102 THE COLLIERY GUARDIAN. July 10, 1914. adapted to effect engagement with the drawbar hook of said vehicle that the same may not become detached and withdrawn during the progress of the vehicle, but, further, may be disengaged with facility. The invention consists of an improved locking member or pair of locking members secured to or in the top end or head of said pin. The head is provided in the known manner with a projecting arm for attachment to the animal draft gear. The pin member is cylindrical (with one end coned) to p^ss through the draw- bar eye, whilst its other and top end has an arm for con- nection to the animal draft gear, and a gravity or spring- held pivoted catch member adapted to pass around the draw- bar eye and take thereunder. The catch member is extended above or is offset from its pivot so that it may be manually released to permit the withdrawal of the pin member from the drawbar. Fig. 1 is a perspective view, showing the limber pin in engagement with the drawbar of a truck; fig. 2 is a sectional side elevation of fig. 1; fig. 3 is a transverse sectional elevation of fig. 1; fig. 4 depicts a modified form of pin, having one catch member only, which is offset.

Smidth and Company, of 33, Vestergade, Copenhagen, Denmark.— Comprises a form of drive for the channel, such that the shocks produced by the reciprocating movements of the channel are absorbed in a perfectly resilient manner, whereby wear on the bearings and on the channel is largely reduced, fig. 1 being a side elevation of the channel and its driving device, and fig. 2 a detail showing the way in which the channel is hung. In the position illustrated in fig. 1, in which the crank c presents the greatest velocity in the longitudinal direction of the channel, it imparts to the latter its maximum speed. Under the influence of this speed given to it by the crank the channel oscillates beyond the point to which it would oscillate if the connecting rod were of the usual rigid type, as far as the point f. This oscilla- tion takes place without a continuous drive through the crank c, the point of attachment of which to the driving rod has a smaller linear displacement in the direction of the oscillation of the channel than that moved through by the channel under the influence of its momentum after the crank has passed its highest point. The result is that under \ Fig.l. \ \ \ ----- Fiji —i r Vw k i Xm* "W the influence of the extended spring k, when the position of the crank c illustrated in fig. 1 has been passed, the rod d, n collapses. In the meantime, the channel continues its displacement to the point /, whereby the material in the channel is conveyed towards the end i as the channel is moved relatively to the material owing to the inertia of the latter by the driving action. When the extreme point f is reached, the channel swings back freely, and then effects a fresh forward oscillation, during which an impulse is imparted to it by the action of the crank c through the con- necting rods d n, which in their extended position, that is to say, when they are extended in a straight line, form a rigid connection between the crank and the channel. The end of each driving period of the crank is reached when the crank assumes the vertical position shown in fig. 1. The shocks which might be imparted to the channel and its bearing at the commencement of each forward movement by the momentum of the moving crank c, hub o, and rod d, n, are resiliently absorbed by the action of the spring k, so that the flywheel or driving pulley I resiliently connected with the hub o acts without shock upon the channel in the position of the crank c, in which the impulse displacing the channel is given to it. (Three claims.) 20460 (1913).—Improvements in and relating to Binding and Impregnating Materials made from Waste Sulphite Lye. E. Pollacsek, of Villa Pinelli, San Bartholomeo, Spezia, Italy.—According to this invention, the excess of lime added to the lye is removed during the evaporation by means of rock oil distillate deprived of benzine. The con- centration of the lye, which has become a thick fluid, is then continued, and more heavy oil is added while the lye is in a hot condition, whereupon the whole mass is allowed to cool. The mass is now mixed again with heavy oil, lime paste is added, and the whole boiled. For forming coal briquettes from coal dust, for each 100 parts of the material, 4-5 parts of solid main binding substance, 5 parts of crude oil deprived of benzine, and 2 parts of burnt lime or a correspondingly greater quantity of hydrate of lime are used. The addition of water is calculated so that the binding mixture should have a density of 32-35 degs. BaumA (Two claims.) 20516 (1913). Improvements in Stops for Regulating the Passage of Colliery Tubs and the like. — T. Gray, St. David’s, Denbeath, Fifeshire, and J. Neil, 20, Queen-street, Wolverhampton.—Delates to improvements in or connected with apparatus for controlling and regulating the passage of trams, wagons, tubs, or other rolling stock, hereinafter referred to as tubs, at a position which they have a tendency to pass under the action of some external force, such, for example, as gravity or impulse, the apparatus being par- ticularly applicable for controlling and regulating the pas- sage of colliery tubs at positions such as pitheads, screening or loading banks, and the like. Apparatus according to this invention comprises improvements in construction involving provision of a cradle upon which a sprocket wheel, or more than one, is axially carried, and controlled by means of a locking bolt disposed in the bed of the cradle at right angles to the axis of the sprocket wheel, this bolt, for the purpose of operation, being adapted to be moved longi- FlG f/g 3. n I fTjjCZ tudinally, and having a locking head so arranged that the thrust to which it is subjected is at right angles to the length of the bolt. Fig. 1 is a side elevation partly in sec- tion ; fig. 2 is a plan ; and fig. 3 is an end elevation. (Four claims.) 22006 (1913). Improvements in Detachable Haulage Hooks or Couplings. P. Gill, of Ashleigh, Lunn-road, Cud- worth, and R. W. Spencer, of High-street, Grimethorpe, Yorkshire.—Relates to a type of appliance in which a link or coupling of a corve is secured through a hole at one end, and a link or coupling of another corve or haulage rope is attached and secured at the other end by means of a pivoted slip hook or jaw. The object is so to form and construct the appliance that it shall have no protruding, parts or angles which could catch on any of the projections on the railway or tramway, and to this end it is provided with a concealed spring-pressed locking pin, which automatically engages with and locks the free end of the pivoted hook when pressed home, and which can be readily withdrawn by hand. The accompanying drawing is a side elevation partly in section of the improved coupling, with the pivoted hook shown opening downwards; fig. 2 is a plan view of same; fig. 3 is a side elevation partly in section of part of a modified form of hook adapted for vertical haulage; fig. 4 is a plan view of same.
