SPRING JACK.
Ap'plication'filed October 17, 1925. Serial No. 63,010.
My invention relates to spring jacks and has for its object the provision of a much simplified and improved structure of this class.
vThe jack of my invention includes a shell housing the jack spring or springs, the bore of the shell being reduced at the front end to receive a connecting plug, and a leaf spring or springs, each anchored to and with in the shell and projecting from the anchorin' a lu eiwa in contact ortion at its b b g 8 front end in register with the reduced plug spring.
The invention will be more fully explained in connection with the accompanying drawing in which Fig. 1 1s a side view of a spring jack, as I preferably construct it, shown clamped to a panel board, this figure also illustrating a connecting plug inserted within the jack and circuit wires connected with the plug and jack; Fig. 2 is a view on line 22 of Fig. 1; Fig. 3 is a view'on line 33 of Fig. 2; Fig. 4 is a perspective View of the shell and Fig. 5 is a perspective View of a pair of jack springspreferably employed in the jack.
The shell 1 is preferably cylindrical. It is provided with a shoulder 2 that is preferably in the form of a flange, at the front end of the shell, and integrally formed with the shell. The shell is exteriorally threaded as indicated at 3 to receive a nut 4 which may be clamped against the rear face of a panel board or other support 5 which is thereby clamped between the nut 41 and the shoulder 2. The bore 6 of the shell has a reduced portion 7 at the front end of the shell to receive the current conducting metallic stem 8 of a connecting plug 9. The shell is'forined with slits 10 at its rearend, these slits being arranged upon a diameter of the shell and extending longitudinally of the shell.
A pair of contacting jack springs 11 is anchored at the r-ear end withinsaid slits, the
jack springshaving laterally extending arms 12 wh ch have driving fit within these slits;
The springs have rear' extensions 13 pr'o-. ecting rearwardly beyond the shell and formed with holes 14 to receive a current conducting wire 15. The springs are formedv with body portions 16 that'engage the interior surface of the shell and which serve to align the springs in the shell. The portions of the springs which projectforwardly beyond the body portions 16 are of' reduced width so as to clear the springs from the sides of the shell to permit them to-be readily flexed apart without interferencefrom the shell when the plug is inserted between the springs, the forward plug engaging and contacting end portions of the springs being in register with the reduced plug receiving portion of the shell bore when the plug is withdrawn, as shown by dotted lines in Changes may beinade without departing from my invention. I
Having thus described my invention, I claim: I I
A spring jack comprising .a cylindrical shell having a bore and a'shoulder and formed with an exterior thread to receive a nut to clampv a support between the shoulder and nut, the bore of the sh ell being reduced, at the, front .end of the shell, to receive a connecting plug, the shell having a slitted formation at its rear end; and a. leaf spring within the bore of the shell and anchored at itsrear end inthe slitted formation and projecting toward the front end of the shellv and having a plug engaging contac'tportion at its front end-in register with tliereduced plug receiving portion ofthe shell bore.
In witness whereof, I hereuntosubscribe my name.
