Fig. 6 is a detail sectional the bail is prevented from slipping oft the lid by convex springs 23 which are secured to the top of the lid. When the lid is to be opened, the bail may be swung back off the lid top. It will be seen that the spring bail makes a yielding fastening so that when a mail bag is thrown violently into the open side of the cage, it strikes the lid which breaks the force of the shock and yields sufciently to prevent injury to the machine or the bag.

The cage is provided with a dat floor 24, beneath which is a compartment 25 in which the ejecting or discharging mechanism is located. The oorlis provided near opposite ends, with transverse parallel slots 26, best shown in Figs. 4 and 5, which slots receive the guides or hooks 27 and 27 on the under side of the transversely-sliding carriage 2S, shown best in Fig. 3, which carriage is of angular shape, having a bottom portion 29, adapted to slide horizontally on the door 24, and an upwardly-extending back 30 against which a mail bag may rest and which further acts as an abutment to throw out the bag. The carriage has a stop 31 upon its back which is `adapted to strike the back of the cage when the carriage is pushed into the cage.

The guides or hooks 27 are adapted to eX- tend downward through slots 32 in a plate 32 which slides beneath the Hoor 24, and the plate is secured to cross bars 33 which slide on parallel rods 34, these extending transversely beneath and parallel with the ioor 24. lt will thus be seen that the cross bars 33 and the plate 32 form a supplemental carriage to which the carriage 28 may be attached, and by reference to Fig. 5, it will be seen that there is a supplemental carriage in each end of the machine so that the ejecting carriage 28 may be arranged at either end of the machine as desired, this depending upon the direction of the trains in connection with which the machine is used.

The carriage is thrown forward in the manner described presently, when a mail bag is to be ejected, and when thrown forward the front cross bar 33 is stopped by a cushion 35 .l in the front portion of the cage and immedi ately beneath the floor 24. In order that the cage may have as far as possible, a smooth bottom, a plate 36 is used to cover the slots 26 in the opposite end of the cage from that in which the carriage 28 is located, this plate 36 having its back edge held beneath a ledge 36 in the cage and having its front portion bent to form a flange 37 which extends downward on the front portion of the machine, and which is provided with a slot 37, see Fig. 5, adapted to receive a fastening button 38, which is pivoted on the front of the machine and by which the cover plate 36 is held in place.

The front hooks or guides 27 of the carriage extend downward into the path of a transversely-sliding spring bar 39, which bar extends longitudinally through the lower portion of the machine; that is, through the compartment 25, and slides on supports 40 and in slots 4l which are produced in the ends of the machine, the ends of the bar projecting outward through the slots so as to be struck by the lever mechanism used in setting the bar. The spring bar 39 is normally thrown forward by spiral springs 42 which are secured to the bar and to studs 43 in the front portion of the compartment 25. Vhen the bar is thrown forward it is stopped by cushions 44, see Fig. 5, which are arranged in opposite ends and near the front portion of the compartment 25. The spring bar is forced back against the tension of the springs 42 by means of levers 45 which are arranged on opposite ends of the machine, and extend normally in a nearly vertical position, these levers being secured at their lower ends to a shaft 46 which is journaled longitudinallyin the machine,and at their upper ends the levers are connected by a rod 47 which serves as a handle and which makes the two levers operate together so that the levers and handle form practically, a single bent lever. When the levers are thrown forward they are held in spring sockets or holders 48 which are secured to the ends of the cage. On each lever near its lower end is a rearwardly-extending segment 49, which has near its edge, a curved guide plate 50 which is held a little distance from the segment, and between the guide plate and the segment is held to swing a latch or lever 5l which is pivoted near the front end of the segment and opposite the lever 45, and the free end of which is notched, as shown at 43, and provided on its upper portion with an elongated lip 54 adapted, when the leveror latch is turned down, to engage the end of the spring bar 39.

rlhe latch lever 5l is pivoted eccentrically to the center of the segment 49 and consequently when the levers 45 are turned, the segments will first actuate the spring bar and push back its ends, after which the latch levers will engage the spring bar, as shown by dotted lines in Fig. 2, and push the bar back- Ward to the limit of its stroke. On the back side of the spring bar 39 are loops 52 which are of spring metaland normally spring downward slightly, and these, when the bar is pushed back, are adapted to ride over catch pins 53, see Fig. 6,011 an oscillating shaft 54, the pins being round on their front portions so that the loops may pass readily over them but having straight backs which hold the loops in place and consequently hold back the spring bar. The shaft 54 is journaled behind the spring bar in suitable supports, and around it, at one end,is coiled a spring 55, one end 56 of which is secured to the shaft and the other end bears against a stud 57 which projects from one end of the machine. The tension of the spring is such as to normally tilt the shaft forward so as to release the loops 52, and the shaft is prevented from being tilted too far by a pin 58 which pro TOO IIO

jects from the shaft and strikes the pin or stud 57. Vhen the loops 52 ride over the pins 53a mechanism, which will be hereinafter described, is employed for holding the pins in a vertical position so as to restrain the loops and spring bar, which mechanism is adapted to be automatically released, as will Y appear below.

Extending at right angles to the spring bar.

and shaft 54a is a hollow shaft 59, which is journaled in suitable supports 60 and at the rear end of this shaft is a stud 6l, which is adapted to extend upward in a vertical position, as shown bestin Figs-1 and 8, and engage a bent arm 62 on the shaft 54a. When in this position, the shaft 54a is prevented from being tilted and consequently the catch pins 53 are held in a vertical position so as to retain the loops 52* of the spring bar. The hollow shaft and the mechanism contained therein is peculiar to the machine 10, but substantially similar mechanism which will be hereinafter described, is employed in the machine 10. The hollow shaft is held with the stud 61 uppermost by a spring 63 which extends parallel with the shaft and beneath the same, one end of the spring being secured to the shaft and the other to one of the shaft supports 60.

The shaft 59 is longitudinally slottedras shown at 64, so as to receive atkey or lug 65 formed -on the end of atrigger shaft 66, which shaftis adapted to slide longitudinally in the shaft 59 and projects-from the front of the machine, the'shaft 66 having a crank or striker arm 67 at one end which arm projects at right angles to the shaft. On the shaft 66 is a loose collar 68 which is held between fixed collars, as shown in Fig l, anda stud 69 on this collar enters a slot 70 in one end of a horizontally oscillating lever 71 which is fulcrumed near the center, as shown at 72, and swings beneath a support 73, see Figs. 3 and 4, and in a slot 74 in one of the supports 40 of the machine. Around the pivotor fulcrum pin of the lever 71 is a spring 75, one end 76 of which is secured to the support 73 and the other end portion 77 of which is secured to the lever- 71,l and the tension'of the spring is such as to normally throwthe lever and push inward the shaft 66 so that the striker arm 67 will lie against the face of the machine.

The opposite end 78 of the lever 7l is bent upward,as shown lclearly in Figs. 3 and 4, and it terminates in a stud 79 which extends behind and in the path of the spring bar 39. It will be seen therefore, that when the machine is in normal position, the lever 71 will be swung by the spring so as to hold inward the trigger shaft 66, but when the spring bar is pushed back to set the machine, it strikes the stud 79 and tilts -the lever 7l so that the latter, acting on the pin 69, throws the trigger shaft outward and into position for use. When the striker 67 of the trigger shaft 66 is struck so as to oscillate the shaft, the lug 65 on said shaftcauses the hollow shaft 59 to turn and this swings the stud 6l from beneath'the bent arm 62 of the shaft 54",

so that the lspring 55 swings said shaft for- A ward and tilts the pins 53a in a manner to release the loops 522.- The spring'bar'39 is thereby released and the springs 42 draw the spring bar violently forward, and the spring bar carries with it the carriage 28 so that the mail bag, which is deposited on the carriage, is thrown forcibly out of the front side of the cage and into the opposite cage which is adapted to receive it.

When the two machines are brought opposite one another, the trigger shaft of one is adapted to strike the striker arm of the other, and it is obvious that the trigger shafts must be held in different planes, and to this end it is necessary to slightly modify the construc-A tion of one machine, andv such modifications are shown in the machine 10, see Figs. 1 and 7. In the machine 10 a transverse shaft 59? is substituted for the hollow shaft` 59 and is provided with a stud 6,1 operating on the bent arm 62 on the shaft 54a in the manner already described, and the shaft is also held in posii tion by a spring 63 also like the one previously described. The shaft 59, however,is provided at its frontend with a segmental gear 8O which meshes with a similar gear 81, see Figs. 1 and 7,- on a'trigger shaft 82, which in this machine is substituted' for the shaft 66 and which has a key-way 83 therein in which the set screw 84 of the gear 81 isheld, andthis enables the shaft to slide through the gear. The outer end of the trigger shaft 82 is provided with a striker arm 67a which is adapted to extend upward and into the path of the trigger shaft 66 of the machine 10a,see Fig.1. The shaft 82 is provided with a collar 68 and a pin 69 likel that described above, except that in this case the pin 69 extends upward instead of downward, butconnects with the lever 71 in the manner already descrbed. l.

When the machines are to be used, the 1evers 45 are forced back so as to carry back the spring bars 39, and the spring. bars are caught and held in the manner already de scribed, after which the leversarethrown forj ward. The carriages 28are pushed into the back part of the machines, vthe mail bags to be exchanged are placed upon the carriages, the lids-'15 of the machines closed and held by the bails 18, and the machine V10 is wheeled near the track so that the open side of its cage will come very near to .the open'sideof kthe cage on the passing train. As the machine 10a' passes the machine 10, the striker arms 67 and 67 are struck by th- e trigger shafts 66 and 82 so that the shafts 59 and 59a are tilted, and the spring bars released in the manner described, which permits the two spring bars to be thrown' towards each other, and the carriages 28 are also carried forward toward the front portions of the cages and the bag in one cage is thrown into the opposite cage.
