State of New York, have inventedcertain newand useful Improvements in Exit-Door Locks, of which the following is a specification.

This invention relates to door locks and particularly to door locks ofthe panic bolt type and is intended for application on double doors.- The objects of the invention are to provide means wherebyin a double door pressure against either door on the insidewill result in unlatching the "door and permit it to open; these results are obtained without; interfering with the normal openclosing edg of the stationary debit and 12is the closing edge ofi'the moving door. f "The bearing plateil3 is 'securedf to 1 1 and lias the bearing' lugs" 14" formed integral therewith. These lugs support shaft 15' to which the releasing dog 16 is'se'cured, also th'e releasing ing and closing of either door- These and other objects of the invention will be more iullyunderstood from thefollowing specificationandthe accompanying drawings. in which Fig. 1, isa front view of a lock oper- -a ting-Inechanism applied to one of the doors,

Fig. 2, is a side view of Fig. 1; Fig. 3 is a .loekoperating mechanism i applied to .the

other door, Figs. d and 5 are details showing the construction used in Fig. 3. Fig. 6 shows. the operative relation between. the mechanisms on each door Fig. 7 shows the invention applied to a double door and Fig. 8 shows the construction of a latching mechanism that may be used at the top of the door. Similar reference characters are used for similar parts throughout the various illustrations. I

This invention is shown applied to what is .known as a paniebolt lock, that is to a'type having a horizontal bar on the inside which, when pressure is applied thereto unlatches the loc-k and permits the door to open outleasing purposes and a similar.arrangement may he provided on the inside. It is often desirable that the panic bolt type ofrelease be applied to both doors so that pressure on either door will unlatch the stationary door and permit both doors to open outwards. The present invention is designed to accomplish this purpose.
