METALLlC FILING CASE OR CABINET.

SPECF'JICATION forming part of Letters Patent No. 435,877, dated September 2, 1890.

Application led March 5,1890. Serial No. 342,788. (No model.)

To all whom, t may con/cern:

Be it known that I, PHILIP H. YnwMAN, of Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Metallic Filing Cases or Cabinets,of

which the following is a specification.

rlhis invention relates to various improvements in the construction of metallic cases to receive books, papers, dec.

1o The objects of the invention are primarily to produce a strong, simple, and inexpensive case, the parts oi which may be readily constructed in duplicate by machinery.

In the accompanying drawings, Figure l represents a front elevation of a ease having my improvements embodied therein, a portion of the same being shown in vertical section on theline l l of Fig. Fig. is a vertical cross-section on the line 2 2 of Fig. l.

2o Fig. is a perspective view of one of the vertical end plates. Fig. i is a viewof a portion of one oi the horizontal shelves. Fig. 5 is a view ot" one oi' the vertical division-plates. Fig. G a view of one of the angular tieirons used in the corners of the ease. Fig. 7 is a perspective view of one oi? the vertical division-plates with the roller-supports applied thereto. Fig. S is a horizontal section on the line 8 Soi the preceding ligure.

3o The entire body of my case is constructed of sheet metal. It consists, essentially, of vertical end plates A A', a top plate l, a baseplate C, a back plate D, horizontal shelves or divisions E, extending from side to side, and

vertical division-plates F. The top, bottom, and end plates are each i'ormed of a single sheet of metal of suitable thickness to give reasonable rigidity and each curled or rolled at the forward edge to form a round bead a.

4o This bead gives to the case an ornamental appearance, prevents the metal from buckling or bending, and presents a round edge to prevent mutilation of the books o1l papers during their insertion or removal. The end plates are provided at the top and bot-tom with inwardly turned horizontal flanges, which are seated against the surfaces of the top and bott-om plates, respectively, and secured irn'ily thereto by rivets, screws, or

5o equivalent fastenings c?. The back plate,

which may be made of a single piece or in sections, according to the size of the case, is provided along its horizontal and vertical edges with a rearwardly-'turned-[lange d, shown in the several figures. The plate is inserted into the trame from the rear and its iiange secured to the sides, top, and bottom, respectively, by rivets d.

In order to strengthen the case and tie the parts firmly together, I employ at each corner 6o a strong angular rod, such as shown at G, Fig.

6, its two ends, which stand at right angles, being inserted one intothe bead attlle front of the vertical plate and the other into the bead at the front of the horizontal plate, as clearly shown in dotted lines in Fig. l.

The parts already described constitute the frame-work or body ot the case. lithin this body I mount any required number of horizon tal shelves or division-plates E, extending 7o from side to side and from frontI to back. Each ot' these shelves E is commonly cone structed in a single piece, its forward edge curled to form the rounded bead and its ends bent downward in the forni of flanges These flanges are seated over and behind upright lips a3, formed on the side plates by punching the metal inward from the outside, these lips serving not-only to sustain the shelf, but also to tie the sides of the body inward 8o against the shelves to prevent the body from spreading. The shelll is held down in engagement with the lips a3 by overlying lips c4, which are also formed by punching through the metal from the outside. The shelves are S5 inserted by sliding them horizontally to their places from the iront or rear ot the case, and they may be held in place simply by the frietion or by providing them at the rear edge with a downwardly-turned flange c, to be riveted or otherwise attached to the back plate. The vertical division-plates F, by which the spaces between the shelves are divided into compartments or pigeon-holes, consist each of a single sheet of metal, such as 95 shown in Fig. 5, its front vert-ical edge being curled to form a bead f', its upper and lower edges turned over to form horizontal lianges j"2 and its rear edge turned laterally to form a rlange f3. These plates are seated IOO between and against the horizontal shelves and between the shelves and the top and bottoni plates of the case, and are secured in place by means of lips c and e2, punched through the shelves, these lips being in form and arrangement identical with the lips d'3 and a4 on the end plates. Each of the shelves 1s provided, as shown in Figs. l and 4E, with two sets of lips, one punched upward and the other downward, in order to hold the divisionplates above and below them.

Then the ease is to receive books, I provide it Wi th what are known as roller-shelves that is to say, with a series of horizontal rolls Il, arranged in sets, several in the same horizontal plane. These rolls are sustained at their ends, as shown in Figs. 7 and S, by studs or pivots 7L, projecting' from bars h', secured to the vertical plates of the case. These bars may form the ends of the roller shelves or frames.

Each of the vertical plates is provided, as shown in Fig'. 7, with two vertical rows of holes h2. Two plates or bars are applied in line with each other to opposite sides of the su1 portixigpiate and secu red thereto by bolts h3, passing through the holes. By changing the bolts from hole to hole the height of the bars 7L may be changed, and thus the distance between the series of holes modified to suit the size of thickness of the books to be introduced.

In order to prevent books from being chafed in their sidesl or edges, more especially large books inserted in horizontal positions, I propose to provide at the front of each of the division-plates a vertical roller I, sustained at its ends in ears or plates t', riveted to the vertical plate. I prefer to use a series of short rolls arranged one above another, as shown; but long` rolls extending from top to bottom of the case may be employed.

I-Iaving thus described my invention, what I claim visl. In a metallic case, the frame consisting of the vertical side plates and the top and bottom plates connected thereto by inwardlyturned Hanges and rivets, in combination with the back plate inserted within said frame and having its edges flanged in a rearward direction and secured by rivets, substantially as shown.

2. In a metallic case, the vertical side plates having lips punched inward therefrom, in combination with the division plates or shelves having their ends flanged and engaged with said lips, substantially as shown.

3. In a metal case, a vertical plate and a horizontal plate joined thereto, each curled into tubular form at one edge, in combination with an angular tie-iron having its ends inserted into the tubular portions of the respective plates.

4. A plate for a metal case, provided with two series of lips, as a3 and a4, punched therefrom, the one series standing perpendicular to and the'other series substantially parallel with the surface of the plate, whereby they are adapted to engage and hold a second and flanged plate.

5. In a metal case, the shelf or division plate E, having the iianges at its ends, in combination with the vertical sustaining-plates, each having' integral therewith horizontal and also vertical lips, substantially as shown, whereby the shelf is sustained and its disengagementfrom the sustaining-lips prevented.

6. In a metal case, the combination of two parts at right angles to each other, one having a fiange across its end and the other having lips parallel with its face to engage behind the flange and also lips perpendicular to its face to prevent the disengagement of t-he ange, as described and shown.

7. In a metal case, the horizontal shelves and vertical division-plates, in combination with the vertical rolls and their sustainingears attached to the vertical plates.

8. In a metallic case, the vertical plates provided with a series of holes at different heights, in combination with the horizontal rolls, their sustaining-bars, and the bar-sustaining bolts insert-ed through the vertical plates.

9. In a metallic case, the combination of a vertical plate, two roll-sustaining bars applied to opposite sides of said plate, a series of holes at different heights, and bolts each passing through thc vertical plate and the two bars, substantially as shown.

In testimony whereof I hereunto set my hand, this 7th day of February, 1.890, in the presence of two attesting witnesses.

PHILIP Il. YAWMAN. Vitnesses:

FRED F. CHURCH, A. A. DAVIS.
