IMPROVEMENT IN ALARM-LOCK.
The schedule referred to in these Letters Patent and making part of the lame To all whom it may concern..-
Be it known that I, FRANK Bnnws'rnn, of Cleveland, in the county of Ouyahoga, and State of Ohio, have invented a new and useful Improvement in Alarm-Locks;
.and I do hereby declare that the following is a full, clear,
and exact description of the same, reference being had to the annexed drawings, making part of this specifi cation, in which- Figure 1 is a plan or top view of a drawer, with my improved locking-apparatus attached thereto.
Figure 2 is an elevation of the same, showing the counter, or desk to which it is attached. 7
Figure 3 is an elevation of the locking-disk, or pinwheel, and a portion of the lever for returning the pins to their position in the wheel.
Figure 4 is a central sectional elevation of the wheel,
Figure 5 is a'vertical transverse section, on line x-a: of fig. 3.
Figure 6 is a front view of the ratchet-wheel, which is secured to the rod which passes through the drawer.
Figure 7 is a transverse vertical section of the same.
Figure 8'is a plan or top View of the clock-work for giving the alarm, and
Figure 9 is an elevation of the same.
Figlu'e 10 is an elevation of the lever, for releasing the alarm-mechanism, and for returning the pins to their position, after having been displaced by eiforts to unlock the drawer upon which the lock is placed.
Corresponding letters refer to corresponding parts in the several figures.
The invention relates to alarm-locks for moneydrawers, and other analogous purposes, and is designed as an improvement upon the lock patented by A. D. Hoffmann, October 27 1868; and
It consists in combining, with the rod which passe through the drawer, and to which the alphabet is attached, a ratchet-disk,or wheel, and projections formed upon the pin-wheel, for the purpose of enabling the person having possession of the lock, to change the position of the parts, so as to enable him to unlock the drawer when the pointer upon the front of the drawer points to any chosen letter of the alphabet, and so that he can change such letters, with reference to the slot in the pin-wheel, at his pleasure.
It further consists in the construction of the lever which disengages the alarm-mechanism, and which also returns the pins in the wheel to their original position, after they have been displaced by an elfort to open the drawer upon which the lock may be placed.
A, in the drawings, represents adisk, or wheei, which 7 is provided upon its outer face with teeth, or projections, corresponding in number with the letters of the alphabet, or with the number which it is found desirable to put upon the index in front of the drawer. This disk is secured to the rod D, which extends through the drawer, from front to rear.
B B represent two projections, which are to be attached to 'the pin-wheel B, at such a distance from its or handle, having formed upon, or attached to its periphery, the letters of the alphabet, or any other characters or figures which may be desired, but which should correspond in number with the number of teeth in the wheel, upon the opposite end of the rod.
To the front of the drawer there is to be attached a pointer, which will point to the letters upon the knob.
It 'will be seen, by referring to the drawings, that the disk A is attached to the rod 0, outside of the rear end of the drawer, where it is to be held by means of a set-screw or other suitable device and, also, that the pin-wheel B is to be placed upon the same rod, with its projections pointing toward those of the disk, so that, as it is screwed into position by means of the nut,
.which' works upon a thread formed upon the extreme end of such rod, the projections B B will be .forced intov the depressions upon the disk A.
It will also be seen that there is formed, in the periphery of the pin-wheel B, a recess, through which the" bolt, or catch, which secures the drawer in its closed position, must pass, when opening such drawer. If this notch is brought to the top of the wheel, it will pass the catch, which is affixed to the counter, and permit the drawer to be opened, but if turned to any other position, will prevent the opening of said drawer.
When it is desired to arrange the drawer so as to prevent it from being opened by any one except the person in charge, some particular letter of the alphabet is selected, and it is brought directly underneath the pointer on the front of the drawer, when the slot in the pin-wheel will be in position to pass the stop, or catch, and the drawer may be opened without giving an alarm. And when it is desirable to change the letter, the nut upon the end of the rod is unscrewed, and the pin-wheel, slid back thereon, until its projections will pass those on the disk, and the knob is turned until some other letter or character is brought under the pointer, and'the nut is screwed back to its original position, when the drawer will unlock at that letter only, because the slot in the pin-wheel will be in position to pass the stop only when the particular letter upon the knob is under the pointer; and the eifect of an endeavor toreverse the drawer at any other time, will result in pressing forward one of the pins in the pin-wheel, so that, upon any attempt to turn the knob, the alarm'will be sounded,as in the case above alluded to.
D represents a lever, which has a groove, or slot in one of its ends, which corresponds in form with the slot in the pin-wheel, so that, when in the proper position, it may pass the stop with such wheel; but when an attempt is made to open the drawer, when these slots do not register, one'of the pins will be driven for ward into the slot, or groove in this lever, which, if an attempt is made to turn the knob, or handle, will come in contact with the end of such groove, and thus cause the opposite end of such lever to release the spring, which carries the clock-work, and permit the alarm to be sounded. Upon the rear side of this lever, a groove is formed, having bevelled faces, as shown at a a, into which the pins enter, after having been the means of releasing the alarm-mechanism, and by which they are returned to their original position, in the pinwheel, ready to be again pressed forward, upon any attempt to open the drawer clandestinely.
The remaining portion of the device, such as the alarm-mechanism, and the manner of attaching it to the drawer, being fully described in the patent above referred to, need not be particularly described here,
and especially so, as it forms no part of my present invention.
Having thus described my improvement,
What I claim, and desire to secure by Letters Patent, is'
1. The combination of the ratchet-wheel, or disk A, the pin-wheel, with its projections B B, and the .loose pins, with the lever D, for releasing the alarmmechanism, substantially as shown and described.
2. The arrangement of the disk, or ratchet-Wheel A, pin-wheel B, the rod to which they are secured, and index-knob, upon the opposite end of such rod.
3. The construction of the lever D, with its inclined surfaces, substantially as and for the purpose described.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
FRAN K BREWSTER.
