BAG-LOCK.

Specification ofLetters Patent.

Application led December 18, 1920. Serial No. 431,545.

To all fw 7mm it may 4conce/mi Beit known that we, Biionin J. RICHARD- soN and Chenin S. BARBER, citizens of the United States, and residents, respectively, of lfifaterbury, in the county'of New Haven and State of Connecticut, have invented certain new and useful improvements in Bag- Locks, which improvements are fullyl set forth in the following specification.

This invention relates to improvenientsin devices of that class available conjunctively with a suitable duplex hasp for locking together the customary hinged frame-sections of a hand-bag or the like, such devices being well designated duplex hand-bag locks.

The object of this invention is to provide a lock of the character above indicated, L

which shall be simple and comparatively inexpensive as regards its construction; durable, eiicient and reliable in practical service;

which shall embody certain novel features.`

whereby is facilitated the operation of assembling the variousk parts thereof; and which shall possess certain well-defined advantages over prior analogous constructions.

The invention consists in `certain.combinations, details and parts to be hereinafter more fully referred to and set forth in the claims hereto appended, and whereby theV attainment of the foregoing object is rendered practicable.

The invention is clearly'illustrated in the accompanying drawing, wherein:

Figure l is a top plan view of a lock embodying our` said improvements, "the depressible finger-piece being shown partly in horizontal section and the top plate of the housing being partly broken away.

Fig. 2 is a rear elevation thereof, awportion of the rear wall of the linger-piece being brolren away.

Fig. 3 is a. horizontal section of saine, the section being taken as along the dotted line 3? of Fig. 2.

Fig. e is a central, vertical, transverse sec* tion of the device, as along the dotted line 4 4 of Fig. 2.

Fig. 5 is an end elevation of the lock, the near wall of the housing being broken away.

Fig. 6 is a, detail sectional view showing more particularly the application of a key to our Vimproved loclr.

Fig. 7 is a top plan view of a fragment of the lockingbolt made use of.

Fig. 8 is a view showing-in perspective and detached the bolt-follower made use of,

Fig. 9 is a view similar to Fig. 8, showingv Patented Nov. 15, 1921.`

the bolt-locking tumbler which we purpose making use of.

Having reference denote like parts throughout the several to the accompanying. drawing. wherein similar .reference-numerals views,.we provide, in carrying out our presn ent invention, a general housing formed from metal in suitable sheet-form, and which consists, by preference, of ka base-plate 5, topplate 5', front wall 5" and opposite endwalls 6, 6.

The base-plate 5 is merged at its rear edge into .an upstanding retaining-lip o, the finction of which will be explained herein a ter.

7 denotes a locking-bolt, freely pierced bv opposite, upstanding guidespindles 7', 75 and movable upwardly and downwardly relatively thereto, said locking-bolt` afford ing opposite, upstanding catches 8, 8 engageable, respectively, with the opposite tenons, as 9, 9', of a hasp, as 8". y

The catches 8, 8 may be conveniently struck iupwardlyy from the material of the locking-bolt 7, and in such a manner that each thereof shallhave an edge-face-duly curved upwardly and rearwardly, all asA vclearly indicated in. the drawing.

By preference the loclring-bolt practice between, and cooperatively with, the front wall 5 and the dependent flange of the hinged, hand-bag frame-section to which our improved lock may be applied, service-` ably obviate all tendency'on the part of the 7 is merged` at its opposite'ends into opposite, .upstanding` guide- terminals 10,10` which guidetermimals, by reason of the same operating in es f terial of their supporting thrust-plate l0, l

or otherwise formed, as found `expedient in practice; and said thrust-plate detachedly overlying in practice the base of the housing aforenamed, between the front ,wall 5 and retaining-lip 6 thereof.

rI he locking-bolt 7 is further provided with a central aperturelOm, the purpose of which will become apparent hereinafter.

11 denotes a yoke whose medial segment is transversely crimped to `form a central, downturned, angular stop 11', said stop approximating in form the letter V and flanked Y and theopposite end-portions of said *yoke being depressed relatively tothe medial segment thereof for the formation of opposite feet l1 12,'said feet being freely pierced upwardly by `the guide-spindles 7 7 and normally bearing downwardly onV the thrust-V Yplate 10.

13,13 denote spiral springs interposed endwise between the locking bolt 7 and the feet of the yoke -11, respectively, said springs encircling, in this instance, the

lguide-spindles 7 7 f ,-respeetively, and respectively exerting at all times an elastic stress, upwardly on said, loclringfbolt, to :hold the 'same atal-l times yieldingly protracted, and downwardly on the yolie aforenamed, through the medium of the feet of the latter thereunder.

We further provide a bolt-locking tumbler whereby the locking-bolt aforenamed may be locked against retraction, the same comprisi ing, bypreference, a relatively thin, upright, Yflat body 13, adapted to lie and operate against the inner face of the wall 5 havinflfA a rearwardl turned flange 1d VVat itslower edge, which underlies'the thi-ustplate 10, and having opposite shoulders let,

14,'whosefunction will be explained later hereinafter. p Y

Since the flange 14 underlies the base 10,

it will be 'apparent that the tumbler(now,V under consideration is held yieldingly to .a

sliding engagement'with the base-plate 5 thereunder,y through the ,medium' of the springs V13, 13 bearing downwardly thereon, asindirectly by way of the feet 11, 12

and the thrust plate 10thereunder, the latiter in turn overlying and vengagiirg the 'i same, laterally in one direction for locking y flange 14. Y Y c The wall 5 isprovided with an opening 15,1by way of which access to the tumbler aforenamed may be had for shifting the the locking-bolt against retraction, and laterally in the opposite direction for freeing the same for retraction; and in this'con nection, we provide a yoke-actuating pin 15 which pierces the body 13 by way of a suitable aperture 16, is iittedatrits outer en l, eXteri'orly of the wall 5, with a finger-button 16, and whose free inner endLportion normally projects into and occupies one of the pockets, say 12', flanking the stop 11',A

Y and whereby, the pinrbeing duly urged stress of the springs 13, 13', thus permitting y finger-pressure in either direction against said stop, the. yoke 11 is lifted against the said pin to snap by and beyond the fstop 11 and enter and occupy the opposite pocket, say 12,. oppositely flanking said stop, the tumbler n' medium of its shoulders le v14 being ac ""cordingly, thrown into andr out of lockingV engagement with the loclringdoolt, and, in: vdirectly so, in this instance, through vthe aforenamed, l through v the.

medium of a novel bolt-follower, which vbears detachably downward on Vsaid locle ing-bolt, and which will nowV be described. 'As here shown the bolt-follower Vabove alluded to comprises a medial top-member 17, 'which is merged at its rear edge into a downturned rear wall-section 17', and which rear wall-section isiiiiiturn, merged at its lower edge into a 'horizontal inturned flap .17, lying beneath 'and in parallelism with the top-member 17. i'

It will be noted that the member 17 is pioy,

videdwith an :irregular key-opening 18 while the flap 17 is provided, at a point in vertical registry with the opening 18, -witli a circular aperture 18, the latter serving for thereception of lthe end-lng or tipv a suitable llrey 18. Y

vTo facilitate the detachedrmountiiig of said bolt-follower medially on and relatively to the locking-bolt of our improved lock, and as is contemplated, the downturned end-members of said follower are' merged Vat their lower extremities into op? osite, depressed feet 19, 19 freely pierced y the 'guideespindles 7', 7, thus rendering the follower movable rela! tively thereto in unison with the lockingbolt thereunder; and when thesepaits are thus Vassembled-,the aperture 18 stands in registry with the bolt-aperture 10?, thejlatter beinglin practice,A occupied to a greater or less extent by the tip of the hey A18 in comnionzwith the Vaperture 18 thei'eabove, as indicated in Fig. 6L

y reason of the fact that the apertures 18710 stand in registry, each with the other, our improved lock becomes nonpitn able j since, under these conditions, the loclring-bolt may not be retracted by means', say, cfa falselrey, strip ofi/notai, or the like inserted endwise into and more or less down-V wardly thii'iugh the aperture 18.

Pi'otraction of the locking-bolt under the stress of the springs 13, 13', .is limited by the engagement, under normal'conditions of the parts, of the top member of the bolt-follower 2 with the top-plate ofthe housing thereabove.

19 denotes a hollow finger-piece which rises fixedly from the bolt-follower re named and projects unwai-dly through endg the housing as in permit which, the is duly Vcut awaliy,

tive action the :reduced boss lor ynoch 22 of a' respectively,

` gether with the retaining Y through the crown of the finger-piece,

ylua 25 will engage and take key-way finder 22', the latter being held with suitable freedom of action against downward displacement from its position of servire by means of a retaining sleeve 22, inserted upwardly into and snugly at the opposite side-walls of, the finger-picco 19; and for more permanently securing said sleeve in place, the wall thereof conjointly with the side-wall of the finger-piece in contact therewith, may be suitably indented, as by means of a prick-punch, and as indicated at 23, Fig. e of the drawing.

lt is obvious that the finger-piece tosleeve therein should be cut away, as at 23, to provide proper clearance for the tumbler-body 13 under depressive action of the finger-piece and to permit Such action on the part of the fingenpiece.

ln practice the key-way finder isV manipie lated, say, by inserting` the tip of a suitable key, as 18, into the key-slot 24: of said finder, and then duly turning the key to bring said key-slot into registry with the clearance-notch 24', which constitutes in effect a contracted, radial extension of the major opening 2l, whereupon is formed a key-way extending in part downwardly through the key-way finder and in part and by way of which the key 18 may be inserted downwardly through the interior of the the sleeve 22, to and downwardly through the irregular key-aperture i8, and from thence downwardly to and into rotative engagement with the flap 17, on the top-surface of which bears and rides the shoulder 2li of the key aforenamed, the tip thereof now occupying` the aperture 1S, and more or less the aperture 10"', whereby the key is serviceably steadied in its turning actionn Upon the key beingnow `ogiven a partial turn, as on its own longitudinal axis, and in the proper direction, its depressed lateral with it the aforenamed, thereby laterally and to such l 5 1. lik/I bolt-locking tumbler shifting),` such tumbler an extent as to bring the shoulders thereof under the forward margins, respectively, of the feet of the bolt-follower afore named, or laterally in the opposite direction to bring; such shoulders .out from beneath such feet-margins, to lor-k said bolt-follower against depression, and hence the lockingbolt retraction in opposition to the stress of the springs 13, "lS, or to free said follower for depression in unison with said locking-bolt, as under finger-pressureV applied downwardly to the linger-piece 19, thereby causing` the catches 8, 8 to engage or disengage the tenons 9, 9', of the hasp 8, whereby the hingedframe sections of hand-bag, or the like, to one of which our improved lock may be attached as in common practice, the hasp beinpr applied to the opposite frame-section, may be locked together or unlocked, each from the other, all according to the direction in which the key 18 shall be turned; and under such shiftingof the tumbler, the pin 15 automatically snaps by the stop il', from one pocket flanking' such stop at one side thereof. to and into render the turning of the key still further involved, it will be understood that a plurality of such lugs, uniformly or variantly spaced vertically apart, may be provided, the key being provided with a like number of clearance-notches, each similar to 26', for cooperation, respectively, with such lugs.

'lo facilitate the shifting of the tumbler as above explained, the body of such tunibler is provided with a suitable upright opening or recess 26, into which enters the lateral lug' of the key when the same is duly turned. Further, opening 26 preferably fianked at its opposite sides by like openings which, in cooperation with the lateral lug of the key aforenanied, serve to such a readjustment of the tuinber as shall cause the pin l5 to ride into and occupy one or the other of the pockets flanking the stop lil, should such pin at any time become casually centered on the apex of the stop,l

To insure a more serviceable conjunction of the pin l5 with the tumbler made use of, the same is fitted with a collet 2"?, at the .inner face of the body of the tun'ibler, p1id with a dislrbushing 27 at the outer race thereof, said bushing;l working in the open ing` l5, the pin aforena-nied beingy lit-ted with the ingenbutton i6 outwardly beyond said bushing, and through the medium of` which finger-button the tumbler may be actuated by finger-pressure independently of any kej; when desired and when the frame-sections of the hand-bag; or 'the like to which the lock may be applied9 are unlocked, will be readily understood.

ln the operation of aeseinbline,l the loci mechanism. availedL of within the housing provided therefor, springs i3, i3 are contracted under finger-pressure applied oppo-` sitely to the thrustplate l0 and, say, the follower thereabove;r whereby the free ends of the guide-spindles 7 7 are caused to proing` then projected freely upward through the top-plate 5 of the housing by way of.

the openings provided therefor in such toppermit plate and with the finger-piece 19. lying within the cut-away portion 2O of said topplate. Whereupon the assembled lock-mech-` anism, with its springs aforenamed still under contraction as stated, is carried fcrwardly into the housing and into its upright position therein. Thereupon the thrust- Y late is Jermitted to snai, under the P l l stress of the controlling-springs aforenained, into its position of service within the housing, and wherein it dctachedly over-lies as stated the base 5 and is barred against casual displacement rearwardly with respect to such housing by means of the retaining-lip 6" afforded thereby. To remove the mechanism from the housing it is only needful to lift the thrust-plate l0, against the tendency of the springsl aforenamed and sufficiently to clear the top of the retaining-lip 6, free withdrawal of the mechanism rear- Vwardly from the housing being thereby perfollower detachedly bearing thereon and de-v pressiblein unison therewith; and a: lingerpiece, theV latter rising ixredly from rsaid follower and depressible therewith.
