' 1 claim. (o1. ietf-leer) This invention relates to blade andtool holders wherein cutting blades yare #elainped in fthe `vJe'n'ds of handles, and in particularahlder -having a socket in the "endior r'eceivingthe fshank of a blade lwith locking meansforclamping'the blade in .operative position and also having a Qbla'de storage .empartmrit 'in the *opposite eh21 hider with ahirr'd coverauda com Spring .'fo'r.resilitlywholirig ythe :kilarnpiAV andcover. I, i v The'. `ui5oe of 'this 'iveritiniis .to al'u'ndfhlieiwfo "lit" b Y storage 'space for ad'litidn'alblades.Y u vVariousdevices"havefbn, i 'ovided forhbldiiig safety razor blades andsblads df diierhttyp'e's for knives, tools and other devices, and whereas these are satisfactory for average useit' is diicult to grip the holder close to the cutting blade for accurate cutting. With this thought in mind this invention contemplates a holder having a cutting blade holding socket in a comparatively small streamlined end and a storage compartment inthe opposite end for carrying additional blades.
The object of this invention is, therefore, to provide a holder and handle for relatively small cutting blades in which the holder may be gripped comparatively close to the blade vfor accurate cutting.
Another object of the invention is to provide a holder for small cutting blades in which a compartment for additional blades is provided.
Another object of the invention is to provide a blade holder in which a shank of a blade is clamped in a socket having an enlarged-,inner end wherein projections on the shank of the blade secure the blade rigidly in the socket.
A further object of the invention is to provide an improved blade holder having a blade storage compartment therein which is of a simple and economical construction.
With these and other objects and advantages in view the invention consists of the new and useful combination, construction and arrangement o! parts as hereinafter more fully described, set forth in the claim appended hereto, and disclosed in the accompanying drawings forming part hereof, wherein:
Figure 1 is a plan view of the holder with the blade omitted.
Figure 2 is a longitudinal section through the holder showing a knife blade extending from the end thereof and with part oi' the blade broken away.
, Figure .3 is a view similar to that `shown in Figurez with part of .the han'dle broken away, the cover of the blade 'holding compartment open, and the blade released.
"Figure 4 Ais a view looking upward toward 'the under-'surface of the cover of thehld'e'r with -th'e base removed. y
Figure 5 is a plan view of the base of the holder with the cover removed. y v
Figure .is a cross section through the 'holder taken on lineV I-G of Figure 2. ,Figure 7 Ais a cross section taken on'line 1-7 of. Figure 2.
YFigure 8 is a cross section through the holder taken on line 8-8 of Figure 2. 4
Figure .'9 Iis a cross section through the holder taken online 9-5 of Figure'2.
Figure 10 is a plan view of the combination spring removed from the holder.
Figure 11 is a detail showing the shank of a blade adapted to be clamped in the holder.
Referring now to the drawings wherein like reference characters denote corresponding parts the improved blade holder of this invention includes a base IU, a cover` II, a spring I2, a thumb button I3, and a lever I4.
The base I is formed as illustrated in Figures 2 and 5 with a blade holding socket I5 in one end, a blade storage compartment IB in the other, and a spring holding recess Il in the intermediate portion. The socket I5 is formed with tapering sides providing a narrow part I8 with an enlarged inner end I9, and a shank 20 of a blade 2I having corresponding tapering sides andan enlarged end 22 ts snugly in the socket. The button I3 which is provided with a knurled outer surface extends through a slot 23 in the cover II and a plate 24 on the inner end slides over the shank 23 as the button is moved forward and locks the shank of the blade in the socket, as shown in Figure 2.
The spring recess Il which is positioned below the button slot 23 is provided with a spring holding shoulder 25, a lug 26, and a partition 21, and the spring I2 is formed with a U-shaped section through the holder 28 having converging sides that form a constricted open end, wherein as the U-shaped section snaps over the shoulder 25 the spring will be retained in position. One end 29 of the spring extends under the button I3 urging the button upward, and the other end 35 extends over the lug 26 and bears against the surfaces 3| and 32 of a hub 33 of the lever I4. The lever is pivotally mounted on a pin 34 in an opening 35 in the cover II, and with the surfaces 3| and 32 posi- 3 tionecl as shown the spring will hold the lever in either the open or closed position.
The cover I I is secured to the base I0 by screws 36 and 37 at the end in which the blade is positioned and a screw 38 in a recess 39 in the opposite end. The cover II is provided with downwardly extending pins 40 and 4I that register with openings 42 and 43 in the base. The cover is also provided with slots 44 and 45 into which the ends of the pin 34 in the hub of the lever I4 extend, as shown in Figure 8.
The outer end of the lever I4 is provided with an arcuate lip 46 that extends over the screw 38;
and as shown in Figure 2 the upper surface of the lever is flush with the upper surface of the cover, so that the lever forms a cover for the blade storage compartment I6.
With the parts arranged in this manner the shanks of blades may readily be clamped in the socket I5 and when in position the blades willy be rigidly held so that they may be used to cut with accuracy, and as the blades are Worn they may readily be replaced with new'or sharpened blades from the storage compartment. j
It will be understood that modications may be made in the design and arrangement of the parts Without departing from the spirit of the invention.
What is claimed is:
In a blade holding handle, the combination which comprises an elongated base with an enlarged outer hand gripping end and with the sides and lower surface thereof taperingv toward an opposite blade holding end, said basehaving an outer gripping surface `and an inner surface having recesses therein, said recesses including a first recess having tapering sides and positioned in the inner surface of the blade holding end to form a-blade holding socket and a second recess adjoining the first recess and adapted to receive a spring, a cover, the shape of which corresponds to that of the base superimposed upon said base and having a slot therethrough, said slot positioned in alignment with and spaced from said blade holding socket, a blade locking plate having an extended button on one end thereof slidably mounted in the cover witlr the said button positioned in the said-slot and lwith the endfopposite to that on which the button is positioned extended over said blade holding socket in the base forclamping the blade in the socket, and a spring in said second recess frictionally holdingth'e. said blade locking plate in the position of locking the blade in the socket and with the button lextendedthrough the slot of the cover.
