234 THE PHOTOGRAPHIC NEWS. PRIL 13, 1883. Patent Jntelligence. Application for Letters Patent. 1787. Lucy Wise, of Clifton, near the city and county of Bristol, for an invention of “ Improvements in receptacles or albums for rendering them capable of containing crystoleum paintings.” —Dated 9th April, 1883. Grants of Provisional Protection. 1095. James Weaver Tattersall, of Accrington, in the county of Lancaster, Photographer, for an invention of “ Improve ments in apparatus for washing photographs.”—Dated 28th February, 1883. 1229. Alfred Horace Dawes, of Brook Cottage, Windermere, in the county of Westmorland, Artist, for an invention of “An improved process, system, or method of producing per manent coloured photographic card pictures.”—Dated 7th March, 1883. Patents Void through Non-payment of Duties. 1303. William Robert Lake, of the firm of Haseltine, Lake, and Co., Patent Agents, Southampton Buildings, London, for an invention of “ An improved apparatus for holding and ex hibiting photographic or other pictures, and the like.”—A com munication to him from abroad by Theodor Muench, of Vienna, Austria.—Dated 30th March, 1880. According to the said invention, the frames for holding the photographs, drawings, pictures, or other flat objects, are each mounted on pivots in a rectangular holder, in such a manner that each of the said frames can be turned on its pivot through an angle of about 120 degrees. The frames may be of metal and cardboard, whilst the pivots for the separate frames, as well as the rectangular holder, are by preference made of metal, and the said rectangular holder may be arranged to slide into grooves in the opposite sides of a suitable box or case, so that it can be easily removed or exchanged. Such boxes or cases are by pre ference made of wood, and may have any fanciful form, and be constructed so as to receive any suitable number of the holders. I wish it understood that I claim,— First. In an apparatus for holding and exhibiting pictures, the open holder provided on two of its opposite sides with a series of pivot-bearings in combination with frames, each of which is provided at or near its lower edge and on opposite sides with pivots arranged within the said holder, all constructed and operating substantially as set forth and for the purpose specified. Second. The combination of the holder and its pivotted frames with a case provided with the inclined groove for the reception of the said holder, all arranged, constructed, and operating as set forth and for the purpose specified. Third. The combination of the holder and its pivotted frames with a wheeled case having the inclined groove, all constructed, arranged, and operating substantially as set forth for the purpose specified. 1305. William Robert Lake, of the firm of Haseltine, Lake, and Co., Patent Agents, Sonthampton Buildings, London, for an invention of “ Improvements in and relating to woven fabrics with photographs thereon, to preserve the same and fit them for the application of oil colour.”—A communication to him from abroad by the firm of Wilhelm M. L. Winter and Company, of Vienna, Austria.—Dated 30th March, 1880. This invention relates to woven fabrics on which positive photographic pictures have been produced by any appropriate method, such for instance as that described in the specification of former letters patent, dated 31st March, a.d. 1877, No. 1264 ; and the said invention has for its object the preparing or treat ing of the said woven fabrics in such a manner that they will be protected from the action of damp, air, and from other atmo- spheric influences, and will be in a proper condition for receiving oil-colour on their surface. The process for treating the said fabric for the purposes described is as follows, that is to say :— The fabric is stretched on a suitable frame and coated with wax ■or equivalent fatty substance on the front or picture surface un til it appears entirely smooth and compact. After the coating of wax has become hard, the other or reverse side of the fabric is coated with varnish, the latter combining with the wax which has penetrated the fabric. By this process the fabric is effectually protected from atmospheric influences ; it is rendered as dense, solid, and non-absorbent as ordinary painters’ canvas prepared for painting, and the clearness and depth of the photo graphic tone are increased to such a degree that the effect pro duced excels that of photographs on albumenized paper. The fabric may ultimately be painted with oil-colours and varnished, and treated in the same manner as ordinary oil-paintings Having thus fully described the said invention as communicated to me by my foreign correspondent, and the manner of perform ing the same, I wish it understood that I claim,—A woven fabric which, after having a positive photographic picture produced thereon, is coated on the one side with wax or equivalent fatty substance, and on the other side with varnish, substantially as and for the purpose specified. Specification Published during the Week. 3889. E. Edwards, for “ Photographic cameras.”—A communi cation from P. Rouaix. This invention relates to photographic cameras in which the operations of sensitizing and developing the glass plate upon which a picture is to be obtained are carried on in the camera itself, without the necessity for a separate dark chamber. The improved camera constructed according to this invention con sists of a front part and lens of any of the ordinary well-known kinds, and of a back part, of novel method of construction, in which the desired operations are effected. This part of the camera is provided at the back with a hinged door, which can be opened or closed as desired, and with a flat horizontal slide fitting below the top of the camera, and having a handle by which it can be drawn in or out as desired. Below this slide and near its front edge is arranged a groove provided with a spring, so that a separate ground glass for focussing can be readily inserted and held in it, the movable slide and glass being then pushed forward into their place against a stop inside the camera, and the picture being then accurately focussed upon the ground glass by means of a rack-and-pinion, or other equiva lent means in the ordinary way, and the lens is then closed. To sensitize the plate, the ground glass is removed, and a suitable plate, coated with iodized collodion in the open air, is inserted and fixed in its place. The slide is then pushed forward against the stop already described, the collodionized plate then hanging vertically over the centre of a suitable vessel containing silver sensitizing solution, which is fitted into an opening in the bottom of the camera. The back shutter is then closed, and the lens being already covered no light can reach the interior of the camera. The vessel containing the silver bath is then raised until the collcdionized plate is completely immersed in it, and it remains there until properly sensitized. The vessel is then lowered, and the sensitized plate occupying exactly the same position as that previously occupied by the ground glass, the lens is uncovered and the plate exposed for a sufficient time, when the lens is again covered. To develop the picture thus produced, the horizontal slide, together with the plate, is drawn back against a catch, in which position it is exactly above a second vessel fitted into a second opening in the bottom of the camera, and containing a suitable developing solution. This second vessel is then steadily raised until the plate is com pletely immersed in the solution, where it remains for a sufficient time, and the vessel being then lowered, the back shutter is opened, and the horizontal slide being drawn back, the plate carrying the developed picture is removed, and can be fixed or otherwise treated as desired. The vessels containing the baths may be made together or separate according to the size of the apparatus, and they are guided by grooves in the sides of the camera, and may be provided with movable water-tight covers, so that the removal of their con tents is unnecessary. Openings closed by hinged or other movable covers provided with suitable fastenings are made in the camera at the end of the openings in which the vessels are fitted, so that the latter can be removed to be cleaned or refilled when necessary.
