Improvements in Crimping Tongs.
I, GEORGE LEVERETT THOMPSON, Manufacturer, of 6629 Wentworth Avenue,
in the City of Chicago, County of Cook and State of Illinois, United States of
America, do hereby declare the nature of this invention to be as follows:-
A hair crimping tongs embodying my invention consists generally of two
pivotally connected parts or members, each comprising a shank and a handle
thereon; the handles of the two parts or members being adapted to be grasped by
the hand in operating the implement. Said pivotally connected members are
provided with tines or prongs which pass between each other in the use of the
implement, like those of other similar implements. The said parts or members are
not, however, connected by a pivot passing through the shanks, as heretofore
common, but they are united with each other by means of a pivot pin which is
inserted through the tines of one or both of the parts and enters the shank or tines
of the other part. In a form of the implement where one of the members is
provided with two tines and the other is provided with three tines, the member
having three tines may be made flat or with its three tines and shank in the same
plane, while the one having two tines is provided with arches at its inner ends and
is pivoted to the member having three tines by a pivot inserted through the tines of
the two-tined member and the shank of the three-tined member, the outer tines
of the three-tined member in such case being joined to the center tine and shank by
transverse bends which form shoulders adapted to enter or rest within the arches of
the two-tined member when the tines are brought together.
A main feature of the invention is embraced in a construction wherein the tines
of one or both of the parts or members of the implement are separated from each
other to a point beyond or at the rear of the pivotal joint which connects the parts
or members, and wherein one part intersects and passes between the tines of the
other part, and the parts are connected by a pivot pin passing through the tines of
one part and the shank of the other part where it intersects said tines or the tines
of both parts at their point of intersection.
The advantage of this construction is that a strong and reliable joint is formed
without the necessity of employing accurately fitted overlapping or interpenetrated
parts on the shanks to form the joints between the shanks as has heretofore been
the practice in constructing such instruments.

I, GEORGE LEVERETT THOMPSON, Manufacturer, of 6629 Wentworth Avenue,
in the City of Chicago, County of Cook and State of Illinois, 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:-
A hair crimping tongs embodying my invention consists generally of two pivotally
connected parts or members, each comprising a shank and a handle thereon; the
handles of the two parts or members being adapted. to be grasped by the hand in
operating the implement. Said pivotally connected members are provided with
tines or prongs which pass between each other in the, use of the implement, like
those of other similar implements. The said parts or members are not, however,
connected by a pivot passing through the shanks, as heretofore common, but they
are united with each other by means of a pivot pin which is inserted through the
tines of one or both of the parts and enters the shank or tines of the other part... In
a form of the implement where one of the members is provided with two times and
the other is provided with three tines, the member having three tines may be made
flat or with its three, tines and shank in the same plane, while the one having two
tines is provided with arches at its inner ends and is pivoted to the member having
three times by a pivot inserted through the tines of the two-tined member and the
shank of the three-tined member, the outer tines of the three-tined member in such
case being joined to the center tine and shank by transverse bends which form
shoulders adapted to enter or rest within the arches of the two-tined member when
the tines are brought together.
A main feature of the invention is embraced in a construction wherein the tines
of one or both of the parts or members of the implement are separated from each
other to a point beyond or at the rear of the pivotal joint which connects the parts
or members, and wherein one part intersects and passes between the tines of the
other part, and the parts are connected by a pivot pin passing through the tines of
one part and the shank of the other part where it intersects said tines or the tines
of both parts at their point of intersection.
The advantage of this construction is that a strong and reliable joint is formed
without the necessity of employing accurately fitted overlapping or interpenetrated
parts on the shanks to form the joints between the shanks as has heretofore been the
practice in constructing such instruments.
In the accompanying drawings:-
Figure 1 is a perspective view of a pair of crimping tongs embodying my
improvement.
Figure 2 is a plan view thereof.
Figure 3 is a perspective view of the tines or jaws of another form of crimping
tongs embodying a principal feature of my invention.
Figure 4 is a similar view showing a construction somewhat different from that
shown in Figure 3.
Figure 5 is a perspective view of the jaws of a five-tined implement of different
form from that; shown in Figures 1 and 2.
Figure 6 is a plan view of the implement shown in Figure 5.
As illustrated in Figures 1 and 2, the crimper is composed of two shanks, A
and B, each shaped or bent at one end to form hand loops, as indicated by a and b,
and having at its opposite end a fork provided with a plurality of tines, as indicated
at C and D.
The fork C of the shank A consists of three tines, c c c³, the outer tines c and c
being provided at their inner ends with shoulders, cc, formed by outward bends, o³ c³,

page_text: and reverse bends, ee, whereby the main parts of said outer tines c and e' are
brought parallel with the central tine e'and-at a distance therefrom a little greater
than their width....
4.1%
The fork D of the shank B is composed of two tines, d and d' parallel with each
other and provided at their inner ends with offset parts or arches, i d', within
which the shoulders cc of the shank A rest when the parts are in their closed
position and the sides of which near the shank are transversely pierced to receive a
pivot pin, E, which also passes through a transverse opening in the shank A near
its junction with the fork C, thus forming à pivot-joint...
Each of the shanks A and. B may be formed from a single blank, in a suitable
die, or by hand, or the tines e and ef of the shank A may be welded to the sides of
a blauk from which the shank and central tine e' is formed, while the tines d and d'
are welded to the shank B...
In the employment of either mode of construction the parts are finished
by any suitable method of smoothing and polishing metal and assembled as herein-
before described.
.........
In Figure 3 have shown a modification consisting of two shanks, E and F, of
which the shank E is provided with two tines, e e, and the shank F with a single
tine,, having an arch or offset, f, at its inner end or that adjacent to the shank;
the parts being connected in this instance by a pivot pin, G; passing through the
tines e e and the arched part of the tine f.
The implement in both forms above described has one straight member and
another member which is arched or offset to form the pivotal joint between the
members, but in Figures 4, 5, and 6, I have shown a construction wherein both
parts or members are arched or offset, the feature possessed in common by-all of
these forms being that the parts are made to cross or intersect each other adjacent
to the pivot in such manner that the pivot pin may be inserted therethrough and a
hinged joint thereby formed. As shown in Figure 4 the implement consists of two
shanks H and I of which the shank H is provided with a single tine h and' the
shank I with two tines i i. The tines of both members are provided with arches
or offsets adjacent to the shanks, said arches or offsets being so arranged that
the tines cross or intersect each other at a point convenient for the insertion of a
pivot pin J near the shanks.
lu Figure 5 is shown a form of implement consisting of a shank K provided with
three tines kkk and a shank L provided with two tines. These tines are provided
with arches k¹ k k and and the members are connected by a pivot M inserted
through the arched parts of the tines adjacent to the shank, in the same manner
as illustrated in connection with the three-tined form shown in Figure 4.
A main feature of the invention is embraced in a construction wherein the tines
of one or both parts of the implement are separated from each other to a point
beyond or at the rear of the pivotal joint connecting the parts or members, and
wherein one part intersects and passes between the tines of the other part, and the
parts are connected by a pivot pin passing through the tines of one part and the
shank of the other part where it intersects said tines, or the tines of both parts at
their point of intersection. The obvious advantage of this construction is that a
strong and reliable joint is formed without the necessity of employing accurately
fitted, overlapping or interpenetrating parts on the shank to form the joint, as has
heretofore been the practice. These advantages apply equally to the two forms
shown, to-wit, that in which the shank of one part is pivoted between the tines of
the other part, and that in which the tines of both parts are arranged to cross
each other and a pivot inserted through them; it being obvious that in both cases
a strong and durable joint is formed with little labor in addition to that required
for making the tines themselves. This simplicity and economy in manufacture is
well illustrated in the case of the article having three tines only, shown in Figure 3,
from which it will be seen that the tines e e are formed in the usual manner and
that no additional labor is necessary to form the hinge, except to properly bend
the shank F and insert the pivot pin through the parts. Similarly in the form

page_text: shown in Figure 4 the tines are made in the usual manner and the only
additional labor required for making the pivotal joint is to form the arches or
offsets in both parts and insert the pivot pin through the arches at their points of
intersection. A saving of labor is similarly effected in making an article with
five or more tines, it being obvious that the additional tines shown in Figure 1 are
secured outside of the pivotal joint which is formed between the two central tines
of one part and the shank of the other part, so that no special labor in forming the
joint is required. In the form shown in Figures 5 and 6 the tines are formed on
the two shanks, three on one and two on the other, in the same manner as would be
necessary for making the jaws in case the shanks of the members were pivotally
connected and the pivotal joint was formed by inserting the pivot through the
tines. In the construction shown in Figures 4, 5 and 6 the tines are bent in the
manner shown merely to bring the shanks and the working parts or outer ends of
the tines into proper relation with each other when the parts are closed, and the
bending of the tines to the particular form shown is not essential.
The form of five-tined implement shown in Figures 1 and 2 has the advantage
of being somewhat more easy to constructiand compact and neat in appearance than
the other one illustrated in Figures 5 and 6, and said form shown in Figures 1 and 2
being in itself new is herein claimed as part of my invention.
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. A crimping implement comprising a member having two or more tines
and a second member having one or more tines, said second member being inserted
between the tines of the first member and being pivotally connected therewith by a
pivot pin inserted through the tines of said first member.
2. A crimping implement comprising a member having two or more tines and a
second member having one or more tines, the shank of said second member being
inserted between the tines of the first member, and pivotally connected with the
same by a pivot pin inserted through said tines and said shank.
3. A crimping implement comprising a forked shank having two tines provided
with arches at their inner ends, and a second forked shank pivoted between the
tines of the first named shank, said second shank having three tines, of which the
outer ones are bent to form shoulders to rest within the said arches when the tines
are brought together, substantially as described.
