To all whom 'it may concern:

Be it known that we, THOMAS NEEL, WILLIAM E. WILLIAMS, and FREDERICK il?.

OwEsNEY, citizens of the United States ol America, residing at Irondale, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to locks, and the objects of our invention are iirst, to provide a lock that can he used in connection with trunks, valises, doors and similarI structures, or as a padlock; second, to provide a lock that cannot be surreptitiously opened; third, to provide a double lock requiring separate key movements to lock and unlock the same; and fourth, to provide a durable lock that cannot be easily manipulated unless a person is familiar with the same.

The above objects are attained by a lock structure that will now be described, reference being had 'first to the drawings, wherein,

Figure 1 is a front elevation of our lock, Fig. 2 is a similar view with the key hole plate removed, Fig. 3 is a similar view with the ward plate and the key hole plate removed, Fig. 4 is an end view of the primary latch, Fig. 5 is an end view of the secondary latch, Fig. 6 is a iront elevation of the lock with the key hole plate, ward plate and primary latch removed, Fig. 7 is a front elevation of the lock partly broken away and partly in section, illustrating the secondary latch in a shifted position, Fig. 8 is a similar view illustrating the primary latch in a shifted position, Fig. 9 is a plan of a single lock' plate, Fig. 1() is a cross sectional view taken on the line of Fig. 1, Fig. 11 is an end view of a double lock, and Fig. 12 is an elevation of a key partly broken away andv partly in section.

In the accompanying drawings 1 designates a plate having a right angular eXtension 2 provided with slots 3 and screw openings 4, this extension serving functionally as an escutcheon plate when our lock is mounted in a door. The plate 1 is provided with apertured lugs 5, and with screw posts 6 and two sets of guide lugs 7 and 8 Slidably mounted upon the guide lugs 8 is a secondary latch 9 having two end slots 10 ior the guide lugs 8. The upper edge of the secondary latch is cut away to provide two longitudinally alining hooks 11, the distance 1oetween the points oi said hooks con responding to the distance between the slots 3 of the extension 2. The lower edge oi the latch 9 is cut away to provide bearing surfaces 12, 13, 14 and 1.5, adapted to be engaged by a key in moving the latch. To hold the latch 9 in engagement with the plate l and normally in a fixed position, a coil spring 1.6 is inclosed, this spring being mounted upon a pin 17, carried by the plate l. One end of the spring hears against a pin 18 carried by the plate 1, while the opposite end is bent and provided with notches 19 for engaging a triangular shaped lug 20, carried 1oy the secondary latch 9.

Slidably mounted upon the plate 1 below the secondary latch 9 is a primary latch 21 having a central opening 22 to provide clearance for a key. The latch 21 rests upon the lugs 7 and upon the plate 1 and extends upwardly and rests against the secondary latch 9, and the upper edge of the 'primary latch 21 is cut away to provide two longitudinally alining hooks 23, similar to the hooks 11. One end of the primary latch is provided with a depending lug 24 adapted to be engaged by the notched end 25 of a coil spring 26 arranged upon a pin 27, carried by the plate l. rihe opposite end of said spring bearing against a pin 28 carried by said plate. The primary latch is provided with a bearing 29 resting against the secondary latch. The primary latch at the lower edge of the opening 22 is cut away, to provide bearing surfaces 3G, 31, 32 and 33.

Mounted upon the screw posts 6 and hold ing thereon by nuts 34 is a ward plate 35 having a central horizontal double key opening 36. Circumferentially arranged relative to said openings are segment shaped wards 37 and 38 upon the front side of the plate, while upon the rear side are arranged similar wards 39 and 40. rlhe plate 35 is provided with screw posts 41 for a key hole plate 42 held in position by nuts 43. This key hole plate is provided with a vertical keyhole 44, the upper ends of which aline with the central portion of the key opening 36, and a pin -secondary latch and moves said latch to the `short distance, whereby the hooks thereof 45, carried by the plate 1. Arranged upon 1 the -late l adjacent t0 Said pi@ are tir@ war s 46 and 47.

Used in connection with the lock is a key 48 having a lon itudinal bore 49 and a radially disposed it 50 provided with slots 51 and 52.

rlhe reference numeral 53 designates an eseuteheon plate having depending loop shaped keepers 54, as shown in the drawings. My lock is employed for locking the plate 53 to the extension 2. This is accomplished in the following manner, the key 1 48 is inserted in the key hole 44 and in the key opening 36, with the bit 50 in a horizontal position at the right side of the pin 45, as shown in dotted lines on Fig. 7 of the drawings, by turning the key to the left or in the direction of the arrow (Fig. 7) the bit 450-impinges the bearing surfaces 12 of the left, whereby the hooks 11 thereof will be moved into the depending keepers 54. A further movement of the bit 50 in the direction of the arrow causes the piece to impinge the lower edge of the opening 22 of the primary latch and said key can be moved no further in this direction. rhe bit 50 is then moved to a horizontal position, the key pulling outwardly to place the bit 50 between the ward plate 35 and the keyhole plate 42, at which time the bit '50 is rswung from the left hand side vof the pin to the right hand side thereof, and again pushed in between the ward plate 35 and the plate 1. Ao'ai'n swing the bit 50 in the direction of the arrow, said piece impinges the bearing surfaces 14 and moves the secondary latch its iinal step, to a locked position,

To place the 'primary latch in a locked position, the bit 50 is swung downwardly to the left to engage the bearing surface 30 of the primary latch and move said latch a will extend into the keepers '54. New if the key was further rotated, the bit 50 would strike the bearing surface 13 of the secondary latch and partially unlock the same, so in order to continue the operation of locking the lock, particularly the primary latch, the bit 50 is vmoved between the plates 35 4and 42, the piece swung to the right side ofthe pin 45 and then swung downwardly to the left to engage the bearing surfaces 32, and move the primary latch its final step. To unlock the latches 9 and 21, the operation is reversed, and to prevent the lock from being picked, the wards 37 to 40 inclusive are provided, these wards being cleared by the slots 51 and 52 of the bit 50, the slot 51 receiving the wards 37, 38, 46 and 47, while the slot 52 receives the wards 39 and 40.

It will be observed that to manipulate our lock, requires an in and `out movement ofthe key besides reverse movements within the 1 reot'ion. serve functionally as tumblers, we render the l,lock burglar proof, due to the fact that'the f latches can be moved in unison.

latch in a fixed lock for moving the latches .in a desired di- -ln providing two latcheajwhich lf the key is not properly manipulated in the lock,`one

. latch will be shifted to a locked position while the other latch is shifted to an unlocked position, and since it requires four movements of the key to completely unlock the latches, it i" with considerable difliculty that a person provided with a key opens the lock, unless familiar with the manner of manipulating the key. It would be a comparatively easy operation il.' the latches `could be observed,

but when the lock is ineased in a trunk, or door, it is impossible to determine when the lock is open, except by trying the trunk lid or the door. u

ln llig. 11 of the drawings we have illus- 'ti-ated a double iock that can be used in connection with a door, one of the locks constitilting an outside loch and the other an inside lock.

the lock can be incased in a suitable inetallie casing (not shown) and secured to a door without embedding the saine therein, a suitable provision being made for supporting the plate 53 and the keepers 54.

While in the drawings forming a part of this application there is illustrated the pre- 4 ferred embodiments of our invention, we would have it understood that the elements therein Vcan be varied or changed, as to the shape, proportion and manner of assemblage, without departing from the scope of the invention. j

Having new described our invention, what we claim as new, is
