The hook 1, `as shown in Fi elusive, consists of athin metal ie plate, and the pivot 6, which ierces the ears or anges 4, is located et vany intermediate point at the.

top and bottom of'the innerA end of the hook. The earsor flanges 4 are bent inwardly adjacent to the attachment plate to arrange their supporting portions the prov er dis# tance apart to corres ond to theft ickness of the hook l, which ts snugly between the outer portions of the ears or flan 'es 4. The inner en d of the hook is provide at the top andbottom with upper and lower horizontal `lugs 7 and 8, the lower lug 8 being normally maintained in.` engagement with Vthe lower `portion-of' the attachment 'plate by a coiled spring 9, having .its outer portion disposed on the upper lug andl secured at its inner end 10 to the` attachment plate, which is preferably provided withfa perforation for he reception of the adjacent end of the v sprin -Tlie spring is compressible to permit t e hook .to swin upward on the pivot 4to engage with an disenglage itself from the roller 2 ofthe keeper. he hook has e straight vertical-"rearedge'and is` provided Hatrthe top thereof with a recess 1n .which the upper lug is arranged. The attachment plate 5 is provided with upper and lower vertical. slots 10.for the reception-of screws `11 for securin the attachment-plate to the verticahadjustment of the' hook tof arrange y roper position 4:for engagement 'with the rol er Qui-the keeper.

The pivoted latch member'ior hook 1 is Vprovided at itsouter end with aninclined edge 12` Yextending downwardlyy and in-y .warcll'yf romthe extremity of the hook and `adapted to lieLearried-by the closing mowe- 'ment of the door into engagement withV Vthe roller 2,-and capabie .ofenablingthe latch door 3. The s ots and the screws permit a member toloe'reeullyswung u ward by such closing movementto engage t ve roller with latch is applied. `The latch, which is. de`

a substantially V-shaped recess, located at the lower edge of the hook. The V-shaped recess forms oppositely inclined edges 13 and 14, which engage the" roller 2 at the inner and outer sldesthereof. The 'outer inclined edge or wall of the lV-shaped recess permits the door to be readily opened, when the proper force is applied, and the inner edge or wall 14 of the Vshaped recess cooperates with the inner wall A13 to hold 1t tightly in its closed position. The opening and closin of thedoor 1s effected without lifting the atch, which is adapted to cooperate withspring'l hinges with which screen doors are Tormanly equipped, and when the door isclosed by suc spring hin es, the latch will automatically engage its eeper and hold the door 1n such position.

' The horizontally disposed roller 2 is mounted on a headed stud 15, suitabl fixedV to an attaching plate 16, provide with horizontal slots 17, receivinlgscrews 18 and adapted to erinit the attac ing plate 16 to be adjuste toward and from the latch. The horizontal adjustment of the attaching plate 16 and the-vertical adjustment of the attaching plate 5 will enable .the arts to be readily mounted on -aV door an the door frame or casing, and with relation to each ot e t n ,The door latch is equi ped with a locking member 19, consisting o a bar or piece havin a substantiall L-shaped4 arm 20 at one en and providedy at its other. end with an inwardly extending lug 21. The L-shaped arm is ivoted betweenthe slots 17 b a in or rivet 22, and the inwardlyexten in ug is adapted to engage over the stud 23 o the member or hook l, as clearlyy illustrated in Fig. 3 of the drawings, whereby the latch member or hook'is held a ainst upward l movement and is prevented rom becoming disengaged from the keeper. The stud 23 is preferably formed b a pin, piercing the hook above the apex o the V-sha d recess and extending from op osite si es of the hook, whereby the latc either right o r left Yhand doors. When the loclcin member 19 is not in use, it hangs down eneath the keeper and is out ofthe llii Figs. 4 to 6 inclusive is illustrated another embodiment of the invention in which the hook 24 coperates with a V-shaped flange 25 of a kee er.` The V-shaped flange referably ormed integlllal with and located) at the top of an attac 'ng late `26, having horizontal slots 27 and a justably secured to 'the door frame or casing by screws 28. y

The latch member o. hook 24 is provided with an outer inclined edge 29, and it has a lower V-shaped recess forming oppositely inclined edges 30 and 31. The inner end of the latch member or hook is provided' at the ylug is plositioned properly is reversible for' plate.
