IMPROVEMENT H'Ll POST-OFFICE BOXES.

Specication forming part of Letters Patent No. 194,890, dated September 4, 1877; application filed August 3, 1877.

To all 'whom it may concern Be it known that we, BUSHROD H. CAMP, of Charlestown, in the county of Middlesex and State of Massachusetts, and WALLACE HUCAMP, of Waterbury, in the county oi' New Haven and State of Connecticut, have invented certain new and useful Improvements in Post- Office Lock-Box; and we do hereby declare that the following is a full, clear, and exact description thereof, whichwiil enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in post-office lock-boxes.

The invention consists in a postofce box as a new article of manufacture complete in itself, admitting of any number of boxes beingcombined and secured together; also, in the special construction and arrangement of parts, which will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appertains to make, construct, and use the same, we will now proceed to describe its construction and operation, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure lis a perspective view, showing four boxes placed in a casing, shown part in section. Fig. 2 is a central vertical longitudi nal section of one of the. boxes. Fig. 3 is a front view oi' the box-door, showing the face of its frame removed. Fig. a s .ows the door provided with one side loi" a hinge. Fig. l5 shows the .door having a tongue formed into one side or member of a hinge. Fig. 6 is a view showing the back part `of the box provided with a device for4 holding: the name of' the person using the box. Fig. 7 is a view showing the name-holding device detached, alsoits means of attachment. Fig. Sis a central vertical section through the door-glass and its supporting device.

A represents the box provided on both sides with vertical grooves a and on the top and bottom with transverse grooves b. The front of the box is cut away at m to receive the flanges e of the frame B, in order that the smoothness or uniformity of the sides may not be obstructed.

To the frame B is hinged the door C, which is cast or stamped from sheet metal, as may be desired. When the door is cast it is provided With hinges d, and when stamped from sheet metalit is formed with extensions e,which are bent to form a hinge.

The door is hung by passing the hinge into recesses cut in the frame, and through the eye ofthe hinge is passed a wire, j', which extends all around the frame in the trough between the iianges c. vents the face g of the frame from beingmashed in.

The frame is also provided with a recess, 72 into which the door tits, so as to be somewhat back of theface, thereby rendering it diffx'd cult to be opened by passing a sharp instru ment of any kind into the crack around the door.

The door is provided with glass at the top and bottom to admit light and enable persons to see the contents of the box. The glass i5 held by cylinders 'i slit on one side, soldered to the door. One corner of each cylinderg's turned up and the glass forced in. Said cyi inders are made of suitable metal, so that they will act as a spring, thereby securely retaining the glass in place and preventing any rattling on shaking the door.

At the back of the box is placed a device for holding the name of the person using the box. This device also prevents any papers or letters that may be in the box from falling out.

When any number of these boxes are placed in position-i. e., side by side and one above the other--the grooves a and b are in a line down and acrossthe boxes. Into these grooves are placed ns D E, which, with the grooves, form feather-joints, thereby locking them together and preventing any displacement of any one of the boxes.

Any desired number of the boxes may be placed in a casing, F, having grooves a', b', and c, and any number of cases locked together with tins. These cases also serve as a receptacle, into which the boxes may be packed This wire strengthens and pre*` i ber combined and secured together in :my deslred forni.

Having thus fully described our invention,

what We claim as new, and desire to secure by Letters Patent, is-

1. .As a new article o'i' manufacture, it postofce letter-box, A, beingA made independent and complete in or of itself, and provided with Ineens, substantially as described, which admit of any number of boxes being combined and. secured together.

2. The box A, provided near the back With grooves a on two vertical sides, and near the front, on the top and bottom, with grooves b to ii'eceive iins D and E, by which ineens they are locked together to prevent one or more oi' the boxes from bein g withdrawn, substan tielly as described.

3. The casing F, having' grooves' a', b', and

c, in combination with the boxes A, provided with grooves a, b and fins D and E, substantially as described.

4. A postofee letter-box door, provided with slit cylinders f, substantially as shown and described, each adapted to receive one odge of the glass, and, by its constant pressnre, secure the glass in place and prevent its rattling', as se?. forth.

ln testimonyr that We claim the foregoing als our own We affix our signatures in presence ot' two witnesses.
