OF SAME PLAGE.
SPECIFICATION forming part of Letters Patent No. 328,952, dated October 2'7, 1885.
Application filed March 19, 1885. Serial No. 159,477. (No model.)
whereby the plow and the colter are caused` to rise and fall in unison.
|The invention is designed more particularly as an improvement on the construction rep-,
resented in the application for Letters Patent of the United States tiled by Thomas Duke on the 8th day of September, 1884, No. 142,506, the aim of the invention being to provide a colter-operating device which should be more acceptable to the operator than that represented in the original application, and to adapt the same to be applied to plows already completed, as well as to those hereafter manufactured. Y
Referring to the accompanying drawings, Figure l represents a side elevation of my attaehment as it appears when in operative position, the plow-beam being Vindicated by dotted lines. Fig. 2 is a perspective view of the device as seen from the opposite side. Fig. 3 is a cross-section on the line ac 00 of Fig. l. Fig. 4 is a cross-section on the line y y of Fig.
l. Fig. 5 is a side elevation, in outline, of a plow having my improvements attached.
Referring to the drawings, A represents a metal plate adapted to tit against the side of the plow beam or frame, with horizontal flanges c, to embrace the upper and lower edges of the beam and assist in retaining the device in place.
B represents a bar designed to lie against the opposite side of the beamand connected at its upper and lower edges with the plate A by means of fastening bolts or screws b.
At its lower edge the plate A is provided with an ear, c, recessed to receive a journal, d, formed on the side of the vertical socket C, which is constructed of tubular form, as
shown, or of other suitable form adapted for the attachment of the stem or spindle of the colter thereto. Vhen of tubular form, the socket is provided with a lateral bolt or equivalent fastening device, e, to secure the spindle of the colter thereto. At its upper edge the plate is provided with the second ear, f,which receives and sustains the pivot or journal of an elbow-lever, D, one end of which is pivoted to a link, g, which is in turn pivoted at the opposite end to an arm, 72., formed rigidly on the side ofthe socket O, this construction and arrangement serving to impart motion from the elbow-lever D to the socket O, which is tipped in a vertical plane, or, in other words, about its horizontal axis, so :as to throw the colter upward or downward,into or out of the soil, as occasion may demand. rlhe lever D has a boss or projectionsimilar to that on the side of the socket, seated in the supporting-plate A, these bosses serving to relieve the fastening-bolts of a portion of the strain. The lever and the socket are confined in place by means ot the tie-bolt E, the two eXtremities of which are bent at right angles to the body in lines parallel with each other, and passed through the supporting-plate A, secured on the back of nuts applied thereto. The lever D is forked at one end and provided with a series of holes to receive the pivot connecting the same to an operatingbar, F, which is in turn connected at its opposite end to the lever G, by which the raising and lowering of the plow is effected.
In the drawings I have represented a plow attached to the frame in the same manner as in my previous application; but it is to be understood that the manner of connecting and adjusting the plow is not a material part of this invention, as my device may be connected with and operated by plow-adj us'ting levers or devices of either of the various forms at present known in the art.
It is to be noted as an advantage of the present contrivance that it is adapted for appli cation to existing plows as well as others with out change in their construction. Y
It is manifest that the marginal form or outline of the plate A may be modiiied at will,
provided it is adapted for attachment to the plow frame or beam, and also adapted to support the plow parts thereon.
It is preferred to extend the bolt E from the lever to the socket, as shown, for the reason that it serves to tie the parts together-and prevent them from being thrown out of position, the backward strain on the lever being counteracted by the forward strain on the socket. Instead of this bolt, two independent bolts having heads thereon may be usedone for the lever and the other for the socket; or, in place of the bolts, other fastening devices,such as are familiar to the skilled mechanic,may be employed. In short, it is to be understood that the substance of the invention consists in the lever and the socket connected with each other and mounted on a supportingplate, and that modications or variations in the details may be made to any extent within the range of mechanical skill.
The series of holes in the elbow-lever admit of the operating-bar being attached thereto at different points, so as to vary the extent of movement of the colter.
The position of the colter with respect to that of the 'plow may also be modified to a limited extent, as circumstances may demand, by adjusting the supportingplate A forward or backward on the beam or frame.
Having thus described my invention,what I claim is l. The colter supporting and adjusting attachment for wheeled plows, consisting of a plate provided, substantially as described, with means of attachment to the plow beam or frame, a colter-supporting socket pivoted to said plate, and an operating-lever pivoted independently to said plate, said members being constructed and combined for joint operation substantially as described and shown.
2. The anged plate Aand fastening-bar B, with their connecting devices, in combination with the socket C and elbow-leverD, pivoted independently to said plate, and the connecting-link g.
3. In combination with the supporting-plate A and the socket and lever mounted thereon and connected with each other, as described, the fastening-bolt E, constructed and applied as described and shown.
4. In a wheeled plow, a wheeled frame, a verticallyadjustable colter, and a plowedjusting lever, in combination with the colter, the pivoted socket having an arm thereon,the elbow-lever, the connecting-link, and the bar connecting said lever with the plow-adjusting lever.
In testimony whereof I hereunto set my hand,
