To all whom it concerm FRANKLIN H. BURR, or ATLANTIC, IOWA.

, MAIL-RECEIVING MECHANISM FOR RAILWAY-CARS 1, application filed September 14, 1907. Serial No. 392,950.

Be it known that I, FRANKLIN H. BURR, a citizen ofthe United States, and a'resident at Atlantic, in thecounty of Cass andState of Iowa, have invented certain new-and useful Improvements Mail-Receiving Mechanism for Railway-Cars; and I do. declare that the following is a full, clear, and exact descri tion .of the invention, which will enab e' others skilled in the art to which it apper tains to make and-use-the same, reference being made to the accompanying drawings," 'which'formapart of thisspecification;

This invention relates to a mail receiving mechanism for railway cars, and has for its objects, first, the safety of the mail pouch .to be received on. railway-cars while in motion,

by providing means to automaticallylock the mail pouch in the receiving mechanism;

' second to provide means for a greater clearance of the mail crane arms, holding the pouch to be received on the passing train, by

roviding means to-hold the arms in'an Obiquely upright manner until the cab-of the a passing engine has passedthe crane, and then 0 provide means to automatically lower the arms with mail pouch attached into a position tobe taken on b the passing train.

' It is further inten edto providea simple,

durable and efficient construction and one readily adapted to the mail receiving mechanismnowinuse.

- In the drawings, Figure 1 is a side elevation of a mail-crane, showing the application of the safety mechanism on the crane ready for use and includes a sectional end view of a mail-car showing the front end of; a catcher with the safety locking mechanism attached Fig. 2'is front end view of the catcher showing the locking clamp in locking osition', and

V

the 'upper'crane arm.-. Said hook holds the lower'crane-arm in safety position. 1 I

half way between its horizontal and perpendicular ositions would give the desired safety 0 earance position; the 'lower cranearm mustbe raised-to a more nearly perpendicular osition as shown, to give the desired safety 0 earance, and in this position would not gravitate to an operating position quickly enough when released i'i-om its support for a fast moving train to receive t mail-pouch that has been removably' attached to the said crane-arms, without the accelerating downward movement giyen the said cranearms by means of the spring attached to the lower of said crane-armsiand Set" for the purposes named. {Wheiithe crime-arms are raised into thej posiiion (l scribed, they ard" in a safety clearance'posb tion, and are notreleascd from this posltion until the cabohlthe engine hampassed the crane, as the automatic releasing trip is located on the tender 'asdescribed.

In the drawings 20 is a rotary wedgehaped lockingdisk, 23, being the widest, and

' in the narrowest portions of said disk this disk is rotativcly mounted on the rocking bar of the catcher 25, and rocks automaticali y from an operating to a pouch locking position as shown, this disk is rigidly attached to the catcher handle 21, is slotted to receive the looking portion of the locking clamp. thereby making an interlocking position, is elongated between the slots, to adapt itto begln'its locking functions at a slight-or rearii'ard angle of the locking clamp.

Fig. 5 shows a pouch locking clamp, with portions 27, and 28, madeheavier in order to counter balance portion 29, and maintain the clamp in its operating osition, and is pivotally attached to the V s casting32, the 29,,portion of said clamp interlocki ng with the wedge shaped locking disk, when in operating position, and is adapted to automatically rotate rearwardly into a mail-pouch locking position.
