LE GRAND C. BUSH, 01E-CHICAGO, ILLINOIS, AND JOSEPH F. COLE, OF ELKE-ART,

INDIANA, ASSIGNORS 0F ONE-THIRD T0 WALTER J'. MULLER, OF AURORA: ILLI- NOIS.

To all whom it may concern:

Be. it known that we, Lr. GRAND C. BUSH and JosErH F. COLE, both citizens of the United States, and residents, respectively,of Chicago, Illinois, and Elkhart., Indiana, have invented certain new anduseful Improvements in Recording Door-Locks, of which the following is a specification.

This invention relates to door locks of that type used to some extent on stores, factories, warehouses, and similar buildings, which are provided with a plurality of keys for manipulating them, designed to be carried by different parties having authorized admission to the building, and which are further provided with means for recording the particular key by which the lock is operated at any time and hence disclosing the person using such key, and are also ordinarily further equipped with a time-recording mechanism for making a record of the times when the lock was operated. In locks of this character as hitherto constructed it has heretofore been customary, so far as we are awaremechanisms; the time recording mechanism being actuated more or less directly from each of the several kevs which actuate the bolt, and the key-recording mechanism being set to the proper position to record the particular key employed through dierentiating means wholly or partly embodied in or on the keys themselves.

The main object of the present invention is to produce an improved lock of this general character; and the principal feature of novelty which the invention presents, broadly considered. consists in the location of all of the recording mechanism at some point or place outside of and more or less distant from the lock itselfand its actuation by electrical energy through circuits which are controlled primarily by keys or,V other differentiated tools. such keys or tools having, however. as their functions to effeet the proper control of the electric circuits and also the control of a bolt-actuating device, but not in themselves effecting the actuation of the boltin either direction.

In the accompanying drawings we have g illustrated one. practical form in which the principle of our invention may be embodied, i I

l spectively, which keys are ditierentiated in and referring thereto- Specification of Letters Patent.

Fig. 14 is a perspective detail of the key indicating segment. Fig. 15 is a group view of a series of differentiated keys adapted to be used with the lock. Fig. 16 is a diagram showing the electric circuits and circuit connections between the lock mechanism on the door or door casing and the recording mechanism located at the otiice or other place remote from the lock mechanism. y

Referring to Figs. 1 to 6 inclusive, which illustrate that part of the mechanism adapted to be mounted on the door or door casing, 1 may designate a portion of the door, to the inner side of which is secured, as by screws 2, the casing or housing of the lock designated as an entirety h v 3. 4 designates the tumbler-barrel of the well'known Yale pattern, which is mounted in the door respect to length, as shown in the detail view Fig. 15. In the lower part of the lock casing 3 is the locking-bolt 5, the stem or shank of which has slots 6 by which it is slidably mounted on bolts 7 projecting from the back plate 3a of the lock casing. r1`he shank of the bolt is also provided between the slots 6 with an opening 8, the upper edge ol which is formed with a vertical notch 9. In a hole lformed through the door 1 below the Yale section 4 is rotatably mounted the shank 10 of'a bolt actuating knob 11; and to the inner end of the shank 10 is secured a disk. 12 from the front face of which projects an eccentric pin or roller 13. The shank 10 and its knob 11 and disk 12 are adapted to have a. limited sliding Inovement as well as a rotary movement, so as to carry the roller 13 into and out of engagement with the opening 8 in the shank of the bolt, the parts being shown 'in their normal retracted position in Fig. l. The disk 12 is normally locked'against. inward movement by means` of a locking bar 14 that is mounted to have a limited vertical sliding movement upon and relatively to the back plate 3fL of the lock casing, said 'locking bar being guidingly supported by means of pins 15 which engage slots 16 in said bar, said pins 15 being mounted in the back plate 3n and in an intermediate frame plate 17. The locking-bar 14 is formed with an enlargement 18 near its upper end (Fig. 2) in which is a segment-shaped opening 19 adapted to be engaged by a key-actuated device for raising said locking-bar. This device comprises a slide 20 that engages a. slot in the inner end 4of the rotatable tumblertube 4a of the Yale section 4 and also a similar slot in the hub 21 of a disk 22 that lies in a recess 23 in the back-plate 3a of the casing. On the face of the disk 22 is a pin or roller 24 that projects into the segmental opening 19 of the locking-bar and, through engagement with the upper horizontal edge of the latter, raises said locking-bar out of locking position relatively to the bolt-actuating disk 12 when the key is turned half way around. On the outer end of the slide 2O is a depending flange 25 (Fig. 1) adapted to be engaged by the inner ends ot' the keys B. C,Aand D of varying lengths. whereby said slide will be pushed inwardly to varying extents according to which of said keys is used: it being unnecessary in the arrangement shown that the shortest key A should effect any longitudinal movement of said slide. Integral with or secured to the inner end of the slide 2O and projecting through a hole in the center of the disk 22 is a rod 26 that has a swiveljoint connection 27 to a contactarm 28, this latter being hinged at 29 to a bracket 30 .secured to the back-plate 3". The free end ot tlu` arm 28 rests on a support 31 (Figs. 3 and 6) secured to the back-plate 3a,

'mg-bar normall and near' its free end it carries a contact member 32 that is pressed upwardly by a spring 33 into engagement with the lower side of a bracket 34 that projects from the base-plate 3al and constitutes a support for a series of four stationary contact members 35, 36, 37 and 38. The arm 28 is normally impelled to the position shown in Figs. 3 and 16 by a spring 39 connected to said arm and to the back-plate 3.

Projecting from one edge of the lockin bar 14 is a contact member 40 that, when the locking-bar is in its lowered position, forms an electrical connection between a air of contact-strips 42 secured to the bac -plate 3 and suitably insulated therefrom and from each other, and, -when the locking-bar is in its raised position corresponding to a half-turn of the key, forms an electrical connection between a similar pair of contactstri-ps 43.

The front-plate 3b and intermediate plate 17, of the lock casing and frame support devices for actuating the locking-bolt and controlling the bolt-actuating means, as well as for controlling certain circuits through which is recorded the fact of the lock having been operated from the inside. These devices are substantial duplicates of parts alread pointed out, but may be briefly described as follows. 44 designates a knobshank and 45 a knob secured to the outer end thereof, the two being slidably supported and guided in the frontand intermediate plates 3 and 17, and said shank having fast on its inner end a disk 46 carrying on its innerface a pin or roller 47 that, When the knob is pushed inwardly, enters the opening 8 of the bolt in a position to actuate the latter when the knob is turned. 48 is alocking-bar similar in function to the lockingbar 14 mounted to slide vertically on the 'pins 15 which engage slots 49 in said bar (Fig. 4). The lower offset end of said lockoverlies-the inner face of the disk 46, as c early shown in Figs. 1 and 4, and prevents the inner knob from being thrown into operative engagement with the bolt. A circular enlargement 50 near the upper end of the bar 48 is formed with a segment-shaped opening 51 within which operates a pin or roller 52 eccentrically mounted on the inner face of a disk 53 secured as by a screw 54 to the inner end of the tumbler-tube 55 of the inner Yale section 56. Projecting from one edge of the locking-bar 48 isl a contact member 57 that, when the lockin -bar is in its lowered position, forms an e ectrical connection between a pair of contact-strips 58 (Fig. 5) secured to the plate 17 and suitably insulated therefrom and from each other. and. when the locking-bar is in its raised position correspondinsT to a half turn ot the key, forms an electrical connection between a similar pair Aao ing of either knob in either direction by the engagement. of either of the rollers 13 and 47 with the lower end of a latch releasing pin 66 slidably mounted in the upper portion of the bolt-shank, its lower end extendingrinto the notch 9 of the latter.

he above-described parts represent a `typical embodiment of that portion of thel complete mechanism that is designed to be applied to the door itself or its casing., The mechanism for making a record of the times when thelock is operated, the keys by which it is operated, and whether it is operated from the outside or the inside, is located outside the lock casing and preferably at a 'greater or less distance therefrom, such as in the ofice of the buildin v; and it is operated by electrically actuaba means, the circuits.

of which areoI nedand closed in proper order and 'relation to eect the proper postioning of the printingxwheels, the actuation of the printingI platenand the feed of the paper and ribbon of the'printing mechanismcertain of the key-actuated'parts of the lock and circuit making and breakingdevices set in operation by the latter, all as will be now fully described in detail.

Referring to Figs. 7 to 15,inclusive, which show the part of the mechanism intended.

` to be located in the oice or elsewhere outside of the lock casing, 67 designates a supporting base and 68 a vertical wall strongly secured thereto as by the brace 69, on which base and Wall are mounted the recording devices and their controlling and operating means. On a horizontal shaft 70 mounted substantially centrally ofthe vertical wall 68 is pivoted a key indicating segment 71 shown in detail in Fig. 14, said segment bearing on its printing edgev the charactersl, A, B, C, and D, inthe order named; the

letter I designating the word Inside and indicating the operation of the lock from the inside, and the letters A, B, C and D indicating the correspondingly identified keys. On the same shaft 70 are also mounted a series of type disks such as the disks 72 designating the days of the Week, disks 73 designating hours, the disks 74 and 75 designating, respectively, Lthe units and tenths of a minute, and disks 76 designating A. M. and P.vr M. These several time-indicating printing disks are moved in properly timed. relation to each other by a series of pawls coperating .With suitably formed ratchets on the sides of the respective disks,

and themselves actuated from an electromagnet 77 through a lever 78, link 7 9 (Fig. 11) and yoke`80 on which the actuating pawls are carried, coperating with suitable spring-pressed detent pawls .Stand 82 to prevent overthrow and backward movement of the disks. lVith the details of this printing mechanism our invention is not concerned` as the mechanism is old-and well known, and for a more complete description thereof reference may be had to the patent to F. v Hubbard No. 717,405. granted December 30, 1902. rl `he magnet! 77 is energized once each minute by the closing of a circuit which includes the winding of the magnet through a pair of normally separated spring contacts 83, 84: by an eccentric pin 85 (Fig. 7) on the face of the escape-k ment Wheel 86 of an ordinary clock-train indicated as an entirety at 87 mounted uponl `andisuppo'rted by the supporting wall 68 above the type wheels of the printing mechanism.

` @n the base 67 are mounted side-by side a series of four electro-.magnets 88. 89, 90 and 91 (Fig. 9), opposite and parallel with the upper ends of which is mounted in the Wall 68 and an upright 92, a shaft' 93, on which latter are loosely mounted the hubs of a series of armature arms 94, 95, 96 and 97, cooperating with the magnets 88, 89, 90 and 91, respectively. The hubs ofsaid armature arms are provided at one end, respectively, with radial shoulders 94, 95', 96 and 97 which, when the armatures are attracted by the magnet, coperate with similar shoulders 98', 99', 100' and 101 on collars 98, 99, 100 and 101 fast on the shaft 93 and alternating with thev hubs of the armature arms. V The shoulders 98', 99', 100 and 101 are disposed at, different and consecutively increasing an-- guiar distances from the shoulders 94e', 95', 96 and 97, which latter are all disposed in a line parallel with the shaft 93 when the armature arms are intheir normal elevated positions, as clearly shown in Fig. 9. The result of this construction is that 'the several magnets 88, 89, 90 and 91 can operate independently upon the 'shaft 93. and each, when energized, imparts to said shaft a slight,l turning movement, these' movements varying in extent according to which magnet acts. The main function of the magnets 88, 89, 90 and 91 is to set the key indicating segment 71 to proper printing position, according to which key is used. The mechanical transmission from thev shaft 93 to the key indicatingL segment "71 consists, asbest shown in Fig. 7, of a short arm 102 fast on one end of the shaft 93, a llink 103 connecting the free end of said arm .with the shorter arm of an elbow lever 104; pivoted at 105 to the wall 68. and a link 106 connecting the upper end of the elbow lever with the upper end of a radial arm 107 (Figs. 10 and 14)\130 of the key Iindicating Asegment 71. The elbow lever 104 is normally drawn to a position corresponding with the I printing positiouof the key-indicating segment by a spring 108 (Fig. 7), the movement of said elbow lever in suchdirection being limited by a stop-pin 109. r1`he several armature arms 94, 95, 96, and 97 are normally maintained in raised position by suitably applied springs, such as those indicated at 110. Fast on the opposite end of the shaft 93 is a depending arm 111 having a pin and slotl connection 112 with the upstandin arm 113 of an elbow lever pivoted to the p ate 92 at 114, the other arm 115 of said lever constituting a contact device to alternately open and close electric circuits between two pairs of spring contact strips 116 and 117, respectively, secured to and insulated from the plate 92.

Referring neXt to the printing platen and its actuating means, 118 and 119 designate, l respectively, a pair of twinspool magnets mounted on the base 67, between land'parallel with the upper ends of which is a shaft 120.

journaled in the side wall 68 and an upright f 121. Fast on this shaft 120 are oppositely extending twin armature arms 122 and 123 that=coperate with the magnets 118 and 119, respectively. Rigidly Secured to one of the arms 122 (Fig. 9) is an angle-bracket 124, -to

' which is pivoted the lower end of a link 125, the upper end of which latter is pivoted at extendingv arm 131 that lies acrossv the upwardly extending arm of the elbow lever 104, and is provided on its lower edge with a series of notches'132 adapted to coperate with a tooth 133 on the side of the lever 104 l to insure the exact alinement of the type of the key indicating segment, and a guard against any possible inaccuracy in the actuation of said segment by any of the magnets 88, 89, 90 and 9 1.

134 and 135 designate, respectively, delivery and receiving spools for a paper strip ortape 136 that extends beneath the type `carry1ng elements of the rinting mechanism and beneath anidler ro er 143, as clearly shown in Figs. 7 and 10; said spools being rotatably mounted on suitable spindles 137 and 138, respectively, -project in from the vertical wall 68. Beneath the de ivery spool 134 and rotatably mounted of the kno on the spindle 139 is a. delivery spool 140 carrying an inking ribbon 141, which ribbon is passed over idler rollers or supports 142 and 151 and thence around a relv' vspool 144. Receiving spools 135 and 144 'are intermittently driven b a pawl and ratchet mechanism actuate in' properly timed relation to the printing operation from one of the armature arms 123. The mechanism shown comprises ratchets 145 and 152 on correspondin ends of the spools 144 and 135, respective sprin -actuated pawls 146 and 153 engaging sai ratchets,

a link 147 on which saldpawls are pivoted,

a bracket 148 (Fig. 9) secured to the armature arm 123 and to which the lower end of the link 147 is pivoted, and a radius arm 149 pivoted on the spindle of the spool 144 and at its outer end pivoted to the link 147. The usual detent pawls or dogs 150 and 154 are also employed to prevent back movement of the spools 144 and 135.

Fasten one end of the armature shaft 120 is a depending arm (Fi 7) 155, the lower end of which carries a aterally projecting pin'156 engaging a vertical notch 157 in the upwardly extending arm 158 of a double bell-crank lever, the other arms of which 159 and 160 constitute contact-members adapted to operate between two pairs of contact strips'161 and 162 supported u n andsuitably insulated from the stan 121. 126, (Fig. 12) to a platen frame or carrier One practical arrangement of the circuits connecting a battery orv other source of electric current with the several electro-magnets and contact devices described is shown di amniatically in Fig. 16, such am `mii'iirtr being operative with the use ofnlgnit a single battery or other source of current. The arrangement of the circuits asshown by this diagramwill be readily understood .when considered in connection with adescri tion of the manner of operating the lmec msm.

. The various parts are shown in the drawings in the relative positions which they occupy when the door is either locked or unlocked, exceptin only that when the door is locked the bo t 5,'which appears in Fig. 2 in the unlocking position, is in the locking position. Assuming that the bolt is shot an .the'do'or is locked, and is to be opened from the' outside by'al person carrying the A key,

' the said key is first inserted in the tumblertube 4., as shown in Fig. 1, and is given a half turn. This, through the tumbler-tube slide 20, hub 21, disk 22, and concentric in 24, raises the locking bar 14 out of inte eren'ce with vthe disk 12 of the bolt-actuating knob 11, allowin the latter to be pushed inwardly sov that t e pin o r roller 13 engages -the'openin 8 of the bolt. A complete turn 11 throws the bolt'to the retracted posit/ion shownv in Fig. 2, the en- 13 gagement of the roller 13 with the in 66 effecting the release of the latch 60 )ust efore said roller, through engagement with the notch 9, shoots the bolt. The knob having been completely turned is retracted either manually or by a spring such as that shown at 11a in ig. 1. The recording of this unlocking operation and of the fact that it was performed by the A key is effected in the following manner. The raising of the locking bar 14 establishes, through the contact plug 40, the closing of a circuit through the contact strips 43, the circuit being from one pole of the generator Z (Fig. 16) through wire a, wire h, contact strips. 43 and plug 40, wire k, contact strips 116 at such time closed through contact arm 115 (see Fig. 7), wire l, bar 31 to which wire Z is connected (see Fig. 2), arm 28, closed contact-s 32 and 35 (Fig. 6), wire p, magnet 88, wire v, and wire I) to the opposite pole of the generator. This energizes magnet 88 which, through the armature of said` magnet and the described connections therefrom to the keyindicating segment 71, turns said segment to the A-pri'ntingposition. The turning of the shaft 93 by the armature arm of the magnet 88 shifts thecontact plug represented by arm 115to a position opening the circuit between the contact strips 116 and closing a circuit between the contact strips 117. ,This, it will be seen, establishes a closed circuit through the printing magnets 118, the circuit. being from one pole of the generator Z by Way of wires a, g, contact vstrips 117 and plug 115, wire z', magnets 118,

wire j, contact strips 161 and contact plug 159 (see Fig. 7), and wires d, and b, to the -opposite pole of the generator. This energizing of the printing magnets 118 instantly followingthe energizing of the segmentpositioning magnet 88, actuates the platen and the segment alining mechanism through the connect-ion shown and described and thus effects the printingon the ltape 136 of the time andkey designating symbols. The energizing of the printing magnets 118 through their armature arms, and the jointed arms 155`and 158 and the contact plugs 159 and 160 opens the previously established circuit at the contact strips 161 and places the contact strips 162 into electrical connection with each other, the circuit including said contact strips 162 being, however, open at this time bet-Ween the contact strips 42. The key is then given its remaining half turn, which lowers the locking-bar 14 into locking` position relatively to the knob 11, and at the same time carries the contact plug 40 from between the contacts 43 to closing position between the contacts 42, thus closing the circuit through the relief magnets 119, such circuit comprising the Wirea leading from one pole of the battery, contact strips 42 and plug 40, wire e, contact strips 58 and plug 57, wire f, magnets 119, wire g, contact strips 162 and plug 160 and Wire to the opposite pole of the battery Z. The energizing of the relief magnets 119 restores the contact strips 162 to normal open position and effects the feed of the printing tape and ribbon by means of the receiving spools 144 and 135 and the described actuating mechanism thereof connected to the armature of the magnets 119.

The above described operations occur both in the locking and unlocking of the door from the outside, and also when using any one of the series of keys Then using the B, C, or D key, however, thevinsertion of such key in the tumbler-tube shifts the arm 28 into engagement with the contacts 36, 37 or 38, so that upon the closing of lthe circuit at Athe contacts 42 the magnet 89, 90 or 91 is actuated -through the circuits thereof clearly shown in Fig. 16, and the key-indicating segment 71 is 4thereby actuated to the proper extent to effect the printing of the symbol I corresponding with the symbolvdesignating the key used.

In the normal position of the key-indicating segment the character I thereof lies in the printing position, and hence, when locking or unlocking the door from theA inside it is unnecessary to call into action the segment-positioning mechanism. In locking or unlocking thedoor from vthe inside any one of the keys may be used, the release of the inside knob and the subsequent actuation of the bolt thereby being effected in the same manner as that already described through the substantially duplicate mechanism shown in the inner portion of the lock. The turning of the key half .way around carries the contact plug" 57 (Figs. 4, 5 and 16) from the position shown in said figures to a position connecting the contact strips 59.

This establishes a circuit throughthe printing magnets 118,' such circuit comprising the wire a, from one pole of the battery, wire 71 contactstrips 59 and plug 57, wire 2', magnets 118, wire j, contact strips 161 and plug 159, wire d, and wire b, to the other pole of the battery. i The energizing of the magnets 118 also breaks this circuit as soon as the printing is done, and closes the contact strips 162 through plug' 160; whereupon,

upon the completion of the turning movetrolled primarily by the key-actuated circuit-closing means carried by the lock mechanism. This greatly simplifies and reduces in size the lock mechanism -proper carried by the' door or its casing as compared with those devices wherein the recording mechanism is itself mounted within the lock casing and is primarily actuated from the key itself. It will also be observed that in our invention the element We have termed the key isnot used to actuate the bolt of the lock, but finds its principal function in selecting and controlling certain electric circuits pertaining to electric magnets or like motors through which the key-indicating segment is moved to proper printing position and through .which the printing or recording is done, including the feeding of the inking ribbon and paper strip and the restoration ofthe circuits to their normal position upon the completion of the locking or unlocking operation. A further function of the tool which We designate'as a key is in controlling, through locking devices, such as the locking bars 14 and 48, the operative connection between the bolt and the knob which effects the throw of the bolt.
