MAIL CATCHER AND CRANE.

SPECIFICATION forming part of Letters Patent No. 646,855, dated April 3, 1900.

Application filed January 18, 1900. Serial No. 1,919. (No model.)

To all whom it may concern:

THEWs, a citizen of the United States, residing at Meridian, in the county of Lauderdale and State of Mississippi, have invented new and useful Improvements in Mail Catchers and Cranes, of which the following is a specification.

My invention relates to mail-bag catchers and cranes, and contemplates the provision of a catcher and a crane for use in conjunction therewith, the said catcher and crane being simple and durable in construction, reliable in operation, and calculated to automatically deliver and receive the mail-bags without endangering the life or limb of postal clerks or persons standing near the crane and without injuring the mail-bags or the contents thereof.

With the foregoing in mind the invention will be fully understood from the following description and claims, when taken in conjunction with the accompanying drawings, in which- Figure 1 is a perspective view illustrating one of my improved cranes and a portion of a car equippedwith my improved catcher, said crane and catcher being shown as holding mail-bags and ready to deliver the same each to the other; Fig. 2 is a side elevation of the crane with parts in section. Fig. 3 is a detail section taken in the plane indicated by the broken line 3 3 of Fig. 2. Fig. 4. is adetail View taken at right angles to Fig. 2 and showing the mail-bag hanger on the arms of the crane. Fig. 5 is a detail section taken in the plane indicated by broken line 5 5 of Fig. 2. Fig. 6 is a plan View, partlyin section, of the catcher. Fig. 7 is a detail view illustrating one of the brackets and a portion of the rock-shaft of the catcher. Fig. 8 is a detail perspective View of the rear end of the catcherbody.

Similar lettersdesignate corresponding parts in all of the several views.

In the preferred embodiment of my invention the mail-bag catcher A is made up of brackets a a, connected to the door-posts b of a car B, a rock-shaft a, mounted in said brackets 00 d and extending in the direction of the length of the car, and a body (1, fixed on shaft 0 between the brackets o at. The

the said main frame.

body dis provided with a mouth e and forwardly=divergin g strips f of resilient material, which are'connected to the forward portions of the walls of the mouth e and have their rear ends arranged adjacent to each other in the said mouth, as shown. Said body d is also provided with a rearwardly-extending arm g, which has its rear end bifurcated, as indicated by h, and provided with a'seat i to receive the T-head of a mail-bag hanger, presently described. The rear bracket ct is provided in its rear side with one or more offsets j, communicating with its central bore, while the shaft 0 is provided with one or more lugs is, designed to seat in said odsets j, and thereby normally hold the shaft 0 against rocking and prevent the body d from swi'nging downwardly. The shaft 0 is normally held against rearward endwise movement by a coiled spring Z, interposed between the body 61 and the bracket a, with the result that the lugs 7c are retained in the offsets j of the bore in the said bracket and the body at is held in the position shown in Fig. 1. WVhen, however, the body (1 and shaft 0 are forced rearwardly by the impact of a mail-bag hanger received in the mouth 6 of the body, said body and shaft will be forced rearwardly and the lugs of the latter will be disengaged from the offsets j. This will permit the body 61 to gravitate to a pendent position in the door-opening of the car, in which position the postal clerk in the car is enabled to remove the bag from the catcher without in any way subjecting himself to danger.

O is my improved crane, which is placed on the ground or on a suitable support in close proximity to the track on which the car B travels. This crane in the preferred embodiment of the invention'comprises a main frame made up of four (more or less) uprights we, having feet 12 at their lower ends and inwardly-directed arms p at their upper ends, and a head q joined to the ends of armsp and having a recess r in its under side and also having inclined planes 5 leading to said re cess, and an upright rock-shaft t, which is journaled at its upper end in the head q of The rock-shaft is provided with two arms U1, both of which have their outer ends bifurcated, as indicated by u, and the uppermost one of which has a projection 1!, designed to be normally held in the seat 7' of head (1 by a coiled spring 2!", interposed between a collar 00 on the rock-shaft and a block 7 in which the lower end of the shaft is stepped. By virtue of this construction it will be seen that the arms a of the rock-shaft will be normally held in a position at right angles to the track on which car B travels; but when the mail-bag hangerin the bifurcations of said arms u is engaged by the catcher A on a moving car the projection 21 will be removed from the recess 0" against the action of the spring 20, and the arms uare swung in the direction of movement of the car, thus enabling the mail-bag hanger to readily leave the bifurcations e of said arms.

On the lower arm u of the rock-shaft t the crane C is provided with a receiver ,2 for mail bag hangers. This receiver .5 has flared mouths b at its opposite ends, so as to enable it to receive from trains traveling in either direction, and is provided with resilient strips 0, which are connected to the inner walls of the mouths and have their inner ends arranged quite close to each other within the months I). The strips 0 serve the twofold function of cushioning the mail-bag hangers when they enter the mouths Z1 and of preventing said hangers from rebounding out of the months I).

D D are the mail-bag hangers which are used in conjunction with the catcher and crane. These hangers in the preferred embodiment of the invention respectively comprise a metallic body (7, in the form of a rod which has a T-head e at its upper end and lateral armsf adjacent to its lower end and also has a collar 9 adjacent to its upper end and a snap-hook h at its lower end, and a sleeve 2 of rubber or other yielding material, surrounding the rod (1 and interposed between an enlargement thereon and the collar g. The yielding sleeve 2" has for its purpose to prevent shock and jar incident to the entry of the hanger in the mouth of the body (1 of the catcher or the mouth of the receiver of the crane.

The operation of my improvements is as follows: A mail-bag is attached to one of the hangers D, and after the body (Z of the catcher A is adjusted to the position shown in Fig. 1 the hanger D is placed in the bifurcation h of said body, with its head a resting in the seat 2' thereof. A mail-baghanger, with a bag attached thereto, is also placed in the bifurcation u in the arms 4) of the crane, and said arms are swung into the position shown in Fig. 1-2'. 0., at right angles to the track on which the car travels. With the parts arranged'as above described, when the ear B reaches a position opposite the crane O the mail-bag hanger on the crane will be guided by the strips f of the catcher-body d into the month thereof. The impact between the catcher and the mail-bag hanger will release the rock-shaft t in the manner before described and swing the arm a forwardly, thus enabling the hanger to freely leave the bifurcations of the arms. The impact between the catcher and hanger will also release the rock-shaft c of the catcher and enable the body (I thereof to swing downwardly, so as to permit of the convenient and safe removal of the received hanger and mail-bag. Coincident with the delivery of a mail-bag from the crane to the catcher as described the mail-bag hanger on the catcher is placed in one of the mouths b of the receiver .2 on the crane and is held therein by the resilient strips 0.

It will be appreciated from the foregoing that my improved mail-bag catcher and crane are simple and embrace no frail parts such as are likely to get out of order after a short period of use, also that the catcher is susceptible of ready attachment to mail-cars at present in use, while the crane is adapted to be readily placed in position at the side of the car-track. I
