UNITED STATES PATENT OFFICE.
CHARLES W. BROCKETT, OF WHITE PLAINS, NEW YORK, ASSIGNOR TO W. QSTR'AN- DER & COMPANY, OF NEW YORK, N. Y., A. CORPORATION OF NEW YORK.
ELECTRIC SWITCH.
Specification of Letters Iatent.
Patented Nov. 9, 1920.
Application filed September 6, 1919. Serial No. 322,074.
1 0 (ZZZ whom it may concern Be it known that 1, CHARLES W. BnooK- n'rr, a citizen of the United States of America, residing at White Plains, New York, have invented a new and useful Electric Switch, oil? which the following is a specification.
My invention relates particularly to a switch for what are commonly termed pull sockets.
The invention is directed particularly to the spindle and its attachments. The main object is to provide a simple and inexpensive method of securing the spindle to one oi the porcelain parts. Another object is to simplify and cheapen the method of. securing the upper end of the spring.
In carrying out the invention the porcelain base is provided with a passage for the spindle and a recess surrounding the opposite ends of this passage. Metal Washers are located on the spindle in this recess and one oi the parts is angular in section and corresponds in shape with the surrounding porcelain, so as to prevent relative rotation. Yielding washers are interposed between the metal washers and the porcelain so as to makeit possible to hold the parts securely without breaking the porcelain. The spindle nut or upper spring abutment is in the form of a slotted disk, embracing a slotted portion of the spindle and notched to provide a plurality of shoulders for engagement of thespring.
Figure 1 is a side view and partial section of the parts of a switch embodying my invention.
Fig. 2 is a plan View showing the spindle and spring abutment.
Fig. 3 is a bottom plan view of the base showing the spindle anchorage.
Fig. 4 is a perspective view of the parts of the spindle and its connections.
Fig. 5 is a perspective view of a modified form of spindle.
The insulating base 5 is usually made of porcelain and carries one or more stationary switch contacts. The spindle 6 is secured to the base as will more fully hereinafter be described. The member 7 is mounted on the spindle 6 and carries a rotary switch member of any suitable construction (not shown). The ratchet lever 8 is adapted to be oscillated by a chain or in any other manner so as to rotate the carrier 7 step by step.
A spring 9 surrounding the spindle has the end 10 engaging the lever 8 and the end 11 engaging an abutment plate or disk 12. T he latter has a central slot 13 with a flaring entrance 14. at one side so that it may be readily slipped on to the end of the spindle and seated in the grooves lo -15. The disk 12 is preferably provided with a series of notches 1616 which afi'ord convenient places for engagement of the end 11 of the spring so that the spring may be adjusted to any desired tension. By locating the notches 16 adjacent the closed end of the slot 13 opposite the entrance 14, the disk is weakened at these points so that the ends of the disk adjacent the entrance-14 may be more readily bent in to clamp the spindle.
The base 5 is provided with a central passage 17 with recesses 18 and 19 on the opposite faces. The passage 17 is prefer ably somewhat larger than the corresponding part of the spindle so as to allow for variations inthe size of the passage such as occur in the ordinary manufacture of porcelain parts. The recess 18 is large enough to conveniently accommodate the metal 'washer 20 which fits on the central part of the spindle against the shoulder 22 formed by flattening the lower end of the spindle. This washer 20 forms a shoulder which is large enough to aflord a proper support for the spindle at the upper end of the passage 17 even though the passage may be somewhat larger than necessary. Instead of providing a separate washer 20 for forming the shoulder, the center of the spindle may be upset as at 20 in Fig. 5 to form an integral shoulder. At the bottom of the recess 18 I preferably insert a yielding washer 23 of fiber or other suitable material. Another similar washer 24 is interposed between the metal washer 25 and the upper wall of the recess 19. When the parts are assembled, the-lower end of the spindle is upset or riveted over so as to permanently hold the spindle inplace. The fiber washers afford yielding seats for the metal washers or shoulders so as to permit the parts to be secured together tightly and snugly without. fracturing the porcelain. To prevent relative rotation of the spindle with respect to the base the washer 25 may be provided with an elongated opening 26 to connect it in a non-rotative manner with respect to the spindle and it may be itself angular in shape and seated in acorrespondingly shaped recess 19 in the underside of the base. The spindle shoulder 20 in the modification of Fig. 5 may be angular in cross section, for instance, square, and seated in a corresponding shaped recess 18 so as to prevent rotation of the spindle in the base.
According to this invention, the porcelain may vary considerably in size or even be somewhat warped and yet it will be possible to securely fasten the spindle in position without breaking the porcelain.
I claim:
'1. In an electric switch of the character described, a. porcelain body having a passage therethrough and recesses on opposite faces surrounding the ends of the passage, one of said recesses being angular in shape, a spindle extending through said passage and having metal washers in said recesses and yielding washers interposed between said metal washers and the walls of the recesses surrounding the ends of said passage.
2, In an electric switch of the character described, a porcelain body having a passage therethrough, a recess on one face at the entrance to said passage, a spindle in said passage, metal washers on said spindle on opposite faces of said body, one of said washers being angular in shape and located in said recess, and yielding members interposed between said washers and said porcelain body, the end of said spindle adjacent said angular washer being upset or riveted.
3. In an electric switch, a porcelain body having a passage therethrough having a recess on its lower face surrounding the entrance to said passage, a spindle extending through said passage and having a flattened portion, said spindle having a shoulder overstanding the edges o1 said passage at its upper end, a yielding washer interposed between said shoulder and the porcelain, and a washer riveted 011 to the flattened end of said spindle in said recess.
4. In an electric switch, an insulating base having a passage and recesses at opposite ends of the passage, a spindle having one end flattened and extending through said passage, metal washers on the flattened end of said spindle in said recesses and yielding material interposed between said washers and the insulating material.
5. In an electric switch, an insulating body having a spindle passage with I washer recess at the entrance thereto, spindle extending through said passage, washer 011 said spindle in said recess, metal. washer secured on the end of said s )lIlCllG and a vieldin washer inter osed between said metal washer and said body and having a portion extending into said passage around said spindle.
6. In an electric switch, an insulating base, a spindle ri idly secured thereto, an oscillating operating lever mounted onsaid spindle, the outer end of said spindle being slotted, an abutment disk having an elongated central slot engaging the slotted portion of the spindle, said slot opening on one edge and said disk being provided with notches adj aeent the oppositeend of the slot and a spring surrounding the spindle having one end engaging said lever and the other end adapted to engage in either one of said notches or in the entrance to said slot.
