INSULATING-CASING FOR WIRE CONNECTIONS.

Specification of Letters Patent.

' Patented Dec. 19, 1905.

Application filed May 27, 1904. Serial lio- 210.063.

vTo all whom it may concern:

Be it known that I, LOUIS A. KLING, a citizen of the United States, and a resident of Elizabeth, in' the countyof Union and State of New Jersey, have invented certain new and useful Improvements in Insulating-Casings for Wire Connections, of which the followingisaspecification. v

The ideaof substituting an inflexible and detachable casing either in theform of sleeves or segments for the more usual way'of insulating wire connections by thoroughly wrapping the spliced wires or joints with'tape is old, but the appliances heretofore 'used for this purpose have either been inapplicable to the varying angles of spliced or joined wires or. the expense hasDrev'ented the extensive use to which they are applicable;

i The main object of my invention, therefore, has been to produce separable and detachable insulating-casings of simplified construction applicable to straight or angular'wire connections, at the same time affording a thoroughly- "waterproof protection for the joints having high insulating qualities.

Another object-of my invention is to pro- "videsuch casings with a plain longitudinal joint between the'meeting edges of the halves which can be readily interlapped and at the same time be easily cleared of any obstruction accumulating upon the recesses of the lower in underground construction.

halves, such as earthy matter, when employed In the accompanying drawings like numerals indicate like parts, andin which- Figure l is a perspective view of a straightway connection with its insulating-casing in position to be assembled. Fig. 2 is a vertical sectional View of' the top orcap portion of the insulating-casing. Fig. 3 is a perspective view of a four-way right-angular splice conare snugly-fitting gaskets.

uninsulated portionsof the wires and sleeve, said casing having threads 6 upon the two extremities thereof. The under half 5 is formed with a projecting portion 6, which conforms with the cut-out portion 6 of the upper half, together forming a rabbet-joint or half-lap water-tight inclosure. 7 is an offset collar formed integral with and within the end of the insulating-casing, the inner surface beiiig so curved asto encompass the insulation of the joining conductors. The top portion 5 is formed with a recessed top or cap 8. adapted to receive the projecting screws4.- 9 9 1O 10 are threaded caps or nuts adapted to screw upon the threads 6and hold the various parts inas.-. sembled position. In Fig. 3, wherein is shown in perspective a four-way oonnection,'the wires or cables have been spliced. The connecting-sleeye has been dispensed with. 'In' this form of. I

connection I preferably make an insulating casing in two semitubular pieces in the form of a cross-though it is ObVlOIlS that the same might be made in four angular pieces.- These pieces 12 and 13 are formed withv the usualpro ecting portion 6 and cut-out portion 6?, together forming a rabbet-joint or half-lap water-tight connection. with and within the ends of the casing are the offset collars 7. The gaskets 9 and-caps or nuts 10 are similar in construction to those described with relation to Fig. 1.

The wires or-cables shown in Fig. 41 are spliced, as above described. The casing here employed is composed of. three component parts 14, 15, and 16 to conform with the peculiar angularjoints of the wires or cables. In other respects the casing is constructed the same as described in Fig. 3 with the gaskets, caps, &c.

In Fig. 5 the branches are at right angles to each other- It is necessary on account of their location to make this insulating-omen ing of three parts, similar in construction to the casing employed in Fig. 4, one part being large'enough to encircle the lower half of the main wire or cable, as indicated at 16', and the lower half of one of the angular,

branches, as indicated at 17, another portion covering half of the other branch, asjindi cated at 18, and the. remaining uninsulat'ed upper portion-of the branch, as indicated at 21, and half of'the upper uninsulated portion Formed integral of the main wire, as indicated at 22. The 7 third part is formed .to fit over the remaining BEST AVAlLABLE COP uninsulated portion of the main wire and branch, as indicated at 19 and 20.- i

In insulating the joints the collars or caps are first slipped on, the proper joint or. con- I ueetion then made, the segment-easing asseml bled and held in position by screwing the l collars or caps thereon. Thus it will be seen i that the joints are protected in a manner that will allow of ready removal for inspection or repair.

Having thus described my invention, what I claim as new herein, and desire to secure by Letters Patent, is4

1. An insulating-casing for wire connections comprising semicircular halves formed with rahbet-joints and with externally-screwthreatled extremities, screw-threaded caps, adjustable upon the extremities of the halves and gaskets fitting within the caps and seating against the extremities of the halves.

2. An insulating-casing for wire connections comprising semicircular halves formed with rabbetjoints, with externally-screwthreaded extremities, and'with collars within the extremities, screw-threaded caps, adjustable upon the extremities of the halves and gaskets fitting within the caps and seating against the extremities and collars of the halves.

3. An msulatmg-casmg for'wire eonneczions comprising senncircular halves formed with semicircularbranches, with ralohet-joints and with externallyscrew-threaded extremities, screw-threaded caps, adjustable upon the extremities of the halves and gaskets fitting within the caps and seating against the extremities of the halves.

4. An insi'ilating-casing for wire connections comprising semicircular halves formed with semicircular branches, with rabhet-joints,

'with externally-serewthreaded extremities,

and with collars within the extremities, screwthreaded caps, adjustable upon the extremities of the halves and gaskets fitting within the caps and seating against the extremities and collars of the halves.

5. An insulating-casing for wire connections comprising a connecting. conductorsleeve, binding-screws passing through the sleeve, semicircular halves formed with rabbet-joints and with externally-screw-threaded extremities,-and witha recessed top upon one of the halves to receive the projecting parts of the screws, screw-threaded caps, adjustable upon the extremities of the halves, and gaskets fitting within the caps and seatingagainst the extremities of the halves.
