Application med march 13, 191e. serial No. 83,852.

To all 'whom it may concern Be it known that 1, CHRISTIAN EvENsEN, a subject of the King .of Norway, residing at Choteau, in the county of Teton and State of Montana, have invented a new and use'- ful Door-Catch, of which the following is a specification.

My invention is intended for use on doors of cabinets, cupboards, and the like, and the Aobjects of my improvement are to provide a device which will firmly secure a door by the simple act of pushing'it shut, and which will unfasten the door'by the simple `act of pulling outwardly on the knob, thus making unnecessary 'either a twisting or a sidewise motion on the knob before pulling outwardly.

A working parts inside.

A practical form of my invention as applied to a cupboard having doors and shelves of wood, is illustrated in the accompanying drawing. However, the device is equally as Well adapted to cabinets, cases, etc., made of metal.

Referring to the drawing: Figure 1 is a front view of a small portion of the two doors with knob and escutcheon in place. Fig. 2 is an inside View of the same small portion of the doors, with the shelf removed to Vclearly show parts which attach to the doors. Fig. 3 is a View looking upward, being partly insection, taken on the line m-w of Fig. 1, and showing doors closed and catch holding. Fig. 4 is a View taken the same as in Fig. 3, but showing doors unfastened and the right hand -one slightly aj ar. Fig. 5 is an enlarged side view of the door-plate and plunger assembly, shown as detached from the door and viewed in the direction indicated by the line y-y of Fig. 2. Fig. 6 is a sectional side view taken on the line z-z of Fig. 4.

Similar indices refer to similar parts throughout the 'several views. The main body. of the door-plate 2 forms the inner guide for plunger'l and has holes for 'attachment to door with screws or by other means. In addition, plate 2 has two bent projections, the hook c and the part d, which form the front guide for plunger l and act also as the frontl rest for push- 'spring 12. The rear end of spring 12 pushes 'against washer 11 and pin 10, which latter Specification of Letters Patent.l

-is disposed through the plunger and projects 'a' 'little on either side. Spring 12 is quite light, belng just strong enough to retain plunger 1 at its inner limit, with pin 10 resting against the plate 2. The main part of plunger 1 is shown to be square, but the smaller part g, extending from the shoulder k forward, is round and has the forward .end threaded for attachment of knob 5.' Shoulder h, by striking against the rest d just as the inner end of l comes Hush with the inner surface of 2, serves as a limit to prevent pullig plungerl 1 too far. The plunger assembly is shown as fitted to door 20. The escutcheon 6 serves only as an ornament, and may be made in any suitable shape or artistic design.- Likewise the knob may be made in various designs. The eyepiece-4 is attached to door 21.

The double-leg catch piece 3 is pivotedA (by rivet' 8) tothe central', circular, raised portion of the plate 7, which latter is attached to the' under side of shelf 22. Plate 7 has also two projections, the lug e which serves 'as a stop to .limit the backward rotation of piece 3, and the lug f, upon which one end of torsion springt) is hooked. This spring is very light, and is disposed around the central raised portion'of 7, and has yits other end hooked over the edge of leg a.

Fig. 3 shows the doors fastened. The toe` of leg Z1 projects through the eye of piece4 and the toe of leg a is retained in hook c by means of the plunger 1.. Now, by simply pulling onknob 5, the plunger 1 first clears the heel of leg a, then the pull of the hook 0 Yon top of the toe a rotates the piece 3 back out of engagement to the position shown in Fig. 4. Spring 9 is just strong enough to retain 3 in this position whenever the doors are open.l It is obvious thatthe pull necessary to open the door .is utilized to unfasteny the catch, and that the need of either a twisting or a sidewise motion on the knob is eliminated.

' action is considerably to one side of the pivot point 8, causes the toe .of a to move readily into hook c. and piece 3 to rotate about the pivot. During this movement of a in entering the hook c, plunger 1 is forced back against the action of springl 12, until the door closes and the toe of a is clear back in be left olf. These parts are most needed in.v

those cases Where the door 20 does not overlap door 21. It is plain that when used on a pair of doors, my invention 4takes the place of both elbow-catch and cupboard-tu`rn or catch, and that the lnumber of motions used in opening the doors is appreciably reduced.

I claim: Y

In a door catch, a foot-sha`ped arm, being pivoted at its inner end to shelf or case, and having its longitudinal center line disposed incense closed, the inner` end of the plunger strikes the arm near its outer end, the, aforesaid oblique disposal of the arm, together with the closing movement of the door, causing the arm to engage the hook, in which engagement thearm and the hook are retained by the plunger, all substantially asvdescribed for the purpose specified.
