f Y l l* IMPnOVEMENT 1N cuTTER-STOCK FOR, SWIVEL-P Lcws.,

` The Schedule referred/to in these Letters Patent' and makngpat of the same.

' That I, ELBRIDGE @.jllIATTHEWs', of Oakham, in'

the county of Worcester'and Gommonwealthot' Masf` sachnsetts, haveinvented certain new and useful Improvementsin Gutter-stock for Swivel-flows; and I` do `.hereby declare that the following is a full, clear, and exact description'of .the same," reference being had to 'the accompanying drawings forming a part'oi this 'Figure llrepresents a side 'iew of my-hnl'n'oved swi \el cntter,stock, and the `plo`w-beam to which it is attached, and' Figure '2 represents a'transverse vertical section online A B, fig. 1. A

- 'Tocn'able those skilled in `the art to which my invention belongs tornake'and-use the same, I `will pro- .ceed to describe it morein'detail'.

The'nature of my invention consists-l First?, in a hinged or swinging cutter-stock, as here- Second, in the combination with a hinged or swing'- A. ingcutten'stck, ofadevice Vfor-adjusting the cutterstock from right 'to left, and cica cerca, as hereafter explained.

In -the drawingsil 'represent-s the plow-beamte bolts a a, which pass through the ends of said plate, as fully indicated in fig. 1` ofthe drawings.

In. the 'lower sidel of the holding-plate, is formed a d0vetail'groo\e, for the reception 'of an adjusting and` Thelower side of the wedge :l is madev with a double bevel, which inclines towards its central part, thereby forming two inclined planes or wedges 1 '1, one at leach enthto'fit bevels .2 2, formed on 'theupper sideof the cutter-stock,'as fully indicated in the drawings fig. 2. -I'do not confine myself to `any particular' mode of adjusting the hinged cutter-stock B, as various devices may be employed'for that purpose.

It is very desirable to have a movable cutter on a swiuel-.plomso that .itfcan be adjusted to cut in line with the land-side, or standard, when turning or plowing either rglit or left-hand fui-rows, andwhch necessitates the movement of' the. cutter, from side to side, from one to three inches, -according to the differencel iu construction of the plows.

From the foregoing description it will he seen that this adjustment can be'-obtaned'-very readily by4 my invention, since the cutter-stock B and cutter D, can be Yswung from-right to left and cioe tersa, by the simple' movement ofthe wedge from side to' side, and it is at the same 4time held firmly in such adjusted position bythe action of said wedge. v

4Having., described my'fimproved cutter-,stock for swivel-plows, 1

What 1 claim therein as new and of my invention,

and desire to secure b'y Letters. Patent, is-i- 1. The cutter-stock B for supporting the'sward-cutter of a plow, when hinged tothe plow-beam, suhstantia-lly as and for the purposes stated.`

2.' 'lhe combination with a hinged, or swinging cutter-stock, ofthe wedge d'ofequimleut device for, atl-- justing thesanie from rightto left, 'or vice versa.
