CHRISTOPHER H. WATSON, OF RIVERSIDE, CALIFORNIA.

WATER-RECORDER.

Specification of Letters Patent.

Patented June 27, 1911.

Application filed November 7', 1910.- Serial No. 591,191.

To all whom 'it may concern:

Be it known that I, CHRISTOPHER H. WAT- soN, a citizen of the United States, residing at- Riverside, in the county of Riverside and State of California, have invented a new and useful later-Recorder, of which the following is a specification.

This invention relates to means for recording the height of water in weirs, ditches, reservoirs, etc., and one of the objects of the invention is to provide simple and efficient means for this purpose in which provision is made for successive use of different parts of the record sheet.

The accompanying drawings illustrate the invention, and referring thereto: Figure 1 is a front elevation of the device with the front closure door opened and` the parts broken away. Fig. 2 is a plan of the device with the top door or lid open and partly in section. Fig. 3 is a vertical section on line ac3- m3 in Fig. 2. Fig. 4 is a plan of the pencil-holding means with the supporting bars therefor shown in section. Fig. 5 is a vertical section on line c5- 005 in Fig. 4. F ig. 6 is a horizontal section of a portion of the holding drum for the record sheet, showing the manner of attaching the record sheet thereto. F ig. 7 is an elevation of the lower part of the drum.

1 designates a case provided with a door 2 at the front and with a cover 3 hinged to the top of the case. A bracket 4 extends forwardly from the rear wall of the case 1 and is formed with a cup or socket 5 constituting the lower or step bearing for a drum or cylinder 6 which holds the record sheet 7 Said drum 6 has a pin S extending downwardly at its lower' end to engage in the cup or step bearing 5 and said cylinder has a pin 9 extending from its upper end and engaging in a hole in an arm 10 extending forwardly from the rear wall of the case. Sufficient distance is provided between the top of the drum 6 and the arm 10 to enable the cylinder to be lifted far enough to remove the lower pin 8 from the bearing 5.

The drum cylinderv 6 is formed of sheet metal bent in cylindrical shape, with heads 12 and 13, said cylinder having a longitudinal slot at one side, one end of the metal sheet being bent in at this slotand extending beneath the other end so as to form a channel 14 extending longitudinally of the drum. The record sheet 7 coiisisting, for example, of cross-section paper, is bent along one edge as indicated at 15 and this bent portion is pushed into said channel, the body of the sheet being then drawn around the drum 6 and the said end being pushed into said channel 15 underneath the said bent end of the sheet, thereby securing the sheet to the drum or cylinder 6.

The means for making the record consists of a pencil or`scribe 17 secured in a clip 18 on an arm 19 carried by a vertical shaft 20, mounted in a carrier 21 which slides vertically on two guide rods 22 carried by brackets 23 attached to the back of the case. A spring 24 is secured at one end to said carl rier and at the other end to the said shaft, so as to tend to hold the pencil yieldingly toward the surface of the drum 6. The top of the carrier 21 is provided with a knob or projection 26 over which the arm 19 may be pushed to position shown in dotted lines in Fig. 4, thereby holding the pencil away from the drum, the spring 24 serving to produce a downward pressure on the shaft- 20 and the arm carried thereby as well as a rotative effect. The carrier 21 is connected to a float 30 by a rod 31, the upper end of this rod having a collar 32 in which is slidably mounted a vertical rod 33 connected to the said carrier, said vertical rod 33 having at its lower end a collar 34 sliding on the vertical rod 31 connected to the float, a set screw 36 being provided in the collar 34 to adjustably secure the said collar on the rod 31 and thereby hold the pencil carrier in fixed position relatively to the float.

The upper head 12 of the drum or cylinder 6 is formed with a groove 36 in which runs a cord 37, passing over pulley 40, and carrying a weight-41 at one end and passing at its other end around a pulley 42 on the case and a pulley 43 on the hour shaft 44 of a clock indicated at 45, and passing from said pulley 43 over a pulley 48 to a weight 49. The last named weight 49 is heavier than the iirst named weight 41 so that there is a continual tendency to draw the cord or belt in one direction and thereby rotate the drum by the action of the weights, the rate of the movement being regulated by the movement of the clock. A hook 50 is provided in the case 1 to receive the cord 37, for temporarily holding it out of Contact with the drum.

The device is used as follows: The case 1 is placed over the body of water or apparatus in which the level is to be recorded,

and the float bar 3l is adjusted with relation to the carrier 2l so that when the water is at a certain standard level, for example, just at the crest of the weir, the pencil 17 is at the proper height to mark on one of the horizontal lines of the record sheet, for example, the lowest line thereof. The clock being set in operation, the drum G is rotated continuously by the preponderance of the heavier weight 49, so that no dragging is exerted on the clock. rThe lighter weight Lll serves to maintain tension on the cord 37, producing sufficient friction on the grooved head 12 of the cylinder to cause the cylinder to rotate. The pencil l? being moved into position in contact with the record sheet as indicated in full lines in Fig. il, it will in the rotation of the cylinder, describe a line or curve on the paper, the height of this curve above the base line indieating the elevation of the water above the standard level. lt is preferred to so proportion the speed of revolution to the dimensions of the cross-section lines on the paper that each space on the paper represents one hour, and the complete revolution may conveniently represent one week. Viflhen one revolution has been made, the carrier supporting rod 33 is raised on the float rod 31 a sufficient distance to bring it in alinement with another horizontal line on the crosssection paper and fastened at such position, a second record being then obtained at a higher level, this operation being repeated so that the same record sheet may be used for a large number of successive weekly records, and when the sheet has been filled up in this manner it may be easily removed by opening the doors 2 and 8, pulling the cord 37 from the grooved head l2 of the cylinder 'g and hooking said cord over the hook on the case. The cylinder may then be lifted up so as to remove its lower pin S from the :iv bearing 5 and on then drawingthe lower end of the cylinder outwardly until it clears the bracket il, whereupon the cylinder may be lowered so as to remove its upper pin 9 from the bearing in the arm l0. The record sheet may then be readily removed from the cylinder by slipping out the lower inserted end and then the hook end of the record sheet from the channel l/l in the cylinder.

lVhat I claim is:

l. A water recorder, comprisii'ig a drum mounted to rotate on a vertical axis, vertically extending guide means adjacent to said drum, a carrier mounted to slide vertically on said guide means, a pencil mounted on said carrier, a float, a rod extending vertically from said float and a second rod connected to said carrier and slidably connected to said rod on the float and provided with clamping means for adj ustably securing it thereto.

2. In a water recorder, the combination with the record drum of a guide extending vertically adjacent thereto, a carrier mounted to slide vertically on said guide, a shaft journaled in said carrier and provided with an arm, said arm having pencil holding means, a spring connected to said shaft and to said carrier to hold the pencil toward the record drum and also to force the arm downwardly, said carrier having a projection over which the arm may be moved to cause the pencil to move to or from the contact with said drum, said projection serving to hold the arm in either position.

ln testimony whereof, l have hereunto set my hand at Riverside, California thisl 31st day of October 1910.
