AN IMPROVEMENT IN THE MANUFACTURE OF METALLIC SASH LIFTS
Year: 1884

page_text: I CHARLES SHOWELL of the firm of Edwin Showell and Sons of Lower Loveday
Street Birmingham in the County of Warwick Brassfounders do hereby declare
the nature of the said Invention for "AN IMPROVEMENT IN THE MANUFACTURE
OF METALLIC SASH LIFTS" to be as follows:-
My Invention relates to such sash lifts as consist of a fixing plato having at its
middle and at right angles thereto an eye loop or ring in which the finger is
placed to lift the sash the sash lifter being usually screwed to the lower part of the
sash to be lifted,
My Invention consists in manufacturing the said sash lifts from sheet metal by
the following process or combination of processes.
I cut out at a press or stamp from sheet brass or other hard and strong metal or
alloy a T shaped blank the upright part of the said blank having a length
somewhat double that of the cross piece or cross head of the blank. From the said
cross pieco or heal of the blank the fixing plate is formed and from tlie long
upright part of the blank the eye loop or ring is made the said cyo loop or ring
being fashioned by the operation of tools worked in a press or stamp. The eyo
loop or ring thus formed has an attachment pieco projecting from it which piece is
made by the shaping operation to overlap or cross or partly cross the fixing plate.
By means of one or more rivets passed through the said attachment piece and the
fixing plate the eye loop or ring is secured to the said fixing plato. The fixing
plate is provided with countersunk holes by which it is screwed to the sash.
The sash lift is thus made from a single piece or blank of sheet metal.

page_text: I CHARLES SHOWELL of the firm of Edwin Showell and Sons of Lower Loveday
Street, Birmingham in the County of Warwick, Brassfounders, do hereby declaro
the nature of my Invention for "AN IMPROVEMENT IN THE MANUFACTURE OF
METALLIC SASH LIFTS" and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My Invention relates to such sash lifts as consist of a fixing plate having at its
middle and at right angles thereto, an eye, loop or ring in which the finger is
placed to lift the sash, the sash lift being usually screwed to the lower part of the
sash to be lifted.
My Invention consists in manufacturing the said sash lifts from sheet metal by
the following process or combination of processes.
I cut out at a press or stamp froin sheet brass or other hard and strong metal or
alloy, a T shaped blank the upright part of the said blank having a length
somewhat double that of the cross piece or cross head of the blank. From the said
cross piece or head of the blank the fixing plate is formed and from the long
upright part of the blank the eye, loop or ring is made the said eye, loop or
ring being fashioned by the operation of tools worked in a press or stamp. The
eye, loop or ring thus formed has an attachment pieco projecting from it which
piece is made by the shaping operation to overlap or cross or partly cross the fixing
plate. By means of one or more rivets passed through the said attachment piece
and the fixing plate the eye, loop or ring is secured to the said fixing plate. The
fixing plate is provided with countersunk holes by which it is screwed to the sash.
The sash lift is thus made from a single piece or blank of sheet metal.
Figure 1 of the accompanying Drawing represents in front elevation and edge
view, drawn of the full size, the T shaped blank from which the sash lift is made,
a being the cross piece or head of the blank from which the fixing plate is made
and the upright part or body from which the eye, loop or ring is made, the said
part b being about double the length of the cross piece a as represented. The said
blank having been perforated at c, c and d, d it is operated upon by a series of
pairs of pressing or stamping tools so as to give it successively the forms represented
in Figures 2, 3 and 4; that is to say, the body part is bowed at band the
attachment piece b³ at the end of the bowed part bent at the required angle as
represented in Figure 2. The part 6 is next shaped into the partly made ring eye
or loop marked in Figure 3 and by another operation the shape of the ring, eye
or loop is perfected as represented in Figure 4, the attachment piece 6 projecting
from the said ring being at the same time brought nearly parallel with the
fixing plate a. The end of the loop, eye or ring b' is next secured to the fixing
plate by means of a rivet at c which is passed through the holes c, c (see the
blank Figure 1) in the attachment piece b³ and fixing plate a as represented in
Figure 5. The fixing holes d, d in the fixing plate a are next countersunk. The
sash lift is thereby completed.
Where great strength is required at the junction of the eye, loop or ring b with
the fixing plate a, a double T shaped blank or a blank having a cross piece or
head a, at its ends may be used as represented in Figure 6. The said blank
Figure 6 is shaped in the manner described and represented with respect to the
T shaped blank Figure 1 so as to form from the part 6 the ring, loop or eye of the
sash lift. When the ring, loop or eye has been formed from the part b of
the blank Figure 6, the said ring has at its end the part a² of the blank which

page_text: part a constitutes a broad attachment piece of the same size and shape as tho
fixing plate a as reprosented in Figure 7, the abutting broad attachment piece aª
being secured to the plato a by a rivet at f. The attachment piece a³ and fixing
plate a are formed with countersunk holes for scrowing the sash lift to the sash as
described with respect to the fixing plate a Figure 5.
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
I claim is :-The improvement in the manufacture of metallic sash lifts herein
before described and illustrated in the accompanying Drawing; that is to say,
making each of the said sash lifts by taking a blank of sheet metal having a T shapo
or a double T shape and shaping or fashioning the body or middle of the blank so
as to form therefrom the eye, loop or ring of the sash lift, the said oye loop or ring
having at its end either a narrow or broad attachment pieco by which the said eyo,
loop or ring is secured by rivetting or otherwise to the fixing plate substantially
as described and illustrated,
