To all w/tom 'ift 71mg conceive:

Be it known that I, FEED J. ViEwEG, a citizen of the United States of America, and

a resident of Plainfield, Union county, N ew.

Jersey, have invented certain new and useful Improvements in Locks, of which the following is a specification.

My invention relates generally to locks, and has more particular reference to the novel construction and arrangement of parts 'which will be more fully described hereinafter.

In my patent of March 21, 1905, No. 785,132, I show and claim a keyless lock, operative at all times from the inside of the door and having' means operable from the outside for rendering the latch mechanism operative or inoperative from the outside. IVhen on the inside of the door, it is possible to render the latch mechanism inoperative but not operative as to the outside.

In my patent of Nov. 28th, 1905, No.

805,687 is shown a keyless lock which can berendered operative or inoperative as to either side from either side of the door. The latch mechanism, however, is always locked or unlocked as to both sides of the door at any time. In other words, the latch mechanism cannot be independently operated on either side of the door.

In this application, I have shown a keyless lock, operative at all times from the inside of the door, provided with means operable from the outside of the door for rendering the latch mechanism operative or inoperative from that side as desired, and means operable from the inside for rendering the latch mechanism not only inoperative but also operative from the outside. I pause here to remark that when I refer to the insideH or outside of the door either in the specification or claims, I do not mean to use an expression of limitation, but adopt these Words merely for convenience in phraseology.

In the prior locks referred te, I employed for' the ends sought a collar with a labyrinth of grooves, and a pin engaging therein, the collar and pin being relatively movable. I have found it more convenient in practice to use a disk than a collar, and this application shows the specific means by which I adapt the disk to my keyless lock. Again, in these prior locks, the aim was to connect the parts of a two part spindle, one part of which was in permanent engagement with the latch mechanism, or to move some member which connected the spindle direct to the same.

This has proved unnecessary, as I find it as satisfactory in practice to utilize the combination member itself, as the collar or disk, to actuate the latch mechanism through suitable connections. For determiningthe relative movement of the collar and pin in these former locks, I employed means located outside of the casing of the lock. In this instance, I use the combination member to unravel its own labyrinth to the initiated,-- that is, to indicate through the sense of touch the passage of the pin through its labyrinth. of grooves.

In attaining the above general ends, I have made specific improvements which will appear as the speci'lication proceeds.

The accompanying drawings illustrate my invention, and I have used like numerals to designate like parts in the several views. Any mechanic skilled in this art, can readily suggest rearrangement or di'lferent construction of parts, and I therefore do not limit myself to the specific arrangement or structures shown. The spirit of my invention will be limited only by the claims.

In the drawings: Figure 1 is a longitudinal sectional view taken on the line 1 1 of Fig. 2. Fig. 2 is a sectional view taken on line 2-2 of Fig. 1. For convenience, in showing its relation to the other parts, the disk, which is in front, is shown in dotted lines.A Fig. 3 is a view similar to Fig. 2, looking from the other side of the door with the latch withdrawn. Fig. 4l is a plan view showing the disk with its labyrinth of grooves and its edges indented. Fig. 5 is a detail view partly in section showing the inside knob and connections. Fig, 6 is al detail end view of the knurl piece shown in Fig. 5 in cross section.

In the drawings are shown my lock arranged in the stile l of the door. The latch mechanism is contained in the casing 2 provided with the usual face plate 3 through an aperture 4 in which the latch bolt 5 operates.

The latch mechanismis here shown .in conventional form and consfsts essentially of the yoke 6 attached to the latch bolt and connected to the

latch arms

7 and 8 moving on l the guides 9 and 10 and provided at their rear l ends with the bent portions 1.1 and 12 respecl tively. The

springs

13 and 14 act on the i yoke to keep the bolt thrust outwardly or i normally in its locked position. The roll back 15 engages with the bent portions of the latch arms in a well known manner. l Properly secured in position by the es- IOO cutcheon plates 16 and 17 is a two part spindle, the ends of which are adapted to engage with each other. The outer spindle member is designated by the number 18, the inner spindle member by 19, and the

knobs

20 and 21 serve to Ioperate the respective spindle members. As previously stated, l use the terms inside and outside for convenience only, since the parts could of course be reversed and the spindle members applied to the opposite side of the door from that shown in the drawings.

The inner spindle member is at all times in operative relation to the latch mechanism by means of the key 22 formed on its circumference and in permanent engagement with the keyway 23 formed in the collar extension 24 of the roll back.

The outer spindle member is kept in position by means of the lugs 25 and at its inner end is chambered at 26, the walls of the chambered portion 26 being angular in shape to engage with an angular recess formed in the movable member 27, here shown as a disk and whose function will now be described.

l have aimed to supply for the outer spindle member means entirely independent of the inner spindle member adapted to bring the outer spindle member into or out of operative relation to the latch mechanism. lVhile this may be accomplished in various ways, l have here attained my purpose by providing a movable member and means whereby the movable member is capable of actuating the latch mechanism through proper connecting mechanism at a predetermined point in its movement. The movable member is shown in the form of a disk having its face provided with a labyrinth of grooves 2S and the connecting mechanism is preferably in the form of a spring link 29 pivoted to an arm 30 of the roll back. On the side of the link toward the grooves is a pin 30ZL adapted to engage with the grooves and to be guided through them by the movement of the disk until the latter is capable of acting upon the pin to actuate the latch mechanism. To enable the latch mechanism to be operated by the rotation of the disk, l provide yin the grooves a shoulder 31 to which the pin of the link is led when the disk is rotated or turned a variable predetermined number of times and a variable predetermined distance in opposite directions. As will be readily understood from an inspection of Fig. 3, when the pin is in engagement with this shoulder, the further movement of the disk acts on the pin and link to actuate the roll back and thereby withdraw the latch bolt.

It is highly desirable to so form the grooves that the pin will be prevented from taking the right course in the grooves when the combination has been improperly operated. Means for accomplishing this result may take various forms. l have here formed in the grooves inclines 33 and so fashioned the grooves on the faceof the disk that they all lead the pin, when the combination is improperly operated, into the groove 34 in which groove it is impossible for the disk and connections to operate the latch mechanism. To counteract any tendency of the inclines of the grooves to throw the pin out from the grooves, l have provided on the opposite side of the link, aprojection 35 contacting with the casing and thereby 1keeping the pin securely in the grooves as it passes through them` -lt is further necessary, when the pin comes into engagement with the shoulder in the grooves and the rotation of the disk acts upon it to withdraw'the latch mechanism, that means be provided for keeping the pin securely against the shoulder. Therefore, l have provided on the casing, a lug 36 onto which the projection on the link slides when it reaches the proper point, thereby holding the pin up to its work against the shoulder.

TWhen the pin of the link is in engagement with the shoulder in the grooves and the latch mechanism therefore operable by the rotation of the disk, means should beprovided readily throwing the pin out of engagement with the shoulder in order to make the latch mechanism inoperative as to the outside. For this purpose l have formed on the casing a cam 37 which will move the pin along the face of the shoulder when an eXtra pressure is exerted on the disk until the pin slips by the corner of the shoulder and through the action of the latch springs is swept through the grooveV 38 into the groove 34.

The pin, in passing out of engagement with the shoulder, must impart an eXtra inward motion to the latch bolt equal to the longitudinal movement of the pin, and provision must therefore be made to retract the latch bolt such necessary distance within the face plate. The pin, as it slips off the high portion of the tapers in the grooves has a tendency to produce a slight click sufficient to enable picking of the lock with the aid of a stethoscope. l therefore provide a safety means in the shape of a duplicate spring link, pin and projection numbered 39, 42 and 43 respectively, the link being pivoted at to post 4l formed on the casing. rlhis arrangement is a duplicate of the active link 29 and pin 30, and as it travels over the same passage or tapers, will produce the same click and might be called a blind pin or misleader as its only mission is to produce a similar sound to the active pin so that if it is attempted to pick the lock by sound, it will mislead the operator.

ln my prior inventions referred to in the lirst part of the specification, l have provided means outside of the casing of the lock for ascertaining the proper operation of the combination,-that is, the passage of the pin IOO IIO

through the grooves to such a point that the latch mechanism. becomes operative. I have here done away with this auxiliary index or guide, and employ the combination member itself to indicate to the initiated the proper course of the pin through the grooves. This is accomplished by forming in the edge of the disk a series of indents 44 corresponding to the divisions of the labyrinth of grooves. A pawl 45 is adapted to engage with these indents informing the operator by the sense of touch when it has engaged with the same. Means should be provided for forcing the pawl into engagement with the indents as they present themselves. The means which I prefer are shown in Fig. 3 where I have mounted the pawl on the post 46 formed in the casing and provided the pawl with the lever 47 adapted to throw the pawl into the indents. A spring should be provided for actuating the lever to throw the pawl into the indents. In this case I have utilized the latch springs for this purpose as will be understood from an inspection of Fig. 3.

It may be found desirable to bring the spindle members into engagement and to keep them united for the purpose of using the lock as a day latch. Furthermore, it may be desired when on the inside of the door to render the latch mechanism operative from the outside of the door as well as inoperative. That is, assuming the outer spindle member to be out of operative relation to the latch mechanism, it may be found desirable when on the inside of the door, to render the latch mechanism operative or inoperative from the outside without moving the combination member. To that end, the two part spindle has its ends adapted to engage with each other, and means are provided for holding the parts of the spindle normally out of engagement, while other means arev adapted to hold them united when the ends are brought into engagement. The engagement of the parts of the spindle is attained by forming a recess 48 in the inner end of the outer spindle, While in a recessed. portion 49 of the inner spindle part and seated on the spring 5() therein is the member 5].. Both the recess on the outer spindle and thelast mentioned member will of course preferably be angular in shape. The spring 50 serves to throw the member quickly into engagement with the recess when the latter and the member are in alinement. Acting against the inside knob to keep the spindle parts normally out of engagement, is the spring l52, here shown seated on the knurl piece 53. The latter is provided on its inner end with the chambered recess in which is formed the groove 55 and extending through the inner spindle member and resting in said groove when the spindle parts are 'out of engagement is the pin 56.

Vhen it is desired to unite the spindle parts, the inner knob is pushed in against the action of spring 52 and the knurl piece is turned to keep the knob in its inward position. The member 51 may not be in alinement with recess 48 at the time the inner knob is pushed in, thus forcing it into the inner spindle and causing a compression on spring 50 and this s ring will then snap it into engagement with tlie recess when the alinement is made; that is, immediately after rotating either knob a short distance. Key 22 is in slot 66 provided in member 5l so as to limit movement of the member and keep it out of engagement with recess 48 when the inner knob is in its outward position.

In pushing the knob 21 inward, the pin 56 is forced from the groove 55 in the knurl piece, and by turning the latter the pin rests on the shoulders 57 on each side of the groove and the spindle parts are thereby held in engagement with the latch mechanism which is then operative from the outside of the door through the inner spindle member, whose key is always in engagement with the keyway of the roll back. W'hen, now, it is desired to throw the outer spindle out of operative relation to the latch mechanism, the knurl piece is turned 'until the groove comes under the pin 56 when the action of the spring 52 will force the member 5l out of engagement with the recess 48. If the combination member has, during this process of uniting and disuniting the spindle members, been out of operative relation to the latch mechanism, the latter will then be left inoperative from the outside except by manipulating the combination.

The operation of the lock is as follows: Assuming the latch mechanism inoperative from the outside, the

indexes

58 and 59 on the knob 2() and escutcheon 1.7 respectively, are brought into alinement when the pin will be located at 60 in the labyrinth of grooves. Then by rotating the disk in opposite directions, the pin is guided through the grooves to the shoulder when the further rotation of the disk acts on the pin to retract the bolt and the lock is open from the outside. Then it is desired toloek the door from the outside, the pin may be returned through the labyrinth to the groove 34; or the disk may be furtherrotated., the cam 37 pushing the pin over the shoulder when the latch spring will cause it to go through the groove 3S to the groove 34 thus throwing it out of connection with the latch mechanism. Then it is desired to have the door open at all times, as for use in the daytime, the bolt is converted into a day latch in the manner previously described. The grooves of the disk can. be varied either in length or number or divisions, the combination. thereby being changeable as desired. In this case I have shown a disk having its grooves formed into twelve divisions as indicated by the notches on the disk best seen in Figs. 3 and 4 and the combi- IOO lIO

nation is 3, 9, 3. e. the pin being at the starting point is led through the grooves to 6l, where, if the disk be turned too far, the pin slips over the tapered portion 62 and passes into the groove 34, it being impossible to return it to 61 without bringing'it back to the starting point. From 6l the pin is moved to 63, then to 64, when the motion being reversed, the pin is brought to the shoulder at 65 and the latch mechanism is operative tromthe outside At each point where the direction of rotation should be changed, the pin is prevented by the inclines from taking the right course if moved too far, and the combination therefore improperlyY operated. The combination of grooves can of course be changed and the disk can therefore be move d a variable predetermined number ot times and a variable predetermined distance in opposite directions to bring the pin to the shoulder. Of course cams having different combinations can be readily substituted. The rst number of the combination can be changed by removing the outer knob with the spindle and replacing it, merelj,T changing its position in relation to the angular hole in the combination disk. In case the combination is on, it can be thrown out from the inside by pressing the inner knob and spindle into connection with the outer one and upon rotating it, the pin will be forced out of connection with the latch mechanism, as previously described.

It will be seen 'from an inspection ot Fig. l that the passages 62, 62a and b constitute misleading` passages, whereby when the cam disk is improperlyv operated in either direction the link or other member will be caused toI take a course which will le ad it to the starting groove Se in less than one revolution or the disk without reversing the motion.
