The present invention relates'to an improvement-in or relating toa device for weighing the load of a railway coach or wagon consisting generally in making use of the established parallel r'ails by providing a resting frame extending between the said rails in such manner that the loads acting on each side of the Wheels after-balancing by a rectangular receiving frame are transmitted to two main levers extending towards the centre of the device where the adjacent ends of the leversoverlap and are pivotally connected together and Where the loads are thus concentrated into a single load.
According to the otherfeature of the inventio'n'the action of the two main levers is controlled under the action of a balancing spring, and the rectangular receiving framev p is limited in action in a very small degree by regulating wedges, so that the device may be of considerablyreduced size, while despite the small size it may be employed for weighing such heavy loads as loaded railway cars or wagons. V p V Heretofore it has been necessary for such weighing purposes to build an underground chamber for arranging a hoisting machine 7 and a weighing machine. The present invention, instead of such arrangement, provides instead a slmplehandy device that can be easily placed in position, which will not obstruct the railway track against the passage of railway carsor wagons and by which a veryaccurate weighing may be effected iirspite of the device being of such comparatively small dimensions.
- The accompanying drawings illustrate one cnample of carryingout the present invention,inwhich: Fig. 1 is anelevation; Fig. 2 is a central sectional elevation; Figure 3"is a plan thereof; and Figures l; 5 and6 are sections taken on lines 1 -1, 11- -11 and III'I'II of Fig. 1
- respectlvely.
Referring to the drawings, A A are the two parallel rails of alrail-way track, formed I with bases a, a; B; B are the two main beams of the main frame connected to each other by the intervening bars I), b respectively connected at their end portions to the respective adjacent-end portions of the respective beams B, B to complete'theanain frame structure. The main beams B, B are so'formed that in use the lower faces of their respectiveend portions Will reston, and be supported b the said bases a, a of the respective rails i A of a-railway track as illustrated; C represents the car or wagon wheels, each formed with the usual guide flange or projecting rim 0; Dis a load supporting frame of rectangular form, the two ends cl, (Z of which are re spectively disposed adjacent the respective rails A, A in the path of travel of the rims c of the Wheels 0 respectively traversingthe respective rails A; Each said end def said frame D is of'inverted'V shape and provided in the centre with a recess to receive the proecting rims of the Wheels; E, Eare'the'two 'main levers, each pivoted or fulcrumed at e on the corresponding connecting bar I) of the main frame, and have ends to support the abutting ends d, d, r i. a a
The inner'ends of the main levers Eoverlap and are pivotally connected together by knife edge pivotr'pins 2 and have their outer ends disposed beneath the respective ends (Z of the supporting framel). Knifejedge sup ports or fulcrums lmounted on or'supp-ortwith the weight or thrust exerted onthe fill crum 1 on the one hand as opposed by the weight ormechanism on the other hand..-
are provided as usual for cooperation with m ght occur 111' weighing.
each other and with the scale arm H for 'indicating the weight of a particular loaded car or wagon. The lever F is connected intermediate its points of connection with the lever G andthe pivot pin 2, to one or both of the main frame members'B for swinging movement in a vertical plane by means of a ring or rings 1- embracin knife edge'pivotsrespectively extending through said lever and between said members B. J is a balancing spring, secured at one end to apart of the machine frame and at the I disposed between rails A, A at any desired place where the weighing is to be performed. The two ends ofv the resting frame rest stably on the bases a, a of the rails. Corre-v sponding to theshape of therails and of the wheels the bolts L are rotated as required, causing the wedges K to advance and retreat, whereby the. height I of the main 7 frame isadjusted, the ends (Z of the supportingframe D are slightly projected upward of the rails, the wheels are induced. to rotate and by displacing themselves, to ride on the ends (Z, and thus the wheels may be detached from the rails.
The weights W, 10 areincreased or re duced, then the load carried by the front part of the wagon, or by the axle of the wheel at the back of the wagon is transmitted through the two wheels onto the supporting frame I), when the said load acts, through the first, second, third, and fourth levers, E, F, G and H, upon the weights W, 10, so that the load may be weighted. Simultaneously the balancing spring J acts at the central part where the main levers E are connected together, so as to pull them up through the medium of-the lever 8. By this means the accuracy in weighing is easily obtained, and also the device according to the invent-ion may be so reducedin size that it may suitably be accommodated betweenthe ra'ilsat any desired places. i
i It is to be noted that the means for mounting the main frame between the rails, must be ofthe same width as the span between the rails, and also must not project considerably from the tramp surface of the rail.. The main frame, being supported on the inclined surfaces ofthe bases of the rail, is subjected to. two opposite forces. acting toward the centre at the ends of the resting frame, and under this condition, the vlatter is kept in a more stable position. r
It should be appreciated that the means consisting of the two main levers, which press the wheel upwards through the rectangular supporting frame on which the projecting rims of the wheel are resting, is
adapted for such purposes as follows: The leads acting upon the two wheels carried by an axle on each side are first received by the rectangular supporting frame, thence transmitted through the main levers and concentrated at the, point of connection of said main levers E, and as a loadso cons centrated, it may further be transmitted to the second, third, and fourth levers, in the order. By this means also it is assured that,
th-eweighing. device according to the invention may be prevented from receiving unbalanced weights which break its accuracy,-
since the load, after equalizedby the rectangular supporting frame is transmitted to the weigh a considerable load, without in'accu racy.
It may also be understood that the wedges are formaking the scope within which the various levers act, as smallas possible, when the wheel is pressed up. It is suficient for such purpose if the abutting ends are raised I up slightly over the height of the rail, while this is adjustably done under the compensat ing action due to the balancing spring.
