DRILL.

SPECIFICATION forming part of Letters Patent No. 294,603, dated March 4, 1884.

- Application filed August-6, 1883. (No model.) i

To all whom it may concern:

Be it known that we, MOSES F. FOLEY and THOMAS A. FOLEY, both of Waveland', in the county of Montgomery and State of Indiana,

' have invented certain new and useful Im-' a side and rear elevation of a standard, illustrating the attachment of the plow.

The object of this invention is to provide grain-drills constructed in such a manner as to adapt them for use in drilling wheat between rows'of corn.

The invention relates to a grain-drill constructed with curved brackets having lugs upon their outer ends to receive the rear ends of the side beams, and bearings in their inner ends to receive the journals of the drive-wheel and drive-shaft, so that the said beams, wheel, and shaft will be firmly connected. The plowbeams are made withholes to receive the lower ends of the seed conducting'tubes, and with lugs upon their lower side to receive the bolts and the break-pins that connect the said lugs with lugs upon the upper ends of the plowstandards, so that the said tubes, standards, and beams can be conveniently connected. The central or draft beam is split at a little distance from its rear end, with which the plow-standard and conducting-tube are connected, to form projecting supports for the attachment of the forward ends of the side beams. The plow is .secured to a plate, which is hinged at itslower end to the standard by lugs and a bolt, and is connected at its upper end with the said standard by lugs and a break-pin, so that the said plow, when it strikes an obstruction, can swing to the rear ward, as will be hereinafter fully described.

A represents the center beam, the forward end of which projects to serve as adraw-beam.

The center beam, A, at a little distance from its rear end, is split and is spread, as shown in Fig. 3, to form supports for the forward ends of the side beams, B, which are secured in place by bolts 0. Asthe beams B pass back from the beam A, they are bent outward, rearward, inward, and rearward, to bring the rear ends of the said beams into proper position to receive the ends of the brackets D, which are secured in place by bolts E. The brackets D are held from turning upon the bolts E, and are strengthened in position by lugs F, formed upon the outer sides of the end parts of the said brackets, and overlapping the upper and lower sides of the rear ends of the beams B. The brackets D are made in U form, with their inner arms longer than their outer arms, as shown inFig. 2, and in theends of the said inner arms are formed bearings. for the journals of the drive-wheel G.

To the beams 13 A B are attached the lower ends of three uprights,'H, the upper ends of which are attached to the bottom of the seedbox I, to support the said seed-box above the small cylinders K, having recesses formed in them to receive seed and remove it from the seed-box. The seed-dropping cylinders K are attached to a shaft, L, which revolves in bearings attached to the bottom of the seed-box I, and which has a beveled-gear wheel, M, placed upon it. The teeth of the gear-wheel M mesh into the teeth of a beveled-gear wheel, N, attached to the shaft 0, the upper end of which revolves in a bearing, 1?, attached to the seedbox I. The lower end of the drive-shaft 0 revolves in a socket-bearing, Q, formed-in the lower end of one of the brackets D.

To the drive-shaft 0, near its lower end, is attached a beveled-gear wheel, R, the teeth of which mesh into the teeth of the beveled-gear 9 5 wheel S, formed upon or attached to the drivewheel G, so that the cylinders K will be revolved to scatter the seed by the revolution of the said drive-wheel.

The hub of the gear-whee1 M is made long, r00

and has an annular groove formed in it to re ceive the inwardly-bent forked lower end of the lever T, which is fulcrumed to the rear side of the seed-box I by a bolt or other suitable means. The upper part of the lever T projects upward at the rear side of the seed box I, so that the seed-dropping mechanism can be readily thrown into and out of gear by operating the said lever T. The lever T can be held in either position by a toothed bar or other suitable catch attached to the seed-box I, but which is not shown in the drawings.

The seed is kept from escaping at the upper rear sides of the cylinders K by cut-off plates U, attached to the inner surface of the rear side of the seed-box I, as shown in Figs. 1 and 3.

The seed-dropping cylinders K are covered by guards V, attached to the bottom of the seed-box I, to prevent the seed from scattering as it falls from the recesses of the said cylinders. The guards Y can also serve as bearings for the shaft L, and have openings V in their rear sides, to allow the driver to see if the said cylinders are operating properly. The guards V are provided with discharge-nozzles Y which enter the upper ends of the tubes \V. The lower ends of the tubes W enter holes X in the laterally-projecting parts of the side beams, B, and in the rear end of the center beam, A, so that the conducting-tubes W will be supported by the said beams. From the holes X the seed drops into the interior of the hollow standards Y, through which it passes into the channels opened by the plows formed upon or attached to the lower ends of the said standards. The standards Y may be made open at the lower part of their rear sides, as shown in Fig. 2.

Upon the front and rear sides of the upper ends of the standards Y are formed pairs of lugs Z, to receive between them the lugs a, formed upon or attached to the lower sides of the beams B A B, in front and rear of the holes X. The rear lugs Z a are connected byabolt,

- b, and the forward lugs Z a are connected by a wooden pin, 0, of sufficient strength to support the draft-strain under ordinary circumstances, but which, should the plow strike an obstruction, will break and allow the said standard to swing back, to prevent the said plow from being broken.

In the construction illustrated in Fig. 5 the plow d is secured, by bolts or rivets or other suitable means, to a metal plate, 0, which is fitted to the forward side of the lower end of the standard Y. Upon the side edges of the lower end of the plate 0 are formed lugs f,

which are perforated to receive the bolt 1 The bolt 9 passes through the lugs f, and through the lower end of the standard Y, so that the said plate and plow will be hinged to the said standard by the lugs f and bolt g.

Upon the upper ends of the side edges of the plate a are formed lugs h, which are made of such a length as to project beyond the rear side of the said standard, and are perforated to receive the wooden pin 6, which crosses the rear side of the said standard, as shown in Fig. 5. The wooden pin i is made of sufiicient strength to sustain the draft-strain under ordinary circumstances, but will break shouldthe plow strike an obstruction, and allow the plow d and the plate e to swing back upon the bolt 9, and thus prevent the plow from being broken.

j is-a plate which slides in guides attached to the bottom of the seed-box I, and has perforations formed in it corresponding with the discharge-openings I of the seed-box bottom, so that the said plate can be adjusted to regulate the size of the said discharge-openings or to close them entirely, as may be required. Upon the rear edge of the gage-plate is formed an arm, k, which is bent upward at the rear edge of the bottom of the seed-box I, and is widened to extend along the said rear edge. The widened upwardly-projecting part of the arm 76 is slotted to receive the screw 1, that is screwed into the rear edge of the seed-box bottom, to secure the gage-plate j in place, and to limit the movement of the said gageplate j. The arm is is provided with an index, m, which moves along the rear side of the seed-box I and shows the position of the gageplate j. The arm is also provided with a handle, a, for convenience in adjusting the gage-plate 7'..

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. The combination of the median beam, A, split and spread apart as shown, the bent side beams, B B, bolted at their front ends to the spread part of beam A, and the brackets DD, to support all parts of the drill on a median rear wheel, as shown and described.

2. The combination, with the beams 13, of 4 the brackets D, provided with lugs F, overlapping the upper and lower sides of said beams, as shown and described.
