COMBINATION-PLOW.

SPECIFICATION forming part of Letters Patent No. 439,214, dated October 28, 1890.

Application filed May 17, 1890.

To all whom it may concern.-

Beit known that I, JACOB Grrson WALTON, a citizen of the United States, residing at Davilla, in the county of Milan and State of Texas, have in vented anew and useful Dou ble- Shovel and Combination Plow, of which the following is a specification.

This invention has relation to a combination-plow, and among the objects in view is to provide a plow of cheap and simple construction and adapted to be converted into a single plow, a double plow, and what is commonly known as a straddle-jack, or into a three-plow cultivator, each and all of which are capable of both independent and combined adj ustments.

With the above general objects in view the invention consists in certain features of construction, hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of my invention, the same being Fig. 2 isa similar View, the same being shown as a two plow or double cultivator adapted to be adjusted into what is commonly known as a straddle-jack plow. Fig. 3 is a detail in side elevation of the beam. Fig. 4 is a detail of the removable central plow-standard. Fig. 5 is a similar view of one of the side standards. Fig. 6 is a detail in perspective of one of the angular seats.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 indicates the main beam of the plow, formed of either wood or steel and provided at its front end with an ordinary clevis 2. Secured to the upper edge of the beam is apost 3, having series of perforations 4:, through which is passed a bolt 5, said bolt also passing through the front ends of ordinary plowhandles 6, extending rearwardly and diverging, as is usual, and supported and braced near their rear ends by vertical standardsor braces 7, bolted to the handles and, as at S, to the rear end of the beam. The main beam is provided with three transverse bolt-openings 9, 10, and 11, respectively ranging from front to rear, and in two of the same there are mounted bolts 12.

13 designates angular seat-castings, formed Serial No. 352,145. (No model.)

of metal of substantiallytriangular form,and terminate at each end in laterally-projecting securing-plates 14, each of which is provided with a series of bolt-holes 15 to receive the bolts 12. The outer faces of the angular seats or brackets are provided with upper and lower parallel ribs 16, and intermediate said ribs there is formed a longitudinal seat 17, provided at intervals with bolt-holes 18 19 designates the side-plow standards, which are of goose-neck style, and are provided with the shovels 20. The forward portions of the standards are inwardly bent, as at 21, and are adapted to fit the converging seats of the 6 5 brackets or seat-castings, and are provided with a perforation 22, through which bolts 23 may be inserted for adjusting them laterally with relation to each other in the seats. By manipulatingthe bolts 12 and the seats it is apparent that the plows and seats may be raised and lowered, so as to take more or less into the ground.

As thus far constructed it will be seen the t I have provided a straddle-jack plow capablel of cultivating between rows of small crops, the distance between the plows being readily changed by the adjustment of the side-plow standards in the seats.

24 designates the central plow-standard, provided at its lower end with the shovel 25, and said standard is also of the goose-neck style. The front end of the standard is provided with a yoke or bifurcation 26, which embraces the upper edge of the beam 1, and in rear of said bifurcation there is bolted to the side of said standard a pair of straps 28, the lower ends of the straps embracing the standard 1. and being bolted thereto by abolt 29, which passes through the bolt-hole 11 and the beam 1.. The central standard, it will be observed, may be readily adjusted up or down by loosening the bolts passing through the straps, throwing the same at an angle and rebinding, so that the bifurcation or yoke will bind upon the beam. 7

With the addition of the central plow, I have formed a throw-plow cultivator, and by omitting the side plows I have a single plow, which may be either right or left handed, in accordance with the disposition of the shovel.

From the above construction it will be apparent that I have provided an extremely simple and cheaply-constructed agricultural implement capable of being converted into several and distinct apparatuses.

By adjusting the side standards one in advance of the other, I convert the straddle-jack plow into a double-shovel cultivator.

Having thus described my invention, what I claim is 1. In a plow, the combination, with a beam having perforations, of converging brackets terminating at their endsin adjustable plates bolted to the beam, and provided upon their outer sides with longitudinal seats, and between their edges with bolt-openings, and plow standards mounted in the seats, and bolts passing through the standards and the seats, substantially as specified.

2. The combination, with the main beam provided with bolt-openings, of opposite angularshaped seat-castings terminating at their ends in lateral heads having adj ustingholes, and provided on their inclined sides with longitudinally disposed seats having openings and goose-neck plowstandards mounted in the seats and having opening, and

, their inner ends inwardly disposed, and bolts passing through the standards and seats, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto afiixed' my signature in presence of two witnesses.

JACOB GIPSON WALTON.
