UMIDELE DI MOLTIVATION.
Door and Window Fastener.
1, JAMES N. EUWER, of New Castle, in the County of Lawrence, State of
Pennsylvania, United States of America, Salesman, 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 :-
The object of my invention is to provide a fastener that will hold a sash securely
at different heights, or a door closed, that shall be burglar proof, which fastener
shall be simple in construction and clicap to manufacture.
The invention consists in the novel details of improvement hereinafter more fully
explained and claimed.
Reference is to be had to the accompanying drawing forming part hereof,
wherein,
Figure is a vertical cross section of my fastener on the line c, c, Figure 2;
Figure 2 is a rear elevation of the fastener;
Figure 3 is an edge view of a window sash provided with the perforated plate:
Figure 4 is a plan view of the fastener its top plate being removed;
Figure 5 is a similar view the bolt being withdrawn ;
Figure 6 is a sectional plan view:
Figure 7 is a view similar to Figure 3, showing a modification;
Figure 8 is a sectional view through the window frame and
Figure 9 is a face view of the plate for holding the rod N.
In the drawing the letter A indicates the front plate of my fastener having a
casing B open on top and back, said casing being composed of side plates a, a, and
bottom plate b. The plate A has apertures a² for screws to hold it. D is a cover
for casing B, which preferably consists of an angle plate, one part d, of which
covers the back of casing B, while the part e, covers the top. The forward edge
of part e, of cover D, has a projection, that passes into aperture g. in main
plate A to hold the cover in position. The lower edge of part d, has a projection h,
that passes into a socket i, in bottom plate, the lower edge of part d, resting on
plate b, whereby cover D is supported at its outer part. E is a rod or bolt that
passes through plate A, and is secured to projection h. By this arrangement
cover D, is readily held in position, whereby a shallow casing and a cheap con-
struction is produced.
Within casing B is a sliding bolt F, for holding the sash G, or the part to be
secured, which bolt is shown rectangular at one part to slide freely without turning,
the forward part of said bolt projecting through aperture ; in plate A, to hold
sash G. In the rear of bolt F, is a socket 1, within which is a coiled spring H,
which rests at one end against the plate d. The spring H pushes bolt F, forward,
but when said bolt is pressed back spring H is compressed into socket 1. The
fastener should be placed in the frame of the window at the edge of the sash.
The
To push the bolt F, back within casing B, I use a bar I, having one edge m
inclined inwardly and forwardly which bar comes against a projection J on bolt F,
whereby when bar I is pushed forward bolt F will be moved inwards. Bar I, lies
between bolt and top plate e, and the straight side n, of bar 1 rides along a pro-
jecting ledge o on the inner side of plate A., upon which also cover D rests.
forward end of bar I is hook shaped at 12 to catch on projection J, to prevent bar I
from becoming detached from casing B and bolt F. The side of projection J that
engages side m of bar I is curved as shown, so that bar 1 will freely slide over the
same, and friction be reduced.
The bar I is held in the normal position (see Figure 4) by means of spring K,

page_text: interposed between an upright L on rod I, and a projection M; on cover D. The
ends of spring K, are preferably let into recesses on upright L and pro-
jection M respectively. To withdraw bolt F. rod is pushed forward so that
its inclined side rides on projection J. and moves bolt into the position shown
in Figure 5, thereby compressing springs H, K. When rod is released spring K
moves it backward and spring H moves bolt F forward.
I pass a rod N, through the side of the window frame O, the inner end of
which rod abuts against the end of rod 1, or upright L, the outer end being in
position to be pushed by the fingers. By removing rod N burglars will not be able
to raise sash G.
To retain bolt F withdrawn rod N, carries one or more projections t, between
which and the head I, are recesses v. The plate s, has an aperture w, through
which rod N, and its projections t, can pass (see Figure 8) when rod N is
pressed inwards into framework O, to operate bolt F the projections t, will pass
through plates, and aperture, bringing recesses, in line with plates, where-
upon when rod N is turned projections t, will pass in line with plate s, whereby
rod N will be held in place and bolt F pushed back to unlock the window.
The bolt F, enters apertures in a perforated plate P, over a groove on the
edge of sash G. The plate P may be placed in a recess on the edge of sash G.
The plate P can be of any desired length provided groove extends below the
lower end of plate P, so that dirt that may enter the groove through the apertures d²
will fall below.
The edges of apertures d² are contiguous so that the bolt can be readily entered
in them, whereby the sash can be held at any desired height. The contiguous
edges of apertures d² are preferably bevelled as shown.
In the modification shown in Fig. 7 the apertures are made oblong hori-
zontally.
My improvement cannot be tampered with by burglars as it is embedded within
the framework. This lock can be used on doors or elsewhere.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. The plate A, having aperture g, and casing B, composed of side plates a
and bottom plate. b, combined with cover D, having back plate d and pro-
jection h, top plate e having projection, and rod E, and a bolt F carried by
the casing.
2. The plate A, and casing B, combined with a sliding bolt B having a recess 1,
and with a spring within said recess and a sliding rod having an inclined side for
actuating said bolt.
3. The combination of the casing with a bolt sliding therein and having a pro-
jection J, the wearing side of said projection being curved, with bar I, having
an inclined edge m, to engage projection J, to move the bolt.
4. The combination of a casing and its front plate, a bolt within said casing,
and having a recess 7, a spring within said recess, a projection J on said bolt,
inclined rod to engage said projection to move the bolt and rod N.
5. The combination of a casing having a front plate, a ledge o, bolt F having a
recess, spring H in said recess, projection J on said bolt, rod I having an inclined
side, said rod having a hook shaped end to engage projection J, for the purpose
specified.
6. A casing, projection M thereon, bolt F, combined with a bar having an inclined
side to move said bolt, a projection L on said bar, and a spring between pro-
jections L and M, and a rod for moving the inclined bar.
7. A casing containing a sliding bolt, combined with a bar having an inclined
side to move said bolt, an independent spring to move said bar, and with a rod for
moving the latter.
8. A sash having a groove on its outer edge combined with a plate over said

page_text: groove and having a series of apertures to receive a bolt, said groove opening below
said plate.
9. A sash having a groove on its outer edge, combined with a plate over said
groove, said plate having a series of apertures placed close together, the contiguous
edges of said apertures being bevelled to permit a ready entrance of the bolt into
the apertures.
10. A sash having a groove on its edge, combined with a plate over said groove,
said plate being placed in a recess on said sash, said plate having a series of
apertures to receive a bolt.
11. A. sash having a groove on its edge, combined with a plate P, said plate
having a series of apertures that are oblong horizontally.
12. A metal plate for a window sash having a series of apertures placed close
together their contiguous edges being bevelled.
13. A plate for a window sash having a series of apertures that are oblong
horizontally.
14. The combination of bolt F, bar I, and rod N, having projection t, with a
plate having aperture w, said plate acting to hold said rod when it is pushed through
the aperture and turned.
15. The combination of bolt F, bar I, rod N, having projection t, and a recess
between said projection and head u, with a plate having an aperture w.
