TRUNK LOCK.

Application filed August 2, 1928, Serial No. 296,989.

This invention relates to locking mechanisms :tor trunks, suit-cases and like receptacles 111 which two sections, usually lunged on one side are to be locked to each other and sition engages with complementary locking members upon the opposite. section of the trunk, the locking bar being moved to a looking position by a hasp when the hasp is moved to a locking position.

One of the objects of the present invention is to provide an improved locking mechanism of this character in which the locking bolt or bar is mounted within the channel member which constitutes one margin of one section 0f the trunk, the locking bar thus being firmly supported and guided in its rectilinear movement without any chance of the locking bar becoming dented or deformed or other wise prevented from operation, such mounting supporting the lockingbar against pull which would draw it out of alinement with the complementary locking devices on the other section and relieving all strain upon the lock of the hasp. i

A still further object is to provide on one section oi the trunk a channel bar which fits over and is riveted to the margin of the sec tion and which contains and guides the look ing bar and provide a channel section on the margin of the opposite section of the trunk which will snugly receive the first named chaimel bar, the first named channel element being hollowto receive a locking bar but acting as a tongue when inserted in the groove of the channel on the second named section, so that bothsections of the trunk,- when the trunk is locke h will be held from any defor mation and will be held in alinement, thus doing a ay with the necessity 01 using lugs for this purpose and absolutely preventing any warping of the trunk. l t

A further object and a very important one is to provide a locking attachment which may be made up as a unit and which comprises the two channel bars with the locking bar and the h asp mounted permanently upon one of the channel bars so that these two channel bars may be readily applied to the bodies of trunks by ordinary workmen without the necessity ot peculiarly constructing the trunk initially, and another object in this connec tion to proviili means whereby ordinary in may the" w the trunk.

nbers upon the marginsof the trunk sections with certainty that they will be disposed in proper position", or in other words, to provide stops on these channel sections engageable with the edges of the trunk sections, limiting the in- WllCl movement of the channel members and thus doing away with the necessity of exact measurements and adj ustmentson the part of the workmen in placing these attachments on A further object, as before stated is to provide means whereby the locking bar may be shifted longitudinally by the rotation of the hasp and provide a rack and pinion connection between the axis 01 the hasp and the locking bar and by attaching the hasp to one of the channel members to set thepinion close to the locking bar, thus making thedevice very compact and securing a positive en gagement between the pinion and rack on the locking bar Q Another object in this connection is to so construct the pinion that the margin of the locking bar will always be received Within a recess in the face of the pinion, thus preventing any disalinement between the rack on the locking bar and the pinion and keeping the pinion always in mesh. V

Another object is to so dispose rivets through the channel member enclosing the locking bar that these rivets shall act as stops limiting the insertion of the margin of the trunk intothe channel member as heretofore stated, and also provide stops limiting'the movement of the locking bar and holding the locking bar in place; i

Another object is to provide the female channel member which receives thetongue on the opposite channel member with a plurality of transversely extending rivets which are disposed relatively close to each other and formthe locking bar with diagonally extending cam slots intersecting transversely tendingslots onthelchannelmember, these transversely extending slots in turn being adapted to receive the rivets on the female channel member, so that these rivotswill always be held in proper alinement with the slots in the male channel member andalways in position to be engaged by-the locking bar.

Another object is to so "form the inclined slots in thelocking bar so that they will act to draw the two sections of the trunk"positively together when the locking bar is shitted to a locking position and. also aetto force the tan til-ans off the trunk. "is anti locking bar is shifted toward and from its unlocked position.

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

My invention is illustrated in the accompanying drawings wherein Figure 1 is an elevation of a portion of a wardrobe trunk showing the meeting edges of the two sections of the trunk and with these two sections locked together. 7

Figure 2 is a like view to Fig. 1 showing the sections unlocked and separated.

Figure 3 is a vertical longitudinal section through two channel members showing the locking bar in its locked position.

Figure 4 is a like view to Fig. 3 showing the two members in unlocked position;

Figure 5 is a section on the line 55 of Fig. 3; I

Figure 6 is a section on the line (S6 of Fig. 4;

Figure 7 is a fragmentary vertical section through a locking bar and sheath, the section being taken through the top end of the sheath and locking bar shown in Figure 4.

In Figs. 1 and 2, 1 have illustrated fragmentary face views of a wardrobe trunk, the sections being designated A and B, respectively. It will be understood that these sections may be of any suitable character and each section is formed with a front wall des ignated a and b respectively.

As shown in Fig. 5 the front panel a of one section is enclosed within a sheath formed of a channel member designated generally 10. This channel member at its open edge is wide enough to embrace the margin of the panel a and then beyond the edge of this panel is contracted in width as at 11, so as to form a tongue as it may be termed. This tongue 11 as shown in Fig. 2 is longitudinally slitted at a plurality of points as at 12. Both ends of the channel member 10 are closed as shown in Fig. 7 at 13 by bending the material of the channel member over at the ends.

Disposed within, and snugly fitting in the hollow tongue 11 is the longitudinally extending locking bar or bolt 14 made of relatively heavy metal and being shorter than the length of the hollow tongue 11 so that it may be reciprocated therein. The locking bar 14, as illustrated in Figs. 3 and 4 is formed at intervals with upwardly and inwardly inclined slots 15 which, at their upper ends extend parallel to the edge of the locking bar as at 16. These slots, each at its lower end, widens out to form a relatively large mouth 17, and these slots are so disposed that they intersect the inwardly extending slots 12 formed in the tongue 11.

The channel member 10 is supported upon the margin a by means of a plurality of rivets 18 which are disposed adjacent the inner margin of the channel member and also extending across the channel member are a plurality of rivets 19. These bear against the edge of the panel a and also bear against the edge of the locking bar 14. This locking bar as shown in Figs. 3 and 4 is formed on its rear edge with a plurality of longitudinally elongated recesses 20 and the rivets 19 are disposed to intersect said recesses. The shoulders 21 at the ends of the recesses act as stops when they engage with the rivets 19 and thus the rivets 19 hold the locking bar firmly in place against the front edge of the tongue and also act to limit the rectilinear movement of the locking bar.

The rear edge of the locking bar is formed with rack teeth 22 and eoacting with these rack teeth is a sector-gear or pinion 23 mounted upon a square shank 24. This shank at its upper end passes through a washer 25 which fits within an aperture formed in the inner wall of the channel member 10 as shown in Fig. 6. The outer end of the shank 24 passes through a face plate 26 which is riveted, welded, or otherwise attached to the outer wall of the channel member 10 as shown in Fig. 6, this plate, as shown in Fig. 2 extending beyond the channel member and being riveted at 27 to the panel (a. Th s p ate has a depressed portion 28 for the reception of a concave-convex base plate 29 to which the hasp 30 is hinged.

This base plate rotates upon the plate 26 and as the hasp is rotated from the position shown in Fig. 1 to that shown in Fig. 2, or vice versa, the shaft 24 is rotated, thus oscillating the pinion 23 and shifting the locking bolt in one direction or the other.

The opposite margin of the panel I) is also enclosed within a channel mcn'iliicr 31, which, as shown in Fig. 5 is formed from one sheet of metal bent upon itself to provide an inwardly extending recess or socket 32. By bending the metal in this manner the socket 32 constitutes a stop limiting the inward movement of the channel member 31 upon the panel I) andthe scoket member is formed with two thicknesses of metal constituting each wall of the socket and thus making this portion particularly strong. The channel member is extended rearward of the inner wall of the socket and cn'lbrzutes the margin of the panel 6 and is held thereto by rivets 33. The margin of the panel 7) is, therefore, bound within a sheath of metal which is convoluted so as to provide a socket. the convolutions acting to strengthen the metal sheet. At intervals the socket is intersected by a plurality of transverse rivets 34- which I will hereafter term locking rivets and which are complementary to the slots 15, these slots as it will be seen, defining downwardly projecting tongues or hooks 15 adapted to engage behind these rivets 34, when the hollow tongue 11 is inserted within the channel 31 and the locking bar forced downward.

It will be noted that the joint between the two sections of the trunk along the entire front of the trunk is formed of six thicknesses of metal, and that this joint is further strengthened by the locking bar 1a which snugly fits within the hollow tongue. Thus this joint is rendered particularly strong against any possible deformation due to baggage smashing, or mishandling and held against any possible warping. It is when the trunk is closed that it is submitted to the most violent handling and at this time the joint is t'ori'ned by the six thicknesses of metal. previously referred to, and the locking bar, and these parts are further strengthened against deformation by the rivets 3a which hold the two walls of the socket or channel from any accidental spreading and assist to hold all the thicknesses of the metal together as though the locking bar were not removable. At the same time the locking bar and the tongue 31 act to hold the two walls of the channel or socket member from any collapse. Thus the trunk is rendered particularly strong at a portion of the trunk which is ordinarily very weak, that is, at the junction of its front panels.

As seen in Fig. 6, the segmental pinion 23 has disposed on each side of it the plates 35, these plates extending out to the extremitics of the teeth of the pinion and therefore (iverlapping the inner edge otthe rack teeth 21, so that the rack teeth 21 areheld in mesh with the pinion at all times and cannot possibly get out of engagement with the pinion undcr any uusal condition of use.

The hasp 30 carries upon it, of course, the usual key operated lock designated generally 86. The opposite section B of the trunk carries attached to the channel member 31 the plate 37 of common and usual construction having a recess or keeper opening 38 within which the inner end of the lock casing is received in the usual and ordinary manner. The hasp and the keeper are of any ordinary and usual construction and require no description therefore.

In looking the trunk the two sections are brougltit together until the rivets 34: are disposed within the slots 12. These rivets need not be forced home within these slots because this'tull inward movement of the rivets or keepers 34c is secured by shifting the locking bar 14: downward tfromthe position shown in, Fig 1 to that shown in Fig. 3. This dmvnward movement causes the inner inclined edges of the tongues 15 to bear against these rivets or keepers 34L and. cam them inward until they enter the straight portions 16 of the slots 15. A'i urtherdownward movement'ot' the locking'bars brings the locking bar to the position shown in Fig. 3 and fully closes the trunl'nbringing the two sections .into the position shown in Fig. 1 and the tongue 11 into its fully ineither upon the hasp or the lock. There is i no strain which can by any possibility turn the hasp or tend to turn it, and the lock 36 therefore is only necessary to hold the hasp closed. 1

Obviously, the hasp'acts as a handle having a considerable leverage whereby to opcrate thelocking bar and inasmuch as the locking bar has a wedging action as regards the action of the tongues 15" upon the pins or rivets 34c it follows that great force will be exerted at intervals along the entire length of the trunk to draw the two sections of the trunk positively together, so that no great exertion is needed to close and lock the trunk even when the trunk is very full.

When the trunk is being unlocked and the hasp is thrown from the position shown in Fig. 1 to that shown in Fig. 2, the locking bar moves upward. and the inner edge of the slot 15 acts to force the two sections of the trunk apart by hearing at a plurality of points against the transverse keeper rivets or pmsSi, thus the trunk cannot bind when it is closed and may be readily opened with the exertion of only aminimum of force.

It is intended that the channel members 10 and 31 shall be put out as articles of manu'- facture and sold to trunk makers for ap plication to the bodies of trunks; The lock structure is, of course, attached to the channel members and under these circumstances the rivets '19 for the channel section 10 play animportant part, not only in holding the channel section in proper form and preventlng any detachment of the locking bar after it has been inserted within the hollow tongue, but by acting as stops limiting the inward movement of the channel member'lO upon the panel a. j 1

Thus an unskilled workman may simply force the channel onto the panel a and when the edge of the panel abuts against the rivets 19, the workman knows that the channel is in proper position for inserting the rivets 18 without the necessity of measuring or gaging. Of course, thismargin or the trunk is cut away for the accommodation of thepinion 23, but otherwise than this and the eventual drilling of the holes for the passage of the 1711 6178 18, nothing has to be done to the edge of the channel until after the channel member has-been put in place. The channel member 31 is'inserted in the same manner over the edge of the panel 7) and in this instance the re-entrzmtsocket 32 constitutes the sto by which the workman knows when the chari nel member-has been fnlly'insertedf He can then insert and flatten the rivets 33 with surety that this channel member is correctly and truly applied.

The insertion of the tongue 11 into the channel member 31. along the whole length of the front of the trunk not only strengthens this joint, as previously stated, but makes it water and dust-proof, and the fact that the locking mechanism is attached to these channel members and that the channel members are so readily inserted over the edges of the sections a and 71, makes the device practically fool-proof for the workman assembling this portion of the trunk.

This invention not only greatly improves the appearance of the trunk but particularly prevents all. detoi'mation or warping of the margins of the front panels along the entire extent thereof and severest tests given to trunks having this lockin mechanism thereon, tests wherein the trunks were subjected to jars, strains, etc, to which they would never be subjected in use, has dcmonstrated the fact that such jars and strains will not and cannot act to prevent the easy opening or closing and locking of the trunk.

Attention is walled to the fact that the two sections of the trunk are held in engagen'lent with each other against strains whiclrwould tend to pull them apart at a very large number of points so that practically the two margins are held in such locking engagement along the entire lengthin front of the trunk instead of at one, two, or three quite widely separated points.
