IMPROVEMENTS IN SPANNERS
Year: 1884

page_text: I, PERCY JOHN WATES of Norfolk Lodge, Tulse Hill in the County of Surrey,
Civil Engineer do hereby declare the nature of my invention for "IMPROVEMENTS
IN SPANNERS" to be as follows:-
This Invention has for its object the construction of a spanner adapted to nuts
and bolts of many sizes..
The spanner consists of two principal parts and a pin to hold them in position.
The first part is that containing the jaws which is by preference made circular
and is called the disc or head of the spanner; around its periphery are cut jaws of
various sizes and it may be made with a square central hole to keep it in position
in the handle or lever, or with a boss on one side in which may be cut a dovetail
groove or radial wedge shaped grooves to receive the lever or handle. When the
dovetailed groove is used, a small pin is dropped through the lever in the disc to
prevent them falling apart, but, when the wedge shaped radial grooves are used, a
central bolt is put in from the under side of the disc, the head being flush therewith
and the lever is held into the radial grooves by a wing nut.

The second part consists of the lever, which is made to correspond to and fit
the disc.
Where the nuts to be moved by it are not surrounded by a surface immediately
under the nut, a jawed lever and the square central pin may be used; but, when
the surface does occur, the other forms described are preferred.

I PERCY JOHN WATES of Norfolk Lodge Tulse Hill in the County of Surrey
Civil Engineer do hereby declare the nature of my invention for "IMPROVEMENTS
IN SPANNERS" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention has for its object the construction of a spanner adapted to nuts
and bolts of many sizes.
The spanner consists of two principal parts and a pin to hold them in position.
The first part is that containing the jaws which is by preference made circular
and is called the disc or head of the spanner; around its periphery are cut jaws of
various sizes and it may be made with a square central hole to keep it in position
in the handle or lever or with a boss on one side in which may be cut a dovetail
groove or radial wedge shaped grooves to receive the lever or handle. When the
dovetailed groove is used a small pin is dropped through the lever in the disc to
prevent them falling apart, but when the wedge-shaped radial grooves are used a
central bolt is put in from the under side of the disc, the head being flush therewith
and the lever is held into the radial grooves by a wing nut.
The second part consists of the lever which is made to correspond to and fit
the disc.
Where the nuts to be moved by it are not surrounded by a surface immediately
under the nut, a jawed lever and the square central pin may be used, but when the
surface does occur the other forms described are preferred.
In order that my said invention may be most fully understood and readily
carried into effect I will proceed to describe the Drawings hereunto annexed.
Figuro 1 is a side view of a spanner constructed in accordance with my 2
invention.
Figure 2 is an edge view.
Figures 3 and 4 show other discs for the same handle.
A is the disc containing jaws of various sizes as shown.
B is the handle, its upper end is forked as shown in Figure 2 so as to embrace 3
the disc A. The latter is adjusted and fixed in the handle by means of a square
pin C.
Figures 5, 6 and 7 show the handle of a modified instrument, and Figures 8 and 9
show a corresponding disc. As before A is the disc and B the handle; the latter
is provided with a dovetail D as shown, this fits into the dovetail groove E on the 3
disc.
The two parts are prevented from coming apart by means of a pin F
(Figure 10) The disc may if desired have two or more dovetail grooves instead of
one as shown,
Figures 11 and 12 are views of the handle of another modification and
Figures 13 and 14 are views of the corresponding disc. In this case the handle B 4
has wedge shaped projections G. G. upon it which enter into wedge shaped
grooves H in the disc. The parts are held together by means of a bolt and nut
shown at Figure 15.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
[ claim is
1. A spanner consisting of a handle and a head, the latter being removable from
the handle and provided with two or more jaws.
2. The spanner substantially as shown in Figures 1 to 4 of the Drawings.
3. The spanner substantially as shown in Figures 5 to 10 of the Drawings.
4. The spanner substantially as shown in Figures 11 to 15 of the Drawinga
Dated this 18th day of April 1885.
