UNITED STATES PATENT OFFICE.
CHARLES SMITHSON AND JOI-IN W. OSBORNE, OF WINCI-IESTER, ILLINOIS; SAID OSBORNE ASSIGNOR TO SAID SMITI-ISON.
INSULATOR.
To all whom it may concern:
Be it known that we, CHARLES SMrrnsoN and JOHN WV. OsBoRNn, citizens of the United States, residing at W'inCheSter, in the county of Scott and State of Illinois, have invented certain new and useful Improvements in Insulators; and we do declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to an insulator for telegraph or telephone wires and has for its object to provide a form of insulator by means of which the tie wires may be dispensed with and which will withstand storms without breaking.
Vith this and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.
In the accompanying drawings: Figure 1 is a side elevation of an insulator embodying our improvements; F ig. 2 is a central longitudinal section of the upper portion thereof with the clamping lugs turned up; Fig. 3 is a vertical transverse section; and, Fig. 4 an inverted plan view showing the interior of the hood.
Referring to the drawings for a more particular description of the invention the insulator comprises a hood 1 of frusto-pyramidal form having the outwardly inclined sides and ends 2 and 3 respectively.
4 indicates the insulator support which comprises a flat body which is adapted to t within the hood and a central cylindrical stem 5 having an outer eXteriorly threaded portion 6 adapted to screw into a suitable support. The body 4 of the support is insulated from the hood by interposed strips of mica 7 or other suitable insulating material therebetween while the support is held within or secured to the hood by means of the clamping lugs 8 which are formed by portions of the side and end walls thereof and are bent upwardly against the bottom face of said body. The hood is provided with a plurality of vertical pins 9 which are notched out to receive the wire.
Specification of Letters Patent.
Application filed September 23, 1909.
Patented July 19, 1910.
serial No. 519,177.
From the foregoing it will be seen that our insulator may be quickly adjusted in position and when so adjusted will weather severe storms without breaking.
From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacricing any of the advantages of this invention as dened in the appended claims.
`We claim as our invention.
1. An insulator comprising a hood, a support comprising a flat body adapted to fit within the hood and acentral eXteriorly threaded stem, strips of insulating material interposed between the head and the body of the support and means for clamping the body of the support in position.
2. An insulator of the class described comprising a hood, a support comprising a flat body adapted to fit within the hood and a central eXteriorly threaded stem, insulating material interposed between the body of the support and the hood and clamping lugs formed at opposite ends and sides of the hood and adapted to be bent inwardly against the body of the support.
8. An insulator of the class described comprising a hood having outwardly inclined sides and ends, a support consisting of a flat body adapted to fit within the hood, and a central eXteriorly threaded stem, insulating material interposed between the body of the support and the hood and lugs formed on opposite sides and ends of the hood and adapted to be bent inwardly against the body of the support.
In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
CHARLES SMITI-ISON. JOHN W. OSBORNE.
