SWINGING DISPLAY-LEAVES.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed April 25, 1908. Serial No. 429,140.

To all whom it may concern:

Be it known that I, ALFRED M. PARKS, of Philadelphia, in the county of Ihiladelphia and State of Pennsylvania, have invented certain new and useful Improvements in Swinging Display-Leaves, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to a substantial and durable display device for carrying swinging leaves, such as may be used for displaying railroad time-tables, telephone indexes, notices or other similar objects in public places.

One object of my invention is to so construct the leaves as to thoroughly protect the displayed object from injury or wrongful removal.

Another object of my invention is to facilitate the ready removal of any one leaf by a person authorized to do so, without disturbance of the others.

Another object is to so construct and mount the leaves as to permit the removal of the cards or other displayed objects from the leaves, as soon as the leaf is detached from the stand, but to make such removal impossible while the leaf is in lace.

Other useful features of t e invention will be referred to in the specification.

In the accompanying drawings, Figure I, is a plan view, and Fig. II, is a front elevation of a display stand embodying my invention. Fig. III, is a central vertical section along the line III, III, of Fig. I. Fig. IV, is a central horizontal section on an enlarged scale of a single display leaf taken along the line IV, IV, of Fig. III. Fig. V, is a detail as hereinafter explained.

As thus illustrated, the device includes a permanent back-board 1, provided with a lower ledge 2, and an upper ledge 3. These parts may conveniently be made of wood, and may be properly ornamented. The lower ledge 2, is provided with a series of pivot or socket holes 4, which act as thrust bearings to receive the lower ends of the pivotal supports for the leaves. The upper ledge 3, is similarly provided with a corresponding set of a ertures 5, for the reception of the upper encs of the pivotal bearings. These apertures are of peculiar shape, as illustrated in Fig. V, in that the circular aperture 5, is a vertical one, extending directly through the ledge, and of a size suitable to receive one of the ivotal bearings, but provided with a beve ed enlargement 7, on the under side, and a corresponding oppositely inclined beveled enlargement 8, on the upper side, whereby when a pivotal bearing is to be removed, its lower end after being unseated, may be drawn forward a sufficient distance to clear the lower ledge without bending the upper end within its receiving aperture.

For the purpose of simultaneously looking all of the swinging leaves in place, a locking shelf 10, is provided, which is hinged to the back at 11, and which, when swung to its horizontal position, rests upon the top of all of the pivotal bearings, preventing them from being sufliciently raised through the ledge 3, to allow the lower bearing pivot to be unseated from its socket. In order to secure this locking shelf against unauthorized interference, a lock 12, is provided, the bolt of which engages a staple-shaped keeper 13, fast to the ledge 3, so that only one pro-= vided with the key to this look can render the shelf capable of swinging up sufficiently to permit the removal of the leaves from their bearings in the ledges.

Each leaf consists of a light but strong framework, 20, preferably rectangular, and provided with interior strengthening rods 21. The inner vertical edge of this frame work is prolonged in a downward direction to form the bearing pivot 22, and in an upward direction to form the locking pivot 23 the vertical height of the leaf being suificiently less than the distance between the ledges 2, and 3, to permit the leaf to be raised between the two until the lower or bearing pivot is unseated. The inner edge of the framework is also recessed at 25, in order to facilitate the grasping of the cards or other objects which are to be displayed. For the reception and securing of these cards, the three exposed edges of the frame are provided with flanges 27, attached to the frame and with their overlapping edges projecting a short distance rearwardly with interposition of a sufficient space to receive a card of the thickness which it is proposed to display upon the leaf. On the inner edge marginal strips 28, are similarly mounted. By this arrangement Whenever a leaf is removed from the stand, two cards 29, 29, may be slid beneath the margins 28, and under the flanges of the other ledges, and thus be secured one on either side of the swinging leaf for purposes of display. In operation when cards, sheets, time-tables,

photographs or other objects are mounted upon the leaves, the latter are all secured within their bearings in the shelves and so remain under lock and key until one rovided with the key unlocks the locking s elf and by removin one or more of the leaves slips out the car s or other displayed objects and replaces them with others. It is obvious that except whenthus removed, the displayed cards are fixedly held within their mountings on the leaf and cannot be wrongfully removed.

If desired, a protecting sheet of glass or celluloid 29 may be slipped with the card into the frame.

Having thus described my invention, I claim:- 7

1. A display device comprising rectangular leaves, fixed pivotal bearings coincident with one of their edges, a stand for mounting said leaves consisting of two horizontal spaced ledges, the lower led e being provided with socket bearings for the lower ends of the pivots, and the upper ledge being provided with corresponding bearing holes- 2. A display device comprising one or more rectangular display leaves with piv-,

otal bearings coincident with one of the edges thereof, two horizontal ledges suitably spaced; sockets in the lowermost ledge; vertical bearing holes in the upper ledge with beveled enlargements which permit the inclination of the pivotal bearings within bearing holes prior to their removal.

In testimony whereof, I have hereunto signed my name, at Philadelphia, Pennsylvania, thistwenty-fourthday of April 1908.

ALFRED M. PARKS.
