Title: Process for the Manufacture of Varnishes by the Direct Solution of Gums without Previous Fusion.
Inventor: TIXIER AUGUSTE
Filed: 1903-08-06
Granted: 1904-09-06
Abstract: 17,135. Tixier, A., and Rambaud, L. Aug. 6. Varnishes.- Varnishes are obtained by dissolving a gum, such as Manilla and kauri gum, without fusion, in a solvent consisting mainly of terpineol. Spirit of turpentine is heated with dilute nitric acid at 60‹-70‹ C. until the liquid no longer precipitates a solution of kauri gum. The product is decanted, washed with dilute alkali, and distilled with steam. A pale liquid is obtained, consisting of unchanged spirit of turpentine, terpineol, and such dehydrated products of the latter as terpinolene, terpinene, dipentene, &c. If the action is conducted at 15‹-20‹ C., a crystallized terpine is obtained, which is washed in water and converted into terpineol by treatment with dilute sulphuric acid. In this process, the nitric acid may be replaced by dilute sulphuric or hydrochloric acid. This product, mixed with spirit of turpentine, benzine, or alcohol, is used to dissolve the gum. The solution is filtered, and is ready for use as a varnish. In the manufacture of fatty varnishes, the amount of oil, such as linseed oil, which can be added increases with its acidity, whether produced by a preliminary treatment of the oil or by the addition of a soluble fatty acid, such as oleic, margaric, or stearic acid.

Title: Improvements in Shuttle Changing Mechanisms for Looms.
Inventor: ZWICKY HEINRICH
Filed: 1904-02-27
Granted: 1905-01-12
Abstract: 4881. Zwicky, H. Feb. 27. Loom shuttle-changing mechanism.-When the shuttle thread breaks, the draw-bar 10, Fig. 2, is, by the usual mechanism, moved in the direction of the arrow, oscillating the elbow-lever 7, 6, Figs. 1 and 2, by means of the rod 8, and thus exposing an aperture 5 in the bar 4 of the shuttle-race. At the same time, a guide-pin or diverter 19 is moved into the shuttle-race, coming into the path of the shuttle, which is diverted into the opening 5. The arm 7 of the elbow-lever, on the forward swing of the lay, encounters pins 17 on a double-armed horizontally-pivoted lever mounted on the underside of a fixed plate 11, and oscillates this lever. An arm of the latter, carrying the pin 16, operates a carriage 13 carrying the pusher 14, which pushes the lowest shuttle 25 in the fixed magazine 12 between the spring-pressed bars 20, provided with inclined lips 23, and into the race. A fresh shuttle is thus placed in correct position for picking. The springs 21, 22, 24 return the parts to their initial position.

Title: A Valve Gear for Air Compressors and like Machines
Inventor: WILSON FREDERICK WILLIAM
Filed: 1904-02-29
Granted: 1905-01-12
Abstract: 4923. Wilson, F. W. Feb. 29. Pump valves and valve gear.-Relates to valves and valve-actuating arrangements for air - compressors, vacuum pumps, water pumps, &c. In the double-acting single-stage air-compressor shown in Fig. 1, lift valves V are arranged within a chambered piston valve operated by an eccentric set a little less than 90‹ in advance of the crank. A', A' are inlet passages, D the outlet passage. A pivoted lever and tappet rod are interposed between the valves V, so that, as one valve opens, it effects the closing of the other. J, J<2> indicate waterjackets. In the two-stage compressor shown in Fig. 3, and in other forms, the valves V<4> are double-seated, have consequently a lesser lift, and are closed by the action of gravity only. A single piston valve suffices for both compressing-cylinders ; it is provided with an enlarged portion K<8>, and its weight is counterbalanced by the resultant upward air pressure upon the cover H', which is equal to the excess of the final receiver pressure over that in an intercooler, not shown. In one form of single-acting two-stage air-compressor provided with similar valve arrangements, a trunk piston works in a single cylinder, the lower portion of the trunk being reduced in diameter to provide an annular space in which the second stage of the compression is effected. The invention is applicable to multi-stage compressors, and to compressors with horizontal cylinders. The Provisional Specification mentions the use of a link-motion with double eccentrics for operating the piston valve.

Filed: 1904-04-12
Granted: 1905-04-12
Abstract: 8376. Emmett, W. April 12. L o o m s, warptension regulating in ; stop-motions ; back-bearers.- Relates to means for relieving the tension caused by the back-rest on the warps, when the shuttle is improperly boxed or is trapped in the shed. The stop-rod tongue of a sateen &c. loom, being operated by one of these causes, acts on and pushes the frog B forwards, knocks the spring-handle from its detent, and at the same time, by means of the brake-rod extension D acting on an arm E of the shaft F of the back bearer or rest, lowers the top part H of the latter and slackens the warps. The part H of the back-rest is raised into contact with the warps by a lever J, Fig. 2, acted on by a spiral spring K, which is connected to the bracket P supporting the weight lever of the let-off motion, and is adjusted in position by a cross-pin N, winged nut N, and wire hook M' fitting in a slot in the lever J. The latter is limited in movement by the bracket R. In plain looms, the back-rest is oscillated by a curved arm Q, Fig. 4, acted on by an eccentric S in the usual way, an additional free arm R being used. The two arms are connected in the manner of a pair of tongs, by means of a spring T, which gives the necessary relief when the back-rest is lowered.
