Specification Accepted, 2nd Nov, 1888.
I, WILLIAM YELLAND, Jr. residing at Brooklyn, in the County of Kings and
State of New York in the United States of America, gentleman, 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 :-
My invention relates to certain new and useful improvements in attachments for
window-sash and it consists in the novel construction and arrangement of the
parts thereof which will be more fully hereinafter described and pointed out in
the claims.
The primary object of my invention is to provide an attachment for window sash
whereby the same may be secured against a forcible opening, supported in an open
position for the purpose of ventilation or a part thereof may be employed. to raise
or lower the upper sash.
The secondary object of my invention is to provide a sash attachment which is of
simple and effective construction, strong and durable, easily handled and readily
operated and comparatively inexpensive in manufacture.
I attain these objects by the construction illustrated in the accompanying drawings
wherein like letters of reference indicate similar parts in the several views and
in which
Fig. 1 is a front elevation of sash showing my improved device in connection
therewith.
Fig. 2 is a perspective view of the parts of the device shown detached.
Fig. 3 is a perspective view of a part of the device showing a modification in
construction.
Fig. 4 is a similar view showing a further modification.
A and B indicate the upper and lower sash respectively. To the central top
portion of the upper sash A, a plate C is secured by any suitable means and is
provided on its rear face with an integral or attached socket e as shown in detail
Fig. 2 which receives a screw c¹ in connection with a ball, C₁, as shown in Figs. 1
and 2 or as shown in Fig. 3 with the screw of an eye C³. Where the ball, as C₁
is used, an aperture is drilled therethrough and receives a pin, which is secured
r/7

page_text: at its ends in the two forks of a yoke, d, carried on the upper end of a rod, D which
carries a ball or other ornament as, d, on its lower end for convenience in handling.
As shown in Fig. 3 the yoke, d is supplanted by an eye, d², which is linked with the
screw eye, C when said parts are used.
On the central top portion of the lower sash, B, a plate E is secured by suitable
means and is formed with a central slot e. and integral apertured ears, e', which are
situated at each end of the said slot, e, on the rear face of the said plate.
A metallic block, F is provided and is of such dimension as to pass through the
slot e in the plate E and have free vertical rocking movement therein. That part of
the block which is disposed at the rear face of the plate E is formed with an
aperture through which and the apertured ears, e¹, a pintle, e², is inserted and
secured and allows the said block to have a free vertical rocking movement. The
part of the said block situated on the outer side of the outer face of the plate, E is
constructed with a slot, e³, extending partially through said block from one side thereof
and which is adapted to engage the lower part of the rod, D. The outer front end
of the block is provided with a screw-threaded aperture extending therethrough and
communicating with the slot e therein.
This screw threaded aperture receives a thumb-screw S which is used to clamp the
lower end of the rod D in the slot in block, F. The portion of the block on the outer
side of the plate E is formed with extended shoulders e which limit the movement of
the said block by bearing against the adjacent surface of the plate E. As shown in
Fig. 4 the lower portion of the rod D may be formed with a corrugated or otherwise
roughened surface which acts conjunctively with a similar surface formed on the
sides bounding the slot, e³, of the block, F.
The uses and operation of my improved device are as follows; When I desire to
lock the sash against forcible opening, they are closed and the rod D placed within
the slot, e, in the block, F, and the thumb-screw S, screwed home thereagainst. If
it is desired to raise the lower sash, lower the upper sash or raise and lower the lower
and upper sash, and sustain them in these several positions, the rod D is disengaged
from the first adjustment described and resecured in the slot of the block F in the
adjusted position required.
In this latter instance the rod will extend some distance below the plate E on the
lower sash while in the first named adjustment the lower end thereof will be in close
proximity to the block F and therefore forms no depending projection.
If it is desired to use the rod D as a means of lowering and raising a heavy
upper sash it is released from the block F when it can be conveniently used for the
purpose.
The upper connection of the rod D is in the form of a universal joint and allows
a lateral as well as an inward and outward movement thereof. This movable
attachment of the rod D together with the rocking movement of the block F provides
an adjustment of the said parts to accommodate an abnormal position consequent
upon drawing the sash toward each other by raising and lowering the same, the
rod D being slightly forced at an outward angle when the upper sash is lowered and
the lower sash raised and vice versa.
I do not propose to limit myself to the precise construction herein set forth as
many changes in the formation of the minor parts might be made and substituted
for those shown without in the least departing from the nature or spirit of my
invention.
If I so desire I can construct the rod D flat or square and provide the lower
portion thereof with suitable perforations to be engaged by the shank of the
thumb screw S.
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 :
1. In a sash attachment, the combination substantially as before set forth of a rod
adapted to be attached at its unner and by a univermaat inint to L
c

page_text: an upper sash and a slotted clamping block capable of a rocking movement, adapted
to be secured to the central upper part of a lower sash to which the lower free end of
the said rod may be removably attached.
2. In a sash attachment the combination, substantially as before set forth, of a
plate provided with an integral screw threaded socket secured to the central top part
of the upper sash, a rod attached at its upper end to said plate and forming a
universal joint therewith, the slotted plate secured to the upper central part of the
lower sash and the slotted block capable of a rocking movement mounted in said
slotted plate and having a clamping screw mounted therein.
3. In a sash attachment the combination with the upper sash, of a socketed plate
attached to the upper part thereof a rod having a ball at the upper end thereof
pivotally mounted in a yoke and provided with a screw shank adapted to have a
movable bearing in the socketed plate to form a universal joint therewith, the lower
sash, the slotted plate formed with ears centrally secured to the upper part of the
lower sash, a slotted clamping block pivotally mounted in the slotted plate between
the ears thereof capable of having a rocking movement imparted thereto and the slot
thereof adapted to be engaged by the depending free end of the rod, the said block
also having shoulders formed therewith to limit its movement and a clamping screw
mounted in said block substantially as described.
4. In a sash attachment, a rod having a ball at its upper end pivotally mounted in
a yoke having a screw threaded shank adapted to movably engage with a socketed
plate centrally secured to the top of an upper sash, in combination with a self-
adjusting rocking clamping block secured to the top central part of a lower sash,
substantially as described.
