Be it known that I', DON CARLOS MATTESO'N, of Stockton; in 'the county of San Joaquin, and State of Carli# foi-nia, have invented a new and improved Gang-Plough; and I do hereby declare that the following is a full, clear, and exact description'thereof, which will enable others skilled in the art to make and use thesame, referL ence being had to the accompanying drawings, forming part of this specification.l

This inventicn'relatcs to a new and useful improvement in gang-ploughs, and it consists in alpeculiar con Astruction of the same, wherebylthedithculty hitherto attending the springing and warping of the frame is avoided. The invention -also consists in a novelland improved arrangement of the dra'ght-attachment, whereby the same may be placed ata suciently low point without curving the framedof" the machine downward at its front part,

as is'now required. The invention consists, finally, in a. novel arrangement of the caster-gauge wheel, whereby the sameis prevented from becoming choked or clogged with weeds and trash.

In the accompanying sheet of drawings- Figure 1 is aside `view ofrmy invention.

Figure 2, 'an-.inverted plan of the same.

Figure 3, an inverted plan of a portion of the same.

Similar letters of reference indicate corresponding parts.

The frame of the device is composed of two parallel beams, B, the former, A, being considerably `.longer than the other one, B. These two beams are connected by two oblique or diagonal bars, C @which are parallel 'with each other, and bolted rmly, at their ends, to theheamsA B, (see iig. 2.)

To these beams C C the ploughs D are attached, which ymay be constructed in any of the`known ways. The two beams C C answer equally as good a purpose as a single plank or wide bar, hitherto employed, and not liable to spring and warp, as is the case with the plank or wide bar, and which occasions considerable diiculty. This simple feature adds greatly to the value of my invention.

To the front end 4of each beam A B, there are secured, by bolts, two metal bars, E which are sobeut o! curved as to extend downward, and are secured together,ithose of each beam, at their front ends, by a bolt, a. The b'ars F serve as braces to the bars E, as will be seen vby referring to iig. 1.

Gr is a bar, the ends of which are secured, by the bolts a, to the front ends of the'bars E F. VThis bar lGr is perforated with holes, b, through any ofwhich bolts c pass, to secure acplate, H, -to the bar, said plate H having an eye, el, formed at its front end, through which a ring, I, passes, to which the double-tree is attached. By adjusting the plateH more or less to the right or left, more or'less land maybe given the ploughs, as desired, and, by having the pl'ateH attached to the bar G, which', on account of beingjzttached'to the bars E F, is below the beams A B, a low draught-attachment is obtained without curving thepbeams A B, which is a great saving of expense in constructing the frame of lthe device. v

J represents a caster-gauge wheel, which is attached to a vertical arbor, K, the latter passing loosely up through the beam A, and attached, at its upper" en d, to a lever, L. The lower part of the arbor K is curved, so as to bc at oneside of the caster-wheel, the axle e extending from K at lright angles. The arbor Khas a scraper,j',.extending at right angles from it., and across the face of the wheel, in'order to keep the periphery of the same free from earth. In consequence of having the wheel J attached to the arbor K without a fork, weeds, trash,&c., are not liable to catch and choke up the wheel, there being no'place kfor them to lodge, a dilculty which occurs, in a greater orless degree, with all cnster-wheels which are set in a forked arbor.`

I claim as new, and desire to secure by Letters Patent- 1. The bars E'F, attached to the front ends ofthe beams A B, with the perforated draught-bar G attached thereto, substantially as and fo'r the purpose specified.

2. The attaching of the caster-wheel J to a single arbor, K, provided with a scraper, j', substantially as and for the 'purpose set forth. Y Y

` DON CARLOS MATTESON.
