Application filed August 7, 1884. (Model.)

To all whom it mag concern.-

Be it known that I, GEORGE A. COLTON,

a citizen of the United States, residing at the line X of Fig. 4.

tion of the door or drawer to which the lock is applied. Fig. 3 is a face view of the lock with the pull removed and the bolt projected. Fig. 4 is a face view with the pull and faceplateremovcd. Fig. 5 is a vertical section on Fig. 6 is a vertical section on the line Y of said figure, looking in the direction indicated by the arrows. Fig. 7 is a plan of one of the tumblers. Fig. 8 is a plan of the latch-operating tumbler or bar; and Fig. 9 is a plan of thelock-bolt, thelatchoperating tumbler or bar being shown in dotted lines. Fig. 10 is a perspective and asection of one of the permutation-keys.

Like letters refer to like parts in all of the figures. r

The object of this invention is to provide a lock having a pull or handle portion simi lar to a drawer-pull for opening and closing a door or drawer, which pull shall be adapted to ring an alarm when operated independently of certain permutation-keys, spindles, or latches, so that persons tampering with the lock without having knowledge of itsconstruction or the arrangement of its parts shall cause an alarm to be sounded, while-per sons conversant with its construction and arrangement may open or close the door or drawer without sounding such an alarm, the above objects ,to be gained by such mechanical devices and by a lock so constructed that it may be readily attached to any door or drawer as are ordinary locks.

Other objects and advantages will appear in the following description.

A represents a door or drawer face, or that portion thereof to which a lock is ordinarily secured.

A B represents a base-plate provided with guides B, within which the bolt 0 of thelock 'propcrslides or reciprocates. The base-plate is also provided with a flange, B", designed to be let into the edge of the door or drawer front, as is usual. The base-plate is also provided with standards B to which the pull D is pivoted at each of its ends by means of screws or pintles D. (See Fig. 6.) The base-plate B is also provided with standards B*, arranged to form in connection with the standards B means for maintaining a series of tumblers, E, at a right angle to the bolt 0, and it is also provided with a hub or perforated boss, 13, for the reception of an ordinary'cylindrical tumbler-lock,f, the body of which is provided with ahook, f, adaptedto be turned into and out of connection with recesses f formed in the ends of the tumblers for the purpose of retaining the said tumblers against longitudinal movement when it is desired to permanently look a drawer or door.

By reference to Fig. 9 it will be seen that the bolt 0 comprises a rectangular body provided with a standard, 0, and that the body is cut away on one side, as at G, to receive an arm, D projecting from one end of the pull D. Said arm D is therefore capable of raising the bolt when the latch is withdrawn from a lug, B, and the pull is lowered or pushed toward the face-plate. \Vithin the body of the bolt is arranged a latch .0, pivoted at 0* near the lower end of the bolt, and provided with a projecting lug, G The under surface of the latch is cut away, as shown by dotted lines, Fig. 4, so as to pass overa lug, B, (also shown in dotted lines in said figure,) which lug is formed on or cast as a part of the base-plate B. Now it will readily be seen that when the latch (J is vertical the bolt 0 cannot be drawn into the case by reason of the upper end of said latch coming in contact with the lug B, so that in order to unlock or withdraw the bolt within the case the latch G must be moved to the left, so that it will project into the recess When this is done, the upper end of the I to permit of its being forced against the bell latch will be struck by the arm D of the pull, and the bolt may by said pull be withdrawn into the case, provided that the standard 0 meets with no obstruction. Obstructions against such a movement of the bolt, in addition to that which the latch O causes when not moved to the left, as just described, are provided in the tumblers E, one of which is shown in full lines in Fig. 7, and all of which are pro vided with slots E, each one being brought in line with the others to permit the entrance of the standard 0, so that the bolt may be with drawn. Each tumbler of the series is provided with an opening, E", terminating at one end in a slanting wall, E, and the opening in each tumbler of the series is somewhat shorter than that of the preceding tumbler, as shown by dotted lines, Fig. 7. Each of the tumblers is also provided with a projecting lug, Ff, having a perforation therein, through which one arm of the spring is projected, the other arm resting on the base-plate B, while the body ofthe spring is coiled about a pin or stud, E, arranged parallel with the base.

The latch-operating tumbler or bar F, Fig. 8, is provided with a series of openings, F, the transverse walls F of which are arranged diagonally and opposite to the walls E in the openings of the tumblers, so that when the tumblers are arranged aboy e the latch-bar these oppositely-inclined walls furnish means which, in connection with a suitable device hereinafter described, reciprocate the tumblers and latch-bar in opposite directions, while the springs E return the tumblers E, and a similar spring, F serves to return the latch-bar to its normal position. The latch-bar is slotted, as at F, for the reception of the lug C on the latch 0 so that as the bar is drawn to the left, as herein arranged, the said latch is withdrawn into the recess 0 of the bolt for the purpose above described.

At the opposite end of the bar to that in which the slot F is formed is aprojecting arm, F, the object of which is to move a belllever, G, Fig. 5, out of the path which it takes when it operates the alarm. Said. lever G is pivoted to and so as to swing lengthwise of the pull, it being attached to the pull at G, and beneath or behind a short arm, G cast upon the pull. The oscillations of the belllever are such in extent that at no time does it swing entirely free from the arm G so that When otherwise uninfiuenced the lever oscillates with the pull and its arm G in a vertical plane. The spring F rests against the lever G, so as to hold it normally against the proj ection F of the latch-bar F, so that when said latch-bar is reciprocated longitudinally and to the left, the said lever is carried with it, and is caused to escape the hammer-lever H, and thus prevent the sounding of the alarm or bell I. The hammer-lever H is provided with an inclined lug, H, against which in its downward passage the lever G rides, so as to depress the hammer (shown in dotted lines) and by means of a spring, as is usual in alarms of this class. Now it will be seen that the simple operation of drawing the pull away from the face-plate serves to ring the bell, and that without the proper manipulation of the permutation latches or spindles the alarm will be sounded at each of such motions of the pull.

Referring to Fig. 10, J represents one of the permutation latches, keys, or spindles removed, and it comprises the T-head J, having a slight projection, J", a body portion, J substantially cylindrical for a portion of its length, and enlarged at J, and is shaped flat upon its side, as at J and substantially V- shaped at its opposite side, and is provided with an encircling flange, J, and the flat.

end J Taken in connection with the openings in the tumblers and the latch-bar, which have oppositely arranged inclined walls, as described, it will be noticed that when the V- shaped sides of the latches, keys, or spindles J are arranged in saidopenings so as to project upwardly, by raising the ends J of said latches, keys, or spindles, they will have a tendency to act like a wedge against the said inclined walls, so that each of the tumblers and the latch-bar may, by the operation of one or more properly-arranged latches, keys, or spindles, be reciprocated in opposite directions to a proper distance to bring their slots E and the half-slot F in the drawbar all in line with each other, so that the lug C of the bolt may enter the same, and the bolt be withdrawn into the case, and the drawer or door thus unlocked,while the opposite sides, J of the latches, being flat and projecting entirely from one side only of its body portion, act to manipulate the tumblers only, and fail to reciprocate the latch-bar, and they are inoperative, and it therefore follows that freedom of selection and arrangement of operative permutation latches, keys, or spindles is secured, so that by turning one or more of the same up or down the combination of the lock may be changed to suit the user, whereby he completely controls the look, so that the use of the cylindrical tumbler-lock f is not essential.

In cases where several persons are coir versant with the combination of the permutation latches, keys, or spindles, as during business hours, the lock f becomes of use to place the control of the lock entirely with one person in or out of business hoursthat is, the person carrying the key to the same. Therefore I prefer to retain the lock f, although other features of my invention are not at all dependent thereon.

Referring to Figs. 2 and 6, K represents an opening in the base-plate, which is closed by means of a longitudinally-grooved cap, K, having depressions K along the edges of the grooves to receive the projections J on the T- heads on the latches, keys, or spindles J, whereby when the T-heads are inserted in the grooves they assist in controlling the move maining portion of the head projects across the joint between the base and the plate, where by the plate is retained within the base.

For the purpose of facilitating theintroduction and removal of the latches, keys, or spindles, (such removal not being necessary to change the combination of the locl it is necessary to merely remove the plate K from the base and the cap while the door or drawer is open, and to remove the latches, keys, or spindles by simply turning the T-heads to occupy a vertical position in order that they may be drawn through vertical slots (not shown) formed in the back piece and in line with the openings through the tumblers and the latchbar F, so that when so turned the latches, keys, or spindles may be completely withdrawn from the lock. The latches may be reversed to bring either its V-shaped or flat side uppermost and replaced, when the plate is again placed upon the base and secured in positior,as described. The combination may be changed by removing the plate K and turning the latches as described.

I do not wish to be understood as limiting my invention to the exact details of construction herein shown, as they may be altered in many minor respects by persons skilled in the manufacture of locks without departing from the spirit of my invention.

The arrangement of the bolt proper and of the latch-bar and tumblers at a right angle to each other renders the vertical pivotal movement of the drawer-pull available to operate the bolt of the lock proper, whileat the same time such arrangement of the tumblers and latch-bar relative to the bolt allows a vertical movement to the permutation-latches to produce a horizontal movement of the parts with which they come in contact and make the necessary mechanical preparations in thelock for the vertical reciprocation of the bolt.

L represents the cap of the lock, which is secured in position by screws L, passing through the base-plate and threaded into the cap,and by screws entering lugs B, after passing through the flange projecting inwardly from the lower edge of the cap, said latter screws not being shown, and the flange being shown at U, Fig. 6.) This cap is provided with T slots L, Fig. 3, to receive the flat end of .the permutationkeys, the narrow portions of said slots embracing a portion of the key outside of their flanges J".

To take the lock apart, the screws L are first removed and then the screws from the flanges L ,and the cap is drawn downwardly and withdrawn from the case, the flat ends of the permutation latches passing through the heads of the T slots in the cap. The pivots of the pull are now exppsed and removable, and the lock is in the condition shown in Fig. 4. \Vhen the cap is in place, the flanges of the latches are inside of the cap.

' It is evident that any form of lock may be used in place of the lock f, and that the hub or boss B may be formed as a part of the cap L. So also may any well-known electric alarm be substituted for-the bell-alarm herein shown, so that tampering with the lock may be indicated at a distance therefrom, and bolts having other than a reciprocating movement may be substituted for bolt 0, and be operated by the latclrbar F and by means of aninterposed pivoted or beltcrank lever, as commonly used a in lock structures.

Other changes within the skill of locksmiths may-be made without departing from the spirit of my invention.
