JOHN H. HENSON, OF FIREBAUGH, CALIFORNIA.
KNIFE.
Specification of Letters Patent.
Patented July 20, 1920.
Application filed August 21, 1919. Serial No. 318,932.
To all whom it may concern.
Be it known that I, JoHN H. HnNsoN, a citizen of the United States, residing at Firebaugh, in the county of Fresno and State of California, have invented certain new and useful Improvements in Knives; 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.
This invention relates to improvements in knives or pruning implements, such as shown and described in my Patent #810,678, granted to me on November 12, 1907.
The principal object of the invention is to provide a knife of the type specified wherein the blade may be more readily and easily adjusted to different cutting positions than that described and shown in the above named patent.
Another object of the invention is to provide a knife of the above mentioned type which is simple in construction, strong, durable, and inexpensive to manufacture.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a side elevation of a knife constructed in accordance with my invention, the blade being shown in one position in full lines, and in another position in dotted lines.
Fig. 2 is an end elevation thereof.
Fig. 3 is a side elevation with the clamping plate removed, the blade being disposed at right angle position to the handle.
Fig. 4 is an enlarged sectional view taken 1g. 1.
Fig. 5 is a perspective view of the clamping plate and handle.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 1 indicates the handle of my improved knife, which may be of any suitable material and of the proper size and length to adapt it for the desired use.
One end of the handle is preferably oil"- set laterally and forms a blade attaching head or portion 2, which is provided with transversely disposed passages or recesses,
one of which 3, opens longitudinally of the handle, and, the other 4, opens laterally and intersects the first named opening, these openings being adapted for the reception of the shank G of the blade 7. These passages form or provide upwardly projecting lugs 5, at its corners, the purpose of which will hereinafter be set forth. The shank of the blade is reduced relatively to the base or inner end of the knife blade so as to form shoulders 8 and 9 which are adapted to engage with the portion of the handle adjacent to whichever opening is occupied by the shank of the blade. The inner or cutting edge 1.0 of the blade is preferably curved and especially toward its base where it forms a substantially curved shoulder 11 that is adapted to be forced into engagement with the object being acted on when the handle is being pushed forward or lengthwise. The head portion 2 is formed with a perforation 12 which is adapted to register with I a perforation 13 in the shank of the blade.
In order to secure the blade in the desired position in the part 2, or rather in one of the passages 3 or 4:, I employ a clamping plate 14 which is apertured at 15 and is adapted to bear tightly on the top of the lugs 5 between which the blade or shank portion is held against rotation. A screw bolt 16 and wing nut 17 are employed, and the bolt is adapted to extend through the apertures in the clamping plate, shank portion, and blade attaching portion, which are I alined and register with each other.
It should be noted that the shank portion 6 of the blade is of substantially the same area in cross section as the passages 3 and 4., or better say the distance between the innermost points of the lugs 5, so that when the blade is inserted therebetween, it will be held against rotation or movement. The thickness of the shank 6 is equal to the height of the lugs 5 and when in operative position is flush with the tops of the lugs, thereby permitting the clamping plate to bear directly thereon and prevent displacement of the blade.
When it is desired to adjust the blade either to a longitudinal, or lateral position, the wing nut is loosened to permit the screw bolt 16, which is substantially long enough for the purpose, to be pushed outward from the portion 2 to cause the clamping plate to become unseated from the lugs 5. During this operation it will not be necessary to remove the nut. The clamping plate having been loosened, the blade can be rotated on the bolt or pin 16 without contacting the lugs, and thus changed to the desired position. Of course, when it is desired to change the blade from the right to the left as illustrated in dotted lines in Fig. 1, it will be necessary to remove the bolt and nut and reinsert the blade. Hence, it will be seen that this feature of my improved knife is important and that the blade my be readily changedto either of three positions without removal of the pin or bolt, thus saving time,
labor and loss of the pin or nut.
The handle 1 may be formed from one solid casting, but it is preferably to be in the form of a metallic shell or body, as
shown in Figs, with its end formed into a socket 187 for the reception of a wooden hanis to be taken as a preferred example of the same and that various changes in the shape,
size, and arrangement of parts may be resorted to without departing from the spirit of the'invention or the scope of the subjoined claim.
' Having thus described my invention, what yersible'blade having its inner end reduced to form a shank and shoulders, the shank being of substantially the same area in cross section as the said passages, and being adapted to fit in said passages, said shank portion being provided with a perforation adapted to register with the perforation in the head, a clamping plate adapted to bear on the upwardly projecting lugs and shank, being provided with a perforation adapted to register with the first named perforations, and a. bolt to extend through said perforations, being of a length to permit the blade to be adjusted to several positions without 7 removing the same.
In testimony whereof I have hereunto set my hand.
JGHN H. HENSON.
