PATENT OFFICE.
Specification of Letters Patent.
Patented May 22, 1906.
Application filed September 28, 1904. Serial No. 226,309.
To all whom it may concern.-
Be it known that I, JULIUS CH. TOURNIER, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Rosettes, of which the following is a specification.
The present invention relates to insulating ceiling-blocks or rosettes for protecting joints between branch conductors and main conductors and also serving as a means of suspension for the branch conductor and the devices carried thereby.
The object of my invention is to provide a highly-efficient compact device of this character wh ch shall be of attractive appearance and of low cost of manufacture.
In the accompanying drawings, forming a.
part of this specification, Figure 1 is a plan view of a rosette embodying one formof my invention. Fig. 2 is a longitudinal section on line 2 2 of Fig. 1. Fig. 3 is a transverse ,section on line 3 3 of Fig. 1, and Fig. 4 is a plan of the base-block.
Where electric conductor-wires are carried across a Wall or ceiling, it is customary to support them in grooves 1, formed near opposite edges of narrow moldings 2, which are secured at intervals to the wall or ceiling, according to the location of the joists, and over the wires a removable cap-piece 3 is secured to the molding 2, and in order that my rosette may be connected to the main wires at any point I have desi ned it so that it may be applied to the molding without cutting the latter.
The insulating base-piece 4 is made wide enough to extend across both grooves 1 and has side recesses 5 and 6, from which extend in opposite directions to the top of the base sloping channels or notches 7, into which the main wires may be bent, and in these side recesses 5 6 are arranged metallic contact-strips 8 with bent ends 9, adapted to take under the bends in the main Wires and binding-screws 10, by which the wires are securely held to the contact-strips 8. The lower side of the base is provided with a depending central barrier portion 11, having upwardly-sloping ends 12, which join horizontal end portions 13, and extending diagonally across the depending central portion 11 is a groove 14 for the passage of the branch wires. At opposite ends of the groove 14 are formed depressions 15 and 16, which connect at 17 with the respective side recesses 5 and 6. The contact-strips 8 have attaching portions from portions of the contact-strips 8 are arranged to engage the bottomsof the side recesses 5 and 6 and are secured in fixed positions by screws 20, arranged in countersunk holes 21 near the ends of the central barrier portion 1 1.
The base-block 4 is not attached to the molding 2, but is held in position by the rectangular inclosing shell 22, having a width corresponding to the width of the molding and provided in the center of its closed end with an aperture 23, through which the branch conductor-wires may pass. The aperture 23 is countersunk to receive the usual knot in the conductonwires. The inner surface of the closed end is formed in two planes with inclines connecting them to form a seat for the base-block 4 to rest upon when drawn down away from the molding. The shell 22 is secured to the molding 2 by screws 24 passing through holes near the ends and entering the material of the molding 2. In order to protect these screws from coming into contact with a live wire, the inner end Walls are provided with semicylindrical enlargements 25 and the base-block 4 with corresponding end grooves 26, which serve to center the block relatively to the shell.
It will be observed that the base-block is not subjected to strains either by screws securing it in place or by the weight of the branch wires and devices attached thereto and accordingly may be made very light and compact and thereby permitting an inclosing shell of correspondingly small dimensions to .be used.
I do not desire to restrict myself to the particular form or arrangement of parts herein described and shown, since it is apparent that they may be changed and modified without departing from my invention.
What I claim as new, and desire to secure by Letters Patent of the United States, is"
1. In a rosette for electrical conductors, the combination of a base-block provided at its upper part with side recesses and at its lower part with side depressions which communicate with said recesses, a contact-plate located in the recesses and'depressions on each side of the block, and provided at both ends with binding-screws and an inclosing shell.
2. In a rosette for electrical conductors, the combination of an insulating base-block having in its upper part central side recesses and in its lower part diagonally-disposed side depressions each communicating with a recess, a contact-plate provided With bindingscrews located in each set of connecting recesses and depressions, and .a shell inclosing said base.
3. In a rosette for electrical conductors, the combination of an insulating-base having line-connectors on opposite sides thereof and a central transverse barrier on its lower surface, and an inclosing shell loosely supporting said base.
4. In a rosette for electrical conductors, the combination of an insulating-base having a central transverse barrier on its lower surface, contact-plates secured to the opposite sides of said base and having binding-screws in their upper ends for engaging the line-Wires and in their lower ends for engaging the branch Wires, and an inclosing shell provided with an internal seat for loosely supporting said base.
5. In a rosette for electrical conductors, the combination of an insulating-base having a central transverse barrier provided with a diagonal groove, binding-posts for the linewires located on opposite sides of said base near its upper surface, binding-posts for the branch wires connected thereto and located near the lower surface of said block in line with said groove, and an inclosing shell progided with a seat for loosely supporting said ase.
In witness whereof I have hereunto set my hand this 27th day of September, 1904.
