REFRIGERATING-COUN TER.

Specification of Letters Patent.

Patented Nov. 2, 1909.;

Application filed October 5, 1907. Serial No. 395,987.

My invention is illustrated in the accompanying drawings in which,

Figure l is a transverse section through the counter showing the bottom and the top part separated. Fig. 1a is a modication of the door, shown in Fig. l. Fig. 2 is a modilied form of the countershown in perspective view. Fig.' 3 is a detail side View of the ribs holding the glass plates of the counter top. Fig. 4 is a plan view thereof. Fig. 5 is a longitudinal vertical sectional view of a part of the lower portion of the counter.

The particular advantages of my counter are that a perfect and constant air circulation is obtained owing to the manner -in which part of the refrigerant is disposed, and the convenient manner in which the counter may be refilled and taken apart for cleaning purposes.

'In Fig. 1 of the drawin s 1 is a casing of suitable material, prefera ly wood, braced throughout by ribs 2 and containing a compartment 3 disposed so that an insulating air space 4 is formed around it. The inside of the outer casing 1 and the outside of the inner compartment may besides be insulated'A with any kind of suitable insulating material 5 such as for instance paper, felt or the like. The inside of compartment 3 is lined with a suitable water-proof lining 6 prefer'v ably galvanized sheet metal thus forming a pan within compartment 3. The bottom of com artment 3 is slantingly disposed toward the fiont of the counterl and is provided with a drain 7 at its lowest point to drain off moisture collecting at the bottom. Transversely to its longitudinal axis are provided Within compartment 3 a suitable number of removable supporting walls 8 dividing the compartment mto a suitable number of sections communicating with #each other through opening 9 provided at vthe lower end of each wall so that the moisture collecting in the compartment may flow to drain 7 from all sections. At their upper edgewalls 8 are provided with notches or recesses 10 in which refrigerating pipes 11 containing the refrigerant are disposed. so that these pipes are run in parallel to the longitudinal axis' of the compartment and are s upported-by walls 8. At least one of the refrigeratlng pipes 12 is disposed at the extreme top `of the rear or high wall of the compartment and is referably the first through which the refrigerant passes before passing through pipes 11 disposed in wall 8. Pipes 11 are covered by-floor 13, also slanting toward the front of the counter on which the goods to be displayed are placed and which may be provided with a lip 14 at its lower edge i order to prevent the goods from sliding from the licor. In order to facilitate cleanin Acompartment 3 floor 13 is made prefera ly removable.

At the lower end of supports 8 on the upper edge are provided the spacin lips 15 against which rests the floor -13 an this floor 13 is suiiciently narrower than the compartment so that passage ways 27 and 28 respectively of suitable' width are left between the floor and the lower and upper vertical walls of the compartment, upper passage ways 28 being preferably wider than the 1- ameter of refrigerating pipef12, which 1s dlsposfd directly above the passage way. p

Compartment 3 is covered with a glass' cover 17 (shown removed in Fig. 1) which may be fastened tight to the upper edge of compartment 3 by any suitable well known means. The cover consists of a frame 18 for supporting the glass which protects the products displayed in the counter and is preferably opened from the rear by means of doors 19 'and 2O which .may slide in grooves 21 and 22 respectively.l These doors are easily and quickly opened and may be removed entirely on busy days with very little loss of eifectiveness of refrigeration. The doors are 1'preferably hung on hinges 29 as shown in Fig. 1, in which case they are preferably swung from the top so they will open by pushing same insidethe glass cover. The top of cover 17, as may be seen from the drawings, inclines forward, which follows the general' outlines of the upper refrigeration J-K. The cover may have.

double glass panes but consists preferably of only one thickness as there is a tendency for moisture to accumulate between the two f panes of glass thus concealing to a considerable extent the goods displayed.

The manner in which the counter operates is as follows: The pipe V12 disposed at the upper rear edge of compartment 3 cools the air surrounding it, thus increasing its weight so that the air will besent down by gravity in the direction Aof arrow A through theopening 28 into the space underneath iioor 13, which in turn will cause the air. contained therein and cooled by pipe 11 topass out through the passageway 27 at the lower end'of iioor 13 in the direction of arrow B. Thus the air in the counter is'kept moving continually in the direction -indicated by soap and. hot water, whereafter the latter'- the arrows A-B, the moisture contained' in the airfbeing largely picked up by the pipes 11 so that the air is constantly kept dry as well .as cold. At certain periods all the goods may b e removed, door 13 taken out, and the compartment be cleaned with may beA easily drained ott' bylmean's of drain pipe 7.

While I have shown anddescribed a par-- ticular r/form of `refrigerating counter I do `not wish to limit myself to this one form since various modifications may be made thereon Without departing from the spirit of my invention. f

I Vhave shown for instance in the modified form illustrated in Fig.-2 two refrigerating pipes 12 near the upper edge ofthe rear wall of the compartment. Furthermorey the counter maybe built' without a removable.

cover 17 such as shown in Fig. 1. As may be seen in Fig. 2 the top glass panes 23 and 24 and the front panes 25 may be made removable i-n order to place goods into the counter for which purpose the front panes 25 are disposed slidingly grooves 30 of brackets 26, while the top panes 23 and 22E may rest on'top of brackets 26 and belifted off if necessary. The advantageof this form is that the counter may be refilled from thel front by removing one of the front'panes while the products may be taken out throng the rear door as described before. f
