Improvements in Vehicle Windows.
1, SAMUEL SIDNEY BROMHEAD of 97 Newgate Street, London, E.C., Patent
Agent, (Communicated), 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 that class of Vehicle windows in which the sash slides
upwards in the frame to close the window and downwards into a pocket to open the
window and is applicable to all vehicles in which such windows are used.
The invention consists in the details of construction and arrangement substantially
as illustrated in the drawings, hereinafter described and subsequently pointed out in
the claims.
The frame of this window is mounted in the vehicle in the usual and well known
way and the sash is movable in this frame, sliding up and down in rabbits or grooves
in the inside face of the frame. The sash is fitted with a proper and convenient glass.
Referring to figure 1, A, designates the back of one of the window frame posts,
and C, the front thereof. This post is so constructed that through its length runs the
groove or rabbit G, G. There are two of these groves one on each side of the window.
The upper parts G, of the grooves being in either side of the window, on the inside
of the jamb, and the grooves G' lead down into a pocket in the panel work of the
vehicle. These grooves G¹ form the edges of the pocket and extend through the
whole depth thereof. Into this pocket the sash slides downward when the window is
opened. In the jamb about half way from the top to the bottom of the window is
placed the spring D, secured to the jamb by the plate D³, so that it will press the
frame B, of the sash; but so that while the spring by its resilience keeps the window
from rattling still at the same time does not exert so much pressure but that the sash
may be easily slipped up and down while the spring is bearing on it. In the side of
the pocket at G1, is placed another spring E, like the one just described. It is set
half way from the top of the pocket to the bottom thereof. This spring is mounted

page_text: upon the plate E', like that just described and like it bears on the sash when the lower
end thereof is slipped down low enough to pass under the said spring E. Thus in
whatever position in the window or in the pocket the sash may be placed it will not
rattle by reason of its being pressed against the window casing by one or both of said
springs. There is one of these springs on each side of the window and one on each
side of the pocket. The sash may be pushed down with the hand, or elevated by a
strap or cord in the well known way B, illustrates the sash in the window and the
dotted outline at B1 illustrates the same sash in the pocket.
Figure 2 and 3, illustrate the spring D, and its accompanying mechanism, in detail.
In figure 2, the plate D¹ is illustrated in back view. In figure 3, in edge view. The
ends e, e of the spring D are narrowed and pass through the slots f, and f' near the
ends of the plate D, each in the form of a hook. To the ends of these hooks are
attached the ends of the spring d, so that it will assist the resilience of the spring D.
The plate D carrying the springs as illustrated, is fastened or screwed upon the
jamb of the window as hereinbefore described and operates upon the sash as specified.
Or instead of using two springs as described one above the other on the window jamb,
only one may be used on either side by attaching it to the sash instead of the jamb,
in which case the spring will travel with the sash, bearing always, upon the window
jamb. Fig. 4, illustrates a modification of the spring hereinbefore described. The
modification consists in the addition of the clip D×, which may be permanently
swedged upon the middle of the spring D. This modification is used for the tops of
windows where it is desired to prevent the sash from shaking and rattling. The
positions of the various parts of the window with relation to the said spring D, and
clip D, are illustrated in section in Figure 5 each part being designated by its proper
letter, as herein before specified.
The shoulder a, and notch b, and the sash B of Figs. 1, and 5, illustrate how the
sash is held in place while it closes the window.
Having now fully described and ascertained the nature of my invention, and how
the same is constructed and performed, I do hereby declare that what I claim as my
Invention and desire to secure by letters patent is,
1. The combination with the window frame A, C, and the sash B, of the springs Dd,
plate D', spring E, and plate E¹, all substantially as and for the purpose set forth.
2. In a vehicle window the combination, with the window frame A, C, and the
sash B, of the spring D, the spring d, the clip Dx and the plate D' substantially as
and for the purpose set forth.
