RECORDING APPAIA'I'UI.

Application flledleptember 8, 181. Serial Io. 497,807.

To all whom it may concern:

Be it known that I, FRIEDRICH WILHELM GUSTAV BRUHN, residing" at Berlin-Wilmersdorf, Nassauischestr. 64, Germany, have invented certain new and useful Improvements in Recording Ap aratus, of which the following is a speci cation. 9

My invention has for its object primarily recording apparatus designed to be employed for the supervision of the running times, speeds and nature of operation existing for the time being of vehiclcs 'of any description, also of railway vehicles, operativemachines, and other devices, which are tobe kept under suitable control and observation. To this effect, a counting mechanism indicating the total number of revolutions, or kilometers, or otherdistance units is driven by one part of the machine to be observed, c. g. by a wheel, whereas on the other hand a marking mechanism or scriber is set in motion which, on a dial or similar chart moved by a clockwork produces marks which permit of drawing conclusions reg-:rding the nature of operation of the mac ine or vehicle.

My invention refers more particularly to a novel arran ement of such recording apparatus intendedin the first'place to permit of an easily recognizable observation of the effectiveness of the marking device and of the operation to be supervised. Moreover rangement ofthe means for making the ob servations. It also comprises further the particularly advantageous design of the other parts of the apparatus in such manner as to permit of an exceedingly appropriate and simple arrangement of the various parts of the controllir device. Finally, myinvention contemplates the special design of the general arrangement wlth a view to an easy readability of the markings and of the counting mechanism, as'also the reliability and simplicity of operation, and the particular conditions under which the machine ma be 0 crating at the time.

v description.

ith t ese and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, forming part of this and ar- I The apparatus shown on the accompanymg drawings by way of example represents a recording apparatus such as used more particularl for vehicles, either horse-drawn the interior the casing being shown in vertical sect-ion.

Figure 4 is a bottom plan of'that portion of the apparatus containing the marking and counting mechanism.

7 F 1 4 represents a perspective view of the evice for imparting the movement of the driving shaft to themarking and, count- 'ing mechanism.

igure 5, represents a vertical sectional view, one part of which is taken below the lower front plate of the clockwork, the other part bein taken above the rear part of the same cloc work. i

Figure 6, shows a detail in enlarged scale. The entire arrangement is contained in a flat cylindrical casing 1 which is closed by a cover 2 rovided with a window 3. The cover is astenedto the casing by means .of a hinge 4 and is locked-at the opposite side by means of a bolt or similar locking device which may be sealed in a suitable manner. The casing contains two works, the lower one of which serves for operating the two marking devices and the counting device,

whereas the upper one serves for the tr ansort of the recording dial or chart. he ower works, whichare illustrated more par ticularly in the Figures 2 and 5 in front elevation, and in the Figures 3 and 4 in side elevation, are arranged between the plates 6 and 7. The lowerworks are distinguished byan extremely simple construction which permits of arranging ithe'two marking devices within close proximityof each other, this greatly facilitating the observation.

The upper plate 6 of these works is provided wit an aperture 8 for the driving ratchet wheel 9, an arced a rture 10 for the main marking device'whic .in the present case is designed'asa unch, and a small cir: cular aperture 12a mitting' an additional punch'having a blunt head or beating pin 13 which is'set-in motion by the vibrations imparted to the device. Fig. 6 shows. the beating head 13 of the pin 13.

, Asillustrated in Fig. 1, the marks of the punch 11 serving as main marking device and perforating the chart 14 from the rear, appear in the known manner in the shape of zlg-zag curves, whereas the pin 13 acts 1n such manner on the recordin chart, that the latter becomes embossed, an the marks appear on the outer rim of the chart where they form themselves in a circle-segment for the period during which the recording device is exposed to vibrations.

The recording chart 14 is held against the perforating movement taking place from the rear to the front, by a horn 16-one side of which comes up close to the perforations without, however, covering them over, so that as Fig. 1 shows, the markings are clearly visible from the very moment they are produced. The horn 16 is held to the upper plate 6 by means of a support 17 (Fig. 4) in such a manner that it is pressed u ward automatically under the influence o a spring 18 whenever the cover of the casing is opened. Only when the cover is pressed down, the spring 18 is depressed, the horn 16 being thus brought correspondingly nearer to the recording chart.

The upper late 6 has inserted in it the counting mec anism 19, the numbers of which appear inside a correspondingly large sector of the recording dial 14 (of. Figs. 1 and 2). This arrangement permits of placing also the. counting mechanism inside the casing and avoiding the transparent recording charts and pressing-down arrangement hitherto used.

- Into the casing 1 a rotating spindle 20 is introduced from below, this s indle being connected to a flexible driving s iaft through the intermediary of which it is set in motion from one of the wheels of the vehicle. Inside the casing the spindle 20 is fitted with an eccentric 21 (Figs. 4, 4 and 5) which turns within a forked lever 22. This lever turns on a shaft 23 and is rigidly connected to a lever arm 24, the latter carryin a ratchet feeding pawl 27 which is pivoted on the spindle 25. This pawl engages under the influence of a spring 26 the teeth of the ratchet wheel 9 which, on the other hand, is also under the influence of a retaining pawl 28. When the forked lever 22 is moved up and down by the spindle 20 and eccen trio 21, the pawl 27, which is pivotally mounted on lever 22 in a transverse vertical plane through pivot point 23, follows the rocking motion of the lever. Since pawl 27 is pivoted as shown, so that it swings itself in a plane at right an les to the operating plane of lever 22, in 0 er to enable it to be pressed into engagement with ratchet wheel 9 by means of spring 26, this pawl will feed the ratchet wheel step by step in clockwise direction (see Fig. 4") when lever 22 is rocked by eccentric 21. The ratchet wheel 9 may easily be taken off its shaft 30 on which it is fastened, by loosening two small screws 29 (cf. Fig. 2). The shaft 30 is rotatably supported in a plate 31 and in the lower plate 7 and carries a worm 32 and a cog wheel 33 the teeth of which run in axial direction and are faced obliquely only on one side. Into the worm engages a gear wheel 34 which is fastened on the shaft 35 mounted rotatably below the upper late 6. This shaft carries a second gearw ieel 36 which, in a manner not re )resentcd on the drawing engages rearwardly in the first driving wheel of the counting mechanism 19. Finally, a cylinder 37 is fastened u on the shaft 35, the end surface of which is faced off obliquely. Against this oblique surface a. roller 38 presses, this roller being fixed to a bell crank 40 supported on a shaft 39 between the two plates of the works. The other end of this bell crank contains the punch or needle 11 which passes through the slot 10 of the plate 6 and owing to the cooperation of elements 37, 38 describes the previously mentioned curved reciprocating movement corresponding to the marks on the recording chart 14. The coupling of the driving worm with the counting mechanism and the curved guide for the main marking member 11 by means of the shaft 35 is of particular value for the simplification of the entire 0 rating mechanism and ermits of placing tie two marking devices irectly ad acent to each other for effecting the marks on the recording chart.

' A cam 41'acts in con unction with the cog wheel 33 fixed upon the spindle 30, this cam being fastened to a plate 42 (cf. Figs. 4 and 5). This plate is rotatably mounted on a pivot 45 in two projections 44 of the lower plate 7 arid is under the influence of a leaf s ring 46 which tends to hold the plate in t e center sition as represented on the drawing. en the worm wheel 32 turns in the direction of the arrow, the cam 41 and, with it the plate 42 are pressed downward thus putting the spring 46 under tension. However, whenever the cam tilts over one of the co s of the wheel, it dro s into the next gap hitting the free end of the rforating lever 40 with a strong blow t us forcing the punch 11 through the registration chart.

The easily removable fixture of the ratchet wheel 9 has the-advantage that the recording apparatus may be very'conveniently adjusted to the diameter of the driving road wheel by simply exchanging the readily accessible ratchet wheel. The a rture 8 in the upper plate 6 is made so urge that ratchet wheels for all customary sizes of road wheels may be fitted.

The beating mechanism 13 set in motion by vibrations of the entire registering apparatus, is arranged at the end of the shorter m of e bell c a k 47, the latter being tween the teeth, the p ate 42 rotatabl mounted on a spindle 48 and being provide at its other r arm with a weight 49 (Figs. 3-5). Or inarily, a spring 50 pulls back the pin 13 in opposition to.

7 effect. These marks are quite independent I of the record of the main marking device tire that it respon and, in the example illustratedv in Fi 1, convey the information that the car has been run uninterruptedly from 10 a. m. till 12.30 p. m. and then intermittent] up to 6.30 p. m., and further in the evening from 8.15 till 9.30 m., and again from 11.45 p. m. till 2 oc ock in the morning, without the main marking device having made any record at all; it may, therefore, be concluded that the drive of the main marking device has in some manner been put outof action during the last two periods. This vibratory marking device ma also be made so sensieven' to the vibrations of the on he of a motor car running idle whereby it is possible to obtain a record on the recording chart of the time during which the engine is running while the car a 'thenumbers signifying hours printed thereis standing. I

The clockworks 51 serving for the trans port of the registration chart 14, is held between two plates 52, 53 (cf. Figs. 2 and 3). The upper plate 52 carries another late 54 over which the interior aperture 0 the. recording dial 14 fits exactly. Two rejections or lips 55 of this plate (cf. ig. 1) provide a support for the front of the recording chart so that it cannot slip of. The clockwork 55 drives by means of an exterior toothed rim 56 and t-hrou h the intermediary of a train of gear w eels not represented on the drawing, its balance 57. Its winding ratchet wheel .59 located at the lower surface and working in conjunction with the ratchet pawl .58, is fitted with a lever 61 (Fig. 5) which is kept under tension by a spring 60. When the clockwork iswound up by means of a key laced over the square winding arbor 62 (cf. ig. 5), the

lever 61 will first strike against a stop 63 whereby its spring is put under tension. During the further rotation of the ratchet wheel 59,,the lever slips ofl' this stop and strikes against a bell crank 65 rotatably mounted upon a spindle 64, whose other, resilientarm moves past the outer rim of the balance 57 in the manner indicated by the dotted arrow. thus carrying the latter along with. it. In this manner. the clock movement is started automatically during the winding-up operation and a stoppage of the clock is thereby prevented...

The upper portion of the clock movement is provided with two toothed rims 66 and 67 engaging a pinion 68 which serves for the transport of the recording chart 14 (Fig. 2). This pinion is mounted in the plate 52 slidingly on a pivot 69 and is provided with. a hub 70 which is provided with an annular oove 71. Into this. groove enga es a for ed lever 72, the opposite end of w ich is guided by means of a pivot 73 in a slot of the plate 52 and is connected to a head 75 protrudin beyond the slot. Thelever 72 is provide 76 into which engages a resilient counter lever 77. A spring 78 keeps the forked end with two catches is moved in one or other direction, the a pinion 68 is made to engage either with the outer rim 66 of the clockwork or with the inner toothed rim 67. Accordin ly the wheel 68 will be madeto turn at ifierent velocities, the dimensions bein made such, t of the center of t e recording chart 14, that the latter when driven from the'toothedrim 66, moves at double the circumferential speed of thatimparted by v the toothed rim 67.]

In the example illustratedon the drawing the recording chart is transported by the interior toothed rim 67 and, corresponding to on, makes one revolution per day. When the driving pinion is shifted toward the interior by means of the knob 75, the circumferential speed is doubled and it is'possible to'use a recording chart for 12 hours. With due consideration for the corresponding time units, also the same recording dial may be used.

A check as to which of the two speeds has been used during the recording is possible by the pinion 68 also producing a mark during its operation, this mark being made near the inner or outer edge of an interior annular strip 79 of the recording chart. The punctuation indicated on the interior side of the annular surface would mean that the same recording dial has also been run for a.

certainv period at double the speed which would indicate a double utilization of the recordin dial. V

In 0 er to provide for an effective coupling of the recording dial 14 with the driving pinion 68 and, at. the same time for producing the marks previously mentioned. the abutmentshown in Figs. 1 and 3 has been provided. This consists of a lever 80 mount;

ed rotatably within the plate 54,. the short interior end of which is acted upon by a spring 81 in such a manner that this spring tends to retain this lever in the depressed position as represented, or else in an upturned position forward. A cylinder 82', is rotatably supported on a spindle 83 within an aperture 82 of the lever 80. This cylinder is provided with two slots 84, 85, one or another of which, according to the position of the driving pinion (38 registers with the latter thus pressing the recording chart down upon the teeth of the pinion. Notwithstanding the pressure of the cylinder 82 being comparatively light. the coupling of the recording chart with the driving pinion is absolutely positive and secure.
