BAG-FRAME LOCK.

Application filed April 5, 1923.

To all whom t may concern.'

Be it known that I, HUGO TUEGKMANTEL,

a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Bag-Frame Locks, of

which the following is a specification.

This invention applies to that class of securing means used to positively hold the oplO posed sides of a hinged frame in fixed relation when closed.

Locks of such character are commonly employed on travelling bags, valises and like containers in which a key is inserted. pressure applied and the plain unnotched ward of. the key used to move a locking member, thus releasing the frame sides, permitting them to open.

It has therefore been one of the objects of the present invention to provide a lock which eectually resists attempts to turn an ordinary key therein, thus providing safety from unauthorized intrusion. Y

Another aim is to produce a lock the casing vof which is shaped and adapted to guide the keeper in entering therein.

A further purpose is in the provision of means for guiding the key straight into its operative position, thus avoiding one of the annoyances of common looks and at the same time lessening the cost of key construction.

Still further objects are, to provide a casingV comprised essentially of a single piece of sheet metal, shaped, bent and provided with engaging elements to produce a neat appearing and rigid structure that can be economically manufactured, assembled and applied. These several objects, aims and purposes are accomplished by the novel and practical construction and arrangement of parts, further on described and shown in the accompanying drawings, constituting a material part of this disclosure, and in which Figure 1 is a perspective view of abag lock and its keeper as made in conformity v with the invention and showing its application.

Figure 2 is a rear side elevational View of the lock, parts being in section to disclose the construction.

Figure 5 is a sectional view in perspective illustrating the depressible bolt plate and its associated parts as drawn to an enlarged scale.

Figure 6 is a perspective View of the shift plate controlling the action of the lock.

Figure 7 is a similar view showing a modiied form of shift plate.

Figure 8 is another like view illustrating another variation in shift plate construction.

Figure 9 is a side view of the key used in connection with the lock, its stem being partially in section.

Figure 10 is a perspective View showing a portion of a .modified form of casing cover plate and barrel integral therewith.

The illustration in Fig. l shows fragmentary portions of a conventional bag in which the material of the bag sides is designated by the numerals l5 and 16, the same being sewn or otherwise firmly attached to coverings 1'? and 18 enveloping the rigid angular frame members 19 and 20, the latter of which exceeds the cross sectional dimensions of the former and is arranged in overlying relation therewith when the frame sides are closed upon their hinges.

Rigidly fixed to the frame side '1.9, to eX- tend horizontally outward from its upper member, are two keeper plates 2l containing openings 22 adapted to enter the-lock casing` and become engaged by the bolts therein.

This casing is composed of a front plate 23 sheared and bent to produce ends 24 and then turned oppositely outward to form feet 25 having openings 26 for the reception of rivets 27 by which they are rigidly secured to the inner surface of the vertical element of frame member 20.

In a like manner the bottom plate 28 is bent rearwardly from the lower edge of the plate 23 and provided at its ends with clip extensions 29 tightly folded over the ends 24, re-enforcing and holding the same in position. Y

The plate 23 is extended upward and slightly outward along its entire upper edge and adapted to deflect and guide the keepers 2l into the openings 3l in the casing front.

A top plate 32 extends from the back of the detlector 30, coincidentally with the bottom plate 28, level with the upper edges of the feet 25 and has at its ends clips 33 folded over the end walls 24, said walls being formed with similar clips 34 folded over the ends of the top plate, as best seen in Fig. l.

The top plate 32 is further held to the casing by rods 35 riveted therein near its ends, the opposite ends of the rods being riveted in the bottom plate 2S and pass in parallel relation through the casing.

Held by rivets 36. centrally on the top plate 32, is a flanged barrel 37, which may be rect-angular, ovoidal, or flat with rounded ends as shown, and which extends upward through an opening in the horizontal element of the frame side member 20, terminating below an escutcheon plate 38, indicated by broken lines in Fig. l.

A pair of catch bolt-s 39, having bevelled faces adapted to engage and be depressed upon contact with the keepers 2l, are arranged centrally of the openings 3l and rigidly secured at their bases to a bar composed of plates 40, 4l and 42 rigidly held together and perforated, as at 43, near their ends to slide freely on the rods 35, being held in a normally raised position by coiled compression springs 44 encircling the rods as shown in Figs. 2 and 3.

The uppermost plate has a central raised portion 45 in which is a key hole 46. The center plate 4l is straight throughout, may differ in thickness and contains a registering key hole 47, and the lower pla-te 42 is `formed with a cent-ral lowered portion 48 in which is rigidly Hxed a guide post 49, extending axially through the key holes to a point slightly above the raised portion of the upper plate.

A sleeve 50 is slidably fitted to the barrel 37 and provided with a closed upper end or escutcheon 5l in which is a key hole 52. At the lower end of the sleeve are integral parallel elements 53 passing through the raised portion of the upper plate and then turned outward to form fastening lugs 54.

Said element-s 53 are slotted, as at 55, to receive a pair ol opposed feet 56 firmly held to t-he top oi' the plate by the lugs 54 and 'formed with the feet 56 is ashell or inner sleeve 57 having a cover portion 58 containing a key hole 59 having` a downwardly Hanged edge. l

These several key holes are made to accommodate a key 60` shown in detail in Fig. 9, lits stem being drilled, as at 61, to receive the guide post 49 and provided with a ward 62 having a slot 63. Y

I't is to be noted that, due to the inner guide 58, in which the key hole is flanged downwardly, the length of the post 49 is materially less than usual, effecting an economy in its construction.

It is further noted that the width of the ward 62 is substantiallyv equivalent to the space between the upper and lower plate members 4() and 42, and Athat the position of the slot 63 conforms with the location ot the center plate 4l, the function oft' this plate being to prevent the Ywar-d from turning it' there is no slot in it or if the slot be improperly placed.

The several plates 40, 4l and 42 Vcomposing the bar are firmly secured together to act as a unit are collectively formed with a recess 64 in their front edge extending past the raised portion 45 of the upper plate and are further recessed to a similar depth as at 65 on one end. Y

A stop plate 66 having an extended base is slidably arranged in the casing, closely adjacent the front wall 23, its raised central portion entering the recess 64 and Vcontaining a slot 67 adapted to receive the ward 62 by which it is actuated.

The movement of the plate loi'igitudinally within the casing is limited and controlled Y by angular notches 68 and 69 in the plate, these notches being receptive of a detent 70 shaped to suit the notches, offset and carried on a spring arm 71 held by a rivet 72 to the bottom plate 28, this arm also acting as a guide for the plate 66, the opposite end of thearm being further secured by having one of the posts 35 pass through it.

The plate 66 is provided'at oneV end with a seat or stop 73 at a lower level than the main central portion of the plate, and at the other end, beyond the notches, is a raised stop 74, its' upper surface being in the plane of the stop 73. Y

This plate is clearly shown in detail in Fig. 6 and as assembled in Fig. 2, inwhich position the stop seat 73 aligns with the recess 64 and the corresponding stop seat 74 with. the recess 65 in which condition the plate will permit the vertically slidableVV members of the lock to be depressed, which movement obviously retracts the bolts 39 from the keepers and allows the bag frame to be opened.

When it is desired to lock the bag, the key is inserted, readily finding its proper position and upon turning the key its ward, if properly slotted to clear the plate 41, Vwill enter the slot 67 shitting the plate 66 and causing the detent 70 to spring up and over into the notch 69. Y 1

The plate 66, when Vshifted as last described, presents its stop seats 73 and 74 below the vertically movable plates avoiding the recesses and positively preventing .them from being moved down to free the bolts from their keepers.

In place of the separate flanged barrel 37 held by riveting or otherwise to the casing top plate 32, said plate may be drawn by press methods to produce an integral barrel 37 shaped as preferred and which is more attractive in appearance besidesheing expensive in asembling.

In the modification shown in Figs. 7 and 8. the plate 66 is used with certain modica tions which render the intermediate element L t1 of the vertically slidable plates unnecessary and it is therefore omitted, the construction in all other respects being in accordance with the foregoing description.

The modification consists in the device shown in Fig. 7, ot' providing one or more laterally extending lugs on the plate 66, these lugs being raised to intercept and prevent turning of the key except its ward be fitted to avoid the lugs in a manner which is clearly apparent.

In a similar manner the lateral flanges 76, as shown in Fig. 8, accomplish the same purpose and further more tend to stiffen the plate, either type of key obstruction simplifying the lock construction by reducing the number of parts.

Although I have described my improvements with considerable detail and with respect to certain particular` forms of my invention, I do not desire to be limited to such details since many changes and modifications may well be made without departing from the spirit and scope of my invention in its broadest aspect.'
