Improvements in Spanners or Wrenches.
I JOHN WHITTIER THROOP of 15 Seething Lane London E.C. in the County
of London, Milling Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in spanners or wrenches and has for
object to facilitate the turning of the nut, stud or bolt in either direction and is
especially applicable for use in corners or cramped positions.
It consists of a handle or lever provided with an annular box shape recess at one
end within which is an inwardly projecting tooth or catch. One side of this
annular box is partly closed by means of a plate through the centre of which is an
opening, the other side being left open is partly closed by means of an annular
cover pivotted at one side to the handle and arranged to close against a stop or
shoulder formed upon the box.
Into this annular box a circular socket having a central opening corresponding
in size and shape to the nut or stud to be operated upon is loosely inserted, the
circumference of this socket being furnished with peripheral teeth arranged so as to
engage with the fixed tooth within the box.
In operation the action is as follows:-
A socket of suitable size and shape having been inserted within the annular box-
the pivotted cover is then closed over the same, and the central opening in the
socket slipped over the nut or stud to be turned. A circular or reciprocating
motion is then given to the handle or lever which causes the fixed tooth within the
annular box to engage with the peripheral teeth upon the socket and thereby cause
it to revolve, carrying with it the nut or stud to be turned. By reversing the
handle so as to present the opposite face of the socket to the nut or stud a reverse
motion can be imparted thereto. Spanners or wrenches thus constructed can be
used in the same way as an ordinary ratchet brace, any desired number of sockets
varying in size & shape can be used in turn and in the event of wear can readily be
replaced.

Improvements in Spanners or Wrenches.
I, JOHN WHITTIER THROOP of 15 Seething Lane London E.C. in the County
of London, Milling Engineer, 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 relates to improvements in spanners or wrenches and has for

page_text: object to facilitate the turning of the nut, stud or bolt in either direction and is
especially applicable for use in corners or cramped positions.
Upon the accompanying sheet of drawings illustrating my invention:-
Figure 1 is an elevation shewing cover displaced and socket removed.
Figure 2 an elevation of a socket, and
Figure 3 an elevation shewing the wrench or spanner fitted with socket and
applied to a hexagonal nut.
It consists of a handle or lever A. provided with an annular box shape
recess B at one end within which is an inwardly projecting tooth or catch C. One
side of this annular box is partly closed by means of a plate D through the centre
of which is an opening, the other side being left open is partly closed by means of
an annular cover E pivotted at one side to the handle A and arranged to close
against a stop or shoulder F formed upon the box.
Into this annular box a circular socket G having a central opening H corre-
sponding in size and shape to the nut or stud K to be operated upon is loosely
inserted, the circumference of this socket being furnished with peripheral teeth LL
arranged so as to engage with the fixed tooth C within the box.
In operation the action is as follows:-
A socket G of suitable size and shape having been inserted within the annular
box B, the pivotted cover E is then closed over the same, and the central opening H
in the socket G slipped over the nut or stud K to be turned.
A circular or reciprocating motion is then given to the handle or lever A which
causes the fixed tooth C within the annular box to engage with the peripheral
teeth L L upon the socket G and thereby cause it to revolve, carrying with it the
nut or stud K to be turned.
By reversing the handle so as to present the opposite face of the socket G to the
nut or stud K a reverse motion can be imparted thereto.
Spanners or wrenches thus constructed can be used in the same way as an
ordinary ratchet brace, any desired number of sockets varying in size and shape can
be used in turn and in the event of wear can readily be replaced.
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 wrench the combination of a lever or handle having an annular box at
one end thereof, provided with an inwardly projecting tooth, a socket loosely
mounted in said box and having peripheral teeth, and a central nut opening, a cover
of annular form pivotally attached to the said handle of the wrench and closing
against a stop or shoulder formed upon the box substantially as described.
2. Wrenches constructed and arranged for the purposes described and as illus-
trated on the accompanying sheet of drawings.
