IMPROVED eot'rmceman'n.

The Schedule rei'exied to in these Letters Patent and making part ot the same.

To all whom it may concern: I

Be itknown that I, JOHNT. AGNER, of Lexington,

in the county of Rockbridge, and State'of Virginia,

have invented a new and useful Improvement on Boltproved bolting-reel.

Figure 2 is a cross-section through the reel, taken Similar letters of reference indicate corresponding parts in both figures. i i 'The object of my invention is to improve flour-bolts,

' by enclosing the bolting-cloth between internal and external reticulated fenders or guards, in such manner as will effectually exclude those insects whichdestroy the bolting-cloth, aswill be hereinafter explained.

To enable others skilled in the art to understand my invention, 1. will describe its construction and operation. a

In the accompanyingdrawings A A represent two circular heads, one of which, A, has a central opening,'a, through it, through which the material to-be bolted is fed into the bolt, in the usual well-known mariner.

Upon the inner sides of these heads hexagonal pieces 0 c are concentrically secured, the outer edges of which are rabbeted, and have secured to them the longitudinal bars h h. The bars G are secured to the inner edges of said piecesc 'c,.at the angles thereof.

, Between the bars G and h, hexagonal pieces 0 are secured, for stiffening] the bars, and strengt ening them at those points where-the radial arms Q unite with the innermost bars G.

- Arms 0 radiate from a longitudinal shaft, B, passthe reel;

The bolting-cloth 0, indicated in red, figs. 1 and},

is applied, in a suitable'manner, around and secured to the bars 71., and extends from the head A nearly to the head A, as shown in fig. 1. l

Surrounding this cloth 0 is a wire cloth, g, which is secured to the'outer edges of the'bars d, and which extends from one head, A, to the other, A.

Within the space enclosed by the bolting-clothe,

and secured to the outer edges of the bars G, is awire cloth, s, which extends from one head,- A, to the other," A. The-.wire cloth used inside and outside of the bolting-cloth, should not be of such a degree of fineness as to interfere with the free passage through it of the material which is being bolted, nor should its meshes be so large as would allow the passage through it of insects which destroy the bolting-cloth.

It will be seen that I completely enclose the bolting cloth e between wire fenders, which will prevent b'ugsj from obtainingaecess to it. At the same time I do not impair the bolting-capacity of the cloth, but, on the contrary the interior reticulated. fender, or wire cloth swill retard the passage through'it of the coarsest portions of the substances which are fed into the bolt, and thus prevent these substances from clogging the fine interstices through thebolting-eloth.

The advantage of my improvement will be apparent, when I state that a bolting-cloth which costs from fifty to one hundred dollars, is frequently rendered useless by the ravages of insects which feed on the flour, and which willdestroy a cloth in a very short time, whether the bolt is in operation or at rest, if it is not protected as I have above described.
