"IM-
PROVEMENTS IN MACHINES FOR WEIGHING, LIFTING, LOADING, AND SHOOTING
SACKS OF CORN, COAL, OR OTHER PRODUCE OR MERCHANDIZE."
According to my Invention the first part refers to the use of grooved standards
to a weighing machine in such manner that the scale or platform upon which the
sack or. other weight is hoisted descends independently upon the platform of the
weighing machine. To accomplish this I connect the standards above referred to
to the outer framing of the weighing machine, the grooves at the lower ends of
the standards being enlarged, so as to give sufficient room to ensure the independent
working of the scale or platform as it descends. A portion of the front flange of
the standards may by preference be cut away as high as the guides of the scale,
and moveable plates substituted, the guides of the scale being bevelled at their
upper ends so as to pass freely into the narrow part of the grooves when being
hoisted.
'
The second part of my Invention has reference to shooting sacks. For this
purpose I provide a sliding frame, the sides of which act as guides when traversing
the grooved standards. Near the top of the sliding frame a horizontal bar is fixed,
which carries a second frame or tipping rack, upon which the sack or other article
is placed, and which is capable of revolving or tipping on the horizontal bar,
which acts as a fulcrum. To the lower corners of the sliding frame I connect two
ropes or chains, which are again connected to the outer ends of the winding spindle.
It will thus be understood that when the sliding frame is wound up the tipping
rack with the sack or other article upon it has ample room to swing between the
ropes or chains and under the winding spindle instead of over it as hitherto. It
also dispenses with the necessity of guide pulleys at the top of the standards. To
facilitate the tipping of the rack a chain may be attached at its upper end, and
again connected to the cross bar or stay of the main framing of the machine,

venient position for loading on to the carts or waggons. For this purpose I provide
a plate or hood at the top of the tipping rack, and as the sack or other article is
tipped over it rests in an upright position upon the plate or hood. A swing foot
may also be hinged at the lower end of the tipping rack for the convenience of
loading.
Fourthly. To prevent the winding handle of the machine from causing accidents
when lowering the cage I provide a socket formed in the boss, from which the
handle may be instantly withdrawn when necessary; or the socket may by pre-
ference be formed on the handle. For holding the cage at any desired height I
provide a pawl in a suitable position for dropping into the teeth of the cog wheel
of the winding spindle. Connected or formed on the pawl is a brake, which
immediately comes into action when the handle of the pawl is lifted, and allows
the cage to be lowered down at the will of the operator. By this means the cog
wheel takes the place of the ordinary ratchet....To add to the portability of the
machine the foot or bow of the main frame is made to slide or spring into sockets
provided for that purpose at the lower ends of the standards, and which can be
instantly removed when required.
