Improved Machine for Raising, Lowering, Stacking, or Removing
Timber and other Objects.
We, HENRY KITCHING STONE, Clerk, and CECIL RICHARD STONE, Wood
Broker, both of 203 High Street Hull in the County of York, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved machine more particularly intended for
raising, lowering, stacking or removing timber of any kind, but which may also be .
used for raising, lowering &c. other objects.
The machine consists of two strong upright legs carried on wheels at the
lower end and hinge-jointed together at the upper end. The one (back) leg is
by preference in a vertical position and is made telescopic or otherwise so that
it can be lengthened or shortened, while the other (front) leg assumes a more or
less inclined position according to the height of the back leg. The front leg is
bowed out on the front side and is there provided with a series of wide rollers
carried between two cheeks over which rollers the timber or other objects slide
up or down as they are being raised or lowered.
An endless chain belt or rope extends along this leg passing round the barrel
or bollard of a winch at the lower end of the leg and round a second barrel or
bollard at the top. This chain belt carries one or more grabs or clamps to which
the timber &c. to be raised or lowered is attached, so that by working the winch by
hand or other power, the chain is made to travel and thus raises the timber to the
top of the legs by means of the grabs. These are so arranged in any suitable
known manner that as they pass over the upper bollard they are brought in contact
with a stop or other releasing device which causes them automatically to release
the timber, which then passes on to a shoot or trough, one end of which is pivotted
to the front leg, while the other is supported by a "horse"
or support that is
adjustable in height so as to give the shoot any desired amount of inclination.
The trough is provided with rollers on the bottom and on the sides, for facilitating
the passage of the timber &c. along the same; it may be jointed in its length so as
to be capable of delivering the timber in various directions.
In order to enable the timber to be readily removed at various points of the
trough to stacks &c. situate on either side thereof, we provide in the trough small
turn tables, arranged in recesses so as to be flush with the bottom, and mounted on
a spindle the lower end of which is carried in a socket connected to a lever so that
when it is desired to remove a plank or piece of timber from the trough at the
point where a turntable is situated, the plank is run on to the turntable, and this is
then raised by the lever, so as to raise the plank out of the trough, and the plank
and turntable are then turned to a position at a right or other angle to the trough
so that the plank can then be slid on to the stack &c.
In place of a shoot, a platform may be employed.
The machine when not in use can be folded together in a compact form and can
be placed on a small truck for convenience of transport from one part of the
timber yard to another.

Improved Machine for Raising, Lowering, Stacking, or Removing
Timber and other Objects.
We, HENRY KITCHING STONE, Clerk, and CECIL RICHARD STONE, Wood
Broker, both of 203 High Street, Hull, 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:
This invention relates to an unproved machine more particularly intended for
raising, lowering, stacking or removing timber of any kind, but which may also be
used for raising lowering &c. other objects.
The machine consists of two strong upright legs carried on wheels at the lower
end and hinge-jointed together at the upper end. The one (back) leg is by
preference in a vertical position and is made telescopic or otherwise so that it can
be lengthened or shortened, while the other (front) leg assumes a more or less
inclined position according to the height of the back leg.
The front leg is bowed out on the front side and is there provided with a series
of wide rollers carried between two cheeks, over which rollers the timber or other
objects slide up or down as they are being raised or lowered.
An endless chain belt or rope extends along this leg passing round the barrel or
bollard of a winch at the lower end of the leg and round a second barrel or bollard
at the top. This chain belt carries one or more grabs or clamps to which the
timber &c. to be raised or lowered is attached, so that by working the winch by
hand or other power the chain is made to travel and thus raises the timber to
the top of the legs by means of the grabs. These are so arranged in any
suitable known manner that as they pass over the upper bollard they are brought
in contact with a stop or other releasing device which causes them automatically
to release the timber, which then passes on to a shoot or trough, one end of which
is pivotted to the front leg, while the other is supported by a "horse or
support that is adjustable in height so as to give the shoot any desired amount of
inclination.
"
The trough is provided with rollers on the bottom and on the sides, for facilitating
the passage of the timber &c. along the same; it may be jointed in its length so us
to be capable of delivering the timber in various directions.
In order to enable the timber to be readily removed at various points of the
trough to stacks &c. situate on either side thereof, we provide in the trough small
turntables, arranged in recesses so as to be flush with the bottom, and mounted
on a spindle the lower end of which is carried in a socket connected to a lever,.
so that when it is desired to remove a plank or piece of timber from the trough
at the point where a turutable is situated the plank is run on to the turntable,
and this then raised by the lever, so as to raise the plank out of the trough, and
the plank and turntable are then turned to a position at a right angle or other
angle to the trough so that the plank can then be slid on to the stack &c.
In place of a shoot, a platform may be employed.
The machine when not in uso can be folded together in a compact form and can
be placed on a small truck for convenience of transport from one part of the
timber yard to another.
On the accompanying drawings is shewn the construction of our above described
raising, lowering and transporting apparatus which we prefer to employ.
Fig. 1 shews a side view of the complete apparatus when set up for use.
Fig. 2 shews a front view of the front leg.
Fig. 3.a front view of the back leg and
Fig. 4 is a front view of the horse for supporting the trough.

page_text: Fig. 18 B view of the apparatus folded together.
Figs. 7 to 12 shew enlarged details.
The front leg is constructed of two bowed side frames A A suitably connected
together at the straight inner sides a, the bowed outer sides a' having a clear
space left between them all the way up.
The lower end is supported on wheels B and carries a winch C, with pitch
wheels or toothed bollards C' round which pass two endless pitch chains D that
pass round other toothed bollards C at the upper end, which chains travel upon
small rollers projecting from the inner sides of the beams a' a'. These two chains
are connected together at intervals by transverse plates E carrying spikes E',
which serve to seize a plauk of timber as they pass round the bottom bollard, as
indicated in dotted lines at X Fig. 1, and in travelling upward with the chains,
carry the plank up with them, as indicated at X' in full lines. Secondly the two
chains are connected at intermediate points between the plates E, by other plates F
which carry the grabs G for securely holding the planks as they travel upward
and which are by preference constructed as shewn in Figs. 7 to 9; Fig. 7 shews
a front view of the grab, Fig. 8 a side view and Fig. 9 a perspective view. Below
the plato F is a second plate H which is connected to the plate F by means of a
lever I, pivotted to H at H' and to Fat F¹ and carrying a heavy weight J at its
free end.
On the ends of H are fixed two strong cylindrical metal uprights K that pass
free through circular holes F in the plate F. These uprights are formed with
a shoulder at a certain height above F, and the reduced upper part K'is formed
with a sorew thread, on which is sorewed a nut L. Upon this nut rests a plate M
passed with a hole loosely over K'.
This plate is made of the segmental shape with rounded front side shewn at
Fig. 9 and it has its outer end supported by a curved stay M' fitting with an eye
loosely over the upper end of k', which carries a screw nut N above it.
On the outer side of the plate M is fixed or formed an upright segmental
piece M2 and other curved bars M3 M4 M5 extend from M to M.
The uprights K with their plates M form the grab for holding the plank tightly
between them and the plate F, and their action is as follows.
By the connection of the weighted lever I to the plates F and H it will be seen
that the weight tends to draw plate II and uprights K downwards, thereby
bringing the plates M towards F, so that if a piece of timber ✗ is inserted
between M and F, the weight J will cause it to be nipped between the two with a
force proportionate to the weight J and the leverage of I.
When however the grab has passed round the lower bollards C₁ the lever I with
its weight are caused to pass into a trough shaped guide O fixed between the
beams a' at the lower end, and extending up a certain distance as shewn in the
section at Fig. 5.
This guide supports the weight and lover while they slide up in it, in a raised
position relatively to F, so that H, K and M are also in a raised position and M
can turn readily upon K, being however lightly held in the position shewn by
suitable springs P.
By the time the grab has risen to the position shewn at G₁ Fig. 1 the plank will
be resting with its upper end against the rounded surfaces presented by the plates M
and bars M &c. so that the pressure exerted upon these by the plank will cause
them to yield, turning inwards into the dotted position Fig. 9, whereupon the
plank will fall flat on to the plate F. The plates M being now freed from the
pressure, will be drawn by the springs P back into their original position extending
over the plank.
By the time this has taken place the grab will have risen so far that the weighted
lever I J passes out of the guide O whereupon the weight in falling away from F
will pull down the uprights K and plates M and cause the latter to clamp the
plank tightly as described.
The grab with the plank will then rise up with the chains until the latter turn

page_text: round the upper bollards in order to descend again, and as they carry the grab
with them while the plank passes on to the trough Q, the plates M will again turn
on K yielding to the lateral pressure of the plank and will thus enable the grab to
descend clear of the plank.
In order to adjust the grab for different thicknesses of planks the clamping
plates M are shifted up or down upon the uprights K' by means of the screw
nuts LK.
The leg A is pivotted by brackets A' to the upper end of the back leg R R' this
is carried on wheels S at bottom and consists of a lower frame R and an upper
one R' that can slide up and down between guides on R, and is raised and lowered
by any suitable means, such as by ropes or chains T passing up from a winch T"
over pullies T on the upper end of Rand attached to the lower end of R'.
The leg R R is stayed from the leg A. by means of stay rods U, pivotted at the
lower end to R while at the upper end they are connected by an eye and bolt to
one or other of the eyes a³ on the undersides of the beam a, according as, by the
raising or lowering of the part R, the leg A is made to stand at a greater or
smaller angle to R R'. The trough Q with rollers Q is supported at its one end
by the leg. R R and at the other end by an adjustable horse V of known
construction, the height of which can be varied according to the height of RR.
From the trough Q the planks are delivered on to troughs on ways W with
rollers W, such as shewn in plan at Fig. 10. which may be arranged to branch off
in various directions for stacking the planks.
In these troughs are provided wherever required turntables for turning the
planks round corners or curves, and in places where there would not be room to
turn the planks on a turntable at the level of the trough, we construct the same so
as to be capable of being raised up out of the trough, as indicated at Figs. 11
and 12, in which the turntable Y is mounted upon a vertical axis Y which can be
raised and lowered in guides fixed to the trough and which is actuated by a
lever Z so that when it is required to turn the plank X at a sharp angle the
turntable is raised up with the plank into the position shewn at Fig. 12 and is then
turned round after which the turntable is lowered again. The turntable is by
preference provided with a suitable grab of any known construction for holding
the plank while it is being raised and turned.
It will be evident that the herein described apparatus although only described
for effecting the raising operation for stacking, is equally applicable for lowering
the timber from the stacks, for which purpose any other suitable arrangement of
grab for holding the planks on the chains would be employed..
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. A machine for raising, lowering, stacking or removing timber and other
objects consisting of a pair of lege A, R R pivotted together at top and carried on
wheels at the bottom, the leg R R being capable of having its height varied,
while the leg A carries endless travelling bands, chains or cords on which are fixed
at intervals spikes for seizing the timber and clamps or grabs for holding it
securely while being carried upward by the endless chains, substantially as
described.
2. In combination with a raising and lowering machine such as is referred to in
the preceding claim, the use of a clamping device or grab constructed and operating
substantially as herein described with reference to the drawings, whereby the timber.
or other objects are automatically clamped to the endless travelling chains so as
to be carried up thereby, and are automatically released when they arrive at
the top.
3. In combination with a raising and lowering machine such as is referred to in
the preceding claim, the use of a trough Q and horse V for conveying the timber
or other objects on to or from the stacks, substantially as described,

page_text: 4. The use in combination with the troughs or ways W for conveying timber to
or from the stacks of a turntable Y carried by a sliding vertical axis Y' and
operated by a lever Z for raising the timber to a certain level above the trough for
enabling it to be turned through any desired angle, substantially as desoribed.
