IMPROVEMENT IN ASH-SIFTERS.,
Specification forming part of Letters Patent No. 144,466, dated November 11,1873; application filed July 19, 1873.
\ sponding parts.
My invention has for its object to furnish an improved ash-sifter which shall be lso constructed that the coal may be sifted without the escape of the fine ashes through the room, and which shall at the same time be simple in construction and convenient in use. The invention will first be fully described, and then pointed out in the claim.
A is the box, which is provided with a close cover,B, and is supported upon legs C,of such v. a length that an ash-pail or coal-scuttle may be placed beneath the bottom of the box A to i receive the ashes, which are allowed to escape through a hole in the bottom of the box A, by
` drawing out the slide D. In one end of the box A is formed a spout, E, through which the coal may be allowed to escape by drawingup the slide F. A The inner endof the spout E projects into the box A, and its outer end projects sufliciently to allovT a coal-scuttle or other receptacle for the coal to be placed beneath it. G
Vis the sieve, the forward end of which is provided with a door, g', hinged at its upper edge to a cross-bar attached to the forward part of the upper edges of the ends of the sides of said sieve. The door g is fastened shut by a bolt or other fastening, H, which catchesupon a catch attached to a bar attached to the forward part of the lower edges of the sides of I is a spring, one end of which is the sieve G, and its other end to the door gf,
y and which, as soon as the fastening H is re- J, attached to the box A, as shown in Figs. 1 and 2. The sieve G is further supported by the rod K, to which it is attached. One end of the rod K is pivoted to one side of the box A, and its other end passes through a slot in the opposite side of the box A, and has a handle attached to it for convenience in operating the sieve. The rod K also passes through a plate, L, which is placed upon the outer side of the box A, over the slot in said box, and slides in keepers attached to theV box, so as to prevent any ashes from escaping through the slot in which the rod K works. M is a long pin, which is slipped in through a hole in the side of the box A, so as to pass above the rear part of the sieve G, and prevent the said sieve from tipping before the said pin is withdrawn.
In using the sifter, the ashes and coal to be sifted are poured into the sieve G, and the handle of the rod K is moved back and forth quickly. When the ashes have been all shaken out, the slide F and the pin M are withdrawn, and the handle of the rod K is turned slightly, causing the forward end of the sieve G to drop. As the forward end of the sieve G descends,
the fastening H comes in contact with the inner end of the spout E and becomes Junfastened, thus allowing the coal to escape through spout E into the receptacle placed beneath said spout. As soon as the coal has been discharged, the slide F is inserted, and the sifter allowed to stand until the ashes have all settled. The slide D is then withdrawn and the ashes allowed to escape into the receptacle scribed. v
LEVI MARSH.
