in a porous framework or receptacle. Its chief characteristics are absorptiveness and porosity, consequently air will penetrate to its interior as easily as water does, and the air-borne bacteria which assists in breaking up organic matter into inorganic substances will be enabled to perform their functions in the filter.

No. 22840.—14th May, 1907.—GEORGE SIDNEY WILLIDEN, of Dunedin, New Zealand. Slater. Improved water- and damp-proof concrete blocks.*

Claims.—(1.) In concrete building-blocks, the insertion of a sheet of non-absorbent material between the inner and outer faces of same to prevent the creeping of damp through said blocks, all substantially as shown in the drawing, and as described and explained. (2.) In reinforced building-blocks, the combination with same of a non-absorbent material placed so as to keep the damp from penetrating through the block, the reinforcement passing through the said non-absorbent material, substantially as set forth. (3.) In reinforced building-blocks of concrete, the combination with same of a non-absorbent material placed to keep the damp from penetrating the block, the reinforcement passing round the edge of the material, all substantially as set forth. (4.) In building-blocks, the combination of a horizontal and vertical damp-proof material, forming the usual damp-course, with the method of preventing the damp passing through the block, all substantially as set forth.

No. 22920.—30th May, 1907.—UNITED SHOE MACHINERY COMPANY, of Paterson, State of New Jersey, United States of America, a corporation duly organized 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 (the assignees of Emery Bayard, of Rochester, Monroe, New York, United States of America, Foreman). Improvements in or relating to method of and apparatus for use in making shoes.*

Claims.—(1.) In a machine employed for conforming uppers to lasts, and comprising the combination of a last, pivotally or otherwise supported, a device to engage the forward portion of an upper thereon, and means to effect relative movement of the said last and device, so arranging and operating these parts that as the distance between the said device and the maximum convexity of the heel is increased the tension exerted thereby through the forepart of the upper shall stretch towards the toe, for the purpose described, the whole of that portion of the heel end of the upper situated between the level of the edge of the last and the level of that maximum convexity. (2.) In a machine comprising the combination and carrying out the operation set forth in preceding claiming-clause No. 1, so arranging and operating the parts that the operation is effected without materially bending the upper over the toe part of the last, whereby the marginal parts of the upper will not be materially relieved from the lengthwise stress primarily set up in them. (3.) In mechanism employed to carry out the operation set forth in preceding claiming-clause No. 1 or Nos. 1 and 2, the provision of means to lock, while the shoe parts at the heel end of the shoe are adjusted and secured, the device or apparatus which exerted the tension aforesaid, whereby they are enabled to maintain that tension during the adjusting and securing. (4.) In the manufacture of shoes, a process which consists in (1) first employing the combination of a last, a device to engage the forward portion of an upper thereon, and means to effect relative movement of said last and device in such a manner that as the distance between the said device and the maximum convexity of the heel is increased the tension exerted thereby through the forepart of the upper shall stretch towards the toe, for the purpose described, the whole of that portion of the heel-end of the upper that is situated between the level of the edge of the last and the level of that maximum convexity; and subsequently employing, while the aforesaid tension is maintained, (2) the following steps, singly or in combination: (a) fastening the upper, with or without the stiffener or other contiguous parts, to the rear face of the last; (b) fastening the upper, with or without the stiffener or other contiguous parts, to the insole or to the last at the rear of the tread-face of the last; (c) by attaching the heel portion of the upper, with or without the stiffener or other contiguous parts, to the insole or to the last at the sides of the tread-face of the last. (5.) In an apparatus of the class described, the combination with means for sustaining a last in inverted position, of grippers arranged below the last and movable lengthwise of the last, and means to actuate the grippers for stressing the upper lengthwise of the last. (6.) In a machine employed for conforming uppers to lasts, and having its parts so arranged and operated as to carry out the operation referred to in preceding claiming-clause No. 1 or No. 2, the provision of a scale to indicate the extent to which the upper upon the last has been pulled lengthwise with relation to the last. (7.) In a machine employed for conforming uppers to lasts, and having its parts so arranged and operated as to carry out the operation referred to in preceding claiming-clause No. 1 or No. 2, the provision of a scale on each side of the last in the region of the tip seam, whereby the operator can determine the correct position to which to pull the said seam, with or without means for angularly adjusting the last. (8.) For carrying out the operation set forth in preceding claiming-clause No. 1 or No. 2, the apparatus substantially as described, and illustrated in the drawings.

Extract from Specification.—The apparatus comprises the following parts: 1. Members adapted to collect the effort of the sea-waves, working-surface, or the like. 2. Members adapted to actuate compressors, and to collect and distribute the compressed air. 3. Members adapted to transform the vertical movement into alternate rotary movement. 4. Members adapted to return the working-surface to its position of rest. 5. Members for rendering the working-surface elastic. 6. Supporting members for allowing the apparatus to be displaced in a longitudinal as well as in a vertical direction, so as to favour the flow and the rising of the waves upon the working-surface.
