VINCENZO BONZAGNI, OF BOSTON, MASSACHUSETTS.

BEVERAGE-DISPENSING AND PIPE-CLEANSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 684,041., dated October 8, 1961; Application tiled January 7) 1901, Serial No. L12,433. (No modeh To all whom it iii/ay concern:

ge it known that I, VINCENZO BONZAGNI, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Irnprovements in Beverage Dispensing and Pipe-Cleansing Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in Which- Figure l is a view showing a number of beverage-receptacles, their draft and pressure pipes, and the branch pipes for cleansing the draft-pipes, all permanently connected in accordance With this invention. Fig. 2 is a local section enlarged.

On the condition of the retailers draft and dispensing pipes largely depends the pure, bright, and fresh or theY indiiferent or bad state of the beverage by the time it reaches the individual Who drinks it, for it is Well p known in serving not only malt liquors, but

soda, milk, cider, and fancy tonic drinks when conducted through metal pipes from barrels or other receptacles to draft or supply cocks that sooner or later the interior of the service-pipes becomes coated with the sediment in said liquors, and Where the 110W is temporarily suspended-as, for instance, over night, or from Saturday night to Monday morning when not in use, or during the day Where the demand is small or intermittent-the pipes become foul and the impurities therein taint the beverage and cause much sickness, the origin of contagious diseasessuch as typhoid fever, diarrhea, and cholerabeing constantly traced to foul beveragepipes. To remove this public danger is the obj ect of my present invention ,which particularly relates to certain apparatus for cleansing beverage-pipes for which United States Pat` ents No. 353,413, dated November 30, 1886, and No. 598,301, dated February 1, 1898, Were granted to me. The construction set forth in Patent No. 353,413 admitted of the lthorough purification of the interior of each draftpipe separately, but only one at a time. The

y construction set forth in Patent No. 598,301

a tank containing a cleansing agent, said main cleansing pipe having a series of branches corresponding in number to that of Ithe draft-pipes. This latter construction greatly facilitated the cleansing operation; but the uncoupling of eachV draft-pipe from its beverage-receptacle, the coupling of each draft-pipe to its corresponding (contiguous) cleansing branch, and the recoupling of the draft-pipe (after being cleansed) to its beverage-supply in order to restore its flow to the place of serving were rendered necessary, said three successive steps, however, occupying much less time and being performed more conveniently than the cleansing of cach pipe separately.

This invention has for its object to economize the time and labor involved in the said manipulations of the draft-pipes; and my present invention consists in the combination and permanent attachment of all the draftpipes with their corresponding cleansing brauch pipes and in providing each draftpipe and each cleansing branch With a separate and independent controlling stop-cock, which may be opened and closed to permit either the cleansing operation orthat of dispensing the beverage, as occasion requires.

My invention also consists in the combination and permanent attachment of the pressure pipes with the cleansing branches Whether the draft-pipes are or are not permanently attached to the latter and also consists in an auxiliary receptacle for containing carbonio-acid gas or compressed air in combination and connected with the cleansing-receptacle, suitable pipes and controllingcocks being provided each and so located that either'the cleansing of all the draft-pipes may be simultaneously or singly performed or discontinued, the pressure on the beverage be applied or suspended, and the flow of the beverage be stopped or restored without the interference of any one function With the other, the construction and operation of the several features of my invention being hereinafter particularly described, and set forth in the claim. l

In the said drawings, A A, dsc., represent a series of kegs for containing the beverages IOO to be dispensedfor instance, beer, ale, tonic drinks, soda, milk, Sac-said kegs'being conveniently located in the cellar of the retailer on a raised platform B. The draft-outlets of `the kegs are controlled by plugs ct, having faucets ZJ for opening and closing the same in the usual way, said plugs having outer screw-threads for the reception of the couplings c of the draft-pipes C C, tbc., Fig. 2.

D is a tank, at the bottom of the inside of which is a perforated partition or strainer CZ, Fig. 1. The top of the tank D is provided with an opening having a cover e, through which opening is introduced any suitable cleansing agent soluble in Water, such as salsoda, chlorid of lime, potash, dre. 7L is an inlet-pipe, through which Water is supplied to the top of the tank, said inlet being provided with a controlling-faucet.

t' is a pipe for the admission of compressed air or carbonio-acid gas contained in a tank E, said pipe leading into the top of the tank D through an inlet G and being provided with a governing-cock, by which pressure is let on or shut oif therefrom.

At one side of the bottom of the cleansingtank D is an outlet 7c, controlled by a faucet. With this outlet 7c is coupled one end of a cleansing-pipe G, extending vertically downward to a horizontal main cleansing-pipe H, having a series of branches Z Z Z Z, rbc., correspending in number and permanently attached to the bottoms of the several draft (or beverage-supply) pipes C C C, the., the outer end of each cleansing-branch Z and the bottom of each draft-pi pe C where they are connected being provided with a governing-cock m, the point Where the bottom of each draftpipe diverges horizontally to its keg connection being also provided with an independent governing-cock n. (See Fig. 2.) This permanent attachment of the draft-pipes with their corresponding cleansing branches and locating the points of union of the draftpipes with their keg connections on the same coupling carrying the cleansing branches is one of the vital features of this invention, as by such permanent connection, tbc., all uncoupling of the draft-pipes from their keg connections is dispensed with, (when the keg is not empty,) the coupling of the draft-pipes to their cleansing branches and the recoupling of said draft-pipes to their keg connections to restore the flow is rendered unnecessary, and consequently the time, labor, and inconvenience involved in these operations incident to the construction set forth in my Patent No. 598,301 are entirely avoided.

The kegs are located at such distance apart that ample room is afforded for the passage of the attendant Whose office it is to manipulate the several controlling-cocks during the operations of cleansing the draft-pipes and restoring the flow of the beverage and for the disconnecting and removal of the empty kegs and the locating and coupling of full ones. Also at the bottom of the cleansing-tank D, on the side opposite the outlet Z1, may be located, if desired, another ou tletp, from which the cleansing liquid may be drawn for use in washing utensils of various kinds and for general domestic cleansing requirements, said outlet being controlled by a stop-cock, Fig. 1. The capacity of the tank must be adequate to contain su flicient cleansing liquid for thor-l oughly cleansing all of the beverage-pipes C at one and the same time Without refilling the tank and not merely a sufficient quantity for cleansing each pipe separately. The Water in the tank is preferably heated by any medium which happens to be most convenient-for instance, by gas-jets from a burner I, located under the tank, Fig. l, or by an oil-lamp or by electricity through a resistance-coil within the tank, the efliciency of a cleansing liquid in a hot state being thereby increased, care being had to remove the cover in the top of the tank and close the pressureinlett' before the heat is applied. The flame from the burner I is conveniently regulated by a pair of screw-threaded nuts 5., turned over the threaded exterior of said burner, the description of the same being set forth in my Patent No. 598,301. The shape of the tank will be governed by the form and position of the space in which it is to be located, and it will be desirable to locate it Within convenient reach of the person using the apparatus.

zu is a support for holding the pressurepipes in position when their lower coupling ends are detached from the tops of the kegs. t t are the pressure-pipes, leading from the common pipe H to the tops of the several kegs A. The bottom of each pressure-pipe is provided with a stop-cock u.

r is a pipe leading from the tank E to the pipe H, and s its controlling-cock.

Operation To cleanse all the draft-pipes simultaneously Without the necessity of uncoupling, close the valve n at the bottom of each draft-pipe C to check the further supply of the beverage from its keg. Let the pressure act from the tank E through the pipe r by opening the cock s thereon till the contents of the draft-pipes are discharged through their draft-cocks at the bar. Then shut off the pressure from the kegs, open the valve m, which controls communication between each cleansing-branch Z and its draftpipe C, open the outlet-cock 7f3 of the cleansing-tank, and continue the floW of the cleansing liquid through the interior of all of the draft-pipes until the sediment deposited and accumulated therein is removed and discharged through the draft-cocks. Then to remove the taste of the alkaline solution let fresh Water run through them by openin g the cock of the Water-supply pipe h. To restore the iow of the beverage, close the outlet 7c of the cleansing-tank, closing all the Valves m of the cleansing branches, open the valves fn, of the draft-pipes leading to their keg connections, and finally open the several cocks of the pressure-pipes.
