Description
June 21, 1938. RQCHTE 2,121,669
PEENING TOOL Filed April 6. 1957 Ill- Patented June 21, 1938 UNITED STATES PATENT OFFICE 6 Claims.
The present invention is a tool, and relates particularly to a tool used by optometrists or jewelers in connection with the assembly of eyeglasses, and like uses.
The lens of rimless eyeglasses are usually attached to the nose or bridge mountings or to ear pieces thereof by means of a bifurcated lug or lens strap and a screw threaded thru said lu or strap and thru the lens, whereby parts are held together. These screws frequently become loose and fall out, due to constant handling of the eyeglasses or to vibration, thus permitting the lens to fall out of position or the loss of parts of the mounting.
It is the object of the present invention to provide a tool for peening-over or riveting the end of the screw to prevent it from becoming loose and falling out.
Another object of the invention is the provision of a tool of the above stated character which is extremely simple in construction, easy to manipulate and which will accomplish the desired object without injury to the lens or other portions of the glass.
With the above and other objects in view, the
invention resides in the sundry details of construction, combination and arrangement of parts hereinafter more fully described and pointed out in the appended claims.
In the accompanying drawing, which shows the "preferred embodiment of the invention as at present devised.:-
Fig. 1 is a side elevation of the tool; Fig. 2 is an enlarged elevation of the jaws of the tool, with the ends thereof shown in section to illustrate details of construction;
Fig. 3 is a section of Fig. 2 taken substantially on line 2-2 and illustrating the tool as it is applied for use, and; I
Fig. 4 is a similar view to Fig. 3 but illustrating a position of the parts of the tool while being used.
Referring specifically to the drawing in which like characters denote similar and like parts throughout the several views, l0 denotes the body of the tool which is in the form of a pair of pliers of any well known or approved construction which comprise opposed jaws a and b which may be opened and closed through the medium of handle portions 0 and d connected to the jaws respectively. In the type of pliers shown the jaws are moved toward each other when the handle portions are pressed toward each other and are separated when the handle portions are moved away from each other.
The jaws a and b of the present tool are shown as preferably spaced apart in their normal closed position, this spacing being somewhat less than the thickness of the bifurcated lug or lens strap H usually found on parts of the eye- 5 the jaws, for instance jaw a, is provided with a 10 transverse opening I3 extending from the inner face of the jaw to the outer face thereof and in which is loosely disposed and held a cap or cup i l of a diameter greater than that of the opening l3 to permit universal movement of the 15,-.
shank It in the opening l3; or other suitable connection may be provided which will permit universal movement of the cap I 4. The cap M will fit over and bear against the head of the fastening screw l5, which passes thru the strap or bi- 20 furcated lug H to hold the lens therein. The cap or cup M has a stem or shank 16 extending therefrom into and thru the opening I3 of the jaw a ,and is of a length considerably greater than the length of the opening. The cup or cap I4 is 26 held in the jaw by a disc or washer I1 secured on its free end and of a diameter larger than that of the opening l3, the diameter of the opening i3 being considerably greater than that of the stem 5.
A peening element I8 is provided on the jaw b in alinement with the opening 13 and is disposed on the inner face of the jaw. This peening element consists of a rounded enlargement having a convexed outer surface and may be semi- 35 spherical or less than semi-spherical. As an example this peening element l8 may consist of a steel rivet having a rounded head which extends thru an opening in the jaw 13 and suitably held therein by any suitable means such as at I9. The peening element is preferably immovably fixed in position, but may be removable so as to be replaced should it become worn or mutilated.
The present tool is brought into use after the lens has been placed in the bifurcated lug or strap H which may be carried by the nose or bridge piece of spectacles or eyeglasses or by the ear pieces 20 thereof, as shown in Figs. 3 and 4, and the securing screw l5 inserted thru the lug and the lens, one end of the screw being threaded in one of the bifurcated portions thereof. To use the tool the cup I4 is placed over the head of the screw l5 and the jaws of the implement closed by pressure on the handles 0 and d to bring the peening element l8 into contact with the threaded end of the screw l5 which normally projects a slight distance beyond the lug or strap Ii. By exerting continued pressure on the handles c and d of the implement and by rocking the implement about the cup member M, the peening element l8 will spread the end 15* of the screw to up-set it in such a manner as to peen it over or to form a rivet end thereon, as shown, so that the screw l5 cannot come loose and fall out of position, This rocking or peening action of the implement is allowed by the slot or opening 53 in the jaw a, which is larger than the diameter of the stem or shank E6 of the cup [4, while at the same time an edge portion I3 of the opening i3 will bear upon the surface of the cup to clamp it in position on the head of the screw l5, as shown particularly in Fig. 4.
The present implement is a very simple device for peening the ends of eyeglass mounting screws, while at the same time permitting this to be done with ease and celerity and without the likelihood of breaking the lens as the major pressure at all times is directly thru the screw and not upon the strap or lug H or the lens i2.
Having thus described the invention and the manner in which the same is to be used, it is to be understood that the invention is not limited to the specific construction herein shown and described, as one example, but, may be modified and varied to whatever form may be desired, within the scope of the appended claims.
