INSULATOR FOR 'TENsmNeeu sr To all whom it may concern- Be it known that I, ALEXANDER E. BROWN,

- of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Insulator for Tension-Guys; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which make a part of this application and wherein the same parts are in each case denoted by the same referential letters.

The invention relates, primarily, to the means employed generally for the purpose of sustaining and holding in place electricallycharged bodies or conductors; but more specifically and as illustrated and, described in the present instance tosuch means when used in connection with the guys of electrical masts-of the kind, for instance, used in space or Wireless telegraphy and which is shown and is the subject-matter of the applications by me for a United States patent, filed August 3, 1906, hearing Serial Nos. 329,097 and 329,099. In uses. of this sort, by, reason of the extreme length and consequent. weight of the supporting-guys employed and the heavy wind-pressure to which they are exposed, the strain upon the intermediate insulating members of such guys is so great that .ordinary insulators such as used, for instance, in connection with and be wholly unfit for the purpose.

It is the purpose and object of my present invention to provide an insulator that will withstand these high strains in whatsoever situations and to whatsoeverconditions they are subjected. t

I will now proceed to explain the insulator in question by reference to the several drawings,wherein pairs or sets of two, in series at Figure 1 represents a side view of an insulator within lts'protecting-hood; Fig. 2, a top VlGW'fOf the same hood referred to is withdrawn; v Fig. 3, a sectional view through the' lines as a: of 'Fig. 2;

and Fig. 4, the insulator arranged ina guy, in the point of connection of the guy with the "mast.

Ais a hollow spool-shaped cylinder, of porcelain or other non-conductive material, Within which in the .first instance is loosely fitted the axial steel pin C, terminating at each end in the shoulders 3, provided with the cotter- Specification of Letters Patent.

These bars are held in their-relative positions by the pinC at their one end and :a similar central aperture at 0 whereby a rope-socket s is connected 1 G represents the guy inmartial" disclosure.

thepin at right M is a portion-of a mast in conne'ctiiin with which the form of insulator is shown as used inF1g.4. i v I find it extremely desirable to accompany of the packing i on said compressible side to about forty-five degrees from a plane that passes 1 the tension or pull the invention proper with a suitable form of hood or covering to protect the same against impairment by the elements, and in consequence combine with the insulator as one form of the invention such a hood or covering as indicated by D and D, D being the hood adopted at the mast-terminal of the guys G, and D those above the insulators as severally disposed throughout theguys between their terminals. Said hoods .may assulne any appropriate form to overhang the insulators and shield them from snow, rain,- and ice. In the drawings the hood D entirely surrounds the mast like an inverted funnel where the several guys are .attached to the same and incloses any insulators that are there as a part of the guys. The intermediate hood Dalong the guys are shown as box-shaped arrangements around the insulators. In both cases these hoods are of course given interior dimensions and configurations proportioned to the voltage to be used and so that they will not short-circuit the insulators.

As will be readily perceived by the 'arrangements just'described, I obtain an insulator proper wherein the axial pin necessary for its support and connection is immutably fixed and seated within said insulator by reason of the expanded and rigid packing that has been allowed to flow around said pin when in place and hardened. A complete bearing is thus obtained for such pin'and =a fixity in its relation to the insulating material and part that is indispensable in dealing with such material under the conditions supposed. In addition by reason of the exterior and interior spaces, respectively, in the packing H and H asprovided for the creeping tend ency of the twopackings due toexcessive com- 40 that of said member, and firmly held or ce- .Inented in such relation to said member a substantially non-compressible material, together with an outer circumferential coating of like material, the said non-compressiblematerial having sufficient spaces or areas :in

In an insulator for tension-guys, the combination of a hollow insulating member, carrying a coat of a substantially non-compressible material, and an axial supportingpin or part passing through the same with its center or axis substantially coincidental with that of said member and firmly cemented in such position by a surrounding coating or packing of like material, the said material, or coating, in each case containing spaces or areas sufiicient to allow for or take up the tendency of the same to creep when under compression, substantially as shown and described.
