Registering Time Lock.
I, EDWIN SANFORD PHELPS, Resident of Elizabeth, New Jersey, and doing
business at 74, Cortlandt Street, New York City, State of New York, United
States of America, and by occupation a Manufacturer of Time Locks, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement
-
My invention has reference to locks, applicable for stores or other business
places where it is desnable to register the times at which the door is closed and
opened, thus indicating at what hour or fraction of an hour the place of business
was closed and at what hour, or fraction of an hour, it was opened up for business,
or at what hour and fraction of an hour the door 18 unlocked and again locked
outside of business hours The lock is so arranged as to provide against mani-
pulation of the lock with the view of clandestinely entering the establishment
outside of business hours and concealing the fact, as this cannot be done without
making a record of the fact and indicating the time when any such attempt was
made
The construction of time lock according to this invention will now be described
with reference to the accompanying diawings.
Figure 118 a front elevation of the lock with its front casing removed and
with parts broken away;
Figure 2 is a fiont elevation with a portion of the bottom and of the top broken
away and certain parts omitted
Figure 3 is a side elevation of Figure 2,
Figure 4 is a part front elevation of the might check mechanism modified to
adapt it to a left hand lock, and
Figure 5 is a plan of a portion of the registering mechanism
1 designates the base or back plate which supports the mechanism and 2 a
section of the enclosing case 3 is the shading bolt which may be operated at
any time from inside the apartment by inserting the key into the hub 4 so as
to act upon the tumblers in the extension 5 and free the same so that the hub
may be turned When the hub is turned in one direction a protuberance 6 on
it engages the bai 7 and depresses a sliding dog 8 which is attached to 7 and
moves in a suitable recess in the bolt 3 so as to release a rack 9 at the top of the
dog from its engagement with rotatable studs 10, and thus leaves the sliding
bolt free to be moved in or out by the key After the protuberance 6 has de-
pressed the dog 8, an extension 11 on the hub 4 which works in a cam way
shown by dotted lines 12 bears against the dog and pushes it and the sliding bolt
out in the locking position. On turning the hub in the opposite duection the
extension 11 bears against the cam wav 12 un the opposite direction so as to draw
back the bolt and thus unlock the door In this backward movement of the hub
the protuberance 6 on the hub engages with the upper bai 7 which lifts the dog 8
into the position shewn in full lines in Figure 1 so as to bing the rack 9 again
into engagement with the studs 10, this raising of the dog takes place after the

page_text: bolt has been drawn in, and thus leaves the parts in position to be operated
from the outside of the door by rotation of the studs 10
The studs 10 project from a rotatable hub 13 which turns in a collar 14, and
this hub is connected in any suitable way with the rotatable portion of a flat key
tumbler lock which may be of the well known Yale type, the hub of which is
indicated at 15 in Figure 3, its details are not shewn as they are of well known
construction
the hub 13 is revolved by the tumbler lock the studs 10 bear against the tooth of
the rack 9 and move the bolt 3 so as to lock or unlock.
This hub 15 19 secured to the back plate 1 by screws 16
When
A frame 17 connected to the back plate 1 contains any suitable seven day
clock mechanism which is not shewn The wheel 18 seen in Figure 1 is that of
the clock spring barrel, and 19 is the winding stem From the face plate of the
frame 17 supported by studs 20 18 a plate 21 which carries the registering
mechanism Motion 18 transmitted to this mechanism from the toothed wheel 18
through a pinion 21 upon a shaft 22 which has at its outer end a wheel 23
gearing with a wheel 24 which may be termed the hour wheel as it makes one
revolution in twenty four hours This hour wheel 18 mounted on a stud 25
projecting from the face plate 21, having a sleeve 26 which turns on the stud 25
This sleeve carries a dial plate 27 in front of the hour wheel 24 and a pinion 28
behind the hour wheel, which is held on the sleeve 26 between the dial plate 27
and panion 28 by friction sufficient to cause the hour wheel and dial plate to turn
together and yet to permit the dial plate and the pinion 28 to turn independently
of the hour wheel Thus the dial plate can be adjusted and with it the snail 32,
hereinafter described, for moving the puncturing punch The pinion 28 transmits
motion to a pinion 29 which transmits motion to a pinion 30 which gears wath
a toothed wheel 31 having on it the snail 132 made in the form of an involute
of a circle Against the snail a spring 45 carries a stud on an arm 33 projecting
from a sleeve 34 that can turn upon a stud 35 and carnes at its outer end
(Figure 5) two plates 36 and 37 between which is situated the periphery of the
recording dial hereinafter described The plate 37 has a perforation through
which is projected the punch 38 This is attached to the spring plate 39 which
18 secured to the sleeve 34 so as to move in accord with the arm 33 and the
plates 36 and 37 The plate 37 serves as a guard for the recording dial so that
when the punch 38 perforates the dial and is retracted the dial is not drawn
out of position by the punch.
40 18 the recording dial which may be made of paper
It is mounted upon
the nave of the dial plate 27 and is held thereon by the spring fingers 41 extending
from a hub which fits upon the hub 42 of the dial plate, the pressure of the
fingers against the recording dial being regulated by a nut 43 screwed on
the hub 42 of the dial plate The recording dial has divisions representing the
seven days of the week formed by involute curved lines, each line representing
the twenty four hours of the day, so that one dial seives for one week, each
imvolute line representing one day of the week The involute lines are divided
by tiansveise unes into spaces representing the hours of the day, the space
between the hour divisions being divided by transverse lines indicating fractions
of an hour, for instance into six spaces each space representing ten minutes
The recording dial is marked with numerals indicating hours, these may be
arranged in two divisions each of twelve hours or they may run from one to
twenty four The dial plate has a pin 44 which enters a hole in the paper dial
fo as to insure the ready adjustment of the paper dial on the dial plate and to
prevent it from slipping The involute curves of the dial and the involute of
the snail are so related that while the snail makes one revolution the recording
dial makes seven revolutions, the snail thus travelling each day a distance de-
finitely proportioned to the length of the curve representing the day, so that the
snail cairies the punch from one curved line to the next as one day succeeds
another
The punch 38 is acted on by the arm 46 of a rock shaft 47 urged by a spring 48

page_text: The lower end of the rock shaft 47 has an aim 48" having its end preferably
formed with bevelled faces 49 and lying in the path of an arm 50 operated from
the outside tumbler lock This arm is preferably fixed by a set screw to one of
the pins 10 and has a knob 61 which engaged the bevelled surfaces of the arm 48°
on the rock shaft, when the bolt is locked and also when it is unlocked by a
key applied from the outside
When the bolt moves to lock the door the knob 51 on the arm 50 presses on
the arm 48 so as to turn the rock shaft 47 and throw its arm 46 against the
spring plate 39 which caures the punch and thus to puncture the recording
dial and indicate the time when the door was locked The spring 48 turns
back the rock shaft, when the arm 50 fiees the arm 48. In unlocking the same
operation takes place
The pointer 52 on the perforating spring am 39 serves as an index for the
proper adjustment of the paper dial upon the dial plate so that the dial and the
dial plate may be adjusted to proper position in accord with the day, the hour,
and fraction of the hour at the tume when the dial is placed, the register being
then made from that time onwards.
In order to prevent the lock from being so manipulated by quickly locking
and unlocking without any appreciable time between the two operations as to
make only a single perforation and leave the door unlocked, I employ what
may be termed a night check which ensures a second perforation in the dial
notwithstanding immediate unlocking after locking To do this I avail myself
of the slack which always more or less exists in the clock and other gearing as
follows A wheel 53 gearing with the hour wheel 24 gears also with a wheel 54
which 18 mounted upon a yoke or atm 55 pivotted on the axis of 53
The pivot
of 34 carries a disc 56 which preferably has a frictional surface of rubber and is
acted on by a cam 57 which may have a grooved periphery and which is upon
an axis 58 carrying a toothed wheel 59 with which gears a toothed wheel 60
carrying the pins 10 and moved by the key which is operated from the outside
If therefore the disc 56 is in position to be in contact with the cam 57 when the
bolt is being unlocked, the cam 57 turns the disk 56 so as to transmit motion
through the wheela 54 and 53 to the hour wheel 24, in the direction opposite
to that in which the hour wheel us normally rotated there being sufficient slack to
allow of a slight backward movement This slack is accordingly taken up and
the dial is slightly moved from the position where the perforation 18 made in
locking and thus a second perforation is made in the dial registering unlocking
immediately after locking, and an effectual check is thus afforded against dishonest
manipulation of the lock For the purpose of keeping the disk 56 in the path of
the cam 67, a spring 61 connects the swinging arm 55 with a sciew 62
to prevent the second perforation from being made except between certain hours,
I employ a lever 63 arianged to press against the swinging arm 55 and thus take
the disk 56 out of the path of the cam 67 so that its rotation can have no effect
upon the wheels 53 and 54 At this tame the lever 63 us pressed by pegs 64 on
the dial plate 27 these pegs being so arranged as to keep the lever 65 in this
Thus the dial
position between certain hours during which business goes on
records not only the time when the place 18 closed for business but also the
time when it is opened up for business, and if there has been any movement
of the bolt between these hours a record of it 18 made and its time is indicated
by the second perforation of the dial The position of the parts for making the
second perforation is shewn in Figure 1 and their position for not making it 18
shewn in Figure 2. The arrangement of these parts in Figures 1 and 2 is for a
right hand lock For a left hand lock they are arranged as shewn in Figure 4
where an intermediate pinion 65 is used to change the duection of rotation
of 53
In order
For the purpose of holding the aim 48" of the rock shaft 47 in position at all
times for the arm 50 to engage it I employ a set screw 66 as illustrated in
Figure 1
By the arrangements described I have improved locks of this general character

page_text: so that I dispense entirely with the use of a master key making one key answer
for manipulatung the lock and registering the time of locking and unlocking I
also make the mechanism more compact, and simple and less expensive than
heretofore, besides providing means for guarding against improper manipulation
of the lock during the hours when the place is not open for business by making a
record of such manipulation
In the construction described the escapement 67 is placed at the top of the
mechanism where it is easy of access, it is effectually protected against dust by
providing a casing 68.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:
1. A registering time lock substantially as described with reference to the
accompanying drawings
2 In the registering time lock above refered to, in combination with the lock,
clockwork moving a registering disc and a punch, and mechanism connecting the
lock bolt with the punch, so as to cause it to puncture the disc when the bolt is
moved, substantially as described
3 In addition to the mechanism above referred to for operating the punch,
auxiliary mechanism causing the punch to make two punctures when the lock
bolt is moved rapidly to and fro, and means of disconnecting the additional
mechanism during business hours, substantially as described
