TRANSPARENCY.

SPECIFICATION formng part Of Letters Patent NO. 403,698, dated May 21, 1889.

Application filed November 19, 1888. Serial No. 291,212x (No model.)

To aZZ whom it may comem..-

Be it known that I, HENRY C. REcToR, a

citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Transparencies; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a transparency or banner, and has for its object to provide a device of this nature that can be readily folded to economize space in storing and faeilitate its transportation, and which can be adjusted to compensate for the shrinkage or give in the fabric, so as to maintain the fabric in a stretched condition when the banner is in use.

Afurther object of the invention is to provide a device for the purposes hereinbefore stated which will be simple, cheap, compact, and which will be light and easily handled.

The improvement consists in a staff or pole, two collars, one or both movable on the staff or pole, frame-bars for supporting the fabric, and rods pivotally connected With the ends of the frame-bars and with the said collars.

The improvement further consists of t/he peculiar construction and the combination of the partsnvhich will be hereinafter more fully described and claimed, and which is shown in the annexed drawings, in which- Figure 1 is a perspective view, parts being broken away, of a transparency or banner embodying my invention; and Fig. 2, a perspective view showing the device folded.

The collars or heads A and B, mounted on the staff or pole C, have the inner ends of the upper and lower sets of rods, D and E, respectively pivotally connected therewith.

The frame-bars F have their upper ends pivotally connected with the outer ends of the rods D and their lower ends pivotally connected with the outer ends of the rods E. The fabric G, stretched around and socured to the frame-bars, forms the sides of the banner.

The operation of the device is as follows: By sliding one or the other or both of the collars on the staff or pole, so as to bring them closer together, the outer ends of the rods l) and E Will be forced out-Ward from the pole, carrying the frame-bars with them and distending the fabric. This operation is continued until the fabric is stretched suffi ciently, When the movable collar is made fast to the staff or pole by suitable means, preferably by the set-screw h. If the fabric should shrink and the parts be strained too much and in danger of injury, the set-screw can be loosened and the collar moved to bring the frame-bars into closer relationship, thcreby relievng the fabric of the undue strain. On the other hand, if the fabric should give and become too loose, a movement of the collar in the proper direction will separate the frame-bars and take up the looseness and stretch the fabric. By separating the collars or moving one or both on the pole or staff in the proper direction the rods D and E and the framebars will be brought close to the said staff or pole, and, the fabric bein'g wrapped around the frame-bars and the pole, the device will be reduced and assume the form substantially shown in Fig. 2. A

The form. of the banner depends upon the -number of the frame-bars, the relative length of the rods D and E, andthe manner of securing the fz brie to the frame-bars. Eithcr one or all of these features of construction can be resorted to to obtain the required form of banner; as will be readily understood.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, ls-

1. A folding banner or transparency composed of a pole, frame-bars, and rods connecting each end of the frame-bars with the pole, substantially as described.

2. A folding banner or transparency composed of a pole, frame-bars, the heads on the pole, and the rods pivotally connected with the heads and with the upper and lower ends of the frame-bars, substautiaily as set forth.
