This side plate is shown as of a Z-bar crosssectiomthe bolts being secured tothe upwardly extending angefE thereof. The kportions B of the roofing sheets and also the reinforcement C thereof are'provided with vertical slotslF which register with the bolts D, said slots terminating at their upper ends `-in circular enlargements F, which latter are adapted to receive securing members sleeved on the bolt's. As shown in Figures 4 and 5, the securing vmembers are collars Ghaving anges G' for engaging the circularportions F. and surrounding portions G2 4Claims.
The invention .relates to railwaycars such as refrigerator. cars which are :provided Ywith thermal insulation for the walls and roof thereof. More particularly vthe invention relates .tothe means 5 forinsulatingthe roof kor ceiling of the car, and has for its object facilitating the Yinstallation of such insulation and :protecting itk from injury during service.
In the presentstate ofthe rart yit is usual to support the ceilinginsulation from the roof or roof frame. This requires the installation of the insulation subsequentto theplacing of the frame onthe car and Ywithcertaintypes of roof, where the frame or. supporting trusses areintegral with l5 the roofing sheets,.the placing of the insulation forbearing 1113011 hPOfOn B-y Nllt'S Hengagis rendered difcult. It is, therefore, one of the ing the bOltS'D are then used 'OI' Clamping 1211 objects of my inventionfto obtain a construction members G in DOSOIL In the mOdedrCOnin which the supporting f of :the ceiling insulation struction showniniFigures 6 and 'lin place of the is entirely independent of the roof or lits frame. nut H, the bOl D' has Placed theleOn a SleeVB I With this -andfother objects Iinview, theinvenhavinga head I at its outer end and a collar I2 which is slidable on the sleeve into androut of engagement with an aperture H. The outer end of the bolt is then riveted to permanently secure the sleeve I, and a U-shaped wedge member. J is inserted between thehead I and the collar I2. Thus this wedge member servesto hold the collar in locking engagement .with the circular recess Fvand also to clamp the portion Bto the side plate E.
A car roof constructed asabove described can bereadily .attached to or detached from .the frame ofia car 4.which .facilitates the ,original placing and the repair of the ceiling insulation.
The ceiling insulation is supported entirely independent of the roof structure through the medium of a series of cross members attached at their opposite end to the side plates E of the car frame. As shown, bracket members K are Welded or otherwise secured to the side plates E to project inward therefrom and to these are secured the ends of metallic cross members L, preferably of inverted channel cross section with laterally extending foot flanges L. Within the channels are placed wooden ller strips M which extend downward some distance below the flanges L and are secured by bolts M. To the strips M is secured a ceiling N, preferably formed of match boards and with a liner panel N slightly 'spaced from the boards by strips N2. These parts may be nailed or otherwise secured to said strips M. A layer of insulating material O, preferably hair felt, is then placed in the spaces between the strips M, and is marginally secured by strips P. 'I'hese strips are placed beneath t'he flanges L' of the members L compressing the marginal portion consists in the construction as hereinafter set forth. Y
In the drawings: s VFigure 1 is a. crosssection through one-half` of the;roof portion of a railway car provided with my Yimproved insulating means;
Figure 2 is a longitudinal section;
VFigure'B isa plan View Awith one-'half Vof the roof removed to show the underfra'mefor supporting the insulation;
Figure 4 isa crosssectionfillustrating the detachable connection between the roof and the car and also the support for the insulation;
Figure 5 is a side elevation of Figure 4;
Figures 6 and 7 are views similar to Figures 4 and 5 illustrating a modified construction.
My improved ceiling insulation may be applied to cars having any desired type of roof covering, but as specificially illustrated the roof is of the so-called two-plane type. In this, the use of separate carlines is dispensed with and the roof trusses are formed as an integral part of the weatherproong roong sheets. In detail, A are the roof units comprising sheets extending from 45 eaves to eaves with a central upper plane portion A and lower plane portions A2 on opposite sides thereof and intermediate substantially vertical portions A3. The edges of adjacent sheets are welded or otherwise secured to each other as 50 indicated at A4. At the eaves both upper plane and lower plane portions are turned downward to merge into a single vertical plane portion B, preferably reinforced by a parallel member G. To permit of readily attaching and detaching the roof from the car frame, it is secured thereto by tions of the felt and securely holding the same from displacement. A second layer of felt O is then placed above the layer O and is carried over the members L. This is secured by cap members Q which may be clamped by upward extensions of the bolts M. Thus as shown the threaded ends of these bolts M have nuts M2 thereon for clamping the strips M to the members L, and nuts M3 for clamping the caps Q upon the felt layer O'.
At the sides of the car the ceiling N engages mortised wooden strips R Which are attached to and supported from the brackets K by means of bolts R. These strips R also form the means for securing the insulation for the sides of the car which, however, forms no partl of the present invention.
Where the car is provided with a hatch opening the hatch frame S may be placed between a pair of cross members L and secured thereto by angle brackets S'. As shown, the angle brackets S are attached to the members L by the bolts M and to the frame S by bolts S2. The insulation O is carried upward along the side of the frame S and is clamped at its upper end by a strip S3.
The ceiling insulation constructed as above described is entirely independent of the roof and may be placed in position before the roof is attached to the car frame. Furthermore, by reason of the quick detachment connections between the roof and the frame, the former is easily removed at any time should it be necessary to repair the insulation. The insulation and its supports are also freed from any roof stresses.
What I claim as my invention is:
l. In a car having metallic side plates and a roof removably supported thereon, of angle brackets rigidly attached to and projecting inward from said side plates, metallic channel bars secured to said angle brackets and extending transversely of the car between the opposite side plates thereof, Wooden strips secured in the channels of said bars and extending below the same, a ceiling secured to the underside of said strips, a layer of insulating material extending between adjacent strips and marginally secured thereto, and a second layer of insulating material extending over said rst layer and said channel bars and clamped to the latter.
2. In a car having side plates and a roof removably supported thereon, inverted channel bars connected to and extending between said side plates and independent of said roof, said `bars having foot anges on opposite sides there- 0f, wooden filler strips engaging the channels of said bars and projecting below the same, a ceiling secured to the underside of said filler strips, insulating material arranged between adjacent strips, strips placed beneath said foot flanges and engaging the marginal portions of said insulating material to clamp the same, a second layer of insulating material extending over the first layer thereof and also over said channel bars, and caps for clamping said second layer of insulating material to said channel bars.
3. In a car roof having side plates and a roof removably supported thereon, inverted channel bars connected to and extending between said side plates independent of said roof, said bars having foot flanges on opposite sids thereof, a wooden filler strip engaging the channels of said bars and projecting below the same, bolts for securing said filler strip to said channel bars, a ceiling secured to the underside of said ller strips, insulating material arranged between adjacent strips, strips placed beneath said foot anges and engaging the marginal portions of said insulating material to clamp the same, a second layer of insulating material extending over the rst layer thereof and also over said channel bars, caps for clamping said second f layer of insulating material to said channel bars, upward extensions of said bolts passing through said caps, and nuts engaging said upward extensions for clamping said caps in position.
4. In a car, the combination with the side plates thereof, of a roof having means for quick attachment to and detachment from said side plates, comprising depending eaves flanges overlapping said side plates, said flanges having apertures therein With entrance slots to said apertures from the lower edge of the flange, bolts projecting laterally from said side plates registering with said apertures and adapted to enter the same through said slots, fasteners sleeved on said bolts engaging said apertures, and clamping means for said fasteners; a ceiling supported from said side plates independent of said roof and an insulating means supported by said ceiling accessible upon the removal of said roof.
