No. 18751.—16th November, 1904.—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, and having a place of business at 205, Lincoln Street, Boston, Massachusetts, United States of America (assignees of Benjamin Franklin Mayo, of Salem, Massachusetts aforesaid, Inventor). Improvements in or relating to machines for trimming and concaving the breasts of heels.*

Extract from Specification.—The machine, specifically described by way of exemplification only, contains a shaft provided in this instance of the present invention with a primary and a secondary rotary cutter, one following the other in operation in concaving the breast of the heel. The primary cutter is provided with blades shaped to cut in the breast a concave extending substantially from the breast-edge of the top lift to the highest point of the face of the shank without injuring the shank, and the secondary cutter acts to trim the breast from substantially the level of the highest point of the shank to the point where the breast meets the sole-edge. While the primary cutter is doing its work the shoe is held on a jack under the control of the operator, said jack having provision for supporting the shoe with the face of the top lift and the breast of the heel in acute angular position with relation to the longitudinal axis of the cutter-carrying shaft, thus enabling the heel-breast to be properly presented for the operation of the cutter in concaving the breast of the heel. Said jack is movable to present the shoe to the cutter, its movement being controlled by suitable guides. The jack carries a support for the tread of the heel, and on this support is a device for positioning the breast-edge of the top lift. To enable the concave in the breast to be varied in shape and depth without changing the cutter the jack is so mounted that it may be turned about a centre located substantially in the line of travel of the edge of the blades of the cutter, and in the line of the breast-edge of the top lift when a shoe is in position on the jack, so that when the jack is rotated the position of the breast-edge of the top lift relatively to the cutter will not be changed. Thus by a slight rotation of said jack the depth of the cut into the breast of the heel may be varied without varying the cut at the top lift. The device shown for positioning the breast-edge of the top lift consists of a lip on the support for the tread-face of the heel. The acting-face of this lip stands always in line with the axis of rotation of the jack, and also immediately adjacent to the path of the blades of the primary cutter, so that when the jack is rotated to vary the depth of the cut into the breast the position of the extreme edge of the acting-face of the lip with relation to the primary cutter is unchanged. The secondary cutter has combined with it a guard to engage the shank while that cutter is operating, the purpose of said guard being to obviate cutting into and marring the shank of the sole, the guard also determining the depth of the cut to be made by the secondary cutter.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19181.—8th March, 1905.—ROOKWOOD COMFORT BISHOP, of Cambridge Terrace, Christchurch, New Zealand, Secretary of the Christchurch Gas, Coal, and Coke Company, Limited, whose registered office is at 158–160, Worcester Street, Christchurch aforesaid. Improvements in and relating to boilers for gas-ranges.*

Claims.—(1.) Apparatus for the purpose indicated, comprising, in combination, a boiler having recesses formed in the top of the boiler, burners placed within the recesses,

there being openings through the boiler for admission of air to the recesses, channels formed in the top of the boiler to receive the necks of burners and leading from the recesses and sloping downwardly to the side of the boiler, and a cock for drawing off water, substantially as set forth. (2.) Apparatus for the purpose indicated, comprising, in combination with a gas cooking-range, a boiler adapted to rest upon the top of the oven, recesses formed in the top of the boiler, burners placed within the recesses, there being openings through the boiler for admission of air to the recesses, channels formed in the top of the boiler leading from the recesses and sloping downwardly to the side of the boiler, a cock for drawing off water, an extension to the top of the range, brackets supporting the extension, a water-cistern resting upon the extension, flow and return pipes connecting the cistern and boiler, substantially as set forth. (3.) The combination and arrangement of parts comprising the improvements in and relating to gas-heated boilers substantially as set forth.

No. 19377.—20th April, 1905.—HUGH MCFADYEN DOUGLAS, 47, Willis Street, Wellington, New Zealand, Bookbinder, Paper-ruler, and Account-book Manufacturer. A loose-leaf account-book transfer-binder.*

Claims.—(1.) Apparatus for filing the leaves of loose-leaf account-books, comprising a frame, a right- and left-hand threaded screw having a square end and journaled within the frame, nuts fitting the screw and having extensions, a plate, pillars secured to the plate at a distance apart corresponding to the distance apart of the pillars of a loose-leaf binder, there being holes in the frame adapted to receive the pillars, substantially as set forth. (2.) Apparatus for the purpose indicated, characterized by comprising among its parts a frame in which a right- and left-hand threaded screw is journaled, a plate provided with pillars adapted to pass into holes in the frame, nuts on the screw having extensions adapted to engage the pillars, substantially as set forth. (3.) The combination and arrangement of parts comprising the loose-leaf account-book transfer-binder, substantially as and for the purposes set forth, and illustrated on the drawing.

No. 19425.—4th May, 1905.—NATHANIEL LOMBARD, of 81, Thomas Street, Worcester, Massachusetts, United States of America, Mechanical Engineer. Improvements in governors.

Extract from Specification.—The operation of this improved governor is as follows: With the parts in the relation illustrated power is applied to the pulley 28 to drive the centrifugal mechanism left-handedly at such a rate that normally for the desired speed of rotation of the machine the weights of the centrifugal mechanism contained within said pulley will be retained substantially at the centre of their range of movement, and the various screws, racks, and the roller 99 will also be at the centre of their path. This condition continues until there is a change in the speed of the motor, as, for example, an increase. This results in causing the weights forming part of the centrifugal mechanism to move outwardly under the increased centrifugal force generated, and the racks 87 secured thereto will be moved thereby, and operating through the segment 86 the slidable member 85 will be permitted to move in the direction indicated by the arrow on Fig. 5. This movement of the slidable member will operate upon the pivoted lever 77 to move the lower end toward the front of the machine while the upper end is moved in the opposite direction, thereby causing through the power-cylinder piston 45 a movement of the operating-rod 32 in the direction indicated by the arrow on Fig. 4. This movement of the operating-rod 32 in a direction toward the left of Fig. 4 causes the clutch-member 21 at the right of said figure to be set so that the actuating-shaft 13 and the operating-member 32 will be rotated about their axes in unison with the clutch-member 21 in the direction indicated by the arrow, Fig. 6, or toward the front of the machine. To counteract the effect of the power-cylinder upon the clutch, to permit the return of the valve to its normal position and a consequent checking of the piston to stop the movement of the gate, the relative positions of the lever 37 and the operating-rod 32 are automatically changed in the following manner: As soon as the actuating-shaft begins its rotation through the connection made by the clutch 21 it also rotates the operating-rod 32. This causes the threaded end of said rod to move in the lever to the right, and this being in the opposite direction to the travel of the block 42 tends to release the clutch. As long as the piston continues its movement the rate of travel of the upper end of the lever will offset that caused by the operation of the
