MAIL-BAG CATC HlNG AND DELIVERING MECHANISM.

SPECIFICATION forming part of Letters: Patent No. 544,900, dated August 20, 1895. Application filed March 13, 1895 Serial No. 541,534. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE R. Miooan, a citizen of the United States, residingat East Springfield, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements inMaibBag Catching and Delivering Mechanism for Railway- Cars; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the ac:- companying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention consists in the improvements in mail-bag catching and delivering mechanism for railway-cars, hereinafter set forth and explained, and illustrated in the accompanyin g drawings, in which- Figure 1 is a vertical transverse section of a railroad-car embodying my deviceon the line 2 2 in Fig. 2, looking in the direction of the arrow. Fig. 2 is a horizontal section of the same on the line 1 1 in Fig. 1, looking in the direction of the arrow. Fig. 3 is a like horizontal'se'ction of the same, showing the mail bag catching mechanism closed up against the side of the car. Fig. 4 is a view of a section of the side of the car on the line 3 3 in Fig. 3, showing the door for automatically closing the opening through whichthe mail-bags are received into the car. Fig. 5 is a vertical section of a railroad-car, illustrating the operation of the mail-bag-delivery mechanism of my device. Fig. 6 is a horizontal section further illustrating the same. Fig. 7 is a detail view of asection of the cranerod for suspending a mail-bag, illustrating the bag-hook thereon.

In the accompanying drawings, illustrating my invention, A is an ordinary railway mailcar. In the side of this car, preferably near the end thereof, I cut a rectangular opening B, and on the outside of the car, at one side 19 of this opening, I hinge a vertical plate or frame 0, to the bottom of which is secured a triangular plate D, preferably made in two sections at and d hinged together, so that when the plate or frame 0 is closed up against the side of the car, as illustrated in Fig. 3, the

. ledge d adapted to engage the inside of the car when the plate or frame C is open, which limits the outward movement of said plate to,

say, about an angle of forty-five degrees. on

the inside of the car, on the side I) of the opening B, is hinged a door E, provided with a spring 6 for automatically closing said door, this feature being clearly shown in Fig. 4. To the upper edge of the outer end 0 of the plate or frame 0 is secured a bar F, formed into the segment of a circle, so that as the plate or frame 0 moves in or out the said bar will travel freely between friction-rollers ff on the inside of the car at the top of the opening B. To the inner end of this bar F is piv- 7o oted the end of a link G, and to the center of the link G is pivoted the end of a link H, the opposite end of which is pivoted to a support I at the opposite side of the car, all of which is clearly illustrated in Figs. 1, 2, and '3.

To the floor of the car, near the end thereof, is hinged an upright buffer plate J, behind the upper part of which are bufier-springsjj.

A stop 7" is also secured to the side of the car to limit the outward movement of the plate J, and to the top of the buffer-plate J is secured a cord K, the other end of which is secured to the end h of the link H, so that when the plate O is moved outward and the curved bar'F and the'links G and H are in the posi tionshown in Figs. 1 and 2 the cord K is rigid, as shown in'Fig. 2; but when the upper end of the buffer-plate J is moved back by compressing the springs j j the cord K operates to draw the links G 1-1 out of alignment, as 0 illustrated in Fig. 3, and close the plate or frame 0 up against the side of the car. To draw the links G H into alignment and throw the plate or frame 0 outward, as illustrated in Figs. 1 and 2, I provide a cord L, secured 5 to the end g of the linkG,and runningpreferably over pulleys Z Z on the frame of the car, the end Z of which cord the operator pulls for said purpose.

At the side of the railroad-track I erect a 10:)

crane-frame M, to which is pivoted the ends of a curved crane-rod N, and below this curved rod is a pivoted brace m, having a slightlyforked upper end, adapted to engage one of the sides of the rod N and hold it in an upraised position, preferably at an angle of about forty-five degrees, so-that the bar F at the top of the plate or frame will just pass under it as the car Apasses the crane. Upon the central part of the under side of the curved crane-rod N there is an open hook n, as illustrated in Fig. 7, adapted to receive the handles of a mail-bag, which handles can, however, be easily pushed off of said hook in one direction.

In operation the mail-bagis hung upon the hook n on the crane mechanism M N, as illustrated in Figs. 1 and 2, and as the car is approaching the crane the mail agent in the car pulls the cord L, throwing the plate or frame 0 outward, as illustrated in Figs. 1 and 2, and as the curved bar F strikes the upper part of the mail-bag suspended upon the hook n of the crane the bag is pushed off of the hook, and theforce of the contact carries it behind the plate or frame 0 until it strikes and opens the automatic door E, which yields to the impact of the bag and allows it to pass through the opening 13, when it strikes against the upright buffer-plate J, which, in receiving the impact of the bag, is forced back, compressing the springsjj until the cord K, operating upon the links G and H, automatically closes the plate or frame C up against the side of the car.

In Figs. 1, 5, 6, and '7 I show the mail-bagdelivery mechanism of my device pivoted to the sides of the door-frame O. In the side of the car is a curved rod N of substantiallythe same shape as the crane-rod N of the crane mechanism hereinbefore described,and which is also provided with an open-sided hook n. (Clearly illustrated in Fig. 7.) This curved rod N is provided at one side of the door with a suspending-cord P, which passes un der a pulleyp on the upper part of the doorframe 0 and over pulleys 19 p to the inside of the car, where it is provided with a weight 13 which operates to automatically swingthe crane-rod P up over the top of the door-frame 0 out of the way when not in use. side of the railroad-track, preferably at the base of the frame M, I construct a frame Q of suitable height, upon which I secure a rectangular box R, having an open end in the direction of the approaching car, the top of this box being of such height that the cranerod N on the side of the car A will just pass over it, as illustrated in Fig. 5. This open end Ipreferably provide with spring-actuated doors '2" r r 7", which are so shaped that when closed they form substantially the frustum of a pyramid pointing inward, and are adapted to yield to the impact of a mail-bag striking them, so that they will open back against the sides of the box and allow the bag to pass into the box, when the springs r behind them automatically close them.

. In operation the crane-rod N is let down,

At the as illustrated in Figs. 5 and 6, and a mail-bag suspended on the hook it thereon, the bottom of the bag being preferably hooked or tied loosely to a hook 0 on the door-sill of the car A, and as the car passes the box R the upper edge of the open end of the box shoves the bag off of the hook at on the crane N and the hook 0 on the car, and it is thrown against the yielding doors 0", which open and allow it to pass into the end of the box R.

It is obvious from the description hereinbefore given of my device that it is adapted to simultaneously receive and deliver mailbags, operating automatically therefor and without further attention after having been properly set for the receipt and delivery of mail-bags.

In the description of my invention hereinbefore given I have described convenient mechanism for utilizing it, so as to enable others to construct and use the same; but I am aware that many modifications thereof will readily suggest themselves to others skilled in the art to which my invention appertains. Therefore I do not confine myself to the specific construction of my invention herein described, as
