SPEED-INDICATING DEVICE.

Specification of Letters Patent.

Application filed OGMbeI 14, 1921. Serial No. 507,671.

To all whom it may concern:

Be it known that we,'Jos VIDAL BOSQUE aIId PANT'ALEON Gino Y (JAsAfiAs, both citizens of the Republic of Cuba, and residents of Habana, Cuba (whose postal addresses are, respectively, No. 16 Prado Street and No. 20 Refugio Street, Habana, Cuba), have invented certain new and useful Improvements in a Speed -Indicatin Device, of which the following is a speclfication.

This invention relates to a speed indicating device and its main object is to provide an apparatus of this kind which is preferably applied to vehicles, particularly to automobiles, which device is of very simple construction and efficient operation, its attachment to a vehicle not affecting the appearance of the same.

A further object of the invention is to provide an apparatus indicating by means of a graphical mark which is permanently marked if the vehicle surpasses a maximun speed assigned to it and at the same time this mark or signal is combined with an acoustic signal which immediately Zannounces the fault incurred in.

The invention is described with. reference to the figures of the annexed drawing, in which: a

Fig. 9 is an upper plan view in detail of a ring serving to malntain in position the scaled half-disc on the supporting disc.

Fig. 10 is atside elevation of a wheel equipped with the apparatus object of this invention. Y

This apparatus comprises a cylindrical casing 1 provided with a lid 2 hinged at 3 at its upper part and this 'lid2 has a glass 4 I and 13' is to look therethrough and a horizontal lug 2 diametrally arranged with respect to hinge 5. Below lid 2 is arranged a disc 6 which bears on an annular projection 7 from the inner face of the walls of casing 1 forming a horizontal partition dividing the casing 2 in a forward and rear chambers 1 1, the latter beinglarger than the former. Said disc 6 as detailed in Fig; 8 has its upper half 6 thinned to superpose thereon a semi-disc 8 provided with a scale 9 which in the case illustrated indicates from five to five the unity of speed used, whether this unity be a kilometer, a mile, etc.,v and is secured on disc 6'by means of a cut ring 11 illustrated in Fig. 9 and which is tightly fitted into cassemicircular recess 8' in the superposed scaled semi-disc S and passing therethrough is the end portion of square section-bf a shaft 12 on which is mounted a pillow 15 secured by a pin 15' there being integral with said pillow a horizontal arm 16 whose free end terminates in an integral collar 16 through which fits a pencil 17 whose point is in contact with the outer face of the scaled semi-disc 8 on the middle part of the radial lines formed by the scale 9 of the same. ber 1" of casing 1 being maintained gyratorily between two su porting. plates 13 and 13, of which the p ate 13 bears on the middle part of the inner face of the rear wall of the casing and .plate 13 is placed below the disc 6, plate 13 being secured to disc 6 and plate 13 likewise to the rear wall of easing 1 by screws 14. In the portion of shaft 12 comprised between the plates 13 xed a pinion 18 which meshes with a gear sector 19 in which terminates an angular arm 20 articulated to a pivot 21 ar- Shaft 12 extends into the rear chamweight 22 whose outer' face is curved and at 7 its free end has a connection for connecting an lend of a helical spring 23 whose other end is fixed to a screw 24'passing through a horizontal lug 26 fixedxto the inner face whistle of the horn, which is located at the narrower part of the same. This apparatus is provided with means for securing the same between two spokes of a wheel 31 as illustrated in Fig. 10, though it is obvious that this installation is for a mere demonstration to explain hereinafter the operation of the apparatus, as the same can be used in different connections in all those cases in.

which it is desired to determine by means of a permanent graphical signal or mark the maximum speed reached not only by a vehicle but in general by any machine or apparatus. To that effect from the center of the rear wall of casing 1 projects out an integral pin 33 whose end portion is thread. ed and in the same alinement with pin 33 project to one side and the other of the same two smaller pins 32 there being superposed on said rear wall a narrow and elongated supporting plate 34 which presents transversally to its middle part two holes 35 in which fit the pins 32 and a central hole 36 throughwhich passes the pin 33 said plate being maintained bearing in a flexible manner against the said rear wall by means of a helical spring 37 coiled around the ortion of pin 33 projecting beyond the p ate 34: against which spring is tightened a nut 38 threaded in the threaded portion ofpin 33. The plate 34 has at its ends holes 39 to fix same as'illustrated in Figure 10 between two spokes of a wheel 31 near the felloe thereof.

In the position illustrated in Fig. 10, that is with the apparatus presenting its semidisc 8 upwards, when the vehicle starts traveling, owing to the centrifugal force generated by the wheel through its rotation, the counterweight 22 will tend to follow that direction separating itself from the center of the apparatus causing to rotate around its pivot the angular arm 20 against the tension of spring 23 whereby the geared sector 19 will cause .to gyrate the pinion 1.6 fixed to shaft 12 in the direction indicated by the arrow in Fig. 4 and accordingly the indicating arm 16 carrying the pencil 17 will mark a line on'the semi-disc 8 as shown in Fig. 6. As the outward movement of the counter-weight 22 is directly in relation with the speed at which the vehicle travels .and the tension of the spring not *being overcome until surpassing a minimum velocity or speed, which in the present instance is indicated by 10 in the scaled disc 8 it is obvious that as the speed of the vehicle increases the arm 16 will advance further on the scale 9 and the pencil-17 carried by said arm will leave a mark on the scale which will end at the point of the higher speed reached by the vehicle during its travel, and owing to the fact that the casing 1 is closed and sealed it will not be possible to rub out the mark nor to substitute the disc 8 for another one without mark, and accordingly if an excess of speed has taken placeit will be easy to ascertain it by merely observing the end of the permanent mark made by the pencil 17 on the scale 9 of the semi-disc 8. At the same time, as the counterweight 22 is connected with the butterfly valve 29, the same will obturate the whistle 30 while the vehicle does not surpass the maximum speed permitted, but on surpassing this maximum speed, the valve 29 will open and the air suddenly admitted into the horn 30 will cause the whistle to blow, and this sound will indicate the fault of excess of speed incurred in.

When the vehicle may travel through places out of the cities where the use of the apparatus is not required, it will be suflicient to pull out the casing 1 to take out the pins 32 from the recesses 35 and to turn the casing along 180 on its pivot 33 until pins 32 are again inserted into recesses 35, causing counterweight 22 to move towards center of supporting wheel, and the mechanism becomes ineffective to record any increase of speed in the movement of the vehicle instead of flying outwards as it will be easily understood.

It is obvious that many changes can be made in the described construction, and also that this device can be applied to the vehicles by mounting it in the manner illustrated in the drawing or either in direct connection with the motor of the vehicle or in any other desired and proper manner, and also that this apparatus can be used to determine the maximum speed of rotatory machines and apparatus of various kinds, particularly when the same should not be operated above a maximum speed, and accordingly in view of all these possible changes we do not desire to be limited to the particular embodiment described in the annexed specification and illustrated in the annexed drawings, but

desire to protect by Letters-Patent all that which may fall within the scope of the appended claims.
