COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No, 408,355, dated August 6, 1889. Application illed April l1, 1889. Serial No. 306,851. (No model.)

To a/ZZ whom, 15 may concern:

Be it known that I, ARTHUR R. PECK, acitizen of the United States, residing at Cortland, in the county of Cortland and State of New York, have invented certain new and useful Improvements in Combination e Locks for Drawers 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such Aas will enable others skilled in. the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to certainA improvements in combination-locks for money tills or drawers, though it may be applied to other purposes, and has for its object to simplify the construction and to permit of the ready changing of the combination by reversing' the tumblers of the lock as may be desired, and to provide for the retraction or disengagement of the lockingbolt from the drawer bythe manipulation of one or more keys; and to these ends my invention consists in the combination of parts and their novel construetion, as will appear from the following' description, and more particularly pointed out in the claims and the accompanying drawings, in which- Figure 1 is a sectional elevation of Va desk and its money drawer or till embodying my invention. Fig. 2 is a partly-broken away cross-sectional view taken on the line a of Fig. 1. Fig. 3 is a similar view taken on the line 'y y of Fig. l. Fig. 4 is an enlarged detail perspective view more especially of the tumbler mechanism. Fig. 5 is a detail plan View of the locking-bolt and its actuating-lever. Fig. (i is a sectional view thereof, taken on the line .c z of Fig. 5. Fig. 7 is a detail perspective view of wthe same. Fig. 8 is a slightly-enlarged perspective of one of the detached tumblers. Fig. 9 is a similar view of the retaining and releasing oscillating bar. Fig. 10 is a transverse section thereof. Fig. 11 is a perspective view of part of the desk and drawer, showing the position of the keys. Fig. 12 is a slight modification of my invention, taken on line a: ce of Fig. l. Fig. 13 is also a slight modification thereof, taken at the same point as Fig. l2. Fig. 14 is a detail,

broken away, showing the drawer with a plate thereon, as disclosed in Fig. 1 3; and Fig. 15is a perspective View more particularly of the drawer or till, employing therewith a modied form of spring.

Iiike letters of reference refer to corresponding parts in each ligure of the drawings.

In my invention I employ a cash-desk Ain connection with a money till or drawer B, both in their general outline of ordinary construetion. I place on the back end of the drawer or till B a buffer or follower b, which is suitably held in position to slide between the cleats on extensions of the drawer cleats or ways. This buffer or follower has applied tb it a spring a, which is compressed as the drawer or till is moved inward against the follower h, and when the drawer is unlocked the recoil action of the spring will automatically throw or project the drawer outward to a limited extent. l

A bracket or frame, preferably of east metal, is secured upon the inside of the desk A. This bracket is substantially rectangular in form, having a securing or side plate C, by which it is attached to the side of the desk, and an end plate D, having an open slot d in the end, projecting from the side plate, with an arm d', extending at right angles thereto and away from the bracket. At the other end of the side plate C there is an end plate F., provided with a closed slot c. "he outer portion of this plate is re-enforeed or thickened on the outside to form a sleeve e', which is partially cut away or open. Between the end plates D and E there is a cross-bar c, which is formed integral with the plates at near their lower edges and extends from one to the other, and serves as a floor for parts of the lock, hereinafter described. A series of rocking tumblers F are east or otherwise formed in rectangular blocks of about one inch in length, having near their head ends a sleeve with a projecting hub f, through which a journal or shaft G is passed. The ends of the shaft are secured in the plates D and F. near the side plate C, and hold the inner ends of the tumblers, while their outer ends rest upon the cross-bare of the bracket. The opposite ends of the tumblers F are provided with recesses or notches g on one side IOO of the center of their faces, each ofwhich has one inwardly-inclined wall from the end toward Vthe center and one wall straight or parallel to the outside of the tumblers, which in cross-section gives the recesses a dovetailed appearance. There is a series of these tumblers F-in the present instance five in number-which are reversible upon the shaft G, to form a great number of combinations by bringing the end recesses g in or out of alignment with each other, as desired, when their notched ends rest upon the cross-bar c. Vhen the tumblers are turned to bring the notches g downward or below the center of their ends, the inclined wall is on the upper side of the notch, so that when the tumblers are Arocked upon the shaft G by means of spring pushbuttons f in the side of the desk and their outer end thrown upward against a stop-plate the inclined walls of the notches willv be on the same plane and register with the straight walls of the notches in the adjoining` tumblers that `are on the bar in a reverse position.

An oscillating bar H, somewhat rectangular in shape, is formed of two plates of metal united by a narrow bar welded between them at one edge; or, if desired, the entire bar may be cast in one piece. The lower plate h of this bar extends to the outer end of the arm CZ of the frame or bracket, where it is pivoted, and its body oscillates in the slots d and e of the end plates and works into and out of the notches g of the tumblers, while its free end extends through the slot e, and is provided with a journal h at one side of its end. The upper plate I of the bar is somewhat wider than the lower plate and of just sufficient length to extend over the tops of the end plates D and E, and serves asa stop to limit the extent of the upward throw of the tumblers F as their notches are brought into position to register one with the other. The bar fz', uniting the plates 7L and I, is of a length just sufficient to slide back and forth between the end plates D and E as the bar H is operated.

The partially cut-away or opened sleeve e in the re-enforced end plate Eof the frame or bracket is provided with a vertical lockingbolt J, which has an oblique recess j in one side of its upper portion. Within this recess there is pivoted one end of a link K, that limits the movement of the bolt. The other end of the link has a bearing that receives and holds the journal h of the bar H as it extends through the slot of the end plate. As the bolt J is operated by a spring pushbutton 7c from the top of the desk, the link K throws the oscillating bar H toward the tumblers and the edge of the plate 7L into their recesses or notches, when they are brought into position to register with each other. The bar H is drawn back from the tumblers by the link K in the upward movement of the boltJ caused by the action of a spring, hereinafter described.

L represents a cast-metal shoe, which is secured to the inside bottom of the desk underneath the bracket. This shoe has side plates Z Z at one end, between which a lever M is pivoted at m. The arm of' the lever eX- tends to the opposite end of the shoe from the vertical plates where it comes in contact with the end of the bolt J of the bracket, which rests upon it. Underneath the leverarm there is a spring N, which rests on the base of the shoe and holds the arm in a raised position. A portion of the side plate l of the shoe has an outwardly-bulging side, forming a semicircular recess n on its inner side, facing the plate l. Within this recess there is a bolt O, that extends down through a sleeve P of the shoe-casting that passes through the floor of the desk.l The lower end of the bolt forms a tooth o, which engages a recess or notch p in the top edge of the till or drawer B to effect the locking of the drawer. This tooth is beveled upon its lower forward edge to permit the rear edge of the drawer to readily pass under it in pushing or sliding the latter into the desk. The rear side of the tooth is perpendicular and faces a corresponding end wall of the notch or recess p in the top edge of the drawer or till when the drawer has been pushed in to its farthest limit to prevent the outward movement of the drawer until the tooth of the bolt has been retracted or withdrawn from the notch or recess.

The inner side of the upper portion of th-e bolt O is notched at Q to near one-third of the diameter for the loose reception of one side of the lever M, the other side of thelever resting against the vertical plate l. As the lever is rocked upon its pivot by means of the spring push-button .1c on the top of the desk striking the upper end of the bar J, which rests upon the lever M, the end of the lever between the vertical side plates of the shoe moves up and down, carrying with it the bolt O and locks or unlocks the drawer or till, as desired. As shown in Figs. 2 and t, the vertical locking-bolts J and O are set on the inner edge of the lock at Some distance from the side of the desk, requiring the till or drawer B to be set in from the edge of the desk to conform to the lock.

If desired, the end plate E may be made of a uniform thickness with the partially-opened or cut-away sleeve e cast in a separate piece, as shown in Fig. 12, so that it can be secured to either end of the plate E by screws or other means. When made in this form and it is desired to so place the lock as to have the bolts register with adrawer whose edge is near the wall or side of the desk, the sleeve c is secured to the plate E in a reverse position, so that the open or cut-away part of the sleeve is downward, toV enable the working of the link K, which is pivoted in a recess in the lower portion of the bolt J.

Vhile I prefer to use the shoe L, havingthe lever M therein, in connection with my im- IOO IIO

lIO

proved combination-lock proper, I do not, however, confine myself to this combination, as the bolt J may be extended downward and take into the drawer and supply the place of the shoe and lever, as shown in Fig. 13. In this modified construction the coil-spring N is placed around the bolt J, with its lower end resting upon the iioor of the desk, while its upper end is held under a pin q through the bolt, which presses the spring downward and the coils together as the bolt is thrown down, and when released raises the bolt to its normal position. The downwardly-eXtended bolt in this instance is made to project somewhat below the top of the drawer or till and at one side to come in contact with a plate R, secured to the top and projecting outwardly over the side of the drawer. This plate also extends at some distance in the rear of the drawer to form a hold for the bolt when the drawer is pulled out beyond the bolt.

In the outer side of the plate R there is a notch or recess p corresponding with the one hereinbefore described in the top of the edge of the drawer for the reception of about onehalf of the diameter of the bolt J, which works up and down therein. Then the bolt is raised by the spring N and is in its normal position, it iills the notch in the plate R and holds the drawer in a stationaryT position 5 but when pressed down by the push-button 7c the requis site distance admitted by the link K, acting upon the locking-bar Il in the notches of the tumblers, a notch o' in the bolt receives the edge of the plate R, enabling it to freely slide through the notch, when the spring a automatically throws the drawer out to view. As the draweris slid into place, as the notch p in the plate R receives the bolt to the depth of the notch r, the bolt is released and the contracted coil-spring' il throws the bolt upward into its normal position, Iilling the notch in the plate and locking the drawer within the case.

lVhile I have shown a coil-spring in Fig. l for expellingor throwing the drawer outwhen released, l do not wish to confine myself to this particularform of spring', as a leaf-sprin g may be used, as shown in Fig. l5, or any other well-known kind of springthat will accomplish the same purpose.

In operation the hand is placed upon the desk with the thumb on the top push-button 7a and the lingers on the side buttons f', representin g the tumblers F, having their n otlches g turned downward, these being in the present instance the end ones, as shown in Fig. 4. As the buttons f are pressed inwardly, striking the lower part of the heads of the tumblers, rockin g them upon the journal G, the notched ends are raised until they strike the upper plate I of the bar H, when they will register with the notches in the tumblers that remain unmoved. The button 7i; is then pressed down, carrying the bolt J,

which through its link K moves the oscillating bar I-l into the registering notches of the tumblers a sufticient distance to permit the bolt to pass down upon and carry with it the lever M, which withdraws the bolt from and releases the drawer, which is automatically thrown out by the spring a in the rear.

The drawer is replaced by sliding it in against the beveled tooth o when sufficient pressure is brought to bear to overcome the tension of the spring' N, when the bolt O is raised and slides into the notch in the drawer, locking it in place.

Having thus fully described my invention, that whichl claim as new, and desire to secure by Letters Patent of the United States, is-
