To all whom it may concern Be it known that 1 OWEN FRANKLIN Mivring is a specification An ob ect or the invention is t provide a sitter for sifting or screening; materials such: as sand, gravel, cracked stone, ashes and other like materials.

The invention comprehends among other features a device which can be conveniently transported from one place to another and in which the parts C(HTIPOSlllg the sitter can be readily removed for the purpose of cleaning the s' required for sitting dil'l'crcnt materials.

} A further embodiment of the invention resides in means whereby the inclination of the screen can be varied to suit the particular material that is to he sifted and winch upon a discharge opening, while the liner portions of the material. Will pass through the screen into a suitable receptacle provided therefor.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of ref erence denote corresponding parts in all the views, and in which:

Figure 1 is a side elevation. Fig. is a vertical loinjgitui'liiual sectional view; Fl 3 is a front clevat'iom and Fig. 4 is a rert1cal transverse sectional. view taken on the line el -4t in 'l ig. 2.

Referring more gmrticularly to the views use is made of a incliruiling a body 11 terminating in front and rear legs 12. ld'ounted to swing on both sets of legs 12 are supporting members 14:, having rollers 15 journaled thereon, cotter pins to being provided to pass through registrablc apertures in the front legs 12 and supporting members 14 to secure the supporting mem bers in the vertical plane of the front legs as shown, it being readily seen that it dosirable the cotter pins 16 can be removed from engagement with the supporting members 1 1 and the said members can then be swung into an inoperative position so that either the front or rear legs 12 made to repose on the ground, thus tilting the stand "tor and parts substituted when of slots 17, ilnd a casing 18 is removahly mounted within the stand 10, a horizontally arranged shaft 15), having a forlcliln agitator 20 thereon, being journalcd on the cas ing 13 with the shaft 19 arranged in the slots 17 when the casing 18 is mounted within the stand so that the said shaft will readily support the casing, as shown in the views. The shaft 10 has a crank or handle portion 21 arranged oxteriorly of the casing 18 and stand 10, for the purpose of operating the agitator 20 and renn'uably mounted to repose on ledges 22 on the inner face of the sides of the casinglS is a screen 23, the said screen constituting a cover for the cas ing 18. The screen is removably mounted so that screens of course or line mesh may be used for sitting coarse or fine materials. When mounted in the casing as mentioned, the said screen will aline with a discharge chute 2 lprojectcd from the front of the stand 10, a closure being gravitationally mounted on the casing 18 to normally close the upper end of the discharge chute. A chain 26 has connection with a staple '27 sccured to the closure and the said chain passes loosely through a staple 28 on the front of the casing 18, a hook 29 having connection with the free end of the chain and discharge chute 30, a closure 31, having an integral handle 32. being slidably mounted on the upper end of the discharge chute 30 to close the same. A hood 32 is provided for removable engagementwith the stand 10 and at the rear end thereof there is mounted to swing a closure 33 drovided to normally closet c entrance to the stand 10 and casing 18, a balllc plate 34 of a fork-like construction, being rigidly secured to an inner face of one of the sides of the hood 32 topartially restrict the entrance closed by the closure The rear part 32 of the hood is hinged or pivoted thereto, as at 32, so that it may be swung open for access to the cusing without removing the hood.

In the, use of the device described, the entire structure, first conveyed to the place of operation,. a suitable handle 35 being mounted to swing on the stand 10, in order that ths ope rstor can readily pull the sift-e1 over the grs und or floor.
