MAIL-BAG CATCHER AND DELIVERER.

To all whom it may concern it known that I,Srm ns'rnR P. gran- LARD, a citizen of the United States, residing.

at Elkhorn, in the county of'McDowell, State of West Virginia, have invented certain'n'ew and useful Improvements in Mail- Bag Catchers and Deliverers; andI do hereby declare the following to be a full,

a :clear, and exact description of the invention,

suchas will enable others skilledin the art to which it appertains to make and use thesame.

This invention relates to new and useful I improvements in mail bagjcatchers and de- 15 liver'ers.

' The principal obj ect of the 1nvent1on is to provide an apparatus that will simultaneously deliver a mail bag from a track structure to a moving car and deliver a mail bag from the car structure to the track structure.

Another object of the invention 1s to pro-.

vide a track structure which is mounted for and deliverer is swingingly mounted so that after the structure has been swunginwardly within the car door, saidcatcher and deliverer may be simultaneously swung in a vertical' plane, thereby .positioning the structure entirely within the door casing.

' I A still further object of the invention is to provide a mail bag catcher and deliverer which is composed of a minimum number of parts, is jtherefore extremely simple in construction and is cheap to manufacture.

' z With these and other ob'jectslin view, the

. invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims here-. to appended; it being understood that va- 'r'ious changes in the form, proportion, size Specification of Letters Patent.

Like reference numerals designate'corresponding parts in all the figures of the drawings.

Referrlng to the drawings, my invention comprlsesa trackstructure which is designated as a wholebythe reference letter A and a car structure which is designated as a whole by the reference letter B. The track A structure A consists of a base 5 which issuitably supported on the ground in spaced relation to the track. The upper end of the base is formed with a socket 6 and the upper edge of said base is formed with a track 7 having a pluralityof depressions formedon its surface. Rotatably mounted within the socket 6 is the lower end of 'apost 8 and this post carries one or more rollers 9 for engagement with the depressions in the track? and serves r are arranged parallel toeachQ other 'and extend inwardly toward the track f (not the socket 6 and v shown). Each arm 11 terminates in an angular free end 12.

A pair of horizontal plates 1313 are each centrally formed with an angular socket 1 1 for receiving the angular end 12 of a respective arm 11. A pin 15 is secured to the extreme end of an angular end 12 of each arm beyond the plate 13, and serves to limit the longitudinal movement of said plate along the arm. The front and rear edges of each plate 13 is formed with a pair of alined angular sockets 1616, each pair of sockets being spaced apart and the plate intermediate each pair of sockets being inwardly recessed to form a pocket 17.

Slidably mounted in each alined pair of sockets 16 are the annular shanks 1818 of a pair of diverging forks 1919. The outer end of each socket 16 is closed by a head 16 and extending through a suitable opening in this head is an adjusting screw 20 which bears against a washer 21. Disposed between the Washer 21 and the adjacent shank 18 is a coil spring 22, said spring serving to yieldably hold the inner ends of the forks 19. against each other. It will thus be observed that the adjacent ends of the shanks 18 cooperate to close the pocket 17.

The car structure B includes a pair of spaced upper and lower bearings 2323 which are secured to one side of the door 24L of a car 25. Rotatably supported in the bearings 23 is a vertical post 26. Extending from this post is a handle 27 by means of which said post may be turned. Extending laterally from the opposite ends of the post 26 are upper and lower arms 2828, said arms being internally threaded for engagement with arms 2929, said arms 2929 each terminating in an angular outer end 30. Mounted upon each angular end 30 is a plate 31 which is identical in construction to the plates 13, and therefore, it is not deemed necessary to specifically describe the same. The upper and lower arms 29 are spaced a sufficient distance apart and are so positioned as to respectively pass above the upper and lower arms 11 of the track structure A. Extending outwardly in the same direction from the arms 29 are rocker arms 32, and a link 33 is pivotally connected at its ends to the outer end of the rocker arm. Connected to the link 33 is a handle 31 by means of which the arms 29 and conse quently the plates 31 may be simultaneously turned.

My invention further comprises a plurality of spools 35, each spool being formed with a wide peripheral groove 36 and a narrow peripheral groove 37. Each spool is formed with a longitudinal bore 38, and this bore is closed at one end by a countersunk washer 39. A coil spring 410 is disposed Within the bore 38, and has one end fixedly connected to the washer 39. A hook 411 is connected to the free end of this spring. The hooks 41 of a pair of spools 35 are connected to rings 42 12 carried by the ends of the mail bag 43.

In practice, a mail bag 43 is attached to the track structure A by means of the spools 35, the smaller peripheral groove 37 of said spools being yieldably held within the pocket 17 of the upper and lower plates 13. It will thus be observed that the larger peripheral grooves 36 are respectively disposed above the plates 13. The spools35 of another mail bag 13 are attached to the car structure so that the smaller grooves 37 are arranged within the pockets 17 of the plates 31. These spools are so arranged that the larger grooves 36 are disposed below the plates 31 and are in register with the nearest fingers 19 of the track structure, whereby the largest grooves 36 of the spools 35 which are carried by the track structure are arranged in alinement with the fingers 19 of the car structure. As the car 25 moves past the car structure A, the front fingers 19 will receive the spools 35 of the mail bag which is carried by the car structure and thereby support said spools within the pockets 17 of the plates 31, thereby catching the mail bag which has been previously carried by the track structure A. Simultaneously with this movement, the fingers 19 of the plates 13 of the track structure will engage the spools 35 of the mail bag which is carried by the car structure B, and these spools will of course be secured in position within the pockets 17 of the plates 13. It will be observed that as the fingers 19 contact with the spools, said fingers will be 'yieldably urged outwardly so as to permit said spools to readily pass into the pocket, and inasmuch as the area of this pocket is smaller than the largest diameter of the spools, the mail bags will be held against accidental displacement.
