spring-plate, 29, to the free end of which a ver-
tically-arranged pin or bolt, 30, is secured,
which passes through an aperture, 31, formed
in the said casing c', and is adapted to engage
5 with recesses 32, formed in the bar D. The
knob C' and the casing c' are adapted to slide
upon the bar D, and by removing the pin 30
and raising it against the action of the spring
29 the knob and casing may be shoved inward
io toward the lock against the cog-tumbler 12,
which, being arranged, as hereinbefore de-
scribed, in connection with the yoke 15, presses
the said yoke inward, throwing the cog-tum-
bler 9 in contact with the tumbler-plate 6 and
15 against the cylinder 4, which presses the yoke
2 outward toward the knob C and releases the
- bolt B, as hereinbefore set forth. Thus it will
be seen that the lock may be opened either
from the inside or the outside, that it has been
2c arranged to be opened by the combination, or
it may be opened from the inside without the
operation of the combination, asj ust described;
but in passing through the door upon which
this form of lock may be used in either direc-
25 tion the bell-cog may be so arranged that it
will give a signal at the turning of either the
inside or the outside knob, so that a notice
will be given to the occupants of the house,
either when a person attempts to enter the
30 house or to pass therefrom. It will also be
observed that the parts of the lock are so con-
structed that they will return to their normal
position through the medium of the yokes and
springs, as described, and for the purposes
35 specified.
The novelty and utility of my device being
obviously apparent, it is not necessary to fur-
ther enlarge upon the same herein.
It is obvious that many minor variations
40 in the construction and arrangement of parts
may be made and substituted for those shown
and described without departing in the least
from the nature and principle of my. inven-
tion.
45 I do not wish to be limited to the use I may
make of my invention, as I am aware that it
can be advantageously employed in other
places besides doors. I contemplate applying
it on tills and safes.
o50 Having thus described my invention, I
claim-
1. In a combination-lock, the combination,
with the knob C and the bar D, of the wires
w, the yoke 2, the tumbler 18, and washer 3,
55 the cylinder 4, the rack-plate 20, and the
headed pin 21, substantially as described.
2. The combination, with the bolt B, of the
guide-rod 19, encircled by a coiled spring,
S", situated in the rear thereof and in con-
60 nection therewith, the.cylinder 4, over ,which
said bolt B has movement, the tumbler-plate
6, having projections 7, and the projecting
arm b' on the bolt B, adapted to be engagedby the projections 7 on the plate 6, substan-
tially as described. 65
3. The combination, with the tumbler-
plate 6, having an aperture therein, of a cog
configuration, the cog -tumbler 9, the collar
10, the cog -tumblers 11 and '12, the yoke-
plate 15, and the bar D, substantially as de- 70
scribed.
4. The combination, with the bar D, of the
casing c', adapted to slide thereon, and the
bell-actuating cog 28, mounted on said slid-
ing casing c', substantially as described. 73
5. The combination, with the bar D, hav-
ing the recesses 32, of the sliding casing c', the
flat spring 29, connected to said casing, the
pin 30, carried by said spring, the knobs C
and C', and the intermediate mechanism de- 80
scribed, substantially as set forth.
6. The combination, with yokes 2 and 15,
the tumbler-plate 6, and the tumblers 9 and
12, of the rods 1 and 13, having movement
through the ends of the yokes, and the coiled 85
springs surrounding said rods, substantially
as described.
7. The combination, with the knobs C and
C', bar D, tumblers 18, 9, and 12, and spring-
actuated yokes 2 and 15, of the plate C', the 90
keys K, the plate 16, the rods 17, having
coiled springs S', and the wires w w, substan-
tially as described.
8. The combination, with the knobs C and
C', of the rod D, the cog-tumblers 9, 11, and 95
12, the yoke 15, the yoke 2, and the wires iw
w, substantially as described.
9. The combination, with the knob C, of the
inner face-plate, C', having the depressions
c, the keys K, the plate 16, the wires w, the Ioo
washer 3, and the yoke-plate 2, substantially
as described.
10. The combination, with the tumblers 9,
11, and 12, the collar 10, the yoke 15, of the
casing surrounding said parts having the cen- 105
tral cog-apertured seat, substantially as de-
scribed.
11. The combination, with the knobs C and
C', the bar D, the wires w, and the casing c',
of the yoke 2, washer 3, the cylinder 4, the r ro
tumbler-plate 7, the cog-tumblers 9, 11, and
12, the yoke 15, and the bolt B, substantially
as described.
12. The combination, with the plate 16,
having keys K, operating in conjunction 1i5
therewith, of the sectional cog-tumbler 12,
and the wires connecting said tumbler to the
plate 16, substantially as described.
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in 20o
presence of two witnesses.
