INSULATING-B130 CK.

wires running at an angle to each other without changing the position of the block, and is so constructed that the base of various fittings may be attached thereto, the base of the block being'the same for each variety of sizes.

To the above ends, my invention consists of a novel construction of an insulating block having vertical and horizontal recesses in the rear thereof to enable the block to be properly located with respect to the molding, said block having an annular or other opening therethrough, and a. plurality or two pairs of recesses arranged dimetrically opposite to each other, whereby terminals of various sizes can be readily secured in position.

For the purpose of illustrating my inven tion, I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same will be found in practice to give satisfactory and reliable results, although it is to be under stood that the various instrumentalities of which my invention consists can be variously arranged and organized, and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective view of the front of an insulating block embodying my invention, the same being shown in detached position. Fig. 2 represents a perspective view of the rear of the block seen in Fig. 1. Fig. 3 represents a perspective view of the upper portion of a block similar to that seen in Fig. 2, but provided with a metallic or other casing inclosing the same. Fig. 1 represents a rear view of the block seen in Fig. 3, showing the recesses in the rear thereof arranged at right angles to each other. Fig. 5 represents a section on line Specification of Letters Patent.

a20c, Fig. 4. Fig. 6 represents a front elevation showing my novel construction of block in position upon the molding, which may be employed.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings:" 1 represents my novel construction of insulating block, the same being composed of a suitable body portion having in the rear thereof slots or recesses 2 and 3, which are arranged in ver tical alinement, the rear of said block also having therein the slots 4 and 5, which are arranged in horizontal alinement with respect to the slots 2 and 3, it being apparent that said slots 2' and 3 preferably aline with each other, as do also the slots 4 and 5.

6 designates an opening extendingthrough substantially the center of the block, said opening terminating in the radially extending recesses 7 and 8, which are located in the walls 9 and 10 respectively, while the recesses 11 and 12 are located in the walls 13 and 11 respectively, it being ap parent that said recesses 11 and 12 are in horizontal alinement with each other and diametrically located wit-h respect to the recesses 7 and 8, which are also in alinement with each other and located on a vertical line with respect to the re sses 11 and 12.

In Fig. 6, I have shown my invention as assembled with respect to or applied to the metallic or other molding 15, the latter beingin engagement with the walls of the recesses 4L and 5, whereby my novel insulating block can be readily assembled ith respect to said molding. 16 designates a porcelain cap of any suitable or conventional type, which is adapted to be used in connection with my insulating block, said cap 16 being provided with the central opening 17 through which the ends 18 of the conductors 19 may pass, and said cap being provided with diametrically located holes in which the screws 0 other fastening devices 20 of the usual construction may be located, said screws or fastening devices extending through the recesses 12 and 11 respectively, and being secured to any suitable support, as will be desired.

In the construction seen in Figs. 3, 4 and 5, l have shown my novel construction of block, as already described, provided with a metallic casing or band 21, surrounding the same, said casing being cut away at th 11;;

recessed portions so as to leave the strip or portion 22, which appears as best seen in Figs. 3 and 5.

It will be apparent from the foregoing that my novel construction of block can be readily assembled with respect to the molding strips 15, and by reason of the location of the slots 11 and 12 or 7 and 8, provision is made for the employment of porcelain caps 16 of varying diameters and sizes, and that the same block can be readily applied to the vertically extending molding strips 15 by reaSOn of the location of the vertical recesses 2 and 3 therein, as will be understood from Fig. 6.

It will be apparent that by the employment of the metal band covering the four sides of my novel construction of porcelain block, as seen in Figs. 3, 4 and 5, that on a strictly metal molding job, it is necessary to have the molding a complete grounded circuit; therefore, if my novel construction of block is used on the end of a piece of molding and the wood screws that hold the fittings down do not strike the metal in the metal molding, the block will not entirely be grounded,

By my novel construction of porcelain block, I am enabled to use the same as a non-conductor, so that fixtures and fittings may be applied to the metal molding Without the necessity of adding an insulator or insulating joint, as will be apparent to those skilled in the art.

It will now be apparent that I have devised a novel and useful construction of an insulating block, which embodies the features of advantage enumerated as desirable in the statement of th invention and the above descriptiOn, and While I have, in the present instance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

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

1. As an improved article of manufacture, an insulating block comprising a body portion having vertical and horizontal. recesses in the back thereof, a central opening therethrough, and diametrically located recesses extending horizontally and vertically through said central opening.

2. The herein described construction of insulating bloc-k having a suitable body portion provided with vertical recesses 2 and 3 therein, horizontal recesses 4t and 5 therein, said recesses being in the rear of said block, a central opening 6 in said block, and vertical and horizontal. recesses 7, 8, and 11, 12 respectively, located in the body of said block.

The herein described construction of insulating block having a suitable body portion provided with vertical recesses 2 and 3 therein, horizontal recesses 4 and 5 therein, said recesses being in the rear of said block, a central opening 6 in said block, and vertical and horizontal recesses 7, 8, and 11, 12, respectively, located in the body of said block, in combination with a casing inclosing the outer edges of said block.
