Improvements in Workmen's Time Recorders.
A communication by WILLARD LE GRAND BUNDY, of 136, Murray Street,
Binghamton, in the County of Broome and State of New York, United
States of America, Mechanical Engineer, and THE BUNDY MANUFACTURING
COMPANY, of Binghamton, aforesaid, Workmen's Time Recorder Manu-
facturers.
I, WILLIAM
PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 31, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to workmen's time recorders, and particularly to that class
in which a numbered key is used to designate each workman, by its numeral, and
which is inserted into the machine, turned to actuate the printing mechanism and
then removed, leaving said numeral and the hour and minute numerals printed onto
a strip of paper, the latter numerals being carried upon time wheels which are
connected to and synchronous with a clock-movement.
The object of this invention is to improve the construction of the machine,
increase its utility and durability and to provide it with additional safeguards,
such as have been developed by the manufacture, sale and use thereof. And to
that end, this invention consists in the several novel features of construction and
operation hereinafter described.
It is constructed as follows:-
The machine contains a front plate and a back plate and corner posts connecting
them. A shaft is connected to and rotated by a clock movement, and has a
bracket supporting and guiding it, and by the bevel gears, spur gears and shaft,
the spur gear and the minute wheel loose upon the arbor are rotated so that this
minute wheel is synchronous with the minute hand of the clock. The rotation of
the shaft rotates the cam, which engages with the stud to lift the lever, which is
provided with a counter-balance and a spring-pawl, which normally engages with
the ratchet wheel secured upon the hour-wheel and shifts said pawl once in each
Lour into engagement with the next tooth, and has a stop pawl to prevent the
backward rotation of said hour wheel, which is thus shifted once in each hour.
The stop pawl is provided with an arm and has a spring connected thereto and
to the arbor. A rock-shaft is journaled in the front and back plates and has a
helve secured thereto, has a platen or hammer secured upon said helve and also has
a spring connected to an arm on said rock-shaft and operating it to hold said platen
normally in a given position. A bar is secured to the inner face of the front
plate, and concaved, and cut away on top, said concavity being in alignment with
the key-hole and has a tube fitting rotatably in said concavity, adapted to receive
the stem of the key and slotted longitudinally to permit the bit or ward to enter,
so that the turning of the key rotates said sleeve, and when turned one-quarter of
a circle, the bit or ward will strike the face of the bar and stop the key. The
key is provided with a ward having upon its outer end the numerals or characters
used to designate a workman, and an arm beveled or scarfed off on its outer end.
A frame consisting of two parallel bars united by a rod is secured to a rock-
shaft, has a key-lock, gravity pawl pivoted upon an arbor in said frame and

page_text: provided with teeth on its face with which the key-arm engages when the key is
turned, and thereby the key cannot be turned back and removed until it has fully
passed said teeth and then said arm will engage with the back thereof and tilt it,
when the key can be withdrawn and the pawl will drop back into its normal
position. Said pawl is provided with a lug which will engage with the rod when
it is tilted and which thus regulates and limits the degree of said tilting, and
prevents its being thrown over back out of the path of the key-arm, which if it
occurred, would disable the machine.
As this pawl normally lies against the rod, the turning of the key swings said
frame, rocks the shaft, swings the lever, and through the connecting rod and crank
secured to the rock-shaft, rocks said shaft to throw the platen into position ready
to strike an impression blow, producing a torsion upon the spring, so that when
said key-arm reaches the limit of its movement, the numerals upon the key are
upon the printing line, and said frame is released, so that said spring impels the
platen to strike an impression blow and print the key numeral and the hour and
minute numerals of the time-wheel, which are then upon the printing line upon the
paper-strip by the aid of the ink-ribbon.
In the key-tube a notch is cut and when the key is turned, said tube is rotated,
and when the key is stopped the point of the pawl drops into this notch, aided by a
spring, and this locks the key, and not only prevents it from being turned back,
although it has passed the lock-pawl, but also holds it in that one position until
the impression platen strikes its blow, and when this occurs the stud on the platen
strikes the beveled end of this pawl and raising it out of said notch releases the
key to be removed.
The paper-strip is conducted from a suitable reel through a guide, thence
upward in front of the platen and through a guide which is adjustable by means of
a slot and screw and thence extends upward to the wind-up spool. The rocking of
the shaft oscillates an arm thereon and has a rod connected thereto by means of a
head and a pivot-pin, and said rod leads up to and is connected to a pawl-holder,
which comprises an arm pivoted upon the spool-shaft and a flange provided with a
slot-way through which a screw passes loosely into said rod, and has a spring
connected to said rod and to the body of the paper guide, and exerting its tension
to yieldingly hold said rod at or adjacent to the heel of said slot, and to hold the
finger on said 1od in contact with the paper on the spool, so that as the amount of
paper on the spool increases, said finger will be forced outward thereby, and will
the rod outward and shift its bearing in said slot, and said finger in
conjunction with said spring will hold said rod at any bearing point it may
carry
assume.
A spring-pawl on the holder engages with a ratchet loose upon said shaft, but
secured to a sleeve upon said shaft is one of the spool-heads also secured to said
sleeve, said shaft being carried by a bracket erected upon a corner post.
The drum of the spool is tubular and has an outer head thereon, said drum being
provided with a longitudinal slot, a head within said drum notched, coincident
with said slot, and has teeth upon the edge of said slot which engage with the
paper to hold its end upon the spool.
In the spool-head, a stem is secured and adapted to pass through a slot in said
drum-head, and connects said spool-drum to the inner head, so that all rotate
together, said stem being provided with a spring catch, which detachably holds
said drum in position, so that at any time the drum can be readily pulled off
from said shaft for the inspection or removal of the printed paper strip wound
thereon.
A check-pawl engages with said ratchet to prevent any backward rotation of
the spool. The ribbon is connected to the spools and is wound from one to the
other by the following mechanism; and which comprises a rod connected to an
arm carrying a pawl in engagement with a ratchet and this rotates a gear which is
journaled upon an arbor secured to a swinging bar, pivoted so that by shifting said
bar, said gear is shifted out of its engagement with one pinion into engagement

page_text: with the other, said pinions engaging with gears upon the shafts of the respective
ribbon spools, whereby a step-by-step rotation is imparted to one spool to wind
the ribbon from the other, each time a key is inserted and turned to vibrate the
impression platen.
A cam engages with a pin upon the arm of the shifting bar, and its rotation lifts
said bar, raising the pawl clear from the ratchet, then engaging with a stop ou
said bar, and when the cam is released from said pin, the bar drops and the pawl
engages with another tooth on said ratchet. As the pawl descends it engages
with a pin on said arm and throws the stop out of engagement with the ratchet,
and then the pawl rotates the released ratchet and hour wheel until the pawl passes
the pin a spring throws the stop back into re-engagement and stops the hour-wheel
against movement in either direction.
In the ribbon feed mechanism, the rotation of the ratchet, rotates a gear,
pinions, shaft, pinions and gear, and the shaft of the spool, and when the gear is
shifted into engagement with the pinion the next pinior is rotated together with
said shaft and pinion, gear, and the shaft of the spool. A pin on the shifting-bar
engages with one of the holes to hold the gear in either engagement.

A communication by WILLARD LE GRAND BUNDY, of 136 Murray Street,
Binghamton, in the County of Broome and State of New York, United
States of America, Mechanical Engineer, and THE BUNDY MANUFACTURING
COMPANY, of Binghamton aforesaid, Workmen's Time Recorder Manu-
facturers.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street, Manchester
both in the County of Lancaster, 118 New Street, Birmingham, in the County of
Warwick and 31 High Holborn in the County of Middlesex, Civil Engineer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to workmen's time recorders, and particularly to that class
in which a numbered key is used to designate each workman by its numeral, and
which is inserted into the machine, turned to actuate the printing mechanism and
then removed, leaving said numeral and the hour and minute numerals printed on a
strip of paper, the latter numerals being carried upon time-wheels which are
connected to and synchronous with a clock-movement.
Several Patents have heretofore been acquired by my correspondents for
machines of this class, viz. 17510, 151820, 3092", and the object of this invention
is to improve the construction of the machine, increase its utility and durability
and to provide it with additional safeguards, such as have been developed by the
manufacture, sale and use thereof.
And to that end the invention consists in the several novel features of construction
and operation hereinafter described, and which are specifically set forth in the

Fig. 31 is an enlarged elevation of a character sign or symbol used to show the
exit of a workman.
Fig. 32 is a plan of part of a paper strip with records printed thereon.
The machine contains a front plate a (Figure 1) a back plate 6 (Figure 2) and
corner posts c (Figure 3) connecting them. A suitable shaft 2 is journalled in and
supported by a bracket 3 (Figure 3) and is connected to and driven by a clock
movement (not shown). This shaft carries a bevel wheel 4 and drives thereby a

page_text: bevel wheel 5 and a spur gear 6, both secured upon a shaft 7 (Figure 3). The
spur-gear 6 drives a spur-gear 8 (Figure 6) and a minute wheel 9 secured thereto,
said spur-gear 8 and minute wheel 9 being both loose upon an arbor 10 (Figure 6),
so that the minute wheel is there by rotated and is synchronous with the minute
hand of the clock.
A cam 11 is secured upon and rotated by the shaft 7 (Figures 3, 22, 23, 24
and 26) and engages with a stud 12 to lift a lever 13 having a counterbalance 14
upon its free end.
A spring pawl 15 is pivoted upon said lever and is normally in
engagement with a ratchet 16.
This ratchet 16 is secured upon an hour wheel 17
which is loosely mounted upon the arbor 10 alongside of the minute wheel.
A stop paw! 18 is normally held in engagement with the ratchet 16 of the
hour-wheel, by a spring 20 connected to the arbor 10 and to an arm or
stud 19 on said stop pawl (Figures 5 and 6). These parts constitute the time
mechanism.
A rock-shaft 21 (Figure 4) is journalled in the front and back-plates and a
helve 22 carrying an impression platen or hammer 23 (Figures 4, 5 and 7) is
secured to said shaft. A spring 24 (Figure 5) is connected to an arm or stud 25
on said rock shaft and normally holds the platen or hammer in the position shown
in Figure 5.
A bar 26 is secured to the inner face of the front plate and longitudinally
concaved as at 27 (Figure 12) to receive a bushing 29 in alignment with the key-
hole 28 (Figure 1). This bushing is tubular and slotted longitudinally to receive
the stem or shank of the key 30 and the ward 32 thereon (Figure 12) so that the
turning of the key rotates said bushing and when turned one-quarter of a circle,
the ward strikes the face 31 of the bar 26 and stops the key so that the numerals
or workman-designing characters upon this ward (Figures 20 and 21) lie in the
printing line of the machine. The key is also provided with an arm 33 beveled or
scarfed off on its outer end, as shown in Figs. 10 & 20. A frame 34 (Figs. 7, 8, 9)
consisting of two parallel bars united by a rod 35, is secured to a rock-shaft 36,
and 37 is the key-lock-gravity pawl pivoted upon an arbor 38 in said frame, and
provided with teeth on its face with which the key-arm engages when the key is
turned, to force the pawl against the rod 35 and swing the frame 34 so that the
key arm 333 enters the notches in succession and is wedged therein (Figure 10) by
the tension of the spring 24 exerted upon the shaft 21 and thereby the key cannot
be turned back and removed until it has fully passed the said teeth, and then the
said arm will engage with the back thereof and tilt it substantially as shown in
Fig. 11, when the key can be withdrawn and the pawl will drop back into its
normal position as shown in Fig. 8. As shown in this figure and also in Figs. 10
& 11, said pawl is provided with a lug 39 which will engage with the rod 35 when
it is tilted, and which thus regulates and limits the degree of said tilting, and
prevents its being thrown over back out of the path of the key-arm, which, if it
occurred would disable the machine. As this pawl normally lies against the
rod 35, the turning of the key swings said frame 34, rocks the shaft 36, swings the
lever 40, and, by means of the connecting rod 41 and crank-arm 42, secured to
the rock-shaft 21, rocks said shaft to throw the platen into the position shown in
Fig. 7 by the dotted lines, ready to strike an impression blow, producing a torsion
upon the spring 24 so that when said key-arm reaches the limit of its movement,
the numerals upon the key are upon the printing line, and said frame is released so
that said spring impels the platen to strike an impression blow and print the key
numeral, and the hour and minute numerals of the time-wheels, which are then
upon the printing line, upon a paper-strip m by the aid of an ink-ribbon 43. In
the key-tube a notch 44 is cut, (Fig. 12) and when the key is turned said tube is
rotated, and, when the key is stopped, the point 45 of the pawl 46 drops into this
notch aided by the spring 47, and this locks the key-bushing 29, and not only
prevents it from being turned back, although it has passed the lock-pawl 37, but
holds it in that one position until the impression platen strikes its blow, and when

page_text: this occurs the stud 48 (Fig. 4) on the platen strikes the beveled end 49 of this
pawl 46, and, raising it out of said notch, releases the key to be removed.
The paper-strip is conducted from a suitable reel (not shown) through a
guide 50 (Fig. 5) thence upward in front of the platen and through a guide 51,
which is adjustable by means of the slot and screw 52, and thence extends upward
to the wind-up spool.
An arm 54 (Figures 5 and 7) is secured to the shaft 36 so that when this shaft
is rocked, the outer end of said arm is alternately raised and lowered, thus
imparting a vertically reciprocatory movement to the rod 55 which is loosely
connected to said arm by a pivot pin 57 through an enlarged opening in the
head 56 secured to the rod 55, so that a short movement of the key 30 will not
cause any rotation of the reel 72 to feed the paper. This rod 55 is connected to
the pawl carrier 58 (Figures 13, 14 and 15) consisting of an arm 59 pivoted upon
the spool shaft 60 having a flange 61 provided with a slot way 62 through
which the screw 63 is inserted, thereby loosely connecting it to said rod 55.
64 (Figure 5) is a spring connected to said rod and to the paper guide 51 to
yieldingly hold said rod (and screw) at or adjacent to the heel of said slot.
This spring also holds the finger 65 which is secured to the rod 55 in yielding
contact with the paper on the spool, so that as the diameter of the spool increases,
said finger will be forced outward, and thus automatically regulate the spacing
stroke of the crank arm 42 by shifting the position of said screw in said slot 62
and holding it at any bearing point it may assume.
A spring pawl 66 on the holder 58 engages with a ratchet 67 which is mounted
loosely upon the shaft 60 but is secured to a sleeve 68 upon said shaft, and 69 is
one of the spool heads also secured to said sleeve, said shaft being carried by a
bracket 70 erected upon said corner post. The drum 71 (Figures 16, 17, 18, 19)
of the spool is tubular, and 72¹ is the outer head thereon; said drum being
provided with a longitudinal slot 73, a head 74 within said drum, notched as at 75
co-incident with said slot, and teeth 76 upon the edge of said slot which engage
with the paper to hold its end upon the spool.
In the spool-head 69, a stem 77 (Fig. 17) is secured and adapted to pass through
a slot 78 (Fig. 19) in said drum-head 74, and this stem connects said spool-drum
to the inner head 69 so that all rotate together, said stem being provided with a
spring-catch 79 which detachably holds said drum in position, so that at any time
the drum can be readily pulled off from said shaft for the inspection or removal of
the printed paper strip wound thereon.
A check-pawl 80 (Figs. 5, 15) engages with said ratchet to prevent any
backward rotation of the spool. The ribbon 43 is connected to the spools 81
and 82 (Figs. 5, 6) and is wound from one onto the other by a mechanism which
consists of a rod 83 (Fig. 2) connected to the arm 54 and carrying a pawl 84 in
engagement with a ratchet 85 (Figs. 2, 27), and this rotates the gear 86 which is
journaled upon an arbor 87 secured to a swinging bar 88 pivoted at 89, so that by
shifting said bar, said gear is shifted out of its engagement with one pinion 90
or 91 into engagement with the other, said pinions engaging with gears 92 (Fig. 5)
upon the shafts of the respective ribbon spools, whereby a step-by-step rotation is
imparted to one spool to wind the ribbon from the other, each time a key is inserted
and turned to vibrate the impression platen.
The cam 11 in rotating engages with a pin 12 upon the arm 94 of the lever 13,
and lifts said lever, raising the pawl 15 clear from the ratchet 16, after which, said
cam leaves the pin 12, whereupon the lever drops and the pawl 15 engages a tooth
on said ratchet 16. As the pawl 15 descends it engages with a pin 96 (Figs. 24,
25, 26) on the arm 18 and throws the stop 97 out of engagement with the ratchet 16,
and then the pawl as the lever further descends rotates the released ratchet and
hour-wheel until the pawl passes the pin 96; a spring (not shown) then throws the
stop 97 back into re-engagement (the pin 96 passing through a channel in the back
of the pawl) and stops the hour-wheel against movement in either direction.
A

page_text: tension spring returns the pawl to its normal position when the lever 13 has again
ascended.
In the ribbon-feed mechanism, the rotation of the ratchet 85 rotates the gear 86,
the pinion 91, the shaft 98, pinion 99, gear 92 and the shaft of the spool 82; and
when the gear 86 is shifted into engagement with the pinion 90 this pinion is
rotated together with the shaft 101, pinion 102, gear 92, and the shaft of the
spool 81. A pin on the shifting bar 88 engages with one of the holes r to hold the
gear 86 in either engagement.
In Fig. 31 the star marked 104 is shown which can be used to designate the exit
of a workman; and in Fig. 32 is shown a piece of a strip of paper with records
thereon, which records show that workman 269 entered at 7:15 and left at 7:18,
while 268 also entered at 7:15, said star-mark being upon the inner end of the
lever 105 (Figs. 1, 2, 5) which latter is pivoted so that when it is raised its inner
end will swing said mark onto the printing line.
In Figs. 22 and 23 the cam 11 is shown as provided with a slit in its straight
face, whereby a tongue 106 is created, said tongue being adjustable as to its
projection beyond the direct line of its face. From this it results that, as said
cam is driven by the same train of gearing in connection with the clock-works,
when the cam passes the stud 12 and the lever falls to shift the hour-wheel, it,
at the same time, strikes the tongue and forces the cam to rotate forward far
enough to cause the train of gearing to be rotated so as to rotate the minute wheel
one space, simultaneously with the movement of the hour-wheel.
This is essential where the minute wheel has normally only a regular forward
movement, whereby, when for instance, the two wheels indicate 6:59, the rotation
of the cam causes the hour-wheel to shift while the minute-wheel is still at 59, so
that the time on the paper strip indicates 7:59, whereas it should show 7:00, which
fault is wholly remedied by the above device.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
