Railway companies are always greatly con cerned with the keeping clean of their ballast, which is the chief condition for the;

proper upkeep of railroad traoks.'- V a lVhen it is desired to have constantly clea ballast without being compelled to renew it completely which would be very costly, the old ballast is sifted so as to remove the earthy material and the'minute particles produced by the crushing of the stones. Thus only those stones are retained the size of which is above that of the screen mesh chosen. The volume ofballast is completed by adding a certain amount of fresh ballast. y 7 15 This manner of regenerating the ballast is much cheaper than its simple replacement and consequently it is much usednowadays. It used to be efl'ected entirely by hand, but latelyit has been executed mechanically by machines having a very large output. The sifting however is subject to a very hinder some trouble which consists in the necessity of removing the waste falling on the sides of the track during the operation of ballastregeneration. Heretofore such waste had to be loaded on a service train passing in front of the yard onthe; moments available between the passages of the regulartrainsythe loading of the waste being effected with shovels. This work is lengthy and requires the formation of a specialservice train the efiiciency of which is very small and which moreover may be a cause of disturbance for the ordinary trains. v l i The mechanical sifting methods which increase the speed of'progress of the yards along the railroad track have simultaneously increased the volume of waste to be removed efiiciency ballastremoving vehicle provided or not with sifting means.

v Fig. 4 is an end View thereof, 7 Figs.) 5 and 6 are respectively a side view and an end view ofa modification of said means. Referring to Figs. 1 and 2, the waste produced by the sifting operation are raised by the conveyor 64 from. the ballast removing vehicle and fall into a hopper 7) carried by the frame d supported by the truck 0. To the longitudinal sidesof the truck are secured two rails ee on which a carriage f carryinga hopper g is adapted to run. This carriage at f-is self propelling through the agency of a motor k and of suitable transmissions. It may run over the rails 'e-e not only on the truck a but also on the adjacent truck 2 and the following trucks which are all provided with the same rail arrangement along their sides, the rails forming a continuous track from one end of the train tothe other owing to the interposition of a pivotedlink arrange- The arrangement comprising the hoppers, carriages and rails therefor is adapted to pass inside the gauge y of goods-carriage for the track along which the trucks move.

The-workingis as follows; v

The hopper I) being full, its bottom Z is opened and the contents fall into the hopper g. The bottom Zis then closed again, the carriage f is caused to start so as to'bring the hopper g to point 9 for instance onthe 01- 9 lowing truck 2. There its bottom m is opened and its contents fall into the ballast-truck 2 after which the hopper g is returned with its carriage f underneath the hopper b which has been filled again during the transportation unloading and return'of the hopper 91 Its bottom Z is again opened and operations begin over again whereby it is'possible to fill insuccessively; all th] truck-s disposed behind or one anotherp z I This arrangement may be provided to the rear of a ballast-distributing truck provided or not with sifting means, the working being obviously similar in both cases. It may be used also for removing clay from the track platform or for making it deeper and generally speaking in all cases where material of any kind producedfor instance by earthwork or the like is to be removed and loaded on trucks disposed on or moving along the railroad. r

After such material has been loaded as explained on trucks such as 2 through the agency of the above described loading system, the trucks have tobe emptied. In or dinary earthwork yards, the problem of unloadingearth or material loaded on trucks is generally solved either by unloading the trucks with shovels or .by using tip ing wagons. Self unloading hopper cars which are of interest in certain particular cases are not adapted for unloading earth in embanking because their contents fall too near the track. As, on the other hand, it is diflicult to provide tipping means :for. large-sized standard gauge trucks, it is necessary in most cases to unload the trucks with shovels which is obviously costly and immobilizes a considerable number of trucks owing to the length of'operation. The unloading is particularly diflicult in the case of ballast trucks with high rims and when it is desired to unload thematerial at any point of the railroad which is the case for instance for the Waste from ballast-sifting which waste is generally thrown out on the embankment near the place of sifting so as to avoid any long transportation.

These drawbacks which would considerably reduce the interest of the direct loading arrangement which is one of the features of our invention as described may be removed by the unloading means which form a complementary feature thereof. Referring to Figs. 8 and 4: these unloading means are carried by aframe j running over the rails e e secured to the sides ofthe tracks as explained hereinabove whereby said frame maypass from one truck tothe next.

Thus only one frame is required for the whole train of similarly equipped trucks. 7

The frame j carries an arrangement of chains 0 and buckets carried by a pivoting support 70 held through the crane w and the cables 10 The support maybe raised into the position 70 higher than the truck rim when the frame is topass from one truck on to the next. I

The chains '0 are driven from a shaft p to which are keyed central bosses p similar to those used on excavators. In the machine illustrated, there are three chains used carrying two 'sets of buckets 1" 13 adapted to remove the material throughout the width of the truck. Of course, the number of chains the band conveyor 8, which runs transversally with reference to the track and moves with a speed sufficient for projecting the material on to the desired spot.

All the movements of the arrangement such as the control of the bucket conveyor, the raising of its pivoting support, the con- ,trol of the transverse conveyor, the progress ofthe carriage are. obtained through one or more motors of any descrlption of the gasoline, electric or any other type, the control being effected through a plurality, of parts acted upon by the machinist.

The whole arrangement is such that it riage'g for the track on which the truck runs. 7 1 V Under such conditions the train arriving at the point where the earth or the like is to be unloaded, the pivoting support being in its position 70, the apparatus is started. The

buckets are filled as they pass through 14 and empty their contents over the conveyor 8, which projects the material at the desired point u The automatic advance motion of the frame in the direction n ensures an excellent filling of the buckets. When the frame arrives over point 9 the truck is empty. The pivoting support is raised into its posi-. tion and the frame jis moved over the next truck .2, where operation is resumed.

Figs. 5 and 6 illustrate a modification of this. device. Instead of using buckets digging afterthe manner of excavators, we may prise more or else only one the width of which is smaller than that of'the truck the whole width of which is swept in this case owing to a transversal motion of the bucket chain.

In the last modification shown, -.all the movements are controlled mechanically.

Our invention covers also the method of working corresponding to the use of the above described truck equipments.
