Improvements in Hose Whipping Machines.
We, WILLIAM ROSE and OTTO FREDERICK VOLLHARD, both of The Metro-
politan Works, Salford, in the County of Lancaster, Fire Engine and Fire Escape
Makers, 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 machines employed for whipping hose upon couplings
and tubes, and for the like purposes.
In such machines as at present constructed it is difficult to prevent the unequal
spacing of the convolutions of wire or cord, and the riding of one convolution upon
another and the object of this invention is to prevent these defects and to construct
the machine in a more simple and compact manner.
The accompanying drawings illustrate a machine constructed according to these
improvements and will be hereinafter referred to. In each of the figures similar
letters of reference are employed to denote similar parts or details of construction.
Figure 1 is a side view of the apparatus,
Figure 2 a sectional plan, and
Figure 3 a front view.
The sleeve
The machine is supported by the head-stock A, a part only of which is shewn in
Figures 1 and 2. This head-stock may be fixed upon a bench or be cast or formed
upon a suitable stand as may be preferred. In the front bearing of the head-stock
there is mounted a rotary sleeve B, longitudinal motion of which is prevented by
the enlarged part and the lock-nuts C, or by similar suitable means.
is internally screwed with a thread having a pitch equal to the pitch of the convo-
lutious of the wire or cord in the whipping. A spindle D passes through the
sleeve and the back bearing of the headstock. The forward part of this spindle is
screwed or chased with a thread to fit the internal thread of the sleeve and is
arranged in such a manner as to be capable of longitudinal motion only. The
rotation of the spindle may be prevented by any known means, such for example as
by making the tail d of the spindle and its bearing non-circular, or by means of a
fast key or the like.
On the sleeve B there is fixed a wheel or disc E, furnished with spokes or
handles e, by means of which it may be rotated by hand. The wheel or disc may
however be driven by power if desired, but we prefer to construct it to be operated
by hand in all cases. A bobbin F is carried upon the wheel or disc E on a spindle
mounted in suitable bearings or supports, and it is fitted with a brake or tension
regulator such as the strap brake G, which should be adjustable for the purpose of
varying the tension when required. The disc E also carries upon the arms H H¹
a guide plate K, which may be conveniently constructed as shewn from two
parallel L-shaped plates kept at the required distance apart by means of distance
pieces or collars arranged between the plates. The guide plate carrics the guide
pulleys 1, 2, 3, 4, over and between which the wire or cord passes and is guided as
hereinafter described. The guide plate is pivoted on the arm H and is secured
upon the arm H' through an are-shaped slot, by a nut fitting upon the screwed
end of the arm. This arrangement as represented by Figure 3, permits the radial
adjustment of the guide plate. The two guide pulleys 3, 4, are arranged close
together and the distance from their point of contact to the centre of the pivot H
is the same as from that 'centre to the centre of rotation of the wheel or disc E.
By loosening the nut on the end of the arm H' the upper part of the guide plate G

page_text: can be moved upwards or downwards, within the limits of the sloty, thus bringing
the guide pulleys 3, 4, nearer to or farther away from the centre of rotation. The
adjustment of these guide pulleys will consequently be directly towards or from
the centre of the coupling.
The front end of the spindle has a face plate or chuck J secured upon it for
holding the coupling or tube whilst the hose is being whipped upon it. An
ordinary three jaw chuck is represented in the drawings and may be conveniently
employed, but we do not limit ourselves to this.
In using the machine, the guide pulleys 3, 4, are adjusted as near as practicable
to the hose on the coupling in order to ensure equal spacing and to prevent riding
of the wire or cord. A supply of wire or cord being upon the bobbin F, its end is
passed round pulley 1, over pulley 2, and between the pulleys 3 and 4, whence it
passes to the hose on the coupling. The apparatus is then rotated by the spokes e
so as to carry the wire round the hose on the coupling which is at the same time
moved longitudinally by the action of the sleeve B on the screwed part of the
spindle B. The apparatus may be rotated in either direction and from either end
of the whipping or it may be always rotated in one direction, the face plate J being
restored to its original position after each operation. If the direction of rotation
whilst whipping be always "against the clock," the guide pulley + may be omitted,
although we prefer to use it in all cases.
To re-fill the bobbin with wire or cord without removing it from its bearings or
spindle, the spindle may have a square projecting end I, upon which a crank handle
may be placed for the purpose of winding on the wire or cord.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A hose whipping machine constructed arranged and operated substantially as
herein before described with reference to the accompanying drawings.
2. In a hose whipping machine, a cord or wire guide consisting of the adjustable
plate K and the guide pulleys therein or thereon, constructed and arranged
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
