MEANS'FOR SUPPORTING ELECTRIC DEVICES.
APPLICATION FILED 111.5, 1910} Patented Aug. 4, 1914.
GEORGE A. LUTZ, OF PLAINFEILD, NEW JERSEY.
MEANS FOR SUII POBTING ELECTRIC DEVICES.
Original application fil ed April 13, 1906,
Specification of Letters Patent.
Patented Aug. 4, 1914.
Serial No. 311,477. Divided and this application filed January 5,
1910. Serial No. 536,472.
To all whom it may concern:
Be it known that I, Gnonon A. Low, a citizen of the United States, and resident of Pia-infield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Means for Supporting Electric Devices, of which the fo lowing is a specification.
This application is a division of my application for im rovements in means for supporting electric devices, filed April 13,
1906, Serial No. 311,477..
The object of the invention is to permit an electric lamp or other device to be readily applied to and removed from a conduit and to be supported thereby.
The invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.
. Reference is to be had to the accompanying drawings forming part hereof, wherein,
Figure 1 is a sectional perspective view illustrating my improvements upon a conduit. Fig. 2 is a similar view illustrating the direct connection of a lamp with the foot 7. Fig. 3 is a cross section illustrating the plate or foot 7 provided with means to accommodate wrapping on conductors, and Fig. 4 is a view similar to Fig. 2, illustrating a modification.
Similar numerals of reference indicate corresponding parts in the several views.
The numeral 1 indicates'a conduit, adapt-- ed to receive electrical wires, and it is shown provided with a duct or channelfor the wires, and having opposed grooves l'f to receive covers 2.
At 3 is an arm or support for an electric lamp, to which the fixture for the lamp may be connected in well known manner. Said arm is shown in tubular form for the passage of wires to the terminals of the lam The conduit 1 may be secured to a wal or other support in suitable manner. 3 is to be supported in line with the open side of the channel in the conduit, so that thewires and conduit can be passed through the arm. Arm 3 is shown secured to a plate or foot 7 which foot is shown provided with inwardly curved ends 7, corresponding to the shape ofthe exterior adjacent portion of the conduit, such as the webs forming grooves 1, the foot being so proportioned to the conduit as to grip the same firmly, to
Arm
thereby be supported upon the conduit. The foot may be so made that its end portions 7 a can be sprung over the webs or sides of the conduit to apply it to the latter, or
the foot may be applied by cutting awayv portions of the webs or sides of the conduit. To prevent the covers from being pushed into contact with Wires that pass through arm 3 anabutment is provided to be engaged by the covers.
In Fig. l the abutment 7 is shown as formed by the downwardly projecting end of the arm or tube 3 into the space in line with the covers. But the abutment can be formed in any suitable manner.
As shown in Fig. 2 the lamp socket portion 4 may be connected directly to foot- 7 without the interposed extended arm 3. The walls of the conduit may be pressed inwardly to facilitate connection of foot therewith.
In Fig. 3 the foot 7 is shown provided with a tubular extension 3 for the lamp socket 4, which may be formed by drawing the metal of the foot into tubular form so that the parts 7 and 3 will be integral, the lamp socket being attached to part 3 The part- 3 may be so provided on either of the parts 7 shown in the other figures. The abutment or lug 7 may be applied to foot 7 as indicated in Fig. 2, or may be formed on the ends of part 7' as at 7 in Fig. 3, but said lugs may be omitted. according to requirements. Y i
In cases where the conductors within the conduits are to be joined to branches that pass through the parts 3 or 3" and an insulating wrapping is wound at the joint of the conductors, it thereby produces an enlargement on the conductors which might be too crowded within the conduit under the flat foot or plate 7. The latter may be bentupwardly or raised from the plane of 1 it will be understood that' and placed yertically or in other desired positions, and the covers 2 may be made of flexible material to facilitate their connection with the conduit, or may be of any suitable character attached to the conduit in any desired manner, and such covers can be readily attached on opposite sides of the electric fixture to be applied to the conduit, whereby the wires contained in the conduit may be concealed and protected and ready access to them can be had, 7
While I have shown an electric lamp connected with the conduit it will be understood that anysuitable electric device can be substituted for said lamp.
I do not limit my invention to the precise form of the parts shown and described, as they may be varied without departing from the spirit thereof,
Having now described my invention what I claim is 1. The combination of a conduit having detachable covers, with a foot fitted between said covers and provided with means on op-' posite sides to spring on the sides of the v e conduit to clamp t foot thereon, and means to support an electric device upon,
porting the foot with respect to the conduit,
said foot having a hollow and tubular portion raised above the plane of the conduit, and means connected with said foot for sup porting an electric device on the outer portion of the foot beyond the conduit.
3. The combination of a conduit provided with webs, with a foot having spring-acting portions on opposite sides to clamp on said webs to support said foot upon said webs, said foot having a tubular portion raised above the plane of the conduit, and means for connecting an electric'device with said tubular portion of said foot A. cap for inclosing the junction of branch conductors with conductors inclosed in a conduit, consisting of a tubular portion and with resilient gripping portions on opposite sides of the tubular portion to clamp the cap in position on the conduit. 7 Signed at New York city, iii the county ot New York, and State of New York, this 3rd day of January A. D. 1910.
