This invention relates to trunk locks and particularly to that class I of trunk-locks having a recess to receive the upper end of the hasp, and wherein the 'hasp is hinged 6 to the lower section of the trunk and carries at its upper end a lock casing adapted to be receivedin the cup or recess of the base plate and engaged therewith by lock bolts.

These looks as ordinarily constructed are weak at the point of hinge connection between the hasp and the base section which isattached to the lower section ofthe trunk, for the reason that the hasp' is not braced against lateral' oscillation or lateral move- 5 ment with relation to the base plate on the lid of the trunk and one of the objects of my invention is to provide means for bracingthe hasp against any lateral movement when the trunk is closed and when the lock is closed so that the base plate on the lid 7 of the trunkand ,the hasp act practically under thesecondi-tions, as a solid or rigid member having no relative lateral play.

A further object of my invention is to provide a lock of this character inwhich the cup receivingthe lock proper carried upon. the hasp, is formed integral with the baseplate as distinguished from being attachedfto the baseplate and, therefore relal0 tively weak. A s i i. a v this cup as to provide recesses or keepers within which the bolt or bolts are received, which akeepers will not act to unduly weaken o Another object is toso 'forin the hasp immediately surrounding the keyholepf the hasp that the combinations O fllllllk j'lOOkS may be varied :without changing the tum blers of the locks.

' Other objects will appear in the course of the following description.

My invention is illustrated panying drawings wherein i, 5 Figure 1 is, a front elevation of a, trunk lock constructed in accordance with my invention; V a

flar. ribl24, the extremities of which terini- Fig, 4 is a rear-elevation of the hasp Fig, 5 is an elevation of the lock carrying platej 7 1 1 Fig. 6 isa section through the head of the iasp. v v o Referring to these drawings it willbe seen that, the portion of the'lock which is attached to'the lid of the trunk comprises a baseplat'e10.v This ispreferably stamped, from a sheet offmetal to rovide the circular cup 11, and outward of this cup theconcentric, outwardly bulging rib 12 which extends nearly around the cup but terminates in .tWo vertically disposed hollow ribs 13 extending downward parallel'to each other, theseribs'being carried down below the lower end of the plate, as at 14. It will be noted that these portions 14 are slightly odepressed relative to the outer faces or "the portionsl iofthe rib. The cup 11 at diametricallyop osite points lSfOI'IIlQCl with slits 15 and t e' material below these slits is forcedoutward as at 16, see Figure 3, so that 'theupper walls of these slits 15 con-' stitute kee erswithfwhich the bolts of the "lock area apted to engage. 7'

The hasp consists of he base plate 17 and the tongue 18. This ton ue has a circular head .19 and is made of relatively thin metal as at2 1f, andothe central portion of thefhead being ,annularl'y depressed "as at 22, and formed with "a central opening 23 havinga 22, therefore, constitutes akey ward as will base plate 17 for thetongue 18 is" of stamped metal to provide a nearly annu nate parallel portions 25 which are adapted tooreceive the portions 14 when the lid of the trunk isclosed. The central portion of the base, plate 17i'sembossedin any desired manner to strengthen it or make it 9 more or less ornamental and eXteriorly of the hollow rib 24 the base plate 17 is formed withv apertures for the passage of \rivets wherebythe 'base plateois held to the body of thetrunk. The tongue 18 is connected to the base plate by means of a U-shaped yoke 26 and the base plate is formed with a re-bent tongue 27 to form a bead disposed between the ends of the yoke 26. The ends of the yoke 26 are formed with eyes and a pintle 28 extends through the bead formed by the re-bent tongue 2T and through these eyes. lhus the tongue 18 of the hasp is hingedly connected to the base plate of the liasp. i

Disposed against the inside "face of the head 19 is a cup-shaped lock casing 29, see Figure 5, which is riveted to the head 19 at a plurality of points, thislock casing having the laterally projectible spring pressed bolts 30 ordinarily found in trunk loeks'o'f this character, and a barrel 31 which through tumblers disposed within the casing, acts to retract the bolts 30 when the barrel is rotated by means of the key 33 inserted in the slot 32 of thebarrel. A face plate 34 is riveted to the outer face of the head 19 of the hasp, this face plate having a centraloutwardly bulging portion formed with a central opening within which the barrel 31 operates.

It will be noted, of course, that the slot 32 is adapted to align, when in one position,

with the extension 23 of the central aper- 3O ture 23. The annular depression of ward 22 coacts with the key 33 in a manner which will be later stated. o

1 it will be seen from Figure 1 that when r the hasp is in engagement with its keeper that the tongue 18 lies between the project ing rib portions 13 and the head lies within the annular ribbed portion 12 and that the extensions 14: or the ribbed portions 13 extend down beyond the hinge for the hasp so that under these circumstances any lateral 'inovement of the base late 17 and the hasp with relation to the base plate 10 is absolutely prevented or reduced to a-n extremeiy small amount so that the lateral wrenching action which tends to damage the ordinary trunk lock is not" present in my improved construction, and thus when the lock is closed, the lid and the body of the trunk are held from relative lateralmoveinent. Nhen the head 19 of the hasp is inserted within the cup 11 the bolts 30 will spring into place behind the outer walls oftheslots 15 thus locking the hasp and the plate 10 or keeper to gether. v at its will be seen from Figured the head 19 with its opening 28 is disposed inward of the I face plate 3 1 and the margins 22 of the opening 23 constitute a ward and unless the key 33 is fitted to pass this ward the key cannot be turned and thus it will be obvious that by having this portion 22 disposed at dilierent distances from the face plate 34, that wards located at different distances from the face plate 34 are provided and thus one variable element in the lock is provided which, with the variations in the disposition of the regular wards, will permit a large number of different combinations to be made. Thus on one lot of locks the rim or margin 22 will be forced inward to a certain depth and on another lot of locks this portion 22 may be forced further inward. In another set of locks this portion 22 may be forced outward or nearer to the face plate 34: and in still another set of locks this plate 34: will be disposed in the plane of the metal forming the head. Thus, by varying the distances oi this portion- 22 from the plate 34, various combinations may be made which will very greatly vary the combinations capable with locks having the same tumbler arrangement. Thus, in Figure 6 I have illustrated the portion 22 as being slightly pressed inward and the key 33 as being formed with a bit, out

away at .35. Unless this ward 22 fits this recess 35 the key will not operate within the lock thoughthe bit of the key is properly notched to tit the tumblers.

Itwill be seen that I have" provided a trunk lock which may be stamped up out/of sheet inetahwhich may be cheaply constructed and yet which is thoroughly Strong and rigid in actual use. Furthermore I have provided a lock, the combination of which is easily changed by the disposition of the ward formed by the portion 22 and that further in this improved lock the cup, which constitutes the keeper, is integral with the it is obvious that many changes might be i madeztherein without departing from the spirit of the invention as defined in'the appended claims.

In the foregoing description, and in some base plate and over- I of the appended claims, I refer to the hasp as being vertically positioned in use,'and to the flid ofthe trunk, inferring that the lock herein disclosed is used with what is known in the trade as a general service trunk.

'lhis is done, however, merely for convenience of description, and it is ofcourse to be understood that my improved lock is equally applicable to wardrobe trunks, in connection with which the lock will be horizontally disposed and the hasp and base plate carried by the respective trunk sections, instead of lower section and lid.

I claim:

1; In a trunk lock, a keeper plate having a lock receiving cup ressed out therefrom posite oints, the wall inward "of the slit and having portions 0 its side walls pressed being orced outward to thereby provide outward to provide keepers with which the keepers with which the bolts of a lock are 10 r bolt of a 100k may engage. adapted to engage. 5 2. In a trunk look, a keeper plate having a Intestimony whereof I hereunto aflix my 1001: receiving cup pressed out therefrom, signature. the side wall of the cup being slit at op- ALLEN T. LONG.
