To all whom it Indy concern.-

Be it known that I, PETER HUGO SUD- BROCK, a citizen of the United States, residing at New Melle, in the county of St. Charles l this purpose..

Further `objects of the invention are to simplify and improve the construction and operation of this class of devices.

With these and other ends in view, which will readily appear as the nature of the in- -vention is better understood, the sameconsists, essentially, in an improved frame wherein a mail-bag of ordinary construction may be suspended, said frame being adapted to be supported in such a manner as to be conveniently and surely transferred to or from a train while the latter -is in motion.

The invention further consists in an improved means for supporting and catching said frame. A

The invention further consists in the improved construction and novel arrangement and `combination of arts, which will be hereinafter fully described, and particularly pointed out in the claims.

. In 'the accompanying drawings has been illustrated a simple and preferred construction of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein for delivery. Fig. 3 is a top plan view of the trainapparatus. Fig.v 4 is a top plan view of the crane. Fig. 5 is a detail view of a portion of the train apparatus. Fig. 6 is a perspective detail view of the locking or securing mechanism connected with the crane.,

Corresponding parts in the several figures are denoted by like characters of reference.

The invention primarily includes a mailbag-supporting device A, comprising an approXimatelyy rectangular frame 1, the side members of which are provided with sleeves 2 2, whereby said frame is slidably mounted upon the lugs or side members 3 3 of a yoke B. The lower cross-bar 4 of the frame 1 is provided with two vertically-disposed rings or hoops 5 and 6, the lower one of which, 6,' is of much larger diameter than the upper one. The top cross-bar 7 of the yoke B carries two similar vertically-disposed hoops 8 and 9, the

upper one of which, 8, is of much larger diameter than the lower one. Upon the eX- tended lower ends of the side members 3 3v of the yoke B are disposed coiled springs 10, which are confined between the lower ends of the sleeves 2 2 and buttons 11 at the lower extremities of the lugs 3, said springs serving to force the frame 1 automaticallyin an upward direction upon the yoke B. The uppercross-bar 12 and the ring or hoop 5, connected with thelower cross-bar of the frame 1, are provided with hoops 13 and 14, the latter of which includes a coiled `spring 15. Said hoops will serve to support in position a mailbag 16 of ordinary construction, said mailbag being provided with rings or links adapted for engagement with the hoop members 13 and 14.

The mail-bag crane C, which forms a part of the present invention, comprises an upright 16, supporting a vertically-disposed rockshaft 17, which is vertically slidable in suitable bearings 18 upon the post or upright. The rock-shaft is provided with a convenient arm or handle 19, whereby it may be manipulated, said arm being preferably of angular shape. Connected with the upper end of the vertically-slidable rock-shaft 13 is one end of a flexible element, such as a cord or cable 20, which is guided over a pulley 21 at the upper end of the upright 16, and to the other end of which is attached a weight 22,l whereby the rock-shaft 17 and its related parts will be counterbalanced. Suitably connected with the upright 16 is an arm or bracket 23. (Shown in detail in Fig. 6 of the drawings.) Said bracket is provided in its under side with notches 24, adapted to engage the angular operating-arm .19 in the IOO IIO

which carries at its outer end a cross-bar 26,-

it being understood that the arms are disposed approximately in a vertical plane, one

above the other, and that the cross-bars 26 are likewise disposed in an approximately vertical plane approximately at right angles to the plane of the arms 25. Eachof the cross-bars 26 is provided with transverse bars 27, that are suitably spaced from the arms 25. The latter arms are suitably spaced from each other for the ends ofthe cross-bars 26 to engage the large hoops or rings 6 and 8 of one of the bag-supporting frames or devices A when the latter is extended-that is to say, when the frame 1 is moved against the tension of the springs 10 upon the legs or side members 3 3 of the yoke4 B, so as to force the said hoops or rings 6 and 8 apart, so that when said hoops or rings are adjusted upon the cross-bars 26 of the arms 25 the tension of the springs 10 will be exerted to move the said rings or hoops in the direction/of each other, thus causing them to grip and fric? tionally engage the cross-bars 26, upon which the bag-carrying frame or device will thus be held with some degree of security and in such a manner that the greater portion ofthe rings or hoops 6 and 8 will be exposed in the open space intermediate ofthe arms 25.

Journaled in suitable bearings 28 upon the side of the mail-car D is a rock-shaft 29, having cranks 30, provided with laterally-ex tending arms 31, provided near their outer extremities with cross-bars 32. The distance between the arms 31, having the crossbars 32, is so calculated that the axes of the cross-bars 32 shall approximately coincide with the centers of the rings or hoops 6 and 8 of the mail-bag-holding frame or device A, which is supported in position for delivery upon the crane, which has already been described. A frame A of a construction entirely identical with that which has already been described and supporting a mail-bag that is to be delivered from the mail-car will be supported upon the cross-bars 32 of the car apparatus or crane but the small rings or hoops 5 and 9 of said device will be adj usted upon the cross-b ars 32. It follows that the large rings or hoops 6 and 8 ofthe frame or device thus supported will be held in such position that the centers of said rings or hoops will be in approximate alinement with the cross-bars 26 of the crane C.

The rock-shaft 29 will be supported ad? are adapted to engage the cranks 30 of the v rock-shaft 29 when said cranks lie in engagement with the side of the car, as will be best seen in Fig. 3 of the drawings. j

The crane C is to be erected in a convenient position alongside of the railroad-track, and the rock-shaft 29 and related parts is to be connected with the mail-car in such a manner that whenthe rock-shaft is adjusted in operative position the axes of the cross-bars 32 shall be disposed approximately in the same vertical plane as the axes of the c rossbars 26, carried by the arms 25 of the rockshal't 17 upon the crane. It is also obvious that the mail-bag-carrying frame or device that is to be delivered to a passing train is to be adjusted upon the ends of the cross-bars 26 that are distant from the approachingtrain. It is likewise evident that the mail-bag-supporting device that is to be delivered from the train is to be adjusted upon the ends of the cross-bars 32 that are distant from the crane which is being approached by the train.

By manipulating the handle 19 the rockshaft 17 upon the post or upright of the crane maybe lowered and turned to a position in which the arms 25 are approximately parallel to the railroad-track while a mail-bagholding device is' being adjusted in position for delivery to a passing train or is being removed after having been received from 'al passing train. The rock-shaft 29, connected with the mail-car, may also be conveniently manipulated to swing the extremities of theV arms 31 through the door of the car to enable a mail-bag-holding device to be readily adjusted in position or detached, as the case may be.

When the frames or devices A A have been adjusted in position, as will be best seen by reference to Fig. 1 of the drawings, the train moving in the direction indicated by an arrow, the ends of the cross-bars 26 which are near the approaching train will engage the rings or hoops 6 and 8 of the device A, connected with the train apparatus, and will slide the said device A off the cross-bars 32,uponwhich it is supported. In like manner and almost simultaneously the cross-bars 32 will engage the rings or hoops 6 and 8 of the device A, sup'- ported by the crane, and will detach said device irom the crane as the trainV passes by. By the expansion of the springs 10 as the devices A A are being detached from their respective supports the frames 1 will be moved upward upon the yokes B and the hoops 6 and 8 will thus be carried toward each other,

so as to grip the receiving arms or cross-bars,

upon which they will be securely held until they are manually removed.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this' invention will be readily understood by those skilled in the art to which it appertains. The

construction is simple and the operation thoroughly efficient, and it will be noted that the mail-bags will not be directly engaged by the delivering or receiving apparatus, and they will consequently be saved from excessive wear. a,
