Patented Dec. 1, 1931 PATENT OFFICE ALEXANDER INGIiET ON ROE, ORANGE, NEW JERSEY AUTOMATIC SPEEDOMETER CHART Application filed June 16,
'15 pointed out in the appended claims.
I11 describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a fragmentary view of an instrument board of a motor vehicle showing the invention applied thereto.
Fig. 2 is a fragmentary view of the chart or map carrying strip.
Fig. 3 is a view looking toward the closed end of the drum.
Fig. 4 is a transverse sectional View through that part of Fig. 1 which carries the invention.
Fig. 5 is a View of the gear wheel.
Fig. 6 is a fragmentary view of part of the dog carrying lever.
Fig- 7 is a section on line 77 of Fig. 4.
Fig. 8 is a section on line 88 of Fig. 4.
Fig. 9 is a view of the dog. Fig. 10 is a side view of the drum. In these drawings, the numeral 1 indicates a casing which may be attached to the instrument board A of a motor vehicle or the like, this board having an opening 2 therein with a door 3 closing the opening and having a window 4 therein. A marker 5 is carried by the door and projects into the window as 5 shown in Fig. 1.
A large gear 6 has a stub shaft 7 connected to the center of one face thereof and this shaft extends into a bearing boss 9 formed in one of the side walls of the casing. A fric- 56 tion disk 10 closes the outer end of the boss '1931. Serial No. 544,840.
and carries a set screw 11 which is threaded into the hub or stub shaft- 7, these parts acting to frictionally hold the gears against rotary movement. The gear is provided with the ratchet teeth 12 which are engaged by a dog 13 pivoted to a lever 14 which is pivotally supported intermediate its ends by a bracket 15 in the casing. This lever has its dog carrying'end bent at right angles as shown in Fig. 6, so as to properly position the dog to engage the gear.
A spring 16 is connected with the lever and a part of the base and normally holds the dog in lowered position. A leaf spring 17 pushes the dog into engagement with the teeth of the gear. That end of the lever 14 opposite the end which carries the dog is engaged by a cam 18 on a. shaft 19 which is geared to a part of the mechanism of the speedometer B and the parts are so arranged that the ratchet wheel 6 will make a step by step movement under the action of the dog and I prefer to space the teeth onetenth inch so that the ratchet will be moved one-tenth inch for each revolution of the 7 cam which is operated by a gear of the speedometer, which makes one revolution per mile.
A strap 20 has one end fastened to the ratchet wheel 6 as shown at 21 with the major portion of the strap spaced from the wheel and a cylindrical-shaped drum having one end open and has loops 22 on its closed end through which the strap passes so that the drum, as shown at 23, can be detachably connected with the wheel 6 by placing the 35 loops of the drum over the strap as clearly shown in Fig. 4.
The strip carrying the road map is shown at 24 and this strip is placed around the outer circumference of the drum and has its ends passed through a slot 25 in the drum as shown at 26 in Fig. 4, to detachably connect the strip to the drum. The drum is so located with respect to the window 4, that the strip can be seen through the window and the marker 5 cooperates with the road map on the strip to indicate to the operator, just what position on the road he occupies.
The door '3 provides a means for removing the drum so that the strip can be removed therefrom and a new one placed thereon, after which the drum is again put in place and connected With the Wheel 6. 7
When the teeth on the ratchet Wheel are spaced one-tenth of an inch, the map or road strip is marked in one-tenth inches in spaces,
each spaceequalling one mile, Every ten miles may be enumerated and as s'hovvn the route is represented on the drum or strip as a straight line. It maybe provided With arrows pointing in the direetion to be taken-f in cross roads or forked roads. The routes may be named or numbered as the caseinay be. Cities may be marked by a curved line at their boundary lines With notation marks corresponding to abooklet showing streets to be taken until the boundary line is passed Where the chart or strip is again s'etto the propel position by using some line mark -whenthe strip Will be readyto guide the operator on the next lap-of his journey.- I
Thus the operator can readily follow th read by simply watching the strip and this device will 'beof great aid'in night driving as thereis no necessity to stop to look-at 7 signs or inquire for directions, as everything Having thus described for'the proper following of-a route is located on themap. L
It is thought from 'the foregoing description that the advantages and novel features vof the'invention Will-be readily apparent Y It to be understood that changes may be made in the construction and'in-thegeomparts, providedthat such changes fall within the-scope of the appended claims. 11
I claim asn'ew is i 1; 'A device of the class described comprising a casingjattachedto a part of a vehicle,
rocking the same, and means for operating the earn from a part of the speedometer.
' 3. In combination with a motor vehicle including an instrument board and a speedometer, an opening in said board, a door closing the opening, a Window in the door, a markercarried by the door andprojecting into the Window, a casing connected to the under face of the instrument board and en closing the Window, a ratchet Wheel rotatably arranged :ia-theeasing, friction means forresisting rotary movement of the Wheel, a lever pivoted-in the casing, a dog carried thereby engagingthe teeth of the Wheel, a cam engagingthe lever for rocking the same,
means for operating the cam from a partof the speedometer, a drum detachably connected With thewheeland adapted to be-passed through the openings, when the ijdoor is opened, anda route strip carried by the: .dr'um.
