To all whom 'it may concern;

Be it known that` I, Jol-IN L. Zrisronn, a

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Screen-Door Catches, and do declare that the `following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to screen door catches,

all. substantially as shown and descrbedand particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of the catch mounted on a door and in engaging position, and Fig. 2 is a side elevation thereof showing the catch in disengaged position, the door and door casing being shown in section in both views. Fig. 3 is a sectional elevation lengthwise eorresponding to line -ag Fig. 1, the narrow side of the casing being removed to disclose inner parts. Figs. 1 and `5 are views looking in froin the bottom of the device and showing the lock for the catch proper in two dif` ferent posit-ions as hereinafter described.

Fig. 6 is a perspective detail ofthe catch, and Fig. 7 is a perspective view of the bracket supporting the saine in the casing.

The invention as thus shown is simple in both construction and operation and is designed to provide a catch for screen doors particularly, though it may be used for other doors as well, because it is desirable to have a screen door respond to a direct pull or push so as to open as if it were not inechanically engaged in any way and without usi-ng the hand to release a catch, and the present catch answers this purpose while at the same time it is also essentially a catch for the door which can be locked, as will hereinafter more fully appear. Thus, A represents the casing containing the catch C and other parts and adapted to be aiiiXed to a door, gate or the like by screws as usual in like devices, and having certain novel details of construction including lugs 2 struck inward from its ends adapted as rests for spring S, and a slot -3- in its inner side through which the finger piece 4: of lock L for the catch projects.

The essential novelty of the invention is found more especially in catch C, and the peculiarity and originality of said catch as coniparedwith allcthers with which I ani familiar involves a construction adapting `the saine to both swing and slide within liniits on a single set` of" side projections or pivots 8. Incident to these pivots is the curved projection 10 on `the engaging edge of `the `catch substantially inidway between its ends Iand adapted `to `throw the catch back out of engagement withfthe latch 14- onthe door casing when a push or pull is made upon `the door to open it and thus automaticallyrelease `the catch ,from said latch lll.

.Ie Weil `be eeeieeeleeee ieee eeeeeeeeeee occurs between Athe catch and latch when the door is shut, but whenany one passes in or outa pull or a `push on the door springsthe catch black,the action being `first a direct pull on the catch and then instantly followilie' .e Sir-ine backward thereof by reason 0f curvedprojection 10 striking the end edge 13 of the slot in the side of the casing through which the Catch projects. Norinally said projection lies just inside against `said edge as in Fig. 1, and when the door is the catch is disengaged from latch lei substantially as in Fig. 1, when the door opens.

The catch is supported by a bracket B which .llfls OPQEU bel'llgs Olf SlQtS b in its angle adapted to receive" the pivot projections 8` on the catch, the catch lying between the sides of said bracket. The spring S bears constantly against the inner end of the catcli which has an eccentric portion or projection 15 on which the catch turns when swung from engaging to disengaging position7 F ig. 1 to Fig. 2, and which lifts the pivots 8 in slots Z) correspondingly.' When pressure is brought against the door so as to exert pull on the catch suoli pull is first against spring S. As this occurs the curved projection 10 strikes the end edge `13 of the slot 16 as above described and forcibly throws the catch back frein engagement with projection 1li, Fig. 1, to releasing position, Fig. 2. Then the instant that the door is opened spring S asserts its control of the catch and throws the parts back to normal position. The catch closes automatically by striking its curved back 18 against projection 14e and springing into engagement therewith on the other side and holding` the door closed. The play of catch C, is, Jttherefore, automatic in both opening and closing the door I), and its positions are the same relatively in both opening and closing, the only diierence being the point of operation.

Further details as to catch C are its depressions or recesses 2O in the sides thereof in which sliding lock L is adapted to engage by one of the side arms of its substantially T shaped projection 22 when the catch is to be locked back out of possible engaging position, Fig. 4. rIhe said projection 22 is also adapted to be placed at middle and edge directly against the catch when it is to lock the catch in engaging position with the latch by bearing directly against the same as in Fig. 5. Operation of said lock is from the inside of the door by projection 4 thereon and a spring 24 rictionally holds the said lock in adjusted position. rlhe said lock,

Vfurthermore, is adjustable to engage either side of the catch in its recess 20 according to the position the catch occupies on a door. Suppose it be set vertically lengthwise. It is desirable in that case to have the projection 22 set to work from below so that the lock will have to lbe lifted to locking position and will not be in position to gravitate or work to such position by jarring of the door. Practically Yit is better to have it where it will work open rather than closed. Hence I have made the said lock adjustable so as to always have it below whichever end of the device is set above. Such adjustment is eected through the spring 24 which carries finger projection 4 and which projection is adapted to slide in the slot Z in lock L as spring 24 is adjusted endwise to change `from one position to another and engaged in such case with the corresponding lug d on the respective ends of said lock. A hole is made in each end of spring 24 adapted to slide over and engage on said lug, as seen in Figs. 4 and 5. Friction between said lock L and the casing on the inside and by linger projection 4 on the outside induced by spring 24 holds the lock in any position to which it may be moved.

What I claim is l. In door catches, a casing and a catch therein having a single pair of pivots at its inner end and a spring bearing against said end, a bracket in said casing provided with open slots for said pivots, and said catch having a curved projection adapted to engage the said casing and cause the catch to swing on said pivots and slide in said slots.

2. In door catches, a casing and a substantially right angled bracket therein having open slots in its angle, in combination with a catch engaged in said slots and having a curved inner extremity behind said pivots and a reversely curved projection at its middle adapted to engage the said casing, and a spring bearing against said curved inner extremity of the catch.

3. A door catch and a casing having a slot through which said catch projects, a bracket fixed in said casing having the said catch slidably and pivotally mounted therein upon a single pair of projections, a spring engaging the inner end oi said catch and Ysaid catch having a curved projection between its ends adapted to engage the said casing next to said slot and cause the catch to swing on its pivot projections.

In testimony whereofl I sign this speciiication in the presence of two Witnesses.
