Application tiled-Enne 8, 19GB. Serial No. 5913,571.
To all whom it 'may concern:
Be it known that I, EMANUEL Geenen HALvonsEN, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Automatic Alarms, of which the following is a full, clear, and exact description. I
This invention relates more particularly to an automatic alarm for automobiles.
.The primary object of the invention is to provide a simple and efficient device which may be attached conveniently to an operative part of an automobile or other vehicle in such a way that when the vehicle exceeds a certain speed an alarm or plurality of alarms may be sounded so as to notify the attendant of the vehicle and other persons that the speed of the vehicle is in excess of that permitted by law.
Another object of the invention is to provide a simple and efficient device which may be made to automatically ring a bell or operate pneumatic means employed in connection with the usual horn of automobiles.
A further object of the invention is to provide a simple and efficient device which may be used for various purposes.
With these and other objects in view, the invention will behereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.y
In the drawings, Figure 1 is a section through the casing of the device, showing in elevation one form of alarm mechanism embodying my invention; and Fig. 2 is a front elevation of the device. v The casing 10 may be of any suitable construction and may be attached in any convenient location to an operative part o f the vehicle, and said casing may be provided with a bearing 11 at one end thereof and a. bracket 12 at the forward part thereof in which is held to rotate a shaft 13, and on said shaft 13 is a pulley or other element 14 by which the vsaid shaft may be rotated from some rotary part of the vehicle. A disk or device 15 is held at one part of the shaft 13 and at or near the other end of theshaft is held a device 16 and connecting said devices 1:5 and 1G are a plurality of spring members 17 to each of which may be attached a weight or other part 13 so thatx when the shaft 13 is rotated the tendency of the weights 18 is to throw the spring menibers 17 outward, thus causing the device 1G to Slide along the shaft 13 toward the disk or device15. The device 16 has a sleeve portion 19 projecting outward from a disk or collar 19a and on said sleeve are projections or engaging parts 20. This sleeve 19 is slidingly held to rotate with the shaft 13 by means of a spline and feather or otherwise so that when the speed of the shaft is at a certain rate, the projections 2() will rotate without engaging any other element, but if the speed exceeds a certain rate the said engaging parts 20 are moved inward along the shaft 13 into line with the handle 21. The handle 21 may be pivoted at 22 to the casing 10 and is normally forced in one direction by av spring 23, and said .handle or lever 21 has a hammer 24 which is adapted to engage a bell or other sounding element 26 in order that an alarm may be sounded indicatingthat the vehicle is travcling at a certain speed as for example that permitted 'by law, and in additionto the alarm 25. I may lprovide a pumping element 27 Aadapted to be connected in such a way as to blow the usual form of horn or other alarm. One manner of connecting the pumping element 27 with the horn or alarm is shown in Fig. 2 wherein 27 indicates the horn connected to the pumping element by means of the pipe 27. As shown, the pumping element 27 has a cylinder 28 in which is movably held a piston 29, and this piston is connected to the rod 30, which by a link 31, is connected to the operating lever 32. The lever 32 is pivoted at 33 to a bracket 34 and said lever is normally out of the path of lmovement of the engaging parts 20, and is engaged thereby when the speed of the shaft is sufficient to move the device 2O into line therewith, the said lever 32 being moved in one direction by means of a spring 35 or otherwise. I
A spring 3G is arranged around the shaft 13 and has one end resting against the disk 19"t of the device 16 and its other end against a-collar 37. The collar 37 may be held to the'shaft 13 by a set screw 3S, and this said collar isadapted to be adjusted along the shaft 13 so thatthe tension of the spring 3G may be varied in order that the speed at which the shaft is to rotate before the alarm is sounded may be also varied. By adjusty thereby requiring a greater speed of the shar't 13 before-the device20 will be made.`
,. be such that ,the/mechanism will not be offered to the movement of the device 16` to enga e the levrj'of the alarm 25 or the lever o1: the pumping element forming a part of the second alarm. y It'will be understood that the casing)- may e accessible except to 'certain persons, as for example, the police authorities so that said mechanism cannot be tampered with lto permit a greater speed to be obtained without sounding analarm.'
From the -foregoing 'it' will be seen' that a simple and eiicient device is provided which Vmay befreadily attached to an automobile or other vehicle. in such a way that the speed of the .vehiclema be readily ascertaine by the attendant or y others, thus notifying a 'policeman ori'other person that ,the vehicle.
is exceeding the speed permitted by law;
that simple means 1s provided whereby the. alarm may be sounded; that said 'device may.,
be used for various purposes; and that said device maybe made to sound one or more alarms.
-` Having thus described my invention1 I claim as new and desire to secure by Letters Patent 1. A Adevice of the characterdescribed,
n comprising a'" casing, a rotary vshaft mounted torotate within the same, a movable engaging device carried by s aid shaft, means for ing the spring 36 a greater resistance may moving said device on the shaft, means adjustable on said shaft whereby the posit-ion of said engaging device is determined by the speed of said shaft,l aK pumping element adapted to operate 'a`signal, and a lever for operatingsaid pumpin element,l said lever leing operated vby said movable engaging evice. Y'
. 2. A device of lthe character described,
comprising a casing, a rotary shaft mounted to rotate withinthe same, a movable'engaging device vcarried by said shaft and having its position determined .bygthe speed of said shaft, means for moving said device on the shaftfa pumping element, and means i operated by said movable -engaging device for operating said pumpingelement.-
3. A. device of the 'character-'described,
