This invention relates generally to stokers and particularly to an ash' elevator for use'inconjunotion therewith.

.The'mai'n object of this invention is to provide a means for accumulating and storing ashes that will utilize most advantageously the space that maybe available near tlie'boiler or furnace. In other'w'ords'jl have endeavored to obtain the maximum practical stora'ge capacity when 'occu 'pyin'gthe minimum number of square Qfee t jof floor space.

The second object is to provide a simpl and eificientform of distributingmechanismand storage buckets which will provide themaximurn amount of ash storage without requiring an unof storage can which will not be'difjcult to empty.

The fourth object of this inventiojnis to socjonstruct the ash handling system that the yarioiijs joints may easily be'renderd dustjtight.

The mechanism thus far described collects ashes from the furnace l and elevates them and discharges them through the tube 34. Any equivalent mechanism for accomplishing this purpose may be employed without departing from the spirit of this invention.

Turning now to my invention as more clearly set forth in Figs. 2 to 6, it will be seen that the ash distribution and storage unit consists of an outer casing 56, over the top of which is placed a removable cover 5! and beneath which is formed a floor 58. Disposed under the floor 58 are a battery of ash cans 59, which are shown in plan in Fig. 5. Each ash can 59 is elongated, as shown in Fig. 6, and tapered about one fourth inch per foot. In normal practice the cans are about four and one half feet tall and six inches square at the top, and about four and one half inches square at the bottom. All four sides are tapered, but a lesser number may be tapered without seriously detracting from the utility of the device. Around the upper end of each ash can 59 is secured an angle bar rim 66, beneath which is secured a handle 6|. Below the handle BI is secured the elongated hinged handle 62, which is made fast to the cross straps 63.

The floor 58' is provided with a plurality of round holes 64, one over each can 59. Resting on the floor 58 is a distributing plate 65 provided with holes 66, all of which can register with the holes 64 at the same time when the distributor plate 65 is moved in one direction in order to permit ashes to flow therethrough into the cans 59, whereas all of the holes 64 may be closed when the plate 65 is moved into the position shown in Fig. 2. The plate 65 is provided with two slots 61, through which extend the bolts 68 which, like the bolts 69 disposed beyond the outer boundaries of the plate 65, extend through the short horizontal shafts 16 and the long horizontal shaft ll. The

bolts

68 and 69 pass freely through the upright tubes 12, which are secured to the floor plate 58. The lower ends of the

bolts

68 and 69 pass through the horizontal bars 73.

Partition walls 74 extend between the floor and 45 the back of the casing 56, while the transverse wall 75 extends between the partitions 14. The

walls 14 are provided with slots 16 to permit the free vertical movement of the shafts and H.

Mounted on the shafts 10 and H are the rollers I1 and i8. Beneath the rollers 11 and 18 are disposed the plates 79, having the inclined cam surfaces 89 formed thereon, upon which the rollers I1 and 18 can rest, as shown in Fig. 3, allowing the cans 59 to move to a lowered position, that is,

one in which they can be withdrawn from the casing 56 by opening the door 8i. It is desirable to provide a rubber gasket 82 on the under side of the floor 58, against which the rim 60 of the ash cans 59 can press when the earns 59 are in a raised position, as shown in Fig. 4. The plates 19 are secured to the distributor plate 65. One set of plates 79 are separated, as shown in Fig. 3, to provide clearance for the discharge tube 34, while the other plate 19 is provided with a slot 83 as shown in Fig. 4, to provide clearance for the worm shaft 46, which journals in the bearing 84, which in turn is secured on the floor 58 by means of the bolts 85. Also secured on the floor 58 is a standard 86, through which extends the discharge tube 34. The end 35 of the discharge tube 34 extends through the wall 14.

Journaling in the bearing 84 and the standard 86 is a shaft 81, on which are secured the pinions 4 88 and 89 respectively. The

pinions

88 and 89 mesh with the racks 90 and 9|, which are secured across the top side of the members 19 by means of the bolts 92. Motion is imparted to the shaft 81 by means of the crank 93.

The operation of this portion of the device is as follows: Assuming that the buckets 55 are carrying ashes l4 upwardly on the inside of the belt 52, it follows that when they reach the uppermost turn of the belt that they will be dumped and fall through an opening 94 in the tube 34, and are then carried by the discharge worm 34 onto the plate 65. It follows that the ashes will be deposited upon the plate and will fall through the

nearest holes

64 and 66 if they are in register. .When any particular can 59 is filled, the ashes are pushed onto the next nearest unfilled can. If the attendant does not empty the cans, the only damage which can occur is to raise the cover 51 and permit the ashes to spill upon the floor outside of the cabinet. If it is desired to remove the cans 59, it is only necessary to rotate the crank 93 which causes the plate 65 to slide to the position shown in Fig. 2, that is, so that the

holes

64 and 66 are out of register, the last portion of the movement causing the cans 59 to be lowered.

While I have thus illustrated and described my invention, it is not my desire to be limited to the precise form shown herein, and I intend to cover such forms and modifications of the invention as fall fairly within the appended claims.

I claim:

1.
