'of Georgie have invented e certain new and useful improvement in Antomeiie Stopping or .Signaling 'lleelmnism rer Trains, of which the iollowing is e. fell, clear, end exact description, reierenee being had to the accompanying drawings. This invention relai'es to mechanisnifor automatically controlling moving velneles as they travel peso suitable track devices; the control may be either by .direet amplifietion oi' the lorereoi tlie giving of a snise'nle The oojeez o invention is eo provide vehicle meelianls which shall be very ple in construction, While being eectire service. The reliiele nieenanisin is designed particularly so cenet with that class of track device slioi'en described end claimed. , in myy prior appiieotion, No. 628832, fled Mey ndfll, where there is e steoione ramp invariably operating 'ro open die valve on the renie-ie, and en essoeiaed more able ramp adapted to immediately ele-se air valve "when recl conditions ere safety, buiu otherwise so leave il; open. The invention is licreinefter more fnily explained in eonneetion with e conveniens illustration thereofa and the essentiel eher neterislies are ser ont in ilse. claims. in the' driwings Figure l is e ertiel longitudinal secion ilirongn showing signed for enelinient to anioving reinicie. and containing loe mechanism oi the pres ent invenion. if ,t of suoli meciienisrn r-Z of Fig. l. S is o. seeiionel es indicated oy e of i'. 4 is a side elevaeion of s vehicie rnelr equipped wili eine mechanism, liis showing also one of 'elle track devices coi is e. see-ionel end es indicated by faire line .L f looperating with the vehicle mechanism. ossliown as of n substantial As shown in lie drawings, a suitable box or easing, cured to e moving vehicle, as for exemple to the truck l2 siiown in Fig. This box is rectangular form, open at the incisioni, and an inner vertical Wall 13 and onterbweil intermediate perriion 20 in Figs. ,ind-losses e storione-rg, ramp, positioned 52o co-eeaf-.wili mechanism; l represents adapted@ be selei. and en on the vehicle between the Walls l and 13, and 2l and 22 indica-te bars' designed to maire a ramp, which may eo-ael; 'with meehenisrn between the walls l5 and 14C. it is eo be understood that the bars 2l and 22 are 'pivotally joined together, and the bar 2l is connected with a suitable operating arm 23, which holds the bars in the peaked position shown to constitute a ramp, or may'depress them to a substantial horizontal position so as to be idle. ln Fig. air Valve, is an arm. pivoed on e cross rod 33, and heving e. pin 34 seeing on the plunger 8l. Rigid with the arm 32 is en arm 35, bending l, indicates the casing of an downward to present an operating nose 36, i and then upwardly where it is pivoted to e. sleeve 37, which slides over a. rod 38 piv oed on e. stationary rod 39. The sleeve 37 and rod 38 are provided respectively Wish needs 40 end 4l, s compression spring 42. The spring in normal position (as shown in full lines in Fig. l) tends eo hold the lever 35 depressed, and hold the plunger 3l against its seei; in lie valve casing. The lever 35 described is normally in poe sition to engage the sta'sionary ramp 20, es ne 'veiiiole moves over the same, and suoli engagement raises the lever into the osition shown in dotted lines in Fig. liis op eration swings the erm 32 into the posiion shown in dotted lines, which positively and eeeiyely withdraws if. e plunger 3l from sea., opening the einl salve. The'sprlng e2 and ehe lever 35 inthe nature of e ilogg'le, and as soon as the ramp has ijaised suoli oggle beyond ehe inolgen line riesignnted X, the spring assists the ramp endoperaes to hold elle lever in the open position, when it. clears the ramp. To reset the valve when the moreies ramp is up, between the Walls lll and rigid on the rock Shafer-33, on which the arms 32 and 35 are keyed.m Accordingly, Whenever elle lever 35 is raised, the arm 5G is depressed, from which' it follows the#J as soon as the valve is opened by the raising of the lever 35, die lever is in position to re-set the valve, and will do so if the Inovaiile' ramp is up. The engagement of the lever 50 with this movable ramp swings elle reels shaft and elle arms 32 and 31 the plunger thereof. 32 and between these heads is esv provide a. lever 50 in the sgaoee 15. This lever is 45 and 35, and playeonnection `with the valve whereby it two operating arms and a. third arm conma be Arestored by the movement of the necting with the valve, a. sprin acting on 15 ro er if open, while such movement is idle the lever system, a roller, a sli e carrying if the valve is already closed.
