JEAN BAPTISTE COUDOINT-GOUGEUL, Constructeur at Montmorillon, in the
Department of the Vienne, and Republic of France. "IMPROVEMENTS IN TRAVEL-
LING CRANES AND TROLLYS."
My improved trolly is moved by the aid of a crank turned by the workman
mounted upon it, and which gives the desired speed to the trolly either by an
endless or a band chain with their toothed wheels, or by a series of toothed gearing
driving the axle itself on a shaft having at one or both ends a pinion with one or
two wheels on the axle. By this means the workman draws the load to its desti-
nation. His power becomes facultative by the addition of the necessary toothed
gearing.
This mechanical trolly, the form of which may vary, is intended to receive a crane
of my Invention, or any other crane or load. It may be moved backwards and-
forwards instantaneously on a railway, and it is provided with a very rapidly
working stopping arrangement.
I will first describe the construction of the crane, with carriage, by reference to
Sheet II. of the accompanying two Sheets of Drawing.
H, carriage (in side view) upon which the hoisting gear is placed when it is to
travel.
C, pedestal resting on its base, and having on its upper face a circular groove or
recess, as shown by the dotted lines.
M, fixed or moveable pin or stud in the centre of the pedestal to receive the
piece B.

page_text: .
B, cap revolving horizontally upon the pedestal C. Set in the stud M this cap
has at its base a circular projection of a semi-spherical shape, taking into the groove
of the pedestal C.
Having at its two uprights an opening forming bearings, and receiving the
gudgeon N belonging to the oscillating forked piece A (see side view of the entire
arrangement, Figure 2.)
A, oscillating forked piece in front view, provided with all its accessories, its
gudgeon N, resting in the revolving cap B, permitting it to oscillate forward to
take the load and backward to carry it away.
D, balance beam; a piece of iron of indefinite length secured in the fork piece A
by two bolts R; the distance of this beam from the axle will depend, upon the load
to be moved and its distance. The shape of this balance beam may vary; there is
a hole at each end.
X, hook with swivel, which is to receive any suitable hooking on arrangeinent,
such as tongs or nippers, hooks, chains, or other at one of the ends of the beam.
J, swing bar with a hook at each end, in which is passed a ring carrying two
others, each holding upper ends of the tongs or nippers I; these tongs being sus-
pended are closed.
F, saddle having in front two superposed lugs, with a hole to receive the pin V,
and at the bottom a flange for fixing the bridle frame or stirrup which is to receive
the load; the arrangement for receiving the bridle frame or stirrup may vary at
will. The said saddle has an opening in the middle, so that it may slide on the
beam D, moving on its two friction rollers Q.
:
Z, pins passing through the saddle, with two flanged rollers running on the lever
to facilitate tlie travel of the saddle.
S, rods connecting the two pins Z to keep them from revolving, but I may make
them revolving spindles.
G, bridle frame or stirrup, open on its two lateral faces, fitting on to the saddle
by its flanges to receive the weight required to lift the merchandise or materials to
be loaded. This bridle frame or stirrup may be arranged in any other way, according
to the material used to give the weight, cast iron, sand, stones, &c.
T', friction' roller with flanges placed inside the forked piece A;' its spindle is in
the opening made in the two uprights of the forked piece, see Figure 2.
E, rack resting on the roller T', having at one end a hole, fitting between the two
superposed lugs of the saddle E held by the pin V.
T2, roller with pin turning between two brackets bolted to the end of the rack E;
this roller runs on the beam D to preserve the parallel between the beam and the
rack.
W, shaft of the pinion P and ratchet R, to which is applied the crank O, and
which gears with the rack E.
This shaft rests on its two bearings (see Figs. 1 and 2):
K, toothed pinion acting as ratchet wheel, keyed on shaft W.
L, pawls serving to keep the counterweight fixed accordingly as it may be
required to keep the load raised or lowered, the one or the other being geared with
the ratchet according to requirement.
Y, cap or cover of the bearings and its bolts.
,.stops placed between the teeth of the rack front and back at pleasure to
prevent the counterweight being advanced or retired more than is required to lift
the load. This system prevents any accident arising from the awkwardness or
carelessness of the man employed at the crank.
Ts, brackets bolted to the rack E, carrying the roller T2, descending low enough
on each side of the beam D to serve as guide to the rack.
J (Figure 2); swing bar in front view, having at each end the clips or tongs I;
the swing har is held in the middle by the socket of its hook.
O, crank. When the clips or tongs or any other means of suspension has hold
of the pièce or load to be raised it is only necessary to turn this crank to the right
to cause the counterweight saddle to recede from the centre until the weights
.

page_text: balance the balance beam is then pushed to the right or to the left until it reaches
the spot where the load is to be deposited; the crank is then turned to the left, the
weight of the saddle lessens as it nears the centre, the load becoming heavier lowers,
and only requires to be released from the hook:
P, pinion, which by means of the rack draws the saddle along to approach' or
recede from the centre.
• :
Q(Figure 3), inner friction rollers of the saddle running on the beam.
f(Figure 1), safety piece, the height of which may be regulated at pleasure, the
object of which is to prevent any too rapid movement given by the man at the
crank resulting in too great a jerk.
a, two forked supports bolted the one on the saddle F, the other at the end of
the rack E.
The two supports a have within them at the upper part a toothed wheel b, with
shaft c intended to receive the endless chain band, or other chain, belt, hemp, or
wire cord, &c.
These same supports a each have at their upper part a pin e intended to support
an iron plate or bar of suitable dimensions to carry the counterweight.
b, toothed wheel; c, shaft of the toothed wheel; d, endless chain; e, pins holding
the iron bar or plate h, upon which the counterweight slides.
1, key with a thin edge on one side in its entire length entering between two teeth
of the toothed wheel in an opening made for that purpose in the support placed on
the saddle to keep the counterweight immoveable where it has been placed by
turning the crank m.
i, counterweight having two hooks, the one in front, the other behind; one of
them is free to be lengthened or shortened by means of a nut to give the desired
tension to the chain.
This counterweight is intended to equipoise the saddle F and its entire load when
it is brought to the centre at its limit with the end of the lever and its clip or
tongs I without load, so that the workmen are not obliged to counterbalance by
their own weight in order to place the clip or tongs I on the piece or article to be
lifted.
When the weight to be lifted is caught by the clip or tongs it is only necessary
to bring back the counterweight I to the support of the saddle F; this counter-
weight then increases the weight added to the saddle to lift the article or load to
he removed
