III llll 1E ST GEORGE D. GRIFFICE, OF BIG SPRING, TEXAS.

CULTIVA'IOR.

To all whom it may concern:

Be it known that I, GEORGE D. GRIrFIcE, a citizen of the United States, residing at Big Spring, in the county of Howardand State of Texas, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had to the accompanying draw- 1ngs.

This invention relates to certain improvements in cultivators and it is an object of the invention to provide novel and im proved means whereby a cultivator of con ventional construction may be readily and conveniently converted into a surface cultivator. i

It is also an object of the invention t provide a novel and improved attachment for a cultivator whereby an ordinary cultivator may be employed as a surface culti vator and wherein the cutting'bladeis effectively held against displacement after the attachment has been applied to a beam. The invention also has for an object to provide novel and improved means whereby the beams of a cultivator may be effectively held against relative or lateral displacement.

The invention consists in the details of construction and inthe combination and an rangement of the several parts of myim proved cultivator whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the betcompanying drawings, wherein Figure 1 is a view partly in elevation and partly in section illustratlng an attachment constructed in accordance with an embodi-' ment of my invention and in applied position' V Fig. 2 is a view in side elevation'of the attachment as herein embodied, the coacting beam of a cultivator being shown in fragment;

Fig. 3 is a view in top plan of the device as disclosed in Fig. 1;

Specification of Letters Patent.

Patented Aug. 21, 1917.

Application filed October 16, 1916. Serial No. 125,909.

Fig. 4 is a sectional view taken substantially on the line 44 of Fig. 2;

Fig. 5 is a fragmentary view partly in elevation and partly in section illustrating a slightly modified form of invention;

Fig. 6 is a fragmentary view in elevation illustrating a still further modified e1nbodiment of my invention; and

Fig. 7 is a fragmentary view in end ele-.

vation of the device as disclosed in Fig. 6.

As disclosed in Figs. 1 to 3 of the accompanying drawings, B denote cultivator side beams of conventional construction and with each of which is operatively engaged a casting C for suitablysecuring to said beam B the shank S of a conventional cultivator plow and which plow is omitted in the accompanying drawings. I

Tdenotes a table preferably rectangular in top plan and which is provided with the depending split barrel 1 through which the beam B is disposed and coacting withthe barrel 1 and the table T are the clamping members 2 of conventional'type and which serve to effectively hold the table T to the beam B, as is thought to be clearly apparent to those skilled in the art to which my invention appertains, and as is particularly illustrated in Figs. Q'and 3, the table T is positioned in predetermined spaced relation relative to the casting C. It is not essential however that the table T and the barrel 1 be integrally connected as the table may be separate as'is disclosed in Fig. 5 of the accompanying drawings and wherein the table T is independent of the casting or barrel 1* but is eflectively held thereto through the medium of the clamping mem ber 2 Integrally connected with the barrel 1 is a second barrel 3 arranged at substantially right angles to the barrel 1 and table T. and through which is adapted to be directed the supplemental shank S.

An intermediate portion of the barrel 3 is enlarged, as at 4, and within said enlarged portion 4 is positioned the eye member 5 through which the shank S is directed, and said eye is provided with the radially disposed threaded shank 6 extending exteriorly of the barrel 3 or more particularly the enlarged portion 4 thereof and has coacting with its extended portion the clamping nut 7 whereby it will be perceived that the shank S may be effectively held in a predetermined longitudinal adjustment.

The upper end portion of the shank S, as indicated at 8, isangular in cross section and is adapted to be disclosed through an opening 9 of corresponding configuration produced in one end portion of the link or bar 10; The opposite end portion of said link or bar 10 is provided with an opening 12 through which is adapted to be extended the upper portion of the shank S. With the link or bar 10 in applied position it will be perceived that the shank S. is effectively held against any rotary movement.

The outer side portion of each of the tables T or T is provided with an opening 14 through which is extended the threaded shank 15 depending from the spreader or hobble 16 which is adapted to be connected, as at 17, with thespreader or hobble extending from a second beam B, and whereby said beams are effectively maintained against relative lateral movement. The shank 15' has coacting therewith the clamping nut 18 whereby it will be perceived that the hobble or spreader 16 is effectively held to the table T or T. v

In order to maintain the link or bar 10 against displacement, it is preferred to insert through the portion 8 of the shank S at a point above the bar or link 10 a c'otter pin 19 or the like. v

The lower ends of the shanks S and S coacting with a common beam B are connected by the ground engaging member or plate 20 through the medium of the removable bolts 21, said plate 20 having its flat faces vertically disposed and having its lower or engaging edge disposed parallelto the ground being worked. I I

To the outer faces of each of the plates 20 is secured a substantially fiat blade 22, said blade 22 being disposed r'earwardly and outwardly on a predetermined incline and having its inner end provided with an upturned portion 23 overlying the outer face ofthe plate 20 and it is to be noted that the removable bolt 27 serves as a means for securing said blade to the plate. The blade22is also further secured to the plate 20 as indicated at 28.

It is also to' be noted: that the connection between the blade 22 and the plate 20 is, adj acent the forward end of said plate and coacts with the forward shank S.

Secured to the inner face of the plate 20 adjacent the rear of said plate is a sec-- ond substantially flatbla'de 24 disposed inwardly and rearwardly on a predetermined incline and having its inner endpr'ovide'd with an upstanding extension 25 through less than the blades 22 and serve to coact with the soil immediately adjacent the opposite sides of a plant row.

As illustrated in Figs. 6 and 7 a plate 2O substantially square in form is adapted to be secured, at 21, to one of the shanks and preferably the shank S, and secured to the opposite sides of said 26* as indicated at 26 are the blades QQeand 24*, said blades being of differing lengths and disposed on prede termine'd inclines as has hereinbef'ore been set forth relative to the blades 22 and 24. It is also to be observed that the securing eans 26 are common to both of the blades 22 and 24.

From the foregoing description, it is thought to be obvious that a cultivator con-- structed in accordance'with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without'material departure from the principles and spirit thereof and for this reason 1 do not wish'to be understood as limiting myself to the precise an rangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

In combination with a beam of a culti;

vator, a plurality of shanks depending from said beam and spaced longitudinally thereof, the upper extremity of one of said shanks being angnlar' in cross section, a link provided with openings to receive theupper portions of the shanks, the'opening through which the angular portion of the last named shank is directed being of-substantially the same configuration as the cross section of said upper portion of the shank, meansdemummy disposed through the second shank.

above the link when'the link is in applied position for holding the, link against displacement, and a groundworking member connected to the lower end portion of either orboth of the shanks. V

, In testimony whereof I-hereunto afliX my signature'in the presence of two witnesses.
