ln the accompanyingdraivings in which like reference characters refer tolike parts, l() represents the outer casinglof the -lock having a flange 12. adapted for securing the casing I1() to the inner face ot' a door, not 50` shown in the drawing. At. the opposite end of' the casing 10 is provided a head 13, ivhicli forms the outer end of the lock and intended tobe exposed upon the outer surface of a doo..A The head 13 is provided with apertures 14, which are occu ied by the push buttons or heads 16 "of tie push bars 17, 1S. 19, 20, 21 and 2Q, adapted for operating the lock.

Within the casing 10 is l aninner easing 25 having a head 26 with an annular flange 2T, adapted to be detachably secured to the fiange 12, so that the inner easing and the lock mechanism may be readily Withdrawn from the Casing 10, without removing the latter from the door for the purpose of changing the combination of the lock when desired.

The'inner casing 25 `is provided with anv annular bearing 30. secured therein, to which bearing is secured a disk 31 forming a bearing. The casing is also provided with a disk y324 secured in said casing, formingr a bearing; and a longitudinal bearing is secured between the bearings 3() and 32. Said bearings form supports or guides for the mechanism 'forming the lock` more fully hereinafter described.

The push bars 17, 18, 19 and 2O are adapted for operating the tumbler blocks and are all of similar construction. therefore the.

.following description ot one. .will apply to4 the duplications ot the parts. A plurality of push bars is provided for the purpose of providing different combinations controlling the lock mechanism. Q

The push bar 19 is shown in Fig. 1, is vslidably mounted in the hearings 30 and31 and 4has a portion which is ot rectangular cross-section to prevent its rotation' in said bearings.` The push bar 19 carries apush button 16`at one end which projects through the head 13 at one end of the easing 10 andv adapted to be operated with .the tingersby pushing the button 16 against the action of a. spring 37. into the operative position, and when released the spring'V 37 will return the bar 19 to its normal position. which position is controlled by a stop 38 ou the bar 19. f 'The push bar 19 is provided with a pavvl 39, pi'voted upon a shaft 40, secured in the har 19, and held in operative position by a spring 41 secured on said bar 19. The pawl vse 39 engages a tumbler block 42 mounted upon l a body bar 43, which latter is slidably mounted in the bearings. 31 and 32. 4The body bar 43 is mnved by a. spring 44, into a normal position 'with the one end of the bar 43 against the head 13 of the easing,

which letteracts iis a. stop to limit the uiorenient in one direction. The body bar i3 has a circular portion surrounded by the spring 4-1, und u flut ppi-tion which loruis u shoulderei a'.i;:iinsty which the spring' i4; acts. The fiat portion of the bur itl prevents the bur from rotating in the bearing` 3l.

The tumbler bloeit 2 is udjustubly mounted upon the bur 43 and sind blot-lg 4.2 is provided with teeth 1.8 :idup'ted ,to he engaged by the puiil 40 adapted tor moving the block 42 :ind the body bur til longitudinzilly. The block i2 is also provided with a longitudinal rib `49, having otrausi'crse recess foimedthereim adapted to cooperzitewith a. holt-controlling-nieniber 52! A bolt-controlling-member 5:2 is secured upon :i iongitudinal shut't 53 positioned centrally ot' the casing 10. Said shaft 53 is rotatably mounted in the nearing 32 :itd one end thereof, :1nd the other end is supported upon the portion 55 ot' the central push rod 21, which hitter. is allowed to nieve longitudinally in relation to'v the shaft 53, :is said portion 55 `is adapted toire-ely enter the recess .5G formed in u. shaft The boit-controlliiig-member 52 is in the form of :i dishhaving slots 57 formed in. its periphery in parallel relation with the axis of the shaft 53. rThe rib 49 on the vblock 42 is adopted to occupy the slot 57 inthe disk and hoid the disk and shaft 53 against. rotation. When the block 42 is moved by the push bnr 19 until the transverse recess 50 formed' through the rib i9 of the block is in register with the disk 52, the disk will be tree to rotate, thus releasing the bolt-controlling-member 5:2I and permitting the bolt 64 to be operated as here inefter described.

The push bur 22 is provided with e sliding pluto 78, which is secured to the end portion 23 ofthe push har E22. Suid plate TS is slid- :ihly mounted upon the hearing by ineens of screws 79; pivotully n'iounted upon u pin 8l), secured in theslidiug` plete 7S, is :i toggle-plate 8l, having recesses 82 find 83 loi'iued in the tree end thereof.

The toggrieplute 81' has e. boss 91 secured centrally thereon. Suid boss is provided with :in aperture throughA which .the rod 88 freely passes. When the toggle-plate 8i is 'swung in either direction from the center liuc of the pushhnr 22, the bossy 9i will engage either ofthe springs 86 or 87, placint,r the same under' sutlicient tension so that when the push bar Q2 is signin released, the

phites 89 und 9i) springs SG or ST will tend-to swing the toggle-plate Sl to its'central position as shown in Fig. 4. It will thus be. seen that, when the tumbler block 42 is moved so as to bring the recess 50 in said block42. into register' with the bolt-controlliiig-member 52. the latter and the shaft :1 will thus be released. aud the bolt (S4 muy lbe, shifted by pressing the linger against tlic'butt'on 16, carried b v the push bar 22.

'l`he tumbler block 42 is adapted to be moved by the pawl 39 when thepush bar 19 is moved in\`vardl by pressure. upon thc button 1G on the bar 19. .1 lat-:h pawl. 92

. is pivotally mounted upon a projecting lug 93 formed on the bearing 30. Said latch pawl 92 is adapted to be moved into engagementwith jthe teeth 48 of the block 42 by the aetionot a spring 94. Said pawl 92'automatically engages the teeth ofl the -block 42, as it is advanced by the pawl 39,

and prevents the spring 44 from moving the body bar 43 and the block 42-'towards its -normal position when the pawl 39 1s released .from engagement with the teeth 48 of the block 42. Thus it vwillbe seen that the block 42 and the bodybar 43 may be advanced `intermittently by pushing the pawls 39 and 92 and allowed to ret-urn to its,

push bar"19 b v linger pressureon the button 1G, secured to said-bar 19.

The tumbler block 42 and body bar 43 may be released from engagement with the normal position through the action of the spring 44, by means 'of releasing mechanism,

consisting of the push bar 21, slidably mounted in thevhearing'l land telescoping at its other end with the shaft 53, as above described. Upon the push bar 21 is secured a hub 96 of adruin. consisting of spokes 9T and a. rim 98. The spokes 97`1of the drum are arranged to pass freely between the push bars as shown in Fig. 7 and thus support' the rim 98 of the drum in alignmentv witlivthe pawls 39 and 92. The pawl 92 operates through theraperture 99 in the rim 98 of the druln so that said pawl 92 may project through the druln and' engage the teeth 48 otl the tumbler block.- lVhen the linger is pressed against the button 1G. secured to the push barl 21, the drumis moved so that the rim 9S engages the pawls 39'and 92 simultaneously and,lifts sa id pawlsI out of engagement with the lteeth 48 of the block 42. thus allowing the spring 44 to move the body bar. 43 and the blok 42 back to the original position. as shown in Fig. 1. 'hen the push bar 21 .is again released the spring 100 will'igeturn the push bar 2.1 toits normal positon moving the rim 98 of the drum out ot' engagement-with the pawls 39 and 92', allowing them to eu-v gage the teeth ot' the block 42.

To permit the combination of the lock to be changed, the tumbler block 42 -is ad formed.

The screw 102 is threaded into ar lug' 104 formed upon one side of the tumbler block 42. Vl'heu it is desired to change the combination of the lock the inner casing is removed from the outer casing 1t). The entire mechanism ,of the lock is mounted withinv the inner casing 25, so that it may readily be withdrawn from the casing 10. lVhen so withdrawn," the adjusting screws 102 are accessible through holes 105 formed in the bearing 31, as shown in Eig. 6. By rotating the screw 102, the block 42 may be moved upon the body bar 43 into ditl'erent positions, so that the -block 42 will have to bemoved different distances by the pawl 39, to be put into a :posit-ion to allow the transverse recessO, of the block 42 to register with the bolt-controlling-menrber :32 and allow the latter to rotate and thus release the bolt 64. 'Each movement of the push bar 19 by a pressure of the finger upon the button 16,' securedlto said bar, will cause the awl 39 .to move the block 42, one tooth. y adjusting the set screw 102 to a position which will bring the recess into register with the disk 52, when the block 42 Ahas been moved, one tooth, it will be seen that o' e pushing movement of thefbar 19 will bring the block 42 into a position to release the disk 52,01' the ladjusting screw `102 mayle set ,so that two, three or 'more teeth will have/'to bev engaged by the pawl 39, upon successive movements of the bar 19 to bring theblock 42 into a position to release the disk 52. As shown in Fig. 1 an extra tooth 42a is provided upon the block 42 so that if the pushbar 19 is pushed too many times the recess I52 will pass beyond the 4position necessary to bring it into reg- .ister with the disk v52, so that the rib 49 will again lock the disk 52, and prevent the lock from being released. By having two or more push bars and tumbler blocks, such as shown in Fig. 7, in which four push bars 17, 18, 19 and 20 are shown, which are all similar to the push bar 19, and having similar operating various combinations may be obtained by adjusting the differentL tumbler blocks to different' positions upon the body bars, so that a different movement, or different oomvbinations, will beV required for moving each `of the different push bars before the bol-t- 'eontrolling-niember 52 will be free to rot-ate eral tumbler blocks.

lll)

mechanism as above described,

through the lrecesses 50 formed in the sev l The operation of myinvention is as :t'ollows: The different. tumbler blocks are first set by'. the adjusting screws 102, .so ,that a different number of movements Itvill be required by the vdiflerent push bars to bring: the parts into a position to release the lock. 'lhe inner rasinr is" then seeured in the outer easing: with the push buttons 1G projecting and exposed beyond the head [2l ot the outer casing: l0. By pushingr the push button 1G. to more the, push bar 21 inwardly the rim 9S ol' the drum will release the pawls` Ill) and 92 from the several tumbler blocks 42e thus allowing the tumbler blocks and the bod;v bars to return to their normal position by the action of" thesprinns 14, thus looking! the bolt-eonlrolling-member 59, by the tumbler blocks. so that the membeu can not rotate and the -boltltll will be held in eitherc the incl-:ed or unloz'ked position. To release the lock the push bars 17, 18, V19 and 20 are each pushed the required nurn-I ber ot times) aeeording to the eou'ilmuition .into which the tumbler blocks are set. These successivemovements will bring all oi the tumbler blocks into a position so that the recess o() will register with the bolt-controlling-member 52, which latter is thus released and Jfree to be rotated. 'lhe push bar 2Q is now moreel inwardly by pressing' u )on the button 1l). secured to said bar 212. wiieh movement slides' the sliding plate 78 and the toggle-plate 8l inwardly so that the latter will press, against a finger T5 or 76. on the pivot plate G7, and turn the pivot.

plate (i7 about' the'pivot pin 68 sullieiently to allow the spring to slide the bolt 64 into the opposite position. Each movement ot the bolt G4 will swing.;q the pivot plate (3T into a position so that either the finger A or the finger 76 will be in a position ready to be engaged by the toggle-plate 81. and successive. Wishing movements upon the push bar 22 will shilt the bolt (il into opposite positions. 'l`o again lock the parts so that the bolt.- tl-l can not be moved, it is only necf essary to press the lmtton 16. secured on the push bar 2b so that the rim 98 of the.

drum will release all the lpawls 39 yand 92 and allow the tumbler blocks 42 to return to their normal positions' and thus lock the bolt-controlling-member and the bolt. 64 against further movement.

ln the p'tesent embodiment of my` invention. I have shown the improved lock mechanism arranged in a cylindrical barrel or easing. whereas the mechanism may be ar- `ranged in a. casing of rectangular cross-seeton or in flat formation adapt-ingr the saine tfor a pad lock as illustrated in Figs. tl to 12,

which changes may be readily nuule. \vithoutV departing Jfrom the seope ot' my invention.

The embodimenty oll my invention disclosed in Figs. 8 to l2. eonn'nises teleseoping casinos 110 and 112 of'flatreetaufrular tormation. in which the pushbars 115. the latch operating bar 116 'and tlie'releasing bar 117 nre arrangedlin the same plane, or approx-- 12T formed througgh which tumbler blocks 130 are `movl able bythe push bars 115. Each block 130 is provided with a recess 131 which may be brought into register with the bolt-controL,

ling-member 1:25, thus releasing the latter from lockingr engagement with the tumbler blocks 130.

There is a tumbler block 130 associated with eaeh ofthe push bars 115,'whi'cl1 are duplicates. thus only one is shown in Fig. 8 (rt-the drawing. The push bar 115 has a paul 1533 pirotally mounted thereon` adopted for engaging -with ratchet teeth 132 'formed upon the tumbler block 130. By pressing' `Said member 125 hasA the button and moving the push bar 115 ini wardly against the spring' 135. the paivl 133 will more the tumbler block 130 in 'relation to the.bolt-controlling-member 12.V into a position to release the latter. providing the bur 115 is moved the proper number 0f times according to the combination at which the loelt set. flateh pawl 123i' is pivoted upon a bearing lill formed on the casing 112, and prevent-s the return niovement lot the tumbler block 130. when the tumbler block is moved by the pawl 133.

vThe tumbler block 1230 is morably mounted upon abody bur 13S and may be adjusted into different positions upon the 'body bar by means of a set screw 140` movable with the body bar. By means of said set'screw the tumbler bleek may be set in different positions upon the respective body bar s0 as toehnnge the combination formed by the several different. tumbler blocks of the lock, in the manner above described. bar 138"'is slidable longitudinally in bearings'ltl und 142 forme-d upon the casing 112 and is movable to a normal position by ineens of a, spring 143 positioned between When all of 'the tnn'xblerblocks. been Il moved. by tliepush bars 115 into a position to release the bolt-oontrollingfmember 125y the, latter may be movedlongitudinally 'in the bearings 126 bv means of thelateh ope-rating" bar 116` which is also4 movable by ineger pressure npona button upon the-bar y 110. Upon the inner/emi ot the bur 11.6 is pivoted a link 146 which in turn is pivotally eonueeted to a latch operatingr lever 14"'.

which in turn if pivotel upon a pin 14S- Tlie'latch operat--y ingrr lever '1471s fprovided with 'a slot 149, which is occupied by aL' lin "150 secured in.

seeured in the casing' 112.

The bodyl fao tbe bolt-controlling-member 125, so that when the ,lever 147 is operated by the push bar 116 and rotated about the pin 148, the bolt-controlling-member 125 will be' moved longitudinally in the bearings I126 by means of the pin 150, being engaged and acted upon by the lever 147. T he tree end of the lever 147 engages a pin 1"2 upon the hitch bolt 153 and is adapted to move .said bolt out ot Vengagement with the shackle 155, which is pivotally mounted upon a pin 156 secured in the casing 112.

When it is desired to more the parts intolocking position, the release bar 117 may be moved inwardly by linger pressure upon the button upon said bar 117, so that a crossbar 158 secured upon'thev inner end of the push bar 117, will be moved under all of the pawls 133 and 137 and lit't said pawls out of engagement with the teeth 132 of the tumbler blocks 180, thus permitting the springs 143 to return the tumbler blocks 130 and body bars 138 to 'their normal positions,

in which the tumbler blocks will again enter Yso the recesses 127 formed in the bolt-controlling member 125 and prevent the latter from sliding longitudinally. Unless said member 125 is released from engagement with the tumbler blocks and free to more longitu-` dinally, the pin 150 thereon, will prevent the latch controlling lever 147 from moving about the pivoted pin 148, thus the operating bar 116 will be automatically locked.

All the parts ot the lock mechanism are carried upon the inner casing 112, which may be withdrawn from the outer casing 1i() by removing a screw 160, which extends through the opposite walls of both casings, as shown in Fig. 9.v The screw 160 is provided with a Hat surface 161. against which the latch controlling lever 147 is held-and prevents said screw from rotating when the loclmechanism is in the locked position, therefore it is necessary to shift the lock mechanism into the unlocked position before said screw 160 can be rotated and removed from the casin'gs. lVhen the casings are separated the heads of the adjusting screws 140 are accessible through the open end of the inner casing 112, thus permitting said screws to be turned for setting the tumbler' blocks into different positions upon the body bars and thus change the combination of the lock.
