April 20, 1872.] SCIENTIFIC PRESS. 249 Patent Can-Opeuer. Tho varicty of canned fruits, meats, fish and vegetahles consumed hy the civilized world is constantly increasing, while the amonnt annually conenmed is already munch greater than is generally snpposed. Tho cheapest receptacles for putting up suoh preserves aro tin cans tightly solder/ ed, and consequently the hulk of onr canned goods are so sealed, To furnish the best implement, at a moderato cost, for opening these cans, has called into requisition mnch invontive ingenuity, and various dovices havo boon patonted, some of which seom to answer tolerahly well the purposos for which they wore intended. To produce the hest can-openor, in all respects, however, scems to havo beon left to a California artisan, who patented the one hore represented in 1870. It cuts eithor a ciroular opening or a square ono, as may he desired. To make a round cut, a8 in openiug an oyster can, the roundod point is thrnst downward through the top, and the handlo lowered so as to bring the circular cutting knife, (which slides on the bar, in ordor to regulate the size of tho opening,) down to the surface of the can, when with a slight pressure its point will enter the can, and when the handle is drawn around, the cut is casily made. To make a square opouing, as for instance in a sardine box, the instrnment is inverted, and the straight cutting knife at tho point is inserted, instead of the ronnded point, when by an up and downward movement of the handle, acting as a lever, a straightforward inoision is made. The flat spring over the har holds the sliding knifein place. Itis a simple, easily handled instrument, comparatively indispensable for family use, and especially serviceahle to hotels, restaurants, ships, etc. Tinners and saddlers also find them quite useful in theirtrades. Eugene F. Dewey, formerly of San Francisco, is the inventor. Weister & Co., patent salesmen, No. 17 New Montgomery street, are general agents for the Pacifie States, and can be addressed for agencies. For information to distant readers we will mention that samples are sent, post paid, for 75 cents, in currency or postage stamps. Uran Mrves.—The mines in Little Cottonwood are doing splendidly, snd the Kmma, Flagstaff, Wellington, Davenport, Montezuma, Lexington and Savage have a large amount of ore on hand ready for shipment as soon as the weather will permit. A number of snow slides have occurred in the canon, recently, resulting in loss of life and injury. The heavy storms have caused snch an accumulation of snow that great fears are entertained of futnre slides, and preparations have heen made to prevent accidents as far as possible. A number of capitalist8 and experts are in readiness to make examination of several mines as soon as the weather will permit them to leave Salt Lake City. Samples of gold quartz have heen brought to that place from Little Cottonwood, which look well. Pacuric Coast Mzacantine Drrector.—This is the name of a new publication, several epecimen pages of which; have been laid upon our table and which will be issued at an early day. This paper hae been started maiuly through the instrumentality of Mr. William H. Murray, business manager, who has been for eeveral years a travelling correspondent of this journal, and to mcet a primary want which he found to exist for a medium of communication between the merchants of the interior and the wholesale dealere of this city. Each numberof the paper will comprise from 16 to 32 pages, according to the demands for advertising space, and will be furuiehed regularly to interior merchants, bookkeepers, etc., at the rate of $1 for 12 months. We presume the paper will be issued mouthly, Among its contributors are such meu as Prof, E. 8. Carr, of the State Uuiversity, R. G. Sneath, etc., while quite a number of our leading business men have allowed the uee of their names ag promotere and encouragers of the enterpriee. We understand that the advertieing columus of the first number are fast filling up. The Spiral Spring Pencil Sharpener. The accompanying illustration represents a neat device for sharponing lead pencils so as to make a fine point, withont having to soil the fingers in so doing. It is made in two parts, the guide, which is placed upon the pencil, and a oircular cntter raised upon a wooden stand. The stand is made bowl-shaped so as to collect the lead and shavings. The guide consists of a tube having a revolving spring within it, whioh clasps the pencil, allows it to tnrn inside the tnbe and at the same time prevents its slipping. One surfaco is beveled, so that part of the pencil may project sufliciently to bo subjected to the cutter, and by being tnrned by the hand. preseut a different surface to the cutter, until it tapers to a fine point. The disk or outter is a fixtnre upon the wood, but the metal cap which covers it is movahle. Upon the oap is a rest, ealled tho guard, into which the guide is placed. A portion of the blade, or cutter, is exposed by the cap being cutaway. The Geological Survey. The members of the Geological Survey are all busy pursuing the various duties allotted to them by Professor Whitney, and it will not he long before the State maps arocompleted. We spoke a short time since of the map of the Plioceno rivers, which, when finished, will he particularly interesting as showing the localities of the deep gravel deposits of the State. The geological map of the State is in the engraver’s hands; a large portion of it is finished. The rocks of the whole State have been geologically located. One of the interesting features of this map is the colored portion showing the direction and location of the auriferous slate rock, chiefly of Jurassic age, which runs out to the ocean near Oregon, inclnding the auriferous gravel hasins of the Klamath and Trinity rivers. Some of these same slates are now on the top of Mt. Dana. Another. interesting point is that it distinetly shows the regnlarity with which one formation followed the othor in a sort BURGESS’ guide is worked back and forth over the cutter, so presenting the peneil to be cut off until the point is made. The cutter is of fine saw steel and has a very sharp edge. When that part of the blade in use becomes dull, by moving the cap slightly a new edge is presented, which may be repeated until the whole circumference of the entter has become dulled. Itis then only necessary to take out the screw, remove and sharpen the blade, and replace it. This device is intended for Fabers’ pencils principally, but will sharpen any which will enter the spring. It will be found useful in banks, counting-houses, sohools, families, etc., and especially con-. venient for ladies whose pencils are pro-. verhially hlunt, and whose pen-knives are seldom sharp; moreover it will not soil} the fingers. The principal parts of this invention have heen patented, and the patent covering the remainder is pending. Huhert Burgess is patentee, and J. Stott, 1,002 Market street, is agent. Seruinc Mux.—Some German papers are urging that milk be sold, like spirits, according to the percentage of the valuable constituent. Both sellers and purchasers of spiritsare satisfied with this method, as would be also both sellers and purchasers of milk. The advantages are manifest, so much so that one editor thinks it necessary to allude to one only,—that there SPIRAL SPRING PENCIL SHARPENER. of land-making process toward the west. It is very practically shown and applicable in connection with the Pliocene rivers, the formations corresponding to which are traceable all over State, in the valleys far removed from the Sierras. This map is to be properly colored to represent the different geological formations and as soon asthe different plates are made the map will be issued. The Pliocene river map is a distinct and separate publication. Another edifying feature is that which shows the distribution of the lavas of the State, where the activity of volcanic action existed and where it thinned out. Prof. Whitney will leave this week with a party for the region of the late earthqnake. He intends investigating the phenomena connected with this great convulsion of Nature and the effects produced on the conntry surrounding what is supposed to have heen its central or starting point. The results of these observations will douhtless be of great public interest and we anticipate with pleasure the pernsal of the data which the Professor will collect. He hus made the stndy of the subject of earthquakes 2 specialty, and his investigations will be of a strictly scientific nature. His familiarity with the geology and physical geography of the State peculiarly fit him for the task he has undertaken and his statements may be looked onas reliable would then be ‘‘no necessity among dairy-. .n4 valuable. men of raising milk-water-giving cows and. of making the eattle sick.” Coau.—During the month of March 15,200 tons of coal were shipped from the Pitishnrg Coal Company and the Black Ramroap District.—The Highland Silver Mining Co. are eaid to have etruck a fine body of rich ore in the Humboldt mine in Railroad District, Nevada. The Elko mine has also developed a good body of ore. The mines are Diamond Coal Company’s mines at Mount . ali looking well but there is still plenty of snow Diablo, Contra Costa Co. to contend with.

Scheuner, Salt Lake City, Utah Ter., antedated April 3, 1872, a i: Infringements of Patents. A snit has been recently instituted by Frank O. Fisher, against R. B. Craig and Joseph Craig for alleged infringement of patent of the ‘‘ Hydraulie Chief” nozzle. The plaintiff claims that he has with the knowledge of the defendants heen manufacturing and selling the said apparatus, and that notwithstanding this the defendants, contrary to his will, commenced to sell the improvement in October, 1871, and have continued to do so up to the present time. The patent, which is well known, consists of a swivel-jointed nozzle and pipe combined so as to form a double movement; the nozzle proper having a perpendicular movement, while the swivel joint proper enables the entire apparatus to he tnrned by a horizontal movement, in any direction. Between the upper and lower elbow composing this joint is a space left for the insortion of packing hetween the flanges, in order to be freely turned on the elhow, and still form a water-tight joint. The plaintiff prays for damages to the amount of $5,000. John L. Stevens and Geo. W. Stevens have entered suit against Geo. W. Swau and Oliver Hinckley. Complainants state that they are the inventors of a new and useful improvement in cases for transporting eggs. It consists of a box or case, divided into compartments of such a size as to hold one egg each, the box of any depth, placing a separate diaphragm horizontally hetween each tier from the bottom to the top. Complainants further show that in an action at law against Henry Cohn and Charles Martin, in October last, for a violation of the exclusive privilege secured to the plaintiffs, the jury of the United States Circuit Court returned a verdict of guilty, and awarded damages in the sum of one dollar. The defendant herein—Swan &Co.— have manufactured and sold these boxes since February, 1867, and that without the consent of the owners of the patent. Plaintiffs pray that the defendants may be compelled to make a showing of their husiness in the shape of egg-hox manufacture, and that they mayhe decreed to account for, and to pay over to them all the gains and profits which may have accrued to defendants from nsiug, making and vending said impr ovement. Tur excitement created hy the discovery of placer diggings in Lake county has ahated.
