CONNECTING DEVICE FOR CIRCUIT-WIRE-COVEBING PIPES.
Specification of Iiettersliatent. Patented Feb. 15, 1 910.
Application filed July 24, 1808. Serial No. 509,813.
To all whom it may concern:
- lie it known that I, THOMAS E. MURRAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement; in Connecting Devices for Circuit-\Vire-Covering Pipes, of which the following is a specification.
The invention relates to a connectin device for electrically connecting the ends of the pipe which ordinarily incloses circuit conductors (and which is usually grounded) when said ends are necessarily separated in order to allow of the attachment of branch conductors to the main conductors. The electrical connection of the branch conduc tors to the main conductors is commonly effected in junction boxes or like receptacles wherein the united parts are inclosed and protected bywalls, preferably of insulating refractory material, such as rcelain.
The construction of my pipe connector is such that not only may the endsof the pipe be easily connected to it, but it will not interfere with the attachmentof the branch conductors and box to the main conductors wherever desired.
The accompanying drawings show my pipe connecting device arranged in a junction box, through which the main circuit conductors pass, and which also inclose the branch or local conductors which are connected electrically to the main conductors.
Figure. 1 is a vertical cross section of the box. Fig. 2 is a lo 'tudinal section on the line a: a: of Fig. 1; t e pipe connectingdevice being, in both cases, shown in place. Fi 3 shows the pipe connector separately an the sha represented in F' 3, to produce twoen rings1and2an aconnecting piece 3.
The particular form of junction box .to which said connector is hem diown as applied, is preferably made of porcelain or other refrac ory -Aisthebaseplatc,nnd thecovu. Said in perspective. Fig. 4 'shows a metal blank from which the pipe connector may be cover is arched over at one end and the vertical wall 0 laps over the edge of the base A. Between the cover and the base formed a passage D, through which the mam circuit'conductors E, F, ass. In the base and ektendmg into the passage D are grooves or channels G, H, in which are disposed the metal conducting strips 1, which are clam ed to the circuit conductors as shown at J, ig. 2, and to which are connected the branch or local circuit conductors by means of screw bolts K passing through the base, as shown in Fig. 1.
The pipe connector is put. in lace and the parts are assembled in the fol owing manner. The'portion L of the base which forms the bottom of the passa e D is inserted between the rings 1, 2, o the connector and above the connecting piece 3 which is received ina suitable ogve in the lower surface of the base. e circuit conductors E, F, are then assed through the rings and the metal conducting strips J are clamped to said conductors by means of the screws M. The cover B is then put in place and at its ends overlaps the rings 1, 2, as shown in 2, the rings thus being held in place.
plate is thus 7 The ends of the pipe 0 which incloses the.
circuit conductors are finally respectively inserted in the rings 1, 2, and secured therein 7 by means of the set screws 4.
The .mode here shown of connecting the branch conductors to the main conductors is not essential as any other way may be adopted. Neither is it essential that the portion L of the junction box should be present, since obviously a bottom for the passage D will be formed by the connecting piece 3.
I claim 1. In combination with a circuit conductor and inclosing pipes therein separated at their ends'by an interval, metal rings receiving the oppcsite ends of said pi s, means for clamping said pipeends in sai rin and a bar extending across said. interva and uniting said rin loo 2. In combination with a circuit'conductor and inclosing pipes therein se arated at their ends by an interval, metal ri iigs receiv- 3. In combination with circuit conductors an inclosing metal pipe therefor,
se arated en and branch conduc-. tors to saild main conductors between said ends, a connecting device for said 1 extending through said passage, branch conpipe ends comprising two parallel rings respectively receiving said pipe ends and a bar extending between and uniting said rings.
4. In combination with mam circuit conductors an inclosing metal pipe therefor, having separated ends, and branch conductors between said ends, a connecting device for said pipe ends formed integra y of a single piece of metal and bent mto shape, an comprising two arallel rin respectively receiving said plpe ends an a barextending between and uniting said rings.
5. In combination with a base, a cover forming in conjunction with said base a transverse pasage, main circuit conductors ductors supported on said base and connected to said main conductors in said passage, a pipe inclosin the parts of said main conductors outsi e of said passage, and a device for electrically connectlng the ends of said pipe comprism tremities'of sai passage and receiving said pipe ends and a bar extending below said passage and uniting said rings.
In testimony whereof I have aifixed my signature in presence of two Witnesses.
