PUSH CATCH y FOR DOORS.

*Application `led July 16,

Our invention relates to a push catch for doors and the subject matter herein disclosed and claimed is kan yimprovement on the push catch for doorsk that forms the subject mattei' of our co-pending application for U. S. Letters Patent filed March 25, 1926, Serial No. 97,193. -The principal objects of our presentinvention are to lgenerally improve upon and simplify the construction of the latching'device that is set forth in our 'aforesaid co-j pending applicationas well as otherexisting forms of similar devices; to provide a push catch-that is especially applicable for use on the doors of cupboards, closets, medicine cases, book cases, and ythe like; tol provide a structurethat maybe readily adjusted to permit of its being easily and quicklyfinstalled ondoors of different thicknesses; and further, tol provide a latch of the character lreferred tothatV may be used in connectionwithplain or ornamental knobs of wood, glass, metal, porcelain, or composition.

With the foregoing and other objects in view, our invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed andillustrated in the accompanying drawing, in which- Fig. 1 is a vertical section taken lengthwise throughthe center of a push catch of our improved constructionand showing the samein position f or'use upon a door.

Fig. 2 is a sectional view taken on the line 2.-2 of Fig. v1.

Fig. 3 is a vertical sectionV taken on the line 3 3 of Fig. 1. ,Y

Fig. 4 is a horizontal section taken on the line4-4of Fig. 1. Y i

Referring by `numerals to the accompanying drawings whichillustrate a practical embodimentV of our invention,'.10 designates a door and 11 a shelf or partition to therear of said door, and for-the accommodation of our improved latch a relatively small circular aperture such as 12 isformed through the door in a'horzontal plane below the plane occupied by the underface of the shelf or partition. Secured to the underside ofthe shelf or partition a short distance rearwardly fromits front edge and in, line with the aperture 12 is a catch member 13 having a depending finger 14.

Positioned lagainst the inner face of door 10 below fthe.. opening 12 is a narrow verdriver orlike tool. [of tubular stem 26 is practically the same as inwardly from 31 and arran i926. serial No. 122,820.

tically disposed plate 15, the upper portion of which overlies the inner end of the aperture12 and formed integral with the upper portion of this plate and projecting into said aperture 12 is an externally `threaded tubular member 16.L j

Plate 15 isr secured to the door 10 in any `suitable manner, but we prefer to make use of a single screwv 18 that passes through an aperture inthe lower portion of said plate y and said screw being-seated-in the body of the door. Formed integral with the sides of plate 15 are parallel ears 19- and seated therein is a pivotpn 20 that passes through the rear or mner portion of a horizontally disposed latching member 21.` vThe forward or'outer end of this latching member is provided r.x'lvith' an upwardly projecting hookl 22 that is adapted,`,when the door is closed, to engage behind the depending finger 14 of catch member 13. Formed integral with the rear or inner portion' of latchingA member 21 is an upwardly projecting'plate 23; and formed in the upper portion thereof is a short vertically disposed slot v24.w Screw-seated on that portion of the tubular member 16 that projects into aperture 12, is the internally threaded portion of a tubular stem 2 6 that projects al substantial distance outwardly from the outer face` of the door '10.

The outer end of this tubular member 26 is provided with a head 27 inthe outer face of which is formed a slot y28 that is the point of a screw adapted to receive The external diameter the diameter of opening 12.

tubular member 16 iS ya `push rod 29 and formed on the outer end of this rod is a button 30. Formed on rod 29 a short distance the button 30 is a. shoulder ed on said rod and bearing against this 's ioulder and against the end of tubular member 25 is an expansive coil l f spring 32.

The inner end portion of rod 29 is threaded as designated by 33 and mounted' on said threaded portion is la small blockf34 from the sides of which dependears 35y that overlie the upper portions of ears 19. Seated in the depending ears 35 are the ends of a pin 36 and said pin passes through short hori- `zontally'disposed slots 37 that are formed in j the ears 19 and said pin also passes through the slot 24 that is formed in the inner end portion of latching member 21.

The block 341, after adjustment upon the threaded portion 33 of push rod 29, may be- Vsaid hook and the operating partsof the latch being held in the positions shownrby the expansive power of spring 32 acting on rod 29. l l

To release the 'catch in order to open the door, the knob 38 is engaged between the first and second fingers of the hand 4and the .thumb is pressed against button 30, thereby moving rod 29 inwardly against the resistance oflered by vspring 32. As .the rod is ythus moved inwardly, the pin 36 that is carried by the depending ears 35 of block 34: will traverse the horizontal slots 37 and the bearing of the pin Siagainst plate 23 at the front edge of notch 2a will swing the latching member 21 upon its pivot pin 20, thereby moving the free end of said'latchingjmember downwardly and disengage hook 22 from finger 13. i

The door may now be opened and when the pressureof the thumb on button 30 lis relieved, spring 32 will act to restore the operating parts to their normal positions.v

When the door is again closed, the hook 22 on the free end of latching member 21 will strike against finger 14 and pass downwardly beneath said finger and immediately, under the influence vof spring 32, latching member 21 will swing upwardly to its normal horizontal position so that hook 22 will re-engage behind depending inger 14, thus latching the door in nclosed position.

Tubular member 26`may beadjusted inwardly or outwardly upon tubularmember 16 for the accommodation of'knobs of different lengths and block 34 may be adjusted upon the threaded portion 33 of rod 29 in order to control the positio'nof flatching member -21 and also to control the length of its vertical swinging movement. Y

In applying our improved latching device toa door, it is only necessary to bore a single small hole in. said door and lto set only two screws, oneof which fastens plate 15 to the inside of the door and the other fastening plate 13 to the shelf 11.

A particularlyl desirable feature of our latchistheV arrangement of the hook 21 and hook actuating parts 34, 35, and 36 wholly beyond the inner surface of the door to which the device isapplied, for by such arrangement it is not necessary to notch or rethe door for the accommodation of the parts just mentioned.

A doorlatchofour improved constructionv is comparatively simple, may be easily and quickly installed, may be readily adjustedA so as to be'applied to doors of different thicknesses, and is adapted to receive practically all sizes'and designs of' ornamental l knobs. 4

It will be understood that-minor changes in the size, form and construction ofthe various parts of our improved door latch may be made and substituted for thoseherein shown andl described' without departing from the spirit of invention, the scope 'of which isset forth in the appended claims..

`We claim as ourinvention: Y 1.
