3 Claims.

This invention relates to hasp fasteners for securing and locking together separable parts of a closure particularly such parts when in the form of the lid and body parts of a trunk so 5 hinged together that the front walls of both the lid and the trunk body substantially align in a common plane when the lid is closed and separate in an edgewise line of movement as theV lid is opened. Some features of the invention relate particularly to means for releasably fastening the hasp while others relate to means for locking the hasp when in its releasably maintained position.

It is a well known construction to provide swingable hasps with a fastening member pivoted thereon and designed to be manually swung relative to the hasp proper for performing an overcentering or toggle-like action operating to draw together separable parts of a closure and thereafter to hold the hasp in its closed position by the fact of the hasp-carried fastening member slightly passing the point where it presses With agreatest resistance against some fastening abutment. Such constructions have heretofore required extreme accuracy of location and dimensions in the parts which co-act to effect the overcentering or toggle action above referred to because of the absence of any designed means to permit resilient yielding for accommodating such action, which means are novelly afforded and are provided in a novel manner by the present improvements.

It is an object of the present improvements to avoid the above mentioned objectionable features of hasp fasteners as heretofore constructed while providing a hasp which shall reliably 'and releasably maintain itself in closed position and in its movement to such closed position draw tightly together against the opposing force of resilient abutting means the lid and body portion of a trunk or other container. When such abutting means are made continuous along the meeting edges of the lid and of the trunk body, they also afford a weatherproof seal which is maintained by this drawing together action of the hasp fastener.

Another object is to provide a hinged hasp which to outward appearances when closed comprises but a single swingable part but which part conceals within itself when the hasp is closed both the toggle acting means for the aforesaid purposes and a lock carried by the hasp, or carried if preferred by the trunk body or by the part of any closure which is separable from the 55; closure part carrying the pivot from which the hasp is swung. Where the lock is carried by the hasp it is made accessible for operation through a wall of the hasp and where the lock is carried by the part of the closure which is overlapped by the hasp when closed, the wall of the hasp may have an aperture giving access to the lock. In the former case a striker or equivalent means for the lock to engage Vis carried by the container and in the latter case a striker may be carried by thev hasp. The invention in its broader aspects is not limited to any precise form or type of lock nor to any particular form of striker or other means with which the lock may engage.

Locks as heretofore combined with hasp fasteners incorporating a toggle acting self-fastening tongue have been located at or near the free end of the hasp thus interfering with, or reducing the space available for, giving a handle grasp formation to the free end of the hasp, or at least necessitating that the hasp be made objection ably long or wide in its portion overlying the front wall of the trunk for the purpose of providng such handle grasp. Hence a further object of these improvements is to locate a lock between the toggle acting tongue and the hinge end of the hasp, thus leaving the free end of the hasp clear of mechanism to enable it to be formed as a narrow and preferably cutaway handle for opening the hasp.

These and other objects ofthe invention will be plainly understood from the following description and appended drawings:

Fig. 7 is a View similar to Fig. 2 showing a modied form of hinge plate and catch block exposed by partially breaking away the side Wall of the hasp.

Fig. 8 is a view looking from the left at Fig. 7 with a portion of the front wall of the hasp broken away and its carried parts omitted to expose the hinge plate and catch block of Fig. 7.

Fig. 9 is a perspective view of the cantilever tongue detached.

Fig. 10 shows the contour of the hasp handle taken in section on the plane ID-IIJ in Fig. 8.

In Figs. 1 and 2, I0 represents the front 'wall of the body portion of a container or trunk and II represents the lid or closure therefor. In the particular form shown, the lid carries a weatherproofing strip I2 securely held along the edge of the lid and shaped to rst contact an inwardly turned lip I3 of the container wall at its most inward portion whereby the strip I2, being made of solid rubber or any suitable yielding material, serves as an abutment between the lid and the container limiting the extent to which they may be drawn together butupossessing a certain amount of give. There are many other forms of yielding or compressible abutment strips which may serve a similar purpose and use is made of the small amount of give which they afford in the mechanical action of the hasp fastener of these improvements.

To the wall IU of the container there is secured by concealed screws I4 a catch block I5 which, in the construction of Figs. l and 2, is shown to be integral with a downwardly extending ornamental medallion I8. To the lid II is secured by means of the concealed screw I'I the hinge block I8 which, in the form shown in Figs..

1 and 2, is integral with an upwardly extending corresponding medallion I9, not fully shown in the drawings but which near its uppery extremity may further be secured by an additional concealed screw..

Hinge block I8 carries the pivot pin 20 on which is hinged a hollow, channel-shaped hasp member of suitable contour to merge in appearance with the upper and lower medallions and to be grasped comfortably and conveniently by the hand of a user for lifting and lowering the lid and for fastening and unfastening the same. In Fig. 2 it will be noted that the uppermost position to which hasp 2| can swing is limited Vby the engagement of the wall of the hasp withV the hinge block I8 which prevents the hasp from swinging into overlying position against the lid and thus enables the hasp to be used as a projecting handle for raising and lowering the lid.

Spanning the lateral walls of the hasp member 2I, at a point near its free end, is a pivot pin 22 on which the cantilever tongue 23 is free to swing at its bifurcated end which carries a spur 24 adapted to engage a transverse partition 25 of the hasp member and to be urged into engagement therewith by the spring 26 as shown by broken lines in Fig. 2. Spring 26 is coiled about the pivot pin 22, one of its ends overlying the partition 25 and the other end bearing upon the free end of tongue 23 between its bifurcated parts.

In Fig. 2 the catch block I5 is shown to be hook shaped at its portion 21 whereby there is provided a recess or seat adapted to receive and retain the free end of the tongue 23 which is guided to such seat by any suitable cam surface 28 leading to,

and preferably continuous with, the curvature of the recess formed by the hook. From the broken line position of parts in Fig. 2, it is clear that in the closing movement of the hasp the free end of tongue 23 rst contacts the cam surface 28, after which continued movement of the hasp to its fully closed position indicated by full lines, causes the tongue to swing inwardly of the hasp as opposed only by the light tension of spring 26. At the same time, the end of tongue 23 rides upwardly on the cam surface 28 naliy seating itself against the hook portion 2'I of the catch block I 5, and the tongue 23 is made of such length and its point of seating against the hook portion 2l is so located relative to the pivot pins 28 and 22 that an overcentering or toggle action takes place as the hasp completes its closing movement. 'I'hus in Fig. 2 a straight line I'-A passing through the centers of pivots 20 and 22 is seen to traverse the hook shaped portion 2'I of the block I5, whereat the free end of tongue 23 seats, when such line moves to its position I-A in the closed position of the hasp. v

In the overcentering action just described the lid II will be drawn most closely to the container wall I0 when the line I-A exactly aligns with the point of seating of tongue 23 (see Fig. 7) and in this position of the hasp, the Weatherproofing strip I2 is distorted or compressed within its elastic limit and thereby, through its tendency to cause the lid to open, exerts a force on the hasp 2I acting through the block I5 and tongue 23 tending to draw the hasp toward the wall of the container and maintain it closed. This same force, having its origin in the tendency of the lid to separate from the container yieldingly opposes manual attempt to pull the hasp away from the wall of the container, and the hasp by means of the cantilever tongue 23, is thereby seen to be a self-fastening hasp capable of retaining itself in fully closed position when swung thereto without requiring the separate manipulation of fastening parts as ha's'commonly been practiced in the fastening of haspsl Y It is further apparent that from these improvements the advantage arises of having to provide only one moving part in connection with the hasp proper and of being able to cover and conceal that part, the tongue, as well as the container carried catch with which it cooperates entirely within the hollow of the hasp member. Thus the working parts are'protected, rendered tamper proof, and leave the hasp proper susceptible of a wide choice of decorative contours and ornamental design unimpaired by visible mechanical features.

A lock may be provided to positively prevent opening of the hasp in a variety of ways, `and the lock may be mounted in xed relation to the catch block I5 on the container and provided with a movable bolt arranged to engage a striker carried by the hasp, but in these improvements the lock Y is carried by and contained within the hollow of the hasp.

Referring to Figs. 1, 2 and 3, the catch block I5 is provided with a striker notch 29 adapted to be engaged by the bolt 30 of the lock whose casing 3| is riveted, or otherwise suitably secured, to the hasp member 2 I. The bolt 30 is most plainly shown in Fig. 3 to be so shaped, for cooperation with a detent post 32 xed in the lock frame 3l and with a C-spring 33, that a ward of the key 34 may shift the bolt upwardly and downwardly between retracted and projecting positions, respectively, in each of which positions the bolt 30 will be retained by the c-spring. The key barrel 35 opens to the exterior of the hasp for insertion and removal of the key.

A further feature of the present improvements resides in the aligning lug 36 projecting from the hinge block I8 to be received by the aligning pocket 3l formed in the top edge of the catch block I5 thereby to render more positive the designed overcentering action of the cantilever tongue 23, as well as for the more common purposes of aligning lugs and pockets well understood in the design of trunk hardw'are.

Figs. 7 and 8 show a modied form of hinge plate 38 and catch block 39 respectively secured to the lid 4D and container 4l which lid and container may be provided at their junction 43 with some compressible or yieldable element such as the weatherproong strip l2 of Figs. 1 and 2, but which lid and container in the form shown, meet solidly when they are drawn together by the cvercenteri-ng action of the cantilever tongue 23 in the closing movement of the hasp. In the construction shown, it is found in practice that there is sufcient give to the mechanical parts, themselves, to accommodate a successful hasp fastening action of the tongue 23, although it will be understood that it becomes of increasing importance in the latter case that the cantilever tongue be of the correct length, or at least not too long, else the parts would be strained in the action of closing the hasp.

Also in Figs. "I and 8 it will be noted that the aligning lug 36 and its pocket 31 are omitted, the walls of the lid and container being stili enough to provide the required rigidity which will insure the desired overcentering action of the tongue 23. Further in the modification of Figs. 'l and 8, it is seen that both the hinge plate 38 and the catch block 39. are confined to a size and so disposed that they lie entirely within the hollow of the hasp when it is closed, and the hasp closes into direct abutting engagement with the exterior surface of the lid and of the container completely closeting all of the above named parts. An abutment 42 may or may not be provided to limit the upward swing of the hasp.

Fig. 7 particularly shows the nature of the contours given to the free end of the hasp to facilitate grasping it for effecting its release from closed position, and Fig. l0 together with Fig. 6, indicate the undercut formation given to the sides of the hasp at and near its free end to assist in the same purpose.

It will be understood that any of the features shown in the hasp fastener construction of Figs.

l and 2 may interchangeably be used with any of the complementary features of the constructions shown in Figs. 7 and 8. The invention is not limited to any of the precise shapes and constructions herein illustrated and described, but consists in all equivalents thereof and substitutes therefor that are included within the fair meaning of the appended claims.
