ple and durable in construction, involving but a limited number of parts to the end that the cost to manufacture will be low.
Other objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:
Figure 1 represents a top plan view of the implement in use cutting a carton.
Figure 2 is a bottom plan view of the implement.
Figure 3 is a side elevational view of the implement.
Figure 4 is a side elevational View of the implement shown in inverted position, as when the blade is being extended to the desired position.
Figure 5 is a section on line 5-5 of Figure 4.
Figure 6 is a longitudinal sectional view taken substantially on line 6-6 of Figure 1.
Figure '7 is a perspective view of the detent.
Referring to the drawings wherein like numerals designate like parts, it can be seen that the body of the implement may be made of wood or some plastic material and is formed to provide a holder portion 5 and a handle portion 6. The holder portion 5 is bifurcated to divide this portion into furcations a and b, numeral I denoting the slit which defines these furcations. The free ends of the furcations a, b are cut oil on an oblique as at 8, leaving a lip 9 on the furcation b. This is a guide lip which mounts the top of the carton or a side portion, as is evident in Figure 1.
A slot it! extends downwardly through both furcations a, b.
Numeral ll denotes a blade such as a safety razor blade and which ordinarily has three longitudinally spaced or positioned openings.
In assembling the cutter, the safety razor blade H is inserted into the slit 1 so that the openings in the blade are registereing with theslot ID. A bolt l2, and preferably one having a washer I3, is disposed through the slot I0 and through the intermediate opening of the safety razor blade ll.
Figure 7 shows a special detent for the blade and this consists of an oblong-shaped plate l4 having an opening [5 in one end thereof for receiving the threaded end of the bolt I2 and an elongated finger l6 extending laterally from the opposite end of the plate. The bolt 12 is disposed through the opening I5 and is equipped with a wing nut l1, after the finger I6 has been disposed through the innermost opening of the blade I l. Thus, it can be seen that the function of the bolt I 2 and finger I6 is to prevent any tendency of the blade to rotate in the slit 1.
As shown in Figure 4, the blade has been extended to the position shown in Figure 5. I-Iowever, by loosening the wing nut l1 and pushing on the bolt l2, the blade can be moved further outwardly or retracted entirely into the slit 1, as when it is desired that the implement be not used for some period of time.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. I
Having described the invention, what is claimed as new is:
A carton opener comprising a handle having a head portion, said head portion being slit inwardly from its free end, a guide lip at the free end of the head portion, a blade for disposition in V the slit, adjusting means for the blade for holding the blade in a definitely projected position, i
