SCHMITZ, or new Youn, n. x,
COMBINATION LOCK.
Appiication ined February 7, 1922. seriai'iro. 534,675.
To all whom it may concern:
Be it known that I, WILLIAM Scriiirrz, a citizen of the United States, residing at VYew York, in thecounty of New York and vState of New York, have invented certain new and useful Improvements in Combination Locks, of which the following is a specif iication. f
YThis invention relates to improvements in permutation locks adapted to be used on doors, windowsand like closures. The .device consists principally lofl acasing containing elements of vsimple-construc-` tion arranged to operate locking 'bolts' en# gaged in the casing and initially advanced and retracted by means of a handle passing l V.thru the door.
' is accomplished Aby manipulation of a gradp Provision of means is provided for preventing the bolts from retraction until. a series of slotted discs have been positioned to register thebolt end, and rotationof the discs nate. dial mounted on a frsleeve, passing thru the door and causing the discs to be rotated.
Other objects yof importance are attained- Y by the novel construction. and arrangement of parts hereinafter described and shown inv the accompanying drawings', forming a ma'- terial part of this disclosure and' in which Figure 1 is a front elevationalview of a 'Y door and transom showing the device ar#A rangedv thereon.
-, Figure V2 is a planview of the gra-.duated'l dial and mounting plate. Figure 3 is afragment of adoor with the lock attached and having the cover brokenl away to show the interior members. Figure 4 is a right hand elevational view of the same. Y
Figure 5 is' a horizontal sectionalview of the permutation elements as they appear on y the line 5-5 of Figure 3..
yReferring to the drawings, the numeral 'v designates a doorl of.-conventional type secured byhinges 11 to a door casing 1.2, over which is a transom 13A hinged as at 14 and a bolt 15vertically slidable in brackets 16 andk l 17, is adapted to engage within a bracket 18 secured to the top ofthe door casing 19, thus locking thetransom when the bolt is raised by means hereinafter described... A
n tactable with-the upper side of the 'bracket' pin 15- is fixed in the'bolt and` being con- 16, prevents it from dropping far enough to .l Contact with thevbracket'24, the transom be- ,ing freeto be opened er closed as desi-red.
'f The lower bolt 22 passes thru another bracket 26 and is thereby'guided into a recess 27 formed in the floor 28, when lowered. Referrin to Figures 3 and4, the lock in general is indicated. yby the'numeralfiand '.comprisesa base plate 29 having a pair of integral raised blocks 30 and 311 thru'which y are llongitudinally alined openings 4receptive of the slidable cylindricalwlocking bolts 21 A cover plate 32 is supported from the l, and held in position by suitablescrews 34.
An actuating bar 35, angularly bent J at one end, is secured to the upperbolt 21 by a pin 36 engaged thru the bar and bolt, and the opposite` end of the bar is pivotally connected by a shoulder screw 37 to a lug formed at one ,end of a lever 38, having a raised central portion' in which is a transverselopening 39 thru which the lock bolt is free to operate.
' Integral with the top ofthe 'lever'.38, is a pintle y4() rotatablein an opening inthe cover plate-132, and itsproj ecting end 4 1 iss'quared,
receptive'of a key for manipulating'the lever from the insideof the door. n i.
"The, lever 38 is pivotally connected to the ,Y base plate 29 vby a screw '42passing thru the bottom of the lever, inline with the pintle 40 and engaged in the end of alock leverioperating spindle 43 mounted to p ass thru the doorN 10 andthe base plate 29, and secured to the spindle 43,-is ajbevelled disc 44. The
this keyor wrench being removable and in` terchangeable on the squared end of the pintle 41j 'i I ..1 'i v @en angle plate 47 has secured in v,its outwardly extending element 48, a ,pin 149 voperably. extending thru a guide Way 50 and into .an opening 51 crossldrilled 'vinto the locking bolt 22. A link 52is pivoted at one end to the bottom of theang'le plate 47,' the vother end of the link being pivoted to the lug 53Y of the lever 38; ,screws 54 being employed for pivotal engagement. i
Ain the lever 38.
It will also be seen that as the opposite end of the lever 38 is oscillated, the locking bolt 2l, by its connection with the bar 35, is moved reciprocatively but opposite from the locking bolt 22.
The permutation locking elements, best shown in Figure 5, comprise a spindle rotatable in a sleeve 6l passing thru the door l0 and extending into the lock casing.
At the outer end of the spindle 6() is a bevelled disc 62 having graduations thereon numbered from 0 to 100.
A knurled handle 63 is provided for rotating the spindle 60 and is secured to it by a pin 64. A ring 65 is centered by the sleeve 6l and secured to thevfront of the door 10, this ring having a shallow recess 66 receptive of the dial 62 and a line 67 coinciding with the 0 line of' the disc is formed on the face of the ring.
Letters L and R are also impressed on the ring for indicating the lett or right hand f direction in which the dial 62 should be turned to release the locking element-s. l
AA plurality of discs 68j 69, 70 and 7l are rotatably mounted on the inner end ot the sleeve 6l, the discs 69, 70 and 7l having curved tumbler races or openings respectively 7 4, 73 and 72, their inner radii being uniform and their outer radii progressively increasing, producing races of unequal width.
Rigidly fixed in the innermost disc 68 are a pair of widely spaced tumbler pins 75, the same extending through the several races to points beyond the outermost disc 7l.
In a similar manner pairs of pins 76, 77 and 78 are setrespectively in the intermediate discs 69 and 70 and outer disc 7l, all ot the several pins extending outwardly so that their ends are in the same plane.
An arm 79, secured by its hub to the inner portion of the spindle 60, is adapted to contact with these extending pins, upon twirling the knob 63, thereby rotating the discs in either direction necessary to bring the notches 84, formed in all the discs into register as will be further on described, the end ot the spindle 60 being housed in the cover plate 32.
The discs 68, 69, 70 and 7l while free to oscillate on the sleeve 6l, are confined and under slight frictional restraint between the flanged end of the sleeve 6l and the collars 8l and 82, the former being closely adjacent the base plate 29 and tightly iitted on the sleeve 6l.
In Figure 3, the upper end of the lower locking bolt 22 is shown as a parallel sided tongue 83 adapted to enter into notches 84, formed radially thru each of the discs 68, 69, 70 and 7i at a point between the ends ot the tumbler races 72, 73 and 74.
From the foregoing it will be seen that a simple, practical and efficient combination lock has been described and which is operated in the -following manner.
Figure 3 discloses the lock in a position in which the bolts may be repeatedly eX tended and retracted, the locking tongue entering the locking notches ot the discs at cach retraction ot the bolts as they are caused to operate by turning the key or handle @L6 associated with the bolt operating mechanism of the lock.
l/Vhen it is desired to lock the closed door,
the bolts are shot outward and the dial handle turned in either direction, which movement causes the tumbler carrier 79 to contact with the tumbler pins and compelling the discs to be partially rotated.
It will be seen that rotary movement of the discs will cause an overlapping of the notch elements 84, thus preventing the bolt tongue 83 from entering the notches of the discs.
It is further seen that each disc is provided with two tumbler pins, the carrier 79 operating therebetween, and when it is desired to unlock the door the dial is turned in such direction as will cause the carrier to strike the tumbler pins and the discs will be rotated into position allowing the notches to receive the bolt tongue. f
It will be understood that varying combinations may be arranged by varying the positions of the tumbler pins in the discs.
Although the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor changes may be made in its construction, without the eXercise ot invention or conflicting with the scope of the claims hereto appended.
Having thus described my invention, what l claim as new and desire to secure by Letters Patent, is
