To all whmn i may 007006770: 1 trical conductors between the controlling Be It known that we, CIIARLEs F. TAYLOR, mechanism and the recordingInstrument. a resident of Hartford, and FREDERICK J. Briefly stated, the mechanism shown in LAROGK, a resident of East Hartford, in the the drawings comprises a stylus which is car- 5 county of Hartford and State of Connecticut, ried on the uniformly advancing minutecitizens of the United States, have invented hand of an ordinary time-clock.

Consequently eight each completion of a predetermined distance punctures will be made for each mile traveled 20 run. and the speed ratio of the vehicle can be The invention has furthermore for its obreadily ascertained by considering the time ject the provision of mechanism in which which has elapsed between two succeeding the relative positions of the record sheet punctures. For instance, if a minute elapses and stylus are continuously and constantly from the time one puncture is made until the 2 5 changed by the advancement of one of said second puncture takes place the speed of the members through a chronometrieal device vehicle would be (for an hour) equal to sixty 7 5 as, for instance, a time-clock. eighths of a mile, or, in other words, seven. and

A further object of the invention resides in one-half miles per hour, but if two punctures the provision of an electromagnet for causshould occur during a minute the rate would o ing the stylus and record-sheet to contact and be I fifteen miles per hour running speed.

a base-board 12 is firmly secured. Mounted on this base-board is a time-clock mechanism T, which maybe of any desired construction and which comprises a staff 13 for actuating the minute-hand 14. Loosely mounted on the staff 13 is a sleeve 15, adapted to receive the quill of the hour-hand 16 and operated at a ratio of one to twelve by the usual .gear- Y train (indicated in a general way by 17) and disposed below a dial-plate 18, which is supported on the casing 10, as shown in Fig. 3, and has a comparatively small permanent dial 19 for use in connection with the hourhand 16. The dial plate 18 is preferably made of wood and supports on its upper face a stationary but removable record sheet or disk R, havinga central aperture correspond- 5 ing to the outside diameter of an annular flange 18, whereby it is properly located on I the dial-plate l8. The minute-hand 14 cdnsists in the present instance of a resilient bar supported on the i staff 13 and advancing therewith, and it has at its-outer end a soft-iron armature 14/, travcling over an annular field-plate 20, which is secured to the top of the casing 10 and serves to inclose a coil of wire 21 within an annular groove or recess 22, provided theretor. The ends of the Wire coil 21 are secured to termi-g n-als 23 24, respectively, and when a current 3 of electricity is sent through the coil the holdplate 20 will become magnetized and attract the armature 14, tlfus causing an indicator or stylus S, carried on the minute-hand 14, to puncture the record-sheet R. It may be 5 stated at this time that it is of course immateri-al what the nature of the stylus is may he, it being evident that any suitahle marking device, either with or without ink, maybeemg ployed in lieu of the puncturing-point herein illustrated and described without in any way i affecting the invention. Means are provided tor varying the resiliency of the bar 14 and tor locating the armature 14" within the magnetic zone of the liel d- .g plate 20, these means consisting substantially a of a stiff arm 25, secured on the minute-stall 1 1'3 and perforated at its free end to receive a screw 26, attached to said bar 14 and having a nut '27 for regulating the position of the minute-hand relatively to the arm 25. As above stated, the record-sheet is of sullicient capacity to cover twenty-four hours, I and by referring to Fig. 1 it be seen that 5 the record-sheet has radial lines dividing the 3 same into sixty minute-spaces and also a 'spif ral line .9, the outer end of which begins :at the i index-line i, disposed opposite the numeral XII of the permanent dial 1-9. The spiral line 8 indicates the pathof the stylus IS in its revolution around staff 13, each convolution approaching the center a predetermined distance, so that the succeeding hours may be readily distinguished. The first convolution covers the period fromsix 1a. m. to seven a.rn., 5

the second from seven a. hi. to eight a. 'm., and so on until the last convolution ends again at six a. in, thus giving to the record sheet a capacity of twenty-four hours, each subdivided into minutes.

Any suitable mechanism may be employed end of the screw 31 carries a pinion 44) in engagement with a gear 41., which may be :sta-

tionary, but is preferably mounted, for the sake of convenience, on the sleeve of the slowly-moving hour-hand, the organization being such as to cause the .ztylus-slide to. move inward about one-tenth of an inch during each revolution of the minute-hand. When the slide 36 has reached limit of its inward movement, the nut-section's 3.3 will be automatically disengaged fnom the .31 by engaging a conical portion 45 of the screw :31.

The entire thus tar described is mounted on and forms a part of the casing 10, which is provided with a cover-ring 5510, having a glass 51, which permits a plain view of dial and necordesheet iI-icloses the mechanism against injury.

The device whereby the magnet1coil'21 is periodically energized at completion of a one-eighth-mile travel of the vehicle is clearly shown'in Figs. 4 and 5., in which W denotes the vehicle-wheel giounnaled on the vehicle-axle A and carrying a tappet vor striker 60 of ordinary constnuction. The switch mechanism is mounted on a bracket 61, secured to the axle A, and comprises a star-wheel :62, secured upon a spindle 63, which is journaled in the bracket 61 and care ries a pinion .62 in enga ement with a gear i 63,mounteduponaspin 64.,also

in the bracket 61' and having a pinion 65 :secured thereto. ."lhe 6.5 meshes in a gear 66, which is loosely mounted for rotation on the spindle '63 and carries an insulated disk '67., provided with :a metallic strip 68, which constitntes a circuit-maker and serves :as a medium whereby an electric connection is established \once during each complete rotation of the (disk 67 and its gear between a pair of hrushscontacts 7:071, are normally insulated from each other .on an insulating-block 72, held on the bracket .61.. The gear 66 and disk :67 are prevented from longitudinal displacement on the spindle 63 TOO by means of a collar 73, and the ratio of gearing is in the present instance such that seventy-two rotations of the thirty-sixinch vehicle-wheel WV, equaling a travel distance of one-eighth mile, will result in one full rotation of the disk 67, therefore connecting the brushes 71 at the completion of each eighth mile and closing the magnetcircuit, which comprises brush 70, battery B, terminalv 23, coil 21, terminal 24, conductor 24, brush 71, and strip 68.

The actual work performed by our improved recorder and. the significance of the markings on the record-sheet can be readily ascertained by referring to Fig. 1, which shows a record of a trip, as follows: The vehicle started from H at 7.2.0 a. 111. The next nine-minute run to I shows twelve marks, which means three-fonrths of a minute used for each mark of one-eighth of a mile and a total distance of one and one-half miles traversed between 7.20 and 7.29 a. m. Now if it took three-fourths of a minute to run oneeighth of a mile, as the record-sheet plainly shows, it would take at the same speed six minutes to run one mile, so that we find that the vehicle ran at a speed of ten miles per hour between 7.20 and 7.29 a. m. and traversed a distance of one and one-half miles. Between 7.29 and 7.35 a. 111., a period of six minutes between I and K, we find sixteen marks, equaling a distance of two miles and showing a speed of one-eighth of a mile for each three-eighths of a minute, or a twentymile rate. Between K and L the time consumed was thirty minutes, (from7 .35 to 8.05.) Twelve marks mean a distance of one and one-half miles traversed, two and one-half minutes for each one-eighth of a mile or a speed rate of three miles per hour. From L to M it took from 8.05 to 8.08 a. m., three minutes, to accomplish four one-eighths miles at three-fourths of a minute each, showing a speed-rate of ten miles per hour. In a similar manner the distance of onefourth of a mile from M to N was covered between 8.08 and 8.09% a. m., equal to one and one-fourth minutes at a speed rate of twelve miles per hour. From N to O the distance is one-half mile, covered, in one and one-half minutes at the rate of twenty miles. From 0 to P it took seven minutes to travel three and one-half miles at a speed of thirty miles per hour. From P to Q is a distance of one and one-half miles, covered in six minutes at a '[ifteenanile rate. From Q to R nine minutes were consumed in traversing three miles at a twenty-mile rate. From R to T is a distance of two miles, covered at a tenmile rate in twelve minutes, and from T to U it took twenty-nine and three-fourths minutes to travel one and one-half miles at a speed rate of three miles per hour, the total distance from the starting-point H being seventeen and threefourths miles, and the time consumedwas from? .20 to 9.143;, a period of one hour and fifty-four and one-half minutes.

From the foregoing it is evident that our improved recording device preserves an accurate account of the performance of a vehicle during any one day, regarding the distances traveled between given points, the speed attained, and also the time of the day when the occurrences took place.
