CARBURETER-LOOK.
To all whom it may concern:
Be it known that I, CHARLES EDGAR Non'rHRor, a citizen of the United States, and a resident of Dayton, in the county of Montgomery and State of Ohio, have invented a new and Improved Carbureter Look, of which the following is a full, clear, and exact description.
The invention relates to carbureters of internal combustion engines such as are used on automobiles and other vehicles.
The object of the invention is to provide a new and improved look more especially designed to cut off the supply of gasolene or other liquid fuel from the needle valve thereby preventing running of the engine by unauthorized persons.
Another object is to permit of conveniently applying the lock to carbureters as now generally constructed.
With these and other objects in view, the invention consists of certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of the improved locking device as applied to a carbureter, the reservoir and front of which are shown in section;
Fig. 2 is a front elevation of the same with parts in section;
Fig. 3 is an enlarged cross section of the same on the lines 3-3 of Figs. 2 and 4;
Fig. 4 is an enlarged sectional plan view of the same on the line 4.4 of Fig. 2;
Fig. 5 is a similar view of the same with the parts in a different position;
Fig. 6 is a similar view of the same with the parts in still another position;
' Fig. 7 is a cross section of the same on the line 7--7 of Fig. 5; and
Fig. 8 is a cross section of the closing valve in open position on the valve seat tube of the needle valve controlling the flow of the liquid fuel from the reservoir of the carbureter to the mixing tube leading to the inlet manifold, the section being on the line 8-8 of Fig. 2.
The carbureter on which the improved lock is ap lied is of usual construction and is provied with a reservoir 10 containing a Specification of Letters Patent.
Patented July 12, 1921.
Application filed September 19, 1919. Serial No. 324.968.
The valve seat 18 of the seat tube 17 is adapted to be closed by a lock-controlled shut-off valve 20 to prevent the flow of gasolene or other liquid fuel from the reservoir 10 to the mixing tube 13 even should the needle valve 15 be in open position. The shut-01f valve 20 is mounted to slide in an extension 21 of the tube 17 and this valve is pressed on by a spring 22 to normally hold the shut-off valve 20 in open position. The stem 23 of the valve 20 is engaged by one end of a lever 25 fulcrumed at 26 on one side of the tube 13 and this lever is pivotally connected with an arm 27 of a bolt 28 slidingly engaging the inner end of a key tube 30 mounted to turn in a suitable bearing 31 arranged on the under side of the top 32 of the reservoir 10, as plainly shown in Figs. 3 and 7 The key tube 30 extends through the top 32 into a boss 33 formed on the top 32 and normally closed by a suitable cap 34, as shown in Figs. 1 and 2. A key 40 is adapted to be inserted .in the key tube 30 at the time the cap 34 is removed from the boss 33, and this key 40 is provided with a slot 41 in which is mounted to swing an arc-shaped tumbler 42 pivoted at 43 on the key 40 within the slot 41, as plainly shown in Figs. 3 and 7. The key tube 30 is provided at its upper end on one side with a slot 44 to accommodate the tumbler 42 when inserting the key 40, and the bottom of this slot provides a cam 45 for im parting a swinging motion to the tumbler 42 to project the latter through a slot 46 formed in the opposite side of the key tube 30. The top 32 is provided with a groove 47 adapted to register with the slot 44 to allow of inserting the key with the back of the tumbler 42 passing down the registering slots 44 17.2 Prior to :the' lowerz'endof the key reaching; the :top' 'of the bolt. 28, theitumbler 42 engages the earn 15 and is thusswung through the "slot .46 into engagement with the slot:50:inthe-tumblerplate-51. The ep- The free end of the tumbler 12 is adapted to pass into a slot 50 formed radially in a tumbler plate 51 having ahub '52 mounted to turn loosely on the key tube 30. -A spring pawl is attached to the under sideot the top 32 and normally projects into the slot 50 to hold the tumbler plate 51 against accidental turning but to allow the tumbler 4:2 to
turn the plate on inserting the key 40 into the tube 3.0. Aasecontl tumbler 'plate 'mounted to turn loosely" on thehkey tube "30 and thistumblerplate "60 isprovidedwith pawl outward into the; position shown-in Fig. 5, and the other lug G'Tis adapte'dto engage a notch-6S formed inthe peripheral itace :of \the plate- 60 :to hold the latter in looking position, as. indicated in'Fig; 6; The
tumbler plate GOb-is adapted topas's'over the topo'f an arm forming anlente-nsion or the bolt 28 11nd slidingly engaging a tube 1 attached to the bearings '31. The tumbler plate 60 engages the top of: the arml70'at the time theval-veQJO is pushed into closed :position tozhold the'valve 20loeked inithe closed position on the V operator withdrawing the -=key 40 from the'tube30. wThe operation isas follows:
-Normally'the valve- 20xis'in open o'osition :withithetumblerplates 51va nd 60 in'the position -sh'own i in 'Figs. 3 and '4, l that is, twith the slot 50 of the plate 51in diametrical alinement with. the registering slot-s 44%and-1 17. When the; operator ot'an automobile or other vehicle desires 1 to close the :seat tube 17 by the val've 20 then'the operator fir-stremoves the 'cap 34, th'enrarinserts'the keyAO into the key tube "30 withjthe tumbler 4'2 sliding vdown in the registering slots' lct and 40 orator new tunes theikey' 40 thereby-turning the tumbler: plate 51rto thei, position shown in Fig. 5, t-h-atis, until the sl0t50 registers with the slot-61. The key 410 is now pressed 'fur- :theri downward :in vthe tube 30 "to cause the bolt 28 to move downward-sand impart a swinging '1' mot-ion to the lever '25 which, acts .iiig .against the stem 23. of the \valve 20, moves the latter into; closed position-"on the seat .18 of the -tube 1'7. The operator n'o'w gives a further turn to the key 40 whereby the tumbler plates 51 and 60 are swung into the position 'shownin Figs. 5 and 7 thus moving the tumbler plate 60 over the top of the branch arm 70 moved downward with the bolt 28 below the under side ofthe tumbler plate 60. lVhen the tumbler plate (50 reaches this final position the lug 67 of the pawl 65 engages the notch 68 in the tumbler plate 60 thuslocking the latter against return movement. T he operator now slightly withdraws the key to disengage the tumbler 12 frorn the slot 61 b 1'1t to remain in'theslot 50 thus allowing of glvinga:return turning movement to i the key to turn the tumbler plate '51 back into its normalposition, shown in Figs. 3, 4 and 6, that is, with the slot50 diametrically o'pposite the registering slots i l -and 4:7; Thekeysi'dcan now be withdrawn from the tube "30 but as the-tumbler plate 60 extends over-the branch nrm- '70 of the bolt'QS'the latter is held against-return movement and consequently the yalve 2O .is held 4 in closed position I on' its *valveseat 18.
By this arrangement 'gasolene or other liquid fuel cannot now flow fro'mith'e'{reservoir 10 into the m1x1-ngtube13 and consequently the formation "of ":an explosive "mixture is .pre-
vented and the engine cannot'be:runeven should the needle va'lve15 be opened. When it isclesire'd to allow the valve-20 to move into open position by the. action ofitsspring 22 then the operator .reinserts the 4 key '40 in the tube 30 whereby the tumbler 142 reengages the slot 50 I to allow 1 of turning the tumbler plate 51 back until the slot-50 (registers with the slot '61; On I pushing the key ClOWINVLLTCli the tumbler 4:2 engages the lug "66 thus swinging-the pawl 65loutwa'rd to disengage the" lug: 67 from the much i 68 thus unloc-lring the tumbler [plate 60. @n"now turning the hey 410 in reverse direction, the tumbler plates 51 and 60 are turnedsimultaneeusly in a reverse direction untilthe' tumbler plate'60 clears the'ib ranchipin 70 anch the tumbler engages: the lug 66'whereby the latten is pushed down-ward out ofen'gageanent with the islet 61. 11 further turning of the key imparts a furtherturningnrove- 'mentto the tumblen plate 51 tomove the slot 50 out of register..with theflslot 51an d into diametricals'alinenrrent with the slots 4:4: and 4:7 to permit of =-\vith'drawing. -tlre ltey g'from the: tube '30. :It isiuuderstooch that when the tumbler plate 60 moves out 201* ffengagemeiit with the-'arm -7O; thevalve 20 can move to its "seat :18 l the withdrawal of: thezikeyAO from thetube 30.- i 1 vSome of the features of the lock aresiinh laruto corresponding iones in :the lock-shown and described in the Letters :Ba'te'nt ofthe" United States, No. 1,274,313, granted zto me July-30,1918. r
