I I Application filed July 18, 1896. Serial No. 599,63l. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM G. MUNN, a citizen of the United States, residing at Louisville, countyof Jefferson, and State of Kentucky, have invented certain new and useful Improvements in a Combined SeedingMachine and Disk Harrow, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to improvements in grain-drills in which furrow-opening disks are employed to open a furrow for the grain, and it has particular relation to those certain novel and useful constructions and arrangements of parts, to be hereinafter particularly pointed out and claimed, whereby the machine may be readily and easily adapted to serve either as a grain-drill, a broadcast seedingmachine, or a disk harrow and cultivator.

In the drawings, Figure 1 is aside elevation of a device embodying myinvention. Fig. 2 is a top plan view of same. Fig. 3 is a horizontal section taken through one of the disks. Fig. 4 is an end view of the block between the drag-bars, lookingin direction of arrowin Fig. 3. Fig. 5 is a vertical section taken through one of the disks on lines a b of Fig. 1. Fig. 6 is a top plan view of my device, showing a modified construction f r attachment of the grain-receiver. Fig. 7 is a side elevation of this modified construction.

In the drawings I have shown but one of my improved devices, but it will be understood that for the complete drill such number of similar parts are employed as go to make up a complete machine.

A A represent one pair of the drag-bars of the seeding-machine coupled to the frame in the usual way, as many sets of drag-bars being employed as there are seed-discharge tubes or disks for the machine. bearings between these drag-bars and inclined at a proper angle to the line of draft is a disk B. This disk is provided with an elongatearll hub o, mounted to revolve on the spindle e is a cap within which the end of the spindle fits to sustain same, and both spindle and cap are provided with square shoulders ff,

J ournaled on suitable within the recesses of which the drag-bars fit to prevent the cap and spindle from turning. Both spindle and cap are also provided with protecting-flanges g g, fitting around the hub c of the disk to keep out dust and dirt, while the spindle is slightly longer than the diskhub 0', so that when the bolt C, which passes through the drag-bars and upon which the parts are mounted, is tightened the disk can turn freely in its bearings.

his an oil-box cast on the spindle and provided with a cover to keep out dust and dirt, through which box lubricant is supplied to the bearings between the hub and spindle.

D is the seed conveyer or receiver,connected with the seed-hopper by suitable tubingin the usual way and located on the convex side of the disk B and to the rear of its journal-bearin gs. The lower end of the receiver D is provided with a downwardly and forwardly extending portion E, which extends over and in front of the seed-delivery openingo' and is made to conform to the disk, as shown in Fig. 5, thus serving as a scraper for the convex surface of the disk and as a guard or shield to protect the descending seed from being scattered by stubble, grass, or other obstacles and as a guide to aid in the delivery of the seed to the furrow formed by the disk.

F is a block which fits between the rear ends of the drag-bars and is secured therein by the bolt G, which passes through the dragbars and longitudinally through the block, the block being provided with shoulders k to form channels for the snug fitting of the drag-bars and to prevent the block from turning or twisting. The upper surface of this block is also formed with a channel Z, within which fits the bracket-arm m on the seed-receiver D, by which the receiver is bolted to the block by bolt 72.

At the rear of the block F are the lugs 19 p, within which is hinged the flat rod H, connected above to the usual arm J, rocker-bar K, and lifting device, while the usual coiled spring L bears between the arm J and the sliding collar M, which is held from descending by the pin r, and thus variable pressure is brought to bear on the drag-bars to force the furrow-cutting disks into the ground any desired depth. The lugs p p converge at the base to form the vertical lip 8, having a hole within which may be attached, when desired, the usual drag-chain covering device.

t tare lugs extending rearwardl y from block F, with bolt-holes in line with the drag-chain hole in the lip .9, so that when the drag-chain covering is removed the supplemental dragbars N N maybe bolted thereto by bolt 0. These supplemental drag bars N N carry journaled therein at the rear the coveringwheel P.

R is the presswheel-lifting bar, coupled to the drag-bars N by pin a and passing up through a slot in the rear projection 2' in the sliding collar M and held therein by the pin '10, so that when the rocker-arm J is raised the press-wheel will be raised also.

J is a coiled spring bearing between the rear projection 21 on the collar M and the pin it, so that when downward pressure is exerted on the bar II by the shifting of the rockerbar the disk and covering-wheel are forced downward under the pressure of the two springs L and J, and when the bar II is raised both disk and covering-wheel are raised clear of the ground.

U is a scraper secured on the bolt G to the drag-bars and bent in such a manner as to scrape the concave surface of the furrowopening disk,or these scrapers may be secured in any other desired way to serve their purpose.

It will be understood that while I have illustrated my grain-receiver D as connected to the block F the receivercan, if desired,be connected directly to the drag-bars. The grainreceiver D, however, is entirely distinct and separate from the disk B or its bearings. This construction I have illustrated in Figs. 6 and 7. Instead of attaching the grain-receiver to the block F, I provide a cylindrical block or tube d,which is bolted between the drag-bars by the bolt G. The grain-receiver is attached directly to the drag-bar by the bolt g, and the rear extension of the grain-receiver is provided with two lugs ff, which embrace the tube (1' and hold the receiver D rigidly in place when it is bolted to the drag-bars.

e is a collar provided with a pair of upwardly-extending lugs 7L h", to which the bar II is attached and also the downwardly-extending lug g", to which the usual drag covering-chain can be attached. This collar is also provided with a forwardly-extending arm a, while the bolt 9 for connecting the grain-receiver to the drag-bars also passes through this arm, thus locking the collar from turning when the spring-pressure is applied.

The supplemental drag-bars N N for the cov-' ering-wheel I are attached to the implement on the tube (1. In other respects the corn struction is similar to that already described in connection with what is shown in Figs. 1 to 5.

\Vith my construction and arrangement as above described the implement can be readily and easily adapted for many different purposes. The furrow-opening disks being entirely separate and distinct from the grainreceivers, whenever desired the receivers can be removed and the machine used as a broadcast seeder, the disks harrowing the seed into the ground as it is distributed in front of them, or the receiver can be removed by merely slipping the connecting-bolts, and the seedhopper being also removed the machine can be used as a spring-pressure disk harrow or cultivator. This simple and easy adjustment of the parts and the means by which I effect it, whereby the character of the implement may be changed at a moments notice, forms one of the chief features of my invention.

Having thus described my invention,what I claim, and desire to secure by Letters Iatcut, is
