To al whfmt it 'may concern:

Be it known that I, FRANKLIN H. BURR,-a citizen ofthe United States, residing at Atlantic, in the county oi Cass and the State of' AIowa, hav'ednvented tert-ain neviT and useful Improvements in Mail Receiving and Delivering Mechanism i'or 4Railvvensgaand I do declare thefollowing to be a fuil, clear, and exact description 4of the invention, such vas will lenable others skilled inthe art to 'which it appertainsl to make and use the same.

A is the compressed-air-operating cylinder cut away, showing the piston-rodand return coil-spring .ee encircling the piston-rod, the operating-lever b being pivoted to the pistonrod at point b and connected to the piston by means of piston-rod ee. When the compressed air is admitted to the operating-cylinder through suppl v-pi Je a behind the pis-, tonjf, the piston-ro is t rown out, as shown` by dotted lines, carrying the operating-lever to position, (shown by dotted lines,) the delivery-'frame E in turn being connected by chain to operating-lever b. f' The swinging of frame E from a horizontal position in the car Ac to a perpendicular position, to the" position .shown in Fig. 4. The upsetting or change of position of the delivery-frame E the operating-lever b upsets the deliveringdischarges the mail or other matter placed on the delivery-frame for thatpurpose. The coilspring ee returns the piston ando eratinglever'to their normal positions rea y for the next operation.

t is a cheek-valve and preserves the pressure of the air in the mail auxiliary when the air-pressure isre'duced'in the regular auxillary reser` sure in the operating ofthe air-brake system.

C, Fig. 4, is the regular catcher-crane now 'ingeneral use on all railroads and is hung inv the doorway of a mail-car in the usual inanner and rocks up into position t'o makethe catch andv when ,released from operative position falls by gravity into its normal posivoir by reason of the use of the pres' The return of the piston jf 85 with the operating-lever to their normal posithird, closing as an operating and opening as a Venting-valve, or a triple valve in one, open- .ing and closing in an automatic manner,

six operations.

in operation the valve-lift a, automatically .connected to the operating trigger-arm, lifts valve n by means of valve-stems, which is a rigid part of' valve n, that slides up and down through its supporting-frame to the valveseat n. By this means the valve is closed slackened condition.

as a venting-valve and opened as a checkvalve by raising valve m from its seat m and admits the compressed' air from the eXtra or mail auxiliary compressed-air reservoir into the operating-cylinder through supply-pipe c into port r and through outlet d and pipe 0/ into the operating-'cylinder A, Fig.. l.

The valve m is iitted with a sleeve d, into which the smaller portion of valve-stem sworks up and down in raising valve m from its seat The bottom part of the sleeve d is fitted with a piece of leather for a cushion for the valve-stem S or the portion that .slides in the sleeve d to keep this portion of the abuttal end of the stems from upsetting ordl enlargingby concussion, so that they would stick together, for sticking together would in a measure destroy the com.-

l.plete automatic action of the valve D. The

valve 'n to complete its functions drops lower down in its port n than it raises Valve m in its-port m. For'this reason the valve-stem s must always slide in the sleeve d.

The compressed air being admitted to the operating-cylinder A and said cylinder being fitted with piston, and piston-rod pivoted to operating-lever b, and operating-lel) being connected to the delivery-frame E, behind the pstonj, forces the piston and its connections, the A operating-lever Zi, into the position shown by the dotted lines of the lever in Fig; 1. The operating-lever l) being connected by chain b to the delivery-frame E, then the movement or" the operating-lever into the position shown by the dotted lines of the lever 1n Fig. l causes the delivery-frame E to upset and dump the mail or other packages placed thereon for the purposes of delivery.

- The valve-lift a is conncctedtothe operating-lever b by means of the chain a in a When the operatinglever bis pushed info th. position shown by the dotted lines of lever b in Fig. 1 by the action of the compressed air behind the piston at the last part of the movement of the lever b the slack is drawn out of chain a at the same time and movement, carrying the valve-lift a to the position shown in Fig. l of valve-lift a by the dotted lines.- Whenthe valve-lift a is in this position, the stem s and `valve n are deprived of their support and by means of the air-pressure in pipes and connections forces valve n'and stem s, which is a part ofthe valve, to the bottom of port and into their normal or operative position for the neXt operation. The valve 'm being deprived of the support of valve n drops to its seat mby gravity and the air-pressure ,Y

behind it in the eXtra or mail auxiliary reservoir B and checks the flow of air-pressure into the operating-cylinder A. The valve n drops down when deprived of its support, valve-lift a, in its port n below the ventholes p by reason of gravity and force of airpressure behind it. This action releases the pressure of air in the operating-cylinder and allows it to iiow back through its supply-pipe and out at the vent-holes p. The valve D is then a venting-valve. The release of the pressurebehind the piston in the operating-cylinder A allows' the coil-spring ce to return thepiston and the operating-lever b, by means of its connection to the piston-rod of the piston ]jr, to their normal or operating positions, as shown/in Fig. l.

The valve D is made ofthe material in general usemfor the construction of valves. The detail view shows that thel operating portions of the valve are constructed in diametrical opposition to each other, are automatically connected, and depend on each other for their opposing operating functions. The automatic and self-venting valve D as a whole, Fig. 3, as constructed operates only when set for use in a perpendicular manner. Gravity being a feature of its operation, to use set in a horizontal mafl 1er would require coil-springs to take the place of gravity.

E'is thefdelivery-rame, pivotally hinged to the car Aa, to the sill of the car M, and underneath the door of the car by means of lugs LL. The `pivotal connections at LL are made to the hinge J. The double hinge allows the delivery-frame to be pulled up-into the car and placed inthe position shown of the delivery-frame in the dotted lines in Fig. 6 and in position for the mail or other packages to be placed thereon for delivery, as is shown in Fig. 1l. When the delivery-frame 'is in this position, the bail or back wall g is thrown back, as isshown in Fig. 6. When in this position, it serves as a back wall for the delivery-frame E, to keep the mail or other matter placed on it for delivery from slipping off from the delivery-frame', by its sudden and violent action in operation, it also directs in part4 the angle of thedescent of the mail or IIO 5 when the-d rveryzframe E is raised ma;

the car for operation, it is dumped or upset by the action of the operating-cylinder A and its connections, the lever b and chain b', connected to the delivery-frame E at' lw. In dumping or upsettingthe deliveryffr-ame E it irst turns-on its pivotal point-s JJ until the locking-rod jf intercepts-the hingel J. At this point thefdelivery-frame E, Iin connection with the hinge J ,forms a crank that compels the hinge to turn on it'spivotal oints at 77'; In the upsetting operation of t e delivery-frame' E'it is first upset to anangle of about forty-five de ees. Then. it is thrown out and down by t e'fact of its turning n the hinge J first on its lower pivotal points j and then on all its pivotal points-.and ina descending manner Vat about an angle of fortyive degrees.' y The ybail g, in connection with thedelivery-rame E and the chain-guide holds the frame" at this angle, andthe bail or\ back wall g pushes the mail or other pack- *ages` placed on vthe frame to be delivered at this angle required 'inthe u setting and dumping ofthe delivery-frame The locking-rod j"is cushioned with rubber around' `it, and is placed parallel with the hinge J in the delivery-frame E, Fiv. 4. rllhe open space EE in the'delivery.. aine E lmakes a' step when hangingy in its normal position, as shown in Fig. 4, as a meansorgetting into the car. When'the delivery-frame is `in operative position, as shown in dotted lines,

Fig.A 6, the space EE ,formsa space 'large enough for a mail sack or pouch to vsag ,intoit andy keep itfrom slipping'off from'the frameE..

f is an automatic latch pivoted to the side of the car 'and is adapted to latch the .frame i to the'side ofthe car to keep' the-'deliveryframe E from vibrating or tipping when the iary compressed-airmageservgiifj'to the comitof-a parallel-positiontthecarand rocking" frame is in the'position as shown 'in Fig. 4.' The latch f latches the frame E by Weight of the frame in 4its descent in operation, causing the latch to rise on its heavy end when the frame strikes the angle of the latch next the frame and providing means fort-he frame to ass behindthe latch to a latchingposition. nl raising the. frame E into the car 1t is raised. at a diiierent angle than. its descending angle and is raised out of theila'tch',f.e., the frame' rises out of latch, but descends into latch, therefore making, a complete automatic latclL'.

F is the trigger or automatic operatingarm that Vby reason of its contact with the Yr'oller-bra'c'kt N, Fig..y10, which -is attached to 'the nihil-crane post, Fig. 10,.by,means of a car vinfmotio'ii andthe necessary automatic 'eonnectiohs to the' ,automaticand self-venting va ve D, Fig. 3, opens the valveadmit'- ting the compressed au' fromlthe'mail auxil- .pressed-air-operating cylinder A, thereby set# tingin motion the mechanism that willreceive'a'nd lock a inail-pouch to the catcher C, i

the cars inthe arm of the catcher used to'receive the pouch on the cars.b Whenv the' trigger-arm turns backl from contact 'at 'theV automatic POint N,.Fig.' 10, toward the car, i

the pouch isin' process of being drawn from the mailcrane hangers by` meansfofzthe'. i catcher-crane C in s'uch a manner that the" -Lfshaped portion of the trigger-arm ,comes in' behind the pouch,`roin the fact that the trigger-arm hasfchanged its osition fromv a right angleto rocking bar ,o the catcher C bar of the catcher lC. When the trigger-arm by force of the momentum caused by the contact of the trigger-arm to the rollerbracket N, Fig. .10, is thrown back to the parallel position to the car and catcher, then .the cam, Fig. 8, is released and partially zoy turns around to locking position to the trigger-arm F.. Thel locking-cam J is held in positibn by means ofthe jaw-.angle of the locking-cam. The jaw-angle portion of the A locking-cam is heavier that the other portion,

and the hole in the cam that the rocking bar catcher goes through is out of center for the purpose of making the jaw portion ofthe' cam heavier. In raising the catcher on its rocking bar to its operating position it is then in a horizontal positionl to the car. The locking-cam j by being interlocked in the cam-angles .ze with L part of the triggerarm F is raisedinto a corresponding position. When the trigger-arm F is turned back byl reason of contact-with the rollerlbracket N, it releases the cam y' rom'fits inger-.arm F until the cam y' is released from 'the pressure `against it. Then the cam y' willV again make a turn to a perpendicular position by reason of gravity to the position shown of cam y' in Figs. 2, 4,7. In this position the L portion of the trigger-arm will again interlock with the cam-angles 2.2 and release the triggerarm from its locking position.

. The cam y' is a Hat piece of steel, Fig. 8, and

vpivoted around the rocking bar ofthe catcher C, as shown, and is held in position by means of a collar y and set-screw. l

This completes the automatic connections fron'i the roller` l matic cam The cani (i is a round wheel, of cast-iron', with the cani-notch g supplied with a handle 4(irl for the purpose ot turning the cam G into, position, so that the eccentric 'i will drop into the cam-notch g". this position the cam is ifi operative position. The crank-lever 1li is en 'liet N to the autol .ie outside ot the car,`

and the crank-shaftok goes througli the side of' the car through slotted bar H and is rigidly iXed to the'operating-cam G.

The bar H'is sl'otted at L and v7L andV is movably supported by means of the eccentric vl, which is pivoted to the slottedvbar at 7L and is rotatively supported by the cam G and guided in its up-and-down motion by means of the crank-shaft going through the slot 7L, the bar H being between the cam G and the side wall of the car, and by means of'its being movably supported. at slot hm and bolted'to the side wall of the car, as is shown in Fig. 2. The slotted bar HvmovesV up and down, as is shown by the dotted lines of bar H in Fig. 2, by means of theretating of cam G, raising the bar H by means of its connections to the eccentric-wheel rotating out of cam-notch g".

Pivotally connected to the slotted bar H at point is an automatic rod that has three movements, two by reason of the up-anddown motion ol the automatic bar H and one by reason of its connectionto the valvelift a and the chain connection of the valvelift a tothe operating-lever b, being amovement horizontally "toward the operating-lever b and'corresponding to the movement of the lever b, and by reason of the horizontal movement releases the valve D from operating position and turns the valve D into a venting-valve for the operating-cylinder);A.

The lvalve-lift a is rigidly clamped to the automatic rod between two nuts'."" This allows the valve-lift av to be raisedA and lowered into proper adjustment 'with the stems. l The automatic rod connects the automatic slotted bar H on the insideotI the ear, down through the loor or bottom of the car,

The automatic rod works up` and down.

for the same reasons and purposes claimed for theA slotted bar H, and the dotted lines at the pivotal point and at the vante-lift (t correspond with the dotted lines showing the .up-and-down movement ot the slotted bar H, Fig. 2. The automatic rod zc turns' in a horizontal movement corresponding tothe horizontal f movement of the cam lift (Shown by the dotted lines ot' the valve-'lift a. in Fig. 1.)'

I is the chain-guide for the operating-chain a", connection between the delivery-frame E, and the operating-cylinder A. The chainguide I is a stirrup, of cast-iron or other suitable material, with a bevel-edged concaved edge roller-wheel for chain to roll von, and in connection with the lbail g and the deliveryframe and the hingelock j, and with the air-pressure mechanism directs'a'nd controls the manner and the direction ofthe delivery of the mail or other-matter from the car. x

The receivin -box, Fig, 9, is built of posts, dimension-lumer,`sc ree'n-wire," or any other suitable material,l and,V can be placed, six feet from the nearest rail.v The back side of the boxv-is made about fourand one-half -feet high andthe front side orwside `nearest the track is made about two and one-half feet high and are made of any suitable material. The length is made according-to what is the usual speed of the train, the length needing dposition or to thev position.

to be about, in feet, two-thirds of the miles per hour ofthe speed of the train. The width varies according and one-half'feet. The'receiving-.box Inailcrane, Fi s. 9, 1 0, would be the arran ement lfor a' dou letrack railroad. The ad itional to the amount of the del`spatchof mails, but willvaverageabouttwo' equi ment for a single-track railroad would be t e ,air-cushion box O for the open 'end of Fig. 9 and an additional mail-crane, Fig. 10,l at 'the other end and the mail-crane post equipped with roller-bracket N. To arf range 'this receiving-box to receive.A the despatch of mails between a double or four track road, the back-wall Rv would'be hinged in the middle of itsl hei ht from the ground in a manner to turn own to 'the height of the v.
