The Mining and Scientific Press. Latent Department. Cotsurn’s Lane Pit.er is ono of the many useful inveations which have becn brought out since the introduction of Kerosene as a burning finid. It may be applied to every lamp now in use, at a trifling cost. It ia a very neat anil convenient arrangement for oh viating the disagrcenble necessity of unscrewing and taking off the top of the lamp to fill it. This “ filler” is placed between tho burner and tho collar of the lamp, aud consists ofa hinged apparatas, by which on touching a spring, the chimney and burner is made t+ turn down in such a manneras to allow the nozzle of an ordinary lamp filler to be inserted into the oil chamber of the lamp, which is then readily filled. ‘The invention has already been introduced into this city and is both ncat aud convenient. Porservine Inox rrom Conrosion.—G. W. Holley of Niagara, N. Y., hus secured Ictters patent for a peculiar composition for protecting iron from corrosion. Favrr Prrss—A Cauirorxia Invention.—John Manrow, of Sacramento, has patented and improved Fruit Press, the peculiar combination and working of which we should be happy to describe if the inventor would furnish us with the data. -Woopen Pavexent, by Samuel Nicholson, of Boston, Mass., originally patented, August 8, 1854. We have recently given a full description of this improved wood pavement, togcther with certain facts in relation to its successful introduction into several cities. We notice that a re-issue of this patent has recently bcen granted. Tue Maxuracture or Srrei.—dMessrs ‘Brant & McElroy, of Pittsburg, Penn., have recently discovered and pat nted a process for manufacturing steel: direct from pig iron, in an ordinary puddling furnace. Tbey throw into the furnace pulverized charcoal, or otber carhan, when tbe iron begins to granulate, and close up the furnace so as to retain the gases evoled therein, as described in their spccificati. n. Srririts or Turpextine.—Mr. L. S. Cole, of Burlington, Vt., has secured a patent for a new process for producing Spirits of Turpentine and other analegous oils direetly from the wood, usiug for tbat purpose machinery as described in his application, A caveat for accomplishing similar results has also been recently taken out by a purty resident in this State. through the Misine axp Scuentinic Press Patent Agency. (The party in whose favor said caveat has been secured is requested to communicate with this office.] Krver, the great. stecl manufacturer of Germany, is mannfacturing cannon of immense power. They are 9-inch bore, made of cast, steel, and throw a 300-. pound slicll of 22 inches in length, or a 450-pound sbot, with a 50-pouna charge. Srovrs made of soapstone have bcen introduced at Quebec. Thcy are said to throw out mellower and more uniform heat than iron; the material of which they are made is very abuudant iv the mineral region Sabre! of the St. Lawrence. The Mining ‘and Scientific Press Patent Agency. OFFICE, 57, GOVERNMENT HOUSE, SAN PRANCISCO, Information About Obtaining Patents. The Patent Law Amendmont Act, of March 4th 1861, and Mareh 3d 1863, now in force, Introduces several {mportnnt ehanges In our Patent System. The gencral practice of the Patent Office, however, In regard to the examination aud issue of Lettora Patent for new iInvendons, remains nearly the samo as heretofore. The amendinent of 31 Mareh, 1863, provides, Insectlon 3, ihat every patent shell be dated os of a day not later than six months after the time at which It was passed and nliowed, nnd notice thercof sent to the appilcant or hlsagent, And If the final fee for such patent be not pald within the sald six months, the patent shali be w" itheid, aud the Inyentlen thereln deseribed shall become pubiic property as against the npplicant therefor: Provided, That in all cascs w here patents have been allowed previous to the passage of this act, ‘the eald six months shall be reckoned from the date of such passage. . The first question, therefore, that presents Itself to the Inventor, . $20. who desires to procure a patent, is: "Can Fobtaina patent? A positlye‘answer to this quésiion-is oniy to be had by presenilug a fyrmal application for patent to the Goverument,embracing a pelltion, spect/ fication, model, duplicate, drawings, andthe payment of the pre. aertbed ofltetal tees. Axle froin these steps, all the Inventor enn do Is, to subiall hls plivs to persons expericnecd In the bushice: of ohtaining patents, and solicit thelr opinion and advice. If the partles consulted are honorable men, the inventor may safely confide his Ideas to them, aud they will Inform him-whether or not lls nveution Is probably patentable. Thos: who have made Inventlons nnd desire to consult with us respeeting Ihe sane, are cordintly Invited to do su. We shall be hap: lly to ace theiu In person at onr ofilce, or to advise them by mall, or (rough the Sitxine ann Sctrsmivic Press, Inall cuses they nay expeet from us nn honest epinion, For thesy consultations, opinion and advice, we make no charge. Apen-und-ink sketch, and descrip" ton of the Invention should be sent, together with a stamp for return pestage. Write plain ; do not use pencell or pale Ink ; be brief. Remember that all business coinmitted to our enre, and nll consul. tations, are kept by us seerct, and strictly confidential. Preliminary Examinations, tn some. cases it may be advisable ns a incasure of prudence to erder preliminary examination. This consists of a special seurch, Tae ut the U. S. Patent Office, Washingten, throngh tte medium of our assoclate In that clty, to ascertain whether among all the patents und models there stored, any Invention can be tound whieh Is siinlfar In characier to that of the appHeant. Ou the completion of this epecial search we send a written report to the party concerned, with sultahle adviec. Our charge for this servlec, Including the report, istendollars. This search, though It Involves the expense just Named, will usually prove sutlsfnetory. If yhe sume device has been before patented, the tine and expense of constructing models, preparing documents, etc., will In most eases be saved ; If the nventlon has been in part patented, the applleant will be enabla to mod” Ify his claims and expectatlons accordingly. Many other obvions advantages attendIng the Preliminary Examination ; nithough the strletest search docs not always ennble the anplicunt te know posltlyciy whethera patent can be had. Applications for paten!s are often rejected because tho Exainlning officer finds a escription of the alleged Invention In some forelgn publleation ; or some other person has beon previousty rejected on an analagousy device ; or some other Invention for a similar purpose, but partially resombles the applicant's in its construction ; or the Gavernment makes un unjust or uncomnion decision. Agalnst none of these contingencies does the Preliminary Exninination provide ; {t will, however, generally Inform the applicant whether an improvement.similar to his aud used lor the saine purpose has ever been patented or not In this eonuiry. Persons desiring the Preliminary examination are reqnestod to remit the fee ($10), aud furnish us with a sketch and description of the Inventlon. Caveats. ‘A Caveat Is n confidential communication made to the Pntent Office, and Is therefore filed within Its secret archives. The privilege scenred under a caveat is, that It eutitles the eaveator toreceive notice, fer n perivd of ene year, of any application for a patent snbsequently filed, and which is adjudged to be novel, and is likely to Interfere with the Invention deserlbed in the-cavent, and the cnycator js then required to complete hls application for a patent within three months trom the date of sald notice, Caveat papers should be very carefully prepared. Our fee for the servlee vnries from $10 to Tho Government fee under the new law is reduced to ten dollurs ; and this sum does not apply, as heretofore, as part of the fee on presenting an application tor a patent. Inventors wiil oftimes find It very important to take advantage of the eavent system—the expense uuder. the law belng comparatively small. To enable us to prepare eaveat paper, we only require a sketch and description of the Invention ; no model being necessary.Expense of Applying for a Patent, Rejections, ete. Under the new law, the Government fec, on filing an application for a patent, ts tteen dollars 5 and If the patent is allowed, twenty dollars additlonal Is required. If rejected, the first fee of filteen dollars is all that ig demanded. English, French, Austrian, Prussian, Spanish, nnd inventors of every nationality, may now ebtain patents m the United Stntey npon the sanie terms as our own citlzens. The only discrimiuatlon made 1s against subjeels of governments that diserlminate against the Inhabitants of the United States. To the foregoing official feces must be added the Attorney’s fees for Preparing the vnrious dcexuments and druwings. Our charge for preparlng a case, prescntlug it to the Government, nnd attendIng to alt busIness counected with It, until n deelsion Is given, Is from $20 to $10. If the patent is granted no further agency expenses ensucs.— If the application !y rejected we cruse a thorough Investigation to be made Into the reasons p d to the Com for refusing the patent. ln making this examination, we have excess to all the drawings, models, books and specifications cited In reference, and we report the result as earty ns possible to our clicnt. For this ser, viee we make no charge. If the rejeciion proves !o be an ujust one—which sometimes happens—it ean gencrally be reversed, and the patent obtalned hy contesting the case. For this prosecution we charge a fee proportionate to the extra labor involved, payable only on the issue of the patent; but our deinaad will be retsonable aud satisfactory to our elients, and will be arranged beforehaud by specinl agreement. The systein adopted by us works well, gives general. salisfaction, and presents to wll applleants, rich or poor, an equal opportunity ; ot having their patent cases prepared, conducted and prosecuted in the best manner, by expericuced attorney's, upou the; most moderate terms. Inventors wilco have rejected eases, prepared cither by them selves, or for them by otlicr agents, and desire te nscertain their prospeets of snecess by further efforts, are invited to avail tiemsecl yes of our uncqnatled lacilitics In.securing favorable results. Wo have been successtul in securing Letters Patent in many cases of such a matter. Our terms for such cases are very moderate. Models, Remittances, etc. The laws requires that the inventor shall, In all cases, furnish a model, which inust not exceed twelve inches in any of Its dimentlony; It$hould be neatly made, of bard wood or inctal,-or both varnished or painted ; the name of the-inyventor should be wearin or painteil on it conspicuously. When the invention consists of an Improvement on some known 39 may be forwarded Gees by expres with the model, or fe ot — The eafest wuy to remit is by draft on San Franclaco, Tnynble to our order. Alwnys send a letter with the nivdel, and also the remittance statlig tho name and address of the sender. A tull description shonld also be sent with the model, embedylng all the Meas of the Inventor respecting the Improvement. On the receipt of the model and Government te, the case ia duly eglstered upon our books, nud the application proceeded with aa fast as powlble, When the documents ary ready we send them to the inventor by inail, for his examination, signiture and aftidayit, with a letter of instruction, ete, Onr tee for proparing the case fs then duc, and wlll be called for. The case wlll then bo presented to tho latent Otdee, and ns soon as the patent ls ordered to bo Issued, the appilcant will be notified to remit tho last lastallmont of the Government tee, namely, twenty dollars. Inventors who do business with bs will be notlfled of Ihe state of Ihelr nppHeatlon In the latent Otlicc, when It ly possible for us to do so. We do not reqitlre the personal attendanee of tho Inventor, unless It 1y one of great eomplleation ; the business ean be well done by correspondence, When the Invention conslsts of a new artlele of manufacture, or nnew composition, sainples of the separate ingredients, sulficient to make the experhnent, nud also of the munnfactured article itself must be furnished. * The average time required to procnre a patent, when tho case Is eondncted at onr agency, Ia three months. We frequently get them throngh !n less time ; but In other cases, owlng to uclny on the part ef officinis, the perlod ls sometimes extended to four or flve monthe, andeven more, We wake a special polut to forward eur cases as raplily as possible, Retarn of Models. Under the new law, If the apnlleants easo has been rejected he Is entitled to withdraw his model trom the Patent Offiee. This Inw appiles to all past reflected cases, and If partles wish to ebtaln thelr models throngh us, they can do so at a small expense Application for Patents, Designs, Trade-Marks, Labelis, eto. r Under the new Jaw patents may be taken out for any new fori of any article, also for tools, patterns, castings, machine-frames, stoveplates, borders, fringes, ali new designs for printing, weaving or stamplng upon silks, calicocs, carpets, oi!-cloth, prints, paper-hangIngs, and other articles. Trade-marks, labeis, envelopes, boxes and bottles for goods, may also be patented ; Ikewise all works of art, lnclnding prints, paintings, busts, statues, bas-rellef, or compositions In alto, or basso rellevo, new dies, unpresslons, ornaments to bo placed upon auy article of manufuetnre, arch{teetural work, etc. Onr Incilitles for the prompt preparation and securing of palents are of the most extenslve character and our charges are Mn moderate. Patent Office Fees, and How Payable. Nearly all the fees payable to the Patent Office are positivoly re+ quired by law to be paid In advauce. For the sake of uniformity nnd eonyenlence, the remaining fees will be required to he paid In the same mnnner; that is to say, before the labor Is performed for whieh they are to be reee!ved ln payment.
