noon CATCH.

Application filed September 12, 1924. Serial No. 737,295.

This invention relates to door catches of the sort having a lever pivoted between its ends, one end of the lever being in the path of the door to check-the closing movement thereof and thereby prevent the door from slamming noisily or violently, and, the other end of the lever being adapted to engage the outside of the door to complete its closing movement and to hold the door in tightly closed position, a spring being associated with the lever so as to throw the same to its extreme positions. Door catches of this sort are used in connection with spring closed doors such as, for instance, screen doors.

The aim of the invention is to provide a door catch of this sort having various fea tures of novelty and advantage, and which is particularly characterized by its neat and pleasing appearance, by its simplicity in construction and economy in manufacture, and by its durability and effectiveness in opera tion. 7

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the'appended claims.

In the accompanying drawings, wherein I have shown, for illustrative purposes, one

embodiment which the present invention may take Figure 1 is atop plan view of the device associated with a door shown in horizontal section;

Fig. 2 is a front elevation thereof;

Fig. 3 is a view taken longitudinally and centrally through the device, the lever being shown in door checking position;

Fig. 4 is a transverse sectional view taken substantially on line H of Fig. 1; and

Fig. 5 is an elevational view of the member to which the spring is anchored.

Referring to the drawings in detail, A denotes a casing or support; and B, a lever pivoted between its endsto the support and having at one end a roller C which the door is adapted to strike as it swings into closing position, as shown most clearlyv in Fig. 3. The other end of the lever carries aroller D adapted to engage the outside of the door to complete the closing movement thereof and hold the sametightly closed. E is a spring connected at one end to the lever B and at the other end to a bracket or anchor F and so arranged as to snap the lever to each of its extreme positions. The letter G designates rivets which connect the bracket F to the support A. In Fig. 1, the support A is shown as being secured to a door casing H adjacent the swinging or free edge of the door, the latter being designated by the letter I.

The support A is preferably formed of sheet metal by stamping out a blank of the desired configuration and then bending and drawing the blank to the shape shown. The support is generally U-shaped in section and has generaly parallel side walls 10 and a connecting or end ,wall 11, the lat ter being longitudinally curved to corre spond. generally to the longitudinal curva ture of the lever B. The support may be secured to the door casing in any suitable manner and, to this end, it may be provided with flanges 12 aperturcd to accommodate securing screws 18. The forward or outer end of the support is provided with alined apertured bossesfl l which, together with complementary bosses 15 on the bracket F, constitute bearings for the lever B. The bosses l4 and 15 are preferably formed by punching holes inthe metal and bending the metal about the holes-outwardly or inward- 1y, as the case may be. The openings 16 in the bosses 14, and the corresponding open ings 17 in the bosses 15, are non-circular. They are, preferably, square, as shown, and the rivets are likewise square so to prevent relative movement between the bracket F and the support. The bracket F, which is also, by preference, constructed of sheet metal stamped and bent to proper shape, is in the form of a U or yoke, and the connecting portion 20 of the yoke is provided with an apertured tongue 21 to which is at tached one end of the spring E.

The lever B, which is, preferably, formed of a single piece of sheet metal, is longitudinally curved so that it is somewhat crescent shaped. As breviously stated, the longitudh nal curvature of the lever corresponds generally to the curvature of the end wall 11 of the support so that the device presents a neat and pleasing design. The lever B is also transversely curved, that is to say, it is gcnerallyli or channel shaped in cross section. The side (i. e. top and bottom) walls 'nated by the numeral of the lever are tie 25, and the trontiw. The side walls, are provided. with aiined apertures 27 which receive the bearings formed by the cooperating bosses l4 and 155 The roilerC is preferably formed of re silient material, such as rubber, andls ournalled on a shat'L QScarried by ears29exend ot the lever. The rlyf'journalled on a shaft 3i at tliefot he'r end of the 1 initiatesmovement oi the lever B" frorn 'the" position si own in 1, and, atte'rfth-e spring has, been thrown past dead center, t snaps the lever to the position shown m Fig. 3., When the door ,is swung 7 into closed po-' sition, it engages the roller (1, as shown in Fig. 3, whereupon the closing movement of the door is checked and violent slamming.

thereof is avoided. 'The door, continuing its closing movement, will swlng the lever counter-cloclqvise and, after the spring has been thrown past dead center, it will'snap' the lever to theposition shown in Fig, 1, thus insuring that the door w llbe brought to fully closed position and heldfin that position.

It will be observed, and particularly from Fig. 2, that when viewing'the d'evic'e'in front a a a elevation, the spr ng E and the bracket 1* are entirely concealed by the lever B" and that thatend of the lever .carryingtl'ie roller C is housed within and concealed .by the support A. Thus, thereis only exposed to,

view the rounded portio rof the lever, the support A, and a portion of th'e rolier D., The lever B which, by preference, is one integral piece, may be tactired from wrought lsl for holding the'plates tog tl er .beingle'n tirely eliminatet, The bearings for the lever are cheaply iormed, the parts oft-he bearings may be readily assembled together, and wear ,upon the bearings is negligible, As previouslypointed out, the mernber F, in addition to constituting, in part, bearings for the lever,.also serves as an anchor for one end of the spring E. The Structure comprises but relativelyfew parts, ach of which, may be manufactured at a relatively low cost, the parts may be readily assembled together, and these parts are Partieularly strong and durable' so that the. catch will have a relatively long 'life.'

As many changes could be made in the l by the numeral '26,
