FRED M. LOOKE, OF VICTOR, NEW YORK.
INSULATOR.
SPECIFICATION forming part of Letters Patent No. 767,948, dated August 16, 1904.
Application filed August 30, 1902.
To (tZl whom, it may concern.-
Be it known that I, FRED M. LOCKE, of Victor, in the county of Ontario, in the State of N ewYork, have invented new and useful Improvements in Insulators, of which the following, taken in connection with the accompanysulator that it may be supported upon a pin passing through the center thereof and be supported between the cross-arms and out of contact with them and in the several other new and novel features of construction which are hereinafter described, and specifically set forth in the claims hereunto annexed.
It-is constructed as follows, reference being had to the accompanying drawings, in which Figure 1 shows a view of the insulator supported upon a pin and carrying a wire, the pin being supported between the cross arms. Fig. 2 is a vertical section of the insulator shown in Fig. 1 detached. Fig. 3 is a modified view thereof, similar in all respects except that it is not provided with an eavestrough at the top.
a is the insulator, constructed of glass,porcelain, earthenware, or similar material, comprising a body portion at, having a wiregroove 5. The upper end is provided with a helmet or skirt 0, terminating in an eavestrough 0, provided with spouts (Z. Adjacent the lower portion is a skirt or petticoat e, as shown.
e is a central opemng for the reception of Serial Nb. 121,604. (No model.)
the insulator-pin f, upon which the insulator is mounted. This opening 0 is preferably increased in size as it approaches either end, as shown at g, and affords means for wedging the insulator tight to the pin, so as to prevent vertical displacement, and also provides means for allowing the insulator to move slightly at the top or bottom in a lateral direction, so as to impart a yielding motion to the a variety of ways, either by wedging it in or cement, or compositions of various kinds may be poured in, so as to fill up the space around the insulator at the proper place, or a wood pin may be used.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
An insulator comprising a body of cylindrical form'having a uniform exterior having its upper extremity formed with a downwardly-extending skirt, a second skirt located adjacent the lower end of the body and having its lower edge located above the bottom edge of the body, said body having a groove formed at its juncture with said lower skirt, the bore of said body having its extremities flared to enable wedging engagement with the support.
In witness whereof I have hereunto set my hand this 25th day of August, 1902.
