- This invention relates to permutation door locks.
- One object is to provide a combination lock embodying such characteristics that the door cannot be opened from the outside unless the manipulator knows the combination, and to provide further means whereby even if the combination is known the manipulator cannot effect unlocking of the door if it be desired to guard against opening of the door from the outside.
- Another object resides in the provision of a comparatively simple, inexpensive, durable and efficient lock of the nature stated, embodying among other characteristics such an arrangement of parts that the lock may be readily assembled and if desired quickly reversed for use either as a right or lefthand door look.
- a still further object resides in the provision of a lock having means whereby the condition of the lock for operating purposes may be ascertained whether in such condition for manipulation by means of elements having pricking engagement or other contact with the manipulators hand.

- Fig. 3 is a vertical longitudinal sectional view through the inner casing.
- Pg. 4; is a vertical cross sectional view through the outer casing.
- Fig. 5 is a detail face view of one of the rotatable combination members of the outer casing.
- Fig. 6 is a face view of the inner casing.
- Fig. 7 is a front face view of the outer casing.
- the reference character 10 indicates the door while the character 11 indicates a casing disposed on the outside of the door, there being a sectional casing on the inside of the door consisting of the main part 12 and the hinged section 13 hinged at 14 and provided with a knob 15 journaled through the section 13 and at its inner end provided with a latch 16 adapted to be turned into engagement with the underface of the top wall of the main part 12 of the inner casing, the purpose of form ing the inner casing in sections being so that access may be had thereto and particularly to reverse the position of the locking lever 17 pivoted at 18 in the inner casing for a purpose presently explained.
- a spindle 19' on the outer end of which slides a device consisting of a sleeve 21 having a knob 20 and at its inner end carrying a plate 22 provided with a finger 23.
- the plate 22 is bodily movable with the sleeve 21 on the spindle with the finger 28 of the plate working through an opening formed in the ratchet wheel or other rotatable member 25 fixedly secured on the spindle 19 in spaced relation to plate 22, so that the finger 23 may have cooperative engagement with the lugs 26 and 27 of the plates 28 and 29 clamped on the telescoping sleeves 30 and 31 for a purpose presently explained.
- the plates 28 and 29 are secured on the ratchet wheels or other rotatable members 32 and 33, respectively, and when the plates 28 and 29 are revolved with their respective sleeves 30 and 31 by reason of the finger 23 being brought into engagement with the lugs 26 and 27 of the plates 28 and 29 backward movement of said wheels and plates is prevented by virtue of the spring pawls 34 and engaging said ratchet wheels 32 and 38, there being a spring pawl 36 secured to the outer casing and adapted to engage the large ratchet wheel 25 to effect operation of the indicator pin 48.
- the character 37 indicates a spring supporting member secured within the outer casing and having its free end arranged in the path of movement of the finger 23.
- an indicator pin 38 which operates through the opening 39 in the top of the outer casing 11. The purpose of this indicator pin 38 is to indicate to the manipulator of the look when he has brought both wheels 32 and 33 into position for such operation as will enable the door to be unlocked.
- the manipulator will force the sleeve 21 in-- wardly as far as it will go the finger 23 of the plate 22 will take up both wheels 32 and 33 because the finger will bridge both lugs 26 and 27 of the plates 28 and 29 on the ratchet wheels 32 and 33, respectively, and then by revolving the plate 22, the wheels 32 and 33 will be turned, and on each revolution of the plate 22 the finger 23 will engage the yieldable support 37 and cause consequent reciprocating movement of the indicator pin 38.
- the pointed end 38 of the indicator pin with the manipulators finger, which latter he holds over the opening 39, he will know that by two engagements of the indicator pin 38 with his finger that all of the wheels are in condition for such operation as will effect an unlocking of the door.
- a disk 40 On the inner end of the sleeve 30 is a disk 40 while on the inner end of the sleeve 31 is a disk 41, there being a disk 42 fixed on the spindle 19, said disks 40, 41 and 42 being confined within the inner casing 1213.
- the character 44 indicates the bolt of the lock which is adapted to operate through openings 45 and 46, at opposite ends of the inner casing 12 and as shown in Fig. 3 the bolt is projecting through the opening 46 and held against inward movement by the tail-piece 47 of the locking lever 17. As will be explained hereinafter the bolt 44 may have movement through the opening 45, depending upon whether the lock is to be used as a right or a left-hand latch.
- the manipulator desires to open the door, he forces the sleeve 21 inwardly on the shaft 19 as far as possible.
- This movement of the sleeve 21 positions the finger 23 carried by the plate 22 so that it may engage the lugs 26 and 27 of the plates 28 and 29 on the wheels 32 and 33, respectively.
- the manipulator places one of his fingers or one of his hands over the hole 39 in the casing 11 and with his other hand grasps the knob 20 and turns the shaft 19 to the right until he gets two impressions from the indicator pin 38, this indicator 38 being reciprocated by reason of the yieldable element 37 being engaged twice by the pin 23 on the plate 22 of the sleeve 21.
- the manipulator then knows that the wheels 32 and 33 are in proper position for operation to unlock the lock.
- the manipulator then places his hand or finger over the hole 49 in the casing 11 and with his other hand turns the knob 20 to the right until he gets six impressions from the indicator 48 which is reciprocated by virtue of its connection with the yield able element 36 which operates over the teeth of the wheel 25.
- the manipulator in getting these six impressions from the inclicator pin 48 rotates all of the wheels 25, 32, 33, 40, 41 and 42 together because the pin 23 carried by the plate 22 is engaged with the wheel 25 through the aperture therein and is in engagement with the lugs 26 and 27 of the wheels 32 and 33 and because the wheels 41 and/4O being respectively on the same sleeves as are the wheels 32 and 33 with the wheel 42 on the shaft 19 on which the wheel 25 .is secured.
- all the wheels are rotated together when the pin 23 is in engagement with the lug 27 of the plate 29 on the wheel 33 and the knob 20 has been turned to the right until the manipulator has obtained six impressions from the indicator 48.
- the wheel 41 is also properly positioned so that its notch 50 may take the part 51 of the lever 17 when the last point in the combination has been efiected.
- the manipulator pulls outwardly on the knob 20 to pull the sleeve 21 and the finger 23 on the plate 22 away from the lug 27 on the wheel 33.
- the manipulator now grasps the knob 20 and turns it to the right until he gets one more impression through the hole 49 from the indicator pin 48.
- the manipulator knows that by reason of the pin 23 on the plate 22 passing through the aperture in the wheel 25 and being in engagement with the lug 26 on the plate 28 carried by the wheel 32 that the latter and the wheel 40 have been properly positioned to effect the second step in the combination with the notch 50 of the wheel 40 in position to take the part 51 of the lever 17 when the last step in the combination has been effected. Now that the second step in the combination has been effected, the manipulator grasps the knob 20 and on an outward pull of the same releases the pin 23 of the plate 22 from engagement with the lug 26 on the plate 28 carried by the wheel 32.
- the manipulator receives this last impres sion from the indicator 48 through the hole 49 he thereby knows that he has effected such manipulation of the wheels as to per mit the lever17 tobe moved onrits pivot 18 to throw the part 51 of the lever 17 into the notches 50 of the wheels 40, 41 and 42 and thereby permit the tail piece 47 of the lever 17 to be lifted from behind the latch 44 which latter may now be moved inwardly of the casing by manipulation of the shifting lever 52 pivoted at 53 in the slot 54 of the casing 11 and also extending through the slot 55 in the door 10 to engage the notch in the slidable bolt 44.
- the indicator pin 48 is reciprocated all the time with the pro-per combinations being effected to unlock the door and that the indicator pin 38 is intended only for the purpose of placing the wheels 32 and 33 in such position as to start operation of the lock to effect the combination so that the door may be opened.
- the indicator pin 38 gives two impressions while the indicator pin 48 gives the remaining impressions.
- the sectional casing may then be closed and the operation heretofore described for effecting a locking and unlocking repeated and in order that the locking lever 17 may be operated so as to disengage its tail-piece 47 from engagement with the bolt 44
- the looking lever pivot 18 is preferably in the form of a rotatable shaft on which the lever 17 is fixed, and this shaft is indicated at 57 and at its outer end provided with a knob 58 so that it may be rotated in its bearings in the outer casing and in the door 10 as shown clearly in Fig. 2.
- a pivoted latch 58 on the inner side of the sectional casing 12-13.
- This latch 58 may be thrown in either direction on its pivot to engage the lug 59 operating in the slot 60 so that whether the lock is for the right or left-- hand side of a door, the bolt 44 cannot be opened, as may be seen particularly by reference to Fig. 6.
- t-heratchet wheels 32 and 33 like the ratchet 25, are rotatable members and that the ratchet wheels 32 and 33 rotate their respective sleeves so as to correspondingly rotate the disks 40 and 41 at the opposite ends of their sleeves.
- the ratchet wheels 32 and 33 are what may be termed rotatable members having, by virtue of the plates 28 and 29,
- ratchet wheels 32 and 33 may be regarded as rotatable members provided with projecting portions designed for engagement by the aforesaid pin 23 upon rotation of the knob 20, sleeve 21 and plate 22.
- this sectional casing gives access to the disks 40, 41 and 42 so as to change them to any combina tion desired.
- this sectional casing if a person should be out late at night, and a person on the inside wished to retire before the absent one came back, and especially if that absent one did not understand the combination, it would simply be necessary to raise the hinged section 13 and push the bolt 44 into its proper locking position and the lever 17 so that its part 51 would enter the notches 50 in the disks 40, 41 and 42, in which event, the absent one upon his return could readily shift the bolt to unlocked position from the outside.

Specification of Letters Patent.
Patented July 22, 1913.
Application filed June 1'7, 1911. Serial No. 633,876.
To all whom it may concern Be it known that I, SAMUEL THOMAS WoLr, citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented cer tain new and useful Improvements in Permutation Door-Locks, of which the following is a specification.
This invention relates to permutation door locks.
One object is to provide a combination lock embodying such characteristics that the door cannot be opened from the outside unless the manipulator knows the combination, and to provide further means whereby even if the combination is known the manipulator cannot effect unlocking of the door if it be desired to guard against opening of the door from the outside.
Another object resides in the provision of a comparatively simple, inexpensive, durable and efficient lock of the nature stated, embodying among other characteristics such an arrangement of parts that the lock may be readily assembled and if desired quickly reversed for use either as a right or lefthand door look.
A still further object resides in the provision of a lock having means whereby the condition of the lock for operating purposes may be ascertained whether in such condition for manipulation by means of elements having pricking engagement or other contact with the manipulators hand.
With the above and other objects in View, the present invention consists in the construction and arrangement of parts herein after more fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings :Figure 1 is a horizontal sectional view of the invention. Fig. 2 is a vertical cross sectional view of the invention. Fig. 3 is a vertical longitudinal sectional view through the inner casing. Pg. 4; is a vertical cross sectional view through the outer casing. Fig. 5 is a detail face view of one of the rotatable combination members of the outer casing. Fig. 6 is a face view of the inner casing. Fig. 7 is a front face view of the outer casing.
Referring now more particularly to the accompanying drawings the reference character 10 indicates the door while the character 11 indicates a casing disposed on the outside of the door, there being a sectional casing on the inside of the door consisting of the main part 12 and the hinged section 13 hinged at 14 and provided with a knob 15 journaled through the section 13 and at its inner end provided with a latch 16 adapted to be turned into engagement with the underface of the top wall of the main part 12 of the inner casing, the purpose of form ing the inner casing in sections being so that access may be had thereto and particularly to reverse the position of the locking lever 17 pivoted at 18 in the inner casing for a purpose presently explained.
J ournaled through the door and casings is a spindle 19' on the outer end of which slides a device consisting of a sleeve 21 having a knob 20 and at its inner end carrying a plate 22 provided with a finger 23. The plate 22 is bodily movable with the sleeve 21 on the spindle with the finger 28 of the plate working through an opening formed in the ratchet wheel or other rotatable member 25 fixedly secured on the spindle 19 in spaced relation to plate 22, so that the finger 23 may have cooperative engagement with the lugs 26 and 27 of the plates 28 and 29 clamped on the telescoping sleeves 30 and 31 for a purpose presently explained. The plates 28 and 29 are secured on the ratchet wheels or other rotatable members 32 and 33, respectively, and when the plates 28 and 29 are revolved with their respective sleeves 30 and 31 by reason of the finger 23 being brought into engagement with the lugs 26 and 27 of the plates 28 and 29 backward movement of said wheels and plates is prevented by virtue of the spring pawls 34 and engaging said ratchet wheels 32 and 38, there being a spring pawl 36 secured to the outer casing and adapted to engage the large ratchet wheel 25 to effect operation of the indicator pin 48.
The character 37 indicates a spring supporting member secured within the outer casing and having its free end arranged in the path of movement of the finger 23.
Mounted on the spring member 37 is an indicator pin 38 which operates through the opening 39 in the top of the outer casing 11. The purpose of this indicator pin 38 is to indicate to the manipulator of the look when he has brought both wheels 32 and 33 into position for such operation as will enable the door to be unlocked. For instance, it the manipulator will force the sleeve 21 in-- wardly as far as it will go the finger 23 of the plate 22 will take up both wheels 32 and 33 because the finger will bridge both lugs 26 and 27 of the plates 28 and 29 on the ratchet wheels 32 and 33, respectively, and then by revolving the plate 22, the wheels 32 and 33 will be turned, and on each revolution of the plate 22 the finger 23 will engage the yieldable support 37 and cause consequent reciprocating movement of the indicator pin 38. By engagement of the pointed end 38 of the indicator pin with the manipulators finger, which latter he holds over the opening 39, he will know that by two engagements of the indicator pin 38 with his finger that all of the wheels are in condition for such operation as will effect an unlocking of the door.
On the inner end of the sleeve 30 is a disk 40 while on the inner end of the sleeve 31 is a disk 41, there being a disk 42 fixed on the spindle 19, said disks 40, 41 and 42 being confined within the inner casing 1213.
The character 44 indicates the bolt of the lock which is adapted to operate through openings 45 and 46, at opposite ends of the inner casing 12 and as shown in Fig. 3 the bolt is projecting through the opening 46 and held against inward movement by the tail-piece 47 of the locking lever 17. As will be explained hereinafter the bolt 44 may have movement through the opening 45, depending upon whether the lock is to be used as a right or a left-hand latch.
If the combination of the lock be 678 and it the manipulator desires to open the door, he forces the sleeve 21 inwardly on the shaft 19 as far as possible. This movement of the sleeve 21 positions the finger 23 carried by the plate 22 so that it may engage the lugs 26 and 27 of the plates 28 and 29 on the wheels 32 and 33, respectively. The manipulator then places one of his fingers or one of his hands over the hole 39 in the casing 11 and with his other hand grasps the knob 20 and turns the shaft 19 to the right until he gets two impressions from the indicator pin 38, this indicator 38 being reciprocated by reason of the yieldable element 37 being engaged twice by the pin 23 on the plate 22 of the sleeve 21. The manipulator then knows that the wheels 32 and 33 are in proper position for operation to unlock the lock. The manipulator then places his hand or finger over the hole 49 in the casing 11 and with his other hand turns the knob 20 to the right until he gets six impressions from the indicator 48 which is reciprocated by virtue of its connection with the yield able element 36 which operates over the teeth of the wheel 25. The manipulator in getting these six impressions from the inclicator pin 48 rotates all of the wheels 25, 32, 33, 40, 41 and 42 together because the pin 23 carried by the plate 22 is engaged with the wheel 25 through the aperture therein and is in engagement with the lugs 26 and 27 of the wheels 32 and 33 and because the wheels 41 and/4O being respectively on the same sleeves as are the wheels 32 and 33 with the wheel 42 on the shaft 19 on which the wheel 25 .is secured. Thus all the wheels are rotated together when the pin 23 is in engagement with the lug 27 of the plate 29 on the wheel 33 and the knob 20 has been turned to the right until the manipulator has obtained six impressions from the indicator 48. hen the wheel 33 has been positioned to effect one point in the combination the wheel 41 is also properly positioned so that its notch 50 may take the part 51 of the lever 17 when the last point in the combination has been efiected. After effecting this first point in the combination, the manipulator then pulls outwardly on the knob 20 to pull the sleeve 21 and the finger 23 on the plate 22 away from the lug 27 on the wheel 33. The manipulator now grasps the knob 20 and turns it to the right until he gets one more impression through the hole 49 from the indicator pin 48. When this additional impression has been received, the manipulator knows that by reason of the pin 23 on the plate 22 passing through the aperture in the wheel 25 and being in engagement with the lug 26 on the plate 28 carried by the wheel 32 that the latter and the wheel 40 have been properly positioned to effect the second step in the combination with the notch 50 of the wheel 40 in position to take the part 51 of the lever 17 when the last step in the combination has been effected. Now that the second step in the combination has been effected, the manipulator grasps the knob 20 and on an outward pull of the same releases the pin 23 of the plate 22 from engagement with the lug 26 on the plate 28 carried by the wheel 32. By then placing his hand over the hole 49 and turning the knob 20 to the right he rotates the wheel 25 until he gets one impression from the indicator 48. When the wheel has, been given this additional turn, the wheels 32, 33, 41 and 40 are not turned but the wheel 42 is turned when the wheel 25 is given the last turn because the wheels and 25 are fixed to the shaft 19. lVhen the manipulator receives this last impres sion from the indicator 48 through the hole 49 he thereby knows that he has effected such manipulation of the wheels as to per mit the lever17 tobe moved onrits pivot 18 to throw the part 51 of the lever 17 into the notches 50 of the wheels 40, 41 and 42 and thereby permit the tail piece 47 of the lever 17 to be lifted from behind the latch 44 which latter may now be moved inwardly of the casing by manipulation of the shifting lever 52 pivoted at 53 in the slot 54 of the casing 11 and also extending through the slot 55 in the door 10 to engage the notch in the slidable bolt 44. It will thus be seen that the indicator pin 48 is reciprocated all the time with the pro-per combinations being effected to unlock the door and that the indicator pin 38 is intended only for the purpose of placing the wheels 32 and 33 in such position as to start operation of the lock to effect the combination so that the door may be opened. In other words, the indicator pin 38 gives two impressions while the indicator pin 48 gives the remaining impressions.
Assuming that the lock described is used as a right-hand door latch and it is desired to use it as a left-hand door latch it is simply necessary to unlock the latch 16 of the inner casing 1213 and shift the part 13 on its pivot 14 when access may be had to the sectional or inner casing and permit the looking lever 17 to be reversed so that its tailpiece 47 may have cooperative engagement with the right-hand end of the bolt 44. The sectional casing may then be closed and the operation heretofore described for effecting a locking and unlocking repeated and in order that the locking lever 17 may be operated so as to disengage its tail-piece 47 from engagement with the bolt 44 the looking lever pivot 18 is preferably in the form of a rotatable shaft on which the lever 17 is fixed, and this shaft is indicated at 57 and at its outer end provided with a knob 58 so that it may be rotated in its bearings in the outer casing and in the door 10 as shown clearly in Fig. 2.
In the event that it be desired that the lock be not manipulated from the outside to open the door there is preferably provided a pivoted latch 58 on the inner side of the sectional casing 12-13. This latch 58 may be thrown in either direction on its pivot to engage the lug 59 operating in the slot 60 so that whether the lock is for the right or left-- hand side of a door, the bolt 44 cannot be opened, as may be seen particularly by reference to Fig. 6. I
From the foregoing, it will be understood that t- heratchet wheels 32 and 33, like the ratchet 25, are rotatable members and that the ratchet wheels 32 and 33 rotate their respective sleeves so as to correspondingly rotate the disks 40 and 41 at the opposite ends of their sleeves. The ratchet wheels 32 and 33 are what may be termed rotatable members having, by virtue of the plates 28 and 29,
By having the inner casing composed of sections, it has the advantages other than to permit access to the interior thereof so that the parts may be reversed, in that this sectional casing gives access to the disks 40, 41 and 42 so as to change them to any combina tion desired. Moreover, by virtue of this sectional casing, if a person should be out late at night, and a person on the inside wished to retire before the absent one came back, and especially if that absent one did not understand the combination, it would simply be necessary to raise the hinged section 13 and push the bolt 44 into its proper locking position and the lever 17 so that its part 51 would enter the notches 50 in the disks 40, 41 and 42, in which event, the absent one upon his return could readily shift the bolt to unlocked position from the outside. Suppose a member of ones family should be out late and those on the inside wished to retire, and assuming that those on the outside knew the combination, those on the inside could simply raise the hinged section 13 to the casing 12 and push the bolt 44 forward, turn the lever 17 down, and then turn the disks 40, 41 and 42 so that the notches 50 cannot be entered by the part 51 of the lever 17. The lock will then be locked just the same as one would look it from the outside and those on the inside are securely locked in while those on the outside may unlock the door, without disturbing those on the inside.
