CLARENCE W. McNEIL, OF SAN ANTONIO, TEXAS, ASSIGNOR OF ONE-HALF TO J. B.
ARMSTRONG, OF CAMERON COUNTY, TEXAS.
LOCKING-BOLT FOR GUARDS TO OPENINGS.Specification of Letters Patent.
Patented March 31, 1908.
Application filed March 22, 1907. Serial No. 363,991.
To all whom it may concern:
Be it known that I, CLARENCE W. MCNEIL,
a citizen of the United States, residing at San
Antonio, in the county of Bexar and State of
5 Texas, have invented certain new and useful
Improvements in Locking-Bolts for Guards
to Openings, of which the following is a speci-
fication.
My invention pertains to certain and use-
10 ful improvements in locking bolts.
The object of the invention is to provide an
improved locking means which can be easily
operated and still when locked will effectually
prevent unlocking thereof.
15 With the above and other objects in view,
my invention further consists in the novel de-
tails of construction and combination of parts
to be fully herein after referred to and later
pointed out in the claims.
20 Referring to the accompanying drawings
forming a part of this specification and where-
in like numerals of reference indicate similar
parts throughout, Figure 1, is a front eleva-
tion showing my improved device applied to
25 a frame, Fig. 2, is a vertical section on line
Y-Y-of Fig. 1, Fig. 3, is a horizontal section
on line X-X-of Fig. 2, Fig. 4, is an enlarged
detail view showing two of the vertical rods
and one of the end bars with the locking
30 means applied thereto, and Fig. 5, is a view
of the inner face of the end bar.
In showing my invention in use I have dis-
closed a special form of window guard with
which I use the invention, and in referring
35 thereto in the drawings, 1, designates a win-
dow frame formed at its ends with vertical
pockets 2, the cover for the. pockets to the
right of Fig. 1, being shown removed. At
the top and bottom of each pocket there is
40 secured a metal plate 3, provided with aper-
tures through which pass reduced ends 4, of a
vertical rod 5, which rod is at its lower end
surrounded by a coil spring 6, secured at its
upper end to said rod and at its lower end
45 projecting in an aperture provided therefor in
the lower plate as at 7. Thus the guard is
automatically wound about rod 5, as will be
now pointed out.
Ledge 8 of the window sill and top 9 are
50 each provided with a longitudinal way 10, in
which travel and are guided a series of steel
rods 11, arranged in spaced relation as shown
and connected by a series of flexible chains12. These chains comprise two spaced links
13, and connecting links 14, each of which is 55
penetrated by one of the rods 11, which there-
by serves to provide the pivotal point for said
links. The end bars 15, are connected to the
links 13, 13, of the adjacent rod by a short
section of chain 16, which has a link 17, se- 60
cured therebetween and penetrated by said
rod, and a connection 18, secured to member
19, of the end bar 15. This end bar coin-
prises two movable members 19, 20, connect-
ed by the pin and slot connection 21, 21', and 65
22, these members being designed for simul-
taneous operation in opposed directions to
thereby enter seats 23, 24, at the top and
bottom of the window frame. This move-
ment of members 19, 20, is effected by an op- 70
erating lever 25, of Z-shape having its inner
end secured to pin or rivet 21, of the pin and
slot connection between the bars and having
its outer end pivoted by a rivet 26, to the off-
set end 27, of a bar which at its opposite end 75
is secured to pin or rivet 21', so as to operate
the latter therewith. It will thus be ob-
served that by exerting downward pull on one
of the operating levers and an upward pull on
the other of the levers, the respective locking 80
members of the .end bars will be forced away
from one another until the levers are at right
angles to the bars at which time the locking
members at their ends occupy their respec-
tive seats 23. When said levers are in locked 85
position they aline with one another and are
so related that a padlock may be passed
through aperture 28, of each lever, especially
provided therefor, which will effectually pre-
vent movement of either lever. 90
Having thus fully described my invention,
what I claim as new and desire to secure by
Letters Patent is:-
1. In combination with a guard or the like,
means for locking the same composed of two 95
movable members, means whereby said mem-
bers may have a sliding movement, a bar
connected to one of the members, and an op-
erating lever connected to said bar and to the
other member whereby when said lever is op- 100
erated said members will be actuated to-
wards and away from one another in unison.
2. In combination with a guard or the like,
means for locking the same composed of two
movable members having a pair of pin and 105
slot connections, therebetween, a bar pivot-No. 883,471.
