- GEORGE A. SCHMIDT a subject of the German Emperor, residing in the city of Quedlinburg, Republic of Saxony, Kingdom of Prussia, Germany, now temporarily residing at St. Paul, in the county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Safety Devices on Trains, of which the following is a speciiication.
- Our invention relates to the use of steam and hot water taken from the locomotiveboiler at certain specified points upon the engine and its distribution and use at certain other specified places upon the locomotive, tender, and cars for the purpose of preventing attack and robbery of the train and its contents when in use.
- a further object is to provide a very simple and effective arrangement and location of valves and pipes for the distribution of water from the locomotive-boiler to the usual entrances of the cab of the locomotive and tender and to the doors, entrances, and platforms of any or all cars of the train.
- a further object is to provide nozzles or mouthpieces or openings in the various pipes of special design calculated to distribute the steam and hot water in the best manner possible to prevent entrance to the engine or train by robbers, highwaymen, or other persons.
- Figure 1 is a vertical section of the rear portion of a locomotive and cab and a portion of the tender as usually arranged in a modern locomotive.
- Fig. 2 is a horizontal sectional View of the locomotive on the line af a' of Fig'. l.
- Fig. 3 is a vertical longitudinal section on the line l1/ z/ of Fig. Q.
- Figs. Li, 5, 6, and 7 are end views of the pipe-nozzles.
- Figs. 8, 9, 10, and 11 are longitudinal sectional views of said nozzles, respectively.
- Fig. 12 is a detail of the T device provided in one of the branch pipes.
- Fig. 13 is a section on the line .e s of Fig. 12.
- the pipe 6 extends toward the center over the top of the boiler, where a branch pipe 1l at a T-joint 1Q carries a portion of the water toward the back of the cab, while pipe 6 passes over to the other side of the boiler into a joint 8 and pipes 9 and 10, corresponding to those heretofore described with reference to the other side of the cab.
- a nozzle 13 (see Fig. 9,) which is so constructed that the stream of water will spread out into a Y shape over the tender. A further description of this nozzle appears below.
- a nozzle 13 At 14 in pipe 10 is an opening' in the bottom of the pipe over the steps, as shown in Fig. 10, which is further described below.
- At 15 in lieu of slot 14 we may use a plain T-joint where 1() branches down into 16.
- 16 has a slot 17 in its outer face, as shown in Figs. 12 and 13. This is further described below.
- a nozzle 18 of the shape and design shown in Fig. 11,'having iaring sides and a slot 19 in its bottom At the end of the pipe 9 we prefer to provide a nozzle 18 of the shape and design shown in Fig. 11,'having iaring sides and a slot 19 in its bottom. A further description appears below.
- Pipe 11 terminates in the straight nozzle 20, as illustrated in Fig. 8.
- a slot 9.1 of suitable size to allow the best distribution of steam and hot water over the front, middle, and rear of the tender.
- the pipe 11 is a collar 2.2, adapted to slide over the slot 21 to concentrate the entire force of the water into a compact stream of great force. by means of which it may be moved back and forth over the pipe 11 with a fire hook or shovel. A detailed description follows below of this portion of the steam apparatus.
- Pipe 9 has the mouthpiece 18, as shown in Fig. 11. As illustrated in the ligure, we prefer to take a round pipeand bend down the top in the manner shown such that the angle of bending shall be live degrees or thereabout, depending on the length of the boiler. We prefer to have a slot 19 in the bottom of this pipe of a length equal to that of the bend in the upper part of the perimeter of the pipesay four inches. Then the force of the steam will be divided into three components, the downward component being equal to the tangent Aof live degrees and the other two spreading out in a Y shape forward. This vertical component will force a certain portion of the steam and hot water downward almost vertically, so as to cover the footboard up to the door, or nearly so.
- the bend in the center of the top of this pipe also serves in a measure to divide the main horizontal stream into a Y shape.
- the sides of the Y form an angle of about ten degrees with each other, in this manner covering all possible means of entry to the cab by the footboard, because, first, the slot covers the lower part of this space in front of the cab With a vertical fan-shaped stream almost up to the door; second, the right-hand arm of the Y will throw the Water out at a broad enough angle to preclude the chance of a man leaning far out as he came toward the cab having his feet on the board and holding to the side hand-rail with a hook which might be slid along the rail until he was so close the water would not reach him.
- the other arm of the Y forces the water to the side of the boiler, where it will strike with great force and drench the whole top of the boiler, and much of it Will rebound farther toward the front of the locomotive.
- the central part of the stream having great force will be carried straight to the front, covering the whole side footboard within the range of the steam so effectually that no one might live on it, absolutely preventing entrance to the cab from ahead.
- Pipe 10 has a nozzle 13, substantially as shown in Fig. 9 of the drawings.
- the top and bottom of this pipe are bent in toward the axis of the pipe until the slope of the top and of the bottom for a distance of about four inches is about five degrees each with the axis of the pipe.
- This depression at both top and bottom of the pipe has the effect of spreading' the stream out in fan shape, and thus covers the tender more effectively than a straight pipe would .do.
- the collar has a handle 22',-
- a slotor T-joint in pipe 10 over the steps.
- the slot 14 is located in the bottom of the pipe 10 and has a greater width at the center than at the ends; hence will throw a Wider stream out, over, and around the steps than a single straight slot would do.
- this form of slot does not give satisfaction, we prefer to substitute for it a T-joint 15 and an outstanding leg 16, turned down over the steps. The angle with the vertical which the leg makes will depend on the type of engine.
- the combination with a main steam-supply pipe, of branch pipes leading to the sides of the cab and having slots in their under sides of varying width arranged to discharge steam and hot water over IIO and beyond the steps to prevent entrance to the cab, and means for regulating the How of steam through said pipes.

SAFETY DEVICE ON TRAINS.
SPECIFICATION forming part of Letters Patent No. 766,631, dated August 2, 1904.
Application filed March 13, 1903. Serial No. 147,679. (No model.)
T0 all whom, it 'muy concern:
Be it known that we, JULIUs L. KUHL, a citi- Zen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, and GEORGE A. SCHMIDT, a subject of the German Emperor, residing in the city of Quedlinburg, Province of Saxony, Kingdom of Prussia, Germany, now temporarily residing at St. Paul, in the county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Safety Devices on Trains, of which the following is a speciiication.
Our invention relates to the use of steam and hot water taken from the locomotiveboiler at certain specified points upon the engine and its distribution and use at certain other specified places upon the locomotive, tender, and cars for the purpose of preventing attack and robbery of the train and its contents when in use.
A further object is to provide a very simple and effective arrangement and location of valves and pipes for the distribution of water from the locomotive-boiler to the usual entrances of the cab of the locomotive and tender and to the doors, entrances, and platforms of any or all cars of the train.
A further object is to provide nozzles or mouthpieces or openings in the various pipes of special design calculated to distribute the steam and hot water in the best manner possible to prevent entrance to the engine or train by robbers, highwaymen, or other persons.
Other objects of the invention will appear from the following' detailed description.
In the accompanying drawings, forming part of this specification, Figure 1 is a vertical section of the rear portion of a locomotive and cab and a portion of the tender as usually arranged in amodern locomotive. Fig. 2 is a horizontal sectional View of the locomotive on the line af a' of Fig'. l. Fig. 3 is a vertical longitudinal section on the line l1/ z/ of Fig. Q. Figs. Li, 5, 6, and 7 are end views of the pipe-nozzles. Figs. 8, 9, 10, and 11 are longitudinal sectional views of said nozzles, respectively. Fig. 12 is a detail of the T device provided in one of the branch pipes. Fig. 13 is a section on the line .e s of Fig. 12.
Steam and hot water are taken from the locomotive-boiler at any convenient place on either side by a pipe passing through the oneway valve 1, operated by the lever 2 from either side. IVhen the lever is in a horizontal position, the steam is shut off; but when it is revolved through an angle of ninety degrees in the direction of the arrow by a push or pull of the hand or foot the steam and hot water will be forced through the pipe 3 up to a T-joint 4, where the water is divided into pipes 6 and 7, the former leading' over the top of the boiler and the latter to the side of the cab. The pipe 7 at 8 forms a T-joint with the pipes 9 and 10, dividing the pressure to the front and rear of the eab, respectively. The pipe 6 extends toward the center over the top of the boiler, where a branch pipe 1l at a T-joint 1Q carries a portion of the water toward the back of the cab, while pipe 6 passes over to the other side of the boiler into a joint 8 and pipes 9 and 10, corresponding to those heretofore described with reference to the other side of the cab.
At the end of the pipe 10 is a nozzle 13, (see Fig. 9,) which is so constructed that the stream of water will spread out into a Y shape over the tender. A further description of this nozzle appears below. At 14 in pipe 10 is an opening' in the bottom of the pipe over the steps, as shown in Fig. 10, which is further described below. At 15 in lieu of slot 14 we may use a plain T-joint where 1() branches down into 16. 16 has a slot 17 in its outer face, as shown in Figs. 12 and 13. This is further described below. At the end of the pipe 9 we prefer to provide a nozzle 18 of the shape and design shown in Fig. 11,'having iaring sides and a slot 19 in its bottom. A further description appears below. Pipe 11 terminates in the straight nozzle 20, as illustrated in Fig. 8. In its bottom is a slot 9.1 of suitable size to allow the best distribution of steam and hot water over the front, middle, and rear of the tender. Ou the pipe 11 is a collar 2.2, adapted to slide over the slot 21 to concentrate the entire force of the water into a compact stream of great force. by means of which it may be moved back and forth over the pipe 11 with a lire hook or shovel. A detailed description follows below of this portion of the steam apparatus.
prefer to vary this angle to suit the dimensions of the various tenders. Also we prefer to shorten or lengthen the distance for which,V
the pipe is bent, for if the bend is short it will tend to give a wider angle of throw to the water, and conversely.
We show in Figs. 10, 12, and 13 details for a slotor T-joint in pipe 10 over the steps. The slot 14 is located in the bottom of the pipe 10 and has a greater width at the center than at the ends; hence will throw a Wider stream out, over, and around the steps than a single straight slot would do. Where this form of slot does not give satisfaction, we prefer to substitute for it a T-joint 15 and an outstanding leg 16, turned down over the steps. The angle with the vertical which the leg makes will depend on the type of engine. Further, we provide a slot 17 in the outer portion of the leg 16, which extends upward from the end far enough to throw a part of the stream out beyond the steps to prevent close approach to the locomotive.
In pipe 11 we provide a straight nozzle 20 to cover the center of the cab most effectively. The nozzle 2O will have in its bottom a straight slot 21 about six inches long, which will allow a part of the water to come down onto the front part of the coal, while the main portion is forced straight over the tender. By sliding the collar 22 along on the pipe the entire force may be concentrated back'over the tender. This collar may be prevented from sliding oif the pipe by a set-screw 23 at the end of the nozzle 20.
`We claim as our invention- 1. In safety devices for trains, the combination of a main'steam-supply pipe branching to IOO the front doors over the side footboards for the purpose of preventing entrance to the cab from the front with nozzles at the end of said pipe having a slot in its bottom for a distance from the end and its upper part bent down toward the center at an angle of five degrees with the axis of the pipe, with means for varying the pressure of water flowing out of these pipes.
2. In safety devices for trains, the combination of a main supply-pipe leading from the locomotive-boiler with branches leading along the sides of the cab to the back where steam and hot water are ejected. at high pressure over the tender for the purpose of preventing entrance to the cab; the side pipes having nozzles in which the top and bottom of the pipe are each bent in toward-the center of the pipe at an angle of five degrees along the center of the pipe for the purpose of spreading the contents of the pipe through awide angle over the tender.
3. In asafety device for trains, the combination, with a main steam-supply pipe, of branch pipes leading to the sides of the cab and having slots in their under sides of varying width arranged to discharge steam and hot water over IIO and beyond the steps to prevent entrance to the cab, and means for regulating the How of steam through said pipes.
I. In safety devices for trains, the combination of a pipe from the locomotive-boiler under the rooil to the back of the cab for forcing water and steam out upon and over the tender and in the bottom of this pipe for a short distance from the end, a slot to allow the Water and steam to come down nearly vertically into thc fore part or' the tender with a sliding adjustable collar to cover the slot forthe purpose of concentrating the stream of Water when desired to prevent entrance to the cab from the rear over the tender.
