HAIR. WAVING CLAlWP
Bernard A. Sterling, Chicago, Ill.
Application April 15, 1935, Serial No.'16,'314
6 Claims.
(C‘l. 132-36.1)
This invention relates to a hair-waving or pro-
tongues» 9 offset to lie closely together and eX
tector clamp for application to the hair during
the process of waving the same, and may be
characterized as an improvement upon the hair
5 waving clamp disclosed and claimed in my co-
pending application, Serial No. 748,992, filed October 19, 1934.
One of the features of the present invention
is the provision of improved resilient facing mem-
flanges of the jaw 6. The tongues 8 and 9 are
pivotally joined'by the pivot '1, whichV may be in
the form of a rivet or of other suitable or pre- 5‘
ferred form. The pivoted end of the jaw 6 has a
tab il which is widened and turned up and
notched at I2 to receive and support rotatably
the adjacent end of the curler spool, indicated
10 bers for the jaws of the clamp, and particularly
in its entirety at I3.
an improved spring arrangement for the meeting
surfaces of these members whereby to improve
the action and increase the life of these` surfaces,
particularly along the location where the bunched
15 strand of hair is gripped.
Another feature is the provision of an improved
mounting for these resilient facing members,
which mounting will permit convenient removal
and reversal of the facing members on the jaws
The back of the jaw 5 terminates short of the
free end of the jaw, leaving the projecting tongues
I4. The upper tongue I4 is elongated and folded
back and turned up at I5 to form one side o-f the
journal for the adjacent end of the curler I3. »lo
The back of the jaw 6 likewise terminates short
of the free end of the jaw, and the adjacent end
of the top flange of the channel section of this
jaw is widened, turned up at I6, and notched at
20 of the clamp.

Referring to the drawing, the clamp selected
for illustration comprises a pair of elongated jaws
5 and 6 pivotally connected together at one/'end

45 device for closing the jaws and locking the same
in closed position. This device is similar tothe

Another feature resides in an improved mounting and stop arrangement for the spring paw] for
holding the hair-waving spool against unwinding.

same in closed position comprises a lever 50
pivoted for free swinging movement at one end
A heat insulating strip 25, of felt »or other suit
able material, is secured to the bottom of each
10 of the facing members 2li preferably by means
of parallel lines of stitching indicated at 25.
Of course these strips 25 may be secured to the
members 25 in any other suitable or preferred
manner. The strips 25 are substantially coex
15 tensive with the facing members 20, and their
opposite ends project endwise beyond the mem
bers 20 to underlie substantially the entire length
of each jaw 5 and 5. The relatively flat form of
the channel-shaped jaws 5, together with the
20 rounding of the upper and lower edges of the
backs of these jaws, permit the facing members
to be applied and removed sidewise and then
turned to the position shown, although the form
and yieldability> of the members 2B will permit
25 these members to be applied from the bottom and
directly to the desired position and similarly re
moved.
Disposed within the channel sections of the
jaws 5 and 5 are springs 28 having intermediate
30 portions 29 lying along the open inner sides of
the jaws.
The inturned ends 3l! of the springs
29 terminate in longitudinal extensions which are
adapted to be sprung between and into interlock
ing engagement with prongs 32 pressed in from
35 the back walls of the jaws 5 and '5. The spring
ing of the ends of the springs 28 between and into
engagement with the prongs 32 secures the
springs 28 removably in position within the jaws
and bows the intermediate portions 29 outwardly
and places the same under tension. These bowed
intermediate portions 29 of the springs 28 press
the inner side flanges of the facing members 25
inwardly and provide an effective gripping action
upon the bunched strand of hair placed between
the jaws, as indicated at 34. The springs 28
maintain an effective gripping action of the
members 20 upon the hair at all times and in
crease the life of the members 20, particularly
along the locations where the hair is gripped.
50 And the life of these members 29 is further in
creased by the reversibility of the same upon the
jaws 5 and 6.' The springs 23 preferably bow
the inner sides of the facing members 20 to con
Vex form along the locations where the hair 34
55 is gripped, as shown at 35 in Figure 2.
The particular curler I3, selected for illustra
tion, is ofthe type more fully disclosed in my
prior patent, No. 1,862,721, patented June 14, 1932.
Suñice it to say that this curler comprises the
60 metal spool or reel 35 of circular section, di
minishing in diameter from its opposite ends
toward the center, and a saddle-like retainer 31
pivoted to one end of the spool at 38. A iinger
piece 39 is provided at one end of the spool for
65 turning the same, and the ‘opposite end of the
spool has teeth '46 which cooperate with a spring
pawl 42 to prevent unwinding of the spool.
The spring pawl 42 comprises a spring strip
turned in beneath the bottom of the jaw 6 and
70 secured thereto as by means of a rivet 43. A
prong 44, struck in from the spring strip, en
gages the teeth 40 and holds the spool against
unwinding. The upper end of the spring strip is
pawl.
The device for closing the jaws and locking the
at 5l between the tongues I4 of the jaw 5.
The
lever 5D comprises a pair of superposed arched
pieces between the pivoted ends of which a Washer
52 is provided. A latch 53 is pivoted at 56 be
tween the free ends of the arched pieces consti
tuting the lever 5D, and this latch 53 preferably
has a shoulder 54 which, by engagement with an
integral stop 55 turned down from the edge of
the top piece of the lever 50, limits swinging
movement of the latch in a cl`o`ckwise direction
with respect to the lever 50 as viewed in Figure 2.
The pieces constituting the lever 50 have lips 5U’
turned in, or the pieces are otherwise formed to
bear against the latch member 53 to prevent free
turning of the latch with respect to the lever.
As a result, the latch 53 and lever 5U swing sub
stantially as a unit about the pivotalll connection
at 5l with the jaw 5, and until the latch en
gages the other jaw, whereupon the latch and
lever swing about their respective pivots, as will
appear. The latch 53 has a relatively short pro
jecting ñnger 51 provided with a rounded cam
edge 58 which has a depression 59. The latch
53 also has a finger-piece '60 turned at substan
.
tially right angles to the pivoted part of the latch
and preferably elongated to give the operator
a considerable mechanical advantage in closing
and locking the device.
35,
Further, to facilitate ease of operation of the
device, the part on the jaw G for cooperation with
the jaw closing and locking latch 53 is in the form
of a roller 62. This roller 62 is mounted between
integral tongues 53 projecting endwise from the
top and bottom flanges of the channel section of
the jaw 6 for free turning movement upon a
pin 64 ñxed in the tongue B3 as by heading one
end and riveting over the opposite end of the
pin.
-
With a bunch of hair between the jaws 5 and
6 as shown in Figure 2, the device is closed by ap
plying the ñnger to the finger-piece 69 and press
ing the same in the direction indicated by the
arrow in Figure 2. This swings the latch 53 and
lever 50 as a unit, or at least substantially as a
unit, about the pivot 5I until the finger 51 takes
over the roller 62. Thereupon, as the ñnger
piece 60 is pressed further in the same direction,
the lever 50 continues its swinging movement in 55
a counter-clockwise direction about the pivot 5l
and, at the same time, the latch 53 swings in a
counter-clockwise direction about the pivot 58.
The resulting action gives the operator great
mechanical advantage and forces the jaws 5 and
5 positively to closed position with great force.
The roller action, due to the engagement of the
roller 52 with the latch 53, further facilitates
the closing and locking action, and as the pin 64
moves into or past dead center a-a (Figure 3), 65
the jaws 5 and 6 are locked positively in closed
position.
