Specification of Letters Patent.

Patented Oct. 29,1912.

Application filed August 10, 1912. Serial No. 714,462.

and delivering device between moving and stationary objects and the primary object of the invention is to provide a device of this character which will permit a mail bag to be delivered from a moving train to a stationary object at a station and also permit a mail bag to be removed by the moving train from the stationary object.

A further object of the inventionresides in providing a device which will effectively carry out the purpose for which the same is designed without injuring the parts forming the device, nor the mail bags which are caught and delivered and a further object resides in providing a means which will positively lock the bags in their respective members after being caught and delivered.

Still another object of the invention resides in providinga device which is ex 'tremely simple and durable in construction,

inexpensive to manufacture and one which will be very efficient and useful in operation.

\Vith these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is-a plan view of the device applied to use. Fig. 2 is a rear elevation of the same showing a portion of a car in section. Fig. 3 is a perspective View of a portion of the device carried on the stationary object. Fig. 4 is a similar view of that portion carried on the movable object. Fig. 5 is a horizontal section as seen on line 5-5, Fig. 2. Fig. 6 is a vertical section as seen on line 6-;6, Fig. 1; and Fig. 7 is a perspective viewpartly in section of the member carrying themail bag.

In describing my invention, I shall refer to'the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a base or platform adapted to be mounted on a platform or the ground adacent the rails 2 and suitably mounted on the base 1, is a supporting post 3, the upper end of which is inclined rearwardlyfrom the rails, as shown at 4. The post 3 is supported on the base or platform 1 by'nieans of the bracing arms 5 and rotatably mounted on the upper end of the post 3 is a head plate 6 of peculiar design, the sides of which are provided with flaring mouths 7 which terminate in slots or the like 8 and mounted on the upper face of the plate 6, adjacent the outer edge thereof is a goose neck hook member or the like 9, said hook'member being provided with a pair of armslO and 11, the former being stationary, while the latter is hinged thereto by means of the liinge 12. The lower free ends of the arms 10 and 11 form jaw members or the like and extend to points in a plane slightly above the plane of the plate 6 and a coil spring 13 engaged with the arms 10 and 11 normally retains said jaw members on said arms in effective position with respect to one another.

As stated above, the head plate 6 is rotatably mounted onfthe upper end of the post 3 and in order toretain'the same in oprotation, said post is provided. at diametrically' opposite points thereon with the notches 14, the rear walls of which are beveled toward the centers thereof. A depending portion 15 formed on the rear edge of the plate 6 has a locking bolt 16 slidably dis posed therethrough and encircling said locking bolt between the outer end 17 thereof which forms a head or the like and the wall of the depending portion 15, is a coil spring 18. The normal tendency of the spring 18 is to force said locking bolt toward the post 3, whereby the head 17" of the-bolt may enter the notches 14. to lock the plate in op erative' or inoperative position and a finger piece or head member 19 formed on the opposite end of said bolt permits of the same being drawn to its ineffective position atany desired time. When the locking bolt is engage'd with one of the notches let, the plate is held in its operative position so that the goose neckhook 9 is disposed immediately adjacent the rails 2 and when said bolt is engaged with the opposite notch the plate is disposed fin its inoperative position, as

shown-iii dotted lines in Fig. l.

The jaws formed at the lower ends of the I be delivered from a stationary object to a movable object and the mouths 7 terminating in the slots 8 form a means for receiving the mail bag delivered from the movable object to the stationary object and in order to facilitate the delivering and catching of 10 the mail bags, of the usualtype, a stem or rod 20 is provided, the upper end of which is enlarged to form a substantial spherical head 21 and slidably mounted on the lower end thereof is a sleeve 22. Encircling .the

lower end of the stem or red between the extreme free end of the stem and the upper end of the sleeve and inclosed within the latteris a coil spring 23, which normally draws said sleeve 22 in position on the stem,

20 but which permits of said sleeve yielding thereon, and carried on the lower end of the sleeve 22 isa snap hook 2 f-with which may be engaged a mail bag 25 of the usual or any preferred type. The head 21 on the 25 upperend of the stem or rod 20 is adapted to be received in the jaws at the lower ends of the arms 10 and 11 to hold'the same and the mail bag extending therefrom to be readily grasped. by the movable object in a mannerto be hereinafter and more particularly described, and the stem or rod is also adapted to be readily received in the mouths 7 "of the slots 8 and the head 21 thereof will. re tain said stem in position on the plate. -Also encircling the stem 20 above the sleeve 22 is a coil spring 26 which is held between a stationary collar '27 and a movable collar 28 the purpose'of which will be hereinafter and more particularly described.

As stated, the stems 0r rods 20, from which the mail bags 25 are suspended are adapted to be readily received in the months at the opposite sides of the plate 6 and in order to lock the same, after having been once deliv- 5 cred therein, pawls29 are pivotally mounted on the plate to one side of the mduths therein and adapted to extend thereacross. The free ends'of these pawls 29 are adapted to abut studs or stops 30 mounted on the plate on the opposite sides of the'mouths therein, thereby limiting the movement of said pawls in one direction and also mounted on the plate toward the transverse center thereof are the housings 31 in which are mounted the spring forced studs or the like 32. Thegfree ends of these studs 32 project beyond the housings 31 and are disposed in the path of the pawls 29, when disposed in their rearward positions. When vt/he pawls 29 are forced against the projectingportions of the studs 32, the latter will force the sa'me under tension to'their initial positions against the stops 30, and ifgghe stems 20 are disposed in the slots 8, the same Wlll be locked therein.

The above is adescription of. that portion of the apparatus which may be termed the stationary portion thereof or thatv portion which is mounted at the station, but I have also provided an improved delivering and catching apparatusto be carried on the movable object or train. Journaled in a bearing 33 which is mounted on the side of a. car

34, immediately adj accnt the doorway therein is the inner end of anarm 35,- said arm extending in a horizontal. planeand formed on the outer end of said arin is an additional arm 36, extending at\right angles thereto. and in the same horizontal plane therewith. The one end of said arm 36 is formed into a catch fork or the like 37, the outer end of which is provided with a .flaring moutlr which terminates in a slot or the like similar to the slots 8 in the plate 6 and the o pposite'endof the arm 36 has an ad ditional f0rk-like member 38 formed thereon. This latter member 38, extends in a vertical plane at right angles to the plane of the fork 37 and arm 3G and the upper and lower arms thereof are provided with. flaring months 39 which terminate in slots 40- similar to the mouths and slots described and shown in connection with the plate 6.

The slots 40 in the'uppe'r and lower ends of the member 38 are adapted to receive therethrongh the stem 20, the head of the latter resting on theupper face of the upper arm thereof and the upper movable collar 28 on the stem .20 is adapted to contact with the under face of the lower arm of said member 38. When so positioned. the spring 26is contracted and placed under tension so as to substantially lock said stem in said member to prevent casual disengagement therefrom. Tn order to retain the arm 35 with its adiunctive parts in operative position. a bracingarm 41- is provided which is pivotally carried on the side of the car 34 and adapted to engage an opening in said arm 35.

In operation, assuming that the plate 6 has been drawn to its operative position .with a mail bag suspended from the delivery fork 9*thereon, and also assuming that the arm 35 has been drawn to its operative position, and. a mail bag suspended from the delivery member 38 thereof, as the moving train passes the apparatus at the station, the fork 37 will engage the stem 20 suspended from the fork 9 and the arm 11 will, of course, yield and allow said stem to be released therefrom.

As the fork 37 is provided with a look ing apparatus, such as has been described in connect-ion with the months of the plate 6, it will be seen that the stem with the mail bag thereon will be securely held to said fork. At the same time the fork 37 engages the stem suspended from the hook 9, the stem 20 which is carried in the fork member 38 is received in one of the months -7 of the plate 5. As the same enters therein, with considerable force, the locking bolt 16 will be disengaged from the notch 14 and the plate 6 swung on the post 3,saidstem' 20 be-. mg simultaneously disengaged from the member 38. The plate 6 will turn on the post until the locking bolt engages the opposite notch 14 and thereby lock said plate in its in-operative position and dispose the delivery mail bag in position to be released by the station keeper, It will thus be seen that a mail-bag may be effectively delivered and received in both a moving and stationary object and in both instances, the bag will be locked in its respective positions.

From the foregoing it will be seen that I have provided a device which is extremely simple and durable in construction, inexpensive to manufacture and one which will be very efiicient and useful in operation and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various chan es in form, proportion and in the minor etails of construction may be resorted to Without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention, what I claim is 1. In a mail catching and delivering apparatus, the combination with a stationary post, a plate revolubly mounted on the upper end thereof, said plate being provided with flaring mouths terminating in slots in opposite ends of said plate, means to lock said plate in predetermined positions on the post, a hook carried by said plate and pro jecting therefrom, said hook being provided with a movable and a stationary arm adapted to form a pair of jaws to retain a member therebetween, and means to yield ingly retain said jaws in their closed posi tions; of means carried on a movable object to remove the member carried by the arms on said hook and simultaneously deliver a member into one of the mouths formed on said plate.
