Specification of Letters Patent.

Patented Dec. 26, 191G.

Application filed. April 21, 1914. Serial No. 833,404.

To all whom it may concern Be' it known that I, LESLIE E. Moons, a citizen of the United States, residing at Long Beach, in the county of Los Angeles,

State of California, have invented new and useful Improvements in Automatic Alarm Apparatus, of which the following is a specification.

This invention relates to an automatic alarm apparatus, and particularly pertains to a mechanism adapted to be mounted on automobiles to prevent theft of the latter.

It is the object of this invention .to provide an alarm apparatus which can be read-- ily attached to automobiles and power propelled vehicles, such as motorcycles, motor boats and the like, and which can be set to operate in event the vehicle is taken by an unauthorized person to sound an alarm and cut oil the motive power of the vehicle.

Another object is to provide an alarm mechanism of the above character which can be adjusted to operate to sound an alarm and stop the vehicle when the latter has trav ersed a predetermined distance, and which, when automatically operated,wil-l effectively prevent further propulsion of the vehicle.

A further object is to provide an alarm attachment for power propelled vehicles adapted to-operatewhen the vehicle has been moved a certain distance to sound-an alarm and to cut out the propelling mechanism, and in which adjustment can be effected, whereby the alarm will be sounded at any suitable interval before cutting out the motive power.

A further object is to provide a means for setting and adjusting the alarm mechanism and for throwing it in and out of an opera tive position, which is controlled by a permutation mechanism to prevent its operation by those not familiar with the combination of the permutation deyice.

In carrying out the present invention 1' provide a chain o't speed reduction gears adapted to be operated by the fiy-wheel of an internal combustion engine to advance a screw-threaded shaft carrying a revoluble member which rotates when the apparatus is in operation and is adapted to operate when advanced by the screw-threaded shaft to actuate an alarm mechanism and subse quently cut oil? the flow of gas to the engine, and also break the electric circuit to the spark plug; the above mechanism being incased in a housing and adapted to be shifted to its operative or inoperative position through permutation controlled device.

The invention is illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation of the case and its contents, with the cover of the case removed and parts broken away. Fig. 2 is a vertical section on the line 22 of Fig. 1, as seen in the direction indicated by the arrows. Fig. 3 is a horizontal section on the line of F 1 on a reduced scale.

Fig. 10 is a section and plan on the line 1010 of Fig. 1 on a redilccd scale. Fig. 11 is a detail inelevation on the line 11-11 of Fig. l'on a reduced scale. Fig. 12 is a perspective view illustrating the application of the invention.

More specifically, 15 indicates a metallic housing or casing which is box like in form and open on one of its sides to receive a sliding closure 16 the vertical edges of which are engaged iii-channels 17 formed on the inner faces of the side members of the housing 15; this closure 16 being designed to be locked in its closed position to prevent access to the interior of the housing, will be later described.

Mounted within the housing 15 and supported upon one 01" the side walls thereof is abracket 18, particularly shown in. Fig. 1, the lower end of which is secured to a stud 19 by a screw 20 and the upper end of which is secured to a stud 21 by a screw This bracket 18 is formed with a horizontal pen tion extending from the stud 21, a portion which extends downwardly at an inclination, its lower end being bent at a greater angle as indicated by 23 to form an inclined face for guiding the movement of aframe "24 supported thereon. This frame 2- has a l horizontally extending portion formed with an opening 26 through which the bracket 18 extends in slidable contact there with. The lower portion of the frame 24:

is also formed with a horizontally extending member 27 having an elongated, slot 28 therein through which the bracket 18 extends in slidable contact; the member 27 being normally arranged adjacent the upper end of the inclined portion 23 f the bracket, in which position it is sustained by means of a helical. spring 29 wound on the bracket 18 and bearing between a pin 30 on the latter andv the underside of the frame member 25. The opening 26 is of such dimensions as to permit a rocking movement of the frame 24 in relation to the bracket 18 to the limits permitted by the slot 28; the frame 24 being normally held with the inner end of the slot 5 28 abutting against the outer face of the bracket 18 by means of a spring 31 which is secured at one end to the lug 19 and at its opposite end to a depending hanger 32 formed on the horizontally extending mem- 20 her 2? of the frame 24. The frame 24 is thus spring supported on the bracket 18 and is adapted to be shifted longitudinally thereof and rocked in relation thereto, which movements will be effected, as later de- 25 scribed.

Formed on the member 27 of the frame 2 1 is a bearing in which a. short shaft 33 is revolubly mounted; this shaft having a friction .wheel 34; mounted on one end thereof,

the periphery of which wheel is adapted to be projected by rocking the frame 24 through an aperture in the side all of the case into frictional engagement with the periphery of the fly-wheel 36 of an internal combustion engine. The opposite end of the shaft 33 is provided with a pinion 37 which meshes with a toothed wheel 38 formed on a stud shaft 39 carried by a suitable bearing on the outer end of the member 27 of the 40 frame 24.; the pinion 40 affixed to the toothed wheel 38 meshing with a. toothed wheel. 41 on a stud shaft 12 journaled in the bearing on the upper member 25 of the frame 24.

The toothed wheel -11 carries a beveled pinion 43 on its rear face which pinion meshes with a corresponding beveled gear 44: having a, flanged hub 15 journalcd in a bearing formed on the frame member 25.

The beveled gear 44 has a threaded central opening 46 therein. adapted to receive a threaded shaft 47 held against rotation by means of a pin 48 thereon engaging a channel 49 on a rigid part of the frame 24 in such manner that when the beveled gean 4-1:

is rotated. the threaded shaft 47 will be advanced longitudinally therethrough.

Formed on the lower end of the shaft C7 is a. collar 50 which is slidably engaged by a sleeve 51 adapted to rotate in relation to the threaded shaft 47 and to which sleeve is .rigidly' secured a shaft '52 arranged in alinement with the shaft 17 and having its lower end guided in an opening 53 formed in a horizontally extending member 5st on the frame member 32. This shaft 52 is designed to be rotated independent of the threaded shaft 47 and irrespective of the longitudinal movement thereof. For this purpose a beveled pinion is mounted on the shaft and connected thereto by means of a screw 56 whichis threaded in the hub of the pinion 55 and extends into a longitudinal channel 57 formed in the shaft 52 in such manner that the shaft 52 may be re- 5 ciprocated longitudinally in relation to the pinion and revolved on the rotation of the latter. 1

The rotation of the pinion 55 is effected by means of a beveled gear 58 mounted on 30 the face of the toothed wheel 38. The lower end. of the shaft 52 is formed with a laterally projecting finger 59 which is adapted when the shaft 52 is lowered as later described, to intermittently strike a plate 60 35 adjustable vertically on a horizontally rockable sleeve 61 pivoted on a stud 62 and carryinga striker 63 normally held in contact with a gong 6ft. by a spring 65. The plate 60 is adjusted on the sleeve 61 by means of a thumb-screw 6-5 which passes through a vertically extending slot 66 in the plate 60 and engages a flange 67 on the sleeve 61. This adjustment of the plate 60 is provided for the purpose of disposing it'in different positions in relation to the lower end of the shaft 52 so that it may be adjusted to be struck by the finger 59 to actuate the striker 68 to sound the gong 64 at various predeterminedpoints in the downward movement of the shaft 52.

Interposed in the path of downward travel of the shaft 52 is the arm 68 of a bell crank lever mounted on the stem 69 of a normally open cut-off valve 70; the other arm 71 of the bell crank lever extending upwardly and connected by a link 72 at its upper end to the lower end of a knife switch 73 pivoted at 7 1 on the side wall of the case The valve 70 is disposed within the case 15 and connects at one side with a pipe 75 leading from a source of gas or hydrocarbon supply, as a'tank 76, and connects on its opposite side with a pipe 77 leading to the carburetor 78 of the engine 79 for driving the vehicle indicated at 80.

The arm 68 of the bell crank lever has its outer end adjustable by means of a set-screw 81 by which the point of its engagement by the shaft 52 may be varied as occasion requires; this bell crank lever being designed to be operated by the downward movement of the shaft 52 to close the valve 70 and thereby cut ofl the flow of fuel to the carburetor 78 and engine 79 and simultaneously move the knife-switch 73 out of engagement with a contact 82, and thereby break an electric circuit through conductors 83 leading from one/side of the magneto coil 84 of the contact 82, and a conductor 85 lead- 30 of reciprocal :1 be reciprocated 'lUllglttl the horizontal portion of the bracket 18 with.

its peripheral edge normally bearing against a friction roller 89 mounted on the upper edge of the frame member 2 1, as part1cnlarly shown in Fig. a. This cam disk 88is normally locked against movement and is unlocked and operated by a permutation device to prevent unauthorized persons from manipulating the same to throw the alarm mechanism in or out or operation.

The cam disk locking means isparticularly shown in Fig. 3, and comprises a series o s, here shown as in number, and des These rods exter upper-end of ends projecting finger engaging iorizontally adjacent the case 15 with their outer through and titted with by which they may oinally in an outward direction in opposition to s rings 95 bearing between pins 96 on the rods, and a dependent hanger 97 carried. by the top plate of the case 15. The inner ends of any one or more of the rods normally project into sockets formed in the face of the cam disk 88; in this case the rods 00 and 91being shown as normally engaging sockets 98 and 99, thus holding the cam disk against movement.

The inner ends of the rods 92 and 93 are connected to levers 100 as shown in Fig. 1, whichin turn are connected to short bars 101 and 102 normally positioned out of contact with sockets 103 and 104C in. the cam disk 88. The cam disk and the locking rods are concealed within the case so that it is necessary for the operator to know which one of the rods 90, 91, 92 and 93, singly or collectively, must be pulled in order to release the cam disk. In this illustration the rods 90 and 91 comprise the locking rods and the rods 92 and 93 are the guards; these guard rods operating when pulled, to advance the bars 101 and 102 into the sockets 103 and 104 in the cam disk so as to lock the latter against movement, from which it will be seen that if the rods 90, 91 and 92 are pulled downwardly. while the cam disk is released by the withdrawal of the rods 90 and 91, it will be locked by the introduction of the rod 101 to the socket 103.

It is manifest that the number and arrangement of these rods may be carried out ated 8.390, 91, 92 and 10%. This hand hold is provided with a shank 105 adapted to extend through a slot 106 in the top of the case 15 and also through an aperture 107 in' a peripheral flange 108 formed on the cam disk 88 with the lower end of 'the shank 105 terminating adjacent the face of the portion of the bracket 18 in which the cam disk is pivoted.

The lower end of the stern 105 is formed with a cutaway portion 109, which, when the hand hold 104; and stem 105 thereon are turned to a predetermined position, will perrnit the stem to pass an abutment 110 mounted on the bracket 18 adjacent the cam disk 88, as illustrated in Fig;- 5, and which abutment operates to engage the stem 105 to prevent rocking of the disk 88 when the stem 105 is not turned to its proper. position.

To determine the necessary position of the stem 105 in order that the cut-away portion 109 will clear the abutment 110, a dial 111 is formed on the hand hold 10% and formed with numbered radial lines, one of which extends directly at right angles to the wall of the cut-away portion 109. In the illustration of this device in Fig. 6, this line is numbered 6, and when this line is positioned to extend in alinement with an arrow or other mark 112 formed at the outer edge of the slot 106, the cut-away portion will be positioned as shown in Fig. 5 so that the stem 105 will pass the abutment 110. The hand hold 104: is held against displacement by means of a cotter-pin 118 which is passed through the stem 105 adjacent the underside of the flange 108, as shown in Fig. 4.

1n the application of the invention the case 15 is rigidly attached to the frame of the vehicle in such manner as to prevent its being easily removed and is arranged with the opening 35 adj agent the periphery of the fly-wheel '36; flanges 114 on the case 15 on the marginal edges of the slot 35 projecting in close proximity to the periphery of the fly-wheel to prevent the introduction of implements for the purpose of interfering with the operation of the device.

Ordinarily the parts are disposed as shown in full lines in F ig. 1, that is, with the frame 24 in its uppermost position and friction disk 34 out of contact with the fly wheel 36. The threaded shaft 47 will also be in its uppermostposition and the bell crank lever on the valve stem 69 will be disposed in its uppermost position by the action of a spring 115. When the parts are thus disposed the circuit from the magneto coil 84: to the spark plugs 90 is closed and the valve 70 is open to permit the passage of the hydrocarbon mixture from the tank to the carburetor 78.

The engine 7 9 can be set in operation without aii'ecting the alarm device.

When it is desired to set the alarm device to prevent theft of the vehicle the operator manipulates the'hand hold 104 and the cam disk locking bars according to their combination so as to release the cam disk and position the hand hold so that it may be moved to rotate the cam disk and thereby cause'the latter to bear downward on the upper portion of the frame 24 to shift the latter in opposition to the spring 29. The downward movement of the frame 24 causes the end of the slot 28 to ride over the underside portion its enlarged portion against the frame 24, in

which position it is locked by the engagement of one of the locking bars with asocket 116 with sockets 1.17 and 11S positioned opposite the locking bars 101 and 102. When thus positioned the hand hold 104 will be turned so as to move the cut-away portion 106 out of alinement with the abutment 110 so that in event the locking bars are successfully disengaged from the cam disk the latter cannot be readily operated. However, the apparatusis designed to be concealed within the vehicle as much as possible and the gripping rings 94 of the locking barsare hidden beneath an overhanging shelf 119 so as not to be apparent to the ordinary observer.

The operation of the invention will now be as follows: Assuming that the engine 79 is set in operation by an unauthorized person with the-intent of wrongfully using or operating the vehicle and that the device is adjusted as just described. The rotation of the fly-wheel 36 will act to revolve the friction wheel 34 which in turn will operate through the pinion 37, toothed wheel 38, pinion 40, toothed wheel. 41 and pinion 43 to rotate the beveled gear 44 and the pinion 55, this latter being rotated by the revolving of the beveled gear 58 on the toothed wheel 38. The rotation of the beveled gear 44 will operate to advance the threaded shaft 47 in a downward direction, thus advancing the v shaft 52, which will be rotated by the action of the pinion 55. The downward movement of the threaded shaft 47 is designed to be slow so as to permit the person driving the vehicle to travel a predetermined distance before the lower end of the shaft 52 will be advanced sufliciently far for the finger 59 to strike the plate 60. The unauthorized driver of the vehiele can thus travel a distance Without being made aware of the presence of the alarm mechanism, which has been previously set by adjusting the plate 60 to operate at a predetermined distance of travel of the vehicle, which point is governed by the distance of the plate 60 from the lower endof the shaft 52. By this arrangement the alarm will be sounded when the vehicle is in motion and while occupied by the unauthorized person, thereby reasonably assuring the ascertainment and capture of such person, which ordinarily would not be possible were the alarm set offaat the time of starting the engine. When the shaft 52 has been advanced downward a sufficient distance the finger 59 will strike the plate 60, thereby rocking the sleeve 61 in opposition to the spring 65 and causing the tapp er 63 to rapidly strike the gong 64 to sound the alarm. Immediately thereafter the shaft 52 will move into engagement with the arm 68 of open the slide closure 16, which is normally locked by means of one of a pair of reciprocal bolts 127 and 128 mounted in a guide 120 on the floor of the case 15; the bolts 127 and 128 being connected to the opposite ends of a short lever 121 pivoted at 122 and positioned by means of a spring 123 on the bolt 127 in such manner that one of the bolts will be normally disposed in an advanced position and the other in a retracted position. Connecting with the lever 121 is a cord 124, which passes around a direction roller 125 and is connected at its upper end to the lower member 27 of the frame 24 in such manner that when the frame 24 is in its lowermost position to relax the cord 124 the spring 123 will maintain thebolt 127 in its advanced position in engagement with a lug 126 on the underside of the closure 16 and when the frame 24 is in its uppermost position the bolt 127 will be retracted in opposition to the spring 128 and out of engagement with the lug 126 and the bolt 128 will be advanced into engagement with the lug 126 by reason of the lever 121. It'thus becomes necessary to dispose the frame 24 inan in:

tel-mediate position in order to arrange the bolts 127 and 128 both out of connection with the lug 126. This can only be effected the bolts 127 and 128 in relation to each ner s other. different positions of the cam disk Will accordingly be necessary to position the bolts 127 and 128 clear of the lug 126. if desired, the lever 68 can be adjusted by means of the set screw 81 to operate in advance of thelever so as to stop the vehicle without sounding an alarm, or it may be adjusted, to operate at any desired time in relation to the sounding of the alarm.

By the use of this invention the proprietor of a power propelled vehicle can leave the vehicle unguarded with the assurance that in event it is maliciously taken that an alarm Will be sounded and the vehicle automatically stopped Within certain limits and by reason of the combination locking mech anism controlling the alarm mechanism the proprietor of the vehicle will have a secret combination lock for guarc ling the vehicle against. theft or improper usage.
