Neither the register nor the signal nor the
two combined are shown in the drawings
since these structures form no part of the
present invention, in themselves, but any
5 approved type of register or signal or both
combined may be used in connection with the
present invention.
Since the contact device of the present in-
vention is mounted upon the seat portion of
10 the chair and since in practice such chairs are
arranged for the complete rotation of the seat
portion, I have made provision for such rota-
tion without in any manner breaking the con-
tinuity of the electric circuit so that the reg-
15 ister or signal may be placed at any distant
point and the contact device may be located
on the rotary portion of the chair. This
structure is shown in Figs. 1 and 2. Upon
the pedestal 2 at the top thereof there is se-
20 curely fixed a collar 19 clamped thereto by
bolts 20. Rising from the upper edge of the
collar 19 are brackets 21 carrying two up-
right spaced rollers 22-23 and an interme-
diate horizontal roller 24. In the drawing
25 there are shown four of these brackets but II
may use three or five or any other number de-
sired. The brackets carry between their
rollers an annular plate 25 of insulating ma-
terial engaged on the top and bottom sur-
30 faces by the rollers 22 and 23 and around the
inner edge of the roller 24. The annular
plate or disk 25 is thus securely supported
and is at the same time free to rotate about
the several rollers which constituteanti-fric-
35 tion or roller bearings therefor.
In order that the plate or disk25 may be
rotated with the chair-seat, there is attached
to the bottom of the latter a rod26 project-
ing downward through a perforation 27
40 formed in a lug 28 on one side of the disk 25.
The chair-seat may be elevated or depressed
with relation to the disk 25 which has a fixed
position with relation to the pedestal 2, and
at the same time the disk 25, which is freely
45 rotatable about the pedestal 2, will partici-
pate in any rotary motion imparted to the
chair seat, being constrained to do so by the
rod 26.
On the under side of the annular disk 25
5o are mounted a number of concentric metallic
rings 29, and to two of these rings the con-
ductors 1S are attached, being passed
through perforations 30 in the annulus and
making good electrical contact with the
55 rings by being soldered or otherwise secured
thereto. For the register-operating device
forming the subject of the present invention
but two of the rings are necessary, but since
the barber's chair may be provided with
60 other register-operating devices for other
purposes than that of indicating the number
of shaves the disk 257may have as many
pairs of rings 29 as may be necessary.
The collar 19 is provided with a laterally
65 extending bracket or rod 317on which arefixed one or more pairs of brushes 32 in- con-
stant engagement with the rings 29. In the
drawings but one pair of brushes 32 is shown
but it will be understood that as many pairs
will be provided as may be found necessary. 70
From the brushes 32, conductors 33 lead to
any distant point where the register, signal,
or combined register and signal may be lo-
cated.
It will be seen that the disk 25 with its con- 75
ducting rings and the fixed brushes 32 con-
stitutes a means whereby the continuity of
the circuit between the rotary and fixed por-
tions of the chair is maintained at all times.
It will be understood, of course, that the con- 80
ductors 18 will be sufficiently - long and
flexible to permit the chair seat to be ele-
vated or depressed through its entire range
of movement without bringing any strain
on these conductors 18. 85
I claim:
1. In a barber's chair of the reclining type,
movable arm -and foot-rest parts, a circuit
terminal attached to a movable portion of
the arm and another circuit terminal at- 90
tacked to a movable portion of the foot-rest
and arranged in the path of the first-named
terminal.
2. In a barber's chair of the reclining type,
movable arm and foot-rest parts, a circuit 95
terminal attached to a movable portion of
the arm and another circuit terminal at-
tached to a movable portion of the foot-rest .
and having a conducting member in the path
of the first-named terminal during its move- 100
meant in one direction and an insulating
member in the path of the said first-named
terminal during its movement in the other
direction.
3. In a barber's chair of the reclining type, 105
movable arm and foot-rest parts, a casing at-
tached to the foot-rest part and containing
an electric circuit terminal composed of a
conducting member and an insulating mem-
ber, and a circuit terminal carried by the 110
movable arm and having a brush arranged
to engage the conducting member of the other
circuit terminal when the brush is moved in
one direction and to engage the insulating
member of the other circuit terminal when 115
the brush is moved in the reverse direction.
4. A barber's chair having a seat rotatable
in and movable vertically with reference to
its pedestal or support, circuit terminals car-
ried by the seat, rotatable conducting rings 120
carried by the pedestal and connected to the
circuit terminals on the seat, connections be-
tween the seat and conducting rings con-
straining the latter to rotate with the seat
irrespective of its vertical movement and 125
brushes carried by the pedestal in engage-
ment with the conducting rings and included
in an external circuit.5. A barber's chair having a seat rotatable
in and movable vertically with reference to 1302
