UNITED STATES PATENT OFFICE.
JASON BAKER, BATTLE CREEK, IOWA.
INSULATOR- PIN.
To all whom it may concern:
Be it known that I, JASON BAKER, a citizen of the United States, residing at Battle Creek, in the county of Ida and State of Iowa, have invented certain new and useful Improvements in Insulator-Pins, of which the following is a specification.
This invention relates to insulator pins and more particularly to that type of insulator pin which is used in connection with cross arms for the stringing of various types of electrical wires such as telegraph, telephone, or the like and has for its primary object the provision of an improved insulator pin which will eliminate many of the objections and defects existing in the type of insulator pin now employed and will provide a simple, inexpensive and practical device of thisnature.
Another object of this invention is the provision of an insulating pin which may be I stamped from a single piece of sheet metal and formed so as to efficiently grip a cross arm or the like and support the insulator in an efficient manner without in any manner detracting from the strength of the cross arm or aiding in the decaying of the same as v is commonly the case with the ordinary wood or metallic pins which are inserted through the cross bars.
With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of reference designate like or corresponding parts throughout the several views, and in which,
Figure 1 is a side elevation of the improved insulating pin; Fig. 2 is a vertical section through the insulating pin; Fig. 3 is an end view of the same; Fig. 4 is a top plan view of the insulating pin ;Fig. 5 is a crosssectional view on the line 5-5 of Fig. 1; and, Fig. 6 is a detail view of a modified form of insulating pin.
Referring more particularly to the draw ings, the numeral 1 designates the main body portion of the insulating pin which is rectangular in side elevation having its four sides 2 formed so as to fit about the cross arm (not shown) of a Wire supporting Specification of Letters Patent.
J {Application filed runezs, 1913;. Serial No. 776,337.11 1?] means (not shown). 1 The sides 2 of the main body portion 1 of the insulatingvpin are constructed of sheet metal which is practically semicircular in cross-section, having flanges 3 extending outwardly from their edges and longitudinally along the full length thereof. The semicircular portions 1 of the sides 2 are depressed as is shown at 5 in the drawings so as to permit the sides 2 to be bent so as to fit about the cross arms (not shown). The semicircular portions 4 form a reinforcementfor the sides 2 and add materially to the strength of the same. The semicircular portion 6 of the side 7 of the .body portion 1 is not depressed at the up per end of the side but extends upwardly beyond the upper side 8 of the body portion 1 and has a plurality of corrugations 9 formed upon its outer surface. .The extreme upper end 10 of the semicircular portion 6 is depressed having a smaller radius than the portion upon which the corrugations 9 'are formed. The upper side 8 of the body portion 1 has a semicircular portion 11 extending upwardly from its inner end and directly opposite the upstanding portion which has the corrugations 9 formed thereupon and is also provided with a plurality of exteriorly formed corrugations 12. The semicircular portion 11 extends upwardly at right angles from the longitudinal lines of the side 8 and parallel with the semicircular portion 6.
The two semicircular portions 6 and 11 are spaced apart, leaving a small opening 13 therebetween and are adapted to be seated within the screw-threaded recess formed in the interior of an ordinary type of glass insulator (not shown). The corrugations serve as a means for securely holding the insulator in place.
By the provision of the space 13 between the two semicircular portions 6 and 11 the latter will efliciently engage and support insulators of different sizes and which have different sized recesses formed therein in that the two sections 6 and 11 may be compressed and forced inwardly toward each other to fit smaller recesses. A washer 10 is also provided with corrugations so as to engage the corrugations 9 and 12 formed upon the two semicircular portions 6 and 11. This washer l0 securely clamps the insulator support upon the cross arm (not shown) and also tends to hold the ment of parts may necessitate -alterationsto which the patentee is entitled, provided such" alterations are comprehended 'thescope'of'wha't is claimed)" WVhat is claimed is 1 An insulator pin stamped from a single piece of semicircular tubing, the edges ofthe same being provided with longitudinally" extending flanges V and flattened non tions at predetermined points to facilitate the engagement of the same about a cross arm, upwardly extending spaced apart parallel a r-ranged members "for engagement with an insulator formed integral With the crossed arm engaging portion, and means engaging-the said upstanding" portions whereby to clamp the semicircular" tubing about a cross arm, andfacilitate insertion into an insulator;-
