the same is to be performed, to par
the following statement :-
My invention has relation to a combined sash lift and lock and consists in the
novel arrangement and combination of parts more particularly described in the
Specification and set out in the claims.
In the drawings,
Fig. 1 is a front elevation of a window with parts broken away showing my
invention applied thereto;
Fig. 2 is a rear elevation of my invention showing the bolt in connection with
the rack which is fixed to one side of the window frame;
Fig. 3 is a side elevation of my invention;
Fig. 4 is a vertical transverse section of the same taken on the line x-x of
Fig. 2;
Fig. 5 is a perspective view of the right-angular lever employed in carrying out
my invention; and
Fig. 6 is a perspective view of a spring which I also employ.
Referring to the drawings, 1 represents a plate which is fixed to the lower rail 2
of the window sash 3 at the middle thereof and is fixed thereto by screws or other
like devices, premising however that a suitable space is cut in said rail for receiving
the several parts carried by and attached to the rear surface of said plate.
Referring again to the plate 1, 4 represents two lugs which are formed on the rear
surface thereof, and on either side of an opening 5 formed in said plate. 6 repre-
sents a thumb latch which projects a suitable distance on either side of the said
plate, and is movably secured to the lugs 4 intermediate of its length by a pivot 7
passing through the said lugs and latch. Formed also with the plate 1 and located
on the rear surface thereof is a rounded projection 8 which is received by the
tubular extension 9 of the right angular arm 10 of the lock, as best shown in
Fig. 4. After the arm 10 has been placed in position as shown in Fig. 4, the end
of the said rounded projection is flattened thereby holding the right angular arm
loosely to the plate 1, the tubular projection 9 acting to keep the said arm a
suitable distance from the plate 1. The arm 10 and its parts as shown in Fig. 5
is cast complete in one piece and in said figure, 11 represents a hook formed on the
depending extension 12 of the same, and when the said arm is in its proper position
the hook will be adjacent to the rear surface of the plate 1 but not in contact with
the same, as shown in Fig. 3. The horizontal extension 13 of said arm normally
rests upon the rear end of the latch 6 and is always in contact with the same,
whereby when the forward end of the said latch is depressed, the said arm will be
operated and retract the bolt 14 and free the same from its engagement with the
rack bar 15 as best shown in Fig. 2. In order to dispeuse with the removable
pivot, I form on the lower end of the extension 12 of the arm 10 a rounded pro-
jection 16 which projects therefrom in opposite direction to the hook 11, and is
passed through an opening formed in one end of the bolt 14, the same being loosely
united by rivetting.
17 represents a coiled spring the shape of which can be
better seen by referring to Figure 6, and when located in its proper position, the
coils 18 thereof encircle the tubular extension 9 of the arm 10; and the arm 19
of said spring bears against one of the lugs 4 of the casting or plate 1, and its
opposite or longer arm 20 is passed over the hook 11 formed on the extension 12
of the arm 10, whereby the said arm 10 is caused to assume its normal position as

shown in Fig. 2 after the same has been operated by the thumb latch 6 for
retracting the bolt 14.
In order to accommodate the bolt 14 within the lower rail 2 of the sash, I form
in the said rail a horizontal rounded opening 21 the size of which is such as to
admit the said bolt freely, the opposite or free end of the said bolt projecting a
suitable distance beyond the edge of the sash in order to engage with the teeth 22
formed on the rack bar 15, whereby the window is held in any desired elevated
position. In order to release the bolt when it is desirable to close the window the
forward end of the latch is depressed causing the bolt to be retracted and the end
thereof freed from engagement with the teeth of the rack bar. Formed with the
plate on the front surface thereof immediately below the thumb latch and in
close proximity thereto is a lift 23 for receiving the forefinger of the hand as
best shown in Fig. 1, in which instance the thumb may be used for depressing the
latch.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
1. A combined sash lift and lock having a right-angular arm, a bolt operated by
the same, a hook formed on the depending extension of said arm, a tubular pro-
jection also formed on said arm and a coiled spring encircling the said tubular
projection one arm of which is adapted to be received by the hook carried by the
angular arm, substantially as set forth.
2. In combination with the fixed plate, a rounded extension 8 formed thereon, a
right-angular arm, a tubular projection 9 formed on the said arm aud adapted to
receive said rounded projection lugs 4 formed on the said plate, a latch 6 passing
through an opening 5 formed in the plate and pivotally attached to said lugs, a
coiled spring encircling the tubular projection 9, one arm of which bears against
one of said lugs 4, and the opposite arm removably attached to the depending
extension 12 of said arm 10, and a bolt one end of which is removably attached to
said depending extension, substantially as set forth.
