Specification of Letters Patent.

Patented Sept. 2*?, 1919.

Application filed November' 27, 1909. Serial No. 530,190.

To all 'whom it may concern:

Be it known that l, AUGUST hunne, a citizen of the United States, residingI at New Britain, county of Hartford, State of Connecticut, have invented cert-ain new and useful Improvements in Entrance-Boor Locks, of which the following is a full, clear, and exact description.

My invention relates to locks, and particularly to improved features of construction in that type of lock illustrated in the Phelps Patent No. 722,619, ot' March 10, 1903.

Tie object oit the present invention is to provide, in the type of lock referred to, certain improved. features of construction whereby the outside knob may be dogged in a unique manner against rotation (for the purpose of operating the latch mechanism) and whereby, even though said outer knob be dogged, entrance :trom the outside may still be elfected by means et a proper key.

The invention also comprehends in its construction apparatus for actuating a dead bolt from either the inside or outside ot a door at any time, said deadbolt being` actuated by the saine instrumentality as is employed for operating the latch mechanism from the outside ot the door when the outer knob is dogged, viz., a key.

rllh-e invention has great utility in connection with entrance doors, particularly entrance doors for public institutions and stores wherein the locks are subjected to much use.

ln the lock of the patent to .vhich l have above referred the (logging mechanism for the outer knob is controlled wholly by an exposed operating ring located so closely to the shell of the inside handle that it sometimes happens that a person passing from the inside to the outside of a door accidentally and unintentionally turns the dog operating ring` simultaneously with turning the inner knob, which act either dogs or releases the outer knob as the case may be. Obviously, if it has been the intention ot the owner of the lock to dog the outer knob so that entrance can not be had t'rom the outside without proper announcement or without. the use of a proper key, such intention would be defeated by the accidental manipuyPatent No. 834,994.

lation and releasing of the dog operating ring above referred to.

My present invention eliminates all danger or' accidental or unintentional operation of the dog actuator and dog. Not alone does the present invention accomplish this but it also prevents all mischievous tampering with the lock in such a way as to dog or release the outer knob as the case may be.

llfhese and other advantages will be apparent to the mechanic skilled in the art by a reading of the following description and an examination of the accompanying drawings, in which- Figure 1 is a plan view; Fig. 2 is in the main a section on the line a-rc of Fig. 1, certain parts being shown in elevation; Fig. 3 is an elevation of certain parts taken on the plane on the line jz/-Ii/ ot Fig. 2; Fig. 4f is a section on the plane of the line :1f-z of Fig. 2, certain parts being shown in elevation, and certain parts being omitted; Fig. 5 is a plan view ot' a detail (the central spindie) detached; Figs. 6, 7, 8, 9 and 10 are end views of other details; Fig. 11 is a fragmentary side view ot another detail, partly in section; Fig. 12 is a similar view of still another detail; Fig. 13 is a view of the outer side of the inner section of one ot the knobs; Fig. 14 is a side elevation of another detail; Fig. 15 is an end view or' another detail; Fig. 16 is an end view ot the detail shown in Fig. 14s; Fig. 17 is a side elevation of the forward end of the lock shown in Fig. 1.

For a detailed description of most ot the features ot construction employed. in the present lock, reference may be made to the Phelps patent above referred to, also Phelps As to such features as are described in said patents, l shall refer to the same herein in general terms only, devoting the detail description to such features of improvement as have been invented by me.

rlhe lock in its preferred form includes the main supporting traine 1, having the face plate 2 at its trout end and having` the knob supporting bearings 8 4 near its rear end.

5 is a. latch bolt.

6 is a dead bolt.

7 is an actuator for a latch dog, whereby when the door is closed the latch 5 can not be pushed back by the insertion of a thin blade or other appropriate instrument into the space, between the edge of a door (bearing said lock) and the door casing,-a method of unlawful entry commonly practiced.

In the' present instance 8 represents the inner knob and 9 the outer knob of the lock. These knobs are provided with inwardly projecting' shanks 8at and 9a respectively.

10-11 are independent roll backs both arranged to engage the yoke 12 of the latch bolt, whereby said latch bolt may be retracted by turning either knob, said roll backs being suitably connected with the shanks of said knobs 3-9 respectively, one suitable method of connecting said parts being disclosed in the patent rst above referred to. The roll back 11 is so mounted that when in one position it may turn freely with the shank of the knob 9 but when said roll back is in another position it engages in notches in the fixed frame of the lock, and hence can not be turned. Under such conditions it is plain that the shank 9a can not be turned and hence at such a time the outer knob 9 will be dogged This construction and operation is more fully disclosed in the earlier patents referred to.

50 is a single armed roll-back mounted upon an internal spindle 13 which is controlled by a suitable key which may be inserted in the outer end of either knob, both knobs having the usual pin-tumbler lock therein later referred to. The roll-back 50 is adapted to perform the single function of operating the dead bolt 6, the intermediate connecting mechanism between said dead bolt and said roll-back 50 being similar to that shown, described and claimed in Phelps Patent No. 722,619.

14k-15 are locks arranged to be carried by and within the knobs 9 8 respectively, said locks in this particular instance beingI of the pin-tumbler type. The plug end of each of these locks is of special formation, each being dierent, hence I will describe the same separately.

The inner end 14a of the plug of lock 14; (for the outer knob) has a central bore which rotates on the end of the spindle 13, the corners of the latter being rounded off somewhat to avoid undue wear. rEhe spindle 13 receives its support at one end in this plug. To provide a proper bearing, and to perform another function hereinafter more fully described, the plug of the lock 14 extends inwardly, as at lett, Fig. et. One side of this plug end 14eZL is cut away, as indicated at 11th, (Fig. 15) to afford a receiving space for a pin 16 projecting laterally from an adjacent part of the spindle 13.

The plug of the lock 15 has a tubular eX- tension 15:l but in this instance said tubular extension is in the form of a sleeve rotatably mounted upon the solid end of the plug, said solid part being shown at 17 (F ig. la).

17EL is a pin projecting laterally from the solid inner end 17 of the plug of lock 15, said pin end standing in a slot arranged transversely in the wall of the sleeve extension 152L so that said sleeve extension may have a limited amount of rotary movement relatively to the solid part 17 of the plug, and vice versa. The outer end of the sleeve extension 15a of the plug has a specially formed spiral cam, which begins approximately at the point indicated at 13, and terminates at the point indicated at 19. As a matter of fact the low part of said spiral groove terminates or communicates with a back-set notch, as clearly shown in the drawings, the function of which will later be seen. A laterally projecting pin 20 t) on spindle 13 bears against the wall of the spiral cam at the inner end of the sleeve extension 15a, the adjacent end of the spindle 13 being supported in the round bore of said sleeve extension in a manner similar to the support for the opposite end of the spindle 13. 21 is a single armed roll-back, which lies adjacent to the roll-back 50 when the parts are assembled, the single arm of said roll-back 21 performing the function of coupling the key-actuated spindle 13 with the latch slide for the purpose of retracting the latch bolt by means of a key. This particular roll-back construction is described in more detail in the former Phelps Patent No. 722,619.

The spindle 13 has an intermediate round portion 13a and has a stop shoulder 13b at one side of said round portion. The shiftable roll-back 11 always stands adjacent to the rounded portion 13a, being prevented from moving to one side thereof by the stop shoulder 13b and to the other side by a friction held sleeve 22, which may be slipped over the spindle 13 from one end. One or both of the pins 16--20 may be made removable. The roll-backs 50 21 each have an opening so shaped that while the same may slide upon the spindle 13 neither of them can rotate independently thereof. The inner end of the tubular knob bearing 3 is notched at 23 to receive the shift-able rollback 11 when it is desired to dog the outer knob 9 against rotation.

241 is an expansion spring located between the inner end of the plug extension 141 and the friction sleeve 22, suitable washers being provided as shown, if desired, to aHord a proper support for the ends of said spring. The function of this spring 2;-1 is to gently press the spindle 13 to the right as viewed in F ig. 2 so as to hold the pin 2O against the spiral cam at the inner end of the sleeve extension 15a.

lll@ is an otlset on the outside of the plug' 1td while 14d is a stop pin on the inner wall ot the knob 9 in the path of movement ot the offset shoulder 14C, the purpose of said otlset and pin being to limit the rotation of the plug end 1sta so that it will not override any ot the parts. lt will be understood that the knob 8 is always tree to turn to withdraw the latch.

Uperation: lt will be understood that, like the previous locks referred to,the present construction may be employed in a similar manner in many respects. For example, the latch bolt 5 may be retracted by the turning ot either of the knobs 8 or 9 or by the turning of the spindle 13 by means ot a suitable key in the proper direction to cause the roll-back 21 to engage the latch slide. ln the present case, however, the key-controlled spindle may be rotated by a suitable key in such al manner as to advance or retract the dead bolt, a feature not possible with the spindle shown in the lock ot the patent previously referred to. ln the present instance, too, it is possible through the medium ot the same spindle to dog` and release the outer knob from the inside of the door to which the lock is applied. The construction is also such that no matter what function is to be pervtermed by the key-controlled spindle, it is possible at any time to impart the desired motion to the lock by the key and then withdraw the same. ln performing` these functions the operation is as lollows: Assuming` the parts are as shown in the drawings with the dead bolt withdrawn and both knobs tree to turn. lt it is desired simply to dog the outer knob, the operator has but to turn counter clockwise the sleeve extension 15EL by the insertion of a suitable key in the lock 15. By turning' this sleeve in a counter clockwise direction the spiral cam thereon causes the pin 2O and spindle 13 to move to the lett, as viewed in Fig. 2. One complete revolut-ion of the sleeve 15a accomplishes this shitting;r ot the spindle to a suthcient extent to move the roll-back 11 into the notches Q3 at the inner end of the stationary knob bearing' 3. yl`he key may then be withdrawn. This act ot' shitting' the spindle and rollback 11 dogs the outer knob 9 so that the saine can not be turned and the latch can not be retracted thereby. The insertion ot the key in the inner knob and a clockwise complete revolution will restore the parts to the original. position, the spring` 24 aiding` in this operation. lt at any time during;l the period when th-e outer knob is dogged it is desired to enter trom the outside, the holder of the suitable key inserts it in the lock in knob 9 and turns the same in a counter clockwise direction causing one side ot the clearance recess 14th to engage pin 16 on the spindle 13 so that a continued rotation ot the key (and plug ot lock 1s in the same direction will rotate spindle 13 so as to retract the latch through the medium ot the roll-back 21.` lt it is lesired to not only dog the outer knob, but also to advance the dead bolt G, this may be accomplished from the inside by inserting` a key and turning it as tirst described one complete revolution counter clockwise to tirst dog the outer knob; then, by continuing' this revolution the wall at the end ot' the aforesaid set-back notch will engage the pin 2O and turn the spindle in a direct-,ion to advance the dead bolt t3 through the medium ot rollback 50. A partial clockwise rotation ot the key will bring it back into proper position tor removal, leaving' the outer knob dogged and the dead bolt advanced. lt' one desires to enter trom the outsid-e under such conditions he has but to insert a suitable key in the lock in the outer knob 9 and turn it in a counter clockwise direction as betere, causing one side ot' the clearance notch lll-h' to en: gage pin 16, whereupon continued rotation imparts to the spindle corresponding rotation so that the dead bolt il will iirst be withdrawn by action of the roll-back 50. ,lontinucd rotation in the saine direction causes the retraction ot the latch slide (the out-er knob itself beingstill dogged) through the medium ot the roll-back Q1.

Assuming the parts are in the position shown in the drawings, and the user oit the lock simply wishes to go outside and lock the door from the outside by means et dead bolt 6, he has but to insert the key in the lock in the outer knob and turn it in a. clockwise direction, bringing' one side wall ot the notch 1lb into engagement with the pin 1G, turning' the spindle 1S 'thereby in the same direction until the dead bolt t3 is projected through the medium oit' the rollback 50. ly then reversing the direction ot rotation ot the key and bringing; it to its original position, said key maybe withdrawn.

To withdraw the dead bolt trom the outside (the outer knob not beingl dogged in this case) the key may be again inserted and turned in a counter clockwise direction until the opposite side et the notch vlelengages the pin 1G whereupon continued .rotation withdraws the dead bolt tln'ough the medium ot the same roll-back ltroin the foregoing it will be seen that all ot the functions necessary in any single entrance door lock are capable ot porterinance here and the moditied and atleed tean turcs ot' construction, which have been applied by me to the aforesaid well known Phelps locks, in no way impair or intortere with the action of the parts as provided in said Phelps locks. ln the present construction there is no possibility ot' unintentional, accidental or mischievous dog- AQing or undogging of the outer knob or locking or unlocking' of the door, since it can only be accomplished by one who has sutlicient authority to hold a proper key.
