PHILIP M. GUNDLACH, OF BELLEVILLE, ILLINOIS.

GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 351,047, dated October 19, 1886.

(No model.)

To allVV whom it may concern.:

Be it known that l, PHILIP M. GUNDLAei-r, a citizen of the United States, and a resident of Belleville, in the county of St. Clair and State of Illinois, have invented certain new useful Improvements in Grain-Drills, of which the following is a specification.

My invention consists, rst, in the provision of a removable frame to which supplementary ilukes are attached, so that they can be detached from the machine when they are not required, and which frame can be used to receive one set of the main iiuhes in setting them zigzag; second, in the combination, with the half-hooks to which the drag-bars are attached, of a pivoted locking plate or latch for holding the parts in engagement, as will hereinafter more fully appear, third, in the provision of the thimble-skein formed with open-ended slots instead of holes, the purpose being to avoid the use of cores in casting, as will hereinafter more fully appear.

In the drawings, Figure l is a vertical section of the grain-drill, showing the general arrangement of parts. Fig. 2 is a transverse section illustrating the mode of adjusting the vertical cut-off plate. Fig. 3 is a plan view, and Fig. l a perspective view, of the thimble-skein. Fig. 5 is a detail side elevation of the grain-feeding device. Fig. G is a detail plan of same. Fig. 7 is a detail side View of the hinged plate or tongue. Fig. S is a detail front view of the same. Fig. 9 is a detail view illustrating thelatch mechanism,.&c., for holding the drag-bars in position upon their halfhooks. Fig. l() is a detail side view of the feed-cylinder.

A represents the grain-box, supported on a suitable frame mounted on wheels, in the usual manner, and having attached to its bottom a series of independent housings or bearings, B, for the feed-cylinders C, which are operated by a single transverse shaft, o, that receives its motion from a set of gearing (not shown) operated by one of the ground-wheels. The motion communicated to the feedcylinders is i a forward one, so that the feed will be an overshot7 one instead of an undershot, as usual to ordinary grain-drills. The graingrooves c in the feed-cylinder are made straight or parallel with the axis of the cylinder, so that in connection with the bevel or sloping ended tongue e2 the action will be to discharge the grain in a gradual manner. The bevel'or sloping ended tongue or plate cL is pivoted in the housing B and rests against the forward face of the feed-eyliinler, the purpose being to hold the grain in the grain-grooves untily the proper time to discharge the same.

c is a horizontallysliding cut-off plate for regulating the amount of grain fed by the feedcylinder. This cutoff plate is arranged immediately over the feed-cylinder and between it and the feedopening. The advantage of this construction is that .it permits the cutoff plate c3 to be made stationary and obviatcs the necessity of the turning of t-hc .same with the feedcyliuder, which is a very objectionable feature in the ordinary cut-offs used in graindrills.

D are vertically-sliding plates arranged at each seed-opening, for the purpose of adjusting the seedopening to suit different 'sizes oi' grain, and also to regulate the quantity discharged, when desired. These plates are vertically-adj ustable in the following manner:

Df is a horizontally-sliding plate, provided with a series of inclined slots, d, which receive pins or studs il upon the plate D, so that by a horizontal movement of the plate Dby its operating-lever D"' all the vertical plates D will be equally and simultaneously adjusted.

E are a set ot' supplemental iiukes arranged between the main dukes E', and attached to a frame, F, made removable from the main frame of the drill, the object being to allow the supplemental iukes E and frame F to be detached from the drill-frame when not required for use.

rlhe frame F is provided with a sufficient number of attaching-hooks to permit of each alternate one of the main lukes E being attached to it by their drag-bars in setting to a zigzag.

rlhe mode of attachment ofthe drag-bars E2 of the iiukes, so as to render them readily removable, is as follows:

care a series of half hooks or staples, having their pivots e pointing in one direction, so that the forked portion of the drag-bars can be readily slipped onto and off them. When in engagement, the parts are locked in position by a'pivoted latch or dog, c2, in manner clearly indicated in Fig. 9.

ICC

G is the thimlole-skein, formed with ears g, as usual, for attachment to the frame of the drill, and these ears', instead of having holes for the attaching strap or bolts, are provided 5 with open-ended slots g, arranged in. reversed of such combinations, broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. In a grain-drill, the removable frame F,

detachably secured to the main frame of a grain-drill, and provided with a series of supplementary iiukes to lie between the main dukes of the drill, essentially as and for. the

l purpose set forth.

2. In a grain-drill, the combination of the drag-bar El with the half hooks or staples e and lockingllatch e?, substantially as described, and for the purpose set forth.V

3. The thinible-skein G, having attachinglugs g, provided with open-ended slots g', as

described, and for the purpose set forth.

In testimony whereof witness my hand at Belleville, Illinois, the 27th day of August, 1881. f

In presence of- M. F. SIEFERT, GUs'rAvUs NEUMANN.'
