MAIL-BAG-DELIVERING DEVICE.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed June 25, 1915. Serial No. 36,333.

The primary object of the invention is the provision of an apparatus of this character wherein a mail bag can be successfully delivered to a passing train from a station, the delivery being automatically effected without requiring the stopping of the train or a reduction in the speed of travel thereof.

Another object of the invention is the provision of an apparatus of this character which is positive in operation and is conveniently set with despatch for the. delivery of the mail bag from a station to a train.

A further object of the invention is the provision of an apparatus of this character wherein on the passing of a train at a station it automatically operates the delivering device, which when set in action throws the mail bag therefrom into the car for its delivery thereto, and thereby obviating the use of a mail bag catcher upon the car.

A still further object of the invention is the provision of a device of this character which is extremely simple in construction, reliable and eflicient in operation, strong, durable, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings :-Figure 1 is a side elevation of a station mail bag delivering device constructed in accordance with the invention showing the same in position relative to the track and set for the delivering of a mail bag to a passing train. Fig. 2 is a top plan view showing by full lines the position of the device in Fig. 1, and by dotted lines the position when the bag is delivered to the train. Fig. 3 is a sectional view on the line 33 of Fig. 1. Fig. 4 is an edge elevation. Fig. 5 is a view similar t Fig. 1,

showing the device released. Fig. 6 is a sectional view on the line 6-6 of Fig. 5.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A deslgnates a portion of a railway track, at one side of which is located the mail bag deliveringdevice for the delivery of a mail bag from a station to a passing train when traveling over the track. This mail bag delivering device comprises a pair of spaced parallel vertically disposed uprights or posts 8 supporting at their upper ends a board or plate 9 constituting the head or crown piece serving as the stand for the delivery device, the uprights or posts 8 being anchored within the groundat one side of the railway track A, or the same may be fastened to a platform at the station. Fixed to the crown or head piece 9 are spaced vertimedially of the said crown or head piece and have journaled therein a rotary shaft 11 to which are connected or fixed the parallel arms 12 of a swinging frame supporting a mail bag receptacle 13 which is fixed to the free end of the said frame and in which is adapted to be placed the mail bag to be delivered to the train.

Surrounding the shaft 11 is a coiled tension spring 14, one end of which is engaged with one of the arms 12 of the frame, while its opposite end has its bearing on or is fixed to the crown or head piece 9 so as to exert a tension upon the frame for the cally arrangedbearings 10 which are located swinging of the same from one side of the shaft to the other.

The frame is formed with a cross bar 15 which unites the arms 12 thereof at an intermediate point of the frame, and this cross bar 15 is adapted to be engaged with the hook end 16 of a trip arm 17 which is pivoted at 18 in the head or crown piece 9 and is adapted to protrude toward the track A so as to be struck by a suitable tripping device upon a moving train for releasing the frame so that it will swing from left to right under the tension of the spring'lt for the throwing of the mail bag from the receptacle 13 thereon into a car of the train.

At the right hand side of the head or crown piece and mounted thereon in the path of the swinging movement-of the arms 12 are impact or buffer springs 19 so that when the arms 12 strike the said springs 19 a sudden jar will be imparted to the frame for the discharge of the mail bag from the receptacle 13 in the direction of the train to be caught by the mail car, as the bag will be thrown through the doorway into the same from the delivery device at the station.

The swinging frame is swung from right to left for the engagement of the cross bar 15 therein with the hook end 16 of the trip lever 17, and in this position the frame is under severe tension of the spring 14: so that when the frame is released it will be swung with great velocity from left to right and the shock of the impact thereof against the springs 19 will discharge the mail bag from the receptacle 13 in the direction of the track so that the bag will be tossed into the mail car when the train passes the station for the automatic delivery of the mail bag from the station to the train.

From the foregoing description, taken in connection with the accompanying drawings, the construction and manner of operation of thedevice will be clearly understood, and therefore a more extended explanation has been omitted.

lVhat is claimed is 1. A mail bag delivering device comprising a stand having a crown piece, a pair of spaced horizontally disposed arms swingingly pivoted to the crown piece, a cross bar connecting the arms, means for supporting a mail bag by the said arms, means for locking engagement with the cross bar and adapted to be automatically tripped by a passing train for the release of the arms, means for exerting a tension upon the arms when released, and means for imparting a shock to the arms for the throwing of the mail bags from the mail bag supporting means in the direction of the train.

2. A mail bag delivering device comprising a stand having a crown piece, a pair of spaced horizontally disposed arms sWingingly pivoted to the crown piece, a cross bar connecting the arms, a rectangular open front receptacle for supporting a mail bag at the outer ends of said arms, means in advance of the pivot of said arms for lociing engagement with the cross bar and adapted to be automatically tripped by a passing train for the release of the arms, means for exerting a tension upon the arms when released and means in rear of the pivot of said arms for imparting a shock to the arms for the throwing of the mail bags from'the receptacle in the direction of the train.

3. A mail bag delivering device comprising a stand having a crown piece, a pair of spaced horizontally disposed arms swingingly pivoted to the crown piece, a cross bar rigidly connecting the arms together, a rectangular open front receptacle for supporting a mail bag at the outer ends of said arms, a hook lever in advance of the pivot of said arms for locking engagement with the cross bar and adapted to be automatically tripped by a passing train for releasing the arms, a coil spring for exerting a tension upon the arms when released, and resilient springs supported by said crown piece in the rear of the pivot of said arms for imparting a shock to the arms for throwing the mail bags through the open space of said receptacle in the direction of the train.

In testimony whereof I aiiix my signature in presence of two witnesses.

ERNEST QUITTENBAUM.
