SPECIFICATION forming part of Letters Patent No. 601,544, dated March 29, 1898.
Application filed July 2, 1897. $erial No. 643,276. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM H. BENNETT, of Athlone, in the county of Rockingham and State of Virginia, have invented certain new and useful Improvements in Plows and Cultivators; and I do hereby 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.
This invention relates to improvements in plows and cultivators, the object of the same being to provide improved attaching means whereby the shovel may be readily attached to the standard and removed therefrom when desired, the same being held rigidly in position by the fastening device.
The invention consists in certain novel features of construction hereinafter fully described and claimed.
In the accompanying drawings, Figure 1 is a side view of a portion of a shovel-standard, showing my improvement applied thereto, the shovel being illustrated in position upon the standard. Fig. 2 is a side elevation of the lower end of the shovel-standard with the shovel removed. Fig. 3 is an end view of the lower end of the standard with the shovel removed. Fig. etis a view of the shovel.
Referring to the accompanying drawings, 1 indicates the shovel-standard, which is provided on its opposite sides, at its lower end, with the longitudinally-extending slots 2, which form the central tongueor web portion 3. The lower end of the standard is slotted transversely, as illustrated at 4, said transverse slot communicating with the lower ends of the longitudinal slots, as illustrated. Raised from the rear side of the standard are the lugs 5, between which is pivoted the lever 6, carrying at its lower end the lockingpin 7, which extends through a perforation 8 in the rear wall of the transverse slot. A coiled spring 9 is positioned in a cavity 10, formed in the rear side of the standard, beneath the upper end of the operating-lever, against which it bears, thus serving to hold the locking-pin normally projected through the wall of the standard.
11 is a shovel provided adjacent its upper end with a central slot 12 and a perforation 13 at the lower end of said slot. This shovel is adapted to be inserted within the slotted end of the standard, the web portion of said standard taking into the slot formed in the shovel. The shovel is inserted in the standard until its perforation is in line with the perforation of the standard, the locking-pin being raised in the meantime by pressure upon the operating-lever, so that when said perforations are in line the locking pin passes therethrough, when the operating-lever is released and secures the two parts rigidly together.
The locking pin and mechanism being on the rear side of the standard does not in any Way interfere with the plowing.
I do not limit my invention as a securing means for attaching the shovel to the standard, as it may be used in many other connections-as, for instance, in securing the teeth of cultivators in position.
From the above description it will be seen that I have produced an improved locking device for detachably securing the shovel to the standard whereby the shovel may be quickly and readily removed from the standard or positioned thereon as desired.
Having thus described the invention, what a is claimed as new is 1. The combination with a slotted shovelstandard having slotted sides and end and a central web portion of a shovel provided with a slot adapted to receive the central web portion of the standard, a locking-pin adapted to project through the standard and shovel, and a spring-catch operating lever for hold-. ing said pin normally engaging the standard and shovel, substantially as described.
2. The combination with a shovel-standard having longitudinal slots formed in its lower ends on opposite sides thereof and forming a central web portion, said standard formed with a transversely-extending slot at its lower end which communicates with the lower ends of the longitudinal slots, an operating-lever pivoted to the standard, a locking-pin carried by the lower end of the operating-lever and adapted to project through a perforation in the standard, of a shovel provided at its upper edge with a central longitudinal slot to receive the central web portion of the standard and with a perforation to receive the locking-pin, and a spring positioned in specification in the presence of two subscribthe cavity formed in thelshovel-siclailllaigd and in g Witnesses. engaging the operatingever to 0 t e pin normally projected through the perforations WILLIAM BENNETT 5 of the standard and shovel, substantially as Witnesses:
described. i J. W. HINTON, In testimony whereof I have signed this GEO. W. HESS.
