STAND FOR PHOTOGRAPHS. v
SPECIFICATION forming part of Letters Patent No. 518,073, dated April 10, 1894. Application filed March 18, 1893. Serial No. 466,653. (No model.)
To all whom it may concern.-
' Be it known that I, ARTHUR D. F. RAN- DOLPH, a citizen of the United States, residing at New Yorkcity, in the county and State of New York, have invented a certain new and useful Improvement in Stands for Photographers, of which the following is a specification.
The present invention is an appliance for photographersuse, being a stand to support a developing tray, forming part of a portable outfit which forms the subject matter of two applications for United States Letters Patent filed by me of an even date herewith, Serial Nos. 466,655 and 466,654, respectively. To successfully use the developing tray and the dark room forming the basis of the aforesaid applications it is necessary to have the same supported at a distance above the table, or other convenient support on which they may be placed so that the under side of the dark room is readily accessible for convenience in performing the several operations incident to changing the plates from the plate-holder to the developing tray, and light will be admitted beneath the developing tray to permit observation of the developing process.
With these ends in view the invention consists of a stand, composed of a top, which is adapted to embrace the sides of the tray, and havinga supporting-ledge, and folding leg sections, the latter being braced to give the required stability to the structure.
The invention further consists of the novel features and the peculiar construction and combination of the parts which will be hereinafter more fully described and claimed and which are shown in the annexed drawings, in which- 7 Figure 1 is a perspective view of a stand embodying my invention. Fig. 2 is a detail section showing the developing tray in position. Fig. 3 is a bottom plan view showing the legs folded.
The top of the stand is composed of vertical sides B which are designed to embrace the sides of the developing tray 0 and retain the latter in place, and an inner ledge A to extend beneath and support the said tray. The vertical sides B and the ledge A are preferably integrally formed, being constructed of sheet metal which has its lower edge bent inward to form the part A. The legs D are legs are connected in pairs by the cross bars n constituting leg sections. These leg sections are held open when unfolded by braces I and J, which are pivotally connected at opposite ends to the cross bars 91 of the respective leg sections. The free end of the brace J is adapted to interlock with the free end of the brace I when the leg sections are opened, by a spring catch or snap j on the brace J engaging with the closed end of the brace I. The brace I is formed from a stout wire or rod which is doubled on itself, and the brace J is a single rod or stout wire and adapted to fold between the parallel members of the brace I, as shown in Fig. 3.
Having thus described my invention, what I claim, and desire to secure by Letters Patout, is-
1. A stand for photographers having folding leg sections, catches to hold the said leg sections in a folded position, and braces I and J having their outer ends pivotally connected with the cross bars of the said leg sections, the brace I being a folded rod, and'the brace J being a single straight rod and having a catchj on the inner end to engage with the folded end of the brace I, substantially as described.
2. The herein shown and described stand for photographers, composed of a top having vertical sides and an inner ledge, folding leg sections having their lower ends expanded, catches to hold the said leg sections in a folded position, and braces I and J pivotally connected at their outer ends to the cross bars of the leg sections, the brace I being a folded rod and the brace J a single straight rod having a catch at the outer end to engage with the folded end of the brace I, substantially as specified for the purpose set forth.
This specification signed and witnessed this 15th day of March, 1893.
