. In Switzerland November 30, 1948 '1' Claim. (arm-2) vThe object of the present invention is a fuelissuing slot or prepayment machine which may be used, for instance, for filling cigarette, cigar or pipe-lighters with fuel. d
The coil-operated fuel-issuing machine in accordance with the invention is designed on the principle whereby a fuel reservoir communicates with a cylinder and the latter communicates via a pipeline, with a delivery nozzle, a piston controlled by a coin-operated mechanism being movably arranged in said cylinder and impellin an accurately metered quantity of fuel to the delivery nozzle. I
The enclosed drawing illustrates a typical embodiment of the invention, in which drawing;
Fig. 1 is a vertical section, whilst Figs. 2 to 4 are details of the coin-operated mechanism. 7 I
The coin-operated fuel-issuing machine shown comprises a cabinet I closed at the top by a lid 2. In the cabinet I is accommodated a fuel tank or reservoir 3 which is in turn closed at, thetop by a lid 4. A cylinder 5 is mounted in thebottom of the tank 3, a pipe-line 6 being connected to said cylinder 5 and leading via a valve unit 1 anda ball-retaining valve 8to thedeliverynozzle 9. This nozzle is of such design (not shown in the drawing) that its outlet aperture opens automatically when a container to be filled is pressed up against said nozzle, whilst it also closes automatically when said container to be filled is removed from said nozzle. A pump-piston l mounted in the piston guide II and arranged on a piston-rod l2 co-operates with said cylinder 5. Said piston-rod passes through the lid 4 and is subject to the action of a spring l3 which bears at one end against a washer I4 which in turn bears on the lid 4-, and at its other, lower end against a transverse cotter l5 in the pistonrod l2. The spring [3 tends to force the pistonrod l2 downwards, and thus to force the piston I0 into the cylinder 5. At its upper extremity the piston-rod 12 carries by means of a screwthread I6 a forked element H the top of which is pierced by a spindle [8 on which a roller I9 is sov mounted as to be loosely rotatable. One arm 20 of a bell crank 2| projects into said forked element H, the other arm 22 of said bell crank bearing on a roller 36 of the coin-operated mechanism.
Said coin-operated mechanism is shown in detail, in various positions, in Figs. 2 to 4. As can be seen from Fig. 1, the coin-operated machine is provided with a chute 24 which leads downwards and to the rear the coin inserted through the slot in the front wall of the machine. Be-
' slot 26.
low the aperture of the chute 24 a slot 26 is provided in a slide 25, so that any coin inserted into the slot of the machine and dropping rearwards down to the chute 24 is able to enter said It is prevented from falling through said slot 26 by a pin 21 mounted in a position transversal to the longitudinal axis of said slide and slidable in the latter. A leaf spring 28 which embraces the head of said pin 21 tends to maintain said pin in the position shown in Fig. 3. As this figure shows, said pin 21 is provided with a recess of slot 29 the breadth of which corresponds to the breadth of the slot 26. A spring 3| is secured to a pin 30 in the slide 25, the other end of said spring being fastened to a pin 32. Said spring 3| tendsto draw the slide 25 in an outward direction, i..e., to the left in Figs. 2-4. At its extreme end the slide 25 carries a screw pin-33 on which the pressure or ripping unit 34 is fitted. By means of the latter the slide 25 can be moved against the resistance of the spring 3|. In the slide 25 a roller 36 is mounted on a spindle 35. Said roller 36 is so mounted on-the spindle as to be slidable in an axial directiQn, anda spring 3! tendsto press saidrolleragainst a wall 38. In this wall is provided a slot 39 the shape of which is illustrated in particular by Figs. 1 and 2. This slot has a circular extension 40 through which the annular flange 4| of the roller 36 can pass. A second, corresponding extension 42 (Fig. 1) is located in the slot 39. Behind the wall 38 a leaf-spring 54 is secured by means of a rivet 43, the shape of which is seen in Figs. 3 and 4.
The coin-operated machine functions in the manner described hereunder:
Assuming that the fuel tank 3 is completely or at least partly filled with fuel; if a coin is inserted into the chute 24, it falls on to the slot 26. If the coin inserted is too small, it automatically falls right through. If however, the coin is of the correct size required, it comes to rest on the pin 21. If the stud or button 34 is now pressed, thus sliding the slide 25, the head 44 is forced up against the guide surface 45 of the coin-insertion device. As is shown in Figs. 3 and 4, said guide surface 45 is so designed that it displaces the head 44, and with it the pin 21, in a transverse direction to the direction of movement of the slide 25, said displacement being all the greater the further said slide is moved to the right. At a given moment, the slot or recess 28 will coincide with the slot 26, the coin then dropping into a, cashbox not shown in the drawing. Whilst the coin, designated by the numeral 46 in Fig. 2, was bearing on the pin 21, it was brought, by the rearward motion of the slide 25, up against the retaining hook 41. The fore end 48, of hooked shape, of said retaining hook rests, when the mechanism is at rest, in a recess 49 in the slide 25. The rear end of the retaining hook 4'! is subject tothe, action of a, spring 50 the upper endof wm ugbegrs a 'infstjthe hjolthad 5!. When the slide 25 containing the coin '46 is pushed back, said coin pivots the fore end 48 or the hook 4! in a clockwise result that said fore end 481's witli'dfaZwhTf-i'bhi the slide 25, i. e., from the recess 49, when tinuance of the inward movementoftthejsliueifipossible.
