IMPROVEMENTS IN YARN BEAMING MACHINE
Year: 1885

page_text: I, ALFRED HITCHON Globe Iron Works Accrington Lancashire Machine Fitter
do hereby declare the nature of my invention for IMPROVEMENTS IN YARN BEAMING
MACHINE to be as follows:-
The same being an improvement on and for like purposes as Letters patent
granted to Edmund Tweedale Dec. 1877. No 4708 wherein are illustrated (and
are extensively used) a pair of spiral incline bosses for the purposes of pressing
together the main driving pulley and its corresponding friction plate. The
expanding of these spiral incline bosses is caused by one being turned round a part
of a revolution to set, the machine in action, and is reversed by the machine itself
by the knock off lever, when the motion of the machine is arrested.
By this invention I make these aforesaid incline bosses and levers serve a twofold
purpose viz-by making use of an additional smaller friction on the same shaft as
the above named main driving for the purpose of giving a separate disconnection
of driving parts that drive the nip rollers thereby giving the convenient option of
letting the nip rollers and all gearing for driving the same remain at rest till the
spiral incline bosses expand and thereby compressing both the frictions with the
one expansion for setting on the machine which is already made use of for the one
main driving friction only, therefore dispensing with the special levers and tooth
clutch boxes as at present used to accomplish the aforesaid object.

page_text: I ALFRED HITCHON of Globe Works Accrington, in the County of Lancaster,
Machine Fitter do hereby declare the nature of my invention for IMPROVEMENTS
IN YARN BEAMING MACHINES, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statements-
This invention relates to improvements on machinery for which Letters Patent
were granted to Edmund Tweedale Dec. 1877.-N° 4708, wherein are illus-
trated and extensively used a pair of spiral inclined bosses for the purpose of
pressing together the main driving pulley and its corresponding friction plate.
The expanding of these spiral incline bosses is caused by one being turned round
a part of a revolution to set the machine in action, and is reversed by the machine
itself by the knock off lever when the motion of the machine is arrested.
By this invention I make these aforesaid incline bosses and levers serve a
twofold purpose, viz by making use of an additional smaller friction on the same
shaft as the above named main driving for the purpose of giving a separate dis-
connection of driving parts that drive the nip rollers, thereby giving the convenient
option of letting the nip rollers and all gearing for driving the same remain at rest
till the spiral incline bosses expanded and thereby compressing both frictions with
the one expansion for setting on the machine which is already made use of for the
one main driving friction only; therefore dispensing with the special levers and
tooth clutch boxes as at present used to accomplish the aforesaid object.
Such being the nature and object of this my said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which
Fig. 1. is a front elevation of part of a yarn beaming machine having my
improvements applied thereto.
Fig. 2. is an end elevation of Fig. 1.
Fig. 3. is a view enlarged of part detached and drawn to enlarged scale.
At 1. is the main driving shaft on which are the inclined surface bosses 2.
and 3. on the said shaft I fasten the friction plate 4. so that when the bosses 2.
and 3. are so moved that their inclined or cam surfaces operate, the said plate 4. is
relieved of its compression of its gear wheel 5. (see Fig. 3.), and which being loose
on its shaft 1., thus the driving the wheels 7. and shaft 8., and consequently the
rotation of the nip rollers 9. 10. is suspended until the inclined bosses 2. 3. are
again moved into position for driving the machine and by such movement the
plate 4. is again brought into compression with and for the purpose of driving the
wheels 5. 7., shaft 8. and nip rollers 9. 10.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1.-A divided tooth wheel (as shewn by illustration Fig. 8. to an enlarged scale)
forming a separate friction to the main driving frictions 2. 3. and for purpose
herein set forth and as illustrated by the annexed drawings.
2. The friction plate 4. toothed wheel 5. combined with and operated by means
of the inclined bosses 2.-3 for purpose herein described and as illustrated by
annexed drawings.
