Description
. ROBERTM. LINN, OF LOOKOUT MOUNTAIN, TENNESSEE.
IMPROVEMENT IN PHOTQGRAPHIC FILTERING APPARATUS.
Specification forming part of Letters Patent No. 119,375, dated September 26, 1871.
To all whom it may concern.-
Beit known that I ROBERT M. LINN, ofLookout Mountain, in the county of `Hamilton and State of Tennessee, have invented certain Improvements in Photographic Filtering Apparatus, of which the following is a specification:
The iirst part of my invention relates to the combination of a photographic dipping-bath for holding' silverin solution and a linieumatic arrangement firmly clamped upon the top of the bath-cup, and operated in a manner to compress the air above thesolution and cause it to be discharged through a tube into a funnel or reservoir. The second part of my invention relates to the use of a filtering-bowl and for the purpose of filtering in a thorough and convenient manner the silver solution back into the bath-cup.
`Figure I is an end elevation of the machine embodying my invention, and shows the position for ltering; the dotted lines give the position when transferring the solution to the iiltering apparatus.' Fig. II is a plan of the compressing arrangement. Fig. III details more clearly the parts and construction of the compressing' apparatus. Fig. IV showsthe construction of the iiltering-plug.
A is the base, which should be constructed of wood, upon which should be attached the supporting-arms B, the post J, and the box U C containing the bath-cup D. These parts should be made of iron or'brass, in a light but substantial manner. G is the filtering-bowl, which should be large enough to hold the contents of the bathcup, and should be made of glass, photographic ware, or hard rubber, or any iirm substance that will not contaminate the silver solution. It is to be made, as shown at c, to receive the filteringplug and to prevent the sediment from clogging' the filtering material. K is a metal ring attached to the arm B for supporting` the iiltering-bowl. I is a glass or hard-rubber funnel, to convey the solution into the bath-cup. F are bellows for compressing the air, to be made of strong pliable leather or vulcanized rubber. S is a grooved block, upon which the leather or rubber is attached. T shows a binding-strip, nailed in the groove S and binding the bellows firmly to theV block to make the joint air-tight; it should Vbe cemented with, glue, varnish, lead, or putty. Z is a slotted double arm for actuating the bellows. N is a strap valve. E, the lower bellows-block, with grooves on the face of' it of the form shown at u, and extending around the edges of it to conform to the exact shape of the top of the bathcup. His a exible plate of rubber, attached to the block for the purpose of iirmly and closely packing the point of contact with the top of cup, and thus rendering it air-tight, and the grooves are intended, also,to firm ly support the top of the cup from the pressure of the air. d is a packingjoint for the tube fr. M is a valve, of wood or other material, vwith a flute-like hole; this is to be covered with the soft-rubber strap C or band of suitable tension. R is a compression-loop, of metal, so constructed as to lessen or increase the tension with a screw-eye. Q is a catch, of'metal, sloped and fastened on the end of the bellowsblock E, for holding the compression-loop It. V is a tube for conveying the solution' to filter, and should be made of glass or hard rubber. Wis a iiltering-plug, to be made of glass, hickory, or rubberand provided with the shoulder X, and capped with a band of soft rubber to shut the opening of iiltering-bowl, and wrapped with cotton, as represented at Y and Z.
I claim as my invention* l. The combination of the compressing vapparatus Fand E with the photographic bath-cup D, substantially in the manner and for the purpose hereinbefore set forth.
2. The construction and arrangement of the arms B, supports z, posts T, and the ring K.
3. The construction of the filtering-bowl in the manner and of the material, as described, with the attachment a at the bottom.
4. The discharge-pipe V, of rubber or glass, and the method of inserting it through rubber. packing, as at d.
5. The valve M, in combination with a rubber strap or band and tension-cord P.
6. The valve-strap N, when used for the purpose hereiubefore set forth.
7. The bellows F, made and used substantially as hereinbefore set forth.
8. The grooved blocks E and S, and the manner of binding the material to the same, as repesented at S aud T, and the groove S and U, .ubstautially in the manner and for the purpose 1ereubefore set fort 9. The eXble-rubber plate H, for the purpose lereinbefore set forth.
l0. The slotted double arm b, for the purpose hereiubefore set forth.
l1. The adjustable clamping device, substantially as and for the purpose hereubefore set forth.
