Filed June 27, 1942 Patented Aug. 8, 1944 HANDSET TELEPHONE MOUNTING Herbert F. Obergfell, River Forest, Ill., assignor to Automatic Electric Laboratories, Inc., Chicago, I1l., a corporation of Delaware Application June 27, 1942, Serial No. 448,810

17 Claims. (Cl. 179-446) This invention relates to mountings for telephonic instruments and more particularly to mountings for handset telephones adapted to be mounted in a vertical position.

7 One object of the invention is the provision P of a mounting arrangement for a handset telephone which will enable easy removal and replacement of the handset from its mounting by the user while preventing displacement therefrom under extreme conditions, such as is encountered on board ship where the telephone set may be subjected to shock, or concussions.

Another object of the invention is the provision of means for manually moving a portion of the mounting means to permit removal of the 'i handset from its mounting by the user.

A further object of the invention is the provision of locking means for positively locking the movable portion of the mounting means to prevent its movement in response to shocks or concussions thereby preventing displacement of the handset until such time as the user performs a definite unlocking manual operation in order to remove the handset from its mounting.

A still further object ofthe invention is the provision of a universal mounting means which is adjustable to different positions to accommodate several difierent types of handsets of varying dimensions.

The foregoing objects and others not men- .tionedwill be described hereinafter with ref- ;erence to the accompanying drawings, in which: 7 Fig. 1 shows a side view of the mountin for handset telephones, constructed in accordance f'with the invention and showing, in dotted outline, a handset telephone mounted thereon:

Fig. 2 shows a frontview of Fig. 1 without the handset;

Fig. 3 shows a bottom view of Fig. 1; Fig. '4 shows a top view of Fig. l; and Fig. shows a side view of Fig. 1 with the movable portion of the mounting means in its open position to permit removal and replacement of the handset.

Referring now in detail to the drawings, the I include two extensions H1 and II which extend upwardly in a vertical direction from the arms I and 8. A cross member 9 is welded to the arms I and 8-as shown. Side plates 3 and 4 are welded to base 1 and to the arms I and 8 to rigidly secure these parts together. The side plates 3 and 4 have outwardly extending portions 5' and 6 upon which the rod 12 and U-shaped spring 14 may be assembled by means of screws 13. The portions 5 and 6- each have 3 holes therein for mounting rod 12 in different positions dependent upon the type of handset being used with this mounting. In accordance with the type of handset shown in dotted outline the rod 12 is mounted in the center hole.

In handsets having smaller outside dimensions for the receiver portion 20 of the handset the rod I2 would be mounted in the holes I! while the hole l9 would be used when the receiver portion is larger than the one shown. As will be seen in Fig. 1, the U-shaped spring 14' engages the front surface of the receiver portion 20- of the handset and presses the rear outside surface of the receiver portion 20 of the handset against the extensions and l I. It-should also be noted that the arms I and 8 and their extensions 1-0 and I l are separated by a distance greater than the distance through the handle portion 21 of the handset but considerable smaller than the distance through the receiver portion of the handset. The extensions 10 and Il extend in a direction parallel with the handle and over the outside rear surface of the receiver portion 20 of the handset to permit spring 14 to press the outside rear surfaces of the receiver portion 20 against the extensions 10 and I l.

A side plate 49, shown in Figs. 2 and 3, is riveted by means of rivets 48 to theleft-hand side of base 1 Side plate 49 is made of brass and is drilled with a hole to allow the shaft 41 to rotate freely therein. A brass side plate 43 is riveted to the right-hand side of base I by means of rivets 48. This side plate is likewise drilled with a hole to allow shaft 41 to rotate freely therein. In addition side plate 43 has a portion 44 bent at right angles to plate 4-3 and is provided with a hole 45 for locking the rod 58. Portion 46 is an extension of 44 and extends at an angle, as shown, to providea frictional slide for the endof rod 50 when the rod 50 is removed from the hole 45' in portion 44 and raised upwardly. The curved end 41- is a stop for limiting the extent of movement of the rod 50 in an upwardly direction.

. A U-sha-ped channel member 33 has brass bushings 4|) provided in the outwardly turned side portions near their upper ends to permit shaft 4| to freely rotate therein. A pair of retaining arms 31 and 38 are welded to the side portions of channel member 33 and extend outwardly from base in a horizontal direction as seen in Fig. 1. A cross member 39 is welded to the arms 31 and 38, as shown, to strengthen this assembly. Arms 31 and 38 have" extensions 30 and 3| which extend downward in. a vertical direction from the arms 31 and 33. It will be noted that the arms 31 and 38 converge toward each other, as shown in Fig. 3, so that the extensions 30 and 3| are separated the same amount of distance as the extensions I and II. The distance between the extensions 30 and 3| is greater than the width of the handle portion 2| of the handset screws 65 extending through holes in member 33 into tapped holes in member 34 in the position shown best in Figs. 1 and 5.

Additional holes 6|, E2 and 63 are provided in the sides of member 33 and additional tapped holes 64 are provided in the sides of the inner member 34 to provide different positions for the inner member 34 with respect to the outer member 33 in accordance with the different types of handsets being used with this mounting. The depth of the transmitter portion 22 from the rear surface portion, shown engaged by extensions 30 and 3|, to the front portion, shown engaged by flat spring 35, determines which holes in the members 33 and 34 should be used for the particular handset being used in this mounting. For different types of handsets having less depth than the one shown, the holes 6| and54 should be used for one type, the holes 63 for another type, and the holes 62 for a still further type. The screws 60 being used in the corresponding holesfor the different positions of the inner member 34. 1

A U-shaped member52 is Welded to the righthand side of member 33 in the position shown. The turned ends 53 and 54 of member 52 are each provided with brass bushings 51 to provide a slidable fit for the rod 53 which extends through these bushings and into thehole 45 provided in the turned edge 44 of side plate 43. A pin 55 extends through the rod 50 and normally holds the coil spring 56 encircling the rod 50 slightly compressed so that the spring holds the pin 55 against the bushing 54 and the end of rod 50 extends through the hole 45 in the edge 44 of plate 43 in the normal or closed position of lower retaining assembly. A circular knob is provided on the end of rod 50 to enable the user to pull the rod down against spring tension and out 'of locking hole 45 preparatory to rotating the lower retaining assembly. V V

A shaft 4| extendsthrough the bushings 4B in the sides of channel member 33 and through holes in the side plates 44 and 49 and are held in place by means ofwashers 10 and screws 42 secured in tapped holes in the ends of shaft 4|. The entire lower retaining assembly, as shown in Fig. 5, is rotatable on shaft 4| only after the rod 50 has been manually Withdrawn from the hole 45 of end 44. The lower retaining assembly is positively locked in its closed position, as shown in Fig. 1, by the rod 50 extending into hole 45 and a manual operation of the rod 53 to further compress spring 56 is necessary before the user can withdraw the end of rod 50 from hole 45 and move the assembly to its open position, as shown in Fig. 5.

In order to replace the handset in its mounting the receiver portion 20 is hooked over the exin its closed position.

Any shock, or concussion, cannot displace the handset because the rod 50 and hole 45 positively locks the movable retaining assembly in its closed position and because the extensions |0-|| and 3D3|, bars I and 39, and members 2 and 34 with their associated springs l4 and 36 prevent sufiicient movement of the handset in any direction to displacethe same from its mounting.

In order to remove the handset for use, the user must first pull the rod 50 downwardly until the end of rod 50 is withdrawn from hole 45 and then radially rotate the rod 50 and lower movable retaining assembly in an upward direction until the turned end 53 strikes the stop 41. The knob 5| may now be released and the movable retaining assembly is frictionally held in its open position by the spring 56 pressing the end of rod 50 on the sloping portion 46 of side plate 43. The handset may now be removed from its mounting because the extensions 30 and 3| have rotated far enough to permit such removal.

The replacement of the handset automatically actuates the movable retaining assembly to its closed position where it is looked as previously described.
