COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 425,992, dated April 22, 1890.

Application filed July 12, 1889. Serial No. 317,274:- (McdeL) To aZZ whom it may concern.-

Be it known that I, JOSIAH J .DEAL, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Oombination-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in locks, and particularly to that class known as combination-locks ;and it consists of certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure 1 of the accompanying drawings is an elevation of the lock with a portion of the case removed, showing the interior of the look, also showing the application of the lock to a door-bolt. Fig. 2 is a perspective of the in side portions, showing the toothed wheels and disks. Fig. 3 is a plan View of the disk of a commutation-wheel and check. Fig. at is a similar view of a commutation-wheel. Fig. 5 is an elevation of the lock, the outside case partly removed, showing the interior of the lock applied as a padlock. Fig. 6 is a perspective comprising the parts of the bolt-stop.

Similar letters of reference indicate corresponding parts in all of the figures of the drawings.

A represents the body frame of the lock, and B an inside gear-supporting frame, in which the commutation-wheels O are loosely mounted. The disks D and toothed wheels E are integral, and for the purposes of this case I have shown three. These wheels are similar one to the other, each havinga peripheral disk portion a, having a notch, as Z), in the peripheral face, and side depressions, as c, and a toothed face (Z, excepting the wheel shown in Fig. 3, in. which case the notch b, as shown in Fi 3, has one of its sides cut away, forming a grade 6, extending from the bottom of said notch to the outer face of the disk portion a.

The disks D are loosely mounted on an axle-pin f, the ends of which are secured in the frame B. For each wheel or disk is provided a spring-stop g, having its inner end coiled to form an eye, through which the axlepin f is passed. The outer or free end of the spring is bent over the outer edge of the disk, the end portion resting in the notch e, of which there may be any desired number. That portion of the springbetween its ends is so kinked or bent as to form a yielding or spring portion. These stops are placed in the notches c, at difierent distances from the notch 12, as 1 2 3 a 5, which will be explained farther on. To change the combination, remove the clip 2, draw the frame 13 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 7t, journaled in the frame A The number of teeth j on pinion F for the purposes of this application will be one-third the number of teeth 7c on the wheel E. On the outer end of the shaft h is provided a turnbutton G. The pinion-shafts, as before stated, are j ournaled in the frame A, and are in po sition 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 Zm, the free ends of which are bent to engage the notches b in the disk D and a similar notch in the lock-bolt J. The energy of the spring a is exerted to hold the pawl in engagement with the disk.

To further the explanation, I will number the wheels and pinions in pairs from left to right. I11 disk No. 1 the spring-stop g is placed in notch 0 in disk 2 the stop is placed in notch 0 and in disk 3 in notch 0 The pinions are now turned to the left in their order until stopped by the contact of the stop g with the pawl I, as shown by the dotted lines in Fig. 3, and so on until all of the steps have been brought against the pawl Z. This will show the parts locked. Now, to unlock the parts, pinion 1 will be turned one revolution to bring the notch b in disk 1 under the pawl Z. Pinion 2 will be turned two revolutions to bring notch b in disk 2 under the pawl Z, and pinion 3 turned two and a half revolutions to bring its notch Z) under the pawl Z, at which instant the energy of the spring 02, one end of which is secured to the arm on 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 disks, and by so doing disengage the pawl from the locking-bolt. Having now described one of the simplest combinations, I have only to say that by changing the stops to other notches c a great number of combinations may be made. It may now be supposed that the disk shown in Fig. 3 be the central one, or number 2, in this case. To lock the parts without disturbing the combination, turn the pinion engaging that wheel to the right, when the disk will be turned to the left, and the grade 6 will raise the pawl and throw the outer end into engagement with the bolt J or post J to lock the lock 3 and to unlock, reverse the movement, letting the end of the pawl drop back into the notch. The combination may be disturbed by turning either of the pinions out of the order mentioned.

To throw the bolt J, as shown in Fig. l, a knob, as K, is provided, having a spindle or shaft P, to which an arm q is secured, said arm engaging the bolt, as shown, by which the bolt may be thrown or shut by turning the knob.

I do not limit myself to the application of my invention, as it may be used for locking the bolt in a door-lock, as the hasp or staple of a padlock.

Having thus fully described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a lock consisting, essentially, of frames A and B,

disks D, toothed wheels E, stops g, toothed turn-buttons G, and a spring-actuated pawl Z, adapted to engage a locking-bolt or hasp, substantially as described, and for the purpose set forth.

2. The combination, wit-h the removable frame B, of the disks D, having a peripheral notch, as b, side notches c, spring-stop g,having the inner end loosely secured about the axle of said disk, the outer end adapted to rest in the notches c, a toothed wheel E integral with said wheel, a toothed pinion adapted to engage the teeth of said wheel, a turn-button G and spring-pawl Z, and locking-bolt or hasp, substantially as described, and for the purpose set forth.

3. The combination, in a lock, of a series of disks, as D, peripheral notches, as b 0, one of said series of disks having one side of the notch graded, as e, side notches e, spring-stop g, toothed wheels E, a toothed pinion F to e11- gage with said wheel, aturn-button G, springpawl Z, and a locking-bolt or hasp, substantially as described, and for thepurpose set forth.

4. The combination, in a lock, of the frames A and B, disks D, stops toothed wheels E,

pinions F, turn-button G, pawl Z, locking-bolt J, and knob K, having a spindle p and arm q to engage said bolt, substantially as described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 17th day of June, A. D. 188.).
