TO ALL WIflOM IT MAY CONCERN:

, Beit ltnown that l'rHENRY ROBES, of Cla-rence Centre, in the county of Erie, and State of New York, have invented certain new' and useiul Improvements in Plaster-Servers; and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings, making vor stirrer E and the turned-up edges, 7i it; of the discharge-holes.

part of` this specification, in which- Figure 1 is an end elevation. Figure 2 is a plan. FigureS is a transverse vertical section of the hopper and its adjuncts. Like letters of lreference indicate corresponding partsvin all the figures.

My invention relates to the hopper, having a lifter or stirrer provided witlrwire loops extending spirally around the shaft, and having also the edges ofthe discharge-holes inthe bottom turned up opposite the motion of the sweeping-brush, which is situated intermediate with the lifter and holes. It further consists in the arrangement of parts for imparting motion to the lifter and brush, as hereinafter set forth.

In Vthe drawings, A indicates the main frame, B a field-roller running therein, and C the hopper.

ttachedto one'end of the hopper is a bar or arm, D, hinged at a, which projects over the roller.

A friction-roller, b, is 'attached t o lthe inside of this arm, and, running on large roller B, gives motion to a pulley, c, on the outside of the arm, lwhich isconnected byva chain or band to a pulley, cl, which revolves the shaft of the stirrer or lifter Eyinside the hopper. 4

This lifter is provided with a series of eyes or loops, e e e, of wire, arranged spirally around the shaft, as clearly shown. l

The outer end of the arm D-is held down by elastic bandp. With it is also connected a toggle, r, which, by straightening, serves to raise the friction-gear from contact with the roller. i

Tile bottom of the hopper is'cut into narrow openings, g g, running crosswise of the hopper. The inner edge of cach opening is turned up, presenting a-raised ange, as shown at lz, which comes in contact withthe expclling-brushes,ff, of shaft G as thc 'latten turns. These angcs are formed by simply bending upthe edges of `the holes. i l

F is the ordinary graduating slide at bottom of hopper. v

` The brush-shaft is operated by a pulley, j, outside the hopper, and revolved by a band or chain from pulley ci'.

i Thcgrcat advantage in the arrangement of the hopper, as above described, consists in the use of the lifter Plaster is of a very heavy and damp nature, and has a tendencyto pack in the hopper, so as to impede the brush.

Thcloops e e cut into the'hoi-ly of the plaster and raise the mass up bodily from the brush, and, by-their sifting action inpassing around,always keep itlight and in just such condition as'td be acted on and expelled easily. The spiral arrangement of the loops around the shaft greatly assists in producing this result. Simple radial pins or arms would not accomplish this result, as they worlcpnly in a plane.

The turned-up edges, h, of the discharge-holes, by standing opposite the motion of the brush, catch the plaster as it is carried around and force it out beneath. Were it not for these, the plaster would be carried around4 in'asolidniass, and be very imperfeetly discharged.

The combined-use ofthe loo`ps e and raised edges z, in connection with the brush Gr, insures a very effective 'and equal spread of the plaster upon the ground.

"The arrangement of' the hinged arm D with baudp and toggle r is of great value in practical operation, as itiscrves to engage and disengage the gearing in the simplest and most expeditious manuel'. The band holds the gear b firmly in contact with the roller. and to disengage it at once, it is only necessary to straighten the toggle, as shown in red lines.

What I claim'as my invention, and desire to secure by Letters Patent, is-

The arrangement, in connection with the intermediate brush G, of tho lifter E, provided with the spiral loops e e, situated above, und the xoisedv edges'h h of the discharge-openings situated below said brush, the whole operating in the m'anner and for the purpose specified.

I also claim the hngedorm D with holding-bandp and elevating-toggle #and serving, with gear b, to give motion to the partsin the hopper", as sel; forth.

- In witnes whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

I HENRY RODES..
