"IMPROVEMENTS APPLICABLE TO THE COVERS OF CARDING ENGINES WHICH
IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER MACHINES HAVING COVERS OF A
SIMILAR CONSTRUCTION."
My invention relates to carding engines and other machines and consists in
arrangements of apparatus for supporting the covers of such carding engines or
other machines, when such covers are in an elevated position.
For this purpose we attach brackets to opposite sides of the framework of the
carding engine which brackets carry bolts or studs capable of being at times
slidden within the said brackets. The cover of the carding engine is hinged to the
framework of such carding engine. When the said cover is being raised into an
elevated position it arrives in contact with the ends of the before named bolts or
studs and forces them longitudinally within the brackets by which they are carried
the ends of such bolts or studs being formed with inclines for this purpose. When
the aforesaid cover is raised above the bolts or studs beforenamed the said bolts or
studs are forced forward by springs and prevent the descent of the cover aforesaid.
The brackets above referred to support a shaft which extends across the width of
the carding engine such shaft having arms attached thereon which arms are
provided with projections capable of being caused to act against levers mounted
upon the studs or bolts above referred to. When it is desired to lower the cover
above mentioned the attendant slightly raises the said cover from the bolts or studs
by which it was supported and then partially rotates the shaft above referred to
by means of a handle secured thereon so as to cause the projections upon the arms

page_text: attached to the shaft before named to act upon the levers aforesaid upon the before
named studs or bolts and thereby rotate such levers so as to cause inclines upon
the said levers to act against corresponding inclines formed upon the brackets
previously mentioned so as to withdraw the said bolts or studs from under the
carding engine cover aforesaid which may then be lowered.
We employ an additional set of bolts or studs carried and acting as above
described and acted upon by the cross shaft aforesaid for retaining the cover upon
the part of the carding engine opposite to that previously referred to in an elevated
position.
The shaft above referred to extending across the carding engine we enclose
within a tube such tube also acting as a stay to the carding engine framework
when desired.
We also in some cases apply plates or bands to the covers of the carding engine
above referred to, the ends of such plates or bands embracing the cross stay tube
above mentioned and being capable of being turned freely thereon so as to
constitute hinges. When this construction of hinge is employed we cause the bolts
or studs before referred to to support the cover of the carding engine by means
of the said hinges thereby affording a firmer support to the cover before nained.
For simplicity of description I have above confined myself to the description of
my invention as applied to carding engines only but I desire it to be understood
that my invention may he applied to any machine provided with covers constructed
similarly to those of carding engines.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Hurst in the Great Seal Patent Office on the 28th June
1883.

My invention relates to Carding Engines and other Machines and consists in
arrangements of apparatus for supporting the covers of such Carding engines or
other machines when such covers are in an elevated position Fig: 1 of the
accompanying drawing is a vertical side view and Fig: 2 a plan of my invention
as applied to a Carding Engine so much only of such Carding Engine being shewn
as is requisite to illustrate the nature of my invention and the manner in which
the same is to be performed At a is the bend or one side frame of a Carding
engine and at b. c are the covers thereof. These covers are hinged upon a tube d
and are capable of being turned upward thereon in the direction of the arrows
A. B. respectively. To the bend or side frame a of the Carding engine a bracket e
is secured by means of the bolt f upon this bracket e are formed bosses g. h. passing

page_text: through which and capable of being slidden longitudinally therein are bolts i. k.
one portion of each of which is formed of an enlarged diameter, within the cavity
in which the enlarged parts i'. ¹ of the bolts i. k. pass are coiled springs l. m the
ends . m of which press against the enlarged parts . ' of the bolts i. k and thé
remaining ends 12. m² of such springs l. m press against the ends of the cavities
formed within the bracket e. The springs . m this tend to thrust the bolts i. k
respectively in the direction of the arrows C. D. Upon the bolts i. k. are secured
levers n. o the bosses p. q. of which are each formed with two inclines r. 8, which
inclines are held in contact with other inclines formed upon the bosses g. h by
means of the springs l. m. Carried by the bracket e is a shaft t fast upon which
is mounted an arm u provided with two projecting parts v. w which when the
arm u is rotated as will be hereinafter described act against the levers n. 0-Pro-
jecting from the arm u is a handle x by means of which the said arm u and shaft t
may be turned when desired.
I have hitherto referred to the bracket and parts attached thereto which are
secured to one side (E) of the Carding engine but upon the opposite side (F) of
such carding engine is attached another bracket e* and as the parts thereof are
similar to those previously referred to I shall affix to parts corresponding to those
previously described similar letters of reference with the addition of an asterisk (*)
Extending across from the bracket e to the bracket ex is the tube d secured by
means of nuts y, z y* z* to the brackets c. e* and acting as a stay thereto-Within
the interior of the tube d passes the shaft t fast upon the ends of which are mounted
the arms u ux Attached to the covers bc of the Carding engine are plates 1, 2,
1*, 2* secured to the said Covers by screws or other suitable means-Through one
end of each of the said plates 1. 2. 1*. 2x is formed an opening which embraces the
tube d such plates 1. 2 1*. 2* and tube d, constituting hinges by which the covers
b. c are secured to the Carding Engine-In the drawing the covers are shown in
the position which they occupy when down or closed-When it is desired to raise
for instance the cover c and to maintain the same in its raised position, the said
cover c is turned in the direction of the arrow B, upon the tube d such turning of
the cover c will bring the plates 2. 2* into contact with the ends of the bolts k. k*
the ends of which bolts are formed as inclines as shown in the detached view.
Fig: 3 which is a side view of the bolt k and a portion of the cover c and plate 2-
The bolts k*. iix are similar to the bolt k-As the upper edge of the plate or
hinge 2 passes upward the bolts k. k* will be fixed by means of the inclines in
directions opposite to those of the arrows D. D* respectively so as to compress the .
Springs m. mx but upon the cover c being raised so far that the lower part 2* of
the plates or hinges 2. 2× passes beyond the range of the bolts k. k* the said bolts
k. k will be forced outward by the springs in the direction of the arrows D. D*
respectively and will then be capable of supporting the cover c in its elevated
position as shewn by the dotted lines G, by passing beneath the lower edges 2ª of
the plates or hinges 2. 2x-When the cover c is supported in its raised position by
resting upon the bolts k. k* and it is desired to lower the same the operation is as
follows The attendant slightly raises the cover c in the direction of the arrow B
so as to remove its weight or a portion thereof from the bolts k. k* and by means
of the handle x turns the arm u shaft t and arm u* in the direction of the arrow H
such turning of the arms u u* will bring the projections w. w* into contact with
the levers o. o* respectively and cause such levers o. o* to turn in the direction of
the arrow J such turning of the levers o. o* will cause the inclines 88* to slide
the bolts k. * longitudinally within the brackets e. ex in directions opposite to
those of the arrows D D* respectively and thereby withdraw the bolts k. k* from
beneath the plates or hinges 2. 2* and the cover c may then be lowered-As soon
as the plates or hinges 2. 2x have passed the ends of the bolts k. k* the arms u. ux
may be turned into the position shewn in the drawing thereby permitting the
springs m. mx to force the bolts k. k* in the direction of the arrows D. D* respec-
tively so as to bring them into the position shewn in the drawing. The bolts i. i*
act in a manner similar to that previously described in reference to the bolts k. k*,

page_text: for supporting the cover b in its raised position. When it is desired to again lower
the cover b to the position shown in the drawing the attendant slightly raises such
cover b so as to relieve the bolts i. i* of the whole or a portion of its weight and
then turns the arms u. ux by means of the handle x in a direction opposite to that
of the arrow H. thereby bringing the projections v. v* against the levers n n* and
causing such levers to turn in the direction of the arrow K thereby withdrawing
the bolts * in directions opposite to those of the arrows C. C*. respectively in a
manner similar to that previously described in reference to the bolts . *-After
the plates or hinges 1. 1* have been turned downward past the ends of the bolts
2. the arms uu* are placed in the position shown in the drawing thereby
allowing the springs l. 1x to force the bolts i ix into the position shown-When
iny invention is applied to Carding Engines the covers of which are provided with
hinges of ordinary construction the plates or hinges 1. 1. 2. 2× hinged to the
tube d as previously described, may be dispensed with and metal plates may be
secured to the edges of such covers to prevent the ends of the bolts i. ix k. k* from
injuring the said covers and also to furnish a durable part to rest upon the bolts
ii. . * at such times as the covers are maintained in an elevated position-By
withdrawing the bolts by which the cover is retained in an elevated position from
beneath the said cover simultaneously such cover is prevented from being strained
or twisted-The arm u* I furnish with a handle xx so that the attendant may
stand at either side of the carding engine when withdrawing the bolts i. i* k. k*
from beneath the covers-By the use of the above described invention a greater
stability and rigidity is given to the covers of carding engines. Also by the employ-
ment of the above described invention "laps" which may be with or without rods
may be placed upon the upper part of the Carding engine.
I have hitherto described my invention as applied to the covers of carding
engines only but I would have it understood that my invention is also applicable
to supporting the covers of other machines having covers similar to those of carding
engines, when such covers are placed in an elevated position.
Having thus described and ascertained the nature of my said invention and the
inanuer in which the same is to be performed I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent
The use of the arms u. ux having projecting parts v. vx wwx in combination
with and acting upon levers n n* o. o* provided with inclines which levers with-
draw the bolts i. ix k. * that support the covers of Carding Engines or other
machines when such covers are placed in an elevated position substantially in the
inanner herein before described and shown.
In witness whereof I the said William Hurst have hereunto set my hand
and seal this twenty seventh day of June in the year of our Lord one
thousand eight hundred and eighty three.
