MAIL-POUCH RECEIVING AND DELIVERY APPARATUS FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented. Feb. 25, 1908.

Application filed December 6. 1907. Serial No. 405.393.

T 0 all whom it may concern:

Be it known that I, CHAUNoEY W. BROUGHTON, a citizen of the United States, residing at Carlton, in the county of Dekalb and State of Illinois, have invented certain new and useful Improvements in Mail-Pouch Receiving and Delivery Apparatus for Railway-Cars, of which the following is a full, clear, and exact specification.

This invention relates to apparatus for delivering a mail pouch from a mail car or receiving a mail pouch from a station while the car is passing, and it has for its primary object to provide improved and simple means whereby such pouch may be either received or delivered and held in place after its reception or delivery by the attraction of an electro magnet.

With a view to the attainment of these ends and the accomplishment of certain other objects which will hereinafter appear, the invention consists in the features of novelty which will now be described with reference to the accompanying drawings and more particularly pointed out in the claims.

In said drawings-Figure 1 is a plan view of my improved apparatus on the car, showing the car in .plan section and illustrating both the receiving and delivery devices in their running position, that is, in the position they assume while passing all points eXcept ing the station where the mail pouch is to be either delivered or received. Fig. 2 is a similar view of one end of the car showing the receiving and delivery devices in their receiving and delivery positions. Fig. 3 is a similar view showing the receiving and delivery devices drawn into the car. Fig. 4 is an end elevation of the car, partly in vertical section, showing its relation to the delivery and receiving devices at the station. Fig. 5 is a partial plan thereof, Fig. 6 is a detail side elevation of the mail pouch and its armature, showing its relation to the station receiving magnet, and Fig. 7 is a plan of the track circuits.

Like signs of reference indicate like parts throughout the several views.

According to this invention, the mail pouch to be delivered from the mail car to a station is carried on a suitable delivery arm mounted upon the car and suspended therefrom by rings or other suitable devices which will permit the pouch to readily slip off when engaged by a superior force, This delivery arm may be hinged or pivoted, on the car so as to be thrown out into position to bring an armature on the mail pouch into engagement with an electro magnet mounted at the station so that when the armature strikes the magnet, the impact will release it from the delivery arm and it will remain in the grasp of the magnet at the station. On the other hand, should it be desired to deliver a pouch from the station to the car, it will be held by a delivery arm at the station similar to the delivery arm on the car, and will be engaged and picked up by an electro magnet carried on the car. I

The invention also contemplates automatic means whereby the electro magnet on the car will be energized when it is in its outer position for receiving and carrying the pouch, and will be denergized when turned into the car, so as to automatically permit the pouch to drop.

The invention further includes automatic means for energizing the electro magnets both on the car and at the station by the current of the storage batteries usually carried on the car for lighting purposes.

In the side walls 1 of a car are mounted doors 2, 3, which are adapted to open inwardly in the manner shown in Fig. 3. In each of these doors, on the hinge bar or pintle 4 thereof is mounted a pivoted support or head. In the door 2 this head is shown at 5, and in the door 3 it is shown at 6, and each consists of a member rotatable a limited distance independently of the door, provided with two sockets 7, 8 arranged one above the other. In these sockets of the head or support 5 are arranged the cores or pole pieces 9, 10 of an electro magnet, which are held removably in the sockets by set screws 11 or other suitable means so that they may be readily removed for the purposes which will be presently described, the head 5 constituting a magnetic connection between the pole pieces or cores 9, 10.

The outer ends of the pole pieces or cores 9, 10 are designed to receive the mail pouch and carry it preparatory to its delivery into the car, and in order that they may be better adapted for this purpose, they are bent downwardly and arranged in substantially the same vertical plane at right angles to the side of the car, when the cores or pole pieces 9, 10 are in the extended position shown in Figs. 2 and 4, so that an armature 12 attached to the mail pouch 13 by ring or support 14 may engage both of the pole pieces 9 and 10 and be attracted thereby as the armature hangs on an arm or support 15 at the station in a position at right angles to the line of travel of the car. When the armature is struck by the pole pieces 9, 10 it is slipped from the end of the arm 15, which is supported by a vertical pivoted head 16, permitting the arm to swing in a horizontal plane. This gives the magnetic pole pieces an opportunity to attract the armature 12 with sufficient force to hold it after it slips from the arm 15 and is thus carried by the pole pieces until they are eventually turned within the car in the posi tion shown in Fig. 3, where the circuit through the winding 17 of the magnet is automatically broken and the pouch allowed to drop within the car, as will be presently explained. As soon as the car passes the station where the pouch was received, the magnetic bars 9, 10 spring automatically to the position shown in Fig. 1, so as not to strike against objects along the road. The means for accomplishing this will now be eX- plained. When the doors 2, 3, are not otherwise restrained, they are closed by means of springs 18, 19 respectively secured thereto by means of cables 20, 21 passing around pulleys 22, 23, or by any other suitable means, and the heads 5, 6, when not otherwise restrained, are turned outwardly into the position shown in Fig. 2 by means of springs 24, 25 respectively attached to lugs 26 thereon, by means of cables 27 passing around pulleys 28, 29. Both of the heads 5, 6, are also attached to one end of a bar 30 by means of cables 31, 32 passing around guide pulleys 33 and attached to lugs 34 on the sides of the heads opposite the lugs 26, so that the cables 31, 32 will pull the heads 5, 6 inwardly against the resistance of the springs 24, 25. The cables 31, 32 are attached to two automatic switches respectively which are also connected to the bar 30 by cables 35, 36 passing around suitable guide pulleys 37, 38, and which automatic switches serve to close and energize the circuit through the car magnet coils 17 when supported by either of the heads 5, 6, as long as the car magnet occupies a position outside the car, but to break such circuit, as soon as the car magnet comes within the car to the position shown in Fig. 3. It might be here stated that the heads 5, 6 are capable of supporting and operating either the magnetic bars 9, 10, or a pair of plain arms 39, 40, which serve merely to support the pouch as shown on the right in Fig. 4, preparatory to delivery from the car to the station. Consequently, the mechanism of the two sides of the car are substantially duplicates of one another with the exception of these arms 39, 40 and the magnetic bars 9,

10, but for the sake of simplicity, the circuit wires 41, 42 for the coils 17 have been shown on one side only. i

The automatic switches to which the cables 31, 32 are connected, and which have just been referred to, each consists of two sliding contacts 43, 44, and at each end of each of these contacts is a strip of insulation 45, 46. These sliding contacts and strips of insulation are shown as secured together in the form of parallel bars whose ends are connected by cross-heads 47, 48,to the cables 31, 32 at one end and 35, 36 at the other end. Arranged to be engaged by the sliding contacts 43, 44 and the insulations 45, 46 are two stationary contacts 49, 50, which are insulated from each other and respectively connected to conductors 51, 52 having connection with the positive and negative poles of storage battery 53 by conductors 54, 55. With this arrangement it will be seen that when the head 5 is pulled outwardly into the position shown in Fig. 2 by the spring 24, or when pulled to the running position or partially into the car, as shown in Fig. 1, the magnetic windings 17 will be energized by the current passing from the positive pole to the contact 49 and from the contact 49 to the contact bar 43, and thence into contact wire 41, which is connected to contact 43, thence to one of the windings 17, whence it passes into the other winding 17 and returns to contact bar 44 by the wire 42, thence into contact 50 and back to the negative pole of the storage battery 53 along the conductors 52, 55. Should the contact bars 43, 44 be pulled into the position shown in Fig. 3, which results from pulling the magnet and door 2 into the car, as shown in that figure, the circuit through the conductors 41, 42, leading to the windings 17, would be broken by carrying the contact bars 43, 44 away from the contacts 49, 50, which would then be engaged by the insulations 46 alone, thus breaking the circuit through the magnetic windings and permitting the pouch to fall into the car. The car doors 2, 3 remain in their closed position until the magnetic arms or bars 9, 10 attempt to move inwardly beyond. the position 'shown in Fig. 1, when parts of the heads, 5, 6, come against the doors 2, 3, and open them inwardly against the resistance of their springs 18, 19, the heads 5, 6, being mounted in recesses 56 in the doors, which permit the heads to have a limited movement independently of the doors.

The inward movement of the heads 5, 6 from their extreme outer positions shown in Fig. 2 to their intermediate position shown in Fig. 1 is effected automatically by a magnet 57 or other suitable electro'responsive device mounted upon the car, as soon as the car passes the station where the mail pouch is to be received. The magnet 57 is arranged to influence or attract an armature 58 secured to the end of the bar 30, so that when the bar 30 moves towards the left, or is attracted by the magnet 57 the two cables 35, 36 will be pulled in a direct-ion to pull the heads 5, 6, inwardly, the cables be ing passed around a pulley 59. The terminals of the magnet 57 are connected by conductors 60, 61 to insulated contacts 62, 63. When the car is between stations, these contacts 62, 63 are held in communication with the positive and negative poles of the battery by movable switches or contacts 64, 65, which are permanently in engagement with the battery contacts 66, 67 to engage the contacts 62, 63 only when the movable contacts 64, 65 are pulled back by springs 68, 69 after the station is passed. While passing a station, the movable contacts or switches 64, 65 are thrown out of engagement with the contacts 62, 63 by rails 69, 70 arranged on the road bed, or other convenient place at the station and adapted to engage the lower ends of the pivoted levers 71, 7 2 carried by the car and projecting upwardly thereinto and carrying the movable contacts 64, 65, the rails 69, 70 being provided with outturned ends 73, 74 to insure the engagement thereof of the levers 71, 72. Consequently, it will be seen that when the car is not at a station, the movable contacts 64, 65 will be in engagement with the contacts 62, 63, and the circuit will be closed through conductors 60, 61 and the magnet 57, thereby causing the latter to attract the armature 58 and pull the sliding bar 30 down to the position shown in Fig. 1, holding the magnetic arms 9, 10 out of the way of objects along the road, and at the same time keeping the same energized through the connections and circuits before described. As soon as a station is reached, however, the levers 71, 72 engage the rails 69, 70 and the circuit through the magnet 57 is broken, whereupon the springs 24, 25 at once return the parts to the position shown in Fig. 2, where they remain until the station is passed and the magnet 57 again becomes energized, pulling the parts back to the position shown in Fig. 1. Should a mail pouch have been received by the pole pieces 9 10, the attendant within the car may now move the parts into the position shown in Fig. 3 for delivering the pouch into the car by closing a hand switch 75 and energizing the magnet 76, or other suitable electro responsive device arranged to impart a still further pull to the sliding bar 30, which has an armature 77 arranged to come within the magnetic field of magnet 76 after the bar 30 has been pulled 'to the position shown in Fig. 1 by the magnet 57.

The terminal wires 78, 79 of the magnet 76 are connected to the knives of the switch 75, and the clips of this switch are connected to the battery wires 54, 55 by conductors 80, 81,

so that when the knives of the switch 75 engage their clips, the magnet 76 will be energized and the bar 30 will be pulled still further towards the left, causing the doors 2, 3 and the heads, 5, 6 to move into the car, as shown in Fig. 3, and at the same time break the circuit through the magnet windings 17 by carrying the contact bars 43, 44 out of contact with the stationary contacts 49, 50. In order that the bar 30 may be thus still further attracted and moved towards the left by the magnet 76 after the armature 58 has been attracted by the magnet 57, the armature 58 is pivoted at 82 to said bar 30, and in order that the attraction of the armature 58 by the magnet 57 may be effective on the bar 30, the armature 58 is provided with a shoulder 83 arranged to engage the bar 30 when the armature is pulled in one direction, the armature being held in position to be attracted, when the magnet 57 is influenced, by a spring 84, permitting the armature 58 to yield when the armature 77 is attracted by the magnet 76. The parts remain in the position shown in Fig. 3 as long as the hand switch 75 is maintained closed, but as soon as the hand switch is opened, the magnet 76 becoming energized, the springs 18, 24 and 19, 25 connected with the heads 5, 6, and doors 2, 3, pull the parts back to the position shown in Fig. 1 and the spring 85 returns the sliding bar 30 to the position shown in that figure, where the armature 58, under the influence of the magnet 57, will hold it until the circuit through the magnet 57 is again broken automatically as a station is approached.

In order thatthe mail pouch 13 may not be accidentally displaced from the station arm 15, it is preferable to provide a guard finger 86, which is pivoted to the arm 87 carried on the head 16 with the arm 15, and held down against the arm 1.5 by a spring 88 or other suitable means. The arms 15 and 87 are held in a position at right angles to the line of travel of the car, so as to present the armature 12 to the pole pieces 9 10 by any suitable means which will yield when the pole pieces strike the armature. The head 16 being mounted on a vertical pivot, the desired end may be accomplished by attaching the head to a cord 89 which passes downwardly between a pair of pulleys 90 on post 91, and is attached to a spring 92 which serves to return the arms 15,87 to their position shown in Figs. 4 and 5.

As it cannot always be determined in advance which side of the car shall be utilized as the delivery side for delivering the pouch from the car to the station, it is desirable, as 5 before suggested, to make the magnetic core pieces 9, 10 interchangeable with the plain arms 39, 40, so that either head 5, 6 be used for carrying the core pieces on the arms 39, 40. These arms 39, 40 are or may be counterparts of the arms 15, 87, the lower 1 ing a mail pouch preparatory to being delivarm 10 being adapted to support the mail pouch 13 to be delivered by rings or hooks 93, like the rings or hooks employed on the armature 12 of the mail pouch 13, and the arm 39 being provided with a guard finger 94 pivoted thereto and held against the arm 40 by a spring 95 to prevent the mail pouch 13" which is about to be delivered to a magnet at the station, from being accidentally dis placed.

The magnet at the station for receiving the pouch from the car may be inserted on either side of the track or road, and may be a counterpart of the magnet carried on the car and interchangeable with the arms 15, 87, if desired. To that end a post 96, like the post 91, is mounted at the side of the track opposite that on which post 91 is mounted, and this post 96 may be provided with a head 97, like the head 16, for supporting either the arms 15, 87, or a pair of magnetic core pieces 98, 99. It will be seen that the heads 16, 97 are provided with sockets 100, into which either the plain arms 15, 87, or these core pieces, 98, 99, may be inserted and secured by set screws 10]., or other suitable means. The core pieces 98, 99 are provided with spools or windings 102, and. these are in circuit with the rails 69, by means of wires or conductors 103, 104. Consequently, when the car reaches a station, the lower ends of the levers 71, 7 2, which will act as brushes, contact with the rails 69, 70 and communicate the current of the storage battery 53 on the car to the magnet windings 102 at the station, because at this time the contacts 641, 65 carried by the upper ends of the levers 71, 72 are shifted out of engagement with the contacts 62, 63, and consequently cut out the magnet 57 and direct the current of the battery 53 to the windings 102, thereby energizing pole pieces 105 of the cores 98 and enabling the magnet at the station to attract the armature carried by the arm 40 on the passing car and to hold the pouch. suspended until the car passes, when the interruption of the current allows it to fall to the ground.
