(4.) A caulking-machine having union bars, on which bars are carried or arranged the caulking-tools in such a manner that they impinge and travel right on to the face-edge of the lead joint, and being provided with tension-spring mechanism as denoted by the parts marked 33 to 35, substantially as and for the purposes specified and set forth, and as illustrated in the drawings. (5.) The peculiar construction, combination, and arrangement of a caulking-machine consisting of the operative driving-gearing and circumferential geared rims for carrying the caulking-tools, and the means provided whereby such rims and their attached parts are drawn together in an inward direction, so as to obtain a caulking or compression action, and further the means provided whereby such rims and their parts travel or rotate around the pipe in a circumferential or peripheral manner, substantially as and for the purposes specified and set forth, and as illustrated in the drawings. (6.) A caulking-machine having the parts as above claimed, illustrated, and set forth, with the addition of the parts denoted by the parts 36 to 40, in order that it is usable for cutting pipes and such-like purposes, substantially as explained and set forth, and more particularly shown in Figs. 3 and 4 of the drawings.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) An automatic railway-coupling, consisting in the combination with a draw-link of substantially U-shape (pivoted and normally supported as described), in position to engage with the draw-hook on an adjacent vehicle, of a draw-hook pivoted and weighted as described, and presenting an inclined nose to the draw-link to be engaged therewith, and of a sliding locking-bolt engaging with the draw-hook so as to normally prevent it yielding under the hauling-strain, substantially as described. (2.) The combination with an automatic coupling comprising a pivoted draw-hook and a pivoted draw-link constructed and adapted to enter into engagement substantially as described, and provided with a locking-bolt adapted to engage with and lock the draw-hook, of retaining and releasing mechanism for said bolt, consisting of a rock-shaft having a crank connected with the locking-bolt, and of weighted-tumbler mechanism in engagement with the cross-shaft, so as to operate substantially as described. (3.) A releasing-gear for uncoupling railway-couplings, consisting in the combination of a pivoted draw-hook, a locking-bolt adapted to engage with the rear end of the draw-hook, and of retaining and releasing mechanism for said bolt, consisting of a rock-shaft having a crank connected with the bolt, and of weighted-tumbler mechanism connected with the rock-shaft, for operation substantially as described.

No. 12665.—6th June, 1900.—ANDREW MCMILLEN ERNSBERGER, of 31, Cortlandt Street, New York, United States of America, Manufacturer; and ARTEMAS WARD, of 1, Union Square, New York aforesaid, Publisher. Amalgamating-machine.

Claims.—(1.) In an amalgamating-machine a framework adapted to carry horizontal revolving drums at a distance apart and above the same, a vertical disintegrating-cylinder, an amalgamated belt upon the drums, and means for its driving, revolving and stationary disintegrating-means within the vertical cylinder, means to operate the same from the means to run the amalgamated belt, means to introduce material into the disintegrating-cylinder at opposite sides, by feeding-mechanism driven from the drum-shaft, and in uniform and in desired quantities, means to deliver the material thereafter to the amalgamated belt across its width, means to press the material to the amalgamated belt as it passes from drum to drum, and distributors at each side of the pressing-means, substantially as described and set forth. (2.) In an amalgamating-machine, a pair of drums, one in fixed position and one in movable position, a belt upon the drums, a cylinder above the belt, a hopper above the cylinder, feeding-means within the hopper to deliver material to be operated upon into the cylinder by mechanism worked from the belt-operating mechanism, means within the cylinder to rapidly move and disintegrate the material, means to distribute the material evenly to the belt, multiple rolling-means to press the material to the belt, means to distribute the before- and after-pressure to the belt, and means from the drum-shaft to drive the mechanism to cleanse the belt, substantially as described. (3.) In an amalgamating-machine, a framework, drums thereby supported, one in fixed and one in movable position, and means for its moving, multiple rollers upon a belt run upon the drums, brackets upon the framework, and distributors composed of flexible material secured to brackets so distributed as to place the distributors at each side of the rollers, in continuous stretch from bracket to bracket, reaching across the belt, and adapted to continuously touch the belt upon its upper surface with their lower edge, substantially as described. (4.) In an amalgamating-machine, a framework, a fixed and a movable drum thereon, a belt upon the drums, pressure-rollers above and carrier-rollers below the belt, between the drums, and pressing upon opposite sides of the belt at the same time, the upper ones being adapted to move to or away from the belt, and means to cause them to press with greater or less degree upon the belt, distributors at either side of the upper rollers, secured to the framework, and adapted to touch the belt but to yield under pressure, and a flexible dam secured to each outer edge of the belt, substantially as described. (5.) In an amalgamating-machine, a framework, drums carried thereby for revolving, one in a fixed and one in a shifting position, a belt upon the drums, positive means for revolving the drums in unison, a water-receptacle adjacent to the fixed drum, a shaft journaled upon the framework above the receptacle, a revolving brush yieldingly supported, partially immersed in the water, means upon the shaft to support the brush in normal position clear of the belt aforesaid, means upon the arms to elevate the brush to the belt, means to hold it in such elevated position or remove it from contact with the belt, and means from the drum-driving mechanism to revolve the brush, substantially as described. (6.) In an amalgamating-machine, a framework therefor, carrying drums and a belt, a water-tank and a brush therein, means to press the brush to the belt or remove it from the belt, and a wringer-roller, suspended from the framework in manner to cause it to normally fall away from the belt by its own gravity, and means to move the wringer to and press against the belt or away from contact with the belt, as and for the purposes set forth.
