SPECIFICATION forming part of Letters Patent No. 556,028, dated March 10, 1896.

Application filed November 16, 1895. Serial No. 569,154. (No model.)

A top or cover piece 22 of wood is I00 secured in position on top of the sections by screws 23 and thumb-nuts 2i, thus greatly strengthening the block, and holes 25 for screws 26 are provided at intervals for securing the block to the wall. Screw-holes and clearance-holes are made wherever necessary in the sections in the customary manner. Changes and modifications may be made by the skilled mechanic in the construction, proportions, and arrangement of sections without departing from my invention, since I do not desire to be limited to the form of block as illustrated in the drawings, as it is obvious that such changes will suggest themselves to suit different requirements of use.

Having described my invention and in what manner it operates, what I claim, and desire to secure by Letters Patent, is-

1. A circuit-block for use in makin branch electrical connections, consisting of two or more sections of insulating material secured together by one or more metallic connections attached to each section, such metallic connections having electrical connection with main feed and branch wires respectively, substantially as set forth.

A eircuit-bloek for use in making branch electrical connections, consisting of two or more sections of insulating material, secured together by one or more strips of metal, attached to each section, such strips having electrical connection with main feed-wires and with branch connections secured to the sections, respectively, substantially as set forthv The combination, in a multiple circuitblock of two or more sections of insulating material, secured together by strips located on each side of a central rib formed by the sections, and feed-Wire connections and branchwire connections respectively, secured to the sections, substantially as set forth.

at. In a circuit-block for use in making branch electrical connections, consisting of two or more sections of insulating material secured together by one or more strips of metal attached to each section, having elec trical connection with main feed-wires, openings in the sides of the sections for branch wires electrically connecting with the strips, substantially as set forth.

5. In a circuit-block for use in making branch electrical connections consisting of two or more sections of insulating material, secured together by one or more strips of metal attached to each section, having electrical connection with main feed-wires; openings through the sections from front to back for branch wires, electrically connecting with the strips, substantially as set forth.

In testimony whereof I have hereunto set my hand this 25th day of September, 1895.
