LEONIDAS H. PUMIVIILL, OF HARTWELL, OHIO.
Specification of Letters Patent.
Patented Oct. 27, 1 9141.
Application f11ed December 11, 1912. Serial No. 736,139.
To all whom it may concern Be it known that I, IJEONIDAS H. PUM- MILL,a citizen of the United States of America, and resident of Hartwell, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Advertising Devices, of which the following is a specification.
This invention relates to advertising devices and has for an object to produce an improved collapsible display sign, of the type illustrated, which is cheaper to build and at the same time more durable than similar signs or advertising devices known to me.
This and other objects I attain by means of an advertising device illustrated in the drawings accompanying and forming a part of this application.
In the drawings Figure 1 is a perspective View of anAshaped collapsible sign embodying my invention. Fig. 2 is a plan view of a sheet metal blank which is employed in the construction of the sign illustrated in Fig. 1. Fig. 3 is a fragmental section along the line 33 of Fig. 1. Fig. 4: is a perspective view of a modified form of sign embodying my invention. Fig. 5 is a plan view of the sheet metal blank employed in constructing the sign illustrated in Fig. 4. Fig. 6 is a fragmental sectional view along the line 6-6 of Fig. l.
The sign, illustrated in Figs. 1, 2, and 3, includes a metal sheet 7, which is bent to form two oppositely disposed display faces 8, and which is also rolled so as to form lateral stiffening flanges 9. The stiffening flanges are formed from longitudinally extending extensions 9, two of which are provided on each side of the sheet metal blank 7, and are separated by a laterally projecting tongue 10.. The tongues 10 on opposite edges of the blank are, located across from each other and midway betweenthe ends of the blank.
In the sign illustrated, two braces 12 are employed, one being located between the ads acent flanges 9 on one side of the sign and the other being similarly located on the other side of the sign. Each brace consists of what is known as a knuckle break back, with the hinge located midway between its ends. The knuckle 13 is so located on one of the hinge members that it engages the other member when the members are moved to an alined position. The knuckle is also located on the upper side of the brace, so that it prevents the brace from collapsing, due to its own weight.
The operation of constructing the sign illustrated in Fig. 1 consists in rolling or otherwise forming the extensions 9 into the flanges 9, then bending the metal sheet so as to form two transversely extending creases 1et-1+, one of which is located on each side of the projecting tongues 10 and i then bending the tongues downwardly, so
that each covers the upper ends of the flanges 9. The legs may be inserted into the outer ends of the flanges at any suitable time during the construction of the sign and the braces 12 may be mounted on the sign after the legs are in place. InFig. 1 I have also illustrated the sign as being provided with a narrow stiffening flange 15 along:
each of the lower edges of the metal sheet 7. This is formed by bending the projecting ends of the metal blank back against the inner or under face of the blank.
In Fig. e1: I have illustrated what I now consider to be the preferred form of my invention. It consists of a collapsible sign similar to the sign illustrated in Fig. 1, in which the display portions, the stiffening flanges and the logs are formed from a single sheet of metal. As illustrated, the sign consists of oppositely disposed display faces 16, and lateral flanges 17 which are cylindrical in shape and which are continued below the lower edges of the display faces and thereby form supporting legs 18 for the sign. The lower edge of each display face i bolts 22, which extend through one side only of their mounting flanges and which are provided with nuts, located within the interiors of the flanges.
The blank illustrated in Fig. 5 and from which the sign illustrated in Fig. 1 is formed, is provided with longitudinally extending lateral extensions, 18, two of which are located on each side of the blank. The extensions 18 on each side of the blank are separated by means of the tongues 21, which are formed integrally with the blank and project laterally thereof. The tongues, like the tongues 10 of the blank illustrated in Fig. 2, are located opposite to each other and midway between the ends of the blank. The blank is also provided with a partially severed portion 19 at each end and between the outer ends of the extensions 18.
The operation of forming the sign consists in rolling the extensions 1 to form the lateral flanges and the legs of the sign, rolling the partially severed portions 19 to form the transversely extending stiffening flanges 19 and then bending the sheet along transversely extending creases located on each side of the tongues 21. After the sign is formed the braces 12 may be secured in place and the tongues 21 bent downwardly.
With either of the constructions illustrated, a sign is produced which is cheap to manufacture, is light, strong and durable and which can be collapsed so that it is substantially flat.
It will be understood, that the flanges 17 andthe legs 18 may be of any desired shape and that means other than the braces 12 may be employed for holding the opposed display faces of the sign in the proper relative positions, when the sign is located in an upright position.
' In accordance with the United States patent statutes, 1 have illustrated and described the preferred embodiments of my invention, but I desire it to be understood that various changes, modifications and substitutions may be made in the signs illustrated, without departingfrom the spirit and scope of my invention as set forth in the appended claims.
l/Vhat I claim is:
1. A sign of the character described, comprising a single sheet of metal bent to form oppositely disposed display portions and having integrally formed flanges and integrally formed tongues for covering adjacent ends of the flanges, said display porcents each, by addressing the Commissioner of- Patents,
' prising, a single sheet of metal, bent to form oppositely disposed display portions and lateral flanges, tongues formed integrally with the sheet and located between adjacent lateral flanges, and legs mounted on the ends of the sheet in alinement with the flanges, said display portions being movable from relatively inclined positions to closed parallel po- 5 sitions around transversely extending creases formed on either side of said tongues.
3. A s1gn of the character descrlbed, comprising a single sheet of metal bent to form 1 oppositely disposed display portions having lateral flanges and supporting legs integrally formed therewith.
1. A. sign of the character described, com prising, a single sheet of metal bent to form lateral dances and legs located at one end of the sheet and integral with the flanges.
5. A. sign of the character described, comprising a single sheet of metal bent on paral lel creases to form oppositely disposed dis play portions and having integral flanges and supporting legs formed thereon, and 0ppositely disposed metal tongues out therefrom, located between the creases and bent downwardly to cover the upper ends of the flanges;
6. A. sign of the character described, comprising a single sheet of metal bent to form oppositely disposed display portions and having its edges bent to form stiffening flanges and supporting legs integrally formed therewith, tongues cut from opposite edges of the metal and bent to cover ad acent ends of adjacent flanges and a hinged brace secured to adjacent lateral flanges.
7. A. sign of the character described comprising a single sheet of metal bent on par allel creases to form oppositely disposed display portions having tubular lateral flanges inte rally formed therewith, and legs for the device secured to and extending axially of said tubular flanges.
In testimony whereof, I have hereunto subscribed my name this seventh day of December, 1912.
