APPARATUS FOR FEEDING BAGASSE TO FURNSACESI SPECIFICATION forming part of Letters Patent No. 739,161, dated September 15, 1903.

Application filed .Tuly 25,1902. Serial No. 116,984. (No model.) Y

T0 a/ZZ whom. it may aon/cerro:

Be it known that I, JAMES FISHER, a citizen of the United States, residing at NewOr.- leans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Apparatus'for Feeding Bagasse to Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatus for feeding bagasse, sawdust, or other fine fuel to furnaces. It is especially intended to provide a suitable apparatus for distributing bagasse from one source to a number of furnaces.

The invention also relates to certain improvements on my patents Nos. 564,918, granted July 28, 1896, and 591,752, granted October 12, 1897.

Referenceishadto the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views. l

Figure 1 is a plan View showing the apparatus as arranged for distributing the bagasse coming from a single chute to fourfurnaces, parts being broken away. Fig. 2 is a front elevation of the device shown in Fig. 1. Fig. 3 is a cross-section through one of the feedchutes, the furnace being shown in elevation. Fig. 4 is a plan view of a modification, showing the apparatus arranged for feeding two furnaces only; and-Fig. 5 is a front elevation of the device shown in Fig. 4. Fig. 6 repre` endless carrier C runs, provided with slats c,

which push the bagasse along the bottom of the trough. This carrier O isdriven in any convenient way, as by means of the pulleyD and belt D'. Openings B0 are provided in the bottom of the trough B above the chutes F, which openings are wholly or partly closed by the gates E, which are cut away at an angle, as indicated at e. Suitable handles e may be provided for adjusting the gates. will be seen that these gates either wholly or partially close the openings B0, and by moving the gates in or out the portion of the bagasse y that falls through the respective openings is varied at will. Thus, for instance, if the first gate be pulled all the Way out all of the bagasse would go to the first furnace or by closing all the gates but the last all of the bagasse would go to the last fur- In practice it would be desirable to divide the bagasse up between the several furnaces in use, which is done by adjusting the gates, as indicated in Fig. 1 or in Fig. 4. Thus it will beseen that any one or more furnaces can be cut off and the bagasse distributed to the other furnaces. This is important to accomplish, as it is desirable not to stop the mill from grinding; but at the same time the boilers and furnaces must more or less frequently be cleaned out or repaired. The bottom of the chute F is preferably hinged, as at f', and secured at f2 to the bottom of the trough B, so that when it is desired thes'e bottoms may be lowered and the bagasse may be allowed to drop to the ground or into a wagon provided for the purpose. A

The bagasse is delivered from the chute F to the feed-box H, which is controlled by a door K, hinged, as at 7o, and having a. weighted arm lo projecting through the slot lo". (See Fig. 3.) The weight of the bagasse will press this door open, but it will automatically close when the bagasse has passed through, thus preventing theinflux of cold air into the upper part of the furnace. The bottom of the feed-box is closed by a door H', hinged, as at h', and locked, as at h2. This door may be swung downward, as indicated in dotted lines, when it is desired to obtain access to .the feed-box for purposes of cleaning out or repairing. The weights on the rod 7c' are adjustable back and forth, so thatv they [may yield to dierent weights of bagasse pressing against the doors K. It follows, therefore, that by adjusting one of the openings Bo and the weight on the corresponding rod lo the IOO openings.

bagasse may be fed slower to some furnaces than to others, which is often desirable.

M represents a toothed roller having teeth m, -which roller is driven at a high speed by means of pulleys M and throws the bagasse through the opening O into the furnace.

P represents a boiler; but I do not mean to limit the invention to any particular kind of furnace or any particular kind of boiler.

In the modification shown in Fig. 4 the carrier A from the mill runs parallel and above the trough B and dumps the bagasse into the said trough without the necessity of a chute A or of cutting away the said chute at an angle, as shown in Figs. l and 2.

In the modification shown in Fig. 6 instead of having adjustable gates ont away at an angle the bottom of the trough is cnt away at an angle, as indicated at b', b2, and b3. In this case the bagasse will be fed to three feedchutes; but the bottom of the trough could be cnt so as to feed to one, two, or more. In this case, however, it would be impracticable to adjust the feed or to cnt olf the feed from one or more boilers or furnaces Without providing some means for closing the several I therefore prefer to use the gates cut away at an angle. This cut-away construction of the gates and of the openings I will for Convenience in drawing the claim call the anglegates and the angle-openings, respectively. Wind-guards W may be provided, as shown in Fig. 3, to prevent the wind from blowing away any of the bagasse as it falls into the chute. Thus it will be seen that I provide an apparatus by means of which the bagasse is uniformly distributed over lthe floor of the trough and is automatically delivered from that trough in regulated proportions to a plurality of furnaces. By having these angled openings the bagasse is uniformly distributed in the various chutes, and thus is more evenly fed into the furnace.

It will be obvious that various modifications in the herein-described apparatus might be made which could be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In an apparatus for feeding bagasse to furnaces,the combination of furnaces,a weighted door for each furnace, a rod attached to each door and a weight adjustably secured on said rod, with a chute delivering into each furnace, a trough provided with openings located one above each chute, and means for adjusting the size of the opening above each chute, substantially as described.

In testimony whereof I alix my signature in presence of two witnesses.

JAMES FISHER.
