SPECIFICATION forming part of Letters Patent No. 539,373, dated May 14, 1895.

Application filed June 5, 1 8 93.

1 all whom it may concern;

Be it-known that I, BENJAMIN D. AYARS, J r., a citizen of the United States, residingat Chester, in the county of Delaware and State of Pennsylvania,have invented certain newand useful Improvements in Mail-Bag-Delivering Apparatus, (Case A;) and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others to skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to means for delivering mails or packages from moving trainsand it has for its object to furnish an apparatus whereby the mail bags and other packages may be thrown from the moving trains into locked 2o receptacles where they will be secure until taken therefrom by the proper persons, thus obviating a number of difliculties and dangers which will be hereinafter referred to.

With this object inview, my invention con- 2 5 sists in the improved construction, arrangement and combination of parts hereinafter fully described and afterward specifically pointed out in the claims.

In the drawings accompanying this speci- 0 fication, Figure 1 is a transverse sectional view through a car ona plane passing through the door-opening and a front elevation of the receiver, the various parts being in the position they assume just before reaching the re I 3 5 ceiver to deliver the'bag or package. Fig. 2

is a horizontal longitudinal section through one end of a car, showing the delivery-arm in the position in which it is held inside the car when not in use. Fig. 3 is a similar section through one end of a car and a top plan view of a receiver'with the delivery-arm and connecting parts in the same positions as in Fig. 1. Fig. 4 is aside elevation of one end of a car and" the receiver with the parts in 5 the same positions as shown in Figs. 1 and 3 just before the delivery takes place. Fig. 5 is a detail view, being a vertical sectional view of a spring-buffer edge which I may use at the opening of the receiver. Fig. 6 is a Serial No. 476,549. (No model.)

vertical longitudinal section through the receiver, showing in side elevation part of a car just after the delivery of a mail-bag, the delivered bag being shown in full lines in the bottom of the receiver and in dotted lines in the chute through which it is thrown. Fig. 7 is a side elevation of the swing trip-arm upon which the bag or package is hung for delivery, the parts thereof being in the position they normally assume while holding the bag or package. Fig. 8 is a longitudinal sectional view through the same with parts in the same positions. Fig. 9 is a longitudinal sectional view through the same, showing the parts in the positions they assume when the trip-arm strikes the receiver-buffer, whereby the retaining-finger is released. Fig. 10 is a detail view in elevation, showing 'the outer end of the delivery-arm broken away, with the trip attached thereto by means of an intermediate link. Fig. 11 is a view of the triparm and intermediate link in elevation, showing the delivery-arm and the connectingpivotpin in section. Fig. 12 is a detail view showing a'manner of detachably pivoting the delivery-arm to the car. Fig. 13 is a view of the same in top plan. Fig. 14 is a detail view showing the lower bracket of the deliveryarm pivot, and Fig. 15'is a detail view showing the upper or detachable hinge'bracket of the delivery-arm. a

Like parts are designated by thesame letv ters in all the figures of the drawings.

Referring to the drawings-by letters, A is a mail or express car of any ordinary or approved construction having the usual doorway; To the side of such a ca'rfjust inside of one of the doors, are attached brackets 13 B which are shown in several figures of the drawings as simply ordinary pivot brackets but which I show in an approved form in Figs; 90 12, 13, 14. and 15. The lower bracket Bis simply an ordinary pivot bracket with. an opening to receive the lower end of a pintle and the upper bracket B, is composed of a stationary portion 1) to which is hinged apiece b each of these parts containing one half of the opening which is to embrace the upper end of a pintle as hereinafter described. The

piece b is pivoted to the stationary portion 1) of the bracket B by a pin at a and is seecured in position to hold the pintle, by a pin a.

C is an arm substantially similar to the well known mail bag catcher having a pintle (or trunnions) thelower end cof which enters the opening in the bracket B while the upper end 0 is embraced and held between the parts 7) and b of the bracket B. The brackets being attached at one side of the door, they are so shaped, as shown in Figs. 3 and 13, that the pivotal points will be opposite the door space so that the arm 0 may be projected out at a right angle tothe car, and the arm is provided with a suitable handle, inside the car for manipulating it. WVhen not in use,the arm will be held within the car by a suitable catch as at c" in Fig. 2.

The arm 0 at its outer end is made smaller, as at C, Fig. 13, and on this portion 0 is pivoted either the upper end of a link D as in Figs. 1, 10, 11 and 12, or the upper end of a trip arm E, as in Figs. 4. and 6. In either case the construction of the outer end of the arm could be the same and it will be provided, in the full sized portion just inside the reduced part 0, with segmental spaces at to receive inward segmental projections d on the upper end of the link D or trip arm E, the construction being clearly shown in Figs. 10 and 11. These spaces are larger than the projections d and a limited pivotal movementis thus provided for, for purposes hereinafter explained. When the link D or trip arm E is slipped on the pivot part 0' of delivery arm C, it is secured thereon by any suitable means, as for instance by a nut e which may be locked in any suitable manner, as by a pin 6' (Fig. 10).

As before stated, the link D may be interposed between the delivery arm 0 and trip arm E, or the trip arm pivoted directly to the delivery arm. When the trip arm is pivoted direct, there should be a greater movement allowed than when the link is used and in some instances the movement could be unlimited. A single segmental space might also be used in which case there is only one segmental projection.

The trip arm E is provided at its outer end with a hook F and the main body of the trip arm is hollowed out to permit of a finger G, dog H and trigger I.

The finger G corresponds with the hook F in shape and when the mail bag, or package is held ready for delivery, the finger is a continuation of the hook forming a closed ring in which position the finger is held by the dog H which is pivoted in the body of the trip arm and has a tooth h which is held in engagement with a tooth g of the finger, by contact between the upper front corner of the dog and the lower end i of the trigger, as in Fig. 8. The trigger I is pivoted at its upper endin the trip-arm and is normally actuated toward its outside position by a spring J. Its motion is limited by a pin j passing through a slot d. When the trigger is pressed inward to the position shown in Fig. 9, its lower end t'bears against the rear upper portion h of the dog I-I thus raising the front portion of the dog out of contact with the finger G and leaving the finger loosely pivoted so that it will offer no resistance to the passage of the mail bag or catcherotf the hook F. When the finger is thus suddenly released, the trigger will fiy back to its normal position, as shown in Fig. 8 and this will occur more quickly than the bag or package will pass off the hook so that when, by the contact of the bag or package, the finger is extended to the position shown in dotted lines in Fig. 8, it will be held in that position by the dog bearing on the notch g of the finger G thus normally holding the hook open to receive abag or package. The ordinary mailbag K may be hung by its middle on the hook F, as in Figs. 1 and 8, or by its end loops as in Fig. t, itbeing only necessary to hang it so that it will not bind, but will freely move upon and off the hook F when the finger G is released.

L represents my mail receiver which is erected by the side of the track andwhich is provided with a principal compartment M and a chute N. The receiver is supported upon any suitable foundation or frame work and the roof Z covers the main compartment M and nearly all of chute N, ending at the opening of the chute in a buffer 0 which may be made of hard wood, or of leather, rubber or any other suitable material. It may be solid or have a spring backing as shown in Fig. 5. The floor it of the chute is inclined downward and outward and extends a slight distance beyond the buffer 0, so that any rain which may drive in the chute will be drained outward'and thus prevented from running into the receiver and injuring its contents. The receiver is provided with a suitable door P which may be properlylocked. Inside the receiver is a canvas Q which is secured to the roof at q, carried down in a loop and secured to the back or side by strong springs and again up and secured at the other end at q to the side of compartment M, thus form ing a bag-open at the sides-to receive the mail or package thrown into the compartment, thus preventing injury by contact with hard substances.

The operation of my invention may be described as follows: The delivery bar being inside the car-as in Fig. 2-and the trip bar suspended therefrom either directly, or by means of the intermediate link, with the finger G in the position shown in dotted lines in Fig. 8, the mail bag is hung on the hook F. The catch 0 is loosened and by means of the handle, the delivery bar 0 is swung out to a position substantially at right angles to the length of the car-as in Figs. 1, 3, 4, 6, 12 and 13-when the trip bar will be directly in line with the bufier O of the receiver L and the bag directly in line with the chute N of the receiver. The continued motion of the train brings the trigger J of the trip bar E into vio- ICO due to its momentum, causes it to ride off the hook F into the receiver through the chute N, forcing the fingerG into the position shown in dotted lines in Fig. 8, causing the trip arm to swing upon its pivots and ride over the top of the receiver. The return of the trigger I from the position of Fig. 9 to its normal position as in Fig. 8, which is effected by the spring J causes the part 'i to again press the forward end of dog H downward, bringing the tooth it into the notch g of the finger, thus locking the finger in its dotted line, or open.

position of- Fig. 9. The delivery arm is now turned back into the car again and secured by catch a" when the apparatus is again ready for operation. When the mail bag is thrown into the receiver, it strikes against the canvas Q and then drops down into the bottom of the bend of the canvas, thus preventing injury to the bag or contents which might result from contact with a hard substance such as the wall of the receiver. In the receiver the mail bag or package is secured against the weather and is there under lock and key,only author ized persons being able to get at it.

By the use of my apparatus all danger of the bag striking and injurying bystanders is obviated. There is no possibility of the bag striking some adjacent object, such, for instance as a car on a siding,-rebounding under the wheels of a train (as has very often been the case) and resulting in the injury or destruction of the contents. Neither can the mail be thrown into a ditch, sometimes containing water or mud, and the bag and contents be thus damaged. All these and other difficulties are entirely obviated by the use of my.invention, and the cost of the apparatus will be of minor importance when the great advantages attending its use are taken into consideration.

I have particularly described the construction and operation of the apparatus but I desire it .to be understood that I do not confine myself to any such specific construction. Many of the details may be varied without departing from the spirit of the invention. The delivery arm might be attached in a different manner and its sustaining brackets might be secured on the outside of the car, especially where the door was too narrow to permit of its proper swinging out and in.

The trip arm which I have particularly described forms the subject matter of another application for patent of even date herewith and any other construction of trip arm might be used in connection with the main apparatus, without departing from the spirit of my invention.

It will be understood also, that the object of the canvas receptacle is to prevent injury to the bag, and that I claim the right to vary the construction of this inner receptacle so long as I provide for its yielding when the bag strikes it.

Having thus fully described the construction and operation of my invention, what I .claim as new, and desire to secure by Letters Patent of the United States, is- I 1. In a mail delivering apparatus for railway service the combination with the bag holder suspended on the car to swing in a direction opposite to the direction of movement of thecar and a releasing mechanism for the bag, of a receiver located beside the track in the path of travel of the bag and a buffer located in the path of travel of the bag releasing mechanism; substantially as described. 1
