I Heretofore push buttons of the directory" type have employed metal face plates over i lying the whole face of the base block, and provided with recesses for the push buttons and index 1 cards, or similar constructions which usually requiredsthe use of special tools for makingalterations in the index cards,

and were expensive and parts employed; I

The present inyention aims to provide a simpler and more economical assembly,

wherein individual index "cardholders are employed in combination with an insulating base-bloclgwith features to facilitate the insertion and removjalof the index cards foralteration {when deslred, all as, hereinafter.

described in greater. detail. In the draw.- ings'' Fig-1 a plan view ofa'push button-as- 1 sembly constructed in accordance with the.

invention, one of the index cards and its holder being removed. I Figs. 2 and 3 are'sections-taken respectively on lines 2-2 and 33 of Fig. 1. p v Fig.4 is a perspective view ofv oneof the index cardholders. j l Fig. 5. is a perspective, view of a spring preferablyemployedin conjunction with the index'cardholder.

'lnaaccordance-withthe present invention a base block 1 preferably of molded insulating material such as bakelite, .is employed and provided with a row of holes 2 2) e for receiving push buttons, 8, and a recess 4 for receiving a suitablecircuit making and breaking mechanism actuated by the push buttons,-which-mechanism is not illustrated I or describedherein, assuit-able mechanisms for the above purpose are well known in the art.

The base block 1 is provided with s plurality ofdepressions'or recesses 5 which are;

respectively alined with the holes2 and each 7 of such recesses receives an individual me-f talhc index. card holding, frame 6 n such manner that the frame gives the appearance of being inlaid into ,the insulating material.

The recesses 5 and-likewise the frames 6 are open-ended,zpreferablyat their ends res mote from the push buttons; in suchmanner complicated as to; p p 7 I .7 s a i The bottom'zof each recess 5niay beeprovided 1 with a notch lO to receive the bent end 11 of the springto hold the latter inposition while V s Ibex-corresponding index card is being: re L that the indexcards 7 can be readily" slipped into orout of the frames whenever desired.

Preferably a transparent sheet 8 of pyroxw 5, to hold theind ex cards firmly in position.

moved.

ears 12 passing throughholes 13, in the base block 1, and turned over as shown; in' Fig. 3 to lock the'frames 6 in position;

A construction of. thev above nature involves the'use of much less metal than has been eniployed'heretofore in directory type u'shljbuttonsfis much 'simpler in respect'to I p. the parts necessary tobe employed, anden fables theindex cards to be inserted and'reinevedwithlgreater facility. I p i f As enother feature of the-invention I may employinrlconnection withthe baseblockl, a

bottom" closure member or' pad which has parts detachably'h'olding it in position, pref erably with'asnap engagement.- In'the illustrate'diform lot the invention I this bottom closure member consists of a; metal plate 14:

having a soft facing "15 of rubber or the like,

tongues 16 being struck inwardly from plate The frames 6. also'niay be provided with 14 at its opposite ends, and engageablebey hind shoulders 17 in spring-fingers 18 at-' tachedto therbase block. Thus the closure member may be readily pried loose, whenever access is desired to-the interior of the 7 base block for changing electrical connecg tions or other purposes, and the closure mem-' ber will snap into position when forced againstthe base block. I

I While s specific embodiment of the invention has beendescribed it should be under s p stood that changes may bemade therein without departing from its features as set forth inthe appended claims. V

Iclaim:

v 1.,- A s directorytype push button assembly including an insulating base blockhaving a row of push button receiving openings therein, said block being also provided with a plurality of recesses respectively alined with said holes, individual frames for receiving 1 5 directory cards seated respectively in such recesses, said frames and recesses being openended.

2. A directory type push button assembly including an insulating base block having a row of push button reeeiving openings therein. said block being also provided withmplu- I rality of recesses respectively alined with said holes, individual trames for -receiving directory cards seated respectively in such recesses, said frames and recesses being openended, and said frames having vDarts interr hackipgwith the blockto holdthe, frames in P ace- 3. 'A directory type push button assembly including an insulating base block' having a row of push button receiving openings therein. said block being also provided with a plurality of recesses respectively ialined with said holes, individual frames for receiving directory cardsseatedrespectively in su ch recessesr said frames and recesses beingv openended, leaf springs interposedlbetweenthe frames and the base block, the base blockand springs having parts engaging "to :hold the springs in place. i

(1 A-directory type push button assembly including an insulating'basei block having a row of mrshbntton receiving openings therein, said blockbeing, also provided with, a J! pluralitv of recesses respectively alined with said holes, individual frames for receiving directory cards seated respectively .in such recesses, said frames andrecesses beingopenended at their end-remotefrom thepushsbllt- 4 tons, the base block being hollow mdebeing provided withholes extending fromrth h ttoms of said recessesrto the interior .ofthe base block, and said frameshaving-: prqjections extending through said last kmentioned holes and engaging with theinterior -ofthe base block to hold the frames in place.

In testimony whereof I have signed my name to this specification. CHARLES AUTH.
