DI BUTICATION.
A New or Improved Spanner.
I, GEORGE FRANCIS LA CLOCHE, Rentier, of 21 Beau Rivage, St. Clements,
Jersey, Channel Islands, 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:-
This invention consists of a new or improved spanner, so arranged that the jaws
may be reversed as required, and the same is carried out as follows, reference being
had to the annexed drawings, in which Figure 1 is a side elevation of my spanner.
Figure 2. elevation of moving jaw.
Figure 3. longitudinal section of nut.
Figure 4. end view of same.
Figure 5. perspective view of handle of fixed jaw.
A forms the top piece or grip, B the body or handle, C the regulating screw.
The whole is made of wrought steel or the like.
Description of part A: The part a b is oblong in shape and measures 12 inches
leng 11/24 inch broad, inch thick.
The part b c which forms the screw is 15/12 inches long 7/24 inch diameter
and has a fine screw thread running to within of an inch from the end. This
screw thread is filed flat on two sides (the top and underside) the end is made to
form a small screw driver. dd & e form the top grips for nuts, is less thick at d
than at e and is formed as shewn in drawing the part d having a smaller slit than e
to fit small and large hexagon nuts respectively.
The part B is solid from a to b except that it has an opening at d to allow of
the screw nut C entering to pass on the screw thread of A. The part marked e¹
is flat and has a slit f as shewn in drawing, which with the slit é in A forms a
grip for hexagon nuts.
The part C is inch long and inch diameter and has a screw thread running
its entire length, such thread made to work with the thread on A. Two sides
of C are filed flat outside, and inside the thread is also filed away on the opposite
sides, which makes the hole more of an oval than a round in such a way that if
the flattened surface of C be turned parallel with the front surface of B, A can be
withdrawn away and by a half turn of C it grips the screw thread of A and so
is regulated in the shortest time to any nut, and in short owing to the formation
of the spanner it can be fitted to any square nut not larger than one inch sides and
any hexagon nut not larger than 1 inch across when the two large slits of A
and B are facing.
When A is reversed so that the small slit faces the large slit in B it forms a
secure grip for small hexagon nuts which would not be gripped by the larger
openings.
Having now particularly described and ascertained the nature of my said inven-
ion, and in what manner the same is to be performed, I declare that what I
laim is
1. The combined construction and arrangement of the various parts substantially

page_text: 2. In spanners of the class herein described; a movable gripping jaw having
two operating surfaces so arranged that for operating surfaces may be used in
conjunction with an operating surface upon the handle or body of the spanner,
said operating surfaces being provided with suitable recesses or notches engaging
upon the nut or the like to be turned. A screw thread formed upon the shank
carrying the movable jaws and of a cross section so as to correspond with the screw
nut so that when the shank is turned into a certain position it is free to pass
through the screw nut aforesaid which is recessed for the passage of the thread,
and in another position the screw. thread will engage upon the thread on the nut
so as to enable the movable jaw to be freely adjusted to the thread of the nut to
be turned and then by a partial rotation of the screw.nut aforesaid to be secured in
the required position; end of said shank being formed so as to act as a screw travel
when required.
