No. 19214.—18th March, 1905.—WILLIAM ERNEST HUGHES, of Queen's Chambers, Wellington, New Zealand, Patent Agent (nominee of William John Yesell, of 1867, Seventh Avenue, New York, United States of America, Artist). Improvements in printing-surfaces and their production.*

Extract from Specification.—Briefly stated, my improvement in the art of producing printable replicas direct from the original type, electrotype, half-tone, and engraved or other relief or intaglio forms, eliminates the necessity for an engraved, etched, cast, or otherwise prepared metal co-operating die, and is preferably carried into effect by forcing together the type, plate, or other original and the blank of sheet metal or other suitable material by a swaging or kneading pressure, as by rolls or in a press, preferably with a blanket of pulpy, fibrous, or other soft but resistant material, by which the material of the blank is worked intimately against every projection of the original, a harder blanket stratum being subsequently forced against the blank and form, producing a sharp plate with all the details of the original and of even thickness throughout; and, in fact, such a plate will present on its relief side a smooth, uniformly plane surface replication of the type or other printing-surface on which it was formed, and superior to said original in printing-qualities.

No. 19260.—28th March, 1905.—WILLIAM WALKER, of Hayward's, Wellington, New Zealand, Farmer. Improved teat-opener for cows and other animals.*

Claims.—(1.) An instrument for the purpose indicated, consisting of a cutter mounted in a handle and having three cutting-edges, substantially as specified and illustrated. (2.) An instrument for the purpose indicated, consisting of the parts constructed, combined, and operating substantially as specified and as illustrated in the drawing.

No. 19273.—30th March, 1905.—UNITED SHOE MACHINERY COMPANY, of Paterson, in the State of New Jersey, United States of America (a corporation duly organized under the laws of said State of New Jersey, and having a place of business at 205, Lincoln Street, Boston, Massachusetts, United States of America), assignees of Erastus Edwin Winkley, of Lynn, Essex, Massachusetts aforesaid, Mechanical Engineer. Improvements in or relating to presser-foot mechanism for sewing-machines.*

Extract from Specification.—The present invention contemplates the provision of a presser-foot-actuating mechanism constructed and arranged to hold the presser-foot yieldingly against the work, then to yieldingly move the presser-foot toward the work-support to clamp the layers of material together, and finally to exert a positive predetermined uniform action on the presser-foot to lock the presser-foot in clamping position. Preferably the presser-foot-actuating mechanism is constructed and arranged to positively move the presser-foot a predetermined uniform distance after it has been yieldingly pressed against the work in order to bring it into its final clamping position. In certain types of sewing-machine a presser-foot has been employed in combination with an actuating lever therefor, connections between said

lever and presser-foot, and means for actuating said connections to release the presser-foot and allow it to accommodate itself to stock of varying thickness; but we believe that we are the first to employ means for effecting independently of motion of the said lever a preliminary adjustment of said connections to engage the presser-foot and take up lost motion between the foot and its actuating lever. The presser-foot is provided also with means by which the operator may unlock and raise it for the purpose of inserting the work in place. In one form of construction separate levers or handles are employed respectively for unlocking and for raising the presser-foot, but in the preferred form of the invention a single hand-operated part is adapted in one movement, first to unlock and then to raise the presser-foot.

No. 19334.—12th April, 1905.—PERCY LEONARD WESTON, of University of Sydney, Darlington, New South Wales, Australia, Electrical Engineer. An improved bevel-gear milling-machine.*

[NOTE.—The title in this case has been altered. See list of provisional specifications, Gazette No. 46 of the 18th May, 1905.]

Extract from Specification.—The essential features of the invention are : The use of an elongated rotary tool or cutter and means for so guiding it with its axis in the direction of the intertooth grooves that it describes an involute path. This guiding motion is geometrically that of a plane disc rolling on a fixed cone, the latter of which bears a definite relation to the pitch-cone of the bevel-gear to be cut.

No. 19567.—7th June, 1905.—JOHN ROBERT HARRISON, of 47, Albert Street, Ballarat, Victoria, Australia, Ironfounder. An improved amalgamator and concentrator for ores and tailings.*

Extract from Specification.—This invention relates to an improved amalgamator and concentrator for ores and tailings. It consists of a table or annular pan whose surface is of a tapering volute form in plan, provided with an internal gutter or race to receive and carry off the gangue. The said table-surface is slightly inclined downwards transversely from its inner edge to its outer rim or periphery, and also it inclines downwards circumferentially from its feed-end to its discharge-end; further, the table is suspended from overhead supports, and has a gyratory or eccentric shaking motion imparted to it by a horizontal eccentric which works in a boss at the centre of pan-arms; also for some classes of ore, and especially rich ore, two or more pans may be supported one above the other.

No. 19816.—1st August, 1905.—DOMINIC KRMPOVIC, of 731, Brunswick Street, Fitzroy, near Melbourne, Victoria, Australia, Shoemaker. An improved pea-shelling machine.*

Claims.—(1.) In a pod-shelling machine, the combination, with a casing, of a series of inclined narrow slideways, rollers of ribbed rubber, or having suitable surfaces located so as when rotated to receive pods from the slideways, draw them between the rollers, split them, discharge them empty, and crowd their contents back; and means to rotate the rollers, substantially as indicated. (2.) In a pod-shelling machine, the combination, with a casing, of a series of inclined narrow slideways, means to vibrate the said slideways, rollers of ribbed rubber, or having suitable surfaces located so as when rotated to receive pods from the slideways, draw them between the rollers, split them, discharge them empty, and crowd their contents back; and means to rotate the rollers, substantially as indicated. (3.) In a pod-shelling machine, the combination, with a casing, of a series of slideways, and rollers adapted when turned to draw pods therefrom, empty the pods, and remove the empty shells as described. (4.) In a pod-shelling machine, the combination, with a casing, of a series of slideways, and ribbed rubber or like rollers adapted to draw pods therefrom, empty the pods, and remove the empty shells, one roller being located higher than and forward of the other. (5.) In a pod-shelling machine, the combination, with a casing, of a series of slideways, a spring connecting the casing and the series of slideways, a roller to which the slideways lead, and a lever adapted to be vibrated to shake the slideways as described.
