Application filed March 11, 19%. serial n5. 220,363.

To all whom, it may concern:

Be it known that I, FRANK Gr. JONES, a citizen of the United States of America, and a resident of Muskegon, county of Muskegon and State of Michigan, have invented a new and useful 1m rovement in Gable-Terminals, of which the ollowing is a specification.

My invention pertains to cable terminals of the types designed to be mounted upon poles for the termination of cables for distribution of wires, as in distribution to telephone substations. I provide an inclosing wall of oroelain or other insulating material, wit binding post terminals mounted through the wall, the interior of the wall being substantially sealed except at top and bottom. At the bottom I provide .a lead gasket as a convenient means for attaching and sealin the lead sheath of a cable, and when a ca le has been so installed and its conductors connected to the binding post terminals, the, contained space within the an insulating, weather-resistin wall of the cable terminal is poured full of com ound. I then provide ashelf upon W i011 .e terminal may be mounted, and a cover for the terminal. Openings are provided for exit from this housing for wires leading from.

the outside ends of the bindin posts and precautionar means are provi ed to prevent the beatmg in upon the binding posts of rain and snow.

I construct the walls of my improved cable terminal in vertical sections, providing means for attaching as many vertical sections as may be desired. I construct each vertical section of two halves so that in installing the device the halves may be separated to give ready access to the inner ends of the binding post terminals for connecting the cable conductors. I provide also a slotted support, attachin the halves of the terminal to the support y bolts through the slot, so that by means of the slot the terminal may be open and yet held in position convenient for connecting the cable conductors and tor closing the terminal after the connections are made.

lln the drawings: Figure 1 shows a side elevation of my terminal complete with supporting bracket and housing cover, the terminal being shown two sections in height, each section being for ten pairs of conductors, five on each half. 2 shows a sec-' tion through Fig. 1 on the line A A. Fi 3 shows a section of Fig. 1 on the line B Fig. 41 shows a view similar to Fig. 3, but with the can housing removed, and with the halves of the {terminal opened up for connection of {the cable conductors. Fig. 5 shows detail of the block of porcelain or other insulating material.

In 1 and 2,1 is a bracket of cast metal, 2 1s a base block, 3 3 are wall blocks, the pants 2 3 3 being preferably of the same material and 3 3 being necessarily of nsulating material 4 is a sheet metal housmg for protection of the device from the weather, restrained from accidental removal I). the chain 4 and held in "alinement y the periphery/'01" the base block 2 and the wings 31 of {the wall blocks. The base block 2 the housing cover very closely to form a weather seal within the bottom of the houslng. This is particularly true of those portions of the base blocks 2 lie oppesite the walls carr ing the binding post terminals. and lease bl ks are al ned by dowels 555-5 and are united by tie plates, tie

latee 6 6 be ng plane and tie plates 6 6 mg angle plates. The tie lates are attacked t0 the Wall blocks by liblts 7 and to the base blocks by bolts 7; the wall blocks are recessed or countersunk for the heads or nut-s of the bolts, as clearly shown in dotted lines in Fi 2 and as shown at 7 in Fig. 5, and the base blocks are similarly recessed as shown by dotted lines in Fig. 1.

It isevident that as many sections as may be desired may he installed by adding additional wall blocks, such as 3, 3 with dowels 5 and tie plates 6. A thin felt pad 8 is placed between the successive sections, this pad being in two halves to ermit the separation ofthe two halves of the terminal wall atter being built up.

Bmding posts 9 are mounted through the wall bl cks and provided with solder clips 9' on the inner surface of the wall. A groove 9" (see .5) holds the clips in almement while the binding post is being installed. Bosses 9 are cast in the wall blocks to increase the insulation of the hind- 111% posts by surface conformation of the we 1 block.

The process of assembling my improved terminal for service is as follows: The bracket 1 is mounted permanently in the position wluch it is to occupy. Two

base blocks

2, 2 and as many pairs or wall blocks Patented Mar. t3, 1191M.

The wal blocks as are desired are then assembled upon the bracket by means of dowels, tie plate bolts and clamping bolts 10 10. The clamping b0lts l0 10 pass throu h the-angle tie plates, the base blocks and t e slots 10 10 of the cast metal base. The walls then are separated, the bolts 10 sliding in the slots 10 and the halves of the terminal walls are turned into the position shown in Fig. 4. In this osition the clips 9 are readily accessible or soldering the cable conductors. The next step is to pass the end of the cable through the gasket 11 and to unite the (gasket with the cable sheath by pouring sol er into the gasket, or by a wiped joint, or by any means suitable. The cable conductors now are soldered to the solder clips, the bolts 10 are loosened and the two halves of the cable terminal are brought together in their final position; two felt pads 12 12 are placed between the faces of the wall blocks, and the lip ofthe gasket 11 is caused to enter the groove 11 of the lower pair of wall blocks, which groove the lip should fit closely. The two halves of the terminal now are united by through-bolts 13 13, two pairs of through-bolts being provided for each section, and the entire terminal is clamped finally in place upon the bracket by tightening the clamp bolts 10 10. The seal of the cable conductors now is completed by pouring the interior cavity formed by the wall blocks of the terminal full of an insulating, weather-resisting compound.

If desired, the assembly of the wall and base blocks, the soldering in of the cable conductors, and even the pouring of the'compound filling, may be done before the terminal is attached to its supporting bracket, this being a convenient method of procedure where the terminal is to be mounted upon the pole. In such case the bracket is'mounted upon the pole, the cable is cut to the proper length and the terminal is attached to the end thereof; the workman then ascends the pole with the terminal and mounts it upon its bracket. This rocess is permitted by special design of bracket of my invention, in which the supporting face of the bracket consists of two projecting jaws with such an opening between them as will permit the removal of the terminal with its downwardly extending cable intact.

The device being thus assembled, it will be noted from F ig. 3 that openings 14 14 exist bet-ween the projecting ends 2 of base blocks 2 and between the projecting arms 1 of the bracket 1. Jumpers are run from the binding posts 9 through holes 15 in the wings 31, thence downwardly through the openings 14 and thence are available for distribution to any desired points.

It is obvious that much latitude exists in the modification of the details of the terminal of my invention. I have set forth one specific type of terminal constructed in accordance with my invention, but Wish to claim broadly those novel features covered by the claims of this application.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
