TOOL-HOLDER.
Specification of Letters Patent.
Patented Jan. 29, 1 907.
A li mo, fil d April13, 1906. Serial No. 311.485.
To all whom it may concern."
Be it known that I, WILLIAM CARMAN, a citizen of the United States, residing at Napanock, in the county of Ulster and State of My invention relates to new and useful im-' provements 1n knife structure, and more par- 4 ticularly to that class whereln a slngle handle is employed to alternately receive and retain a number of different bl,adessuch as knifeblades, screw-drivers, gimlets, and the like and my object'is to provide a device of this class which is cheap, durable, and eflicient.
A further object is to provide means whereby the blades maybe readily inserted into the handle or removed therefrom. Y
A still further object is to provide means to automatically engage a blade when it is inserted into the handle and release the same therefrom when desired.
Other objects and advantages will be hereinafter made clearly apparent and pointed out in the claims.
In the accompanying drawings I have shown the preferred form of my invention.
In said drawings, Figure 1 is an elevation of my improved knife structure With one side of the frame removed therefrom and showing a knife-blade inserted therein. Fig. 2 is a perspective view of the handle with one side section and the blade-engaging member re moved; and Fig. 3 is a sectional view as seen from line 3 3, Fig. 1.
Referring to the figures by numerals of reference, 1 is the main frame of my improved tool-holding handle, said frame being substantially L-shaped, to each side of which are secured plates 2, said plates being secured to the frame by means of suitable rivets or'the like 3. Secured to the plates 2 at their forward end is an auxiliary frame-piece 4, said auxiliary frame also being secured between the plates 2 by means ofrivets 5, the forward end ofthe main frame 1 and the auxiliary frame 4 being spaced apart to form a way 6, through which is adapted tobe inserted the shank 7 of the blade to be used, and in this instance I have shown the usual form of knifeblade 8, although it will be understood that different forms of blades are to be used. The
inner end of the shank 7 is provided with a notch 9, in which is adapted to take a detent 10, carried by the forward end of a locking lever or arm 11, said arm being pivotally secured between the side plates 2 by means of a rivet or the like 12. The extreme outer end of the locking-arm 11 is cut away to form a ledge 13, which is adapted to engage with the projecting end 14 of the frame member 1, thereby limiting the upward movement of this end of said locking-arm. The lockingarm is also provided with a groove 15, in which is seated the end 16 of a controllingspring 17, the free end of said spring resting upon the body of the frame 1, thereby insuring pressure against one end of the lockingarm. The groove 15 and the end 16 of the controlling-spring 17 are both preferably dovetailed to insure a more rigid connection therebetween. Portions of-the side plates 2 are cut away to form alining depressions 18, thereby enabling the spring-controlled end of the locking-arm 11 to be more readily depressed when it is desired to disengage the detent from the notch in the shank of the blade.
In operation the shank 7 of the blade 8 is inserted into the 'way 6 and directed inwardly until the detent 10 engages the notch 9 in said shank, when the device is ready to be applied to use, and it will be seen that by this construction said blade will be securely held within the handle. When it is desired to remove the blade from the handle or to change the blade in use for a different blade, the user depresses the spring-controlled end of the locking-arm 11 by pressing thereon, thereby elevating the detent 10 and removing the same from engagement with the notch 9, when the blade may be readily removed from the handle and a new blade disposed therein.
What I claim is 1. In a structure of the class described, the combination with a handle comprising a main frame section having a projecting end, side plates secured to said frame, an auxiliary frame-piece secured between said side plates, a locking-arm pivotally secured between said plates,'a detent at one end of said locking-arm, a ledge at the opposite end of said locking-arm, said locking-arm also having a groove therein, a spring seated in said groove and having its opposite end disposed against the frame; of a blade, ashank integral. with said blade and having a notch too therein adapted to be engaged by the detent when the shank is inserted in the way between the main frame and auxiliary frame.
2. In a device of the class described, a handle-section comprising a main frame, plates secured to said main frame, a projection upon said main frame, a locking-arm pivotally mounted between said plates, a ledge on said arm adapted to engage the projecting end of said main frame and limit the movement of said arm in one direction, a detent at one end. of said arm, and nteans at the opposite end to direct said detent into engagement with a blade.
3. In a device of the class described a handle section comprising a substantially L-shaped main frame, plates secured to said main frame, a projection upon said main frame, a locking-arm pivotally mounted be- I l l i l tween said plates, a ledge on said arm adapted to engage the projecting end of said main frame and limit the upward movement of said arm, a detent at the opposite end of said arm, a spring disposed between said lockingarm and main frame, said spring having one of its ends dovetailed to fit a dovetailed groove in said lockingarm, the free end of said spring being directed against said main frame whereby tension will be exerted upon the locking-arm and the detent directed into engagement with a blade.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WVILLIAM CARMAN.
