JGNACIO ARCOS, OF SAN ANTONIO, TEXAS.
IMPROVEMENT IN SCRAPERS.
Specificnition forming prt of Letters Patent No. 152,060, dated lone 16, 1874; application filed
May 15, 1874.'o all vlwhom it iuety co-ncern: [
Be it known that I, ItNxAco ARCos, of San
Antonio, 13exar county, State of Texas, have
invented a new and useful Improvement in
Excavators; and I do hereby declare that the
following is a full, clear, and exact description
of the same, reference being had to thle accom-
panying drawing forming a part of this speci-
Tication, in which-
Figure 1 is a plan view of excavator; Fig.
2, a vertical side elevation.
This invention relates to that class of ex-
cavators in which a large heavy scoop is at-
tached to a gearing of wheels to be drawn by
horses. Its object is to facilitate the process
of digging or filling up ditches, leveling roads
or fields, grading of railroads, c.; and it con-
sists of a heavy scoop having a rod running
along the upper edges of its sides, with loops
in both ends to form an adjustable support.
To the rings in these rods are attached the
chains that support the scoop, the other ends
of which are attached to the elevated horizon-
tal part of the crank-axle. To the vertical
parts of the crank-axle are attached the lever-
arms,which may be raised or lowered by ropes
attached to their ends, passing around pulleys
or sheaves in the shafts, and wound around a
windlass having a ratchet-wheel and pawl, by
means of which arrangement the scoop may
be raised or lowered.
In the drawing, A represents the scoop, hav-
ing partition or brace a, rods B, with loops b
b', handles a', adjustable link c, and chains c'.
C represents the wheels that revolve upon the
axle D, and E the lever-anms that are attached
to the crank-axle by braces 4 d'. To the ends
of these arms are attached the ropes d",which
pass around the sheaves e, and are wonund
around the windlass F by the crank e', the
ratchet-wheelsf and pawlsf' serving to keep
the arms E in place. Upon a cross-bar, G,
that is placed across the shafts IT, is erected
a vertical frame-work, I, in the top of whichis the pulley and crank g, connecting with the
pulley on the windless iS by a chain or cord,
g', by means of which arrangement the scoop
may be raised or lowered by the driver, who
is supposed to stand on the platform J. To
the frame I is adjusted another crank, h, hav-
ing a bell-crank,h', below, connected with the
pawls f' by rods i.
To operate this scoop, unwind the windlass
and allow the scoop to fall upon the ground
by letting the arnus E go back. Sow place
the rings of the clhain o' in the front loop b of
rods B, and, by elevating the handles (' of
scoop and driving forward the machine, the
scoop is filled. Now back the wheels, and
place the rings of chain o' in loops b'. Then
attach the a:ijstable link c, one end to the
back of the scoop and the other to the crank-
axle, andl wind up the windlass, which, by
drawing down the arias EI, brings tlle scoop
in a suspended position directly beneath the
axle, ready for transportation.
Having thus described my invention, what
I claim as new is-
1. The rods B, witil loops b b', brace a, and
adjustable link c, in combination with scoop
A and handles o', as and for the purpose de-
scribed.
2. The 'ever-arms E, as attached by braces
d d' to crank-axle 1), in combination with ropes
d", sheaves e, windlass F, crank e', ratchets f;
and pawls f', as and for the purpose specified.
3. The frame I, with crank and palleyg and
chain g', in combination with the windlass F,
rods i, bell-crank W', shaft and crank h, and
platform J, as and for the purpose described.
4. The rods B, with loops b b', brace a, and
adjustable link c, in combination with chains
c', crank-axle 1), braces d ci', and lever-arms
E, as and for the purpose specified.
