(4.) In a vehicle-wheel having segmental sections fitted together tangentially to the bore of the wheel, such as specified in claim 1, so shaping the outer ends of the said sections as to provide a zigzag or undulated circumference forming recesses, wedge-like pieces fitted into the latter, and vulcanised rubber or other resilient material inserted between the said zigzag or undulated circumference and the said wedge-shaped pieces, all substantially as and for the purpose set forth. (5.) In a vehicle-wheel having segmental sections fitted together tangentially to the bore of the wheel and shaped to provide a zigzag or undulated circumference forming recesses, wedge like pieces fitted into the latter, such as specified in claim 4, a boss in the bore of the wheel having flanges, rings at each side of the wheel, and rivets passing through the said segmental sections and wedge-shaped pieces, flanges, and rings respectively, all substantially as and for the purpose set forth. (6.) In a spoke vehicle-wheel such as specified in claim 1, spokes having wedge-like inner ends fitted against each other tangentially to the hub or boss of the wheel, all substantially as and for the purpose set forth. (7.) In a spoke vehicle-wheel, such as specified in claim 1, a circularly divided felloe with adjoining end relatively displaced, and spokes with tenons passing through the inner-felloe part only, and bearing against the continuity of the outer-felloe part, all combined substantially as and for the purpose set forth.

No. 17990.—1st June, 1904.—LOUIS PEARCE, of Manning’s Buildings, South Terrace, Fremantle, Western Australia, Architect. Rapid-release sash-fastener.

Claims.—(1.) A sash-fastener constituted by a pivoted or drop pawl formed with a retention or heel piece and with an operative button-piece, substantially as set forth, and as illustrated in the drawings. (2.) A sash-fastener provided with a ratchet of a curved or serrated form by which the above-claimed drop-pawl and window is held as desired, substantially as set forth, and illustrated in the drawings. (3.) A sash-fastener having a casing or container frame formed with a cup and with a trunnion on which the drop-pawl hangs and works, substantially as set forth, and as illustrated in the drawings. (4.) A vertical sash-fastener consisting of a drop-pawl formed with a heel and button-piece, and held and pivoted in a casing secured to the window, said pawl being in operative engagement and combination with a ratchet whereby the window is retained in any position, substantially as set forth, and as illustrated in the drawings.

No. 17992.—1st June, 1904.—EMIL BERGMANN, of Suhl in Thuringen, Germany, Engineer. An improved friction-gearing for motor-cars and similar vehicles.

Claims.—(1.) A friction-gearing for motor-cars, arranged in such a way that the impelling force of the driving-wheels acts directly on the axle and thus varies the adherent pressure between the friction-discs, this gearing being characterized by the back axle being movable in the direction of the axis of the car, and thus tending to displace by suitable means the axle of the driven disc in the direction of the driving disc, with the object of accommodating the adherent pressure of the friction-gearing at every instant to the force necessary to propel the vehicle, substantially as set forth. (2.) A device for releasing the friction-gearing, allowing the lever or pedal which produces the separation of the driven disc from the driving disc to operate at the same time the check which prevents the spontaneous displacement of the driven disc, this releasing device being characterized by a spindle set in the frame parallel to the axle of the driven disc, and capable of being rotated by a pedal which also carries the levers which serve to draw back the axle of the driven disc, the check-lever which when at rest prevents the rotation of the ratchet wheel connected
by suitable means with the driven friction disc in such a way that an axial displacement of the latter is only possible when the ratchet-wheel is revolved at the same time, substantially as set forth and as shown. (3.) Friction-gearing according to claims 1 and 2, in which the pedal brings about, in addition to the control of the devices mentioned in claim 2, the tightening of the brake, substantially as set forth above and illustrated in the drawings. (4.) A form of the friction wheel or disc claimed in claim 1 having one or more drums adapted to be rotated so as to wind or tighten up the leather or other friction-band on the periphery of said disc, said drum being provided with a ratchet-wheel with which a spring-actuated pawl is normally in engagement, all for the purposes and substantially as described and illustrated.

No. 17997.—1st June, 1904.—DAVID CARLAW, Sen., DAVID CARLAW, Jun., ALEXANDER LYLE CARLAW, and JAMES WHITE CARLAW, all of 11, Finnieston Street, Glasgow, Scotland, Engineers. Improvements in printing and numbering machines.

Claims.—(1.) A hollow numbering or numbering and printing cylinder having the numbering-wheels arranged within the cylinder and adapted to revolve in a plane at right angles to the plane of revolution of the cylinder, substantially as described. (2.) A hollow numbering or numbering and printing cylinder having the numbering-wheels arranged within the cylinder and adapted to revolve in a plane at right angles to the plane of revolution of the cylinder, said cylinder having the body and ends made in one piece, and provided with a cross-bridge and side pieces, which latter are removably fastened to the body and bridge in order that the numbering-wheels can readily be removed or changed whenever desired, substantially as described. (3.) In combination, a hollow rotary numbering or numbering and printing cylinder, numbering-wheels arranged within the cylinder and adapted to revolve in a plane at right angles to the plane of revolution of the cylinder, and means for automatically revolving the wheels, substantially as described. (4.) The mechanism for automatically revolving the numbering-wheels comprising a cam, a rocking-bar, a cam thereon, a slide actuated by the cam, a swinging arm operated by said slide, and pawl-and-ratchet gear, all substantially as described with reference to the drawings. (5.) In combination, a hollow numbering or numbering and printing cylinder made in parts removably fastened together, numbering-wheels within the cylinder and adapted to revolve in a plane at right angles to the plane of revolution of the cylinder, a case for the numbering-wheels carried by a bar, means for adjusting the case upon the bar, and means for automatically revolving the numbering-wheels, all substantially as described with reference to the drawings. (6.) The automatically acting sheet or leaf folding mechanism comprising, in combination, a folding-knife having cuts or recesses for the travelling tapes, a cam for reciprocating the knife, mechanism for operating the cam, and a double arrangement of tapes running on rollers for receiving, pressing, and delivering the folded paper, substantially as described with reference to the drawings. (7.) The revolving hopper or collecting-wheel for collecting the checks, sheets, and the like in sequential order and in certain numbers, constructed and operated substantially as described with reference to the drawings. (8.) In combination, rotary cylinders for numbering and [or] printing paper divided or to be divided into sheets, numbering-wheels arranged within the cylinders and adapted to revolve in a plane at right angles to the plane of revolution of the cylinders, mechanism for automatically revolving the numbering-wheels so that they may number the sheets of paper in proper sequential order, mechanism for automatically folding the sheets of paper, and mechanism for collecting the folded sheets in bunches or piles ready to be bound up into books, substantially as described with reference to the drawings.
