(Cl. 246-216) This invention relates to a rail-torpedo fork and more particularly to such a fork adapted for the positioning of torpedoes on the rails of a railroad track for use as a signaling device. A primary object of this invention is the pro vision of an improved torpedo fork which will permit a torpedo to be placed on a rail from the rear of a moving train. 2 From the foregoing, the operation of the de vice should now be readily understood. A conventional torpedo 23 is placed on the top surfaces of projecting members [9, its spring arms engaging notches 22, this operation tak ing place upon the moving train. The fork I0 is then extended from the rear‘ of the moving train by handle II which, it may here be pointed A further object of this invention is the pro out, is of a length sufficient to reach conven vision of such a fork which will reliably secure 10 iently from the rear platform of the train to the the torpedoes to the rails while the train is travel rail. Portions I 6 are then placed on opposite ing at relatively high speed. sides of the rail and slide therealong until a A still further object is the provision of such quick downward pressure is exerted on handle a device so designed as to be readily disengage ll. Such downward pressure releases the spring able from the rails after the torpedo has been 16 arms 22 of the torpedo from the notches 2| of seated thereon. projections l9 and permits the same to clamp An additional object resides in the provision ?rmly in position about the ball l8 of the rail. of a torpedo fork which will be e?icient and reli The device then slides along the rail until a able in operation, sturdy and durable in con rail joint is reached, whereupon portions l4 en struction, and relatively simple and inexpensive 20 gage the same and cause the arms to slide up to manufacture. wardly about curved portions l5 to disengage the Other objects will in part be obvious and in fork from the rail.

In practice, it is sometimes essential to utilize In the accompanying drawing, wherein there 25 two torpedoes to convey a signal to a follow is shown a preferred embodiment of this inven ing train. For this reason it is desirable ~to keep tive concept: two forks loaded in order that the second fork Figure 1 is a, perspective view of the torpedo may be utilized to place a second torpedo at a fork, certain portions thereof being broken away, and Figure 2 is an end elevational view of the fork shown in association with a rail torpedo and a distance ahead of the ?rst, while 80 predetermined the first fork is being reloaded. It will now be seen that the use of this device permits the placing of signaling torpedoes with railroad rail, the latter being shown in section. out the necessity of stopping the train, and that Like reference numerals refer to like parts such torpedoes may be placed accordingly, with throughout the several views of the drawing. 85 out the necessity of sending a brakeman or other Having reference now to the drawing there is operator back up the track to the rear of the generally indicated at ill a torpedo fork comprised train in order to provide a suitable margin of of a handle, a portion of which is shown at H, safety wherein a following train may stop. Thus having secured thereto as by a screw I2, a bifur the device may be used at the ?rst indication of cated fork member comprised of a transverse 40 stopping a train and the torpedoes so positioned portion [3 adapted to abut the handle and two parallel bars l4 extending therefrom. Members 14 are bent or curved as at l5 to form angularly disposed extending portions l5, adapted to be a material distance behind the point at which i ‘ the rear end of the train ?nally comes to a stop ' ' in order that a following train may be given ample warning of the obstruction to the line. positioned, in a manner to be described herein 45 From the foregoing it will now be seen that after, on opposite sides of a railroad rail I’! there is herein provided a device achieving all below the ball I8 thereof. Projections 19 extend the objects of this invention and many others upwardly at right angles to portions l6. Each of projections I9 is provided with an outwardly ?ared ?ange 20 and a notch 2| in the top wall thereof. Notches 2| are adapted to engage the depending spring arms 22 of a conventional rail torpedo 23, flanges 20 serving to prevent dis alignment of spring arms 22. including advantages of great practical utility. . As many embodiments may be made of this inventive concept and as many modi?cations may be made in the embodiment hereinbefore shown and described,it is to be understood that all mat ter herein is to be interpreted merely as illus 65 trative and not in a‘limiting sense. 2,412,746 3 _, , 4 l furcations spaced to loosely straddle a rail; said furcations having their outer extremities bent upwardly,‘ beveled recesses in the‘outer surfaces I claim: 1.
