Improvements in Stacking Derricks.
We ABRAM GALLAGHER of Mode in the County of Shelby, and State of Illinois,
and JOHN SNYDER BURK of Shumway, Effingham County, Illinois, and SILAS
RAGAN, of Fancher, Shelby County, Illinois, NEWTON GALLAGHER of Fancher,
Shelby County, Illinois, and WINFIELD LANTZ of Fancher, Shelby County, Illinois,
and HENRY GALLAGHER, of Fancher, Illinois, all of the United States of America,
Farmers, 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:-
My invention has relation to stacking derricks; and it consists in the improved
construction and combination of parts, as will be hereinafter fully described, and
pointed out in the claims.
In the accompanying drawing letters are used to indicate the several parts, A repre-
senting the runners of the sled ; B, the benches; C, the X-shaped trusses, the front
upper prongs of which are longer than the rear ones; D, braces from the front part of
the trusses to the front runner of the sled ; E, stays from the back part of the trusses
to said runner; F, top rails, one extending in an inclined manner across the upper
end of each truss and projecting from the front thereof, the middle rail projecting
the farthest, G, braces from said rails to said trusses; H, a tie-beam at the back
ends of said rails; I, a beam connected to the under sides of the front ends of
said rails, which while it acts as a tie-beam, also forms a runway for a hay
elevator, or serves as a means for attachment of such runway; J, a yard binged
to the middle top rail, to be used as a runway or serve as a means for attachment
of one K, links for supporting the outer end and middle of said yard;
L, guys attached to the rear upper corners of the derrick M, a rope for running
the elevator when a stack is to be formed, and N, one for running the elevator
when a rick is to be formed.
The runners are provided at each end with means for hitching alteam to them
for the purpose of hauling the derrick from place to place.
When a stack is to be formed, the elevator is attached to the yard while in
the position represented in full lines, the rope M, passing from the elevator, which

page_text: is lowered from the outer end of the yard, back over the derrick, down through
a pulley, O, secured to the ground, and then to the horse or other means used
for running said elevator.
When the derrick is to be used in forming a rick, the links are detached from
the yard and the latter swung down and secured to the truss, out of the way of
the elevator. (See dotted position of said yard.) Then the rope N, is passed
from the elevator, which is lowered from one end of the front tie beam, along
under said beam to its opposite end, there through direction changing pulleys back
over the derrick, down through a pulley, P, secured to the ground, and then to
the means employed in running the elevator.
If it is desired to use the derrick wholly for stacking, the end trusses with their braces
and stays and the tie beams may be dispensed with. On the other hand, if the derrick
is to be used exclusively for building ricks, the yard and its links may be dispensed
with and the middle rail made no longer than the end ones; or the end ones may be
made as long as the middle one, and the projecting end of each provided with an
eyebolt or a hook, (see dotted lines) to which a pulley may be attached, and the simple
horse fork and rope used on first one rail, and then another, till the rick is finished.
By passing the hoisting ropes back over the derrick to pulleys secured to the
ground, the necessity of staking the derrick to the ground is obviated, since by such
arrangement the weight of the load on the elevator is borne equally by the opposite
sides of the derrick. The guys shown are merely to keep the apparatus from blowing
over when not in use.
A stacking or ricking derrick constructed as herein described is light, strong,
durable, and easily moved about. This last feature is a most important one, since
thro' it much time is saved which has heretofore been spent in handling derricks that
must be taken to pieces every time they are moved.
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. In a stacking derrick, the combination of a sled, X shaped trusses-having one
upper prong of each longer than the other, braces and stays from said trusses to said
sled, top rails, braces from said rails to said trusses, a tie-beam across one end of said
rails and adapted to act as or form a means of attachment for a runway, and means
for operating an elevator upon said runway.
2. In a stacking derrick, the combination of a sled, X shaped trusses, braces and
stays, inclined top rails, the middle one of which is longer than the others, a yard
hinged and linked to said rail and adapted to act as or form a means of attachment for
a runway, and means for operating an elevator upon said runway.
3. In a stacking derrick, the combination of a sled, an X shaped truss, braces and
stays from said truss to said sled, an inclined top rail, a yard secured in a horizontal
position to said rail and adapted to act as a runway, and means for operating an
elevator upon said runway.
4. In a stacking derrick, the combination of a sled, X shaped trusses, braces from
one of the runners of said sled to the front part of said trusses, stays from said runner
to the back part of said trusses, top rails projecting beyond the front prongs of said
trusses, braces from said rails to the trusses, hooks secured to the projecting ends of
said rails, tie beams guys and means for operating a horse fork from each of said hooks.
