PROVISIONAL SPECIFICATION.
An Improved Method for Fastening Electrical Conductors, Wires,
Cables, and the like in Wood Casings by Means of Adjustable
Clips or Clamps.
I, ERNEST COCKBURN DAY, of 362, St. Vincent Street, Glasgow, in the
County of Lanark, North Britain, Engineer, do hereby declare the nature of this
invention to be as follows:--
In these
My invention which relates to "An improved method for fastening electrical
conductors, wires, cables and the like in wood casings by means of adjustable clips
or clamps," especially when such casings are fixed to the underside of ceilings, along
walls, or where there is a great length of span of wires to be covered.
wood casings the wires tend more or less to fall out of their respective grooves, due
to the action of gravity, consequently the casing cover cannot be fastened on unless
the wires are in their proper positions, and it is a matter of great difficulty to keep
them in such positions.
My improved method consists of an adjustable clip or clamp made of a piece of
sheet-steel or other suitable material, about six inches long by one inch wide,
having one end bent up at right angles, the inside face of which end is marked after
the manner of a file, on the other end is applied a sliding or adjustable piece,
having a set-screw to fix it at any desired part of the strip of sheet steel, this
sliding or adjustable piece is also provided with a thumb-screw for the purpose of
fastening the clip or clamp on to the casing during the operation of fixing up the
cover, and thereby saving a lot of time and annoyance, compared with the present
method of fixing up temporary pieces of wood.
The clip or clamp need not be taken off for each length of covering, but it can be
slid along the casing, by slackening the sliding or adjustable piece.
To enable the clip or clamp to be removed from the casing, when such casing is
run in awkward positions, the clip or clamp is preferably made with two sliding or.
adjustable pieces.

COMPLETE SPECIFICATION.
An Improved Method for Fastening Electrical Conductors, Wires,
Cables, and the like in Wood Casings by Means of Adjustable
Clips or Clamps.
I, ERNEST COCKBURN DAY, of 362 St. Vincent Street, Glasgow, in the County
of Lanark, North Britain, 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 :-
The invention relates to an improved method for fastening electrical conductors,
wires, cables and the like, in wood casings, by means of adjustable clips or clamps,
and is especially applicable to wood casings which are fixed to, the under side of
ceilings, along walls, or where there is a great length or span of wire to be covered;
and the object of the invention is to provide means whereby the conductors
wires, cables and the like may be temporarily held in position preparatory to
being enclosed within the casings, in a manner more convenient than at present
obtains.

page_text: In the method of securing such conductors within these wooden casings as at
present for the most part employed, considerable difficulty is experienced in keeping
the wires temporarily in their respective grooves, until the cover of such casing is
attached, and especially is this the case under the conditions described, wherein
gravity, or a tendency to spring, often cause the wires to be displaced.
To remedy this, and to effect my improvements, I provide a strip or plate of
sheet steel, or other suitable material, about six inches long by one inch wide, for
most ordinary purposes, (although other dimensions may be employed), which strip
or plate has one end bent up at a right angle, or any other effective angle, the
edge, or inside face of such end being serrated, or roughened, for the purpose of
gripping.
In this strip or plate of metal, I cut or otherwise form a slot, which extends, by
preference, from within a convenient distance of the turned up end, to the other
extremity of the plate; and I provide a separate adjustment piece capable of
sliding within this slot, which adjustment piece may be secured at any point in the
length of such slot, by thumb-screw or other device, and is formed with a serrated
or roughened jaw corresponding with and opposed to the turned up end of the strip
before mentioned.
By preference, I so form this adjustment piece that one end thereof, when the
thumb-screw is slackened, will fall by gravity, and tilt up the jaw; by which
means, when the apparatus is brought in contact with the conductor casing, the
grip upon the wood may be obtained by tightening the set-screw, and so force the
adjustable jaw into its proper position.
The clip or clamp thus attached to the casing will provide a temporary support,
to keep the conductors or the like in their proper places until the permanent covers
can be loosely attached, when the adjustment piece may be slid along its slot, by
slackening the set-screw, and so removed from the plate, which latter may then be
withdrawn from between the casing and its cover, after which the cover may be
completely tightened up. The clip or clamp need not in all cases be taken off
entirely for each length of covering, but where permissible it can be slid along the
casing, by slackening the adjustable piece.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
