RECORDING MECHAN ISM.

Specification of Letters Patent.

Application filed September 17, 1909. Serial No. 518,243.

Patented Mar.18,1913.

- To all whom it may concern:

Be it known that I, GEoReE WILSON, of Boston, in thecounty of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Recording Mechanisms, ofwhich the following is a specification. I

This invention relates to automatic mechanism for recordingthe operations of machines.

In the present embodiment of the invention the recording apparatus is especially adapted for recording successive operations oflaundry machinery, and the invention is to directions. I

In carrying out the invention a clock a movement or other timing mechanism is provided and equipped with a piece of material adapted to receive a mark, and with a marking device arranged to produce a mark, said elements being so related as to produce a mark in the form of a continuous line.

The device-upon which the mark is recordedmay for convenience be a disk of I paper previously marked with divisions cor- I responding to units. of time, whereby the mark recordedthereon may show the duration ofeachoperation and the time of day when each operation is begun.

For the sake of clear illustration the invent-ion is herewith illustrated in connection with other automatic mechanism, which forms the subject-matter of an application for patent filed by me July 27, 1909, Serial No.- 509,881. I

' One advantage of the resent invention inures to the benefit of t e'proprietor, as hereinbefore stated, by showing the'work done by each machine. The proprietor is therefore inrajposit-ionto know whether his operative is faithful in the performance of hisdu'ties. Another advantage is that the operative ma'y,-by meansof the record, show the proprietor what has been done with the machines under his direction. A third 'advantage is that both the proprietor and the operative may, by means of referring to a recordand the quality of the work performed by the machine, determine whether the machine is being operated in such a way as to give the desired results. For instance, it is the custom in carrying on a laundry business to provide the operatives with formulas including explicit directions for-the compounding of the various fluids and the periods required for operation. If, upon examination of the work it is found that the articles are washed, blued or bleached more or less than is desired, and the record of the operation is consulted, it may be found that the formula calls for too short or too long a period of operation. i I f Referring now to the. drawings, which illustrate onermanner in which the invention may be applied, Figure 1 represents an elevation with a part in section, of one end of i ,a washing machine equipped with automatic valve mechanism, automatic recording mechanism, and an electrical circuit including a signal. Fig. 2 represents the other end of a washing machine equipped with powertransmitting mechanism a discharge valve and automatic means for controlling rthe. same.

Fig. 13 represents a perspective view of portions of the mechanism for controlling the valve by which fluid is supplied.

The-same'referen'ce characters indicate the same parts-in all. thexfigures.' Referring first to the machine which 1s de scribed in my said co-pending application, it will serve to give a clear understanding of the present invention by briefly describing' said machine.-

In Figs. 1 and 2, represents the c lindrical casing or shell of a washing mac inc, said casing being mounted upon supports 16 and provlded with end bearings adapted to support the trunnions 17 of a rotatable contalner 18 arranged within the casing. For washing machines of this type it is customary to provide an inlet pipe 19 for water or other fluid, and a discharge valve 20'. It is also customary to provide mechanism for revolving or oscillating the container 18 within the casing 15. Without at temptingto describe in detail any particular form of power-transmitting mechanism,

it may be stated that the form shown includes a sleeve 21 for rotating one of the trunnions 17 a gear 22 whose hub is formed as a clutch member adapted to be cotiperatively engaged with a corresponding portion of the sleeve 21, a pinion 23 for driving the gear 22, a shaft 24 for the pinion, and pulleys 25 26 and 27 arranged upon the shaft 24,- Straightand crossed belts 28 and "29 are provided for cooperating with the pivotally mount (1 pulleys, one of which is loose, so as to drive the shaft 24;first in one direct-ion and then in the other. Any appropriate means may "be provided for shifting the belts to give the 'bell crank, and cam 37 carried by the gear 22. One end of the arm 35 is provided with a roll "38, and the arm is adapted to be oscillated-on its pivot 36 so as tovmove the roll toand from the ath of the cam 37'. When the roll is move into the path of the cam, 'the arm35 isdepressed by cooperation ofthe" cam with .the roll, and the bell crank is, thereby turned about its pivot-33 and motion is thus imparted to the lever 30 for retracting the clutch sleeve 21. 1

This circuit is shown by Fig. 1, and includes alsoa bell or other equivalent signal, a source 71 of current, a manually operative switch 72,-conductors 73 74 and 75 and an= automatic switch hereinafter described.

disk-or dial 84.0fany suitable material,for I receiving and recording the mark of the device 83. According to the present embod1- ment of the invention the disk is designed to record the successive operations of one working day, and the timing mechanism hereinafter described "is designed to,impart one complete revolution to the disk in twelve Q hours. The disk may therefore be conveniently. divided into twelve equal segments-each corresponding to one hour. "The hourly segments maybe conveniently subdivided into twelve equal segments each corresponding to a period of five minutes. The marking device 83 is mounted so as to be 'dead, that is, free from theinfluence of changes of temperature or other climatic I,

conditions. In performing its functions it remains in coiiperative engagement with the disk at all times, and in the course of twelve hours the disk will receive from the marking device a continuous line including 360 of a circle. L

For the purpose of recordlng successive operations of different characters, the dial may be. provided with concentric lines dividing the recording surface into concentric zones. To complete this arrangement, the marking device 83 is adapted to bemoved radially with'relation to the axis of rotatlon of the disk so that itsmarking pointmay be placed in any one ofsaid zones So long,

evice remains tinuous line represents the period during which the disk is rotatedwhllethe marking device remains stationary, and each radial line represents-the motlon of the marking device while being transferred .from one.

position toanother? .Mov ing of the marking device is accomplished manually, and the times of such changes are apparent by referring to the'radial dividing lines, whlch represent units of time. It willthusflbe seen that-the ;-operati0ns. recorded-by the. dial shown:jn3?1g..-9.include a :tenminute' period period of time Lisa for the firstoperation, a twenty-minute ten-minute period for the fourth operation,

said operations being repeated in the above order. Inasmuch as the radial divisions represent units of time and the eoncentrlc divisions represent operations of difierent characters, it is desirable to print the disk so as to indicate the values of the radial divisions and the significance of the concenspring for drivingthe same.

tric divisions. The dial is therefore illustrated with numerals indicating the hours of a working day and with words designating each concentric zone for an operation of one characterexclusively. The words designating the operations will of course be printed in accordancewith the requirements of the machine for which the device is desi' ed, and for a variety of combinations 0 which a machine is capable. i The disk is rotated in the direction indicated by the arrow in Fig. 9, and the means for mounting it is hereinafter described.

Referring now to Figs. 4 and '5, which illustrate an appropriate form of clock mechanism, 85 and 86 represent the pillar plates of a frame in which the clock mechanism is mounted." '87 represents the main gear of a clock train, and 88 represents the One end of the spring is attached to the stafl 89 and the other end is attached to a drum 90. The

gear 87 is aflixed to the drum but is loosely" mounted on the stafi 89, and is therefore rotated by the drum, and. not by the sta'fi'. The staff may be formed with a square end, as indicated by Fig. 4, for the purpose of receiving a key forwinding the spring. The main gear 87 drives a pinion 91 afiixed upon I the central arbor 79, which is driven at the rate of one revolution per hour. The arbor 79 carries two fixed gears 92'and 93, said gears beingof equal size, one for the purpose of driving the esca ement 94, and the other for the pur ose 0 driving the handle 78. The train '0 gears for transmitting motion from the gear '92 to the escapement 94' is illustrated by Fig. "5, and requires no' de tailed description. The. gear 93 drives a. pinion 95 afiixed upon an arbor 96, which is provided with another pinion 97- of equal size. The pinion 97 is arrangedupon the front side of. the plate 85 and is adapted to drive a. gear 98 of the same size 'as-- the gears 92 and :93. The .gear 98 is mounted. upon a boss 99 formed upon a lever 100 which is pivotedupon a pin 101 in the-plate 85. The pin 101 is slightly eccentric to the central arbor 79 and the boss 99 is formed with a slot .102 through'whi'ch the central arbor extends; Thelever 100 is adapted to be moved about the pivot 101 and to thereby carrythe gear 98 to: and from engagement with the pinion-97.

98 to the handle 78. The connection between the toothed disk and the handle 78 is shown in detail by Figs. 4, 6 and 7. Said connection includes an arm 104 loosely mounted upon the central arbor between the disk 103 andthe handle 78. The hubs of thehandle and the arm 104 extend through the front of-the casing 75, as shown by Fig. 4, and are connected in any suitable man ner so as tobe interlocked with each other. The form of connection illustrated includes cooperative interloclnng ortions on the two hubs and a collar 105 a xed upon the central arbor for preventing separation of the interlocked hubs. The free end of the arm 104 carries a rocking stud 106 at one end of which is an arm 107, and at the other end otwhich is a pawl 108. The arm 107 is afixed to the stud 10.6 but the pawl is loosely mounted on the stud. The pawl is provided with pins 109 which embrace the free end of a spring 110 of which the other end is allixed to stud 106. The pawl 108 is adapted to engage the teeth of the disk 103, but

is normally heldout of engagement by the action of the spring 111 on the arm 107' through the medium of the stud 106 and the spring 110. The arm 107 is further pro- .vided' with a pin 112 which is adapted to engage a nearly circular boss 113 formed upon the inner side of the front wall of the casing 75. The boss is formed with a-depression 114 in which the pin 112 may lie when the handle 78 is inthe position shown byFigs. land 4. The depression 114 is formed to prevent clockwise rotation of the handle 7 8,. but to permit counter-clockwise rotation. When the handle is moved away from this position, the'pin 112 in approach ing the concentric. rim of the boss- 113 turns the arm 107 against the tension of the spring 111 and thereby moves the engagement with the teeth 0 the disk 103. The teeth of the disk are preferably formed awl 108 into so as to permit motion ofthe pawl in either direction, but inasmuch as there-is no appre- 1s adapted torotate the armthrough the 00- The' means for transmitting motion from spring is inserted in an aperture inthe gear .tio'ndisk is held by the longitudinal expanthe gear :98 to the toothed-disk 1103 includes .a' friction' disk or washer 115 (see Fi 4) and a: helical spring 116. 'One end 0 the v sion of th spring-against a face of the disk; I

as to readily permit transverse movement of the clutch gear 98 and to maintain yielding driving relation with the disk 115.

Lever 100 is engaged by a spring 117 (Fig. 8) which tends to move the gear "98' mto engagement with the pinion 97. 'For the pur ose of placing the automatic switch under t e control of the washing machine herein illustrated, the lever 100 is connected m with the float 55 so as to be depressed when the float is depressed, and-to be released when the float is raised. The form of connect-ion shown by Figs. 1 and '8 includes a rod 118-forming an extensionof the float rod and passing through the free" end of the lever 100. The upper end of the rod 118 is provided with a head 119 by which the lever 100 is depressedwhen the that is in' its lower position. The timing mechanism is driven withoutinterruption and the handle 78 may remain stationary or be connected with the timing mechanlsm so as to be driven thereby according to the position of the lever 100. I 5 As hereinbefore stated, the central arbor 7 79 is driven at the rate of one revolution per hour. The handle 78 therefore, when coupled to the timing mechanism, is adapted to revolve at the same ratev of speed. The 30 front. of the casing 76 is provided with. a dial 120 with which the handle 78 is adapt ed to coiiperate in the same manner as the minute hand of a clock. The handle 78 when coupled with the timing mechanism is driven in a counter-clockwise direction, but the numerals on the dial'120 are arranged in clockwise order, according to their value.

- If it is desired to operate the machine for. a period of ten minutes, the automatic switch 40 may be manually adjusted to close the switch at the expiration of such eriod of time. The method of adjusting (t e switlch is to move the handle 78 in a counter-cockwise direction to a position registering with the number on the dial corresponding to the value of time required. When the handle I is thus moved, the pin.112 engages the concentric rim of the boss 113, thus moving the pawl 108 into engagement with the teeth of the disk 103. -The handle is thus operatively connected with the timing mechanism and is rotated thereby after being placed at the desired position. When the handle arrives at its former position after having comleted 'one revolution, it engages the contact 7 and thereby closes the circuit between tl e conductors 74 andx75. Assuming that the switch 72 is meanwhile in closed position, a-current is sent through the solenoid,

e0 41 and the solenoid operates as hereinbefore described to disconnect the-power-transmit- -ting mechanism and to open the discharge valve,20. The machine is thus brou ht to na-state of rest and the fluid in the casing 15 s5 is discharged and the? signal. =is operated,

thereby givin noticethat. the operation is completed. T e pin 112 after havin completed a revolution, isdrawn into t e depression 114 by the tension ofthe s ring 111, and the pawl 108 is'removed from'the teeth of the disk 103, thereby disconnecting the handle from the timing mechanism. The disk 103, however, continues to revolve by reason of its frictionalcontact with the s ring-driven disk 115. A s the level of the uid 1n the casing 15 falls, the float 55 likewise falls, thereby de ressing the. lever 100 against the tension 0 the spring117. The eccentricall mounted gear 98 is thereby disconnected rom the pinion 97, and rotation of the disk 103 ceases.

- It will be observed from the foregoing description that driving connection for the handle 78 depends first upon the position of the lever 100, and second upon the position of the pawl 108. "If the handle 78 is placed at the desired position before the float rises, it is not driven by the clock mechanism, because connection between the gear 98 and pinion 97 is not efi'ected until the rising of the float. Two things occur, therefore, simultaneously with the closing of the

supply valves

45 and 46. Y The first is the opening of the secondar valve 65, and the other is the clutching o the gear 98.

Recording mechanism.-It is hereinbefore explained how -the handle 78 of'thetime switch is driven at the rate of one revolution per hour. The disk 84 in order to be driven .at the rate of one revolution in twelve hours must be provided with appropriate gearing eqmvalentto the hour hand earingof a .clock movement. Gearing'of t is character is illustrated by Figs. 4 and 12. 121 represends a pinion aflixed upon the central arbor 79. The pinion drives a gear 122 mounted upon a stud 123. Afiixedto the gear 122 is a-pinion 124 which drives a gear 125.1oosely mounted on the central arbor. The ratio of the pinions and gears is such as to reduce the speed from twelve to one. The gear 125 is provided with a relatively long hub or sleeve on which the disk 84 may be mounted. Themeans here shown for attaching the disk comprises a plate 126 aflixed to the sleeve of the gear 125 and a plate 127 adapted to clamp the disk 84 against the plate 126. The plate 126 may bep'rovided with pins 128 and the disk 84 and plate 127' may be provided with apertures adapted to receive the pins 128, whereby the dlSk may be. positively locked in operative posit-ion. The outer end of the sleeve of the gear 125 may be provided with projections 129 adapted to confine a button 130 upon the sleeve. The.

button, as shown by Fig. 10,is formed with 25 139 is a hand wheel 140 by which the shaft passed over the projections 129. After placing a disk 84 upon the pins ofplate-126, the

plate 127 is placed in clamping position, a helical spring'133 is slipped over the sleeve, and the button 130 is passed over the projections 129 and given a slight rotary motion suflicient to move the notches of the aperture 131 out of register with the-projections 129.

The disk 84 may thus be detachably fastenedin operative position. I The marking device 83 is here shown as mounted at the upper end of a holder 134 arranged to slide in guides 135. Theholder is movable radially with relation to the central arbor 79, and in this embodiment of the invention is adapted to be moved manu-.

closed in a casing 138 which urnishes bearings for the shaft 139 upon which the pinion 13 is affixed. At one outer end of the shaft may e rotated. Figs. 1 and 3 show a pointer 1 11 aflixed to the hub oi the hand wheel 140 and adapted to cotiperate as an index with a scale 142 on the exterior of the casing 138. The shaft 139 may be provided with a cylinder'143 arranged within the easing 13,8 and provided with words or characters corresponding to the words or char- 'acters designating the concentric zones of the recording disk. The casing 138 is provided with a sight opening 144 for revealing I. one of the words or characters 'UPOIIMth inclosed cylinder. By means'of thls indicator the attendant may know in which zone the marking device 83 is placed.

145 represents a holder attached ,to the exterior of the casing 138, for the .purpose'of receiving one or more cards 146 upon which printed, directions maybe supplied. In

practice it is customary to provide the attendant with a formula of each operation by means of which the attendant is guided in determining the relative quantities of fluids and the periods'of time calculated to give the best results. If the printed instruct onsupon a card 146 are numbered in accordance with the scale 142 and in accordance with the indicator 143,'and the. arrangement of the designations of the several zones of the recording disk, the possibilities of errors on the partof the attendant are greatly reduced.

In operating the machine equipped with the hereinbefore desoribed recording; devices, it is the dutyof the attendant to prepare the machine for the succeeding operation immediately upon notification by the signal 70. If for any reason the attendant.

fails torespond when so notified, the recording devices .continue to record the lapse of time as a continuation of the preceding operation, and if it is found that the total lapse of time for any one'operation is materially in excess of the allotted. time, the failure of the attendant is shown upon the record.
