APPARATUS FOR HANDLING MAIL-POUCHES.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed May 29, 190"?- Serial No. 376,329.

To all whom it may concern:

Be it known that I, JOHN MARHANKA, a citizen of the United States, residing at Crothersville, in the county of Jackson and State of Indiana, have invented a new and useful Apparatus for Handling Mail-Pouches, of which the following is a specification.

This invention relates to improvements in apparatus for handling mail pouches in connection with trains or other vehicles while in motion, and it has for its object to provide an improved apparatus of this character wherein the pouches are discharged from the postal car to a stationary receiving device, and simultaneously delivered from the latter to the postal car, preventing the pouch getting under the train and the postal matter thus destroyed, as sometimes happens, and the delivering and receiving devices are capable of being readily reversed in order to adapt them to the direction in which the train is moving, enabling the same apparatus to be employed for trains moving in both directions, the pouches being so supported on the car and the station ary crane that they will be positively received by the respective receiving hooks and accidental loss of the pouches is not liable to occur.

To these and other ends, the invention comprises the various novel features of construction and combination and arrangement of parts, which will be hereinafter more fully described, and pointed out particularly in the claims appended hereto.

In the accompanying drawingsz Figure 1' is a perspective view of mail handling apparatus constructed in accordance with the present invention, the apparatus being shown in condition for delivering a pouch from a postal car and one from the stationary crane. Fig. 2 represents a horizontal section through a portion of a mail car showing the relative arrangement of the movable crane, the dotted lines indicating the position of the crane in discharging the pouch. Fig 3 represents a rear elevation of the crane on the car, showing it in readiness to receive a pouch. Fig. 4 represents a sectional view of one of the pivot members for the crane on the car. Fig. 5 is a detail view of one of the pouch shields. Fig. 6 is a detail view showing the manner of mounting the receiving hook on the car.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The apparatus shown in the presentembodiment of the invention is so constructed that the services of an attendant during the delivering operation of the pouches from passing trains is unnecessary, so that liability of the employees to injury is minimized, and the apparatus consists, in the present instance, of a relatively stationary crane having a receptacle to receive pouches and suitable devices cooperatively arranged therewith for discharging the pouches from the crane on the car, and devices on the crane for delivering a pouch to the car, the stationary crane being reversible in order to accommodate it to trains passing in two directions, and the relatively movable crane and receiving hook on the car is also reversible in order to accommodate it to the direction of movement of the train, and is adapted to cooperate with the appliances for supporting and causing the delivery of the pouch as the train passes the stationary crane.

In the present instance, the stationary crane is composed of a standard 1 having a pair of divergently ar ranged legs 2 rigidly supporting it in vertical position, the lower end of the standard and the ends of the legs being firmly attached to a suitable support, such, for instance, as a station platform, and the top of the standard may be surmounted, if so desired, by a lamp or other signal 3 which serves to aid the postal clerk in locating the stationary crane. Mounted to turn in a horizontal plane about this standard as an axis in an adjustable arm which serves to support the pouch receiving re ceptacle and the devices for delivering the pouches thereto and also the devices for supporting the pouch is in position to be taken up by the car. This arm comprises, in the present instance, a horizontal guide 4 having its inner end rigidly attached to a sleeve 5, the latter being mounted to turn about the standard. The inner ends of a pair of guide bars 6 and 7 are also joined to the said sleeve, the guide bars extending parallel to the guide and on opposite sides thereof, and having their outer ends joined thereto by means of the cross pieces 8. The outer portionof the guide 4 cooperates with a bracket 9 which extends upwardly from the diagonal brace arm 14 to a point above the end of the crane arm where it is provided with an eye 10, the brace arm extending in a direction both downwardly and inwardly from the outer end of the guide and connected to the bearing sleeve 5 on the standard. 00- operating with the outer ends of the brace arm and the guide 4 is a standard 15 which serves as a support for the pouch supporting devices of the stationary crane. This standard is provided with eyes or other suitable means for connecting it to these parts and it extends vertically therefrom, its upper end extending through the eye 10 on the bracket 9. A pouch shield 16 is rigidly supported on the outer or free end of the crane arm, which, in the present instance, is semi-cylindrical in shape and has an opening therein toward the outer end of the crane arm, the standard 15 extending through the casing and provided with a pair of pouch supporting arms 17 and 18 which are adjustable about the standard as an axis, whereby they may be offset angularly to either side of the crane arm, the pouches to be taken up by the train being supported on these arms, as will be hereinafter described.

The receptacle for receiving the pouches from the postal car may be of any suitable form, that shown in the present instance embodying a pair of strips 19 of relatively heavy wire or rod arranged parallel and at opposite sides, and a basket-work composed of wire or rope which is semi-cylindrical in shape. This receptacle is supported on the crane arm by means of a pair of brackets 21 and 22, the former having an intermediate portion doubled over the outer ends of the guide 4 and brace arm 14, the bracket 22 having a pair of loops 22 and 22 which cooperate with the parallelv members 6 and 7, a loop 22 being preferably formed on the bracket 22 between the loops described and cooperating with the brace arm 14 to steady the receptacle and prevent its swinging or sagging under the load of the pouches.

The devices on the stationary frame for delivering the pouches into the receptacle embody, in the present instance, a hook 23, which is arranged at an acute angle relatively to the guide 4, that is to say, it extends diagonally relatively to the direction of movement of the crane, its outer end being free and its inner end attached to a slide 24 which is movable longitudinally on the guide 4 in order to permit it to ease the shock or impact caused by the discharge of the pouch, a yielding buffer or recoil check being interposed between the slide for the hook and the crane arm to absorb the shock. The buffer or recoil check employed in the present instance comprises a helical spring 25 attached at its inner end to the sleeve 5 and at its outer end to the slide, the tension of the spring acting normally to move the hook toward the standard and to resist forces tending to move it away from the standard, the inner end of the sleeve 26 of the slide cooperating with the sleeve 5 or any other stationary part of the crane arm as a stop for limiting the inward movement of the slide under the action of the spring and serving to normally retain the delivery hook in proper position relative to the pouch receptacle. The delivery hook is reversible, that is to say, it is adapted to occupy positions on both sides of the guide, the hook being capable of turning in a vertical plane about the guide 4 as an axis, the oppositely arranged parallel members 6 and 7 cooperating with a portion of the hook adjacent to the slide thereon tosupport the hook in operative position at either side of the guide.

The relatively movable crane on the car for supporting the pouch in readiness to discharge into the relatively fixed receptacle comprises, in the present instance, a pair of parallel arms 28 and 29 connected at one end by a cross piece 30. These arms are adapted to operate longitudinally in pivot members 31 of any suitable form secured to the jamb at one side of the door opening when the car is moving in one direction, and to interchangeably fit a pair of similar pivot members 32 at the opposite side of the door opening, these pivot members having vertical axes in order to permit a swinging movement of the crane in a horizontal plane, and, if so desired, the arms of the crane may be of a length suflicient to engage both pairs of pivot members and thus form a closure for the door opening. These crane arms are adapted to receive the usual rings 33 and 34 secured, respectively, to the top and bottom of the pouch, and

also the rings 35 and 36 on the sack discharging cable or other flexible element 37, the latter having snap hooks or other suitable attaching devices 38 and 39 at its ends adapted to cooperate respectively with suitable attaching devices on the pouch, or, if so desired,

the top and bottom rings of the pouch may be utilized as fastenings for the snap hooks of the discharging cable. The rings 35 and 36 on the chain are located some distance from the ends thereof in order that an intermediate portion of the chain may extend between the crane arms toward their outer open ends and the sack may be supported on the crane arms at a point nearer the car so as to provide sufiicient clearance between the pouch and thecrane for the passage of the discharging hook on the relatively fixed crane.

In order to protect the pouch on the car from the rain and wind while it is in position preparatory to delivery, it is preferable to provide a shield, that shown in the present instance comprising a deflector plate 40 having one of its vertical edges rolled to form a sleeve 41 which encircles the connecting portion 30, or it is attached in any other suitable way that may be desired. The advantage of attaching it to the connecting member 30 'is that it will be correctly positioned relatively to the pouch when the supporting arms 28 and 29 are extended through the car door, as shown in dotted lines in Fig. 2, and when these arms are reversed, that is to say, when they are applied to the bearing members at the opposite side of the car door, an inversion of the arms will serve to position the shield so that it will protect the pouch when the car is moving in the opposite direction.

The apparatus shown in the present instance is not only capable of discharging pouches from the car to a relatively stationary crane, but it is also capable of automatically transferring pouches from the stationary crane to the car when the train is in motion, the devices employed in the present instance for accomplishing this purpose comprising a slide bar 42 extending hori zontally across the car door and supported by brackets or other suitable devices 43, and mounted to slide on this bar is a cross head 44 which'carries the receiving hook 45, the latter being attached to the cross head in any desired way and preferably in such a manner that it may be reversed and thus permit it to be used while the car is moving in either direction. In the present instance, a shank 46 of the hook is rotatably mounted in the bearing portion 47 on the cross head, the latter being provided with a squared portion to receive a correspondingly shaped part 48 on the shank of the hook, the shank beyond the squared portion being rounded or reduced and provided at its inner end with an operating handle 49 whereby it may be manipulated. A helical spring 50 interposed between the handle and the cross head serves to normally retain the squared portion of the latter and the hook in cooperative relation, so that the hook will be supported in a horizontal position in readiness to take up a pouch supported on the stationary crane. When it is desirable to reverse the hook, the shank thereof is moved axially of the cross head against the compression of the spring 50, thereby disengaging the cooperating squared portions and permitting the hook to be rotated through half a revolution about the shank thereof as an axis.

In order to reduce the shock due to the impact of the pouch against the hook on the car, it is preferable to provide suitable recoil devices for absorbing the momentum, a pair of helical springs 51 and 52 being employed in the present instance which encircle the slide bar at each side of the cross head and between the latter and the respective supporting brackets at the end of the slide bar.

The pouch to be taken up by the car is also provided at its ends with a pair of rings which are adapted to be slipped upon the supporting arms 17 and 18 from the outer ends thereof, or, if so desired, a supplemental supporting arm 54 that is relatively shorter than the main supporting arms may be employed to receive the upper ring on the pouch, the supplemental supporting arm being also mounted on the vertical standard 15. The pouch to be taken up by the car is also provided with a sling or loop which is composed of a cable or flexible element 55 and it has a pair of loops or rings 56 and 57 thereon which are arranged to engage the ring supporting arms 17 and 18 at points adjacent to their outer ends, so that the intermediate portion of the loop or sling will extend between the outer ends of the arms and in a position that willenable it to be readily engaged by the hook 45 on the car. The shield 16 preferably has its closed side arranged in the direction from which the train approaches, so that the draft produced by the movement of the train will not cause the pouch to be blown from its supporting arms.

In order to support the outer ends of the reversible crane arm and prevent movement thereof during the reception and discharges of the pouches relatively thereto, it is preferable to provide a steadying device which comprises, in the present instance, a pair of substantially parallel vertical members 58 and 59 which are connected by a series of cross bars 60 which may be utilized as a ladder to enable the attendant to place the pouch into the receptacle or shield 16. This steadying device may be either stationary, that is to say, it may be permanently fastenedto the station platform or other support, or, if so desired, it may be attached to the outer end of the crane arm so as to swing therewith. It is shown in the present instance as secured to the platform and detachably locked'to the crane.

In handling mail pouches with an apparatus constructed in accordance with the present invention, the adjustable crane arm on the relatively fixed crane is set to point in a direction in which the train that is to discharge the pouches is moving, and the crane arms of the relatively movable crane are inserted in the pivot members 31, that is to say, those toward the front of the car, and after the rings at the top and bottom of the pouch have been slipped over these arms while the latter occupy the position shown in Fig. 2, and the rings of the cable have been slipped over the outer ends of these arms, the crane is turned about the pivot members into a position similar to that indicated by the dotted lines in Fig. 2. While the crane on the car occupies this position, the intermediate portion of the chain is in line with the relatively fixed discharging hook on the stationary crane, and as the postal car passes the latter, the discharging hook will engage the intermediate portion of the cable and the relative movement of the discharging and receiving parts of the apparatus will serve to draw the rings of the cable and pouch longitudinally toward the outer ends of the crane arms on the car. The angular position of the crane arms on the car relatively to the direction of movement of the train will cause an outward move- .apertures 10 and 11 of the sleeve and standard, respecment of the pouch as it disengages from the crane arm, and this will operate to swing it into a position above the receptacle in rear of the discharging hook when the cable attached to the pouch has been engaged thereby, and the weight of the pouch will serve to deposit it into the receptacle. The recoil or impact produced by the sudden arresting movement of the pouch is absorbed by the check or buffer 25, so that damage or injury to the pouch or its contents isavoided and the strain on the stationary crane is minimized.

When the train is moving in the opposite direction to that describedabove, the adjustable anns on the stationary crane may be adjusted accordingly by operating the lever B to withdraw the locking pin 9 and the tively, the crane arm being also then turned in a horizontal plane through an angle of 180. The crane arm will then occupy a position on the opposite side of the standard and pointed in the direction of movement of the train, and by rotating the discharge hook 23 about the guide 4 as an axis, its position will be reversed and it will be .directed toward the path of the train, a portion of the hook cooperating with the member 7 to support the hook in operative position. The crane on the car is applied in this case to the pivot members 32 at the opposite side of the car and swung at the proper angle to carry the discharge chain into line with the discharging hook on the stationary crane.

The foregoing is a description of the operation of the devices which serve to transfer the pouch from the car to the stationary support, and, in the present instance, the apparatus is capable also of transferring the pouch from the stationary support to the postal car while the latter is in movement. and without interfering with the operation of discharging the pouch from the car, the pouch to be taken up by the car being introduced into the casing or shield 16 and the loop thereon having its supporting rings 56 and 57 slipped over the outer ends of the supporting arms 17 and 18, the latter having been previously turned about the standard 16 as a center, so that they are offset from the crane arm in a direction toward the crank. When these arms are so adjusted, the intermediate or looped portion of the cable attached to the pouch will be in the path of movement of the re ceiving hook 25 on the car, and as this hook passes the stationary crane, it will withdraw the pouch from the shield or casing after the pouch supporting arms on the car have passed it, the pouch swinging behind these arms and into the car door. The shock or momentum produced by the impact between the pouch and the re- 1 15 ceiving hook on the car is absorbed by the recoil springs.

The reversible feature of the apparatus adapts it especially to service on single track roads where the trains move in both directions on a single track, but it may be applied also to double track roads by mounting the stationary crane at a point midway between the two tracks, and the apparatus is capable of such a use for the reason that no parts of the apparatus project unduly at either side thereof, the pouch receptacle having its support arranged centrally thereon in order that the pouches may be deposited into either side thereof according to the direction of movement of the train.

Mail delivery apparatus constructed in accordance with the present invention insures a positive transferring of the pouches from the postal car to the relatively fixed receiving devices, and vice versa, so that the i pouches cannot :be dropped or otherwise permitted to fall and thus become lost or destroyed under the running gear of the train, and the operation is performed automatically, so that not only is injury to bystanders prevented, but, as the apparatus does not require the services of an attendant at the rocei ving devices, injury oi the employees is not liable to occur.

Moreover, the reversible feature enables the same apparatus to be adjusted to operate with trains moving j in both directions, thus economizing in the cost and maintenance of the apparatus and reducing the number oi obstructions along the track, and, furthermore, the 1 novel mode of supporting the pouches not only insures 1 its positive delivery, but it obviates the necessity of tying a strap about the center of the pouch, so that full pouches may be handled with the apparatus, and in- 3 jury to the pouches is minimized for the reason that the receiving hooks do not engage the body of the pouch, and this feature may be employed in connnection with apparatus of various forms, the cable or flexible member attached to the pouch being adapted to codperate with the receiving hooks employed generally on postal cars. .7
