First and foremost he exhibits a burglar-proof safe for bankers' use, the door of which is guarded when closed by the most simple and compact bolt work, so constructed that it presents a resistive strength to fracture equal to five times that of any system of train bolts now in use, and this bolt work, with the locks to guard it, is operated by a massive invulnerable welded steel and iron disc, hung upon inner and outer bearings so truly and perfectly that it can be revolved like a top under the slightest pressure, while it is secured so strongly and closely in a corresponding opening in the body of the door that it would require tons of pressure or shock to remove it. The more immediate cause that developed the necessity of this new department in safe construction lay in certain discoveries made by Mr. Gross in the course of his expert occupation of opening safes whose locks had become deranged or the combinations lost by carelessness. He found by experimental test that the various spindles or arbors in common use, by means of which the locks and bolt work were manipulated, could be successfully assailed, so that he seldom consumed more than two hours, and usually about half that time or less, in utterly destroying them and entering the safe. Feeling that such safes could not be conscientiously recommended to the public as burglar-proof, he devised the above described improvement, which entirely does away with the use of spindles or arbors, and with this disc arrangement the safe has then nothing passing through it, and the door and walls are solid alike. Mr. Gross stakes his professional reputation on the merits of this invention, which only requires to be seen to be appreciated; its simplicity is apparent to everyone, and the practical man can readily see that the inventor has simply taken advantage of the best construction to secure maximum strength in the materials used. The locks employed to secure this safe are the result of much study, and are most admirably adapted to the purpose. The time movement and permutation tumblers are closely connected within a space of two inches square, and perform all the functions of the ordinary bulky time and combination locks of ten times the size while possessing new features of convenience and security that will be readily appreciated by users. Mr. Gross also finally presents a fire-proof safe, of excellent design and calculated per maximum efficiency in the protection of its contents from fire. All the inventions of Henry Gross, from his first "time lock," show the master's hand of genius, and now that he has practically demonstrated the excellent and invulnerability of the two last efforts of his skill, it is sincerely to be hoped that bankers, county treasurers, and those who use safes generally, will look at the merits of his make before they buy the productions of mendacious manufacturers, whose main merits consist in the liberal use of printer's ink. If Mr. Gross' executive and financial abilities were equal to his genius, he would have been a millionaire long since."
