DRAW ER LOCK;

sr'EoIFIcATfoN forming part of Letters Patent No. 732,971, dated July 7, 1903.

Application died December 2,1902. Serial No. 133,561. (No model.)

' citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Drawer-Locks, of which the following is a specification.

Myinvention relates to drawer-locks of a class wherein the turning of a single key or the movement of a single bolt serves to look a plurality of drawers, shelves," or the like simultaneously; and its novelty consists in the construction and adaptation of the parts,

as will be more particularly hereinafter pointed out.

i In the drawings, Figure 1 is a front elevation of a series of drawers arranged in a frame and provided with my multiple lock, the looking device being shown in dotted outline below and in section above, the partsconcealing the latter being cut away to display it and the drawers being shown locked. Fig. 2 is a similar View showing the drawers unlocked. Fig. 3 is a central vertical transverse section of a drawer and adjacent parts, showing it unlocked. Fig. at is a. front elevation, partiallyin section, showing a modification of the locking device; and Fig. 5 is a transverse vertical section through the lock, showing its bolt lifted upward.

In the drawings, 4., 5, 6, and 7 are drawers arranged one above the other in a suitable frame, consisting of vertical side panels 8, horizontal partitions 8 .8 8, dad, between the drawers, a bottom 9, top 9 and a suitable back. (Not shown.) The lowermost drawer is provided with a lock and key of any improved form, provided the lock is of such a. construction that its bolt 40 projects upwardly to lock the drawer and is retracted to unlock it. In Figs. 2 and 4 the front part of the drawer is cut away to show the detail of the look. A recess 11 is cut away from the lower side of the horizontal partition 8 immediately above the lower drawer 4 and is adapted toreceive the upwardly-projecting bolt 40 of the lock. This partition 8 is also provided with a central aperture in which is placed a sleeve 12, having an inwardly-projecting annular flange 13 at its lower end. Within this aperture and sleeve is loosely 4. The drawer 5 is likewise provided in front with a central vertical aperture 5, at the top ofwhich is secured a sleeve 5 and near the lower part of which is secured another sleeve 5, flanged at 5 and in all respects like the sleeve 12 and flange 13 of the partition 8 previously described. Within this aperture 5 is placed a rod 30, fitting loosely within the

sleeves

5 and 5 and provided with a shoulder 31, adapted to rest upon the flange 5 and a downwardly-projecting pin 32, adapted to pass through the sleeve and projecting downward toward the partition 8, which it almost reaches, but does not touch.

Supposing the parts to be assembled as shown in Fig. 2, it will be observed that the drawer 5 is unlocked, because the rod 30, with its dependent pin 31, is of such a length that The drawers 6 and '7 are provided with central vertical apertures, sleeves, and reciprocating rods similar to those described in connection with the drawer 5. Likewise the partitions 8 and 8 are provided with central vertical apertures and rods like the partition 8 just described. All of the rods in the drawers and partitions are arranged in alinement, as shown in Fig. 1.

Now if the key in the lock on the drawer 1 be turned so that the bolt 40 of the lock is projected upward it will lift the dependent pin 22 so as to raise the rod 20 off of its seat on the flange 13. As the rod 20 moves upward its upper surface will strike against the .lower part of the pin 32. This in turn will lift the rod 30 off of its seat,and its upward surface will strike against the pin in the partition S ,which in turn will move the longer rod in the drawer 6, and so on, lifting each rod upward, so that when it is attempted to remove the drawer forward the several rods engage with the sides applied to cases where two small drawers are 1 in g flan ge.

v the two rods of the drawer 6 beneath them,

as the larger drawer is locked by one such '20 and 20", placed within recesses 11 and 11 of the partitions and the drawers cannot be l moved from their places.

When it is desired to unlock the drawers, the key is turned in the lock, and the bolt 40 of the lock being thus depressed all of the different rods and pins fall into place by the force of gravity, the annular flanges 18 5 850., preventing the rods from falling far enough to drop out of the several apertures provided to receive them. In the form of my invention which I have illustrated and described all of the rods are in exact vertical alinement with the bolt of the lock on the lowermost drawer. This is not necessary,provided a laterally-extended bearing-surface is employed to transmit the motion from one lock and rod to the other. This modification enables the multiple lock to be placed above a wider one, so that both of the small drawers are locked by two or more upwardly-projecting rods in the same manner rod, and also enables two rods to be employed to lock the drawer-near its lateral edges. This modification is illustrated more particularly in Fig. 4. In this figure the same frame is shown as in Fig. land the same drawer 4, but the other parts are modified. Above the partition 8 are the drawers 5 and 6 and above the latter two

smaller drawers

7 and 7*, separated by a vertical partition 8. A recess 11, as before, is cut awayfrom the lower side of the partition 8 to receive the upwardly-projecting bolt 40 of the look. This bolt is lifted and depressed by means of the key 4:1, pivoted upon the projecting rod 42. A guardplate 43 is set'in the drawer flush with thetop edge of the front panel. There is a central aperture in the partition 8" in which is placed the sleeve 12, but it has no inwardly-project- Instead of that the bolt 20 terminates in a wide plate 25, which is provided on each side with two dependent guide-pins in the partition 8. When the bolt 40 of the lock is moved upward, it strikes the pin 22 and moves it upward and with it the rod 20 and the plate 25. Each of the drawers 5 and 6 is in this figure supplied with two reciprocating rods and pins, the same being in vertical alinement, so that the upward motion of the plate 25 transmitted to these rods will lock the drawers as before. The drawer 7 is, however, replaced by two smaller drawers 7 a and 7", each of which is provided with vertically-reciprocating rods in alinement with so that lifting both of these rods locks each of these two small drawers in the manner already described.

What I claim is,

1. The combination with a plurality of drawers or the like, each provided with a bolt normally held withinv one of its panels and all of the bolts in the series being in alinereae il ment, of fixed portions having recesses with which the bolts may engage in locked position, andmeans for moving all of the bolts simultaneously to lock the drawers.

2. The combination with a plurality of drawers or the like, each provided with a bolt normally held in its unlocked position within one of its panels and all simultaneously returned from locked to unlocked posi tion by gravity when the lock is reversed, all of the bolts in the series being in alinement, of means for moving all of the bolts simultaneously to lock the drawers.

3. The combination with a plurality of drawers or the like separated by partitions, each drawer and partition being provided with a bolt normally held within a panel and all of the bolts in the series being in alinement, of means for moving all of the bolts simultaneously to lock the drawers by moving the partition-bolts-into the drawer-panels and the drawer-bolts into the partition-panels and holding them in place after such movement;

4. The combination with a plurality of drawers or the like, of a series of bolts held within apertures in the corresponding panels of the drawers and prevented by suitable stops from falling out of position, of fixed portions having recesses with which the bolts engage in locked position, and means for simultaneously raising all of the bolts to lock the drawers.

5. The combination with a plurality of drawers or the like, of a series of bolts normally held in unlocked position within apertures in the corresponding panels of the draw ers and all of the bolts simultaneously returned from locked to unlocked position by gravity when the lock is reversed, stops to prevent the bolts from falling out of normal position, and means for simultaneously raising all of the bolts to lock the drawers.

6. The combination with a drawer or the like provided with an aperture in one of its panels and mounted in a fixed portion having a recess in line with the aperture in the panel of the drawer, of a bolt adapted to reciprocate in said aperture held normally therein in unlocked position and returned thereto by gravity when released from locked position, a stop to prevent the bolt from falling out of its normal position, and means operated by a key to lift the bolt in its seat to cause it to engage the recess in the fixed portion and lock the drawer.

7. The combination with a plurality of drawers each provided with vertically-reciprocatin g bolts held normally in position to admit of the opening of the drawers, of fixed portions having recesses with which the bolts engage in locked position, and means for raising the lowermost bolt of the series whereby each bolt lifts its neighbor to lock the drawer to which it is attached.

8. The combination with a plurality of IIO drawers and intermediate partitions, each provided with vertically-reciprocating bolts held normallyin position to admit of the opening of the drawers, of means for raising the lowermost bolt of the series whereby each bolt lifts its neighbor to lock the drawer to which it is attached.

9.: The combination with two drawers placed side by side each provided with an aperture in one of its panels and both mounted a in fixed portions provided with recesses in placed side by side each provided with. an ap-' erture in one of its panels and both mounted in fixed portions provided with recesses in line with the apertures in the drawer-panels; of a bolt normally held in unlocked position in each drawer-aperture, a single drawer be} neath the two drawers, two bolts in the lower drawer in line with the bolts of the upper drawers, connections between the bolts of the lower drawer, and means operating on said connections for simultaneously moving the bolts of the drawers into locked position.
