GIDEON A. COPP, OF CHICAGO, ILLINOIS.

DEVICE FOR PREVENTING TRAlN-ROBBERIES.

SPECIFICATION forming part of Letters Patent No. 722,494, dated March 10, 1903. Application filed September 25, 1902. Serial No.124fl26- (No mcdelo To all whom it may concern:

Be it known that I, GIDEON A. (JOPP, a citizen of the United States, and a resident of Chicago, Illinois, have invented certain new and useful Improvements in Devices for Preventing Train-Robberies, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide means on locomotives by which the engineer without leaving his station in the cab and without using his hands may cause a discharge of hot water or steam onto any persons attempting without authority to mount either the engine or tender or the forward platform of the first car behind the tender or who from any nearby position on the ground by means of threats and display of arms undertake to compel the engineer to stop or reverse or otherwise according to their demands control the action of the engine.

It consists in connections with the boiler, terminating in discharge-nozzles in proper positions to effect the above-stated result, having valves for controlling their action located where the engineer, either by the movement of his body or feet, may operate them from" his usual station.

It consists, further, in details of construction set out in the claims.

In the drawings, Figure 1 is a partly-sectional side elevation of a portion of a locomotive with its tender and the forward end of the first attached car, section being made at afore-and-aft vertical plane through the locomotive-cab. Fig. 2 is a section at the line 2 2 on Fig. 1. Fig. 3 is a section at the line 3 3 on Fig. 1. Fig. 4is a detail section at the line 4 4: on Fig. 2. x

I prefer to apply my invention in such manner that hot water may be discharged from the boiler upon intruders, and for this purpose I lead from the boiler below the waterline at each side a pipe 1, such pipe constituting a loop connected at both ends to the boiler. It extends in any convenient position out of the way of the engineer and fireman, preferably first up to the top of the cab, then rearward to the rear corner, and then along the rear edge, as seen in Figs. 2 and 3. If

preferred, for reasons which will hereinafter appear, this pipe may be branched from a point near'its connection to the boiler and each branch may be controlled by a separate valve, as hereinafter explained. When this construction is adopted, this being the structure as shown in the drawings, one of the pipes, which for the sake of distinction only may be termed the branch pipe 2, has nozzles 3 3 at or near the rear the rear corners of the roof of the cab directed so as to throw a jet over the tender in a direction to reach the front platform and steps of the car'A. The main pipe 1 is provided with nozzles 4 4 at the opposite sides of the cabroof, overhanging the entrance to the cab, and directed so as to discharge a shower directly over said entrance and for a distance outward therefrom, according to the adjustment of the nozzles, as hereinafter described. The pipe 1 may have additional branches 5 5, leading up at the forward end of the cab to nozzles 6 6, located, respectively, in position to discharge jets along the running-boards and over the pilot. Valves for controlling the several pipes and the discharge through their respective nozzles are placed in such position that they may be reached and operated by the engineer by his foot without moving from any position which he might occupy while controlling the locomotive, but in such position as to cause no danger of accidental operation. The valves 7 7, 8 8, and 9 9 for controlling the three pipes from either side of the cab may be located, as seen in the drawings, so that the levers 7 8 9 for controlling them respectively project in position to be easily reached by the foot of the engineer or fireman occupying his usual station behind the look-out window, all three levers being within the range of the foot at the same time, so that all may be operated by the action, but the rear lever being the shortest, the next in front being a little longer, and theforward one being the longest, so that either can be selected and operated alone by the foot. The levers are preferably quite near the floor and guarded by the overhang ing lip 10 of the usual seat, so that they are not likely to be struck by accident, and yet in position such that they may be reached without any movement of the foot which will require a movement of the body which would be obvious to the intruder who may be attempting to intimidate the engineer, and for this latter purpose the range of movement of all the levers is short. The engineer or fireman threatened with an attack can press all the levers at once and practically surround the locomotive at all points of action with a shower of hot water, or-if the situation requires only discharge from the nozzles 4 4, as in case the intruders are seeking to enter the cab at either side, the engineer will depress the lever '7 only far enough to open the valve controlling these nozzles. If, on the other hand, the approach is being made from the rear eitherover the tender or by intruders who may have obtained or are attempting to obtain lodgment on the platform of the car A, the engineer may depress the lever 8 only or he may depress both levers to the full extent, and thus at the same time protect the cab-entrance and drive the intruders from the tender or car. If an attackshould be made from the front by climbing over the pilot and threatening the engineer from the forward end, he can throw a jet of hot Water in proper direction from nozzle 6 by use of the'lever 9 either with or without simultaneously operating the levers 7 and 8.

I do not limit myself to the particular arrangements of pipes, nozzles, or valves herein shown, as they are only intended to be suggestive of the principle and general method of construction which characterize my invention. Any other position at which it may be found desirable to locate the nozzles in order to protect the locomotive from intrusion or to enable the engineer or fireman to repel attack from intrusion may be reached by pipes controlled by valves located in' positions analogous to those suggested for the nozzles shown. The preferred form of dischargenozzle for the purpose is what may be known as a spoon nozzle, and such nozzle is illustrated in the drawings, the discharge being made against the concave face of a spoonshaped deflector and spreader 12, the entire charge.

I I claim- 1. In combination with a locomotive, a pipe:

system connected with the boiler and having nozzles adapted to discharge along lines of approach to the cab at both sides; two means for controlling discharge through the nozzles at both sides, one of said means being located at one attendants station, and the other, at the other attendants station in the cab, whereby from either station the nozzles at both sides may be operated.

2. In combination with a locomotive, a pipe system connected with the boiler and having nozzles adapted to discharge along lines of approach to the cab at both sides; two valves, each independent of the other, controlling the discharge through nozzles at both sides, and means for operating one of said valves located in position for operation by the foot of the attendant at the engineers station, and means for operating the other valve located in like position at the firemans station in the cab.

3. In combination with a locomotive, a pipe system having two connections with the boiler, and having nozzles adapted to discharge along lines of approach to the cab at both sides; a valve in said pipe system between each of the boiler connections and the nozzles, and means for operating either of said valves independently of the other.

t. In combination with a locomotive, a pipe system connected at both ends with theboiler and having nozzles adapted to discharge along lines of approach to the cab, valves controlling said pipes and means for operating the same located in positions to be operated by the foot from the engineers or firemans stations in the cab.

In testimony whereof I have hereunto set my hand, at Chicago, Illinois, in the presence of two witnesses, this 11th day of September, 1902.

GIDEON A. COPP. In presence of (Irma S. BURTON, FREDK. G. FISCHER.
