v6 claims. (c1. 292-75) This invention relates to roller catches of the type, which includes a spring-pressed roller and is commonly used with a strike Ias a latch for an interior door. More particularly, the invention is concerned with a novel roller catch made of a few parts which can be produced by simple manufacturing operations and can be readily-assembled to form the catch. The new roller catch operates smoothly without sticking, and it is subject to little wear and not liable to be damaged in use.

The roller catch` of the invention comprises `a housing of channel section having a closed rear end and laterally extending ears, by which it can be attached to a door, for example. A slide of channel section is mounted in the housing for longitudinal movement and the slide extends out of the front end of the housing and carries a roller mounted for free rotation on a pin secured in the side walls of the slide. The slide is providedwith laterally extending lugs received in'slots in the side walls of the housing and guiding and limiting the movement of the slide. The slide is urged to its extreme outer position by a springv bearing against the slide and the rear Wall of the housing.

For a better understanding of the invention, reference may be made tothe accompanying drawing in which Fig. 1 is a view of the new roller catch in per b spective;

The roller catch of the invention comprises a housing generally designated Ill and shown as of inverted U-section. .The housing includes side walls II lying parallel to each other and a rear end Wall I2 between the side walls, the side and end walls being integral with a top wall I3. The front end and inner side of the housing, that is, the end from which the slide protrudes and the side which is attached to the door or other surface, are open and the housing is lprovided with ears I4 extending outwardly in a plane from the lower edges of its side walls. The ears are formed with slots Ma for receiving screws I5, by which the roller catch is attached to a door D, for example. The side walls II of the housing are formed with aligned llongitudinal slots IIa.

. A slide generally designated I6 is mounted within the housing and projects outwardly through theopen end thereof. The slide'is of inverted U-section and includes a'top wall-@I1 and parallel side walls I8. A pin I9 is mounted in openings in the side Walls I8 near the `outer ends thereof and outside the housing and a roller 2l), which is preferably made of rubber, is mounted for free rotation on the pin. The endsof the pin are headed, as indicated at I9a, to hold itrmly in place. Y i

Toward the rear end of the slide, the side walls are of reduced width and each wall is provided with an integral lug 2|, which is receivablein a slot IIa in one of the side walls II of the housing. About midway between the ends of thetop wall of the slide, va tongue 22 is struck inwardly therefrom and the free end 22a of the tongue is bent toward the rear end of the housing. l A coil spring 23 lies within the slide and bearsfat its forward end against tongue 22, the spring encircling the end 22a of the tongue. A tongue 24 is struck inwardly from thev rear end wall I2..of the housing and the rear end of the spring bears against the rear end wall I2 and is caught behind tongue 24, so that the spring is properly centered.

As is shown in Figs. 3 and 4, the width of the slide I6 from the plane of the lower faces of lugs 2I- tothe plane of the lower surfaces of the side walls I8 is less than the distance from the plane of the lower surfaces of slots I Ia in the sidewalls of housing `Ill to the plane of the lower faces of ears I4. As a consequence, the slideis supported by lugs 2I in slots IIa with the inner end ofthe slide spaced from the surface, to which the roller catch is attached, and, as the slide moves in `and out of housing I IJ, it can not tilt sufciently to bite into or damage the surface. The slide, accordingly, moves in and out of the housing freely and with little friction. Y

`'The housing and slide are made from sheet metal and the housing is formed in a single stamping operation. At the completion of this operation, the side walls II of the housing :lie sprung outwardly to a. slight extent. The slide is made in a single stamping operation and it is completed by the mounting of the pin and roller thereon. To assemble the roller catch, the spring is inserted into vthe housing and its rear endis caught behind tongue 24. The slide is then inserted into the housing with the end 22a of its tongue 22 entering the front end of the spring. Although the overall Width of the slide across tongue 2| is greater than Ithe distance between Walls II of -the housing of the completed slide,

the insertion of the slide into the housing can be accomplished because the side walls l I of the housing are sprung outwardly, as described. After the slide has been inserted into the housing against the resistance of the spring and the lugs 2| are aligned with slots Ila, in the side walls of the housing, the side Walls Il are bent toward each other Luntilf they lieparallel.` `fAsga result of this operation; the lugsr2l on theY slide enter -the slots lla and the slide is held positively within the housing, although it is permitted a longitudinal movement equal to the diierence between lengths of slots Ha and lugs 2|.

In the use of the new roller catch, the slide is forced inwardly against the compression ofthe spring when the roller rolls over the strike. As the lugs 2| on the slide make contact over relatively long areas with the walls'or slots `l'la'ofthe housing, the cooperation of these partsfinsures that the movements of the slide in opposite directions will bep-along a rectilinear path and the slide cannot tiitsiifcieiuy to'cause either end thereofto bemoved tov afp'osition .beyfmdthe plane of the inner side of the housing. Hence,

the slide cannotbi'te Yinto or engage the: surface to which the roller catch isattached 'and will always-move freely'without any sticking or binding.
