5 Claims.

The present invention relates to mountings for telephones and, more particularly, to desk mountings for hand telephones.

A mounting of this type conventionally comprises a supporting base, a pedestal carrying a calling dial, and a cradle provided with a switchhook and adapted to support ahand telephone or hand set of the well-known monophone type; the usual substation apparatus, including an induction. coil, a condenser, a signal bell and a switching mechanism, being housed in the supporting base and pedestal of the mounting.

It is an object of the present invention to provide a mounting of the type described which is of simple and rugged construction and which embodies an improved arrangement for facilitating movement from place to place of the mounting and the hand telephone supported thereby.

Another object of the invention is to provide a mounting of the type described which embodies an arrangement for latching the handle of the hand telephone securely in place in the cradle of the mounting in order to prevent operation of the switching mechanism housed in the mounting incident to the movement from place to place of the mounting and the hand telephone supported thereby.

The objects set forth above are attained in accordance with the present invention by providing a mounting of the character described comprising a base, a pedestal and a cradle including two spaced-apart and upwardly extending cradle members, the pedestal including front and rear upwardly and inwardly extending walls and upwardly extending side walls formed by the cradle members. The rear wall of the pedestal and the cradle members are so constructed and arranged that a substantially channel-shaped recess is provided in the rear of the pedestal, the cradle members being provided with aligned cradle seats therein adapted to support the handle of the hand telephone. An element having a body portion and extending between the cradle members is pivotally mounted on the cradle members immediately below the plane of the aligned cradle seats provided therein. The element has a normal position wherein the body lid portion thereof is disposed below the plane of the aligned cradle seats provided in the cradle members and in the recess provided in the rear of the pedestal and an operated position wherein the body portion thereof is disposed above the plane of the aligned cradle seats provided in the cradle members and in latching engagement 1939, Serial No. 267,821

with the handle of the hand telephone, thereby to latch the handle of the hand telephone securely in place into the aligned cradle seats provided in the cradle members. The element is so constructed and arranged that the body portion thereof is readily accessible when it occupies its normal position, thereby to accommodate rotational movement of the element from its normal position to its operated position. The hand telephone and the mounting are so constructed and arranged that the hand telephone and the mounting are movable as a unit from place to place by the handle of the hand telephone when the handle of the hand telephone is latched in place in the aligned cradle seats provided in the cradle members. Also, switching mechanism is arranged within the mounting and a movable member is associated with the cradle and operatively connected to the switching mechanism. The cradle and the member are so constructed and arranged that the switching mechanism is controlled in accordance with placement and removal of the handle of the hand telephone with respect to the cradle. When the handle of the hand telephone is securely latched in place in the cradle, operation of the switching mechanism incident to the movement from place to place of the mounting and the hand telephone supported thereby is positively prevented.

The novel features believed to be characteristic of the invention are set forth with particularity in the appended claims. The invention, both as to its organization and method of operation, together with further objects and advantages thereof, will best be understood by reference to the following specification taken in connection with the accompanying drawing, in which Figure 1 is a perspective view of a mounting for a hand telephone which is constructed and arranged in accordance with the present invention; and Fig. 2 is a longitudinal sectional view of the mounting shown in Fig. 1 and a hand telephone supported thereby, illustrating the operated position of an element of the mounting and the substation apparatus housed therein.

Referring now more particularly to the drawing, there is shown a desk mounting or support it) for a hand telephone or hand set of the wellknown Monophone type illustrated at H, which mounting comprises a supporting base H, a pedestal I3, and a cradle l4 including two spacedapart and upwardly extending cradle members 15 and IS. The pedestal I3 is provided with front and rear upwardly and inwardly extending walls I1 and I8 convergin slightly forwardly of the cradle I4, a top wall I9 extending between the front and rear walls I1 and I8, respectively, and upwardly extending side walls formed by the cradle members I5 and I6. The top and rear walls I9 and I9, respectively, of the pedestal I3 and the cradle members I5 and I6 are so constructed and arranged that a continuous substantially channel-shaped recess 20 is provided in the top and rear of the pedestal I3. Aligned cradle seats 2| and 22 are provided in the cradle members I5 and I6, respectively, the cradle seat 2| provided in the cradle member I5 being formed therein by spaced-apart and upwardly extending front and rear tines 23 and 24, respectively; and the cradle seat 22 provided in the cradle member I6 being formed therein by spaced-apart and upwardly extending front and rear tines 25 and 26, respectively. The cradle seats 2| and 22 provided in the cradle members I5 and I6 are provided with recesses therein into which two mental inserts 21 and 28, respectively, are securely positioned, the inserts 26 and 21 having openings therein into which two switchhooks or plungers 29 and 30, respectively, are slidably mounted.

The front wall H of the pedestal I3 is provided with an annular recess I'I therein within which a calling dial 3| is positioned and supported in place. The interiors of the supporting base I2 and the pedestal I3 are hollow in order to provide a continuous cavity 32 therein which accommodates the usual substation apparatus such as a signal bell 33, an induction coil 34, a condenser 35 and a switching mechanism 36, the switching mechanism 36 being operatively associated with the switchhooks or plungers 29 and 30 by a suitable connecting lever mechanism 3I. The opening into the cavity 32 formed in the supporting base I2 and the pedestal I3 is closed by a suitable base plate 38 fastened to the supporting base I2. Also, the mounting I is so constructed and arranged that the center of gravity thereof is disposed in a substantially vertical plane extending through the aligned cradle seats 2| and 22 provided in the cradle members I and I6, respectively, in order to insure proper balance of the mounting.

The handle of the hand telephone II is supported in the aligned cradle seats 2| and 22 provided in the cradle members I5 and I6, respectively, the weight of the hand telephone being adequate to retain the switchhooks or plungers 29 and 30 in their depressed positions against the bias of the'switching mechanism 36, in order to retain the switching mechanism 36 in its open circuit position in a well-known manner. When the handle of the hand telephone II is removed from the supporting cradle seats 2| and 22 provided in the cradle members I5 and I6, respectively, the switchhooks or plungers 29 and 30 are projected outwardly under the bias of the switching mechanism 36, in order to cause the switching mechanism 36 to be operated to its closed circuit position in a well-known manner.

In order to facilitate movement of the mounting III and the hand telephone II supported thereby from place to place, an arrangement is provided which comprises a resilient metallic element 39 provided with a body portion 40 and two outwardly extending pivot pins II and 42 arranged in aligned openings provided in the inserts 21 and 28, respectively. Accordingly, the element 39 extends between the cradle members I5 and I6 and is pivotally mounted in the aligned openings provided in the inserts 21 and 28 carried by the cradle members I5 and I 6, respectively. The element 39 has a normal position wherein the body portion 40 thereof is disposed below the plane of the aligned cradle seat 2| and 22 provided in the cradle members I5 and I6, respectively, and substantially entirely in the recess 20 provided in the rear of the pedestal I3. Also, the element 39 has an operated position wherein the body portion 40 thereof is disposed above the plane of the aligned cradle seats 2| and 22 provided in the cradle members I5 and I6 and in latching engagement with the handle of the hand telephone II. The element 39 is so constructed and arranged that the body portion 40 thereof is readily accessible when it occupies its normal position, thereby to accommodate rotational movement of the element from its normal position to its operated position. When the element 39 occupies its operated position, the handle of the hand telephone II is securely latched in place in the aligned cradle seats 2| and 22 provided in the cradle members I 5 and I6, respectively, thereby to prevent operation of the switching mechanism 36 housed in the cavity 32 provided in the pedestal I3 incident to the movement from place to place of the mounting I0 and the hand telephone II supported thereby. Also, it is noted that the element 39 is so constructed and arranged that when it is moved from its normal position to its operated position, the body portion 40 thereof is sprung over the top portion of the handle of the hand telephone II, thereby to clamp the handle of the hand telephone II securely in place in the aligned cradle seats 2| and 22 provided in the cradle members I5 and I6, respectively.

The hand telephone II and the mounting I0 are so constructed and arranged that the hand telephone II and the mounting I 0 are movable as a unit from place to place by the handle of the hand telephone II when the handle of the hand telephone II is latched in place in the aligned cradle seats 2| and 22 provided in the cradle members I5- and I6, respectively. It is contemplated that the person desiring to move the mounting I0 and the hand telephone II supported thereby from one place to another will first grasp the body portion 40 of the element 39 and rotate the element 39 in a counterclockwise direction about the pivot pins 4| and 42, as viewed in Fig. 2, from its normal position to its operated position, thereby securely to latch the handle of the hand telephone II in the aligned cradlev seats 2| and 22 provided in the cradle members I5 and I6. The person may then conveniently move the mounting I0 and the hand telephone II supported thereby from one place to another by inserting his fingers in the recess 20 provided in the rear of the pedestal I3 and gripping the handle of the hand telephone II. When the mounting I 0 and the hand telephone supported thereby are thusmoved, the hand telephone II is moved directly and the mounting I0 is secured fastened to the handle of the hand telephone II by the element 39 as previously explained.

In view of the foregoing, it is apparent that a desk mounting for a hand telephone is provided which is of simple and rugged construction and which embodies an improved arrangement for facilitating movement from place to place of the mounting and the hand telephone supported thereby and for preventing operation of the switching mechanism housed in the mounting and operatively associated with the cradle of the mounting incident to the movement of the mounting and the hand' telephone supported thereby.
