9 Claims.

This invention relates to handles for tools and particularly for screw drivers.

It is the object of this invention to provide a transparent handle arranged to support. in-

ternally various types of media on which are printed or otherwise displayed instructions and advertising which can be seen through the transparent handle.

It is a furtherobject to provide such a handle that is so formed as to act as a. lens to magnify the printing on the inside of the handle to make it easily legible on the outside.

It is a further object of this invention to have a hollow handle in which the legends can be readily inserted and maintained in an exact position.

It is a further object to provide such a handle which is reinforced internally by ribs, which ribs are also used to position the legends inside the handle.

It is a further object to provide exterior ribs on the handle of transparent material so designed as to perform the triple function of reinforcing the handle, providing a grip for the users hand on the handle, and providing a lens for enlarging the legends of the printed matter carried within the handle and positioned by the internal ribs.

It is a further object to provide such a transparent handle with either a strip or a sleeve of material carrying legends, which material is held in position by a block that performs the triple function of closing the open end of the handle, supporting the tool, and positioning and anchoring against displacement of the printed legend on the inside of the handle. Y

It is an additional object of this inventidn to provide a groove or angularly disposed recess for retaining a legend within a handle with an arouate body of transparent plastic material having 4 optical properties so that the legend appears to be enlarged when viewed from the exterior of the handle.

Referring to the drawings in detail, I is the 30 shaft of a screw driver or any other tool which is imbedded within the moulded plug 2 that has an enlarged head 3, a shoulder 4 and a tapered plug portion 5. This tapered plug portion fits within a correspondingly tapered opening having a tapered mouth 6 in the handle body 7. This handle body has a closed end 8 at one end and an open end at the other, which is closed by the plug 2. This plug may be sealed in position by an adhesive 9. The plug is also preferably cut away, as at H), to receive the legend strip ll, against the end of which abuts the shoulder ii on the plug 2. Thus the plug acts not only as a support for the tool l, but also as a means of attaching the tool to the handle I and for holding in position the legend strip II to prevent its outward movement.

This legend strip may be of any desired material, upon which any type of printing is applied,- to either for the purpose of placing the name of the user inside the handle, the name of the manuiacturer or instructions as to the use of the tool. This plug may be permanently anchored by the adhesive 9 or it may be detachably anchored due to its wedging fit between the tapered engaging surfaces or it may be threaded in position.

' forcing rib.

The handle itself is provided with a hollow interior l3 which may or may not be used as a container for small tools, screws and the like.

The plug and the handle areboth made of transparent plastics which have optical properties comparable to glass. However, the usual plastic ls not as clear as glass and it lacks power of sharp and clear definition. To overcome this problem in connection with plastics, we use ribs H separated by grooves IS on the exterior of the handle. The outer surfaces of these ribs, at ii, are arcuate so that a lens-like structure, as at H, is provided over the legend strip I l.

The legend strip, in Figures 1, 2 and 3, is anchored between the dovetail walls l8 of the dovetail slot [9 cut on the interior of the handle. The shoulder I2 of the plug 2 prevents the strip H from leaving this slot. Longitudinally and inwardly tapered walls l8 prevent the strip ,ll

from dropping down into the space l3 inside of the handle.

If desired, the end 20 of the plug may be used to engage a cylinder 2| of printable material which carries the legend; in which event (see Figs. 5 to 7) the printed matter is preferably arranged beneath an extra large rib 22 which acts as an enlarging lens for the legend printed on the cylinder 2 l Referring to Figures 8 to 15, these modifications show the legend strip I l maintained in position with its edges engaging the side walls of the interiorly disposed reinforcing ribs 23. When three ribs are employed, there is formed a triangular space 24 within the handle, and the corners of which space engage the edges of the strip ll. Thus the ribs reinforce the handle and, at the same time, position the strip beneath the lens 22, which also acts as an external rein- In Figures 12 and 13, these ribs 23 do not meet at the center, at 25, which act as reinforcing members inside of the handle and also as positioning supports for the legend strip I I. In Figures 14 and 15, the ribs 26 extend partway into the center of the handle and terminate in an annular reinforcement 21.

It will be understood that we desire to comprehend within our invention such modifications as come within the scope of the claims and the invention.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:
