(2.) A connection as set forth in claim 1 wherein one or both of the jaws has projections such as serrations on its or their inner edge or edges. (3.) A connection as set forth in claim 1 having the arms provided with lateral lugs extending in opposite directions and perforated if required. (4.) A broom, brush, or other handle connection, substantially as described and illustrated in the drawings.

No. 23301.—15th August, 1907.—UNITED SHOE MACHINERY COMPANY, of Paterson, New Jersey, United States of America, a corporation duly organised under the laws of said State of New Jersey, carrying on business as Shoe Machinery Manufacturers, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America. (assignees of Benjamin Franklin Mayo, of Salem, Essex, Massachusetts aforesaid, Inventor, and Erastus Edwin Winkley, of Lynn, Essex, aforesaid, Mechanical Engineer). Improvements in or relating to sole-pressing machines.*

Claims.—(1.) In a sole-pressing or like machine, two forms connected to move laterally together (for example, the forms 2, 2), two forms co-operating respectively therewith, but fixed against lateral movement, and means for relatively actuating said forms to produce pressure and clearance, in combination with means for moving said first-mentioned forms alternately to a position of presentation between or in front of and between said co-operating forms. (2.) In a sole-pressing or like machine, a form-supporting table, two forms (for example the forms 2, 2) slidable over said table into position to co-operate respectively with two other forms which are fixed against lateral movement, means for relatively moving said forms into positions of clearance and pressure, and means for moving the forms supported upon the table to a position of presentation between or in front of and between said co-operating forms. (3.) In a sole-pressing or like machine characterised by the subject-matter claimed in preceding claiming clause No. 1, a construction of form-actuating mechanism comprising parallel non-co-axial mechanisms (for example, T-shaped arms, such as 10 and 11). (4.) A sole-pressing or like machine, having in combination co-operating sole-pressing forms, means for actuating said forms to exert a preliminary pressure upon a sole and thereafter a final pressure, and fluid-pressure mechanism acting automatically to vary by a locking or checking action the movement permitted to one of said forms to regulate the amount of such final pressure for soles of different thickness. (5.) A sole-pressing or like machine, having in combination co-operating sole-pressing forms, means for actuating said forms to exert a preliminary pressure upon a sole until the sole conforms to the shape of the forms, and thereafter a final pressure to mould the sole, and means (for example, 227) that are moved by the sole in relation to the space between the forms for regulating the amount of such final pressure. (6.) A sole-moulding machine, having in combination a yielding mounted rigid mould, a rigid mould co-operating therewith to mould a flat sole, means for moving said co-operating mould towards the yieldingly mounted mould to exert a preliminary pressure upon a sole until the sole conforms to the shape of the moulds and thereafter a final pressure to mould the sole, and means controlled by the sole when conformed to the shape of the moulds for limiting the movement of the yieldingly mounted mould. (7.) A sole-moulding machine, having in combination rigid male and female moulds adapted to mould a flat sole placed between them, means for supporting and actuating said moulds to exert a preliminary pressure upon a sole until the sole conforms to the shape of the moulds, and thereafter a final pressure to mould the sole, an adjustable stop for one of said moulds, and means controlled by the sole when conformed to the shape of the moulds for actuating said stop, said means including preferably a device (as 227) directly engaging the sole. (8.) A sole-pressing or like machine, having in combination male and female sole-moulding forms, a carrier removably secured to one of said forms, a sole gripping device mounted on said carrier and comprising a stationary jaw and a movable jaw arranged to engage opposite surfaces of a sole at the heel portion thereof, and means for adjusting the stationary jaw toward and from the movable jaw. (9.) A sole-pressing or like machine, having in combination upper and lower sole moulding forms, means for actuating said forms to produce pressure and clearance and for moving the lower form to a position of presentation out of alignment with the upper form, sole-gripping jaws mounted on the lower form, a stop arranged to actuate the jaws to release a sole when the lower form reaches its position of presentation, and means controlled by the operator and connected to the starting mechanism for the machine or not, as preferred, for actuating the stop to allow the jaws to grasp the sole while the lower form is in its position of presentation. (10.) A sole-pressing or like machine, having in combination male and female sole moulding forms and a gauge associated with one of said forms for engaging the side edge of a sole, said gauge being constructed and arranged to remain in any position to which it may be moved but being capable of movement in any direction.

No. 23380.—28th August, 1907.—RANDOLPH STUART SANDERSON, of Burnie, Tasmania, Australia, Accountant. An improved machine for calculating the weight of butter-fat in cream or milk.*

Claims.—(1.) In a machine of the class indicated, the general arrangement, construction, and combination of parts as described and operating in the manner and for the purposes set forth. (2.) In a machine of the class indicated, rollers revolvably mounted behind screens between which are openings through which numbers in rows along the rollers can be read, said numbers being so arranged as to be vertically between a system of constant percentages printed upon the screens, as set forth. (3.) The use in a machine of the class indicated of screens upon which constant percentages are printed, and another screen upon which are vertical columns and openings between the screens through which is disclosed only a limited portion of the numbered surfaces of rollers revolvably mounted immediately behind the screens in a compartment, as described and for the purposes set forth.

No. 23612.—25th February, 1908.—THOMAS MORRIS, of Dalry Road, Mornington, Dunedin, New Zealand, Medicine-manufacturer. An improved spring catch.*

Claims.—(1.) In spring catches for holding links or loads that are pressed between a bolt and block, in combination, a spring bolt with a block so formed that the desired article can be inserted by pressure between them, but cannot be withdrawn till the bolt is pressed back, all substantially as shown on the drawing, and as described and as explained. (2.) In combination, a spring bolt normally pressing against a block and bolt-head, with a loop or link capable of being pressed in between them, but not withdrawn till the bolt is moved back, all substantially as set forth, and as shown on the drawing.

No. 23842.—19th December, 1907.—EDWARD NEEDHAM WATERS, a member of the firm of Edward Waters and Sons, Patent Attorneys, of 414/418 Collins Street, Melbourne, Victoria, Australia (nominee of “Verein Chemischer Fabriken in Mannheim,” a corporation organized under the laws of Germany, carrying on business as Chemical-manufacturers at Wohlgelegen-Mannheim, in Germany—the assignees of Wilhelm Hasenbach, residing at Wohlgelegen-Mannheim, Germany, Chemist and Director of “Verein Chemischer Fabriken in Mannheim”). Improvements in the manufacture of reduction products of sodium-sulphate so as to obtain them in solid anhydrous pulverulent form.

Claims.—(1.) The manufacture of a mixture of sodium-sulphide and carbon which is infusible even at very high temperatures by heating, at a temperature of from 700° to 800° centigrade, a finely ground mixture of sodium-sulphate, and as much as twice the amount of carbon as would be required by the equation Na₂SO₄ + 4C = Na₂S + 4CO. (2.) The manufacture of sodium-carbonate and almost undiluted sulphuretted hydrogen by intimately mixing the solid pulverulent mixture of sodium-sulphide and carbon obtained in accordance with the preceding claiming clause
