Description

Sept'.12, 1950 G; MADSEN" I i 5 3 v DETACHABLE HANDLE scREw DRIVER Filed March 26, 1949 I the main part of a handle.
Patented Sept. 12, 1950 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to a detachable handle screw driver and the like.
It is an object of the present invention to provide a detachable handle for screw drivers and the like wherein the screw driver shanks can be replaced by one another'and wherein there is a simple detachable connection for the shank and the screw driver handle and wherein if the wood part of the handle cracks or breaks it can be readily replaced with another wood handle part.
Other objects of the present invention are to provide a detachable handle screw driver which is of simple construction, inexpensive to manufacture, consumes little space in storage, economical to use and emcient in operation.
For other objects and for a better understanding of the present invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a collective and perspective view of i the screw driver embodying the features of the present invention and with certain of the shanks lying free of the handle.
Fig. 2 is an enlarged longitudinal sectional view taken through the handle and on line 2-2 of Fig. 1. I
Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 2.
Referring now to the figures, I 0 represents This part is made preferably of light strong metal and is provided with a central squared bore l l to receive a squared attaching portion 12 of a screw driver shank 13 having a screw-engaging portion I4 on its outer end. This shank has an enlargement l5 from which the attaching portion [2 extends. A ball detent I6 is provided in the attaching portion I2 and will enter an opening I! in the main handle part ill to prevent the axial displacement of the shank from the part II). Connected to the main part In and extending upwardly therefrom is a rod portion 18 having a threaded opening IS in its upper end and two vanes diametri- 2 from by a plate 22 extending over the end of the part 2| and a bolt 23 having a rounded head 24 forming the end of the screw driver handle is threaded into the threaded opening of the rod l8. Should the wood or plastic part 2| become broken, it is an easy matter to remove the bolt 24 and the plate 22 to replace the part 2|.
It will be understood that the screw driver shanks can be of any shape as long as they have the same type of attaching portion and may conform to shapes 25 and 26 lying free of the handle and as shown in Fig. 1.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
Having thus set forth and disclosed the nature of my invention, what is claimed is:
A screw driver or the like device comprising a main handle part having a central squared opening, a, screw driver shank having an attaching portion adapted to fit the squared opening of the handle part in a removable manner, a rod portion extending upwardly from the handle part, a threaded opening, a vane extending laterally from the'rod projection, a second handle part surrounding the rod projection and having an opening receiving said vane. whereby to be held against rotation upon the rod projection and means connected to the upper end of the rod projection to prevent the axial displacement of the second handle part, and said means for retaining the second handle part in place on the rod projection comprising a bolt and said upper end of said rod projection having a threaded opening receiving said bolt.
