LOCOMOTIVE.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed May 26, 1909. Serial No. 498,578.

` To all whom it may concern:

Be it known 'that I, JOI-IN F. BECK, a citizen of the United States, residing at Grand Rapids, Michigan, have invented certain new and useful Improvements in Locomotives, of which the following is a specification.

This invention relates to improvements in locomotives.

My improvements relate particularly to the smoke boX and front of locomotives, although it may be adapted for use, and certain features of it are of advantage for use in other structures.

The main objects of this invention are: First, to provide in a locomotive, an improved smoke box and front so constructed as to effectively withstand the effect of the heat from within and the cold from without to which it is subjected in use. Second, to provide in a structure of the class described, a smoke box in which a large per cent. of the heat units of the products of combustion passing therethrough are utilized. Third, to provide in a structure of the class described, an improved smoke boX and front in which the expansion and contraction and warping of the front due to the extremes of heat and cold are obviated.

Further objects, and objects relating to structural details, will definitely I appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification,

The structure described constitutes one effective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined `and pointed out in the claims. y

A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this invention, in which:

Figure 1 is a side elevation of a locomotive and its tender, embodying the features of my invention.' Fig. 2 is an enlarged detail front elevation thereof.` Fig. 3 is an enlarged detail longitudinal section taken on a line corresponding to line 33 of Fig. 4, through the smoke boX thereof.` Fig.` 4 is a detail vertical section taken on a line corresponding to the broken line of Fig. 3,

looking in the direction of the little arrows designated by the numerals 4 4. Fig. 5 is an enlarged vertical section taken on the broken line of Fig. 3, looking in the direction of the arrows designated by the numerals 5-5, which is opposite to that of Fig. 4. Fig. G is an enlarged detail section through one of the front door clamps taken on a line corresponding to line 6-6 of Fig. 2. Fig. 7 isa detail section taken on a line corresponding to line 7 7 of Fig. 6. Fig. 8 is an enlarged detail elevation of one of the hinges for the front door. Fig. 9 is an enlarged detail section taken on a line corresponding to line 9-9 of Fig. 8. Fig. 10 is a detail section taken on a line corresponding to line 10-10 of Fig. 8.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the" sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the locomotive, which is designated generally in the drawing` by the numeral 1, is provided with a smoke boX 2 at its forward end. The furnace fines 3 are arranged to deliver to the smoke box, as is indicated in the drawing, the details only of the fines being shown.` The steam pipe 4, which is also shown in detail, is arranged to deliver to the steam chests through the steam pipes 5. The cylinder saddle 6 is arranged beneath the smokeboX, as is the common practice.

The smoke sta-ck is preferably provided with a downwardly projecting petticoat or draft flue 8, the lower end of which is bellshaped or flared outwardly. Below this draft flue or pipe 8 is the nozzle stand 9, de-` tails of which are not here illustrated.

The deflector plate 10 is arranged at the rear of the draft flue 8 and projects downwardly and forwardly beneath the same, the nozzle 11 being arranged through the de- {iector plate, as is indicated. From the forward end of the deflector plate to the top of the arch chamber and in front of the draft pipe, I arrange a screen 12. This screen is preferably provided with a door or man-hole `opening 13, which is closed by a screen 14. This screen is, in the structure illustrated, secured by the means of staples 15 and hooks 16, so `that it can be easily attached or detached. j j The smoke box front is made up of an outer wall 17 and an inner wall 18 to form a water chamber 19 between the same. This water chamber is connected tothe supply tank of the locomotive, which is designated generally by the numeral 20, by a suitable circulation connection consisting of a pipe 21, which is connected to the tank and to the chamber 19 in the smoke box front at the bottom thereof, and a return pipe 22 which is connected to the tank and the chamber in the smoke box front at the top thereof, see Fig. 2.

In the pipe 21 is a circulation pump 23,

which is indicated in conventional form, see Fig. 1. By means of this pump and circulation connection, the water is circulated from the tender tank through the water chamber in the front.

The frontdoor is formed of an outer wall 24 and an inner wall 25 to provide a water chamber 26 therein. This chamber 26 in the door is connected to the chamber 19 in front by suitable passages, preferably through the hinges and securing clamps for the door. The details of one of the securing clamps, which is hollow, are illustrated in Figs. 6 and 7, while the details of one of the hinges, which is also hollow, are illustrated in Figs. 8, 9 and 10. The securing clamps for the door preferably consist of the socket members 27, which are threaded into the outer walls ofthe front and door, and the yokeshaped member 28, the ends of which are adapted to fit into the sockets. The member 28 is clamped in place by the clamping screw 29, see Fig. 6. These clamping means are provided with water passages so that the water chambers in the front and door -are connected.

The hinge preferably consists of the knuckle member 30 and the pintle member 31, the knuckle member being tapped into the outer wall ofthe front, while the pintle member is secured to the door and provided with a passage opening into the water chamber of the door. The passages in the pintle and knuckle members are arranged to register when the door is closed, but preferably brought out of register when the ldoor is opened, so that they serve as cut-off valves.

A plurality of clamps are preferably provided, spaced about the door so as to Ainsure a circulation through the water chamber of the door. To add `to, t-he heating capacity, I provide the smoke box front and door with a plurality of U-shaped heating pipes 32. These pipes are mounted on the inner walls of the front and door to project into lthe Vsmoke box chamber. rlhese U-shaped heating pipes are arranged one leg above the other so that circulation therein is insured. The products of combustion passing through the smoke box are deflected by the vdelector plate against the inner walls of the 'smoke box front and door and across these heating pfipes so that the structures serve as a very e ective means of taking up the heat from the products of combustion, which is carried back tothe suppl tank through the circulation connections escribed. A very effective and even circulation is secured through the water chamber of the front and door, so that a comparatively even temperature is maintained in the front, thereby preventing its being injured by excessive heat, or by excessive heat within and excessive cold without, which injuries result from the conditions where adequate provision is not made to overcome the defect.

The loops of pipe 32 are of different lengths, being longer toward the bottom, which insures larger exposure of the surface. An important action of these loops of pipe is that they serve to break up large cinders and assist in reducing the size of the same so that they pass readily through the screen and out, and, at the same time, owing to the fact that the pipes are filled with comparatively cool water, the heat of the cinders is reduced so that there is less likelihood of damage by fire along the right of way.

I have illustrated and described my improvements embodied in a structure which I consider highly satisfactory. Various of the parts are shown only in conventional form, and the particular details of construction which I have illust-rated can be very greatly varied without departing from the essence of my invention. I desire to be understood as claiming the same in detail in the form illustrated and described, as well as broadly.

I-Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent is:
