Second, the pipe, D, aad valve, S, or their equiva leats, so constructed and arranged as to draw the water from the condenser by the raising of the diaphragm, thus causing the water pump to work an exhaust pump or its equivalent, to the condenser, at the same time that it does its ordinary work, as described. MANUFACTURING WIGS—By Charles Bourgard, of Ne f York City : I do not confine myself to the precise means of g'.ving motion to or adjusting the several parts essential to the operation of the machine; Iknow that it is possible to move and adjust them in other ways, to produce the same effect; and I do not claim the employment of the hooked or bearded needle, irrespective of the manner of its employment. But I claim (for the purpose of making the partings, or those parts of wigs and all articles of a similar nature, where the artificial scalp or skin isvi sible and the surrounding parts), the employmentof two or more adjustable slideirames forcarrying the silk or other material, into which the hair is to be inserted, in combination, as described, with a reciprocating hooked or barbed needle, either the said frame or needle having such a movement aa is necessary to insert the hairs at a proper distance apart. TANKING—By Henry Bretney, of Sprinfield, Ohio : I claim continuously towing the hides in separated layers, through the tanning liquor, in such manner that each hide, made fast only at one edge or end to the towing mechauiam, will be gently stretched and kept spread out by the resistance of the liquor, which is ciused freely to circulate in contact with both sides or surfaces of the hides, whereby every hide of quantity, however large, ia equally and constantly exposed to the action of the tanning liquor and the siretching action upon the hides adjusted, aa specified. SERVING MACHINES—By Freeman Palmer, of Con-naaut, Ohio : I claim the arrangement aud combination of parts, by which; the material to be sewed is carried around under the needle, in a way to secure any required length of stitch, consisting of the shaft aad the screw regulator, together with the lever and clamp, upon the feed wheel, substantially as described. ?WEARING APPAREL, &C.—By Samuel M, Perkins, of Springfield, Pa.: I claim the art or method as de scribed, of making seamless felt articles of use, and ?wearing apparel, by giving the batting of wool or fur the desired shape, and uniting its edges, where required, with silk or any other non-shrinkingequi-valent, or by such shrinking threads or fibre, aa will resume their original state, when dry, substantially as set forth.
