RAILWAY IVTAIL-I-IANDLINGr APPARATUS.

Specification of Letters Patent.

Patented Dec. 7, 1909.

Application filed February 1, 1909. Serial No. 475,442.

To all whom it may concern:

Be it known that I, NEILL H. CAMPBELL, a citizen of the United States, residing at Bmghamton, in the county of Broome, in the State of New York, have invented new and useful Improvements in Railway Mail- I-Iandling Apparatus, of which the followlng, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in railway mail handling apparatus and refers more particularly to the combination of a receiver and delivering apparatus, the latter being adapted to receive and automatically retain the mail bag and is provided with means coacting with a portion of the receiver for releaslng the mail bag and enabling the same to be deposited by its momentum and gravity into the receiver.

My main object is to provide a combined delivering and receiving apparatus by which the mail bag may be suspended from the neck and automatically deposited into the receiver without liability of damaging the bag or its contents.

The mail bag is suspended by the neck between suitable jaws of the delivering apparatus on the moving car, the jaws being held in their closed position upon the neck of the bag by a movable detent having a trip arm adapted to contact with a portion of the receiver while the car is moving for the purpose of causing the jaws to open to release the bag and allow it to discharge by its own momentum and gravity into the receiver which is stationary and located in suitable proximity to the moving car in the path of the trip arm and bag.

Other objects and uses relating to specific parts of the delivering device and receiver will be brought out in the following description.

In the drawingsFigure 1 is a perspective view of the receiver and delivering apparatus, the latter being shown as operatively mounted in the door of a mail car ready to deliver the mail bag into the receiver which is shown in its receiving position. Fig. 2 is an enlarged lengthwise vertical sectional view through the receiver and supporting frame shown in its closed position after the mail bag has been delivered thereinto. Fig. 3 is an elevation partly in section of the main portion of the delivery device. Fig. 4 is a top plan of the detached delivering apparatus showing the upright supporting standard in section and the aws in their closed position. Fig. 5 is a sectional View through the swinging support for the adjusting rod for the delivery device showing said adjusting rod in elevation. Fig. 6 is an elevation partly in section and partly broken away of the upright supporting standard and its retaining sockets. Fig. 7 is a detail View of intersecting portions of the rope which form the cage or basket receiver.

The receiver preferably comprises a swing ing cage l and a swinging closure -2- therefor, both of which are mounted in and upon an open rectangular supporting frame -3, the latter being supported at the desired height relatively to the car upon upright legs or standards --4: which rest upon the ground or other suitable foundation. It is evident, however, that any other suitable support, capable of holding the receiver in proper relation to the delivering device in the car, may be substituted. It is also evident that the basket may be hung upon any convenient support so long as it is capable of swinging to and from a vertical and horizontal position. It is evident, however, that although I have described the frame 3- with the cage 1 and cover 2- as removable bodily from the platform 4, the effect in reversing is the equivalent of mounting the latter device upon a revolving support.

The cage l consists of an open rectangular frame 6- preferably of angle or channel iron and a flexible netting 7 made of intersecting ropes fastened together at their intersections and properly anchored to the frame 6 preferably by passing the ends of the ropes through apertures and having crown knots to prevent withdrawal of such ropes. These ropes are usually made of French cable-made hemp or other suitable material capable of retaining a more or less permanent form when the frame 6 is adjusted for use,that is the ropes are arched or projected some distance beyond the rear of the frame 6 to form a flexible basket or cage to receive the mail bag when released from the delivery device hereinafter described.

The open frame 6, which is quite rigid and of ample size to receive the mail bag, is hinged or pivoted near its lower or front end at -8 to the front endof the main supporting frame 3- and is preferably of the same form and size as the main frame, the pivot or hinge --8 being located equidistant from the corresponding ends of the frames 3- and 6- so that when the frame 6 is in its closed position its sides and ends lie in close proximity to the sides and ends of the main supporting frame --3, the rear end of the latter forming a limiting stop or abutment with which the corresponding. end of the frame 6 engages when forced to its closed position by the impact of the mail bag and trip arm therewith. The greater portion of the receiving basket or cage 1 therefore projects some distance above the top of its supporting frame 3 with the open side of the frame 6 in alinement with and facing the mail bag when the latter is suspended upon the car for delivery.

The swinging movement of the main re= ceiveror basket 1 is limited to a vertical position by means of one or more limiting stops 9 which in this instance constitute the upturned ends of spring arms 9, the latter being secured to adjacent legs or upright parts 5 of the main supporting frame 3 and are spring-tensioned upwardly so as to automatically position the stops 9 in the path of the adjacent ends of the disk supporting frame -6 as the latter is swung upwardly to a vertical position.

The swinging closure 2-' comprises a substantially rectangular open frame.10 (preferably of angle iron) and a rope netting 11 of comparatively coarse mesh united at the sides and ends of the frame 10- except at the end which is hinged to the main supporting frame 3 where the lengthwise ropes are continued across the adjacent end bars of theframes 3 and 10- and attached to the corresponding end of the swinging frame -6 of the basket 1.

The swinging frame 10- and its netting 11 constitute what may be termed a supplemental receiver forming an extension of the end of the frame 8 in which the basket 1 is hinged, said supplemental frame being adapted to swing through an arc of substantially 180 from a horizontal position at one side of the main supporting frame 3 to another position substantially coincident with that of said main supporting frame where it serves to cover a portion of the open side of the has ket. This supplemental receiver 2-- is connected intermediate its ends by cables or ropes 1-2- to the intermediate portions of the sides of the basket frame G leaving ample intervening space between the cables for the reception of the mail bag, said cables serving to limit the downward swinging movement of the supplemental receiver,

when the basket 1 is swung to its vertical position or adjusted for use and at the same time causing said supplemental receiver to fold over upon the frame when the basket is forced to its down position by impact of the trip arm of the delivery mech- 1 anism and mail bag therewith.

The delivery mechanism previously referred to is supported upon an upright bar 13, which is located in the door way 14 of a car 15- and comprises a pair of intersecting levers or jaws -1($- fulcrumed upon an upright supporting bar 17- and having their rear ends movable 0 toward and from each other for grasping and releasing the neck of a suitable mail bag -l8-. the forward ends of said jaws being provided with shoulders -l9 which are normally engaged by a bifurcated detent 20 for holding the mail bag between the gripping jaws of the levers 16- or upon the neck of the mail bag 1S when the delivery device is adjusted for delivering the mail bag to the receiver --1.

The detent 20- is made in the form of a lever fulcrumed at 21- upon a supporting bracket 2Q which is also mounted upon the upright support 17 and is reinforced or braced by suitable braces 23 and secured to the forward end of the bracket 22 and to the upright support 17 as best shown in Fig. 1. This detent is provided with a trip arm 2l extending some distance beyond the fulcrum 21- and when the delivery device is adjusted for use for delivering the mail bag into the receiver, the trip arm -2l projects into the path of the upper portion of the frame 6 of the basket 1. It is now clear that as the car is moving in the direction of arrow X, Fig. 1, the trip arm 24.-- will encounter the upper end of the basket frame (3 of the receiver thereby tripping the detent -20 and allowing the gripping jaws of the levers 1(3- to be opened by the action of a spring 25 as best seen in Fig. 5.

The mail bag is suspended from the gripping jaws of the lever -16- in alinement with the position of the open side of the receiver l so that as it is released by the opening of the gripping jaws or levers 16, its momentum and gravity will carry it directly into the open side of the receiver and the force of impact of the mail bag together with that of the trip arm 24*- against the receiver will rock the receiver from its vertical position to its horizontal position with the bag therein. This rocking of the receiver from its vertical to a horizontal position will cause a corresponding movement of the supplemental receiver 2- through the medium of the cables 12, said supplemental receiver serving to trap the mail bag in the basket 1 after the latter has been forced to its down position with the mail bag therein and at the same time it afi'ords a more positive trapping of the mail bag in the receiver by reason of the factthat as soon as the tilting receiver 1 is rocked from its operative position by the force of impact of the mail bag and detent therewith, the extension or supplemental receiver 2 is immediately thrown toward and partially closes the open side of the receiver -1 to prevent rebound of the bag therefrom.

The upright supporting arm -17 is mounted upon a horizontal extension 28 which telescopes with and passes through a horizontal tubular support 29, the latter being mounted directly upon the upright support 13. The inner end of the horizontal support -28- is provided with a handle 80 by which it may be adjusted to properly position the delivery device relative to the receiver.

The upright supporting rod 13 is extensible and removably supported in the upper and lower sides of the door opening and for this purpose is composed of telescoping sections clamped together by a set screw 31, the upper end of the upper section being stepped or loosely seated in a socket 32 in the upper side of the door opening while the lower end of the lower section is loosely seated or stepped in a socket 33 in the bottom of the door opening as best seen in Fig. 4, the entire support being rotatable in said socket-s to allow the delivery device which is mounted thereon to be rocked by hand entirely within the car or adjusted so as to support the mail bag and trip arm of the detent in position to engage and deposit the mail bag into the receiver. As the trip arm 24 is forced from its normal position by impact with the upper end of the receiver its free end is impinged between a pair of spring jaws -36 which operate to frictionally hold said detent in its inoperative position. By loosening the set screw 31, the lower section of the support 13 may be elevated out of the socket 33 thereby permitting the withdrawal of the upper section from the socket 32- and allowing the entire delivery device to be removed from the car or by the reverse operation installed in the same or any other car provided with sockets 32 and -33.
