UNITED STATES PATENT OFFICEo
GEORGE VW. ROBBURTS, OF ELMO, TEXAS, ASSIGNOR OF ONE-IIALF TO
JOHN E. POLK, OF SAME PLACE.
TRACK-RAISER.
EPECIFICATION frming part of Letters Patent No. 336,161, dated Fereary 16, 1886.
Application filed Angust 4, 1885. Serial Ko. 173,577. (No molel.)fTo all whon it 7may co7cerl:
Be it known that I, GEORGE TW. ROBBURTS,
a citizen of the United States, residing at El-
mo, in the county of Kaufman and State of
5 Texas, have invented a new and useful Im-
provenient in Track-Raisers, of which the fol-
lowing is a specification, reference being had
to the accompanying drawings.
My invention relates to an improvement in
io railroad-track raisers; and it consists in the
peculiar construction and combination of de-
vices that will be more fully set forth herein-
after, and particularly pointed out in the
claims.
i5 In the accompanying drawings, Figure 1 is
perspective view of a track-raiser embodying
iny invention. Fig. 2 is a side elevation
showing the track-raiser in one position in
solid lines and in another position in dotted
20o lines. Fig. 3 is a vertical sectional view of
the same. Fig. 4 is a modification, and Fig.
5 is a side elevation of a modification of my
invention adapted for use as abridge-raiser.
A represents a base, which is of a length
25 adapted to fit transversely between the rails
of a railway-track, and from near the ends of
which project the vertical standards B, which
are reduced at their upper ends, as at C. A
vertical standard, D, projects from the center
30 of the base A, and the upper end of this
standard is also reduced, as at E.
F represents a transverse beam, which is
provided with three mortises, through which
extend the reduced ends of the standards, the
35 beam F being thereby enabled to be moved
vertically on the standards, as will be very
readily understood. To the outer ends of the
beam F, on its under side, are bolted or other-
wise secured lugs D', and to the outer ends of
40 the base A, on its upper side, are secured
similar lugs, H.
I represents toggle-jointed levers, which are
fulcrumed to and are connected at their joints
by rods K, the inner ends of which are ful-
45 crumed to hand-levers L on opposite sides
diametrically of the fulcrum-point 31 of said
levers, where the levers are fulcrumed to the
central standard, D, on opposite sides thereof.
The hand-levers are adapted to move through
50 half a circle in opposite directions to each
other, and cause the toggle-levers to assumethe positions shown in Fig. 2, and thereby
raise and lower the beam F. To the ends of
the beam F, on opposite sides thereof, are
pivoted two pairs of hooks, 0, which depend 55
therefrom and are adapted to engage with the
under sides of the track or rail.
The operation of my invention will readily
be understood from the foregoing description,
taken in connection with and by reference to 60o
the accompanying drawings.
Fig. 4 shows a modified form of my inven-
tion, in which each lever is connected by a
rod, K', with only one of the toggle-jointed
levers. By this arrangement it will be seen 65
that the toggle-levers can be worked inde-
pendently of each other, one at a time or both
simultaneously, so as to raise only one end of
the beam F when it is desired to raise only
one side of the track, or both ends of the beam 70
at once when it is desired to raise both sides
of the track. I also contemplate dispensing
altogether with the connecting-rods K and the
standards D, and securing the lower ends of
the levers firmly to the toggle-levers just be- 75
low the joints thereof, which would enable
either or both ends of the beam F to be raised
or lower.
In Fig. 5 I show a modified form of my in-
vention, which is adapted for use as a bridge- 8o
raiser or for raising other extremely heavy
weights, wherein I lengthen the projecting
end of the standard D and provide it at its upper
end with a windlass or winch, P, to one end
of which is fixed a ratchet-wheel, R. 85
S represents a hand-lever, which is fulcrumed
to the standard D, and is provided with a
spring-actuated or gravity pawl, T, which en-
gages with the ratchet-teeth of the ratchet-
wheel, and thereby as the hand-lever is oscil- 90
lated imparts a rotary motion to the winch.
Ropes V have their ends connected to the
winch and to the outer ends of the levers L,
and thereby the rotation of the winch winds
the rope thereupon and raises the outer ends 95
of the levers L, and thereby raises the weight
suspended bythehooks. A gravity or spring-
actuated pawl, WV, also engages with the ratch-
et-wheel, as shown.
Having thus described my invention, I loo
claim-
