This invention relates to telephone coin col
lectors, and more particularly to supporting and
positioning means for certain parts of telephone
coin collectors.
In one type of telephone coin collectoras dis
closed, for example, in the U. S. patent to O. F.
Forsberg, 1,043,219, issued November 5, 1912, a
lower housing, ?xed to a mounting plate, has
tailed description.
The invention will be better understood by ref
erence to the following detailed description taken
in connection with the accompanying drawings, ll)
in which
for the coin chute also supports a conductor ter
‘ minal mounting block. Heretofore the mentioned
devices have been supported from the walls of the
upper housing either by a plurality of brackets,
each individually formed and predeterminedly
positioned and attached to the walls of the hous
ing or a combination of such brackets and lugs,
the latter being formed integral with the hous
ing in the forming thereof. in either of the de
scribed practices for supporting the devices upon
the walls of the housing there are required ‘many
and widely different operations of production and
positioning relative to each other, as well as upon

One embodiment of this invention contem

of a pair of cooperating one-piece combination
brackets welded to inner opposed side walls of
the upper housing of the coin collector, each of
the brackets having a plurality of pressed or

struck out portions designed singly and/or in
combination to support and predeterminedly po
sition relative to each other and the housing cer
tain devices of the coin collector, such as the coin
chute, coin signaling devices, and the conductor

One of the brackets ‘ is also
believed necessary to an understanding of this
40
invention.
Referring now particularly to Figs. 1, 2 and 3
the numeral it indicates in general an upper
housing for the telephone coin collector, the
housing comprising a front wall portion it with
integral side wall portions I7 and I8 and a top
portion is, which is inclined downwardly at its
forward portion toward the front wall. The front
wall It is perforated at 22 for carrying a dial
unit of the telephone station and also at 23 for'
the securing of other ‘parts thereto. Slots 2% 50
and 25 are formed in the side wall is for a tele
phone receiver cord and receiver hook, respec
formed with a portion serving as a cord guide tively, to extend therethrough. The inclined por
and a portion which acts as a stop surface for tion of the top 19 is provided with an elongated

for a coin gauge and receiving unit of the tele
phone pay station. A preferred method of form
ing and welding the upper edges of the side walls
IT and 58 to the adjacent edges of the top IE
will be described hereinafter. The present in
vention is concerned primarily with means for
supporting and positioning certain devices of the
telephone coin collector on the inner surfaces of
the Wall portions i7 and 18 of the housing I5,
such devices in the drawings being shown in
a broken outline and are as follows: a coin chute
30, coin signaling devices 3! and 32, and a con
ductor terminal mounting block 33.
V In Fig. 1 cooperating combination supporting
15 and positioning brackets 35 and 38 are shown
?xed to the inner surfaces of the wall portions
if and i 3, respectively, of the housing i5. Each
of the brackets 35 and 35 comprises one integral
piece of metal, preferably sheet steel, produced
by suitable blanking; perforating and forming
operations in accordance with known practices
in the art of metal working. The bracket 35
(Figs. 1 and 2) includes an irregular shaped flat
base 3? having struck out or formed at its upper
25 end ears 38 provided with perforations 39 which
are subsequently threaded for the reception of
screws 45.. Intermediate the ears 38 and at the
left thereof (Fig. 2) the base 3? has a portion or
tongue 43 which is struck up to- provide an em
30
bossed or bridge portion {is having a raised cen
tral locking ridge
perforated at 416 and subse
‘ quently threaded for the reception of a. screw 4'].
At its lower end the base 31' is formed with an
, upwardly extending right angle portion I38 which
is bent upon itself to provide a portion 5i? lying
parallel to the base but raised therefrom, the por
tion 58 being perforated at its upper and lower
ends,‘ as indicated at 52, and subsequently thread
ed for the reception of screws 53. The upper end
of the portion 59 at its right side (Fig. 2) is pro
vided with a downwardly extending right angle
portion 5a having its lower edge lying in the plane
of the lower surface of the base 3?, the portion
54 being perforated at 5'5; The portions £8 and
5B of the bracket 35 are provided with an elon
gated perforation 58 for the purpose of providing
33 of the bracket 35 and the ear 64 of the bracket
36 are in horizontal alinement at opposite side
walls of the housing it. With the mentioned ears
of the brackets 35 and 35 in accurate desired rela
tion to each other as well as to the housing I5 it
follows that the coin chute 39 may be accurately
and readily assembled with and secured in the
housing by the screws iii) and 66 threaded into
the ears stand 6d of the brackets. Before mount
ing the coin chute
it is desirable for conveni 10
ence to assemble and mount the other devices
carried by the brackets 35 and 35. Thus the coin
signaling device 32 is secured to the bridge 67 of
the bracket 38 by means of the screw 7! , the coin
signaling device 35 to the bridge lid of the bracket 15
35 by the screw ‘iii, and the conductor terminal
mounting block 33 to the portion 53 of the bracket
35 by the screws
the terminal mounting block
being supported at its left side (Fig. 2) by means
of the ear 58 which has
upper edge surface in 20
the plane of the upper surface of the portion 58.
The perforation 57 of the portion
of the
racket 35 serves as a guide for conductors l3
terminating at the block 35.

55, Fig. 4 shows a portion of a blanked, formed
and perforated sheet of metal before it is folded 30
along dotted lines shown in Fig. 4, and indicated
at it, ‘it, '5'! and '58, to the form shown in Fig. 5
and before the adjacent edges are welded. The
side walls ii and 58 are thus bent at right angles
to the front wall it and in parallel relation to 35
each other. The top it is bent to conform to
upper edges l'S-JQ and itfi~8? of the side walls

The bracket 36 (Figs. 1 and 3) includes a base
63 having struck out or formed at its upper end

65 is subsequently threaded for the reception of a
screw 66. At its lower end the base 63 is formed
or struck up to provide an embossed or bridge por

threaded for the reception of a screw "i' l.
The cooperating brackets 35 and 36 are secured
in predetermined positions upon the inner sur
faces of the walls El and 53, respectively, of the
housing i5, preferably by spot or projection weld
“ ing, as indicated at‘lZ (Figs. 2 and 3).
It will
'76 be noted, referring to- Fig. 1, that the upper ear
of the ‘creased adjacent edge portions of the top
l9 and side walls l? and 58 when the blanked
sheet is folded is clearly shown. in Figs. 5 and 8,
the adjacent edge faces being slightly spaced
apart at their inner corners. The edge portions 60
‘iii-19 of the side walls ii and it and the ad
jacent edge portions of the top is are disposed at
right angles with the edge portions of the top [9
overlapping the side wall edge portions 'i'9—‘lQ
for substantially one-half their thickness, as 65
clearly shown'in Figs. 5 and 6, when the blanked
sheet is folded.
To secure the preformed adjacent edge por
tions of. the side walls i? and i8 and top 59 to

of additional Welding rod or‘ material (Figs. 7

manner shown in Fig. 8, a required ‘greater
radius of the corners at the rear portion of
the housing, with an adequate thickness of ma
terial thereat, is obtained as compared to the
front portion thereof and without the addition
of welding material. The greater radius at the
rear corners of the housing IS in the present

an inner radius on a ?ange of the mounting
plate which supports the housing. Also an im

mentioned devices permits a more economical
and accurate assembly thereof, within the hous
ing, since by combining the points of support of
the devices into a pair of cooperating brackets
it is possible to maintain closer relationship be
tween the supporting points, thus reducing the
number of adjusting or' positioning operations
required to meet the close limits for location of
the devices relative to each other as Well as upon
35 the walls of the housing. Also by combining the
plurality of points of support of the devices into
a simple pair of brackets the securing thereof to
the walls of the housing is greatly simpli?ed,
since each of the combination brackets can be
40 welded in position by a single stroke of a weld
ing machine. Furthermore manufacturing costs
are appreciably reduced by making a pair of
cooperating one-piece combination brackets over

being formed to extend forward of the plane of
