the frame, as d, preferably metal-lined, to re-
ceive the bolts at such points as it is desired
to lock the window.
In order to withdrawor unlock thebolt, the
5 upwardly-projecting end of the cam is carried
up until it bears.on the part b' of the bolt,
from which it will be evident that as the cam
is moved by the annular handle its action up-
on the crank-arm of the bolt will cause the
io latter to be withdrawn from the orifice in the
frame and allow the window to be raised or
lowered without difficulty.
It will be apparent that this window-fasten-
ing device may be applied to other than car-
15 windows, as its construction allows of its ap-
plication to almost any sliding sash.
Having thus described myinvention, I claim
as new and desire to secure byLetters Patent
the following:
20 1. As an improvement in car-window locks,
the sliding crank-sharyd spring actuated bolt
b for locking the window, in combination with
the oscillating cam a, acting upon the bolt to
unlock it, said cam having a lateral arm with
a spring-guide hinged thereto, a spring sur- 25
rounding the guide, and means for swinging
the cam and thus retracting the bolt, all ar-
ranged and operating substantially as speci-
fied.
2. In a car-window lock, the bolt and cam 30
support thrown outward by springs, in com-
bination with the annular handle, and con-
nections for withdrawing the bolt and cam
arranged and operating in the manner shown
and described. 35
In testimony that I claim the above as my
invention I hereunto affix my signature in the
presence of two witnesses.
