FRAME FOR HOLDING SIGNS.
I SPECIFICATION forming part Of Letters Patent No. 758,088, dated April 26, 1904.
I Application filed October 23, 1903. Serial No. 178,267. (No model.)
To (Z whom it may concern:
Be it known that I, CURTIS Gr. MIXER, a citizen of the United States, residing at Muskegon, in thecounty of Muskegon and State of Michigan, have invented certain new and useful Improvements in Frames for Holding Signs, of which the following is a specification.
The object of'this invention is to produce a substantial metallic frame for holding signs, susceptible of being transported in a knockeddown condition to the place where it is to be set up, also provide an opportunity of conveniently removing the signs. from frame and replacing others.
In the accompanying drawing is shown an isometrical representation of my improved sign-board.
Each end is composed of two angle-iron bars, each having a vertical portion 1 and leg portion 2, connected at their upper ends by the horizontal angle-iron bars 3. The lower ends of the leg portions are connected by angle-iron bars 4, which hold the uprights from separating. At intervals in the length of the vertical bars are located bars 5, 6, and 7, forming a groove 8 along the top edge anda groove 9 along the bottom edge. Bolts or rivets connect these bars with the vertical sections of the frame.
When the frame'is set up, the brace-bar 4; is buried in the ground, which will hold the frame in an erect position. A channel-bar 10 is secured, in connection with the vertical bars, at one end of the frame, which closes up one end of the grooves. Within the grooves are located steel panels 11, upon which may be painted advertisements. These panels being removable from the frame, the advertisements may be painted upon them at the factory and the panels carried to where the frame is located and placed in the grooves of the frame. To the lower edge of the vertical bars at one end of the frame is pivoted a channelbar 12, which may be turned up over the ends of the panels 11 and secured in connection with the vertical bars. This channel-bar holds the panels from being removed from the frame without authority.
It is evident that a single panel might be employed instead of the four shown in the drawing and still be within the scope of my invention.
I claim as my invention A frame comprising two like ends, each end composed of two vertical angle-bars having continuations forming legs, a brace-bar connecting the lower ends of the legs, a series of three strips each connecting the two ends, the center strip being of less width than the two outside strips thereby forming a groove, a panel located in thegroove, a channel-bar receiving the frame of one end and permanently connected thereto, a channel-bar having a pivotal connection with the frame of the other end and adapted to receive the frame'of that end, and brace angle-bars located at the upper edge of the ends.
