COMPLETE SPECIFICATION.
"Improvements in Electrical Resistance Apparatus."
I, FREDERIC HUGHES, of 20, Paget. Road, West Dulwich. Engineer, do hereby
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention relates to an improved resistance apparatus of a portable character
for use in rendering the current at disposal suitable for the purpose for which it is
required to be used. The invention is intended more particularly for use with such
apparatus as are the subject matter of a Patent granted to me in the year 1895, and
numbered 8135, so that the current at hand can be adjusted to the power of the
lamp on search lights such as are included in the Patent above cited. But although
more especially intended for the purpose just mentioned, it is applicable to any other
use where such an apparatus can be employed. In order to more clearly explain my
invention, I make reference to the accompanying sheet of drawings in which. Fig. 1,
is a front view, Fig. 2, a vertical section, and Fig. 3, a half sectional plan. Similar
letters refer to the same parts wherever they occur.
a is a metal casing preferably cylindrical in shape, and having ventilating holes b
at the top and below. The casing is closed at the top by a non-conducting disc C,
and is at the bottom attached to the wooden or other suitable stand or base d. The
base d is preferably of the form shown having the outstanding bottom e and the
over-hanging upper ledge f. The casing a is provided with a sliding door g which
can be drawn up or up and out by the knob h. In the groove i formed by e and f
are the terminals j k and lm. j and k are connected to wires leading to the plug
connecting the apparatus with the source of electricity, and I and m are connected to
wires leading to the plug connecting the resistance apparatus with the appliance
(such as a search light for casks, bottles and the like) with which the current is to be
employed. and l'are connected with the lamp holder n, and j and m are connected
with one another. k and are connected with opposite poles of the source of
electricity. The holder n is to take lamps such as o of various resistances according
to the work in hand. In order to keep the apparatus steady, a weight p is attached
to or formed with the base. The object of the groove i is to protect the
terminals j k l m. A handle q is provided for convenience in lifting and carrying
the apparatus.
I do not confine myself to the precise shape or configuration, or to the relative
proportions or disposition of parts as shown or described, as any or all of them may
be considerably varied without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-

page_text: closed at the top with a non-conducting disc, and at the bottom with a non-conducting
base in the edge of which is a groove in which are situate four terminals, two of
them being connected by a plug connecter with the source of electricity, and two in
a similar manner with the appliance with which the apparatus is to be used,
provision being made within the casing for a holder to accommodate incandescent
lamps of various resistances, the lamp holder being in connection with one of the
terminals connected with the source of electricity and also with one of those
connected with the appliance to be used, the other two terminals being connected
with each other, the whole substantially as described in the above specification and
exemplified in the accompanying drawings.
2. An electrical resistance apparatus substantially as described in the above
specification and exemplified in the accompanying drawings.
