ELECTRIC SWITCH.
Specification of Letters Patent.
Application filed July 6, 1915. Serial No. 38,074.
To all whom it may concern:
Be it known that we, BURTON L. LAWTON and BENJAMIN A. SPITZER, citizens of the.
United States of America, residing at Meriden, New Haven county, Connecticut, have invented a new. and useful Electric Switch, of, which the following is a specification.
Our invention relates to improvements in electric switches, and particularly to a simple form thereof, which is easy to assemble, inexpensive, durable and efiective.
In the drawings: Figure 1 is a side elevation of thecorhplete'switch. Fig. 2 is a central longitudinal section. Fig. 3 is a cross section on the line 33. Fig. 4: is an end view of the insulating block with the cover plate and switch plug removed. Figs. 5 and 6 are details in perspective. 1 isablock of insulating material having a central cavity in which are 100 ted spring contacts 22. *In'the bottom 0 the cavity is a backing shoulder 3. The lower end of each spring contact piece 2.2 has an. out wardly bent foot 4, The upper end of each of said spring contacts is .bent inwardly so that between the bent-in ends may be located and properly held aswitch plug. The switch plug preferably comprises the tapered metallic end piece 5, and the insulating shank 6.
. 7 is an annular notch in the insulation 6.
The spring contacts are held in place by an ingenious and simple combined holding means and terminal member in the form of a specially constructed tubular member 8 having a flange 9, the shank of the tubular member being arranged to passthrough a hole in the foot of its respective spring contact, and to continue on through a hole in the base or inner end of the block 1. One side of the flange is cut away so as to bear fiatwise against the adjacent upstanding part of the spring contact held thereby.
. 10 is a washer which is by preference used at the-outer end of the tubular connecting means 8. In assembling, the tubular con-' the same, but rotation is prevented since the squared shoulder on the member 8 bears against the adjacent upstanding part of the spring contact 2, which'latter cannot turn in the base, and hence, holds the member 8 against rotation, thus permitting the spinning operation to be reliably eflected. By reason of this construction atap may also form a thread to receive a binding screw (not shown) so that each tubular member 8 may perform the function of a binding post or terminal.
11 is a cover plate or escutcheon which may be secured tothe outer end of the block 1, in any suitable manner as by screws 1212. The outer end of the plug is provided with a handle 14 so that by pulling out the plug, the metallic end 5 may electrically bridgeand connect the ends of the contacts 22, or, by pushing in the plug, the insulating plug shank may be caused to rest between and electrically disconnect the two spring contacts.
The notch in the insulating shank serves to prevent the accidental displacement of the plug, and to hold the contacts in the open circuit position. The tapered metallic tip likewise is gripped by the spring contacts in such a way as'to hold the plug in the closed circuit position when the plug has been shifted manually thereto.
We have shown the invention in its presaid foot for holding said contact" against turning in said cavity, a tubular connecting member for each of said contacts, each of said members passing through said foot and through the lower end of said block and upset externally or the latter, with means for holding said tubular-member against turning relatively to its contact, said means com- I tact mounted on said base having a laterally prising a flanged shoulder at the inner end of said tubular member, said flange bearing against, that part of the contact just above said foot. I
2. In an electric switch of the character described, a block of insulating material forming an insulating base, a spring conextending foot portion engaging the base, a shoulder on the base engaging said foot portion and holding the contact against turning on the base and a tubular connecting member passed through the baseand the latsaid connecting member having a flanged shoulder engaging the contact above the;
foot portion thereof to secure said tubular ,member against turning onthe base.
BURTON L. LAWTONQ BENJAMIN A. SPITZER.
