, This invention relates to a recorder such includes a motor driven dial or record sheet 7 which can be used-.for a long eriod of time without requiring' the insertlon of a new record sheet in theapparatus. More specifically considered, the invention aims to provide means whereby a recording dial or record sheet which makes one complete revolution in a given time, such as twenty-four hours, may be employed for a considerably longer period of time, such as seven days,

without causing the record made on one day to be confused with,'or -to-i nterfere at all with the record made-0 11 any succeeding day.

asconsisting in certaln novel details of construction and combinations and arrangements of parts which will be described in the specification and set forth in the appended claims.

In the accompanying sheets of drawings Thave shown my invention as embodied in awater level recorder, and in the drawings Figure 1 is a front View of the recorder with a portion of the base. or magnet'casing broken away tos how the actuating magnets which actuate the pens or markers; Fig. ,2 is a rear elevation, with the rear plate removed; Fig. 3 is a vertical sectional view on an enlarged scale; Fig. a is a horizontal sectional view through the magnet casing, showing the actuating magnets and the counterweighted markers; and Fig. 5 is a perspective view of the lower portions of adjacent markers showing how the counterweights are disposed so that one of the markers will normally engage the'dial or marking sheet, and the other marker will The invention may be briefly summarized L/ gorlmally be out of engagement with the 1a s V M The recorder includes an annular or cylindrical shaped casing 10, provided with a glass front 11 connected to the casing by a h1nge 12 so that the recorder can be vlewed from the front, and permitting the front part of the casing to be opened so that the dlal or record sheets may be inserted or removed, and the marking pens (if inkreccords are made) can 'be cleaned or refilled with ink. The casing 10 is also provided with a rear door or wall'1'3, normally held in position by screws 14, which can be removed so as to permit access to the motor or to the electric connections or conductor wires within the casing.

Between the front and .rear ends of the casing. there is a stationary disk 15, preferably of metal, against which is lightly pressed by fingers 15*, one of which is shown 1n Fig. 3, a dial or circular record sheet 16, which is designed to be rotated and preferably to be given a complete rotation in twenty-four hours by a spring motor or clock 17, which is provided with a spindle 18 which projects forwardly through the face of the plate 15. The manner in whichthe motor 17 is supported and "adjusted will be explained subsequently.

The dial or record sheet-16 1s provided with equally spaced time lines 16 which preferably divide the sheet intotwenty-four spaces, these lines being arc-shaped, and if extended inwardly, would pass through the center of the sheet. Preferably also, the spaces between the lines 16 is divided into subdivisions of time by additional evenly spaced time lines, all of which may for convenience be termed isotempo lines. Additionally the sheet is divided by concentric, evenly spaced circles 16 into spaces or division's, which in this instance indicate different water levels of the boiler with which the recorder is employed.

For the purpose of making a record on the sheet 16, I employ markers, which in this instance, although not necessarily, make ink lines on the sheet and consist of pens 22 which are supported on the upper ends of light and somewhat flexible fingers 23 which extend downwardly from the dial easing into a magnet casing 24 which constitutes a hollow column for the upper part of the recorder and is mounted on a base 25. At the lower ends, the fingers 23 areprovided with counterweighted heads which are pivotally mounted on a pin or spindle 26 (see Figs. 1, 3 and 4 The arrangement of these counterweighted heads of the markers and of the magnets which actuate them is important, because when the recorder is used for a certain pur-' pose, such, for example, as the recording of the water level in a boiler, it is desirable in order that good and easily readable records may be made-that part of the markers normally engage the record sheet, and at intervals, or on the occurrence of predetermined conditions be lifted therefrom so as to normally mark the record and when lifted from the sheet to leave a break in the mark or' line, and that other markers be normally out of engagement with the record sheet, and at intervals, or on the occurrence of other predetermined conditions be drawn forward into engagement with the record sheet so as to make marks or lines thereon. In this instance, the innermost and the outermost markers, that is to say, the marker which indicates or records the lowest water condition, and the one which indicates or records the highest water condition are normally out of engagement with the record sheet, and when the water reaches either the predetermined low level or when it reaches the predetermined high level, one of these two markers is drawn into engagement with the record sheet. On the other hand, the intermediate markers, or those which record intermediate water levels normally engage and draw lines on the record sheet, and whenthewater level reaches a position corresponding to one of these markers, that marker is drawn from the record sheet so as to leave a space or a break in the line which it normally marks or draws.

v In other words, the water level record on any sheet is read by the breaks or spaces in the lines except for high and low water conditions which are read by the marks or lines themselves.

This is done because the high and low level conditions are maintained usually for very brief periods.- For example, the low level condition would be recorded frequently by the fireman blowing out his gage glass, which a careful fireman does at regular periods. It has been found by experience that if it is attempted to record the time of blowing out or cleaning the gage glass by lifting a en from the record sheet, it would be difiicu t, if not impossible to determine when because the pen would be rerecord-sheet so quickly after this was done, stored onto the it was lifted that it would not leave, in many instances, a discernible break in the line. On the other hand, if the pen is normally out of engagement with the paper and comes in contact therewith only for a short time, the time of blowing out the gage glass is clearly recorded.

With this explanation, reference will again be had to the construction of the markers, and by referring to the drawings it will be observed that the four intermediate markers are provided with heads 27' with counterweighting or counterbalancing rearward extensions which press the pens of these intermediate markers against the record sheet with just sufiicient pressure to make good lines or marks thereon. On the other hand, the innermost and the outermost markers are provided with heads 28 which have forward counterweighting or counterbalanclng extensions which tend to swing the innermost and the outermost markers outwardly away from the record sheet.

These markers are shifted away from their normal positions by magnets, four of which, designated 29, are in the front part of the magnet casing 24, and are provided with armatures 30 having extensions 30, which when the several magnets are energized, rock the markers so as to move the pens away from the record sheet and thus actuated by magnets 31 having armatures 32 which as will be observed by reference to the drawings, tip these two markers in the reverse direction so as to cause the pens to engage the record sheet. It will be understood, ofrcourse, that these magnets will be energized separately, or one at a time, the particular magnet which is energized depending upon the level of the water in the boiler or gage glass. It will be understood also, that when the head of the marker is released by the corresponding magnet armature, said in gnet will drop back to normal position by gravity.

It may be stated at this point that there will be employed with this recorder, a battery or othervsource of current and a series of electric contacts associated in some manner with the boiler, as with the gage glass, and there will be utilized a float controlled contact maker which will rise and fall with the change of water level and engage the several contacts so as to complete the circuit separately through the several magnets. I prefer to employ in connection with the recorder here described, the float controlling mechanism illustrated and claimed in my prior Patent No. 1,179,486, granted on the 18th day of April, 1916.

It should be observed in passing, that the pens 22 ofthe markers are arranged in an are of a circle correspondin to the curved isotempo lines as shown in ig.'1.

An additional important feature of my invention resides in the manner of mounting and adjusting the motor and the record sheet so as to adapt it for a longer period of time thanis represented by a complete revolution of the record sheet. For an understanding of this feature reference is had particularly to Figs. 2 and 3-. It will be observed by referring to these figures that the motor 17 which rotates the record sheet is mounted in a ring or circular head33 which has a laterally projecting arm 34, pivoted at 35 to a bracket 36 near the periphery of the casing 10. Diametrically opposite from the arm 34 there is a guide 37 for the clock holding ring or head 33. For the purpose of shift ing the clock and hence the recording sheet, there is provided a shifting spindle 38, which at its lower end is threaded and engages a nut 39 rather loosely, mounted in a boss or chamber 40 carried by the clock supporting ring or head 33. The outer portion of the bolt 38 extends through the annular casing wall 10, and at its outer end is provided with a small hand wheel 41 which may be turned to swing the clock about the pivot point 35. Associated with this hand wheel 41 is a spring actuated looking pin 42 with a point which is adapted to enter into an opening in a. lug on the lower side of the hand wheel 41.

The object of this arrangement or construction is believed to be now apparent.

' It will be apparent that when a twenty-four hour record has been made, instead of placing a new record sheet the recorder,

the operator simply pulls out the locking pin 42 and turns the motor shifting spindle or bolt 38 through one revolution, the pin being then allowed to snap back into locking position. This swings the motor and the record sheet a short distance to the left or right as the case maybe, so that the pens will be displaced from the record lines which they made in the preceding twenty-four hours. This can be done repeatedly, the

pens each day making records independ-' ently of those made on the preceding day or days. In practice, I find that a seven day record can be conveniently made on a record sheet which makes a complete revolution each twenty-four hours. It might be stated that the stationary dial plate 15 contains an elongated slot 15 (shown by dotted lines in Fig. 1) through which slot project the turning spindle for the record sheet, andthe disk 21 against which the sheet is pressed by the-holding disk 19.

In order that accurate records may be made from day to day it is important that the clock be shifted in a predetermined direction with respect to the isotempo lines, or with respect to the curved hne formed 'by the several marking pens. To this end the pivotal axis 35 about which the clock is turned or swung, is the center of the arc of the several pens, or the center of the 'isotempo line when arranged directly under high and low water conditions are reached.

The connections for the several magnets will be made by binding posts 47 arranged in a binding post chamber 48 which is mounted on the base 25, and the connections with the alarm bells and lamps will be made to the magnets which actuate the high andlow water recording pens by conductors 49 which are indicated in Fig. 2.

While I have described the preferred construction of the recorder and have explained the preferred use to which the recorder may be put, I do not wish tobe confined either to the details of construction herein disclosed, or to .a recorder used for indicating water level conditions of a boiler, as the construction may be modified without departing from the broad principles of the invention, and I am aware that the essential features of the recorder may be used for other purposes than that herein mentioned.
