The following inventions have been patented this weei, as will be found by referring to our List of Claims: IMPKOVED PKINTING PRESSG W Davis, of Seneca Falls, N Y, has invented an improved printing press, the improvement in which consists in the employment of a swinging platen, adjustable spring frisket, inking device, and a reciprocating bed, arranged so that the several parts are, by the most simple means, operated conjointly by the movement of a single lever, The improvement is intended chiefly for hand presses GALVANIC BATTERIESBy the application of covers of nonconducting material through which the binding screws pass, and protecting the binding screws by means of washers from the action of the acids, the inventor, G Doyle, of Ottawa, 111, has produced a battery which is free from the common objection of local action between the jars, and the corrosion of the binding screws is prevented MACHINE FOR SHELLING PEASThis invention consists in the employment of rollers in connection with a series of endless cords, arranged and used with or without a vibrating hopper, so that the peas may be shelled and separated from their pods with the greatest facility W J Stevenson, of New York, is the inventor An engraving of this invention will soon appear in our columns BRICK MACHINEThis is an improved machine for molding bricks, and is designed chiefly for manual operation The object of the invention is to obtain a simple device, that cannot readily get out of repair, and one that may be easily manipulated with but a small expenditure of power J L Ransom, of Charleston, S C, is the inventor COMPENSATING REGULATORS FOR WATCHES Dana Bickford, of Westerly, R I, has invented an improved regulator for watches, which affords great facility for connecting the compensation, as the effective length of the curb is varied, without shifting the curb pins on the hair spring When the compensation is insufficient, it is corrected by simply tightening a set screw furthest from the curb pins; and when it is too great, it is corrected by tightening a set screw nearer to the curb pins; in either case loosening the screw which previously held the curb, so that the curb may be left perfectly free to expand or contract RAILROAD BRAKEThis invention consists in introducing small adjustable auxiliary wheels between the main wheels of the truck, so that when the train is passing around curves, those wheels which are in line with the inward or shortest curve of the track may be suspended above the rails, while the small wheels rest on the rails and perform the office of the large wheels in such a manner, owing to their decreased diameter, as to allow the main wheels of the outward or longest curve to run over a greater length of space in a given time than the small wheels travel over thus compensating for the difference in the length of the inner and outer curves of the track This arrangement of small wheels allows of all the large wheels being suspended, and the speed of the whole train reduced to a mere fraction in a few moments, without danger of one car crowding upon another It is the invention of John C Fr Salomon, of Baltimore, Md Mr S patents, in connection with the above, an improved style of brake peculiarly adapted for his invention We regard this as one of the good improvements of the age IMPROVED DIVING BELLThe principal object of this invention is to establish a communication between the interior of a diving bell and the surface of the water, so that the divers may be permitted to come out of the bell and above the surface of the water at their own pleasure, without the tedious and laborious operation of raising the bell This object is attained by providing the diving bell with a tube or hollow trunk, of sufficient length to extend from the body or working chamber of the bell to above the surface of the water, and of sufficient size for a man to pass through, the trunk being provided with a manhole valve at or near its junction with the working chamber of the bell, and another further up, so that by opening only one of these valves at a time, the descent into, and the ascent from, the working chamber can be effected with a very little loss of compressed air from the bell Benjamin Maillefert, of Astoria, N Y, is the inventor LUBRICATORW Clough, of Madison, Ind, has invented an improved lubricator for railroad axles, which consists in a hand attached to a sleeve, or hub, which is fitted to work on a spindle within the oil box, and which has also attached to it a slotted jointed arm This arm is connected with an eccentric wrist at the end of the axle, the said arm, hand, and sleeve being so arranged that, by the rotary motion of the wrist with the axle, the hand is caused to receive a swinging motion, which alternately dips into the oil in the oil box, to take up a small quantity of oil or grease, and lift it up into contact with the journal, and to deposit the oil so taken up, or a portion of it, upon the journal The invention also consists in making the slotted arm, sleeve, and hand of a single piece of wire, in such a manner that the sleeve constitutes a spring, which enables the hand to rest for an instant against the journal to insure the deposit of oil thereon, and serves to obviate any liability to breakage of the arm or hand, by the concussions produced by their very rapid motion TUEULAE WROUGHT IRON AXLES AND SHAFTSThis invention consists in the manufacture of tubular wrought iron bars for axles, shafting, or other purposes, from a solid pile, by means of rolls, with a system of grooves properly constructed, by which every portion of the iron is subjected to the same degree of drawing and compression, and the bars are rendered much more sound, and of more uniform texture than tubular bars, produced by making a faggot of a number of segments arranged together, with a central opening between them, and then welding and drawing them between rolls This last is, we believe, the only method heretofore practiced of making tubular wrought iron axles, c, and which method, owing to all the drawing effected by means of rolls, being on the outside, with no resistance on the inside of the tube, tends to open the grain of the iron instead of closing it It is the invention of E W Stephens and Richard Jenkins, of Covington, Ky GAS APPARATUSJohn G Hock, of Newark, N J, has invented some improvements in the manufacture of illuminating gas, particularly designed for small gasworks for dwelling houses and public buildings, though they are wholly or in part applicable to gasworks on a larger scale One improvement consists in certain provisions for vaporizing the tar from coal or other gas, and returning it in a state of vapor to the retort, to be decomposed and converted into gas, which improvement is also applicable to rosin oil or other substances in a liquid state, or capable of liquefaction by heat previous to its introduction to the body of the retort, to be decomposed or converted into gas Another improvement consists in a certain construction of the condenser, whereby provision is made for varying the surface of pipe exposed to the cooling influence of the atmosphere And a third improvement consists in a certain mode * of providing for a constant supply of water to ki the channel, by which the sealing of the cover l of the lime purifier is effected \M
