EDWARD w. WEILAND, or FRESNO, CALIFORNIA,

DOOR LATCH AND BUMPER.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed December 5,1917. Serial No. 205,499.

To all whomit may concern:

Be it known that I, EDWARD \V. WEILAND, a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented new and useful Improvements in Door Latches and Bumpers, of which the following is aspecification.

The present invention relates to improvements in latches for screen doors.

The object of the invention is .to provide in a screen door. which can be closed by means of spring hinges, means for preventing the slamming of the door, and means for latching the door either when it is quite closed or when, owinoto such preventive means, it is not quite (dosed but closed sulficiently to exclude the flies.

A further object is to provide a device of this character which can be installed very easily and cheaply and without employing skilled labor for thepurpose.

In the accompanying drawing, Figure 1 is a broken horizontal section of a door and the jamb therefor, showing my improved latch and bumper in plan view in one position thereof; Fig. 2 is a similar view showing the same in another position; Fig. 3 is a broken sectional view of the door, showing the latch in bottom plan view; Fig. 4 is a horizontal longitudinal section through the latch; Fig. 5 is a broken side view of the door showing a latch and bumper thereon; Fig. 6 is a broken perspective view of the latch detached; Fig. 7 is a perspective view of the bottom of the casing detached; Fig. 8 is a similar view of a striking plate; Fig. 9 is a similar view of a lock.

Referringto the drawing, 1 indicates the jamb of a door 2, having its outer. edge rabbeted, as shown at3, to receive the free vertical edge of the door. To said jamb is secured a striking plate 4, having a portion nearest the door rounded, as shown at 5, to receive the impact of a striking plate and having a vertical edge 6 adapted to engage a latch 7 of the door to hold it closed. 8 indicates a latch casing of sheet metal, the central portion 9 of which is of an arch-shaped form and which has flanges 10 attachedby screws 11 to the door 1. The latch casing 8 forms the principal member of a guideway for a latch, the remainder of the guideway being formed by a bottom 13, also formed of sheet metal, and secured within the archshaped portion of the latch casing by means of lugs 14 extending out therefrom and through pairs. of slots 15, 16, in opposite sides of the latch casing, the hole 15 being longer than the holes 16 to enable the lugs 14 to be inserted therethrough from the inside of the casing, said lugs extending downward against the walls of the latch casing to hold the casing from spreading, should the screw '11 be improperly inserted and not hold firmly in the door.

The latch 7 which slides within the latch casing is formed of two sections 17,18, of sheet metal, forming the respective sides of the latch, and having extensions 19, which are riveted together, as shown at 20, and have'beveled advancing edges 21 adapted to impinge against the rounded portion 5 of the striking plate as the door closes. Said extensions 19 can slide in an open-ended slot 25 in the middle of the front end of the latch casing 8. The front end of the horizontal portion of each section is formed with an angular recess 22, said recesses constituting a hook adapted to engage the free vertical edge 6 of a striking plate to cause said latch to be retained by said striking plate when the door is nearly closed. The inner edges of the horizontal portions of said sections constitute in effect another hook 23 to en gage said free edge to retain the door when it is closed tight.

To withdraw the latch, the edge ofthe upper one 17 of said sections adjacent to the other section is recessed, as shown at 24, through which, and through slots 26, 27, in the bottom 13 and casing 8 respectively, extends a latch lever 28, which can also abut against a lug 48 bent up from the upper section at the rear. end of said recess. Said latch lever 28 also extends through a hole 29 .in the door, and through a hole 31 in a plate 32, the ends of which are secured by screws 33 to the outer side of the door, said platebeing bent toform apull adapted to be engaged by a finger to open the door from the outside.

. The slot or recess 24 for the latch lever is located at one side thereof in order to make room for a coiled spring 34, of which the rear end is secured to a lug 35 cut out and bent from the latch, while the other end is secured to a hole in the front end of the bottom 13. This spring always returns the latch to-its locking position when released from the lever.

Said latch lever is formed of a single long and narrow piece of metal folded along a tion of said lever. 1

l/Vhen it'i-s desired to lock the latch in a position retaining the door closed, there is provided a lock 39 having a shorter leg 40. and a longer leg 41, and bent over at its vupper end, as shown at- 42', to provide a finger piece. Said legs 40,41, slide through holes in the upper side of the arch-shaped portion of the latch guide close to the upper flange, and the longer leg 41 also slides through a 1 hole close to the lower flange in-the lower movement.

i 49-extendingfrom thelower edge of said side of said arch-shaped position, and is then bent outwardly, as shown at 45, to retain the lock in place; Said longer leg guides the lock in its vertical reciprocating hen the lock is pushed in, however, the shorter le '40 then extends immediately to the rear ot the latch lever when in its forward or locking position, so that said lever cannot be drawn back to withdraw the latch from its locking position.

= The holes in the upper side of the archshaped-casing through which the legs 40, 41, pass are spaced from each other at such a distance relative to the distance between the legs 40, 41, that, when the lock is pushed outward, said legs are pressed toward each other, the friction thereby caused tending to retain the lock in its upper or inoperative position against gravity.

There is also provided a bumper 43 of rubber, secured to the free end of an arm 44"pivoted by a screw 46 on the door immediately above the latch casing, so that, when the bumper arm 44 is in one position, a lug arm abuts against the upper side of the upper "flange 10 of said casing, and said bumper is then in a position intervening between the jamb and thedoor when the latter is closed. When the upper arm is-moved in the opposite direction a lug 50 extending from its-other longitudinal edge rests upon, sa d flange and the bumperv then no longer thus intervenes and is inoperative. A washer 47 intervenes between the arm 44 and the door to prevent the arm 44 wearing against the door.

The bumper 43 is attached to the arm 44 by a screw 48, so that when worn out, it can readily be replaced by a new one.

It will be observed that but one rivet is employed, namely, the rivet 20, and that otherwise the device is made wholly of sheet metal :bent to the proper form, and can be attached in place with the greatest ease.

I claim 1. In combination with a door and a j amb therefor, a :bumper attached to one of said elements so as to be movable into positions in'which it is respectively operative and inoperative to resiliently resist the closing motion of the door, a striking plate on the vjamb, and an automatic latch on :the door for engaging said striking plate, one ofsaid co-engaging elements being provided with means forengaging the other in either of two latching positions corresponding to the operative and inoperativepositions of the bumper.

,2. In combination with a door, a latch casing secured thereto, a latch slidable in said casing, a latch lever for operating said latch, and a lock for locking said latch lever having abent portionforming a finger piece, a long guide legextendingthrough holes in the walls of the latch casing, and a short locking leg extending through ahole in one wall thereof, said short leg being adapted to move immediately to the rear of said latch lever in its locking position to maintain it locked.

In combination with a door, a. latch casing securedjthereto, a latch slidable in said casing, a latch lever for operating said latch, and a lock forlocking saidl-at'chlever having abent portion forming/a, 'fi-ngerzpiece,

Copies of this patent may be obtained iorfive cents each, by adglressingthe Commissioner of Patents, I Washington, ILQ."
