SPECIFICATION forming part of Letters Patent No. 780,826, dated January 24:, 1905.

' Application filed May 6, 1904:. Serial No. 206,757.

To all whom, it may concern: 7

Be it known that I, ABRAHAM M. O. SNEIDE, a citizen of the United States, residing at Benson, in the county of Swift, State of Minnesota, have invented certain new and useful Improvements in Separators; and I-do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to threshing machines, and more particularly to the separating-screens therefor, and has for its object to provide a separator in which changing of the sieves may be quickly and simply accomplished .and which will be so arranged that the sieves when removed will occupy a minimum of space.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is atop plan view of the present form of separator. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a side elevation of the separator.

Referring now to the drawings, there shown a frame 5, including side pieces 6 and 7 having transverse rollers 8 at their ends, the trunnions 11 of which are removably engaged with bearings 9 and 10 in the side pieces 6 and 7 In the side piece 7 the bearings are formed by the bottom of the slots 20 and 21. One of the trunnions of each roller carries a ratchet wheel 12, and disposed to engagethese ratchet-wheels to prevent movement thereof in one direction are pawls 13, which are pivoted to the side 7. Between the rollers 8 there is disposed a third roller 14, which is somewhat smaller in circumference than the other rollers and which acts as a support for the screens to be presently described.

The screens'employed in the present invention may be of wire fabric or any other suitable flexible material, but are preferably formed of strips of spring-steel 15, which are woven into an open-mesh fabric 16, it being understood that the fabrics are woven, with different-sized meshes to suit different purposes.

In placinga screen in position the meshes at the ends-thereof are engaged with pins 17 projecting from the rollers 8, and the rollers are then revolved by means of a crank 18, which may be engaged therewith to stretch the fabric, the latter being supported by the central roller 14. To prevent sagging of the edges of the screen, these edges are engaged in guides 19, attached to the side pieces 6 and When it is desired to remove the screen,

one of the pawls 13 is moved out of engagement with its ratchet-Wheel 12 to removethe tension from the fabric, after which the meshes at one end maybe removed from the pins and the roller at the opposite end revolved by means of the crank 18 to wind the fabric thereon, after which the roller may be removed and another, also carrying a fabric, may be substituted therefor, and the fabric may be connected with the other roller as described.

In practice changes may be made in the specific construction shown and described without departing from the spirit of the invention.

What is claimed is 1. In a separator for threshing-machines, the combination with a frame having slots in one side thereof, of rollers removably and revolubly mounted in the said slots, a foraminous fabric removablyconnected to the rollers, and
