To all wlw-m t may concern.'

Be it known that l, Francis J. MGLQUGH- LIN, a citizen ot the United States, residing in Brooklyn, county or' Kings, the State of New York, have invented a certain Improvement in @ne-VVay Exit Gates, ot' which the following is a specification.

At fair grounds, places oi public amusement, railway stations, and similar localities it is desirable to provide means for convenient exit, so constructed as to preventvunauthorized admittance of the publie,fwhile making egress as easy as'possible, particularly in rush hours.

For this purpose it has been customary, in many places, to provide turn-stiles so constructed as to yield to pressure in one direction only, and so constructed as to prevent entrance on the .inwardly moving side of the revolving structure.

One disadvantage of this form of gate is that it must be made necessarily at leasttwice asy wide as the space available for exit, thereby involving a great waste ot space. Another objection-is that the movable structure is heavy to move and makes a great deal of noise when used, particularly when a crowd is passing` through. Again, it a person using the gate is carrying bags or bundles, the horizontal grating set at right angles forms a confining space which Otten occasions inconvenience, and the bars sometimes catch in the clothing or the bundles of the person passing through.

Turnstiles ot this kind are expensive to build and the mechanism is subjected to continual wear and tear, necessitating repairs and consequent interruption'ot trailic.

The present invention. relates to a relatively simple and inexpensive structure, entailing almost no waste of space, and by the use oi which all ot the above named disadvantages ot the usual. turnstile may be obviated.

Certain preferred vforms ot the invention are illustrated in the accompanyingy drawings, wherein Figure 1v is a diagrammatic plan view of a two-door straightaway form ot the improved gate, Figure 2 is a similar view oi" a two-door gate presenting a right angled turn, and Figure 3 is a similar view ot' a two-door gate presenting a reverse turn.

In its simplest form the invention comprises a door l0 made just wide enough to allow one person to pass at a time, and adapted to be opened only from the inside Y outer end of' such 1920. serial no. 375,719.

and by a movement outward only, `as shown by the dotted line at` each door. Such a door is combined nitlrenclosing walls orfences ll, l2, forming a passage on the outside just inea-i5 wide enough tor one person, and suliciently long to prevent anyone reaching in from the onen.

The door isarrangedto close automatically in any well known manner, as by the use of aclosing spring 1.3, or equivalent means. lt the movable edge of the door is made to close flush with the wall or jamb so that it cannotbe pulled open from the outside, this will sutlice, but it is preferable to have a latch lotsome kind on the inside so arranged that it cannot be operated from the outside of thedoor.

It will be clear from thisdescriptionthat any person passing outward through the door 10, as indicated by the arrow, must lea-vevthe passage between the walls l1 and` l2 before time, the door will have been closed automatically, preventing entrance.

passage to hold the door.

an outsider can enter, and, by that The only possibility 'of defeating the `endv Y in `view, with the combination thus tar described. would be `found in collusive action. That is to say one person within might open the door for anotherwho had come inward `toward it, thus admitting the latter.

ln order toy prevent this, it is preferred to embody the inventionin 'the two-door forni shown in three Aarrangements in the drawings. I A i y' ln this form, the walls lll and l2 are prolonged to a second door l5, similar to the door l0, and preferably provided with' a closing device ` Walls 18 and 19 may or may not be used outside oft the second door l5, to torm a narrow passage shown.

l'n Vliggure l the door l5 is parallel to the door 1 0; but if desired the second door may be at right anglesl as at 20, in Figure 2, or at any other angle tothe vdoor 10.

In Figure 3, is showna Vform in which the narrow passage outsideot the iirst door makes a turn throughtwo right angles, the second door 2l opening in rection from the door y10.

l/Vhile it is 16 and an interior latch 17.'

105,y the opposite dipreferred to arrange the-door or doors to onen'outward, as shown, this is lIt will he seen that one of the advantages of the invention is that, if desired, it can be vused as an entrance, by merely a-stening v bach all of the doors.

in times of einen gency this entre capability takes on consiclernble importance.
