The following inventions have been patented this week, as will be found by referring to our List of Claims : COMBINED BOOTJACK AND BURGLAR ALARMThis invention consists in the use of two adjustable movable jaws and a spring treadle, attached to a bed or plate, and used in connection with a catch These parts are so arranged that the treadle is made to perform the double function of operating the jaws when forced down by the foot, and the implement used as a bootjack, and also of sounding an alarm when the apparatus is used for that purpose and placed in proper position against a door F C Goffin, of Newark, N J U the inventor CKOSSCUT SAWING MACHINEThe object of this invention is to obtain a simple and economical device for sawing logs transversely into suitable lengths for firewood ; one that can be operated by hand with a moderate expenditure of power, readily adjusted to the log, and easy of manipulation generally H H Potter, of Carthage, N Y, is the inventor REMOVABLE RAMROD FOR REVOLVERS This invention relates to tliat description of revolver whose chambered cylinder rotates on an axis parallel with the bore of the barrel It consists in a novel, simple and effective method of applying a rammer to ram the charges in the chambers of the cylinders, and is the invention of H S North, of Middletown, Conn, assignor to Edward Savage, of the same place SPLITTING WOODFranz Noette, Brooklyn, N Y, has invented a machine for this purpose, which consists of an intermittingly rotating table and plunger provided with cutters, arranged so that wood may be sawed into proper lengths and split into kindling wood with great facility SAW GUMMERM Ernsberger, of Bremen, Ohio, has invented an improved device for this purpose, which consists in the employment of a stock provided with set screw clamping it to the saw, in connection with a burr cutter peculiarly constructed and applied to the stock in such a manner that the same may be properly guided or held in proper position while in operation, and also fed to its work with the greatest facility, the whole forming a simple and efficient implement, well adapted, and more especially designed for gumming circular saws GAS PIPE COUPLINGThis invention consists of an open coupling for gas and water pipe, whereby the necessity of cutting away a portion of the main pipe and forming a running joint to attach the branch pipe is avoided The operation of attaching branch pipes is also greatly facilitated, and labor and expense lessened, and facilities for cutting off the supply by detaching the branch and plugging up the main, likewise afforded This is certainly a simple and good coupling, and is the invention of W Hudgin, of Washington, D C PROTECTING TILLER ROPES OF VESSEL3 FROM FIREShould a ship take fire, so long as the rudder is under the command of the pilot there is a chance to still preserve the passengers and cargo, but the moment the tiller ropes are burnt the ship must be given up to the mercy of the fire, and the tempestuous waves This invention is designed to prevent this calamity by fitting the tiller ropes in metal tubes, which are again enclosed in tubes of larger diameter, so that a space is left between them that can be filled with any nonconducting material These tubes are to extend from the wheelhouse to the tiller, so that the whole length of the ropes will be protected W Y Gill, of Henderson, Ky, is the inventor ICE PITCHERThis invention relates to that description of pitcher which is surround ed with a hollow jacket, or, in other words, is provided with double bottom and sides Such pitchers as usually constructed, have the inner part or lining soldered or otherwise attached at the top part of the outer casing, and in consequence when the inner part or lining is worn through or accidentally perforated, as it generally is, while the outer part or lining remains good, there is no, or very little, facility for repairing it, and the pitcher becomes in a measure worthless Ernest Kauffman, of Philadelphia, has invented one which consists in fitting the inner part or lining into the outer part or case, with screw threads or their equivalents, which provides for making a tight joint between the two parts when together, and for the ready removal of the inner part or lining for the purpose of replacing it by a new ona or repairing it when damaged FILE CUTTING MACHINEIt has often been attempted to cut files with accuracy by machinery, but we are not aware that any of the devices proposed, have been able to overcome the chief difficulty until the one of which we will try to give some idea, was invented by J Nelson Jacobs, of Worcester, Mass This difficulty is, that all files having somewhat of a curved profile, when they are cut with a chisel having a definite stroke, it cuts deeper into the raised part of the curve than any other part, and so weakens the file, now this machine cuts the file to the same depth, whatever be its profile, by means of a profile model which acts as a stop to the chisel, and so allows it to cut only the right depth the whole length of the chisel Fine or coarse chisels can be cut with equal facility on this machine, and also any size We have seen some files which have been cut by this machine that were to all appearance equal to any hand cut, and much more regular in the distances of the serrations REEFING SAILSIn most of the plans heretofore used for reefing topsails from the decks of ships, the sail has been rolled on a roller, or, as it is termed, a "jackyard," attached to the yard, to avoid the necessity of dividing the sail vertically, as has been done in most, if not in allcases where the sail has be(in rolled on the yard itself The advantage that would result from rolling the sail upon the yard itself, if it could be done without dividing the sail, and the yard be made to work freely, are very generally admitted by nautical men, and the object of this invention is to obtain this result The method which the inventors, Lewis Higgins, of Jersey City, N J, and Alexander Brown, of New York, pursue to attain this end is simple They suspend the yard by means of a double Cshaped truss frame from the mast, and between the two C's a number of small rollers are placed in which the yard can rotate freely and between which and the yard the sail can be snugly coiled Thus all necessity for dividing the sail is taken away, and a very good and simple method of reefing sails from the deck is provided RAILROAD INDICATOR This invention consists of a transparent faced box placed in each car In this box two square rollers with a flexible endless chain of cards having the different stations printed on them, are arranged A forked lever extends down from the upper roller to the rails of the track, and comes in contact with inclines at the different stations These inclines raise the lever, and cause it to turn the upper roller, and thereby bring cards separately and successively opposite the transparent front of the box When the card thus appears to view, the passengers read the station to which they have arrived With this arrangement provision is made for sounding a bell to call the passengers attention as soon as the card comes in view The endless chain of cards is operated both in the forward and return trips of the train This appears to be a very useful and perfect arrangement, as much confusion and annoyance to passengers and conductors will be avoided by its use in cars John M Harvey, of Am f sterdam, N Y, and N J Becker, of Florida, 0 N Y, are the inventors (f
