WILLIAM L. MORRIS, OF CHIGAGO, ILLINOIS.

HIGH-SPEED RECORDING-GAGE.

To all whom it may concern:

Be it known that I, WILLIAM L. MORRIS, a citizen of the United States, resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in High-Speed Recording-Gages, of Which'the following is a specification, the principle of the invention being herein .explained and the best mode in which I have contemplated applying that principle, so-as to distinguish it from other inventions.

My invention relates to recording gages, and particularly to such gages as are designed to have a plurality of cycles or turns whereby a high speed'of revolution or reciprocation can be obtained, and, consequently, a very detailed record of the varying pressures that are measured.

Said invention consists of means hereinafter fully described and specifically set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such dis' closed means constituting, however, but one of the various mechanical forms in which the principle of my invention may be ap plied.

In said annexed drawings :-Figure 1 represents a vertical longitudinal section of a form of mechanism embodying my invention; Fig. 2 represents a horizontal section taken upon the plane represented by the line 2-2, Fig. 1; Fig. 3 represents a diagram of a chart used with the mechanism illustrated in Figs. 1 and 2; Fig. 4 represents the chart as it would be when rolled into position and gummed upon the drum; Fig. 5 represents a side elevation of the rock-shaft that oper ates the marker; Fig. 6 represents the lower end of the drum-supporting screw and the stop-pin to prevent the drum from falling off Fig. 7 represents a vertical section taken upon the plane indicated by the line 7-7, Fig. 8, the parts being developed into a straight line to aid in showing the details; and Fig. 8 shows a plan of the clock mecha nism used to operate the revolving cylinder.

The object of my invention is to design a recording gage that can be operated at a greater speed than those which have been heretofore in use, and at the same time provide achart upon which the pressures can be recorded and which are readily adapted for filing away for reference.

- In my invention I obviate the difficulties Specification of Letters Patent.

heretofore connected with the use of chart supporting mechanisms of limited area by providing means whereby charts carried by said mechanisms are passed by the marking instrument a pluralit of times; also by providing means whereby the relative positions of said chart and said marking instrument are changed at each cycle so as to present a new portion of the chart to the marking instrumenteach time. The mechanism adapted to meet these requirements is not material, and may assume a great number of forms comprising a cylindrical supporting member adapted to revolve and simultaneously move axially, thereby bringing a new portion of the chart into the path of the marking instrument every revolution thus the drawings presented herewith, to which reference has been made, and in which the same reference letters refer to like parts, is shown my preferred form of apparatus for securing the plurality of cycles of movement of the supporting member for the recording chart, and the means for presenting different portions of said chart to the marking instrument at each cycle.

The chart supporting member is a cylindrical drum A, Figs. 1 and 2. This drum is carried by a screw B, which is supported by the cross-arm C and the posts C. The latter are received in the base or body D' by means of the tapped bosses D. Flanges D are provided for the body D, whereby it may be attached to'a wall by means ofbolts in the holes D This body D is in the form of a box with the front end open and provided with a hinged door D with glass D in the same. below the box at the back of the same, as in dicated in dotted lines in Fig. 2. Two large circular openings are provided in the case through which the drum may pass, and rims D are stiffening edges for these openings. A Bourdon spring for giving movement to the marker is shown at E with a nipple E for pipe connection of the same with-the pressure to be measured. Pivot screw E connects the spring to the marker mechanism. The marker pen is shown at F with an arm F to carry the same, the latter being connected to a bell-crank F which is carried on a pivoted shaft F. This latter shaft is supported on needle points in the supports F which screw into the body or case D. The screwF is provided by means of which the marker may be withdrawn the The flanges D are placed above and marking.

I nated at H which can be set at the elevarequired distance from the chart. A second screw F is provided for preventing the marker from bearing too heavily upon the chart. The latter thus serves virtually as a guiding screw. For the purpose of regulating the amount of marker travel to correspond with the chart lines, a clamp and screw F 7 are provided. Connection F communicates motion to the marker from the Bourdon spring E by means of the pivot F and the pivot block F Adjusting screws F enable the raising or lowering of the working range of the marker F.

G designates a revolving marker release adapted to hold the marker off the chart until the latter is in position or ready for the The marker release G is provided with a side bar G eccentric with G,

a handle G and stops G adapted to hold the release against or away from the marker arm F.

A second marker, whlch 1s fixed, 1s desigtion upon which it is desired to show the line on the chart. The pen or indicator is shown at H, which can be moved toward not been previously provided.

the chart by slacking the nut H and sliding the marker H in the slot H which lies on the radial line of the drum A. By means of this fixed pen H the accuracy of ,the chart can be checked, and also with it, standard lines can be drawn, in case they have The drum-supporting screw B. which is preferably a double-thread of about a of an inch pitch, has two nuts B and B Fig.

1, at its upper end provided with thread engagement. By means of these nuts the drum A and screw B ,can be raised or lowered to enable the setting of the marker pen H so that the latter will trace over a printed line. It is necessary to slack off the tap nut and revolve the drum if the marker pen does not stand over the correct time, when the chart is started.

J, Fig. 1 shows the support of the thread engaging mechanism provided with a shaft 7' and a conical rim roller or wheel J with a fixed holder on the shaft of J at the back of the bearing at J so that the tension of the spring is given to the washer and support J instead of forcing the wheel J against the screw B. The small pin J 3 prevents the shaft and wheel J from falling out of their places when the drum A is handled off the screw B. The driver sleeve is shown at K, Figs. 1, 7 and 8, and is provided with a feather K which engages in the feather-way B on the screw B, the feather-way having a lution of cylinder A about the sleeve, since the cylinder normally tends to move helically along the screw B under the force of gravity. Obviously by using a dlfferent form of thread-engaging mechanism than the wheels J and associated parts, as for instance an ordinary nut, the combination of sleeve and clock or equivalent motor would form a positive drive instead of merely a regulating device. Such clockworks connect with gear K and K which are carried on the sleeve K. Gear K engages with a train of gearing to the main spring K winding key K ratchet K and intermediate gears K. The gear K connects with the timing escapement through the train of gears K escapement K balancewheel K, and hair-spring K. The clock details are of standard construction, the main spring -being quit-e light, since the weight of th e drum tends to operate the clockworks. When the nut B is tight, the drum A can be revolved around the screw B only as the clock works permit the same. The cap A over the clock works, shown in Fig. 1, is dust-proof to protect the parts. Drum A is carried by the clock by means of the screws A Fig. 1, that screw into separate parts of. the same.

In connection with the lower end of the drum A there is provided a ring A Fig. 1, adapted to fit over and be frictionally secured to such end when the chart A has been rolled about. the drum and its edges gummed together in the manner above described. Such ring it will accordingly be seen will serve to support the chart, retaining it in whatever angular position upon the drum it may have been placed.

The chart A, Fig, 3, is rolled around the drum, as shown in Fig. 4, with the lines L and I) coinciding when laid upon the drum. To remove the chart, a knife is passed along the crease at L" leaving the narrow gummed strip remaining at the left side of the sheet along the line L. The holes L are provided for the purpose of filing. The lines L pass along the point of the indicator H, shown in Fig. 1, and can be either printed on the chart or plotted with the fixed pen H.

These lines are standard lines and represent a known pressure or amount. If the pres sure is to be changed, the screws F and F can be adjusted as is necessary, using a standard test gage. The smaller subdividing lines L give the amount of variation from the standard lines L it having been noted on the chart what this may be, and the amount of pressure variation from line L .to line L also noted on the regular pressure gage. The lines L are noted with the hours that each line starts on the left hand side designated by number L and by the numbers L on the other end of the line showing the time at which the marker pen F ran off the line. The lines L show the number of minutes past the hour at which the marker pen F passed along the lines L or L The marker pen F starts at line L on lower line L or L at either 12 oclock noon or night, and place for noting this starting period is provided on the chart, as shown. When the chart is completed at the end of the twenty-four hours, the marker pen will be at the upper line L or close vicinity and on the line L near the upper figure 12.

The chart, drum and clock works are removable from the case D and the screw B by giving the drum a slight turn with the hand, carrying the wheels J over the stoppin 13*, Fig. (5. The feather K disengages from the screw B ust previous to the time at which the wheel J comes into contact with the pin B thereby leaving K free to revolve out of engagement with screw B, and allowing the drum to be suspended on the screw B until the attendant takes the drum out and replaces the chart with a new one. In replacing the drum ready to startv the chart, it is lifted up to the end of the screw, revolved until the feather K meets its feather-way B and raised up to its full height, the wheelsJ recoiling back against their springs, as they are pressed back by each tooth of the screw B. The tension on these springs is quite light, asthe wheels would stay to tooth without the same.

The operation of my improved recording gage is as follows: A chart is moistened at the gummed edge, placed over the drum and secured to the same. The drum is then raised up to its place; the screw B is slacked ofi' and the drum, together with the screw, is-revolved around to its proper time, this being the same as the regular clock would show, hour and minute. After setting the time, note is taken to ascertain if the set lines L correspond with the indicator II, and, if it does not, the proper adjustment is secured by means of the two nuts B and B The nuts B and B are then locked. The retractor arm G is then turned around to allow the pen F tocome into contact with the chart, and the same is made to bear properly upon the chart. The marker is caused to rise above the standard, set line L by the Bourdon spring E or to fall below said line, according as the spring is straightened out more or less by a greater or less pressure than the pressure necessary to secure a standard line L The amount that the marker indicates above or below the standard lines L is a known quantity and stated on the chart. The chart and drum are caused to rotate, and, in order to expose new portions of the chart for each time the marker travels over the chart, the drum and chart drop on the screw an amount equal to the drop of lines L also equal to the vertical distance between two adjacent lines L The end of one of the lines L is, on the drum, the beginning of the next one, thus providing one continuous thread when exposed on the drum. When the chart has run its full amount, it ceases to revolve further, and the marker F- retraces its path as given by the spring tube E. Many variations of my invention may be provided without departing from the same, the spirit of which is to provide mechanism that shall pass the chart by the marker a plurality of times, and change the plane of travel each time, so as to successively expose new or untraveled portions of the chart.
