Application mea Aprii 24,1903.

To aZZ'whow/t it may concern:

Beit known that I, FRED A. DALEY, a citizen of the United States, residing at Chicago, 1 in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Stoking Mechanism, of which the followingis a full, clear, concise, and eX- act description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to stoking mechanism, and has forits Object improved construction thereof and improved disposition of the parts mism is utilized.

My invention is particularly adapted to soder at the Outside thereof.

Heretofore it has been the practice to place the retort at the inside of the boiler-chamber, so that the front flanged face thereof was disposed to the rear` of the furnace or boiler front. The ram-case, which was provided with a flange at its end, projected into an opening in the boiler-front to be bolted or otherwise fastened to the retort, the outside face of the boiler-front and the outside face of the ram-case fiange being Hush by such disposition. v

When it was desired to inspect the interior of the ram-case, which usually consisted yof a lower and an upper removable half, it was necessary after withdrawing the bolts which fastened the ram-case to the retort to move backward both the cylinder and the ram-case in order to remove the top portion of the ramcase, which in tsA normal position-projected Within the boiler-front.

My invention provides means for removing the top portion of the ram-case for the purpose of inspection without changing the position of the lower part of the ram-case, and to this end I arrange the retort within the boiler, so that the front face thereof projects into the opening in the boiler-front and iush Serial No. 155142. (No model.)

with the outside face of the boiler-front. The top portion of the ram-case may now be bolted in the usual manner to the retort and no impediment is oered to its ready removal from the lower portion of the ram-case. The retort has rearwardly and upwardly extending side walls, the faces of the front ends thereof being disposed to aline with the inner face of the boiler-front, which boiler-front extends downward between said faces and the upper portion of the flange on the removable ramcase section. As the removable section is bolted to the retort, the boiler-frontis clamped and securelyheld to prevent warping thereof as it is heated.

I shall explain my invention more fully by reference to the accompanying drawings, in which- Figure 1 is a sectional view illustrating the application of my invention to a stoker of the underfeed type. Fig. 2 is a perspective view showing the disposition and manner of assembling the ram-case parts and the retort with respect to the boiler-front. Fig. 3 is a detailed view showing the construction of the ram-case and retort at the point of junction. Fig. 4 is an end view of the retort. Fig. 5 is a side View of the forward end of the retort.

Like characters of reference indicate like parts throughout the figures.

yA boiler 1 is suitably mounted upon a setting 2 and is adapted to receive heat generated in the tire-chamber 3. A retort 4 is disposed within the boiler-chamber and is adapt- ,ed to receive fuel discharged therein from a ram-case 5, supplied from a hopper 6. Apiston 7 is caused to Oscillate in a Huid-cylinder 8 in a manner well known to those skilled in the art to reciprocate a plunger 9 within the Vposed to the rear of the boilerfront.

bolt-holes 19, whereby the two halves may be securely bolted together. The lower portion of the ramcase is provided with a down'- wardly-extending ange 20, adapted to be bolted against the lower portion of the front face of the retort by means of bolts 21. The upper portion of vthe ramcase is provided with an upwardly-extending ange 22, adapted to be secured to the upper part of the front face of the retort.

The retort has rearwardly-extending side walls 23said walls also extending upwardly, the front faces 24f'thereofrbeing adjacent to the inside face of the boiler-front. The flange 2 of the upper portion 16 of the ram-case extends a' slight distance beyond the top edge of the retort-ange, disposed within the openingr in the boiler-front, and asthe upper portion of the ra1n-case is bolted into position the boiler-front is clamped between the upper portion of the liange thereof and the upwardly-extending side walls of the retort dis- As the boiler-front becomes heated warping thereof is prevented.

It will thus be readly seen that the ramcase is very readily accessible for inspection and repairs without moving the entire ramcase structure and the fluid-cylinder, as has heretofore been necessary, in order to gainl access to the ram-chamber.

Although I have described my invention as applied to stokers of the underfeed type, it is applicable to stokers of other types, and

changes in the structure thereof may be read.-
