I, THEODORE SMITH, a citizen of the United States of America, residing at
Georgetown, Vermillion County, Illinois, U.S.A., Gentleman, 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:-
My invention relates to certain improvements in swinging brackets which have
been designed especially for use in connection with telephones, but which obviously
have a great many other uses that will be suggested by the nature and con-
struction of the device.
The invention is illustrated in the drawings by means of 9 figures, of which,
Figure 1 is a perspective showing the bracket holding a telephone transmitter
and provided with a plate for fastening it to the wall; Figure 2 is a side view
of the same showing in dotted lines a different position Figure 3 is a plan of
the device as seen in Figure 2; Figure 4 is a section in line 4-4, of Figure 2,
looking in the direction of the arrow 4; Figure 5 is a section in line 5-5 of Figure 4,
looking in the direction of the arrow 5; Figure 6 is a section in line 66, of
Figure 4 looking in the direction of the arrow 6; Figure 7 is a side elevation of
an additional improvement; Figure 8 is a plan of the latter and Figure 9 is a
section in line 9-9, of Figure 8, looking in the direction of the arrow 9.
Referring to the drawings, A represents a plate designed for attachment to
the wall or other suitable support and provided with screw-holes, a, for that
purpose. To this plate is secured a clip, B, having two sets of cars, b b¹
respectively, in which are pivoted bearing blocks, C, C₁, by means of bolts, c. c¹,
extending through the ears and blocks, and provided with nuts, 2, 3, the latter
of which is a wing-nut to be operated by hand. This wing-nut (see
Fig. 5) is journalled in one of the ears, and bears against a
washer, c, so that the washer may be clamped against the block C¹,
and the latter crowded against the opposite ear to clamp the block against pivotal
motion between the ear, b', upon the bolt, c¹. Three substantially parallel
arms, D, D1, D2, are pivoted in the blocks, C, C. preferably by means of ends
bent at right angles and riveted in upright pivot holes, d, d. 2, in said blocks.
As here shown one of the arms is pivoted in the block, C, and the other two in
the block, C, the latter two being separated by a sufficient space to give the
necessary purchase to operate the bracket. The telephone transmitter which is
lettered E, is secured to the rods by means of a base, e, on the back of which is a
clip, preferably the duplicate of the clip, B, and connected with the rods by
similar means. By this construction each one of the parallel rods has a universal
joint at each end. Each rod is out of the plane of the other two and while the
transmitter may be moved laterally, vertically or diagonally, the base, e, is kept
substantially parallel with the plate, A. and in the proper position to receive the
vibrations of the voice. If it is desirable to clamp the bracket at any desired
height the same is done by means of the wing-nut, 3, as above described.
An additional improvement is illustrated in Figures 7, 8 and 9, which adapts

page_text: the bracket to the holding of a telephone receiver, such additional improvement
consisting in securing in a plate, E', which corresponds to the base, e, of the tele-
phone transmitter, E, a double horizontal rod, F, upon which the receiver, G, may
slide back and forth and by means of which it is held in the proper position.
This enables the receiver to be moved toward or away from the wall as may be
desired after the proper vertical and lateral position has been obtained. I
recognize the possibility of great variation in the specific structure and therefore
desire not to limit my invention except as clearly set forth below.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1: A swinging bracket containing three substantially parallel arms, each one
of which has a universal joint at each end and is arranged out of the plane of
the other two; substantially as described.
2: The combination with a bracket containing three substantially parallel
arms each one of which has a universal joint at both ends and is arranged without
the plane of the other two, of an extension bearing a slide furnishing an adjust-
ment independent of the adjustment accomplished by the jointed arms; substan-
tially as described.
3: A swinging bracket containing three substantially parallel arms, each
one of which has a universal joint at each end and is arranged out of the plane
of the other two, and a telephone transmitter secured to the universal joints at
one end of said arms; substantially as described.
4: A swinging bracket comprising three or more substantially parallel arms,
pivot blocks pivoted upon each end of the arms in parallel arms transverse to the
arms, said pivot blocks being also pivoted in lines at right angles to the first
named pivots and parallel to each other; substantially as described.
5: The combination with a bracket containing three substantially parallel
arms each one of which has a universal joint at both ends and arranged without
the plane of the other two, of a plate secured to the universal joints at one end
of the arms, a guide F, extending from said plate and a telephone receiver seated
upon said guide and adapted to be adjusted along the same; substantially as
described.
