UNITED STATES FRANK SMITH BLUE, OF CARTHAGE, NORTH CAROLINA.

BULLETIN BOARD, BLAGKBOARD, AND'THE LIKE.

Application filed June 14,

This invention relates to bulletin boards and more particularly to a bulletin board of that type including a plurailty of pivoted leaves for the reception of announcements and the like.

An important object of this invention is the production of a device of this character wherein the leaves are so mounted that each and every leaf may be consecutively squarely faced to the observer and at the same time a structure provided which may be housed in an extremely flat compartment.

A further and more specific object of the invention is to provide in a device of this character a construction wherein the leaves are all rotatable about a central pivot but are connected with this pivot in such fashion that they may not only be bodily rotated thereabout but pairs of leaves may be rotated about pivots which connect them, thus in alignment with one another for observation.

A further object of the invention is to provide a construction of this character which is shaped suitable for use in the ofiices of plants, lobbies of hotels or other situations and will, in addition to performing its function as a bulletin board, may likewise serve as a general receptacle or storage device.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the urpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a front elevation of a bulletin board constructed in accordance with my invention, one of the doors being partially broken away and the other shown in the open position;

Figure 2 is a rear elevation of the bulletin board; 7

Figure 3 is a section on the line 3-3 of Figure 1;

Figure 4iis a section on the line H of Figure 3;

Figure 5 is a similar section with the leaves all disposed at one side of the cabinet.

Referring now more particularly to the drawings, the numeral 10 generally designates spaced standards which are connected 1928 Serial No. 285,470.

by vertically spaced horizontal wall elements 11 and 12. Beneath the lower wall element 12, a horizontally extending shelf 13 may be disposed, if so desired. The space between the wall elements 11 and 12 is preferably closed at the front of the cabinet by hinged doors l4 and the space between the wall element 12 and the horizontal shelf 13 is closed by a panel 15, which is preferably provided withan opening 16 for the reception of a drawer 17. i Y

The back of the cabinet has applied thereto a backing strip 18, which preferably extends to a point adjacent the floor, as more clearly shown in Figures 1 and 5. This backing strip may include hinged panels 19 which, when open, give access to the space between the lower wall element 12 and the shelf 13 at opposite sides of the drawer 17.

This backing may also have applied thereto hook strips 21 having clothing hooks 22 applied thereto and a mirror 23, if so desired.- Seated uponthe wall 12 at the center thereof is a bearing or spacer block 24: and this block and the partition have formed therethrough an opening 25 for the passage of a pivot bolt 26 which, above the pivoted block, is passed throughthe hinged eyes 27 of the leaves 28of a hinge. A vwasher or Washers 29 can be disposed between the bottom of the hinged leaves and the bearing block to provide a spacing adjustment and this adjustment can be secured by nuts 30 placed upon the lower end of the bolt. In vertical alignment with'the pivot bolt 26, a second hinged bolt 31 connects the leaves of a second hinge 32, washers 33 being preferably disposed between the inner end of the hinge and the partition 11. To corresponding leaves'of the hinges are secured bulletin panels 34, which preferably each comprise a suitable framing 35 surrounding a central board 36 which may be of any suitable char acter. To each of the bulletin panels 34 is hinged a similar bulletin panel 37, the hinge occurring at the same edge of the panels 34 which is connected to the leaves of the first mentioned hinges.

It will be obvious that the pins or bolts 26 and 31 form pivots about which either of the units represented by a leaf 34 and its attendant leaf 37 may be bodily rotated or about which the entire group of leaves may be rotated. Each leaf 375 may be moved about the hinges 38 which, connected to its main leaf 34 so that it aligns with its main leaf 34 and what are normally adjacent faces of these leaves are exposed to view. Referring to Figure 3, wherein a leaf 37 is disclosed as having been shifted into alignment with its leaf 34, it will be obvious that if the attendant leaf is swung about the pivot provided by the bolts 26 and these leaves will be then arranged in a position similar to the group of leaves 34 and 37 which are disposed at the same side of the central pivot and the adjacent faces of the leaves 34 will be arranged in alignment.

Moving the second leaf 34 to the opposite side of the central pivot will cause the leaf 37 associated therewith to be bodily shifted therewith until the second group of leaves occupies the position held in the illustration by the group first discussed. While the structure illustrated is that of a board for sup I orting bulletins, the panels may, of course, e employed as a black board, if appropriately painted or constructed of the proper material.

It will be obvious that with a construction of this character, there will be no diiliculty in separating the leaves or so positioning them that their supported bulletins may be readily viewed. it will also be obvious that the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention and I accordingly do not limit myself to such specific structure except as hereinafter claimed.

I I claim 1. In a bulletin board, opposed supports, aligned pivots carried by the supports, a plurality of pairs of leaves, one leaf of each pair being pivoted to said pivots, the leaves of each pair being hinged to one another upon hinges paralleling the pivots, each pair of leaves being independently movable about the pivot as a unit.

2..In a bulletin board, a cabinet, aligned pivots projecting into the cabinet from the upper and lower walls thereof .v a pair of leaves pivoted at corresponding edges to said pivots and swingable thereabout to lie at opposite sides of the pivots within the cabinet, and a second leaf associated with each of the first named leaves and hinged thereto along the edge which is engaged with the pivot.

3. In a bulletin board, opposed supports, a pair of leaves arranged therebetween, fixed pintles carried by the supports pivotally connecting the leaves to one another and permitting independent rotation of the leaves thereabout as a center, a second leaf associated with each of the first named leaves and pivoted thereto, the pivotal connections between the first and last named leaves permitting arrangement of the last named leaves at the opposite side of said pivots from the first named leaves.

4. In a bullet-in board, a pair of standards, horizontal. walls connecting the standards, fixed vertical pivots extending through said walls and aligned with one another, leaves pivoted at corresponding edges to said pivots, other leaves pivoted to said edges of the first named leaves, a backing connecting the standards and doors closing the space between the walls.

In testimony whereof I hereunto afiix my s nature.

FRANK SMITH BLUE.
