BRUCE D. WGOLLEY, OF JOHNSTOWN, OHIO.

- PERMANENT AUTOMOBILE Application filed December My invention relates to a permanent automobile service chart reminder. Automobiles as at present designed require, like all other en, in order to prevent undue wear upon the motor and to obtain the best operating results from the machine. Certain parts, of course, must be greased and oiled every five hundred miles orso. The battery mustbe checked fromtime to time to see that it has water, and to see that it is charging prop; erly. Then, the tires must be checked every so often to see that they have the proper air pressure. g

Ordinarily, it, is difiicult for a car owner or user to keep in mind the times at which these various service acts should be performed, with the result that machines are ften allowed to go for days or weeks be yond the time some one, or all of these service ac-ts should have been taken care of. This very often results in serious damage to that part of the machine so neglected.

One of the objects of my inventionis to provide a permanent record or reminder to the driver or user of an automobile, so that he may always have before him on the dash of his machine, a chart which will. definitely indicate when these various service acts should be performed, in order that his automobile may be kept in the best running condition, and thus avoid damage to the various parts requiring such attention. I'obtain this object by the device illustrated in the accompanying drawings, in which:

"cator means, with a portion of the face disc therebetween. I

The preferredembodiment of my invention comprises the discs 1, 2, 3, 1, and the washer 28, held together in their center by a rivet 13. The interior discs 2 and 3 are 'rotatably mounted upon said rivet 13. The face disc 1, and the back disc 4- are integral with eachother, being stamped from a single pieceof material, and held together by the narrow connecting strip 29, shown as broken away in Figure 2. Having the face disc 1, and back disc 4 joined together by 'means of the connecting strip 29, causes them to remain stationary while allowing the interior discs 2, and 3 to rotate upon therivet 13. w

The disc 4 serves as a back formy device, andhas stamped thereon two series of annularly disposed indentations 18 and 19 near its outer periphery, the purpose of which will be hereinafterexplained.

In front of the disc 4, and rotatably mounted upon the rivet '13, isjthe smaller disc ,3, having numerals from 1 to 56 or higher if desired, printed thereon near its outer periphery, representing mileage in thousand miles, and intended to register with and be seen through the opening 12, in the face disc 1. Forming a part of said disc-'3 is a small extension 17 acting as a handle or gripping means for turning the said disc 3.

Onth'e rear of the vertical portion of this extension 17, it has stamped thereon a small boss 27 (best shown in Figure 4), so that when my chart is in assembled positionand the discs held tightly together by the rivet- 13, thesaid boss 27 will be received in one of the small indentations 19 on the back disc 4, and thus prevent the disc 3 from accidental rotation or displacement with respect to the opening 12,0f the face disc 1, and yet allow the disc to be easily rotated. whenever desired. The user merely taking hold of the horizontal portion of the extension 17 and rotating the disc 3, the boss 27 merely riding out of one indentation into another in the annular path 19, until the number desired by the user appears in the opening 12 of the face disc 1. v I

In front of disc 3 is a disc 2 rotatably mounted upon the rivet 13. Disc 2 is of such smaller diameter than disc 3 as not to obscure-"the numerals on disc 3 from regisdisc 3, disc 2 also has numerals from 1 to +17, or higher if desired, printed near its the horizontal portion of the extension 17 to pass through said U-shaped projection 30 without interference.

On the rear of the vertical portion of the extension 16, above the U-shape projection 30, is a small. boss 26 (best shown in Figure 41;). When the chart is in assembled position and the discs held tightly together by the rivet 13, the said boss 26 will be receivcd in one of the small indentations 18 on the back disc 4, and thus prevent the disc 2 from accidental rotation or displacement with respect to the opening 11 of the face disc 1, but yet allowing the disc 2 to be rotated whenever the user wishes to change the mileage shown in the opening 11 of the face disc 1, the boss 26 merely riding inand out of the indentations 18 in their annular path on the back disc 41-. Between the disc 2, and the face disc 1 is a spacer washer 28 (best shown in Figure 4) preventing contact between disc 2, and the face disc 1 or between projecting parts of said discs.

The face disc 1 has openings 11 and 12. Through opening 11 may be seen any desired numeral appearing on the interior disc 2.

Adjacent the opening 11 and to the left thereof is printed the legend Grease car at,

with arrows pointing to the numerals ap pcaring in the opening 11, thus indicating the mileage at which the automobile should be greased, and oil. placed in various oil cups placed on various parts of the machine.

Through opening 12 may be seen any desired numeral appearing on the interior disc 3. Adjacent the opening 12 and to the right thereof is printed the legend Change oil at, with arrows pointin to the numerals appearing in the opening 12, thus indicating the mileage at which the crankcase oil should be changed. To the right of openings 11 and 12, respectively, on the face disc 1 are printed three ciphers, 000, so that when the numerals appearing in the respective openings 11 and 12 are rotated adjacent therewith, the mileages appearing in said openings will register in even thousand miles.

Underneath the said ciphers, on the face disc 1, adjacent the respective openings 11 and 12, are also printed three numerals to indicate 500, so that when the numerals appearing in said respective openings 11 and 12 are rotated adjacent therewith the mileage will be indicated in thousand, five hundred miles. This provides for a record to be made for ren'iinding the car owner or user to, change his crankcase oil and greasing his car every five hundred miles, which is usually as often'as these service acts need to be performed. The owner can thus start his car 011 by having these service acts performed at either of these mileages, the even thousand or the thousand, five hundred miles, and continue to have these service acts performedevery five hundred miles tl'iereafter.

I do not limit myself, however,-to merely recording mileages every five hundred miles, as provision may be made to record the mileages when these service acts should be performed every hundred miles without departing from the scope of my invention.

On the lower half of the disc 1, it will be noted that the disc has three semi-circular guideways 5, 6, 7 cut therein. Above the guideway 53 are printed the months of the year. Between guideways 6 and? there are numerals from 1 to 31, inclusive, representing the days of the month. I

Mounted in the respective guideways 5, 6, 7, and slidably movable therein are clip indicators 8, 9, and 10. These clip indicators are made in two parts, an upper part 22 and a lower part 23 (best shown in Figure clamped together by a rivet 2- 1, slidably movable in the said respective guideways, and so as to hold the upper part 22 and the lower part 23 in frictional engagement with the face disc 1 therebetween. The grip of these indicators 8, 9, 10 on the face' disc 1 is increased by making them of spring material, and by having small bosses 25 on the sides which contact with the face disc 1 and thus ensuring against their accidental displacement or movement in the respective guide ways. i

The clip indicator 8 is intended to be moved in its guideway 5 to indicate any particular month printed above said guideway 5 at which the tires or battery are to be checked. The particular date the tires are to be checked being indicated by movement of the indicator 9 along its guideway 6 until it points. to the particular date below the guideway on which it is desired to check the tires. The clip indicator 10 is similarly moved along its guideway 7 until it points at the particular date above the guideway upon which it is desired to check the battery.

My automobile service chart reminder may be fastened to the dash of an automobile by means of a bracket and thumb-screw or by any other well-known fastening means.

In Figure 3, I show a casing 31 with a glass face which is adapted to be used with my chart when desired. This casing is hinged to the connecting strip 29 of the chart by the hinge 32, and snapped at the bottom to the back disc 4 by the snap fas tening means 33.- This casing has the advantage of providing a casing for my chart, protecting it against dirt and giving additional protection against the accidental displacement of discs, or clip indicators, and in addition being easily opened whenever changes in the chart indicating means are desired to be made.

The operation of my device is as follows:

When the person wishes to make a record of the date at which thetires on his machine are to be checked for pressure, he slides the clip indicator 8 along the guideway 5 until it registers with the month in which the tires are to be checked and then moves the clip indicator 9 along its guideway 6 until it indicates the future date at which he desires to check his tire pressures. These indicators being in frictional engagement with the face plate 8 will remain in this position and serve as a permanent re-' minder to the party using the same. If the user of a chart Wishes to make a record of the date upon which his battery is to be checked to see if it contains water or 151 charging properly, he merely takes hold of the indicator 10, and moves it along its guideway 7 to the date in the future at which he intends to have it examined. As time and batteries are generally checked more than once in the month, the same month indicator may be used for tires and batteries. If, however, the months for some reason or other do not coincide the indicator of one or the other will be understood by the user to be of the preceding month, so that it is believed that only one month indicator is needed for both tires and batteries. I do not limit myself to one month indicator, however, as an additional month indicator may be provided, if desired.

It will therefore be apparent from the above description that by the use of the indicators 8, 9, and 10 upon the disc 1, a permanent record may be kept by the user of such chart so thathe will definitelyknow when he should service his tires and battery.

ii 'hen it is desired to make a record of the mileage at which a car owner or user wishes to change his crank-case oil he merely takes hold of arm 17, and revolves the disc 3 until it registers in the opening 12 of the face disc 1 the appropriate numeral to indicate the mileage at which he wishes to change his oil. The boss 27 on the arm 17 will register with one of the indentations in the row 19 and hold the disc 3 against further movement. Thus, in the opening 12 will appear the numerals indicating the mileage at which his oil should be changed so that when the mileage on his speedometer registers the figures shown in the opening 12 of the disc 1 he knows that it is time to change his crank-case oil. In the same .will of course manner the user of such a chart may make record of the mileage at which he wishes to grease various partsof his machine. This is done by merely taking hold of the arm 16 and moving the discs 2 until it registers 1n the opening 11 of face disc 1 the desired mileage at Which his car is to be serviced withgrease. The boss 26 onthe arm 16 thereupon register with its appropriate indentation in row 18 on the face of disc 4 and hold said disc 2 against moved by the user of the chart.

. From the above description it will be apparent that I have devised a simple and efficient service chart reminder for automobiles by which the owner can always have before him on record of the mileage at which he should change his crank-case oil, and a record of the mileage at which he should have his car greased, as well as a record of the dates on which he wishes to check his tire pressures and service hisbattery. .This device is so provided that all of the various service acts required by the owner of an automobile to keep his car in running condition are taken care of. The device is simple in operation and efli'cient in results. It is provided against accidental displacement of the discs and the tire and battery indicators are so provided that they will not move in their guideways unless by the purposeful act of the user of the chart.

It will also be noted thata great portion of the disc 1 is free of any indicia, which space may be used for directions for the servicing acts above referred to or for advertising purposes.

The device is so constructed that it may be made of inexpensive materials, designed to sell at a small cost, or given away as an advertising medium, or it may be made as permanent equipment for motor cars by using therewith as a cover the casinghere- 'inabove described and shown in Figure 3 of the drawings.

Having thus described my invention, what,

I claim is:

1. A service chart reminder comprising a face disc having openings therein and a back disc rigidly attached thereto, interior rotating discs mounted on av spindle, one of said rotating discs being adapted to register with an opening in said-face disc to indicate the mileage point at which the car is to be greased,another of said rotating discs being adapted to register with another opening in said face disc to indicate the mileage point at which the crankcase oil should be changed, a means for spacing the rotating discs from the said face disc, and means for maintaining said rotating discs in their adjusted po sition against accidental rotation or displacement.
