APPARATUS FOR RECORDlNG OUTPUT OF MACHINERY.

SPECIFICATION forming part of Letters Patent No. 571,110, dated November 10, 1896.

Application filed September 7, 1894. Serial No. 522,372. (No lllOdCLl To all whom, it; ntcty concern:

Be it known that I, PETER DILLON, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Apparatus for Recording the Output of Machinery, of which the following description, i connection with the accompanyingdrawings, is a specification, like letters on the drawings representing like parts.

It is frequently desirable in manufacturing plants to automatically record at some suitable point, as, for instance,in the office, the output or work performed by various machinesin the workrooms. Particularly isthi.

[5 true in. connection with the manufacture of paper wherein the paper-making machines are run night and day, it being a great desidera tum that the superintendent should in the morning be able to determine accurately the amount of work perform ed during his absence in the night.

In the manufacture of paper the paper-making machine is usually adjusted to produce paper of a specified weight per yard, and it 2 5 frequently happens that during the night or other time when the overseer or superintendent is absent, the workmen readjust the machine to cause it to make a heavier paper, so that the rolls of paper produced, while of the 0 required aggregate weight, are, nevertheless, short in the number of yards they contain. The workmen may also vary the operation of the machine to vary the output. \Vith these facts in mind, I have conducted experiments 5 in order to produce, if possible, an apparatus which would automatically record in the OlllGG the operations of the machines at all times. Such an apparatus to be intelligible and to show the superintendent exactly what had taken place during his absence should not only record the number of feet of web or paper produced by a machine per minute, but should also record the time and duration of various steps for the changing of wires and felts,

breakage of the web, .repairs, &c.

My experiments have resulted in an apparatus embodying the invention forming the subject of this application, which apparatus operates preferably through the medium of electricity, such being the most practical means for recording at a distant point the operations of anyinachine.

ln thepreiierred embodiment of my invention I providea receiver adapted to be located in the office, or at any other desired point at which the permanent record is to be made, and which contains a record in g-sheet, cooperating with which is suitable recording mechanism for recording not only the output of the machine, but also the times and duration of the stops, the sheet for the best results bein made movable by suitable clockwork.

The movements of the recording mechanism in the apparatus here selected to illustrate my invention are controlled by two sets of electromagnets, one set in circuit with a circuit-chan gin g device connected in suitable manner with the machine in the mill and adapted to change the condition of the cireuit periodically or upon the completion of certain specified number of feet or other quantity of the output of the machine, the other of said receiving-magnets being electrically connected with a second circuit-changing device actuated only when the machine is stopped.

In applying the apparatus to paper-makin g machinery I prefer to arrange a roll in contact with the web of paper as it leaves the machine, which roll at the end of every predetermined number of rotations, indicating a certain number of feet of paper produced, actuates the circuit-changing device referred to to make the required record at the distant receiver. 8"

In the drawings, Figure 1 represents one form of transmitting device adapted to be connected with the machine in the shop or mill, the face-plate of said device being removed to expose the working parts within. 0 Fig. i is a view looking at the side of a portion of the mechanism shown in Fig. 1; Fig.

3, a face view partially broken away of one form of receiver; Fig. 4:, a side view of the same, partially broken out; and Fig. 5, a view 5 illustrating the preferred type of dial or recording-sheet from which the work of the machine is read.

The drawings illustrate the preferred construction of apparatus embodying myinven- 10o tion, though it should be understood that my invention is not restricted to the particular apparatus shown.

Referring to the drawings, Fig. 1, A represents an inclosing shell adapted to be arranged in close proximity to the machine the output of which. is to be recorded, said shell havingsuitable bearin for the prime or 1110- tor worm-shaft (I, having a worm a, working in a wormwheel Fig. 2, loose on a shaft (1, journaled in suitable bearings in the said shell, said worm-wheel (t having a hub on which is cut a pinion (r in mesh with and driving a larger toothed wheel a, loosely mounted upon a shaft d,the hub of said wheel a being provided with a pinion geared to a larger wheel (i The hub of the wheel a is shown provided with a cam (1, having a shoulder or drop 4. (See Fig. 1.) Resting upon and in contact with this cam a is one arm l) of the L-shaped circuit-changing device 13, pivoted at Z) and having its other arm fitted with an electrical contact 11 adapted to cooperate with the spring-contact L attached to the bindingscrew l)" for proper change in the condition of an electric circuit, as will be hereinafter described. The circuitchanger B has its pivot I) also preferably connected with a binding-screw U, as shown.

In practice the worm-shaft a is connected in suitable manner with some moving part of the machine, the said shaft, where the appz'tratus is used in connection with a papermalcing or other similar machine, being preferably connected with a roller, as, for in stance,the spring-roller,in contact with which the completed paper runs in leaving the machine, a certain specified number of rotations of the roller represcntin g a certain number of feet of paper delivered from the machine. The cam is therefore rotated slowly, the circuit-changer B riding upon the cam-sun face,and when it reaches the shoulder 4C in the cam drops, and thereby, through its contact IF, closes an electric circuit through the spring 0 the said circuit-changer being atonce raised slightly by the cam, as shown, to again break the circuit, so that an.electric impulse is sent over the circuit at the end of every predetermined number of rotations of the worm-shaft a, which shaft constitutes one form of prime actuator for the apparatus.

In the apparatus shown the worm-shaft a is provided at its inner end with a bevel-gear a in mesh with and driving a mating-gear a on a vertical shaft 0,;journaled in suitable bearings c in the inclosing shell. Fast on this shaft 0 is a hub c to which are pivoted at c the swinging governor-weights c, connected by links c with the vertically-movable sleeve 0, surrounding the said shaft 0, a spring c tending to press the said sleeve normally down into its lowermost position with the govern orweights also in their lowermost position nearest their axis of rotation. Immediately beneath the flanged bottom of the sleeve 0 I have arranged a bell-crank circuit-chairgingdevice (1, pivoted at d to a part of a bindingpost (1 and having a spring (1 to retain it normally in its elevated full-line position, Fig. 1. The circuit-changing device (6 has a contact (1", adapted to cooperate with the spring-contact d on the binding-posttl. Rotation of the worm-shaft a causes corresponding rotation of the shaft 0 and the governor-weights c, which, by centrifugal force, move to a greater orless distance fromtheir axis,'according to the speed of rotation, and should rotation of the wornrshaft to cease because of the stopping of the machine for any reason. the said governor-weights will immediately drop to their lowermostposition, causing the sleeve c to be pushed downwardly and, acting through the circuit-changin device (Z, close an. electric circuit between the two contacting or binding posts (Z d", for a purpose to be described. The shaft 0, with its governorweights, operating as shown constitutes one form of stop-indicator, that is, said shaft and weights act to indicate the stopping of the machine for any reason.

Referring now to Sheet 2, E is one .form of receiver, the same, as shown, consisting of an inclosing shell 6, in which is journaled the shaft c, carrying at its front end a dial-plate 6 adapted to receive and carry a paper or other recording dial or sheet m, the latter being retained in position upon the plate 0 by a suitable annular holding-ring c. The dialplate is provided with a circular groove c to enable the sheet applied to the plate to be punctured by a suitable needle-point, as will be described. The shaft 6, with its dial-plate and recording-sheet, is rotated, preferably once in twenty-four hours, by suitable cloclr. mechanism contained in the upper part of the iuclosiug shell, the minute and hour hands a e for the said clock mechanism being shown at the face, Fig. 3.

The measuring recorder arm f, herein shown as carrying the prick or needle-point f, is fast upon a shaft f journaled in a suitable lugf on the outside of th shell c, said. shaft at its end opposite the arm fhaving a crank f (see dotted lines, Fig. -.t,) to which is jointed one end of thelinlcf, jointedv at its opposite ends to the lever f, pivoted at f (See Fig. This lever f, as shown, has a detent f, which rests always in one of the notches in a ratchet-wlieelf mounted upon a shaft f, journaled in suitable bearings within the inclosing shell. Mounted loosely upon the shaft f is an L-shaped armatureoarrying leverf having one of itsarms fitted with an armature f cooperating with the receiver-magnet f, the other arm of said lever having pivoted to it at f an operating-pawl f which. latter cooperates with the teeth on the wheel f, a spring f retaining the said armature-lever normally in its retracted position.

The magnet f is connected in circuit by wires 25 20 with the circuit-changing device ITO B in the transmitter A of the apparatus, so

that whenever the circuit is closed by the cir-v cuit-changing device 13, indicating the completion of a certain predetermined number of yards of the web or other specified quantity of work produced, such closure of the circuit will energize the magnet f, causing it to attract its armature and through its pawl f to rotate its ratchet-wheel f 10 through a distance of one tooth, which movement causes the detent f and its lever f to ride over the crown of one of the teeth of the said wheel and to drop down again into the next succeeding notch, such rise of the detent-lever f causing the needle-point) on the marker to puncture the recording-sheet, as best illustrated in the detail, Fig. 5, thus indicating upon the said sheet and with relation to the hour and minute divisions thereupon the precise time of completion of the specified number of yards or quantity of output.

The stop-recorder arm is shown at h, the same at its free end being provided preferably with a marking pencil or pen 7L and at its opposite end pivoted at h the same intermediate its length having jointed to itone end of a link its, at its opposite end jointed to the armature-lever h pivoted at h and provided with the armature h, cooperating with the receiver-magnet 717, a spring h retaining the said armature normally in its retracted position.

The receiver-magnet h7 is connected in circuit by branches from the wire 26 and by the wire 27 with the circuit-changing device at of the transmitter, closure of the circuit by the latter on the stopping of the machine acting to energize the magnet h and cause the latter to attract its armature and thereby draw down into its dotted position the marker h to leave a record upon the recording-sheet, such as illustrated in Fig. 5. The wire 26 is common to the circuits for both magnets f and 777, it having branches leading to the magnets and to their respective circuit-changing devices.

Referring noW to Fig. 5, I have illustrated the preferred form of dial or recording-sheet and have indicated thereon a typical record, such as would be made upon the same by a twenty-four hours run of a paper-making machine. Referring to the said figure, the dial or recording-sheet m is shown as provided at its periphery with division lines m suitably marked to indicate the twenty-four hours of the day, each hour-division being subdivided by other lines to indicate minutes, seconds, 850. The dots or punctures m represent the punctures made by the measuring marker or needle f during the twentyfour hours rotation of the recording-sheet, and by noting the varying distances between successive punctures the various periods of time consumed in running off the specified number of yards between one puncture and another may be deter mined. For instance, assuming that the ma chine is adjusted to produce sixhundred yards of paper of a specified weight for each complete rotation of the cam a, that is, six hundred yards between each two punctures upon the sh eet, by reference to Fig. 5,between the hours twenty-four and one, it will be seen that there are seven punctures, indicating that in that hour four thousand two hundred yards and afraction over were produced by the machine, whereas, referring to the hour nineteen to twenty, it will be seen that there are only four punctures, indicating that only two thousand four hundred yards were produced during that hour, which would show the superintendent that the workmen had readjusted, or stopped, or slowed down the machine so that it had not produced the maximum quantity of paper. It will thus be seen that the production of the machine for any hour or fraction thereof during the day or night is permanently recorded upon the recording-sheet. \Vithin the series of punctures 771 will be seen an unbroken line,marked 01, made by the marker h to show the times and duration of the various stops. lVhen, for instance, the paper or web breaks, the stop device at the transmitter will act to close the circuit through the circuit-changing device d, and will thereby energize the magnet h and cause its marker h to be drawn down toward the axis of the recording-sheet carrier E and make a short radial mark, such, for instance, as shown at 01, showing that the machine had stopped or the web broken, and the line being a single line would indicate that the machine had been again started up or the web brought over again before the sheet had moved any perceptible distance in its travel. Should the machine require new wires, however, it would necessarily require the machine to be stopped for a considerable time, and in that case a break, such as indicated at M, would be made upon the sheet, the length of the break indicating the number of hours or fraction thereof during which the machine was stopped.

The record is simply and clearly made and in such manner as to be quickly grasped by the one in charge, and it requires the simplest form of mechanism.

1 am aware that various apparatus have been devised for permanently recording upon a rotating sheet, by means of a marker moving out and in with relation to various circles upon the dial, variations in speed of rotating bodies; but so far as I am aware I am the first to indicate upon a recording sheet the completion of certain predetermined quantities of work or web produced by suitable marks or impressions made with relation to hour and minute divisions or other characters to indicate the times at which the marks or impressions were made, and, fur ther, to provide a stop-recording mechanism to indicate the times and duration of various stops.

The construction of apparatus herein shown and described is simple and efficient, and, as

before stated,I prefer to operate the same through the medium of electricity, though I desire it to be understood that my invention is not necessarily limited to the particular construction of apparatus shown, nor is it restricted to use in connection with papermaking or any other particular type of machine, for it is evident that my invention embodied in suitable mechanism suggested to those skilled in the art maybe adapted for recording the operations of various machines or machinery.
