SPECIFICATION forming part of Letters Patent No.1536,482, dated March 26, 189 5.

Application filed July 10, 1894:.

To a/ZZ whom/ 11i/ay concern:

Be it known, that I, JAMES H. REINHARDT, of Newark, in the county of Essex and State of New Jersey, have invented certain new and j useful Improvements in Railway-Switches; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates particularly to switching devices for-street railways whereby the position of the switch-tongue may be controlled from an approaching car and such carturned to one branch or the other as may be desired. The object particularly' in view is to provide a device of this character which shall be reliable under al1 conditions of vuse and particularly one which shall be specially adapted for use upon electric railways.

A practical application of the invention will be described in detail hereinafter and the fea! tures of novelty will be set forth in the elaims.

The invention relates in part to the means whereby the electrical current which is relied upon to set the switch actuating devices, may be directed as required to produce the result desired, in` part to the devices for completing the circuit of the energizing current from the moving car to the devices which directly control or effect the setting of the switch actuating devices, in part to such controlling devices and in part to the mechanical devices whereby the approaching car is itself caused to shift the switch inthe direction which has been predetermined. f

Referring first to Sheet l of the drawings,

. I will proceed to describe the mechanical devices for shifting the switch and the electrical devices for controlling said actuating devices. The rails A, A, ofthe main line, the rails A', A', of one branch, the rails A2, A2, of the other branch and the movable tongue A3 may be arranged in the ordinary and usual or any preferred manner. The tongue A3 is adapted to be engaged, through the medium of a notched piece a3 with an arm B which is rigidly secured to a shaft B. i mounted in suitable bearings beneath the switch and is of a suitable length to insure the full movement of the switch tongue before it is hidden from view b y the approaching car, while its extremity projects through the wall of a casing C and has fixed thereto a double arm D which bears at each end a pin or stud d or d. The casing "isf-made as tight as it may reasonably be made 'to exclude water or dirt but at the same'timethe parts contained within it are so protected, as will hereinafter moreclearly appear, that the presence of dirt or water within the casing would not interfere with the proper operation of the switch.

Within the casing C is mounted to rock endwise a box, or more properly, a hollow lever E, one end being weighted so that it shall standgnormally in the position indicated in Fig.'v2. Near oneend of the box or lever E a pinE projects through the rail above it in 'lhe'latter is ICO Y position to be struck by the wheel of `an approachingcar, whereby the latter shall tilt the lever endwise, the lever returning to normal position after` the car has passed. On the box or lever E is mounted a setting lever F which is free to swing from side to side so that its ext remity may stand under either pin d or pin d' of the arm D and thereby rock the shaft B' and shift the switch tongue At3 in one direction or the other as the car passes, the direction of movement of the switch tongue beingdetermined by the position of the setting lever F. The extremity of the lever F which engages the pins d, d', is preferably provided with two hornsf,f', substantially as represented in Figs. 4 and 5. As the lever E, by reason of the preponderance of the end next the arm D, tilts back to normal position after operation, carrying with it the lever F, the under side of the horn in descending will strike the pin which has just been elevated and, sliding down upon the pin, will cause the lever F to swing back to central position. The lever F is so supported upon the lever E that in addition to its capacity of oscillation from side to side it may also be tilted up and down endwise to some extent. For this purpose it is pivoted, as at g, in the forked end of a pivoted bar G and is guided in a fork g at the other end of said bar. The object of this arrangement is to permit a notched plate f2, which is carried by the forward extremity of the lever, to engage a tooth f3 which is mounted on the lever E, whereby the lateral movement of the lever F is prevented except at the proper time. The means for tilting the lever F will be described hereinafter. Normally the lever F stands in its middle position sothat if the lever Eis tilted bythe passage of a wagon wheel over the pin E' it shall not affect the shaft B', the end of the lever F passing between the pins d, d', and the hornsf,f' not being long enough to strike either ot' said pins when the end of the lever starts directly upward from its middle position.

The bar G is secured to a stud H which is bored ont, as at h, so that it may tit over the tixed pivot pin h which is rigidly secured to the bottom of the boX lover E between two partition plates e and e'. The stud II passes through a cap plate h2 which is adapted to tit snugly over the partition plates e and e' and the side walls of the recess in the lever E to protect'the space beneath from access of dust or moisture. plate h2 is formed an annular channel h3 which may be filled with oil or other suitable sealing substance and may be entered by an annular tiange h4 which is iiXed to the bar G, whereby the entrance of dust or moisture between the stud H and the plate h2 is effectually prevented.

Within the space between the partitions e, e', which is electually sealed, as described above, the stud H receives an armature I and by means of electro magnets suitablymounted within the recess of the lever E the armature Upon the upper side of the may be swung in one direction or the other, carrying with it the setting lever F. The magnets J, J', which are depended upon to move the armature I are mounted within the cavity of the box-like lever E and their cores y',j, project through the partitions e, e', the latter being formed of non-magnetic material. The magnets are preferably four in number, the two magnets J, J,being arranged to swing the armature in one direction while the magnets J', J', are arranged to swing the armaturein the opposite direction. Provision is made whereby the energizing current may be directed through the magnets J, J, or through the magnets J', J', at the will of the motorman or other person on the approaching car and for this purpose the pairs of magnets are con nected respectively to contact strips K, K', which are fixed in the road-bed near the inner side of the rails A, A, or to contact' strips k, k', supported above the road-bed, as shown in Figs. l and 9 respectively, in position to be struck by contact makers carried by the car.

For the purpose of tilting the lever F to release its notched plate f2 from the tooth js before each operation I have fixed upon the rear end ofthe lever an armature f4. Below the armature f4 and in close proximity thereto I have secured to the coresj and]` of the adjacent magnets J, J', an extension piece f5 which is magnet-ized with either core when the current passes through the coils of its magnet and therefore attracts the armature f4 and tilts the lever F sufficiently to release it; from the tooth f3. The armature f4 is approximately thelength of the extension piece f5 and is therefore attracted whether the magnet J or the magnet J' is energized.

Upon the rear end of the box leverE is pivoted a bent -lever f, whose upper and longer arm stands in proximity to the end of the lever F, while the shorter arm has pivoted` thereto a rod f7 which projects through the casing C near the rail, whereby, as the car approaches, the rod f7 is depressed and the longer arm of the lever f6 is caused to strike the rear end of the lever F and swing its forward end under one of the pins, whereby the switch may be shifted. This device permits the switch to be operated in one direc tion by a car not provided with `circuit closing devices, the rod f7 being so placed as to be operated only by a wheel having an extra wide tread.

-Contact with the strip K or with the strip K' is made from a contact point carried by the car, as before stated. Such contact point might be a xed plate or brush but I prefer the arrangement represented in Fig. 2. In this arrangement two bolts L, L, are supported dametrically opposite each other on the inside of the wheel M of the car, the bolts being insulated from the wheel and forced outward by springs Z, Z. The two bolts are connected by a wire fm and upon the truck frame M' is secured a spring contactplate m in position IIO stefisa to be rubbed by the end of one of the bolts L, L, as the wheel rotates. The contact plate'K or K' being sufficiently long to insure the contact therewith of one or the other of the bolts L, L, the circuit will be completed from thel contact plate m to the contact K or K and thence to the magnets J, J, or J',J', whenever the car passes over the contacts K or K', and the energization of one set of magnets or the other will depend upon the condition of the circuit in advance ofthe plate m'.

As the invention is particularly intended for application to electric trolley railways the circuit from the magnets J, J, and J', J', will ordinarily be completed by connection to the rails A, A, or to the return wire of the`circuit if one be used. If the generator, however, is carried on the car the circuit might be conveniently completed from the magnets to the rails and thence through the wheels and framesecured in convenient position to the dashboard of the car.

As represented in Figs. 10 and 11, I prefer motorman may know that the other deviceshave operated properly to set the switch. The conductor n which supplies the current necessary for operating the switch is ledfrom the source of supply, whether the same be an independent generator or a tap from the trolley wire, and is connected to a suitable binding post n', thence through the electric indicator O (which is represented -as a bell) to a fixed point p. The movable switch P is preferably secured upon thecover of the box and is preferablyy pivoted upon the point p. Other contact points r and lr are also iixedon the cover of the box and are respectively connected through contact devices r2 and r3 fixed in the body of the box and conductors r4 and T5, to the contact plates m,.m, hereinbefore referred to. By setting the switch P upon one or the other of the contacts 1" and r the current may be directed, through the described connections, to either set of magnets J, J, or J', J', and thesetting lever F thereby swung to one side or the other to cause the movement of the switch tongue A3 in the required direction. y

It is obvious that the connections for controlling the movement of the switch mightbe made overhead, as well as at the surface of the road-bed andan arrangement for this purpose is represented in Fig. 9. The switch P is connected as before to the source of supply of the actuating current and the contacts r and r are respectively connected by conductors r4 and 'f5 and S and S' to contact brushes s and s' which are carried by the trolley pole T and are adapted to'be brought in contactV with contact strips k, lc', which are supported overhead by one of the poles U which support the trolley wire and are thence connected by suitable conductors s2, s3 to the magnets J, J, or J', J', as before.

In some cases the trolley pole T is swung upon its vertical axis many times in the same direction so that it would not be feasible to connect the conductors r4, ri' directly to the pole. Accordingly I have providedmeans, as represented in Figs; 12 and 13, whereby the trolley pole may be swung rapidly in the same direction without affecting the conductors. At the base of the trolley pole are secured two semi-circular stripst, t', which are connected respectively to the conductors S and S' before referred to. Spring contacts?, t3 are secured to the supporting frame-work of the trolley pole and bear upon the semi-circular strips t and t', being respectively connected tothe conductors r4 and 1"5.

In describing the mode of operation of the improved devices, let it be assumed that the switch-tongue A3 is in the position represented in Fig. l, that the box-lever E stands as shown `in Fig.' 2, and that the lever F occupies its middle position as represented in Fig. 4. If the motorman of the approaching car desires tothrow the switch-tongue Asin the oppositey direction he shifts the electrical switch P so that the current is completed through the magnets J', J. The lirst effect of the passage of the current through these magnets is to magnetize the extension f5 of the common pole piece and thereby to attract the armature f4 on the rear end of the lever B and to tilt the said lever vertically far venough to raise the notched plate f2 from engagement with the teeth f3, thereby leaving the lever F free to swing laterally. The magnets J', J', acting upon the armature I, swing the lever F from its middle position represented in Fig. 4 to the position represented in Fig. 5, in which the shoulder of the plate f2 stands immediately below the pin d', the horn f passing over said' pin. As the car comes nearer its wheel strikes the pin E' (Fig. 2) androcks the box-lever E from the position shown in Fig. 2, raising its forward end with the plate f2. The shoulder of the said plate-f2 strikes the pin dof the double arm D and throws it up, thereby oscillating the shaft B' and, through the arm B, throwing the switch tongue A3 from the position shown in Fig. l, thereby permitting the car to pass on in the required direction. As soon as the wheel of the car leaves the pin E' the forward end ofthe box lever E drops doWn,-owing to its greater Weight, and carries with it the lever F and the plate f2. As the plate]c2 begins to descend the hornf' strikes upon the pin d and slides upon the same giving the lever F a sufficient impulse laterally to carry it back to its middle position in which it rests until it is shifted again. Should the Vswitch tongue A3 be already in its required IIO position it will not be necessary for the motorman to complete the circuit of one set of magnets or the other, but should he do so the lever F will be released and shifted laterally as before and the box lever E will be tilted as before. This time, however, the arm D being already in the proper position the hornf orf may either be arranged to strike laterally against the corresponding pin d or d so that the lateral shifting of the lever F is checked, or the horn is carried under the pin and, rising against the same, carries the plate f2 farther to one side so that the pin is finally received in the recess between the two horns and breakage is prevented. Then, after the car has passed, the platefz will drop back without being restored to its middle position and at the next action of the mechanism will either be in proper position or will be swung as before to such position. lf a car equipped, not with the electrical setting devices, but with a wheel having a broader tread should approach the rod f7 will be depressed, thelever F will thereby be swung in the proper direction and the tilting of the lever E through the pin E be effected as before. The completing of the circuit through the proper set of magnets J, J, or J', J', by the shifting of the electrical switch P will be effected th rough the described connections in a manner already explained and not requiring further description herein.

It will be apparent that the circuit closing devices on a given car might be set so as to throw each switch in a given direction as it is approached by the car, the switch P being then dispensed with, and likewise different cars might be equipped with circuit closers fixed in different positions in order that cer tain switches maybe operated, the contact strips connected with the dillerent switches being correspondingly placed. It will also be obvious that various other modications of various portions of the devices represented in the drawings and described herein might be made without departing from the spirit of my invention.
