Title: Improvements in Fenders for Tramway and like Vehicles
Inventor: DOW FRED FORD
Filed: 1901-03-26
Granted: 1901-06-22
Abstract: 6339. Lake, H. H., [Dow, F. F.]. March 26. Obstruction-removers or fenders for tramway and like vehicles. Fig. 1 shows an elevation, and Fig. 2 a plan of one side. The side bars 41 of the fender frame are gripped by clips 5, 51, Fig. 4, by which they are pivoted at 6 to brackets 3 secured to the ends of rods 1 guided so as to be capable of sliding in, preferably, the car truck. The side bars 71, 100 of a pilot frame 7, and htching- frame 10, slide telescopically in the bars 41, and are fitted respectively with projecting pins 72, 101. The normal working position of the fender, shown in full lines, is preserved by the engagement of the pins 72 and 101 with stops 81 and latches 82 respectively, these stops and latchei being formed on plates 8 secured to the brackets 3. A leaf spring 103 holds the pins 101 to the right under the latches 82. In operation, the impact of an obstruction first drives back the frame 10, releasing the pins 101 and so allowing the frame to be tilted by the spring 9 so that the pins 72 clear the stops 81. The frame 7 is then retracted by the springs 9, and the whole frame may also slide rearwardly through the friction clips 5, 51. If now the obstruction, a man for instance, fall on to the frame, his weight comes chiefly behind the pivots 6, and therefore causes the frame to assume a safe horizontal position. Catches 31 may be provided to engage the pins 101 when the fender is in its inoperative position under the car. Stops limit the movement of the bars 41 through the clips 51, 5. The latch pins 101 may be released by a lever B.
