FEED DEVICE FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 530,998, dated December 18, 1894.

Application filed August 18, 1894.

To all whom it may concern:

Be it known that I, LAZER LAZERUS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in a Combined Blast and Fuel-Feed Device'for Locomotives, of which the following'is a specification.

The object of my said invention is to provide a means, whereby fuel may be either partly or wholly supplied to a locomotive, and

the combustion of such fuel may be accelerated. f

A locomotive and tender provided with my said invention will be'first fully described and the novel features thereof then particularly Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a view of a tender and a said invention, the side of the locomotive be ing broken away to show the apparatus more on the dotted line 2 2; Fig. 8, an end elevation of the tender, as seen from the dotted line 3 3; Fig. 4., a detail View of the upper end of the escape pipe and safety valve, and Fig. 5 a detail ofthe union'between the hydrocarbon and air pipes.

In said drawings the portions marked A represent the locomotive boilers, including the fire-box or combustion chamber; B, the tender; 0, the steam cylinders of the air pumps; D, the air cylinders of said air pumps; E, a steam-pipe leading from the locomotive boiler to the steam cylinder 0; F, a pipe leading from the compressed air reservoir to the locomotive fire-box; G,a gage attachedthereto; H, an escape pipe, and I a hydrocarbon receptacle. V I

The locomotive'A is or may be of a usual or any desired construction, and has the usual which a locomotive-is usually supplied.

The tender B isof'a different construction the drawings, and is provided with an air chamber B which is adapted to receive and hold compressed air, and this chamber is usu- Serial No. 520,701- (No model.)

' ally and preferably of considerable capacity and ispreferably located at the bottom of the tender below the fuel space in front of the fire-box of the locomotive.

l The steam cylinders C may be of a usual construction for pumping purposes, and are provided with steam from the locomotive boiler through the pipes E. The piston O is preferably bifurcated, and each branch, 0', leads to and operates in, one of the two attached air pumping cylinders D, as shown. There-are preferably two of these steam cylinders, 0ne on each side of the tender, as shown.

The air-pumping cylinders D are preferably four in number, two to each steam cylinder, and are operated in a usual and well known manner from said steam cylinders.

Pipes D lead therefrom and discharge into the air reservoir B.

The pipes E are ordinary steam pipes, and preferably leadfrom the steam dome on the locomotive boiler to the steam cylinders 0. As they pass between two moving parts they are provided with the usual flexible couplings common to" such constructions, and are also provided with suitable valves, as e, whereby the stream may be turned on and off at pleasure.

The pipe F leads from the air reservoir B" directly to the fire-box A, where it has a nozzle F pointing into said fire-box. A valve F is provided to turn on or off and regulate the blast of air. A branch pipe F leads up to the gage G, and thislatter serves to indicate the voir, and when the pressure exceeds what has been predetermined, the springs will yield and a portion of the air escape.

The hydrocarbon receptacle I is a tank .or reservoir of any convenientshape and size secured in or upon the tender, and a pipe 1' leads therefrom down to and connects with the pipe F in such a manner that hydrocarbon from said receptacle may mingle with theinto the fire-box and acts both as a blast and as an addition to the fuel, assisting materially in both particulars in making a hot fire, and thus generating the steam. The air reservoir or tank B is always kept charged with a suificient quantity of air so that this apparatus may be put in use at once when desired, without waiting for the generation of steam after a fire is first kindled, although, as is well known, a small amount of steam is generally kept up in a locomotive, and, therefore, the air can ordinarily be pumped whenever desired.

My said invention is not only applicable where, as has so far been described, ordinary fuel is used, but it is of especial value where a hydrocarbon fuel is exclusively used, in which case a hydrocarbon tank or reservoir would occupy a large portion of the space in the tender, or substantially the same space as is usually provided for the fuel; and the small hydrocarbon tank could then be charged from time to time from the larger tank, or, by appropriate attachments, the fuel could be conducted directly from such larger tank to the air pipe.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, with a locomotive and its tender, of an air pumping apparatus secured to said tender, an air reservoir or tank within said tender with which said pumping apparatus connects, a steam-pipe leading from the locomotive to said pumping apparatus, to furnish steam for operating same, and an air pipe leading from said air reservoir or tank to the fire-box ofthe locomotive, the section between the tender and locomotive being provided with a suitable coupling said several parts being arranged and operating substantially as set forth.

2. The combination of a locomotive provided with the usual fire-box,a tender provided with an air reservoir or tank, an air pumping apparatus mounted upon said tender, a steam pipe leading from the locomotive tosaid pumping apparatus whereby it is operated, connections between the air cylinders and said. reservoir or tank, a pipe leading from said reservoir to the fire-box of said 10- comotive, and an escape pipe provided with a safety valveconnected to said reservoir or tank.

3. The combination of the locomotive A having the fire-box A, the tender B having air reservoir or tank B, the air-pumping apparatus consisting of steam cylinder 0 and air-pumping cylinders D D, a-bifurcated piston operating from said steam cylinder to said air-pumping cylinders, pipes D D from said air-pumping cylinders to said air reservoir or tank 13, a pipe F leading from said air reservoir to said fire-box where it is provided with anozzle F, a branch pipe F terminating in a gage G, a valve F ,\a steam pipeE leading from the locomotive to the steam cylinder 0 and provided with a valve e, and an escape pipe H having a cap l-I' secured thereto by bolts h and springs h, the whole being combined, arranged andoperating, substantially as shown and described and for the purposes set forth.

4. The combination of a locomotive, its tender, an air reservoir in said tender, an air pumping apparatus mounted on said tender and connected with said reservoir, a pipe leading from the locomotive tosaid pumping apparatus to supply steam for operating the same,

a pipe leading from said reservoir to the fire box of the locomotive with a suitable coupling in the section between the tender and locomotive, a hydro-carbon reservoir and a pipe leading from said hydro-carbon reservoir to said air. pipe with which it communicates by a suitable connection and suitable valves for controlling the How of hydro-carbon, air and steam through the difierent parts of said apparatus, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 10th day of August, A. D. 1894.
