Abstract: 10,150. Glad, G. H., and Schumm, F. May 1. Obstruction - removers. - A lifeguard for street cars, automobiles, locomotives, &c. consists of a cradle which is carried in a frame on brackets beneath the car and is shot out to catch the obstruction when released by a feeler frame. Fig. 1 is a sectional view of the car brackets ; Fig. 2 a section on the line 2-2, Fig. 1 ; Fig. 3 an underside view of the cradle frame; Fig. 7 an underside view of the complete lifeguard without its lower casing ; Fig. 10 a section on the line 10-10, Fig. 7 ; and Fig. 13 a front view of the apparatus with the cradle removed. The car brackets 2 have hinged extremities 3 and are joined by plates 5, 4, the latter of which carry sockets 11 for the rearwardlyextending pins 10, Figs. 3 and 10, of the cradle frame. The cradle frame is locked in the brackets by a lever 17, Figs. 1 and 2, the forked end 16 of which passes through long slots in the plate 4 to the plate 14. A spring 20 normally holds the plate 14 down in the slots, but, by raising it, the pins 10 may be disengaged from the sockets 11 and the front of the fender frame may be raised by turning it about the hinges of the arms 3 and it may be held out of use by engaging the bar 40 under the hooked end 21 of the lever 17. A spring 50 assists the ejection of the pins from the sockets 11. The cradle 26, Figs. 3 and 10, is normally retained at the top of its supporting-frame 7, 8, 9 by weak springs 31, and it is shot downwards by powerful springs S when the feeler bar 40, Figs. 1 and 2, is pushed in. This is effected by cams 44 on the feeler which move laterally a bar 36, Figs. 10 and 13. The bar 36 slides on a ledge 37 of the bracket plate 4 and has a twofold function, namely, to hold the cradle up by the engagement of its ends 35 under lugs 34, Fig. 3, on the cradle, and also to prevent the springs S from acting. The bar is held in its normal position by a spring 38, and, when moved aside by the cams 44, it frees the cradle and, by means of wedge blocks 66, Fig. 7, releases triggers which control the springs S. One of the triggers is shown in Fig. 16 ; it consists of a spring-pressed pivoted plate having a circular boss 65 for engaging the wedge 66, and a toe 59 for lifting a plate 62, which slides behind a plate 61 fixed at the end of the fender frame. The spring S abuts at the top on a fixed stop 53 and at the bottom on a collar 56 on a flexible rod 52, which it embraces. The collar abuts on the plate 61 until the latter is raised by the action of the feeler cams, the bar 36, and the trigger. When this occurs, the collar is forced freely through a wide opening in the plate 61, Fig. 3, so that the lower end of the rod 52 enters a socket 57, Figs. 3 and 10, on the cradle frame, and so lowers the cradle. The cradle is kept extended by spring-pressed triggers mounted on the brackets 2, and it is supported by rollers on arms 32, Fig. 10, which pass through slots in the casing C. The triggers may be raised by hand when it is desired to slide the cradle back to its " set position, and a lever 73, Fig. 13, is provided for actuating the bar 36 by hand.
