To all' whom it may concern) die it known that'L CLYDE'L. MANON'; a

citizen of the United States, residing at Fitzgerald', in'the county ofBen -Hill end State of'Geor'gia, have invented" certain neW and useful improvements in Combination-Locks,

of which the following is a specification.

The present'invention relates to improve- I inents in combinationlocks, designed esp'e 'clally for use in connection 1t11-. s aes,=

The two .isets OI emlly for zontel'guide; hers'end hold the'f lz tchesinf 1 r V n journals 32 inthe ClllQClIlOIl. or the arrows tothe dotted lineposition of Fig. 4, and the movement of the framers so timed that it position, while each carrier has a supporting arm 39 at each end thereof to which the bars 32 are fixed.

All of the latches or tumblers 31 are iden tical in shape and size, and each is formed with a single notch 41 at its free enlarged end orhead and a cam face or edge isalso provided, against which the detents 27 and 28 vof the depressible bar22 are adaptto en a e one latch onl of its set i. e. the V b b J v latch selected in the combination which is set, up n each case. The latch frame or keeper is adapted to have a vertical reciprocalmovement, andis guided inits move mentby any suitable means such as the guide lugs traveling in'suitablegrooves '45" indicated in dotted 'lines, in the walls of the. chamber. 1 I g 7 At 46, the upper cross bar of the latch frame is slotted to receive the end of a lifta ing arm 47 pivoted at 48on a bracket 48 forming part of the bracket 20 and the other end of this lifting arm is looselypi-voted'on thepin 21 of the link 18. As indicated by the dotted lines and arrows, as the depressible bar 22; is depressed, the latch frame '42 is lifted, the movements bearing definite relation to one another as presently described. The bar and frame are so arranged in theirmovement that as-the bar. is depressed, contact'of detents 27 and 28 with the cam facesg40 of certain of the latches;

force, the said latches to ,swing on their is lifted to bring-the lower bar 43 a nd intermediate bar 44 into the notches 41' of: thelatches so shifted. Inthis manner the selected latches are brought to :position where the frame may lock them in'iiiactive position, after which,-by slidingthe sets of latches backto the zero points, the arm 22 will be prevented from raising by the other latches stillinactive position, thus locking thebolts 7; against withdrawal. ,To open,

7 it is necessary to first again shift the sets of latches through the knobs 6, 6 until those latches previously locked in inactive p0sition,Jas just above described, are again EoppOsite the d'etents 27 and 2810f the member 22 so that the latter may be raisedas the bolt throwing handle 5 is manipulated to withdraw the lock bolts 7,-it being obvious that the respective'latches will be released by the frame 42 immediately upon the ins sage ofthe' detents 27 and 28, thereby so that the partsmay again 'assumethe position shown in 4. In other words, in

the present arrangement a member is provided wh1ch'1s depres'sible when the lock bolts arethrust into the locked position togetherwith certainmeans to prevent the said depressible member from being again V elevated and the last mentioned means'being' selective-to the extent that certain of the I latches constituting the same may be shifted and secured in inactive positionpso that'the depressible member is thus given a path of elevating movement, throughthe series of latches, although it requires thatthe thelock,.t'o the same position they occupied when the lock was secured. V

In settingthe combination, the latch to latches shall be again shifted, in rele'asing be engaged by the latch frame-is selected 7 through the medium of the knobs 6 and 6', and the journal bars 32 of the latch sets are fashioned at their endsinto rackbars 49 and V 50 which are engaged by the respective toothed segments 51 and 52 'on:the spindles 53 and 54 of the respective knobs 6 andfi The knobshave the arbitrary designations 1O, 20, 80, 40, 50 and five corresponding lines equaling the number of latches in each set,

dicator mark for each knobr In tlie drawr ings, in the upper set of latches,-the middle latch, or the latch corresponding to 30" i and these lines of course oo-act with the in-" has been selected," and inthe lower set the second latch 207-"has been selected. :The latch sets are so positioned and supported on their guide bars 35 and 36, that when the Fig. 5, the mark 10 will be at the right of the'indicator mark, or at the left there0f,as

desired, but the space for the sets to move in is suflicient of course to allow the required movement of the sets. 7 Thus, when the. knob 6 is moved to position for 10 to register with the indicator mark, the first latch at the left inthe setswill'be brought, through the action ofthe segmental rack andrack bar, into lineiwith the depressible bar 22.

Then, as shown 'in-dottedlines iIiFig. .1,

when the knob 5 is turned, the bolts are shoved into theirsockets, the two latches are moved by their cams and the frame with its latch bars are brought to position to hold the-latches through engagement with their notches 41 ,By giving the knobs 6 and 6 a slight turn thelatch sets are moved so that selected latches. g In Fig. 4 the device is shown'unlocked. el Vhen locking the device the two knobs 6 the cam bar may be out of register with the and 6 are set onjcorresponding numbers say 10 and I 10, then turn knob ,5,i.which draws bar 22withca'm arms or detents27 and 28 downward over cam faces 40 and 40. When the detents 27 and 28 are approximately two thirds over thelatches 10 and 10' .the'keeper bars43 and 44 are drawn to the 100 sets are at theirl extreme left positions in edges of notches ll and 41 by the lifting arm 47 and as the detents pass over the latches the keeper bars are seated in the notches. The knobs 6 and 6 are then turned back leaving the latches 10 and 10, down in inactive position and four otherlatches in each set are left up into bar locking position.

1 What I claim is l. The combination with a'set'of laterally movable revoluble latches, and means for adjusting the latches to selected position, of

a depressible bar adapted to engage a selected'latch, a liftable keeper frame adapted V latches supported on said rail, means for actuatingthe latches, a keeper for holding a selected latch, and, means for moving a selected latch forengagement with the actuating means I I a v 3; The combination with a locking bolt, its spindle, and actuating mechanism between the spindle and bolt, of a plurality' of sets of latches each latchprovided with a notch and 1 revolubly'supported, means for adjusting each set to selected position,)'a

depressiblebar for moving a selected latch,

in each set, a keepe'r frame having a keeper bar for each selectedlatch,and means actu ated from the spindle for operating said cam bar and keeper frame, as described.

, In testimony whereofI affix my signature.
