Improvements in Locks.
I JOSIAH J. DEAL, Manufacturer, 176 East Fourth Street, Canton, County of
Stark, State of Ohio, United States of America, 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:-
This invention relates to improvements in locks, and particularly to that class
known as combination locks, and consists of certain features of construction and
combination of parts; as will be hereinafter described and pointed out in the
claims.
Fig. 1 of the accompanying drawing is an elevation of the lock, with a portion
of the case removed, showing the interior of the lock, also showing the application
of the lock to a door bolt.
Fig. 2 is a perspective of the inside portions, showing the toothed wheels and
discs.
Fig. 3 is a plan view of the disc of a commutation wheel and check.
Fig. 4 is a similar view of a commutation wheel.
Fig. 5 is an elevation of a lock, the outside case, partly removed, showing the
interior of the lock applied as a pad-lock.
Fig. 6 is a perspective comprising the parts of the bolt stop.
A represents the body frame of the lock and B an inside gear supporting frame,
in which the commutation wheels C are loosely mounted.
The discs D and toothed wheels E are integral, and for the purposes of this
case, three are shown. These wheels are similar one to the other, each having a
peripheral disc portion a, having a notch, as b, in the peripheral face, and side
depressions, as c, and a toothed face_d, excepting the wheel shown in Fig. 3, in
which case, the notch b, as shown in Fig. 3, has one of its sides cut away, forming
a grade e, extending from the bottom of said notch to the outer face of the dise
portion a.
The disc D are loosely mounted on an axle pin f, the ends of which are secured in
the frame B; for each wheel or disc is provided a spring stop g, having its inner
end coiled to form an eye, through which the axle pin f is passed, the outer or free
end of the spring is bent over the outer edge of the disc, the end portion resting in
the notch c, of which there may be any desired number. That portion of the spring
between its ends is so kinked or bent, as to form a yielding or spring portion. These
stops are placed in the notches c at different distances from the notch b, as 1, 2, 3, 4, 5,
which will be explained further on. To change the combination, remove the clip z,
draw the frame B out of the case or frame A, when the parts will be exposed, and
the stops g changed, as desired.
To rotate the toothed wheel D, there is provided a corresponding number of
pinions F, mounted on shafts h journalled in the frame A; the number of teeth on
pinion F for the purposes of this application, will be one-third the number of
teeth on the wheel E. On the outer end of the shaft h, is provided a turn button G ;
the pinion shafts, as before stated, are journalled in the frame A, and are in position
substantially as shown. The frame B, with the wheels E thereon, is passed into the
frame A, to a point at which the teeth of the wheels E will engage the teeth of the
pinion F.
A bell-crank spring-actuated pawl is provided, which may be in one or more parts,
as l, m, the free ends of which are bent to engage the notches in the disc D, and a
similar notch in the lock bolt J; the energy of the spring n is exerted, to hold the
pawl in engagement with the disc.
To further the explanation, the wheels and pinions are numbered in pairs from
left to right. In disc No. 1, the spring stop y is placed in notch ; in disc 2,

page_text: with the
the stop is placed in notch e; and in disc 3, in notch e; the pinions are now
turned to the left in their order, until stopped by the contact of the stop
pawl, as shewn by lotted lines in Fig. 3, and so on until all of the stops have
been brought against the pawl ; this will shew the parts locked. Now to unlock
the parts, pinion 1 will be turned one revolution, to bring the notch bin disc No. 1
under the pawl. 1; pinion 2 will be turned two rovolutions, to bring notch bin
disc 2 under the pawl ; and pinion 3, turned two and a half revolutions, to bring
its notch under the pawl 7, at which instant, the energy of the spring n, one end of
which is secured to the arm m of the same, and the other to the frame, will draw the
end of the pawl into notches b, as now arranged in line across the discs, and by
so doing, disengage the pawl from the locking bolt.
The above described arrangement is one of the simplest combinations, but by
changing the stops to other notches c, a great number of combinations may be
made.
It may now be supposed that the disc shewn in Figure 3 be the central one, or
number 2; in this case, to lock the parts without distributing the combination, turn the
pinion engaging that wheel to the right a distance, the disc will be turned to the left ;
the grade e will raise the pawl, and throw the outer end into engagement with the
bolt J, or part J, to lock the lock, and to unlock, a reverse movement letting the end
of the pawl drop back into the notch. The combination may be distributed by turning
either of the pinions out of the order mentioned.
To throw the bolt J, as shewn in Figure 1, a knob, as K, is provided having a
spindle or shaft P, to which an arm is secured, said arm engaging the bolt, as
shewn, by which the bolt may be thrown or shut by turning the knob.
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. As a new article of manufacture, a lock consisting essentially of frames A
and B, discs D, toothed wheels E, stops g, toothed pinions F, adapted to engage the
wheels E, turn buttons G, and a spring-actuated pawl 7, adapted to engage a lock
bolt or hasp, substantially as set forth.
2. In combination with the removable frame B, the discs D, having a peripheral
notch, as b, side notches c, spring stop y, having the inner end loosely secured about
the axle of said disc, the outer end adapted to rest in the end of said notches c, a
tooth wheel E, integral with said wheel, a toothed pinion adapted to engage the teeth
of said wheel, a turn button G, and spring pawl 1, and lock bolt, or hasp, substan-
tially as set forth.
3. The combination, in a lock, of a series of discs, as D, peripheral notches, as b, c,
one of said series of discs having one side of the notch graded, as e, side notches e,
spring stop g, toothed wheels E, a toothed pinion F to engage with said wheel, a turn
button G, spring pawl 1, and locking bolt or hasp, substantially as set forth.
4. The combination, in a lock, of the frames A and B, discs D, stops g, toothed
wheels E, pinions F, turn button G, pawl 1, locking bolt J, and knob K, having a
spindle p and arm to engage said bolt, substantially as set forth.
