page_text: LETTERS PATENT to Gilbert Sinkwell and Edwin Henry Tooley, both
of Dunstable, in the County of Bedford, Engineers, for the In-
vention of "IMPROVEMENTS IN MACHINERY FOR ELEVATING, SHOOTING,
LOADING, AND UNLOADING SACKS WHEN FILLED WITH CORN, PRODUCE, OR
OTHER MERCHANDIZE; ALSO APPLICABLE FOR OTHER HOISTING AND LOADING
PURPOSES.'
"
PROVISIONAL SPECIFICATION left by the said Gilbert Sinkwell and
Edwin Henry Tooley at the Office of the Commissioners of Patents,
with their Petition, on the 25th May 1875.
We, GILBERT SINKWELL and EDWIN HENRY TOOLEY, both of Dun-
stable, in the County of Bedford, Engineers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
ELEVATING, SHOOTING, LOADING, AND UNLOADING SACKS WHEN FILLED WITH CORN,
PRODUCE, OR OTHER MERCHANDISE; ALSO APPLICABLE FOR OTHER HOISTING AND
LOADING PURPOSES," to be as follows :—

page_text: machines for elevating, shooting, loading and unloading of movable
bearings which are free to travel in grooves provided for the purpose.
The movable bearings are connected to the spindle or cross bar which
carries the sack frame and move up and down therewith.
•
The grooves are preferably made of wrought channelled iron. The
top of frame carries pulleys round which cords or chains pass to the
movable bearings, and on the other side to a spindle carried by brackets
attached to the side frames of the machine. The spindle is driven by a
winch in the ordinary way.
The Invention further consists in the employment of an attachment:
to the frame of machines as aforesaid in such manner that the frame or
barrow for carrying the sack or other article is tilted when it arrives at
a given height. For this purpose we connect to the framework of the
machine by bolts and nuts, or by a thumbscrew or other suitable
appliance, certain guides or struts over which friction rollers on a 1
spindle connected to the carrying frame are free to travel. As the
frame with the sack on it is raised the rollers aforesaid come into action
travelling along the guides or struts; on arriving at the upper part
thereof the weight of the sack causes the frame to tilt over. There is a
spring which is attached to the guides or struts which hooks on to the 2
spindle of the carrier frame or on to a separate projecting piece which
comes into action and prevents the carrier from tilting too far over. As
soon as the sack leaves its frame the spring brings the frame back to
position ready to descend. There is a frame with hooks attached
projecting from the sack carrier to carry the empty sacks.
The whole machine is rendered portable by being mounted on wheels

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of May, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Gilbert Sinkwell and Edwin
Henry Tooley, Her special licenco that we, the said Gilbert Sinkwell
and Edwin Henry Tooley, our executors, administrators, and assigns,
or such others as we, the said Gilbert Sinkwell and Edwin Henry Tooley,
our executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN MACHINERY FOR ELEVATING, SHOOTING, LOADING, AND
UNLOADING SACKS WHEN FILLED WITH CORN, PRODUCE, OR OTHER MERCHANDISE;
ALSO APPLICABLE FOR OTHER HOISTING AND LOADING PURPOSES," upon the
condition (amongst others) that we, the said Gilbert Sinkwell and Edwin
Henry Tooley, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should
particularly describo and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Gibert Sinkwell and Edwin
Henry Tooley, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings and to the letters of reference
marked thereon, that is to say :—
The first part of our Invention consists in the application to machines
of the above description of moveable bearings which are free to travel in
grooves provided for the purpose. The said moveable bearings are
connected to the spindle or cross bar which carries the sack frame (or to
any convenient points on the sides of the same), and move up and down
therewith.
The grooves are preferably made of wrought channelled iron
and

page_text: the side frames of the machine are constructed of this material they in
themselves constitute grooves or channels for the reception of the
moveable bearings. At the top of the side frames are situated pulleys,
over or round which cords or chains are passed, having one end attached
to the moveable bearings, while the other is wound upon a spindle
carried in brackets attached to the side frames of the machino and
actuated by a handle in the ordinary manner.
The Invention further consists in the employment of certain guides or
struts attached to the frame of machines in such a manner that tho
sack frame is tilted when it arrives at a given height so as to deposit its
load, or "shoot" the contents of one sack into another.
The tilting action is accomplished by means of friction rollers upon
the sack frame which traverse the inclined guides or struts until the
sack frame and load are over balanced and caused to tilt over to tho
other side.
To prevent the sack frame from tilting too far a spring is provided
which hooks upon the roller or spindle of the carrier frame, or on to a
separate projecting piece; by this means the sack frame is arrested, and
upon the deposition of its load brought back to position ready to
descend:
In lieu of the guides or struts herein-before referred to, a chain or
cord may be employed to tilt the sack frame, such chain or cord being
of a suitable length, and attached at one end to the carrier frame, and
at the other to a fixed point, projection, or bracket from the side frames
of the machine.
To check the tilting action a similarly fixed chain or cord is arranged,
baving at either end or in its length the india-rubber, spiral, or other
suitable spring which is used in conjunction with the guides or struts.
When used for "shooting" purposes, that is to say, to pour or “shoot”
the contents of one sack into another, a light frame is employed and
mado so as to be casily attachable to and detachable from the sack
carrier. It is also provided with hooks which carry the empty sack.
The whole machine is rendered portable by being mounted on wheels
in the ordinary manner.

page_text: And in order that our said Invention may be more completely
understood we have hereunto appended a Sheet of Drawings illustrative
of the same, and which we will now proceed to describe, reference being
had to the letters and figures marked thereon, corresponding letters
indicating corresponding parts in all the views.

page_text: reached the top of the "struts" or guides N, as shewn in dotted lines,
the carrier frame I becomes over balanced by the weight of the sack
upon it, and tilts into the position indicated in dotted lines, in which
position it is held by the springs Q, the hooks of which catch the rollers,
or it may be any other suitably arranged projections upon the frame I
so as to arrest the tilting action. The recoil of the springs Q draws the
frame I back into position to descend after it has doposited its load in,
say, the position marked x.
Figure 2 shows a modified arrangement, whereby the herein-before
referred to guides or struts N are dispensed with, and for them are
substituted the chains O and P, the chain O performing the tilting
action while the chain P with the spring Q' attached serves to arrest the
frame I at the proper point. The operation of this arrangement is as
follows: The sack having been placed upon the frame I, it is hoisted
by the herein-before described means until the ascent of the upper part
of the frame I is checked by the chain O (the lower end of which is
attached to a projection on the stay c) becoming taut. The hoisting
action being continued, the carrier frame begins to tilt upward until it
assumes the position shown in dotted lines, whereby the load is discharged
and the carrier frame left free to descend. The india-rubber or spiral
springs Q' forming part of the attachments P, become of special value
when the apparatus is applied to "shooting" or transferring the contents
of one sack to another, as illustrated at Figure 3; in this case a light
frame R shewn separately at Figures 9 and 10 is attached to the carrier
framo I, such attachment being readily and securely effected by simply
springing inwards the sides of the frame R, so as to slip the projections S
on the frame I into the eyes formed to receive them in the frame R.
To make it perfectly firm, the frame R also rests at the hooked part
on a cross bar of the frame I, by which it is held immoveably in
position whatever angle the frame I may assume. The empty sack is
placed or hung upon the hooks of the frame R, and when full it is
merely necessary slightly to depress the frames I and R in order to
disengage the hooks from the mouth of the full sack, in order that
it may be replaced by an empty one. The spring Q' on the attach-
ment P permits of this depression of the frames I and R, or when the
frame R is applied to the apparatus shewn at Figure 1 the springs Q
serve the samo purpose.

page_text: Thus our Invention as herein-before described may be employed for
three distinct purposes,—
Firstly. To elevate.
Secondly. To load or unload, as for example, into or from a cart or
5 other vehicle.
And, Thirdly. To "shoot" or transfer the contents of one sack into
another, or into any suitable receptacle,
Having now described our said Invention and the mode or manner in
which the same may be carried into effect, we would observe in con-
clusion that what we consider to be novel and original, and therefore
claim as the Invention secured to us by these Letters Patent is,―
.
Firstly. The moveable bearings K sliding upwards and downwards in
grooves provided for that purpose, and upon which the sack or carrier
frame is suspended or centred, substantially as herein-before described
and shewn.
Secondly. The employment of a sack or carrier frame of the con-
struction or configuration herein-before described and shewn suspended
upon moveable bearings provided with friction rollers, and capable of
being canted or tilted, substantially as and by the means described.
Thirdly. The inclined, or curved guides, or "struts" N, and springs Q.
Fourthly. The means of canting or tilting the sack or carrier frame
described and shewn at Figures 2, 3, and 4, consisting of the attach-
ments O and P, the latter being provided with india-rubber, spiral, or
other suitable spring Q' to give elasticity to the checking attachment P,
and also to allow of further canting or tilting when it is desired to
disengage the hooks of the frame R from a full sack as herein-before
described.
Fifthly. The frame R provided with hooks, and capable of being
readily attached to and detached from the sack or carrier frame I by
being sprung into position.
Sixthly. Constructing the side frame A of wrought channelled inn af

page_text: parts constituting our improved sack lifter, shooter, and loader, sub-
stantially as described and shewn.
In witness whereof, we, the said Gilbert Sinkwell and Edwin Henry
Tooley, have hereunto set our hands and seals, the Sixteenth day
of November, in the year of our Lord One thousand eight 6
hundred and seventy-five.
