PROVISIONAL SPECIFICATION.
Improvements in Machines for Armouring Hose Piping with. Wire.
We, JAMES TINTO, of 4, Queen's Terrace, Old Trafford, Manager, and GEORGE
CARTWRIGHT, of 11, Crow Street, Salford, Foreman, both in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machines for armouring hose piping
with wire and has for its object to provide means which will facilitate either the
fastening of wire (previously) coiled upon the hose piping or the coiling and
fastening of the wire simultaneously in one operation.
To this end we employ on a suitable bed or base a bracket or bearing in which
is mounted a hollow spindle carrying at one end a plate or disc and at the other
end a wheel to which rotary motion is suitably imparted. The face of the said
plate or disc carries blocks formed with suitably shaped grooves or grooved wheels
which are rendered radially, as well as laterally adjustable.
The hose piping to be armoured with wire is placed inside the said hollow spindle
in connection with which an additional support may be employed in front of the
said plate or disc to carry the hose piping. The said grooved blocks or wheels
are adjusted radially in accordance with the diameter of the hose piping to be
armoured and the degree of tightness upon the same and laterally relative to each
other in accordance with the pitch at which the wire has been coiled (previously),
or at which it is to be coiled and fastened upon the hose piping simultaneously.
The said grooved blocks or wheels are adapted to run and exert pressure upon
the wire in a radial direction so as to reduce the wire when coiled previously or
coil it to a less diameter than the hose piping and thus fastening it securely
thereon.
When coiling the wire and fastening it simultaneously upon the hose piping
the bundle of wire is carried by and rotates with the aforesaid plate or disc and
the wire may be drawn through or over a suitable tension arrangement carried
thereon.

Improvements in Machines for Armouring Hose Piping with Wire.
We, JAMES TINTO, of 4, Queen's Terrace, Old Trafford, Manager, and GEORGE
CARTWRIGHT, of 11, Crow Street, Salford, Foreman, both in the County of
Lancaster, 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 to improvements in machines for armouring hose piping
with wire and has for its object to provide means which will greatly facilitate the
fastening of wire upon the hose piping.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section, Fig. 2 a plan, Fig. 3 an end view and Fig. 4 an

page_text: enlarged longitudinal section detached, of a machine for armouring hose piping
constructed in accordance with our invention..
Figs. 5 & 6 are respectively a side view and a section of a detail of our
invention.
In carrying out our invention and referring to the figures generally we employ
on a suitable bed or base a a bracket or bearing b in which is mounted a hollow
spindle.c carrying at one end a plate or disc d and near the other end a toothed
wheel or speed pulley e to which rotary motion is suitably imparted. The face of
the plate or disc d carries blocks f, f, the inner ends of which are formed with
suitably shaped grooves f³, see Figs. 5 & 6, or preferably provided with grooved
wheels f, see Figs. 1, 2, 3 & 4. The blocks f, f, are rendered radially adjustable
simultaneously, similarly to the jaws of a universal chuck, and the block parts f¹
individually laterally by means of the screws f*.
In lieu of rendering the blocks or wheels laterally adjustable they may be
formed in sets with their grooves relatively displaced according to the pitch
desired, as shown in Fig. 4.
The grooves in the block parts for wheels f* in distance from the centre of
the hollow spindle c are each different so that in fastening the wire coil / upon the
hose piping the coil gets reduced to the desired diameter gradually.
?
The machine operates as follows:-
After the wire has been coiled closely and loosely placed onto the hose piping
the same is placed through the hollow spindle c with its end between the grooved
faces of the block parts for the wheels f³, the latter having been previously
withdrawn so as to allow of parting the coils of the wire from each other in distance
according to the distance of the grooves in the block parts f', or wheels f³, whilst
in the meantime the latter are brought together for the purpose of receiving the
wire in the respective grooves. The plate or disc d is then rotated and thereby a
portion of the wire fastened upon the hose piping at the desired pitch and tightness.
After a few revolutions the blocks f,, are radially withdrawn to allow of removing
the hose piping g, the end of which is afterwards again placed between the faces of
the block parts or the wheels f from the front of the apparatus, the pipe itself
being suitably supported if necessary. The block parts or wheels are then
brought into contact with the fastened part of the coil and the plate or disc d
revolved again the armoured part of the hose piping g passing through the hollow
spindle c.
The hose pipe is prevented from rotating by the operator holding it with his
hands.
When rotating the hollow spindle c the grooved block parts for wheels³
in running upon the wire coil h exert a pressure thereon in a radial direction as
may be desired and lay the wire upon the hose piping g without compressing
the hose unduly at the same time fastening it securely..
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
"In machines for armouring hose piping with wire."
1st. The general construction and combination of parts constituting our improve-
*ments operating substantially as and for the purpose set forth.
2nd. The use of a number of grooved blocks or grooved wheels adapted to rotate
conjointly in contact with the periphery of the wire coil so as to reduce the
same in diameter and thereby fasten it upon the hose piping g positioned inside of
the same, all substantially as set forth.
