Improvements in Travelling Carriages for Raising, Lowering, and
Traversing Loads.
I, JOSEPH TEMPERLEY, of Wray Lodge, Reigate, in the County of Surrey,
Shipowner, do hereby declare the nature of this invention to be as follows :-
My invention relates to the carriages which are arranged to travel along beams
or girders and which have mounted on them pullies or sheaves over which pass
ropes or chains for the purpose of raising or lowering loads. The chief object
which I have in view is to effect not only the raising and lowering of the load but
also the travel of the carriage along the beam or girder by the action of a single
rope or chain worked by a single winch. The beam or girder may be inclined in
one direction so that the carriage when free tends to run to the one end, or if it is
not so inclined or if it is oppositely inclined, I provide a weight with a rope or
chain passing over a pulley at the one end so as to draw the carriage to that end, the
working rope or chain being passed to the operating winch over a pulley at the
opposite end. I construct the carriage in the following manner. I provide two
side cheeks having wheels which run on the beam or girder, or on the lower
flanges on each side of the beam or girder, and to these cheeks I joint the body
of the carriage by trunnions so that it is free to swing laterally. On the central
boss through which passes the spindle of the sheave or pulley I mount a lever the
lower arm of which is forked in such a manner that, on raising the rope or chain
which carries the load, a ball or protuberance upon it engages in this fork and
moves the lever partly round so that its upper arm passes a detent and comes
against a stop. In this condition the hauling of the operating rope or chain merely
pulls the carriage to the one end of the beam or girder. When the carriage
reaches a stop or tappet near this end, the detent is moved so as to release the
lever, but at the same time the carriage is engaged by a pawl which prevents it
from moving, and then the load can be lowered. On again hauling up the rope or
chain, its ball or protuberance again engaging with the fork causes the lever to be
again held by the detent, but at the same time releases the pawl, and now the
carriage can be run to the other end of the beam or girder. Here it meets
another stop or tappet which releases the lever, allowing the load to be lowered
or to be hauled up, and which moves a catch to hold the carriage in position
until the ball or protuberance again engages the lever releasing the carriage,
which can then be hauled along the beam or girder. The lower arm of the
fork lever is made in the form of a segment, so that the fork can be adjusted
to various positions on it, to suit various inclinations of the beam or girder.

Improvements in Travelling Oarriages for Raising, Lowering, and
Traversing Loads.
I, JOSEPH TEMPERLEY, of Wray Lodge, Reigate, in the County of Surrey,
Shipowner, 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 relates to the carriages which are arranged to travel along beams

page_text: or girders and which have mounted on them pullies or sheaves over which pass
ropes or chains for the purpose of raising or lowering loads. The chief object
which I have in view is to effect not only the raising and lowering of the load
but also the, travel of the carriage along the beam or girder. by the action of
a single rope or chain worked by a single winch. The beam or girder may be
inclined in one direction so that the carriage when free tends to run to the one end, or
if it is not so inclined or if it is oppositely inclined, I provide a weight with a, rope or
chain passing over a pulley at the one end so as to draw the carriage to that end,
the working rope or chain being passed over a pulley at the opposite end to the
operating winch.
A convenient form of track for such a pulley carriage is a flanged girder, the
carriage having wheels which roll on the flanges of the girder. I shall therefore
describe a pulley carriage according to my invention arranged to run along such a
girder.
Referring to the accompanying drawings,
Fig. 1 is a side view, of the carriage in condition for raising or lowering, without
travelling.
Fig. 2 is a side elevation shewing the carriage in condition for travelling along
the track without raising or lowering the load.
Fig. 3 is a front elevation.
Fig. 4 is a plan the girder and wheels being removed to show the cams below.
Figs. 5 and 6 shew details.
Fig. 7 illustrates the application of the apparatus for loading or unloading at a
wharf.
F
In these figures similar letters denote like parts.
The upper part of the carriage consists of a frame having two side cheeks A A
with four wheels a to roll on the flanges of the girder B two on each side of its
web. To the frame A is jointed at c. c, the under frame of the carriage, having
two side cheeks C, C, between which is mounted the pulley D free to turn upon a
pin d on which is also mounted, free to turn, a lever frame having two side
cheeks EE between which passes the rope I carrying the load. The lower
part of the lever frame E is formed as a fork at e e. A pair of arms el el
projecting from E E have pivotted to them at e a pawl lever having a pair of long
arms between which the rope E passes and a pawl e' which can engage with one
or other of a set of ratchet teeth on a segment c' which is fixed between the
checks C C and which forms at its lower end at c² a rest for e¹ e¹. The cheeks E E
are connected by a bolt e in such a position that when the cheeks move round the
pin d this bolt can enter, the gab of a cam G pivotted on a bolt g between the
cheeks A A. Another cam, H is in like manner pivotted on a bolt between
the cheeks A A. The cam H is wider than G and has a groove to receive. G.
Both the cams G and H have curved slots through which passes a bolt I this bolt
also passing through horizontal slots in the side cheeks A A. The cam H. has also
a projecting horn which can engage in a notch h² or in a piece or pieces M_M
fixed where desired to the under side of the girder B, and in a groove. of. H is
pivotted a pawl having a heavy lower arm or a spring. The slots in the cams G
and Hhave portions at their lower ends radial. To the cheeks A A is attached a
rope or chain K which passes over a pulley at the extreme end of the track and
has attached to it a weight sufficient to draw the carriage and load to the right
when the rope F is slacked out. On this rope Fat any desired part of it is fixed
a block L. This apparatus works, in, the following. manner. When it is in the
condition shewn in Fig. 1 the horn of the cam H being engaged in the notch h³
or it might be in a notch h³ at another part of the girder, the carriage cannot move
because the bolt I is in the radial part of the slot of H preventing H, from turning
in, either direction so as to disengage itself from the notch or . The load can
then be lowered by slacking out the rope F or raised by hauling it by a winch or
otherwise. In raising the load, the rope F passes between the cheeks e, and if it
should fub against either of them it might tend. to raise them with. it. This is
TITA

page_text: prevented by the pawl et engaging with a tooth of c¹. When the load is so far
raised that the block L on the rope F comes up to the lever arms e, between which
the block cannot pass, it raises these arms throwing the pawl & away from the
teeth, of c and the block L still rising moves the lever frame E E round to the
position shewn in Fig. 2. During this movement the bolt e entering the gab of G
moves G partly round causing the bolt I to slide along the horizontal slots in A A
and so far along the slot of H that H can be turned by its horn disengaging
itself from the notch or h³, this movement of H moving the bolt I still further
along the horizontal slots of A A and along the slot of G to the terminal part
which is radial, G being thus held stationary and holding the lever frame E E in
the position shewn in Fig. 2. In this position the block L being over the forks e is
held stationary sustaining the load and now, being disengaged, the whole carriage
can be pulled to the left by hauling F, or allowed to. be drawn to the right on
slacking out F, the load being thus carried along without being raised or lowered.
While H moves round as above described to the position shewn in Fig. 2 its
pawl h is turned into the notch as shewn in Fig. but as that notch has its
right side slotted the pawl can pass through the slot when the carriage travels
to the right.
When however the carriage is pulled to the left, the pawl is turned over
into the position shewn in Fig. 2, and then when the carriage travels to the right
the pawl is stopped by a shoulder at b so that H is again turned to the position
shewn in Fig. 1 turning G so as to release e and thus allowing the lever frame
to be carried down by the block L when the rope F is slacked out. The carriage
now being held as before by the engagement of ' in the notch, the load can be
lowered, or the end of the rope F can be lowered to take up a load which can
be raised, the carriage remaining stationary until the block L again releases it
and is held stationary. Pieces M each having a notch h' and a shoulder 6 being
fixed to the girder B at various places, the operator can at any of these places
lock or release the carriage releasing or sustaining the load; he has only to haul
the carriage by F to the left until the end of the pawl h* passes the shoulder b,
then on slacking out F, when h' meets b the carriage will become locked and the
load released as in Fig. 1 and will so remain until the ascent of the block L again
releases the carriage and is itself held stationary. The cheeks C C of the lower
part of the carriage might be fixed to the cheeks A A of the upper part. I prefer
however to joint 'the two parts together by pivots c c so that there may be freedom
to swing without throwing the wheels a off the track.
As shewn in Fig. 7 the girder B is inclined so that when the rope F is slacked
out, the carriage can run by gravity to the right. A number of the pieces M are
shewn on the underside of the girder to allow of locking and unlocking as above
described in a number of different places. When an inclined girder is employed,
as shewn in Fig. 7, the vertical line of rope below the pulley, instead of being in
the direction shewn at F in Fig. 1, will take a direction relatively inclined as
indicated by the dotted line F, the angle made by F2 with F¹ being equal to the
inclination of the girder. It is therefore necessary to adjust the segment c¹ and
with it the lower frame E E to this condition. This is done by providing several
holes at to receive the bolts by which the segment c' is fixed to the cheeks C C.
Also to allow for the consequent change of position of E E several holes are
provided to receive the bolte according as the girder is less or more inclined to the
horizontal.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a pulley carriage travelling along an overhead track for the raising
lowering and traversing of loads, the combination of a block fixed on the hauling
rope a double lever frame pivotted on the pulley axis and carrying a cross bolt, a
cam having a gab to receive the said bolt and a curved slot, a second cam having

page_text: also a curved slot, a bolt engaged in both curved slots and in horizontal slots of the
carriage frame, a horn on the second cam and a pawl pivotted thereon, and a
stationary notched and shouldered piece presented to the horn and pawl arranged
and operating substantially as and for the purpose set forth.
2. In a travelling pulley carriage, in combination with a pair of cheeks between
which the pulley is mounted a toothed segment fixed to the said cheeks, a lever
frame pivotted on the pulley axis, a double pawl lever pivotted on the said frame
and ends of the frame shaped as a fork engaging over them a block on the hauling
rope, substantially as described.
3. The combination with a travelling pulley carriage of pulley carrying cheeks C,
having a series of holes c³ to receive bolts to fix to it the segment c', a cam G, and
a lever frame E having a series of holes for a bolt e to engage the cam, substantially
as described.
