To, all whom "it may concern:

Be it known that I, JAMES MILLsAP, a citizen\o,f the United States f America, residingl at De Soto, in the county of Jefferson and State of4 Missouri, have invented new and useful Improvements in Mail-Ba' Deliverers,A of which the following is a speci cation. I

This invention relates to mail bag deliverers, and one of the principal objects of the same is to provide means whereby mail bags may be delivered by means of compressed air, fed to a cylinder and released automatically at points where it is desired to deliver a mail bag and toI provide discharge tubes into which the bags areplaced, one of said tubes being located upon each side of the car, and

bag to ass out. f

Anotv er obiectfof the inventionvis to provide means for automatically .discharging mail bags from a mail car bymeans of compressed-air.

These and other objects` maybe attained by means of the construction illustrated in the accompanying drawing, in which:- Figure. 1 is raiverticall sectional view taken through .a mail car and through the delivery the outer end of-which is open to. permit the' mechanism." Fig. 2is a perspective view of.'

the tri ger" connected to a post at ther point desire to ldischarge a mailbag, said trigger adapted toA engage the end of a lever for releasing a piston to discharge' the ba n Fig. 3 isafsectional view of a check vare conne'cted to the compressed air pipe.

Referring to thedrawing for a more specific description of my invention, the numeral 1 designates a mail car, underneath the iioor. ofwhich'is su ported a compressed air cylinder2, to whic an outlet pipe 3 is connected, said outlet pi e bein provided with a spring-'seated c eck v`a ve 4 comprising al valve casin having" a central partition 5 through whichthe valve stem projects and a valve head (i` adapted to normally close the opening in thepartition 5 by means' of' the stress ofk spring 7 which bears against the partition at one end and against a head or disk 8 at its other end. The pipe 3 is supported in brackets 9 at the side of the car and is provided with a horizontal branch 3El which leads to the center of a cylinder which controls the `compressed air for discharging the mail bags. 'I y i The cylinder 10 'has connected thereto near itsopposite ends a discharge tube 11,

rising from the'tubes 11.

cylinder by a series of bolts 12 and said tubes having enlarged' .outer ends which dpass throu h the opposite sides of the caran ar provi` ed with hinged doors 13 .by means of l ,which the mail bags may be placed Within said tubes with the heads ofv said bags prac tically filling the circumferential space of said tubes. Mounted in the cylinder 10 are a pair of pistons 14, the piston rods of which pass through the cylinder heads and are connected to leversl pivoted at 17, said levers bein designed to o erate the pistons by han to set them in t e required position to discharge the bags.

-A series of jet openin s or perforations 18 is formed in each end o the cylinder 1() and disposed inside the discharge tube 11. Levers 19, each provided with a pivoted stop -pin 20, passing through the discharge tubes 11 and designed to engageone of v'the jet said discharge tubes being connected to the' o enings 18, are pivoted at 21 tol brackets 22 I y The outer ends 23 of the levers 19 vextend out through openings 24 in the sides of the car near the roof thereof. v

At each station, or point at which it is desired to discharge a mail bag, a post 25 is secured, and near the upper end of said post is a trigger `26 having aidownwardly extending arm 27 and a curved terminal end 28 which lies in the path of the outer end 2.3 of the le- The operation of my invention may be brieiiy described as follows: -A mail ba to be delivered is placed in each 'of the tubes 11 throughthe door 13, and said door is then closed. The pistons 14 are adjusted by means of the lever 16 to, the positlon'shown at the left-hand side of Fig. v1, and the pin 2O is inserted in the inner end ofthe apertures 18. ,l

Referring now to the left-hand side of Fig. 1, should a trigger 26 come into contact with the lever 23, said lever would be depressed at its outer end and the pin 20 withdrawn from the cylinder 10. The result would be that the pressure of the compressed air Within the cylinder 10 would move the piston 14 to the position shown-at the right-hand end in Fig. 1. The compressed air. would then escape 'through the openings 18 into the tube 11 upon that side operated and would force the `mai-Iba out, aswill be understood. Then the mai bag for the next station is inserted in the tube 11 through the door 13 and the piston 14 again set in the position shown 'at vthe left-hand side of Fig. 1.

From the foregoing it Will be obvious that bymeans of my construction, mail bags are' automatically dischargedv from the mail car at the'vpoint desired and that a platform or suitable casin may be provided for receiv-l ingvthe bags, i required. 10

y. invention is of simple construction, cannot readily get out of order, Will operate smoothly under varying conditions, can be located at .one end fof a mail car out of the Wayand can be quickly installed for use. Having thus described the invention, what is -claimed as new, is
