THE UNION IRON MILLS, Pittsburgh, Pa., Manufacturers of improved wrought iron Beams and Girders (patented).

The great fall which has taken place in the prices of Iron, and especially in Beams used in the construction of FIRE PROOF BUILDINGS, induces us to call the special attention of Engineers, Architects, and Builders to the undoubted advantages of now erecting Fire Proof structures; and by reference to pages 52 & 54 of our Book of Sections-- which will be sent on application to those contemplating the erection of fire proof buildings--THE COST CAN BE ACCURATELY CALCULATED, the cost of Insurance avoided, and the serious losses and interruption to business caused by fire; these and like considerations fully justify any additional first cost. It is believed, that were owners fully aware of the small difference which now exists between the use of Wood and Iron, that in many cases the latter would be adopted.

We shall be pleased to furnish estimates for all the Beams complete, for any specific structure, so that the difference in cost may at once be ascertained. Address

COTTON MILLS AND MACHINE SHOPS

Can make great savings by using the Allen Governor. Its operation is unequalled and wonderful. Nearly all machinists once using these Governors become agents for their sale. They are simple in construction, not liable to get out of order, permit the speed of the engine to be changed at will, are neat in appearance, noiseless, very durable, save the engineer's time, save fuel, and are at once the most powerful and most sensitive Governors ever made.

Russell (Cotton) Mills, Plymouth, Mass., March 20, 1876.

S. B. ALLEN: Your Governor has been attached to our Corliss engine over one year, and has given perfect satisfaction. The engine was never governed until yours was attached, although we have tried three of the best kind of Governors known. When steam or work varied, the speed would vary, and we could only run our looms an average of 103 picks per minute. Since using your Governor, and solely on account of the perfect steadiness with which it holds the engine and machinery, we are enabled to run the looms regularly 112 picks per minute, MAKING AN ACTUAL INCREASE OF OUR ENTIRE PRODUCTION OF OVER EIGHT PER CENT. Your Governor saves coal, saves waste, saves care and labor of the engineer, and produces more goods and better goods. I have timed the engine a hundred times, and never found it to vary in the least. It is the honest truth that the Allen Governor holds it exactly on speed.

PATENTS

CAVEATS, COPYRIGHTS, TRADE MARKS, ETC.

Messrs. Munn & Co., in connection with the publication of the SCIENTIFIC AMERICAN, continue to examine Improvements, and to act as Solicitors of Patents for Inventors.

In this line of business they have had OVER THIRTY YEARS' EXPERIENCE, and now have _unequaled facilities_ for the preparation of Patent Drawings, Specifications, and the Prosecution of Applications for Patents in the United States, Canada, and Foreign Countries. Messrs. Munn & Co. also attend to the preparation of Caveats, Trade Mark Regulations, Copyrights for Books, Labels, Reissues, Assignments, and Reports on Infringements of Patents. All business intrusted to them is done with special care and promptness, on very moderate terms.

We send free of charge, on application, THE SCIENTIFIC AMERICAN HAND BOOK, an elegantly illustrated pamphlet of 48 pages, containing further information about Patents and how to procure them; directions concerning Trade Marks, Copyrights, Designs, Patents, Appeals, Reissues, Infringements, Assignments, Rejected Cases, Hints on the Sale of Patents.

_Foreign Patents._--We also send, _free of charge,_ a Synopsis of Foreign Patent Laws, showing the cost and method of securing patents in all the principal countries of the world. American inventors should bear in mind that, as a general rule, any invention that is valuable to the patentee in this country is worth equally as much in England and some other foreign countries.

Five patents--embracing Canadian, English, German, French, and Belgian --will secure to an inventor the exclusive monopoly to his discovery among about ONE HUNDRED AND FIFTY MILLIONS of the most intelligent people in the world. The facilities of business and steam communication are such that patents can be obtained abroad by our citizens almost as easily as at home. The expense to apply for an English patent is $75; German, $100; French, $100; Belgian, $100; Canadian, $50. Address
