    G. $ J. Gibsons Improved Machinery for Haismg Soil or Earth from Sewers. the endless travelling band or platform Z, l. The shoots k are constructed by preference of galvanized iron plate fitted on to a wooden bottom, and provided with light angle iron sides. Cast iron carriages k* are fixed on the hinder part of the shoots k, and are provided with small rollers, which work on iron rails m, m. The shoot is made to traverse to and fro on the iron rails m, and 5 to pass between the descending buckets on either side, and the buckets discharge their contents on to the shoot as the latter approaches the respective chains. The movement of the shoot to and fro between the buckets is effected by means of the excentrics n, n, which are mounted on the transverse shafting /. The arms of the excentrics are connected to levers n\ n2, which 10 have their fulcra at nx. The lower ends of these levers nl are connected either directly or by means of links to the sides of the shoot k, and therefore, as they are worked, they move the shoots to and fro on the rails m, m. The soil is discharged from the shoots k on to the endless travelling platform Z, Z, , which is proposed to be formed either of good strong tarred canvas working 15 round cylindrical drums, as shewn in the Drawing, or it may be constructed of endless chains or bands, to which are secured wrougkt-iron plates of suitable width and length, each plate being made to lap over that adjoining. The plates should be rivetted on to three endless chains made of square links, each about five inches long; the plates must be rivetted on to the solid links, and 20 the hollow links fit over a peg on hexagonal or other suitably-shaped pullies, which receive motion from the upper longitudinal shafting E by means of an endless leather strap or band passing round suitable pullies, as shewn in Fig. 1. By this means motion is conveyed to the platform or travelling endless band, which passes round a similar but smaller pulley at the outer end, which is 25 supported by iron rods l*. The soil is by this means carried forward on the travelling platform or endless band over the side of the excavation, and is deposited in a heap, as shewn in the Drawing, or is allowed to fall into carts, earth waggons, or wheel barrows, as required, by means of a crossed driving band and a similar shafting to that described as working the platform. On 30 one side of the apparatus a similar platform is made to work on the opposite side of the machine for the purpose of discharging the excavated soil on the other side, if it should be considered more convenient to deliver the soil on both sides simultaneously. Having now described our Invention of “ Improved Machinery for Raising 35 and Removing Soil or Earth from Sewers and other Excavations,” and having explained the manner of carrying the same into effect, we would remark that, although we have shewn and described the best method with which we are acquainted for carrying out our Invention, it will be evident that the arrange-
