Patented Jan. 12, 1932 PATENT OFFICE HENRY S. GREENSTONE, DE LOS .ANGELES, CALIFORNIA DISPLAY, DEVICE Application filed June 27,
This invention relates to an alluminated display device adaptedto display in an advantageous manner advertising matter, pictures, and various other matter which it is desired to vary from time to time.
An object of the invention is to provide improved resilient means for removably sustaining a. series of bars or other supporting members which are designed to hold the placard upon which letters, pictures, et cetera, may be inscribed in position for illumination and for convenient inspection.
Another object of the invention is to improve various details of construction of devices of the kind stated with regard to simplicity of construction, low cost of manufacture, and convenience of assembling.
Still another object of the invention is to provide an illuminated display device wherein a translucent face plate will be combined in a more advantageous manner, not only with the bars which support the letters or other matter to be displayed, but also with novel springs of a simplified and improved construction to retain the bars removably in an operative position.
Other objects, advantages and features of the invention may hereinafter appear Referring to the accompanying drawings which illustrate what is at present deemed to be apreferred embodiment of'the invention V Fig. 1 is a vertical section of the device taken on line 11 of Fig. 2.
Fig. 2 is a front elevation of the device.
1 Fig. 3 is a transverse section taken on line 3-3 of Fig. 2.
Fig. 4: is an enlarged vertical sectional de tail'taken on line 44 of Fig. 1.
Referring in detail to the drawings, the casing 7 is of aquadrilateral character as viewed in cross section and having the comparatively narrow rear wall 8, side walls 9 and a face plate 10 which is disposed oppositely to the back or rear wall 8, said face plate being composed of transparent or translucent material. The face platelO, preferably of a rectangular form, is shown pro- I vided along each of its four sides with a moldi fing 14, the vertical portions of said molding 1931. Serial No. 547,320.
being provided witha groove or recess 15 which extends along the outer face of each vertical margin of the face plate 10. Withineach. of said grooves 15 is seated a leaf spring 16 which is adapted to releasably sup- '55 port a series of transversely extending placard-supporting bars 18.
As well shown in Fig. t each leaf spring 16 is so bent as to provide therein a series of spaced seats 20 which is adapted to receive an end portion of any one of the bars 18, and at each side of each seat 10, said spring is provided with a rise 21. Midway between each of the seats 10 the leaf spring 16 is bent to a greater depth as indicated at 22, these deep po tions of the spring being designed to r upon the edge portion of the molding 14-. at the bottom of the groove 15 thereof. At these points the leaf spring 21 is preferably secured to the molding by any suitable attaching device such as the tacks or small nails 25.
Each of the placarcbsupporting bars 18 is provided at its opposite edges with a groove 27 which is adapted to receive an edge portion of one of the placards 45. Owing to the fact that the seats 20 of each spring 16 are not so deep as the intervening seats 22, a clearance 30 is provided between the spring opposite each seat 20 and the adjacent edge of the molding as is clearly shown in Fig. 4. This clearance 230 permits the spring to be sprung down opposite such clearance whenever it is desired to insert or remove the end portion of the bar 18 which is to be supported 35 in said seat. T he placard-supporting bars 18 are resilient and are relatively narrow and therefore can be sprung sufiiciently in an edgewise manner to permit insertion of they placards between them after said bars have 99 been mounted with their end portions occupying the seats 20. The resiliency of the bars 18 also aids the operator in springing the end portions of said bars into the seats provided for them.
Referring to certain details of construction, the casing 7 is. provided with a door 35 to admit the lamp globes '36 which are mounted inside the casing over lamp sockets 38 111 any well known approved manner. The device is provided with a ventilating opening 40 in its upper end wall 41, said ventilating opening preferably being covered'by a shield 42 in spaced relation thereto.
The leaf spring 16 is shown as a relatively narrow strip of resilient material being so bent that the seats 22 and 20 extend from edge to edge thereof and the wallsateach side of these seats extend at substantially a right the face plate while a small placard 46 is located in the upper portion thereof and also another smaller placard in the lower portion of the face plate. By providing a con-.
siderable number of seats 20 formed in the springs 16 in properly spaced relation to each other, a greater variety of adjustments may be obtained with regard to the spacing of the placard supporting bars 18.
The display device provided by this invention is not limited to the illuminating feature, but may be used independently thereof to support placards on billboards or in the directories of oflice buildings.
1. In a device of the kind described, a casing having a translucent face plate, illuminating means within said casing to direct light through said face plate, a leaf spring extending along a marginal portionof the outer face of said face plate, said spring having a series of spaced seats therein, and a plurality ofbars having end portions adapted to spring into said seats. 7
2. In a device of the kind described, a casing having a translucent face plate, illuminating means. within said casing to direct light through said faceplate, an upwardly and downwardly extending leaf spring located at each vertical margin of said face plate, each of sald springs having a plurality of seats the bottom portions of which are &
directed away from the central portion of the face plate, and a plurality of bars adapted to support placards, said bars each having ing, a spring extending upwardly and downend portions which are adapted to be sprung into and out of said seats.
3 In a device of the kind described, the combination with a face plate and'means for directing light therethrough; of a retaining spring mounted to extend along a marginal portion of said face plate, said spring consisting of a relatively narrow strip of resilient material, which is provided with a series of bends thereby forming in said strip a series of seats which extend across the entire width thereof.
4. In a device of the kind described, the 54 combination with a face plate and means for directing light therethrough; ofa retaining spring mounted to extend along a marginal portion of said face plate, said spring consisting of a relatively, narrow strip of re- '51 silient material, which is' provided with a series of bends thereby forming in said strip a series of seats which extend across the entire width thereof, relatively deep seats alternating with relatively shallow seats in said 51 a series of seats, relatively deep seats alternating with relatively shallow seats in said series, and fastening means whereby said spring is secured in place in such a manner as to permit fiexion of the portions thereof} containing said deep seats.
6. In a device of the kind described, the combination with a face plate;'of means extending vertically across said face plate and provided with a series of seats located at op i posite margins of said face plate, and a series of placard-supporting bars having grooved edge portions, said bars being resilient to permit them tobe deflected in an ,edgewise manner to receive the placards in the grooves- E thereof, the end portions of said bars being adapted to be Supported in said seats.
7. In a device of the kind described, the combination with a pair'of cooperating'supporting members which extend in substantialfi parallelism'toeach other and each of which has a series of seats facing the other, of a set of placard-supporting bars which have longitudinally extending seats adapted to receive placards, the end portions of said bars' f being adapted to engage said seats, said sup porting members being resilient,'and said placarchsuppor'ting bars also being resilient, thus adapting said bars to have their end portions sprung into and out of the seats of said supporting members.
8. In a device of the kind described, a caswardly along a marginal portion of said casing, said spring havinga series of spacedi shoulders which are directed toward the midwidth of the casing, and a plurality of bars having end portions adapted to rest upon said shoulders, the resiliency of said spring permitting said shoulders to be forced out-" wardly for the insertion of said bars in position to be supported by said shoulders.
