ASH-SIFTER.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed March 2, 1917. Serial No. 152,110.

To all whom it may concern: 7

Be it known that I, WILLIAM MCCORMICK, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Ash-Sifters, of which the following is a specification.

The present invention relates to improvements in ash sifters.

In carrying out my invention it is my purpose to produce a device of this char acter wherein the cinders may be easily and quickly separated from the ashes, the said cinders being retained in a suitable compartment separable from the ashes, whereby either the ashes or the cinders may be inclependently removed, the construction being such as to prevent the escape of dust during the sifting operation.

It is a further object of the invention to produce an ash sifting apparatus which shall be of a simple construction, cheap to manufacture, easily operated and which will accurately perform the functions for which it is devised.

With the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings:

Figure 1 is a perspective view of an ash sifting apparatus constructed in accordance with the present invention,

Fig. 2 is a vertical longitudinal sectional view through the same,

Fig. 3 is a transverse sectional view approximately on the line 3-3 of Fig. 2,

Fig. 4f is a transverse sectional view approximately on the line 4-4i of Fig.2,

Fig. 5 is a horizontal sectional view approximately on the line 55 of Fig. 2

Fig. 6 is a top plan view of the casing of the device, the closure being in its open position and the sifting member being removed,

Fig. 7 is a perspective view of the reciprocatory member or slide, and

Fig. 8 is a perspective view of the sifter,

Referring now to the drawings in detail, the numeral 1 designates a suitable receptacle which, in the present instance, is boxshaped and has an open top provided with a hinged closure 2. Upon the inner face of the closure are provided depending elements 3 providing breaker or agitator members which contact with the ashes arranged in edges of the drawer proper so as to fully close the opening in the receptacle and prevent the passage of dust through the opening when the drawer is in its closed position. The drawer is, of course, provided with the usual handle whereby to facilitate the sliding thereof.

The receptacle 1 at the upper portion or mouth thereof is provided with inwardly and downwardly inclined members 5 and below the said members is provided with longitudinally extending cleats forming ways 77 for a reciprocatory member hereinafter to be described. The hopper-shaped mouth of the receptacle is adapted to receive the hopper-shaped body 8 of the sifter member, the bottom of which is reticulated, as

indicated by the numeral 9, and the said body, at the sides thereof, is provided with downwardly projecting studs 1010. The hopper 8 at the sides thereof is provided with revoluble catch members 11 arranged in suitable bearings 1.2, and each including a rod-shaped jaw having its upper portion offset, as at 13, and received in the slot in the cut away portion 1 l of the bearings. The outer ends of the rods are provided with offset handles 15 and the lower ends of the rods being provided with offsets forming a hook member 16. By this arrangement it will be noted that when the central offset portion contacts with the end wall provided by the opening in the bearing 12, the hook-shaped members will be turned angularly or downwardly with respect to the hopper, but when the rods are turned so that the handles are arranged against the side walls of the hopper, the said hooks are disposed below the reticulated face of the hopper. If desired, the reticulated face of the hopper may be provided with transverse reinforcements.

Mounted for rectilinear movement in the ways 7--7 is frame 16, preferably compris= ing spaced side and end members. The end members are each provided with transversely arranged elongated slots or openings l7 1.?

adapted to receive the projecting studs 10' that has its free end connected with the.

crank portion 21 of a shaft 22, the said shaft being journaled in suitable bearings 23 and 24 in the receptacle. To one end of the shaft 21 is secured a pinion 23 which intermeshes with a similar pinion 24 arranged upon a shaft 25 that is journaled in suitable bearings secured upon the inner face of the receptacle and which shaft 25 projects through a suitable opening in one of the sides of the receptacle, the said projecting end of the said shaft being provided with an operating handle 26.- By turning the shaft 25 it will be noted that the inter-meshing gears will revolve' the shaft 21, oscillating the pitman 20 which being connected with the slide im parts a rectilinear movement thereto. The sifter member, it will be noted, may be readily disassociated from the slide by operating the catch members so that the handles for the sifter and these handles then pro- I 7 moving said hopper. thereof are turned inwardly of the hopper 7 guides secured therein, a frame slidable on said guides, a hopper disposed upon said frame and having reticulated bottom, studs on the bottom of said hopper at its corners engaging within slots in said frame, and means for reciprocating said frame.

2. An ash sifter comprising a receptacle, guide cleats secured therein, a frame slidable on. said guides, a hopper having a reticulated bottom disposed upon sald frame,

brackets securedupon the end walls of said hopper, rods journaled through said brackets and prevented from longitudinal movement therein, offsetson said rods engage.- able'with the end walls for limiting the rotation of said rods, hooks on the lower ends of said rods engageable with said frame, means for reciprocating said frame, and angular extensions on the upper ends of said rods serving as handles for turning said hooks to their operative and inoperative positions and further serving as handles for re Intest-imony whereof I afix my si nature.
