UNITED STATES PATENT OFF-ICE.
JOSEPH W. C. SHIPMAN, OF LOS ANGELES, CALIFORNIA.
APRON FOR PHOTOGRAPHIC DEVELOPING EQUIPMENT.
Application filed .Tune 17,
To all whom it may concern:
Be it known that I, JOSEPH W. C. SH P- MAN, a subject of the King of Great Britain. residing at Los Angeles, in the county of Los Angeles, State of California, have invented a new and useful Apron for Photographic Developing Equipment, of which the following is a specification.
My apparatus relates to the art of photography, and more particularly to the art of developing and fixing the photographic image. In this art it is common practice to produce an image on a sensitized film or paper, this film or paper then being subjected to the action of suitable developing, fixing and washing solutions for the purpose of fixing the image previously produced.
The object of my invention is to provide an apron by which such film, paper, or the like, hereinafter referred to as photographic material, may be rapidly and efficiently handled for the purpose of so developing and fixing the image.
Further objects and advantages will be set forth in detail hereinafter.
Referring to the drawings, which are for illustrative purposes only:
Fig. lis a plan view of the spacing apron. Fig. 2 is an edge View of same.
Fig. 3 is an edge view showing relationship between the photographic material and the drying apron.
In the drawing I show a portion of photographic material which may be either a length of film or sensitized paper. In subj ecting such photographic material to development processes, it is essential that the separate layers or thicknesses of the paper, when rolled upon a drum, shall be kept spaced apart so that free access of liquids may be provided thereto. The apron 40 provides a series of blocks 41 which are arcuated in form and which are connected together in pairs by laterally extending bars 42, the bars with blocks attached to the ends thereof being linked together in consecutive arrangement by link members 43 which flexibly engage loops 44 extending from the ends of the blocks 41.
In Fig. 3 of the drawing I show the man- 1919. Serial No. 305,698.
ner in which a sheet of absorbent material 45 may be wound upon the apron 40 with the photographic material 30, in order to facilitate the drying thereof. The blocks 40 being of arcuated form, as shown, may be wound spirally into a roll and are of sufficient thickness to hold the bars 42 spaced apart so that the consecutive layers of material wound upon the bars will not come into engagement, and further provide spaces into which development solutions may enter and come in contact with the surfaces of the photographic material 30.
I claim as my invention:
1. In an apron for separating the successive turns of a roll of photographic material upon a reel, comprising: axially disposed rods of proper length to accommodate the width of said photographic material to be wound thereupon; blocks of proper thickness to separate said turns mounted upon the ends of said rods; and hinged links connecting said blocks at right angles to said rods.
2. In an apron for separating the successive turns of a roll of photographic material upon a reel, comprising: axially disposed rods of proper length to accommodate the width of said photographic material to be wound thereupon; blocks of proper thickness to separate said turns mounted upon the ends of said rods, said blocks being arcuated to conform to the spiral which they assume when wound between said turns of photographic material; and hinged links connecting said blocks at right angles to said rods.
3. In an apron for separating the successive turns of a roll of photographic material upon a reel, comprising: axially disposed rods of proper length to accommodate the width of said photographic material to be wound thereupon; blocks of proper thickness to separate said turns, mounted upon the ends of said rods; loops oppositely extending from said blocks; and links connecting between said loops so as to form a chain structure therewith.
4. In an apron for separating the successive turns of a roll of photographic material upon a reel, comprising: axially disposed rods of proper length to accommodate the 100 Width of said photographic material to be Wound thereupon; blocks of proper thickness to separate said turns mounted upon the ends of said rods, said blocks being arc- 6 uated to conform to the spiral which they assume when Wound between said turns of photographic material; loops oppositely extending from said blocks; and links connecting between said loops so as to form a chain structure therewith.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 10th day of June, 1919.
JOSEPH W'. G. SHIPMAN.
