HASP FASTENER WITH ALIGNING TONGUES Original Filed Feb. 24, 1941 INVENTOR A ORNEY Patented Feb. 25, 1947 HASP FASTENER WITH ALIGNING TONGUES Albert J. Komenak, Stamford, Conn, assignor to The Excelsior Hardware Company, Stamford, Conn, a corporation of Connecticut Original application February 24, 1941, Serial No.

380.294, now Patent No. 2,374,687, dated May 7 1, 1945. Divided and this application May 20, 1943, Serial No. 487,741

3 Claims.

' Thi invention relates to hasp fasteners for drawing and holding firmly together separable wall edges of hinged-together container parts, such as the body and lid of an article of luggage, a tool box. a trunk or the like, and particularly of the type which incorporate a hollow keeper providing a draw shoulder. The keeper is usually adapted to separate with its container wall from another section of the fastener incorporating a frame jacket which serves as mount for a toggle operated draw hasp adapted to engage and pull upon the keeper.

A lockable hasp fastener of this type is disclosed in my earlier Patent No. 1,652,676, and also in my copending application, Serial No. 880,294- filed February 24, 1941, now Patent Num- 'bemwmfifi'mgranted May 1, 1945, from which the present application is divisional. The present improvements aim to make certain parts of the earlier fasteners stronger and more eifectively operative in bringing about and maintaining accurate alignment of the before mentioned separable edges of the container parts.

One object of the invention is to produce a keeper having a doubled-over or folded-back projecting dowel tongue comprising an integral extension of a dished sheet metal structure forming the keeper and providinga draw shoulder engageable by the hasp.

Another object is positively to anchor the draw hasp to the draw shoulder of such a keeper for the double purpose of preventing accidental separation of these parts and further helping to insure a detentive overcentering action of the hasp operating to le lever when the fastener is closed. .A further object is to provide cooperative camming surfaces on both the dowel tongue'and one. portion of the frame jacket which borders a receiving aperture for the dowel tongue.

. The'foregoing and other objects of the present improvements will appear in greater detail from the following description having reference to the accompanying drawings, wherein: Fig. 1 is a front elevation of a lockable hasp tastenerincorporating the present improvements.

1 Fig. 2 is an edgewise view looking from the left at Fig. lshowing a portion of the container parts held together by my improved fastener.

Fig. 3 is a view drawn on an enlarged scaletaken in section on the plane 3-3 in Fig. 1 lookingin the direction of the arrows.

. Fig. 4 is a fragmentary view of the dowel tongue drawn on azlarger scale than in Fig. 3. Fig. 5 is a view taken partly in section on th 2 planes 5-5 in Fig. 3, looking in the direction of the arrows.

Fig. 6 is a view taken partly in section looking in the direction of the arrows 6-6 from the plane designated thereby in Fig. 2. I

Fig. '7 is a view taken partly in section look ing in the direction of the arrows 1-1 from the plane designated thereby in Fig.2. 7

l0 and H represent respectively the body and lid walls of a trunk or other article of luggage, or of any container having a hinged cover or closure such as a mechanics tool box or the like. The keeper structure I 2 is in the form of a hollow or dished section of'drawn sheet metal which includes a shallow marginal or mounting flange I3 adapted to be secured to lid H by rivets or screws l4, and also a hasp anchorage portion [5 affording a keeper shoulderwhich contains the anchorage aperture 16 entered by the anchor tongue of the hasp, as hereinafter more fully described, so that the hasp becomes anchored at a fixed point in the keeper. A projecting portion of the front Wall of hasp anchorage l5 curves inward and downward and itsterminal length is doubled over or folded back upon itself to form the dowel tongue I! as best shown in Figs. 3 and 4. That part of tongue 11 between its foldedover bottom extremity and the front wall of keeper portion I5 presents a concave camming surface for purposes which will appear hereinafter. The folded-over bottom extremity, itself, forms a convex'camming surface. and concav zsurface'smeet and merge to forms; continuous smooth ogeescurve as is evident from Fig. 4.

The mountingor-escutcheon frame 20 consists of a shallow dished plate formedfrom sheet metal and adapted to be securedto container body It] by screws or rivets 2|. ed by member ZOisOccupied by the casing 22 of a lock mechanism designated as a whole by 23. This lock mechanism may be'of any desired construction, as'forinstancethat shown in Fig.- 9. of the drawings of mysaid copending application, and therefore will not here be described in fuller detail.

A key barrel has'itsfront end 21 reduced-in diameter and rotatably supported in an aperture 28, containedin theJfront wall 29 of a frame jacket '39 whose side walls 3| at their bottom",

terminalssupport oppositeends, respectively, of a. hinge pines. Side walls Stare each extended to form a pair of elongated tangs 3 3 which pro' ject not onlythrough closely fitting slots in the escutcheon plate '20 butcontinue rearward These convex.

The concavity aiiord-' past the shallow depth of lock case 22 and on through close fitting slots 35 in the rear wall of the latter. Against the backsurface of case 22, tangs 33 are swaged over as means for holding solidly against escutcheon plate .20, both the frame j acket 30 and lock case 22, on respectively front and .rear

sides of the escutcheon plate.

;will be seen that shelf ll by engagement with Inside of frame jacket 30 a retainer plate 34 assists in supporting and retaining the key barrel,

having for this purpose a bent :metal formation most clearly shown in Fig. 5. The top .of the front wall 29 of jacket 30 is turned rearward .toIform-a shelf 4| inclined rearward and downward to provide a camming surface for shedding the dowel tongue I! of keeper [2 and tam-event this tongue from being blocked by accidental abutment thereof against shelf 4| if the container sections and II should be out of line when forced together. ming the dowel tongue into the aperture 62 which receives it when lid H closes. downagainst or nears the body In of the trunk or other container, and'serves :to urges/aid lid and body into true planar-alignment and .hold themthere. The concave contour of the aforesaid-camming faceof tongue I I accommodates .and may wedge against keeper tongue I! prevents movement of keeper l2 toward the right, and that the interlocking engagement .of anchor tongue 58 with aperture 16 fprevents movement of the former toward the right. By this combination of means the described over-centering action is assured. At this 7 time aperture 52 in striker flange 41 of angle member "5] is in position to receive lock bolt 24 The incline of shelf 41 assists in cam-if.

Also in the side Walls 44 .of lever 43 thereis carried a pivotpin 54 which projects through the spacedlarms of the looplike haspili, being headedxover outside of the latter-as a means of retaining this pivot pin in place. v

The perimetricunarginal portion of the bridge slants forward'at 59 Tfromsaid plane .to facilitate .finger graspof the'hasp for maneuvering the anchor tonguewith respect to anchorage open ing 16.
