To all whomtt may concern: i l
Be it known that I, AnoI-IiiRI-I. HARRISON, a citizen of ,the United States,V residing at Orange,-in the parish of Vernon, State of Louisiana, have invented certain new and useful Improvements in Automatic Air- Couplers; and I do herebusT declare the following to be a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertaiiis to inalte and use the saine. 4
This invention relates to hose couplings toinatic coupling for use in coupling the air hose or steainhose of railroad trains.
One object of the invention is to provide an iniproved general construction of devices of this character.
A second object ot1 the invention is to provide means .whereby the` hose roupliiig may4 inove with the draw-bai' otI the ear so 'that the eoi'iplings will not."becomeiflisconnected Onstartii'ig the train or jain together when the saine is stopped. t
A third Object of the invention is to provide .a novel forni of coupling head for use with such devices.
u A fourth object of the invention is .to pro-V vide a ineans wherebi,1 the coupling heads may be supported to have a slight sliding movement with reference to the draw bai'.
A sixth object of the invention is to pro.
vide an` automatic lock `for the coupling head which will operate to close as the cars The invention further consists in certain Vnovel details of construction and combina` tions `Ot" parts hereinafter fully described,
u' illustrated in.. the accompanying drawings,` and specifically set fo'rth in the claims In the accompanying drawingsplike charactors Ofreferenee indicate like parts in the several views, and Figure `l is a side eleva-V tion of a portion of a` `car constructed in accordance with this invention, a' small portion of an adjoinin` -coupling head being shown. Fig. 2 is a. trent elevation of a car constructed in `acoordance with this inve1i' tion, the'gree'iter` part of the car being broken away and a port-ionof the device being shown in section. Fig. 3 is a top plan View of a pairl of couplers disconnected from the supporting trainee and car, the
lcouplers being shown partlyY 'in section the better to bring out. the details. Fig. l is an enlarged view ot two coupler heads in the position ,assumed pist before coupling. Fig.
5 is an' enlarged detail view ot the hose'at taching nipple used with thisI inwention, the tool for applying the saine being' also shown in this view. Fig. t3 is a face View ot'one endof this nipple. Fig. 7 is a detail view of an airvalveloclt used with this invention. Fig. 8 is ai face View of rt-lie'nipple shown in l he numeral 10 indicates a portion el the .body of a car and thiscar is supported on the usual Wheels 115 vthe details of the truck being omitted as the sainefforin nopart. ot' I Supported between the outer ends of this draw bar is fixed a coupler head typified at lei. At l5 is indicated one of the end sills of the ear. i It will be understood throughoutthat each ofthe .cars to be coupled with this invention isfsiini- [arly provided and the coupling. heads and all parts will be preciselyY alike throughout. Bolted to the undersidev of the diawbal' 12 is an vinverted Usliaped frame '1G the arins' of which are connected at` their' ex treiuities by a rod lli' and between their extremities bya guide 1S mounted upon a rod V19. Slidable on tlietbar 17 is a lsliding ine1n berlO otl U-shape, one of the arms being bent outward to lie beneath the bar 18 as indicated at l1 while the other arin is provided with :iV notch and extends up' along iooV ' normally held'pre'ssed forward by means of lthe sliding' member while the other end larged eye 15 .to receive.
This hanger bolt passes through the shank andthe washer 34. B'y this means the fory mit of slight swinging movement and also Aof some twist and rise and'fall. .50
' :there is 'an opening which forms a continuation of the wall 38 and this opening merges gradually these surfaces being for the purpose of en- .sliding member .and can consequently -yield with respect to carry to receive abolt 30 which passes through the indicatedat 37. This coupling head is prowvided' with a .recess for the reception of a guide pin and this :recess consists of a -ilat than the interior and tapers gradually on 41 is furthermore preferablyl cross section.

This sliding member 20 is furthermore a coil spring 25 whichis carri p ed onthebar '17, one end ofthe coil spring bearing against guide plate may. strike the recess `of aiiother coupling head the vtwo will be caused to position properly for coupling since the finger 44 of each willbe guided into the opening 41 of the opposed coupling., These coupling heads are each further, provided with an opening 45 extending therethrough and in tliisopening 45 i'sield a nipple for the attachment of lair consists of a central body portion 46 having an enlarged threaded end 4.7 and this threadbears against'the rear ai'mof the .ll-'shaped frame 16.
The coupling headl is provided with a shank 26 'which has at its rear end an enportion 27. suitably perforated the bolt 24.- The eoupling'head is thus connectedV to the sliding member 20 the draw bar 12, the yielding being permitted by the compression of the spring 25.

This yoke is 'perforated centrally il as leather, 'rubber or the lik Furthermore, tool receiving recesses receiving therpanner teeth 51 of a socket' spaniier 52. iis nipple' or lbushing 46 is bored out at the opposite end and threaded as indicated at 53 and within tliis threaded portion is fitted tlie'threaded end 54 of a coupling nipple 55 .provided with a collar 56 adapted to butt against the end of the nipple 46 when in proper position. It will bp obvious that the head t iat the nipple will fit therein and that it will be threaded for the reception of the threads 47. Iii, positioning this nipple the coupling nipple 55 is removed therefrom yand the nipp e 46 screwed into the couplerl head bymeans of the socket Spanner 52. -Tlie coupling nipple is then screwed .into

For the purpose getlier from accidental release on each of ,these` heads .there is provided a locking niemberor` hook 57-which is pivoted as at, 58 and is 'provided with a rearwardly eX- tending arm 59 whereto is coniiecteda .link

This plate 62 is connected to the link 60 as indicated at 64v plate is provided with a lu 65 connected by means of a chain 66 to a p ate 67 secured to the frame 16. By means of this construction as twoof the coupling heads are brought together, the latter being so. arranged'as to project in forward position beyond the coupler 14, theslidinfr member 20 will be forced backward and t e late 62 permitted to Vslide forward. In or er to cause this plate to slide-forward each ofthe locking hooks 59 is provided with a notch '68 which receives one end of a spring l69 secured to into the This opening rectangular in recess previously described.

By this nieans the lever may be pulled or pushedto open orclosed position for the `valve. the lever in either closed or open position a locking member is provided and this loclc ing member consists of a clamping portion 8l which fits around the branch 73 iniinedi ately above the valve' and is secured thereto by means of, clamp bolts 82.
