' IMPROVEMENT lIn 'PLoUeua TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Beit known that I, ELBRIDGE G. MATTHEWS, of South Natick, in the county ofMiddlesex, and Sta'te ot Massachusetts, have inventedA a new and useful Improvement in Ploughs, and do hereby declare the same tobe fully described iu the following specification, and represented in the aecompanyng drawings, of which- Figure 1 is a side elevation, I

Figure 2 a top'view,

Figure 3 a. rear end elevation, and

Figure 4 a longitudinall section of a plough-standard provided with my invention.

Figure 5 is a perspective view of a plough to which my invention appertains.

In such drawings, S denotes what is termed the plough-standard. From the rear part ofthe face a of the standard I extend upward and curve backward, in manner as exhibited iu the drawings, an arm, A.Apianged on its opposite sides, as shown at I) b t b. This arm is to sustain the two handles of the plough, which are to be laid against-opposite sides of the arm, and between and` against its ilanges, and are to be bolted to the arm. Furthermore, the arm is to give support to the beam, and is to have an odset or shelf, c, projecting'from it, for a support-or stay to the rear end of the same, and in rear of the said shelf there is to be a. h ole, d, .made down through the arm. Both the standard and the shelf are to be provided with projections or studs e e, to enter the plough-'beam when laid on the shelf` and top of the standard.' vThese studs -prevent laterai movement or" the beam on'its supports. The beam, when resting on them, is bolted to the top of thestandard. It is also secured down upon the shelf cby a bolt going through the beam and the hole d of the armi The `base part, a, of the standard provide with a shoe,'B, which I fasten thereto `by means of screw-bolts and nuts, the same being arranged as represented at 7i It in iig. 4. The shoe B embraces opposite s-ides of the standard, and is provided with a tooth,f, to enter the standard or abut against a buttress, g, arranged thereon, in manner as shown in iig. 4. The said tooth and buttress serve to' prevent the back strain on the shoe fromv breaking the bolts by whchithe shoe is confined tothe base of the standard. v

I am aware that a plough-standard has heretofore been made with a short arm below the beam, and to give support to one of the handles of theplough, therefore, I do not claim such. l My arm A extends upward, so as `to support both handles and the plough-beam. |ln=srefore-l 'l 1. I claim the arrangement of the arm A, its angesand shelf` e, or their equivalents, with the ploughstandards S, and its base a, as described.

2. I also claim the arrangement of the tooth f and the buttress g with the plough-standard and i'ts shoe, as set forth.

' 3. I also claim the plough-standard as made with an arm to extend back and up from its base, so as to give support to the two handles and the beam, substantially as set forthA ELBRIDGE G. MATTHEWS.
