The rapid gtWth of our Patent Agency business during the past three years has required a great addition to oil ordinary facilities for its performance, and we are rcow able to announce the completion of a system whicti cannot fail to arrest the attention of nil who have business of this kind to transact. OUR PRINCIPAL OFFICE will be, as usual, at No. 138 Fulton street, New York. There is no other city in the Union so easy of access from every quarter as this, consequently Inure aro greater advantages in regard to the transmission of models, funds, &c., through the various channels that center in New York. Two of the partners of our firm reside herp, and during the hours of business are always at hand to counsel and advise with inventors. They are assisted by a corps of skillful Examiners, who have had many years of active experience in the preparation of cases for the Patent Office. To render our Patent Agency Department complete in every respect, ire established over a year ago a BRANCH OFFICE IX THE CITY OF WASHINGTON, on the corner oi F snd Seventh streets, opposite the United States Patent Office. This office is under the general superintendence of one of the firm, and is in daily communication with the Principal Office in New York, and personal attention will be given nt the Patent Office to all such case as may require it. Inventors and others who may visit Washington, having business at the Patent Office, are cordially invited to call at our office. A SPECIAL NOTICE. We especially require that all letters, models and remittances should be made to our address atNew York. EXAMINATION OF INVENTIONS. We have been accustomed from the commencement of our business—thirteen yearssince—to examine sketches and descriptions, and give advice in regard to the novel" ty of nsw inactions, without charge. We also furnish a printed circular of information to all who may wish it, giving instructions as to the proper method which should be adopted in making applications. This practice we shall still continue, and it is our purpose at all timea to give such advioe free and eandidly to all,who appy to us. In no ease will we advise an inventor to make application unless we have confidence in At success before the Patent Office. Our extensive experience in mechanical and chemical improvements enables us to decide adversely to nearly one half of the cases presented to us for our opinion, before any expense has occurred in the preparation of the case for a patent. When doubt exists in regard to the novelty of an invention, we advise in such cases a PRELIMINARY EXAMINATION to be made at the Patent Office. We are prepared to conduct such examinations at the Patent Office through our u Branch Agency," upon being furnished with a sketch and description of the improvement. Our fee for this service will be $5. After sufficient experience under this system, we confidently recommend it as a safe precautionary step in all oases before application is made for a patent—not that there will be no rejections under this system. It is impoisible to avoid suchresultain many cases, owing to the exceedingly wide range taken by the Examiners in the examination of cases; but, nevertheless, many applicants will be saved the expense of an application by adopting tliis course. Applicants who expect answers by mail muat enclose stuiups to pay return postage. THE COSTS ATTENDING AN APPLICATION for a patent through our agency are very moderate, and great care is exercised in the preparation of specifications, drawings, &c. No cases are lost for want of particular care on our part in drawing up the papers, and if the claims are rejected, we enter upon a speedy examination of the reasons assigned by the Commissioner of Patents for the refusal, and make a report to our clients as to the prospects of success by further prosecution. A circular containing fuller information respecting the method of applying for patents can be had gratis at either of our offices. REJECTED APPLICATIONS. We are prepared to undertake the investigation and prosecution of rejected cases, on reasonable terms. The close proximity of our Washington Agency to the Patent Office afiords us rare opportunities for the examination and comparison of references, models, drawings, documents, &c Our success in the prosecution of rejected capea has been very grsat. The principal portion of our charge is generally left dependent upon the final result. All persons having rejected cases which they desire to have prosecuted are invited to correspond with us on the subject, giving a brief history of their case, enclosing the official letters,&c. FOREIGN PATENTS. We are very extensively engaged in the preparation andsecuringof patents in the various European countries. Far the transaction of this business we have offices at Nos. 6(3 Chancery Lane, London; 29Boulevard St Martin, Paris; and 2fi Rue des Eperonniers, Brussels. We think we may safely say that three-fourths of all the European patents seen red to American citizens are procured through our Agency. Inventor will do well to bear in mind that the English law does n Dt limit the issue of patents to inventors. Any one can taKe out apatent there. Circulars of information concerning the proper course to be pursued in obtaining patents through our Agency, the requirements of the Patent Office, &c, may be had gratis upon application at the principal office or either of the branches. Communications and remittances should be addressed to MUNN & COMPANY, No. 128 Fulton street, New York. The annexed letter from the late Commissioner of Patents we commend to the perusal of all persons interested in obtaining patents :— MESSRS. Mmro & Co.—I take pleasure in stating that while I held the office of Coiamissioner of Patents, MORE THAW ONE-FOURTH OF Ali TIIK BUSINESS OP TUB OFFICE came through your hands.

PLOWS—William Blacky of Manchester, Pa.: I do not claim either of the individual parti thereof, nor do I claim the precise form of the digger teeth or picks shown and described, as similar ones may bo seen on a patent granted E. F. B-irry, Feb. 10th, 185G. Nor do I wish to IK1 underdtoo'l as limiting my claim to the precise arrangement shown and described of the springs, E, joints, fi, rods, 2 and 3, with the plow, P, and diger,H, as that is susceptible of various other modifications. But I claim thB combining with the plow. P, the adjustable rotary digger, H, having sharp teeth or picks, T, substantially as described, for the purpose set forth. STEAM HEATING APPARATUS—Henry G, Bulkley, of Kalamazoo, Mich.: I do not confine myself to any particular construction of the furnace or apparatus employed in carrying out my invention, But I claim the surrounding of the air passages by a steam atmosphere, to which heat is applied after the steam ia generated, for the purpose of increasing the temperature of the steam without high pressure, for making a rapid, safe, economical and wholesome heat, substantially as specified. [This invention consists in heating air for warming houses, buildings or apartments, by causing it to pans through pipes, passages or chambers, which wholly or partially surrounded a chamber containing superheated steam of a limited pressure. The advantage to be derived from this system of heating air, over that of causing it to pass surfaces heated by direct exposure to the fire and heated products of combustion, consists in the impossibility of heating the pipes or passages to such a degree as to effect any de-oxygenation of the air, or as to be in any danger of setting on fire the building in which it is used, both of which effects often result from the last-mentioned method of heating : and the advantage over heating by steam is that the heating surfaces can be more highly heated without dangerous pressure on them, and hence a less amount of surface is required.] MILL PICK HOLDERS—Jacob P. Brady, of Mountjoy, Pa.: I claim the double socket pick holder, when constructed as described, and used in combination with the diamond-shaped picks in the manner and for the purposes set forth. CORN PLANTERS—John S. Davis, of Arcadia, Ohio : I claim the adjustable guards, M, truck, K, and adjustable hoppers, I, in combination with the adjustable connecting roas, S S, lever, R, and rod, Q, the whole combined, and operating in the manner described and for the purpose set forth. BRIGK MACHINES—J. W. Crary, of New Orleans, La.: I claim, first. The combination of an annular rim or concave moulding surface, with a roller or convex pressing surface, so that the bricks are moulded by pressure operating toward the circumference, and discharged in a direction toward the axis of said concave moulding surface, substantlnlly as and for the purposes set forth. Second, Arranging a pug mill, for the preparation of the dry clay, to work in connection with said first feature of my invention by moans of the gearing described, substantially aa and for the purposes set forth. [This invention has several peculiar advantages. First, the ranking of a concave, on the brick while rotating, instead of a convex, surface on the outside of circle, aa in other machine?, which make the brick on the outer surface of a circle. Second. By means of running the outer surface of the pressing roller to the inner surface of the circle of moulds, a circular and more accurate aagle of contact is formed, thereby saving power and presenting the point of pressure required in the moulds directly in a line with the radius of the pressing roller. Third. This machine supplies itself with clay, which is brought near to it in a dry state, and after making the brick, delivers them into the kilns to the setters, iu good condition for setting and burning. The capacity of this machine can be increased to any extent, from 10,000 to 100,000 per day. This mode of making brick muat, we think, prove to be a decided improvement. It is well known that a great pressure exerted upon any argillaceous pulverized material in a dry state, produces a body more deDse and irresistible than can be made of the same material in a soft, hydrous or pasty consistence, and if brick can ba well made and burned by this mode, they must be superior to those made in the old way.] OPERATING STEAM TRIP-HAMMERS—Joseph S. Bon-ney, of Hanson, Mass., and Charles W. Willard, of Brldgewater, Mass,: We do not claim the combination of a bent rocker lever, an actuator and tyro adjustable cams, appli3d together and to a valve rod and trip-hammer, as represented in the specifications and drawings of the afortmaid patent.

[This invention consists in a certain mode of combining the several parts of the lock, so that a single spring is made to serve in a very effective manner the purpose of main spring and trigger spring, and for keeping in its operative position the dog through which the rotation of the cylinder is effected by the cocking of the hammer, and also for operating the stop which locks the cylinder while the hammer is cocked. It further consists in a mode of applying the rammer in combina- tion with the center spindle by which greater conve- nience is afforded for taking out the center spindle to permit the detachment of the cylinder.] WASHING MACHINE—D. C. Rood, of Altona, 111. : I am aware that rotating cylinders and concaves have been previously used and arranged in various ways for washing clothes, and I therefor do not claim broadly Buch device separately or in itself considered. But I claim having the rotating cylinder, B, provided with a flap or door, f, and a flap or fastening, c, and covered by an inflated band or belt or any suitable cloth or fabric, h, in combination with the yielding concave, D, previded with the corrugated board, F, and rollers, j j, the whole being placed in a proper box, A, andarrangedsubstantiallyas and for the purpose set forth. [This invention consists in the employment of a hollow rotating cylinder, and a yielding concave placed in a suitable box, the cylinder being provided with a plate or door, a fastener or catch, and covered with an inflated belt or a thick fabric of any suitable material.

F F, neither do I claim, broadly, the employment of an adjustable slide, to regulate the amount of seed to be planted at each dropping, for slides have been arranged n various ways for such purpose. I am not aware, however, that a seed slide andadjusting bar have been arranged as shown, so as to form the exceedingly simple device described, to wit. a supplemental seed chamber and adjustable seed slide combined. I claim the seed distributing device formed of the slide, bent or lowered as shown,and the adjustable bar G, fitted in the seed box, E, the whole being arranged and connected with the plow for joint operation, substantially as and for the purpose set forth. [This is a novel adaptation of a seed distributing device to a plow, Khereby the attendant while guiding or holding the plow may actuate at will and with facility the seed distributiag device, the same owing to its peculiar construction being capable of ready adjustment, so that the discharge of seed may be regulated a3 occasion may require.] ANDIRON—J. B. Sargent, of New Britain, Conn. : I am aware that andirons have been made, having a bolt with a screw on the upper end for the purpose of securing the ornamental pillar, and also haviug a shoulder on the lower end passing through the legs and fire-iron and riveted on the underside, which cannot be said to be detachable, nor neither do I claim such. But I claim the construction and arrangement of the legs, A, the fire-iron, Bt the pillar, C D, all secured together by the bolt, E, in the nut, c, in the upper portion of the pillar, D, all of whichcau be readily detached when desired, in the manner and for the purpose a3 described.
