SPECIFICATION forming part of Letters Patent No. 778,4;51, dated December 27, 1904, Application filed February 4, 1904. Serial No. 192,012.

To all whom it may concern.-

Be it known that we. HENRY HARTLEY, a subject of the King of Great Britain and Ireland, residing at Clarence Chambers, Corporation street, and VINCENT CANOVA, a subject of the King of Italy, residing at Cropsall street, in the city of Birmingham, England, have invented certain new and useful Improvements Relating to Speed and Distance Recorders for Tram Cars, Motor-Cars, and the Like, (for which we have filed an application in Great Britain, No. 18,221, bearing date August 2%, 1903,) of which the following is aspecilication.

This invention has for its object to provide convenient and reliable means for automatically recording the speed of a tram-ear, motorcar, and the like throughout an entire trip or journey and also the stoppages and the distance traveled in miles, kilometers, or otherwise.

Referring to the six accompanying sheets of explanatory drawings, Figure 1 is an elevation showing one side, and Fig. 2 an elevation showing the opposite side, of a speed and distance recorder constructed in accordance with this invention. In each view the inclosing cover is removed, and Fig. 1 is partly in section. Fig. 3 is an elevation showing one end, and Fig. 4 a similar view showing the opposite end, of the recorder, while Fig. 4 is a plan of the same. Fig. 5 is an elevation showing one end, and Fig. 6 an elevation showing the opposite end, of a modified form of apparatus constructed in accordance with this invention, while Fig. 7 is a side elevation of the same with the front plate or frame part removed. Fig. 8 is an elevation With inclosing casing removed, showing the recorder governing or controlling mechanism. Fig. 9 is an elevation of the same, partly in section. Fig. 10 is an elevation, Fig. 11 a plan, and Fig. 12 an end view, showing the means for carrying the recorder governing or controlling mechanism upon a tramcar. Fig. 13 represents in diagrammatic outline a motor-car having our speed and distance recorder mounted thereon. Fig. 14 illustrates a portion of the log-sheet or register bearing a graphic record of speeds and disl tances produced by the mechanism illustrated in the accompanying drawings.

The same reference characters in the different views indicate the same or similar parts.

In the construction of the recorder in the form shown at Figs. 1 to 4, inclusive, there is arranged between side or frame plates, as a, a log-sheet or register, as I), to which motion is imparted by a clock or spring motor (2, adapted to rotate the log-driving roller (Z. Suitable gearing-wheels, as c, f, and r are arranged between the clock or motor 0 and the driving-roller (Z. The log-sheet or register in the form of a roll of paper or other material is mounted on a pin or spindle, as h, and is led to the driving-roller (I over a guide-roller, as 2'. A pressure-roller, as f, or other suitable device is provided to give the necessary grip of the paper on the driving-rollerd. End play or movement of the roll of paper on the pin or spindle /L is prevented by a hinged or pivoted guard-arm, as is, adapted to engage a slot in the spindle. A spring tension arm or brake, as Z, is also arranged in connection withthe paper-roll, as shown. Before starting on a journey with a car fitted with the recorder the clock is set in operation, and the paper or like log-sheet or register is thereby continuously moved at the predetermined rate. The log-sheet or register is suitably graduated for time, speed, and distance records, as shown at Fig. 14, and its rate of movement is such that its divisions shall pass under and be marked by the scriber, hereinafter referred to, exactly in accordance with the hours or periods represented. The marking or recording of the log-sheet or register is effected by means of a scriber, as 711, formed or arranged with a sleeve or socket mounted upon a spindle a. Along the said spindle is cut or formed a spiral groove or screw-thread, and within the said sleeve or socket part of the scriber m is a projecting peg adapted to engage such groove or thread. On one end of the spindle 12/ is fixed a small gear-wheel or pinion 0, engaging a sector, as p, which is rocked by the action of the governing or controlling mechanism, hereinafter described, and which is connected to the seetor by theflexible wire cables or transmitters, as q, and crank or lever r, so that the spindle a is caused to rotate or oscillate with the variations in the speed of the car, and thus to slide or reciprocate the scriber across the paper moving beneath it for making a recording-curve thereon. The flexible wire cables or transmitters 7 are kept taut by means of a spring, as a, coiled upon the spindle of the sector 7). A suitable supporting plate or tablet If for the log-sheet Z) is disposed beneath the scriber on. The scriherm is maintained in contact with the log-sheet by any suitably-arranged small spring or weight. To give warning to a driver when the speed of the vehicle has reached a dangerous or certain predetermined limit, the scriber m or the aforesaid sleeve or socket part of the same which slides upon the spirally-grooved spindle a is arranged to complete an electric bell-circuit, and so bring about the ringing of said bell. For this purposea pair of electric conductingrods, as a, are mounted between but insulated from the frame-plates rt and connected up to an electric battery and to the bell, such parts being arranged in any ordinary and convenient manner. On one of the said rods IL is adjustably mounted a spring contactpiece 4;, while the complemental part 1) of such contact-piece is mounted upon but insulated from the scriber m. The position of the contactpiece o is so adjusted that the predetermined limit speed of the car will move the scriberm to the required extent to complete the circuit. The scriber m records, by means of a curve or irregular line on the graduated log-sheet, the speed of the car and the number and lengths of the stoppages throughout an entire journey, as shown at Fig. 15. As such curve also indicates times or periods, the distance traveled by the car could be calculated therefrom; but for the more ready and convenient indication of the distance traveled in miles, kilometers, or otherwise another scriber, as w, is employed. This is preferably arranged simply to make a number of dots, as illustrated, on the log-sheet corresponding with the number of miles or kilometers traveled. The springarm :0 serves to support the scriber '20, the operation of which is effected through the medium of springs and linkage, as shown at Fig. 2. In its normal or initial position the scriber is held clear of the logsheet by the spring ;1 acting on the arm .2', while the slotted sliding bar 1 occupies the position shown by full lines; but with the movement of the car the crank or lever 2, which is connected to the operating mechanism, hereinafter described, by a flexible connection 3, acts upon and depresses the bar 1 against the tension of the spring @1 to a sutlicient extent to carry it below and clear of the pivotal trip-piece 5, as indicated by dotted lines at Fig. 2. After so depressing the bar 1 the action of the operating mechanism on the flexible connection 3 is released, so that the spring at is then set free to return the bar 1. On such return the said bar abuts against the trip-piece 5 and in pushing the same aside imparts an operative movement to the scriber M.

In the modified form of recorder shown at Figs. 5, 6, and 7 the log-sheet?) consists of a continuous band of paper or other material operated by the driving-roller (Z, placed in the position shown. ,Suitable guide-rollers, as '21, are employed and tension or pressure devices, as The flexible cord 9 for the operation of the sector 3) passes out through an aperture in one of the side plates (4, as shown, for connection with the governing or controlling mechanism. In combination with the distance-scriber '10 there is arranged a signalbell 6, which is sounded as each mile or kilometer is recorded by the distance-recording mechanism. \Vith such mechanism there is not employed a sliding bar, as in the previous example, the crank or lever 52 being made to act directly upon the trip-piece 5. Instead of or in addition to the means employed in the previous example for the sounding of a warning-bell on the attainment of a predetermined speed similar means are provided in the example now under consideration, so that for service with a car driven by a petrol or other internal-combustion motor the electric circuit of the ignition apparatus shall be broken and the motor thus automatically put out of action. The parts as described in the previous case can be suitably and readily modified in construction to adapt them for this purpose.

The recorder governing or controlling mechanism as adapted l'or motor-car service is illustrated at Figs. 8 and 9. In a fran'iing, such as 7, mounted in any convenient manner upon a suitable part of the car, is carried a spindle 8, having secured to the outer end of it a friction-wheel, as 9, adapted to be driven by contact with one of the road or other wheels of the vehicle, and at the inner end of it a gear-wheel 10. A governor, as 11, is rotated by the said gear-wheel 10. Connected to the free end of the governor is the flexible cable or transmitter which at its opposite end is connected to the sector hereinbet'ore described. The lateral movement of the free end of the governor 11 under the centrifugal action of the governor-weights 12 is thus transmitted to the sector 72 for the purpose hereinbefore described. The operating mechanism for the distance-recording scriber hereinbeiore referred to is also arranged within the casing7. Such mechanism comprises a cam 13, formed with or secured to the gear-w heel 10 and adapted to oscillate the extremity of a lever 14. Such lever carries a pawl 15, engaging the ratchet-wheel 16. The ratchet-wheel spindle carries a worm 17, gearing with the wormwheel 18. The worm-wheel spindle carries a pinion 19, gearing with the wheel 20, and se- IIO cured to the latter is a cam 21, adapted to operate a lever 22, to which is connected the flexible cable or transmitter 3 through the medium of the bell-crank lever 23 and flexible cord 24.

For service with an electric or other tramear the framing, such as 7, containing recorder governing or controlling mechanism such as aforesaid and also the operating mechanism for the distance-recording scriber, is mounted in conjunction with a friction driving-wheel 25, adapted for running upon the rail-track. The said wheel 25 is supported and maintained in contact with one of the rails in the manner illustrated at Figs. 10, 11, and 12 of the drawings. A depending arm or bracket 26, to which the wheel 25 and easing 7, with inclosed mechanism, are secured, is pivotally connected to a bar 27, which is hinged to the bracket 28. A spring connection, as 29, is provided between the bar 27 and bracket 28 to maintain the wheel 25 in contact with the rail. The bracket 28 is attached to one of the bogie-carriages, as 30, by means of clamping-plates and eyebolts, as illustrated. By the employment of such clamping-plates the necessity for drilling bolt-holes in the bogies themselves is avoided, and the adoption of eyebolts provides the requisite lateral freedom to the Wheel 25 relatively to the road-wheels of the bogie-carriages. A telescopic connection 31 is pivotally attached at one extremity to the bracket 28, as shown, and at the other extremity to the bogie 32. The arrangement of the parts as aforesaid provides for their automatic adjustment with respect to each other When the car is passing around curves or upon gradients. The wheel 25 is preferably made with a rubber or spring web or central part to provide additional flexibility to the system.
