SPEGIFICATION forming part of Letters Patent No. $61,292, dated October 13, 1891. Application filed August 6, 1891. Serial No. 401,866- (Nomodeld To all whom it ma concern: I

Be it known that we, DANIEL 0. Wm BRUNT and WILLARD A. VAN BRUNT, of'Horicon, in the county of Dodge and State of Wisconsin,

and useful .Improvements in Grain-Drills; and we do hereby -.declarethe following tobe a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

= Our invention relates .to animprovement in grain-drills, the ob ect of the same being to provide devices for readily and quickly changing the angle of thecutting-edge of the shoe or runner without stopping and it consists, .broadly, in devices for tilting or inclination of the shoes, independently of the lifting devices.

In the accompanying drawings, Figurel is a view in side elevation of a drill embodying ourinventron.

Fig. 2 is a similar view of a modified form of same, and Figs. 3, 4, 5, 6, 7, 8, 9, 10, and 11 are views of modifications.

A represents the frame of the machine, mounted on wheels B and provided with hopper 0, which latter discharges grain in drills in the usual manner.

area series of drag-bars D, pivotally secured at their front ends to the frame and attached at their rear ends to the shoes or cutters E' at or near the rear ends of the latter. The shoes or cutters E are rigidly secured attheir front ends to the drag-bars D by the braces groundby the springs G.

Fromthe foregoing it will be seen that the inclination of the shoe or cutter is dependent on the position of thefronte'nd'of the frame A. If the front end of the frame be elevated, the front ends of the shoes or runners will also be elevated, and hence in a betterposition to ride more easily over the soil and over any accumulation of trash in its path.

' Ordinarily the tongue H is rigidly secured to the frame and is carried by the team,

Hence there is no provision for changing the relative position of the tongue and the front end of frame A, and hence no provision for changing the angle or inclination'of the shoes or runners. In order to accomplish this the team;

are not, however, essential to-the operation point in advance of itsrear end to the front end I of the frame and provide the rear end of said tongue with a toothed sector a and bell-crank lover I), the latter being pivoted to the tongue concentric with the arc of the toothed sector and provided with a latch for engaging the teeth of the sector and means for disengaging the same from the teeth. The short arin 1 of the bell-crank lever is connected to frame A by link 0, and hence it follows that when the longarm of the lever is pushed forwardly the rear end of the tongue is depressed and the frontend of the frame A,and necessarily thefront ends of the shoes or runners, elevated. By moving the lever in the opposite direct-ion the movements of the parts are the reverse. This movement of theparts is accomplished independently of the devices employed for lifting the parts, and hence does not afiect in the slightest the feed of the The same result can be accomplished by the mechanism shown in Fig. 2. In this device the tongue is pivoted'to the frame at its rear end, and thesegm'ent and bell-crank lever are located over the forward end of frame A.

By the mechanism above described, Wecan change the angle of the shoes or runners to meet the conditions of the soil, and this without any delay and without stopping the team.

As an example, trash gathered in front of the runners or shoes .could be passed over without lifting; the shoes 'or runners by simplymoving the tilting-leven'thus giving the shoes or runners an angle best adapted to ride over the trash. Then, as soon as the obstruction has been cleared, they can be'returned to their" original position or a position where best results can be obtained.

In the two figures of drawings. above 're-. ferred to we h'aveshown the shoe connectedto Drag-bars ofour device, as the shoes can, besecured at their front end to the frame, as shown in Figs.

4, 5,6, 7, and 8, to be hereinafter referred to.

Nor are pressure-springs essential, as our in-' vention comprehends, broadly,n1eans for adjustingthe pole and the frame carrying the porting the frame carrying the hopper and shoes,-whereas in Fig. 9 we have shown our improvement applied to a drill in which the ground-wheels and main axle are connected to and carry a separate frame from the one to which the shoes and hopper are attached I and in the rear thereof.

- In Figs. 3, 4., 5, 0, 7, and 8 nothing but the parts material to our invention are disclosed. In- Fig. 3 the shoes are connected at their forward ends to the frame by means of drag-bars and the polepivoted' at a point in advance of its rear end,asin Fig. 1. In this device, however, we have dispensed altogether with the bell-crank lever and pivoted the free rear end. of thepole to the straight lever M,'the latter being pivoted'to the hopper or to a bracket projecting upwardly fromth'e frame. The

lever M is provided with a hook M for engaging the teeth of the straight rack-bar M located in the rear of the hopper for holding the lever M in position. I Instead of using the rack-bar, as shown, it is'eviden-t-that a toothed sector can be employed therefor and answer all purposes.

In Fig. t we have shown the pole pivoted at a point over thefront of the frame and the rear end thereof carrying a lever N, provided with a toothed sector N for engaging a rackbar N secured to the front of the hopper or other convenient part. By turning the lever the engagement of the sector with the rackbar moves the rear end of the tongue up or down, and consequently causes a corresponding depression of elevation of the front end of the frameand the shoes or runners. The lever is provided with suitable lockingdevices adapted to engage a toothed. sector carried by the frame or hopper orboth.

Fig. 5. shows the tongue or pole pivoted at its rear end to the axle-of the ground-wheel or to bearings concentric with said axle, and a bell-crank lever O, pivoted at its elbow to the frame and connected to the tongue by link O In this instance the frame is provided with a toothed sector adapted to be engaged by the devices for locking the lever against movement.

- The construction disclosed in Fig. 6 is similar to that shown in 3, the main difference being that in Fig. 3 the lever M is pivoted at a point in advance of the axle, while in Fig. 6 it is journaled on the axle.

Fig. 7 discloses the tongue pivoted at its .l'ear end and carrying a lever I, having a toothed segment, which latter engages a slightly-curved toothed bar secured to the front end of the frame.

In Fig. 8 and also in Figs. 4., 5, o, and 7 we have shown the shoes connected directlyto the frame, the drag-bars of Figs. 1, 2, and 3 being dispensed with. v

By means of the devices disclosed We are enabled to change the angle of the shoe to the tongue and face of the ground by means of a lever without raising or lowering the shoes or aifecting the weight or pressure applied to said shoes to forceit into the soil.

In Fig. 10 we have shown the shoe and boot connected to a drag-bar made of spring metal, I

while in Fig. 11 we have shown the rear end of the tongue connected to the frame by a screw swiveled-at its lower end.

Some machines are made double-that is to say, with two frames and two poles for four horses. I In such machines the runners or shoes are raised in sections or gangs, and

out devices for tilting the gangs in the-same way. It is sometimes desirable to tilt one end of a wide machine to clear'a elod or bunch of trash or to level up a machine when a large we prefer-in such cases to employ independteam is attached 'to-one pole or tongue and a small team is attached to' the other pole or tongue. In this case the machine would have to be leveled up or. adjusted in some shape to ofiset the irregularity in the height of the tongues at the front end. Some prefer and do arrange the frame in. sections, and hence the desirability of tilting'in sections.

While we have described several forms of accomplishing the desired end, it is evident that other slight changes might be resorted to without departing from the spirit and scope of our invention. Hence we do not-wish to confine ourselves to the details shown, but

consider ourselves at liberty to make suchslight changes and alterations'as fall within the spirit and scope-of our invention.

Having fully described our invention,,what we claim as new, and desire to secure by Letters Patent,-is
