' 57 to a. convenient fixed part of rocked by the shoe 46 when it is thus shifted upwardly, as above explained, is a pivoted member 52, pivotally mounted at its rear edge as indicated at 90, Fig. 2, and which, when rocked, as above explained, operates to rock a bell crank lever 53, through a link connection 54 to one of the arms of said bell crank lever, the other arm of said bell crank lever` having connected thereto a rod 55, arranged when projected endwise by the rocking movement of the bell crank lever 53 to engage and rock the lever 56 previously referred to, which is pivotallymounted as at the appara'- tus, said lever 56 being arranged, when rocked, to engage thepilot valve operating rod 60 as previously explained and move the saine to shift said p ilot valve. To this end said rod is shown as engaging lever- 56 whereby when the rod 60 is operated the lever 56 is rocked about its pivot 57.
From. this construction and arrangement it will be seen that the manual and automatic operations of the pilot valve are independent of each other.
It is desirable to provide means for locking the motor against operation and to' release the locking sired to shift the door. Thus it -is desirable to maintain the doors locked in their closed position, and the locking mechanism must be so associated that the devices which con.
trol the operation of the pilot valve 38 'also release the locking means in advance of the operation of the pilot valve when said pilot valve is operated manually, 'that -is by the solenoid controllingV means. My 4invention contemplates the provision of means and mechanism for accomplishing this result, and I have shown a construction and arrangement embodying theV principles' of my invention in this respect wherein arod 91 is provided with a lateral arm 59, which is arrangedbetween the' lever 56 and the rod 61 of the solenoid core, crates the pilot valvel 38 being located on the opposite side of said lever 56. As shown the rod 91 extends beyond the lever 56 at its extreme end and is pivotally connected to a gravity actuated locking dog 62 carried by a portion 80 ofthe frame, and pivotally s ecured thereto by a suitable pin 82, as shown best in Fig. 1. Under normal conditions the hooked end 63 of -the lookin do engages a lug 64 upon the cross hea 13, eing engagement therewith and ,hence preventing any shiftheld by gravity in locking p ing movement of the cross head 13 until the locking` dogis released from ment. This release is accomplished lby the red 91 when it is projected endwise by the solenoid, as above explained. The arm 59 such engageis located betweenv the lever 56 and the ,saler noid core rod 61 and the pilot valve operating rod 60 to insure a release of the locking mechanism when it is de-V lmunication with eachy other.
the rod 60 which opvalve chest 25;
. Thereupon t dog 62 wheneverV the solenoid is operated.
After the release of the locking dog, the pilot valve 38 is operated. In the arrangement shown in Figs. 3' and4 the rod 55 extends into position to bear against theffree end of lever 56, whereby when the rodv 55 is shifted automatically by the safety shoe the lever 56 is rocked to operate the pilot valve without affecting the lock. In other words, when the solenoid 43 is energized, the arm 59 is moved toward the right thereby moving the rod 91 and lever 56, thus releasing the locking dog 62 and operating the valve 38. When the rod 55, however, is moved toward the right, the lever 56 and consequently vaive 38 are operated without eii'ecting any operation or movement of the rod 91.
In Fig. 2 I have shown ja motor. mechanism embodying the principles of my invention located between the Wall members 66, 67 of a street car, for instance, and located above the doors in the roof portion of the car, thus illustrating .position the piston 18 would be at the extreme limit of its movement toward the left and the piston 19 at the extreme limit of its the economy of space 1 occupiedK` by the motor mechanism constructed and arranged as above described.
movement also toward the left, that is, port 24 and 28 are in com- This condition exists when the pilot valve 38 is seated in position to close passage 40 and to open passage 39.. Under these conditions the pressure of' the valve chamber 25 is equalized onV opposite sides of valve piston 31, thereby enabling the tension to be exerted to shift and hold the valve 27 in the position shown in Fig. 3. N ow supf pose it be desired toopen the door. To do this switch device 45 is operated to close the circuit of solenoid 43. Thereupon rod- 61 is projected endwise against lever 56 to move the pilot'valve 38 to force the same into its seat to close passage 39 and to open passage 40. `This permits exhaust of pressure from cylinder 32 pressure supply to said cylinder romthe hereupon piston 31 is shifted toward the left by the pressure in valve chest 25 which overcomes the tension 23 is open and ports of spring 33 and shifts valve 27 toward the to the outer air and cuts oil4 of spring 33 left so as to open port 24 to the valve chest orts 23 and 28 to each other.
and to open e cross-head 13 is shifted in the opposite direction and effects through ,n
the links 11 and 12 and their associated levers'the opening movement of the door. i
The opening movement of the door willbe arrested at any point byA merely opening
