11 Claims.

This invention relates generally to .an attachment for a beer faucet of the type used in connection with dispensing draught beer; the invention being directed particularly to a device for removing the excess foam from draught beer as drawn intov a glass.

Heretoforeit has been the practice of bartenders to hold the beer glass in'one hand'beneath the beer faucet, to release the beer faucet valve with the other hand until theglass is full and to then pick up a separate and often unsanitary"beer spoon with said other hand and remove the excess foam from the glass. It often required a repetition of this operation in order to properly fill the glass with beer. Also, in

many instances the bartender removed more foam than necessary as the beer spoon" would dip into the glass below the rim.

It is therefore the principal object of our invention to provide a device for attachment toa beer faucet which, during the beer dispensing operation, will automatically wipe the excess and undesired foam from the glass; actuation of such device being accomplished by slight forward and backward motion of the beer glass as held beneath the beer faucet during the dispensing operation.

I a As a further object of our invention, it is our I .purpose to provide a. device of the character deates with very slight forward and scribed which is easy to operate and which operbackward movement of the glass.

,, 1 An additional object of our invention is to provide a device of the character described in which substantially all of the working. parts are enclosed and which is thus quite sanitary.

It is also an object of our invention to provide *a foam wiper of the character described which when in operation will tend to deflect the excess foam downward and into the usual foam receiv- 40' ing tray below the beer faucet.

A-further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposefor which it is designed. j

These objects we accomplish by means of such structure and'relative. arrangement of parts as will fully appear by a perusal of the following specification and claims. In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a perspective view of our device as mounted in connection with abeer faucet.

Figure 2 is a side elevation of the device as mounted in connection with a beer: faucet.

the forward ends of bars II and slidably project Figure 3 is a plan view with housing lid removed and partly in section.

Referring now more particularly to the characters of referenceon the drawing, the device comprises a pair of horizontally disposed L- shaped arms I disposed in spaced relation and having a substantially circular securing clamp 2 formed in connection with one end thereof. A resilient circular gasket or collar 3, preferably made of rubber, is disposed within the clamp 2 and engages about a beer faucet 4 in the manner shown. Tightening bolts 5 extend between the spaced arms I at a point adjacent the clamp 2 and are used to tightly engage the clamp 2 and gasket 3 about the beer faucet 4. These arms, when mounted in connection with a beer faucet, project rearwardly therefrom as shown.

A rectangular housing 5 is disposed between .and projects forwardly from the arms I, the lower ends of said arms being fixedly secured to 20 the sides of the gasket, or if desired the sides of the housing and the arms may be formed integral. The housing 6 is initially open at the top and rear end. A cover I is mounted on the housing and is formed with depending flanges 8 along its side and front edges. At its rear edge 'the cover is formed with a relatively long de- "pending flange 9 forming a closure for the initially open rear end of the housing 6.

A pair of elongated metallic cases I0, rectangu- 30 I lar in section, are disposed within the housing 6 a rack l3 along its inner side, the corresponding side of the case I0 being cut away to permit projection of the rack teeth therethrough. A horizontal ear I4 is struck out from the inner side of the other case I0 and forms the upper journal for a pinion I5 pivoted between the ear I4 and the bottom of the housing 6. 45

The pinion I5 is formed with an axially extended pin or stub shaft I6 which projects upwardly through an opening in the cover 1. A relatively long foam wiping blade I8 is fixed at its inner end on pin I6 and projects radially therefrom. This foam wiping blade is formed with downwardly and inwardly curved faces I 9 on 0pposed sides for the purpose hereinafter described.

Parallel rods 20 are mounted in connection with upper edge of the sion of springs l2.

through the adjacent ends of cases l0 and the end of housing 6. A beer glass engaging head 2| having a concave outer face is secured to the outer ends of rods 20, a glass locating lip 22 being formed in connection with and projecting outwardly from the upper edge of the head, on a level just below the lower edge of the blade l8. The rods 25 are of such length that when a beer glass is disposed with one side against the concave head. the glass will be disposed in proper beer receiving position beneath the beer faucet 4.

Operation In use our foam wiping device functions in the following manner:

The bartender takes the beer glass G in one hand and places the same with one side against the concave head 2! and with the upper edge abutting against the inner surface of lip 22. With the other hand the bartender controls the beer faucet valve and upon actuation of the valve (not shown) beer flows from faucet 4 into the glass. When suificient beer has been'dispensed into the glass to cause foam to rise above the glass, the bartender closes the beer faucet valve and then moves the beer glass forward a short distance causing rods 20 to be moved inward with resultant inward or rearbars H against the compres- This causes the rack l2 to rotate pinion M resulting in the foam wiping blade i8 swinging through an arc of approximately 180 or from its normal position to a. like position. on the other side of the device. Movement of the glass backward permits the blade to ward movement of swing back to its normal position. With such arcuate movement of the foam wiping blade I8,

the downwardly and inwardly curved faces of the blade wipe across the top of the beer glass and remove all excess foam, the curved faces I9 deflecting the foam downward into the foam receiving tray below the beer faucet.

After the initial excess foam removing operation the bartender can then dispense more beer into the glass and again repeat the foam remove ing operation if necessary. As the foam wiping blade i6 sweeps across the beer glass close to the upper rim thereof the removal of all'excess foam is assured and without the removal of the desirable foam which remains below such rim. By employing our novel device the number of movements required to properly fill a beer glass is materially reduced as the bartender need not remove his hands from either the beer glass or beer faucet valve as is now necessary when a separate beer spoon is used.

From the foregoing description it will be readily seen that we have produced such a device as sub stantially fulfills the objects of the invention as set forth herein. 7 a

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims. I
