vices, andhas'for its :object the arrangement and construction of a' periodic recordmg device making a printed record of the position of some body, as, for instance, a-oat upon the surface of'a liquid.' Vhen arrangedwith such` float, it becomes an eiii cient water-stage recorder, and I illustrate and describe the device in thisconnection, but call attention to the fact -that the device is capable of recordingl the successive positions of any moving body that might be substituted for the float above mentioned.

The general principle upon which the device operates is as follows: A suitable clock continuously, a type-wheel, carrying dies, or types, adapted to rint time at successive intervals of; say, fi teen minutes. At the termination of each o'f these time-intervals, the clock closes an electric circuit and causes a hammer or platen to be thrown against the type-wheel, for Vthe purpose of prmting upon an interposed ri bon of paper fed'along with the time type-wheel. Adjacent to this time type wheel 1s a second type-wheel, operatively connected to move -with a float or other object, so as to bring to the printing-point appropriate types or dies to indicate the position of the float or other object. This type-wheel is struck by the same hammer or platen, and prints-on the same paper ribbon, so that a simultaneous record is taken of time and stage. As the ribbon is fed along with the type-wheel, and as the distance between successive dies is small, a simple feed and economy in the use of tape are secured.

I shall describe the preferred embodiment of the device in connection with the accompanying drawings, wherein:

Fi ure 1 is a frontelevation of the assemb ed device, the front portion of the case being removed and the batteries omitted; Fig. 2 is a side elevation partly sectional, of the apparatus shown in F ig. 1, the plane of sectlon being on the center-line of the device; Fig. 3 is an elevat-ion of a fragment of the printing-wheels and hammer; Figyll is a s1de elevation of the printing-wheels, as shown in Eig. 3; Fig. 5 is a. section on the line 5 5 of Fig. 3; and Fig. 6 is a section on the line 6 6 of Fig. 2; F ig. 7 is a detail elevation of the parts comprising the periodic circuit-closing device and the battery wiring, etc.; and Fig. 8 repl'resents a portion of the record tape, showg ing'practically constant water-stage.

' -Llke numerals refer to like parts throughout.

The apparatus is supported in 'a frame or easel, usually of wood.

2 is a clock, having the usual dial 3 and handsV 45.v The movement of this clock is similarv in all 'respects to the ordinary striking' clock movement, the clock being arranged `to strike vone stroke at regular timeintervals, say, on eachquarter-hour. This striking mechanism is used as a circuit-closer. The metal clock-frame 5 is connected through 'binding-post 6 and wires 7 (sec Fig. 7) to one terminal of an electric battery 8, carried in a swinging block or bracket 9, pivoted to the frame V1,on a pin or bolt 9a. This connects the bell-hammer l0 to one of the battery terminals. lIn the path of backward movement of the hammer is a light leaf spring 11, carried by bindingpost l2 and connected by wires 13 through an electromagnet 14, t0 the other terminal of the battery. As the binding post 12 is insulated from frame 5, the contact Vof hammer 10 with spring 11 completes a circuit through the battery 8, its connections and the electroanagnet 14, energizing the latter. Thus, the magnet is periodically energized for a short time at regular intervals, the purpose in using the rearward movement of the hammer to effect such energization, being that its motion is then at its slowest, so that a good Contact can be secured.

Projecting rearwardly from the clock is an extension 15 of the shaft upon which the hourdiand is mounted. Concentric and in line with this is a shaft 16, carried on the frame 1, and loosely mounted on this shaft 16 are two typewheels 17 and 18. The wheel 18 is mounted on roller-bearings 19, and is connected by means of a sleeve 20 and pins 21 tothe extension 15. Consequently, it revolves with the hour-shaft of the clock.

The wheel 17 is mounted on plain bearings and carries a gear 2Q, attached thereto by screws 22, said gear meshing with a pinion 23, loose on stub-axle Qfl, carried by frame 1. IP ast to pinion 23, is a sprocket 25, over which runs a chain 26 carrying at one end a float 2', and at the other a counterweight QS, to keep the chain taut. As the lloat Q7 rises and falls with the waterlevel, sprocket 25 will be rotated in one or the other direction, and wheel 17 Will be turned through the gear-train to a corresponding position.

theel 17 carries types 29, appropriately spaced and bearing the proper numerals or legends to record at the printing-point the various positions of ioat 27. lVheel 18 carries types adapted to record at the printing point the times in hours and minutes corresponding to the positions of the hour-hand at the various time-intervals marked by the closing of the circuit. These Wheels 17 and 1S carry, respectively, ribs 31 and 32, adapted to guide and retain a tape 33 over the type-faces.

rlhe type-Wheel 13 is provided With a series of very ne needle points 18, projecting beyond itsperiphery so as to penetrate the record tape 33 (as at 1S, Fig. 8), and cause it to move with the type-wheel. The diameter over the type faces on `Wheel-18 may be made slightly larger than the similar measurement on Wheel 17, so that the latter may rotate free of the tape.

rl`he ribbon 33 is made up of two strips, the record strip 3i and a carbon paper ribbon 35, or pigmentcarrier to give the necessary mark When the ribbon is struck against the type-Wheels. These two strips are wound together on a spool 3G, whence they pass up around the type-wheels and down to a second spool 37. This spool 37 is urged in its winding direction by a weight 38, hung on a cord 39, wound around a drum 110. Connection between the spool 37 and drum 40 is had through a train of gears Lt1 and a2. The purpose of this driving mechanism is merely to keep the ribbon taut and take the load ofi' the clock mechanism, the real feed of the paper being effected by the time type- Wheel 1S.

From the above description it is obvious that the proper time type is brought to printing position at the end of each timeinterval. At such moment the electric circuit is completed and energizing the magnetcauses an impression to be taken on the tape of this time die and the nearest die on the stage type-Wheel, through the following instrumentalities 43 is a bracket carried on frame 1. A short arm 44, of a bell-crank lever pivoted in this bracket, carries an armature 45 adjacent the pole of magnet 14, so as to be drawn down when the magnet is energized. The

long arm 4.-(3 of this lever carries a rubber platen 4-7 and a pin 4S. IVhen the arm 4d is drawn down, platen 47 is thrown against the type-wheel, making a record on the ribbon. Iin L18 punctures the paper and accurately indicates the stage, as the platen is apt to cause a series of two or more dies to print because of their closeness on the stage type-wheel. This is clearly indicated in Fig. 8, Where the simultaneous printing of several dies is illustrated. The perforation 49 indicates exactly Which reading is the one to be taken as corresponding to the time printed by the time-Wheel.

It will be noted that the record shown in Fig. 8 indicates no substantial change in the Water-stage.

The idea of driving the ribbon constant-ly and by means of the time type-Wheel is important, as simplifying the mechanism and economizing space; also, because if a record is missed, the blank space in the record ribbon will, undoubtedly, call attention to the fact.

Then the recorder is positioned, it is necessary to `so 'adjust the stage type-wheel that itshall print the correct designation for the position of the float.' To accomplish this purpose it is merely necessary to lift the chain from the sprocket Wheel, and turn the type-Wheel to the position corresponding to the water stage. -The chain is t ien placed over the sprocket Wheel, and the record printed, will thereafter be directreading without correction or computation of any sort.

In the following claims I shall use the words printing and type in the broad sense, as indicating any method or means for printing, embossing, perforating or otherwise forming upon the record strip leglble characters, and l shall use the term printed record to indicate a record made as above, as contradistinguished from a continuous record, the latter being a record traced by a stylus andindicating quantity or other conditions by the length of the line so traced, or by its height above a base line, or by similar characteristics lof the line, as is common in recording devices.
