Title: Improvements in Methods and Apparatus for Securing a Dustless Road Surface
Inventor: THWAITE BENJAMIN HOWARTH
Filed: 1906-11-26
Granted: 1907-09-12
Abstract: 26,818. Thwaite, B. H. Nov. 26. Liquids, distributing; road rollers.- A machine for spreading hot tar and pitch on roads as described in Specifications Nos. 13,551 and 22,434, A.D. 1906, comprises a vessel, shown in Fig. 3, consisting of an open tank A into which the tar and pitch, preliminarily heated, are fed at A', and a closed pressure-resisting tank B into which the mixture of tar and pitch is pumped from the tank A through a filter-box C by means of a pump D. The same or another pump forces air into the top of the tank B through a pipe F, and the air pressure forces the mixture of tar and pitch through a valve J to a distributing-pipe K by which it is sprayed. Further spraying may be effected by leading compressed air direct from the top of the tank B to the valve J by means of a pipe L, as shown in Fig. 6, the cone-shaped nozzle 8 increasing the spraying action. The pumps are fitted with ball valves and driven by chain gear from one of the axles. The mixture of tar and pitch is highly heated in both tanks by means of a flue G heated by a grate H. In order to produce a more effective binding of the road material by the tar and pitch, the road surface is preliminarily heated by a road roller shown in Fig. 5, which is drawn in front of the spraying- machine. The upper part of the roller is heated internally by afire basket 2, or by lamps hung from the axle, or by jets of petroleum &c. supplied through the hollow axle or otherwise. Sand, preliminarily heated, may be spread on the tar, as described in Specification No. 22,434, A.D. 1906. In some cases, a small proportion of water may be added to the tar, or tar and pitch, to facilitate spraying, where dehydration is not essential.

Title: Manufacture of Vat Dyestuffs
Inventor: IMRAY OLIVER
Filed: 1907-02-04
Granted: 1908-02-04
Abstract: 2769. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Feb. 4. Dyes, artificial.-Dye-stuffs giving red-violet tints in a hydrosulphite vat are obtained by heating certain arylthioglycollic acids, unsubstituted in one o-position, preferably those substituted in the p-position or the other o-position by methyl or halogen, with sulphuric acid monohydrate or concentrated sulphuric acid, until the green colouration and formation of the dye-stuff no longer increase. Agents may be added which aid condensation and hinder sulphonation. The reaction may be modified by allowing the arylthioglycollic acid and sulphuric acid to stand together in the cold, but for a much longer period. Those arylthioglycollic acids are most suitable which are sulphonated with the greatest difficulty, such as those derived from o-toluidine, p-toluidine, pchloraniline, p-bromaniline, o.chloraniline, dichloranilines, chlortoluidines, m-xylidine, chlor-pxylidine, and #.cumidine.

Granted: 1910-07-21
Abstract: 17,432. Morris, H. July 27. Regulating and control-transmitting gear for winding and paying - out apparatus. - The driving clutch used in connexion with the handle, or hand - wheel, or a member of the change-speed gear, of a winch provided with band and automatic centrifugal brakes of the type described in Specification 20,390/08, is interlocked with the self-sustaining band brake so that the handle remains stationary when the brake is released for rapid lowering. Figs. 2 and 3 show a winch in which the handle D is loosely mounted on the first motion shaft B and is connected to the sliding sleeve E by a claw clutch. The sleeve is moved axially to disengage the clutch during the initial rotary movement of the lever F, by means of projecting pins on a sliding sleeve E<3> having camshaped ends which are engaged by rollers F<2> mounted in a casing fixed to the boss of the lever. Further rotation of the lever operates a weighted crank arm G<4> to release the selfsustaining band brake G<1>. The lever is restored to its original position when released, by a weighted arm H connected to the casing on the lever by a cord H'. Figs. 7 and 8 show a winch in which a member of the changespeed gear is interlocked with the brake. The movable clutch member K of the changespeed gear is operated independently by two linkages, one being an ordinary set of changespeed levers partly shown at N, and the other, a lever M having cam-shaped edges engaging the forked end of the brake-operating lever O. The initial movement of the lever moves the member K to its mid-position, and the further movement raises the weighted arm O<6> to release the brake. A pivoted tumbler M<1> on the lever M prevents accidental disengagement of the clutch member K when either speed is in gear, ensures the full travel of the member when operated by the change-speed levers, and automatically re - sets the particular speed gear previously in operation, when the brake lever is released. Driving-gear for winding and paying - out apparatus. - A ratchet device is used on the handle or first motion shaft of the winch to form a positive lowering device for the unloaded chain or rope. The pawl J controlled by the spring J<1>, Fig. 2, rotates the driving-sleeve E when the handle is declutched therefrom and rotated in the direction for lowering. The selfsustaining band brake is released before this operation in performed. In the winch shown in Fig. 8, the pawl is carried by a member R<1> on the hand-wheel shaft and engages ratchet teeth on a member L<1> of the change-speed gear. Winch and like handles.-The winch handle D, Fig. 2, is slotted so that its effective length can be varied. A clamping - screw D<2> passes through the slot, while the lower end of the handle is provided with sliding bearings D' to transmit the driving force in all positions.
