APPARATUS FOR suP-Ptvme Puget-To STEAM-BOILERS- SPEGIF-IQATION forming part of Letters Patent No. 224,237, dated February- 3, 1880.

' Application filed July 8, 1879. Patented in England, August 21, 1877.

To all whom it may concern Be it known that I,'OHARLES SMITH, of Burnley, in the county of Lancaster, in that part of the United Kingdom called England} mechanic, have invented new and useful Improvements in Apparatus for Supplying Fuel to Steam-Boilers and other Furnaces, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.

To afiord a uniform intermittent supply of fuel to the stoker or to the furnacefrom' the feed-hopper, and direct the fuel thrown by the fans or other medium upon and over the fire,

according to this my invention, I employ a hopper or hoppers the bottom or lower partof which is in communication with a cylinder the upper and lower sides of which are provided with openings for the reception and exit of fuel. Within the cylinder is a roller, caused to rotate slowly by gear-wheelsor other driving apparatus. The periphery of the roller is, at intervals, recessed, forming receptacles, within which coal, as the receptacle comes under the,

hopper, is received. The continued rotation brings the receptacle over the exit-opening through the cylinder, by way of which the fuel passes outto the furnace or to the mechanical stoker, and so as each recess passes under the hopper it becomes filled with fuel,

4 to be discharged on reachingtheexit-opening.

When two-fined boiler or double furnace is to be supplid there may be one of such apparatus to each furnace or stoker, or one apparatus may supply both furnaces or stokers. In the latter case there will be a double incline placed immediately under the exit-opening, so that part of thefuel may pass down the incline to the right hand and part down thein-' cline to the left hand; or the receptacles may extend a portion of the length of the roller, and the receptacles on theright hand supply the furnace or stoke'r onthe right, the receptacles to the left supplying the left of thefurnace or stoker. i. l

The receptacles may be of variousforms, so as to vary the dischargefro'm any one receptacle.

It will be obvious that the roller, instead of being entirely inclosed within acylinder, would answer the same purpose if partly inclosed or embraced by a concave neck or concave bottom of the hopper.

-In connection with the improved feed-rollerof inclination being readily adjusted by screw- 7 shaft,acco1 'ding to the speed andthrow of the fans, so that the fuel shall be diverted and directed upon and over the whole surface of the bars, the throwing of fuel upon and over the bridge'being entirely obviated.

. Such being the nature and object of this my said invention, I will proceed to describe the same in detail; and in order that the invention may be fully understood, I have hereunto an= nexed two sheets of drawings illustrative thereof, and have marked the same with figures and letters of reference, the same letter referring to the same part in the several views orfigures.

Figure lis afront elevation of double-fined -boiler having my apparatus attached. Fig.2

is a side elevation of Fig. 1, partly in section. Figs. 3, 4, 5, 6, 7, 8, 9, 10, and 1.1 are details drawn to an enlarged-scale.

Ais a hopper or hoppers, the bottom or lower part of which is in communication with a cylinder, B, the under side of which is provided with an opening, F, for the exit of fuel. Within the cylinder is a roller, 0, caused to rotate slowly by gear wheels D, D, D and D or other driving apparatus. The periphery of the roller is (atintervals apart) reccssed,form= ing receptacles E, within which coal (as the ceived. The continued rotation bringsthe-receptacles E over exit-opening F. through the cylinder B, by way of which the fuel passes out to the furnace or to the mechanical stoker,

and so as each recess E passes under the hopper A it becomes filled with fuel, to be dis charged on reaching the exit-opening F.

When a two'flued boiler or double furnace is to be supplied there may be one of such apparatus to supply both furnaces or stokers, as shown at Figs. 1 and 2. In the latter case there will be a double incline, G, placed immediately under the exit-opening F, so that part of the fuel may pass down the incline to the right hand and part down the incline to the left hand 5 or the receptacles may extend a portion of the length of the roller. (See Figs. 6 and 7.) The receptacles on the right hand supply the furnace or stoker on the right, the receptacles to the left supplying the left of the furnace or stoker.

The receptacles may be of various forms, so as to vary the discharge from any one receptacle. (See Figs. 8 and 9.)

It will be obvious that the roller, instead of being entirely inclosed within a cylinder, as at Figs. 3 and 4, would answer the same purpose if partly inclosed or embraced by a concave neck, as at Fig. 5, or concave bottom of the hopper.

In connection with the improved feed-roller above described, I employ for double -flued boilers two fuel-fans or rotary distributors, H H, partly inclosed inboxes, and speeded by means of pulleys L.

The plate or plates J, for diverting and directing the fuel thrown by the fan or fans H, are placed within the flue and supported by a shaft or other axis or hinges, K, and such plate or plates may have a gradual rising-and-falling motion imparted by tappet or its equivalent; or the plate or plates may be stationary, the angle of inclination being readily adjusted by screw-shaft M, according to the speed and throw of the fans, so that the fuel shall be diverted and directed upon and over the whole surface of the bars, the throwing of fuel upon and over the bridge being entirely obviated.

Having thus fully described the nature and particulars of this my said invention, together with the manner in which the same is to be performed or carried into practical effect, I would observe that in order to fully explain the application and use of my invention it has been absolutely necessary to refer to and describe parts which are not new. I would therefore have it understood that I limit and confine my claims to-- The combination, with asuitable hopper and a roller arranged above discharge mouth of the same, and having peripheral recesses, of one or more fans or distributors and mechanism for imparting motion thereto, and one or more pivoted deflecting-plates made adjustable for diverting or directing the fuel projected by the said fans or distributors over the surface of the bars, substantially as herein shown and described.
