'Application filed November 15, 1916.- SeralfNo. 131,389.

To all whom it may concern:

Be it known `that I, EUGENE W. HAwLnY, a citizen of the United States, residing at Philadelphia, `county of Philadelphia and VState of Pennsylvania, have invented a new and useful improvement in `Irunk-Locllzs, of which the following is a full, clear, and eX- act description, reference being -had to the accompanying drawings, which form a part of this specification. t

The object of my invention is to secure together the two members of a trunk by means of pairs of complementary locking members at several points along `the length of the trunk and operable from a single member, such as a hasp. r More specifically, `the ob jects of the invention are: to insure accurate and certain engagement between the locking members of'each pair, to provide a double stop to with more certainty insure that the movablelocking members will voperate only within prescribed limits, and to simplify the connection between thehasp 'and the movable locking members.

A preferred embodiment of my invention is shown 1n the accompanying drawings in l whichon the inside thereof carries Figure lis a front view of a wardrobe trunk containing my inventionf Fig. 2 is a sectional elevation .through the two sections of the trunk, the locking mechanism being shown in elevation. Fig. 3 is a detail vview of a `pair of locking members and the actuating mechanism for operating the movable `member with the `parts in unlocked positionbut ready for engagement. Fig.` l is a detail view of the2 actuating mechanism shown in Fig. 3 but moved into position to effect engagement betweenthe locking members. Fig. 5 is a horizontal cross section throughjthe two locking members. Fig. 6 is a section on the line 6-6 of Fig. 3.

The trunk comprises two sections a and b hinged together in the usual way. The trunk is shown in an upright position, as it is `intended to illustrate that 4type of trunk known as a wardrobe trunk. Onthe outside of one trunk section ais pivotcd, on a horizontal axis, a hasp support c, to which is pivoted, on a vertical axis, the hasp d, which is adapted to swing into engagement with a socket c on the other trunk section Z).

The turnable pivot of the hasp support c extends through the wall ofthe trunk and the disk f (which is in effect a crank arm) and `a stop g.

Slidable vertically in guides y' on the inner wall of trunk section a is a bar z'. Connectingithe bar z' and a pin on the disk f is a rod h.

The bar 'i has securedto it a plurality of locking members having upwardly-extending ,wedge-shaped projections 7c. wall of the section b has secured to it a plurality of locking members la having sockets adapted to receive the projections 7.1.` The sockets of vmembers on are provided preferably with wedge-shaped end walls corresponding in contour to the contour of projections 7c, although this feature is not essential, as if one locking member is wedgeshaped, the function sought will be accomplished. The sockets of `members m are also provided with projections c'neatly fit, thereby insuring the perfect alinement of the two trunk sections when they are interlocked. To insure the entry of the projections into the sockets, the side walls of the projections 7c are tapered upwardly as shown in Fig. 6.

The mode of operation of the device is as follows:

Assume that theltrnnk is open and that the hasp Z is swung into an approximately vertical position, as shown in Fig. 3. To close and lock the trunk, the trunk sections are first swungtoward each other so as to bring their opposing vertical edges into approximately close engagement. The hasp lis then swung, on its horizontal pivot, from the position shown in Fig. 3 to the position shown in Fig. il. This moven'ient, `through the medium of disk f and connecting rod fh, draws up the bar a', causing the projections 7a to enter the sockets of members m. If the two trunk sections are not in enact alinement, the tapered end of each projection 7c will nevertheless enter its corresponding socket and draw the trunk sections into exact alinementas the bar i moves up. At the same time, owing to the wedge-like engagement between the two locking members, the two trunk sections will be drawn more tightly together. The hasp Z is then swung on its vertical axis into engagement with the socket e.

It will be observed that the movement of the bar i is exactly parallel to the direction of its extension. When the bar i is moved locking The inner side walls, into which the 1 locating two up into the locking position shown in Figs. 2 and 4, its movement, when thek hasp 0l reaches the horizontal position necessary for its subsequent engagement with the socket c, is arrested by a double stop. In the first place, one of the flat faces of the stop g contacts with the straight edge of the lconnecting rod 7L. In' the next place, one of the movable locking members k contacts with one of the guides j for the bar z'. Conversely, when the bar c' is moved down away from the locking position into the unlocking position shown in Fig. 3, its'movement is arrested, iirst by contact of stop n on the rod z, with the bar i and again by the contact of another` locking member 7c with another guide y'. This double stop is important in that in the eventv of Wear and tear of either` part, and particularly lost motion arising therefrom in the hasp connections, the other lock will be effective. The direct lock for the bar is conveniently arranged without the provision of any extra parts by of the guides j between two of the movable locking members la.

It will also be observed that in its locking movement the bar z' moves up and not down. This is advantageous as the locking operation involves a pull away from Hoor and not a push against the floor, thereby enabling the locking operation to be effected with substantially less muscular force.

Having now fully described my invention, what I .desire to claimand protect by Letters Patent is:

l. In a trunk, the combination with the two hinged sections thereof, of a main locking device pivoted to one section, a bar slidable on the same vtrunk section longitudinally of the trunk, connections between the main locking device and the bar to convert a turning movement ofthe formerV into a longitudinal movement of the latter, .fixed locking members on the other trunk section each comprising a relatively long and narrow socket and complementary locking members secured to the bar each comprising a flat and relatively thin projection adapted to engage the corresponding socket, the locking members of each complementary pair having an inclined edge adapted to engage one end of the corresponding socket to draw the two sections toward each other, the side walls of each projection being beveled adjacent its end andthe side walls of the socket flaring, outward adjacent its mouth to draw the two sections into exact alinement.

2. In a trunk, the combination with the two hinged sections thereof, of a main locking device pivoted to one section, a bar slid able on the same trunk section longitudinally of the trunk, connections between the main locking device and the bar to convert a turning movement of the former into a longitudinal movement of the latter, two fixed locking members on the other trunk section, two complementary locking members on the bar, and guides for the bar on the first trunk section, two adjacent guides being spaced apart a shorter distance'than, and located between, two adjacent movable locking members and thus acting as stops one to arrest the movement of the bar in one direction and the other to arrest the movev-ment of the bar in the other direction.

In a trunk, the combination with the two hinged sections thereof, of a main locking device pivoted to one section, a crank arm and a stop secured to and turning with the main locking device, a bar slidablc on the same trunk section longitudinally of the trunk, a connecting rod pivoted both to the bar and to the crank arm, fixed locking members on the second trunk section, complementary locking members secured to the bar, guides for the bar on the first trunk section, and a stop on the connecting rod, the rst stop adapted to contact with the connecting rod and thereby limit the movement of the bar in one direction and the second stop adapted to contact with the bar and limit its movement in the opposite direction'.

4L. In a trunk, the combination with the two hinged sections thereof, of a main locking evice pivoted to one section, a bar slidable on the same trunk section longitudinally of the trunk, connections between the main locking device and the bar to convert a turning movement of the former into a longitudinal movement of the latter, fixed locking members on the other trunk section. complementary locking members on the bar, stops movable with the main locking device and adapted to arrest the movement of the main locking device and bar in opposite directions, and guides for the bar on the rst trunk section adapted to contact with the movable locking members, and arrest their movement and consequently the movement of the main locking device and bar in opposite directions.

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this seventh day of November, 1916.
