HASP FASTENING FOR SUIT AND ATTACHE CASES AND THE LIKE Filed May 6, 1932 W Z W5 5 w Patented Aug. 1, 1933 nAsr FASTENING FOR SUIT AND ATTACHE CASES AND THE LIKE.

Charles William Cheney, Birmingham, England Application May 6, 1932, Serial No. 609,574,

r g and in Great Britain July 6, 1931 53 Claims. (Cl. sea-235.)

The invention relates, to the hasp member of hasp iastenings whose other member is usually a lock member, and distinctly to a hasp member comprising two main pieces, the one an attachment plate, and the other a hasp bar slidably hinged at its one end upon the attachment plate so as to be adjusted therealong, and so as to be swung to open and closed positions, ratchet engagements being provided between the attachment plate and the haspbar. A hasp spring is provided between the attachment plate and the hasp bar to normally swing the latter.

outwardly todisengage the ratchet action.

-Such a hasp member is described and illustrated in the specifications of my prior British Letters Patents Nos. 323, i27 and 361,567.

According to the invention a pivoted pawl is provided at the hinged end of the hasp .bar and a separate spring to operate onsaid pawl for the ratchet action. The pawl is disposedwithin the. trough section of the haspupon a crossly directed pivoting pin, while the pawl spring is also disposed within said trough section and is held therein by engaging under the pivoting pin. The hasp bar spring is a torsional one loosely mounted upon the pivoting pin and having limbs to contact the hasp bar and the attachment plate for normally swinging the hasp bar out-- wardly. The pawl spring is only a light powered one and therefore sensitive, and enables the pawl to have a very soft andsilent ratchet action with the ratchet teeth. The hasp bar spring is one of much greater power being operative to normallyswing the hasp bar outwardly. 'The pawl and both springs form part of the hasp bar; so that the latter only needs to be assembled as one piece to the attachment plate formed with the ratchet teeth.

The invention is represented in two desirable forms by the accompanying sheet of drawing, Figs. 1 to 4; representing one form, and Figs. 5 to 8 the other form.

Fig. 1 is a vertical side section.

Fig. 2 is a front elevation of Fig. 1.

Fig. 3 is a back elevation of the hasp bar and its component parts separately.

Fig. 4 is a section of Fig. 2-011 the dotted lines AB.

Fig. 5 is a vertical side section.

Fig. 6 is a front elevation of Fig. 5.

Fig. 7 is a back view of the hasp bar and its component parts separately.

Fig. 8 is a section of Fig. 6 on the dotted lines CD.

With reference to Figs. 1 to 4, the rigidly'built attachment plate a, adapted for fixing to the exterior front of the lid-of a suit or like case in the depthwise direction of said lid, has standing up rigidly and centrally from its face, for-its full length, a rigid rib c of substantially rectangular cross-section. The longitudinal edges of the rib are turned inwardly to provide rightangled flanges c2, 03 as in my prior Patent No. 323,427.' A central line of ratchet teeth (I is provided upon the face of said rib.

A rigidly built hasp bar e, forming at its lower end a carrier for a staple, c2, is mounted at its upper end upon the rib c to slide there along and hinge thereon, said upper end being formed with hook. edges, c3, c4, to engage the flanges c2, c3, aforesaid. on the rib in such manner that this upper end can slide on the riband, at the same time limitedly hinge thereon. The hasp bar is of trough cross section corresponding to the cross sectional shaping of the rib c, and its engagement with the rib holds it against lateral displacement, This upper end of the hasp bar is permanently connected to the rib without the use of any hinging pin, and whenthe hasp is closed the whole of it lying over said rib is held I laterally by the sides of the trough cross section lying closely against the sides of the rib.

All the foregoing is in accordance with my prior British Letters Patent No. 323,427 except the line of ratchet teeth d on the face of the rib.

According to the invention the hinged end of the swingable hasp bar 6 is provided with a pivoted pawl, or catch, f and with two springs g and h, the former being a pawl spring and the latter a hasp bar spring. The pawl is pivoted upon a crossly directed pivoting pin 2'. Said pawl and springs are snugly disposed within the. trough cross section of the hasp bar and inwards of the rocking engagement of the hook edges e3, 64 with the flanges of the rib, the pawl being between said hook edges. The pawl spring g engaged under the pivoting pin 1' and crosses the tail end of the, pawl, it being alight wire spring of substantially hairpin shape. The hasp bar 100 spring h is a torsional one having two pairs of limbs 7L2, I13, joined by coils 7L4, the latter loosely surrounding the pivoting pin 2' and the limbs arranged for operation one pair against the interior of the front wall of the hasp bar, and the 5 other pair against the face of the rib c. The spring It operates to normally swing the hasp siderable strength, but the spring g is of very there is similarly, as in soft and silent spring ratchet action of the pawl into action.

It will be clearfrom description aforesaid. of the drawing that the hasp bar carrice the pawl, the pivoting pin and the two springs as a one-piecepart thereof, and that the simple assembly of the hasp bar to the rib, by sliding said bar onto rib from the lower end, brings the parts described into proper rfela tionsl ip for operation.

With reference to Figs. 5 to 8, the hasp bar 6, the pawl i, the pivotin g and It subste lly in accordance with what has been des ibed with reference to Figs. 1 to 1, but the attachment plate part is substan tially in accordance with the similar part described and represented in the specifications of my prior Letters Patent No. 61,567, that is of say, the attachment plate is provided with a straight hasp-rec iv .g groove c2, the base of which is formed a parallel and central line of; ratchet teeth vvhile the bottom edges of said grooves are formed with opposite 1ongitudi- LLB.

nal slots a4, while in'suoz-stitution for the hooks 63, a l of Figs, 1 to at, opposite integral ears of; are provided upon the upper end of the hasp Inemb r 6 to be introduced into the opposite side slots a4 and bent at-i'igl'rt angles, for hingedly and slidably connecting the upper end of the hasp bar to the attachment plate, this latter being also in accordance with my prior British Patent No. 361,567, and clearly shown by Fig. 8. In this form the invention, Figs. 5 to 8, l to l, the sensitive in relation to the ratchet teeth d.

Having now described my invention," what I claim and desre to secure by Letters Patent isl. A two-p1 ce hasp'member combining an attachment plate formedupon its face with a rigid rib whose edges are turned inwardly into flanges in i and the two springs and which rib is provided with a central line of ratchet teeth upon its face, a rigidly built hasp of trough cross section mounted at its one end upon the rib to slide therealong and hinge thereon and which has hook edges to engage the flanges of the rib, a hasp spring to normally swing the hasp outwardly into oblique position, a pawl mounted upon the hinged end of the hasp by a pivoting pin and adapted to engage the line of ratchet teeth of the rib, and a pawl springcarried by the hasp andadapted to operate upon the pawl, substantially as described.

2. A,two-piece hasp member combining an attachment plate formed upon its face with a straight hasp-receiving groove the bottom of whichis provided with a central line of ratchet teeth and the sides with longitudinal slots, 21. rigidly built hasp of trough cross section mounted at its one end within the groove to slide therealong and hinge therein and which has ears to engage the slots of the groove, a hasp spring to normally swing the hasp outwardly into an oblique position, a pawl mounted upon the hinged end of the hasp by a pivoting pin and adapted to engage the line of ratchet teeth of the groove, and a pawl spring carried by the hasp and adapted to operate upon the pawl, substantially as described.

3. A two-piece hasp member comprising an attachment plate, a central line of ratchet teeth formed upon the face of said plate, a rigidly built haspdirectly mounted at its one end upon the attachment plate to bodily slide therealong and to bodily hinge thereon at said end, a hasp spring to normally swing the entire hasp outwardly to oblique position from its hinged end, a pivoted pawl directly and immediately applied to the hinged end of the hasp to be always a part ofsaid hasp and adapted to and disengage the line of ratchet teeth of the attachment plate and a pawl spring also carried by the hasp and adapted to operate upon the pawl only.
