METAL BODY FOR THRESHlNG-MACHINES.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed September 4, 1902. Serial No. 122,145.

To all whom it vita/y concern:

Be it known that I, WARREN A. SPENCER, a citizen of the United States of America, residing at Union Springs, in the county of Cayuga and Stateof New York, have invented certain new and useful Improvements inMetal Bodies for Threshing-Machines, of which the following is a specification.

This invention relates to improvements in threshing-machines, and more particularly relates to the bodies or casings thereof.

The object of the present invention is to provide a threshing-machine body which is formed entirely of metal, so that the same will be more durable than the bodies of wood usually employed and at the same time which will prove less expensive and lighter in construction and entirely Water, weather, and fire proof.

A further object of the present invention is the provision of a thresher-body embodying in its construction simple and efiicient means for protecting the various pulleys and belts applied to the exterior of the machine from accumulations of dust and dirt and from the destructive results incidental to the elements. With these general objects in view and others which will appear as the nature of the improvements is better understood the invention consists, substantially, in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings, Figure 1 is a side elevation of a thresher-body constructed in accordance with the present invention, the protecting-plates at the side of the body being removed. Fig. 2 is a top plan view thereof, and Fig. 3 is a rear end elevation.

Referring to the drawings, the numeral 1 designates a thresher-body which is of the usual shape and adapted to receive the usual separating and cleaning mechanism; but as the latter does not enter into the present invention it is not deemed necessary to illustrate the same.

The body 1 comprises the usual sides 2, a top 3, and a bottom 4, and said parts are all formed of metal, preferably iron or steel. So far as possible it is desirable to form the parts mentioned of single sheets; but when this is not-possible said parts may be formed of sheets of suitable area and riveted together at their contiguous edges in order to provide a substantially integral structure. The sides 2 may be perforated. at suitable points, as at 5, in order to provide for the reception of bearings for the various shafts of'the internal mechanism, and said sides are also provided with vertically-extending braces or stays 6, said braces or stays preferably being in the form of angle-irons. It will be observed that the top 3 extends over the entire portion of the body, excepting a suitable length at the forward end of the body, which length is provided with no top in order to facilitate the introduction of the grain to the separating mechanism, and the body at the front end is provided with the usual inclined feed-board 7. The body 1 is also provided with the usual fan-casing 8, which casing is suitably reinforced, and said casing is supported by the immediately-contiguous braces or stays 9, and which braces or stays may also provide supports for the bearings of the fan-shaft. Arranged adjacent to the fan-casing 8 is the usual shoe 9, which may be open-work, said shoe containing the usual cleaning mechanism.

For the purpose of protecting the pulleys and belts arranged at the exterior of the body the edges of the top 3 are extended in order to project beyond the sides 2, and thereby provide overhanging eaves 10, as clearly shown in Fig. 3, said eaves extending from the front end to the rear end of the body. The eaves 10 are supported through the medium of downwardly and inwardly inclined braces or stays 11, which braces or stays are secured in a suitable manner to the sides of the body, and hinged to the outer edges of the eaves 10 are depending protecting-plates 12. It will be understood, of course, that the width of the eaves 10 is such that the depending protecting-plates will have sufficient clearance from the pulleys and belts as not to interfere with the operation of the same, and said protecting-plates are of sufficient dimensions as to project down to a point which will effectually conceal and protect the pulleys and belts on the exterior of the body. When so desired, the plates 12 may be swung from the vertical position which they normally occupy to a horizontal position and maybe supported therein in order to provide additional surface at the top of the machine when the latter is stationary.

From the foregoing description it will be seen that the hereinafter-described invention provides a body for a threshing-machine IIO which is practically indestructible, being Water, Weather, and fire proof and more durable and lasting than the ordinary wooden bodies usually employed, and, moreover, the invention also provides simple and efficient means for protecting the various pulleys and belts applied to the exterior of the machine from accumulations of dust and dirt and also from the destructive results incident to exposure to the elements.

Having thus fully described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

The combination with athreshing-machine body formed of metal, and comprising sides, bottom and top, said body being provided at its forward end with an inclined feed-board, the top of said body terminating at a point removed from the extremity of said forward end to provide a horizontally-arranged opening for the introduction of grain to the interior of the body, the edges of the top being extended and projecting beyond the sides of the body to form overhanging eaves, protecting-plates connected to said overhanging eaves and depending therefrom for protecting the pulleys and belts at the exterior of the body, downwardlyinclined stays arranged beneath said eaves and connected to the latter and the sides of the body for sup porting said eaves, said plates being hinged to said eaves and adapted to be swung to a horizontal plane for increasing the surface of the top of the body, a circular fan-casing and shoe arranged at a point in the bottom of said body, intermediate its ends, and stays arranged at the sides of the body for strengthening'the same, the stays immediately c011- tiguous to the fan-casing and shoe being extended and forming supports for the same, substantially as described.

In testimony whereof I hereto afiix my signature in presence of two witnesses.

WARREN A. SPENCER.
