A MODERNIZED WATER CIGSK

An Interesting Arrangement For the A

atcur to Try Ilia Hand At,

In these’’piping" times of unerring pro fclsiou of rate, of a timepiece, no mm v.u - 1 naturally expect that a mechanism of thi.Jtind should go unfalteringly and absolutely correct. In fact, it will probably require to bo treated in conformity with the advice of Captain Cuttle —viz, to “wind it once a day and move the hands forward about 15 minutes every' morning and likewise 15 minutes at night, and you’ll have a watch on which you can rely.” A description of this mechanism, found In a German work, is given by The Jewelers’ Circular as follows: “A thin arbor A rests upon two supports, S Sl—a straight and truly round knitting needle will answer the purpose

A WATER CLOCK, well. Ouo of its ends protrudes beyond the dial fastened at bU and carrier) a hand. TJie hours only arc marked upon the dial, and consequently this The only hand Is the hour baud. •■About in tho middle of tho arbor A la fixed a pulley, E, with a deep groove. Around this pulley is wrapped a thread, one cud of which carries a cork float, F, whilo a small center weight is attached to the other end. Exactly underneath tho float F is a so called 1 tulip’ glass, which is filled with water to (ho rim when the clock is started. A conduit, an ordinary cotton wide, M, passes into an empty cylindrical vessel, li, which stands close by. “■The natural consequence ensues. Tho wick M acts to a certain degree os a siphon, absorbing the water In tho glass E and discharging It into the lower vessel, R. In consequence of this the former empties slowly, while tho latter fills gradually. Tho sinking of the water- level naturally produces the sarao with tho float F, thereby actuating tho pulley B, the arbor A and tiie hour hand C. By a suitably large pulley, B, tho hour hand can bo made to revolve in an approximately correct time.” In spite of some difficulties, such ns getting a glass of exactly tho correct shape and th.o pulley of tho right size, readers of a mechanical turn of mind may find entertainment in endeavoring to construct this imitation of a clepsydra, or antique Roman water clock. Scrap Steel I’.oiled Into Shape. A process has been discovered by which scrap steel can bo heated and rolled into shape, according to an exchange. Tho secret of the invention is n mineral compor.a'on, which, birnd-rd witli certain chemicals uad mixed with the? scrap, ettlilies tho lua.iS to he heated, foiled and •■.•elded without melting.
