Letters Patent No. 112,700, dated March 14, 1871.

IMPROVEMENT IN GRAIN-DRILLS.

The Schedule ref-erred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, SILAS N. GALLUP, of Macedon, county-of Wayne, State of New York, have invented certain new' and useful Improvements in Grain- Drills, of which the following is a full, clear, and exact description," reference being had to the accompanying drawing making part of this specification,`and in which` Figure 1 is a perspective view taken from the under Side of the machine, and

Figure 2 is a vertical sectional view taken through the cogged wheels.

The invention relates to that class of drills or seeding-machines in which the hoes may be arranged in one row or in two rows, (that is, zigzag,) at the will of the operator.

The first part of the invention consists in a novel construction and arrangement of the devices for aetuating the bars to which the drag-bars of the hoes are attached, the object of my improvement being three-fold: first, to dispense with one set lof gears fo r operating the bars;4 second, to furnish a central support for said bars against the backward strain pro` duced by the hoes; and third, to make them mutually lsupport'each other.

'lhe second part ot' the invention consists in mounting the bars in an adjustable frame, by means of which construction the hoes can be moved either forward or backward out of the way when it is desired to sow the grain broadcast. l

The nature of these improvements will be fully understood from the following description.

In vthe drawing- A A represent the longitudinal or side pieces of the frame, uponwhich the hopper and seeding devices of the drill are mounted.

B is the forward transverse girt, to which the tongue is attached. y

C is the tongue, which may be secured to transverse girt B in any usual or desired manner.

D is a sill or base, which, with the end-blocks E, forms a frame-work upon which are snpportedthe bars F G.

Bars F G are mounted upon pivots which turn in suitable bearings in blocks E, (shown in dotted lines centers are coincident with the centers of the pivots e, so that if the wheels are rotated 4in either direction they will remain in mesh with each other, -the arrangement of these parts being fully shown in g. 2.

K is a strap or shell surrounding the two wheels I I', substantially as shown in fig. l, and tit-ting them closely. 7

This strap serves a double purpose: First, it serves g to keep the two cogged wheels I I'always in mesh, as without'it (the strap) the backward strain-upon the rear bar Gr would at times, from the strain of the hoes, withdraw it (cog-wheel I) from the `wheel.1nounted upon bar F. The strap not only keeps the wheels in mesh, but, secondly, it makes the irst bar F assist in supporting the rear one, G, against any unusual strain which may be thrown upon it. f

vThe strap K is rigidly secured to base or sill D, and'i'sthus made to support both bars centrally, independently of one supporting the other, as above described. v

Lis a rod or link attached to one of the *cogged wheels, and so located as to be within convenient reach of the attendant.

The frame-work DE E is mounted upon the tongue and secured thereto by bolts in such manner that it can be moved backward or forward, as the case may be, in orde/r to move the hoes from immediately below the distrihuters when the machine is used for sowing broadcast. l

In using my devices the wheels I I' are operated by the link L to move the free edges of bars F G in opposite directions, carrying with them the drag-bars, thus arranging the hoes in one or more rows, as may" be required.v

' The link L should be locked in position by some of the well-known devices, which it is not necessary to describe here. ,Y

In practice the cogged wheels should be cogged upon such portions oi' their peripheries as shallbe engaged with each other, thus leaving such portions as bear upon the strap K smooth.

.Having now described my invention,

What I claim as new, and desire to secure by Letters Patent, is a l. lhe combination cf cogged wheels I I and strap K with the oscillating bars F G, substantially as set forth 2. In combination with the bars F G and drag-bar H, the movable frame D E E, substantially as set forth.
