Title: Improvements in or relating to Self-acting Mules.
Inventor: HANHART LUCIEN
Filed: 1900-07-24
Granted: 1901-07-24
Abstract: 13,354. Hanhart, L. July 24. Mules.-Means are provided whereby the backing-off chain is drawn tight before the winding-faller begins to rise at the end of the inward run, so that the rise of the faller shall depend on the rotation of the tin roller and so on the revolution of the spindles, in a manner similar to that in which the depression of the faller wire is governed by the revolution of the spindles during backing-off. Several arrangements are described. In Figs. 3<2> and 3<3>, a spring brake lever p is applied to the disc d of the backing-off scroll and holds the disc in the position it occupied immediately the backing-off was completed. During the inward run, the disc d is held stationary with the backing- off chain c tight, but, after the faller has risen, and the carriage begins to move outwards, the brake lever p is disengaged by means of a small supplementary lever t<1>, r', and a stop or slide k in the manner shown in Fig. 3<3>, the release of the brake lever p allowing the disc d to turn to the extent allowed by the usual curb chain a previous to the next backing-off operation. In Fig. 4<1>, as the carriage approaches the end of its inward run, the disc d is rotated so as to tighten the chain c by means of a spring lever p. In Fig. 5<1>, a lever p carries a pair of pulleys m, n, which are connected by chains k, k<1> respectively to the axle of the disc d and to a fixed part of the frame. During the greater part of the inward and outward run the chain c is held tight as shown, but is allowed to be slack as the carriage approaches the end of the stretch by reason of the lever p running on the slide or support k<2>. In the arrangement shown in Fig. 8, a spring brake lever Q<11> is allowed to engage with the disc D, or caused to be moved away therefrom according to the movements of an antifriction roller on the axle of the pulley Z' over which the backing-off chain passes. The braking of the disc depends therefore on the locking and unlocking of the faller wire.

Patent GB-190101101-A (GB)
Title: Improvements in and connected with Photographic Dark Slides and Change Boxes.
Inventor: BROOKS ARTHUR AUGUSTUS
Filed: 1901-01-17
Granted: 1902-01-17
Abstract: 1101. Brooks, A. A., and Watson, G. A. Jan. 17. Change-boxes.-Relates to a change-box chiefly adapted for films, and consists of improvements on the invention described in Specification No. 17,986, A.D. 1900. In the apparatus described in the said Specification, the films are contained in a kind of drawer, by the first withdrawal of which from the outer casing a film from the back of the pack is retained in the outer casing, by the first return it is forced forward into the exposure frame, and by the second withdrawal and return after exposure the film is returned to the front of the pack. In the present invention, when the drawer or magazine D, Figs. 1 and 2, is pulled out, a peg f<7> on the lever F catches in a hole in the back film, and retains it ; when the drawer is drawn full out and then returned, the film is pressed forward into the focal plane. The drawer D on its return pushes back the pawl H, and turns the ratchet cam G into such a position that the oscillating lever F pivoted at f is moved into its central position. In this position, a pivoted angle plate L is pressed forward by a spring into notches f on the transverse arms of the lever F, and thereby bends inward the top of the exposed film, so that it passes inside the drawer on its next return, in front of the pack. In all other positions of the lever F the plate L is kept out of the notches, and consequently cannot press the edge of the film inward. The hexagonal shape of the cam G gives the necessary oscillatory movement to the lever F. Numbers are marked on the cam G to show the number of exposures.

Granted: 1902-02-20
Abstract: 4917. Hadfield, R. A., [Hibbard, H. D.]. March 8. Heating - furnaces for metals.-Relates to a method o f toughening manganese steel, and to furnaces for use therein, and for other purposes. The method consists in gradually beating articles of manganese steel to a high temperature, b y passing them through zones of increasing temperature, before plunging them into a cooling-bath in the ordinary way. The articles are kept from contact with products of combustion in the zones of lower temperature, but exposed to them in the hottest zones. Figs. 1 and 3 show a simple form of furnace heated by a fire at F, from which the gases pass across the end of the furnace chamber to the chimney C. The articles are inserted at a and withdrawn at a<1>; or they may be inserted at intermediate points. Removable partitions P, P may separate the zones of different temperature. Figs. 4 and 5 show a modified form of furnace with a travelling bed consisting of sections F supported on roller chains G. The gases from the fire at Fx pass across the end of the chamber, and are then conducted through a flue F<1> under the floor to the chimney. The sections F, with the goods upon them, are inserted at a and withdrawn at a', being pushed through by hydraulic apparatus R, or otherwise. They are transferred bodily to the cooling-tank T. S, S' are cranes for facilitating the operations. Each of the floor sections F is constructed, as shown in Fig. 9, of an openwork grid frame with removable sliding plates M at the top, on which sand is spread. The articles are preferably supported on firebricks r, resting on the ribs of the grid, so that the plates M may be withdrawn before immersing the grid and its charge in the cooling-tank. The doors at a and a<1> and the dividing-partitions P, P', P<2>, may be simultaneously raised by turning the shaft D' ; but the chain pulleys from which they are suspended are so mounted on the shaft that each may be turned independently to raise any door or partition separately. The furnaces described may be used for the treatment of armour plate and other kinds and forms of metal.
