ATTACHMENT FOR LISTEB-GULTIVATQES. r

Specification of Letters Patent.

Patented Jan. l5, rare.

V Application filed August 20,1917. Serial No. 187,183.

To all whom it may concern:

I Be it known that 1, WILLIAM F. Bnsomrn, a citizen of the Unitcdifcltates, residing at Wichita, in the county" of Sedgwick and State of Kansas, have invented certain new and useful improvements in Attachments for Lister-Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its principal object to provide a simply constructed and incripensive arrangement of parts whereby any of the well known types of lister Cultivators,

may be easily'converted for use as ridge busters, that is for the purpose of cultivating the ridges as well as the furrows. Another object of the invention is to so mount the cultivator disks asto permit them to be easily adjusted by a hand lever or the like, so that they may be made to draw a greater or less amount of earth from the ridges.

Yet another object is to so construct the adjusting means of the disks, as to permit said means to be easily secured to and operated by the transverserock shaft which is usually employed for raising and lowering the shovels.

With the foregoing general objects in view, the invention resides in the novel features of construction andu'nique combinations of parts to be hereinafter fully described and claimed, the descriptivematter being supplemented by the accompanying" drawings which form a part of this specification and in which Figure 1 is a top plan view showing one of the improved attachments applied to a portion of a lister cultivator;

Fig. 2 is a rear elevation of Fig. 1; and

Fig. 3 is a longitudinal section on substantially the plane indicated by the line 3-3 of Fig. 1.

In the drawings above brieflydcscribed, the numeral 1 designates a portion of the connecting bar which usually extends between the two halves or units of lister cultivators which are constructed for operating By means of the arm 2 or any other suitable device, the bracket 3 on the rear end of the tongue 4, is swiveled to the bar 1, a transverse tubular frame member 5 being hinged at 6 to the bracket 3 for vertical swinging, said frame member carrying the usual standards 7 upon whose lower ends the furrow wheels 8 are rotatably mounted. Passing through the tubular frame member 5, is a rock shaft 9 having squared ends, it beingupon said ends that the shovels are usually mounted. Wl'icn applying the presentinvention, however, these shovels are omitted, but the adjusting lever-l0 ofthe shaft 9 and the rack 11 thereof, are retained since other parts are operated from the shaft 9 and the latter must therefore be held in adjusted position. i

c The construction so farbriefiy described may be found in a number of well known types of lister cultivator-s which operate 'upon the bell crank principle, that is by swinging the wheels 8 upwardly and downwardly to respectively lower or raise the cultivator disks. In the present showing, this swinging of the wheels 8 is accomplished'by means of a lever 12 which is fulcrumed to the tongue at and connected by means of suitable links or the like 13with the axles of the wheels 8. It is to be understood that this adjustment constitutes no part of the present invention but that it, as well as the features above described, are shown only for the purpose of illustrating the application of the improved features.

The usual disk carrying means are detached fram the frame member 5 and an inclined hanger or arm 14 is secured thereto between the standards 7 the upper end of said arm having a right angular seat 15 which receives the similarly shaped frame member 5, pivot-ally connected bolts 16 being provided for passage around the remainder of the member 5 for the purpose of securing it rigidly in the seat. The lower end of the arm 14 is preferably widened and provided with a pair of toothed bosses 17 with which similarly toothed plates 18 on a pair of vertically disposed bearings 19 coact, bolts or the like 20 being provided for securing said plates to the bosses, so that the bearings 20 may be adjusted from the vertical, whenever occasion should demand.

Pivotally connected with the lower or rear end of the arm ll, by means of vertical studs 21 which are received in the bearings 20, are two horizontally swinging shafts 22, said shafts carrying the usual or any preferred type of cultivator disks 23 which are mounted rotatably thereon. At 24-, a pair of links 25 are pivoted to the shafts 22, the front ends of said links being similarly connected with crank arms 26, said arms having guides 27 and set screws 28 for seof said wheels'and having a pair of sub curing them on the squared ends-of'thestant1ally vertical bearings, a pair of transshaft 9, so that turningofrsaidvshaft, .by means of the lever 10, will swing the shafts 22 forwardly and rearwardlyto vary the angular relation of the disks 23, whereupon thelatter are caused to move a greater orless amount of earth. In most types of the invention, one of the crank arms 26, in ad .dition to the guides 27 and screws 28, will be equipped with a channel shaped arm 29 by means of which the lever 10 is attached thereto. In other cases, however, in which the lever is" permanently secured to the shaft '9 itis unnecessary to provide the arm 29. By constructing the attachment as or substantially as above described, it may be eas- 11y and inexpensively manufactured and marketed, yet will be attachable to practically all types of lister cultivators, thus making it possible to convert the comparatively light cultivators into substantial ridge busters. One machine. may thusbe used for the two purposes, so that expense is greatly decreased. On account of these advantages, the specific features of construction shown and described, constitute the preferred form of the attachment. I wish it understood, however, that within the scope of the invention as claimed, numerous minor changes may well be made.

"I claim:

'1. In a lister cultivator, the combination of a transverse rockable frame member and means for rocking it, a pair of spaced standards depending rigidly from said frame member and wheels on the lower ends of said standards, a single inclined arm secured rigidly at its upper end to said frame member between said standards, the lower end of said arm being disposed centrally in rear .verse disk-carrying shafts pivoted at their inner ends to said bearings for horizontal sw1nging,l1nks extending forwardly from said shafts, crank arms to which said links are connected, a transverse rock shaft adjacent said framemember and carrying sald crank' arms, and means for rocking said shaft. p j

2. An attachment for lister cultivators comprising an inclined arin widened-hori- 'zontally at its apper 'a. 1 0we1- ends. and having atsaid upperlend a. transversely extending L-sliaped seatyto receive a transverse frame member of the cultivatonmeans coacting with sa d seat for, r gidly securing said arm to saidframe.member, the lower end of said arm being disposed in a vertica l transverse plane and having horizontally spaced bosses whose rear s1des are toothed,

pairof platesfhaving' teeth engaging the teeth of said bosses, bolts.connecting said plates and bosses to permit turning of the former, substantially vertical bearings formed on the outer edge portions or said plates, 'a pair of transverse 'disk carrying shaftswhose inner ends arepivoted to said bearings for horizontal swinging, and links extending forwardly from said shafts and having crank arms at their front ends for mounting. on a transverse rock shaft" of the cultivator. 1

In testimonywhereof have hereunto set my hand in 'the pres'encefof two subscribing witnesses.
