as follows:-
The object of our Invention is to facilitate the manipulation or tending of such
machinery, and to increase the efficiency of the mechanism actuating or connected
with the tools and the table, on which the hides, leather, or other material to be
operated upon is placed.
Our Invention in the First place refers to the means for facilitating the raising and
lowering of the table. Until the grant to the above named Joseph Hall of Letters

and numbered 2262; tables on which the material was placed and having combined
horizontal motions had never previously been so arranged, that they could be raised
or lowered to bring the work nearer to or further from the tool. Now this first
portion of our Invention comprises further means for raising and lowering such tables
as have combined horizontal motions, and consists in raising and lowering the table
by means of screws, cams or eccentrics, or levers; such mechanism raising either the
table alone, or also the cross or main carriage.
This portion of our Invention also, comprises the use of wedges for raising and
lowering the table, such wedges being moved in and out in a radial direction (to and
from the centre pin of the turntable).

page_text: Secondly to the means for automatically moving the table in a horizontal direction.
When the table by means of main and cross carriages has two straight horizontal
motions, generally at right angles to each other, these I move backwards and
forwards, automatically, from some moving part of the machine, either by rack and
pinion (or worm), travelling ropes or chains, or screws; the upper carriage being
moved across and the bottom carriage against the tool. When desirable the bottom
carriage is made to work automatically across the tool by the same means. Where
the main carriage has a circumferential (usually miscalled radial) motion, I move the
same by travelling ropes or chains, or by rack motion; actuated, automatically from
some moving part of the machine, or by hand.
Thirdly to mechanism for operating the tool from the connecting rod in such a
manner, that during the first small fraction of the working stroke the tool is allowed
gently to descend on the work, and then passes over it with a uniform pressure, until
the last fraction of the stroke, when the tool is as gradually and gently raised from
the work, and kept raised during the whole of the return stroke.
The mechanism consists of a projecting piece or wiper attached directly or indirectly
to the connecting rod, such projecting piece working in conjunction with a suitably
curved surface or groove formed in or attached to the hinged lever carrying the tool.
Or the suitably curved surface or groove may be attached to the connecting rod and
act upon the tool lever through the intervention of projections or levers, or directly.
The tools may be placed side by side, or behind (i.e. tandem fashion), and operated
singly or alternately.

Brushing.
We JOSEPH HALL of Burley Engine Works Kirkstall Road Leeds Engineer and
ANN HALL of Dyson House Burley Wood Leeds both in the County of York
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:
The object, of our Invention is to facilitate the manipulation or tending of such
machinery and to increase the efficiency of the mechanism actuated or connected with
the tools and the table, on which the hides, leather, or other material to be operated
upon is placed.
Our Invention in the first place refers to the means for facilitating the raising and
lowering of the table. Until the grant to the above named Joseph Hall of Letters
Patent for an Invention entitled "Improvements in Machinery employed in the
manufacture of leather for Setting Scouring, Striking or Pinning, Printing, Rolling,
Slicking, Fleshing, Unhairing, Whiting, Shaving and Brushing, dated 3rd May 1883
and numbered 2262; tables on which the material was placed and having combined
horizontal motions had never previously been so arranged, that they could he raised
or lowered to bring the work nearer to or further from the tool. Now this first
portion of our invention comprises further means for raising and lowering such tables
as have combined horizontal motions, and consists in raising and lowering the table
by means of screws, cams or eccentrics, or lovers; such mechanism raising either the
table alone, or also the cross or main carriage.
This portion of our invention also comprises the use of wedges for raising and
lowering the table, such wedges being moved in and out in a radial direction (to and
from the centre pin of the turntable).
Secondly to the means for automatically moving the table in a horizontal direction.
When the table by means of main and cross carriages has two straight horizontal
motions, generally at right angles to each other, these we move backwards and
forwards automatically from some moving part of the machine, either by rack and
pinion (or worm), travelling ropes or chains, or screws; the upper carriage being
moved across and the bottom carriage against the tool. When desirable the bottom
Where
carriage is made to work automatically across the tool by the same means..
the main carriage has a circumferential (usually miscalled radial) motion, we move
the same by travelling ropes or chains; or by rack motion actuated automatically
from some moving part of the machine.or by hand.
Thirdly to mechanism for operating the tool from the connecting rod, in such a
manner, that during the first small fraction of the working stroke, the tool is allowed

page_text: gently to descend on the work, and then passes over it with a uniform pressure, until
the last fraction of the stroke when the tool is as gradually and gently raised from the
work, and kept raised during the whole of the return stroke.
The mechanism consists of a projecting piece or wiper, attached directly or in-
directly to the connecting rod, such projecting piece working in conjunction with a
suitably curved surface or groove formed in or attached to the hinged lever carrying
the tool. Or the suitably curved surface or groove may be attached to the connecting
rod and act upon the tool lever through the intervention of projections or levers, or
directly. The tools may be placed side by side, or behind (i.o. tandem fashion) and
operated singly or alternately.
And in order that our invention may be more completely understood reference is
given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Plate 1 shews the mechanism, referred to in the third part of this specification, for
operating the tool from the connecting rod. Fig. 1 is a longitudinal section of the
tool carriage on line A. B. Fig. 2 is an end view. The mechanism consists of a
projecting piece or wiper a attached to the connecting rod of the machine. Tho
projecting piece a works in conjunction with a suitably curved surface or groove
formed preferably on a separate adjustable block c. The block c is attached and
adjusted in position on the hinged lever d carrying the tool e. The drawing shews
the tool carriage provided with two tools e, so that the leather is acted upon during
both the forward and backward motion of the carriage. The exact shape of the
curved surface or groove on the block c will depend on the proportions between the
lengths of the connecting rod, levers ƒ and g and the stroke of the tool carriage h. It
will also be evident that the curve suitably shaped, might be formed on the end of the
projection a attached to the connecting rod, and act upon a straight lever g' (or
friction roller thereon) forming part of the bent lever carrying the tool e. The tools e
may be placed side by side or behind each other, (i.e. tandem fashion), and operated
singly or alternately.
C
Plate II Figs. 3 and 4, and Fig. 51Plate I illustrate the means, referred to in the
first part of our provisional specification, for facilitating the raising and lowering of
the table. Fig. 3 is a side elevation (with the turntable in section), and Fig. 4a plan
on line C. D. E. F. Fig. 3, of a machine for Setting, Striking, Slicking etc. with
these improvements attached thereto. This portion of our invention consists in the
use of wedges, which are moved simultaneously in and out in a radial or approxi-
mately radial direction, (i.e. to and from the centre of the turntable. The wedges i
(see also enlarged views Fig. 5 Plate I,) thus raise and lower simultaneously all the
bearings m; and along with them the table, keeping it all the time in a level position.
The inner ends of the wedges are attached to links or connecting rods o, the other
ends being passed over pins fixed to the centre plate p. This plate may be slightly
rotated by means of links and levers, or by toothed gearing, or as shewn in the
drawings Fig. 4, by means of hand wheel q and worm gearing r.
71
Lastly Fig. 3 Plate II and Figs. 67, and 8 Plate III illustrate the means we adopt
for automatically moving the bottom carriage backwards and forwards against the
tool. In Fig. 3 Plate II this is effected by means of a long screws running parallel
to the motion of the bottom carriage t. The screws is driven from the driving
shaft of the machine, and works in a nut v attached to the bottom carriage t. Tho
screws may be thrown into and out of gear with the driving shaft u by any suitable
mechanism; or the nut v may be opened and closed upon the scrow s, as is the case
with the nuts for the leading screws of lathes. In Fig. 6 this purpose is shewn
effected by means of a toothed wheel w on one of the axles of the bottom carriage;
such toothed wheel w being actuated by means of a worm a driven from the driving
shaft of the machine. Fig. 7 shews (for the same purpose) an arrangement of a
rack Y attached to the bottom carriage t, in conjunction with a toothed wheel driven
from the driving shaft u. As shown in Fig. 8, we may also automatically move the

page_text: bottom carriage by means of an endless rope or pitch chain a, working round a pulley
or wheel b on one of the axles of the bottom carriage t. The rope or chain a is driven
by passing it round a pulley on the driving shaft u.
Figs. 9 and 10 Plate IV illustrate one of our improved methods for raising and
lowering such tables as have combined horizontal motions, by means of levers. Fig. 9
is a plan shewing the arrangement of the levers, and Fig. 10 a sectional elevation.
In these Figs. the bearings m along with the turntable a are raised and lowered by
means of the hinged levers 6, operated by the cam or eccentric c¹ from a hand
wheel d¹. The came depresses the plate e, to which the inner ends of the levers ¹
are connected by the links f¹. On reversing the motion of the cam c¹, the table a¹
lowers by its own weight.
In Figs. 17 and 18 sheet. V we have shewn an arrangement of toggle levers, for
raising and lowering the bearings of the turntable. Fig. 17 is a side elevation, and
Fig. 18 a part end elevation of one of the roller bearings, with the toggle levers. In
these Figs. the lower links of the toggle levers g are shewn hinged to a fixed support,
whilst the upper links are attached to the bearing m. The toggle levers are operated
by means of the link and the connecting rod it. The rods of all the bearings are
operated simultaneously by the saine means as is shewn in Figs. 3 and 4 Sheet II, for
actuating the links or connecting rods o. The bearings m are arranged to rise and
fall in vertical slides j'.
It will be evident that with slight modifications the arrangements shewn in Figs. 9
and 10 Sheet IV, and Figs. 17 and 18 Sheet V, can be adapted for raising the
table a indirectly, by raising directly either the cross or main carriage.
In Sheet IV Fig. 11 is a cross section, and Fig. 12 an end elevation, shewing our
mode of raising the cross or main carriage by means of cams or eccentrics. In these
Figs. represents the cross carriage and one of the wheels carrying the same.
That portion m¹ of the axle on which the bearings of the cross carriage rests, is turned
eccentrically with respect to the rest of the axle m²; so that by partially rotating the
axle m², the carriage is raised or lowered. The partial rotation of the axle m² is
effected by means of the forked lever n³, nut o¹, and screw pl; the scrow shaft being
operated by a hand wheel placed on the outer end in a position readily accessible to
the workman. By providing suitable vertical guides, the eccentric m¹ may be replaced
by a cam.
By altering the dimensions of the various parts, Figs. 11 and 12 will ropresent the
same arrangements for raising the main carriage.
Figs. 13 to 16 Sheet V illustrate our improvements for raising and lowering such
tables, as have combined horizontal motions, by means of screws. Fig. 13 is an end
elevation, Fig. 14 a side elevation, and Fig. 15 a plan looking at the underside of one
of the roller bearings, and screw for actuating the same. In the Figures the bearing m
forms at its lower part a shaft q' terminating in a screw surface 1, 2, 3, 4. This rests
upon a corresponding screw surface 1, 5, 6, 4, attached to the pinion . The pinions
of all the roller bearings are actuated simultaneously by means of a common toothed
wheels Fig. 16, such wheels being actuated from a hand wheel placed in a con-
venient position for the workman. The transmission from the hand wheel may be
effected either by toothed gearing, or a worm. Instead of forming the shaft part of
the bearing g' with a screw surface on its under side, it may have ordinary screw
threads cut on the outside, working into a nut formed in or fixed to the pinion r.
The bearing m is kept from rotating when the pinion is moved, partly by the
pressure of the table on the rollers, and partly by means of fixed guides or slides as
shew at j Fig. 17 and 18.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed; we declare that what we claim is :-
1° The use of a projecting piece or wiper a attached to the connecting rod & in
conjunction with a suitably curved surface or groove, (attached to the levers for
carrying the tools,) for the purpose of actuating the tools in the manner herein set-

page_text: forth, and substantially as herein described and shewn in the accompanying drawings
Plate I Figs. 1 and 2.
2° The employment of wedges or inclined planes i, moveable in a radial or approxi-
mately. radial direction, for raising and lowering the tables of certain machines
employed in the manufacture of leather substantially as herein, set forth and as
illustrated in Plate II Figs. 3 and 4 af the accompanying drawings.
3° The means herein set forth and illustrated in Plate II Fig. 3 and Plate III
Figs. 6, 7 and 8 for automatically moving the bottom carriage t of certain machines
employed in the manufacture of leather, substantially as herein described and as shewn
in the drawings just referred to.
Claim 4° The use of screws, cams, or eccentrics and levers, for raising and lowering
such tables as have combined horizontal motions, arranged to raise either the table
alone, or also the cross and main carriages, substantially as above described and
illustrated in Figs. 9-12 Sheet IV, and Figs. 13-18 Sheet V of the accompanying
drawings.

DESCRIPTION OF DRAWINGS.
Plate I shews the mechanism, referred to in the third part of this specification, for
operating the tool from the connecting rod. Fig. 1 is a longitudinal section of the
tool carriage on line A B. Fig. 2 is an end view. The mechanism consists of a
projecting piece or wiper a attached to the connecting rod 6 of the machine. The
projecting piece a works in conjunction with a suitably curved surface or groove
formed preferably on a separate adjustable block c. The block c is áttached and
adjusted in position on the hinged lever d carrying the tool e. The drawing shews
the tool carriage provided with two tools e, so that the leather is acted upon during
both the forward and backward motion of the carriage. The exact shape of the
curved surface or groove on the block e will depend on the proportions between the
lengths of the connecting rod, levers fand g and the stroke of the tool carriage h. It
will also be evident that the curve suitably shaped, might be formed on the end of the
projection a attached to the connecting rod, and act upon a straight lever g' (or.
friction roller thereon) forming part of the bent lever carrying the tool e. The tools e
may be placed side by side or behind éach other, (i.e. tandem fashion), and operated
singly or alternately.

Figs. 9 and 10 Plate IV illustrate one of our improved methods for raising and
lowering such tables as have combined horizontal motions, by means of levers. Fig. 9.
is a plan shewing the arrangement of the levers, and Fig. 10 a sectional elevation.
In these Figs. the bearings m along with the turntable a¹ are raised and lowered by
means of the hinged levers b₁, operated by the cam or eccentric c¹ from a hand
wheel d. The cam c¹ depresses the plate el, to which the inner ends of the levers 61
are connected by the links f. On reversing the motion of the cam c¹, the table a¹
lowers by its own weight.
In Figs. 17 and 18 sheet V we have shewn an arrangement of toggle levers, for
raising and lowering the bearings of the turntable. Fig. 17 is a side elevation, and
Fig. 18 a part end elevation of one of the roller bearings, with the toggle levers. In
these Figs. the lower links of the toggle levers g' are shewn hinged to a fixed support,
whilst the upper links are attached to the bearing m. The toggle levers are operated
by means of the link h¹ and the connecting rod. The rods of all the bearings are
operated simultaneously by the same means as is shewn in Figs. 3 and 4 Sheet II; for
actuating the links or connecting rods o. The bearings m are arranged to rise and
fall in vertical slides j¹.
It will be evident that with slight modifications the arrangements shown in Figs. 9
and 10 Sheet IV, and Figs. 17 and 18 Sheet V, can be adapted for raising the.
table a indirectly, by raising directly either the cross or main carriage.
In Sheet IV Fig. 11 is a cross section, and Fig. 12 an end elevation, shewing our
mode of raising the cross or main carriage by means of cams or eccentrics. In these.
Figs: represents the cross carriage and 11 one of the wheels carrying the same.
That portion m of the axle on which the bearings of the cross carriage rests, is turned
eccentrically with respect to the rest of the axle m²; so that by partially rotating the
axle m³, the carriage is raised or lowered. The partial rotation of the axle mis

page_text: effected by means of the forked lever n', nut o¹, and screw pl; the screw shaft being
operated by a hand wheel placed on the outer end in a position readily accessible to
the workman. By providing suitable vertical guides, the eccentric m³ may be replaced
by a cam.
By altering the dimensions of the various parts, Figs. 11 and 12 will represent the
same arrangements for raising the main carriage.
Figs. 13 to 16 Sheet V illustrate our improvements for raising and lowering such
tables, as have combined horizontal motions, by means of screws. Fig. 13 is an end
elevation, Fig. 14 a side elevation, and Fig. 15 a plan looking at the underside of one
of the roller bearings, and screw for actuating the same. In the Figures the bearing m
forms at its lower part a shaft q' terminating in a screw surface 1, 2, 3, 4. This rests
upon a corresponding screw surface 1, 5, 6, 4, attached to the pinion ¹. The pinions
of all the roller bearings are actuated simultaneously by means of a common toothed
wheels Fig. 16, such wheel s¹ being actuated from a hand wheel placed in a con-
venient position for the workman. The transmission from the hand wheel may be
effected either by toothed gearing, or a worm. Instead of forming the shaft part of
the bearing with a screw surface on its under side, it may have ordinary screw
threads cut on the outside, working into a nut formed in or fixed to the pinion r¹.
The bearing m is kept from rotating when the pinion is moved, partly by the
pressure of the table on the rollers, and partly by means of fixed guides or slides as
shew at j Fig. 17 and 18.
We are aware that a patent now expired was granted to Thomas Haley, Sam Haley,
Sugden Haley, John Haley and William Paul the 5th May 1871, No. 1217.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed; we declare that what we claim is :-
1° The use of a projecting piece or wiper a attached to the connecting rod b in
conjunction with a suitably curved surface or groove, (attached to the lovers for
carrying the tools,) for the purpose of actuating the tools in the manner herein set-
forth, and substantially as herein described and shewn in the accompanying drawings
Plate I Figs. 1 and 2.
Claim 28 The use of screws, cams, or eccentrics and levers, for raising and lowering
such tables as have combined horizontal motions, arranged to raise either the table
alone, or also the cross and main carriages, substantially as above described and
illustrated in Figs. 9-12 Sheet IV, and Figs. 13-18 Sheet V of the accompanying
drawings.
