RECORDING WATER-GAG E.

SPECIFIJATION forming part of Letters Patent No. 681,536, dated August 27, 1901. Application filed August 25, 1900. Serial No. 28,035. (N0 modem To aZZ whom it may concern.-

Be it known that I, JULIEN P. FRIEZ, a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Recording ater-Gages;- and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to watergages for measuring and recording variations in the depth of liquids either still or flowing, and particularly in the variation of thedepth of the flowing contents of rivers, irrigatingditches and sewers, reservoirs, and also of tide Water.

Its objects are to increase the efficiency of such gages and to insure convenience and safety both in use and in transportation.

The invention consists in the construction herein described and pointed out.

In the accompanying drawings, Figure l is a perspective of the improved recording watergage. Fig. 2 is a partial perspective of a cover therefor. Fig. 3 is an end elevation, the cover being denoted by broken lines. Fig. 4c is a perspective of a pen-stock carrier. Fig. 5 is a partial section showing the connection of the pen-stock with its carrier. Fig. 6 is a partial side elevation of the carrier and pen-stock. Fig. 7 is a perspective of a pen.

Fig. 8 is a perspective of a detail of the pen- Fig. 9 is a longitudinal sec-I tion of the gage, a clock-mechanism case be- Fig. 10 includes perstock carrier.

in'g shown in full lines. spectives of the details of a spring-held bearing for a cylinder-journal. Fig. 11 includes perspectives of the bearing for the pen-stockcarrier screw-rod and its coacting guide-rod. Figs. 12 and 13 are respectively edge and.

side elevations of a pencil-holder and holdercarrier. Fig. lat is a view showing a clutch to connect the recording-cylinder and one of its journals. Fig. 15 is a side elevation of a detail.

In general the instrument comprises clock mechanism, a pen or pencil regularly moved by the clock, and a record-sheet supported on a-cylinder rotatably moved about its axis in either direction by a counterbalanced float.

Numeral 1. denotes a base, and 2 the clockcase.

3 denotes a screw-threaded rod having journals in a post 4 and in the clock-case and uniformly rotated byany suitable mechanism in the case, being in the present case driven by a gear 2, meshing with a gear 3 fixed on the rod.

5 denotes a pen, 6 a pen-stock, and 7 a penstock carrier. The pen-stock carrier comprises a part 8, preferably tubular, having a loose or sliding connection with rod 3. It also has a like connection with a guide-rod 9. Between ears 10, fixed to the sliding part of the carrier, is pivoted a section 11, suitably threaded to engage the threads of the rotating screw-rod 3. The threaded carrier-section 11 is held to its work bya spring 12, connecting a stud 13 on the section with a stud 14 on the extension 15, forming part of the carrier 8. The threaded section 11 of the carrier can be disengaged from rod 3 by depressing the arm 16, whereupon the pen-stock carrier can be freely moved lengthwise the rod for resetting or other purposes.

16 denotes an interval in the threads of rod 3 to provide for the automatic arrest of the movement of the carrier lengthwise the rod by breaking its operative connection with said rod, and thus mediately breaking its con-' nection with the clockwork. This interval is a little longer than the screw-threaded portion of the section 11, (see Figs. 8, 6, and 4,) which section comprises the sole thread connection of the carrier and rod, so that when said section is adjacent the interval the parts are not operativel y connected and the carrier rests, though the motor continues to run. This avoids injury to the apparatus, which would otherwise occur if the observer failed to stop or reset the devices before the motor forced the tube 8 of the carrier against part i. Since the operative connection of section 11 and rod 3 can be broken at will by depressing the arm 16, thereby turning section 11 about its pivot 11 the construction provides for the convenient and easy adjustment of the pen-carrier lengthwise the cylinder, and since devices to be described provide for the adjustment of the cylinder and recordsheet circumferentiall y the record can be made to start from any desired point on the sheet as required under various conditions.

It has heretofore been proposed to continuously rotate a cylinder and intermittently move lengthwise the same by means of afloat and weight. Myimprovement contemplates an operation continued without inspection for a definite period and then automatically arrested, as is desirable in case the instrument is not inspected or reset at the termination of said period. As the pen is continuously moved until it is arrested, injury might and would result were no means provided for disconnecting it from its motor. It is incidental to the improved construction that the diameter of the recording-cylinder and of its case may be considerably reduced without diminishing the capacity of the instrument.

The pen-stock is supported on a vertical part or post 17 of the carrier extension by means of a disk 18, connected thereto by a screw 19. A three-armed spring having a central hole 20 to receive the screw 19 is held on a stud 21 of the disk and bears on the head of the post. By these means the penstock is held yieldingly in a vertical plane. 23 denotes a similar connection between a disk 25 of the pen-stock and ahorizontal disk 24, fixed to disk 18. This provides for a horizontal adjustment of the pen-stock, which is held in a yielding manner upon the disk 24.

The rods 3 and 9, with the pen-stock carrier, can be detached from the machine by removing the screw 25 which holds the bar 26 upon the top of the post 4, whereupon the rods can be withdrawn from their bearing in the clock-case and also from the carrier, the rods being loosely supported in the clockcase for that purpose. The parts are assembled by a reverse operation.

In Figs. 12 and 13 is shown a pencil holder and carrier which may be substituted for the pen-stock and carrier when desired. The holder 27 is pivotally supported on a carrierpost 28 between suitable cars.

29 denotes a spring to hold the pencil to its work, and 30 is a nut to adjust the tension of the spring.

The cylinder 31, which carries the recordsheet 32, is moved back and forth byacounterbalanced float 33 to carry the sheet under the pen constantly moved parallel to its axis. The axis of this cylinder has hearings in a part fixed to the clock-case and in posts 34 and 35.

36 denotes a float-counterbalancing weight, and 37 a perforated metal band having one end secured to the float and the other to the weight. The band is operatively connected to a sprocket-wheel 38, having pins 39, suitably engaging holes 40 in the band. Cords and driving-pulleys are objectionable, for the reason that the cords expand and contract with variations of moisture and sprocketchains are rendered inexact by wear if not so made at first. Said sprocket-wheel has its shaft 43 journaled in small bracket posts or studs 41 and in the intermediate post 35. This provision against contraction and expansion of the driving connection and against slip is especially important in an apparatus requiring accurate work and exposed to moisture. Power is transmitted by means of a pinion 42 on shaft 43 of the wheel 38. Said pinion drives a spur gear-wheel 44, fixed on the shaft 45.

46 denotes a larger sprocket-wheel, which may be used instead of the wheel 38, if required. As represented in this case, its diameter equals that of the cylinder, but it may be given any desired diameter.

47 denotes slots in the base for the free passage of the perforated band which operatively connects the float, weight, and wheel.

48 denotes pulleys employed to spread and guide the band when the small sprocketwheel is used. To enable said Wheel to be easily disconnected from the gear-wheel 44, the shaft is supported to slide endwise in its bearings to throw the pinion 42 out of mesh with the wheel 44. A pivoted stop to hold said sliding shaft when adjusted is denoted by 49.

49 indicates a spring to hold the stop engaged in a groove 43 when pinion 42 is slid out of mesh with wheel 44. Said groove is indicated at the left of Fig. 9. In said figure the stop 49 is shown covering the end of shaft 43 and holding pinion 42 engaged with gear 44.

The shaft is detachably connected to the cylinder 31 by transverse arms having pins 51, adapted to engage holes 52 in a disk 53. This disk has a screw-threaded stud 55, and the disk is held against the cylinder-head by a nut screwing on the inner end of the stud within the cylinder. This nut holds an armed spring 54 adjustably against the inner face of the cylinder-head, the spring-arms bearing on said head, and the whole providing a detachable connection between the cylinder and the shaft 45.

56 is a spring to hold the pins 51 of the shaftarms 45 engaged with suitable holes in the disk 53, and 57 is a screw-stop whereby the pressure of the spring can be varied and limited. This constitutes an efficient and easilymanipulated spring-held clutch. The pins can be disengaged from the openings and moved away from the disk 53 and from the cylinder 31, to which the disk is connected, by overcoming said spring 56. W hen thus disengaged, the shaft 45 can be turned until one of its arms having a pin 51 is engaged under the head of a screw 57, as shown in Fig. 14. The cylinder 31 can then be readily detached for substituting a new record-sheet or for other purposes. The construction permits the cylinderto be initially adjusted to bring the record-sheet in suitable relation to the pen. To render the cylinder easy of application to or detachment from the clockcase, an open journal-bearing 58 is provided with flaring guides 59.

60 denotes rubber bands to hold the recordsheet on the cylinder. Metallic holders here- IIO tofore employed have proved inconvenient and unnecessarily expensive and those extending lengthwise the cylinder obstruct the pen. Rubber bands avoid these objections and are specially advantageous in application and operation.

61 denotes a milled disk for adjusting the cylinder.

62 is a socket to receive a key for the clock mechanism and is placed on the face of the clock-case next the cylinder.

63 denotes a glazed inspection-opening in the case.

64 is a short post to receive the sprocketband for transportation or when not in use. The band is coiled in a receiver 65, which is placed on the post.

66 denotes a screw fixed to the post and passing freely through the top of the receiver. The weight 36 has a screw-threaded socket to engage said screw and hold the band-receiver upon the base and also secure said weight thereto.

67 denotes a cover detachably hinged to the base, which is provided with a cover-seat 68 and with loops 69 in the seat to receive the hooks 70, fixed to the cover. Opposite this hinge connection is a hook 71, held in a keeper 72 by a spring-pin 73. The cover-seat is below and exterior to the upper surface of the base to exclude rain, wind, or dust.

74 denotes a pocket in the cover to receive the float, and 75 is a pivoted spring to hold the float in the pocket.

In practice the float having been suitably connected to one of the sprocket-wheels and counterbalanced will be suspended in a well or bay situated in the liquid whose height variations are to be recorded to protect it from the action of waves, tides, or winds.

The instrument having been suitably arranged and the clock wound to run, preferably for a week at least, the pen (or pencil) will be continuously moved along its supporting-rods and the paper transversely moved under the pen by the counterbalanced float, actuated by changesin the liquid-level, such changes being recorded on a suitably-grad uated sheet.

I am aware that an automatically-reversible pen-stock carrier has been operatively supported upon two parallel screws combined with a guide-bar, one of said screws being positively and the other mediately driven by an incased motor. In such construction the positively-driven screw had a bevel-gear or pinion situated on its end outside a screw-rod bearing and on its opposite end a gear-wheel also outside a screw-rod bearing, whereby the ready removal of the screwis prevented. In my construction the screw 3 has a readilydetachable bearing in the motor-case beyond its gear 3 and the guide-rod 9 has its proximate end detachably connected to the motorcase, the opposite ends being held in the bearings by a detachable bar.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1; In a recording water-gage comprising a cylinder actuated by a float, a plurality of power-transmitting wheels of different sizes and having different shafts and adapted to be operatively connected in alternation with the float, one of said wheels being adapted to be moved to a situation of rest when the other is in operation, and an adjustable stop for the movable wheel to hold it either in or out of operative connection.
