MICHAEL MENDEL, OF NEVET' YORK, N. Y.

SIIETING DEVICE.

Be it known that 1, MICHAEL MENDEL, a

citizen of Great Britain, and resident of New York City, in the county of Kings and State of New York, have invented certain new. and useful Improvements in sifting Devices, of which the following is a specification.

My invention relates to sifting devices and inthe present'case myobject .is to provide adevice adapted to sift ashes and other such substances. By changing the mesh, I may adapt the construction to sift flour and Referring to the drawings which form a part of this specification:

Figure 1 is'a side elevational view of a construction embodying my invention.

Figure 2 -is a plan view. a Figure ,3 is a view of the binding ring which holds thebag to the screen or carrying portion hereinafter referred to as the llllgw,

is Figure i is a plan view of the pail and ring on an enlarged scale, disclosing the meansfor holding them together.

Figure 5 is a side view, partly in section, of the ring,'bag and sieve, and the pail in a position in theringr Figure 6 is a plan view as indicated by the arrows in Figure 5, of the sieve and its hinge construction. a Figurei? is a frag'mental view disclosing a sidecviewof the construction of one of the means for holding, the pail and ring together. 1' l A indic'ates a frame which carries a bracket 13 which maybe of rigid construction or resilient to serve itself-as a spring in case the movement desired is not too great for a spring of this character. cal spring which is attached to the element B as indicated, at its upper end,-'and to a spider bracket D at its lower end. Sus- %ended from the periphery of the bracket are chains E-EE, etc., the lower ends of which are provided with snap-hooks F-'-F -F, etc., which in turn are connected .to the rings G-G-G, etc., fastened to-the rim H of the screen ring H, which rim is formed into a hollow beaded ring portionto strengthen and stiifen the construction. A

similarconstruction is made at its lower edge of the ring H and indicated by The bag I is large enough at its upper end C indicates a heli-- Specification of Letters Patent. 7 Patented J an, 3, 1922,

to pass over the bead H and is detachably held thereonby a hoop J, the ends of which are connected by a link cam construction K and L, the hook K being connected to one end of the hoop J and pivotally to the link L at L which is at.a point intermediate its 1 "and held after a' sifting operation. An outlet 0 is provided at the bottom of the bag and acord P is held around the neck I of the bag so that by looseningsaid cord the ashes can be dumpedwhere desired. A corrugation Q is formed in the ring H to afford a strong rigid support for the abutting rim R" of the pail R and permits of using pails the diameter of the rim R of which may vary to a limited'degree. The beaded lower end H ofthe ring H is so, formedas to provide an inner flange H which serves as a support for the free sides of the hinged sieve portions S and S, the edges of the mesh of which is bound by sheet metal T l, the inner adjacent portions of which are formed to provide hinges U.U as will be readily understood. A wire (not shown) which extends through eachof the loops of the hinge portions, is fastened to the ring H and either side of the sieve portion can be lifted or both sides lifted together'and held by the spring V. This function is ac. complished by connecting one end of the spring V to a depending hook or ring V fastened to one screen element and to a similar hook V fastened to the adjacent screen element, both being below the median line of the hinge U when the screens are in the position shown,,and above the median line when the screens are in a vertical position, due

'to the V and V moving in the arc of a cireach having a hole through which an end ofthe bail is passed in the usual manner,

and the end of the bail is provided with an upset end W at a short distance from the spectively at each side of the pail, said clips I face of the clip W to permit the looped end X of the wire X to hook over the end of the bail and thus hold the pail Rte the 1 having ascreen and a spring, said'receptaring H. The specific construction is illustrated in Figures 45 and 7 and embodies two spaced brackets Y-Y mounted on the rim H with a cross-rod or bolt Y. A linked lever Z is connected to the cross-rod Y and to'the element X. When the lever Z is pushed down its cam action draws the pail R down tight against the ring H and holds it, the action being the same as that described in holding the, hoop J.

The operation of the device is as follows: The ashes being in the pail R in its normal position and the chains E being disconnected from the rings G, the ring H is inverted and placed over the top of the pail R- and-locked thereto by the locking means X. The bag I is then attached to the ring H. The spider frame D is disconnected from the'lowerend of the spring C and inverted, and the pad and its attached ring His set thereon and the chains connected to the rings G respectively. The whole is, then inverted, thus dumping the ashes into the ring H without any dust escaping into the room. The spring C is next attached which leaves the apparatus in the condition as illustrated. The pail is then pulled downward against the resistance of the spring C. and" when released, the springreacts to lift, the load. By rapidly repeating this action the ashes are sieved, the dust going into the bag and the cinders being held in the ring H above the screen. The chains are then detached,

the pail removed, the cinders separated from the coal to be saved and screen door opened to permit the refuse to be deposited therethrough into the bag, after which the bag is detached from the ring H, the cord M tied and the operation is complete. The bag is then removed with its contents and by opening the outlet 0 the contents may be de-. posited in the ash-can without trouble.
