Similar reference characters designate similar parts in the different views.

1 designates acar body provided with car wheels 2 adapted to run on rails 3 and. which are'secured to an axle 4 having secured to it a gear wheel 5 which meshes with a pinion 6 secured to the armature'shaft 7' of a motor 8 carried by the car body' 1.

e inner side of each wheel 2 is rovided with a metal contact plate 9 which is with a steel tire 10, Fig. 2, which bears upon theadjacent rail 3.

Longitudinally slidable respectively in two horizontal transverse tubes 11- are two contact pins 12 which are respectively normally forced against the plates 11 by two coil springs 13 -respectively mounted in' the tubes 11 and which respectively bear at their inner ends-against two screws l4.- adjustably mounted in the inner ends of the tubes 11. The latter are respectively supported in bearings 15 which are secured to the under side of the car body 1.

Secured to the under side of the l is a reversing switch mechanism ing the following described parts.

A horizontal plate 16, of insulating material, is secured to the under side of the body 1 and has secured-to it two downwardly extending supporting members 17, Fi s. a orizontal transverse shaft 18 to which is secured a fiat rectangular block 19, of insulating material, whlch has mounted upon it two contact plates 20 and 21.

Secured to the plate 16 at one side of the oscillatable contact carrying block or member 19 are two spring contact plates 22 and 23, which are always respectively in concar body comprisenlarged vertical sectional- 5 t0 7 in which is oscillatably mounted.

and 21. Also secured sectionof oneof the rheoto the plate 16 are two spring . contact plates 24 and 25, which are adapted to respectively bear upon the contact plates 20 and 21 when the contact carrying member 19 is swung to one position, and which are adapted to slide 'ofi from said contact plates, when the contact carrying member 19 is swung to the position shown'in Figs. 3, 5 and 11.

Secured to the plate 16 at the opposite side of the member 19 are two spring contact plates 26 and 27 which are adapted to respectively bear against the contacts 20 and 21 when the member 19 is in the position shown in Figs. 3 and 5, and which are adapted to slide off from said contacts when the member 19 is rocked to the position shown in dotted lines in Fig.5.

For the purpose of oscillating the contact carrying member 19, a solenoid is provided comprising .a helix or winding 28 secured to the plate 16, and having reciprocative therein a magnetizable core 29 which is secured to one end of a horizontal oscillatable member comprising a bar 30 which is slidably mounted in a hole provided in a bracket 31 depending from the plate 16. The bar 30 is provided with a longitudinal slot 32 through which extends the shaft 18.

Pivoted by a horizontal screw'33 to the bar 30 is an arm or member 34, Fig. 5, which is yieldingly held in the horizontal longitudinal position by a vertical spring 35- having at its lower end a recess 36 which has mounted in it one end of the arm of member 34. The upper end of the spring 35 is secured to a plate 37 attached to the bar 30. The other end of the arm 34 is adapted to enter either of two notches 38 and 39 rovided in one end of a plate 40 whic is rigidly secured to the adjacent end of the block or member 19.

A U-shaped plate 41 which is secured to vthe bar 30, Fig. 5, has its arms arranged to engage and limit the oscillating movement of the block or member 19.

\Vhen the helix or winding 28 is energized, the core 29 will be drawn therein, thus sliding to the right, as viewed in Fig. 5, the bar 30. The arm 34, with the parts as shown in solid lines in Fig. 5, will enter the notch 38 and swing the 40 and member plate 19 to the position shown in dotted lines in i Fig. 5, thus rocking the member 19 so that spring the contactsprings 26 and 27'vvill slide onto the contactplates 20 and 21, and the contact springs 24 and 25 will slide off .from said contact plates, thus reversing the direction of the current passing 8, as will shortly be described.

For the purpose ofyieldingly holding the plate 40 and member 19 in its two operative positions, there is provided I an upright 42,'Fig. 5, the upper end of which is secured to the plate 16 and the lower end of which is provided with a lateral V-shaped through the motor I projection 43, which is adapted to bear against the two oblique edges or a V-shaped projection 44 which is provided at the end or the plate 40 opposite to the end containing the notches 38 and 39.

For restoring the core 29 and bar- 30 to the osition shown in solid lines in Figs. 5 anc 6, an upright spring 45 has its upper end secured to the plate 16 and has its lower end bearing against the right side of the screw 33, as viewed in Figs. 5 and 6. By reason of the employment of the spring 45 for restoring the core 29 and bar 30 to the initial position, shown in solid lines in Figs. 5 and 6, after the core has been energize and then denergized, such restoration of the core will be effected regardless of its position with respect to the horizontal, as, for example, when the vehicle is on a steep grade, when the vehicle which is controlled by the reversing mechanism is an automobile, or, in case the vehicle is an aeroplane, when the latter is in other than a horizontal position.

WVhen a continuous current is employed, the circuit arrangement shown in Fig. 3 is used. As shown in this figure, a conductor 46 connects one end of the helix 28 with end of the winding 48 magnets of the motor 8, the other end of said winding being connected by a conductor 49 with the contact spring 22. The other end of the helix 28 is connectedby aconductor 50 with one end of the winding 51 of the other field magnet of the motor 8. The other end of the winding, 51 is connected by a conductor 52 with the contact spring 23.

v The contact springs 24 and 25 are respectively connected by conductors 53 and 54 with the two brushes of the motor 8.

A conductor 55 connects the contact springs 24 and 27, and a conductor 56 connects the contact springs 25 and 26.

With the parts as shown in Fig. 3, and assuming the lower rail 3 to be the feed rail, when the current is turned on, it will pass from said rail through the adjacent wheel 14, thence through conductor46, helix 28,

conductor 50,.windin 51, conductor 52, contact plates 23, 21 an 27, conductor 55, contact spring 24, conductor 53, motor 8, conductor 54, contact plate 25, conductor 56, contacts 26, 20 and 22, conductor 49, winding 48, conductor 47 and the other screw 14,

spring 13, and pin 12, 'tothe opposite wheel 2 and thence to the returnra'il 3'.

The helix 28 will he energized, thus, drawing in the core 29 and pulling the bar 30,

so that the arm 34 enters the notch38, thus reversing the switch to a position in which the contacts 24 and 25 will rest onthe lates 20 and 21 and the contacts 26 and 2 will pass ofi from said plates 20 and21. The

the feed rail 3' e contact plate movement of the car.

When an alternating current is to be used, the circuit employed is that This circuit is the same asthat shown Fig. 3, excepting that the helix 28 is not in series with the motor 8 but is-in a'shunt circuit. 1 Referring to Fig. .11, one end of the helix 8 is connected by a conductor 57 with the conductor 47. The other end of the helix 8 is connected by a conductor 58 with a conductor 59 which connects one end of the winding 51 with the adjacent screw 14.

e current will n w pass from the feed 0 rail 3 to the adjacent tor 58, helix 28 and conductor 57 to the conductor 47 on of the current in the manner already de scribed. I

In Fig. is shown a circuit arrangement to be employed in connection with elther of- 1 riphera l teeth of a ratchet wheel 80, which 1s t e circuit be used respectively in conJunction there- 60 with, description of one track and controlling mechanism will sufiice, as both are alike. Each track has a feed rail 3 and a return rail 3. The tracks are endless. tracks The current will the mova shown in Fig.

he arm 69 is adapted to engage a contact 6 which is connected by a conductor 77 withthe operating lever 60 of the rheostat.

en the switch arms 68, and

position shown, thecurrent will pass from the feed wire through the conductor 73, post 71, arm 69, contact? 6, conductor 77, lever conductor 62 to the 7 feed rail 7 3, thence through the solenoid helix 28, reversing motor 8, as hereinbefore described, to the return rail 3, from which the tact 64, coil 65, conductor arm 68, post turn wire 74.

By throwing the operating lever 60 from the operative to the neutral position and then again to the operative position, the

ife switch being closed, the reversing switch on the car w1ll be operated to reverse 66, contact 67, 70 and conductor 72 to the rethe current through the motor 8, thereby.

reversing the direction car, as above described. In orderthat the operator may know Whether the particularcar controlled bg tie of movement of the ward, the following described indicating mechanism is provided Referring particularly to Figs. 12to 14, designates the rheostat casing, which has p voted to its nner wall a pawl 79, which secured to a mounted lever 60. I I

Also secured to the shaft 81 is a wheel 83 its row of letters, in which the letters F and B alternate with eachother and which indicate shaiit 81, which is rotatably in a casing 82' carried by the a variable resist- 60,, coils 61,

pass by the conductor 63, conperiphery. with a circular ling means actuated by said respectively whether the car indicated by this device is moving forwardly or backwardly. The letters F and B are adapted,-

when the ratchet wheel 80 and wheel 83 are rotated step by step, to consecutively appear at an observation opening 84k which is provided in the periphery of the casing 82.

Whenever the lever of the rheostat is moved from the closed or operative position, to the neutral position, the pawl 7 9 will engage a tooth in the ratchet wheel and turn the latter and the wheel 83 forward one step, so that the next letter on the wheel 83 will appear at the observation opening 84. If the car has been moving forwardly, the letter 1* will appear at the observation opening. It now the lever 60 is thrown to the neutral position, the wheel 83 will be advanced one step and the letter B will appear at the observation opening 84:, indicating that as soon as the rheostat lever 60 is swung from the neutral to the operative position, the motor of the particular car controlled by the lever, or the cars, it there are more than one on the same track, will be operated to reverse the movement of the car.

A plurality of cars, if desired, equipped as above described, may be operated upon each track, and there may be as many tracks as desired.

A knife switch 85 similar to the one just described respectively connects the wires 75 and 7 at with conductors 86 and S7. The conductor 87 is connected to a resistance coil 88 operatively connected with a movable contact 89 which is connected to the conductor ('33. The conductor 86 is connected with a rheostat lever 90 similar to the lever 60 and adapted to cooperate with resistance coils 91 which are connected by a conductor 92 with the outer rail of the outer track which corre sponds to the rail 3 and is designated by 93. The inner rail 9% of the outer track, corresponds to the rail 3 and is connected to the conductor 63. The operation of the mechanism just described is the same as that of the mechanism which includes the lever 60.
