proved tool-holding device, showing the tool' in position;

Fig. 2 is a vertical sectional view;

Fig. 3 is a detached perspective view illustrating details of the invention;

Fig. 4 is a sectional view of the device arranged to display drills and their hits;

Fig. 5 is a view illustrating a modification of the invention; 7

Fig. 6 is a perspective view of another modification; and

Fig. 7 is a vertical sectional view of the device shown in Fig. 6. j

On a base 1 of any suitable form ismounted a tool-holding device 2. This device has a threaded opening at itslower end to receive the threaded portion of the retaining screw 3, which extends through an opening in the base 1. The screw in the present instance has an annular groove 4, in which is a washer 5 resting in a recess in the underside of the base. In the upper end of the retaining screw 3 is a socket 6, in which is located a freely rotatable plug 7, having a transverse slot in its upper end to receive the bit of a screw-driver.

At the upper end of the tool-holding device is a bearing 8 for the shank 9 of a screw-driver bit 10, in the present instance.

On the shank directly under the bearing is a collar 11 secured to or forming part of the bit. The blade of the bit extends into the slot in the plug 7, and the collar is so located as to retain the blade in engagement withthe plug at all times. A portion of the tool which actuates the bit is shown at 12, and in the present instance is a push screw-driver.

To operate the push screw-driver, it is pushed to turn the bit which also turns the plug. A spring in the screw-driver returns DISPLAY 'roo'L- HOLDER;

the handle end ofthe driver to its normal position as soon as it is released. The bit can be turned to the right or left by moving the shifter 13. This type of screwdriver is one of many different types now on the market.

If a push-drill is to be displayed, then the bit 10 is in the form of a drill bit, as shown in Fig. 4;. The end of the bit rests in a conical recess 6 in the lower end of the display device, the upper end of the bit extending through a bearing 8 The bit is provided with a collar 11*, as in Fig. 2. The device 2 has an extension 3 locatedin an opening in the base and is held in place by a screw and washer.

Fig. 5 illustrates a modification, in which the display device is arranged to be secured to a base or other support by ordinary wood screws, and in the bottom of the device is a cylindrical support 3', for a plug 7 having an enlargeclhead which is slotted to receive the blade of the screw-driver. In this case, the bit 10 is held in place by the enlarged portion of the bit, the bit being passed through the opening for the cylindrical supports 3 before the support is in position, and prior to the attachment of the device to the base.

In Figs. 6 and 7 are shown modifications, in which the bearing 8 has a circular open ing for the bit, and slots at the opposite side of the opening to allow the wide portion of the bit to pass through the opening. When the bit is in place, it is difficult to remove it, as the Wide portion of the bit must be brought in exact alignment with the slots. The plug 7 in this instance has a flange at its lower end, and the opening for the plug has an internal flange. Between the two flanges is a spring 14, which places sufficient friction on the plug to allow a ratchet IOU through the base and into the threaded opening of the tool-holder, said screw having a socket in its upperend; a plug located in the socket; the bearing and the plug arranged to receive a bit which extends through the bearing and engages the plug; and means for retaining the bit in engagement with the plug.
