LIFE-SAVING GUARD FOR CARS.

SPECIFICATION forming part of Letters Patent No. 527,270, dated October 9, 1894.

Application filed November 20, 1893. Serial No. 491,517- (No model.)

and I hereby declare that the following is a' full, clear, and exact description of the same. I

The object of this invention is to provide a trolley, cable or tram-car with a guard which, in the event of a person getting in front of or in the way of a moving car, will pick up and carry the person until the car can be brought to a standstill, or the person removed from danger.

It is also part of the object of my invention to so arrange the guard that it can be raised into and carried in a vertical position during the travel of the car when not required for service, and also to so arrange the guard that it can be instantaneously lowered to approximately the level of the rails the moment it is required to remove or pick up the person or object in danger of being run over by the moving car, and also to so arrange the guard that if desired it can be carried permanently in its lowered position; and it is also part of my invention to so arrange a switch in conjunction with the mechanism operating the trolley guard, that during the lowering movement of the trolley guard the operating mechanism will instantaneously cutoff the circuit of the electric current from the motor, and during the raising of the trolley guard the operating mechanism for the same will move the switch to cut in the electric current to the motor, and also to so arrange the switch that it can be moved independently of the mechanism operating the trolley guard, in order that it can be operated at the will of the party running the car, the whole device being constructed and'arranged as hereinafter more fully set forth and more particularly guard in its raised position.

spective view of a section of the platform showing the switch mechanism, and Fig. t is a View of the under side of the same. Fig.5

and beneath thesame are two hangers respectively 2 and 2 provided with bearings 3 and 3 respectively for the spindle 4:.

The spindle 4: is supported in the bearings 3 and 3 and extends from side to side of the platform 1 and about midway between the under side of the platform and the level of the roadway. Removably fitted to the one end of the spindle 4 is a bracket 5, and removably fitted to the opposite end of the said spindle is a bracket 5".

Formed within the bracket 5 is a slot 6, and rigidly secured within the slot 6 are the ends of two blocks 8 arranged one on either side of the side bar 7 Passing through the blocks 8 and the side bar 7 is a bolt or pin by means of which the side bar is pivotally connected to the blocks 8 The bracket 5 is provided with a similar slot 6 to receive the ends of two blocks 8*, arranged one on either side of the side bar 7", the side bar 7 being connected to the said blocks in the same manner as the side bar 7 is connected to the blocks 8*. I

Passing around the blocks 8 and side bars 7 is a clip 9 binding two springs 10 to the side bar 7 and blocks 8 while a similar clip 9 binds two'springs 10 to the side bar 7 and blocks 8*.

The side bars 7 a and 7 are continued around the front of the guard and are welded, or

otherwise secured, together and form the front 11 of the guard. I may, however, if I so desire, make the side bars and front of one continuous piece of metal.

The front 11 of the framework of the guard it on the net work of the guard without causing it serious injury.

Connected to each of the side bars 7 and Inclosing the cross bar 14 and the spindle 12, and connected to the front-11 and side bars 7 a and 7 is a covering 15 of canvas or other suitable material, which provides what might be termed a floor or platform to receive the object picked up by the guard.

the dash board are a series of horizontal arms 16 and supported in the arms 16 is a bar 17 parallelwith thefront 11 of the framework and extending entirely across the front of the dashboard.

Connectedto one end of the bar 17 is one.

work of the-guard when the guard is in its lowered position.

Connected ito-the front end of thef-rame work of the ,guard or to the canvas-covering 1-5is the lower end'of the front-0f a netting.

20,'whileithe upper-end 'of the fronto'f the netting 20 is connected to the flea-r1 7. The lower ends of .the sides :21 of :the'netting '20 are secured and 7 Connected to the "bar. 1-7 -at or'near itsmiddle is'one end of a rubber "or "e'lasticcord 22-, while the opposite end of the said cord 22 is secured to the :bar let-or canvas covering 15.

Connected to the bar17'at regular intervals between its "ends are the uppe-rends ofa series of stay cords23, whileth-e-lower'ends o'f the stayc'ords 23 are connected to the cross bar 14 or canvas covering 15.

tween the bearings 3* and 3 of the rhangers s2 and :2 respectively is a-counter balance. 'orba-lance weight :24: which is intended to;

' balance the weight of the :guard and automatically raise the guard into a vertical pos'ition when not "required for use. Rigidly secured to 'thespindle 4 is a bell cranklever 1, and the upper end of this foot lever '26 passes through a slot'formed :in the'platform'. 1. Thefoot lever 26 is-fitted on its upper:

end'with 'a' pedal 29.

"The 'slot in "the platform is fitted with a metallic plate 30 'having a correspondingslot. 28 in order that the lever will -not wear away respectively tothe side bars 7, might be stated, being locatedon theunder the woodwork of the platform, and at one end of the slot '28 in the plate 30 is arrecess 31 and at the opposite end of the slot 28 is a recess 32 and into each recess enters the foot lever 26 when at its respective end of the said slot. By means of these recesses 31 and 32 the lever 26 is rigidly held at the desired end of the slot, and the guard by thismeans is held either in its raised or lowered position as required, and the lever is held in either of the said slots by a spring 26. Explanatory of this it might be stated that by moving the Connected to the top of the" outer side of foot lever 26 to the forward end of the slot as shown in Fig. 1 of the drawings, the guard is lowered into the position shown in the said Fig. 1 and is there held until the foot lever. is removed from th-erecess 31, and the counter balance raises the guard into a vertical position. Whenever the lever is moved to the rear or-opposite endof the slot and enters the recess 22 theguard is lifted into the vertical positionshown in Fig. 20f thedrawiings.

As before stated the counter balance 24Lis intended to balance the framework of the guard, and immediately the foot lever has been released from the recess 31 the counter balance commences to lift theguard into a vertical position. The only force that is required in the operation of the apparatus is suffi'cient pressure-for the forward movement :of'the foot lever, which is so slight that it amounts to nothing,the apparatus being so evenly-balanced. Connected to the footlever 26 is a'spring 33 which operates the switch 34 cutting the current into or out-of circuit with the motor, the switch mechanism, it

-'side of the floor-0f the platform with a small knob extending through-a'slot in the floor of theplat-form and moved by the spring 33.

I The object of the Wheels 13 on ltheslpindle 12 is "to prevent the front of the guard striking the ground during the oscillation :or

swinging of the'car whiletraveling'over uneven ground, and the object of the-springs s10 zand-lO is to reduce the strain on the frame- Mounted upon the spindle 4t mediately be work of the guard when the car comes in contact with an obstacle of any description whatsoever. The netting 20 extends entirely across the front of the car, and is sufliciently flexible and soft "to receive a body without causingitserious injury. 7

In Fig.7 I have showna spring to serve the same purpose-as thecounter balance24.
