'HIL- A opening 17' is not sufficient to permit eqiialintion and the aid piston is therefore .forced downwardly by tlie'expansion of the nir in the inner portion 18' of the c linder f8,V

which will thereby withdraw tie holt f6 from the rod ln to allow tlm piston ll to ho forced luflieiently outward or to the left to enum port 7 in the vulve ll to register with port 8 and allow a prnetieally uniinpeded low from iinxiliiiry cylinder tn' rewrvoir through these ports to the brake cylinder, as shown in Fig. 2. When the brake valve is cloned and promire in the train pipe reaches ita nornnil condition the pinna il in the chamber l2 will be forced to its normal ionition mi shown in Fi l which will itl ow tho rod li'. to ho forvedinielc hy the. ii ring 15' around the Manie, and thus permit tlie rod or bolt 1li to again assume the position as shown in luid Fig. l throftgli its slp-ing li'".

lt will thas he seen that my improved tri le valve foi' air-bralie systems will provice for it lnekine; of the i-ilido valve eniployed therein by ineiiiis of devices connect ed to tlienervieo line and engaging therewith, nml hy sneh means which will be conveniently, readily and quickly operated und will not get ont of order. The loelc can easily and quickly be applied to the ordinary type of qnielt noting triple vnlveii and withont any great exprima vor addition of eoinplieated pai-ni thereto, and heine; self-netting requires im attent ion or eure lieyond the ordinary mich as is given to these valves. The locking device is nnide in the. forni of nn attachment and can be applied to any tri le valve without interfering with any of he part or iidjnntinent of nach valve.

ih'itl'ioini inmlilientionay and changea in llio design, eoinitruetioinnnd operation of' lmy improved triple valve for air-brake syiiteini-i may he resorted to, without departing from the spirit of' the invention or inierifieingiany of' its advantages.
