WILLIAM GARMAN, 0F ELLEN VILLE, NEW YORK.
KNIFE CONSTRUCTION.
Application filed July 14, 1923. Serial No. 651,566.
To all whom it may concern:
Be it known that 1, WILLIAM CARMaN, a citizen of the United States, and a resident of Ellenville, in the county of Ulster and State of New York, have invented a new and Improved Knife Construction, of whichthe following is a full, clear, and exact description.
This invention relates to a knife construction, and particularly to that class wherein a single handle is employed to alternately receive and retain a different number of blades, such as knife blades, screw drivers, gimlets, and the like.
An object of my invention is to provide a device of this class which is cheap, durable, simple and eficient.
Another object is to provide means whereby the blades may be readily inserted into the handle or removed therefrom.
A further object is to provide means whereby the plate will be automatically engaged when it is inserted into the handle and can be released therefrom when desired.
The invention is illustrated in the drawings, of which Figure 1 is a section taken on the line 11 of Fig. 2:
Fig. 2 is a plan view showing the knife with the plates in position; and
Fig. 3 is a section taken on the line 3-3 of Fig. 1.
The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing from the spirit of the invention. 7
Referring to the drawings, 1 is the main frame of my tool handle, said frame being substantially L-shaped. To this frame are attached rivets such as 2 and 3 by means of which side plates such as 4: and 5 are fastened on opposite sides of the frame. Secured to the plates at their forward end is an auxiliary frame-piece 6 fastened to the plates by means of rivets 7 and 8. Another rivet 9 extends between the plates and rides in a slot 10 formed in the end of the frame member 1. The outer end of the frame member beyond the rivet 2 is free and, because of the character of the material used, has a certain amount of springiness or flexibility. This flexibility permits variation in the width of the channel or passageway 11 formed between the end of the main frame 1 and the auxiliary framepiece 6. Through this passagewayor channel is adapted to be inserted the shank 12 of a blade 13, although it will be understood that different forms of blades or tools may be used. The inner end of the shank is provided with a lip 14 adapted to engage a shoulder on the rear of the end of the frame-piece 1.
In order to engage the outer flexible end of the frame-piece and move it as desired, I provide an operating member 15 pivoted on a rivet 16 extending between the plates 2. This operating member is provided with a lug or projecting portion 17 bearing against the outer end of the frame-piece 1 and is held normally in the position shown by reason of the resiliency of the framepiece. However, Whenever the operating member is depressed, it will be observed that the projection 17 will force the outer end of the frame member downwardly to increase the width of the passageway 11 so that the shank 12 of the blade 13 can be removed.
The rear end of the operating member is provided with a shoulder 18 adapted to engage with a corresponding shoulder 18" on the rear upper end of the frame member 1 so that the operating member will not tend to be forced further than the normal position shown in Fig. 1.
It will be seen, therefore, that in this form of construction, which is an improvement over the construction shown in my Patent, No. 842,173, issued January 29, 1907, entitled Tlool-holder, there are a fewer number of parts which yet, however, produce an equally efiicient result, so that the knife can be made more cheaply and is much simpler in construction and operation, therefore, being less liable to get out of order.
What I claim is 1. A knife construction. which includes a frame member, a pair of plates to which said frame member is riveted along one end thereof, the other end of said frame memher being flexible, an auxiliary frame memher on said plates spaced from the flexible end of the main frame member, and an operating handle pivoted between said plates and having a portion adapted to engage the flexible end of the main frame member to move it with respect to the auxiliary frame member.
2. A knife construction which includes a pair of spaced plates, a frame member riveted thereto but having one end free, said end being flexible, an auxiliary frame member connected between said plates and spaced from the flexible ends of the frame member to provide a passage therebetween, and an operating handle pivoted between said plates and having a projection engag ing the flexible end of the main plate where-- by the passageway between the main and auxiliary frame plates is increased when the operating member is depressed.
3. A knife construction which includes a pair of spaced plates, a frame member riveted thereto but having one end free, said end being flexible, an auxiliary frame member connected between said plates and spaced from the flexible ends of the frame member to provide a passage therebetween, an operating handle pivoted between said plates and having a projection engaging the flexible end of the main plate whereby the passageway between the main and auxiliary frame plates is increased when the operating member is depressed, a shoulder on the rear end of the main frame member, and a shoulder on the rear end of the operating member to engage and restrain the operating member in a normal position.
WILLIAM CARMAN.
