CABLE HEAD.

a lication filed Apr i1 1,

The object of my said invention is the provision of'a peculiar and advantageous head" duit with forty five degree and ninety dew gree bends and so {that there will beno liability of the snake being caught in bends, collars 'and cou tilings. a

To the attainment of the foregoing, the

invention consists in the improvement as,

hereinafter described and definitely claimed. In the accompanying drawing forming part of this specification:

Figure l is a side elevation showing my novel head as properly applied to a steel snake. c

Figure v2 is :a vertical longitudinal section of the same with the snake in elevation. Figure 3 is an enlarged cross sectiontaken through the forward portion of the headper se in the plane indicated by the line 3-3 of Figure 1. r

Similar numerals of reference designate corresponding parts in all the views of the drawing.

I show in Figures 1 and 2 a conventional steel snake l which may be and preferably is provided at its forward end with an eye 2.

My invention resides in the head and by a comparison of Figures 1, 2 and 3, the said head will-be understood as comprising two sections 3 of steel or any other appropriate material, hingedly connected at their forward ends as designated by 4. The saidlsections 3 are shaped as illustrated so that when the head is closed as appears in the drawings, the headwill have a forward rounded end 5, and the head will be tapered or gradually reduced in diameter toward its rear end. v The sections 3 are provided with shoulders 4* adjacent to their rearends, and in rear of the said shoulders 43 the sections 3 are provided with semi-circular exteriorly threaded end portions 6. At 7 the sections3 are apertured, and it will be noted that the said sections are equipped with, balls 8, preferably of steel portions of which extend through the apertures 7. It will also be noticed that I equip the lower section 3 with a single ball 8, and the upper section 3 with two balls 8, and that I provide the sections 8 with in-' terior cups 9 for the retention and maintenance of the balls 8 in proper working position; I would further have it' understood i inthis connection that the major portions of the balls '8 are within the section's "3,-a;'nd hence there 1s no liability ofthe said balls beingcasuallydisplaced.

-Tlre'sections being hinged as described at the point 4, the said sections 3 are adapted to be sprung apart so as to permit of the ready-placing of the headover the eye 2 of the snake 1, after the ma nnenbroug'ht out clearly in Figures 1 and 2. After the head is closed over the eye 2 'as-st-ated, the sections 3are secured in closed state ov'er theeye 2 through the medium of; a washer IOand a nut 11; Both washerlOand nut 11 are slotted or split for the ready laterailrplaci ng of the same overthe snake lyand .it will be noticed thatithe washerlO is ada'pted toabut againstzthe shoulders 49?, and t-hat the nut 11 which is preferably ofangular forr'n'exteriorly is adapted to be positioned on and to engage the threads of the end portions 6 of the section 3 so was to strong hold the said end portions 6 together with a-view to preventing casual displacement of the novel head from the eye portion 2 of the snake.

It will be gathered from the foregoing that by virtue of the head having the rounded forward portion and beingta ered from said portion toward its rear en the head may be moved with great facility through a conduit irrespective of any bends that may occur in the conduit. It will also be appreciated that'theballs 8 render easy the pushing of the snake equipped with my novel head, and that while there is no lia bility of the head being casually depressed from the snake, yet when removal of the head is desirable, the same ma be expeditiously and easily accomplishe by displacing the nut 11 and washer :10 and then swinging the rear endportion of the sections 3 apart whereupon the eye 2 maybe withdrawn from the head.

Notwithstanding the practical advantages it of my novel head, the said head is simple and inexpensive 1n construction and in general is well adapted to withstand, usage to which devices used in electricconduit are ordinarily subjected. i

I have described the preferred embodi-' ment of my invention in detail in order to impart a full, clear and exact'understanding I of the said embodiment. I do not desire, however, to be understood as llmiting'myselfto the precise construction disclosed,

my invention being defined by my appended claims within the scope of which modifications maybe made without departure from my invention.

Having thus described the invention, what I claim is 1. A head for snakes and other cables, comprising two sections of concavo-convex form in cross section, said sections being hingedlyconnected together at their forward ends and being provided with comparatively large forward portions and tapered from said portions toward their rear ends and having adjacent to said ends shoulders and exteriorly threaded portions, a split washer mounted on the end portions of the sections and adapted to abut against the shoulders thereof, and a split nut mounted on the threaded end portions of the sections.

2. A head, for snakes and other cables, comprising sections of concavo-convex 'cross section hingedly connected at their forward ends and tapered from their forward portions toward their rear ends and having apertures in their forward portions, cups on their inner sides opposite the said apertures, and balls disposed in said cups and protruding through said apertures and having their major portions arranged within the sections, whereby casual displacement of the and means for detachably holding the rear end portions of the sections together.

4. A snake head comprising concavo-con vex sections 'hingedly connected together at their forward ends and having a coinparatively large forward portion and antifriction devices carried by and protruding from said portions, and means for detachably holding the rear end portions ofsaid sections together. 6 i I In testimony whereof I affix my signature.

JOHN E. SHARP.
