Improvements in Sashes or Glazed Doors for Clock Dials.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, 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. :-
This invention relates to an improvement in sashes for clock-dials of the class of
sashes commonly known to the trade as "French Sashes," the object being to produce
of the type mentioned, a sash which shall not only be very much cheaper than the
French sash of commerce, but which shall be more convenient in use, and present
fully as attractive and elegant an appearance.
With these ends in view, the invention consists in a sash for clock-dials having
certain details of construction and combinations of parts as will be hereinafter
described and pointed out in the claim.
In the accompanying drawing:
:-
Figure 1 represents a view in front elevation of a clock-dial sash constructed in
accordance with this invention.
Figure 2 a sectional view thereof.
Figure 3 an enlarged sectional view.
In carrying out the invention, a heavy annular sash-band A is formed by casting or
otherwise, which will ordinarily be produced with more or less elaborate ornamentation
in relief. This band is secured by its rear face to the forward edge of an annular sheet-
metal sash-flange B, which extends rearward at a right angle to the vertical plane of
the band, which together with the said flange, forms the sash proper. The flange
and ornamental band may be secured together in any desired manner. As shown, the
rear face of the band is formed with a very narrow shoulder a, which is encircled by
the extreme forward edge of the flange, as clearly shown in Fig. 3, the flange and
band being soldered, screwed, riveted, swaged or otherwise secured together, or, if
desired, the band may be cast upon the forward edge of the flange. As herein shown,
the glass C is laid against the inner face of the band, and held in place by means of a
light ring D, secured within the forward edge of the flange. The dial E, which may
be of any approved construction, is itself mounted in the inner edge of a beveled
mat F, struck up from light sheet-metal, and preferably made highly ornamental.
The said mat F is secured to the said sash-flange B by means of a hinge G, of any
suitable construction. It should also be mentioned that the mat is formed with a
slightly beveled shoulder F¹, which is made small enough in exterior diameter to
permit the sash-flange B to readily pass over it. As this is not a friction fit
like that relied upon in a French sash to hold the sash in its closed position with
respect to the mat, fastening means are provided which are here shown to consist
of a retaining point H formed in the shoulder of the mat, and a retaining-socket H¹
formed in the sash-flange B, but these fastening devices may be replaced by any other

page_text: suitable construction. By forming the sash-band and sash-flange of the sash
independently of each other, the expense of turning a cast sash-flange down in a
lathe is avoided, and the production of a sash-band in soft metal is permitted,
more ornate than it is practical to make in hard metal with an integral sash-flange.
The necessary tumbling of the exterior shoulder of the mat required to secure a
friction fit between it and the sash flange is also avoided. This improved sash is
therefore not only very much cheaper to produce than the ordinary French sash, but
it may be made even more elegant in appearance, and is vastly more convenient
in use.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the saine is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is:―
In a sash for clock-dials, the combination with an independently formed
ornamental sash-band, of a sheet-metal sash-flange formed independently of the said
sash-band, secured by its forward edge to the rear face thereof and extending rear-
.wardly therefrom at a right angle to the plane thereof, the said band and flange
together forming the sash, a dial, a sheet-metal mat in which the dial is mounted
and which is formed with an external shoulder of smaller diameter than the said
sash-flange, a hinge for securing the sash to the said dial-mat, and means applied
to the said mat and the said dial-flange for securing the sash in its closed position
with respect to the mat, substantially as set forth.
Dated this 22nd day of December 1898.
