Improvements in and in the Manufacture of Sorew and like
Sockets.
I, PHINEHAS EDWARD AYTON of the Firm of Thomas Pemberton and Sons,
of Livery Street, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the countersunk and open bottomed conical cups known
in commerce as screw sockets and generally used as a seating for the heads of
Ferews or their equivalents employed in securing together the meeting bars of
window sashes, and thus preventing such windows from being clandestinely opened,
although the said sookets are applicable to other purposes.
The principal object of my invention is to prevent the said countersunk sockets
from being withdrawn after having been inserted in position.
The socket consists of a conical shaped cup, with a square or other irregular-
shaped open bottom with the boundary edges of the same formed into separated
fangs or teeth with their extreme tips turned back or directed outwardly alike unto
hooks, which, when expanded by the driving of the screw through the socket or
by a special tool, are forced outwardly or displaced laterally into the wood of an
article in which it is inserted and the bottom is caused to assume a circular figure,
whereby the said socket is permanently retained in position or prevented from being
withdrawn.
In carrying out the manufacture of such sockets according to one form of my
invention, I take a blank of sheet metal and cup the middle of the same and then
by a pair of tools clip the top edges, forming a conical or dish-shaped blank, the
bottom of which is then star-pierced with the points of the star making the
divisions between the metal forming the fangs or teeth, which are by a further
process or pair of tools, forced downwards or turned outwards, leaving a square or
other angular sided bottom with the said sides separated by slits.
The said sockets may be also made by stamping the same from metal in a soft
state or may be made by casting and subsequently fanged and finished by suitable.
tools.

Improvements in and in the Manufacture of Screw and like
Sookets.
I, PHINEAS EDWARD AYTON of the Firm of Thomas Pemberton and Sons,
of Livery Street in the City of Birmingham, Manufacturer, 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 the countersunk and open bottomed conical cups known
in commerce as screw sockets, generally used as a seating for the heads of screws
or their equivalents employed in securing together the meeting bars of window
sasher, and thus preventing such windows from being clandestinely opened,
although the said sockets aro applicable to other purposes.
The principal object of my invention is to prevent the said countersunk sockets
from being withdrawn after having been inserted in position.
The socket consists of a conical shaped cup, with a square or other irregular-
shaped open bottom with the boundary edges of the same formed into separated
fungs or teeth with their extreme tips turned back or directed outwardly alike unto
books, which, when expanded by the driving of the screw through the socket or
by a special tool are forced outwardly or displaced laterally into the wood of an
article in which it is inserted and the bottom is caused to assume a certain figure,
whereby the said socket is permanently retained in position or prevented from
being withdrawn.
In carrying out the manufacture of such sockets according to one form of my
invention, I take a blank of sheet metal of a suitable thickness, such as represented
in Figure 1, and cup the middle a of the same as shown in Figure 2, then by a
pair of tools I clip away the surrounding metal a, forming a conical or dish-shaped
blank a', as shown in side elevation in Figure 3, and in vertical section in Figure 4,
the edges b, of which are further clipped or rounded off, when the blank assumes
the form shown in underside plan in Figure 5, in section in Figure 6, in topside
plan in Figure 7 aud in side clevation in Figure 8.
The bottom c, is then star-pierced at c', with the points o³, of the star making
the divisions between the metal forming the fangs or teeth c as shown in topside
plan in Figure 8, sido elevation in Figure 10, underside plan in Figure 11, and
cross section in Figure 12; next by a further process or pair of tools, the said
fanga or teeth are forced downwards or turned outwards, leaving a square or other
angular sided hole d in the bottom with the sides d', of the same separated by the
slits d', as shown in topside plan in Figure 13, side elevation in Figure 14, under-
side plan in Figure 16 and vertical section in Figure 16, the said last four views
representing the improved screw socket e, in its finished state.
Figure 17 represents a section of the said socket e, applied to the countersunk
mouth end f, of a screw hole f, but prior to the insertion of the screw thereinto,
whilst Figure 18 represents the said socket, with the screw g, introduced and
driven fully home, whereby the fangs o, are opened outwards and forced into the
wood, as shown.
The said sockets may be also made by stamping the same from metal in a soft
state or may be made by casting and subsequently fanged and finished by suitable
tools.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the saine is to be performed, I declare that what I
claim is :-
First. A screw or like socket. provided at its lower end. or at the outer walls

page_text: with separated fangs or teeth, which are expanded outwardly and driven into the
wood or other material in which the said socket is placed by the act of forcing
home a screw, substantially as and for the purpose described.
Secondly. A screw or like socket, provided at its lower end, or at its outer walls,
with fangs or teeth, separated from one another by piercings or splits, so as to
admit of the said fangs being opened out and driven into the wood or other
material by the act of forcing home a screw, substantially as and for the purpose
described and set forth.
Thirdly. Making screw and like sookets from sheet metal by the process
described and set forth.
