No. 12680.—13th June, 1900.—EDWARD WATERS, Jun., a member of the firm of Edward Waters and Son, of 131, William Street, Melbourne, Victoria, Patent Agent (nominee of Raymond Combret, of 18, Rue Mogador, Paris, France). An improved process for tanning and treating hides and skins.

Claims.—(1.) Process for tanning and treating hides and skins which consists in treating the said hides and skins in solutions or liquors containing small quantities of formic aldehyde in combination with systematically determined quantities of free acids, in particular acetic acid, such treatment being effected either at atmospheric temperature or, preferably, at a moderate temperature in closed vessels, having motion imparted thereto, substantially as described. (2.) In the process for tanning and treating hides and skins referred to in the first claim, the employment for the combined formic-aldehyde and free-acid solutions of from 1/100 to 1/800 parts of formic aldehyde and from 1/250 to 1/1000 parts of free acid, substantially as described. (3.) In combination with the process referred to in the first and second claims, the supplemental application of the known liquors, extracts, tanning-materials, or dye-stuffs, for imparting to the hides the desired tints, or for increasing their weight and rendering them similar to leather of existing manufacture, substantially as described. (4.) The application of the process referred to in the first and second claims to all kinds of leather-manufacture, such as white leathers, chamois-leathers, hides or skins having the furs or feathers left thereon, which hides or skins may be subsequently rendered waterproof, or otherwise treated for rendering them applicable to various industrial applications, substantially as described.

(2.) In a fodder-holder, the combination with lengths of chain provided with hooks, of an assembling-bar having eyes and attached to the ends of the chain, and a spacing bar or bars spreading the chains apart, substantially as set forth.

No. 12696.—19th July, 1899.—JOSEPH YARDLEY JOHNSTON, of 22, Bride Lane, London, England, Manufacturer of Steel Die and Plate Presses. Improvements in presses for printing or embossing.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Extract.—This invention has reference to the impression-mechanism of printing, embossing, or printing-and-embossing presses, in which the downward stroke of a plunger causes the engraved or other printing- or embossing-surface (hereinafter called a “die”) to strike the material to be printed or embossed, objects being to provide more effectively than heretofore usual for preventing the die, after it has struck the material to be printed or embossed and has once left the same, returning thereto until the proper time for its next stroke, for enabling the plunger to rebound quickly and the die to leave the material immediately after the impression has been struck, and for obviating shock and vibration. The drawings illustrate a convenient arrangement of impression-mechanism according to this invention, which I will now describe, premising that, as here described, my improved apparatus is applied in a press which (for convenience of description) I will assume is to be used for printing, and which is so arranged that an arm adapted to revolve in a horizontal plane, and carrying the die at its end, first passes over apparatus which charges the die with ink, then over a wiping-
apparatus which removes all superfluous ink, leaving only the female part of the die charged, and is then brought to rest and locked in register over a counter, force, male-plate, or other part between which and the die the impression is to take place, the impression being then given by a blow of the die caused by the release and descent of the plunger from the raised position to which it had been carried, and in which it had been locked during the preceding cycle of operations.

[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing extract from the descriptive part of the specification is inserted instead.]

No. 12697.—18th July, 1899.—JOSEPH YARDLEY JOHNSTON, of 22, Bride Lane, London, England, Manufacturer of Steel Die and Plate Presses. Improvements in inking-apparatus for printing-presses.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claim.—(1.) An inking-apparatus for printing or printing-and-embossing presses, comprising a table, a removable ink-reservoir freely supported by said table, and means for insuring the correct relative positions of said table and reservoir, as set forth. (2.) An inking-apparatus for printing or printing-and-embossing presses, comprising a table formed with sockets, and a removable ink-reservoir having projections adapted to fit said sockets, as set forth. (3.) An inking-apparatus for printing or printing-and-embossing presses, comprising a spring-supported table, a removable ink-reservoir freely supported by said table, and means for insuring the correct relative positions of said table and reservoir, as set forth. (4.)
