MAIL-BAG CATCHER AND DELIVERER.

SPECIFICATION formingpart of Letters Patent No. 687,810, dated December 3, 1901. Application filed February 23, 1901- Serial No. 48,509. (N0 model.)

To all whom it may concern.-

Be it known that I, LEALON B. WRIGHT, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Mail-Bag Catchers and Deliverers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings,'forming part of this specification, in which- Figure 1 is a perspective view of my improved mail-bag catcher and deliverer. Fig. 2 is an elevational view of the same. Fig. 3 is a horizontal sectional view of the outer end of the crane. Fig. 4. is a side elevational view of the catcher arranged at the outer extremity of the crane. Fig. 5 is a top plan view of the same. Fig. 6 is a top plan view, partly in section, of the catcher arranged on the side of a car. Fig. 7 is a similar view showing a portion of the side of a car in section with the catcher attached thereto, the arms being in a closed position. Fig. 8 is a detail sectional View of one of the bracket-lugs arranged on a car for receiving the catcher. Fig. 9 is a detail view of the latch for cooperating with the crane. Fig. 10 is a detail View of the spring-catch arranged at the extremity of the delivering-arms. Fig. 11 is a detail sectional view showing the manner of arranging one of the pins in the frame; and Fig. 12 is a detail view of the lower end of the car delivery-bracket and its keeper, together with a lever for raising said deliverybracket.

This invention relates to a new and useful improvement in mail-bag catchers and deliverers, the object being to construct a device of the character described, so as to enable mail-bags to be taken from and delivered to passing trains without requiring stoppage of said trains.

With this object in view the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward point ed out in the claims.

In the drawings, A indicates a post, upon the upper end of which is mounted an arm B, said arm being designed to swing around the post, as shown by the dotted lines in Fig. 1. This arm B is preferably braced by guyrods, said arm being hollow, as shown in Figs. 2 and 3, for the purpose of housing a spring I).

6 indicates a cap-piece arranged on the end of the arm B, which cap-piece is notched or formed with recesses to cooperate with projections on a rotating head 0. This head 0 is arranged upon the outer end of a rod 0', which rod carries a spring-follower c at its inner end for cooperating with the spring I). The construction of the parts above described enables the head 0 to be rotatably adjusted in the end of the arm, the tension of the spring constantly drawing said head inwardly, so as to lock it in its adjusted position. Whenever the head is pulled outwardly, it is free to rotate. This head carries the mail-bag catcher, which consists, essentially, of a frame composed of two members whose outer ends are bent so as to diverge and center the mailbag to be received between them. These members, which are lettered O and C, are connected at their inner ends by cross-pieces, which carry a cylinder D. Cylinder D contains a spring-pressed plunger, to which is attached a rod (1, the spring tending to hold said rod in an outward position at all times. Rod 01 carries a cross-head d on its outer end, which is arrested in its outward movement by pin 0 E and E are curved arms pivotally mounted upon the members C- and C, said arms normally occupying a position wherein their outer ends are separated, as shown in Fig. 6. The arms are arrested in this position by pins 0 A mail-bag being suspended from a moving train is designed to strike against the cross-head d, in which event said crosshead moves rearwardly until it contacts with the rear endsof the levers E and E, such contact forcing said rear ends apart and the front ends together, as shown in Fig. 5, until the rear extremities of the levers E and E engage with springpressed dogs F on the members 0 and 0, when said levers are locked in their closed position. The spring in the cylinder D having a constant tendency to move the cross-head d outwardly too will when the mail-bag is stripped from the car exert itself so as to hold the waist of the bag against the front members and the closed and locked levers E and E. The force with which the bag is delivered into the catcher above described causes the arm B to swing on its post, such swinging motion developing sufficient centrifugal force to cause the head a to move outwardly, the spring I) being compressed, so as to disengage the head and permit the catcher to fall from its horizontal position to the vertical position shown by the dotted lines in Fig. 1. The arm B carries a projection 6 (see Figs. 1 and 2,) which pro' arm extending from the post A, said arm carrying at its outer end a housing and guideways. (See Fig. 9.) This housing carried by arm G is provided with a bore, preferably cylindrical in shape, closed at one end and screw-threaded at its other end, which screw-threaded end is designed to receive a cap-piece g. H indicates a box or housing, the face-plate of which is removed in Fig. 9, said box cooperating with the guideways on the outer extremity of said arm G, whereby lateral movementis permitted. An in wardlydisposed projection h is arranged about centrally the box H, the same being designed as an abutment for two coiled springs h, which are when said head is in its proper position on arm G arranged therebetween and the permanently-closed head and the cap-piece g of said housing. This construction per mits the box H to be moved laterally with reference to the arm G, the springs tending to restore the box to its central position.

I and 1 indicate spring-pressed pawls projecting through the top of the box H and extending toward each other, said pawls being in the path of projection b on the arm B, so that as the arm B swings around in either direction one of the pawls I or I will be depressed, the other of said pawls remaining elevated to arrest the motion of the arm, the depressed pawl 'rising after the arm has passed, so as to lock the projection b of the arm between them. In order to depress the pawls and release the arm, wherebysaid arm may be restored to an operative position, a rod J may be pulled, said rod carrying a head at its upper end engaging with the pawls.

The construction of the catcher above described, which catcher has been referred to as being mounted upon the outer end of arm B, is in all essential respects identical with the construction of the catcher used on the car for receiving the mail-bag suspended from the post. The catcher on the car, however,

is provided with pintles K, (see Fig. 6,) which are received in bearings attached to the side of the car, as shown in Figs. 1 and 7. These bearings are notched at each end, as at 70, for the purpose of receiving lugs and holding the catcher on the car in a horizontal position for well-understood purposes. Both of the bearings referred to are preferably provided with a groove k through which passes a key 10 on the extremity of one of the pintles, whereby in introducing the catcher into its bearing-supports the same is held in a position different from that which it occupies when in an operative position, so that it is impossible for said catcher to be displaced with respect to its bearings except when it is intended to remove same. I prefer to construct the parts so that it is necessary to hold the catcher in a vertical position, the pintles being on the under side in introducing or removing the same to or from its bearing-supports, and when the key 7& is passed through its bearing the catcher .may be swung down to a horizontal position and, if desired to be locked in such position, may be moved horizontally, so that the lugs 7r, will fit in the recesses k. IVhen the catcher is not in use, the lugs may be disengaged from their respective recesses and the catcher permitted to fall, swinging from its bearings, but prevented by the key from becoming displaced. This constrnction enables a ready removal of the catcher to and from the bearings on the car, so that the receiving end of the catcher may be changed according to the direction of movement of the car.

The delivering mechanism on the car consists of a bracket-frame L, movably mounted in suitable bearings, the arms of said frame carrying spring-tongues Z, which are preferably fixed with relation to the arm and swinging members Z, which latter are designed to support the mail-bag. This swinging arm carries a projection Z which is designed to cooperate with the notch Z in the end of the spring'finger, whereby when the arm is in line with the spring it is yieldingly held in ICS position. As the bag is caught by the catcher a lateral pull is exerted, which causes the arm Z to swing on its pivot, it becoming first disengaged from the spring, the bag being then readily stripped from said arm, as will be readily understood.

The delivery-posts are shown in Figs. 1 and 2, being indicated at N. As these posts are similar in construction, I will describe but one of them. 0 indicates an arm pivoted on the upper end of the post N, said arm having a weight 0 at one end, which is sufficient in the absence of the bag being in position on the arm to elevate said arm, as shown at the left in Fig. 1. P indicates an arm pivotally mounted on the post N and having an extension 13, which is designed to cooperate with the post when the arm is in an elevated position, the weight of the arm causing it to drop when its outer end is not sustained by the mail-bag. Each of the arms 0 and P carriesspring-fingers and swinging arms, such as shown in Fig. 10 and hereinbefore described. When the bag is suspended from arm 0, the lower ring of the bag sustaining the arm P, as shown at the right in Fig. 1,

the bag is in readiness to be caught by the apparatus on the car, said bag being of course arranged in the path of movement of the catcher on the car.

I prefer to have two delivery-posts, one on each side of the catchingapparatus herein described, one catching apparatus being arranged on the car as well as one delivery apparatus. Assuming that the car marked X in Fig. 1 is going in the direction of the arrow, the catcher on the swinging arm of the post A would first strip the mail-bag from the delivery apparatus on the car, swinging said catcher-arm until it'is arrested by the pawls, as shown by the dotted lines, said catcher dropping to a vertical position in order to render its carried mail-bag accessible.

After the car has delivered its mail-bag to .the station-catcher the catcher on the car receives the mail-bag from the station deliverypost in this instance the post at the right shown in Fig. 1, the post at the left being out of service when. the car is traveling in this direction. Should the'car be traveling in the opposite direction, the station delivery-post at the left would be in service and the one at the right idle.

As the apparatus above described is exposed to inclement weather, the moving parts are liable to be interfered with by the formation of ice, &c., and I therefore prefer to arrange the stop-pins, pivot-pins for the box, &c., as shown in Fig. 11. The frames 0 and (J are preferably made of parallel members joined together at their forward ends, said parallel members being riveted to the cylin der-lugs at their rear ends, which lugs space the members. If these parallel members were fastened together by rivets or bolts, an accumulation of ice on any of the moving parts operating between them would be detrimental, and therefore I prefer to leave these members free, boring a hole in one, through which passes a screw 0 said screw being threaded into the opposite member. This construction permits the members separating in the event of accumulation of ice on any of the moving parts, said movingparts performing their proper function, the carried ice not preventing their operation.

The delivery bracket or frame L is susceptible of being swung to lie flat against the side of the car across the doorway in order that a mail-bag may be attached thereto by a person within said car, and when said bracket is out of service entirely it may be swung in the opposite direction to the side of the doorway. To accomplish the above, I have formed the vertical member of said frame rectangular in cross section for a greater part of its length, which engages keepers Z and 1, having corresponding rectangular recesses formed therein. Z and l represent cylindrical portions formed on the rectangular member of frame L, which cylindrical portions are so arranged as to be directly beneath the keepers Z and Z when said frame is in its lowermost position or a position at right angles to the side of the car.

Zindicates a lever pivoted to the side of the car and so located as to have one of its ends directly beneath the vertical member of frame L and its other member in convenient reach of the door of said car, whereby the same can be depressed by the foot of a person within said car and cause said vertical member of frame L to rise sufficiently far to bring the cylindrical portions Z and Z wholly within the recesses of the keepers and Z and enable the frame to be swung to one side or the other, as desired. When pressure on lever Z is released, the frame L will descend and cause the rectangular por- 'tions of the vertical member to enter the rectangular recesses of the keepers when said frame is in any of its three positive positions; but said frame will not be permitted to descend' when in a position other than one'of said three positive positions, as will be understood, the same being free to move until one of said positions is reached.

In order to accommodate mail-bags which have become contracted in length by being crowded with mail, I have formed the lower arm L of the frame L yielding by pivoting or hinging the same to the vertical member of said frame and securing thereto a curved leaf-spring, whose upper end is slotted and rests against said vertical member, and through which slot a screw or pin is passed, as is clearly shown in Figs. 1 and 2.

I am aware that minor changes in the arrangement, construction, and combination of the several parts of my device can be made and substituted for those herein shown and described without inthe least departing from the nature and principle of my invention.
