RECORDING DEVICE.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application med May s, 1909. serial No. 494,751.

To all 'whom t may concer-nt Be it known that I, EDWARD S. Conn, a citizen of the United States, residing at New York, in the county of New York and State of Newl York, have invented a cer-- tain new and useful Improvement. in Recording Devices, of which the Vfollowing is a full', clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this speciication.

My invention relates to hydraulic record-- ers,-th at is to say, to devices for recording the velocity and static pressure of flowing streams. y

The objects of the invention are to provide a simple, practical and inexpensive device of the class specified, to obtain accuracy of record, simplicity of operation, elliciency, durability, adaptability, and other desirable results as .will be hereinafter more particularly set forth. f

In the aceon'ipanyingdrawing Figure 1 represents a recording ldevice embodying my invention, said device being shown partly in verticaly section and partly n diagram; Fig. 2 is a view of said recording device partially in pla-n and partially in horizontal section, with a part of the structure broken away for convenience ot' illustration.

Referring to the drawing, I have shown a pipe 1, Which may be a water lnaiu or any other pipe or conduit carrying liquid whose velocity it isdes'ired to measure. This'` pipe, or conduit, 1, is provided with litot tubes:

'2 and 3, the former facing down stream and the latter up stream. These tubes a'and 3 are extended to a metallic casing Llcontaining a flex1bl`e diaphragm lcarrynig a metal -disk 6. Y The tubes 2 and 3 conu'ininicale with the interior of the casing '-i on oppositesides ofthe diaphragm 5, the tube 2 being below thediaphragni and the tube above it.' Levers 7, pivoted al S upon arms 9 carried: -by-ith'e casing 4, are arranged lengthwise?aboveffthe diaphragm 5, and

`connectedlwitlijthe metal disk l, and there 't theinner ends of the lever A i .tor 1l, 1 1,exlend up lo the free endiftls'ia ring 12, supported by' a block 155i on th'e side of a 'case ll, mounted upon and coinjiected with the upper chamber of the casing-4;# "'he llexible ronnoctors 1l 19 upon which is mounted a metal wheet 20. The wheel 2O travels upon a hard rubber board .or block 21, forming a segmental track 21, having a series of contacts 22. This track 21 is at an opening formed in the casing 14, so that while all the parts heretofore referred to are inside of the casings 4 and 14, the track 21 is outside of the same, except its inner tace or surface, upon which are arranged the cont-acts 22. 22. the contacts QQ, 2Q, to magnets 24, arranged alongside a recording cylinder 25, andarnis 2G are extended from the magnets Z4 to the cylinder or drum 25, and provided with recording pencils or pens capable of forming a record upon a record sheet onthe cyr-'linder 25. The latter `is driven by clock-wor; 2Q.

ln operation, the velocity of the tlowing stream causes the .pressure transmitted through the tube 3 to act upon the diaphragm 5, thereby depressing the samennd .causing the lever mechanism to dra-W down upon the spring' 12 and turn `the wheel or pulley 15. This in turn causes the gear 16 to bring about a turning actionof the pulley 13`l which in turn swings the arm 19, and causes the wheel Q0 to travel 'over the contacts 22. W'hen this is donc, circuits are closed` the magnets 'Q4 thereby causing the recording devices Q7 to act upon the record sheet on the drum 2.3 to form a record.

The device herein shown is exemplary of a type of device which can be much modified and varied` and I am showing it in the precise form here illustrated merely to illuslrate'its general principles of construction 'and operation.

The general features of construction and operation of the device. permit accuracy, sensitiveness and reliability to he obtained. There is no friction with consequent climination of errors from that source; land no trouble from -zfii ages of temperature, photogfraplrv, etc.

The use of a parabolic gear-or like eleiurnl. in the train of niechanisnn corrects the reading so as to compensate for decreased move-men* Conductors 23, 23 are extended fromy of the diaphragm prol rata as the 'velocity pressure increases. This same result can, if desired, be obtained by spacing the pencil magnets at decreasing distances, as shown and claimed in my Pat` ent No. 880,720, in which case the parabolic element. will be omitted.

As a matter of further improvement, I desirably arrange to have the casings t and 14 filled with water under pressure from the main.

It will be understood that changes and modifications may be made without departc ing from the. spirit of the invention.
