ljhlll STATES MAX STOCKOV, OF NEW YORK, N. Y.

WARDROBE TRUNK.

Application filed April 4, 1825. Serial No. 20,602.

This invention relates to wardrobe trunks arranged with a tier of drawers, and relates particularly to means to lock and unlock the drawers when closed by the closing or opening movement of one of the drawers,

and it is the object of the invention to provide drawer locking means of this character that is simple in construction and operation and effective in keeping the drawers closed to withstand the hard usage to which a wardrobe trunk is subjected.

In carryingout the invention I provide a bar arranged with alined perforations and fix a carrier of channel shape in cross section to the trunk wall in the rear of a tier of drawers in which the bar is mounted to have longitudinal adjustment, said bar normally assuming a position and supported with the perforations therein in register with perforations in the carrier. Each of the drawers has a pin projecting from the back arranged to engage the perforations of the bar and its carrier when the drawers are closed. All of the drawer pins, with the exception of a pin carried by one drawer, have a transverse recess cut through the lower wall portion. The unrecessed pin is arranged out of line with the bar and carrier perforations, and the bar perforation in which said pin is adapted to engage has a cam member arranged adjacent thereof with which said pin engages as the drawer is closed and operates to move the bar longitudinally thereby interlocking the wall of the bar perforation with the pin recesses and holding the drawers against outward movement and the drawers arevlocked in closed position by a key operated lock having a spring influenced bolt mounted on the drawer arranged with the bar adjusting pin.

In the drawing accompanying and forming a part of this specification, Figure 1 is a front elevational view of a wardrobe trunk opened showing the locking means in dotted lines.

Figure 2 is a cross sectional view of the trunk, taken on the line 2-2of Figure 1, looking in the direction of the arrows, showing the drawers in unlocked engagement with the locking means.

Figure 3` is an elevational View of the locking bar looking at the front.

Figure 4; is a longitudinal front View ofa 55 carrier and mounting member for the locking bar. i

Figure 9 is a side view of the bar adjusting pin carried by the top drawer.

Similar characters of reference designate like parts throughout the different views of the drawing.

An embodiment of the invention is illustrated in the drawingin connection with a wardrobe trunkV 10 arranged with a tier of 'drawers 11 having sliding movement in said trunk on slidesl 12 mounted on the side walls of the trunk. The locking means for lockingrthe drawers comprises a vertical locking bar 13 having alined' perforations 14 of U-shape with the exception of the top perforation which is round. A channel bar 17 in which the locking bar 13 is slidably carried is fixed on the trunk wall in the rear of the drawer by means of screws engaged in perforations in flanged edge portions 18, lugs 19 stamped from the carrier holding the locking bar in engagement with the channel bar and in spaced relation to the trunk wall, flanged portions 20 at both ends of the channel bar bent at right angles to the bar acting as a support and stops for limiting the movement of the locking bar. The connecting portion of the channel bar 17 has perforations therein with which the perforations in the lockingbar 13 register in the normal position of said bar supported by the lower flange 2O of the channel bar. One of said perforations, in the present instance the one at the top of the bar, is elongated, as shown atl 22 (Figure 4). The upper circular perforation la in the locking bar has a tubular member 15 fixed therein which projects forwardly of said bar and slidably engages in the elongated per-4 foration 22 of the channel bar, said pro-l jecting member engaging with the lower wall of said perforation 22 in the normal position of the locking bar, as clearly shown in Figure 5. The wall of said member 15 at the end projecting through the elongated slot 22 is beveled, the bevel inelining from the outer wall in a direction toward the axis of .said member and serving as a cam edge as hereinafter described.

Pins 23 are lfixed in plates 211 to extend laterally thereof, (Figures S and 9) and whereby the pins are mounted upon the rear wall of the drawers 11 in alinen'ient with the registering perforations in the locking end channel bars 13 and 17 with the exception of the pin mounted upon the upper drawer which is offset upwardly with relation to the opening in the cam member 15 fixed in the upper perforation of the locking bar 13. Each of the pins Q3, with the exception of the pin mounted on the upper drawer, has a transverse recess 23 and the pins are mounted on the drawers so that this recess is at the bottom. rl`he ends of the pins are beveled or rounded as shown.

To unlock the drawers the upper drawer is withdrawn as shown in Figure 2 when the locking bar will move by gravity to position to be supported by the lower flange 2O of the channel bar 17 with the perforations therein in register with the channel bar perforations. 1n this position of t-he locking bar the drawers may be moved outward to open position or closed. With the drawers in closed position as the drawer carrying the offset pin is closed, the beveled or rounded portion of the pin 23 engages t-he bevel 1G of the tubular projecting member 15 as shown at 26 in Figure 5, and thereby moves the locking bar upward so that the member 15 abuts against the upper wall portion of the elongated perforation 22 and brings the horizontal wall of the perforatio-ns 111 into engagement with the transverse recesses in the pins 23, as shown at 27 in Figure 6, thereby locking the lower drawers in closed position. When the drawer carrying the offset pin is opened, the said pin is moved out of engagement with the projection 15 and the locking bar resumes its pin releasing position by force of gravity.

To retain the upper drawer closed and thereby the locking bar in. its raised position with the perforations 14 in interlocking engagement with the pin recess 28 to lock the lower drawers in closed position, the upper drawer is provided with a latch or lock 2S, perferably key operated, and having a spring influenced bolt adapted to co-operate with a keeper fixed to the trunl wal l.
