INTERNAL STAY FOR TRUNKS, BOXES, 80c.

SPECIFICATION forming part of Letters Patent No. 505,939, dated October 3, 1893.

Application filed July 31, 1891. Serial No. 401,330. (No model.)

To all whom it may concern:

Be it knownthat I, JOHN THoMAs DWYER, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented a certain new and useful Improved Internal Stay for Trunks, Boxes, or other Receptacles; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has forits object to produce a device applicable to the interiors of trunks, boxes or other receptacles, with a view to preventing the ends, front, back, top, bottom, edges, corners and their various junctions from being smashed, forced outward or mate rially damaged.

It consists of an arrangement of bearing plates in various forms secured to the weakest parts of the trunk or box or the parts thereof called upon to bear the greatest strain, and stays removably connected together and with such plates. For full comprehension however of the invention, reference must be had to the annexed drawings, in which like symbols indicate corresponding parts and wherein-- Figure 1 is a perspective view of an open trunk with trays removed to disclose my improved stay; Fig. 2 a plan view of the body of such trunk; Fig. 3 a vertical transverse section of same on line o: 00 Fig. 2; Fig. 4 a detail of the stay in the lid; Fig. 5 a view showing the application of angle strips for strengthening the corners of the trunk and Fig. 6 a view of one of said strips detached.

A is the body of the trunk or box, on the interior of the back, front, ends and bottom of which are screwed or otherwise attached, bearing plates B. These bearing plates B are fiat and preferably circularin form with their peripheries scalloped or provided with radial projections B or having sockets formed in nected with them, as will now be described,

and at the same time reinforce the edges, corners, and the several junctions of the receptacle.

The stays proper G, C, O and O are constructed preferably of hard wood, thin metal, or any other suitable material, oblong in cross section and when formed of wood are preferably provided with metal knuckle plates D at their ends adapted to be connected in hinge form with knuckles D, projecting from the centers of the bearing plates B, by pins E. The stay C extends in one piece, thin edge upward, between the bearing plates carried by the back and front sides of the trunk; those 0 0 being arranged flatwise, or broad side upward between the bearing plates at the ends of the trunk and a connecting plate F carried in a central position on' the bottom edge of the stay 0 and to which they are hinged, the stay 0 which is located between such connecting plate F and the bearing plate on the bottom of the trunk being detachab'ly hinged to such plate by knuckles and a removable pin E as before'described. This last stay C is rendered extensible as to length by making it in two parts slotting one of such parts and passing a set screw 0 through such slot to the other part, thus allowing it to be contracted in length and turned upon its hinge connection with the plate F to the position shown by dotted lines in Fig. 3.

The parts above described are specially adapted to strengthen the bottom, ends and back and front of the trunk and I will now describe the staying arrangement for the corners formed by the junction of the back, front and ends of the box.

A plate G having four knuckles G G G G each at an angle to the center thereof which is perforated to fit over the plate F is secured to the stay 0 preferably by riveting and has hinged to such knuckles in the same manner as the stay 0 is to the plate F four other stays G G2 G G extending flatwise from such plate to the corners of the trunk as shown where their ends, which are provided with foot plates G carrying a sliding bolt g and projecting lugs g g are connected to corner plates G suitably secured in place and having sockets hh h to receive respectively the bolt g and lugs g g.

The object of hinging the stays as shown and described is that by releasing the one C from the bearing plate on the bottom of the receptacle it can be turned up and held to stay 0 and by disconnecting the stays C C -F F from their bearing plates at the ends and corners respectively of the receptacle they can be turned up and held together, or the whole arrangement, after releasing the pin connecting the stay (3 to the front hearing plate, can be swung to the back of the receptacle or to one side leaving the contents of the bottom free, and, furthermore, by releasing stay 0 from the bearing plate at the back of the receptacle the entire stay arran gement can be removed altogether from position if desired.

An arrangement almost precisely similar to that used for the bottom of the receptacle is applied to the under side of the top of the lid, J being the bearing plate, J the vertical stay in this case usually in one piece and J a fourarmed stay arranged fiatwise and corresponding in position to the stays O and O (1'. The lower face of this stay J is flush with the edge of the lid and its ends made preferably in dovetail form so as to resist strain inward or outward. A similar stay to J and lettered J is also run upon the upper edge of the receptacle directly under the stay J for the same purpose.

To strengthen the corners formed by the junctions between the bottom, back, front and ends of the receptacle body and the like junctions in the top, I take strips, K, of metal somewhat greater in length than the width, transverse reach, or depth of the parts of the trunk enumerated, slit centrally at both ends and in equal proportions of their excessive length over the corners they are to fill, those which are to be placed in the horizontal corners; bend them longitudinally on the line of such slits to a transverse right angle and then bend the divided ends in to overlap and form, so to speak, an angle iron with two sides and square ends. The strips filling the vertical corners, will of course, only be slit at and have one end bent in square, and on reference to Fig. 5 it will readily be seen that when the several strips are set in position with their square ends nested together the corners of the receptacle will be well-nigh indestructible. The several stays could of course be made of metal rods and adjustable as to length by constructing them in two parts, screw threading the meeting ends, and

using right-and-left-hand screwed couplin The bearing plates, angle strips and corner plates will be secured in place in any suitable Way by screws, rivets, &c.

hat I claim is as follows:

1. A stay for trunks, boxes and other re ceptacles, composed of bearing plates-secured internally to the center of the bottom, sides and ends of the trunk, box or receptacle,-and a removable stay or stays connected with such plates, for the purposes set forth.

2. The combination with the bottom, sides, ends and corners of a trunk;-of bearing plates secured to such parts, and a removable stay or stays connected with such plates for the purposes set forth.

3. -In combination with the back and front of a trunk or box,bearing plates secured to such parts, stay 0, and means for locking the ends of same to said plates so as to hold such plates and the parts carrying them against bulging movement inward or outward.

4.. The combination with the back and front, the ends and bottom of a trunk or box,of bearin g plates secu red to such parts, and stays with means for pivotally and removably connecting such stays with each other and with said plates, substantially as set forth.

5. The combination with the lid of a trunk,of a bearing plate on the inside of same, a horizontal stay secured at its ends to the edges of such lid and a vertical stay between the bearing plate and said horizontal stay, all as herein set forth.

6. In combination with the body of a trunk, vertical plates in the corners: a central plate secured to stay 0 and radial arms hinged thereto and bearing against corner plates, all as herein set forth.

7. The combination with the body of a trunk, and removable stays, of the corner plates G with means for locking such stays and plates together, and corner strips K K as and for the purposes set forth.

8. The combination with the dovetail notched edges of the trunk and its lid, of the stays J 2 J 3 having their ends dovetailed to fit such notches, for stiffening the edges of the trunk as shown.
