1 '0 all whom it may concern:

Be it known that I, Trroirms F. FEHRLE, a citizen of the United Eitates, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hoppers, of which the following is a specification.

My invention relates to improvements in hoppers and particularly relates to hoppers to be used in connection with machinery for treating wool.

The object of my. invention is to construct a hopper through which a greater amount of material may be passed, within a given time than heretofore by reason. of its improved construction; a further object of my invention is to construct a hopper having the air inlet and the conveyer outlet apertures formed within the converging walls of the hopper, and thus dispensing with the usual form of vertical throat below the converging walls of the hopper. which throat tends to clog the hopper; and a still further object of my invention is to admit the air blast from the air supply pipe directly into the angular portion. of the hopper so that the air blast can keep the wool in the hopper agitated and force it through the hopper with greater speed than is possible when the hopper is constructed with a throat portion between the hopper proper and the discharge opening of the conveyor pipe. By my improved. construction of the hopper economy of space is obtained, as a low-down type of hopper thus provided, which may be used in connection with a machine having the discharge opening close to the floor level.

Referring to the accompanyingdrawings; Figure 1, is a perspective view of my improved hopper shown in use with a-wool drier; Fig. 2, is a plan view of the hopper; Fig. 3, is a side view of the hopper, partially in section; and Fig. 1, is an end view of the hopper.

in the accompanying drawings in which like reference characters refer to like parts, the hopper 1, consists of the sloping side walls 2 and 3 and the end walls 4: and 5. The converging walls of the hopper form an inverted truncated pyramid. The side walls 2 and 3 of the hopper, are continuous and form a curved bottom portion 6, connecting the side walls 2 and 3.

The walls of the hopper are constructed of sheet metal and are reinforced by a rec= tangular top frame 7, formed of angle-iron,

and also by the supporting members 8, also of angle-iron. The supporting members 8 are substantially U-shaped, as shown in the end view Fig. 4, having a lower base portion 9 and side portions 10, which latter embrace the side walls of the hopper and are conings formed therein atthe places where the pipes 12 and 13 are attached thereto and the said openings formed in the end. walls are located between the apex and the base of the polyhedral angle.

The bottom portion 6 of the hopper is on the same level with the lower portion of the pipes 12 and 13 and thus forms a continuous bottom surface between the inlet pipe 12 and the outlet pipe 13.

The air as it is forced through the inlet pipe 12 strikes the deflector plate 15, and is directed toward the bottom portion of the hopper and carries the wool from the hopper into the outlet conveyor pipe 13.

By this construction of the hopper an excess accumulation of wool in the hopper will not clog the mouth of the outlet pipe 13, as the flaring walls of the hopper permit the mass of material to expand as it is lifted by the air from the inlet pipe 12.

in Fig. 1, the hopper is shown located at the discharge outlet of a wool drier 20 in which the wool is dried by being conveyed through the drier upon the conveyer tables 21, in the usual manner.

Having thus described my invention I claim and desire to secure by Letters Patent:

1. A hopper comprising flaring walls, a bottom portion connecting the flaring walls, an outlet conveyor pipe connected with the hopper above the apex of the angle formed by the said walls of the hopper, an air inlet pipe connected with the hopper, a de flector plate located within the inlet pipe adjacent to the end thereof attached to the hopper, and said deflector plate inclined at an angle to direct the air toward the bottom of the inlet pipe and the bottom of the hopper.

2. A hopper comprising flaring side walls, a curved bottom portion connecting the side walls, flaring end walls connected with the said side Walls, said end Walls extending to the said bottom portlon andhavmg openlngs 7 formed therein, horizontal pipes having angular Initered ends corresponding to the angle of the end walls and connected with the end walls, said pipes registering With .the said openings formed in the end Walls,

said pipes located on the same level with hopperi the bottom portion of the hopper, and reinforcing frame members attached to the 10 MARTHA H; QUINN.
