PHILIP M. GUNDLACH, OF BELLEVILLE, ILLINOIS.

GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 536,837, dated March 26, 1895.

Application tiled November 3,1894. Serial No. 527,814. (Model.)

.To a/ZZ whom it may concern.-

Beit known that I, PHI-LIP M. GUNDLACH, a citizen of the United States, residing at Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Grain-Drills.; and I do hereby'declare the following to be a full, clear, and exact description cf the same, reference being had to the accompanying drawings, forming a part of this specification.

rI'his invention relates to that type of grain drills, and the feeding mechanism therefor, that forms the subject matter of my prior Letters Patent, No. 351,047, dated October 19, 1886; and the present improvements have for their objects, first, to provide a simple and effective construction of the individual feed cylinder housings of a grain drill embodying the features of a simple and eflcient construction of the inclined conveyer spout of such housing so that the fed grain'in its passage down through such spout will be y protected from the wind, and a spilling or wasting of such grain prevented; a`V simple interlocking sectional construction of such housing so that the parts will tittogether and interlock without the use of fastening bolts or rivets; and a cheap and durable means for securing the housing parts in their interlocked condition, and which at the same time aords means for supporting the rear end of the carrier chute of the drillflukes, in a pivotal and slidable manner; second, to provide a strong and durable construction of the intermediate chute that connects the grain drill fiuke with the discharge spout of the feed mechanism, and withwhich the passing grain is protected in a very perfect manner from the wind, and at the same time a very strong and substantial sliding and pivotal connection is made between the rear end of such chute and the discharge spout of the feed mechanism; third, to provide a readily removable and reversible gage plate formed of spring metal that is adapted to change the area of the outlet orifice of the feeding mechanism, and thus' gage the amount ofgrain that is fed by the same; fourth, to provide a simple and effective means for securing the cut o plates of the feeding mechanism at their required adjustment. I attain such .objects by theconstruction and arrangements of parts illustrated in the accompanying drawings, in which- Figure 1, is a longitudinal sectional elevation, mainly on line -af, Fig. 2, of an individual feed mechanism and its connections; Fig. 2, a-plan view of the same; Fig. 3, a transverse section at line Fig. l; Fig. 4, a detail elevation of the mechanism for securing the cut off plates of the feeding mechanism at their required adjustment; Fig. 5, a view of the pointer portion thereof, detached; Fig. 6, an end elevation of the out off plate, detached; Fig. 7, a bottom view of the same; Fig. 8, an enlarged end elevation of the removable and reversible gage plate; Fig. 9, a side elevation of the same; Fig. l0, an elevation of the hinged tongue or plate that has bearing against the fiuted periphery of the feed cylinder to retain the grain in the flutes of the same.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, l represents a portion of the bottom of the grain box, on the under side of which are secured the series of grain feed mechanisms by means of their housings 2, as usual. Each housing .2, will consist of two substantially counterpart members having a horizontal plane surface that Iits against the bottom of the seed box yand is provided with the usual opening for the down passage of the seed into the feed mechanism proper, as in my former patented construction, and in the present improved construction each pendent side plate 3, will be formed with an annular shouldered recess 4, to constitute a bearing'for the plain cylindrical ends 5, of the longitudinally fluted feed cylinder 6, so as to support the said cylinder in proper operative position. n

The feed cylinder 6, is of an annular cylindrical form, with its outer surface fluted longitudinally, so as to form grain feeding cavities, its extreme ends 5, being left plain so a's to form bearings as above set forth. At its center it is provided with a spider 7, the hub of which embraces the non-circular operating shaft 8, that is common to the whole series of feeding mechanisms, and is driven in the usual manner by connections wit-h the driving wheels of the grain drill.

IOS

at its upper end in the pendent side plates 3,

tease? and adapted to bear against the lluted periphery of the feed cylinder to hold the grain in the tlutes of the same until the proper point of discharge is reached.

10, is a rearwardly and downwardly projecting spout formed by inwardly deflected portions of the pendent plates, and bya bot tom portion 11. As thus formed the spout 10, will be of a narrowed natu re transversely, the purpose of which will be hereinafter more fully set forth.

12, are inturned lips on the side plates 3, partly cl-osing the top ofthe spout 10, so as to shield the interior of such spout from the wind, and in connection with the narrowed nature of such spout as heretofore described, preventingin a very perfect manner any spilling or wastage of the grain.

13, is a hook on one side plate 3, beneath the spout portion that engages over a lug portion 14, on the other side plate, so as to lock the two plates together against an outward movement away from each other.

15, are eyes at the extreme lower end of the spout portions of the side plates 3, that are adapted to receive a cross pin 16, that is intended to be driven into place, to prevent a movement of the one housing part past the other in a circular direction.

NVith the above improved construction the two housing members are engaged with the bearing ends of the feeding cylinder, and with such cylinder as a fulcrum the side plates are turned circularly until their hook 13 and lug 14, are engaged to prevent lateral disengagement. lVith the hook and

lng

13 and 14 in proper engagement, the eyes 15 on each side plate will be in line to receive the pin 16, that locks the two housing members to` gether against movement one past the other.

By the above improved construction the housing members are substantially secured together in a readily detachable manner Without the use of screws or rivets, and as so constructed admit of the ready casting of the parts without cores and requiring but little if any finishing previous to assemblage together.

The cross pin 16, in addition to its function above described is adapted to project at each side of the eyes 15, to formasupport for the intermediate chute 17, that conducts the grain from the spout 10, into the bottom passage of the grain drill fluke. In the present invention this intermediate chute 17, is formed with reinforced inturned flanges or lips 18, along its top length, that rest upon the outer ends of the cross pin 16, to be supported thereby in a pivotal and slidable manner, so as to admit of the necessary movement of such chtite 17, in the usual movements of the grain drill flukes. This chute is preferably made with straight sides and an angular bottoni, as shown, as best adapted to its present particular uses. Other shapes may however be imparted to such chute without departing from the spirit of my present invention.

19, is the horizontally sliding out olf, for regulating the quantity of grain fed by the feed cylinder 6, and which is guided in its movement byguide lugs 20, on the end plates 3. This cut otT plate is divided into a horizontal table portion 21, that in the adjustment of the cut off plate, changes the area of the opening, down through which the grain passes to the feed cylinder, and an inclined hopper portion 22, that in the aforesaid adjustment of the cut off plate covers more or less of the fluted feed cylinder and affords means in addition to the table portion/2l, for regulating the quantity of grain fed by the tinted feed cylinder. In the present construction the table portion 2l, and the hopper portion 22, of the cut off 19, are connected together by a connecting web 23. In the present construction the web 23, forms one of the walls of a grain containing hopper above the feed cylinder 6, and which has such cylinder as a bottom, and an end plate 3, the portion 22, and a vertical gage plate 24, as the other sides of such hopper.

The vertical gage plate 2l, in the present invention is formed of spring or sheet metal, bent so as to form a flat main portion and a pair of clips 25, that engage the horizontal portion 26, of the main housing 1, to effect an attachment. These spring clips are so positioned with relation to the opposite edges of the gage plate, as to be nearer one edge than the other, so that by a reversal of said plate, a greater or less opening will be formed between the feed cylinder and the adjacent edge of such gage plate.

The series of adjustable cut offs` used in the grain drill will be attached to the usual adjusting bars 27, common to all; and the adjustment of the same and the securing of the same at the required adjustment are effected by the following means:

28, is an index or pointer piece, secured to the bar 27, and provided with a pointertinger 29, raised above the pair of lugs 30.

31, is an index plate secured to the grain box of the drill with its free end arranged between the pointer 29, and the lugs 30.

32, is awedge adapted to be driven between the pointer finger 29, and the plate 31, to firmly clamp the parts together, and secure the sliding cut o of the feeding mechanisms at the required adjustment.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
