DISTRIBUTER FOR GRAlN-SEPARATORS.

Patented April 30, 1907.

Application filed March 1. 1906. sci-in 110. 303,659.

To all whom it may concern.-

Be it known that I, i\iALCOLM L. BARBEAU,

a subject of the King of England, residing at Silver Creek, in the county of Chautauqua and State of New York, have invented a new and useful Improvement in Distributors for Grain-Separators, of which the following is a specification.

This invention relates to a distributor for I0 grain separating or grading machines.

In machines of this character two or more shaking shoes are usually mounted in .the same frame for obtaining the desired capacity, which shoes are reciprocated in opposite directions so as to neutralize the arring effect upon the machine and cause the same to run more steady and less noisy. Considerable difficulty has heretofore been experienced in supplying the screens of these the same source which lack of uniformity caused not only unbalancing and racking of the machine but also produced a difference in the separating effect of the screens of the several shoes.

The object of this invention is the provi sion of a device which will distribute the grain from the same source to different separator screens with absolute uniformity or 3 equality so as to avoid the above mentioned objections.

In the accompanying drawings consisting of three sheets: Figure 1 is a fragmentary vertical longitudinal section of a grain separator or grader equipped with my improved distributor the section of the latter part being taken in line 11, Fig. 2. Fig. 2 is a horizontal section on an enlarged scale, taken in line 22, Fig. 1. Fig. 3 is a fragmentary 4 front elevation of the distributor and one of the side walls of the adjacent shoe in section. Fig. 4 is a vertical cross section in line 4 4, Fig. 2. Fig. 5 is a fragmentary vertical longitudinal section of the machine in line 55, Fig. 2, on the same scale as Fig. 1. Fig. 6 is a fragmentary perspective view of the distributer. Fig. 7 is a sectional view similar to Fig. 1 showing a modified construction of the distributer. Fig. 8 is a horizontal sec- 5 tion in line 8S, Fig. 7. Fig. 9 is a fragmentary sectional view showing the distributer organized for supplying two pairs of shoes with an equal amount of grain from screens. Fig. 10 is a horizontal section in line 10-10, Fig. 9.

Similar letters of reference indicate corresponding parts throughout the several views.

Referring to Figs. 1 to 5, A represents the main frame of the grain separator or grader which may be of any suitable construction to support the working parts of the machine.

B represents an upper shaking shoe and B a lower shaking shoe arranged below the upper shoe. These shoes are so mounted and operated that the same are reciprocated horizontally in opposite directions. The means for thus supporting and operating these shoes may comprise flexible hangers a and rotary eccentrics a such as are commonly used and well known for this purpose.

C, C represent the screens which are mounted in a forwardly inclined position in the upper and lower shaking shoes. The rear walls I), l) of the upper and lower shoes are substantially in line and the rear end of the upper and lower screens are also ar ranged in the same relation or nearly so. The space between the rear end of the lower screen and the adjacent rear wall l) of the lower shoe is bridged by a feed board D. The grain which is to be separated by the screenZSo of the lower shoe is deposited or dropped from above upon the feed board D and directed by the same forwardly over the lower screen.

E represents an upright partition or wall arranged transversely in the upper shoe between its rear wall I) and the rear end of the upper screen. Between this partition and the rear end of the upper screen is arranged a comparatively narrow feed board (Z. The grain which is to be separated by the upper screen is delivered from above upon the feed board (I and directed therebyforwardly over the upper screen. Between the partition E and the rear wall of the upper shoe is arranged the distributor which receives the grain and delivers the same in equal parts to the upper and lower screens and which is constructed as follows:

F represents a distributing box arranged between the upper end of the partition E and the rear wall of the upper shoe and having a closed bottom f and an open top through which the grain to be separated is delivered into the distributing box. A plurality of long discharge spouts forming one set are arranged transversely side by side at the front side or wall f of the distributing box and communicate at their rear ends with the box through openings 9 in said front wall while their front ends open forwardly, as shown at g. Each of these spouts has a bottom 9 forming a forward extension of the bottom of the distributing box, two upright side walls 9 9 arranged at the opposite longitudinal edges of the spout bottom and a top wall 9 extending forwardly from the upper edge of the respective opening 9 and across the upper ends of the side walls. 9 Between the long spouts the front wall of the distributing box is provided alternately with a plurality of discharge openings h. Top walls 71/ extend forwardly from the front wall f of the distributing box at the upper edges of the openings h, and upright walls 71/ extend downwardly from the front ends of the top walls h. The top and end walls h, 72/ adjacent to each opening it bridge the space between the upright walls" g of the two adjacent long spouts and form with the latter a short discharge spout the outlet opening or hole h of which is in the bottom thereof between the lower edge of its upright front wall 7L2 and the front edge of the bottom of the distributing box. The latter is so arranged that the long discharge spouts are arranged above the upper end of the upright partition E and discharge the grain forwardly beyond the same and the front wall 7L2 of the short spouts are arranged in rear of said partition so that the latter discharge the grain downwardly in rear ofthis partition. The tops gtand h of the long and short spouts are preferably made continuous out of the same piece, as shown.

The area of the two sets of short and long spouts and the openings or spaces whereby the same communicate with the distributing box is the same. It follows from this construction that the stream of grain which. flows from the distributing box through the long and short spouts is divided into two perfectly equal parts. One of these parts is directed by the long spouts upon the feed board of the upper screen and the other part is directed by the short spouts upon the feed board of the lower screen. I is preferably mounted on the upper shoe between the partition E and the rear wall thereof and has its upper end below -the outlet ends of the short spouts while its lower end is arranged over the feed board of the lower screen. This chute serves to conduct and control the grain in its passage from the short spouts to the feed board of the lower screen and prevent scattering or irregular delivery of the same to the lower screen.

For the purpose of enabling the speed with Which the grain moves from the distributing A vertical chute box to its spouts to be regulated according to the character of the grain which is being separated or other conditions means are provided whereby the distributing box and its discharge spouts may be tilted more or less. The means for this purpose shown in the drawings consist in pivotally connecting the distributer on its under side at its front end by a hinge with the upper end of the partition E so that he distributing box may be raised more or less at is rear end. As shown in Fig. 1, the rear end of the distributing box is arranged lower than its front end. In this position of the distribu'er the grain is compelled to move upwardly from its rear or receiving end to its front or discharge end whereby the de ivery or feeding movement of the grain is retarded. If the rear end of the distributing box is raised above its front end the flow of the grain from the same will be accelerated. By this means the distributing box may be adjusted to bring its bottom at the desired angle which is best suited for distributing the particular kind or quality of the material which is to be separated. Any suit able means may be employed for holding the distributing box in its adjusted position, that shown in the drawings consisting of a thumb screw or bolt K secured to an end wall of the distributingbox and passing through a segmental slot 7c in the adjacent side wall of the upper shoe.

As shown in the drawings means are provided for :emoving large particles, such as sticks and straw, from the grain bef ore delivering the latter into the distributing box as is commonly done in machines of this character. This preliminary separator consists of a rcalping screen L arranged on the upper part of the upper shaking shoe, asupply spout Z mounted on the main frame and operating to deliver the mixed grain upon the head of the scalping screen and a chute m arranged upon the upper shoe underneath the scalping screen and operating to conduct he mixed grain which passes through the latter into the distributing box.

Instead of mounting the distributing box and its discharge spouts on the shaking shoe so as to be capable of adjustment at different angles, as shown in Fig. 1, the same may be secured in a fixed position on the upper shaking shoe, as shown in Figs. 7 and 8. lVhen the last mentioned construction is employed the bottom of the distributing box F and of the long discharge spouts are arranged hori Zontal or nearly so that the material is propelled from the rear to the front end of the same solely by the vibrations of the shaking shoe and without producing any retarding or accelerating effect on the movement of the grain.

In Figs. 9 and 10 is shown a construction o the distributing device in which two pairs of screens C C C C are supplied from a single distributing box In this construction the elevated ends of the two pairs of screens are opposite each other and the upper screens 0 C, of both pairs are preferably reciprocated together and in the opposite direction of the lower screens C" C of both pairs. The distributing box in such a construction is wide enough to accommodate sufficient grain for supplying four screens and is provided on both of its longitudinal sides or walls-Pf with alternating long and short spouts G, H which are constructed and operate in the same manner as those heretofore described.

It is immaterial for the purpose of my invention whether the screens and distributer shake in any particular direction or whether the distributer moves with or independent of the screens.

In the constructions shown in Figs. 1 and 5 the screens reciprocate horizontally and the distributer moves with the upper screen.

In the construction shown in Fig. 9, the distributer is disconnected from the screens and may be shaken by any suitable means independent of the screens, for instance an eccentric a I claim as my invention 1.
