, dated October 29, 1895.

Application filed August 5, 1895.

To @ZZ whom t may concert/b:

Be it known that I, JOHN HENRY DOERR,a citizen of the United States, and a resident of Camden, iu the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Trolley-Car Fenders, of which the following is a specification.

The invention mainly consists of a pneumatic rubber roller extended laterally across the forward end of the car-body between the rails of the road-bed, over and upon which the car is propelled in its forward movement, said roller being supported by journals at its extremities, which have bearing in a suitable framework or housings for their support, which are projected outward longitudinallyin front of the car-platform and wire fender, said fender and roller having pivotal connection with the car-platform in brackets extended therewith. At each extremity of the roller and rigid thereon are wheels, whose peripheries are channeled in such a manner that they engage with the corresponding flanges of the car-wheels contiguous thereto, which in their revolutions during the propulsive movement of the car cause the roller to revolve in conjunction therewith. This roller is provided with a series of projections arranged at equidistant points upon its periphery in such manner as to engage with and carryover upon the fender any mass, portion of matter, or body resting upon the road-bed which would obstruct the forward movement of the car. The weight of said matter or body when carried over upon the wire network of which the fender is composed causes it to lift the roller upward by reason of its pivotal connection in its bearings of the framework, thus removing the body of mattei' or other obstacle upon the roadway out of the course of the passage of the car and from the consequent danger of injury. The entire framework and roller are connected by a bolt to the end crosstirnber of the car-body to allow of a swivel movement of the mechanism during the passage of the car across switches or in rounding curvatures of the track. The wire-network fender is also provided with a segmental curved portion extending downward in the rear of the pneumatic roller, whose lower edge Serial No. 553,284. (No model) is but slightly elevated above the surface of the roadway, which precludes the passage beneath the fender of any obstruction to the forward movement of the car, as will be more fully understood from the following detailed description and accompanying sheet of drawings, in which- Figure l is a side elevation of a portion of the platform of a car-body, showing the improvement in connection therewith. Fig. 2 is a plan View of the same. Fig. 3 is a perspective view of one end of the pneumatic roller D, showing one of the metallic pieces K, which is provided with the groove or channelf.

Like letters of reference indicate the same parts.

A is the forward end of the platform of the car-body, to which the cross-brace timber is secured and forming an integral part therewith.

B is a metallic bar, whose main portion is semicircular in contour, and whose parallel ends or arms b b are extended in the same plane, projecting from the sides of the platform A, so as to form bearings to support the hangers or pedestals c c', which support the car-axle C, and also the pneumatic roller D, by means of its journals d d revolving in bearings in said pedestal c. This roller D is furnished upon its cylindrical surfacerwith a series of short spike-like knobs e, so arranged circumferentially thereon as to engage during its revolutions as the car is propelled with any foreign body on the roadway and lift the same upward and upon the wire-network fender E out of the pathway of the car and from the danger of injury. At each end of this roller D and fast thereon are the metallic circular pieces K, each having an annular concentric groove f in their peripheries, into which the Hanges of the car-wheels O of the axle enter, and as the weight of the roller bears the pressure thereof downward and upon said flanges the roller is thus caused to rotate during the movement of the car and carry any body or obstruction from the surface of the track.

The mechanism and attendant supporting portions have swivel connection with the roo framework of the ear by means of the bolt G, which passes through the spur II into the cross-brace timber J, forming a portion of the framing of the ear-platform, by which means the fender and parts attached may be given a swivel movement during the passage of the car over switches and around curvatures of the roadway. In the rear of and of equivalent curvature in its segmental area is the downwardly-projecting portion E of the fender forming part thereof, whose lower edge is but slightly elevated above the surface of the rail, and which acts as a guard that would prevent the passage beneath the car of any body or mass of matter presenting an obstruction to the passage of the car or an injury to the operation of' the roller or fender in removing the obstacle.

In some cases the fender may be connected directly with the draw-bar of a carcoupling,

thus dispensing with the link.

I claim as myinvention and desire to secure by Letters Patent- 1. The pneumatic roller D, supported in the bearings o', on the ends b, of the bar B, and having its surface furnished with the conical, or pyramidal projections e said roller having the annular grooves f, in the pieces K, upon its ends, that bear against and revolve with the ange of the car Wheel C', for the purpose of rotating said roller, substantially in the manner and for the purpose herein shown and described.

2. The combination of the roller D, constructed as herein shown and described, having the annular grooves f in its ends in the pieces K, and revolving with the anges of the Wheels C With the fender E, provided with the segmental lower portion E', extending downward to a point near the surface of the car rails, with the draw-bar of a railway car, substantially in the mannerherein shown and described for the purpose set forth.
