Patented May 1, 1945 LOCKABLE HAsP FASTENER Albert Komenak, Stamford, Conn., assignor to The Excelsior Hardware Company, Stamford, Conn., a corporation of Connecticut Application February 24, 1941, Serial No. 380,294l

Y12 claims.

This invention relates to hasp fasteners of the type which incorporate a hasp in thel form of a rigid bail or draw loop pivotally hung on a toggle lever which in turn is pivotally mounted to be swung manually over a dead centering position for drawing and holding firmly together thelseparable edges of hinged together container parts such as the body and lid of an article of luggage, tool box, trunk or the like. j

A lockable hasp fastener ofv this general type is disclosed in my earlier Patent No. 1,652,676. The present improvements aim to make certain parts of this earlier fastener stronger, more conveniently operable and more compactly organized through the provision of new and more advantageous features of construction.

One object of the invention is to impart more strength and rigidity to the end of the'manually operated toggle lever which coacts with the usual .leaf spring that serves to bias the toggle lever toward its limit positions in both directions of its swing.,

A further object is to limit the swinging fall of the loop-like hasp toa forward or outward extending position when the fastener isopen, instead of permitting such hasp to drop fully to a vertically depending Vposition in close proximity to the front face of the container lbody as heretofore. This avoids having to reach to the rear of the hasp for rst retrievingit from `its down hanging position before it can .be swung to a usable position for fastening, and hence increases the readiness with whichthe `hasp can be manipulated by the users lingers and flipped into engagement with the keeper shoulder preparatory to closing and locking the fastener.

A further object is,"withinthe limited space available, to strengthen and render more rugged the lever carried striker engaged by the bolt of the lock and also to mount suchstriker more rigidly n the toggle lever.

` A furtherobject is to'sec'ure the'lock case in place by means of the same fastening tongues and by means of the same assembly operation which attaches the key barrel supporting frame jacket to the mounting or escutcheon plate.

A still further object is to produce the keeper and its carried dowel tonguefrom a single sheet of metal drawn to dished formations which provide a draw shoulder to be engaged by the hasp loop and also providethe dowel tongue.

A still further object is to secure the before mentioned biasing spring on the escutcheon plate Without the use of rivets, screws, or otherv eX- traneous fastening parts thereby to alford more room in the shallow interior of the lock case for the lock mechanism.

Theforegoing and other objects of thepresent improvements will appear in greater detail from the following description having reference to the accompanying drawing, wherein:

In Fig. 8, the sidewalls 3| of jacket` i structure 33 will be' observed to be nearer together than the side walls 65 of lock case 22 whereby the combined width of the jacket' structure and the width of the hasp arms 55 which ank it need not exceed the overall width of the lock case.

. Inside of frame jacket 3U a retainer plate- 34 assists in. supporting and retaining the key barrel,`

having for thisv purpose a bent metal formation most clearly shown in Fig. 8. The top Wall 40 of jacket 38 has a rearward turned tongue 4 ineiim,

ed somewhat downward for coacting with the dowel tongue i1 of keeper l2 to cam the latter in- .to its receiving aperture 42 when lid closes down against the body IU of the trunk or other container. This serves to urge the front walls of said lid and body into true planar alignment and hold them thus even before the fastener is closed and locked.

Coming new to the s 'wingable parts of the fas-` non with the side walls a4 andthe top wan 45; vThese top and side walls are integral and form a craokless junction at the upper end portion o f toggle'lever 43 which is pivotally supported on the mounting frame 20 by hinge pin 32 passing freely Spring |9 diverges from plate 24 and` extends past the opposite side 0i ef the?` through said side Walls 44 of the lever and lodged in the side walls 3| of frame jacket 33.

A leaf springv 49 is secured against the front face of escutcheon'plate 20 by striking `from the metal 5 of the latter a bump or boss `5|! raised toward the front sufficiently to project through and t a fastening hole in spring 49. This boss is then swa-ged over at 50 in the manner of a hollow rivet against the front face of the spring., Spring 49 coacts With the pivotally mounted end of toggle lever 43 as best shown in Figs. 3 and 4, wherefore it is clear that this spring-yieldingly opposes shifting of lever 43 away from either of its positions shown in Fig. 3 or Fig. 4 becausethe arc of travel of the edge of the top Wall 45 of toggle lever 43 necessitates rearward exingdisplaernent ,of spring. 49against the latters resilient Ytendency tov bias lever 43V into either one or the other of its positions in Fig. 3 or Fig. l as it swings within its range of positions be; low its horizontal position shown by broken lines invFig. 3. n

Lever 43 `carries welded or otherwise rmly secured to it a striker confined to the rear side of the aforesaid front lever wall in the lform of an inte- 25 gral angle piece or bracket 5l including a striker flange. 41 or perforate tongue section adapted to enter and project through an aperture 39 in the f plate wall of mounting frame 20 and which Contains an aperture 52 one edge of which provides c the strike ysurface 46 adapted i0 lee engaged and retained by the lock bolt 24 when the latter isshot downward out ef ease 2.2. byturninekey 26. Angle piece 5| further includes the mounting flange 48 which has substantiel area 0f surface .Contact with 35 the front wall of toggle lever 43 to which it is thus Well adapted to be welded or otherwise secured l ried a pivot pin 54 which projects also through 45 the hinge flanges 51 on the spaced arms 55 of the loop-like hasp56, being headed over outside of the latter as a means of retaining this pivot pin in place. Hasp -56 may be formed from nat metal bent over to form said hinge'flanges 51 and is pro- ,511 vided at its looped opposite end, or nose, with the inward projecting short tongue 58 which is retentively received into aperture I6 ln the keeper I2. The hasp arms 55 straddle the hasp operating member or lever 43.

- Heretofore when a hasp of the nature of 56 has been pivotally swung from ya toggle lever of the naturel of 43, such hasp has been able to fall fullv downward into. a vertically depending position 56 as indicated by broken lines in Fig. 4. But by these improvements the hasp can not drop to this position which would be objectionable because requiring so much greater degree of'manual swinging of the hasn in order to restore it to its broken line position 56" in Fig. 3 preparatoryl to seating it upon the keeper l2. This objective is accomplished by striking laterally outward from the metal of the Side walls 44 of the togglelever two embossed stop projectionsfabutments o r protuberances 59 Awhich engage With the arms 55 of the hasp, respectively, and thus limit downward swing of the latter relativeto toggle leverl 43 to that relationship of these vtwo parts shown in Fig. 4. Therein the hasp is angularly displaced -upward fromoperating lever 43 and ,outstands from the front face of mounting: plate 20 and from the asv-res? vertical Wall of the container on which the same is mounted.

' In the use of my improved fastener, the toggle lever 43 and hasp 56 will normally be found stably biased by spring 49 into their idle or non-working full line positions in Fig. 4 when the fastener is open. In fasteners not embodying certainv of the present improvements the hasp would be found in the aforesaid fully fallen or vertically depending position 56 indicated for purposes of illustration only by broken lines in Fig. 4. This undesirable normal or fallen position of the open hasp can not obtain in the improved construction here shown because bumps 59 serve as stop means to limit the falling swing of the hasp relative to lever 43 and hence relative to the' fastener frame plate 20 and container body l0.

To prepare the hasp for closure of the fastener it is rst merely flipped backward counterclockwise into its broken line position in Fig. 3 accompanied if desired by lifting swing of toggle 1ever43 higher than its range of working-or hasp fastening positions, after which clockwise swinging of toggle lever 43 from its broken line position to its full line position in this gure will pull the hasp downward and its nose tongue 58 into retained occupancy of aperture I in the top seating wall of hollow keeper I 2. In Fig. 3 it is seen that in completing the clockwise swinging of lever 43 hasp pivot 54 becomes slightly overcentered in relation to a projected straight line passing through lever pivot 32 and the point of bearing of the hasp nose on the seating surface of the keepery which action assisted by the bias of spring 49 against lever 43,

tends to keep these parts in their line positionA turning of the key the toggle lever will again be freed and liftable to its full line position in Fig. 4 or broken line position in Fig. 3, This lifts hasp tongue 53 clear of keeper aperture I6 whereupon the hasp can be swung forward and clear of the keeper thus restoring theI parts to their normal unfastened positions.
