l4 INVENTOR WILLIAM J. FASO ATTORNEY United States Patent 3,142,211 TOOLS FOR PICKING-UP, POSITIONING AND TURNING NUTS AND TIE LIKE William J. Faso, 2250 NE. 3'2nd Court, Lighthouse Point, Pompano Beach, Fla. Filed Mar. 7, 1963, Ser. No. 263,654 1 Claim. (Cl. 81-125) This invention relates to a tool for picking-up, positioning and turning nuts and the like and particularly for handling small size nuts and the like.
This application is a continuation-in-part of my application Serial No. 53,483 filed September 1, 1960, and being now abandoned.
It is an object of the invention to provide a tool adapted to handle nuts and the like made of any type of material, such as nylon, brass, copper, aluminium and steel.
It is another object of the invention to provide a tool which is adaptable as a finger wrench, a spin type wrench, a flexible wrench and a socket wrench set.
Other objects and advantages of this invention will be set forth in detailed description of the invention.
In the drawing accompanying and forming a part of this application:
FIGURE 1 is an elevational view of the invention embodied in a spin type wrench showing the nut engaging portion in section and in use;
FIGURE 2 is a cross-sectional view, on an enlarged scale, taken on the line 2-2 of FIGURE 1 looking in the direction of the arrows;
FIGURE 3 is a vertical-sectional view, on an enlarged scale, taken on the line 3--3 of FIGURE 2 looking in the direction of the arrows;
FIGURE 4 is a cross-sectional view similar to FIG- URE 2, on a larger scale, showing the position of retaining means when a nut is not engaged by the tool; and
FIGURE 5 is a vertical-sectional view, taken on the line 55 of FIGURE 4 looking in the direction of the arrows.
The invention is shown as embodied in a spin-type wrench comprising a shank 6 having a hand grip 7 at one end and the opposite end of the shank 6 being provided with an annular member 8 having a socket 9 in the outer end thereof. The internal cross-sectional shape of the socket 9 corresponds to the cross-sectional shape of the object to be pick-up, positioned and turned. In the present illustration of the invention, the object is shown as a hexagonal nut 10 and therefore the cross-sectional shape of the socket 9 is a hexagon.
An annular groove is provided on the exterior of the member 8 adjacent to the entrance of the socket 9, said groove comprising diametrical opposite portions 11 of a depth to communicate or open to diametrical opposite straight or flat portions of the socket 9. The depth of the interposing diametrical opposite portions 12 of the groove is less than the depth of the portions 11 and slightly greater than the thickness or diameter of a resilient member in the form of a split or U-shaped spring 3,142,211 Patented July 28, 1964 comprising an arcuate connecting portion 13 engaged in one of the groove portions 12 and straight portions 14 extending from the opposite ends of the spring portion 13 in converging directions toward each other and engaged in the groove portions 11 with the end sections of the straight portions 14 being bent toward each other in the arc of the groove portion 12, as shown at 15 in FIGURES 2 and 4. The convergence of the straight portions 14 causes the bent sections 15 to hug the vertical wall of the groove portion 12 with the connecting portion 13 slightly spaced from the vertical wall of the other groove portion 12 when the nut 10 is not engaged in the socket 9, as shown in FIGURE 4. When a nut 10 is engaged in the socket 9, the end sections 15 will be spaced from the vertical wall of groove portion 12 with the connecting portion 13 hugging the vertical wall of the groove portion 12, as shown in FIGURE 2.
In use, a plurality of nuts are placed on a supporting surface, such as a piece of material being secured as shown in FIGURE 1. One of the nuts is-picked-up by positioning the annular member 8 over the nut which will force the nut into the socket 9 with the diametrical opposite flats of the nut 10 impinging the straight portions 14 of the resilient member extending through the openings in the groove portions 11, as shown in FIGURE 2. After the flats of the nut 10 are impinged with the straight portions 14 of the resilient member, the nut is readily removed from the supporting surface, and placed and turned on a bolt 16.
As shown in FIGURES 1 and 3, the depth of the socket 9 is shorter than the length of the nut 10, so that the inner end of the nut will abut the inner end of the socket 9 and position the flats of the nut in impingement with the straight portions 14 of the resilient member.
Having thus described my invention, I claim:
A tool for picking-up, positioning and turning nuts and the like, comprising an annular member having a socket in one end of a cross-sectional shape corresponding to the cross-sectional shape of a nut including a plurality of angles and connecting straight walls, a circumferential groove in the exterior of the annular member adjacent to the open end of the socket and diametrical opposite portions of the groove being of greater depth and extended through the wall of the annular member at and for the entire length of diametrical opposite straight walls of the socket, and a resilient member mounted in said groove and provided with opposed straight portions positioned in the groove portions of greater depth and exposed to the interior of the socket to engage the entire length of diametrical opposite straight walls of a nut.
