Specification of Letters Patent.

Patented Feb. 26, 1918.

Application filed September 17, 1915. Serial No. 51,209.

To all whom it may concern:

Be it known that I, ADELARD AMYoT, a subject of the King of Great Britain, and

residing at 590 'Valois street, Montreal,

Province of Quebec, Canada, have invented certain new and useful Improvements in Show-Cases or Refrigerators, and do hereby declare that the followin is a full, clear, and exact description of t e same.

This invention relates to cases for the reception and preservation by cooling of perishable commodities and an object of the invention is to provide an improved mode of ventilation for such cases.

Another object isto improve the construction of such cooling cases.

Another object is to provide an improved cooling case which may be used with or without ice.

Further objects and advantages will be hereinafter more fully described and particularly pointed out in the appended claims.

For full comprehension, however, of my invention, reference should be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate the same parts and wherein:

Figure 1 is a perspective view of the show case employed with an ice-chest;

Fig. 2 is asimilar view of the case without the ice-chest;

Fig 3 is a horizontal section on line 33 Fig. 5;

Fig. 4 is an enlarged transverse section of the upper part of the sl10wcase;

Fig. 5 is a longitudinal vertical section on line 55 Fig. 6;

Fig. 6 is a transverse vertical section on line 6-6 Fig. 5 and Fig. 7 is a detail perspective illustrating the corner constructions with the parts disconnected.

While my invention is applicable to refrigerators I have illustrated it in connection with a show case which consists preferably'of base 2, corner posts 33, 41, top frame 4, shelving 5 and rear doors 6, provisibn being made for the cooling of the case either by ice or by the admission of cooled air, as will be presently described.

The front, ends and top of the cooler are double walled, the showcase having spaced,

sleets 7 and 8 of glass at the front and sides and spaced sheets 9 and 10 of glass at the top and I have provided an improved means of ventilation for thespaces between the inner and outer walls and the interior of the case which preferably consist of vents 11 extending from the interior to the exterior of the case and vents 12 and 13 respectively extend ing from the spaces between the inner and outer walls to the exterior of the case.

In the preferred form the vents 12 extend substantially horizontally from the space between walls 9 and 10 outwardly to the atmosphere through the top frame at suitable intervals around the'latter and the'vents 11 extend from the interior of the case diagonally upwardly through the top frame and respectively communicate with one of the vents 12 between the ends of the latter while the vents 13 extend from the spaces between walls 7 and 8 upwardly through the top frame and respectively communicate with one of the vents 12 between the ends of the latter and at the junction of vents 11 and 12. In this way a three-way vent is formed at the front and ends of the case and a twoway vent at the rear so that the ascending heated or contaminated air in both the interior of the case and between the inner and outer walls is continuously carried off and the full efficiency of the cool air admitted to the case utilized for the preservation of the contents of the latter, the disposal or elimination of heated air being accelerated by the'union of the different vents in that the passage of air through one tends to create a suction in the other and so sucks the air therethrough.

Vertically spaced supports 14 for the shelves 5 extend transversely across the end of the case from front to rear corner posts to which they are secured by screws, the shelves, which are spaced from the front and rearof the case to facilitate circulation, resting loosely upon and extending between these supports and additional supports 15 screwed to pairs of uprights 16 disposed toward the center of the case those of said.

uprights at the rear extending between and being screwed at their ends to the base and rear portion of the top frame for which they constitute a brace to prevent sagging thereof. The front uprights 16 are spaced from the inner front wall and are secured at the bottom to the base 2 by screws, the

the uprights and brace same against twisting. The lower ends of the uprights 16 are braced by pieces 17 screwed to the base and extending transversely of the case between the front and rear uprights of each pair and by pieces 17 screwed to the base and extending between the front upright and front of the case, said pairs of uprights being spaced longitudinally of the case to provide a central space for the accommodation of an ice-chest 18.

There are preferably three doors 6 which are slidably mounted upon tracks 18 and individually of less width than the case but adapted to collectively completely close the back of the case and may be moved to provide an opening giving access to either end of the showcase or as shown in Fig. 3 the space between the uprights 16 so that" the ice chest may be inserted or removed.

When the ice-chest is inserted it rests loosely upon shoulders 19 presented by the braces 17 and is therefore spaced upwardly from base 2, the top of the chest being provided with a perforated cover 20 and the end spaces of the case so that with the ends of the shelves spaced from the front and back of the case, a thorough and complete circulation throughout the case is secured.

The front of the ice-chest is spaced from the inner front wall of the case, being preferably flush with the outer uprights 16 and the supports 15 extend outwardly from the chest and support smaller shelves 23 extending across the front of the chest, movement of the chest in a forward direction being limited by a stop24 which rests loosely upon braces 17 and constitutes a lower shelf which with the other shelves 5 and 23 can be removed.

' A water outlet 25 from the chest through the base is provided but if it is desired to use the case without an ice-chest the latter may be removed, in which case the outlet 25 1s plugged and chilled air admitted to the case through pipe 26'which inay lead, from the outside of a building opening 27 disposed about the center of base 2 and which is closed by a plug or cap 28 when the ice-chest is utilized.

When the case is thus cooled without the aid of ice the central space is filled in with shelves29 upheld by the supports 15, the perforated cover20 of the ice-chest being placed upon the shoulders 19 flush with stop 24 and while serving as a lower shelf also acts as a baflle for distributing the chilled air laterally through vents 22 as it enters through opening 27.

The several units of the showcase are made of standard size for convenience of for instance to an.

renewal and are for the most part formed to strongly interlock and fastened in place by screws only so that the case can be readily taken apart and packed in a small space for transportation, the preferred detail construction being as follows:

The base 2 of the showcase is depressed at the front and ends to receive lower frame pieces 30 screwed to the base and having the upper sides longitudinaly grooved or stepped to form inner and outer shoulders 31 and 32 respectively, the adjacent ends of the-front and end frame pieces being spaced from each other to accommodate front corner posts 33, the opposite sides of each of which are longitudinally grooved to form inner and outer shoulders 34 and 35 respectively, corresponding to and continuing upwardly from the shoulders 31 and 32. The spaced ends of the lower frame pieces are transersely grooved to form stepped projections 36 fitting snugly into the grooves of the front corner posts and interlocking the members. The lower ends of the front corner posts are each reduced to form a shoulder 37 and a 'downwardly extending projection 38, the shoulders resting upon the base and the projections being set flush with the edges of the base in front corner notches 39 and held in place by screws.

'The rear corners of the base are notched at 40 to accommodate the lower reduced ends of the rear corner posts 41 which are,

flush with the edges of the base and screwed thereto, the inner side of each of such rear corner posts being longitudinally recessed at 42 to receive the edges of the doors 6 and form a tight closure thereby. The front side of each rear corner post is longitudinally grooved or stepped to forminner and outer shoulders 43 and 44 respectively, corresponding to and extending upwardly from the shoulders of the lower end frame place by beading 50, the outer sheet 10 resting upon the upper side of the top frame and being held in place by a removable strip 51 screwed to the rear piece 52 of the frame and having an undercut portion for the reception of the rear edge of sheet 10 which latter and sheet 9 can thus be readily removed from the outside merely by loosening the strip 51 and beading 50.

The top frame includes front and end pieces 4, the lower sides of which are longisecured together by screws, the outer cor-- 11ers so formed resting upon and being screwed to the front corner posts which are inwardly stepped as at 56 to accommodat the shoulders 53 and 5 The underside of the rear piece 52 of the top frame is longitudinally recessed at 57 f0 loosely receive and guide the tops of certain of the doors 6, the others being guided by a retaining strip 58 screwed to the back of the rear'piece 5 2.

The opposite ends of the rear piece 52 rest upon the rear corner posts and are each undercut to form a shoulder 57 abutting against the inner side of the adjacent post, the upper side of the ends of the rear piece being depressed at 58 to receive the projecting ends 59 of the' end pieces 4 of the top frame which are undercut to form shoulders 60 and 61 respectively abutting against the rear piece52 and rear corner posts 41, the several members so interlocked being secured by screws which extend down through the frame pieces 52 and 4 into the corner posts.

Owing to the overlapping or interlocking joints a showcase of the above description is particularly suited to act as a receptacle for the preservation of perishable commodities and in view of the facility with which the parts of said case can be, disconnected, it can be readily taken apart and compactly packed for transportation and again as sembled with a minimum amount of labor.
