AUTOMATIC DATE- RECORDING INDICATOR OF EXCESS SPEED.

Application filed Kay 21, 1920. Serial No. 383,035.

To all whom it may concern:

Be it known that ATILIO Rnnoni, subjectof the King of Italy, residing at No. 2272 Leandro N. Alem Street, Buenos Aires, Argentina, has invented certain new and useful Improvements in Automatic Date-Recording Indicators of Excess Speed, of which the following is a specification.

This invention relates to an improved apparatus designed for the purpose of recording excessive or decreased speed of moving mechanism.

The primary object of the invention is to furnish an apparatus to be used in connection with moving mechanism for the purpose of recording the period of time during which the speed of saidmechanism is execs sive or reduced.

The improved apparatus also includes devices for recording the time when the excessive or reduced speed is commenced and the time when the excessive or reduced speed is discontinued. The recording mechanism willindicate the day and the time of day when the excess or reduced speed occurs.

A further object of the invention is to furnish improved means for registering the number of times which an excess or reduction of speed occurs in connection with machinery, and a further object is to provide an audible indicator for notifying the operator when the excess or reduced speed occurs.

A mechanism of the above character is particularly useful in connection with motor vehicles for furnishing the law enforcing authorities with data for use in prosecuting speed violators. The present mechanism may be placed in a sealed case, which may only be opened by the police authorities and by opening this case an authorized person can ascertain when speed violations occur; the period of'time during which the violation took place; and the number of times of such violations during a given period.

lVith the foregoing objects outlined, and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings and moreparticularly pointed out in the appended claims.

Referring to the drawings:

In the drawings, 1 designates a rotatable member, the'excess speed of which is adapted to be recorded by my improved mechanism. In the present instance this member 1 is an internal gear arranged on a motor vehicle wheel 2 and it drives a pinion 3 connected to one end of'a flexible shaft 4 arranged within a casing 5. The other end of the shaft 4 extends into the mechanism casing 4 and is provided on its inner end with a fixed gear 6, which drives a gear 7 fixed on a shaft 8. This shaft is rotatably mounted in a bearing 8 and carries a gear 9 which is loosely mounted on the shaft. A spring 11 is arranged on the shaft 8 between the gear 9 and gear 7 and it normally tends to cause the gear 9 to rotate with the gear 7. The pressure of the spring is so regulated that under normal operation it will cause the gear '9 to rotate with the shaft 8, but when the gear 6 is driven above a predetermined speed, the spring will slip over the face of the gear9 so that said gear will not permit ofthe excessive movement. In other words the spring 11 and gear 9;.function in the same manner as a friction clutch.

The gear 9 is preferably of the worm type, and it drives a. similar gear 9* fixed at the lower end of a shaft 10 which is rotatably mounted in bearings 10-. A'colla-r 10 is fixed to the lower portion of the shaft 10 and a collar 14 is slidably mounted on the upper portion of said shaft. These collars are connected together by links 13 and s the bell 96 weights 12, thus forming a governor designed to lower the collar'l4 when the speed of the shaft 10 in increased. A collar 18 is slidably mounted on. the shaft 10 and may be secured in adjusted positions by means of a screw 18. A coil spring 16 has one of its ends bearing against an anti-frictionring 17 and its other end bearing against the collar 18, and this spring tends to hold the collar 14 in its raised position and to counteract the action of the weights 12. A disk 15 is fixed to the collar 14 and moves vertically with said collar. Said disk is engaged by the edges 20 of a fork 19 which is fixedon a shaft 21 rotatably mounted in a bearing 22 fixed to one end of alever 23 which is pivotally mounted at 24 on one side of the casing 4. When the governor moves up or down, it causes the disk 15 to rise and fall and the disk actuates the fork 19 to cause the lever 23 to swing about its pivot 24. Movements of the lever are utilized for the purpose of operating the printing plunger 46, the feeding of the paper 49 and the inking ribbon 50, the actuation (if-the counting wheels 87 and for the operation of The transmitting mechanism for these purposes will now he described.

The lever 23 is provided at one end with a toothed sector 25 which during movements of the lever engages an actuating gear 26 fixed on a shaft 29. This shaft is mounted in bearings 29 carried by a support 29 which depends from the top of the casing 4*. The shaft 29 is-provided with fixed gears 27 and 28, the former of which drives an idle gear 30 (see Figs. 9 and '10) mounted on one of the bearings 29, and the latter of which drives a gear 35 loosely mounted on a shaft 36 that is rot-atably mounted in the bearings 29.

The idle gear 30 meshes with a gear 31 which is also loosely mounted on the shaft 36. The gear 35 has its hub provided with teeth 34 and the gear 31 has its hub provided with teeth 32, as best shown in. Figure 10. The teeth 32 and 34 are adapted to be alternately engaged by the teeth 33 provided on the ends of a clutching spool 34 which is slidably mounted on the shaft 36 but is prevented from-rotating on said shaft by means of a spline 34. As the member-34 rotateswith the shaft 36, it will be understood that when it is engaged with the teeth 3.2 of the gear 31 it will be in position to be driven by the gear 27, while when it isin engagement with the teeth 34 of the gear 35.

the shaft 36 will be in position to be driven by the gear 28. Consequently when the toothed sector 25 is swun upwardly by a depression of the disk 15. t 1e gear 26 will be driven in a clockwise direction. At this time the member 34 is in engagement with the teeth 32 and consequently the shaft 36 will also be driven in a clockwise direction. Controlling means hereinafter described, are provided for the purpose of shifting the member 34 and it is so arranged that it will shift the member 34 when the sector 25 descends. Consequently when the member 34 is in engagement with the teeth 34, descending movement of the sector will cause the gear 26 to revolve in an anticlockwise direction and this will cause the gear 28 to drive the gear 35 in a clockwise direction. As a result the shaft 36 will be driven in a clockwise direction. each time the member 26 is engaged by the sector 25, whether said sector engages the gear 26 from below or above.

The shaft 36 carries fixed cams 37 and 38, the former of which actuates the printing plunger 44 and the latter of which actuates the pivoted lever 39 which effects the shiftin of the clutch member 34.

The lever 39 has one of its ends connected to a pivot pin 39 and its opposite end rests on the cam 38, which functions to raise the lever 39. A spring 39 is provided for the purpose of moving the lever 39 downwardly. An arm 43 is fixed to the lever 39 at the point 43 and this arm, when the lever 39 descends is adapted to strike a double ended lever 42 which is pivoted at 42 on a support 42*. The lever 42 carries upwardly extending diverging pivoted arms 41 that engage slots provided in arms 41 which depend from a member 40, mounted on a. horizontal pivot 40 carried by a support 40. The member 40 is provided with vertical arms 40, forming a fork which engages the clutch 100 member 34*. By this construction it will be understood that the lever 39 effects shifting movement of the member 34 in onedirection, and the member 34 is moved in the opposite direction by-means of a spring 42 105 which has one of its ends connected to the support 42 and its other end connected to the lever 42. This spring tends to hold the lever 42 in engagement with a stop 42 prov vided on the support 42*. Y

From the foregoing it will he understood that descending movement of the disk 15 will cause ascending movement of the lever 23 and sector 25. If the speed of the vehicle is not excessive, then the sector 25 will 115 not rise sufficiently high to engage the .gear 26 and may oscillate between said gear and the lower position of the sector 25. If the speed is suflicient to cause the sector 25 to engage the gear 26, but insufficient to cause 120 the gear to turn far enough to move the shaft 36 a complete revolution. then the hammer 46 will not lie actuated. When the speed is such. however. that the sector 25 rises above the gear 26, said sector in its move- 125 ment past the gear 26 will cause the gear 26 to drive the shaft 36 a complete revolution, and this will cause the cam 37 to make a complete turn andrelease the plunger 44 so that the hammer46 will strike the paper ribbon 49 in order to impress the latter. As long as the'sector 26 remains above the gear 26, the hammer will remain in the position shown in Figure 2, but as soon as the disk 15 rises a sufiicient distance to move the sector 25 downwardly below the gear 26, said gear during this movement will again drive the shaft 36 a complete revolution, so that the cam 37 will again actuate the hannner 46. It will therefore be seen that the paper ribbon will be stamped once when the speed has'increased sufficiently to move the sector 25 above the gear 26. and will be stamped again when the speed has decreased to the point where the sector 25 moves below the gear 26.

Should the sector 25 be in enga ement with the gear 26 and the speed be sue as to cause the sector 25 to oscillate in engagement with said gear 26, then the cams 37 and 38 will merely oscillate and will not move sufiiciently far to actuate the hammer 46 and the arm 43.

The printing plunger 46 has its casing 47 carried by a support 47 as best shown in Fig. 5, and a spring 48 is arranged in this casing and bears against a collar 45 fixed on the stem 44. This spring functions to force. the plunger 46 toward the ribbons 49 and 50. The stem 44 is provided with an angular extension 44 which engages the cam, 37 and it will be understood that on each complete revolution of the cam 37 the plunger 46 will be operated. At a certain inclination of the lever 23, corresponding to a predetermined speed of the vehicle, the extension 44 of the plunger stem reaches the end of the cam 37 and the plunger is forced against the paper ribbon 49 under the action of the spring 48. At the same time the mechanism for shifting the member 40 comes into operation to cause the cams 37 and 38 to rotate in a clockwise direction only.

Wounted in the casing 4 is a clock 52 which drives a. set of type wheels indicated generally by the reference character 51 in Fig. 4. These type wheels are set by the mechanism of the clock and they indicate seconds. minutes, hours and days. The numbers of the type wheels 51 are adapted to print on the paper strip. For instance in the numbers shown set in Figure 4. eading from left to right, 1230 indicates days and 23.59 indicates hours and minutes, or, counting from the date when the apparatus was set in motion the 1230 days give the date. this being the third year. fourteenth day of May and the numerals 23.59 indicating the time on that date. this time being 11.59 P. M. It will be noted that the ribbons 49 and 50 pass between the plunger 46 and the type wheels 51 so that each time the plunger is operated it will stamp on the strip the date and time of the excess speed of the vehicle.

In order to provide a continuous record a shaft 74.

it is necessary to advance the ribbons 49 and 51) after each impression has been made and to accomplish this the ribbons are mounted on movable reels. As best shown in Fig. 2 the paper is fed from the reel 68 which is mounted on a rotatable shaft 69 and is removably held in place by a cotter pin 69.

'One cheek of the reel 68 is provided with peripheral teeth 68" for the purpose herein-. after described. The paper strip 49 passes from the reel 68 over rollers 77 to the winding reel 76. This reel is removably mounted by means of a cotter pin 67 on a shaft 76 and one cheek of the reel is provided with peripheral teeth 76, which. mesh with the teeth 68 for the purpose of driving the reel 68. -The shaft 76 is provided with a fixed gear 66 meshing with an idle gear 65 that is driven by a spring operated gear 64. The tendency of the spring operated gear 64 is to cause winding of the paper ribbon 49 on the reel 76 but this winding movement is regulated by means which will now be described. The ribbon 49 in its passage from the reel 68 tothe reel 76 passes over a drum 61 having teeth 61" which engage perforations in the ribbon. Theseteeth prevent feeding of the paper until the drum 61 moves. To accomplish movement of this drum the shaft 62 on which itl is fixed is provided with a fixed escapement wheel 57 engaged by an escapement 58 that is pivotally mounted at 58 on a suitable support within the casing. The escapement lever is provided with a fixed arm 58 that is engaged by a link 60, which is pivotally connected at 59' to a swinging arm This arm is connected. by a link 54 with the swinging lever 23. the points of connection being at 53 and 56. The swinging arm 55 is mounted on a shaft 94 which extends across the casing 4. It will be seen that each time the lever 23 is operated, the members 54, 55 and 60 will effect operation of the escapement lever 58 and will advance the escapeinent wheel one tooth, and then the spring operated gear 64- will come into play and cause winding of a small amount of the paper strip.

It is also necessary that the inking strip 50 be intermittently fed to bring a new inking surface into operation at each actuation of the plunger 46. To accomplish this the inking strip is mounted on a feed reel 72 that is removably fixed to a shaft 73 by means of a cotter pin 73. The inking strip passes from the reel 72 over idle pulleys 78 and is connected to a winding drum which is fixedly mounted on a shaft'71 by means of a cotter pin 71. The shaft 71 isprovided with a gear driven by av gear 74 fixed on The gear 74 is driven by a gear 63 fixed on the shaft 62. so that movemounted at the end of the lever.

. For the purpose of counting the number of operations of the foregoing mechanism so that a record may be kept of the number of times when the speed limit has been exceeded, ordinary counting wheels 87 are provided. These counting wheels are mounted on a shaft 88 carried by arms 89 extending from one side of the casing 4 For the purpose of operating these wheels, a link 80 has its upper end connected to the swinging arm 55 and its lower end connected at 81 to a lever 82 which has one of its ends pivotally connected at 83 to a bracket within the easing 4*. The lever 82 is provided at its free end with a pawl 84 which is pivotally A tailpiece 86 is provided on the pawl and bears against the lever for the purpose of preventing the pawl from swinging in an anti-clockwise direction beyond a predetermined extent. A leaf spring 85 is provided on the lever 82 and bears against the upper face of the pawl for the purpose of yieldingly holding the tailpiece 86 in engagement with the lever 82. This pawl is designed to engage teeth 90 fixed on one side of one of the wheels 87 and it will be understood that as the lever 82 swings upwardly the pawl 84 will engage one of the pins 90 and cause actuation of the counting device. As the lever 82 moves downwardly the'spring 85 will permit the pawl 84 to swing in a clockwise direction about its pivot so that the pawl may pass by one of the pins without turning the wheel, to which the pins are connected, in an opposite direction. The pins 90 are also engaged by a pawl 91 which is pivotally mounted at 92 on a bracket within the casing 4 This pawl is engaged by a leaf spring 93 which tends to force the same in an anti-clockwise direction but yieldingly permits movement of the pawl in a clockwise direction. Consequently the wheel having the pins 90 may rotate in an anti-clockwise direction but is prevented from rotating 'in a clockwise direction by the pawl 91.

For 'the purpose of providing an audible signal to notify the operator that the speed limit is being exceeded, the swinging arm 55 is designed to-operate over atcurved insulated segment 95 having ametallic conductor 96. An electric wire 94 is connected to the contact 96 and to a bell 96*. Another wire 94 is connected to the shaft 94 and to a battery 94*. Still another wire connects the battery to the bell, and it will be understood that each; time the arm 55 engages the contact 96 an electric circuit will be completed through the bell 96 and this will cause a signal to be given.

From the foregoing I believe that the construction, operation and advantages of the invention may be readily understood by those skilled inthe art, and I am aware that mechanism for moving said plunger in an opposite direction only when a predetermined speed has been exceeded.
