GULTIVATOR-FOOT.

Specification of Letters Patent. Patented I 16, 1915.

Application filed May 13, 1914. Serial No.- 838,373.

To all whom it may concern:

Be it known that I, JOSEPH C. GRAVES, a citizen of the United States, residing at Kosse, in the county of Limestone and State of Texas, have invented certain new and useful Improvements in Cultivator-Feet, of which the following is a specification.

This invention relates to agricultural implements, and more particularly to improve ments in the shovel supporting feet of cultivators.

The primary object of this invention is the provision of a novel form of foot for a cultivator, by means of which the shovels or sweeps may be quickly and conveniently attached to or removed from the culti-V vator; the object being carried out by the provision of an especially formed shovel carrying shoe which has sliding engagement with the cultivator foot and is yieldably held in engagement therewith by a coil spring and a lever carried by the foot.

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters designate like or corresponding parts throughout the several views, and in which,

Figure 1 is a rear view of the improved cultivator foot, showing the shoe and sweep attached thereto, Fig. 2 is a detail perspective view of the shovel or sweep carrying shoe, Fig. 3 is a perspective view of the lower end of the cultivator foot, and Fig. 4 is a cross sectional view. Fig. 5 is a detail peripective view of a part of the cultivator oot.

Referring more particularly to the drawings, 1 designates the foot of a cultivator shovel beam (not shown) which foot is attached to the shovel beam in any suitable manner, and it has its lower terminal end 2 bifurcated, forming side pieces 3 and 4 which have transversely extending flanges 5' The shoe 7 has a lug 9 formed therein and pro ect1ng into the recess 8, which lug-has its upper end 10 spaced outwardly from the firmly and securely against wabbling or loose movement upon the foot 2. The cross piece 11 forms a brace for preventing the side pieces 3 and 4 from closing or moving together. The recess 8, which is formed in the rear face of the shoe 7 is wedge shaped, or tapers inwardly as it extends downwardly within the shoe. so that when the foot 2 is seated in the recess and the cross piece 11 is positioned within the space 12, the shoe and the foot will be firmly connected for rigidly supporting the shovel or sweep blade 14, which is attached to the front face of the shoe 7. V

The foot 2 has pivotally journaled in the sides 3 and 4 thereof, the ends 15 and 16 of a lever 17, which lever is formed of a continuous length of metal, and it is bent intermediate its end as at 18, forming convolutions which receive a cross pin 19 therein. The pin 19 extends laterally or transversely from one arm or side of the lever to the other, and it has securely attached thereto one end of a spiral spring 20. The spiral spring 20 extends longitudinally within the recess or opening which is formed between V the two sides 3 and 4 of the foot 2, and it has its lower end detachably connected to a hook 21, formed upon the lug 9. The lever 17 has its upper connected end 22 bent as at 23, so that it will lie within the recess 24 formed in the beam 1 and will not protrude out of the beam, and form an obstruction for engagement with weeds or the like which might be uprooted by the shovel or sweeper blade 14.

When the lever 17 is operated or moved so as to assume the position shown in the drawings, the coil spring 20 will be relieved of tension, and it may be easily removed from engagement with the hook 21, which will permit of the sliding disconnection of the shoe 7 and the foot 2, when it is desired to interchange the shovel blades or place a new blade thereupon. When the lever 17 is actuated, so as to be seated in the position as shown in the drawings, or when the end is seated in the recess 2st, the spring 20 is held under tension and this prevents the sliding disconnection of the shoe and the foot, securely connecting the shoe to the foot in a downwardly yieldable manner.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that an easily and quickly detachable device for attaching shovel or sweeper blades to a cultivator has been provided, and while the preferred embodiment has been illustrated and described, it is to be understood that certain minor features of construction, combination, and arrangement of parts may be altered, should such alterations be necessary in reducing the invention to practice, provided they are comprehended within the scope of what is claimed.

What is claimed is 1. In a cultivator, the combination with the shovel supporting legs thereof, of a foot having its lower terminal end bifurcated, transversely extending flanges formed on the sides of said foot, a shoe adapted for sliding engagement with said foot and being provided with a facial recess therein and having longitudinally extending laterally projecting grooves formed therein and communicating with said recess, said grooves being provided for the reception of said transversely extending flanges so as to permit of sliding engagement between said shoe and said foot, a cross piece extending across said bifurcated portion, a lug formed upon said foot and spaced outwardly therefrom for coaction with said cross piece for limiting the sliding movement of said shoe upon said foot, and means for detachably holding said shoe firmly mounted upon said foot.

2. In a cultivator, the combination with the shovel supporting legs thereof of a foot having its lower terminal end bifurcated, transversely extending flanges formed on the sides of said foot, a shoe adapted for sliding engagement with said foot and being pro- A thereto intermediate its rigid and pivoted ends, and a hook formed upon said lugs and provided for receiving one end of said spring for detachably connecting said shoe and said foot.

In testimony whereof I aflix my signature in presence of two witnesses.
