APPARATUS FOR DELIVERING AND RECEIVING MAIL.

ilt-3,50%.

To all whom it may concern;

Be it known that I, JOHN H. GnoTzKY, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented a new and useful Apparatus for Delivering and Receiving Mail, of which the following is a specification.

This invention relates to apparatus for delivering and receiving mail and is more particularly designed for effecting the interchange of mail between stations and moving cars.

One of the objects of the invention is to simplify and otherwise improve upon the construction of devices of this character and to so mount them as to render them easy to control and positive in action, the interchange of mail being effected without danger of injuring the bags or pouches handled by the operator.

With the foregoing 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 to m of the invention has been shown.

In said drawings Figure 1 is a perspective view of the complete apparatus and showing the relative positions of the parts immediately prior to the interchange of mail. Fig. 2 is an elevation of the apparatus, the pouches to be delivered being shown in engagement withthe cranes. Fig. 3 is a plan view of the parts shown in Fig. 2. Fig. 4- is an enlarged perspective View of one of the pouch-gripping members of a crane. Fig. 5 is a central longitudinal section through one of the pouch-engaging members. Fig. 6 is a section on line AB of Fig. 5.

Referring to the figures by characters of reference, 1 designates the main arm of the :ar crane, this arm being pivotally mounted upon a rod 2 extending transversely of the Specification of Letters Patent.

door opening 3, which is located, as ordinarily, in the side of the car structure 4. One end of the arm 1 of the crane has an arcuate extension 5 formed with a handle 6 whereby said arm can be readily manipulated and brought into any position desired. The outer end of the arm 1 is provided with a head 7 fixed relative thereto, this head extending in an opposite direction from the arm 1 to form jawsS. Each of these jaws is pointed and has a convex working edge, as shown at 9, there being a recess formed within said edge and close .to the arm 1, as indicated at 10.

An opening extends transversely through the arm 1 close to the head 7 and pivotally mounted within this opening is a shank 11 having jaws 12 at its ends, these jaws corresponding with the jaws 8 and being disposed out of alinement so that, when one of the jaws 12 is swung against the adjoining .jaw S, the other jaw 12 will be.

moved from the opposite jaw 8. Projections 13 extend upwardly from the jaws 12 and either of them is adapted to be engaged by one end of a spring 14 connected to the arm 1. This spring, therefore, serves to hold one of the jaws 12 normally pressed against the adjacent jaw 8, the meeting faces of the two jaws diverging outwardly toward the points of said aws.

A curved arm 15 is secured upon the arm 1 and extended over the slotted portion of said arm, the free end of the arm 13 being spaced from the arm 1 a distance slightly greater than the length of the bag or pouch 16 to be carried. The arm 1 is provided, directly under the free end of the arm 13, with a transversely extending channeled member 17 in which is located a bow-shaped spring 18. The middle portion of this spring bears against a U-shaped bag or pouch-engaging element 19 which is pivotally mounted within the channeled member 17. The U-shaped element 19 is adapted to swing into the channeled member 17 and to engage a ring, strap or the like extending from one end of the pouch or sack 16, there being notches or recesses 20 formed in the sides of the member 17 so as to entening devices on the car crane.

gage said ring, as indicated at 21 in Fig. 6. Another member 22, similar to the member 17, is secured upon the lower face of the outer end portion of arm 15 and is also provided with a bag or pouch engaging member similar to the member 19.

The crane designed to be used at a sta tion, includes a standard 23 having an arm 24 pivotally mounted in the upper end thereof and adapted to be held against swinging movement by means of buttons 25 and a cord or chain 26. This arm 24; has a head 27 at that end thereof nearest the tracks, this head being similar to the head 7 and having pivoted jaws 29 cooperating with it. A spring 30 connects either of the jaws with the arm 24. Another arm 31 is secured to and extends under the arm 24: and is similar to arm 15, both it and the arm 24 carrying a channeled member 32 similar to the

members

17 and 22 heretofore described. Each of these channeled members 82 is provided with an engaging device 33 similar to the device shown at 19 in Fig. 5.

When it is desired to effect the interchange of mail at a station, the bag or pouch to be delivered to the station is placed between the arms 1 and 15 and with its rings or end straps in engagement with the U-shaped members 19, these members being swung about their pivots so as to extend in a direction opposite to that in which the car is traveling and being held in such position by the springs 18. The rings or straps upon the pouch will thus be held within the recesses 20. Arm 1 is swung outwardly from the car and held in any suitable manner. The bag or pouch to be delivered to the car is placed between and connected to the members 32 carried by the arms 24: and 31 and, when thus supported, is directly in the path of the jaws 8 and 12 while the head 27 and the jaws 29 are supported in the path of the pouch or bag carried by the crane on the car. It will be apparent therefore, that as the car passes the station, the pouch supported at the station will be received between the jaws 8 and 12 and pulled off of its fastening members 83 while, at the same time, the pouch or bag carried by the crane on the car, will be brought into position between the head 27 and one of the jaws 29 and will thus be forced away from the fas- As either of the pouches passes into position between the jaws engaging the same, the spring lt or 30 is extended until the said bag arrives within the cut-away portion 10 in the jaw 8 or the corresponding cut-away portion in head 27 whereupon the spring will return the jaw to its initial position and securely hold the bag or pouch in place.

When the station crane is not in use, the

arm 24- can be released from the button 25 and permitted to swing downwardly or upwardly as desired. The crane upon the car can also be swung into the door opening.

In order that the springs 18 may be adjusted so as to increase or dimininsh their pressure upon the members 11), the ends of these springs are preferably connected to adjusting screws 3 1- monnted within the channeled

members

17 and 22.
