' SUBSIATION TELEPHONE INSTRUMENT.
Original application filed April 5,
The present invention relates in general to a switch hook support for substation tele phone instruments, but more particularly. to an improved type of switch hook support having as the principal object the provision of a unitary structure that is simple and compact and which will be efficient in op eration. i
This inventionvis a division of our parent case Patent No. 1,590,355 issued June 29, 1926. f
The features of the invention will become apparent upon a further perusal of the spec- V ification and will be explained fully hereinafter, reference being had to the accompanying drawings comprising Figs. 1 to 4 inclusive. These drawings show various viewsof the automatic wall substation telephone set, embodying the improved type of switch hook support. wall telephone showing the switch hook in its relative position on the telephone and also the calling and talking instrumentalities; Fig. 2 being a frontview of the telephone looking from the left hand side of Fig. 1; Fig. 3, a front view of the switch hook support as a unit separated from the telephone; while'Fig. 4 shows the inside of the cover of the telephone showing how the switch hook support is fastened to the cover and also its relative position therein.
The switch hook 6, and the springs to, 73, inclusive, which are controlled by it, are shown in Fig. 4: in the position they assume when the receiver is off the hook, the switch hook6 being held up'by the tension of the heavy spring 7 0 through the medium of the insulating bushing 69. The switch hook support 67 comprises an iron frame having a downwardly extending portion for mounting'the springs 70 to 73, inclusive, and a numberof turned up extensions which serve to mount the support onto the cover 3 vof the telephone by means of the screws 10 and 11. The switch hook is pivoted in the support by the screw 68 asis most clearly seen in Fig. 3. In this figure, it will be noted that this extension of the switch hook support 67 into which the screw 68 is screwed is seemingly longer than necessary. This extension is purposely made long so as to enable the screw 68 to be turned out far enough to permit the removal of the switch hook 6 V ATE,"
Fig. 1 being a side view of the .gomg, I will now b 1e22, eel-m1 No. 549;7sa Divided and this application filed February s, 1926. Serial No.'86,911.R-. r @i before all the threads of theiscrews are dis engaged from the extens on. Inthismanner the screw does not have-Ito be entirely -removed from the support 67 to dismount the sw tch hook 6 and thereis not; danger of lo'smg it.
1 The switchhook 6 extends through an opening in the telephone cover 8 and also through a hole in the support 67 so that when the screw 68 isthreaded through the 2 long extension of the support, the-extended portlon of the screw which is not threaded .will act as the pivot for the switchhook,
while two upturned extensions of the support serve as bearings for the screw 68. The movement of the switch hook is lim ted by the T-shaped end of the hook striking" against the flat side of the bracket 67.
-The set of springs/7O to 73, inclusive, are
fastened to the support 67 by means of a.
couple of screws, the springs being suitably insulated from eachother and the support.
The features of the invention, having been described and ascertained in the forepointed out in the appended claims.
What is claimed is:
1. Ina subscribers telephone set, a switchhook mounting bracket, said bracket comprising a perforated frame portion and three parallel members extending at right angles theretogtwo of saidinlembers being located on opposite sides of the opening in said frame and being relatively close together. :1 hook extending through said opening and between the members on'opposite sides there of, and a pivot screw having an extension passing through holes in said hook and the. said members adjacent thereto and having a relatively long threaded shank engaging a threaded hole in the other member.
2 In a subscribers telephone set, a. switch hook mounting bracket comprising a pl'ur'al ity of extension members, an opening insa1d bracket, three of said members arranged parallel to each other and extending atrig'ht angles to said bracket, two of the members being located on opposite sides of said open ing, a switch hook extending through said opening and between the members on opposite side thereof, a pivot screw having an ex tension passing through-holes in said switch hook and said members adjacent thereto and ing a T-shaped end extending thr Y having" a threaded shank engaging a hole 111 said other member, a spring combination mounted on the end of a long one oi said ex tension members a and arranged parallel thereto, one of "the springs. bearing ,on the end of said switch hook to move it .whenthe receiver is off, and two other of said extension members extending at right angles to said bracket and bent parallel thereto at the ends iorlmounting the whole of said bracket on the wall of said telephone set.
3; In combination with a subscribers telephone set, a switclrhook mounting bracket comprising a plurality of extension members and an opening therein, a switch hook havgh said opening, three of said n'1eml')ers arranged at right angles to said bracket and parallel to 'and'an opening therein, a switch hoolnhaving; a T-shaped end extending through said opening, three of said members arranged at right angles to said bracket and parallel to each other, a pivot screwextending through holes in said members and said switchhook and threaded in only one of said members,
the movement of said switch hook around said pivot screw, being'limited by said bracket, and two other of said members ar ranged on opposite sides ot said switch hook and bent at right angles and attheends parallel to said bracket,"formounting said bracket and switch hook on thewall of said telephone set, V
5. In combinationwith' a'subscriber s telephone set, a switch hook mounting bracket comprising a plurality of extension members and an opening therein, a switch hook having a T-shaped end extenclingthroughsaid opening, three of said members arranged at right angles to said bracket and parallel to each other, a pivot screw extending through holes in said members and said switchhook and threaded in only one oi said members, the movement of said switch hook around said pivot screw, being limited by said bracket, and a spring combination"mounted.
on another of said members, one of. said springs being in operative relation to the T-shaped end of said switch hook to move it when the receiver 1s removed.
In witness whereof, I hereunto subscribe 7 my name this 27th day of January, 1926. i I a i i V Jo-nu ERICKSON.
