DISK ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 781,735, dated February '7, 1905.

Application filed August 3,1904. Serial No. 219,363.

Be it known that l, Winnmn A. )loGmn- ERY, a citizen of the United States, residing at Maytlower, in the county of Clay and State of North arolina, have invented a new and useful Disk Attachment, of which the following is a specification.

This invention relates to disk attachments for plows, cultivator-s, and the lilte: and it has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability. and general ctliciency.

\Yith these and other ends in view, which will readily appear as the nature of the invention better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

in the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes and modifications may be made within the scope of the inven tion without departing from the spirit or sacrificing the etticiency ot' the same.

In said drawings, Figure 1 is a side elevation of a double cultivating-plow, showing the attachment applied thereto. Fig. 2 is a perspective view showing the attachment separated from the plow. Fig. 3 is a sectional view taken on the line 3 3 in Fig. 1. Fig. 4 is a perspective detail view showing a portion of the hub with one of its flanges, the adjacent end of a brace, and the intermediate adjustingwed ge.

attachment seen from the inner side. Fig. (5

Fig. :3 is a side elevation of the equipped with a spading-dislt and a special 3 brace used in connection with the latter.

I is a detail view illustrating a. modification.

Correspomling parts in the several ligures are indicated by similar numerals t reference.

The improved attaclnnent includesa hub 1, provided with radially-extending flanges 2 These flanges are for convenient connection Fig. i

with braces T and 5, each of which is connected with its respective flange by means of a pivotal bolt 6, extending through the brace and flange and also through an interposed wedge-shaped l)l0(:l{ T, which may be so adjusted as to cause the braces to be held at various angles with relation to the tlanges and consequently to the hub l. The brace is provided at the end thereof with a boxing 8, which hingedly engages a clip 9, by means of which it is connected with the beam of an ordinary plow, as illustrated in Fig. 1 of the drawings. The brace & is provided with a slot 11, engaging the head of a hook-bolt 12', whereby it is likewise connected with the plow-beam 10. It will be seen that the slotted brace t is capable of adjustment with relation to the plow-beam, said adjustment being etl'ected by means of a lever 12, t'ulcrumed at T3 and having a springactuated dog H engaging a cam-segment 15, whereby said lever and its related parts may be retained at any desired point of adjustment. The tree end of the lever 12 is connected pivotally with one of a plurality of perforations 16 by a linlt 0r hanger 17, the lower end of which is pivotally connected with the llange ot the hub.

The hub or bushing 1 serves to support a disk 18, which may be of any desired construction. In Fig. 1 an ordinary solid concave-convex dislt has been shown. In Fig. (i has been illustrated a spading-dislt, (specially designated 19,)and it is to be understood that a dislt of any suitable well-known construction may be used in connection with this device. lVhen a spading-dislt is shown, as in Fig. 6 of the drawings, l prefer to substitute for the brace 5 a special brace 20, having a shouldered end .21, as shown.

ln Fig. T of the drawings has been illustrated a modilied form of the invention whereby provision is made for the lateral adjustment ot' the dislt instead of the vertical adjustment, which is etl'ected through the medium ot' the brace LT and adjusting-lever 12 in the construction alreadydescribed. Under this modification the brace connected with the rearwardly-extelnling l'lange 2 of the hub, which brace in this ligure is designated t", is l bent to form an arc, the upper end of which,

which is provided with a slot 11", is adapted to rest upon theleft-hand beam of a double plow, with which it is connected adj ustably by means of a hook-bolt 12*. It is obvious that this construction enables lateral adjustment of the hub carrying the disk to be efiected in a simple and convenient manner.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. \Yhen a solid disk is used, it may be adjusted at any desired angle with relation to the growing plants, so as to throw the loose dirt over the roots of the plants in advance of the plows, thus protecting the plants and enabling the weeding operation to be performed without injury to the plants. Whenever desired. a spading-disk or a disk of any other suitable special construction may be substituted for the solid disk, and the device is thus capable of a varietyof uses, which will be readily understood 5 and appreciated.

Having thus described the invention, what is claimed is 1. In a disk attachment, a hub having rad iallyextending flanges, braces connected with said flanges, pivotal bolts constituting the connecting means, and wedges mounted upon said pivotal bolts between the braces and the flanges.

2. In a device of the class described, a hub having rad ially-extending flanges, braces connected with said flanges, a plow-beam, means for connecting the forward brace to said plowbeam, a hook-bolt engaging the latter and extending through a slot in the rearward brace, a link connected pivotally with one of the flanges of the hub, and an adjusting-lever pivotally connected with said link.

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