the holding means being in the form of a'l yleldable latching device lWhich is `adapted to be released by pressure on the door toward closing positionso thatitis unnecessary 'to operate the latch manually in order to'close the door.

Lil.; A furtherobject' of the invention is to pro-y ide a connection/With a yieldable'latching device, a manually operable locking member by which release of the latching means isprevented and the door may be positivelyllockedj lo in an open position.

A further object is toprovide va 'door stop of the character above referred to Which is composed of a minimum number of parts, which is inexpensive to manufacture and;

SQ) Which may be `'easily applied to any hinged' vclosure member. j

A further object is togpr'ovidea door stop in' which movements ofthe door are controlled by a pivoted stop member interposed i1) between the door and door casing and having sliding engagement With guide lmember Which yieldingly engages the stop member and which has a portion formed for latching engagement therewith, the latchingk portion Vof :Io the guide1 bar being yieldable When subjected to the thrust ofthe stop bar ink either direc-` tion so that the door may be Vautomatically latched and yieldably retained in open posi-l tion. j f Y 'n Y A further object isto provide a/manualrly operable loclringniemberufor 'holding the guide bar against movement so as to positively lock the door inopen position and to so mount t locking member thatin its normal posi- 4.3 tion, it does not interiere with the movements of the guide bar.' i L v llfith the above and other objects in" view,

the invention may .be saidtocomprise the deas illustrated in theaccompan'ying draw# oo ings hereinafterdescribed and particularly noonslrorv 192s. srarNo. 286,099. y

Sartini in ai@ appended Claims, together# f ner side'of the door with the door-close dthe locking position of the lock bar being shownV in dotted lines. Fig..3 `is` a section Fig. 'eis a section taken onthe linev indicated at 1 -4 in Fig. 3. 1l l r Referring' to the accompanying drawings, in" which the inventionis shownapplied to an outwardlyV opening door such as a garage door, the door is indicated bynumeral l and is mounted 'in asuitable frame of vvhicha janib Zand lintel 3 are shown", thedoor being connected tothe yjambQ by means of hinges 4L to 'swing outwardly.

Tothe inner side of the door adjacent the. upper edge thereof, there is attached a Wearplate 5 Which is inthe form of a iatgmeta-l strip 'secured tov theface of the door parallel with and adjacent the 'upper edge thereof by means of screws 6. The Wear plate 5 has attached thereto a guide bar 7 formed fromA iiat resilientl metal stock, the body portion of the guide bar being Aparallelwith the vvearf' plate and spaced outwardly therefrom andr the outer 'end ofthe guide bar being bent in`` wardly lat-S andsecured to the Wear plate by. means of a rive-t 9 at a point adjacent the outer end of the vvear'plagte. Adjacent its inner end,

in the inner end 'of the guide bar 7, the aperture being slightly larger than the pin so ythat the inner end of the bar 7 can move reelyon Y ,the pintoward'and from the Wear platef.l

The pin l()l carries a spring ll'vvhich bears 1 upontheouter face `of the 'bar 7 yto press 4the u however, the door may same against the wear plate, the spring being retained on the pin by a nut 12 at the outer end thereof, which may be adjusted to properly tension the spring. A short distance from its inner end, the guide bar 7 is bent to provide a. tapering projection 13 and a recess 1li between the projection and the pin 10.

A U shaped bracket 15 is attached to the under side et the lintel by means oi screws 16 and this bracket has a central aperture 17 which receives one end of a stop bar 18, the stop bar 18 having an end portion 19 bent upwardly and laterally to provide a pivotal connection for the bar in the opening 17 of the bracket. The opposite end of the stop bar 18 has a downwardly bent portion 2O which lies between the guide bar 7 and the wear plate 5, the portion 20 being bent laterally at its lower end to provide a retaining portion 21, the portions 20 and 21 at the end ot the bar providing a hook for retaining the stop bar in engagement with the guide bar.

Vfhen the door is swungto open position as shown in dotted lines in Fig. 1, the end portion 2O of the stop bar 18 moves from a point at the outer end of the guide bar 7, `as shown in full lines in 1, to the inner end of the guide bar, as shown in dotted lines in Fig. 1. W'jhen the portion 2O ot the stop bar engages the tapered projection 13, the guide bai' 7 is pressed outwardly against its own resilience and against the pressure of the spring 11 to permit the portion 2() of the stop bar to pass the projection 13 into the recess 14.. When the end'portion 2O of the stop bar is engaged in the recess 14, the door is latclied in open position. The taper of the projection 13, liowevenewill permitthe stop bar to the projection 13, it stilici nt pressure is applied to the door in a direction to close it.

Under normal conditions, the door will be held open until pressure is applied manually to the free edge oi' the door. Sometimes,

c .u L be s bjected to heav i wind pressures which would torce the stop past the yielding laten and free the door. In order to prevent damage to the door by heavy inds, means is provided by which the door may be positively held in open position. To accomplish this result, a locking device is provided for positively holding the inner end of the guide bar 7 against outward movement so that. the end20 of the i stop bar is positively retained in the recess toe pin guide bar 7, so that it does not inter-tei" with the movements of the bar 7 toward and from the do-or. The bar has a lower end portion 211 bent inwardly at an angle, and normally resting against the face oit door, the aperture in the bar 22, tliro which the pin 10 passes, being oi somewhat greater diameter than t-lie pin so that the bar may be rocked toward and from the door. When the lower end ot' the bar 22 pulled away from the door, the upper end swings to a position immediately over the bai' 7 and it the bar 22 be also m ved laterally, the inner edge of the upper portion 23 of the bar is brought into full locking engagement with the guide bar 7 to pos. lock the inner end oit the bar against 'tl of the wear plat-e so that the door i positively locked in open position. ln oi r to releasably letain the lock bar 22 in locl'- ing position, an angle bracket 25 is secure to the inner tace o't the door at spaced laterally from the normal veiti position of the bar 22 toward the hi gedge of the door. rlhe bracket 25 has in its outer edge, a notch 2d in which 'the bar 22 may be retained. rlhe pressure oi the spring 11 tends to rock the lower edge of the b1 toward the face of the door and wli bar is in engagement with the notch 26, the spring serves to press the bar into the notch so that it will not be accidentally displaced therefrom.

lt will now be apparent that the p t invention provides a very simple and reliable door stop which operates normally as an automatic latch for yieldably retaining the door in open position, but which aise provides means for positively lockiig the door in open position when desired.

It will Valso be evident that the device is composed of a minimum number or parte all of simple construction and inexpensive to manufacture and that the device can be very quickly and easily assembled and attached to a door.
