Komenak, Stamford, Conn., assignor to The Excelsior Hardware Company, Stamford, Conn, a corporation of Connecticut Application December 11, 1940, Serial No. 369,583

12 Claims.

This invention relates to a type of lock equipped hasp fastener having a loop-like draw bolt especially suited for drawing and locking together separable edges of the hinged together sections of luggage cases, trunks, or the like.

My former U. S. patent, No. 1,652,676, discloses this general type of lockable hasp fastener in a form wherein the hasp is hung from a manually operated toggle lever but wherein a key operated lock is. provided, parts of which lock must be housed at the rear of a mounting or escutcheon plate requiring the latter to be dished or hollow and therefore undesirably thick for certain uses.

An object of the present improvements is to reduce the undesirable overall thickness of the escutcheon plate by placing the lock entirely in front of the latter and still swing the hasp from a finger operated toggle action lever as in my said patent.

A further object is to provide a lock for the hasp that is located as and for the purpose described while remaining stationary with the escutcheon plate instead of being carried on, or bodily movable with, either the hasp itself or the toggle lever from which it is swung.

A further object is to do away with unsightly apertures in the front face of the escutcheon plate for accommodating hasp keeper projections, lock bolts or the like so placed that they are objectionably visible when the hasp is open.

A further object is to do away with exposed projections heretofore carried by the hasp or carried by the toggle action lever from which it is swung for engagement and retention by the bolt of the lock mechanism.

Still further objects relate to space saving cooperative arrangements of parts which have been devised to make the above results possible. All such objects will appear in greater particular from the following description of a preferred em bodiment of the invention, in which description reference is made to the accompanying drawings, wherein:

Fig. 1 is a front elevation of a lockable hasp fastener incorporating the present improvements.

Fig. 2 is an edgewise View looking from the left at Fig. 1 showing a plurality of positions of the hasp and of the finger operated toggle action lever.

Fig. 3 is a perspective view of the mounting plate looking toward the rear outer face thereof.

Fig. 4 is a perspective view of the pivotally connected lock case, toggle lever, and hasp removed from assemblage with the mounting plate of Fig. 3.

Fig. 5 is a view taken in section on the plane 55 in Fig. 1 looking in the direction of the arrows.

Fig. 6 is a view similar to Fig. 1 showing certain of the parts in section on the planes 6-6 in Fig. 5 looking in the direction of the arrows.

Fig. 7 is a fragmentary view of a portion of Fig. 5 showing the toggle action lever in the first stage of its hasp releasing movement.

Fig. 8 is a view similar to Fig. '7 showing the toggle lever moved to its position for fully releasing the hasp. I

The mounting or escutcheon plate l0 as best shown in Fig. 3 has elongated slots II, it which receive fastening tongues l2 projecting from the side walls I3, l3, respectively, of the lock case which case as a whole is designated by M. This case is further provided with a top wall I5, the rear edge of which contains a shallow notch 60 which registers with a shallow pocket I! embossed rearward in the top of mounting plate It. When the fastening tongues l2 are swaged over at the rear of plate 10, the side walls it, top wall l5 and front wall I8 of lock case [4 form cooperatively with the front surface of plate l0 an open bottomed enclosure for the working parts of the lock mechanism. These parts may include the key barrel l9 which is rotatable in bearing holes in both the front wall l8 and mounting plate I!) and may in other respectsbe like the lock mechanism disclosed in my copencling application, Serial No. 349,339, filed August 1, 1940, inclusive of the vertically slidable plate 253 which serves as the bolt of the lock.

A pivot pin 25 is fixedly lodged at its ends in the side walls l3 of the lock case and extends therebetween and passes through the edge flanges 26 of a finger operated toggle action lever 27. The edge flanges 26 are thus pivotally supported by and freely swingable on the pin 25 and'these flanges may be formed by drawing out the metal of the toggle lever into a cup form which also produces integrally with flanges 25 the nose flange or keeper flange 28 flanking the before described bottom open end of lock case M and whose free end presents a detentive edge or corner. Flange 28 contains the keeper aperture 29 at whose rear edge the remaining marginal strip of flange 28 is deformed into a V-shape which provides the projection-3E! cooperative .as shown in Fig. 8 with a forward projecting stop lip 31 formed by bending out the metal of plate Ill. The illustrated V-shaped deformation of this marginal strip of flange 28 has been found to strengthen this flange considerably in the region of aperture 23 against yielding to forcible attempt to swing toggle lever 21 away from its position in Fig. 5 to its position in Fig. 8 when locked by bolt 29. This is because the leverage or turning moment of the opposite edges of aperture 29 with respect to lock bolt 2'4 is increased by displacing tongue 33 from the general plane of flange 23. The junctions of flanges 26 with flange 28 comprise crackless corners which render member 21 particularly strong.

Edge flanges 26 of toggle lever 21 contain horizontally aligned bearing holes in which the hinge pin 32 is turnable. The ends of pin 32 project outside of flanges 26 and thereat are fixed to the ends 33 respectively of hasp loop 34 having spaced sidearms 38 and whose curved nose 35' is adapted to engage with keeper 43.

Keeper 40 is here shown to be constructed in the form of a hollow piece of drawn sheet metal forming a saddle-like seat 4| which is convex as viewed in Fig. 1 and concave as viewed in Fig. 2. A mounting flange 42 borders about this seat and contains holes 43 to receive screws (not shown) by which the keeper 43 may be secured fixedly on, say, the lid of a trunk or baggage case. 4

When such lid is closed the flange 42 will fall in planar alignment with mounting plate ID if the latter is secured to the body of such trunk or baggage case by means of screws (not shown) accommodated by holes 2| When flange 42 and plate I!) are so related, a dowel tab 44, which is bent over and projects downward from the rear edge of the bottom wall of hollow keeper 40, is firmly lodged in the dowel socket defined jointly by the aforesaid notch |6 and pocket H in look case l4 and mounting plate In, respectively. In this closed position of the fastener parts it will be observed that all heads of holding screws occupying holes 2| or 43 are blocked off by the hasp 34 and toggle lever 21 so that no one of these screws could be removed for gaining access to whatever piece of baggage my improved fastener may serve to lock closed.

For biasing the can swing about pivot pins 25, a leaf spring member 50 is made fast to the rear or outer surface of mounting plate I!) by rivets 5 I. These extreme limits of swing are determined in one direction by the abutting of the rear edges of flanges 26 of toggle lever 21 against mounting plate It! and in the other direction are determined by abutting engagement of stops 30 and 3| as hereinbefore described. Spring member 50 slants forwardly through an aperture 52 in mounting plate I and yieldably occupies the are of swinging travel of the rear edge of the keeper flange 28 or corner of toggle lever 21 about pivot 25. Therefore this spring 50 will resiliently press upon and be rubbingly engaged by toggle lever 21 as the latter passes through its position shown in Fig. '7', which position is intermediate its positions shown in Figs. and 8. Thus spring 50 acts normally to bias toggle lever 2'! toward either its position shown in Fig. 5 or its position shown in Fig. 8.

Fig. 2 shows that the front flat faces of keeper 40, lock case l4, and finger operated toggle lever 21 fall mutually flush when the hasp is closed and locked. By inserting and turning the usual key (not shown) in look barrel ii), the locking bolt is shot upward and out of aperture 29 in the flange 28 oftoggle lever 21 whereupon the thumb or finger of the users hand can be used to swing this toggle lever from its full line position to its in the mounting plate. 1

finger operated toggle lever 21 into either of the extreme positions to which it broken line position in Fig. 2. This operation, without individually touching hasp 34, will lift the curved hasp nose 35 clear of the seat 4| from its full line position to its broken line position 34a in Fig. 2. The hasp may then be swung forward into a further broken line position 34b, whereupon it is removed from position to engage with keeper 4D and the lid of the trunk or baggage case is free to be opened. When such lid is next swung closed, dowel tab 44 enters and nests snuggly in the pocket ll, I8. I-Iasp 34 is then swung into position 34a in Fig. 2 and toggle lever 21 is then optimum tightness of closure.

pressed downward, swinging about its pivot from broken to full line position in Fig. 2. This draws the hasp nose forciblydownward against keeper seat 4| and draws the trunk lid to an Now the aforesaid lock key may be turned and bolt 20 thereby shot into engagement with toggle lever aperture 29 thus preventing further displacement of the toggle lever, and therefore of the hasp, from their full line positions in Fig. 2.

In the foregoing description of operation it may be noticed that the toggle lever 21 in swinging from its position in Fig. 5 to its position in Fig. 7 occasions very little, if any, flexure of the detentive spring and hence lifting of the finger piece end 39 of the toggle lever requires little more force than is required to overcome the frictional resistance torubbing offiange 28 against spring 50. However, in Fig. 5, spring 50 will be observed to press on the detent edge of this flange in a direction relative to pivot pin 25 which exerts considerably more biasing force opposing counterclockwise swinging of toggle lever 2'! than is the case in Fig. 7. In the latter figure an exact or near dead center relationship obtains.

For convenience, the term closure sections is used in certain of the appended claims to include the lid and body of a trunk or equivalent parts of an article of baggage, although it will be understood that my improved fastener may serve to secure together meeting parts of any form of container or closure. Modifications in the details of the particular construction of several parts of the fastener which are herein disclosed for illustrative purposes only may be made within the scope of the present invention and the following claims will be understood to comprehend and cover all substitutes and equivalents which fairlycome within their terms.
