My present invention relates to automotive devices and more particularly to an improved anti-theft-device for automobiles and the like.
It is important to prevent theft of automo biles and like pieces ofapp aratus and also it is important to prevent unauthorized use of such devices. 1T0 this end, numerous appliances have been devised for rendering it inipossible for a person other than the owner or an authorized party to be able to operate the automobilei Such appliances have taken various foriiis, such as steering wheel locks,-
transmission locks, door locks, ignition locks,
fuel feed locks and the like, and many of.
these devices have been unsuccessful. in my present invention, 1 have obviated objections to prior apparatus of this character and have associated with and forming anintegral part of the carburetor itself, a valve controlled by a permutation lock and, therefore, nothing short of substitution of a new carburetor for the one employed, will permit the unauthorized useor appropriation of th car. Such substitution, however, takes considerable tim and more time than it is possible for a would-be thief to devote to the work iIrOIClQI to escape detectionfi In carryingout my invention, Iform in the body of the carburetor, a valve seat connected to the intake pipe from thefuel tank and'connected also to the entrance pipe from the carburetor proper, and associated with such valve seat I provide a rotatable valve plug comprising a plurality of parts relatively movable with respect to each other, such movable parts of the plug having passages therein adapted to register with the inlet and outlet pipes and which can only be brought into registry with such inlet and outlet pipes by the'proper manipulation of a permutation lock device attached to the valve stem or plug and located without the carburetor body. As the permutation lock is capable of being setin a multitude:ofseparate and distinct 'thefeed pipe, it is impossible to theinstrument board.
from operating the loclr'and, therefore, prevente d from' operatingthe machine. Being in the body of the carburetor, which is essential to the operation of the car and notfiii Another object of my invention is an improved anti-theft device for automotive vehicles associated with the carburetorthereon.
.' Other objects andiiovel featuresofthe construction and arrangement of parts compris v ing the device will appearfas the description of the invention progresses. I l I the accompanying drawings, r Fig; 1 is a front elevation ofa carburetor to which my i iventi onhas been applied V Fig. 2 is an end elevation of the carburetor shown inFig.1;-

The float chain'- ber 10 and flange 11 are both secured to the body 11 of the carburetor and formed integral with the body 11 is a member 15. Formed in the member 15 is a vertical pas.- sage 16 communicating by a passage 17 with the annular chamber 18 formed in the body 14; The lower end of the passage 16 is internally threaded to receive a threaded plug 19; 'At right angles to the passage 16 and in the member 15 is a tapered valve seat 20 and communicating with the valve seat20' is a passage 21 leading from the interior of the float chamber 10,-this passage 21 having a valve stem 22 associated therewith and conplace abyis trolled in the usual manner by the float (not shown) ordinarily located in the float chamber 10. Also communicating with the valve seat and located at substantially right angles to the passage 21, is a passage 23, this passage teri inating in the valve seat 24 that has associated therewith a valve 25 operated by a handle 26. Communicating with the valve seat 24 and, therefore, with the passage 23 is a passage 27 leading from the vertically arranged passage 16. The passage of fuel from the "usual source of fuel supply is through a pipe 28 through a valve (not shown) controlled by the usual float, into the float chamber 10 through the passage 21, the tapered valve seat 20, passage 23, passage 27, passage 16, passage 17 and into the annular chamber 18 and thence into the engine cylinders.
Rotatably mounted in the valve seat 20 is a compound valve comprising members 29' and 30, respectively, turned to it the taper of the valve seat 20, and when in position, being slightly separated from each other, as clearly shown in Fig. 4. The member 29 is provided adjacent its larger end with a longitudinal passage 31 which is adapted to be brought into or out of registry with the passage 23 and also this member 29 is provided on its larger end with a projection or lug 32. Also, the member 29 is provided with a recess 33 arranged,longitudinally thereof in which fits a spring positioning plug 34 and 'a coil spring 35. The member is provlded at its smallerend with a longitudinal groove or passage 36, which is adapted to be brought" with a lug or projection 38 adapted to engage with the lug or projection 32 .on the member 29' and forms'means for rotating such member 29. The larger end of the member 30 is recessed to receive an enlarged end- 39 of a shaft 40, such enlarged end beingprovided with a radially extending projection 41 engaging with a recess 42 in the member 30 and which will allow the member 30 to be rotated by the shaft 40. The outer end of the tapered valve seat 20 in. the member 15 is recessed to receive the reduced end of a gland a3, a screw 4.4 passing through the walls of the member 15 and engaging such gland 43 to prevent the accidental withdrawal thereof. The gland 43 is drilled to 7 receive the shaft with a sliding and rotating fit and between the inner end of the gland 43 and the outer end of the tapered plug member 30 is placeda spring centering dcvice 45, this spring centering device being located within the open end' of a coil spring 46, the other end of this spring surrounding the outer end of the plug member 30. The
the periphery of the member 51 aredepressions 53 fora-our Jose to be hereinafter described. The member 49 is provided with a right-angled extension 54, adapted to be engaged by a screw 55. This screw 55 is adapt-- ed to be positioned in any one of a plurality of threaded holes 56 circumferentially arranged on a circular plate-57 that is rotatably mounted on the member 51. The mem her 57 is provided with a radially extending iassage enlarged at its outer end and in such passage is slidably mounted a pin 58, this pin sing yieldingly urged inwardly by a spring '59 held in the aforesaid radial passage and by a screw 60. Theconstruction above described renders it possible for a member 57 to be rotatably mounted on the member 51 and yieldingly held in adjusted position thereon by engagement of the pin 58 with any one of the depressions 53. The face of the disc 57 remote from the member 50 is provided with graduations,as clearly shown in Fig. 1. On the shaft l0 adjacent the outer face ofthe disc 57 is a cylindrical member 61 held to the shaft 40 by a pin 62 and longitudinally extending from such cylindrical member 61 is a .pin 63. The pin 63 is adapted to engage in any one of a plurality of circumferentially arranged recesses 6d drilled in a dial member 65 and at the bottom of arecess 66 therein. diameter and depth to house-completely the c *lindrical member 61, as clearly shown in Fig. 4. The dial member 65 is'bevelled, as
shown in the drawings, and the bevelled face is provided with a plurality of graduations. Also the member 65 is provided with a knurled extension 67 and by. means of which such member 65 may be readily turned. The member 65 is provided with a central longitudinal perforation through which extends the shaft 40 and the outer end of the knurled portion 67 is recessed to receive a member 68,.such member being secured to the member 67 by screws 69. The inner end of the member 68 is threaded to receive the outer threaded end of the shaft 40. The apparatus, being constructed and assembled as above described, it will be obvious from an inspection of the drawings that because of the limited independent movement of the plug members 29 and 30, the grooves 31 and 36 in such members respectively may be brought This recess-is of sufficient into registry with the passages 23 and 21-re- 'spectively and also that such grooves 31 and 36 may be moved out of registry With their respectively associated passages. Also it is evident that the shaft 40 maybe turned to accomplish this result andthat' such result will only-be accomplished if the person operating the same is able to determine the amount of rotated movement to impart to the shaft 40 and the particular direction or directions in which the shaft 40 must be rotated. It is obvious also that rotation of the shaft 40 in one direction only will bring first groove 31 and then groove 36 successively into registry with their. re spectively associated passages but rotation in one direction will never result in having such passages both simultaneously in registry with such respective passages and therefore it will be necessary to first position the passage 31 in registry with its associated passage 23 and then, by reversing the direction of rotationof the shaft- 40, brin ing the groove 36 into registry with the passage 21, the disc 57 may be rotated on themember 51 until the screw engages with one side or the other of the angular extension 54 of the member 49 and the position in which such disc 57 will be brought to rest with respect to such extension 54 may be varied by varying the position of the screw 55 by means of the threaded holes 56. Therefore, the disc 57 which, with the graduations on the outer face thereof, forms practically a movable zero indicator, may be given a plurality of independent positions and the particular position in which, the
7 same is to be set can be known only to that varied accordingly. Only the person who makes the setting, therefore, or the authorized operator will be aware of the proper position of the dial member and disc 57, which will bring the groove 31 in the plug member 29 into registry with its associated passage 23 and the same is true also with regard to the setting of the groove 36 in registry with its passage 21. My device is, there fore a device which absolutely prevents any but an authorized person from connecting the source offuel supply with the carburetor in such a manner as to allow a constant flow 'of fuel from one to the other.
Referring now to Fig. 6, there is shown the carburetor 10, having my device in the extension or addition 15 thereof, and the equivalentof the shaft 40 is designated by the numeral 75. This shaft may be of any I suitable length and is provided at its end with a universal joint'76, to which is also attached a shaft 77. The upper end of this shaft is equipped with a universal joint 78,
to which is also attacheda shaft 79, which" 7 extends through the instrument board of an automobile or other like device and the endof the shaft'79 is identical in structure with the outer end of the shaft 40 above described and as illustrated in Fig. 4. To
therefore, the valve mechanism heretofore; described and as illustrated in F1gs.'1 to 5,
may be readily operated and controlled from the drivers seat. I
It is to be understood therefore, that While,
,in the main, my description relates to'the valvemechanism associated with the carburetor and controlled by a device directly mountmote control such as that just described and illustrated in Fig. 6 may be employed and is within the scope of my invention.
Having thus described my invention, what Iclaim asnew is z p An improved anti-theft'device for liquid ed on the valve stem, yet any means for re- 7 or gaseous fueland the like comprising, a
member, a valve seat formed in said mem-' her and said member being provided with passages extending to a feed supply and to a fuel supply, a two-part valve rotatably mounted in the valve seat, said parts being in axial alinement with each other and yieldingly spaced apart from each other, said valve.
parts being provided with grooves co -operating each with a respective-passage in the member, and the space between the valve parts forming a conduit to connect said grooves, an operating valve stem connected to one of said valve parts, interacting means on the adjacent facesof the valve members and by means of which one of the valve parts is controlled by the other and a permutation device secured to the axially extending stem and by means of which the valve parts are operated to bring the grooves therein'into or out of alinement with the associated passages in the member.
In testimony whereof, I have signed my name to this specification.
