Improvements in Looms for Weaving Fire and the like Hose.
I, FRANCIS MCCLELLAN, of 60, Boundary Street, Pendleton, in the County of
Lancaster, Hose-pipe Weaver, do hereby declare the nature of this invention to be
as follows:-
This invention relates to that class of looms for weaving fire and the like hose
for conveying fluids, known in the trade as combination looms, i.e. where the healds
are operated by motive power and the slay by hand.
The object of my invention is to obviate the said hand labour by providing
automatic means for operating the slay whereby the weft is beaten up more
regularly and an evenly woven hose is produced, besides increasing the production
and reducing a great deal of labour.
To this end I connect to the back of the slay two arms the free ends of which
are each furnished with a pin projecting on each side thereof and carrying anti-
friction bowls adapted to run in the grooves of a two part cam of peculiar
construction which cams impart motion to the slay. The said two part cams are
fixed upon a rotating shaft suitably positioned, say on the shaft interposed between
the driving shaft and the tappet shaft. Each of the said cams has two grooves
facing and in outline corresponding with each other a space being provided to
admit of the aforesaid arms working between the same. The said cam grooves are
adapted to receive the anti-friction bowls of the said arms and are so formed as to
impart two strokes to the slay during one revolution, viz. a short stroke when
beating up whilst the shuttle is in the shed and a long stroke when out of it. For
this purpose I form the groove part on one side of the centre of rotation of the
said cam in length equal to the stroke required for beating up the weft when the
shuttle is in the shed and the groove part on the other side of the said centre in
length equal to the stroke required for beating up when the shuttle is out of
the shed.
If desirable the aforesaid cam groove parts which effect the beating up whilst
the shuttle is in the shed may be so formed as to beat up twice during that time.

Improvements in Looms for Weaving Fire and the like Hose.
I, FRANCIS MCCLELLAN, of 60, Boundary Street, Pendleton, in the County of
Lancaster, Hose-pipe Weaver, 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 that class of looms for weaving fire and the like hose
for conveying fluids, known in the trade as combination looms, i.e. where the healds
are operated by motive power and the slay by hand.

page_text: The object of my invention is to obviate the said hand labour by providing
automatic means for operating the slay whereby the weft is beaten up more
regularly and an evenly woven hose is produced, besides increasing the production
and reducing a great deal of labour.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. is a vertical section at line A-B of Fig. 2. Fig. 2 a sectional plan and
Fig. 3 a sectional front view of a loom for weaving fire and the like hose constructed
in accordance with my invention. Fig. 4 is a side view of a modification of the
slay cam belonging to the same.
a are the frame sides and b is the slay.
In carrying out my invention and referring to the figures generally I connect or
secure to the back of the slay b two arms c the slay being, instead of suspended,
arranged to slide on the frame sides or on brackets a' secured thereto, see more
particularly Fig. 3. The free ends of the arms c are each furnished with a pin d
projecting on each side thereof and carrying anti-friction bowls e adapted to run in
the grooves f of a two part cam g of peculiar construction which cams impart
motion to the slay b. The two part cams 9 are fixed upon a rotating shaft h
suitably positioned, say on the shaft interposed between the driving shaft and the
tappet shaft. Each of the cams 9 has two grooves facing and in outline corre-
sponding with each other and each formed on a disc g', a space i being provided to
admit of the arms c working between the same. The cam grooves are adapted
to receive the anti-friction bowls e of the arms c and in one instance, see Figs. 1 & 2,
are so formed as to impart two strokes to the slay b during one revolution, viz. a
short stroke when beating up whilst the shuttle is in the shed and a long stroke
when out of it. For this purpose I form the groove part f' on one side of the
centre of rotation of the cam g in length equal to the stroke required for heating
up the weft when the shuttle is in the shed and the groove part 2 on the other
side of the said centre in length equal to the stroke required for beating up when
the shuttle is out of the shed.
If desirable the aforesaid cam groove part f¹ which effects the beating up whilst
the shuttle is in the shed, may be so formed as to beat up twice during that time by
forming it with a depression f³, see Fig. 4.
By leaving the shuttle in the shed the weft is beaten up closer and without injury
to the fibres as would be the case when beating up to the same extent whilst the
shuttle is out of the shed.
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-
"In combination looms for weaving fire and the like hose."
1st. The use and application of cams each formed with a long and one or two
short strokes, the long stroke being adapted to actuate the slay or beat up the weft
whilst the huttle is out of the shed and the short stroke or strokes whilst the
shuttle in the shed, for the purpose of producing an automatic and regular
beating up of the welt, all substantially as set forth.
2nd. The general construction and combination of parts constituting my
improvements, all substantially as set forth.
