I UNITED 943,737. Dec; :21, woe
To all whom it may 0022mm; Be it known that l, a citizen of the United Omaha, in the county of of Nebraska, have inventeti useful Improvements in which the following is a spool This inventionrelutes to rail and especially to :1 system in b aims are arranged to be ant plied when the train enters (lan a portion 01 the system becomes {l ar-1 The object of the invention to the engineer from releasing the DYZll an autonmtie application thei T train has elowed down to :2 speed.
I In the aeeompzu ying clrmvin is a tliagrainn'iatie repree brake apparatus embetlyii my invention. Fig. 2 is L tional View of a valve c'mp apparatus.
In the illustrative e1 shown of the invention, 1 "m ti mil, 2 the engineers valve, :1 i
ing from the main .rese hrnhe lliC, 4 a 'iipe i engineers brake valve to th :1 so 5 an znitonnitie 'ul've insert The valve 5, in the shown, comprises P, 0 15' is divided by a partition '3 ii 1 8 and 9, the former being eonneeree engineers brake valve and ti the portion of the train pipe 3 brakes, as shown in Fig. l. i '7 is a port 10 which is the I communication between the i 4 the engineers brake valve. l
in one wall of the (raisin i chamber 9 to the utinos hearing for one end of the recess 13 in the opposite will oi ElllBOili-S provides a hearing said valve stem. L
to the rear of the V21 open to the pressure it; Said recess is herein shown J0 in diameter than the ate 1'1 0f the flow of pressure in intt The valve stem 12 earl-i adapted to elose the per more eheiineis 15 for connect the chamber 9 On one end of said V2 1 I have used the term train to indicate I a locomotive, car or train.
The mechanism illustrated in F ig. 2 is described and claimed in Patent No. 907686 issued to me on December 22, 1908.
I claim as my invention:
1.. The combination, with brake-applying and releasing means, of speed-controlled means for preventing a releasing operation of said means.
2. 1n air-brake apparatus, in combination, a'train line; means for opening the train line to the atmosphere; means for holding said first mentioned means in the inoperative position; and means for locking said first mentioned means in the operative position.
3. In air-brake apparatus, in combination, a train line; means for opening the train line to the atmosphere; means for holding said first mentioned means in the inoperave position; and speed-controlled means or locking said first mentioned means in the operative position.
4. In air-brake apparatus, in combination. a valve arranged to be automatically oper ated to apply the brakes; and means for locking said valveto prevent a brake-release ing operation.
5. 1n air-brake apparatus, in combination,
. a valve arranged to be automatically operated to apply the brakes; and speed-con; trolled means for locking said valve to prevent a brake-releasing operation.
6. In brake apparatus, in combination, a brake device, and speed-c mtrolled electrical 7. In brake apparatus, in combination, a brake device", a locking member connected trolled means with said device; a circuit including an electro-magnet-ic device and a circuit-lncalrcr: a locking member controlled by said electroina netic device and arranged to cooperate Wit the first mentioned locking member;'
and speed-controlled .means for operating said circuit-breaker to open and close said circuit.
S. In brake apparatus,in combination, au-
,tomatic brak -applying means; manuallyoperable means for restoring said brake-applying means after a brake-applying operation; and means for locking said restoring means against operation until the speed the vehicle has fallen to a predetermined point.
brake-applying and releasing means; a. cylinder; a piston in said cylinder; a rod con nected to said piston and said brake-applying and releasing means; a second piston in said cylinder; a manually ope able rod attached to the second piston; and speed-controlled means for lockingthe second mentioned rod against operation.
lOf-Tn brake apparatus, in combination,
' brake applying and releasing means; means for restoring the first mentioned means after a brake-applyin operation; and speed-con- ?or locking said restoring means, against operation, said restoring means being connected to said brake-applying and releasing means so as to permit said brakempplying and releasing means to go to brake applying position without hindrance by said restoring means.
