Title: Process of Tanning Hides
Inventor: ROACH WILLIAM GRANT
Filed: 1906-12-24
Granted: 1907-05-16
Abstract: 29,368. Roach, W. G., and Roach, A. C. Dec. 24. Tanning; hides and skins, tanned, treating.- Relates to the metallic tanning of hides, and consists in introducing into the hides, in an inactive chemical state, compounds adapted to produce a tanning-substance by inter-action, and then establishing a condition under which such reaction can take place. The hides are submitted first to the action of a metallic acid bath, preferably chromic acid, which may also contain alum and salt and sulphuric and hydrochloric acids. The hides are removed from the bath, slicked, set out, and hung up to dry until about three-quarters of the moisture has evaporated. The hides are next painted on both sides with a reducing-substance, preferably glucose, which does not act on the chromic acid until the temperature is raised, and are - stacked to allow the glucose to soak into them. Other reduciug-agents, either inorganic or organic such as glycerin, may be used. After impregnating with the reducing-substance, the reaction between the two substances is caused to take place by preferably submitting the treated hides to the action of steam. In place of the steam, the reduction may be effected by immersing the hides in a hot grease bath. For the production of sole-leather, a bath consisting of stearic acid, carnauba wax, vaseline, and bees-wax is used. If glycerin is used as the reducing-agent, the reduction is caused by merely stacking the hides. For greased leather for harness, the leather is stuffed in the grease bath.

Patent GB-190709670-A (GB)
Title: Improvements in or relating to Lasting Machines.
Inventor: ROBERTS FRANCIS WILLIAM
Filed: 1907-04-25
Granted: 1908-05-25
Abstract: 9670. Roberts, F. W., and Ward, A. April 25. Lasting. -Relates to lasting- machines in which. the pincer-bar is given a combined lateral and twisting or rolling motion of a yielding nature, in addition to the usual spring control for the updraw, and consists in the provision of a single yielding-controlled operating means for actuating the pincer-bar. The pincer-bar a, Figs. 1 and 4, is suspended as usual by a ball joint a<1>, and passes through a cross-head c, which comprises tubular sleeves c<1>, c<2> arranged at right angles to each other. The sleeves c<2> are mounted in bearings in a two-part yoke d, d<1>, adapted to be reciprocated from any suitable part of the machine to effect the lateral throw of the pincers. They are, surrounded by bushes f formed on brackets f<1>, to which is secured a rack g meshing with teeth a<2> formed on the pincer-bar. A rod or spindle e', adapted to be reciprocated by a rod e, passes through the sleeves c<2>, and carries a pin e', which is engaged by the forked end i<1> of a rocking piece i. This normally bears against the lower side of a lever h, which rests on pins h<1> projecting from the cross-head c and is acted upon by an adjustable spring located in a hollow nut c'. When the spindle e<1> is reciprocated, the pin e<2> rocks the piece i, which tilts one end of the lever h against the pressure of its spring. This causes the other end of the lever to bear on its pin, and to move the cross-head c and consequently the pincer-bar a to one side and across the rack g. The twisting or rolling motion thus produced is consequently always of a yielding nature. The machine is also provided with an improved arrangement of grippers. The pincer-bar carries a sleeve k provided with extension rods k<1>, which pass through the crosshead c and terminate in a connecting-plate k <3> beneath a stop a<3> on the bar a. The movable jaw b<1> of the grippers is carried by a rod l carrying a collar l<2>, which seats against the plate k<3>. The jaw b<1> is thus caused to rise and fall with the rods k<1>, while the pincer-bar and grippers are always free to rotate. An embracing plate b<2> secured to the bar a serves to keep the jaws b, b<1> of the grippers in alinement.

Title: Improved Process for Extracting Glue from Mineral Dressed Leather.
Inventor: WEISS ALBERT RUDOLF
Filed: 1907-08-23
Granted: 1907-12-19
Abstract: 19,019. Weiss, A. R. Aug. 23. Hides and skins, tanned or tawed, treating.- Glue is extracted from mineral-dressed leather, for example chrome-tanned leather, by treatment with hydroxides or salts, or with both, of the light metals, such as alkali or earth alkali, and boiling down. Treatment with alkali, for example lime or soda, at a suitable temperature partly detans or dechromes the leather so that part of the glue may be extracted by simply boiling the leather with water, the quantity being increased if the treatment with the base is effected at temperatures up to 100 or 125‹ C. At the higher temperature, salts, particularly phosphates, of alkalis or earth alkalis may be used instead of, or following treatment for, the caustic bodies themselves. In examples, the mineral-dressed or chrome-tanned leather is treated for various periods and at various temperatures with calcium, barium, strontium, potassium, or sodium hydroxide followed by washing and boiling down as usual. In other examples, the addition of a lye of earth alkali or calcium monophosphate or other calcium phosphate is followed by boiling down the whole mass. Ground bones, raw or treated with acid, may be used as the salt.

Title: Improvements in Apparatus for Regulating the Flow of Liquids
Inventor: HODGSON JOHN LAWRENCE
Filed: 1907-09-17
Granted: 1908-09-17
Abstract: 20,616. Hodgson, J. L. Sept. 17. Liquid levels, regulating. - In apparatus for measuring a stream of liquid, comprising a chamber R, Fig. 1, to which the liquid, under variable head, is supplied by a pipe H, and an adjustable weir A or orifice O in the chamber R, a combination of floats F and weights W, W operating a valve V or C is provided, the object of which is to prevent the liquid from rising above a predetermined level. The valve, float, and weights are mounted on a frame turning about a pivot B. Some of the weights may be replaced by equivalent floats E, Fig. 3, arranged to produce the same couple about the shaft B. The weights are so disposed, and the shape of the float is so designed that, when the liquid is at the predetermined level, the moving parts are in neutral equilibrium, and, if the level tends to rise further, the consequent unbalanced increment of buoyancy of the float causes the moving parts to move rapidly through the whole range of their movements to close the valve. When, subsequently, the level tends to fall below the predetermined level, the reduction of buoyancy of the float permits the weights to move the valve rapidly to its extreme open position. To damp down oscillations in the event of large variations of head, a chamber E', Fig. 3, dipping in the liquid and provided with an orifice P, is attached to the float or connected to the frame carrying the float.

Title: Improvements in or relating to Electric Motor Controlling Apparatus.
Inventor: CHAUDOIR EUGENE
Filed: 1907-10-30
Granted: 1908-10-29
Abstract: 24,002. Chaudoir, E. Oct. 30. Switches.-Resistance is cut out of a motor circuit by a switch which is operated through suitable gearing thrown in by the tightening of one side of a belt driven by the motor. The arm of the resistance switch shown in Fig. 1 is connected by a slotted link B to a crank C on the same shaft as a friction wheel D. The belt F passes round the motordriven pulley I and the idler K. When the motor starts, the upper side of the belt tightens and throws the friction wheel E, which is on a slotted bearing, into engagement with the wheel D. The crank C is then driven to raise the resistance switch arm until it reaches the hold-on coil L, and then the crank continues to revolve without moving the switch arm. The friction wheel E may be arranged to move into position by rolling along the belt, instead of being raised as in Fig. 1, and the arm may be operated by a rack, or by a toothed quadrant. An open cross-head B<2>, Fig. 4, may be connected to the resistance switch, and is raised by a crank C, which works on a threaded spindle so that it is free except when the motor is not running. The crank spindle is driven by friction gearing from the belt, and may be allowed to revolve in the cross-head when the switch is fully raised, if a hold-on coil is used. Or, the crank may be held by a stop L<1> and the friction gear permitted to slip. When the motor has to run in both directions, two sets of the apparatus or two sets of wheels, one for each side of the belt, operating the same crank may be used. The crosshead may be held up by pawls operated by the friction wheels. In the modification shown in Fig. 7, one of the rollers E is raised into engagement with the internally and externally grooved friction wheel D. The links H are also moved to keep the frictional rack B<1> against its driving- wheel C<2>. Another modification shown in Fig. 8 has a crank K<1> and lever C carrying a pawl C' which engages a ratchet-wheel D. A wheel B' on the same shaft as the ratchet-wheel winds up a cord or chain attached to the rheostat arm ; or, a rack and pinion may be used. The rollers E, E' are carried by a cam H pivoted at H<1>, and, when one of them is raised, the cam H is moved to permit the pawl C<1> to drop into engagement with the ratchetwheel. A retaining-pawl L prevents the wheel from slipping back, and is disengaged by a pin H<2> on the cam H. In each of the modifications, the contact-arms may be in duplicate or triplicate for two- or three-phase circuits.
