REFRIGERATOR-WAGON.

Specification of Letters Patent.

Patented Apr. 8, 1913.

T 0 all whom it may concern Be it known that we, JOHN C. RAUM and JOHN J. RAUM, citizens of the United States, residing at Baltimore, inthe'State of Maryland, have invented certain new and useful Improvements in Wagons, of which the following is a specification;

Our invention relates to refrigerator structures adapted to contain melting ice, and more particularly to such structures when applied to devices commonly known as ice cream wagons.

The main object of the invention. is to provide an anti-drip wagon of improved construction, in which the parts may be removed for cleaning or repair more readily than in prior devices of this character.

With the above and other minorobjects in View, the invention consists in the construction and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, in which:

Figure l is a longitudinal vertical section through our improved refrigerator wagon; Fig. 2 is a section on the line 22 of Fig. 1, parts being in elevation; Fig. 3 is a central transverse section through the' wagon; and, Fig. 4 is an enlarged sectional detail showing our preferred form \of heat insulation. v

Referring to the drawings in detail, the Wagon frame comprises the usual side sills 1, having rabbets 2 in which are seated the side walls 8 and 3 of the front and rearbody compartments A and B, which are spaced apart to provide a passageway, as shown in Fig. 1. The compartments B and A also have the end walls; 4 and 4, and suitable tops or covers having hinged doors 5 and 5. These covers and doors may be of the construction shown in our co-pending application, Serial No. 694,116, filed April 30, 1912.

Each compartment, is provided with a bottom 6, which bottom is of a size to snugly fit between the side walls 3 andis su ported by means of cross-sills 7 and 8, whic crosssills are secured at their outer ends to the under side of the side sills 1 by means of Refrigerator- 'metal 10 laid over a suitable layerof heat lnsulatmg material as hereinafter described.

The edges of the bottom sheet 10 are turned up as clearly indicated at 13, and the lower edges 12 of the side wall covering over-lap the upturned edges 13 of the bottom. .Any water accumulatin on the side wallswill therefore trickle o into the bottom of the .compartment. v Disposed between the compartments A and B is a drip pan 14, the side edges 15 .and 15 of-which rest upon-the cross-sills 8 and 8, respectively, and are gripped be tween such sills, and the bottoms 6 and,6

of the compartments. In other words, such bottoms over-hang the edges of the pan. The end edges of the pan lie within the sidesills 1, as indicated 1n Fig. 3, but are unattached thereto. The drip pan is provided with one or more discharge spouts 17 at its center, which is the lowest point, such spouts being so located as to prevent the water dripping upon any part of the running gear of the vehicle. Eachbottom 6.and 6 carries at its lower edge a discharge spout .18 and 18, respectively, which over-hang the pan. A removable running board 19. preferably extends between the, side sills in the space between the compartments A and B, such board resting at ltS ends in the rabbets 2.

It will be observed that by taking off the nuts 9, the sills 8 and 8' can be lowered, and with them the pan 14;, and by similarly removing the sills 7 and 7' as well, the bottoms 6 and 6 can be lowered away from their respective compartments. In this way both the drip pan and the bottoms of the compartments can be removed without in, any way dismantlin or disturbing the other parts of the wagon ody structure.

In Fig. 4, we have shown an vim roved method of constructing the walls and hottom of our refrigerator compartments, which methodhas proven very satisfactory in practice. On a suitable base 4, such as a board, we first place a layer a of water-proof material such, for example, as tarred aper. Upon this we place a layer b of hair elt or other heat insulating materiah Upon this is preferably laid a thin wooden sheet or .board 0, and upon this a second sheet of water-proof paper d. A second layer of felt e is then preferably interposed between the paper 0 and the protecting covering 10 of sheet metal. Owing to this construction it will be observed that any moisture which may condense upon the under side of the sheet metal lining 10 of the bottom .of one of our improved compartments will work its -way downward along such inclined bottom,

flowing overv the water proof paper and finally escaping at the lower edge of the bottom and discliarging into the pan. Thus, the objectionable dripping, heretofore caused by sweating, is entirely eliminated.

It will thus be seen that we have provided a refrigerator wagon structure, the

parts of which can be readily removed for cleaning or repair, and which is simple in construction andv eflicient in operation, and it is thought that the many advantages thereof will be fully appreciated by those skilled in the art without further discussion.

What we claim is: 1. In a refrigerator wagon, the combination with the main frame comprising side sills, of a body compartment supported on said sills, a bottom for said compartment of a size capable of fitting between said sills, and cross-sills on which said bottom rests, said cross-sills being detachably connected at their ends to the under side of said sidesills, whereby, when said cross-sills are removed, said bottom can be lowered away from said compartment.

2. In a refrigerator wagon, the'combination with the main frame comprising side sills, of a body compartment supported on said sills, a bottom for said compartment of a size capable of fitting between said sills, and cross-sills on which said bottom rests, said cross-sillsbeing detachably consills, of a body compartment, a drip pan associated therewith, and arranged to catch the leakage therefrom, and cross-sills on ported by said sills and spaced apart, a

drip pan located between said compartments, and inclined bottoms for said compartments sloping toward said pan and having their edges overhanging the edges of said pan.

5. In a refrigerator wagon, the combination with the main frame including side sills, of a pair of body compartments supported by said sills and spaced apart, a drip pan locatedbetween said compartments, and

a drip spout communicating with each compartment, and discharginginto said pan.

6. In'a refrigerator wagon, the combination with a main frame, including side sills, of a pair of body compartments carried thereby,-and spaced apart, a pan located between said compartments, and arranged to catch the-drip therefrom, said pan being unattached" to said side sills, and crosssills on which said pan is wholly supported, whereby said pan may be lowered and removed without disturbing said compartments.

7. In a refrigerator wagon, a body compartment comprising sides and a bottom fitting therebetween, a sheet metal lining for said bottom having turned up edges, a sheet metal lining for said sides having its lower edge overlapping the upturned edges of said bottom, and means for so supporting said bottom that it may be lowered away from between the sides.

In testimony whereof we afiix our signatures, in presence of two witnesses.
