LOCK.

Specification of Letters Patent.

Patented Sept. '7, 1920.

Application filed November 5, 1917. Serial No. 200,337.

To all whom it may concern:

Be it known that 1, JOHN I. SrnnN, a citizen or the United States, residing at VJaukegan, in the county of Lake and State of Illinois, have invented certain new and useful improvements in Locks, of which the following is a specification.

This invention relates to improvements in locks of the keyless type and one object is to provide a lock of this class adapted particularly for use on trunks, suit-cases, traveling bags and the like although the lock is,

capable, as well, of a very general use. A further object is to provide a lock of this type that is neat in appearance, simple in construction since it is composed of few parts, and that is cheap to manufacture, and that will not become locked in open position.

With the foregoing andv other objects in view the invention consists in the construction and novel combination and arrangement or parts hereinafter fully described, illustrated in the accompanying drawing which forms a part of this specification, and pointed out in the claims hereto ap pended, it being understood that various changes in form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the'drawing:

Figure 1 is'a face view of my improved lock.

Fig. 2 is an edge view of the same in open position and partly in section to afford a better illustration. 7

Fig. 3'is asectioual fragmentary plan view of the interior of the lock, taken on line 3 3 of Fig. 2, but with one washer omitted to disclose the top tumbler more clearly.

Fig. iis a View similar to Fig. 3, the aforesaid washer being included, but with the movable parts in an altered position.

Fig. 5 is a sectional view of theindicator. Fig. 6 is a section on line 6--6 of Fig. 8. Like reference characters denote corresponding parts throughout the several views.

The reference numeral 1 denotes'an anchor plate designed to be securedby the screws 2 to the body portionB of the trunk or other article to be locked. To the plate 1 a leaf 1 is secured by hinge 5, the free end of said leaf being formed with a flat rounded portion 6 whereon the numbered graduations 7 are formed and in which the spaced apertures 8 are formed. I formed about the flat portion to afford protection iior an indicator 10 which is adapted for registration with the graduations 7 and which extends through an enlarged opening 11 formed centrally or" said fiat portion 6 to permit liberal relative movement of said indicator. The indicator 10 is a hollow me1nb'er,'circular in cross section and closed at one end and formed of two concentric detachable cup-shaped portions, one of said portions being formed with the flange 13 and the ether with the terminal flange 12 from which the lug 14:

is bent, said flanges being positioned upon opposite sides of the flat portion 6.

A plate 15 provided with lateral wings 16 is secured to the trunk top thereby, said plate being formed with a circular central depression 17 and with an outer rounded edge 18. An inverted U-shaped yoke 19 has its ends secured in the bottom of the depres sion and its base spaced above the said depression, said yoke extending through an aperture 20 in the bottom of a casing 21 which casing is circular in shape and adapted to fit inside the depression 17, said yoke 19 permitting limited play of said casing but preventing rotation of the same within said depression. The casing 21 is provided with a sight perforation 21 and is formed along its upturned rim with the spaced lugs 22 adapted for insertion in the apertures 8 oi the rounded portion 6 of the leaf 4 wherebv said casing and leaf are releasably secured together. An anchor lug 23 secured to the rim of the casing diametrically opposite the yoke 19 extends inwardly toward said yoke. A. circular tumbler casing 2% is formed with the diametrically opposed openings 25, 2G in its wall, an exte1ision27 of said casing 2 1 registering with the opening 26, said extension being adapted for insertion in the yo re 19. The base of the tumbler casing is formed with the notch 28 in the plane 01? the wall-opening 25, said notch 28 being smaller than the said wall opening. lVithiu the tumbler casing I provide a tumbler 29, adapted to rest upon the casing base, which is formed with a peripheral notch 3i) adapted to, be moved into alinement with the notch 28 of the tumbler casing and said tumbler 29 is also formed with a lug 31. A washer 32 adapted to lie directly upon the A peripheral rib 9 is ion llO

tuinloler 29 encircling the lug 31 is formed with the spaced outwardly projecting prongs 33 which project through the casing opening 25 to engage the anchor lug 23. A second tumbler 34 adapted to he directly upon the washer 32 is formed with a peripheral directly upon the tumbler 3a. is formed with the spaced outwardly projecting proiigs'33 which project through the casing opening 25 to engage the anchorlug'23. When the peripheral notches of the tumblers 29, 34mgister with the casing opening 25 the anchor lug 23 may project'into said alined notches and between the prongs of the washers to prevent independent rotary movement of one or more of said elements and due to this fact it is practically impossible for the relative position of the tumblers to become disturbed while the lock is open. The tumbler casing iscapable of a sliding movement'ovcr the casing 21 and when-the notched portions of the tumblers and of the tumbler easing are engage(jl by the anchor lug 23 the tumbler casing has moved into such position that its extension, 27 is re moved from the yoke 19. When the tumbler casing is moved out of engagement with the anchor lug the extension 27is again disposed within the yoke 19. The flange 12 fits snugly inside the periphery of the tumbler casing 24: and movement of the indicator 10 in the elongated slot 11 is sufficient to cause the said flange 12 to slide the casing 24 back and forth upon the bottom of the casing 21 to cause engagement with or disengagement fromthelug 23.

l/V hen the notched portions of the tumblers and thecasing opening 25 are in alinement, the indicator 10' maybe moved to move the tumbler casing back'and forth over the casing 21, described, since theterminal flange 12 of said indicator fits snugly inside the rim of the tumbler casing. The lug 1% of the indicator projects toward the tumbler 34 inside the washer for engagement with the lug 36, which projects from each lateral face of said'tumble'r, as the indicator is rotated. To determine a combination the indicator is rotated and when its lug'14l engages the lug 36 oftumbler 34 it will rotate that tumbler and the opposite end of lug 3G upoirthe opposite side of the tumbler coming in engagement with the lug 31 of the tumbler 29 will rotate tumbler 29. When the notch'BOof tumbler 29 is in 'alinement with-the tumbler-opening 25, as may be determined by observation through the sight perforation 21?, a reading of the indicator upon thegraduations is taken. The indicator is now rotated in the opposite direction"thus rotating the tumbler 341 until its 'The direction left, or vice yersa, together with the read ings taken, form the combination. When the notches 30, and opening 25 are in alineinent the tumbler casing 24 wi l slide away from the yoke 19 through gravity when the lock is in the position shown in Figs. land 2, and this movement will also be'shared by the indicator 10, and the tumblers will move into engagement with the anchor lug 23. The gravity movement just described will take place provided the lock is retained by the trunk, to which it is secured; in vertical position which is usual. lhe' lock is'now open and in this position the tumblersfare retained in their relative positions by the anchor lug so that the mechanism cannot become locked in open position. W hen the lock is oven the casin 2'1 and leaf are readily moved out of engageinent'with the yoke 19. To lock the ldck the leaf andcasing 21 are again moved into engagement with the yoke 19 and the indicater moved toward said yoke and then rotated when the notched portions of the turnblers will be disposed out of alinement with each other and with the opening 25 in the tumbler casing.

lVhat is'claimed is e 1. In a look, a hinged leaf formed with graduations and with an elongated perforation, a perforate casing carried by said leaf, one of the perforations in said casing being a sight' perforation, i 'a wingetl' plate formed with a depression to receive "said casing, an inverted U-shaped yoke carried by said plate for disposal in one perforation in said casing, an anchor lug formed in-said casing diametrically opposite the yoke-receiving perforation, a notched tumbler casing disposed in the first named casing, the

beingfadapted for releasable engagement 7 with said fanchor lug, said tumblerras'ing being slidable relative to said' first named casing, in one position of the latteifl'through gravity to cause disengagement of saidtumbler-casing-extension "from said U shap ed v yoke and engagement of the notched' portions of'the'tumblers with said anchor lug, a pronged washer arranged upon each tumbler within said tumbler casing, the prongs of said washers being spaced "apart for, en-

gagement with the sai danchor lug, 'lugs formed uponsaid tumblers for engagement with each other, an indicator disposed in the elongated portion of said hinged leaf and formed of two cup-shaped portions each provided with a flange which flanges are disposed upon opposite sides of said hinged leaf, one of said flanges fitting snugly inside theperiphery of said tumbler easing whereby sliding movement of said tumbler casing may be manually effected, and a lug formed in said last named indicator flange for engagement with one of the lugs of one of said tumblers.

2. In a lock, a hinged leaf formed with graduations and with an elongated perforation, a perforate casing carried by said leaf, one of the perforations in said casing being a sight perforation, a winged plate formed with, a depression to receive said casing, a yoke carried by said plate for disposal in one perforation in said casing, an anchor lug formed in said casing, a tumbler casing disposed in the first named casing in engagement with the said anchor lug, an extension formed upon said tumbler casing for releasable engagement with the said yoke, rotary tumblers within said tumbler casing capable of releasable engagement with said anchor lug, said tumbler casing being slidable with relation to the first named casing, in one direction through gravity when the lock is opened, to cause disengagement of said tumbler-casing-extension from said U-shaped yoke and engagement of said tumblers with said anchor lug, pronged washers aranged upon said .7

tumblers, the prongs of said washers engaging said anchor lug, means wherebyrotary movement of one tumbler is transmitted to the other tumbler, an indicator disposed in the elongated perforation in said hinged leaf and engaging said tumbler casing whereby sliding movement of the same may be manually effected, and a lug carried by said indicator for operative engagement with one of said tumblers.

. In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two subscribing witnesses.
