Specification of Letters Patent.

Patented May 8, 1906.

Application filed February 18, 1903- Serial N- 143,942.

To all whom it may concern.

Be it known that I, SAMUEL L. ALLEN, a citizen of the United States, and a resident of Moorestown, State of New Jersey, have invented certain new and useful Improvements in Cultivators, 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 certain improveto that class known as pivot-wheel walkingcultivators. S

The objects of my invention are, first, to provide a simple inexpensive machine of the type stated and to generally improve its construction and efficiency; second, to provide a pivot-wheel cultivator having handle-bars for the use of the operator in steadying the machine, which also serve as levers, one for raising and lowering the gang-frame to regulate the depth of penetration of the teeth into the soil and the other serving to turn the pivot-wheels for the purpose of steering the machine, and, third, in providing an improved form of supporting-frame and gang together with improved means for attaching the shafts of the machine.

With these objects in view my invention consists in the construction, arrangement, and combination of parts, such as will be fully set forth hereinafter and particularly noted in the claims made hereto.

Referring to the accompanying drawings, Figure 1 is a plan view of a cultivator constructed in accordance with my invention. Fig. 2 is a side elevation of the same, the teeth of the gang being shown as entering the ground; and Fig. 3 is a detail section illustrating the end of the gang-frame.

In carrying out my invention 1 rovide a main frame 1, which is substantial y rectangular in form, consisting of the side bars 2 and 3 and the transversely;clisposed front bar 4 and a transversely-disposed bar 5, located a short distance in rear 01 the front bar and connected at its ends to the side bars 2 and 3. To the rear ends of the two side bars 2 and 3 are ri idly connected the twin bars 6 and 7, which orm the gang-frame. The upper bar 6 of the gang-frame comprises a flat steel. bar having its ends turned down, as illustrated at 8, while the lower bar 7 is channel-iron or steel and has its ends turned up, as illustrated at 9' in Fig. 3 of the drawin s, so that when the two bars are assembled the ments in cultivators, and more particularly j .bar of the main frame.

depending section 8 will fit into the channel of the section 9. These two parts are bolted to the side bars by the bolt 10, as illustrated. The lower channel-bar 7 is adapted to carry thel clamps 11, which support the tool-standarr s.

The pivot-bars which carry the supporting-wheels 12 comprise the vertically-disosed bar 13, having its lower end curved and bent at substantially right angles to the section 13, as illustrated at 14, the section 14 serving as the axle for the supporting-wheel. A box 15 is secured around the lower section of the pivot-bar, and resting on the top of this boxing is an arm which forms a part of the vertically-disposed b r 16, which is bolted to an angle-bar 17, secured to the cross- The upper end of the bar 16 is bent at substantially right angles and forms a bearing for the u per end of the pivot-bar 13. A brace-rod 18 is provided for further supporting the pivot-supporting bar 16, which is secured at its lower end'by means of a bolt 19 to the lower portion of the bar 16 and at its upper end to the front framebar 4 by means of the bolt 20.

Secured to each of the pivot-bars 13 are the rearwardly-extending arms 21, Which have secured to their free ends a connecting-bar 22. This connecting-bar 22 is provided with a series of apertures 23, adjacent each of its ends, so as to allow the pivot-bars to be adjusted laterally when it is desired to Widen or narrow the tread of the Wheels. Pivoted about in the center of the connecting-bar 22 is a link 24, which is pivoted at its other end to a lever 25, which is in turn pivoted to a bearingblock 26, secured on the bar 6 of the gangframe. This lever 25 is bolted to the handlebar 27, and by moving the said handle-bar laterally the pivot-bars and their wheels may be turned in either direction for the purpose of steering and guiding the machine. For'the purpose of keeping the handle-bar 27 steady a pin 28 is provided which passes'through an aperture formed pivot and through a projecting lug 29, carried by the bearing-block 26. When it is desired to move the lever 27 laterally to turn the pivot-wheels, this pin 29 must of course be removed. i

The shafts are provided at their rear ends with the irons 31, having eyes provided in their free ends which fit between the clips 32, formed in the front corners of the main frame, and the pivot-bolts 33, carried the in the lever 25 in rear of its" clips, pass through the eyes of the irons 31,

erebysecuring the shafts to the main frame. In the center of the front frame-rod 4 are the angle-irons 34, rigidly secured to the rear side of the said frame, and between these angleirons is secured a segmental rack 35, which-issupported on the bolt 36, carried by the angle-irons. This segment 35 has rigidly secured to its lower portion an arm 37, which extends forwardly and is then curved upwardly and secured to the under side of the cross-bar 38 of the shafts by means of the bolt 39, so that the said segment 35 is rigid with the shafts. Pivoted on the bolt 36 are the levers 40 and 41, which are bent at a slight angle and have their rear ends rigidly secured to the handle-bar 42. The lever 40 is provided with a springpawl 43 of the usual construction, ch is operated by a rod 44, which extends to the rear end of the handle-bar and is provided with a pivoted operating-handle 45 of the usual construction. Pivoted to the bolt 36, adjacent the levers 40'and 41, is a brace-bar 46, which is inclined downwardly and rearwardly, and has its other end rigidly secured .between the two bars 6 and 7 of the gangframe and which serves the purpose of strengthening the main frame and making the same very rigid.

Secured to the upper bar of the gang-frame 6 is a bar 47, which extends upwardly and through a slot provided in the handle-bar 42 and is secured to the said handle-bar by means of a bolt 48, which passes through the handle-bar and through an elongated slot 49, provided in the upper portion of the bar 47. A collar or clip is rigidly secured on the bar 47 some distance above its connection with the gang-frame, and inter osed between this clip and the under side 0 the handle-bar 43 is a coiled spring 51, which exerts its tension on the gang-frame and at the same time allows or admits of the said gang-frame yielding in an upward direction in the event of the teeth coming in contact with stones or other obstructions in the ground.

In the operation of my machine it will be readily understood that by operating the lever 42 the gang-frame and its toolsmay be raised or lowered and held in adjusted position by means of a rack-and-pawl mechanism, and the frame may be also lifted, so that the teeth will clear the ground during transportation to and from the field. This lever 42, together with the lever 27 ,perform a double functionthat is to say, they serve as handle-bars for the use of the operator in steadying the machine, while the handlebar 42 serves as a lever for raising and lowering the gang, as above described, and the handlebar 27 serves as a lever for turning the pivot bars which carry the supporting-wheels when it is desired to guide the machine in either direction, this being accomplished by means of the connecting-bars which connect the saidlever with the pivot-bars. The lever 42 may also be used to regulate the height of the shafts to suit the horse, as the segment 35 is pivotally mounted on the bolt 36 and rigidly connected to the cross-bar of the shafts by means of the bar 37, so that after hitching up the horse the height of the front part of the shafts can be regulated by the operation of the lever 42. It will also be noted that the entire frame is supported on the pivot-bars and swings on the axle formed by the lower or horizontal portion of said pivot-bars. The construction of the frame is very simple and inexpensive to manufacture, while at the same time it possesses great strength and durability, and the entire machine is very eflicient in its operation.

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