FASTENING nnvicn non. nmenn BOX MEMBERS.

Specification of Letters Patent. Patented J 11119 29, 1920.

Application filed October 1, 1919. Serial No. 327,701.

To all whom it ma concern:

Be it known that I, CHARLES C. ARM STRONG, a citizen of the United States, and resident of Huntington, West Virginia, have invented certain new and useful Improvements in Fastening Devices for Hinged Box Members, of which the following is a specification.

My present invention relates to combined fastening devices and locks designed more especially for boxes of the type comprising two tray like members hinged together with an intermediate hinged flap such as dis closed in Letters Patent of the United States granted to me July 4, 1916, under No. 1189902.

The invention aims to provide a combined lock and latch which may be readily struck up from sheet metal and which shall be com posed of a minimum number of parts there by greatly reducing the cost of manufacture.

I have also aimed to provide'a combined lock and latch in which one of the members of the fastening device shall serve as securing means for the handle.

With these and other objects in view the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and defined by the appended claims.

An embodiment of my invention is illustrated in the accompanying drawing in which:

Figure 1 is a plan view of the box.

Fig. 2 is a front elevation.

Fig. 3 is a partial central transverse section.

Fig. 4 is a partial tion through the closed box showing the fastening device as it would appear from the inside of the box.

Fi 5 is a detail plan view and Figs. 6 and T are plan views of the two sheet metal members which comprise the fasteningdevice.

In these drawings 1 and 2 comprise the two main members of the box which is shown as representative of any device to which my improved lock or fastening may be applied, each of which is shown in the form of an elongated shallow tray, these two members being hinged together at 3. The member 1.is provided with a turned edge 4 and the member 2 is provided with a flared edge 5 adapted to fit over the turned edge 4, when one memberis swung over upon the central longitudinal secother member as shown in Fig. 3. A leaf or flap 8 is provided hinged about thesame axis as the hinged members at 3. The flap or leaf 8 is adapted to cover either member 1 or 2, of the box.

My improved locking device is shown as applied to the box at the point 12 (Fig. 2) and this, in addition to locking the two main members together, will lock the flap or leaf 8 in position by engaging the edge of the,

opening at, 8 formed in said leaf. The wall of this opening is adapted to engage the end 15 of the catch 15 forming a part of the lock, this catch having. its edge inclined for the edge of the opening to ride against.

A finger opening is provided at 8 by which.

the user may lift the leaf from the catch, it being necessary for him however to exert slight pressure laterally or in the direction of the arrow on in Fig. 8' to spring the catch out of connection with the'edge 8 of the leafv The catchgwhich serves to hold the two box sections together and to retain the partition is formed as an integralpart of a single blank, shown in Fig. 6, which also serves as the catch spring, cooperates with. the lock and is utilized as means for retaining the handle which is indicated at 18. i T

To this end this blank is stamped fromsuitable spring metal, and comprises a cross bar 15 with portions 15 and 15 extending transversely from opposite sides thereof.

The extremity 15 of the portion 15 is folded over' upon itself to form the catch hereinbefore referred to as shown in Fig. 3 and it is provided with anoopening. d designed to engage a projection 1* carried by the box section 1. The two end portions of the bar 15 are designed tobe secured to the inner face of the front Wall of box section 2 by suitable means, such as rivets 6 andthe portion 15 has its end folded back upon itself to form a holder, for the 1 movablemember of thelock. y This comprises a single sheet metal stamp ing having its main portion of substantially saucer shape as indicated at 16 surmounted by a struck up circular'boss 16*? which is designed to engage a circular opening 6 in the overturned portion 15after said movable member has been inserted therebeneath, said circular boss forming a pivot on which said movable member oscillates. I

The central portion of this boss is struck may be oscillated in the manner hereinafter described to lock and unlock the box.

The front wallof the box section 2 is provided with an opening in which is inserted a push button 17 which is preferably formed by stamping up a piece of sheet metal into cup shape having its closed outer face provided with a key slot 17 and having on its inner edge a marginal flange 17 designed to overlie the inner face of. the'box. section 2 beneath the member 15 by which it is held in position. The member 15 being of spring metal holds the push button normally pressed outwardly in the positionshown in Fig 8, but pressure on the push button forces the central portion of the member 15 inwardly toward the interior of the box,

removing the-edge of opening (5 from en-' gagement with projection l thus releasing the catch or latch which holds the box sections together.

One of the rivet: holes, either in the member 15' or in the box section 2 iselongated to permit the flexing of the member or bar 15.

The member 15 is also provided with an alining key opening 7 and a suitable key may be inserted therethroughand on turning the key its web or bit will engage the projection 16 and rotate the member 16.-

This member is providedwith alocking projection 16 which is designed to engage an undercut recess or slot 1 in the projection 1 thereby holding the portion 15 against inward movement and preventing the disengagement of the catch.

The member 16 is provided with ears or projections 1Q? which-engage the edges of the base of portion 15 and serve as stops for limiting the movement of member 16 and the member 15 is provided with struck up bosses 15 which bear against the faces of projections 16 and offer frictional resistance to its movement, thus holdingit in its locking or unlocking position.

I also utilize the member 15 as a means for securing the handle 18 to the box and to-this end provide the ends of thebar with projecting portions 15 which are bent to semi-circular or hooked form and inserted through slots inthe front wall of the box. The straight alined end projections of the handle are then placed in these hook shaped recesses where'after the bar 15 is'placed or swung flat against the inner wall of the box section, holding the handle securely in position. The projection 1 may be made in the form ofa solid metal stud having a reduced portion passed through an opening in the wallof'box section 1 and u set to hold it in place as clearly shownin ig; 3;

In the operation of my improved fastening means, when the locking projection is out of engagement with the slot l and it is desired to open the box, an inward push upon the push button 17 will cause the tongue part 15 to move inward until the opening at ceases to engage the'projection 1*, when the sections of the box may be swung apart. As the upper section Fig. 1 is opened or swung upwardly,the partition 8 will be carried with it by engagement of the portion 15 with the leaf or partition. After the said upper section has been swung back to a horizontal position andit isdesired to have accessto the interior thereof the leaf or partition may be swung away from section 1 by pressing catch portion 15 toward the front of the box (or to the left from the position shown in Fig.1) which will bring its free or holding ends into alinement with the cut away portion of. the leaf or partition which may then be swung away from section 1 by inserting the finger in the opening 8.

When this box is closed and it is desiredto lock it against being openediexcept by the use of a key, such key is inserted in the alining key openings or slots 17 and 7 until its web or hit is in line with the projectionlG" of the member 16. The turning of the key will thenrotate the member 16 until its projection 16 engages the under cut portion or slot 1 in the projection 1 which under cut portion lies to the rear of the portion 15 of the spring tongue. In this position, the part 15 is locked against inward movement, or in other words, cannot be pushed in by pressure on the push piece or button and consequently the sections are locked together.

Having thus described my invention what I claim is:
