No. 12791.—17th July, 1900.—UNITED SHOE-MACHINERY COMPANY, of Paterson, New Jersey, United States of America, a corporation organized under the laws of New Jersey, and having its principal place of business at 111, Lincoln Street, Boston, Massachusetts, United States of America (assignees of Sherman William Ladd, of Beverley, Massachusetts aforesaid, Inventor). Improvement in lasting-machines.

Extract from Specification.—In machines of this class the boot or shoe is prepared for the lasting operations by suitably arranging the last, upper, lining, &c., and overdrawing the upper at the toe and along the ball at each side of the last, and there fastening it to the inner sole by a tack or similar fastening-device in each of said places. A single pair of pincers is employed, to which the boot or shoe is presented and turned about by the workman, the lasting-operation as a whole being carried out progressively by repeated operations of the machine applied to different parts of the upper at different times. Tack supplying and driving mechanisms are employed, whereby the part of the upper acted upon by the machine at one time is secured in place to the inner sole preliminary to the next operation of the machine. Mechanism is employed whereby wire or a similarly continuous material is placed progressively in binding relation with the successively lasted parts of the upper, particularly about the toe portion of the shoe, said wire being then secured in place, and thereafter serving in place of said tacks for holding said manipulated parts of said upper against displacement. This invention, in part, relates to means for suspending the insertion of said tacks during the time of said wire-placing operations of said machine, and, further in part, to means for variably controlling the tension of said wire, and to means for shifting the wire-placing mechanism into and out of operative positions, and to mechanism for cutting said wire.
[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. 12792.—16th July, 1900.—WILLIAM BURGELAND JOHNSON, of 51, Egerton Street, Liverpool, England, Engineer. Improvements in ventilators.

Claims.—(1.) In a ventilator, the combination with an air-passage of stationary vanes near one end thereof, and a movable vane arranged between the stationary vanes, and provided with an extension-piece, and adapted to close the openings between or alongside the vanes, substantially as described. (2.) In a ventilator, the combination with an air-passage of stationary vanes near one end thereof, a movable vane arranged between the stationary vanes, and provided with an extension-piece, side pieces attached to the movable vane, and pivots on which the movable vane is hung by means of the side pieces, substantially as described. (3.) In a ventilator, the combination with an air-passage of stationary vanes near one end thereof, a movable vane arranged between the stationary vanes, and a bent extension-piece connected with the movable vane, said movable vane and extension-piece being adapted to close the openings between and alongside the vanes, substantially as described.

No. 12793.—16th July, 1900.—CARL JOHAN KIELBERG, of Hillerod, Denmark, Polytechnic Student. Method and apparatus for making all kinds of articles with cylindrical cavities from cement mortar, moulding-sand, clay, or other substance of similar consistence.

Claims.—(1.) Method for making all kinds of articles with cylindrical cavities from cement mortar, moulding-sand, clay, or other substances of similar consistence, characterized by the moulding being done by a cylindrical movable drum or similar body, with one or more principally spiral projections, being screwed up through the substance placed in the mould, and compressing the said substance during the moulding. (2.) Apparatus for the carrying-out of the method described in claim 1, characterized by a drum rotating within the mould, and fitted with spiral projections, which drum forms the core of the mould, and which is screwed up through the moulding-substance placed in the mould, thereby compressing the former and moulding the article. (3.) Apparatus for the carrying-out of the method described in claim 1, characterized by a cylindrical body rotating in the mould, and fitted with spiral projections, being screwed up through the moulding-substance in the mould, fitted with a fixed core, thereby compressing the substance during the moulding. (4.) In the apparatus described in claim 3, the arrangement that the core during the moulding rotates round a vertical axle without being raised. (5.) In the apparatus described in claims 2–4, the arrangement of the spiral projections running horizontally in the lower portion for the purpose of smoothing, at the finishing of the moulding of pipes, the end surfaces of the latter.
