Abstract: 3062. Falkenstein, G. S., and Falkenstein, C. Feb. 12. Coated d fabrics.-Artificial leather is prepared as follows:- From two rolls a, a' are supplied the fabrics b, b<1> which are to constitute the back and face of the artificial-leather sheet B. The back b is of muslin, linen, &c., and the face b<1> of a matted or loosely-felted cellulose material, such as cotton batting.

Granted: 1902-02-27
Abstract: 6362. Chubb, Sir G. H., Chubb, H. W., Chubb, J. E., and Butter, F. J. March 26. Safes; fastenings.-The two sides a, Fig. 1, and the back b of a safe may be formed of a single plate, bent round at the front and connected to the door frame, or two or more plates, connected together by butt-straps c &c., may be employed. The top and bottom are each formed of a single plate d with rounded edges for attachment to the sides by butt-straps &c. f. The corners are cut away and trimmed to bed upon the flanges of cast or forged corner pieces i, the upper surfaces j of which register with the side and front and back plates, which are connected to the pieces i by riveting or otherwise. Another part of the invention relates to means for readily varying the position of shelves, drawers, cupboards, partitions, &c. Holes l, Fig. 7, are made in the lining k of the safe, a strip of metal m being preferably employed to reinforce the lining. A number of plates n, each provided with two pins p<1> on one side and one pin p on the other side, are secured in position by means of the pins p<1>, which take into the holes l. The shelves &c. q are supported by the pins p. The shelves and drawer casings are provided with rows of holes to receive studs r having nicked heads s adapted to secure partitions t. The pins p, p<1> are so arranged that, by reversing the plates n, the position of the pins p is varied, say to the extent of half the pitch of the holes l. In another arrangement, sheet-metal channels are secured to the side linings, and are notched to receive the tangs of bearing-bars, to which the shelves &c. may be secured by legs which take under the bars. Fig. 11 shows an arrangement by which the shelves and drawer casings cannot be removed so long as the drawers are locked. The shelf &c. x runs along a strip w<4> supported by pins &c. p<2>. A latch y, pivoted to the underside of the casing x, is so arranged that, when the drawer is closed, it comes against a stop y<2> on the latch and forces it against the side of a notch in the strip w<4>, thereby preventing the removal of the shelf &c. while the drawer is locked. The projection y<3> may be extended upwardly to be acted upon by the upper drawer.
