y'Iiigli're 1,8 illustrates'akey'of ythe type used for operating .the lock constructions of the present invention.

Ther-onstruction ofthe lock `rof Figures l to 7 'inclusive' 'will-first be described; Said lock rcomprisesthe' shacklef membergenerally designated atA-iandincluding'fthe'body I and the approximately U-shaped shackle 2. Associated with the 'shackle member'A`l is the closing member generally-.designated atjB comprising the endl extenysion 3-having the socket or seat 4 formed therein The berand ofr largely the same dimension, whereby to provide a proper proportioning of the lock structure.

The connection between the body parts I and 5 is established by providing a sort of Tinterlock ing groove structure provided by forming the body portion l with side tongues .6 and ladjacent grooves In turn the grooves I receive the tongues 9 on the closing member 5, the latter4 having grooves 9 to receive the tongues 6 of the body I of the shackle member A.

By the provisions of the interlocking parts or portions 6, l', 8, and 9, above described, it will be apparent that the shackle member A and the closing member B are relatively slidable one upon the other in the direction of the longitudinal axis of the lock. If desired, the member B may be cored out as at I to decrease the weight of the part. Y

Suitable tumbler locking mechanism "is provided intermediate the members A and B and is mounted upon the jaws I and 5, respectively, thereof. -This tumbler mechanism may be of any suitable or conventional type, but that illustrated is of the class known as concentric sleeve or barrel mechanism, as set forthin my United States Letters Patent Nos. 11,390,222 and 1,597,560 heretoforegranted.

As seen in the drawings, said 'tumbler parts include cylinders or sleeves II mounted in a cored opening or recess I2 of the body 5 `of the closing member Band disposed in alignment with. similar cylinders or sleeves I3 carried in a similarly cored recess or opening I4 in the shackle member A. Of course the openings I2 and I4 of the parts B and A respectively are adapted to be aligned and the inner contacting faces of the parts A and B, as shown at I5, establish a line of cleavage such that when the adjacent ends of the cylinders I I and I3 are brought into alignment with said line of cleavagel the tumbler mechanism permits the relative sliding movement of the parts A and B to open ther lock. When, liowevenany of the tumbler cylinders or sleeves project across the linel of cleavage of the contacting faces I5 lof the parts A and B,Vthe said parts A and B are locked firmly together ,against any opening movement as seen according to their positions in Figure 1. Y I v The keyhole side of the lock is the side comprising the body 5 of the closing member B, and the keyhole I6 as shown in Figure 2 is of rectangular form so that the outery end of thebore I2 is largely closed and prevents escape or displacement therefrom of the several cylinders of the tumbler mechanism.

By introducing a flat key through the opening I6 to engage the tumbler members I I, said members may be forced inwardly against the tension of certain springs I directly coacting with the members I3, until the adjacent ends of the members II and I3 align with the line of cleavage or contacting faces I5 of the parts `A and B, thereby releasing the locking connection between the parts Aand B to permit the free relative movement` thereof whereby the shackle member A at its shackle 2 is moved away from the closing member B, or vice versa.

For limiting the opening movement of the lock parts A and B the innermost cylinder I3 in the bore or opening I 5 of the shackle member `A is adapted to ride in a recess I8 on the inner'face of the closing member B and the end' of said recess as shown at Ia formsa stop that prevents the shackle part 2, and theV member A in fact,

from being wholly displaced from the closing member B, in an obvious manner.

In assembling the parts of the lock, the springs and tumbler sleeves or barrels of the tumbler mechanism will be placed in the respective recesses I2 and I4 that are to contain the same, the tongue and groove parts 6, 'I, 8, and. 9 will then be interlocked, and as the parts A and B Vslide together the tumbler mechanism will be "enclosed fully and rendered inaccessible for any purposes of tampering, completing the assemblage of the lock parts A and B in an operative manner. Y Y

Figures 8 and 9 of the drawings show aconstruction of lock substantially like the construction of Figures 1 to 7 except that in Figures 8 and 9 the opposite longer sides of the lock are entirely at as shown at C instead of having the protruding rib portions D, see Figure 4, that are providedwith the tongue and groove features 6, 'I, 8, and 9 of the construction of Figures 1 to '7 inclusive, Y Y

The construction ofthe invention in Figures 10 to 13 will now be set forth. According to this The said tumbler barrel I9 is eduipped with Y a toothed pinion 2l at its inner end and said toothed pinion meshes with a toothed rack 22 which is formed on the body I of the shackle member A'.

The tumbler mechanism illustrated is substantially like that previously' set forth, with the exception of the pinion or gear feature of th tumbler barrel I9.

Whenthe key 23 for operating the tumbler mechanism is inserted in the key opening 24, the said key interengages with the' tumbler barrel I9 and by turningthe key, at the same time pressing inwardly thereon, the tumbler sleeves or cylinders are caused to have their inner ends aligned with the contacting faces of the partsy A and'B, and simultaneously the rotation of vthe barrel I9 through the engagement of the pinion 2I vwith rack 22 causes a positive actuating movement to be imparted to the shackle member A to yopen its shackley 2 in relation to the extension 3 of the closing member B. It

' may be noted that the key opening 24 above referred to is in the form of an elongated slot the longer dimension of which is seen best in yFigure 11 and the narrower or transverse dimension of which is shown in dotted lines in Figure 13. The key opening in size conforms with the flat cross sectional dimension of the key and said opening is really formed in theouter end of the tumbler barrel I9. Thus, introduction of the key 23 into the opening 2d interlocks the key with said tumbler barrel I9, enabling the key to turn the barrel after the key at its inner end portions has pressed inwardly the outer sleeves or cylinders of the tumbler mechanism, until the inner ends of these sleeves are aligned with the line of cleavage between the adjacent sides of the shackle member A and the body 5 aforesaid.

member A' is equipped with an extension 22a "projecting, from the lower end of the rack 22 f and forming a stop to limit the opening movement of the shackle member A as its body moves yout of the casing member a.

AIt is apparent from the foregoing that the just described construction affords a means whereby the key for opening or unlocking the lock parts affordsy a positive actuating means for relative shifting of the lock parts to an open position While the tumbler barrel I9 has free rrotary movement, it does not move endwise, as

willbe obvious. Of course, the inward movement of the shackle member A' as it operates rin the casing 5a is limited bythe abutment of .the inner end of the body I with the bottom or innermost portion of the casing 5a.

Another modification of` my invention is shown inFigures 14 to 17which modification will now be set forth. In thisV modification lthe shackle member is designated A generally, having its body I and shackle 2'?. `The closing member is designated 3" as to its extension that coacts v` with the shackle 2", and generally designated as l range of the sliding movement of the part B B. The 'shackle member A in this construction is formed with the casing construction somewhat like the part 5a. shown in Figures 10 to 13, said'casing extension being designated 25 and enfolding or surrounding the closing shackle member B which freely slides in the casing :extension .25r because the casing extension 25 Y -lock parts a little differently. In this instance the closing member B has its bottom 5" formed with ;a horizontal or transverse opening 26 extending entirely therethrough to receive the tum- *f bler parts which are to be carried by this member. The shackle member A is likewise formed l with a lhorizontal opening 21 entirely through 45 the same for receiving and assembling in place rthe tumbler parts carried therein.

However, when the tumbler partsr have been assembled in the openings 26 and 21 as shown in full lines in Figure 14, by passing through or into the openings aforesaid through rthe outer end of the openlng 21, said outer end of opening 21 is permanently closed by a knurled plug 28, after known practice ofy use of such plugs, thereby sealing the ytumbler mechanism in place against accessibility save'for operationby the key which will beintroduced` into the outer end of the opening 26 through a key slot or opening 24".

It being borne in mind that the closing mem- Aber B of the present construction carries certain of the tumbler parts that are required to be forced'inwardly to bring their inner ends to the n Vline of cleavage established by the contacting faces of the members Af and B", whereupon the'closing member B" may be moved out of the casing member 25 for opening of the lock, it is necessary that the slot 24 be considerably elongated, whichV accounts for its construction as seen in Figures I4 and I5. Said slot 24" is `about two times the diameter of' the recess or opening 26 in respect to the length of said slot, and lpermits the key to move downwardly as the parts are seen in Figure 14 when the tumbler mechanism is actuated by the key'to enable the unlocking of the lock. At such time of course the downward movement of the key actuates the closing member to effect the opening operation thereof respecting the shackle member A".

For limiting the opening movement of the closing member B as it slides in the casing 25, the innermost tumbler part carried by the shackle member A is adapted to ride in a recess I8", the end I8 of which forms a stop after the manner of the corresponding parts I8 and I8a in the Figure 1 construction.

It will be evident that according to the constructions of the last two modifications described the key may be employed to initiate and effect the movement of one lock part relatively to the other in causing the opening of the lock, the key being rotated for this purpose in one modification and caused to slide `in respect to the other modification.

Having thus described my invention, what I claim as new and desire to secure by Letters' Patent of the United States, is:

1. In a lock, in combination, coacting locking parts mounted for relative movement in connection with each other, locking mechanism for locking said parts together and releasing them, and key means for said locking mechanism, with gear means operable by the key means for actuating one ofthe lock members to effect movement thereof relative to the other lock member.

2. A lock as claimed in claim l, in which the key actuated means is operable to effect movement of one lock member relative to the other only after the locking mechanism between the members is released to permit such movement.

3. In a lock, the combination of coacting lock parts movable to be opened and closed to assume unlocked and locking positions, respectively, lock mechanism intermediate said parts to prevent relative movement thereof, and key means for releasing said lock mechanism to permit opening of the lock parts relatively to each other, together with an instrumentality separate from the lock parts operable by the key means to cause shifting of one lock part to open position in respect to the other.

4. A lock as claimed in claim 3, wherein the lock mechanism comprises tumblers on the two lock parts adapted to coact with each other and movable by the key means, and wherein the key actuated means to move one of the lock parts includes a tumbler barrel carried by one lock part and geared to the other for actuating the latter.

5. In a lock, the combination of coacting lock parts movable to be opened and closed to assume unlocked and locking positions, respectively, lock mechanism intermediate said parts to prevent relative movement thereof, a pinion to move one lock part relatively to the other, and a key operable to unlock the lock mechanism and coacting with the pinion to actuate the same.

6. In a lock, the combination of coacting lock parts movable to be opened and closed to assume unlocked and locking positions, respectively, lock mechanism intermediate said parts to prevent relative movement thereof, comprising tumblers, a tumbler barrel for the tumblers, a key coacting to unlock the lock parts by coaction with the tumblers and engageable with the barrel to turn same, and gearing between the tumbler barrel and one lock part for moving said last lock part.
