of the Commissioners of Patents, with his Petition, on the 6th December
1864.
I, HENRY LAMPLUGH, of Driffield, in the County of York, Ironmonger, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN TRUCKS
OR CARTS FOR CARRYING AND ELEVATING SACKS OR OTHER HEAVY BODIES," to be as
follows:-
This Invention has for its object improvements in trucks, carts, or carriages
suitable for receiving, carrying, or removing sacks or bags, filled with grain,
flour, or other materials, and for elevating the same into a position for having
the contents discharged either into sacks or otherwise, or for transferring the
sack from its elevated position on the truck into a conveyance warehouse, or
other place, and trucks, carts, or carriages constructed according to my Invention
aro also suitable for carrying and elevating other heavy bodies into a position
for being readily transferred or delivered therefrom.
My improved sack, truck, cart, or carriage consists of a frame of suitable
strength of wood or iron mounted on wheels. On the inner side of this frame
grooves or guides are formed for the sides of the frame on which the sack or
other heavy body rests to slide in. The upper part of the truck frame is jointed
or moves on axes so as to partly tilt over, when the sack or other heavy body
has been raised upon the sliding frame to the desired elevation which is accom-
plished in the following manner :-At the back of the main framing of the truck
a roller is mounted so as to revolve in suitable bearings on each side; on the

page_text: axis of this roller a toothed wheel is fixed, to which motion is communicated
by means of a crank handle and toothed pinion fixed on another axis upon the
framing. One end of a chain or rope is attached to the lower end of the sliding
frame, and passes up over a pulley mounted on the upper end of the tilting
part of the truck frame, the other end of the chain being fastened to the roller
or barrel of the winch previously described. By this means a sack resting on
the sliding frame can be raised or wound up by the winch until the sliding
frame has passed into the grooves of the tilting part of the truck frame, its
further movement is then arrested by chains or stops which connect the two
frames together, and by continuing the movement of the winch the tilting and
sliding or lifting frame will be caused to tilt over gradually until the frame and
sack thereon is brought over to an angle with the mouth of the sack downwards
and in a convenient position for its contents to be discharged where required,
or transferred into another sack if desired, the mouth of which may be attached
to and be held open by a suitable contrivance or instument on the end of the
tilting frame. The movement of the tilting frame may be arrested and secured
in any desired position by means of a pall and ratchet, or by other mechanical
means,, and the sack or other heavy body may be transferred from the sliding
frame when elevated into a wagon or other conveyance or on to an elevated
floor or platform. Legs or supports may be jointed or otherwise attached to
the back of the truck frame, to support it firmly in position whilst the sack or
other heavy body is being elevated thereon, and means or apparatus for
locking or "scotching," the wheels of the truck may be applied thereto if
desired. To the front of the truck or sliding frame, suitable instruments or
apparatus may be applied for holding the mouth of the sack open whilst it is
being filled previous to being raised if required.
This improved truck, cart, or carriage may be employed for receiving and
lowering heavy bodies as may be required.
