Title:
ELECTRONIC HAND TOOL
Document Type and Number:
United States Patent 3844012
Abstract:
A hand tool for use in the electronic field that serves in use to close the contacts of a tube socket, to pull a tube out of a socket, to probe a printed circuit board for cracks or inferior solder connections, or to clean the pins of a tube. This electronic tool is composed of a shaped metal rod joined to a plastic handle. The cylindrically shaped rod is formed with a sharp, flat tip, with the free end of the tool formed with beveled flat surfaces that meet in cutting edges.

Claims:
Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is
1. A hand tool for use in electronic maintenance work which comprises a cylindrical rod fitted to a plastic handle, with the free end of the rod formed in a pointed, curved tip and with a cutting edge leading along both sides of the rod from the tip part towards the handle, said cutting edge formed by two flat beveled surfaces formed at the tip end of the rod with said beveled surfaces intersecting each other to form said cutting edge.
2. The combination as recited in claim 1 in which the rod is formed of stainless steel metal.
3. The combination as recited in claim 2 in which the rod is formed of tempered stainless steel metal.
Description:
SUMMARY OF THE INVENTION
My invention relates to a hand tool for use in assembling and repairing electronic assemblies.
An advantage of my invention is that it can serve alternately as tool to push the contacts of a tube socket closer together, to remove a tube from a socket, to scrape the socket pins of an electronic tube, and to probe a printed circuit board for cracks and inferior solder connections.
A further advantage of my invention is that it is small and may be carried in a user's pocket. The tool is in the form of a shaped cylindrical rod fitted to a plastic handle, with the free end of the tube formed with beveled flat surfaces that meet in cutting edges and end in a pointed tip.
BRIEF DESCRIPTION OF THE DRAWINGS
The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment of the invention, taken together with the accompanying drawings in which:
FIG. 1 illustrates an elevation of the electronic hand tool;
FIG. 2 illustrates a side view of the tool;
FIG. 3 illustrates a side perspective view of the tip of the tool;
FIG. 4 illustrates a perspective view of the electronic hand tool employed to scrape the pins of an electronic tube;
FIG. 5 illustrates a side view of the electronic hand tool employed to push the contacts of a socket close together; and
FIG. 6 is an elevation view of the tool employed to loosen an electronic tube from its socket.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1-2 illustrate the tool 10 which is fitted with a plastic handle 11 to which a metal pocket clip 13 is attached. A cylindrical tempered stainless steel metal rod 14 is fixed to the handle 11. As shown in FIG. 3, the metal rod 14 is tapered from the pointed tip 16 by two formed flat beveled surfaces 18 that lie in intersecting angled planes, and form a sharpened cutting edge 17 along their intersection.
The tip 16 of the rod 14 is curved away from the tip point, with the cutting edges 17 leading from the tip point and along both sides of the rod to the point where the beveled flat surfaces intersect the cylindrical rod wall.
The sharp pointed tip 16 and the beveled surfaces 18 enable the tool to be employed for purposes of prying, scraping and probing in the maintenance and installation of electronic components and assemblies as shown in FIG. 4, where the pins 20 of a tube 21 are scraped, in FIG. 5 where the tool is employed to pry the contacts 19 of socket 23, and FIG. 6 where the tool is employed to pry an electronic tube 21 from socket 23.
Since obvious changes may be made in the specific embodiment of the invention described herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope.
