JAMES MILLHOLLAND, OF READING, PENNSYLVANIA.
Specication forming part of Letters Patent No. 41,316, dated January 19, 1864.
To all whom it may concern.-
Beit known that I, JAMES MILLHOLLAND, of Reading, Berks county, Pennsylvania, have invented an Improvement in Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention consists in the arrangement, substantially as described hereinafter, ot' a tire-box with its grate depressed at one or both ends in respect to the frame-work of a locomotive-engine, whereby I am enabled to increase the grate-surface and obtain the desired depth of tire-box Without lengthening the same or elevating1 the boiler, and without resorting to elaborate and expensive frame- 'work to place the lire-box directly over the frames of the locomotives instead of between the frames as usual, thereby increasing the width of the tire-box, and the grate-surface of the same.
In order to enable others skilled in the art to make and use my invention, I will now pro- .ceed to describe the-construction of the same and the results attained.
0n reference to the accompanying drawings, which form a part of this specification, Figure lis a vert-ical section of a part of a locomotiveboiler with a portion of the frame; and Fig. 2 is a transverse vertical section, on the line 1 2, Fig. l.
A represents the tire-box of a coal-burning locomotive-boiler, t being the top of the box, b b the opposite sides of the same, d the front tubeplate, c the front of the box, f the opening for the admission of fuel, and 7L the grate-bars, which are similar to those for which Letters Fatent were granted to me on the 16th of April, 1861.
Although I have shown the boiler as provided With my patent grate-bars, it should be understood that my present invention'is not dependent on or in any way connected with any particular system of grate-bars.
B represents thatportion of the boiler which surrounds the re-box, there being the usual water-space between the inner and the outer plating of the lire-box.
D and D represent portions of the frame of the locomotive, and consist of simple straight bars, above which is secured the hre-box of the boiler, as seen in Fig. 2, the interior width of the fire-box being equal or about equal to the distance between the two frames. Either the front and rear of the re-box, or both ends of the same, may be carried downward below the sides of the box forming the projection x, Fig. 2, the grate-bars being secured in any convenient manner, so that the grate itself, or the greater portion ofthe same, is lower than the top of the frame.
It is well known to those familiar with the construction of locomotives that the boiler should be as low down as possible, and that every effort should be made to obtain a tirebox ofthe greatest width, so that the length may be within reasonable bounds, while a given depth is necessary below the tubes for an appropriate quantity and depth of fuel.
In most instances the fire-box is depressed between the frames of the locomotive, the result ot' which is the necessity of making the re-box very narrow, especially when the locomotive is made for traversing a narrow-gage track. In this case, therefore, while the boiler may be as low as desired, it becomes necessary to make the contracted tire-box ot' inordinate length in order to obtain the. proper amount of grate-bar surface.
In some instances a comparatively wide and depressed tire-box is obtained by making the 'framework of a fornito suit the box, but this can only be done by resorting to frames demandn g the most expensive and complex forged work.
lt will be observed that the frames D and D are simple straight bars, and that the firebox sides are situated directly over these frames, while the grate is depressed below them.
By this simple arrangement the tire-box is made of proper depth, its width and the area ot the grate are increased without elevating or lengthening the tire-box, and all costly forged frames are avoided.
I claim as my invention and desire to secure by Letters Patent- The arrangement, substantially as described, ofthe tire-box, with its grate depressed at one or both ends in respect to the frame B of a locomotive-engine, for the purpose specified.
Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses..
JAMES MILLHOLLAND.
