Year: 1884

page_text: I, FERDINAND BOSSHARDT of the firm of Bosshardt & Grant Mechanical & Con-
sulting Engineers & Patent Solicitors of 24 & 32 Bulls Head, Exchange Chambers
Market Place Manchester in the County of Lancaster, do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WASHING
HANKS OF YARN which has been communicated to me from abroad by Johann
Baptiste Straub of Mülhausen in the Empire of Germany to be as follows:-
"
This invention relates to that class of machinery or apparatus for washing
hanks of yarn in which the banks are placed upon one or more revolving rollers
and drawn through water or other liquid contained in a vat or cistern, such as are
used in Bleach & Dye works. This method of washing is objectionable because
the water does not penetrate the yarn sufficiently to wash the same thoroughly.
To remedy this defect my invention has for its object to bring water under
pressure, into contact with the yarn and to beetle the same during the time of
washing. To this end I mount a more perforated hollow roller of any suitable
section, diameter, width and length in bearings on a suitable frame. The shaft of
the said roller is formed hollow and provided with a bevel wheel which is arranged
to gear into another bevel wheel keyed on the end of a vertical shaft to which
rotary motion is suitably transmitted. Below the perforated roller another roller
is employed which keeps the yarn expanded and made adjustable on the frame in
order to suit the length of the hank. Above the perforated roller a pressure roller
is suspended in a lever hinged to the frame and riding on the top of the yarn and
the perforated roller which causes the yarn to be pressed constantly, and thoroughly
impregnated with the water or other liquid.
The pressure roller may be disengaged by lifting the hinged lever from which it
is suspended.
On the vertical shaft a cam is arranged to work a lever arm which is suitably
hinged to the frame the free end thereof extending outside to the hank at about
half of its length. A corresponding arm which rocks on a pin on the frame, and
retained in its position by a spring, is arranged opposite to the said lever arm.

the lever arm worked by the cam and the corresponding lever situated opposite,
the former beetling continuously against the latter. At the side of the top roller
a hand lever is arranged which is connected with a valve employed to control the
admittance of water or other liquid to the hollow perforated roller and to the
driving gear of the apparatus or machine which when actuated will stop the supply
of water or rotation of the perforated roller in order to enable the removal of the
hank. The said hand lever may be connected by means of a link with the lever
carrying the pressure roller so as to disengage the pressure roller and stop the
supply of water or other liquid and rotation of the perforated roller simultaneously
in one action.
The described arrangement may be repeated as desired and the rollers enclosed
in a casing in order to catch the water expelled during the operation of washing.

page_text: I FERDINAND BOSSHARDT of the firm of Bosshardt & Grant Mechanical &
Consulting Engineers, and Patent Solicitors of 24 & 32 Bulls Head Exchange
Chambers Market Place Manchester in the County of Lancaster, do hereby declare
the nature of my Invention for IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR WASHING HANKS OF YARN "which has been communicated to me from abroad
by Johann Baptist Straub of Mulhausen in the Empire of Germany Engineer and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to that class of machinery or apparatus for washing hanks
of yarn, in which the hanks are placed upon one or more rollers and drawn through
water or other liquid contained in a vat or cistern such as are used in Bleach or dye
works.
This method of washing is objectionable, because the water does not penetrate
the yarn sufficiently to wash it thoroughly.
To remedy these defects my invention has for its object to bring water under
pressure into contact with the yarn and to beetle the same during time of washing.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference
corresponding letters indicating like parts in the various figures.
Fig 1 on the said drawing represents a front view of an apparatus for washing
hanks of yarn. Fig 2, is a side view of the same. Figs 3 and 4 are enlarged
sections of the upper part of the apparatus.
In carrying out my invention I mount one or more perforated hollow rollers a of
any suitable size and section in a bearing bon a frame c. The shaft d of the
roller a is formed hollow and provided with a bevel wheel e which is arranged to
gear into another bevel wheel f keyed on the top end of a vertical shaft the lower
end being provided with a bevel wheel h gearing into another bevel wheel i keyed
on one end of the horizontal shaft k rotating in the frame c and provided on the
other end with a fast and loose pulley and m. Below the perforated roller a
another roller n is employed which keeps the yarn expanded and is made
adjustable on the frame c in order to suit the length of hanks to be washed.
Above the perforated roller a pressure roller o is suspended on a lever p hinged to
a bracket q on the frame c and riding on the top of the yarn and the perforated
roller a which causes the yarn to be pressed constantly and thoroughly impregnated
with the water or other liquid. The pressure roller o may be disengaged by
lifting the binged lever p to which it is connected, see dotted position shown in
Fig 2,
On the vertical shaft g a cam r is arranged to work a lever arms which is
suitably hinged to the frame c by means of the pin t and constantly pressed against
the said cam by means of the spring t¹. The free end of the said lever arm extends
outside to the bank at about half way of its length and is provided with a wooden
or other facing u. A corresponding lever arm which rocks on a pin w fixed on

page_text: the frame c and is retained in its position by means of a spring x which presses
against one end of the said lever arm v, is arranged opposite to the lever arm 8.
When the bank is set in motion by the perforated roller a, the yarn passes between
the lever arms worked by the cam r and the corresponding, lever arm situated
opposite to the former, and it will be continuously beetled by the lever arm s
against the said lever arm v, the spring x acting as buffer for the latter.
At the side of the top or pressure roller o, see Fig 2, a hand lever is arranged
on a stud z fixed to a bracket on the frame c and connected with the valve a¹
situated at the end or inlet of the hollow shaft d and employed to control the
admittance of water or other liquid by means of the lever a³ rocking on a stud d
rod a³ and lever at. The said hand lever y is also brought in connection with the
driving gear or bevel wheel h in order to instaneously stop the rotation of the
roller a, and cut off the water by means of the bent lever bi fixed on the stud a³
which connects the lower end of the rod a³ with one end of the lever a², rod b² and
clip 63, which latter clips the boss of the bevel wheel causing the latter to engage
or disengage the bevel wheel i and thus stopping, or rotating the roller a in order
to enable the removal and replacing of the banks when required.
The said hand lever may be connected to the lever p carrying the pressure
roller o by means of a link c¹ so as to disengage the pressure roller; stop the supply
of water or other liquid and rotation of the perforated roller a simultaneously in
one action. Another hand lever d³ is hinged on a pin d³ fixed to the side of the
hand lever y and provided with a slot d' at its lower end which engages the beading
of the frame c and causes the lever y to retain its position for the purpose of letting
the valve a' either remain open or closed and the bevel wheel i in or out of gear
respectively.
The described arrangement may be repeated as desired and the rollers enclosed
in a casing in order to catch the water expelled during the operation of washing
the hanks.
