GRAlN-DRILL AND SEEDER.

SPECIFICATION forming part. of

Letters Patent No. 369,383, dated September 6, 1887.

Application filed November 27,1886. Serial No. 220,051. (No model.)

To (tZZ whom it may concern.-

Be it known that I, WILLIAM D. Annnrr, of Denver, in the county of Arapahoe and State of Colorado, have invented certain Improvements in Grain'Drills and Seeders, of which the following is a specification.

My invention relates to that class of graindrills and seeding-machines in which the furrow-opening devices are carried by a series of drag-bars jointed to a wheeled frame and arranged to rise and fall independently, and has reference more particularly to improved means for applying downward pressure to said bars.

The improvement is designed for usein connection with those machines in which furrowopening disks are applied, two to each dragbar, as represented, for example, in my applications forLetters Patent of the United States filed, respectively, on the 5th day of April, 1886, Serial No. 199,137, on the 22d day ofMay, 1886, Serial No. 203,029, and on the 30th dayof July,1886, Serial No. 209, 547, but is also'applicahle to machines in which tubular hoes are used in the ordinary manner.

The improvement consists in a peculiar arrangement of weights and equalizing-levers, through which the pressure is applied equally to the several drag-bars, as hereinafter described.

Beferring to the accompanying drawings, Figure 1 is a perspective view illustrating my invention in its most simple form, the weight acting upon two drag-bars. Fig. 2 is a rear elevation of the same, three of the weights being shown, each in connection with two dragbars. Fig. 3 is a side elevation in outline of the machine. Fig. etis a rear elevation showing a single weight used in connection with four drag'bars.

\Vith the exception of the parts hereinafter specifically described, the entire machine may be of ordinary construction. I have omitted from the drawings the hoppers, the feed mechanism, and the various other customary parts which are foreign to my invention.

Referring to the accompanying drawings, A represents the wheeled main frame; B B, the series of drag-bars jointed at their forward ends to the frame, and O O furrow-opening disks, usually applied two to each bar. These parts may be identical with those represented in either of my prior applications.

In applying my improvement in its preferred form I connect to or mount upon the rear end of each drag-bar an upright rod, i), playing at its upper end loosely in a suitable guide on the frame. hen the weight is to be applied to two drag-bars only, I turn the upper ends of the two rods laterally, as shown in Figsl and 3, and by means of links or other connections suspend a bar or lever, E, at its two ends from the respective rods. From the center of this bar I suspend a weight, F, which may be a metal block of suitable size and form, or, as shown in the drawings, a block-like receptacle, into which weights of any suitable character may be placed.

It will be observed that the lever E acts as an equalizing device, distributing the weight between the two rods D, which act with a downward pressure on the drag-bars, allowing each to rise and fall without affecting the other. When a single weight is to be used with four bars, I apply the levers E, as above described, instead of connecting the weight directly to said levers. I employ asccond lever, G, suspended at its ends from the middle of the levers E, and provided at its own middle with the weight F.

I am aware that a single weighted lever has been combined with a series of intermediate levers acting on the forward ends of a series of drag-bars, and this I do not claim.

What I do claim is- 1. In a seeding-machine, a wheeled frame and a series of drag-bars jointed at their forward ends thereto, in combination with a series of upright rods, connected at their lower ends to the respective drag-bars and arranged to slide at their upper ends through guides on the frame, a weight, and an equalizing lever or levers connecting said weight with two or more of the rods, as described.

2. In a seeding-machine, the combination, with the main frame and a series of drag-bars jointed thereto, of the series of equalizin levers connected with the respective dragbars, and a box-like receptacle suspended from said levers and adapted to receive weights, as described and claimed.
