PROVISIONAL SPECIFICATION
A New and Simple Method for Working the Three Motions
Required to an Overhead Travelling Crane Driven Directly
off Shaft.
EDWIN WADDINGTON 14 Warwick Street Barrow in Furness Lancashire Mechanical
Engineer do hereby declare the nature of this invention to be as follows:-
For working the three motions required to an overhead travelling crane driven
directly off shaft running the full length of gantry the full distance the crane is
required to travel.
The three motions mentioned above are
1st. For hoisting and lowering.
"
2nd. cross travelling either way.
3rd. travelling lengthwise do. do.
The arrangement to be as follows:
"
Three friction clutches or catch boxes marked on plan 1. 2. 3. on end of crane with
the main driving-shaft D passing through them. Each of these clutches or catch
boxes gives motion to a pair of mitre wheels E E which run loose over main driving
shaft and gear into mitre wheel F which is keyed on the end of shaft A at right
angles to D so that when the clutches or catch box 1 is moved from one mitre
wheel E to the other mitre wheel E the motion of cross shaft A is reversed. This
description applies to the three motions as follows:-
Clutch 1 gives motion to shaft A both ways for hoisting & lowering.
Clutch gives motion to shaft B both ways for cross traversing either way.
Clutch 3 gives motion to shaft C for lengthway traversing either direction.
Each of these motions can be worked separately any two together or conjointly by
a person on stage G which is suspended under the end of cross girders H. H where
he can easily manipulate each motion as required by means of three hand wheels I. J
& K connected respectively with clutches 1. 2. & 3.
The feature of novelty is the arrangement of clutches or catch boxes fixed on the
end of crane either on or parallel to the main driving shaft D which drive the three
motions independently direct from the said shaft.

1 EDWIN WADDINGTON Mechanical Engineer of 14 Warwick Street Barrow in
Furness Lancashire do hereby declare the nature of this invention and in what
manner the sanie is to be performed, to be particularly described and ascertained
in and by the following statement :-
-
The three weanicita mations given to the book of a travelling crane are

page_text: mitre wheel E to the other mitre wheel E & by this meaus the motion of cross shaft A
is reversed.
This description applies to each of the three clutches 1. 2. & 3.
Clutch 1 gives motion to shaft A for hoisting & lowering.
Clutch 2. gives motion to shaft B for cross traversing either way.
Clutch 3 gives motion to shaft C for lengthway traversing in either direction.
Each of these motions can be worked separately any two together or conjointly
by a person on a stage suspended under the end of cross girders H. H. where he can
easily manipulate each motion as required by means of hand wheels I. J. K. connected
respectively with clutches 1. 2. & 3.
Having now particularly described & ascertained the nature of my said Inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
The arrangement of three (or more) clutches or catch boxes (fixed on the end of
crane either on or parallel to the main driving shaft D) which drive respectively the
three motions required, direct from the said shaft.
The above letters refer to drawings with Provisional Specification.
