- The present invention relates toimprovements intool'holders and more particularly to the type of tool holder which is adapted to hold screwdrivers and the like for grinding and similar operations.
An object of the present invention is to provide an improved structure for holding screwdrivers and the like whereby the screwdriver may be held in predetermined relation with the grinding surface to provide even grinding thereof.
A further object of the present invention is to provide a tool holder which resiliently grips the shank of the tool and is readily manipulated for the removal of the tool as desired.
Still another object of the present invention is to provide an improved tool holder whereby the tool may first be ground on one surface and then rotated through 180 for grinding of the other surface, the tool holder being effective to hold the tool in predetermined relation with a grinding stone regardless of which face is being ground.
A further object of the present invention is to provide a resilient finger actuated gripping means for the tool shank.
This invention also has for its objects to provide such means that are convenient in use,
1 Claim. (Cl. 511-221);
economical of manufacture and of relative simplicity.
The best form in which I have contemplated applying my invention is illustrated in the accompanying drawings. wherein:
Figure 1 is a perspective view of the tool holder of the present invention showing a screwdriver mounted therein;
Figure 2 is a side elevational view of the present invention;
Figure 3 is a vertical transverse sectional view taken substantially on the plane of line 3-3 of Figure 2;
Figure 4 is a vertical plan view showing a screwdriver mounted within the holder; and
Figure 5 is a vertical transverse sectional view taken substantially on the plane of line 5--5 of Figure 2.
Referring more particularly to the drawings, wherein like numerals designate like parts throughout, the numeral I0 designates generally a tool with which the tool holder, designated generally at 12. is employed. As here shown, the tool I0 is a conventional screwdriver having a shank portion H and surfaces to be ground IS.
The tool holder I2 is comprised of a supporting housing means l8 which includes an elongated fiat flange portion 20 and a reduced block portion 22 integral therewith and extending therefrom.
21 Portion=22-=is ofrsubstantially rectangular crosssection and the entire supporting housing means I8 is provided with a bore 24 extending therethrough. The bore 24 is substantially oblonglanceolate, being provided with a V-groove 26 at one side against which the shank of the screwdriver may abut. The flat elongated portion 20 is provided with bevelled surfaces 28 along its length whereby the positioning of the screwdriver with respect to the grinding stone 3!! may be effectively maintained, as seen best in Figure 3.
A finger-operated means 30 is slidably positioned on the reduced portion 22 and is formed from a substantially rectangular, hollow and open-sided metallic frame member. The fingeroperated member 30 is formed from substantially elongated side walls 32 and end walls 3'6, with the side walls 32 adapted to slidingly engage the side surfaces 34 of the reduced portion 22. The
interior of the hollow finger-operated member 30.
is of greater length than the reduced portion 22 whereby reciprocation of the finger-operated member 30 is made possible.
One of the end walls 36 of the finger-operated member 30 at the reduced portion 22 is'provided with an opening 38 in which is fixed a finger element or pin 40 having a pointed end 42. The finger 40 is securely positioned within the fingeroperated member 30 and is slidingly engaged in a bore 21 in the reduced portion 22, said bore 21 communicating with the tool opening 24. A spring 44 isv positioned between the finger-operated member 30 and the reduced portion 22, as shown in Figure 2, whereby the finger-operated member 30 is adapted to be normally positioned with the pointed end 42 of the finger 40 engaged in a recess 46 in the shank of the screwdriver Ill.
The surface 23 of the reduced portion 22 and the surface 31 of the end wall 36 of the fingeroperated member 30 are each provided with .prO- jections 48 and 50 extending therefrom whereby positioning of the spring 44 is maintained.
From the foregoing description taken in conjunction with the drawings, it is believed that the use of the present invention will be obvious and that various other uses will be apparent to one skilled in the art and, accordingly. further detailed description at this point is deemed unnecessary. Sufiice it to say, reciprocation of the finger-actuated member 30 with respect to the flat elongated portion 22 resiliently engages and disengages the point 42 from the recess 46 of the shank ll of the screwdriver, whereby the screwdriver may selectively be positioned in the tool holder or removed therefrom. The bevel of the surface 28 may be of predetermined amounts whereby the angle of grinding of the surface [6 of the screwdriver may be controlled.
Having described the invention, what claimed as new is:
A tool holder comprising an elongated rectangular block having a transverse, substantially oblong-lanceolate opening therein for the reception of a tool and further having a longitudinal bore communicating with the opening, bevelled supporting flanges on one of the longitudinal marginal portions of the block, a substantially rectangular elongated hollow frame slidable longitudinally on the block, a pin secured to one end of the frame and slidable in the bore and engageable with the tool for securing said'tool' in the opening, and a coil spring between the block and the other end of the frame for actuating said frame for engaging the pin with the tool.
