HENRY SMITH, OF LISTOWEL, ONTARIO, CANADA.

COMBINED RIDING I-IARRO'W AND CULTIVATOR.

Specification of Letters Patent.

Patented Feb. 11, 1911.

Application filed May 28, 1910. Serial No. 563,973.

To all whom it may concern:

Be it known that I, I'IENRY SMITH, of the town of Listowel, in the county of Perth, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Combined Riding Harrows and Cultivators, of which the following is the specification.

My invention relates to improvements in combined riding harrows and cultivators patented to me in Canada under Number 102,210 on the 27th day of November, 1906.

The invention consists of the features of construction and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings in which- Figure 1, is a perspective View of my machine complete. Fig. 2, is a detail of the forked quadrant and lever carrying the follower wheel. Fig. 3, is a detail showing a shank of the cultivator teeth arranged with the shank in an inclined position. Fig. 4c, is a similar view showing a shank of the cultivator teeth in a vertical position. Figs. 5 and 6 are perspective details of the adjustable link for holding the shank to the drag bars. Fig. 7, is a detail of the teeth. Fig. 8, is a detail of the adjustable bracket for varying the position of the drag bar laterally. Figs. 9 and 10 are longitudinal sections of the link through the notches.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the main frame of the machine comprising the side angle bars A and the connecting cross front bars A reversely set to each other and the rear T-shaped cross bar A and the intermediate T-shaped cross bar A All of the cross bars are set in the reverse position or with the angle uppermost.

B B is the main axle, which is divided and is a crank axle and journaled at the outside in suitable bearings B secured to the side bars A C are the wheels, which are located on the end of the axle.

A. A are bars located parallelly to the side bars A and secured to the bars A and A respectively.

D is a loop-shaped bracket secured to the bars A A. and provided with a series of holes D to which the double-tree may be pivotally attached in order to change the draft of the machine.

E are brackets secured to the bars A and provided with front eyes E in which are connected the rear hooks F of the forked end of the tongue F.

G are toothed quadrants secured to the bars A A and forming a bearing for the inner end of the divided axle B B. Each end of the divided axle is provided with a lever H, which has the usual spring-pressed plunger to engage with the quadrant and such levers are designed to raise the frame in relation to the wheels at either one side or the other, but independently of each other, so as to enable the machine to be driven on side hills or the like with equal facility as on the level ground.

I are a series of bars set on edge and extending from the bar A to the bar A. The bars are properly drag bars as they carry the shanks of the teeth J. They are set at desired distances apart by means of separating brackets K having rear holes K in the back of the brackets and side holes K in the sides of the brackets. Through the side holes K and the ends of the bars I extend bolts and the rear holes K are set equidistant apart. By the interposition of one or more brackets K between the bars I both to the front and to the rear the position of the drag bars I laterally in relation to each other both as to distance and inequality or equality of space may be cletermined as may be most suitable to the class of soil in which it is desired to use my cultivator.

The tooth J comprises the shank J and the share casting J suitably bolted thereto, the main share J bolted to the casting J and the point J bolted to the nose of the casting J The share J 3 and point I may be readily detached when desired, so that if the point wears out it may be readily re placed.

I preferably provide a short bar I at each side of the machine and to the outside of the frame, such short bar being secured to brackets 3 secured to the side bars A. I also attach the teeth or shares to these bars. In order to attach the teeth or cultivating shares to the bracket bars I provide a substantially rectangular link L through which the shank as well as the bracket bar extends, it being placed thereon.

The shank J may be set in the vertical position and consequently the teeth correspondingly set by setting the link L in the position shown in Fig. 1-, and substantially as shown in Fig. 5, the link being provided with notches L and L as shown in dotted lines, which abut or straddle the shank and notches If and L, which abut the bar (see dotted lines in Fig. l). In order to set the shank in the inclined position and'the teeth correspondingly the links L are brought, so

that the rounded ends of the link ride on the shank and on the drag bar as indicated in Fig. 3.

The shank J is held in any desired position on the drag bar and at any desired height by set screws 5, which extend through the sides of the link L and abut the shank J or bar I depending, of course, on the side of the link through which the set screw extends.

M are runners, which are suitably secured by bolts M to an angle bracket A normally secured at the front of the angle bar A by bolts M The bolts M and runner may be moved inwardly and the bolts extend through holes l depending on the depth and width of the furrow. The runner may be also adjusted vertically, the bolts h/ 1 passing through supplemental holes 5 in the front of the runner. The fronts of the runners are round and they extend back in one piece, the rear ends being free and, therefore, essentially different from my former patent.

N is a follower wheel, which is journa-led in a fork N the spindle N of which extends through a bracket N secured to the rear bar A A. quadrant N is formed on the bracket N A lever N 5 is also pivoted on the inner endof the quadrant and pro vided with a suitable spring-pressed plunger, and the bottom end of the lever is connected by a bar N to a pin N in the boss N formed on the sleeve held between the collars N on the top of the spindle N It will now be seen that by manipulating the lever N thefollower wheel N may be raised or lowered and thereby regulate the depth the cultivators or teeth extend in the ground. The

fulcrum for the frame is, of course, on the runners M, the rear portion of which, of course, will yield according as the frame is raised or lowered on the follower wheel.

It will be seen-from this description that I have made several improvements on former inventions, which make my machine of great utility and capable of practically any adjustment that may be necessary in cultivators.

WVhat I claim as my invention is:

1. The combination with the main frame and runners at the front thereof and the wheels journaled on the ends of the crank axles held in the frame, of a follower wheel located behind the machine and adjustable vertically in relation thereto as and for the purpose specified.

2. The combination with the main frame and runners at the front thereof and the wheels j ournaled on the ends of the crank axles held in the frame, of a follower wheel, a fork in the lower endof which the follower wheel is journaled, a bracket secured to the rear end of the frame and through ,which the stem of the fork extends and provided with a quadrant, a lever provided with a spring actuated plunger coacting with the quadrant and pivoted on-the bracket and a link connecting the lever to a sleeve held on the'stem as and for the purpose specified.

HENRY SMITH.
