UNITED STATES PATENT OFFICE
CHARLES K. KING, OF MANSFIELD, OHIO.
SPECIFICATION forming part of Letters Patent No. 667,882, dated February 12, 1901.
Application filed December 10, 1900, Serial No. 39,354. (No Model.)
To all whom it may concern:
it known that I, CHARLES K. KING, a citizen of the United States,
residing at Mansfield, in the county of Richland and State of Ohio, have
invented a new and useful Feeder Wire Insulator, of which the following
is a specification.
invention relates to feeder-wire insulators.
object of the invention is to provide a simple and efficient
construction of insulator for feeder or other electric wires.
invention consists, substantially, in the construction, combination,
location, and arrangement, all as will be more fully hereinafter set
forth, as shown in the accompanying drawings, and finally pointed out in
the appended claims.
to the accompanying drawings and to the various views and reference
signs appearing thereon, Figure 1 is a view, partly in section, of a
feeder or other electric wire insulator constructed in accordance with
the principles of my invention and showing the parts in assembled
relation. Fig 2 is an end
view showing the insulator supporting pin and locking washer in locked
relation. Fig. 3 is a
similar view showing the pin and locking washer in unlocked relation.
Fig. 4 is a broken detail view in perspective of the pin and
locking washer. Fig. 5 is a
central longitudinal section through the insulator.
same part is designated by the same reference sign wherever it occurs.
sign A designates the pin, B the insulator, and C the locking washer.
pin A is preferably fluted, barbed, and pointed at one end thereof, as
clearly shown in Fig. 1, thereby enabling the same to be easily driven
in place and to secure a firm anchorage in the side wall, roof, or other
convenient support in a mine or other locality where the use thereof may
be desired. The other end
of pin A is suitably formed or shaped to facilitate the placing of the
insulator B thereon. In the
particular form shown, to which, however, my invention is not limited,
said end is made cylindrical and at the extremity thereof is provided
with one or more lugs D.
The insulator B may be of any suitable insulating
material, highly vitrified porcelain being preferable, by reason of its
strength and toughness and of its being absolutely impervious to
moisture. This insulator
should be of sufficient size to prevent surface leakage of current from
the wire to be supported thereon to the supporting pin A
If desired, the insulator may be provided with a peripheral
groove E to receive and securely hold in place and support the wire to
be supported and insulated. At
one end of the insulator is provided a countersunk recess or seat,
(indicated at F), the function of which is to receive any moisture or
dripping running down pin A, thereby preventing such moisture from
reaching or accumulating upon the wire supported by the insulator.
The insulator is provided with a central longitudinal bore or
opening G therethrough, adapted to receive the end of the pin A.
One or more longitudinal passages H may also he provided with an
opening into the central bore G to permit the passage of the lug or lugs
D on the end of pin A. These passages and also the central bore G have a
passage way for any dripping or moisture which may collect in the seat
or recess F of the insulator, whereby such moisture or drippings may be
carried off and away from the wire supported by the insulator.
The locking-washer C is provided with a central opening therethrough, so as to enable the same to be strung upon the pin A. Said washer is also provided with one or more openings or passages J therethrough to permit of the passage therethrough of the lug or lugs D on the end of pin A. Said washer is also provided with one or more seats or depressions K in one of the faces thereof adapted to receive the lug or lugs D of pin A and form a lock therefor. The central bore G and the passage or passages H through the insulator, as well as the central opening through the washer C and the passages J, are
somewhat larger than the pin A and lug or lugs D thereon, so as to permit
said insulator and washer to be readily strung upon or removed from said
pin. The locking washer is
preferably flattened on one of the faces thereof to form a bearing
against the end surface of the insulator, the notches or seats K to
receive the lug or lugs D being formed in the opposite
face of such washer. If desired, and as shown at L, the end of the
insulator against which the locking-washer bears may be somewhat
countersunk to receive the washer therein, as clearly shown in Fig. 1.
In operation the pin A is firmly driven into place in the ceiling or side wall of a mine or other place where it is desired to use the support, the locking-washer and insulator having previously been
therefrom. If desired, a
hole may have been previously bored to form an entranceway far the point
of the pin; but this feature may be omitted.
The insulator B is then replaced upon the shank of the pin, said
pin passing through the central bore or opening G in the insulator and
the lug or lugs D passing through the passages H.
In a similar manner the washer is then strung open the end of the
shank of pin
the foregoing description it will be seen that I provide an exceedingly
simple and efficient construction of insulated support for feeder or
other electric wires, which can be readily and easily detached and
now set forth the object and nature of my invention and a construction
embodying the principles thereof, what I claim as new and useful and of
my own invention, and desire to secure by Letters Patent, is--
1. In a feeder-wire insulator, a pin or support having one or more lugs
at the end thereof, an insulator having a central bore to receive said
pin there through, and one or more passages opening into said bore to
permit the passage of said lug or lugs there through, and a
washer for retaining said insulator upon said pin, as and for the
purpose set forth.
In a feeder wire insulator, the combination of a pin, an insulator and a
locking washer, said pin adapted to receive the insulator thereon and
provided with one or more lugs, said locking washer adapted to be
received upon said pin and provided with one or more openings to permit
of the passage therethrough of the lug or lugs on the end of said pin
and having seats to receive said lug or lugs, as and for the purpose set
In a feeder wire insulator, the combination of a pin, an
insulator and a locking washer, said insulator and washer adapted to be
received upon said pin, said washer provided with a flat face on one
side to form a bearing for said insulator, said pin having one or more
lugs and seats formed in the opposite face of said washer to receive
said lug or lugs to lock said washer in place, as and for the purpose
In a feeder wire insulator, the combination with a pin, of an insulator
adapted to be detachably mounted upon said pin, said insulator provided
with a deep countersink or recess in the end thereof to receive moisture
or drippings from said pin, and having one or more passages there
through to conduct such moisture or drippings away from the wire to be
supported thereby, as and for the purpose set forth.
The combination with a pin, an insulator and a locking washer, a1l
combined and arranged as and for the purpose set forth.
witness whereof I have hereunto set my hand, this 6th day of December,
1900, in the presence of the subscribing witnesses.
CHARLES K. KING.
