@TTTE' ST" TIMOTHY CARROLL, OF ANAHEIM, CALIFORNIA.

HOPPER.

Specification of Letters Patent.

Patented Oct. 11, 1910.

To all whom it may concern:

Be it known that I, TIMOTHY CARROLL, a citizen of the United States, residing at Anaheim, in the county of Orange and State of California, have invented a new and useful Hopper, of which thefollowing is a specification.

This invention has relation more particularly to that class of hoppers designed for use in connection with Crematories or other apparatus for the incineration of waste material, rubbish, garbage, etc.

One of the objects of this invention is to produce a practical hopper which is so constructed that the escape of the injurious fumes, smoke, and heat is prevented when the material to be burned or destroyed has been dumped into the crematory, and which can be safely and readily manipulated by the attendant to admit the material to be burned.

An object of the invention is to provide a novel hopper adapted to be dumped into from wagons or carts on either side thereof, or on both sides thereof, provision being made whereby the attendant may dump into either of two or more openings from either side of the hopper, or can dump a part of the load into one side of the hopper and another part of the load into the other side of the hopper without moving the vehicle from which the dumping takes place. In this connection an open hopper is provided having in its bottom al plurality of openings; and a plurality of covers are centrally hinged, each adapted to swing over one of said openings and restupon the rim of the hopper, or to swing over backward to rest on the other cover, or to be held upright midway of the hopper.

Other features and advantages of the invention may appear from the subjoined detailed description.

It is one of the main objects of this invention to produce a hopper which may be operated by any inexperienced hand, and furthermore, to combine means whereby the openings in said hopper to the crematory may be respectively opened and closed alternately or simultaneously.

Tt is to be understood that this invention relates to Crematories in which intense fire is maintained for the rapid combustion of materials diflicult to consume, and that in consequence great danger has heretofore existed in the operation of such Crematories resulting in the loss of human lives and also ofthe teams employed for hauling the garbage to the Crematories.

An object of this invention is to provide means whereby the work of dumping the garbage into the crematory may be accomplished Without any danger whatever to the operator, driver or team. This advantage is secured by peculiar arrangement of openings into the top of the Crematories and covers for such openings, and also the provision, construction and arrangement of means whereby the covers may be operated without any danger to operators, drivers or other persons connected with the work.

The accompanying drawings illustrate the device in which- Figure l is a top plan view of my improved hopper; Fig. 2 a vertical longitudinal section; Fig. 3 a side elevation showing the means for raising and lowering the covers, Figi. i a'longitudinal vertical section of a modified form, and Fig. 5 a top view of Fig. l on a reduced scale. Fig. 6 is a to view of a hopper having the same genera form as that illustrated by Fig. l, a single opening instead of a plurality of o enings being shown on each side of the ivision wall.

The upper portion l of a crematory is provided with a cap-plate 2 having a plurality of hopper-openings 2, and it is the object of my hopper to provide means for discharging material into the crematory through these openings. The hopper is rectangular in plan and has vertical outer frame walls 3 and inclined inner hopperwalls 4, said hopper-walls leading to the openings 2. End walls a connect the ends of the hopper walls 4. An A-shaped division wall 5 connects the end walls a to divide the hopper into two equal parts, said division wall leading to the inner side of the openings 2 in opposition to the walls 4..

In the construction shown in Fig. 1 there are two openings 2 on each side of the division wall 5, and a partition having reversely-sloping walls separates these openings transversely of the wall 5. The height of the division wall 5 is about one-third of that of the walls 3 or 4. Two division covers 6 are hinged to the top of the division wall 5, said division covers being adapted to swing to an inclined position and rest upon the upper edges of the walls 3 and 4:; said division covers being operated by means of a chain 7 running over a pulley, said pulley being centrally suspended from the cross-beam 8 supported by the standards 9 which are mounted on the ends of the hopper. The several walls of the hopper arranged as described provide four openings 10 in the bottom of the hopper registering with the openings 2 in the cap-plate 2 of the crematory. Supplemental covers 11 are hinged to the inner faces of the hopperwalls t near their lower edges, said supplemental covers being adapted to swing downwardly to horizontal positions against the division wall 5, and said supplemental covers being operated by chains 12 connected to spools 13 iXed upon shafts 14k mounted upon y the frame walls 3 and operable by cranks. Clutches 15 are provided upon the shafts 14, one clutch for each spool, so that by operating the clutches the supplemental covers may be operated independently or simultaneously. To further close the openings 2 and insure the retention of the fumes and heat in the crematory, slides 16 are provided on top of the cap of the creniatory and below the hopper, said slides preferably operating crosswise of the hopper and each slide controlling two of the openings 2.

It will be seen from the drawing represented in Fig. 1 that a double hopper can be formed out of this arrangement by siniply operating the chain 7 and thereby holding the respective division covers-6 upright in a position parallel with the side walls, and that a single hopper may be formed by throwing both of said division covers over to one side and in this case only one side of the hopper would be open for the reception of material.

In the modification shown in Fig. t, three openings are thus shown in the bottom of the body portion extending the full width or length of the hopper. These openings are shown at 17, 18, and 19 -in a row. To close said openings, supplemental covers 20 are provided in the bottom of the hopper, said supplemental covers 2O being operable by means of a chain and spool arranged on the side of the hopper-body. Division covers 21 are provided to lap over the supplemental covers 20, these covers being operable by a chain and pulley in like manner as in Fig. 1. Thus I provide three distinct independently-operated closures for each opening into the crematory. This arrangement of covers and hopper provides for three separate openings through the cap to the creinatory, each of which is independent of the other and two of which may be used at one and the same time. All three of said openings may be used alternately by adjustment of the covers from one side to the other, but the two outer openings may be used at the same time to receive the loads from two wagons one on each side. In that case the covers 21 would be raised by means of the chain 22 to a vertical position.

By providing tor each opening two covers hinged at opposite sides ot' the opening, one toold over the other, said covers being operable either simultaneously or independently of each other, and both adapted to swing downwardly to close, and upwardly to open the openings, a great avoidance ot danger is made possible.

A vehicle loaded with garbage may be brought to the edge of the hopper while the hopper is closed by both covers, as shown at the left in Fig. 2, and then the division cover G may be drawn into upright position while the hopper is still closed, thus making a free open passage upward from the inner tace of the division wall of the hopper up which passagew the i'unies and tiaine may bc emitted when the supplemental cover 11 is opened. r1`he division cover 6 when thus raised to an upright position provides a shield or fender to prevent the blasts of air across the hopper which might fan a Haine outward to the injury or inconvenience of the vehicle, the team, or the attendant.

Thilo I have shown and described one hopper having tour openings as in Fig. 1, and anctlier hopper having three openings, as in Fig. et, it is within the scope of `this invention to change the number of openings as may be desired, and it is obvious that other changes in size, shape and arrangement of parts may be made without departing troni the spirit of my invention. For instance, the openings instead oit being rectangular may be square, oval, round, or any other desired shape.

In Fig. 5 I have shown a hopper having two openings ot the torni shown in Fig. 4, and in Fig. 6 I have shown a hopper having two openings oit the construction shown in Fig. 1, a single opening instead ot a plurality of openings being shown on each side of the division wall.

Referring to Figs. 1 and 2, for instance, a load of garbage may be hauled to the letthand side of the hopper, the slides 16 moved outwardly to uncover the openings 2, the right-liand one of the covers 6 raised to a vertical position, either of the covers 11 upon that side of the hopper opened, and a part ot. the load dumped; then the other cover 11 opened and another part of the load dumped; then both of the covers 6 may be swung over to the lett-hand side of the hopper, either one oi both of the remaining covers 11 may be swung open and the balance of the garbage from the load at the left-hand side of the hopper may be dumped upon the covers G and over said covers into the right-hand opening 2, thereby making it possible to dump the load into any desired one of the openings 2 from one side of the hopper. TWhen it is desired to drive up to the right-hand side of the hopper the slides 6 may be moved to the left-hand side. The inner or lower' doors l1 or 20 as the case may be, close downwardly by gravity and come to rest above the openings in the capplate so that in case either of the closures is fully down, the opening is positively closed against accidental reopening.

I claim:
