I Patented Sept. 24, 1946 2,408,302 UNITED STATES PATENT OFFICE 2,408,302; RECORDING DEVICE. FOR AUTOMOBILES‘ Erik E. Eriksson, Base Line, Mich. ApplicationAugust 1, 1945‘, Serial: No. 608,123 3 Claims. (01. 40-68) 2 1 This invention relates to a recording, device, and" more particularly to a recording device of bottom of recess I3 for a purpose later to be de scribed, Directly opposed to recess I3 is an addi the type for use with an automobile where the tional shallow recess 25 adapted to receive a ownerv is desirous of determining the number of. ratchet bar 26 containing ?ve projections 21, the miles traveled between oiling and greasing" pee. use for which will appear more clearly in this de riods. finv object of‘ the present invention is to pro vide a new and improved device which in turn scription. that difference between the readings at any given moment will show the miles traveled since’ setting the recording device, and when this dif the wheel I ‘I per se. The ?ve wheels I l are at all times held against rotation by means of a ratchet bar 26 which seats within slot 25, said ference is shown to be,‘ in this instance, one bar having formed therein ?ve projections 21 which are in longitudinal alignment and adapted to engage aligned notches l9 formed in central opening of wheels I ‘I and prevent the wheels from rotating freely on shaft I2. A housing 20 is provided to enclose the working parts of the recording device, the same being se cured to the recording mechanism by means of Rotatably mounted upon shaft I2 are five wheels I ‘I, each wheel having a portion of its provides a separate recording of‘ an odometer outer periphery knurled I8, so that it may be and maintaining such a record reading for sub-v 10 easily rotated. The wheels are constructed suf sequent comparison with the total mileage read ?ciently wide to receive indicia, each wheel con tainin ten numerals peripherally arranged ing of the odometer. It is the custom. today to have thereon. Each wheel has a central opening an automobile greased and the oil’ changed after therethrough of sufficient diameter to allow the each one thousand miles of travel. The recorder is set to correspond with whatever the total mile-., 15 wheel to slide upon shaft I2 and each central opening has formed on the periphery thereof ten age reading. of the odometer may be at the‘ time; notches I9 each notch being radially aligned with Thereafter, as the odometer registers additional‘ a numeral appearing on the outer periphery of mileage, a comparison may always be had, so thousand miles, the owner knows that it is again’ time to change the oil and have the car greased;v A still further object of the invention is to so place the recording device so that it‘ is at all times; adjacent the ‘odometer and to provide a locking means for said, recording device to lock the same in a set position to prevent change of the setting. The above and other objects will appear more fully from the following more detailed descrip tion, and from the drawing wherein: Fig. 1 is a perspective view of the recording device as it appears on the instrument panel of an automobile. Fig. 2 is a front elevational view of the device as the same appears to the driver of a car show a set screw 2| which passes through an- open ing provided therefor in said housing into one end of shaft I2. There is also an opening in the front portion of housing 20 to allow plunger I5 to project therethrough. The entire working or leading edge of locking bar I4 is wedge-shaped 22, as shown best in Fig. 3 of the drawing, so that same may engage notches I9 when the device is in a locked position. The method of using the device is as follows: Fig. 3 is a vertical section of the device taken 40 In its normal position the device remains in substantially on the line 3-3 of Fig. 2; and what might be termed its locked position where Fig. 4 is a section taken substantially on the it has remained since the previous setting by the line 4—4 of Fig. 3. car owner.

As leaf spring I6 is flattened by said pressure, locking bar 14 passes into lon slot or recess I3, sufficient in depth to receive a 50 gitudinal recess I3 and becomes disengaged from locking bar member I4, said member being sub notches I9 and while looking bar I4 is in this stantially T-shaped, the stem of the T I5, act position ‘wheels I ‘I may be rotated on shaft I2. is suitably and non-rotatably mounted in bracket I0, the same containing a recessed longitudinal ing as a plunger for the purpose of bringing pressure to bear upon a leaf spring I6 which is Wheels I‘! cannot be spun on shaft l2 because they are at all times held against free movement interposed between locking member I4 and the 55 by means of ratchet bar 26 with ?ve engaging 2,408,302 4 projections 21 which projections at all times en gage notches H! which are in longitudinal align comprising, in combination, a housing having therein a bracket, a slotted shaft non-rotatably mounted in said bracket, a plurality of wheels ro tatably mounted on said shaft having central openings therein, indicia on the outer periphery of said wheels and a plurality of notches on the ment therewith, said engagement being through the notches opposed to those used to lock the device, the same being best illustrated in Fig. 3 of the drawing. The operator, to set the re corder, simply rotates each wheel by means of the knurled portion !8 thereon, contacting same through the lower opening in housing v2U.
