LUTHER I1. YATES, OP SAN FRANCISCO, CALIFORNIA CALIFORNIA, ASSIGNOR OF ONE-HALF TO REFRIGERATOR CAB This invention relates to a refrigerator car, and especially to a type of car that ut1- lizes a metal bulkhead structure between the cargo compartment and the ice compartment.

It is now common to provide a bulkhead between these two compartments, and constructed in such a way as to be substantially secure against pilfering by anyone who; may gain access to the ice compartment. This 11 pilfer-proof feature is desirable, because often valuable non-perishable cargo is shipped in the cargo compartment, the ice compartment being empty.

It is one of the objects of my invention to to improve in general this type of refrigerator car.

It is another object of my invention to provide an improved form of bulkhead between the two com artments, that is very strong and rigid. accomplish this result by an arch truss construction.

It is another object of my inventlon toprovide a novel and improved form of ice grate in the ice compartment.

My invention possesses many other advantages, and has other objects which may be made more easily apparent from a consideration of several embodiments of my invention. For this purpose I have shown a few forms in the drawings accompanying and. forming part of the present specification. I shall now proceed to describe these forms in detail, which illustrate the general principles of my invention; but it is to be understood that this detailed description is not to be taken in a limiting sense, since the scope of my invention is best defined by the append ed claims.

Referring first to Figs. 1 to 5, the refrigerator car therein shown is indicated as having the usual floor, wall and roof construction. ,Since my-invention does'not particu- 8e larl relate to this construction, I shall descri e these parts only in a general fashion.

As shown in Fig. 1, the car has a engitudinal beam 11, and a number of transverse beams 12. Above beams 12 rest the floor 90 joists 13, and the end beams 14. At each sider of the car there is a transverse beam 15 (Fig. 2). Above beams or joists 13 is disposed alayer of tongue and groove board 16. Several insulation layers indicated at 17 can be disposed over this board, and on top, there can be provided the transverse tongueiand groove flooring proper 18, which covers the cargo compartment. The walls of the car similar to Fig.

can be formed'similarly. There are a npmbar of layers of insulation, in this wall structure, separated b air spaces, as indicated enerally at 19. he outer surface is formed y a layer of tongue and .groove wood 20, and the inner surface by tongue and groove boards 21. The ceiling 22 is also formed. by similar boards; and the roof is formed of layers of heat insulation such as 23. Hatches 24 are formed over the ice compartments, closed as indicated in Fig. l, by the covers 25. Underneath each ice compartment, drains 26 are provided, protected by a screen guard 27. i

The bottom of the ice compartment is formed by the aid of a metal pan 28. This pan has an edge 29 overlying the sill formed by the adjacent end of the cargo compartthe aid of the angle strip 46'and bolts 47.

ment flooring 18 (Fig. 2). It also has sides 30 (Fig. 1) and a rear. portion 31 (Fig. 2) that is overlappled by an angle piece 32 extending over t e transverse sill beam 33. The end and sides of the ice compartment are formed by a metal layer 34.

To provide the bulkhead framework between the cargo compartment 35 and the ice compartment 36, I use a series of vertical structural columns. In the present instance, I-show pairs of spaced angle irons 37, 38 forming the intermediate columns. Each of these angle irons has an angle presenting a vertical flat face toward the cargo compartment 35, as shown at 39, Fig. 1. The end columns are formed by single angles 40.

The bases of each of these angle irons are fastened to foot pieces 41 as shown in Fig. 2. These foot pieces extend over the edge 29 of pan 28 and down into it, being securely anchored thereto. n

Sections 41 of perforated sheet metal form one surface of the ice compartment 36.

These sections formhalf arches arranged verticall the point of the arch being near the roof of t e car. These sections each have side flanges 42, as shown most clearly in Fig. 3. These flanges near the top of the arch, can

be accommodated between the flanges of the angle irons 37, 38 which form the intermediate columns. The spacing of these angle iron flanges is such that the flanges of ad acent sections 41 can be placed between them, as indicated in Fig. 3, and yet leave a central space for filler plates 43. The adjacent flanges of adjacent sections are clamped together to form a very rigid and strong structure. The end columns 40 engage the outer flanges 42 of the end sections 41. Strips 44 similar to the filler strips 43, engage the outer surfaces of these outermost flanges 42.

. As shown most clearly in Fig. 2, each of the sections 42 also has a horizontal flange 45, which is fastened to the ceiling 22, as by This angle strip 46 extends entirely across the car and is fastened to the top of each section 41.

of struts, such as the plates 48, 49, 50 and 51. These plates engage between the flanges of the adjacent sections 41", and also are accommodated in the space between the angles 37 and 38. They correspond in position to thefiller plates 43 at the top portion of the structure while the flanges 42 are directl accommodated between the angles 37 an 38. Similar strut plates are also provided ad acent the end columns 40, corresponding to the position of the filler plates 44 at the top of the arch.

The bottom or end of the arch is formed and supported in a manner most clearly indicated in Figs. 4 and 5. In these figures the sections 41' are shown as having turned up edges 42 resting on foot supports 53, fastened in the corner of the car. These supports are provided with a pair of spaced ears 54 accommodating the flanges 42, as well as the central bottom stiffener plate or strut 51. These latter bottom stifiener fastened between the flanges o the horizontal angle Il'OIlS 55, extending between the vertical columns and the supports 53. The vertical flanges 56 of these angle irons are fastened between the ears 54, as shown clearly in Fig. 5. Bolts 57 serve to hold this part ofthe structure together. The horizontal flanges of the angles 55 are cut away for a length sufiicient to permit the vertical flanges 56' to enter between ears 54. Furthermore, each foot member 53 has an angle flange 58 that is arranged to rest over the parts 31, 32 and the cross beam 33. As'indicated in Fig. 1, the end foot pieces 59 are narrower than the intermediate foot pieces 53, since they accommodate the end stiffener angles and struts for-the arch.

In order to form a complete basket for the ice compartment 36, I provide a screen 60. This screen, as indicated most clearly in Fig. 3, can be fastened to the upright side posts 61 and can be disposed to form the end of the ice compartment, as well as the two sides, the bottom and the inner sides being formed by the sections 41. Cross bars 62 are arranged in spaced relation along the bottom of the sections 42 to form grate bars, and to protect the arch when ice is dropped into compartment 36. They can be formed of sheet metal with a central ridge (Fig. 2).

In order to provide a vertical surface between the ice compartment 36 and the cargo compartment 35, I provide an insulation pad 63 supported on the columns 37, 38, and 40.

This pad can be formed in any usual manner.

lates are also lation is facilitated into and out of the com partments and 36. The upper opening can be provided with a screen grill 64. The slower opening can be provided with a horizontal beam 65 in order to prevent cargo from sliding out of the compartment 35 underneath the sections 41. This pad is provided at its top and bottom edges with metal parts 109, 110. These each have flanges through which bolts 111 can pass to fasten the pad to the columns in a simple and ready manner.

An alternate mode in which the insulation pad 63 can be fastened to the vertical columns is shown most clearly in Fig. 15. Two modifications of this fastening means is indicated in this figure. A T bolt 66 can be arranged to engage the inner edges of the angles 37, 38 and to pass between them and through pad 63. Alternatively, a bolt 67 having a U shaped head could be used to engage over the vertical flange of one of the angle irons 37 or 38.

In the form illustrated in Figs. 1 to 5, in-

' elusive, the arch sections 41 are provided with uniformly-spaced perforations. However, other types of perforations could be used; one modification is shown in Fig. 13.

In this figure, at the bottom of the section 68, there are elongated apertures 69, whereas in the other portions of the section 68 smaller round apertures 70 are indicated. The character and disposition of these apertures can be varied to suit the individual requirements; they may be square or oblong, uniformly or irregularly spaced.

It is also possible to vary the character of the ice grate bars 62 indicated in the first five figures. A few examples of various forms of bars are shown in Figs. 10, 11, and 12.

In Fig. 10, the grate bars 71 are shown as T sections, the horizontal flanges of which are shown as riveted or otherwise fastened to the sections 41.

In Fig. 11, I show transverse wood bars 72 fastened'to the sections 41, as b bolts 73.

In Fig. 12, the grate bars are ormed by channel bars 74 appropriately fastened to the sections 41.

In Figs. 16 to 23, I indicate the various forms of the arch sections that can be used, as well as of the struts and columns supporting them. For example, in Fig. 16, the sections are shown as formed by the flanged sheet metal pieces 75 fastened at the edges to angle irons 76. The adjacent flanges of the angle irons are arranged to encompass the strut members such as 77. In Fig. 17, the sections 41 are the same in shape as those in Figs. 1, 2, and 3. However, the column structure differs, as in this form only one angle iron 78 is .utilized for each column, and

the struts, such as 79, are formed with flanges 80. These flanges 80 are intended to contact with the insulation pad 63.

In Fig. 18, the sup orting columns are formed by thechannel ars 81. In'Fig. 19, the columns are shown as formed by I beams 82, and the arch sections are simply flat sheet metal pieces 83 fastened to the inner flange of the I beam 82.

Fig. 20 shows the form that was indicated in Figs. 1 to 3 inclusive on an enlarged scale, and further explanation thereof is unnecessary.

In F ig. 21 the arch, instead of being made 'in sections, is made of a continuous sheet of metal 84 supported appropriately on a column and strut structure of any convenient form.

In Fig. 22 the sections 41- are shown as having their flanges 42 abutting and supported by the struts 86 fastened to the columns.

Fig. 23 shows a form somewhat similar to Fig. 22. The strut 87 is shown as being supported on the central flange of the T column 88. Furthermore, the abuttin flanges 42 of the sections are encompassed y sheet metal pieces 89 of U section, holding them to gether.

In the forms so far described, the arch sections provide rigidity to the bulkhead and prevent any breaking down of the bulkhead even upon the imposition of a great horizontal force against the cargo compartment. The same principle of arch design can be incorporated in a horizontal arch, and one form of this construction is shown in Figs. 6, 7, and 8.

So far as the car structure is concerned there is no material difference between it and the form shown in Figs. '1, 2, and'3. The

vertical columns can be formed as before by standard structural pieces, such as angle irons 90, 91, and 92. On the cargo side of these columns an insulation pad 93 can be supported. The arch sections 94 are shown as made from a perforated sheet metal, having horizontal flanges-95. These sections are placed one on top of another in a vertical series, as indicated most clearly in Fig. 8. They are held to the vertical columns by a series of braces such as 96, 97, 98. Each of these braces has a vertical portion held between the angle irons 91, 92, and horizontal portions engaging the flanges 95. The ends of the arch abut the vertical columns formed by angles 99, fastened as by bolts 100 to the walls of the car. The top section 94 has its horizontal flange 95 fastened directly to the ceiling 22. The lowermost section 94 has its bottom flange resting on "a foot member 101 similar to the foot members 41 of the first form. The ice compartment 102 is formed by these sections 94 and the screen 103, which extends, as shown in Fig. 7, along one end of the car and along the sides as far as the vertical columns 99. This screen 103 thus forms a basket for the accommodation of the ice.

The ice grate proper is shown in Fig. 14. It comprises a corrugated and perforated metal plate 104 having a contour that permits it to be accommodated between the mesh screen 103 and the sections 94. It is intended to rest upon the angle iron frame 105 located at the bottom of the ice compartment. As indicated in Fig. 9, however, the screen 104 can be accommodated by the channel irons 106 which replace the angles 105.

'In this form also, it is seen that a rigid arch construction is interposed between the ice compartment 102 and the cargo compartment 107. The ice is well supported in the compartment on the grate 104. In other respects, this form of the invention is similar to that already described; thus a metal lining 108 is used at the bottom and sides of that ortion of the car, which accommodates the ice compartment.
