Improvements in Metal Clips.
I JEREMIAH EUGENE MATHEWSON of Bellefield Works, Sheffield in the County of
York, Engineer, do hereby declare the nature of this invention to be as follows:-
In securing india rubber and other flexible pipes to steam pipes or nozzles, a metal
clip is employed to make a tight joint. The metal clips hitherto used, consisting of a
thick strap, with lugs at each end, which are secured together by a bolt and nut, have
not been successful, inasmuch as when the nut is screwed up, the clip does not adapt
itself to any irregularities in the shape of the tube; the lugs are caused to cant, and
the angles cut into the material; consequently the clip does not properly effect the
object for which it is required.
Now the object of the present invention is to produce a clip in which the above
objections will be obviated.
In carrying out my invention, I take a strip of thin sheet steel, or other suitable
thin sheet material of suitable length, width, and thickness, and to the ends of this
strip I flexibly connect guide blocks or nuts. Through each block or nut I make a
hole to receive a close fitting bolt for drawing the blocks together.
Underneath the ends of the clip, I place a short thin piece of sheet metal (of the
same width as the clip), to prevent friction on the soft material of which the tube is
composed.
The blocks being flexibly connected to the ends of the strip of steel, will, so to
speak, slip readily over the surface of the tube, and no angles will be presented,
when tightening up, to cut into the material, so that the securing will be perfect.
The slips constructed as above described may be of course used for any purpose to
which they may be applied.

COMPLETE SPECIFICATION.
Improvements in Metal Clips.
I, JEREMIAH EUGENE MATHEWSON, of Bellefield Works, Sheffield, in the County
of York, 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 :—
This invention relates more particularly to metal clips for securing india rubber
and other flexible tubes to pipes or nozzles, in order to make a tight joint, but it is
equally applicable to hoops for holding lagging on steam boilers, and also for other
purposes where a metal clip is applicable. The metal clips hitherto used for securing
flexible tubes to pipes, consisting of a metal strap with lugs at each end, which
lugs are drawn together by a bolt & nut, have not been successful, inasmuch as when
the nut is screwed up, the metal strap does not exert an equal pressure all round the
tube, the lugs cant, and the angles cut into the material; consequently the clip does
not properly effect the object for which it is required.
Now the object of the present invention is to produce a clip in which the above
objections will be obviated.
In carrying out my invention, I take a strip of thin sheet metal or other suitable
material of the required length, width, and thickness, and I lap the ends round, or
partly round, metal blocks, which are bored to receive a bolt to be tightened up by a
suitable nut.

page_text: In the accompanying drawing,
Fig. 1 is an edge view of the improved clip;
Fig. 2 is a side view of two lengths of tube with the clip applied thereto; and
Fig. 3 is a section of the tubes, shewing the clip in position.
Figs. 4 and 5 shew slight modifications.
A represents, say, a metal pipe, and B an india rubber pipe to be connected thereto.
C is a flexible strip of metal forming a strap, the ends of which are lapped round
blocks D, in such a manner as to leave the underside of the blocks free. The blocks
are made considerably thicker than the ordinary lugs, and they are bored to receive a
bolt E. The bolt is made to fit the holes in the blocks, and is provided with a nut E',
Fig. 1, or a thumb nut E2, Fig. 2, by which the blocks are drawn together. The
bolt will act as a guide for the blocks, and by reason of the long bearings provided,
the blocks will not cant.
The bolt will also have to pass through the ends of the strap, in which, at either
end, holes will be made for the purpose.
From the fact that the strap is not attached to the blocks on the underside, it will,
as the blocks are drawn together by the nut, bend under the blocks, and thus exert
an equal pressure all round the pipe, and thereby I obtain a perfect connection
between the parts.
A similar effect will be produced by attaching the ends of the strap to the top, or
to the inner side of the blocks, the essential feature being, that the underside of the
blocks shall be free (see Figs. 4 and 5).
To prevent the bulging of the flexible tube between the blocks when tightening up,
I provide a short strip of metal C, the same width as the strap, which may be loose,
or rivetted to the strap C, and which is placed underneath the ends of the clip. This
piece will also prevent friction on the soft outer tube.
The clips constructed as above described will of course grip evenly all round the
pipe, and they are particularly useful for purposes where delicate adjustment is
advantageous, or necessary. They may also be used for any other purposes for which
they are applicable.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The improvements in metal clips as shewn and described, and consisting of the
combination with a flexible strap, of blocks round, or partly round which the ends of
the strap are lipped; a bolt to be passed through the blocks and strap, and a nut for
drawing the blocks together on the bolt, as and for the purpose set forth.
2. In a metal clip, the ends of which are secured together and tightened up by a
bolt and nut, the use of blocks, the undersides of which are free, or not attached to
the strap, as and for the purpose set forth.
