To all whom it may concern:

Be it known that I, WILLIAM LINDSAY HAMILTON, a subject of the King of Great Britain and Ireland, residing at 39 Bothwell street, Glasgow, Scotland, have invented new and useful Improvements in or Connected with Means for Tipping Rail-Supported lVagons and the Like, (for which I have made application for patent in Great Britain, No. 19,574, bearing date August 22, 1910,) of which the following is a specification.

This invention which relates to means for tipping rail supported wagons and the like, is devised for the purpose of discharging material out of wagons supported by an elevated track, and is particularly adapted for use in systems in which material is required to be conveyed to a storage ground or other place and discharged at one place, or discharged at positions which are periodically advanced so that the discharged material accumulates upon the ground in the form of an advancing bank; the invention is alsoadapted for use in forming railway and other embankments.

According to this invent-ion, an elevated railway is provided to extend over the area upon which the material is to be discharged, upon which the wheels of carriages depending from the railway are adapted to run, and at a station where the discharge is to be effected the railway is furnished with means adapted to enter into working engagement with mechanism for tipping or inverting each carriage as it enters the stat-ion, associated, if required, with means for returning the carriage to its upright position as the carriage passes out of, or after it has left, the station; and in order to effect the discharge at successive positions provision is made whereby the station may be advanced progressivelv and the continuity of the railway maintained. 1

Some examples of construction and application of means according to this invention will now be described with reference to th accompanying drawings, in which 5- v Figure 1 is a side elevation of a portion of an elevated railway arranged and furnished according to this invention. Fig. 2 is a side elevation, drawn on a larger scale, of a carrier suspended from the railway in its upright position with a wagon mounted therein, Fig. 3 is an end view of Fig. 2 showing the railway of Fig. 1 in cross section, and

Fig. 4 is a, side elevation, corresponding to F1g 2, showing the carrier in an advanced posltlon on the track with the carrier tilted for discharging the contents of the wagon.

Fig. 5 is a side elevation partly in section, and Fig. 6 is a cross sectional end view of a form of aerial or suspended railway associated in a construction according to this invention. Fig. 7 is a side elevation of a railway of the type illustrated at Figs. 5 and 6; and Fig. 8 is a plan of an endless railway of the same type, arranged and furnished according to this invention. Fig. 9 is a cross section and Fig. 10 is a longitudinal section of a track furnished with a rack.

The elevated railway arranged andfurnished as shown at Figs. 1 to 4, comprises standards A carrying two cables B B in suspension, spaced apart and arranged parallel to one another. From each cable links C depend, their lower ends being fixed to a series of rigid rails D coupled together, forming a railway having a double track upon which the wheels of carriages, depending from the railway, are adapted to run.

In the forms of construction illustrated, at the station on the railway beneath which the discharge is to be made, one of the tracks is furnished witha rack E, projecting from the underside of therail D. For use in association with a track of this description, carriages, or carriers for wagons, hereinafter referred to as carriers and geneally designated by the letter F, are provided, comprising in construction a frame F upon which the wagons are adapted to be wheeled and fixed when in position, and furnished with means such, for example, as a toothed wheel G adapted, as the carrier advanced, to enter into engagement with the rack E at the discharging station and by rotation impart a turning movement to the frame F so that the wagon is inverted or tipped sufliciently to discharge its contents. After discharging, the carrier may be drawn back, or it may be further advanced, and in either case the means may be arranged to act, or permit the frame F to be returned to or to assume its upright position. In' the form of construction shown at Figs. 2, 3 and 4, the turning motion is transmitted from the toothed wheel G, which engages with the rack E to the frame F by means of a chain I-I operating a toothed pinion H fixed on the axle, of the frame F the axis of which is transverse to charge, or it may be used in cases where the frame tends to assume its upright position after the wagon has been discharged. A modification of this form of gearing is shown at Figs. 2, 3 and 4, for use in a system where the direction of travel of the carrier is not reversed and in which the frame is tilted in one direction and then by a reverse motion brought back to its upright position. This system is particularly adapted to be embodied in the construction of an endless track as indicated at Fig. 8. In the modification shown at Figs. 2, 3 and t, the motion transmitted by the gear wheel G engaging with the rack E turns the frame from its upright into its inverted position for discharging the contents of the wagon, the frame being returned to its upright position by operation through an auxiliary gear wheel G arranged to engage with an auxiliary rack E which transmits a reverse motion to the shaft on which the gear wheel G is mounted. The racks E and E and their complementary gear wheels G and G are set in different paths relative to the run of the track so that the gear wheel G which engages with the rack E passes clear at the side of the rack E and the gear wheel G which engages with the rack E passes clear at the side of the rack E.

- The rack E may conveniently be placed some distance in advance of the rack E, but they may be placed close together if desired.

This invention is particularly adapted to be associated in construction with aerial or suspended railways of a known type, an example of which is shown at Figs. 5 and 6. This type of railway may comprise a single or a double line of rails for the wheels of the carriers to run on. The example illustrated has a double line of rails, and comprises two longitudinal assemblages of sections, each section being formed with a continuous yoke J to rest upon a cable K in suspension, and having a continuous suspender J depending from the yoke and a continuous way D, supported by the suspender, for the wheels to run upon, the arrangement being such that each section is wholly supported throughout its length by resting upon a cable in suspension and every portion of the line is supported by direct suspension from its cable, and the sections, of which there is a series coupled together in each assemblage, have some freedom of angular movement relative to one another. A more detailed description of the type of railway in question is contained in the specification of W. L. Hamiltons Patent No. 978581 dated 13th December, 1910. In application to railways of the 1V. L. Hamilton type as defined generally with reference to Figs. 5 and 6, any longitudinal section comprised in the formation of the track may be furnished with a rack E having a series of teeth sufficiently long to impart any of the motions required to be given to the carrier. In practice, the rack E may in one form of construction be fitted to the section, and be located, for eX- ample, on the underside of the way of the section, and in order to enable a rack to be placed at any position along the line, provision is made for fastening a rack at any station, for example, by bolts, the line having appropriate apertures or fittings for the purpose.

In aerial systems of. the description in question where the carriers are drawn along and returned in the same direction, the track, as indicated at Fig. 7, need not be completed beyond the station, but it may be convenient to furnish a part in order to support the carrier if overhauled beyond the station. To permit the station to be advanced in stages progressively, a series of longitudinal sections may be provided adapted to be inserted and assembled with the other sections on the cable or cables.

lVith the object of insuring that the toothed wheel G or G may more readily enter into mesh with the rack, the initial tooth of the rack, as shown at Figs. 9 and 10, may consist of a roller L, but in the form of construction shown instead of the initial tooth only consisting of a roller all the teeth shown are composed of rollers.
