XVILLIAM HENRY FAHRNEfY, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 563,464, dated July *7, 1896.
Application filed March 11, 1895.
To all whom it mag concern.-
Be it known that I, WILLIAM HENRY FAHR- NEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottle-Fillers, of which the following is a full, clear, and exact specification. 1
My invention relates to means for holding open the valve between the bottle and the supply until the level of the liquid in the bottle has reached a predetermined point, and then closing such valve or permitting it to close. It has heretofore been proposed to effect this operation by means of a float so arranged that the liquid upon rising to a certain level would raise the float against two contacts and thus close the circuit through the float and shut off the supply; but in practice it is found that this prior method is ineffectual, because, owing to the necessarily small dimensions of the float, its buoyancy is too slight to produce sufficient'pressure on the contacts (which are often coated with the dried substance of which the bottle is filled) to complete the circuit. Then, again, in the majority of instances, the liquid is more or: less-adhesive, which property in some cases causes the float to stick, while it invariably renders the movement of the float so slow that the bottle becomes too full'before the float reaches the contacts. p
The invention has forits primary object to cause the liquid in the bottle to constitute the conductor for automatically effecting the closing of the Valve the instant the level of the liquid in the bottle reaches a certain point, thus insuring absolute accuracy and uniformity of measurement in filling, and consequently avoiding a great source of an noyance heretofore caused in bottle-fillers lacking these advantages.
Afurther object of my invention is to cause the valve to automatically open when the bottle is placed in position for, filling.
' My invention consists, primarily,in regulating the discharge into the bottle by means'of jects and certain other objectshereinaftera'ppearing my-invention consists, further, in
seal No. 541,228. (No as.)
certain features of novelty hereinafter described,'and particularly pointed out in the claims, reference being had to the accompanyin g drawings, showing anexample of my improved apparatus for carrying out my improved method.
In the said drawings, Figure 1 is a diagrammatic view of the improved apparatus, showing the valve open and the bottle filling. Fig. 2 is a similar view-of the same, showing the valve closed and the bottle filled. Fig. 3 is a side elevation of the apparatus, showing its construction morecin detail, the bottle being omitted; and Fig. 4 is a detail plan section taken on the line 4 4, Fig. 3.
'Like signs of reference indicate like parts throughout the several views.
In' adapting my improvements and method for use in connection with a bottle-filler having a valve which controls the discharge from the supply into the bottle, I hold the valve open by means of electromagnetism, and cause'such valve to close by gravity or other means when the current producing such electromagnetism is broken by a second current closed through the liquid in the bottle when such" liquid reaches a predetermined point. I find it more convenient, practical, and preferable to hold the valve open by the magnetic influence and to permit it to close by gravity, assisted, if desired, by a spring or other means, instead of holding it closed by the magnetic influence and forcing it open by a spring or equivalent device; but it will nevertheless be understood that this latter arrangement is but an obvious reversal of.
that which I have described and shown as the preferred way. i
. Referring now more particularly to Figs. 1 ahd'2 of the'drawings, 1 represents the tank or supply, from which'e'xtends a pipe 2, leading to a valve-chamber 3,having a valveseat 4, from which depends the bottle-pipe 5, through which the liquid discharges into the bottle 6. Within the valve-chamber 3 is located a valve 7, whose stem 8 passes upward through a plug 9 in the upper side of the valve-chamber and has sleeved upon it a coil-spring 10 for assisting gravity and the weight of the liquid in the chamber toquickly and firmly seat the valve. The upper or outer end of the stem 8 is provided with an armature 11, over which is supported an electromagnet 12, which, when energized, raises the armature and consequently holds the valve 7 from its seat against the influence of the spring 10. The electromagnet 12 is in circuit with a source 13 of electricity through the medium of the conductor 1%, the isolated contact 15, the switch 16, the arm 17 of the frame, the conductor 13 in electrical connection with such arm 1.7 and with one pole of the source 13, while the other pole of such source 13 connects with the other end of the helix of magnet 12 through-the medium of the conductor 19, the switch 20, and conductor 21. Thus it will be seen that so long as the described circuit is complete the magnet 12 will attract the armature 11 and hold the valve open, but as soon as the bottle is removed from its support 22, situated on the spring-switch 16, the latter will rise out of connection with the contact 15 and break the described circuit, thereby permitting the valve to close instantly and prevent further escape of the liquid. In order, now, that the described circuit may also be broken when the liquid in the bottle reaches a predetermined level, the bottle-pipe 5 is provided with an isolated contact 23, which, like the bottle-pipe 5, projects downwardly into the bottle, but preferably terminates a considerable distance above the lower end of the pipe 5. This isolated contact 23 is connected by ccnductor 24 to one end of the helix of an electromagnet 25,, while the other end of such helix is in electrical communication with the source of electricity 13, via conductor 26, the pipe 5 being metal or provided with an electrical connection extending from its lower end to the metal fittings or castings to which it is connected, or any other electrical communication may be established between the lower end of the pipe 5 and the pole 18 of the battery 13.
The magnet 25 is arranged opposite an ar1nature 27 on the switch 20, so that the instant the magnet 25 is energized the armature 27 will be attracted and the circuit through the magnet 12 broken, Hence it will be seen that QYhen -the liquid in the bottle rises sufficiently high to place the isolated contact 23 and pipe 5 in electrical communication, the magnet 12 will be deenergized and the valve 7 allowed to fall and shut off the discharge, and such position of the valve will exist so long as the armature 27 is attracted. As soon as the bottle is removed, however, the circuit through the magnet 25 will be broken; but before the magnet 25 becomes deenergized by this interruption of the current the switch 16 will leave the contact 15 and thus maintain the breakage of the current through the magnet 12 and consequently prevent the latter from reopening the valve before another bottle is inserted.
In the practical construction of my apparatus shown in Figs. 3 and at the magnets and superposed mechanism are supported on a plate 28, which in turn is supported upon the upper side of the valveechamber 3, and.
is provided with a pair of standards 29, which carry a cross-bar 30 at their upper ends, to which the poles of the magnet 12 are secured, and upon this cross-bar is mounted a bracket 31, from which depends the magnet 25, and to which is also secured the switch 20, which, when the magnet 25 is denergized, drops into connection with a contact-point 32, and this in turn is connected to the conductor 21, the switch 20 being connected bybinding-post 33 to the conductor 19.
The isolated contact 15, to which the conductor 14 is connected, is carried by an arm 34, mounted upon the arm 17, and being adjustably held in position on the latter arm by thumb-screw 35. The arm 34 carries the switch 16, upon which is mounted the sup- P rt 22 f r he b le, which supp t i P e erably composed of non-conducting material. By this means it will be seen that the arm 34 may be raised and lowered on the rod 17, and thus cause the pipe 5 and contact 23. to project more or less into the bottle and thereby vary the quantity of liquid in the bottle. The rod 17 is preferably of metal, so as to serve as electrical conductor as Well as a upp and t is se r d in any su ble W y to the pipe 2, which is also of metal, for the a f t c al c ndu tivity- The i olat d Co tac 23 is prefera ly in the form of a tube or sleeve surroundingthe pipe 5, and between which tube and pipe is interpo d a u at n -sleeve .6.
I o er at the o a i n of he valve or its stem 8 may not carry the ends of the armature 11 away from the poles of the magnet 12, such armature 11 is circular, as shown in Fig. 4; and in order that it may be readily adjusted with reference to the magnet 12, it is mounted upon the valve-stem 8 between two jam-nuts 37.
The conductor 2a is carried to a bindingpost 38 on the plate 28, and thence to the contact Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is.-
