PROVISIONAL SPECIFICATION.
Improvements in Holders for Sliding Sashes and Sliding Frames.
JOSEPH WHITE of 3 Barker Gate Nottingham, Lace Manufacturer do
hereby declare the nature of this invention to be as follows:-
A novel apparatus to be fitted to sashes of windows or other moveable frames,
obviating the necessity for sash cords, and weights; permitting the sash to be raised
or lowered and holding it automatically in the desired position.
It consists of a metal box fitted with a disc or wheel of india rubber, gutta
percha or other material, solid or inflated, acted upon from the back of the box by
a spring, or it may be minus the spring when desired.

COMPLETE SPECIFICATION.
Improvements in Holders for Sliding Sashes and Sliding Frames.
I, JOSEPH WHITE, of 3 Barker Gate, Nottingham, Lace 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, reference being had to the accompanying drawings and to the letters and
figures marked thereon, that is to say :-
My invention relates to a novel apparatus or holder adapted to be fitted to sashes
of windows, and other sliding frames, the employment of such apparatus or holder
obviating the necessity for sash cords and weights; permitting the sash to be raised
or lowered; and enabling the sash to be held automatically in any desired position.
To this end, the apparatus or holder consists of a metal box fitted with a disc or
wheel of india-rubber, gutta-percha or other suitable material, and either solid or
inflated, and by preference acted upon from the back of the box by a spring; but
if desired the spring may be dispensed with.
And in order that my invention may be readily understood, I will describe the
same fully with reference to the accompanying drawings, in which :-
Fig. 1 is a sectional elevation, and Fig. 2 a plan, of the apparatus or holder.
Fig. 3 is a horizontal section showing a portion of a sliding sash and its frame
with my apparatus or holder applied thereto.
Fig. 4 is an elevation, and Fig. 5 a plan, of a modified construction of the
apparatus or holder.
Fig. 6 shows this modified construction, in conjunction with a locking device, or
break, applied to a sliding sash.
Fig. 7 is a perspective view of the locking device or brake.
a is the metal box or frame, one or more of which are secured, by screws or other
suitable means, to each side of the sash as seen at Fig. 6. Each of these boxes or
frames is formed with bearing surfaces b, b, for the reception of the axle c of the
friction roller d. This roller is advantageously composed of india-rubber, gutta-
percha, or other suitable resilient material and may be solid, hollow, or inflated.
In the arrangement shown at Figs. 1 and 2 the box or frame a is formed with
comparatively deep bearing surfaces b, and is furnished with a loose bearing e
This loose bearing is
having bearing surfaces e' for the reception of the axle c.
acted upon by a curved ribbon, helical, or other spring f, situated at the back of
the box or frame, and retained in position by the pin g. This spring keeps the

page_text: resilient roller constantly pressed against the sash frame with sufficient force to
securely retain the sash, by friction, in any position to which it may be raised or
lowered. And by reason of the deep bearing surfaces in the box or frame, the
loose bearing and its roller are capable of receiving a certain amount of movement
inwardly against the tension of the spring f. When this spring is employed, the
roller may, if preferred. be composed of a non-resilient material.
Instead of mounting the resilient friction roller in a loose bearing acted upon by
a spring, as above described, I may mount the resilient roller in the bearing
surfaces formed in the box or frame itself, as shown at Figs. 4 and 5, and thus
dispense with the loose bearing and spring. In this case the friction necessary to
retain the sash in its various positions is produced by means of a locking device or
break consisting of a lever h which is pivotted to the sliding sash in the manner
shown by Fig. 6, and works in a slot formed in the sash. The extremity of the
lever 1, which comes against the sash frame, is preferably enlarged and roughened
at i, so as to enable it the better to grip the said sash frame and thus firmly retain
the sash in position when the lever is depressed in the direction of the
arrow (Fig. 6).
Although in the drawings I have shown the sash provided with only two of the
apparatus or holders, it is obvious that any required number may be employed, as
the weight of the sash may require. And although I have described and shown
my invention as applied to a sliding sash it can be applied in similar manner to
other sliding frames.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it to be
understood that I lay no claim to the locking device or break per se. but what I do
claim is:
1. The apparatus or holder for retaining sliding sashes, or frames, in any desired
position, consisting of a box or frame provided with a loose bearing carrying a
roller, composed of a resilient or non-resilient material, and a spring for acting
upon said bearing, substantially as described and shown with reference to Figs. 1, 2,
and 3 of the annexed drawings.
2. The modified construction of apparatus or holder, consisting of a box or casing
carrying a resilient roller, and adapted to be used in conjunction with a locking
device or break, substantially as described and shown with reference to Figs. 4,5,6,
and 7 of the annexed drawings, whereby the loose bearing and spring can be
dispensed with.
3. My improvements in holders for sliding sashes, or other sliding frames,
substantially as described and shown with reference to the annexed drawings.
