SAFETY APPLIANCE FOR STREET CARS.

Specification of Letters Patent.

Patented Aug. 8, 1922.

To all whom it may concern:

-. by the air will be applied to the brakes and the brakes applied, when. the trip is actuated.

Another object is to provide an attachment of'the class described through which the brakes will be automatically applied when the fender trip strikes an object on the track in front of the car.

With the above and other objects in view the invention has particular relation to certain'novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1, is a fragmentary vertical sectional view of the front end of a street car showing my attachment applied thereto, and,

Figure 2, shows a diagrammatic view of the air brake system of street car showing my improvement thereto.

Referring more particularly to the drawings the numeral 1, designates the car, which has the floor 2. Depending from the front end of the car are the brackets 3, one on each side. A. bearing rod 4 has its ends anchored to these brackets and the depending fender trip 5 is swung on said rod. This trip extends entirely across the car and just clears the track 6. It is of the usual and well known construction.

Behind this trip there is the usual fender 7 which extends entirely across the track. It is formed of the wings 7', 7 at right angles to each other, one being normally vertical and the other horizontal. It is pivoted between the depending side brackets 8, 8 which are secured to the bottom of the car. A latch 9 is pivoted to one of the brackets 8 and one end then engages over the upper edge of the vertical wing 7'. The other end of this latch is turned downwardly and one end of the release rod 10 is pivoted thereto. The other end of this rod is pivoted to the arm 11 which is fixed to, andv upstands from, the rod 4:. A strong pull spring 12 is attached, at one end, to the vertical wing 7" and at its other end it is attached to the car floor in front of the fender.

The numeral 13 designates the re-set rod. This rod is pivoted at one end, to the vertical wing 7 and at its other end to the upper end of the reset lever 14. This lever is pivoted to one of the brackets 3 and its lower end is curved rearwardly. The push rod-15 is pivoted at its lower end to the curved end of the lever 14. and its upper end works through-a bearing in the car floor and is formed with a pedal by means of which it may be depressed by the foot of the motorman. lVhen the trip 5 strikes an object on the track it is forced rearwardly, carrying the arm 11 forwardly and exerting a forward pull on the release rod 10. This releases the latch 9 and the fender will then be tilted forwardly by the pull spring 12. The horizontal wing 7 will drop down on. the track and pick up the object and pre vent it from being run over by the wheels behind the fender. The fender is of a basket like structure and large enough to hold the human body or object of like size.

The fender is reset by depressing the push rod 15. When this rod is depressed the. reset lever 14 will exert a rearward thrust to there-set rod 13 and this will re store the fender to original position. The upper edge of the vertical wing 7 will strike against the bevelled end of the trigger 9 and elevate said end into position to engage over the upper edge of said wing. As the trigger is elevated a forward thrust will be imparted to the release rod 10 and this will operate through the arm 11 to restore the trip 5 to original position.

The street car is equipped with the usual air system which includes a main reservoir 16 and the usual air tubes or pipes. The construction and arrangement of this system is well known and need not be described in detail. It includes, however, the safety air line 17, and the main air line 18, which leads to the reservoir 16.

The safety air line is connected into one end of the valve cylinder 19 through the pipe 20 and the main air line 18 is connected into the side of said cylinder through the pipe 21. Within the cylinder 19; there is a sliding plunger-like valve" 22 wliiclrnor mally cuts off communication between the,

pipes

20 and 21 as shown in Figure 1. The valve 22 is fixed to a stem 28,. An actuating rodQl is connected, at one end, to the free end of the arm 11 and its other end is at tached to a pull spring 25 which is connected to the bottom of the car. This rod is also 'c'onne cted'to the valve stem. When thetrip S strikes an object a pull is exerted through the rod 2%- and' the stem 23 and the valve is pulled outwardly in the cylinder 19 beyond the 51 3921 thus connecting the main air' unearth the safety air line and the emergency brakes will be thereby applied "and the car at once stopped;

one endof which is upwardly beveled and notched to engage over' the edge of one of said wings, and-"an arm fixed to and upstafnding from saidrod, a release rod pivoted at'"one end to the other end of said latch and pivoted at its other end to said arm, apull; string attached at one end to said last-mentioned wing of the fender and attached at its other end to the car in front ofthe fend er, a reset rodpivoted at one end to slaidflast mentioned wing, a reset lever pivoted to a suitable bracket carried by thefront end of the car the other end ofsaid reset rod being pivoted to the upperend of said resetlever, a push rod working through a bearing in the car floor and pivoted at its lower end to the other end of said reset lever, and whose upper end is formed into a peda 2. The combinationwith a street car of a rotatable t an ve se b g rod Carried by the front end of the car, a tender trip depending from said rod, a fender depending from the car behind said trip formed with wings extendingat substantially right angles to each other, said fender being pivotally mounted and extending entirely across the railway track, a latch pivoted to the car, one end of which is upwardly beveled and notched to engage over the edge ofone of said wings, and an arm fixed to and upstanding from said rod a release rod piv-- oted at one end to the other end of-said latch and pivoted at its other end to said arm, a pull spring attached at one end to said last mentioned wing of the fender and attached at its other end to the car in front of the fender, a reset rod pivoted at one end to said last mentioned wing a reset lever pivoted to a suitable bracket carriedby the,

front end of the. car the other end of said reset rod being pivoted to the upper end'of' said reset lever, a push rod'working. through a bearing in the car floor and pivoted at itslower end; to the other end of said reset lever., and whose upper end is formed into a pedal, an airbrake system embodied in the car and including a. main. airline, and a safety air line, a valve norm-ally blocking communication between said lines, and a connection between said fender trip and valve. whereby the. movement of the. formerwilli actuate. the latter to establish communication between said lines. i
