' IMPROVEMENT IN FANNING-MILLS,

Specification forming part of Letters Patent No. 46,3l2, dated February 7, 1865.

To all whom it may concern Be it known that I, HENRY W. VEREGGE, of Richmond, in the county of Wayne and State of Indiana, have invented a new and use ful improvement in the manner of hanging the slides or wind-hole shutters of fanning and other wind mills; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making apart of this specification, in which- Figure 1 represents the side of a fanningmill. Fig. 2 represents a vertical transverse section through the same, taken at the red line .70 w of Fig. 1.

Similar letters of reference, where they occur in the separate figures, denote like parts in both.

The slides or wind-hole shutters of fanningmills are generally hung in grooves made in or by two horizontal pieces,one at the top and the other at the bottom of the shutter. This mode of hanging the shutters is objectionable on several accounts-first, the accumulation of dirt, grit, &c., in the grooves prevents them from sliding freely; second, if made to slide freely originally, they will not remain at any fixed position without fastening them, the jar of the machine moving them one way or the other; and, thirdly, if made to Work close, then the least swelling or warping of the wood so binds them as to prevent them from moving at all. I am aware that to obviate these objections to this general plan of hanging the slides holes have been bored through the shutters horizontally, for the reception of a rod or bar, upon which the'shutter may be slid. Though this answers a good purpose, it is difficult and expensive to make and repair, for unless the rod or bar be heavy enough to sustain the shutters without sagging, which of course involves the making of the shutters thick enough for the necessary hole to slide over the bars, it will not work well and smoothly. Besides, with this round bearing there is nothing to keep the shutters close up to the side of the machine and make them what they are designed to be-namely, wind hole shutters.

I make no reference to that kind of shutters that swing from a pivoted point, as they will not open the whole windway when necessary, and do not come within the scope of my invention.

My invention consists in making a horizontal groove in a piece attached to the side or frame of the fanning or other wind mill, and making a strip, rib, or batten on the'slides or shutters that will freely move in said groove, so that the slides or shutters are suspended by the strip or rib, and are kept in place close up to the side of the mill by the piece on which it moves.

To enable others skilled in the art to make and use my invention, I will proceed to dc= scribe the same with reference to the drawlngs.

A represents one of the sides of an ordinary fanning-mill; and B, theopenings thereof, leading into the fan or fan-case, for supplying the fan with air to make a regulated blast.

O O are the slides or shutters for par tiall y or entirely closing the openings B, as may be found necessary. These shutters or 'slides I hang as follows: In the piece D, I

form a groove, a, (rectangular or otherwise,) in that face of it next to the side A of the mill, and upon the shutters or slides G, I fasten a strip, rib, or batten, c, that will freely move in and through said groove a. This strip, rib, tongue, or batten may be as long as the shutters have width, or they may be blocks or cleats, but so made as to run in the the groove, and with rigidity enough to hold up the shutters or slides, which, moving between the piece D and the side A, is kept in proper position as it is moved along. This device is cheaply made and easily attached, and any farmer may easily and readily repair it. The groove a, being horizontal instead of vertical, catches no dirt or grit to clog the movement of the slides. The slides move freely and easily, yet will remain in any adjusted position within the limits of their movement. If desirable, the groove may be dovetailed, and the tongue or piece or pieces that slide in it may be of a corresponding shape or form; 4

Having [thus fully described my'invention and shown wherein it differs from what has ters and a horizontal groove or grooves in the been hitherto known for a similar puspose, face of said frame or piece, as and for the purwhat I claim therein as new, and desire to sepose set forth. cure by Letters Patent, is-- Hanging the slides or shutters 0f fanning or other similar mills t0 the frame, or to a Vituesses: piece connected to the frame, by means of a LEWIS D. STUBBs, tongue, strip, or block on said slides or shut- WILLIAM: BARR.
