VILLIAM WV. HUNTLEY, OF SILVEROREEK, NEWY YORK, ASSIGNOR TO THE HUNTLEY MANUFACTURING COMPANY, OF SILVEROREEK, NEV YORK.

GRAIN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 766,623, dated August 2, 1904.

Application filed December 27, 1898. Serial No. 700,361. (No model.)

.T LM whom it may concern:

Be it known that I, NVILLIAM IV. HUNTLEY, a citizen of the United States, residing' at Silvercreek, in the county of Chautauqua and State of New York, have invented new and useful Improvements in Grain-Separators, of which the following is a specification.

This invention relates principally to a g'rainseparator in which the screens are arrang'ed 1o in zigzag' fashion one below the other and in which the grain flows by gravity from one screen to the other.

One of the objects of my invention is to produce a screen which is simple and durable in construction and which is not liable to become clogg'ed.

Another object of my invention is to provide a feed device whereby the g'rain is distributed uniformly over the entire width of 2o the screens and which is operated by the g'rain flowing through the apparatus.

In the accompanying drawings, consisting of two sheets, Figure l is a front elevation, partly in section, of my improved grain-separator. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a horizontal scction thereof in line 3 8, Fig. 2. Fig. el is a fragmentary longitudinal section of one of the screens and its supports on an enlarged scale.

3o Fig. 5 is a horizontal section of the same.

Fig. 6 is a cross-section in line 6 6, Fig. 5.

Like letters of reference refer to like parts in the several figures.

The main inclosing' case of the separator 3 5 consists of two side walls A A, a front wall A', a rear wall A2, and a top board A, having an inlet a for the grain or other material to be separated. The upper part of the case is contracted and forms a feed-hopper B, the

4o bottom of which is formed by two boards fr', which incline inwardly from the front and rear walls of the case, respectively, and which are separated at their lower ends by a discharge-opening' b2 4 5 C O U O3 C* represent five screens arranged in zigzag' fashion one below the other within the casing. Each of the screens is supported at its upper end in a transverse g'uide (l, arranged on the inner end of a guide-board d,

which inclines inwardly from the adjacent end 5o wall of the casing', and its lower end is supported by a transverse guide (Z2, supported from the side walls of the casing'. ln the a1'- rangement of the screens shown in the drawings the material passes from the feed-hopper 5 5 upon the head of the uppermost screen O and the coarse portion of the material passes from the tail or lower end of the screen upon a delivery-board e and is conducted by the latter through an opening' e in the front wall. The 6o tine material passing through the uppermost screen is conducted by a deiiecting-plate f upon the head of the second screen C, and from the latter the grain passes successively over the remaining screens, the material passing from the tail or lower end of each screen to the head of the screen next below. The material passing' through each of the lower screens O C2 O3 O'L is conducted by a deflecting-plate G through an opening g in the ad- 7o jacent front or rear wall of the casing. The material passing over the tail or rear end of the lowermost screen O" is preferably discharged by a plate y' through an opening' g2 in the front wall of thc casing.

Each of the screens is constructed as follows: H represents a number of straight thin bars or strips, pre fcrably of sheet metal, which are arranged vertically or on edge and lengthwise side by side and are separated from each 8o other to form narrow longitudinal slits or spaces between the strips. The upper edge of each strip is folded or doubled over, as shown at il, to stiffen the strip and also to make the strip thicker along its upper long'i- 85 tudinal portion than along its lower portion, thereby forming a space between adjacent strips which is narrow at the top and wide at the bottom. This enables any material which enters between the upper thick portions of 9o adjacent strips to freely escape through the wider space between the lower portions of the strips, thereby preventing' clogging' of the screen. The screen bars or strips are supported by front and rear tie or supporting bars or rods /1/ lf, which pass transversely through openings formed in the front and rear ends of the strips and through side bars l l',

The screen strips are separated the desired distance by means of washers or spacing-- sleeves L3, which are mounted on the tie-rods between the strips. The screen strips, washers, and side bars aie tightly drawn together bythe head or shoulder on one end of each tie-rod (shown by dotted lines in Fig. 5) and a screw-nut It* upon the opposite end of the tie-rod. In order to hold the screen strips rigidly in their spaced position at the headof the screen, the tie-rod and spacing-washers at the head of the screen are arranged closely to the upper edge of the strips, as shown in Fig. 4:, thereby preventing the strips from being bent or deflected at that point. In order to prevent kernels or particles which project downwardly into the space between the strips from lodging against the spacing-washers at the tail end of the screen, these washers and the tie-rod supporting the saine are arranged -as low as possible on the screen strips, as

shown in Fig. 4, so that the material tailing off from the screen clears the same.

In order to prevent the material from lodging in the space between each outermost strip and the adjacent strip, each side bar is pro-v vided on its inner side with a guard-ange or rib z, which overhangs the outermost pair of strips on the adjacent side of the screen, as

shown in Figs. 5 and 6.

The screen is seated with its side bars in slots or openings -J J' in the side walls of the casing, through one of which the screen may be removed for cleaning or making repairs. The joints between the side bars and the casing are covered by cleats jj', one of which, j, is preferably secured to the casing, while the other is secured to the opposite side bar, which is arranged in the openingfthrough which the screen is removed. The screen may be held in the casing by any suitable means-for instance, by a turn-button lu, arranged on the casing and engaging with the outer side of the cleat j", as shown in Figs. 5 and 6.

As the material passes from the feed-hopper to the screen the same is distributed uniformly over the entire width of thescreens by a feeding device which is constructed as follows: L represents a regulating valve or gate, and M a distributing-plate,both arranged below the opening in the hopper and whereby the flow of the grain from the hopper is regulated and distributed. rlhe regulating-valve is secured with its Lipper end to a transverse rockshaft l, which is j ournaled in the side walls adjacent to the lower end of the front bottom board of the hopper, so as to turn in a vertical plane. The distributing-plate is secured. at its upper end to a transverse rock-shaft m, which is arranged adjacent to the lower end of the rear bottom board Z1 of the hopper and journaled in bearings in the side walls. The distributingplate is arranged substantially at right angles to the regulating-valve, and the lower edge of the plate faces the inner side of the valve. By vibrating the plate the grain is agitated and caused to flow in a stream of uniform width and thickness from the hopper through the space between the plateand regulatingvalve, thereby preventing bridging or lodgwhich is distinct from the separatorV the power exerted by the grain or other material flowing through the separator is utilized for actuating the distributing-plate. For this purpose the flowing grain is directed against the wings fn. of a rotary wheel N, whereby the latter is turned and the movement of this wheel is transmitted to the distributing-plate. As shown in the drawings, theA wheel is arranged in front of the casing and below the outlet g2 for the material which tails off from the lowermost screen C4, so that this material strikes the blades of the wheel with great force by reason of the momentum which the material has gathered in flowing over the screens and turns the wheel, which latter can be of comparatively small diameter. The horizontal shaft of this wheel is journaled in the side walls of a housing O, which incloses the wheel, said housing being connected at its upper end by a chute O with the outlet of the lowermost screen Ci and having an opening in its bottom for the discharge of the material after the same has engaged the drivingwheel and turned the saine.

The motion may be transmitted from the wheel to the distributing-plate by any suitable mechanism, that shown in the drawings consisting of a rock-lever P, pivoted to the outer side of the casing and having one of its arms connected by a rod p with a crank p on the wheel-shaft, and a rock-arm q, arranged on one end of the shaft of the distributingplate and connected with the other arm of the rock-lever by a slot Q and a pin g2 or otherwise.

By adjusting the regulating-valve toward or from the end of the distributing-plate the thickness of the stream of grain, and consequently the quantity of grain, passing from,
