Claims. .(Cl. 29222 8) This invention relates to fastening devices and more particularly to a fastening device for suitcases and other receptacles which comprises a spring pressed hasp and an associated catch so arranged as to hold the receptacle in a closed condition.

The primary object of this invention is to provide a fastening device for suitcases, bags and other types of hand receptacles, as well as trunks and other stationary receptacles having closeable lids or tops, which may be economically manufactured and assembled and which will give an efficient and long life of service.

A further object of the invention is to provide a fastening device of the type described having a spring pressed hasp pivotally mounted on a supporting shell in such a manner that if the spring should break the hasp will remain in position.

Another object is to provide a fastener construction for a suit-case in which the hasp is automatically aligned with the catch when the parts are closed together and the parts will not be disengaged as a result of lifting the suit-case by its handle.

A further object is to provide a fastener of the type described in which the operating parts are so shaped and arranged that the outer surface of the-device is substantially streamlined and presents a pleasing appearance and wherein the parts are so constructed that the hasp is laterally supported in a required position by the shell carrying the same.

Referring to the drawing illustrating the preferred embodiments of this invention:

Fig. 1 is a perspective view of the two parts of the fastening device in positions just prior to locking engagement thereof;

Fig. 2 is a central sectional view of the parts in a locked arrangement;

I Fig. 3 is a perspective view of the under sides of the parts shown in Fig. 1 but with the spring removed;

Fig. 4 is a perspective view of the spring;

Fig. 5 is a perspective view of the under side of the pivoted hasp;

Fig. 6 is a view corresponding with Fig. 2 but employing rivets instead of bendable prongs for securing the same to a receptacle; and

Fig. '7 is a perspective view of the under sides of the shell and catch with the parts shown in an open hasp position.

The suit-case fastener shown in the drawing comprises a shell or base it carrying a spring pressed hasp l2 shaped to interlock with a lug I4 on a catch l5. The hasp has two aligned pivots I6 shaped to be mounted in twoaligned bearing slotsll formed on an appropriate part of the shell. The pivots are so positioned that the hasp is a lever of the first degree and has a short arm or cam 18 adapted to engage a spring 20 fixedly mounted in the shell. The cam and the spring are so located and positioned that the hasp is held in either a locking or an open position. The shell may be provided with prongs 22 and 23 (Figs.-1 to3) which are arranged to be forced through the leather or other body material of the suitcase on which the part is to be fastened and then bent over into position to hold the shell in place. Similarly the catch may be provided with prongs 24 shaped and arranged for the purpose.

One feature of this construction involves so arranging the hasp and the catch that when the parts are brought together, they are automatically positioned and the hasp is located correctly for looking with the catch lug. To this end, the shell is provided with a tongue 25 projecting beyond the vertical front side 26 of the shell and into a position where closing of the suit-case cover will thrust that tongue through an opening 21 in the side peripheral wall 28 of the catch. The wall 28 is a continuation of the front wall 29 of the locking lug I l, so that the tongue 25 is located beneath that lug. V The catch is preferably formed of a piece of stamped metal as a cup shaped or hollow member having the continuous peripheral rim 28 forming a strengthening flange, and the prongs 24 ma'y be shaped as a part of that rim; The rear wall 32 of the lug M is shaped as a partial cylindrical surface adapted to interfit with the front curved wal1'34 of the hasp. The hasp wall is made just enough larger than the locking lug I4 so that the parts fit together snugly. The catch also has a rearwardly projecting lug 36 which engages the surface of the suit-case and aids in steadying the catch under th forces involved in closing the suit-case and carrying the same. The catch member may, however, be otherwise suitably shaped as deemed advisable.

- The hasp is similarly made of pressed sheet metal as a cup shaped body having the top and substantially plane portion 40 and the two side ribs orflanges 4i formed as continuations of the curved flange 34 which engages the locking lug. A thumb hold 42 may be provided as a forwardly projecting plate shaped and arranged to aid the user in raising the hasp readily from its locked position. The back wall of the hasp is extended and shaped to provide the curved cam lip l8.

the shell even if the spring 20 should break., Also, it is supported against lateral movementso as to provide a. strong structure. To this end, the shell I is formed as a substantially cup shaped member having its peripheral flange com-. posed of the sides 50 integral with the front flange or wall 28 and a rear flange -I- formed as a continuation thereof. The shell is made of a sheet metal blank pressed to the desired shape and it has an outer surface provided with a suitable metal plating. The prongs 22 are continuations of the rear wall of the shell and the partsare made of metalcapable of being .bent and shaped-as desired.

-The sides of the hasp are confined against lateral movement by two substantially parallel, vertical ribs 54 formed by cutting through the shell andbending the shell material into positions which are perpendicular to the surface o f the suit-case on which the shell is fastened. That is, these ribs 54 are substantiallyparallel with the side flanges 4| 5 of the hasp and define the sides of the central opening through the shell. Likewise, the prong 23 is formed from stock bent up from that central portion of the shell. The peripheral flange portions 26, and 5| and the ribs 54 have their bottom edges lying in a common plane so that each will engage the surface of the suit-case on which theshell is mountedand thus give a full 'and common support for the shell. The ribs 54 are cutaway to form the two semi-circular grooves'oi' slots i1 which thus serve as bearings for the pivots IS. The ribs 4! of the hasp will thus lie close to the ribs 54 when in a locked position and the .pivots'lii will be supported only on these ribs I Thefhasp is held in either ofits end positions by the spring 20, and this springis preferably made U-shaped asshown in Fig. 4 with a proiecting lip so which lies within th iho ilowpf the projecting tongue 25- of the base plate. The

tongue'is bulged outwardly for the purpose of both strengthening'the tongue and of providing the required space for the end of thespring. The lip is held in position by the flanged walls of; the tongue 25 so that the spring will not move at that point. The springrests on a portion 63 of the uncut part of the shell, and it is of such a size that it lies snugly between the. ribs 54 with its U-shaped portion against the prong 2 3 hencethe support 63, the prong 23, the ribs 54 and the walls of the tongue 25 hold the spring in-its proper position. After the spring has been dropped into place, the lugs 62 projecting as a continuation of the flange 2 6 of.the shell are bent down over the adjacent portions-of the spring and thus serve to hold the spring tightly in position. The cam or lip l8 of the locking hasp is of such size and arrangement that the there are no bearings visible from the outside. The outer faces of the shell and the closed hasp lie in almost the same plane or are streamlined to produce a pleasing effect. This results from having the hasps sunk into the shell when in a closed position as is provided by the space between the ribs 54.

It will now be appreciated that the various parts may be suitably modified as required by one skilled in the art, within the knowledge imparted by the above disclosure. For example, as shown in Figs. 6 and 7, the shell and the catch may be secured to the suit-case by means ;of rivets 10- inserted through countersunk openings H and 12 punched in the shell and catch tops.

In this construction, a further lug 14 (Fig. 7) is cut out andbent up to a position at right angles to the plate 63 forming the adjacent portion,of the shell and the top edge of this lug l4 lies in the same plane with the two side lugs 54 and the flange walls of the shell. Theedges of these -various parts contact with the surface wraised above the under edges of the shell and serves on one side to supportthe spring 20 and on the other side to engage the side flanges 4| oithe hasp in a closed position. c 7

a It will now be appreciated that the parts may be readily assembled by first dropping the hasp into positionjhrough the central opening of the shell which is just wider than the hasp. The aligned pivot posts lii will fall into position in the semi-circular bottoms of the slots I1 fOIIIl'. ing their bearings. The spring 20 it putinto place and the prongs 62 are bent over to secure the spring in its. location. The parts are so mounted on the two movable portions of the suit-case'or other suitable receptacle that the prong 25 of the shell 10 will fit into the slotted opening 21' of the'catch and beneath the locking lug i4 and thus cause the portions 32 and 34 of thehasp and lug to be brought into locking engagement Qnce the hasp I2 and spring have been put into position and the shell I0 mounted on a suitcase, the hasp cannot be thereafter removed -even if the spring 20 should' break. Neither the hasp-northe spring can be moved laterally because of theretaining sidewalls 54 engagingtheir sides. Lateral movement of the two' parts of the" suit-case is prevented by this double locking feature comprising both the prong 25 and the hasp i2 engaging the under andupper parts of the locking lu'g' .14. It is to be noted that the shell. I0 and the associated haspare ordinarily located on the part of the suit case which. carries the handle, hence anyupward springwill hold the hasp securely in either a.

locked or a wide open position. Any intermediate position of the locking hasp causes the cam l8 to bend the spring downwardly and thus impart a reactant force against movement of the hasp, The pivots l6 of the hasp and all of the operating-parts are hidden inside of the shell and pull of the handle cannot "cause disengagement of the parts since the tongue 25 merely holds more tightly against the under side ofthe catch lug .14. Also, any lateral twisting of the case because of an.uneven balance while being carried is taken up by the walls 54, the tongue 25 and the associated parts and cannotfree the hasp from the catch. The pivots ii are supported solely .by the slotted bearings I! of the vertical walls 54, and this:obviates the necessity rorpres'sing the shell to provide special bearing shapesto carrythose-pivotsi That is; theshell is smooth surfaced over the pivots and presents a pleasing effect. Many other advantages will be apparent in this construction to one who is skilled in the art.

It will also be appreciated that numerous modifications in this structure may be made and that the drawing and the above description are to be interpreted as illustrating the general principles of this invention and the preferred embodiments thereof and not as limitations on the invention except as are defined by the claims appended hereto.
