T0 aZZ whom it may concern;-
Be it known that 1,-HENRY J. ROHRBAOK, a citizen of the United States, and a resident of Chicago, Illinois, have invented new and useful Improvements in Safety Attachments for Cable Cars, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, likeletters indicating similar parts on the different figures.
The purpose of the present invention is the providing of simpler and more effectual means for preventing people from being run over by cable cars. The means now employed consist of a guard suspended from the car-frame to apoint as close to the track as it can with safety be run in all conditions of the roadway, which is not so close as to be serviceable in removing a person without the limbs or some portion of the clothing getting under the guard, and thereby preventing the person from being moved or carried by the pointed end of the guard from the place of greatest danger. At present the devices are intended to throw a person to the side of a car; but, as double tracks and double lines of cars are used, aperson thrown to one side is very liable to be run over by the grip-car running in an opposite direction. The necessity of having some device or apparatus for attaching to cable cars running in th ronged streets, to prevent accident to pedestrians, is assumed to be admitted by the public. Therefore the invention will be treated as useful as well as new. The guards on the cable-cars do not differ from the pilots or cow-catchers in front of locomotives, ex cept that the guards extend along the sides of the cars, there being no means for elevating or depressing either of the devices when the cars or locomotive are. in motion-that is, whatever means there may be for adjusting the height of the protections employed. Such means are not within the graspof the drivers.
My invention consists of a double-ended guard,which is suspended fromtheframe-work of the grip-car, and which, by suitable mechanism under the control of the driver, can be lowered at will so closely to the track as to prevent a person caught by it from being drawn under it, and at the same time the guard can be thrown forward, so thatthe shock shall come wholly on the guard, which may be filled in with chains or elastic straps, which will largely relieve a person from the concussion. My theoryis to keep the persons caught on the car tillit can be stopped, instead of employing means for throwing them to one side, where they are liable to be run over.
Figure 1 is a perspective representation of the principal portion of the safety attachment removed from theicarlto'givej'a clearer v u of its construction; Fig. 2, an iiuverted pl of an ordinary grip-car with my safety attachmentfln proper' position in relation,=,thereto; Fig. 3, a longitudinal central sectional elevation of the grip-car and safety attachment.
A A B B represent a substantial frame, which I prefer to construct of metal, to fit in between the car-wheels and above their journals, and of such length as will bring the guards O D to about even with the ends of the car.
The guards O D are preferably made concave in front and filled in with chains, rods, or some elastic cords or straps, whereby a person brought in contact therewith will not be injured. It will be noticed that the ends of the guards are 'in'clinedoutward, so as fully to cover the track, thereby rendering it impossible for a person caught in front .of the grip car to be run over by it.
Rods E are attached to the ends of the guards O D, and on them are placed a series of rollers, F, which are brought to and run on the roadway when the guard is brought down and for ward for use, and is thus prevented from being caught by ordinary obstructions.
The sides A A of the frame are suspended from the timbers G G of the grip-car in part which are attached to cross-bars I I on the frame-pieces A, by which attachments it will be observed that the springs are considerably inclined; in fact, so much so that the springs hold the whole frame and guards evenly under thecar.
Pivoted to the side timbers of the car is a K, to the free ends of which pins or anti-friction rollers b, below the frame-pieces A A, and pins or rollers a, above the said pieces, are affixed to lower the frame, and the lower pins or rollers, by means of springs c, assist in holding the frame up when not required for use.
rock-shaft, J, to which are affixed two arms,.
by means of coil-springs H, the lower ends of 0 Arms L L are also rigidly attached to the shaft J, and their free ends M project up through the floor of the car in convenient position for the driver to put his foot thereon, as more clearly shown at Fig. 3. The effect of pressing down on the part M is to bringrthe racks N on the frame-pieces A down into mesh with the pinions O on the journals P of the carwheels R, and as a result of such movement the frame and guards are moved forward in the direction the car is moving till the rackslip gear and the forward guard remainin that forward position till the lever or arm L M are released.
My invention embraces the downward and forward movement of the guards, and itisevident that the same result can be accomplished by jointing the frame pieces at their centers and employing adouble set ofarms to-depress- This construction issuch' I the section-frame.
on rods E, in combination with spring H c,
and arms K and L M, as and for the purpose specified.
2. The double-ended guardsfl- Dg-linhombination with the frame provided with racks N the gear'orpinions O, and levers or arms K L M, and springs H c, substantially as specified 3 5 and shown. 4
