824 THE COLLIERY GUARDIAN. April 27, 1917. THE FREIGHT MARKET. The outward freight market has shown considerable activity during the week, especially at Bristol Channel ports. On the north-east coast there have been fairly large arrivals of tonnage, but, unfortunately from the point of view of the private shipper, most of the vessels have been previously requisitioned, and have merely come to the district to load supplies of coals and coke on official account, or are on time-charter. Such steamers, whilst, of course, stimulating the work of the collieries, do not help the open freight market to any extent. However, even on the north-east coast, supplies of “ free ” tonnage have been rather larger, and more fixtures have been arranged. Most of the vessels taken up have been for French Atlantic ports with coke, but a few ships have been arranged for for the carriage of cargoes to greater distances. Barcelona, for example, has been chartered for at the very high rate of 165s., a rate which shippers would be prepared to repeat several times if the vessels were offered. West Italy has been done at the old limitation rate of 64s. 6d. for a British boat. Coasting figures are rather higher on the week, London being listed at from 20s. 6d. to 21s. from the Tyne. For Scandinavian directions., from 150 kr. to 160 kr. to Copenhagen is representative. At South Wales, business is really “booming” by comparison with recent lean weeks. So far as volume of fixtures is concerned, the French ports have pride of place, many small vessels having been engaged for near French destinations. Barcelona has been done from Cardiff at from 160s. to 162s. 6d., as against 162s. 6d. a week ago. Gibraltar, on the contrary, has been done at 5s. advance on the week, as has also Dakar. Bilbao is steady. Several vessels have been fixed for Valencia at. 160s. It is evident from the greater volume of outward chartering now being done that the recent increments to the rates offered for neutral tonnage plying between this country and French and Italian ports are having their effect in attracting cargo space, although even yet the amount of tonnage on offer leaves very much to be desired. Homewards, there is no change in the River Plate rates, these remaining at 135s. from up-river and 130s. from down-river ports to the United Kingdom, at which figures business is very slow. At the United States, there has been another advance in Virginian coal freights for the Plate, these having gone up to 107s. 6d. to the lower ports. spending members On net form of charter, neutrals can still obtain 200s. from e, e at each end of Northern Range to France. On account of the Wheat Committee, the Northern Range to French Atlantic is 5s. dearer, being listed at 42s. 6d., with the Gulf indicating 2s. 6d. more, an increase of from 2s. 6d. to 5s., to the same destination. At the Far East, Saigon-Haiphong to Marseilles with rice has fallen 30s., being now mentioned at 320s. For jute from Calcutta to Genoa, the rate is unaltered, at 280s. From Madras Coast to Marseilles with kernels, there is a fair demand for tonnage, and 500s. is offered, an increase of 60s. on the week. Kurrachee to to United Kingdom is steady, at 240s.; but Bombay to the same destination is 20s. down, at 280s. Tyne to Algiers, 4,500, 53s: 6d.; Barcelona, 3,300, 165s.

C. R. W. Baldwin, 29, Cymmer-road, Caerau, Bridgend. — This invention relates to safety catch gear or safety retaining mechanism for mine cages, lifts, and like structures. In safety gear of the type described, hook-like members are employed, each provided with a’hook at one end, and having a spring attached to the other end, said members being pivoted to the mine cage or the like at a point intermediate of the ends, a flexible connection being pro- vided between the lower part of the winding cable and the hooked ends of said hook-like members. Novelty is not claimed, for any of these features per se. The invention is illustrated in the accompanying drawings, which repre- sent its application to coal mining. Fig. 1 is a side sec- tional elevation of one cage of the single-deck type and part of the shaft, with the improved gear or mechanism fitted, and in the inoperative position; fig. 2 is a corre- sponding sectional plan, with the two cages about to pass one another. The same letters of reference are used throughout to designate the same parts, and of those parts already mentioned, referring generally to the drawings, a denotes the cage, b the shaft, c the winding rope, d, d the guides of the flexible or rope class, e, e the movably- mounted hook-like members , f, f the stationary comple- mentary members, g, g the means for retaining the hook- like members e, e inoperative, and h, h the means for ren- dering them operative, while i,,i denote the shoes co-acting with the guides d, d, and j, j the taut chains, and k the slack chain connecting the cage a, through the medium of a triangular connecting piece, to the winding rope c. With the exception of the members e, e, the members /, f, the means g, g, and the means h, h, which constitute this invention, all the parts mentioned are of ordinary con- struction and arrangement, though the guide shoes i, i are situated on the cage a as shown so as not to foul the hook-like members e, e. The hook-like members e, e are four in number, a pair being situated at each side of the cage a, and each one of a pair being centred upon the bottom of thev cage a towards the end thereof, so that the hooked extremity I is in proximity to the stationary mem- bers /, /, with one of which it is designed to engage in use. The corre- the cage a are mounted on an axle m arranged at the underside of the bot- tom of the cage, and supported at ' the ends by straps n, n, fixed to the sides of the cage a. The axle m is preferably of square. cross section, except at its extreme ends, which are of circular section, and on such portions the hook - like members e, e are turnably mounted. In order to secure the mem- bers e, e upon the axle m, and preserve their proper relative position with refer- ence to the guides d, d, suitable means are provided, such as collars o and p fast- ened to the axle m at each side of the i -"Il z \ a > e TM 6 member e. It will be noted the axle m is fixed, and to protect .it a housing q is applied, and secured to the bottom of the cage a. Each hook-like member e is maintained in an uplifted position, or out of engagement with the mem- bers f, f, by the means g, consisting of a wire rope attached at one end to the top link of the hooked extremity I, and at the other eiid to the slack cage chains k. This is accom- plished against the influence of the means h for effecting the lowering or engaging position, which consists of a helical spring secured to and between the tail r of the member e and the contiguous portion of the cage a. To determine the fall of the member e, a stop 5 is fixed to the bottom of the cage a. The stationary members /, / are assembled in two opposing sets transversely of the shaft b, one at each end of cages a, a. They are constituted by bars located at convenient intervals down the shaft, the distance between them being preferably such that the cage a cannot acquire too great an impetus in the event of the winding rope c breaking before being arrested. An appro- priate spacing appears to be 6 ft. or thereabouts. The transverse section of the members f, f, of course, agrees with the contour of the hooked portions I, I of the mem- bers e, e, and their ends are firmly embedded in the wall of the shaft b. The operation of the several parts is briefly summarised as follows :—The drawings show the gear or mechanism in the inoperative position, the ropes g, g holding up the members e, e by reason of their con- nection with the chain k, and the springs h, h tending to depress the members e, e. However, on the winding rope c fracturing, the ropes g, g are immediately slackened, whereupon the hook-like members e, e are freed and low- ered under the influence of the springs h, h into the path of the fixed members f, f, and into the position determined by the stops s, s, and in due time, as the cage a falls, the portions I, I of the members e, e engage a pair of the opposing stationary members /, f, and thus the cage a is stopped and sustained. In arresting the cage a, the springs h, h serve to damp or buffer the engagement of the hook- like members e, e and the stationary members f, f, and by spacing the latter not too greatly, the acceleration of the cage a is minimised, whereby the detrimental effects of jerking consequent on sudden stopping are materially obviated. The hook-like members e,. e, and their adjuncts, are restored to the original positions on the necessary repairs being performed. (Two claims.) 104560. A Watering Tank and Spray Producer Parti- cularly far Use in Coal Mines. L. Phillips, 37, Hopkins- terrace, Abercregan, Cymmer, Port Talbot, South Wales. -^-This invention relates to a watering tank and spray pro- ducer which can be attached to the ropes and worked with the journey, and can be worked with a horse where the ropes are not working. There is a round brush and a trough at each end of the tank. The brush spins round by means of a belting on the wheel of the tank. The troughs are supplied by means of a pipe running under the tank, and has a double connection valve. It can be worked both ends or single, and the water is sprayed to any height required underground. It will water the full trams as they are travelling, and the front part of the tank is capable of watering the roads 4 or 5 yds. in front of the journey, and it will- make a very small spray of water. Fig. f is a part section and elevation of the improved watering tank, which shows the end view of the spindle with the brushes and protection to same; fig. 2 is a plan of the watering tank with a view of the chain, belt, or rope attached to the driving wheel. The corresponding letters are employed throughout these illus- trations to indicate the corresponding parts. A square or circular tank a is adjustably mounted on a bogie or ordinary tram carriage frame suited to the gauge of the tram- way or railway adapted at the colliery. The tank is reduced in width at the bottom for the purpose of enabling the level of the water to come to the lowest point possible. An open pipe b is inserted into the bot- tom of the tank a with a regulating or control valve c; along the out- side of the bottom of the tank is a pipe h h, through which the water is conveyed into the troughs d d at each end of the tank. A spindle or shaft g g revolves in the trough with bearings at each end ; along the shaft or spindle are fixed cane brushes i i. The power to revolve the spindle or shaft is conveyed by a chain, belt, or rope e attached to the flange on the inside of the tram wheel, and around the small wheel or pulley fixed to the shaft or spindle g. A hinged grid for protection of the revolving spindle is shown at / f. The valve c is a slotted piston which works within a cylinder, and is attached to the bottom of the tank. The slotted portion k of the piston, when opposite the open pipe b from the tank a, allows the water to flow into both pipes h h. When the slotted part is turned opposite one of the pipes h h, then that pipe would be in operation, and the watering done from that end of the tank. If it is necessary to close the valve, then the slotted portion would be downwards, and is the reverse to when open. The valve may be adjusted at j either to do the watering or spraying at both ends simultaneously, singly, or alternatively. (Two claims.) 102151. Improvements in Driving Gear or Operating Arrangements for Compressors or Air Pumps. J. Gralla, 11, Wattstrasse, Siemensstadt, near Berlin.—This inven- tion has reference to driving gear or operating arrange- ments for compressors or air pumps. The operation of pumps for air and gases requires a certain amount of energy, which increases with the degree of compression or rarefac- tion. When the compression or rarefaction of ’the medium in the reservoir or air vessel has reached a certain point, the amount of energy which is necessary to bring the pres- sure* or vacuum in the reservoir to the required degree is extremely high. In the case of pumps driven by mechani- cal force, the difficulty will easily be overcome, but in compressors of known types driven by hand it requires hard work to bring the compression to the required degree. The present invention may, however, also be of great advantage as an auxiliary device on pumps or compressors normally driven by mechanical force, and may be especially useful in those cases in which it is required to use the Jrl iiiiij i| i" i jz _1iiiL._lL_ Ct J>v pump at places removed from the driving motor. In such cases the additional hand-driving gear or operating arrange- ment, according to the invention, may be used to actuate the compressor. The said invention has for its main object to provide compressors or pumps of all kinds, especi- ally those of a two-stage character driven by hand, with an improved hand crank driving gear whereby, with an increasing degree of compression or rarefaction in the reservoir, the power applied to the compressor or pump by the operator will increase in the same ratio. For this pur- pose the improved crank lever or handle is constructed in such a way that the arm or leverage will be increased and diminished as the degree of compression or rarefaction requires, and hence the turning moment will be varied automatically as required. The apparatus has the further advantage that it is simple in action, and of comparatively small weight, so that the pump may be used on a large scale, for instance, for inflating automobile tyres, charg-
