SUPPORT FOR AERIAL ELECTRIC GONDUGTORS. I No. 395,814. Patented Jan. 8, 1889.,

NlTE STATES PATENT HENRY H. CUTLER, OF NEWTON, MASSACHUSETTS.

SUPPORT FOR AERIAL ELECTRIC CONDUCTORS.

SPECIFICATION forming part of Letters Patent No. 395,814, dated January 8, 1889.

Application filed July 16, 1888- Serial No. 280,040. (No model.)

To all whom, it may concern: electric conductors. The support, post, or Be it known that I, HENRY H. CUTLER, of upright is shown in this instance as also pro- Newton, county of Middlesex, and State of vided with a bracket or arm for supporting Massachusetts, have invented an Improvean electric lamp at the proper height for street- 5 5 ment in Supports for Aerial Electric Conductillumination.

ors, of which the following description, in con- Figure 1 is a side elevation of a post or upnection with the accompanying drawings, is right for supporting electric conductors ema specification, like letters on the drawings bodying this invention; Fig. 2, a horizontal representing like parts. section, on alargerscale, showing the construc- 6o My invention relates to a support for aerial tion of the joint between the cast-iron supwires, and is especially useful for supporting port and the wrought-iron extension or conthe conductors employed where electriclightt-inuation of the same; Fig. 3, a vertical secing is substituted for gas for illuminating tional detail on line as 00, Fig. 2; Fig. 4: an enstreets. larged detail showing the construction of the 65 One object of the invention is to utilize the upper end of the pole or support and crossexisting lamp posts or supports for the lanarms thereon; Figs. 5 and 6, sectional details tern inclosing the gas-burners of the gas streetof said cross-arms and the means for attachlamps as a portion of the support for the wires ing the insulators thereto; Fig. 7, a detail forming a part of the electric-lighting plant showing the construction of the lamp-sup- 7o that replaces the gas-lamps; and the present porting bracket with the main upright, and

invention is embodied in a support composed Figs. 8 and 9 details to be referred to. of a cast-iron post or upright having its lower The lower or base portion, a a, of the supend embedded in the ground and a tubular port or upright is of cast-iron, being shown upright extension connected therewith and as of the form commonly employed for sup- 75 stiffened at the joint and supported against porting street-lamp lanterns, and having a lateral pressure by tie-rods or braces, the portion, a embedded in the ground and makwhole constituting a trussed upright of sufing a secure foundation for the part aboveficient height to support the electric conductground. Such lamp posts are commonly ing-wires at the requisite distance above the made with aneck, a (see Figs. 2 and 3,) which 80 surface of the ground. receives the base of the lantern proper; and in The invention consists, mainly, in details making the said lamp-posts constitute a porof construction of the devices for connecting tion of a wire-support in accordance with the the lower and upper portions of the post and present invention a block or socket-piece, b, for applying tie-rods or braces thereto, as will is provided, having a socket that fits over the 85 3 5 be hereinafter specified, and in the combinaprojection orneck a and also having threaded tion of such a trussed post with a lamp-supopenings to receive pieces of piping, like an porting bracket adjustably connected thereordinary pipe-fitting. One of said openings with. The upright or support thus utilizes in the block b is directly over the top of the the cast-iron parts, which otherwise have no base portion, a a, of the post, and receives 90. 4o utility when the gas-illumination has been the lower end of a tube or piece of piping, c, dispensed with, and such uprights are as usually of wrought-iron, that extends upward strong and more durable and of better apfrom the base a a to any required heigl1t pearance than the wooden masts or poles comusually one to one half or more times the monly employed for supporting aerial electric height of the base portion, a a. In order to 5 conductors. support the said upper portion, 0, against lat- \Vhile the primary object of the invention eral pressure, the block Z; is provided with is to utilize existing lamp-posts when an electhree or more laterally-threaded sockets, retric-light plant is substituted for gas-illumiceiving laterally-projecting tubular arms d, nation, it is obvious that supports of the same (see Figs. 2 and 3,) which screw in against the I00 construction may be made for supporting teleneck a and thus tightly fasten the block b graph or electric-light wires or other aerial thereto. The said arms cl receive at their outer ends a number of plugs, 6, (see Fig. 8,) having transverse openings 6, through which are passed tie-rods f, which are fastened at their lower ends upon the base a a of the post, as shown at f, Fig. 1, and in Fig. 9, and are fastened at their upper ends in a cappiece, g, placed on the upper end of the extension c, as shown, said cap-piece 9 having a flange, g, provided with openings, through which the tie-rods are passed and then fastened by nuts f bearing on said flange.

The low ends of the tierods are passed through eyes in bolts f screwed into the base portion or lamp post, (see Fig. 9,) and are then fastened by nuts, by which the proper tension may be attained.

The cap-piece g fits upon the end of the ex tension 0, and is fastened there bya set-screw, 9 By this construction the upward extension 0 of the post or supportis securely braced against lateral pressure, making a strong and very rigid support from the ground to the top of said extension.

\Vhen support is required for a single wire only, an insulator may be fastened directly upon the cap-piece g, as shown at h, Fig. 4; but when several wires are to be supported on the post the cap-piece may be provided with a cross-arm, i, consisting of a piece of pipe passed through a transverse socket in the cap-piece g and fastened therein bya setscrew, 2', the said cross-arm. supporting any desired number of insulators, h, which are fastened thereon, as best shown in Figs. 5

and 6.

The cross-arm is bored vertically at the points where insulators are to be attached, and a sufficient portion of the usual wooden insulator-pins, h are fastened upon the said cross-arm by bolts or screws 1L3, passed through the opening in the cross-arm and screwed into the insulator-pins.

\Vhen desired to use the post also asasupport for an electric lamp, a short tube or sleeve, on, (see Fig. 7,) is fitted upon the tubular extension c, which is of uniform diameter, said sleeve on having fastened into it at one side a tubular arm or bracket, 12, which may be bent to the desired shape and extends at any desired distance to one side of the post, the said arm n screwing into the sleeve m and being made fast by a check-nut, o. The bracket may then be moved up or down or turned laterally about the post until the lamp at the end thereof is brought to the desired position, when the bracket is made fast by a bolt or set-screw, p, screwed into the sleeve m until it clamps the same by engagement with the upright c. v

I claim- 1. A post or support for aerial electric conductors, comprising a base portion having its lower end embedded in the ground and terminating at its upper end in a prismatic neck, combined with a socket-piece having a recess that fits upon said neck, a tubular extension having its lower end secured in said socketpiece, and lateral arms fastened in said socket and bearing against the said prismatic neck of the base portion, and tie-rods bearing against the ends of said lateral arms and secured to the base port-ion below said arms and to the tubular extension above said arms, substantially as described.

2. The combination of the cast-iron lower portion and wrought-iron tubular extension thereof, with lateral brace-arms at or near the juncture of said portions, plugs inserted in the ends of said brace-arms provided with transverse openings and set-screws, and tierods passing through said openings and fastened to the cast-iron portion below the wrought-iron portion above said arms, substantially as and for the purpose described.

3. The combination of a post or support composed of a cast-iron lower portion and tubular extension, with braces and tie-rods, with a lamp-supporting bracket connected with said tubular extension and vertically and laterally adjustable thereon, as and for the purpose described. I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
