REGISTERING AEPAIEATUS FUR TAXIFEETERS AND THE LIKE.
Application filed s in 10,
'10 all whom it may concern:
Be it known that I, Bor ow Sonijnzarsnh, a citizen of the German Empire, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Registering Apparatus for Taximeters and the like, of which the following is a specification.
This invention relates to registering apparatus of the type in which lines are traced automatically by apencil on a record sheet. These lines serve to register certain movements or sequences of events and their dependence on other movements or events. As an example, an apparatus of this type designed for a taxinieter should indicate by means of the record lines what are the tariis at which the taximeter was working, what distances were traveled while the respective tar-ills were in operation, the times at which the taxirneter was put into operation and when the separate distances traveled were completed. The times at which the respective events are recorded, (the settings to different tariffs, and the respective distances traveled,) are indicated because the paper strip or disk on which the record is made, is moved forward uniformly and continuously,
so that each instant of time corresponds to a certain section of the record. The movements of the pencil corresponding to the different operations to be recorded are made at right angles to the direction of movement of the paper. If different events are to be recorded, (6. g. in the above example, the (lifierent tariff settings of the instrument and also the distances traveled, the movement of the pencil must be ellected hy various operating mechanisms. In addition to these possibilities of movement of the pencil which necessitate already quite complicated mechanism, two further movements of the pencil have to be provided for in the usual constructions. In the first place the pencil must be able to move vertically to and from the paper surface against which it must he pressedwith a light spring pressure, so that the line is drawn with a uniform pressure of the pencil and so that the pencil is fed up automatically as it wears away. Secondly, the pencil must be capable of being moved by hand completely to one side, for instance when the paper 'strip or disk is to be changed, and this has to he done daily with Specification of Letters Ea tent.

many types of registering apparatus. Further, if the pencil is not pushed to one side, the record cannot beread just at the place where the pencil is resting.
New this invention consists in mounting the pencil carrier on the cover which serves to close the casing and is hinged thereto, in such a way that when the cover is closed engagement takes place with the operating mechanism by which the pencil is moved corresponding to the events to be registered, and the pencil is raised oil' the paper surface and pressed to one side when the case is opened, so that neither the reading of the records nor the removal of the record paper are hindered in any way.
One form of construction of the invention is shown in Figures 1 to 5, and an alternative form is given in Figs. (3 to 11 of the accompanying drawings :Fig. 1 shows a registering apparatus for a taximeter with its door open; Fig. 2 is a cross section on the line A-B of Fig. 1 with the door open; while Fig. 3 is the same cross section with the door closed; Fig. t is a cross section on the line AC of Fig. 1; Fig. 5 is a side view of the pencil carrier; Fig. 6 shows another form of registering apparatus for a taximeter, with its door open; Fig. 7 is a cross section on the line A-B of Fig. 6 with the door open, While Fig. 8 is the same cross section with the door closed, showing the connection with the vehicle; Fig. 9 is a cross section on the line A-G of Fig. 6; Fig. 10 is a side view of the pencil carrier; and Fig. 11 shows the cam which serves for moving the pencil carrier.
In both forms of apparatus a is one wall of the taxiineter apparatus. to which the case b of the registering a paratus is fastoned.
7) is the cover of the case which is attached to the latter by means of the hinge c. and is held closed by means of the staple (Z and clasp (Z which can be made secure against opening by a lead seal or a pad look, so that the registering apparatus and the record card are only accessible to anthorized persons, 0. g. the cab proprietor. A shaft 6 driven by clockwork projects through the wall of the taxiineter apparatus and through the back of the case Z) into the latter. This shaft carries a pinion 7 which drives a toothed wheel 9 causing it to ro circular disk of the nave of the tee once in 24 hours. A paper it can be placed on toothed wheel 5 and h ld in place by the nut 2'. The pap disk is divided into 24 hour divisions a:- l nto a number of annular strips correspon with the number of tariff or the r he to be recorded. pencil is moved into position overone or other of the annular spaces by setting the taxiincter to one or other of the tariffs, when the pencil makes to and fro movements within the width of the strip over a length corresponding to the distance traveled.
In the 'form of construction shown in Figs. 1 to 5, the actuating of the pencil is not effected directly, but it is done with the help of an additional lever is attached to ashaft Z. The shaft Z passes throu l1 corresponding ope gs in the case b and the taximeter wall a, into the interior of the taximcter and is moved to the correct position by one orother of several independent mechanisms (not shown) corresponding with the arious tar-ill to one of which the instrument is set,- and it also caused to move to and fro continuously during the running oi the which at a rate which increases and decreases with, and corresponds to, the rate at which the vehicle is moving, so'as to cover a stretch corresponding with the distance tra wlcd. The to and fro movement of the slia l't Z is caused by a cam or other suitable mcchanima operated by the vehicle wheels. In Fig. the shaft Z is shown as connected to th nexible shaft 5 operated by the lever 2 which is vibrated by the cum 2 carried by'or concentric with the vehicle. wheel, a spring 3 holding the lever in con tact with the cam. The pencil carrier onis mounted to turn on the cover 6 ofthe case. A sprin 72 tends to press'the pencil carrier agaii' the end of a pin 0. The pencil 2) slidably mounted in the carrier on and is pressed by a spring 9 against the paper sheet it when the cover is closed. The projection 1* serves a support or table for the paper disk where the pencil works over it Vi'hen the lid o isshut (see Fig. 3), the pin m attached to the pencil carrier. m presses against a nose k on the lever is. The pencil carrier m is thus caused to be pressed aside against the action of the spring a, and the pencil p is automatically, brought over the correct part of the record disk. The pencil now follows the movements of the lever 11'. When the lid is closed the pencil y; makes circular movements (which correspond to thedivisions for the intervals oi time on the paperdisk) independently of whether the movements of the lever corresponding'to the various per-' formances to be recorded are partly straight line movements and partly turning movements about another aizis. The time of recording or each point on the record lines ment through a comparatively traced out can thus be ascertained accurately and Without risk of error, by its position in its annular strip.
When the case is open the face of the paper disk It is entirely exposed. Hence the lines drawn are completely visible to their ends, and the record disk can be easily changed. V g p The form of apparatus shown in Figs. '6 to 11 differs from that described above in that not only the pencil carrier, butalso a part of the mechanism which directly op' crates the pencil carrier is carried by the cover, and that when the cover of the casing is closed, these parts are brought into engagement by suitable means with the parts which actuate them anld which are located in the casing. This arrangement has the advantage that the adjustment of the movements of the pencil can be carried out more easily.
The pencil carrier m is pivotally mounted on the lid 6 of the case. A spring 91. tends to turn the pencil carrier m until its arm m comes against a cam '0, The cam o is fixed one shaft to revolubly mounted on the lid of the case, on the other end of which shaft :1 bevel wheel 2, is fixed. This bevel wheel engages-,when the lid is closed, with another bevel wheel 8 arranged in the casing, and whose turning movements correspond with the records to be made. The pencil p is slidably mounted in the pencil carrier m and is pressed toward the paper by a spring 9 when the cover is closed. A projection 7 serves as a support or table for v the paper disk b. When the cover 6 is closed (see Fig. 8) the bevel wheel t comes into engagement with the bevel Wheel 8. The pencil carrier with the pencil p is now moved to and fro by the cam 12 in a manner corresponding to the movements of the'bevel wheel 8.
In the form of apparatus illustrated it is assumed that when the tariff of the .taximeter is changed from one rate to another, the bevel wheel 3 is turnedby a single movelar'ge angle, after which it is moved periodically to and fro through a smaller angle at a rate which corresponds to, and increases and decreases with, the rate atwhich theehicle is moving so as to make a record corresponding with the distancecovered Consequently a line will be traced by the pencilp on the paper disk it as indicated in Fig. 6, and this line serves to show at what times the taximeteri was moved into its diherent tariff positions, and also what distances were covered at the various settings and at the respective times. Thus on the disk shown in Fig. 6,1-the different concentric rings represent the'difierent tariffs and the change in tarifi' iis indi- 1 cated by the change imposition of the line from one to another of these ringsthe time of change being thus indicated on the disk as Well as the tariff to and from which the change is made. Also on this disk the dis tance traveled is indicated by the number of transverse to and fro vibrations in the line within the particular ring corresponding to the particular tariff at which the vehicle is being operated. As the rate of movement of the vehicle increases or decreases, the num ber of these to and fro vibrations also increases and decreases, and to a corresponding extent, so that these vibrations indicate accurately the distance traveled, their frequency thus corresponding with the rate of movement of the vehicle. It will thus be seen that the rotary movement of the paper disk is continuous, and that the line on the disk will indicate the particular time at which any change of tariff is made as well as the period of time at which the vehicle is maintained at each tariff. It will also be seen that when the vehicle is at rest, the line will be a smooth circular arc, and that when the vehicle is in motion the'line will consist of a series of to and fro vibrations, whose number will correspond to the distance traveled within the time interval indicated.
lVhen the case is open the paper disk is entirely exposed. The line traced is there fore completely visible to its end, and the record disk can be easily changed, as in the first described construction. I claim herein as my invention:
