PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of certain kinds of Window,
Door, and Drawer Catches and Fasteners.
We WALTER JOHN MAY, and ARTHUR EDWARD PADMORE, trading, as May
and Padmore, of Leopold Street, in the City of Birmingham, Brass Founders, do
hereby declare the nature of this invention to be as follows:-
This invention pertains to the manufacture, or to the production of certain kinds
of catches and fasteners for windows, doors and drawers, such, for example as
catches and fasteners for fanlights, cupboards, casements, drawer flaps, doors, drawers
or the like. :
The said kind of fastener, generally comprises, or consists of four primary parts,
viz.-a box casing, with two opposite flanged sides; a traversing or reciprocating bolt
member, fitting and working within the said casing; a lever or looped lever
member, jointed, and adapted to withdraw the bolt, and a staple or striking plate.
The said primary parts of the fasteners, as ordinarily manufactured, are made, or
produced, by the process of casting.
According to our invention, we make the said parts, or the said primary parts or
members, from sheet, rolled, or wrought metal, by means, or by the process or
processes, as hereinafter described.
Thus we make the box casing member part from sheet metal, by the process of
stamping and raising, and subsequent piercing and clipping. The bolt part is made
from rolled strip metal of its cross section; the lever, or the loop-lever part is cut
out from sheet metal, and then subsequently operated upon by rounding off tools,
which transform the square or angular edges into rounded or other forms, while the
staple plate is made from cut out sheet metal, raised into the figure desired.
In the production of the box casing or box frame, a blank of thick sheet metal,
of an area greater than the article to be produced, is taken, and then subjected to
the operation of a stamp, which sinks within the middle of the said blank, a square
and slightly taper-sided recess, or well, of a depth sufficient for the clearance of the
bolt, and of a length less than the length of the bolt, and of a breadth greater than
that of the bolt.
The square recess or well thus fashioned from out of the metal of the blank, is
surrounded by walls, and by flanged or flap edges. The front wall of the said
recess, is pierced to the cross section of the head of the bolt, whilst the middle of
the back wall, is pierced with a centrally disposed hole, of the size and shape of the
cross section of the after part or stalk.
The metal of the flanged edges on a line with the outside boundary edging of the
back and front walls, is clipped, whilst the flanges or flaps, which constitute the
attachment plates of the fastener, upon the two opposite sides of the said box
recess, are squared by clipping, and then subsequently pierced with screw, or both
screw and rivet holes.
The bottom middle part is also pierced with a longitudinal. slot, wherethrough
the stem of the operating lever, passes.
This hollow stamping or sheet metal shell, is then inverted, and an underside
sheet metal covering plate, preferably of the superficial area of the said underside,
is then attached, and which supplementary plate has within its middle, a joint
sinking, with a cross piercing, to which the lower end of the lever is connected and
jointed by a cross pin or rivet.
In making the bolt, a strip of metal is drawn or rolled, having a cross section of
the longitudinal section of the bolt, to be made. Then by means of cutting-out tools,
the holte are out-out croservice from the said sectioned métal:

page_text: Thus, the strip of sectioned metal, has a semicircular shaped rib front part,
terminated by a shoulder, which terminates in a flat plateau, or plain to the after
part.
The bolt to be cut out from the said metal has a semi-circular or shamfered head,
with a flat body part, of a less thickness than the head, pierced about its middle
with a hole, wherethrough the shank of the operating lever passes, for the
working of it.
+
The after part of the bolt, is terminated by a stalk, which is rounded or fetched
up from the said blank, by shaping or rounding tools.
The said bolt, instead of being made from cut-out sectioned strip metal, may be
made from plain sheet metal, with the fore part turned upon itself into a head,
which is shaped or shamfered by press tools, or by stamping.
The lever part, which consists of a curved shank part, a pivot hole pierced inner
end, and a looped outer end, is cut from out of plain sheet metal, of the thickness of
the said lever, then by a pair of rounding off tools, the angles or the sharp edges of
the cut out lever, pull, pusher or the like, are rounded or taken off, hence the
production of a cut out sheet metal lever or the like, with the parts, or whole, of a
circular or rounded figure.
.
In making the staple or striking plate we produce the same from strip metal,
either drawn or rolled to the section of the said plate, and then cut off transversely
by a tool or cutter, or made from a strip of sheet metal, bent into an arched or
other desired figure.
The application of our invention to the production of other fasteners, differs in no
essential respect from its application to a bolt as herein described.
The whole of these said component parts are fitted together by rivetting or other-
wise, to constitute a complete fastening or catch, and with a feather or other spring
located within the casing, and taking its bearing upon the bolt, for taking the said
bolt and lever back to their normal positions.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of certain kinds of Window,
Door, and Drawer Catches and Fasteners.
We, WALTER JOHN MAY, and ARTHUR EDWARD PADMORE, trading as May
and Padmore, of Leopold Street in the City of Birmingham, Brass Founders, 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 pertains to the manufacture, or to the production of certain kinds
of catches, and fasteners for windows, doors, and drawers, such, for example, as
catches and fasteners for fanlights, cupboards, casements, drawer flaps, doors,
drawers or the like.
The said kind of fastener generally comprises, or consists of, four primary parts,
viz., a box casing, with two opposite flanged sides; a traversing or reciprocating
bolt member, fitting and working within the said casing; a lever or looped lever
member, jointed, and adapted to withdraw the bolt, and a staple or striking plate.
The said primary parts of the fasteners, as ordinarily manufactured, are made, or
produced, by the process of casting.
According to our invention, we make the said parts, or the said primary parts or
members, from sheet, rolled or wrought metal, by means, or by the process or
processes, as hereinafter described.

page_text: Thus, we make the box casing member part from sheet metal, by the process. of
stamping and raising, and subsequent piercing and clipping. The bolt part is made
from rolled strip metal of its cross section; the lever, or the loop lever part is cut out
from sheet metal, and then subsequently operated upon by rounding-off tools, which.
transform the square or angular edges into rounded or other forms, while the staple
plate is made from cut-out sheet metal, raised into the figure desired.
In the production of the box casing or box frame, a blank of thick sheet metal,"
of an area greater than the article to be produced, is taken, and then subjected to
the operation of a stamp, which sinks within the middle of the said blank, a square
and slightly taper-sided recess, or well, of a depth sufficient for the clearance of the
bolt, and of a length less than the length of the bolt, and of a breadth greater than
that of the bolt.
The square recess or well thus fashioned from out of the metal of the blank, is
surrounded by walls, and by flanged or flap edges. The front wall of the said
recess, is pierced to the cross section of the head of the bolt, whilst the middle of
the back wall, is pierced with a centrally-disposed hole, of the size and shape of the
cross section of the after part or stalk.
The metal of the flanged edges on a line with the outside bountlary edging of the
back and front walls, is clipped, whilst the flanges or flaps, which constitute the
attachment plates of the fastener, upon the two opposite sides of the said box
recess, are squared by clipping, and then subsequently pierced with screw, or both
screw and rivet holes.
The bottom middle part is also pierced with a longitudinal slot, wherethrough
the stem of the operating lever passes.
This hollow stamping or sheet metal shell, is then inverted, and an underside
sheet metal covering plate, preferably of the superficial area of the said underside,
is then attached, and which supplementary plate has within its middle, a joint
sinking, with a cross piercing, to which the lower end of the lever is connected and
jointed by a cross pin or rivet.
In making the bolt, a strip of metal is drawn or rolled having a cross section of
the longitudinal section of the bolt to be made. Then, by means of cutting-out
tools, the bolts are cut out crosswise from the said sectioned metal.
Thus, the strip of sectional metal, has a semi-circular shaped rib front part,
terminated by a shoulder, which terminates in a flat plateau, or plain to the after
part.
The bolt to be cut out from the said metal has a semi-circular or shamfered head,
with a flat body part, of a less thickness than the head, pierced about its middle
with a hole wherethrough the shank of the operating lever passes, for the working
of it.
The after part of the bolt, is terminated by a stalk, which is rounded or fetched
up from the said blank, by shaping or rounding tools.
The said bolt, instead of being made from cut-out sectioned strip metal, may be
made from plain sheet metal, with the fore part turned upon itself into a head,
which is shaped or shamfered by press tools, or by stamping.
The lever part, which consists of a curved shank part, a pivot hole pierced inner
end, and a looped outer end, is cut from out of plain sheet metal, of the thickness
of the said lever, then by a pair of rounding-off tools, the angles or the sharp edges
of the cut-out lever, pull, pusher or the like, are rounded or taken off, hence the
production of a cut-out sheet metal lever or the like, with the parts or whole, of a
circular or rounded figure.
In making the staple or striking plate, we produce the same from strip metal,
either drawn or rolled to the section of the said plate, and then cut off transversely
by a tool or cutter, or made from a strip of sheet metal, bent into an arched or
other desired figure.
The application of our invention to the production of other fasteners differs in no
essential respect from its application to the bolt as herein described.
The whole of these said component parts are fitted together by rivetting or

page_text: otherwise, to constitute a complete fastening or catch, and with a feather or other
spring located within the casing, and taking its bearing upon the bolt, for taking
the said bolt and lever back to their normal positions.

Figure 17 represents front and side elevations of an unfinished lever, as cut out
from the metal Figure 18.
Figure 19 is a finished lever.
Figure 20 is a plan, side and edge view of the staple plate.
Figure 21 is the shank from which the staple plate is made, and which constitutes
no part of our invention, while
Figure 22 shows the application of our catch to a window or fanlight.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
In the fastening, a is an enclosing casing, with opposite flaps or side flanges a².
is an underside cover plate of the said casing, with a well or recess 63, sunken
within its middle, and adapted to receive the inner or joint end e², of a loop ended
lever which is jointed or turns about a centre pin d, carried by the walls of the
said well ², as a double sided bracket. e is a reciprocating and sliding bolt, working
within the said casing, and adapted, when shot or pushed home by the spring h, to
engage with the staple plate f.
In making the cover plate, we proceed as follows:-
We take a blank i, (Figure 8) of sheet or rolled metal, and by stamping and
raising, we sink within the middle of the said blank, a rectangular shaped well or
recess a³, having slightly and downwardly tapering sides a, and which well or
recess, when inverted, constitutes the box casing, whilst the flaps or flanges a²,
disposed upon the two opposite sides of the longer direction of the said casing,
form the means whereby the said casing is attached to the under cover plate and to
an article to which the fastening is to be applied.

page_text: By tools, the irregular marginal edges up to the dotted lines Figure 9, are
clipped, and then by a subsequent operation or operations, the holes a³, a, a', are
formed or pierced, and also the holes as, a³, formed in the flaps a².
In making the cover plate b, we take a blank Figure 13, and by stamping tools,
we sink within the middle of the same, a well or recess 62, which constitutes, as it
were, a hanging bracket, and within which the fulcrum end of the lever c, is
pivoted and works.
The screw and rivet holes 63, 64, are subsequently cut out by piercing tools.
In the making of the bolt, we take a long strip of metal e², Figure 15, of the
cross section e³, and from the said sectional metal, we cut out a bolt blank e*,
having a stem or stalk e³, and a headed catch end e. Then by a subsequent
process, or at the same time, we pierce the said bolt at e', wherethrough the shank
of the lever c, passes.
By means of shaping tools, the shank e³, is next operated
upon, and also the opposite sides of the hole e', hence the finished bolt Figure 14.
In making the lever c, the blank Figure 17 is cut out from the strip metal
Figure 18, which is of the same thickness as the intended lever, then by a
subsequent process, the fulcrum end e³, is pierced with a pivot hole c³, and the sharp
boundary edges c¹ of the loop part rounded off.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First In the box casings or covers of window, door, drawer and like fastenings
or catches as described, making or fashioning the same from sheet metal, or by
hollow stamping or shaping sheet metal, in the way and by the means as described
and set forth.
Secondly-A sheet metal hollow stamped casing or cover of window, door and
like catches or fastenings, with piercings and flaps or flanges as set forth.
Thirdly-In the under cover of window, door and like catches or fastenings,
making the same from sheet metal, with a well or recess sunken within its middle
part for the purpose substantially as described and set forth.
Fourthly In the bolts of window, door and like catches or fastenings, making
the same from drawn or strip metal of the transverse section of the edge of the bolt,
as set forth.
Fifthly In bolts made from section metal, as in the preceding claim,
fashioning or rounding the stem or stalk part, and also the lever opening there-
through, by tools, substantially as described and set forth.
:
Sixthly In the levers of window, door and like catches or fastenings, making
or cutting out the same from sheet or strip metal, and if necessary, subsequently
operating upon the blank by rounding-off tools, as set forth.
Seventhly-In window, door, drawer and other like catches or fastenings,
making the combined parts from sheet, strip or drawn metal, in the way or ways,
and by the process or processes of manufacture, as described and set forth.
