COMBINED CYCLOMETER AND TIME-RECORDER FOR VEHICLES.

SPECIFICATION forming part of Letters Patent N 0. 600,811, dated March 15, 1898.

Application filed October '7, 1897- To all whom it may concern:

Be it known that I, FRED STREET, a citizen of the United States, residingin Philadelphia, Pennsylvania, have invented a Combined Cyclometer and Time-Recorder for Vehicles, of which the following is a specification.

My invention consists of an instrument in the nature of a combined cyclometer and time-rec0rder whereby will be indicated not only the distance traversed by a vehicle, but also the time occupied in traversing such distance or different fractional parts of the same.

In the accompanying drawings, Figure 1 is a face View of an instrument constructed in accordance with my invention, part of the dial being broken away to illustrate parts beneath it. Fig. 2 is a transverse section of the instrument without the clock mechanism. Fig. 3 is a section on the line 00 at, Fig. 2, with some of the parts in elevation. Figs. 4 and 5 are diagrams illustrating the action of part of the device, and Fig. 6 is a View of the recording-dial card employed in connection with the device.

My invention may be adapted to any available form of timepiece; but in the drawings I have only shown the casing and the hour and minute hand spindles of said timepiece, the spring and train of gearing being omitted to avoid confusion.

On the hour-hand spindle 1 of the timepiece is fixedly mounted a cam 2, which acts upon an arm 3 on a rock-shaft 4, mounted in suitable bearings in the casing of the timepiece, a coiled spring 5 acting on said rock-shaft 4, so as to maintain the inner end of the arm 3 constantly in contact with the face of the cam 2. On the rock-shaft 4 is another arm 6, which has a pin 7 passing through a slot in a segmental guard 9, which is carried by a spring 10, secured to the back plate of the timepiece-casing, said spring having a constant tendency to project the segmental guard outwardly beyond the point of the pin 7 through an opening in said back plate.

Secured to the timepiece-casing 11 is a rear casing 12, which has bearings for a worm wheel shaft 13, the latter having at its outer end a star-wheel 14 or other equivalent device adapted to be struck by a projection on the wheel of the vehicle, so as to be moved to the extent of one tooth or a fractional part of a $erial No. 654,379. (No model.)

revolution for each revolution of said wheel. The worm 15 on the shaft 13 meshes with the toothed periphery of an annular disk 16, which is mounted in suitable bearings in the back of the casing 12 and carries a pivoted frame 17, which is acted upon by a spring 18, the tendency of the latter being to move said frame to the forwardly-inclined position shown in Fig. 4, the frame being arrested, when this position is reached, by contact of a bar 19 on said frame with a spring 20, mounted upon the disk 16. The frame 17 carries a yielding presser-pad 21, which is preferably made in the form of a roller covered with yielding material and mounted upon a transverse spindle on the frame 17, as shown in Figs. 2 and 3.

Projecting inwardly from the casing 12 is a rib 22, and as the disk 16 is rotated in the direction of the arrow, Fig. 3, the upper portion of the frame 17 is brought into contact with one end of this rib, as shown in Fig. 4, the continued forward rotation of the disk 16 then having the effect of causing the frame 17 to be turned backwardly by the action of the rib thereon, so as to compress the spring 18, as shown in Fig. 5. As soon, therefore, as the frame 17 passes from under the control of the rib 22 the spring 18 tends to throw said frame forwardly again to the inclined position shown in Fig. 4, and in passing the highest portion of the arc traversed by it in making this movement the presser-pad 21 strikes the projecting guard 9 and thrusts the same inwardly, as shown in Fig. 2, so that said guard is pushed back beyond the point of the pin 7, carried by the arm 6, said pinpoint entering the yielding surface of the pad.

If the disk 16 is moved backwardly, the frame 17 will be depressed by the rear end of the rib 22, the spring 20 being compressed, so that when the frame 17 leaves the forward end of the rib 22 it will be swung upwardly by the action of said spring 20, so as to be in position to engage said rib on the forward movement. By this means back movement of the disk 16 cannot cause injury to the registering device or interfere with the proper operation of the same.

If a disk or sheet of paper, cardboard, or other puncturable material, such as represented at 23 in Fig. 2, is caused to traverse over the outer face of the guard 9, it will be punctured by the pin 7 whenever said guard is depressed by the action of the presser 21, and if said disk or sheet of paper or like material is mounted upon the minute-hand spindle 24 of the timepiece these successive punctures will follow a spiral course, their spiral disposition being due partly to the rotative movement of the disk 23 and partly to the transverse movement of the pin 7, caused by the action on the arm 3 of the cam 2, which is mounted upon the hour-hand spindle of the timepiece. Hence the space between any two successive punctures will represent an appreciable interval of time, which can be readily determined by properly graduating the face of the disk 23.

The method of graduation which I prefer to adopt is that shown in Fig. 6, on reference to which it will be observed that the circular strip or sheet has a spiral line dividing it into twelve convolutions, the spiral line being crossed by twelve equally-spaced and outwardlyextending curved lines concentric with the swing of the pin 7, whereby each of the convolutions is divided into twelve parts, each of these twelve parts being subdivided into five equal parts by means of other outwardly-extending and similarly-curved lines.

The twelve convolutions of the scale may represent the twelve hours from noon until midnight, or vice versa, each of the twelve divisions of each convolution representing five minutes and each of the subdivisions representing one minute.

The graduated dial is set on the minutehand spindle of the timepiece with proper reference to the dial of the samethat is to say, so that the pin 7 will traverse the line corresponding with the beginning of each hour.

Supposing that at the start of a trip the first puncture is formed at a, a second at b, a third at c, a fourth at d, and so on, this will indicate that the record began at six minutes past one p. m. and that the first rotation of the toothed disk 16 was made in six minutes, the next rotation in seven minutes, the

\ 1] ext rotation in four minutes,and so on. Thus if each rotation of the disk 16 represents one mile traversed by the vehicle to which the device is attached the indicator will show not only the number of miles traversed, but the time which elapses from start to finish and also the time taken to traverse each mile, and a permanent and accurate record of the trip will thus be produced.

The spring-guard 9 serves to hold the paper or other puncturable disk 23 free from engagement with the pin 7 at all times except during the fractional portion of an instant when the said guard is depressed by the presser-pad 21 as the latter swings forward after being released from the control of the rib 22. Hence the pin offers no obstruction to the free rotation of the recording-disk with the minute-hand spindle of the timepiece. This construction, however, is not absolutely essential to the proper carrying out of my invention, since it is evident that other means of marking the recording-disk may be adopted without departing from the main features of my invention. For instance,the disk may be carried by the hour-hand spindle of the timepiece and may contain but a single circle divided into seven hundred and twenty parts, each representing one minute during a period of twelve hours, and the swinging frame may carry an impression device of any suitable character which will mark upon the disk as it reaches the highest point in the arc of its swing after it leaves the rib 22. I prefer, however, to use both the hour and minute hand spindles of the timepiece for operating the recording device, because of the much greater area that can be covered by the recording-surface in this case and the greater accuracy of record thereby attainable.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination of a timepiece, a record-card holder actuated by one of the spindles of the same, a recording device, acarrier therefor consisting of a worm-wheel mounted in the rear of the timepiece-casing, a shaft having a worm engaging with said wormwheel, provision for operating said shaft by the rotating wheel of a vehicle, and means whereby said recording device is normally held out of contact with the record-card, but is permitted to move into contact with the same at one point in the movement of said carrier.
