Claims.—(1.) The improved system of applying pressure to liquids of less specific gravity than water, the same consisting in forcing water under pressure into the bottom end of a receptacle containing the liquid, as specified. (2.) In means for applying pressure to liquids of less specific gravity than water, a tank or receptacle adapted to hold the liquid, in combination with means for submitting water to pressure, and a connection between such means and the bottom end of the receptacle, as specified. (3.) In means for applying pressure to liquids of less specific gravity than water, in combination, a tank or receptacle adapted to hold the liquid, a steam-boiler, and a pipe connection leading from the lower end of the boiler into the lower end of the tank or receptacle, substantially as specified. (4.) In means for applying pressure to liquids of less specific gravity than water, in combination, a tank or receptacle adapted to hold the liquid, a steam-boiler, a water-tank containing water under air-compression, and connections leading from the boiler and from the water-tank into the bottom end of the liquid-receptacle, and a valve controlling each of such connections, substantially as specified.

(4.) In seed-sowers of the class described, a flange on the seed-box, claimed in claim (3), for retaining the drum in operative position, substantially as set forth. (5.) In seed-sowers of the class described, a spring for holding in operative position the seed-box claimed in claim (3), substantially as set forth. (6.) In seed-sowers of the class described, in combination with the seed-box, claimed in claim (3), of a hinged flap adapted to close one or other of passages in the said seed-box, substantially as set forth. (7.) In seed-sowers of the class described, a seed-box fitting the bottom of the hopper and forming a passage for seeds to one part of the drum, and forming with the side of the hopper a second passage for directing the seeds to another part of the drum, substantially as set forth.

No. 22764.—2nd 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 at 205 Lincoln Street, Boston, Massachusetts, United States of America (the assignees of Benjamin Franklin Mayo, of Salem, Essex, Massachusetts aforesaid, Inventor). Improvements in lock-stitch wax-thread shoe-sewing machines.*

———

Claims.—(1.) A lock-stitch wax-thread shoe-sewing machine having, in combination, stitch-forming devices, and means for actuating said devices to manipulate the thread in forming a stitch, and simultaneously to exert a pull on the thread to tighten or set a preceding stitch. (2.) A lock-stitch wax-thread shoe-sewing machine having, in combination, stitch-forming devices, and means for actuating said devices to manipulate the thread in forming a stitch, and to exert during a substantial portion of the time occupied in such manipulation a pull on the thread to tighten or set a preceding stitch. (3.) A lock-stitch wax-thread shoe-sewing machine having, in combination, stitch-forming devices including a stitch-setting device, and means for actuating the stitch-setting device to engage the needle-thread close to the work, and to exert a pull on that portion only of the thread which leads from said device to the work. (4.) A lock-stitch wax-thread shoe-sewing machine having, in combination, stitch-forming devices including a hooked needle, a shuttle, a take-up and a stitch-setting device, means for actuating the take-up to draw thread from the loop of needle-thread after the passage of the shuttle therethrough, and means for actuating the stitch-setting device to grasp the needle-thread and exert a pull on the thread to set the stitch. (5.) The improved stitch-setting apparatus for a lock-stitch wax-thread sewing-machine, substantially as described with reference to the drawings.

(2.) In a wax-thread or other sewing-machine, the combination with a needle-lubricating element (such, for example, as 10) movable into and out of engagement with the needle, and carried on a lever (for example 11), of means, such as the spring 15 and stop 17, to hold the lever yieldingly for the purpose described. (3.) The needle-lubricating device and reservoir arranged and operating substantially as described in the drawings.
