VUNITED STATES PATENT OFFICE.

JOHN M. LEMMON, OF DES MOINES, IOVA.

FLoUR-DREssER.

SPECIFICATION forming part of Letters Patent No. 439,821, dated November 4, 1890.

Application filed June 26, 1890. Serial No. 356,894. (No model.)

To a/ZZ whom ,it may concern.-

Be it known thatV I, JOHN M. LEMMON, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Flour-Dressers; and I do hereby declarethat the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in Hour-dressers, and the novelty7 resides in the. peculiarities of construction and the combinations, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a side elevation of my improved dresser with parts broken away and others in section. Fig. 2 is a vertical cross-section through the same. Fig. 3 is an end View. Fig. 4 is a sectional detail of the bolting devices. Fig. 5 is a detail showing the manner of fastening the cloth. Fig. 6 is a detail of the adjustable slide between the conveyers. Fig. 7 is a cross-section through the same. Fig. 8 is a detail of the boltin g device. Fig. 9 is acrosssection of Fig. 5.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the casin g within which the conveyers and bolting-cloth are arranged. It will be constructed of suitable material and of a size and shape to suit the user.

B are sloping walls which lead to the longitudinal trough or box a, in which are arranged the conveyers C and D, as seen best in Figs. l and 2. These conveyers' may be of any of the approved forms, but preferably consisting each of a polygonal shaft, to which the flights are secured. Between -the two conveyers there is arranged an adjustable slide or slides b, which are movable on the metal guides c, which are held in place by the screws or other means d, and which guides extend into grooves in the edges of the slide, as shown best in Fig. '7. The shafts of the conveyers are extended at one end, as shown in Figs. l and 3, and upon these extended ends are'secured the sprocket-wheels E and F.

Gis an endless sprocket chain passed around one of said sprocket-wheels and engaging the other, as shown in Fig. 3, said chain being passed around the sprocket-wheel e on the extended end of the haft II, as shown in Figs.

l and 3.

I is a feed-spout suitably fsupported at the feed end of the machine, and this spout has its inner end arranged to discharge or feed the material on to the small conveyer J, which is carried by the shaft H, and which conveyer is confined within t-he housing f, secured to the end of the casing, as shown best in Fig. 4. The shaft has a bearing in the casting g, which is formed with sprocket-teeth h, (see Fig. 4,) and which is secured to the shaft by a setscrew i. (See said Fig. 4.) The body portion of this casting is provided with holes j to allow the material to pass out into the interior of the bolting-cloth, as shown in Fig. 4.

K is the lower shaft of the cloth, which is carried in adjustable bearings or boxes k, provided with set-screws, as shown in Fig. 3, by which the shaft may be adjusted to tighten the cloth when necessary. This shaft has a bearing in the casting L, to which it is secured by a set-screw Z, (see Fig. 4,) and which casting is formed with sprocket-teeth m, as shown in the saine figure.

The shaft lI is extended at one end, and carries a band-pulley fn, to which power may be imparted from any suitable source, and from which it is imparted to the bolting-eloth and to the conveyers. i

M is the bolt-ing-cloth of silk, and it is secured in place in the following manner:

N are chains which are designed to engage the sprocket-teeth on the ends of the castings on the shafts of the bolting-cloth, and O are leather bands which are secured to the said chains. i

I are pieces of ticking which are sewed to the bolting-cloth, and the edges of the ticking are turned up and around the ribs or rods p, which are secured at their ends to the chain and extend from end to end of the bolting- IOO cloth to enable it to be better and more securely held thereto and prevent it from dis'- placement. The ticking at the ends of the cloth is laced or otherwise secured to the leather belts. This construction will be vreadily understood from Figs. 5 and 9.

The ticking P extends the whole length of the rods p, and is stitched to the cloth M throughout its entire length by stitches m. (See Fig. 9.)

The operation will be readily understood. The material is fed into the device through the feed-spout and bolted through the cloth, being carried up upon the inner surface of the under side of the same, and as it falls through Vthe meshes thereof it falls into the conveyer-troughs and by means of the con- Veyers carried to one end of the machine,

Where it may be deposited into bags or other` What I claim as new is-4 l. The combination, with the chains, the leather belts secured thereto, thebolting-cloth, the rods secured at their ends to the chains, and the ticking Wrapped around said rods and secured to the bolting-cloth, substantially as speciied.

2. The combination, with the chains, of the leather belts secured thereto, the ticking secured to the ends of the cloth and to the leather belts, the bolting-cloth of silk, the ticking secured thereto, and the rods secured at their ends to the chains and around which the latter ticking is wrapped and secured, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN M. LEMMON.
