TROLLEY FOR ELECTRIC RAlLWAlYS HAVING OVERHEADWIRES FOR SUPPLY 0F CURRENT.

SPECIFICATION forming part of Letters Patent N o. 738,305, dated September 8, 1903. Application filed .Tune 28, 1902. Serial No. 113,669. (No model.)

To all whom, t may cm1/eerie:

Be it known that I, AMDE FAYOL, engineer, a citizenof the Republic of France,rcsid ing at 9 Rue Matignon, Bordeaux, in the Republic of France, have invented certain new and useful Improvements in Trolleys forElectric Railways Having Overhead Tires for the Supply of Current, of which the'following is a specification.

The present invention relates to an improved trolley for electric railways having an overhead wire for the supply of current comprising a rod carrying a current-taking roller and which is mounted on a vertical pivot or swivel intended to be fixed to the roof of the car.

The main features of this novel trolley are for the purpose of rendering its operation casier, smoother, and safer, and they will be specically described hereinafter with reference to the accompanying drawings, which show, by way of example, one form in which my invention may be carried out.

Figures 1 and l show the improved trolley in elevation. Fig. 2 is an elevation of the lower part of the trolley. Fig. 3 is a vertical section ofthe said lower part on the line A B of Fig. 4. Fig. 4 is aplan ofFig. 1. Fig. 5 represents an elevation of the upper part of the trolley. Fig. 6 is an end elevationof the trolley. Fig. '7 shows a vertical section of the same on the line A B of Fig. 6. Fig. 8 is aplan of the trolley. Fig. 9 represents a vertical section of a lateral guide-roller. Fig. 10 is a plan of the bearing of the said guide-roller. Fig. 11 is a part elevation of a modiiied form of the upper part of the trolley. Figs. 12 and 13 represent, respectively, an elevation and a plan of a guiding-piece. Figs. 14 and 15 show, respectively, a side elevation and a front clevation of an oscillating guide used for putting the trolley in place against the wire for the supply of current. Figs. 16 and 17 represent, respectively, a front elevation and a side elevation of a trolley provided with a bifurcated or fork guide. Fig. 1S shows a trolley provided with a guide having a balance-weight. Fig. 19 shows a modified form of the bifurcated guide. Fig.20 represents another modified form of the said bifurcated guide.

The improved trolley comprises a currenttaking roller 1, the trunnions 2 of which are engaged in the apertures of ablock 3, pivoted to a metal support 4, pivoted in turn to the upper end of the troliey-rod 30. On the said block 3 are formed two parallel arms 6, extending in a direction perpendicular to that of the pivot 7 and carrying the axis 8, on which oscillates a guide-arm 44. On the said block 3 is arranged, as shown by Figs. 5 to 8, the axis 2O for the wheels 21, on which rest the trunnions 2 of roller 1, the said trunnions having a certain amount of play in wells formed by two parallel faces 22. The position of axis 20 relatively to the axis of roller 1 and to the point of contact of the latter with the wire 12 for the supply of current is preferably so determined that the divers forces acting on roller 1 (upward pressure exercised by the wheels 21 on the trunnions 2, downward reaction of wire 12 on roller l, friction of the latter on said wire and friction of the trunnions on wheels 21) shall be substantially equalized, so that the said trunnions 2 bear, without any great pressure, sometimes on the front face and sometimes on the back face of the wells 22, thus reducing wear to a mini mum which is hardly preceptible.

On either side of roller 1, the periphery of which is cylindrical, are arranged the guiderollers 24, pivotally mounted on supports 25, xed to the block 3, so that when roller 1 is applied under the overhead wire 12 the rollers 24 lie on either side of the said wire, and thus prevent roller 1 from moving sidewise relativelyto the wire. It will be understood that the only points of Contact that the said guide-rollers 24 can have with wire 12 or with the tubular supports of the latter, even in the curves of the` line, will always be on the nearest generating parts of the said rollers` that is to say, in the vertical plane passing through the axis ofA rollers 24, and which passes also, or nearly so, through the axis of roller 1. The result is that rollers 24 are never subjected on the part of the deviated parts of the overhead line to any oblique reaction relatively to the horizontal plane and having a tendency to throw the trolley out of the wire, as occurs with deep-grooved rollers. The surface of roller 1 may be slightly concave, as shown by Fig. 11.

Instead of guide-rollers 24, which run along wire 12, l may use fixed guiding-surfaces IOO rubbing against the said wire-such, for example, as lugs 26-rigidly fixed to block 3, as shown by Figs. 9 to 11, the said lugs presenting, one in front of the other, cylindrical vertical convex surfaces 27, which produce the same effect as the surfaces of rollers 24.

The socket-support 4, in which is mounted pivot 7, is pivoted at 28 in a block 29, fixed to the upper end of trolley-rod 30, and it rests by means of pins 3l on the outer part of said block 29, so that it is capable of oscillating upward when required. Furthermore, shielding projections 32, the edges of which are suitably inclined, are formed on the several parts of the head of the trolley, so as to prevent the latter from catching in any way the overhead wires or their supports. Likewise, rod 30 is bent at 33, (see Fig. 1,) so as to present a fairly long horizontal part, which can come under the overhead wires met with obliquely to prevent the trolley from moving upward and which can also cause the head of the trolley to move downward and escape from A the wires in case it jumps into the acute angle of two wires before coming to the crossingpoint of thelatter. These arrangements prevent the trolley from catching or damaging the overhead wires.

Figs. 1 to 4 show the details of the lower part of the trolley. On the roof of the car is firmly fixed a Vhollow pillar 34, within which can turn a vertical pivot or swivel 35. At the upper part of the said swivel is rigidly fixed a block or head 36, on which is pivoted at 37 the lower end of rod 30. The block or head 36 is provided with two downwardly-extending arms 38, and rod 30 is provided with an arm 39, extending above pivot 35. Spiral springs 40 put under proper tension are attached on the one part to said arms 38 and on the other part to arm 39, and thus move rod 30 upward in applying arm 39 to the head of swivel 35. The latter is provided with an adjusting-screw 41, by means of which the highest raising of the trolley can be varied. The lower end of swivel 35 rests in a socket 42 at the bottom of pillar 34, and its upper part, which passes with a great deal of play through the aperture of the pillar, bears on the outer edge of the latter through the medium of a roller 43, mounted on the block or head 36. The result is that the trolley is constantly capable ofoscillating around the lower end of swivel 35 and the point of contact of roller 43 with pillar 34 without meeting with the least resistance frictionally to the extent allowed by the play in the aperture of the pillar-that is to say, to the extent corresponding to an oscillation of thirty to forty centimeters, for example, on the part of the trolley-roller. Beyond such oscillation, which is made in the direction of the trolley bythe line or the car are void of any tendency to cause the trolley-roller tov jump sidewise, as frequently occurs with the trolleys at present in use.

In Figs. 14 and 15 l have shown a guide to be used in putting the trolley in place under the overhead wire, comprising an arm 44, pivotally-mounted at 45 in a fork 46, which itself is capable of turning around an axis 8 (see Figs. 1, 5, and 6) between the arms 6 of block 3. Flat springs 47, fixed on either side of the fork, tend to keep arm 44 in line with fork 46, while allowing the same to move to the right or left in slots 48, provided in the body and arms of the fork. By means of a rope 11, attached to fork 46 and passing around the hub of the same and which is pulled downward, one can cause the fork, together with arm 44', to oseillate upward, as

shown by the arrow in Fig. 1, while in leaving hold of the said rope the fork and arm can move downward. To put the trolley in place under the overhead wire 12, one pulls, as usual, rope 11, so th at arm 44 is raised. In this position it is brought against wire 12, and the trolley is allowed to rise. Arm 44 slides along wire 12 and conducts the bottom of fork 46 straight under said wire. As axis 8 of arm 44 is somewhat removed from pivot 7 of block 3, the result is that the pull on rope 11 causes block 3, together with roller 1, to move parallelly to wire 12, so that the said roller comes exactly under the said wire, fork 46 taking on the latter at the same time. Arm 44 remains raised and applied against the wire so long as the car remains stationary, but when the latter is put in motion the friction holds arm 44 backward and causes the same to move down, together with fork 46.

In Figs. 16 and 17 the guide 44, instead of having a single arm, is in the form-of a fork, the opening of which may be twenty to twenty-live centimeters wide and of which the bottom 13 is hardly wider than the diameter of wire 12. The said guide is jointed to an axis 8 in block 3 and is operated, as hereinbefore described, by means of the rope 1-1, attached to a segment 10.

Fig. 18 shows a guide 44, which may be either bifureated or straight and which carries a balance-weight 15 for the purpose of bringing the guide back into the position of rest as soon as roller 1 has been brought into contact with wire 12 and the rope has been left hold of before the car is put in motion.

In the arrangement shown in Fig. -19 the bottom 16 of fork 44 is higher up than the bottom of the groove in roller 1, so that wire 12 rests on the guide and not on the roller. This arrangement is for the purpose of causing the guide to fall back. As soon as the car has been put in motion in the direction shown by the arrow and has traveled a few centimeters the guide, kept back by the friction against wire 12, takes first the positions shown in broken lines at II and lll and then ICO IIO

li'alls by its own weight into the position shown in broken lines at IV.

Fig. 2O shows the bottom 17 of the fork of a guide in which are `fixed two il at springs 1.8, intended to nip wire l2 when the latter is engaged between the said springs. The springs adhering to the wire have the same eilect as the friction of the wire against the bottom of the fork in the previous case.

I may here lstate that the direction given to the trolley relatively to wire l2, as hereinbe- :fore described, can be obtained without the use of a movable guide-arm, anch-in fact, it only requires rope ll to be attached to any kind of organ turning with block 3 of roller 1 or even to the block itself at a point eccentric to the axis of oscillation of the said block to give a proper direction tothe said roller by means of a pull on the said rope.

I claiin-d n l. A trolley comprising a contact-roller, a

block for the said roller, a rod carrying the block, and an operatingLrope, in combination with guides, arranged on the contact-roller block on either side of the upper part of the said roller, and a guide-arm pivoted on the said block and connected to the operatingrope.
