ARTHUR W. JONES, lOF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE THOM- SON-HOUSTON ELECTRIC COMPANY, OF CONNECTICUT.
WIRE-SUPPORT FOR OVERHEAD ELECTRIC RAILWAYS.
SPECIFICATION forming part of Letters Patent No. 522,216, dated J' uly 3, 1894.
l Application inea May 21, 1892. serial No. 433.822. (No modem To all whom it may concern.-
3e it known that I, ARTHUR W. JONES, a citlzen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Overhead Electric Railways, of Wh1chthe following is a specification.
My invention relates to overhead electric railways, and its object is toimprove the construction of the bracket and arm which are used to support the trolley Wire, and especlally to provide an efficient mode of insulating the arm from the bracket and pole.
l The invention consists in certain details of construction as hereinafter described and partlcularly pointed out in the claims.
In the drawings, Figure 1 isa side elevation of a bracket and arm embodying my invention. Fig. 2 is a vertical longitudinal section of the joint between the bracket and the pole, and Fig. 3 is a vertical longitudinal section of the joint between thebracket and the arm.
The pole A is of any suitable construction, and may be tubular, as shown.
The bracket B is of any suitable design, being preferably that of a right angle triangle, as illustrated, with one edge vertical and another horizontal. The vertical edge is provided with a sleeve or sleeves b encircling the pole A, and vertically adjustable thereon by means of a set screw b. The bracket. is provided on its upper edge, preferably at the point where it joins the sleeve b, with a tubular socket b2, the axis of which is in the plane of the bracket, and is parallel with the horizontal edge thereof. A bead b3 surrounds the mouth of this socket. It is annularly recessed on the inside at b4, and the lower portion of its circumference is cut away at b5.
The arm C may be a metallic tube, as shown. Its inner end is connected with the bracket by a plugordowelD of wood or other insulating material driven tightly into the tube and projecting therefrom far enough to havea rm bearing in the socket b2. The end of the tube C is received within the beaded mouth of the socket, but is not in con tact therewith. The bead serves as a watershed to prevent moisture from reaching that part of the wood exposed between the arm and the sleeve, and forming a short circuit.
The outer end of the bracket carries an eye b, through which passes the arm C. A sleeve .E of insulating material is interposed between the eye h6 and the arm, which is clamped by a set screw 57. At each end of the eye h6 is a water-shed bs similar to the one on the socket b2, and projecting beyond the ends of the sleeve E. Y
A plug F, of insulating material, is driven into the outer end of the arm C and serves to support the trolley wire. It may be secured by aset screw f.
Having thus described my invention, what I claim, and desire to secure' by Letters Patent, is
l. The combination with a pole, of a bracket adjustably secured thereon, and having a socket provided with a water-shed, and an eye in line with said socket and having a water-shed at each end, substantially as set forth.
2. The combination with a pole, of abracket having sleeves encircling said pole, a socket, and aneye in line therewith, an arm running through said eye and having a dowel of insulating material connecting it with the socket, and a sleeve of insulating material interposed between the arm and the eye, substantially as described.
3. The combination with a metallic bracket having anfeye provided at each end with a Water-shedding bead, of a metallic arm passing through said eye, and an insulating sleeve interposed between said arm and said eye, and terminating inside of the water-shed, substantially as described.
In Witness whereof I have hereto set my hand this lSth day of May, 1892.
ARTHUR W. JoNEs.
