PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Ring Sash-lifts and like
Articles.
I, WILLIAM HENRY ROOKE, of 71, Great Hampton Row, in the City of
Birmingham, Brassfounder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture or production of ring sash-lifts and
other like articles from pressed or cut-out sheet metal, by the process or by the
means as hereinafter described, whereby the said articles are simplified in the
process of making, and the cost of their production greatly reduced.
The said article is made of two component parts, viz., an attachment part or
flat bracket, and a ring or lift part, affixedly connected to the other part by
rivetting, clinching or the like.
Thus, in making the attachment part, I cut the same out from sheet or strip
metal, with a slot piercing directed through its middle, and which piercing is
preferably countersunk, or made slightly larger upon its under or back side, so
as to admit of the ends of the loop part, as hereinafter described, being expanded
at back, after the same have been passed through the said slot or opening.
The loop part is made from a length of sheet or strip metal, bent up into the
form of a loop or ring, and with the ends of the same brought together into the
form of a short flange, which is passed from the front side through the slot, and
is then rivetted at the back.
The terminal ends of the loop part may, if necessary, be shouldered, so that
the slot in the attachment plate part is of a like breadth and length as the said
flange part or parts to be received by it.
Thus, the bracket or ring article consists of an attachment plate, with a ring
like loop standing at right angles to it, and with the said loop connected to the
base part at or about its middle.
In carrying out a further form of my invention, 1 may make the ring part from
a cross length of tubing, having a flanged or web bottom part, which is passed
through the piercing in the plate, and rivetted at the rear.
Or the said ring may be attached to the plate by separate rivets.
The application of my invention to other similar articles differs in no essential
respect from its application to a sash-lift, as described.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Ring Sash-lifts and like
Articles.
I, WILLIAM HENRY ROOKE, of 71 Great Hampton Row, in the City of
Birmingham, Brassfounder, 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 manufacture or production of ring sash-lifts and

page_text: other like articles from pressed or cut-out sheet metal, by the process or by the
means as hereinafter described, whereby the said articles are simplified in the
process of making, and the cost of their production greatly reduced.
The said article is made of two component parts, viz., an attachment part or flat
bracket, and a ring or lift part, affixedly connected to the other part by rivetting,
clenching or the like.
Thus, in making the attachment part, I cut the same out from sheet or strip
metal, with a slot piercing directed through its middle, and which piercing is
preferably countersunk, or made slightly larger upon its under or back side, so as
to admit of the ends of the loop part, as hereinafter described, being expanded at
back, after the same have been passed through the said slot or opening.
The loop part is made from a length of sheet or strip metal, bent up into the
form of a loop or ring, and with the ends of the same brought together into the
form of a short flange, which is passed from the front side through the slot, and is
then rivetted at the back.
The terminal ends of the loop part may, if necessary, be shouldered, so that the
slot on the attachment plate part is of a like breadth and length as the said flange
part or parts to be received by it.
Thus, the sash lift or ring article consists of an attachment plate with a ring like
loop preferably standing out at right angles to it, and with the said loop connected
to the base part at or about its middle.
In carrying out a further form of my invention, I may make the ring part from
a cross length of tubing, having a flanged or web bottom part, which is passed
through the piercing in the plate, and rivetted at the rear.
The application of my invention to other similar articles differs in no essential
respect from its application to a sash-lift, as described.
Figure 1 of the accompanying drawing represents in plan, a ring sash-lift made
according to one form of my invention.
Figure 2 represents a side elevation of the same.
Figure 3 represents an end view of either of the said Figures 1 and 2, and
Figure 4 is a transverse section on the dotted lines A B Figure 1.
Figure 5 is an inverted plan of the said ring sash lift.
Figure 6 represents an underside plan and edge view of the attachment part of
the said ring lift and Figure 7 represents in plan and edge view the strip of metal
from which the ring sash lift is made.
In Figures 1 to 7, a is the attachment plate, made from thin strip metal with
countersunk or other holes a', and a middle piercing or slot a³, slightly flared upon
its underside for receiving the expanded ends or flanges 6, of the metal of the
shank 6 of the ring part b, which is made from a length of strip metal Figure 7.
Thus the sash lift consists of an attachment plate a, having a loop part,
standing outwardly at right angles to it, and with the said loop b, connected to the
base part at or about its middle by rivetting.
Figure 8 represents a modified form of my invention, Figure 9 is an edge view
thereof with a part in section, and Figure 10 is a topside plan of the base plate
showing the shape of the middle piercing wherethrough the shank of the ring part
passes and is there rivetted.
In this arrangement the ring or loop b, is made of convex or half round sectioned
metal, with the convex coming upon the inner side of it. a is the plate, a the
piercing and b is the ring whose shank passes through the said piercing a², and
is there rivetted at 6³.
Figure 11 represents a still further form of my invention and Figure 12 a plan
of the same.
In this arrangement, the attachment plate a, is in the same general plane as the
ring b, or in the same general plane as the shank 6, of the loop or ring, which may
be of any figure as desired. is the rivetted part lying within the slot a³, in the
plate.
Figue 13 represents the detached parts of a ring liff constructed according to a

page_text: modified form of my invention. In this arrangement the shank part 6, of the
ring b, has abutment shoulders, whereas in the preceding figures the abutment is
made by the underside of the ring adjacent to the shank taking a bearing upon the
topside of the attachment plate.
Figure 14 represents a length of drawn tubing from which the ring part of the
lift may be made. This tubing consists of a tubular part 6, with a flange part b³,
so that by cutting the same up transversely into ring-like segments, and securing
the flange part thereof, within the countersunk slot a, in the plate a, (Figure 15)
by rivetting, a ring sash lift is thus formed.
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 :-
First. In ring or loop sash-lifts and like articles making the same from two
parts formed from sheet or strip metal, and with the one or ring part rivetted
or connected to the other or attachment part by the means and in the ways
substantially as described and set forth in the several figures of the drawings.
Secondly. Making the ring parts of sash lifts and their attachment flanges or
shanks from a length of drawn tubing or hollow section metal Figure 14 having
a flange or rib upon its underside, substantially as described and set forth.
Thirdly. The improvements in the manufacture of ring sash lifts and other
articles as and by the means substantially as described and set forth.
Dated this 26th day of January 1894.
