FASTENING FOR ATTACI-IE CASES, BOXES, BAGS, AND SUCH LIKE.

Application filed .Tune 8, 1925, Serial No. 35,666, and in Great Britain July 18, 1924.

The invention relates to fastenings for vflttach cases, boxes, bags or the like comprising two primary parts, one of which comprises a slidable bolt drawn back against the action of a spring by manipulation of a slidable knob or boss carried by the face of this fastening part. The invention relates only to this fastener part. The other primary fastener part is usually a staple, eye, or a notched stud adapted to be engaged by the bolt and sometimes carried by a flyoff hasp.

According to the invention said knob or boss is provided with a looking or blocking device in the form of a revoluble piece which, when moved to one position prevents the drawing back of the knob or boss (and therefore the bolt), and, when moved to another position, permits said knob and bolt to be freely drawn back. The blocking piece pleferably forms apart of the knob or boss so as to partake of the sliding movement of the knob or boss but may be partly revolved on the knob orboss, independently of movement of the latter, in order to effect the blocking and releasing action. The bolt is positioned between the front plate and the back plate of the fastening part and is connected through the front plate to the knob or boss, an opening being cut through the front plate for this purpose. The blocking piece partly revolves about the knob or boss and has a stop which is movable in the opening of the front plate in either one of two positions, one permitting the bolt to be drawn back, and the other preventing the movement of the bolt. The blocking piece may be a thin fiat ring working between the underside of the knob and the face of the front plate and having oppositely disposed, forwardly extending projections to lie over the boundary of the knob and form finger grips.

lVhen the blocking piece is in position to prevent the withdrawal of the bolt a part of it may lie over the hasp of the other fastener part to visually indicate that the bolt is blocked against movement.

Several embodiments of the invention are shown in the accompanying drawings.

A fastening part, such as that to which the invention relates, frequently has a key locking mechanism forming part of it, and this is indicated in the drawings by the keyhole and key post only, the key-hole in all of the illustrated embodiments of the invention, except one, being formed in the knob or boss, and in that one through the front plate adjacent to the knob or boss.

here permissible, similar letters of reference are used to indicate the same parts in all the figures of the drawings.

Referring to Figs. 1 to 10, a indicates one primary fastening part, and c the other primary fastening part. The part c is secured to the lid .(Z of the attache case or the like, and :the part a to the body e of the attach case or the like, in the usual way. The part 0 comprises an attachn'ient plate 0' to which is hinged at 0 a hasp, 0*, carrying a staple for engagement by the bolt.

The fastening part a comprises front plate piece a between which the bolt f is mounted to slide. The bolt has a nose end which slides across the slot at of the front plate to engage the staple of the hasp c of the part c. The spring for automatically shooting the bolt 7 is indicated at 9. An opening it is formed in the front plate. The slidable knob or boss i is mounted on the face of the front plate to cover the opening it, and is rigidly connected through said opening to the bolt f by projections 2' which extend through holes F, f of the bolt and are clinched down at the back of the bolt as represented by Fig. 2. A key-hole j is formed in this knob or boss, which is hollow, to co-operate with a key post is on the bolt 7. The aforesaid is all normal practice in such a fastening part.

The invention provides the knob or boss 'i with a locking or blocking device Z in the form of a thin fiat ring disposed between the underside of the knob 11 and the face of the front plate a This ring device is separately rcvoluble about the knob or boss but partakes of the knobs sliding movement with the bolt Projections Z Z of the ring device Z extend forwardly of the latter and lie over the boundary of the knob to cnstitut-e finger grips, while a stop Z of said ringlike device works in the opening it of the front plate. The revoluble piece Z is adapted to have a quarter of a revolution about the knob i, to bring its stop Z either into the position shown in Figs. 1 and 2 or into a position to abut against the back edge if of the opening 7i. When the stop Z is in the position within the opening it shown by Figs. 1 and 2 the bolt 7 can be drawn back by a straight-line sliding movement of the knob or boss, carrying the blocking device Z with it. If the blocking device lis revolved a quarter-turn to bring the stop 1* against the abutment edge if of the opening it the drawing back of the bolt 7 by the knob is blocked or prevented, giving efficient security, without key-locking, against the bolt being accidentally withdrawn.

The revoluble ring Z is limited to a quarterrevolnt-ion engagement of a projection on its inner periphery against the two projections i of the knob or boss.

it is to be understood that the fastening rt need not be formed with a key locking mechanism, but preferably it has such.

Fig. 11 shows a fastening part similar to that shown in Figs. 1 to except that the linger grip Z of the ring-like blocking device Z is of extended length and is adapted, when the blocking device Zis in bolt-blocking position, to lie over the fly-off hasp 0* to visually indicate that the blocking device is in locked position, the device Z, when in this position, being quite close to the face of the hasp.

Figs. 1.2 and 13 show a fastening part ema and back plate bodying the invention wherein the key hole is not cutthrough the knob or boss i but through the front plate a to one side of said knob or boss.

Figs. let to 16 show a modified embodiment of the invention wherein the revoluble blocking device Z is external of the knob or boss i, so that apparently the knob or boss itself partly revolves, which however is not the case, said knob or boss 2' being covered by the locking device and rigidly connected to the slidable bolt 7' by the projections and Having now described my invention, what I claim and desire to secure by Letters Patent is 1. A fastening device comprising a casing having a front plate provided with a catch receiving slot, a bolt slidable in said casing" and having a catch engaging nose, said front plate also having an opening adjacent said catch receiving slot, a knob slidable on the outer face of .said front plate and having a part extending through said opening and fixedly secured to said bolt, and means mounted on said front plate in advance of said opening and rotatable relatively to said knob, said means adapted, when partly rotated in one direction, to engage a wall of said open ing and prevent movement of said knob.
