To all whom it may concern:

Be it known that l, ROGER TV. LOMAX, a citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Apparatus for Delivering Mail from Moving Cars, of which the following is a specification.

This invention relates to apparatus for delivering mail bags or pouches from moving cars, one of its objects being to provide mechanism of this character which can be operated either automatically or manually and which serves to elevate the pouch or bag above the sill of the door opening and to then throw said pouch or bag through the opening and beyond the car structure.

A further object is to provide mechanism of this character which can be adjusted to throw the ba or pouch in any direction desired.

A still further object is to provide means whereby the mechanism may be set so as to be unaffected by coming into contact with the tripping element utilized in connection therewith.

With these and other objects in view the invention consists in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings, Figure 1 is a view partly in section and partly in elevation of the complete mechanism in position upon a car structure, said mechanism being shown shifted to throw a pouch or bag from the car, the normal position of the parts being indicated by dotted lines. view of the parts shown in Fig. 1. Fig. 3 is a side elevation of the tripping arm and adjacent parts. Fig. 1 is a perspective view of one end portion of the rock shaft and the coupling thereon, the angular link being shown adjacent thereto.

Referring to the figures by characters of reference A designates a car structure hav ing a door opening B the sill C of which is extended above the floor of the car structure as ordinarily. The mechanism constituting Fig. 2 is a plan the present invention includes a supporting plate 1 secured to the bottom of the car floor and provided with oppositely disposed ears 2 arranged in pairs, there being a tripping arm 3 pivotally mounted between the ears of either pair. This arm is made up of u per and lower sections 1 and 5 respectively hingedly connected, as indicated at 6, there being cooperating means, such as an eye 7 upon the section d and a hook 8 upon the section 5, for securing the two sections when folded together. A saddle 9 is pivotally connected to the upper end of the section d and permits the tripping arm 3 to swing in one direction independently thereof but, when said arm is swung in the opposite direction, the saddle is necessarily moved therewith. An arm 10 extends from the saddle and has an eye 11 swiveled therein, this eye being pivotally connected to a rod 12. Said rod is slidably mounted within an opening 13 formed in the floor of the car structure and is pivoted at its upper end to an angular link 14 having one end portion hinged within a grooved head 15. This head has side flanges 16 one of which is connected to one side of a hinged cap 17 which is also grooved. This cap' and the head 15 have fastening means such as is indicated at 18 for securing the cap upon the head.

Head 15 is formed on or secured to an arm 19 located at one end of a rock shaft 20, this shaft being provided, at its other end, with an arm 21 to which a link 22 is attached. This link is connected to an operating lever 23 fulcrumed, as at 24 upon the floor of the car structure and having a foot plate 25 at its free end whereby the same can be readily actuated manually.

Shaft 20 is jonrnaled within a bearing plate 26 secured upon the floor of the car and extending from this shaft adjacent the ends of the plate, are arms 27 which are parallel and provided with numerous openings 28. The bag supporting element 29 of the throwing mechanism has one end portion narrowed, as shown at 30 and provided with trunnions 81 adapted to project into any one of the openings 28 in the two arms 27. Additional trunnions 32 project laterally from the supporting member 29 adjacent that end thereof farthest removed from the trunnions 31, and these trunnions 32 are adapted to project into any one of a series of openings 33 formed in each of two parallel arms 34: which are pivotally connected to the floor of the car structure as indicated at 35, these points of connection being arranged at points between the ends of the arms 2?, as clearly shown in 2. Holding pins 36 ma be extended from the upper face of the member 2) adjacent the ends thereof and are provided for the purpose of ei igaging rings or loops formed onthe ends of a mail pouch or bag, as indicated In F g. 2. These pins are preferably hmgedly connected to the member 29 so as to swing downwardly onto said member and thus hold the rings or straps of the pouch upon the member. Cushions 37 of rubber or the like may be arranged upon the car floor at points where they will be contacted by the member 29 when it falls back to its normal position as indicated by dotted lines in Fig. 1.

The arm 3 normally hangs downwardly so as to lie in the path of a tripping roller 38 located close to the track at the point where the mail is to be delivered from the car. This roller is preferably mounted within a frame 39 hingedly connected to a support.- .ing block 10, there being suitable fastening means such as indicated generally at fll for holding the frame in normal position upon the block. By unfast-ening the frame, the same can be swung upon its hinge etO so as to move out of the path of the arm section 5.

A cushioning spring 42 is secured upon the car structure and in the path of one of the arms 27. If preferred two of these springs may be utilized as indicated .in Fig. 2. The springs are so positioned that, as soon as the arms 27 reach vertical. positions during their swinging movement toward the door opening, they will come into contact with the springs and place them under stress, said springs therefore serving to automatically return the arms 2'? to their initial positions immediately subsequent to the delivery of a mail bag or pouch.

The operation of the mechanism 1s as follows: The bag or pouch to be delivered is placed upon the throwing member and i with its rings or straps in engagement with the holding pins 36 which are swung downwardly onto the member 29 as shown in Fig.

2. If the mechanism is to be operated autol rection indicated by the arrow in Fig. 3. Saddle 9 will therefore cause arm 10 to move 1 and rod 12 will be pushed with the arm 3 upwardly. Link 14 will also be pushed upwardly and as it is secured within the head 15 by the cap 17, it will be apparent that rock shaft 20 will be partly rotated and will cause the arms 27 to swing upwardly and outwardly toward the door opening. Member 29 will therefore pull upon the arms 3 1 and both sets of arms 27 and 34- will therefore be swung upwardly and as the arms 341 are longer than the arms 27 it will be apparent that the member 29 will not only be elevated above the sill C of the car door but will also be inclined, as shown in Fig. 1. As the upward movement of the member is very rapid, it will be apparent that the bag or pouch carried thereby will be projected through the door opening, the direc tion of movement of the pouch or bag upon leaving the member 29 being dependent upon the angle of said member to the arms 27 and 34. Obviously this member 29 can be adjusted to different angles by placing its trunnions within different openings 28 and As soon as the bag or pouch has been delivered from the ear the spring or springs 42, which have been placed under stress in the manner hereinbefore described, will operate to throw the arms 27 back past the center of gravity so that the parts of the mechanism will return by gravity to their initial positions.

It will be understood of course that when the bag is thrown from the member 29, the pins 36 will swing outwardly so as to release the rings or straps thereon.

Should it he desired to set the mechanism so that it will not be operated should the arm 3 engage the tripping roller 38. the cap 1? may be releasec. from the head 15 so that. during the upward movement of the rod 12 caused by the swinging of the arm 3. the angular link 14: will be free to lift out of the head 15. Should it he desired to operate the mechanism manually. it would merely be necessary to depress the foot plate 23 whereupon lever 23 will pull on link and arm 21 and cause shaft 20 to rotate.

ll hen it desired to reverse the arts so as to force them to operate when the car is moving in the opposite direction. arm 3 is disengaged from the set of ears 2 support- 1 ing it and is placed in engagement with the 1 other set of ears 2. This does not necessitate detaching arm 10 from rod 12 because the eye 11 is swiveled.
