Application filed November 14,190 Serialm, 3 ,637. I v 4 To all whom it may concern:

Be it known that I, GEORGE G. SCIIROEDER,

. a citizen of. theUnited stat-es residing at in the District of Columbia."

and useful Improvements whichthe following is a specification.

" wires,

- motor is provided with four trolley-arms;

each of which is adapted to come in contactwith one of the said current-wires, and each of the said trolley-arms is electrically con scribed; I

The object of the invention is to provide or track. Said car or carrier is fitted'with an electric motor which constitutes a prime; mover and furnishes the motive power; Suspended, preferably, above and extending parallel with each other are four current-. two of them adapted to act for trans-- mitting the current to the motor and two'of;

them adapted to act as return-wires. The

nected with the said motor.

The prime object of the system is to so ar--. range the apparatus that the car may be sent: back and forth upon the cable, stopped atany desired point, and made to travel at any desired rate of speed. The movement of the" car in either direction is controlled by the manipulation of switches and a pole-changerlocated at either terminal station or a way station. Each car or motor is provided witha means to prevent rocking thereof in the;

' line of travel and also to guide the car around- Said means ialso prevents any tendency of the motor to climb or jump the: track. The trolley-arms are also arranged, so as to preyentlateral rocking of the'car.' Said trolley-arms are preferably mounted; upon a base which is pivoted to the top of;

GUI" e S the frame of the motor, so that the said Lrolley-arms may follow the wires while the mator 1s rounding a curve in the track.

Other objects and special constructionsfare presented, which will be pointed out inthe following description and covered in the sub'joined claims.

This system is especially adapted for use excavations.

This invention has relation to aerial elec-. tric transportation systems; and it consists in the novel construction and arrangement; of its parts, as hereinafter shown and de-'- in logging-camps and at mills for bringing in logs from a distance and dropping them at any desired point, also for removing sawed lumber and slabs and other waste from the mill. It may also beused for transporting merchandise and for moving earth, &c., from In fact, its uses are too numerous'to specify,

'vantagein all instances where tion is necessary.

In the accompanying drawings,

Fig. 3 is a side elevation of a car or carrier located upon the track. Fi 4 is an end elevation of the car or carrier Tocated upon the track. Fig! 5 is a s'ide,elevation .of the mo-- tor used in the car or carrier with parts removed. Fi 6 is an edge-elevation, partly in section, a deviceused to prevent rocking of the motor in the line of travel and for the purpose of guiding the same around the curves. Fig. 7 istransportaview of the disk for transmitting the current to the motor; and Fig. 9 is a side elevation,

partly in section, of the trolley-arms and their support.

The system consists of the suspended cable or track 1, above which is located the wires 2 2 and 3 3. All of thesaid wires are parallel to each other and parallel to said track. The electric generator 4 is located at any suitable point. The'wire connects one pole thereof with the switch-socket 6. I The wire 7 connects the opposite pole of the said generator with the switch-socket 8. The fuses 9-9 are located at suitable points on the wires 5 and 7. v The switch 10 is adapted to enter the sockets 6-and 8, and the wire 11 connects one of the ends of said switch with the socket 12, and the wire 13connect s"the otherend of the switchl10 with the socket 141. The wire 15 connects the wire 11 with one of the line-wires 2. I The wire 16 connects the l wire 13 with the other line-wire 2. The said line-wires 2 2 are connected throu h the trolley-arms of the carrier with the 'fie idw of the 1 motor/18.

Figure 1 is v atransverse sectional view of the motor- Fig. 8 1s a horizontal sectional as itmay be used to ad-' socket 22. The pole-changer 23 (shown in 1 in the form of a switch) is adapted to be swung into either the sockets 12 and 14 or I 20 and 22. One end of the switch constituting the pole=changer 23 is connected, by means of the wire 24, with one of the linewires 3, and the opposite end of the said switch 23 is connected, by means of the wire 25, with the other line-wire 3. The rheostat 26 is located, preferably, upon the wire 25. I Both. of the line-wires 3 3 are electrically connected, by means of the trolley-arms of the carrier, with the armature 27 or" the motor 18. he armature 27 is held in a fixed position a ainst rotation, aswill be hereinafter eX- pi ained, while the field 17 rotates about the said armature.

Presuming that the parts are in the positions as indicated in Fig. 2, the current starts 1 from the generator 4, passes along the wire I 5 to the socket 6, then through the switch along the wire 11, then along wire t0 the inner line-wire 2, thence through the arinature 17 along the outer line-wire 2, thence along wire 16 to the wire 13, then through I switch 10 along wire 7 back to the. opposite i pole of the generator 4. At the same time I the current passes from wire 13, through socket 12 and along wire 19, to socket 20, j thence along one en of the switch 23 to wire I 25, t ence along the said wire 25, through rheostat26, to the inner line-wire 3, thence to I the armature 27, thence along the outer linewire 3, thence of the along the cross-wire 21 to socket back to the generator over the wire 13 and its connections. By su plying the current to the armature and ti along wire 24 to the other end switch, thence to socket 22, thence 14, thence 1e field as above de-.

l scribed the said armature is rotated in one; direction. To change the direction ot rota- I tion of the armature, the switch 23 is disengaged from the sockets and 22 and turned i into the sockets 12 and 14. he current ,I then passes from the generator 1 to the field l 17, as above described. 'hile the course of i the current through the armature 27 is re i versed that is, the current passes from the 5 socket 12 along one end ofthe switch 23, then 5 along wire 21 to the outer line-wire 3, thence through the armature 27, thence back along the inner line-wire 3, thence along wire 25, through the rheostat 26, to the opposite end T of the switch 23, thence along said switch to i the socket 14, thence along the wire 13 and 5 its connections back to the generator 4. Thus the rotation of the field 17 about the ar- 1 mature 27 is reversed. To out off the current at any desired point, the switch 10 is disconnected from the sockets 6 and 8, and thus the motor is stopped. The switches 10 and 23 may be included in one instrument, as I may also the rheostat 26, such an instru-, ment being commonly known as a startingbox. At any event the switches 10 and 23 t the upper portion of the extending portion A -19, the tension of and the rheosta-t 26 should be located near each other, so as to be operated by oneperson.

The motor 18 consists of an outer shell or easing, within which the armature 27 and the field 17 is housed. Around the periphery of the said casing extends a grooved annulus 28, which is adapted to 11m upon the cabie 1. The disk 29 is so located as to rotatewith the casing of the motor 18. The outer face of the said disk is provided with metal rings 30, 31, 32, and The outer ring 30 is connected, by means of the wire 34, with one of the brushes of the armature, and the ring 31 is connected. by means of the Wire 36, with the other brush of the said armature. The ring 32 is connected, by means of the wire 37, with one of the fields of the mo tor, the wire 38 connecting the fields together and the Wire 39 connec'ng one of the said fields with the ring 33. Thus the electrical connections through the 1 Mar are cornpleted. The trolley-arms are each provided at their upper ds with a troileywheel 41, and the wires '22 extend down from the said trolley-wheels with the brushes or (2 ends of which bear age 5 32, and The lower ends ti arms 40 are pivoted to crov 1s.. The said trolley-arms at their pivotai poin i are in alinenientwith each other; but two'ot the said trolley-arms extend in one direction and bear against the inner line-wanes 2 and 3, and the two remaining trolley-arms extend back in substantially an opposite direction 1 and bear against the outer line-wires 2 and The crosspieee 4-1 is pivoted at its middle t frame 15, the pivoting-bolt 46 having a ver cal ring through which the wires 42 42 pass. (1 a. frame 45 3 provided with a .t'orwardly and rearwardly 4.7, at the inner ends of which are secured the vertical extending shafts 48. The guide-whecls are journaled at the lower ends of the shaft 48 and are adapted to run upon the cable 1. The coil-springs 50 are interposed between the lower ends oi the portions t? and a suitable collar on the shaft 43 above the Wheels said. coil-springs being to force the wheels 49 away from the lower ends of the portions -17. The side portions 51 and 52 extend down tron'i 51 being secured at its lower end to one end of the shaft of the motor 18, whilethe por tion 52 extends down on the opposite side of the motor 18 and is (?OIiI1t3Ct-O(l.tO the opposite end of the shaft thereof and extends down, forming the shank 53. to which the load 54 may be attached.

it will thus be seen that as the carrier moves back and forth the wheels 4.9 their connections will have a tendency to prc-- vent rocking or the motor in theline of travel. The said wheels will aiso guide the motor in the top 4-5, the portion I around curves and have a tendency to p195i em;- any inclination on the partaof the itiQtortfrom riding up above'the cable 1. The swivel connection between the cross- 5 supporting the, lower ends of the trolleyarms -and the top-piece eta the frame compensate for any change in direction which might occur between the. current-wires notwithstanding any such lack of 10 alinement, the trolley-arms 40 being pivmted insalinement attheir lower ends to the crossapiece 44 andextending up and in front andtbehind a perpendicular erected from the ceiitr'o f the motor 18, having a tendency'to r5 "vent any lateral rocking of the motor or m'loadcarried by the same.
