Another important objectofi the invention yis the provision of a highly emcient; and easily operated catch of the abovev indicated characterI which affords an unusually neat andnnobtrusiveappearance when installed.

Other important objects and advantageous fea-- tures'of the invention will' be apparent from the following description and accompanying drawf ings, wherein for present purposes of illustration only, speci-nc embodiments ot the invention Vare Figure 5 is a view similar to Figure 1 of a modi-V ned form of catch.

Referring in detail to the drawings, and first to Figures 1 through 4 thereof, the numeral t generally designates the free edge portion of a door, shown in closed relation alongside and in line with a door jam-b or the like structure 1, the door being formed with a hole 8 located in spaced relation to the free edge 9. The jamb or the like 'I is provided on one side thereof with a keeper plate lll secured in place by suitable means such as a screw I I and overhanging the jamb edge I2, as indicated at I3.

The catch mechanism comprises a circular nat outer or face plate I4 having an inturned peripheral edge or rim I5 arranged toengage the door surface I6 and space the plate I4 outwardly therefrom, as shown in Figure 1, t0 accommodate 4 claims.

The face plate I4, asshown in Figures 1 and 3,' is formed on a diametrical line with anr outer` diametrically elongatedislot I9 having a rounded outer edge 20, and theinner plate I-I is formed.; onv the same diametrical line; with an outer slot 2l opening through theedge of the inner plate and having an inner square-d edge 22'l located between the ends of the face plate slot If9.

TheY inner plate I=1f is further formed' on said diametri'cal line with an inner slot 23, with an outwardlyV projecting tab 24 extending from the: inner-edge of' the slot 23 and laterally offset tc provide with the subjacent part ofthe face place If4', a pocket for seatingone end of a leaf spring 25, which is aligned with the length ofthe slot:v

23 andv projects outwardly therefrom, as toward the right: in Figure l.

The outer: end portion of the leaf' spring 25 is tensioned against the back or inner edge 26 of a straight bar 21' terminatingl in an outwardly 2l directed hookl 28 arranged to engage over or be- Y bolts 33, 33 traversing the same and terminating hind the keeper plate IIif'or locking the door in closed position. The inner vend of the bar 21- has grooves or notches 29 and 30 in its inner and' outer edges, respectively, to make hinge engagementqwith the mentioned' slot edges. 22 and 20, respectively, the notch 235 on the bar 2l being completed at one side by rounded shoulder 3F arranged to rockabl'y` engage the adjacent outer' or forward side of the inner plate I'I' near the slot edge 22 and retain the bar 21' normally in a position angulated toward the-right, as shown in Figure 1, under the tens-ion of the spring 25. Ihe forward end of the bar 21 merges into a transversely curved handle portion 32 lying close to the face plate I4 but providing ample purchase for lingersV inserted therebehind to draw the handle forwardly and toward the right, and thereby pivot the bar 21 toward the left on the slot edges 22 and 20 and withdraw the hook 28 from the keeper plate I0 to free the door to be opened.

The catch is secured to the door portion 6 by at their forward ends in flared heads 34 received in keyhole slots 35, 35 formed in the inner plate I1, whereby the face plate I4 conceals the bolt heads 34, the material of the inner plate I'I around the smaller ends 35' of the keyhole slots 35, 35 being upset as indicated at 36 to accommodate the bolt heads.

In the form of the invention shown in Figure 5 a hinge pivot arrangement for the catch lever or bar 21a is provided, which includes spaced ears 3'! on the inner plate lla and a pivot 38 carried by the ears and traversing the bar 2M near its forward end. Only one notch 29a is provided in the bar 21a to engage the slot edge 22a of the inner plate I'Ia to limit the Swing of the bar 21a by the spring 25a. In addition, a straight handle 32a, aligned with the bar 21a is provided, which has a knob 40 on its forward end to be grasped in the hand in operating the catch, by swinging the handle 32a toward the left in Figure 5 to release the catch.
