CHARLES LA DOW, OF ALBANY, NEW YORK.

SULKY SPRI NG-TOOTH HARRO W AND CULTIVATOR.

SPECIFICATION formingpart of Letters Patent No. 269,068, dated December 12, 1885?.

V Application filed February 11, 1882. (No model.)

To all whom it may concern Be it known that I, CHARLES LA Dow, a.

citizen of the United States, .and residing in the city and county of Albany, and State of New York, have invented a new and useful I111- provement in Sulky Spring-ToothHarrows teeth to work the soil, and are mounted on wheels and capable of being adjusted and set to work the soil to any required depth.

This invention consists in the combinationof a draft-frame, arockingbar connected therewith, ground-wheels supporting the bar and serving as bearings for the rocking movement of the same, a series of spring-teeth of differout lengths, adjustable in a direction around the rocking bar relatively to each other to vary the penetration of their points, and having their points arranged in different vertical planes across the line of draft, and means for rocking the bar and teeth.

The invention further consists in the combination of a draft-frame, a rocking bar connected therewith, ground-wheels supporting the bar and serving as center bearings forthe rocking movements of the same, spring-teeth attached in series to the rocking bar with their points arranged in different vertical planes, and means whereby the teeth may be varied and held in one series relatively to the teeth in another series by frictional contact between the teeth and their carrying rocking bar.

The invention further consists in the combination of a draft-frame supported by wheels, a rocking bar attached to the frame and arranged between the wheels, a series of teeth on the bar, and a section orextension also carrying teeth, and capable of being attached to the rocking bar for varying the width of the soil-working parts of the machine.

The invention further consists in the combination of a draft-frame, a rocking bar attached thereto, mechanism for rocking the bar and holdingit as adjusted, teeth adjustably attached to the bar, and mechanism whereby part of the teeth can be reversed without interfering with the rocking of the bar and the work and movement of the other teeth.

The'invention further consists in the comened to the cross-bar.

' E by means of suitable springand pawl.

brating spring-teeth mounted on said bar, the

teeth adjacent to the wheel-hubs being extended or bent laterally to admit the hubs be tween them, and thereby maintain the proper relative position of the cutting'points of all the teeth.

Referring to the drawings, Figure 1 represents a top view of my invention. Fig.2 represents a side view of the same. resents the adjustable section or extension for varying the width of the operation of the machine.

A A are the ground-wheels, and are mounted on the axle O. B is the cross-bar; .D, the pole; O O, the braces securing the pole and cross-bar together. E isthe toothed rack fast- The axle (3 is preferably made of gas-pipe or other hollow tubing, and is arranged to'rock through the center of the wheel-hubs, which act as journal-bearings therefor. The cross-bar is connected with the axle by eye-bearings H I H I. The teeth a. a a are preferably made of flat spring-steel, and are bent at their upper ends to form a loop or clasp, partially encircling the axle C. The teeth are made of dift'erentlengths and curvatures, so as to bring their points in different vertical planes across the line of draft, in order to thoroughly work the ground at one transit of the machine, and yet allow stones and rubbish to readily pass through between the teeth.

b b are clips arranged above and below the clasp of the tooth. V

c c are clampingbolts for locking the tooth to the axle by frictional contact.

F is a ratchet-lever engaging with the rack y rocking the lever the teeth can be either forced into the ground or raised above it, the rack and pawl holding the teeth and their axle-bar in any position adjusted or desired.

In order .to force all the teeth into the earth uniformly at different depths of penetration, the clamping-bolts c 0 may be loosened 0n the rear series of teeth, and they can be set at the same depth as the front teeth, the bolts retightened, and the teeth securely held in any desired position relatively to their axle-bar.

Fig. 3 rep- The upper end of the tooth-clasp has an upward or return bend to prevent the bindingclips from slipping ofl'.

When it is desired to use the machine as a cultivator of rowed crops the bolts and clips on the teeth near the center of the machine may be loosened sufficiently to allow the axlebar to be rocked freely within the clasps of said teeth. These center teeth may then be thrown forward until their weight will cause them to overbalance, and they can be thus carried in reversed position on the crossbar without being disturbed by the rockingof the axle when operating the teeth at work,'and without being seriously in the way of the driver on his seat.

3 l l l retaining said pin Q, and the axle-extension U- relatively to the axle C, the linchpin performing the office of keeping both the wheel and the axle-extension in place.

. of the wheel.

Spring-teeth are placed upon the axle-extension in the same manner as upon the axle between the wheels. When cultivating rowed crops or on any other proper occasion the'axleextensions may be dispensed with and the machine used without them. The teeth adjacent to the wheels are bent sidewise in order to bring their cuttin g-points in proper place relative to their line of draft and to thecutot' their adjoining teeth, and at the same time allow a hub of suitable length to be used on the axle between the teethin proportion to the height The seat S and standard V are mounted in the socket on v draft-pole I) in the usual manner. The draft-pole D and crossbar B are kept from undue lateral movement by placing the eye-bearings H l H between the tooth-clasps on the axle (3. Any of the teeth between the wheels may be loosened on the axle and thrown forward and reversed on the cross-bar without attecting the work and rocking movements of such teeth as may be left working the soil.

The machine may be made either with or without extensions for the axle and of any width desired, and the extensions may be used on one side only or on both. The teeth may be constructed so that their points will stand in one vertical plane or several across the line ofdraft. Wheels of any diameter may be used, according to the nature of the work required. Having described my invention ,what lclaim, and desire to secure by Letters Patent, is

1. The combination ofa draft-frame, arocking bar connected therewith, ground-wheels supporting the bar and serving as bearings for the rocking movement of the same, a series of spring-teeth of different lengths, adjustable in a direction around the rocking bar relatively to each other to vary the penetration of their points, and having their points arranged in different vertical planes across the line of draft,

and means for rocking the bar and teeth, sub-- ported by wheels, a rocking bar attached to' the frame and arranged between the wheels, a series of teeth on the bar, and a. section or extension also carrying teeth and capable of being attached to the rocking bar for varying the width of the soil-working parts of the machine, substantially as described.

4. The combination of a draft-frame,a rocking bar attached thereto, mechanism for rocking the bar and holding it as adjusted, teeth adj ustably attached to the bar, and mechanism whereby part of the teeth can be reversed'wita out interfering with the rocking of thebar and the work and movement of the other teeth, substantially as described.

5. The combination of a draft-frame supporting a rocking bar, ground-wheels arranged on the bar, and in the hubs of which'wheels the bar rocks, and vibratory spring-teeth mounted on said bar, the teeth adjacent to the wheel-hubs being extended or bent laterally to admit the hubs between them and thereby maintain the proper relative position of the cutting-points of all the teeth, substantially as described.
