Improvements in Supports for Telephonic Instruments.
I, SAMUEL ROSENBLATT Merchant, of 82-4 Nassau Street, in the City and State
of New York, United States of America, do hereby declare the nature of this
invention, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
This invention relates to a device designed to be secured to a wall, table or other
support and adapted to support the receiver of a telephone. The support is so con-
structed that it may be brought into any desired position and that the telephone
receiver may be thus carried readily against the ear. The support is provided with
two universal joints, made with spring cushions in their sockets, so that when brought
into any position, the carrying arm of the support will not be spontaneously
displaced.
In the accompanying drawing: Fig. 1 is a longitudinal section partly in side view
of iny telephone support.
Fig. 2 is a front view of the same.
The letter a represents a rod screw-threaded at one end to carry a socket and
terminating in a ball c at the other end. The ball c is free to turn in a socket d open
at its back and provided with an internal screw-thread, that is engaged by a threaded
tubular flange of a plate g, adapted to be screwed to the wall. Within the tubular
flange f there is placed a rubber pad h, and a felt pad i, the latter bearing against the
wall, and thus pressing the rubber pad against the ball c to retain it in any position
in which it may be placed. A groove din socket d receives an inwardly projecting
rubber gasket which bears evenly against the periphery of ball c and facilitates the
turning of the latter.
The socket ó receives a ball attached to an arm / which carries a trough-shaped
shell or receiver m designed to receive the telephone receiver n.
The shell m is made of a flexible or springing material such as sheet-metal or rubber
to securely hold the receiver n in place and yet permit its ready removal. Near its
center the shell m is bulged outward to form a surrounding bead o into which the tips
of the fingers may be inserted, if the receiver is to be removed.

page_text: The socket has an internal groove to receive a rubber gasket f similar to he
socked d. It will be seen that the shell m may be readily placed in any position,
laterally or vertically and that it will be automatically held in such position.
If the joints should work loose at any time, they may be tightened up, by screwing
down the sockets b, d.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is:
1. The combination of plate y having threaded flange with socket d rod a carrying
balle and with socket b ball arm and shell m substantially as described.
ตุ
2. The combination of plate having tubular flange, containing pads h, i, with
grooved socket d containing gasket j, and with ball c, rod d, grooved socket b, con-
taining gasket and with hall k, arm l, and shell m substantially as described.
3. The combination of rod a connected by two ball and socket joints with plate g
and arm, with the trough-shaped shell m having bead o substantially as specified.
4. A telephone support consisting of two arms connected by a universal joint, one
of said arms being joined to the fastening plate by a similar joint, while the other arm
carries the supporting shell substantially as described.
