'd have invented certain new and useful Inivproyements in. Aerial Tramways, of which the `following is speciiication.

This invention has relation to aerial tramways; and it consists in the novel const-ruction and arrangement of its parts, as hereinafter shown and described. V

The object of the invention is to provide a tramway of the nature as stated which is especially adapted to be used for mining pur-` poses and for transportation ,to and from mines.

. The invention consists primarilyT of an elevated track Orr-ail of special formation, which is supported upon vertically disposed I- beams. The said beams are provided with socketed upper ends, the sockets of which are adapted to receive the depending body of the The side flanges of the sockets project into spacesforined between the body of the rail and the webs or flanges formed therewith, the outer faces of the flanges of said sockets being formed with seats to receive said webs and conforming thereto. In this manner the rail is effectively braced and supported. The uper ends of the beams are irst slit and then expanded to forni the sockets. Suitable insulation is interposed' between the rail and its supports, as the rail is used. as a ground-return for the. current employed for the puro'f propelling-'the motors or cars that At the joints of the rails side iish-plates are employed. Said lishplates are provided with longitudinally-extending grooves, which receive electric bonds and house the same. The ends oi the said bonds are in contact with the ends of the adjacent rails, said connection being effected in the usual manner. The lower ends of the --beams are embedded inthe ground, and

suitable braces extending in the line of the track are provided at the lower ends of the said beams.

From the following description other objects and advantages will appear as the tea-z tures of the invention are revealed.

In the accompanying drawings, Figurel is i a scenic view of the tramway 'associated withA a mine. Fig. 2 is a transverse sectional view yfish-plates attached thereto.

in the ground.

of the tramway, showing a motor in elevation thereon. Fig. 3 is a top plan view of a section of the tramway, showing the motor thereon. Fig. 4 is a side elevation of one of the track-supports with parts broken away. Fig. 5 is a side elevation of the meeting ends of the track-rails with'parts' broken away. Fig. 6 is a transverse section of a rail with the 7 is a side elevation of the inner face ofa fish-plate. Fig. 8 is a horizontal sectional View of the I-beam,

-and Fig. 9 is a side elevation oi an intermediate portion of an I-beam.

The track-supports consist of the I-beams l l'1, which are embedded at their lower ends At suitable intervals the said I-beams are provided with the braces 2, which are bolted or otherwise secured at their upper ends to the side flanges of the. beam and extend downward in the line of direction of the track and are embedded at their lower ends in the ground. The incision or slit 3 is formed at the upper ends of the said beams, and the said upper ends of the beams are expanded or spread laterally, as at 4.

The track-rails 5 are provided with the top flat surfaces 6 and the sidev inclined webs or tlanges 7 7. The central body 9 extends down from the head ol' the rail 5 and at its upper yportion is spaced from the inner faces oi" webs 7. The extremities of the split portion of each beam l are shaped to it between the iianges 7 and body 9 and form seats for the lower edges and inner faces ofsaid webs.

The arm 10 is suit ably secured at an intermediate point in `laterally-disposed perforations bored in the ilanges of the I-beams 1. The electricwires l1 11 are supported by the outer ends ofv the said arm 10. The said wires extend parallel to the track of the tramway. A

A t the ends of the track-rails 5 5 the electric bonds 12 are located. The said bonds have their ends secured in perf-orati'ons pro-- are bolted. The said plates are located under the heads of the Arails and in the spaces between the body 9 and the side webs 7.. .The bolts 14 14 pass through registering perforations in the body 9 and the flanges of the I-be'arn 1 and secure the rails 5 to .the'upper ends of the said supports. The insulation 15 is interposed between the under surface of the rail 5 and the upper end of the support `1 and also around the bolts 14.

The motor or carrier consists of the traction-Wheels 16, which run upon the rail 5 and are provided with the side flanges 17, which bear against the outer surfaces of webs 7' 7 and prevent any-tendency of lateral rock in the motor. The electric current is transmitted to the motor over the Wires 11 11 and is carried to the-fields of the motor (not shown)` by the trolley-arms 18 18 and is grounded over the track 5. The frame 19 is lmount-ed upon the motor and straddles the track 5 `and is provided with the depending hangers 20 20, to the lower ends of which the buckets 21 are attached. As the said motor and its construction form no part of this invention, it is deemedv unnecessary to go into detail description ofthe same here.

Having described my invention, what .l

claim as new,land desire to secure by Letters 3. A monotrack-tramway comprising up.

rights having tfheirupper ends split and expanded to form sockets, and rails having-flat top surfacesand. outwardly-sloping Alianges depending from said top surface, the body portions of said rails being secured in the split portions of said uprights.

4.' In a tramway, an elevated monotrack comprising rails, bonds electrically connecting the rails together, beams supportingr the rails Aand having their 4upper ends split and expanded to form sockets which receive said rails, and insulation interposed between the beams and the rails.

5. In a tramway, an elevated monotrack comprising rails having spaced-apart webs forming side iianges andA depending integral bodies interposed between said webs, bonds electrically connecting the railsv together, beams support-ing the rails and having ,at

their upper ends sockets which receive vthe frail-bodies, the upper ends of the beams iitting between the iianges and the body ot the rail. l n gj y6. In a tramway, an elevated monotrack flanges. .v y '9. A monotrack-tramway comprising rails comprising rails having inclined spacersi apart webs forming side flanges and centra depending integral bodiesinterposed between said webs, bonds electrically connect-ing the rails together, beams supporting the rails and having at their upper ends sockets which receive the rail-bodies, the upper ends of the beams fit-ting between t-he flanges and the body of the rail. y

7. A monotrack-tramway comprising rails havingr spacedapart webs forming side iianges, and depending integral bodies interposed between said webs and spaced from said flanges, and supports for said rails having means for engaging the lower edges of said flanges.

S. A'monotrack-tramway comprising rails having' spaced-apart webs forming side ianges and central depending integral bodies interposed between said flanges, and sup ports for said rails having means for engag ing said bodies andthe lower edges 'fof said havin@ inclined side flanges and de ,endinCr b h bodies interposed between said webs, andv supporting-beamshaving their ends j provided with seats for said side iianges.

'Y 10. A- monotracktramway comprising rails having"l inclined side flanges and central depending bodies interposed between said flanges, and supportingbeams having their outer faces provided with sea-ts for said side anges. A

11`. A monotracl-tramway comprising -rails each having spaced-apart webs forming side flanges and an integral depending body interposed. between said webs,` bonds elec.- trically conneting said webs, and beams having their ends` provided with sockets to receive the bodies of the rails, said sockets ybeing also provided with exterior seats for' said lianges. I

l2. A monotrack-tramway ctnnprising rails having spaced-apart webs forming inclined side ,Hanges and depending bodies integral with and interposed between said webs, bonds attached to said bodies;iish-plates lo` cated over the bonds and attached to the depending bodies, and means for supporting the rails, said supporting means also engaging the lower edges of said webs.

ln testimony whereof l have signed my name to this specification in the presence et two subscribing witnesses.
