SAMUEL filMPSON BERRY, OF MANCHESTER, ENGLAND.

AUTOMATIC WORK-RECORDING APPLIANCE.-

Application filed Kay 22,

To (all whom it may cancer-11,:

Be it known that LSAMUEL SIMPSON BER- RY, a subject of the.King of Great Britain and Ireland, and a resident of Urm'ston, Man

5 chester, England, have invented a certain new or Improved Automatic Work-Recording Appliance, of which the following is a specification.

This invention has for its object to provide a simple and inexpensive: arrangement of mechanism whereby a 'permanent record maybe obtained of any form of mechanical operation, such as the workdone by a printing-machine or a box-making machine or the like,.or even the revolutions of a turnstile;

and -a further object is so to-construct, arrange, and operate the mechanism that hesides indicatin numbers or like data it will also indicate t e rate of progression, as well 0 as the stoppa es and the duration of such 5 worked at a istance from the machine, and

thus permit of such parts being kept in, say,

" the oilice of a works or at a private residence,

and therefore removed from the person using the machine and under the eye of the person b requiring the record.

Accordim to the invention, I em loy a drum or endless band to which Hit a sheet of aper, hereinal'etr called. the time-sheet. lpon such time-sheet are lines or markings 3 representing divisions of time and also me merals denoting the hours of the day (or longer) and, if desired, the fractions of each hour. To the axis of this drum is geared a suitable motor, preferably of the springclockwork type and designed to rotate the drum at a speed which repres(. .nts one hour for each-division on the time-sheet.

Resting upon the drum is the point of a style or pencil, and such pencil is adjustably carried at the free end of a small plate or lever, hereinafter called the recordlug-lever.

'lhis lever is mountezl upon a horizontal axis andis capable of a slight to-aud-l'ro movement.

Adjacent to the opposite end of the recording-lever is an ele'ctromagnet or solenoid. From the'windings of the magnet-poles extend conducting wires to aswitch near the machine, a'suitable battery being included in the circuit.

Connected to the operative part of the Specification of Letters Patent.

switch is a suitable moving part of the machine which at every revolution acts as upon the switch in such a manner as to cause the switch at each impulse or after a series of impulses to complete the circuit of the electromagnet and by energizing the magnet at tract and impart movement to the recordinglever, which, carrying the pencil, marks the time-sheet. L 6 5 Upon the switch beingmade free the circuit of the ma net is broken and the lever and pencil um er the force of a spring return to their-former ositions until the curthey are again actuated and the time-sheet again marked, and so on continuously.

.To allow for the ready calculating of the strokes, (especially when the peripheral speed of the drum is very slow,) provision is made whereby, say, every twentieth stroke is'lon'gerthan the other, this being cil'ected by means of a notched disk-and-ratchet mechanism and a small projection on the recording-lever. Thus with the switch closed 80. at every fourth sheet the lengthened mark will indicate every one hundredth sheet. A The projection under the impulse of the lever strikes the periphery pf the diskfor each short stroke, while under the impulse representing each twentieth stroke the said ro- 'jection takes into the notch, and thus al ows for a longer stroke on the recording-druid. The disk is rotated oradvanced tooth by tooth by means of a pawl, and thus works in- 0 sympathy with the making and breaking of the circuit. By means of a retaining-sprin and pawl the wheel and disk are prevente Y returning, and the movement is equal for each impulse. :9 5

. By extending the length of the drum and providing the sheet with separate divisions and also by providing a separate switch, magnet, and lever for each the workdone ona series of machines may' be recorded on the 1cm one drum.

Upon the accompanying drawings '1 have -a shown my invention as designed for recording the work done on five machines, this be' ing an averageexample and serving wcllto 1C5 demonstrate the general characteristics of the invention.

F 2 illustrates a geometric frontelcvation withthe front of the casing removed and withcertain' parts in section. Fig. 3 illus-- trates a part-vertical cross-section. Fi 4 1:) illustrates a front view, and Fig. 5 a vertical section, of the switch part of the a paratus which is applied to the machine an is actuated by a moving part of the machine. Fig.

. 6 illustrates to an enlarged scale a side eleva- 5 tion, Fig. 7 a top plan, and Fig. 8 an inverted plan, of the chief arts of the recording mechanism. Fig. 9 il ustrates a front View of the recordi -lever. Fig. 10 illustrates a plan of a;time-s eet after being removed from the :o drum and showin typical markings for the five machines. Fig. 11 illustrates a longitudinal section, and Fig. 12 a right-hand end view, of the drum alone. Fig. 13 illustrates the manner in which the motion of the drum 2 5 may be utilized'for preventing the undue exhaustion of the batteries.

Keferring to Figs. 1', 2, and 3, the whole of the recording a paratus is inclosed in a casing 1, preferab y of wood (mahogany) and su1tably finished (polished) to give-a neat and pleasing outward a peai'ance and such as to make it suitable to 1 1x in an office.

At one end of the'casing .and supported upon a partition 2 is the spring-motor 3, w

casing being formed with a glazed door 4, through which shows the clock-dial 5. Within the other art of the casing, which is provided "with all tered or takes its bearings between a sp ressed pin or center Q and a cone 10, this atter being fixed to the axis 11 of the motor 3. The motor is. referably of the doublespring type, and t c axis 11 is preferably t at of thefirst-motion member, so as to give a powerful, ositive, and uniform drive.

Around t e drum is wrapped and fixed a sheet of-pa r, (see Fig. 10,)the length of which equa s or slightl exceeds the circumference of the drum. 1 on the face of such paper, which is preferably of a glazed finish or such as to take an impression when rubbed by a metal style are rmted the several-vertical lines a an marlrings b, (see Fig. 10,) the lines produc' an annular column or space for the reco r ifof each machine and the markings corresponding to the peripheral speed of the drum for the twelve hours of the Go.

da a r pon a rail 12, secured to the top of the casing 1" -and' ,above the drum, is a.series of brackets 13, and upon each bracket and between two lateral ex tensionrlt 14 thereof isan elsetromagnet15, the poles of which are ich also serves as a clock, the end of the.

inged and glazed front 6, is the.- 4-3 drum 7, mounted upon axis 8, which is cenriveted through the said extensions 14 14, and thereby cause the extensions to act as the poles roper.

In rout of each magnet is a plate 16, which extends from a point above the upper exten- 7o sion or pole piece 14 to a point belowthe lower extension or pole piece 14* and such plate at its upper end isv provided with a screw 17, the point of which okes loosely into a small recess in the end of the pole-- piece 14" and forms a fulcrum for the plate.

By means of'a spring 18 and an adjustable connectingiece 19 t e upper' and shorter end of the p ate 16 is connected to the bracket v 13 or otherfixed object, and by reason of the tension of the spring the loweryend of the plate 16 is normally held clear of the lower ole-piece 14"",as shown in 6. At its ower end the plate 16 terminates in ascrewclamp. 20, winch serves to attach a sprin'gblade ,21, which at its free end carries the I recording pencil or style, the plate 16, blade 21, and style collectively forrmng the recording-lever. The length and posltion of the lever are such as to cause thepencil or st le to 0 he opposite the axis of the drum (see igs. 2 and 3) .and with the point just clear of or only lightl resting against the time sheet. "The said 0 amp 20 of each'plate 16 passes throu h a slot 22 in the horizontal member of t e 5 bracket 13,'and thesaid-slot lies diagonaLto the said member, as shown mdne clearly in Fig. 8 sothat on the recording-lever being caused to move toward the magnet its lower end has a compound movement-first, a zoo movement toward the magnet, and, second,- laterally; In such way the style or pencil is caused to mark the time-sheet, the double movement insuring of the length of stroke and the, requisite pressure for making such :05 stroke,while the return movement insures of the drum beingrelieved of the pressure of the style when not in operation. The said compound or diagonal movement, however, serves also for a further purpose.-namely, no the rotation of a ratchet-wheel 23 and notched disk 24, mounted upon a fixed pin or axis 25 on bracket 13, b means of a pawl 26, this latter bein carrie loosely by the recording-lever and held in play with the teeth 1 15 of the ratchet-wheel 23 by a-'spri ng 26".. with each inward impulse of the recordin'glever the pawl advances the ratchet-wheel one tooth. In the plate 16 is a set-screw 27,

projecting beyond the rear face of the plate no and at a point directl opposite the periphery of the wheel 24.- n the wheel 24 is the notch or recess 28.

With each impulse of the recording-lever toward the m et the screw-point 27 12 5 strikes the perip ery of-the wheel 24,,the plate 16 not quite touching the magnetpoles, and thereby causes the strokes or marks made by the style on the time-sheet to be of equal length. Due, however, to the notch, which comes opposite the screw-point once in every complete revolution of the Whole, the movementof the lever at that point is greater, and therefore causes a correspondingly longer stroke to be impressed on the timtssheet.

By meansof asmall screw 29 the recordinglever is readily adjusted in relation to the poles of the magnet.

The foregoing description applies to each bracket and magnet, the several brackets lying side by side and being exactly the same for any number of" machines an the drum being made long enough for the series.

To facilitate the ready introduction and removal of the drum, the floor of the casing is hinged and turns downward, (see Fig. 3,) and by means of a projecting plate 30 and a recess in the. inner face of the door 6 the fastoning of such door serves also to fasten the floor part. To allow of tilt floor part turning downwcr' the casing will be mounted on brackets 31 or upon a stand or be's'uspended from an overhead support.

Referring now to Figs. 4 and 5, which show the parts associated with each maclnne, 32 is a small metal casing designed. to be fixed by a couple of screws to the machine at a point adjacent to a'moving or rotary part. W ith in the said casing are two terminal springeontact blades 33, normally lying apart and one bent so as to readily approach and make contact with the other and afterward separate of its own elasticity. Connected with such blades by suitable conducting wires is one of the magnets 15 of the recording apparatus (see Figs. '2 and 3) and ameleetrie battery or other generator of electricity; Mounted upon a short axis 34 within the casing and extending through an opening in the top wall of the casing is a lever 35, which forms the operative part of the switch hereinbefore referred to. To the end of the lever outside the casing is imparted the motion of the rotary part,of the machine, which may be by means of a tooth (or teeth) on th c' said rotary part periodically pressing against the said lever, while the lever is returned by a spring after each impulse, or which maybe by means of an eccentric-pin 36 in the end of a shaft, (see Fig. 1,) which, projecting throughaslot in the lever, wags or moves the lever to and fro as the shaft rotates. ()ther ways or means may be employed, the chief requirement being to move the lever to and fro.

la the example shown in F g. 1' the casing is fixed to the lower beating-brass of the shaft, and thus allows of the convenient engagenu at of the level: with the pin 36. Intermediate of the end of the lever Within the casing and the blades 33 are means whereby at each stroke of tin lever or, by reference, after a number of strokes the )lades are caused to meet, and thus complete the electric circuit of the said battery and the magnet in the casin 1, whereby the recordinglever is attract and the time-sheet marked with a stroke. The said intermediate means may take. various forms; but in practice I find that the arrangement requires to be one which allows of a sufficiently longcontact of the blades 33 to 'nsure the full movement of the recording-lever no matter how rapid the machine be running, and l als-i find that the arrangement requires to be such as will allow caused to inflate the btllows or cap, ano th-Lreby ress cne blade against the other. The saiz arrangement also consists of a ratchet-wheel 40 and a cam-wheel 41, setcured to eimh fothrr, but loos.ly mounted on the axis 34 of a love-r43, loosely engaging tln piston-rod 44 and formed with a shoulder or tooth which undcrthe pull 'of the )iston-spring 42'presses against the whee 4l lever 35, and of a spring-prtsstxi retainingpawl 46.

In tbe'examplt. shown in Fig. 4 the ratchet wheel has twenty teeth and the cam-wneel' four teeth. For each forward stroke of the lever the ratchet-wheel is advanced one tooth, which in the case of a printing-mashcet of paper or other unit of o )eration to be. countt d, or it mayc'orr. sponrf with a Series of such units. As the ratchet-whe l is rotated one of the teeth of the camwhee.l is gradually prt ssing out the lever 43 and drawing the piston 3 7'to the opposite end of the cylinder; but as soon as the ratchetwheel has been advanced five teeth the shoulder ortooth on the lever 43 slips off the highest or deepestpart of the cam-wheel tooth and allows the piston 37 under the force of'its spring 42 to suddenly move back to the opposite end of the eylind er and there by inflate the cap 39 and make contact be- .twceu the blades 33, thereafter rapidly deflating, (due to the slack fit of the piston,) but holding tne blades together longer than an ordinary mechanical appliance would I usually allow. By the time the ratchetwhetl has been advanced five more teeth'the piston has been again drawn out and again released, the cap 39 again inflated, and the blades again brought into contact, and so on for each five teeth of the ratchet-wheel. and each teeth of the cam-wheel. Should the machine stop just as the piston has inflated of a sprmg-pressed pawl 45,carried by the. 7

in the cylinder and between the piston ischine may co respond to the printing of one particular requirements of each U 4 will the cap, it will be seen that the exhaustion; of tne cap will thei eafter allow the blades to separate, and therebyprevent the batteries running down, as nught be the caseif the blades remain ed in contact until tne machine was restarted.

Assuming the electric circuit of the magments of the lever 35 the manner of recording the operations may be varied to suit the case. gon the time-sheet shown in Fig. it e seen how the user may determine b3 the. strokes the amount of work done, the time taken to do the work, and by'the gaps or blank s aces between each set of strokes in each co umn how long each machine was idle.- For example, in column -1 the map chine started at'six oclock, sto ped at 8.30 3

o'clock, started again at te oc ock,.ran on until twelve oclock, resarte l at two oelocl stopped again at f0"? oelock, started again at. 4.10, and ran on until oclock. From the second columnit will be seen that the i ate ofproduction was gieater, the machine being a quicker-running machine. To en-- able the man in charge of the machine to have a check on the work done, the switch may include a counter 48, (see Fig. 5,) driven from the axis 34 by, say, a pegwheel 48 To provide for the obtaining of a record when working overtime. or for making the timesheet serve for more than one day, the sheet- -may be printed with markings for a longer, 'period and the drum he s eeded down to suit, or instead of a drum a elt may be used; but as a dailv record will be the most usual and a recor of overtime will cz'ly be required occafonally I find it best to use the one-day time-sheet and to provide means whereby the drum may be moved longitudi-' nally and bring a fresh blank space into the line of the recording-lever. To do this, the drum is mounted loosely on its axis 8, and at one endthe said axis is screw-threaded and provided with a put 8*, (see Figs. 3 and 11,) while at the other end it is provided with a bow spring 49,- the ends of which press against the end'of the drum and hold the oposite end of the drum against the nut 8", so

that after the drum has made a complete rev.

olution and fresh spaces are required for receiving the markings of the pencils for overtime the slackening oi the nut 8" will allow the drum to move along its axis under the force of spring 49 .until the r uired blank s aces come opposite the perici s, wh'emthe rum can then rotate and take the-reobrd' of the further work alongside the work previously recorded. (See-Fig. 11.) To allow for both theaxial adjustment and positive drive of the drum, the s ing 49 is fast on the axis, the drum end is s otted, (see Fig. 12,) and a small pin 51 on the end of the spring 49, taking into the slot, causes the spring to drive=the drum positively, while allowing of the endwise movement.

In Fig. 13 I howhow the motion of the drum may serve for alternately switchin ion and off separate batteries used-in wor mg the magnets 15, a divided ring 52 on the drum-axis and two terminals 53 being used, with one terminaflpressing against one'part of the ring and the other against the other" partand the said parts of the ringbeing m circuit with the two batteries, solthat asthe ring rotates the'termi'nals make circuit first with one battery and then with the'other,- and thus-enable the batteries to beused for a much'longer period-than wonldbe possible with a-battery or batteriesin constant use. In practice, however, I do not find-this arrangement necessary for recording the work dorieby a small number. of machines, but for a large number it will doubtless It will now be seen that with the recording.

apparatus shown in Figs.- '1, 2,:aud3' only" connected electrically with the partsfshownin Figs. 4, 5, and fithe said apparatus and 'its casing may be kept or'used in places-removed a considerable distand'a from thu machine or machines, and therefore inthe ease of works will allow of the recording mechanism being kept in, say, the oflice or the manager's room.

- Due to the character of'the record it will also be se n that the apparatus will-.'be of greptgrse in casting piece: .k, making up waea-testing the economy of the machines, an finally,

will serve as a-- telltale against idleness in the absence of the principal or manager. With the clock showing at one end of the casing the apparatus will also serve as a time iece.

To allow for the holding ofthe st was or pencils 'clear of the drum while the rum is eing introduced gorrenewed, a bar 54 (sec 2) may be used, lying immediately behind the recordinglevers anddesignedto lie, as shown, or be turned up to the horizoniil and against the blades 21, and thus hold 't e several styles away from the drum.
