` Specification of Letters Patent. L

Application led September 27, 1910. Seri-a1 No. 584,099,

To all whom t may concern:

Be it known that we, HEINRICH LANGE and FRANZ DRUCKENMLLER, both subjects of the King of Prussia, and residents, respectively, of Kiel and Cologne-Nippes, lJrussia, Germany, have invented a new and "improved Insulator', of which the following is a full, clear, and exact description.

This invention relates to insulators for high tension and other electric conductors, and has reference more particularly to an insulator comprising a ,core and an insulating body having said core embedded therein, said core constituting a reinforcement for said body, means for securing the conductors to the body, and a liacket upon said body, consisting of insulating material, the resistance of which is not atlected by the action of light, air, salt water, smoke, etc.

'lheobject of the invention is to provide a simple and inexpensive insulator which. can be used in connection with high-tension conductors of over-head electric systems for wireless telegi'aphy and telephony, well as with the supporting tackle used with the masts of wireless telegraph systems, which possesses great strength, is of high resistive power, presents a large surface, which is of comparatively small circumference, and of o light weight, and which can be inexpensively produced.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set Jforth in the claims. n

Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure l is a lon itudinal section of an embodiment ot' our invention. l `ig. 2 is a similar view showing a modified form of the insulator. Fig. 3 is a similar view showing a further modiied form ot the insulator. Fig. 4 is a longitudinal section of another modified form ora the invention; and Fig. 5

is a transverse section of the form shown in :Fig: 4l. i

Before proceeding to a more detailed explanation oi our invention, it should be clearly understood that while the insulator is particularly useful inconnection with wireless apparatus, it can also be advantageously employed itor other purposes, in

which electric insulators of considerable strength, light weight, and high resistive power are desired.

Certain of the details of construction, shown for example herewith, form no part of the invention, and can be varied in accordance with individual preference and' Patented July 2,1912.

special conditions, without departing ltrom the underlying spirit of the invention;

Referring more particularly to the drawA ings, the form ot the invention shown in `Fig. 1 has a core 10 fashioned either 'from conducting or non-conducting material, such as bronze, steel, or the like, or wood fibers, gut, etc. The core is of elongated forni and has enlargements 11 at the ends.l 'The body oit the insulator, l2, has the core embedded therein, and is of elongated form with enlarged ends 13, which receive the corresponding parts 11 of the core. Sock` ets 11i receive the enlarged ends ofthe. body and have inwardly disposed ianges 15 engaging at the enlargements 18. The sockets have associated therewith, integrally or otherwise, eyes 16 to which the conductors or other members carried by the insulator are secured. The jacket 17 encompasses the body of the insulator between the ends thereof, and is of suitable length to extend nearly to the extremities of the insulator. lt is fashioned from any suitable material, the resistance of which is not affected by light, air sea water, etc., consisting for example, oi' amber, oi' glazed porcelain. The non-conducting body 12 may be Jfashioned from any material of high resistivity, for example, from hard rubber or the like. In the form of the device shown in Fig. 2, we employ two cores 18, spaced apart, and having serrated, enlarged ends 19. The body in which the cores are embedded, is similar to the body 12. The remaining elements of this form, consisting respectively of the sockets 19 and the jacket 21, correspond to the like elements in the previously described. modification.

The above types of the insulator are in claim as new, and fdesire to s ecure by lpiasa l form and has near the ends openings 23. The body 24 of the insulator is fashioned from material of high resistivity, encompasses the core and also lines the p'enings. The jacket 25' is similar tov the jacket 21 or the jacket 17. In the openings 22 are bearingmembers 26, which support thev conduct-ors or cables with which the insulator is used.

In Figs. 4 and 5 We have illustrated a further moditied forni of the insulator simi- -lar to the form mentioned, but having the core 27 of cross-shaped section intermediate the ends, for purposes of lightness. The body 28 encompasses the core, and the remainin elements of the insulator are similar to tose shown in Fi 3.

Having thus describe our invention We Iletters Patent: j A

1. A11 insulator, ycomprising a j bar-like L core, an insulating body 'wholly encompassin the core, a single elongated tube of ins atin material and surrounding the body said tu e terminating short of t e ends `of the body, and conductor securing means at the ends of the insulator.

2. An insulator, comprising a bar-like core having transverse openings in its ends, an insulating body wholly encompassing the core and linmg the opening thereof, and an insulating jacket surrounding the body.

3. An vinsulator comprising a bar-like core, cross-shaped intermediate of its ends and having a transverse opening in each end, an insulating body Wholly encompassing the core and lining the openings theregf, and an'insulating jacket' surrounding the 1151, testimony that we claim the foregoing as our invention,we have si ed our names, in presence of two subscribln `Witnesses.
