COMPLETE SPECIFICATION.
Improvements in the Construction of Spring-roller Fittings for
Sliding Windows and Shutters, and for other like uses.
I, ISAAC PEDLEY Junr., of Gower Terrace, Willenhall, Staffordshire, Iron' and
Steel Merchant's Manager, 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 has reference to those spring roller fittings which are fixed on sliding
window sashes and sliding shutters and doors to sustain the same in the frame of the
window, shutter or door respectively, either without the use of balance weights and
cords, or in addition thereto, to prevent rattling and make the sash, shutter, or
door move in its frame more easily. The said spring roller fittings are also some-
times used in the frame of the sliding window sashes, shutters or doors for like
purposes.
By constructing the said spring roller fittings in accordance with this invention
the cost of their production is considerably reduced and they are more effective for
the purposes stated.
I will describe my invention by referring to the accompanying drawings on which
Fig. 1 represents in back elevation, Fig. 2 in side elevation, and Fig. 3 in front
elevation, a spring roller fitting constructed according to this invention; Fig. 4 shews
the same fixed to a sliding window sash; Fig. 5 shews one of the springs of the same
and Fig. 6 represents a modified form of the said spring; Figs. 7, 8 and 9 illustrate
a slightly modified construction of the said spring roller fitting; Figs. 10, 11 and 12
shew a further modification and Figs. 13 and 14 a further modification.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
A spring roller fitting for the purposes stated constructed according to this
invention consists of a base plate a having fixed at one side flat springs preferably
four in number marked respectively 61, 62, c¹, c². The free ends of the two springs b¹²
are bent round and form bearings for the axle d of the roller e which is thus carried
between them and projects through a hole fin the plate a so as to project beyond the
same. The springs cle² press upon the springs 61 62 and help to retain the roller e in
its normal position (Figs. 2, 7, 11 and 13).
For a sliding window sash, shutter, or door, I usually use four of the spring roller
fittings above described two near the top and two near the bottom thereof recessed
into the sides of the sash, shutter, or door (see Fig. 4 where part of a sash g and the
sash frame h are shewn) and fixed by screws ii, the rollers e projecting and being
pressed against the sash frame by the springs 61 62, c¹ c², which may either be made
so strong that the friction set up will support the sash without cords and weights, or
the fittings may be used in combination with cords and weights to prevent the sash
rattling and make it run more easily.
Various methods of constructing the springs 6' 62 c¹ c² and fixing them to the plate a
may be adopted; for instance, the springs may either be made as parallel strips
separate from each other (Fig. 5) or two of them may be formed together (Fig. 6) or
they may be made in a piece with the plate a (see Fig. 13) which is then folded at
about one fourth its length from each end; and the springs may either be fixed to
the plate a by rivets (Figs. 1, 2 and 3) and separate strengthening plates jj. or the
rivets may be dispensed with and the springs or plates secured together by folling
one of them over the edges of the others as shewn for instance in Figs. 7, 8 and 9
where the sides of the strengthening plates jj are folded over the edges of the springs
and base plate; or the strengthening plates may be dispensed with and the springs
made with side projections (Fig. 12) which are folded over the edges of the base

page_text: plate a (Figs. 10 and 11) or the base plate may be similarly made with side
or end projecting parts which are folded over the springs and thus be secured
thereto.
It will be evident that the spring roller fittings above described are applicable
for use in many other ways than that shewn by Fig. 4, as for instance they may be
fixed to the side of the window sash, shutter, or door, so as to bear against the bead
of the frame or 'they may be fixed to the frame to bear against the sash, shutter, or
door.

In some cases I make the springs 662 so strong that I can dispense with the
springs c¹ e².
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
Spring roller fittings for sliding windows, sliding shutters and for other like uses
made in the several ways substantially as hereinbefore described with reference to the
accompanying drawings.
