COMPLETE SPECIFICATION.
Improvements in and applicable to Window Sashes and Frames.
We, WILLIAM PATTENDEN of 246, Lancaster Road, Notting Hill, Carpenter
and Builder, and ANTON RINDESLAND of 5, East Row, Kensal Town, Merchant,
both in the County of Middlesex, 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 thereof that is to say
1-
This invention relates to certain improvements upon a prior application for
Letters Patent No. 11768 dated 10th July 1891, made by the present applicants.
The object of this invention is the construction of a bolt to be used in combi-
nation with the hanging casement styles and sashes described in the Specification
of the said prior application; and in carrying the same into effect we proceed
as follows:
In the drawings annexed hereto
Fig. 1. is a front view of the right hand hanging style of the said frames with
the Tended nose of the bolt shot to engage with the face plate of the pulley style
of the sash frame to lock therewith.
Fig. 2. is a top view partially in section of the sash hanging styles and sash
frame and bolt with hinged facing style of the boxing for the weights of the sash
frame; the dotted lines showing the facing style opened.
Fig. 3. is a face view of the device with the boli shot back to engage and lock
with the sash style.
Fig. 4, is a top view showing the bolt as in Fig. 3.
A is the sash style, B the pulley style of the sash frame, C the hanging style on
the right hand side of the frame, D are the hinge pintles serving for use and for
hanging the sashes to the hanging styles C, when the sashes are to be used in case-
ment form; E indicates the weight cord, and F the weight box of the sash frame,
G is the hinged facing style of the boxing serving to give access to the weights for
recording and so forth H is the bolt plate upon the pulley style to receive the T nose
of the bolt which we will next describe.
The metal plate a has two side wings a¹ a' of size so as to clip or saddle the
hanging style C, said plate a is provided with a face slot b, through which the
neck c of the double nosed bolt d d may work. The shank of said bolt works in
and through two slots provided in the side wings a' a² of the metal clip piece. One
end of the bolt, that is the end of the bolt that is towards the plate H is made
somewhat of T headed form i.e. two vertical slots e. e' are provided one above and
one below. The bolt plate H, is provided with a slot therein corresponding to the
size of the nose of the aforesaid bolt and to allow of the same to be shot into and
engage therewith. The second nose d' of the bolt is plain. The plate f, is
rivetted to the neck c, and has the finger catch g, for working the bolt to
and fro.
When the bolt nose d¹ is drawn back and shot into the sash style, the sash can
be raised and lowered along with the hanging styles, but when the bolt nose <¹ is
shot into the pulley style plate H, of the sash frame, the hanging style will be
locked to the sash frame and leave the sashes free to turn upon their hinges D, to
open in casement form.
If it be essayed to raise the sash when the bolt is so engaged with the plate H of
the pulley style the slot e at the head of the bolt will engage with the fixed plate
and prevent the sash being lifted off the pintles D.
The plate H is fitted in such position that the bolt d must be shot into the pulley
style before the sash can be released from the bolt (not shown in the drawing) on
the opposite hanging style. The slot in the lower edge of the T bolt will allow

page_text: the sash to drop for a short distance after the bolt d is shot and when the
opposite bolt may be shot also thus working the bolts together as a check means of
security.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what we
claim is :
1st. The improvements in window frames and sashes constructed and operating
as and for the purpose herein set forth and shewn by the drawings.
2nd. The double bolt applied to the hanging styles and working in combination
with the plate of the pulley style of the sash frame and with the sashes as herein
specified.
3rd. In combination with sash frames such as herein described the hinged facing
style G of the sash frame as and for the purpose set forth.
Dated this 24th day of October 1891.
