To all whom it mer/'concern Be it known that I, JOHN F. BARG- nAUssN, a citizen of the United States, re-

sidingfat 6621 Firsty Street NW., Takoma'.

preservingby ch' j' 'ng of perishables, -such fasmeats and vcgeahles, while the saine are -on public displayasin the retail market or the like. y f J, I `More specifically/the invention seeks to i provide a refrigerated display counter of neat and attractive appearance, relatively 1 simple and inexpensive of, construction vand maintenance, in which thearticles to be preserved and displayediinay be positioned in a chillingchainbcr in full and convenient View of the prospective purchasers and counter attendant and readily accessible to :the latter,and in-ivhich an automatically in- Y' 5duced`,..r:ted,' and Ltleansed preserving agent lcirculation` is constantly `maintained -in a I manner insuring:properpreservation` of the articles and rendering possible a structure -in which` the necessity 'of all unsightly super-structures Iand refrigerating piping and coils is eliminated.

` y pWith the above and other objects in view 'that will hereinafter appean'the invention further resides in those novel details of construction, combination and arrangement of ,such products as fresh meats. i vcounters equipped with mechanical` refrig- `Vparts, all of which will be first fully. de-

scribed, then be particularly pointed out in l l the appendedv claims, reference being had to the accompanying drawing in which:-

In the l.common types of refrigerateddsplay counters now in use are usually om ployedja series of cooling coils. These coils,

to be advantageous,'niust be positioned adjacent the displayed products and hencea're as much on display as the products them;n selves, which is not desirous.

l/Vhen the cold brine is circulated through. the coils they become ice coated and the ice 65' f acts, in a degree, to retard refrigerating efliciency. `While it may he so that Ain. some types of counters, and in display Windows., 'coils of frost covered pipe attractively arranged may act as an advertising medium,

any advertising value that may be attributed thereto is lost in considerationv oi the waste of-space and ideal ret'rigerating con-v dition occasioned by the position-ing of the coilstar enough vaway from the product to overcome all possibility or" contact which results'. in unsightly discoloration of the coils. Moreover, since heat alone will def stroy Vmost disease germs, and not cold, the

common plans of coil installation lcause 80.

them to become harboring places for such` geruis. Still further, when such coils are placed near the glass top, which is the most advantageous location for them, it is necessary to suspend a pan under them to catch '85 the drippings from the melting ice on the coils. Such arrangements not only obstruct,

to a certain extent, the full display of the 'l products, but interfere withv the pro er cleansingv of the display section and quently present an unattractive appearance.

Also in such systems the circulation of they i cold brine through, the coils refrigerates the display section but does not provide for an automatic circulation of air therein, which is quite important.

It is to the deficiencies of construction and arrangement above alluded to thatl 'have addressed my efforts, with the r'esult thatl *y HESSUED have developed a display counter which I' 1ct lind, after considerable experimentation and a series of practical tests, to be highly elficient and practical and in which all the products are glass enclosed and conveniently displayed without obstruction to view by or displeasing etlects of any coils Whatever,in

which means is provided for proper cleans` ing, resulting in a greater degree of sanitation and attractiveness than heretofore possible, and in which theV refrigeration is so accomplished that a thorough washing and effective circulation of cooling air is antofrom 45 to downwardly-inwardly at each end thereof and an upwardly di- :1.3 ing l, and a 40 the chamber F iiiatically maintained. lliiaddition to'the features of sanitation present in my counter, it i's'easily possible to maintain a teinperature in the display chamber thereof pf 500 Fahrcnheiin all seasons of the year.

In the practical development of my iiivention I provide a suita ly supported ce ment to i Av which forms the floor of and 1G upon w iich is built-the super-structure or glass -enclosed cabinet that forms the chilling Vand display chamber hereinafter again referred to.

The top or .looiVA is providedwith a directed opening B rected opening C centrally of the len h thereof, the plan of the said top or floor eing that of a long substantially narrow rectangle.

'lwo cylindrical pipes or chiots D are sup- )ortcd longitudinally beneath the top A and have their entrance ends each'beneath and in communication with an end opening B '25 and their discharge ends iii-spaced and opposed relation beneath the central opening C for a purpose that will later be apparent. It will also be noted that the pipes or ducts D incliner slightly toward their discharge ends, the purpose for Which will also later G beneath the slightly extended discharge ends of the pipes 'or ducts D, and a brine drain pipe'H communicates with andgextends downwardly therefrom, a brine return pipe 'I being connected with the -said drain pipe for a purpose later to be descril ed.-l

A brine supply pipe J extends upwardly into each air receiving clianiber Ff" and-is 'alic equipped as at K to facilitate control mi of the ow of brine therethrough.

A Each pipe J is ittedat its end with a right angled elbow L which turns axially into the entrant end of the respectivepipe L 'or duct-D -to serve as ay connection for a fai spray nozzle M which ture suitable for eJecting into 'the duct,y

may be of any struetowaijd the .discharge divided conical spray for contacting the end" thereof, a lfinely of brineof an area i the respective C, the inner Walls forming and the end walls forming in Figureis made deep enough to` 15 accommodate the positioning of a drain pan the displayed `.of to facilitate i wall of the said delict' hmughou its Whole inside diameter. i

Where exposed, the pipes or ducts D are. suitably heat insulated as atV N. I

The supporting walls, end and side, .for supporting the top or floor A inay bc constructed of hollow tileand cement and be suitably heat insulated and glazed tile finishedaccording to taste. Y

Each end wall is provided with an air` induction opening O which con'in'iunicates with the respective air receiving chamber E beneath the opening B and each opening 0 is screen covered and controllable as to the degree of opening thereof in any approvedI manner, as by a rotatable solid cover )ortioii as diagrammatically indicated in ig-v ui'e 3 of the drawing.

` A loiivered metal -frame P is positioned in each end opening B and the slats of each thereof are directed downward and toward counter end. A louvered is positioned in the central opening C and the slats at each side of the medial line of this frame are directed upwardly and toward the respective counter ends. These frames aid. in directing the metal frame Q course of the coolingair and facilitate'the maintaining of the center-to-end cooling air circulation at each end of the counter. f

A supporting balile It is positioned above (about 4) thecenter opening C, the stip-- ports therefor being at front and back so as to leave `open ends for directing a dow ofv cooling air toward each counter end. Ob-

viously this'balile serves as a support 'for products placed thereon and also as a means for directing Icirculation of the cooling air structed and arranged as shown, the desiredV circulation of the and, as the member 4R servesalso for a productsupportythe maximum area of cooling and dis of plan imen'sions is obtained and in a inanner obviating all-necessity of obstruction ofv display by anyineans whatever.

as stated. By providing this member, concooling air is provided for lay chamber possible lconsiderate lio The suitably heat insulated walls for en'- closing ,the lower pa ofand supporting the counter are generally designated S.

Upon the top A is built the glass enclosed superstructure T which eiicases the cooling and display chamber in a manner affording convenient and chasers. This supeistructure ,is suitably equipped with slide dooisU at the rear there! ready access tov the'intcrior of the display chamber.' f

`Warm airdischarge openings-'V are provided at high points of thesuperstructure and, like rthe air 'induction openings O are A. storage compartment XV yifledby the utilization of suitably lient ins` .ted w-"all and iloorsectons as illustrated.
