SWIVEL-WHEEL ATTAOHIUENT FOR CULTIVATORS.

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed July 2s, 1.902. Serial No. 445,014.

To all whom it may concem:

Be it known that I, SAMUEL SnrrNnR, J rL, ofRoann, county of Wabash, and State of Indiana, have invented a certain new and useful Swivel-Wheel'Attachment for Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like-numerals refer to like parts. i

The object of this invention is to improve swivel wheel attachments to the beam of cultivators for limiting and regulating the depth of operation of the shoes or plows thereof.

The chief feature of this invention consists in attaching to the beam of the cultivator a frame in connection with which the swivel wheel frame is mounted that is provided with a vertical pivot rod at its rear end and a parallel brace and stop bar near said rod, mountinga tube on said rod that turns readilythereon, and securing adjustably on said tube a sleeve connected with the frame in which the wheel is mounted. Said sleeve on the swivel wheel frame can be slipped up or down onsaid tube and be secured thereto in adjusted position by set screws and it also carries on each side a stop lug adapted to engage the stop bar of the frame that is fastened to the beam of the cultivator. This makes a very simple and cheap construction that operates readily and is also readily adjusted.

In connection with the foregoing I provide a scraper for the wheel to keep its periphery clear of accumulated dirt, as the accumulation of dirt on said swivel wheel will often materially affect the pitch and depth of operation of the cultivator shoes or plows, as such accumulation of dirt has the effect of increasing the diameter of the swivel wheel. a

The full nature of this invention will be understood from the accompanying draw-- ings and the following description and claims.

In the drawings Figure 1 is a side elevation of the cultivator equipped with my attachment, the forward part of the frame of the cultivator being broken away. Fig. 2 is a plan view of the rear end of one of the beams. of the cultivator and of my attachment thereto, altered positions of the swivel wheel being shown by dotted lines. Fi 3 is a horizontal section on the line 33 0 1. Fig. at is an elevation of the near side of a portion of the device showing the means for connecting my attachment to the beam, parts being broken away. Fig. 5 is an elevation ofthe farther side of what apppars in Fig. 4. r

' here is shown a cultivator with the main -wheel 10 and beam 11 and frame 12, the lat-.

ter carrying a seat 13 and the'former carry ing a beam 14 on the lower end of which is secured a shovel or plow 15 that projects the usual distance into the soil 16.

20 there are a pair of stop lugs 24: adapted to engage the rear surface of the beam 14 to limit the upward and downward movements of the frame 20.

The rear end of theframe 20 is divided and the arms 26 thereof provided with a vertical brace and stop bar 25 between them and there are rearwardly extending portions of the arms 26 in which a rod 27 is secured that is vertical and parallel with the bar 25.

A tube 28 is mounted on said rod 27 loosely 'so as to readily turn thereon and it extends the full distance between the arms 26.

The swivel wheel 30 is mounted in the swivel -wheel frame 31 that has on its forward end a sleeve 32 which surrounds the tube 28 so as to be vertically adjustable thereon andis held in any adjusted position by the set screws 33. Therefore, in operation the sleeve 32 of the swivel wheel frame is rigidly secured to the tube 28 and said latter tube turns on the rod 27, but while the sleeve 32 has no rotary movement on and independently of the tube 28 it is vertically movable and adjustable thereon.

On the sleeve 32 there is a pair of sto lugs 35, one oneach side, that are adapte 'extends rearwardly and carries a scraper'37' on its rear end 1n position to engage and scrape the dirt off the periphery of the wheel 30. This maintains a uniformdiameter of the wheel 30, as it prevents the diameter of the wheel being increased by an accumulation of dirt on the periphery thereof. Hence the swivel wheel construction will maintainthe beam of the cultivator at a constant elevation in accordance with the adjustment thereof.

What I claim as my invention and desire to secure by Letters Patent is:

1. The combination with the beam of a cultivator or the like, of a rearwardly extending frame, a'vertically dis osed rod on the rear of said frame, a' 'tu -rotatably mounted on said rod, a swivel wheel frame provided at its forward end with a sleeve vertically adjustable on said tube, and means for securing said sleeve to said tube in its adjusted position, whereby the tube can turn on the rod and the sleeve can be vertically adjustable on said tube.

2. The combination with the beam of a cultivator or thelike, of a rearwardly extending frame secured thereto having a vertically disposed bar at its rear end, a rod secured to the rear end of said frame parallel with and near said bar, a tube rotatably mounted on said rod, a swivel wheel frame with a sleeve vertically ad ustable on sa1d tube, means for securing the sleeve to the tube, and a. lug extending from each side of said sleeve in position to engage sald vertical bar for limiting the lateral swinging movements of the swivel wheel frame.

a 3. The combination with the beam of a cultivator or the like, of a frame for carrying the swivel wheel that extends rear: wardly from said beam, a pair of bolts in said beam for securing said frame thereto, said frame being provided with a slot for one of said bolts that is curved concentrically with the center of the'other bolt (to permit the vertical adjustment of the rear end of said frame, and stop lugs on said frame adapted to engage said beam and limit the vertical oscillatory movement of said frame.

In witness whereof, I have hereunto affixed my signature in the presence of the witnesses herein named.
