Patented Nov. 21, 1950 BULLETIN SHEET HOLDER AND SUPPORT Calvin Glenn Hubbell, Rankin, I1l., assignor to 0. Howard Hunt Pen 00., Camden, N. J., a corporation of New Jersey Application August 20, 1945, Serial No. 611,615
This invention relates to holders or clamps designed for use in removably holding and supporting bulletin sheets, maps or the like, in an extended position, so that they may be conveniently viewed and examined.
An important object of the invention is to provide a device of this character wherein the bulletin, map or article supported thereby may be readily and easily slid into position and held by frictional contact with the movable blade thereof, eliminating the necessity of piercing the bulletin or article supported thereby, as is usual in hanging bulletin sheets on the well known bulletin supports now in use.
Another object of the invention is to provide a bulletin support, wherein the clamping means may be readily operated to release the sheet, when it becomes necessary to remove and replace the sheet.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawing Figure 1 is an elevational view of a support constructed in accordance with the invention.
Figure 2 is a vertical sectional view through the support and illustrating a sheet as positioned therein.
Figure 3 is a vertical sectional view through a modified form of support.
Referring to the drawing in detail, the support or holder comprises a body portion 5, which is formed with openings for the reception of screws 6, whereby the body portion may be secured to a supporting surface.
As shown by Fig. 2, the body portion is formed with a flange I which extends along the upper edge thereof, the outer surface I of the flange 1 being beveled.
The reference character 8 designates the blade-supporting plate of the device, which is secured to the flange I, by the nails 9. Because the upper surface of the flange l is beveled, it will be seen that the plate 8 is disposed at an oblique angle with respect to the body portion 5.
The lower edge 8 of the blade-supporting plate 3 provides a surface In against which the blade ill rests, the blade It being secured in position by the strip l i which is held in place by the securing members [2.
The blade It is constructed of flexible material, such as rubber or the like, and is of a width to extend across the space between the body portion 5 and blade-supporting plate 8, so that when a sheet, such as indicated at A in Fig. 2 of the drawing, is positioned against the body portion and forced upwardly under the blade H], the weight of the sheet will, when released, draw the blade l0 downwardly setting up a binding action between the blade, the body portion and sheet A.
Should it be desired to release the sheet A, it is only necessary to press the blade l0 upwardly, whereupon the sheet A may be withdrawn.
In the modified form of the invention as shown by Fig. 3 of the drawing, the support comprises a body portion l3 and an overlying blade supporting member M formed by bending a length of sheet metal material upon itself. One edge [4' of the blade supporting member 14 is bent upon itself to provide a clamp l5 for clamping the blade l5, which is constructed of suitable semi-rigid material, such as rubber or the like. In this form of the invention, the bulletin or sheet to be supported by the device is forced upwardly between the blade l5 and body portion [3. The weight of the sheet will draw the blade downwardly and the frictional contact of the blade with the sheet, will support the sheet in an extended position.
While I have shown and described the device as constructed of wood or sheet metal material, it is to be understood that any suitable material, such as plastic or the like, may be used in the construction of the device, without departing from the spirit of the invention.
What is claimed is:
A bulletin sheet holder and support, comprising a body portion adapted to be secured to a supporting surface, a blade supporting member extending from the upper end of said body portion and overlying the main portion of the body in spaced relation therewith, an upwardly inclined flexible blade constructed of rubber-like material secured to the blade supporting member, the flexible blade extending across the space between the blade supporting member and main portion of the body, the free edge of the blade resting against the main portion of the body at a point below the level of the top of the blade supporting member and adapted to grip an article placed therebetween.
