Serial No. 498,766.

To all 'whom it may concern.'

Be it known that 1, EDWIN SCHUETTE, of Manitowoc, Wisconsin, have invented a Chart for Recording-Compasses, of which the following is a specification.

This invention is a chart or schedule for making continuous records of the steering direction of a ship, such as may be made by the automatic action of the recording-pen or pencil of a registering-apparatus.

The object of the present invention is to provide a scheme for placing in a single (line all of the compass-rhumbs without breaking the continuity of the arrangement in passing from one compass-point to the next; so

"that they can be recorded by the continuous movement of the recording-point, and without breaking continuity as would be occasioned were it necessary for the recordingpoint to skip from one edge of the chart to the opposite edge, as has been the case in Some schemes heretofore devised.

The principle of my invention lies in the arrangement of separate rhumbs or compass directions on opposite sides of aegiven diametral ling-ordinarily the lubber-line ornorth-south diameter, in such a manner that symmetrical points with respect to said line are placed adjacent and in alternate relation in proceeding from one pole of said 'line to the opposite one. y

This application is a division of the United States application No. 441,892, filed June 22, 1908, for a recording compass, jointly by myself and Nicholas Dedrick.,`

1n the drawings hereto annexed, Figure 1 shows a scheine for a recording-chart in which only the full points, or ordinary 32 rhumbs, are used, and provided with curved lines for the swinging recording-point illustrated by our aforesaid patent, showing a portion of a sailing-record thereon; and Fig. 2 shows a fragmentary portion of a chart in i which quarterrhumbs are used, and designed for a recording-instrument whose recording-point moves in a straight line.

lIn these drawings the same part is designated by the saine reference-letter iny each gure. y

It will' be understood that this kind of chart comprises la roll of indefinite length 'on which the compass-record is inscribed,

- Vand in which the longitudinal element of di- Irection represents time and the transverse element the direction in which the vessel is headed. 4

As will be seen from the drawing, the north and south rhumbs are placed at opposite edges of the chart, and the rhumbs which are on either side thereof in the compass are arranged in alternate directions proceeding in regular order from one to the other; so

that north, for example, is followed by north-by-east, north-by-west, north-northeast,\northnorthwest, etc., successively; or where the directions are divided more minutely, as in Fig. 2, the direction north is followed successively by north-quarter-east,

north-quarter-west, north-half-east,` norththree-quarter-west, north-by-east, north-by- For the sakeV of distinguishing half-west, north-three-quarter-east, northwest, etc. the east and west directions readily by the eye andl projecting the eye longitudinally along the chart without confusion of lines, it is convenient to distinguish alternate strips of Athe chart by shading, hatching, or

coloration, as indicated by the `parallel'hnes shown.

Longitudinally the chart is divided either by curved lines a as in. Fig. 1, or by straight lines b as in F ig. 2; these lines representing equal divisonsof time; and in accordance with the usual practice the lines representin the greater divisions ymay be made heavier than others. Thus in Fig. '1 the aeV smaller divisions represent hours and the.

greaterV divisions periods of six or twelve Ahours each; while in F ig. 2 the smaller divisions are of `five minutes each andv the greater divisions thirty minutes and one hour respectively, while the date is written at one edge of the chart. Naturally I do not limit myself to any particular number of divisions or spacing betweerothe divisions, as this will be regulated ac rding to the ininuteness desired in the record.

In using the chart, the registering-apparatus is so constructed as to cause the record-l ing-point to pass Over always an even number of strips, so that it cannot pass from a white strip to a colored or shaded one without passing through one of theJ poles; leX- cept that it can pass from north or south to either a shaded or plain strip, but afterit has passed the second strip from either of the eXtreme strips it must stop always on either the plain cr shaded strips. For example the recording-point can pass for instance from north-by-east to north or from south-by-wesi to south. This is illustrated by the specimen record o shown on F ig. l of the drawings.

From the above description it Will be" readily seen that myinvention will assume a variety of forms, all embodying the same principles, and that a great number of changes and modifications are possible iir the iionessentials without departing from the spirit of my invention, the scope of which is particularly defined in my claims.

I-Iaving thus described my invention,what I claim as new and desire to secure by Letters Patent is:

l. A chart for a recording-compass divided into a plurality of longitudinal strips corresponding to the compass-rhumbs and arranged with two opposite rhumbs on o posite sides thereof and the rhumbs to rigiit and left of the rhumb-line-joining said opposite rhumbs arranged alternately in serial order proceeding from one of said extreme rhumbs to the other eXtreme rhumb.

2. A chart for a recording-compass divided into a plurality of longitudinal strips corresponding to the compass-rhumbs arranged with the north and south rhumbson opposite sides thereof and the intermediate rhumbs to right and left of the meridian arranged in alternate succession from north to south, symmetrical east and West rhumbs being adjacent to each other.

3. A chart for a recording-compass divided into a plurality of longitudinal strips corresponding to the compass-rhumbs and arranged with two opposite rhumbs on o posite sides thereof and the rhumbs to 'riglit and left of the rhumb-line joining said opposite rhumbs arranged alternately in-serial order proceeding from one of said extreme rhumbs to the other extreme rhumb, alternate strips being distinguished to the eye from the others as by coloring, shading or K the like.

t. A chart for a recording-compass divided into a plurality of longitudinal strips "fresponding to the compass-rhumbs arranged witli the north and south rhumbs on opposite sides thereof and the intermediate rhumbs to right and left of the meridian arranged in alternate succession from north to south, symmetrical east and West rhumbs being adjacent to each other, the east bearings being distinguished to the eye fi'om the west bearings, as by coloring, shading or the like.

5. A chart for a recording-compass divided into a plurality of longitudinal strips corresponding to the compass-rhumbs and arranged with two opposite rhumbs on opposite sides thereof and the rhumbs to rig t and left of the rhumb-line joining said opposite rhumbs arranged laterally in serial order proceeding from one of said extreme rhumbs to the other extreme rhuinb, and a plurality of transverse lines corresponding to equal intervals of time.

6. A chart for a recording-compass divided into a plurality of longitudinal strips corresponding to the compass-rhumbs arranged with the north and south rhumbs on the opposite sides thereof and the intermediate rhumbs to right and left of themeridian arranged in alternate succession from north to south, symmetrical east and West rhumbs being adjacent to each other; and a plurality of transverse lines corresponding to equal intervals of time.

In witness whereof I have hereunto yset my hand this 22 day of March, 1909.
