v oall whom, it may concern: preferably at right angles to each other, as Be it known that I, OLAF STROM, of the city shown. There is a smoothly-finished upright of Brooklyn, in the county of Kings and State axis on this base-casting, having an offset at of New York, have invented a certain new about the mid-height, for purposes which will 5 5 and useful Improvement in Combination-Fitpresently appear.

The main feature in my improved fitting is Referring now more especially to Fig. I, it a main or base casting (adapted to be fixed will be seen that the sockets D and E are ar- 20 to a wall) bored or cored out for the gas-conranged the formerimmediately above the latduits and for passages through which the ter.

bored or cored out within this main casting, In drilling the gas-passage a it is necessary to commence from the exterior of the casting A. Therefore to close the opening and also to bind the socket D properly to said casting, I

use a screw (Z and washer (P, as shown.

It is important that there should be no frietion between the sockets D and E. Therefore I make the bearing for the socket I) smaller than for the socket A and produce a corresponding offset in the central axis. The lower hearing has a little greater height than the depth of the socket. By this means I so arrange their bearings upon the casting A that there shall be a space c between them, as seen in Fig. 1. This construction insures that either pipe may be turned or swung horizontally to any desired extent when required without moving the other.

The modification, Fig. 2, shows the same essential features, save that the gas-cock F is dispensed with, and the socket E for the electric wires 0 is journaled upon a part of the casting A at that side of the center which is opposite to the bearing of the gas-socket D, a screw 6 and washer a (similar to those marked d and d respectively) being employed to retain this socket E in place, while allowing it to move in like manner to D. In this modification the channel I) for the slack wire a is not annular, as in Fig. 1, but is simply formed in one side of the extension from the casting A, thence opening into the conduit e. To bring the branch pipe E close underneath the pipe D, I form an elbow E upon the socket E, and in this make a passage 6, usually at right angles to that marked 6, and leading thence into the horizontal branch pipe E.

To keep the pipes D and E the proper distance apart to stiffen and also lock them together, so that they may swing together upon their bearings, I use the locking device G, (shown in Figs. 1 and 3,) or its equivalent, such as is illustratedin Fig. 4. Upon each of the pipesI secure collars or segments 9 g at any suitable point, such as the mid-length of the branch, and arrange upon the opposing faces of these collars short screwed projections g, extending into close proximity with each other, so as to allow of their joint engagement with an adjustable screwed coup ling g. This latter is adapted to be turned by hand, and is adjusted-so as to engage with both of the screws g g when both branch pipes are to be kept together, and with. one or the other alone when the gas-bracket and electric-light branch are intended to be moved separately.

I claim as my in vention I 1. In combined electric and gas fittings, two offsets arranged on the axis with a space between the electric arm below and the gasarm above such oit'set, giving an independent bearing to each, substantially as described.

2. The combination, with the branch pipes D and E, of a locking device composed of two screws g 9', one on each pipe, and a nut adapted to serve as aeonneetion between said screws, substantially as and for the purpose specified.

3. In combined electric and gas fittings, the key for gas drilled from one end of plug through screw and washer and far enough into said plug to connect with vertical gasway in stationary fitting, substantially in the manner set forth.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.

OLAF Q'IROM.
