JOHN WELLS SI-IEPII'ARI) AND FREDERICK AUGUSTUS JONES, OF WAGGA WAGG-A, NEW

SOUTH wALss, AUSTRALIA.

FAUCET ATTACHMENT.

To all whom it may concern:

Be it known that we, JOHN WELLS SHEP- HARD and FREDERICK AUGUSTUS J ONES, subjects of the King of Great Britain and Ireland, &c., residing at Wagga VVagga, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Improvements in or Attachable to Taps or Cocks; and we do hereby declare the following to be a full, clear, and

exact description of the invention, such as,

will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to taps having spouts or nozzles, particularly those for milk and liquids which should be kept from contamination. To this end we use a guard or protector which is normally closed over the nozzle, so keeping off dust, but which can be opened. This protector shield or lid, is of any suitable size and shape, forming a hinged or suitably connect-ed door which normally will not open except when the tap or valve plug is operated. It then 3 opens by its weight, or by the aid of a spring or other obviously available device, leaving the nozzle clear for the discharge of liquid or material. When a springis used to open the guard it has the advantage that it will hold it specially wide open as prearranged, and when liquid leaves the nozzle the door will be well out of the way, and will not cause splashing. When the valve is closed as by turning the tap plug an attachment to or arm from the plug causes the guard or door to shut and holds it so. The arm which we use as a guard closer is in our preferred construction adjustable, with a springy beveled tongue or end. Around the nozzle we secure an enlargement to form or carry the door seat.

There may be added means for locking the door or guard to the nozzle enlargement. Referring now to the drawings herewith which illustrate a construction we may use.

Figure 1 is a sect-ionalside elevation, and Fig. 2 a front elevation of a tap having a door or guard shown in closed position by full lines and in open position by dotted lines. Fig. 3 shows details of a nozzle and door in vertical section, and F ig. 1 shows details of a door and its hinge and actuating arm in plan view. Fig. 5 shows two actuating arms usable in combination, and Fig. 6 shows a modified form of actuating arm made of Specification of Letters Patent.

Application filed March 12, 1912.

Patented Apr. 8, 1913. Serial No. 683,387.

spring wire with means for attachment to the tap plug.

In these drawings 1 indicates any suitable passage way, of or to a tap, having a nozzle 2 with eXtremityS, and plug 4, having any suitable base as a screw threaded one 6, with a nut or other suitable fastening 8. Part of plug 5 is made angular or adapted to be fitted by the rear portion 13 of an arm or door closer 13. The said rear portion has a hole or slot 13 elongated to allow of adjustment of arm 13 more or less forwardly so that its springy front part or tongue 13 shall pass suitably under the door 12 which guards the nozzle. The tip 13 of the tongue presses the door 12. This tongue is so beveled that it will readily pass under the open door and swing it into its closed position when plug 4 is rotated to shut the tap.

7 and 7 indicate washers, but these are details which can be varied at will.

9 is a collar which flares or enlarges outwardly, and at the upper part is secured upon the nozzle in any convenient way, so as to be removable for cleaning or it may be integral with the nozzle as for example in Fig. 3.

Arm 13 is ordinarily, but not necessarily, springy or of the shape shown.

By having its top split as at 9 and provided with perforated lugs 10 to receive a binding screw 11 or the like the collar can be firmly held on. Or the collar may be screwed on as are other hose fittings.

The edge 12 of door 12 is ordinarily beveled to meet a seat of corresponding form on the under side of the collar.

We provide a suitable projection 9" as on collar 9 to form part of a hinge, the restof which is formed by a projection 12 from the door 12. A spiral or other suitable spring 12 is provided, so that as soon as arm 13 is swung clear of door 12, the latter will open.

As some tap plugs turn right around, we provide in such cases a double arm 13, made either as in Fig. 5 of two pieces which can be adjusted, each having a hole 13, or the double arm may be in one piece. When the tap is turned right around one or other of the two arms will close the door each time the plug is brought into the position which shuts off the milk or other liquid.

The bent wire arm 23, in Fig. 6 is simple and effective. It is connected to a plate or washer 23 as by being passed through side holes 23, the plate having a hole 23 to fit over the square or suit-able part 5 of plug 4:.

The collar 9 projects any suitable distance below nozzle end 3, so that the closed door does not touch the nozzle, and this arrangement has other advantages also.

What We claim Letters Patent for United States is 1. In a tap Protector, the combination of a closure for the tap nozzle, means for yieldingly maintaining said closure in open position when the tap is open, and means secured to the tap for clamping said closure in closed position when the tap is closed.

2. In a tap protector, the combination of a closure for the tap nozzle, means for yieldingly maintaining said closure in open position when the tap is open, and means adjustably secured to the tap for engaging said closure to shift the latter to closed position during the closing movement of the tap.

3. In a tap protector, the combination of: a closure for the tap nozzle, means for yieldingly maintaining said closure in open position when the tap is open, and resilient means secured to the tap for shifting said closure to closed position during the closing movement of the tap and for clamping said closure in such closed position.

4. In a tap protector, the combination of a closure for the tap nozzle, means for yieldingly maintaining said closure in open position when the tap is open, and a pair of oppositely-extending arms secured to the tap for shifting said closure to closed position during the closing movement of the tap.

In testimony whereof: we aflix our signatures in presence of two witnesses.
