SAFETY CAR-CONTROL MEQHANISM.
.Appneationfned January 26, 19,25. serieu No. 4,918.
My .invention relates to improvements in Safety car control mechanism, having` for its'I object to provide passenger cars with Apneumatic door-operating means, the car being provided with a turnstile, making provision tor the passenger, 'in exit from the car, to )perate the door lengine by meansof the turnstile. y y
In connect-ion therewith, my invent-ion provides for door opening from the exterior of the car by a streetfare-t-aker; and for the locking and unlocking of lthe lturnstile lby the motorman, to control the exit of passengers through the turnstile.
From all of whichshould bey understood that my invention relates to passenger ycars of the one-man-operate'd type, in whichy the motormanA has control of the means of exit through a Vsingle ,rear-.end ,door, and that congestion, bya fare-taker stationed in the ,st-reet outside the car, who collects fares from the passengers as they enter the car;
. `The instant inventionis particularly in tended 'for use vupon cars equipped withthe air brake and safety car control mechanism of my` United States Letters 'Patent-,No 1,515,841 issued November 18, 1924.

Fig. 2 is a yvert-ical View, partl in sect-ion, ofthe turnstile mechanism emp oyed in my invention. f f- Fig. 3 is atopplan View ofthe ratchet locking and release mechanism employed 1n connection with said turnst-ile. y
Fig. 4 is a transverse mid-sectional view of the locking cylinder` employedin connection Descrip tion.
The mechanism of 4my inventioniisf'par- `ticularly 'intended for use upon one-m'anf ated byvthe `motorman', when the car `is in vuse asa 'one-man car. I have there illustrated (Fig. 1) a car having a. rearv door 7 'which maybe opened and closed bya street-fare- `Operated cars; or upon two-man-operated i:
taker stationed Outside the ca'rj and operat-l f ing a valve 8. When the door is not Operated by such street-fare-taker, the mechanism of my present invention, tovbe hereinaft'erdescribed in detail, will come into play to permit theingress and egress of passengers through the door 7, V` r l' The tu'rnstilel A consists 'of the lhead1; 12 having the radial arms 13, normally mounted in a horizontal'plane; but the head12 is.
seated inthe tubular standard114as shown in `Fig. 2,'when the arms 13 are in horizontal position, and the headmay be drawn upwardly out of its seat in the upright 14, and dropped intothe approximately vertical position indicated by dotted lines inFig. 2.
This isV effected by reason vof the connection between the h'ead712 and turnstile'shaft 15,
said shaftl 15 having atl its top 4'the vertical loop 16, extending into the cylindrical 'cavity 17 of thehea'd 12, the head 12 being'slidigly e secured to'saidloop 16 by means of the pin 18. yThe shaftvl rotates freely inthe tubular standard 14, .said standard v14 being mounted lin the hollow bearingLblock 2U.
`Withinsaid bearing block 20, the shaft 15 is provided with a box collar 21, 'from which collar 21 the arm 22 extends radially,l-hav ing at its outer end the tubular'ch'an'ib'er 23, 95
:in the lower open mouth of .which tubular chamber 23 a ball? bearing 24 is yieldngly mounted bymeans of the coiled springf25; said ball 24 operati'nguponthe upper surface ofV the circular plate 25,-which plate-25 is provided with the dwell ordepres'sion 26 wherein` said ball 24 ,will rest, as shown' in -Fi`g..2, when the turn-stile A is in its locked position. The said turnstile A is controlled by means rof the ratchetwheel 27 whichA Vin turn is mounted upon the tubular shaft at aV point conveniently below vthe car'- floorl 248-.
'When-the car is in motion the ratchet wheelf27 is' lockedby means 'of the plu-nger 29 being seated inone of the holes 30 Which extend vertically through the ratchet Wheel 27 as shown in Figs. 2 and 3; the plunger 29 is `mounted onthe lever 31, `fulcrumed at 32 and actuated by the operation ot the locking cylinder 33, which contains the piston 34 and rod as shown in Fig. 4, the coiled-spring 36, heldin place by the cylinder head 37 servingdo` normally hold the piston 34 seated as shown in Fig. 4. `The operationof` the motoi'mans valve 6 admits compressed airfto the cylinder 33 through theapipe 3S, actuatingthe `piston 34 and lever 31 td unseat the plunger 29 from engagement With the ratchet-Wheel 27. The same movement of the motormans valve 6 admits air through the pipe 41 to the cylin- ,der`39` to disengagegthe pawl 40 from the :ratchet-Wheel 27 (thecylinder 39 containing a piston 34, rod 35 and coiled spring 36 as inthe case of thecylinder 33 and as shown inl 4 in detail).
` Thebase ofthe turnstile shaft 15 has a socket 42 engaging with the valve-stem 43 ofthe valve 44` which valve i 44 `is described and shown in my United States Letters Patent Nd 1,515,841 issued November 18, .1924, andijorms no part otmy present invention. It `will sutiice to describe said valve 44 as having pipe connections to the main compressed-ail.' reservoir 49: and door-engine 50 (allas described and shown in my former Letters Patent), so arranged that the operation `ot thevalve 44 by the turnstile A, caused by the Vpassage of a passenger through said turnstile A will serve to open the door 7,saiddoor 7 being closedwhen desired by the ymotorman, actuating `.the 'valve 44 throught-he control-.valve 6 and` the pipe connections shown 'iinF-ign5; The controlvalve 6 isrully illustrated in myLetters Patent No. 1,515,841 olf` November 18, 1924, and forms nofpart of my present invention.
The paWl-49is so@ disposed as to permit the reverse movement of the turnstile A caused by` passengers entering the ear throughthe door 7, when that door has been opened? bythe operation of the control-valve i ,8* actuatingcthe door-engine 50.l
Suitable connections between valve 8 and cylinder 33 `release the plunger 29 concurrently with the release of paWl 40.
\ 'Ihepiston 34 with its enclosed elements, constitutes a locking `mechanism Which is formed asshownin Fig.` 4,"the outer annularface 50 having a conoidal shoulder 51 Slitting the beveled valve-seat 52 and terminating in the small circular constricted face .53. The air emitted from the pipe 38 tiret impinges upon` theconstricted tace 53 toiunseat the piston34 from the valve-seat 52, permitting the expansion of the airvolume and its `impact upon the entire piston-head comprising the` constricted face 53,
' of the valve 6.
the shoulder 51 and outer annular face 50. 65
,Wheel 27 the pavvl 40 and plunger29 must bothbe disengaged from the ratchet-Wheel 27. `That disengagement occurs When` the `door 7 has been opened by the operation (by the street-fare-taker) of the valve 8v (see Fig. 1), or (by the motorman) of the `valve 6. Both of these operations are inaccessible to the passengers.
Mode of operation.
`The car upon which my mechanism is installed `being brought to a stop by the motorman, by the operation of the valve 6 the ratchet 27 and locl- 29 are released through the action of the cylinders 33 and 39 disengaging the :plunger 29 and paWl 49. The passengers then eifecttheir exit through the turnstile arms 13, Athe rotation ot'7 the turnstile actuating the stud 43 operating the y control valve 44 to actuate the door engine 50 to open door 7. It the entrance of passengers only is to be effected the street-fare- ,taker by the operation of the valve 8 operates door engine 50 andopens the door 7, and at the same time unseats the plunger 29 from its locking position in the ratchet- Wheel 27, permitting the passengers to pass the turnstile A. The exit of passengers, by revolving the turnstile arms13 and the stud 43 actuates the engine 50 to open the door `7 which may be closed, and the turnstile'A locked, by theV motorman through the use The locking-means for the turnstile A is not accessible to passengers, and is controlled by the motorman through the means above described. f
The shiftingvof the turnstile head 12 into the vertical position indicated by dotted linesin Fig. 2 is intended to economize space when the door 7 is not being used either for entrance or exit purposes.
