SPECIFICATION forming part of Letters Patent No. 745,284, dated November 24, 1903.
Application led May 5, 1902. Serial No. 105,963. (No model.)
T0 all whom it may concern:
Be it known that l, FRED M. LOCKE, of Victor, in the county of Ontario, in the State of New York, have invented new and useful lmprovements in Insulators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to improvements in insulators constructed of glass, earthenware, porcelain, or similar materials of two or more shells and which are secured together, so as to form an air-chamber inclosing the upper ends of the inner shell or shells.
My object is to construct such an insulator made up of any number of shells in which an air-chamber is formedY between the adjacent faces of the inner' shells at the point of alinenient between the conductor and pin; and to that end my invention consists in the several new and novel features of construction hereina'fter described, and specically set forth in theclaimshereuntoannexed. Itisconstructed as follows, reference being had to the accompanying drawing, in which I show a section through the center of the insulator made up in three parts.
a, h, and c are the shells or parts which compose the insulator, the outer shells a and b being constructed with an interior recess d and e. The outer shells d and?) are also provided with annular shouldersfand g, and the member or shell c has a similar shoulder 7L, so that when all of the parts or shells are nested together these shoulders will comein contact with each other, or, in other words, the shells when placed in inverted position will contact only at these annular shoulders, thereby leaving air-chambers Z and m between the shells aand l) andl) and c, respectively. After these shells are nested together, as shown, they may then be connected or otherwise secured together at the shoulders. y This may be doney in a variety of ways, either by fusing them together with glaze at this point or any other way which may be found practical.
The separate shells or parts which compose the insulator may also be molded and glazed by dipping or otherwise separately and then iired separately and then secured together in any ordinary manner, or the parts may be separately molded, dipped, and fired, then nested together and turned bottom side npward, and fired sufficiently to allow glaze to l melt from the side of the shells and How down and make a joint, as shown in the dark lines at o. No particular claim, however, is made for the method by which these insulators are constructed, but only to the construction which provides for an airspace between the shells above the point of contact and in alinement between the conductor and the pin. It is preferable that this air-chamber be hermetically sealed, although that is not absolutely necessary, for it will be observed that when the insulator is mounted with the petticoats extending downward very little, it' any, moisture would be liable to creep up through any crevices which there might be and get into the air-space. It will also be observed that by the construction set forth an insulator constructed as described in which the parts are all molded separately and glazed and then fired in the kiln and then secured together, the number of glazed walls and also the space between the cable and support is increased.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
l. An insulator constructed of two or more shells consisting of two or more glazed shells glazed at their shoulders and having an airspace between them.
2. An insulator composed of two or more shells connected together at the annular shouldersf and 71 and having an air-space practically inclosing the inner shells.
3. An insulator constructed of two or more shells glazed and secured together by glaze at the shoulders fand 71v and having an airspace between them.
4. An insulator constructed of two or more shells of porcelain 'or similar material connected together at the shoulders and having an air-space between the shells and in alinement with the conductor and pin.
5. A high-potential electric insulator composed of a plurality of cup-shaped pieces or bells connected together1 at the annular shoulder f, having an air-space practically inclosing the inner bell.
In witness whereof I have hereunto set my hand this lst day of May, 1902.
