UTOMATIC nnvnnsna non noon enemas.
Application filed March 22 1922. Serial 1101545316.
To all whom it may concern."
.Be it known that I, LEE P. HYNEs, a'
citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements. in Automatic Reversers for Door Engines, the following being a'full, clear, and exact disclosure of the one form of my invention which I at present deem preferable.
For a detailed description of the present form of my invention, reference may be had to the following specification and to the accompanying drawing, wherein l Fig. 1 shows a door and its operating engine, here indicated as of the pneumatic type with a torsion switch in the dooroperating shaft;
Fig. 2 is a diagram of the electric circuits.
My present lnvention is designed to elimi hate the usual door-shoe now commonly employed on engine-driven doors to reverse the engine in the event of its meeting an obstruction. Such a door-shoe is mounted on the front edge of the door and yields when it strikes the obstruction and thereby acts electrically to stop or to reverse the engine.
In place of-such a door-shoe, I introduce in the driving means between the door and engine a yielding connection which, in the event of the door meeting an obstruction, will operate an electric emergency switch that will cause the reversal of the engine. When the'pressure on the engine is released the yielding connection. will resume its normal position-and again start the engine on its door-closing movement. This yielding connection and switch I term, for convenience, a torsion switch, since I prefer to locate it in a shaft which drivesthe radial doorroperating arm, but the title is not tended to limit its. essential character. To make such a device workable, I have contrived certain associated features which will be described hereinafter.
Referring to the drawing, A represents a door, Which is shown,.for convenience as .a sliding door of any'suitable kind, such, for instance, as is now commonly used on rail- This door is operated by-means of a radial arm 1) on ashaft B' In the in-v outer end of arm D is a roller that travels up and down in a vertical guide (1 on the rear edgeof the'door. The door is moved from one end to the other of, its course by a movement of approximately 180 degrees ro-l tation of the arm D and shaft B2; In line with shaft B is a supplementary shaft B which isdriven in ,a well known manner. by an air engine 1B conventionally illustrated. On the'respective shafts B- and B are the arms 1A and-A which are shown in greater detail in Fig. 2. These arms A and-,A, are normally held together by a spring F, which will not yield under normal circumstances, but are so adjusted and-arranged that in the closing movement of the 7 door, an obstruction of the door will, cause the two arms to separate under the stress of'the rotary shaft B as it endeavors to move the door. On arm 'A is a small switchboard a carrying four contacts 6,7, 8 and 9. On arm A is a switch-blade a which normally bridges contacts 6 and 7, but in the aforesaid emergency will be drawn away from those contacts, breaking the circuit connection between them, and bridge the opposite set of contacts 8 and 9.
In Fig. 2 is a hand-switchK which, for door-closing, will beturned tothe position- C, shown in full lines, and for door opening will be turned to the opposite position O shown in dotted" lines. In the full; line position, C, it will bridlgecontacts 4 and 5 and will bridge contacts 2 and 8 in its dotted-line'position, O. In this figure the door A will, at the end of its closing run, open limit switch 1O and at the end of its opening run will open limit switch 11, these limit-switches being closed at all other times. G and O represent magnets which, in a well known manner, control the engine valves to give it a door-opening or a doorclosing.moven1ent respectively. Illustrationsof magnetic control of this type may be found in Letters Patent 1,247,653".to
the handswitch, to contacts 6 and 7 of the torsion-switch, to door-closing magnet C The door will then proceed to close, but if it encounters an obstruction, the torsionswitch will be shifted, as heretofore explained, to open contacts 6 and 7 and then close contacts 8 and 9. That will de-energize magnet C and establish a new circuit from battery R, to limit-switch 10, contacts 8 and 9 to door-opening magnet 0 Thereupon the door will reverse its direction of travel and continue its opening movement until the pressure on the torsion-switch-is relieved and that switch shifted to break the 1door-openi11g circuit at 8 and 9, closing the circuit of door-closing magnet C at 6 and 7. The door wlllagaln reverse and resume its door-closing progress until it finally,
' By this arrangement a satisfactory control of the door is provided without resort to the door-shoe which has several objectionable features.
WVhat'I claim as new and by Letters Patent is 1.
