Improvements in Sash Fasteners.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
eclare the nature of this invention and in what manner the same is to be
erformed to be particularly described and ascertained in and by the following
tatement:
This invention consists of a device for automatically fastening or locking sashes,
so that the same may not be lowered or raised without the proper manipulation of
the device, the construction being hereinafter set forth.
In the accompanying drawing
-
Figures 1 and 2 represent partial side elevations and partial vertical sections of
a sash fastener embodying the invention, taken respectively on lines x, x, and y, Y,
of Figure 3.
Figure 3 represents a transverse vertical section on line z, z, Figure 1.
Similar letters of reference indicate corresponding parts in the several figures.
A designates a dog which is mounted on the ears B, the latter being provided
with a bottom plate C, adapted to be secured to the meeting rail of the lower
sash.
The face of said dog is elliptical in its nature, or eccentric to the axis thereof,
and the same is adapted to come in contact with the stile of the upper sash, it
being evident that there is a wedging and biting action of the dog with the upper
sash when the lower sash is raised or the upper sash is lowered, and thus the
fastening or locking of the sashes is assured, and improper opening thereof is
prevented, the action being the same whether the sashes are entirely closed or
partly open.
In order to cause the dog to hold with greater frictional effect on the sash,
the face thereof is clad with a piece of yielding material, such as soft rubber, the
same pressing against the upper sash, and also serving to prevent injury to the
woodwork, said piece being set in a recess in the dog, and held therein by a
dove-tailed joint or other fastening.
Pivotally connected with the back of the dog, and between its face and its
pivot, is a locking arm D, which has, thereon laterally-projecting lugs E, so
disposed that when the dog is in locking position, said lugs bear against shoulders E¹
at the top of the ears B, and above the journals of the dog, thus preventing
outward motion of the arm, and consequent release of the dog. When however,
the arm is properly raised, the lugs are cleared of the shoulders E', and thus the
lugs may ride over the tops of the ears, and the dog thrown back as shown in
Figure 2, when the sashes may be raised and lowered as desired.
Embracing the ears B is a sheath F, whose sides have lips G thereon, said lips
projecting inwardly and overhanging the upper portions of the journals H of the
O dog A, whereby said journals cannot be lifted from the ears B, in which they are
seated, or displaced by an implement inserted from below, or otherwise directed
against the journals.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
5 my foreign correspondent, I declare that what I claim is :-
:-
First. A sash fastener consisting of a dog, ears in which said dog is journalled

page_text: the said eurs having shoulders above the journal bearings of said dog, and a
locking arm pivoted to said dog, and having laterally-projecting lugs adapted to
engage said shoulders, said parts being combined substantially as described.
Second. A sash fastener having ears, a dog journalled therein, and a sheath
embracing said ears having inwardly-projecting lips overhanging the journal of
said dog, said parts being combined substantially as described.
Third. A pivotal dog and bearing therefor, in combination with a sheath having
a lip which overhangs the journal of said dog, substantially as described.
