CHARLES ALBERT KOCH, OF AUSTIN, TEXAS.
HAT-PIN-POINT PROTECTOR.1,262,058.
Specification of Letters Patent.
Patented Apr. 9,1918.
Application fMed February 2,1916. Serial No. 75,864.
To ,awhom it may concern:
Be it known that I, CHARLES A. Kocn, a
citizen of the United States, residing at Aus-
tin, in the county of Travis and State of
5 Texas, have invented a new and useful Hat-
Pin-Point Protector, of which the following
is a specification.
The device forming the subject matter of
this application is adapted to be used for
10 protecting the point of a hat pin, and the
invention aims to improve the operative
connection between the complemental mem-
bers which shield and grip the point of the
pin.
15 It is within the province of the disclosure
to improve generally and to enhance the
utility of devices of that type to which the
present invention appertains.
With the above and other objects in view
20 which will appear as the description pro-
ceeds, the invention resides in the combina-
tion and arrangement of parts and in the
details of construction hereinafter described
and claimed, it being understood that
25 changes in the precise embodiment of the in-
vention herein disclosed can be made within
the scope of what is claimed, without de-
parting from the spirit of the invention.
In the accompanying drawings:-
30 Figure 1 shows in longitudinal section, a
hat pin point protector constructed in ac-
cordance with the present invention, parts
appearing in elevation;
Fig. 2 is a cross section on the line 2-2
35 of Fig. 1;
Fig. 3 is a cross section on the line 3-3
of Fig. 1; and
Fig. 4 is a side elevation showing the pro-
tector forming the subject matter of this ap-
40 plication, mounted on the end of a hat pin.
The structure forming the subject matter
of this application preferably is made out
of steel or other hard material and includes
a body B provided at one end with a flared
45 guiding mouth 1. In the body B to the rear
of the guiding mouth 1 there is fashioned a
flared bore 25, the bore 25 and the mouth 1
tapering in opposite directions, and the
small ends of the mouth 1 and the bore 25
50 being in communication, as indicated at 18.
In the body B to the rear of the flared bore
25, a cylindrical bore 13 is formed, the same
being internally screw threaded as shown at
10. The cylindrical bore 13 forms in the
55 body B, at the rear end thereof, a relativelythin wall; the extremity 'of which is turned
inwardly toward the axis of the body B:'to
form a retaining flange 26.
The invention comprises a button includ-
ing a terminal head D and a reduced neck a. 60
The neck a extends within the cylindrical
bore 13 and the flared bore 25 and is beveled
as shown at 38 to cooperate with the wall of
the flared bore 25. The forward or inner
end of the neck a is supplied with longitudi- 65
nal slots 2, 3 and 4 defining compressible
pin-gripping arms 5, 6 and 7. In the head
D and the neck a is formed an axial pin
seat 8 which is extended as shown at 28,
onto the inner edges of the arms 5, 6 and 7. 70
Intermediate its ends, the neck a of the but-
ton is provided with a screw threaded por-
tion 9, which is of greater diameter than
the neck a itself, thereby to form a shoulder
27. The screw threaded portion 9 of the 75
neck a cooperates with the threads 10 in the
cylindrical bore 13 and the shoulder 27 is
adapted to cooperate with the retaining
flange 26.
In practical operation the button A-D is 80
rotated readily by means of the head D,
since this head is of greater diameter than
the body B, and since the head D and the
body B are milled as shown at 39, so that
one of the parts may be held while the other 85
is being rotated. The button may be backed
partially out of the body B, when the button
is rotated, and the outer beveled edges 38 of
the arms 5, 6 and 7, moving backwardly
away from the wall of the flared bore 25, 90
will permit a separation of the arms 5, 6 and
7 with respect to each other. In this con-
nection it is to be observed that the shoulder
27 is adapted to cooperate with the flange
26, to prevent a complete separation be- 95
tween the body B and the button. The nu-
meral C indicates one end of a hat pin,
which may be guided by the mouth 1 into
the pin seat 8. Then. if the button be ro-
tated, the cooperating threaded portions 10 100
and 9 will advance the button, causing the
beveled parts 38 of the arms 5, 6 and 7, to
cooperate with the flared bore 25, the arms
gripping the pin C in a manner which will
be obvious to those skilled in the art. 105
The device forming the subject matter
of this application provides a means where-
by the point of a hat pin may be shielded,
the protecting structure being held securely
on the end of the hat pin, and a means be- 110
