Application fled October-27, 1921. Serial No. 510,967.
This invention relates to improvements in freight car all metal roofs and more particularly-to roofs of this character of the ventilated type such as described in my former Patent No. 1,300,258, of April 15., 1919.\ Unless the metal surface on the underside of a roof of this character is covered with an insulation or lining it will sweat and the condensation drop down upon. the lading.
The placing of alini'ng" or insulation under,
the roof is an additional expense. However, this is obviated by arranging air ducts 'or ports along the edges of the roof which tend to equalize the temperature on both .sides and which will reduce or do away with the sweating. My former patent above referred to accomplishes this by striking up a rib adjacent each transverse edge of each roof sheet which ribs interlock to hold the roof.
sheets together and the edges at the side together with the upstanding ribs resting on the top of the car side plates, extended therebeyond and are bent down over the side sheathing which allows the-passage of air through the ribs but prevents water from entering or blowing into the interior of the car.' It is an object of this invention to simplify the construction of a roof of this character and reduce the cost of fabrication by terminating each rib of the roof sheet just before the side edges are bent down over the car side plates and applying in lieu of the integral bent over rib a metal plate pressed to correspond thereto which will continue the passageway to the ends of the side edges of the 'sheets.
While the preferred form of this invention is il'lustratedupon the acbompanying sheets of drawings, yet it is to be understood that minor detail changes may be made without spective of Fig. 2 illustrating one method of applying the ventilation'cap. i
Fig. 4 is a similar view illustrating anoth er method.

fication.
As shown in the drawings the roof sheets extend transversely across the car and rest upon the side plates 11, the struck-up rib 2 of roof sheet 3 lays over and receives. the
rib 4 of roof sheet 5 with the flange 6 of rib and maybe attached thereto by bolts'pass- -ing through both sheathing and side plate but the struck-up ribs 2 and 4 are termi- I nated at the bend. To allow air to pass through the ports or ducts formed by the.
struck-up ribs a ventilation cap is provided, preferably pressed from a metal plate, having a body 8 with a central struck-up rib 9 extending throughout of such dimensions as to be received within the struck-up ribs of theroof sheets and to form an extension thereof to provide an air duct or port opening to the atmosphere at the edge of the roof sheets below the to of the side sheathing, and with the top 0 both body and rib bent to rest on top of the side plate and against the exterior of the side sheathing of the car.
The ventilation cap 8 may be applied under both roof sheets and rest upon the side plate, as shown in Fig. 3, and the bolts securing the roof sheet flanges may pass through the capbody or it may be inserted between the roof sheets, as shown in Fig. 4, or as shown in Fig. 5. The rib :10 of the cap may be of such dimensions as to lay over and embrace the outer roof sheet rib 2 with the body 11 extending to lay over the roof sheets and preferably tapered-from the bend at the top of the car side to the upper extremity of the rib 10.
The same idea'is carried out in a roof in which the struck-up rib 12' of the roof sheet is reduced in height and tapered tomerge into the margin of the roof sheet at the bend over the exterior of the car side, as shown in Fig. 6, and by gaining out the sheathing 7 directly under the end of the rib l2 and placing therein beneath and extending below the end of the roof sheet a ventilation cap 13 in the form of a plate having a depressed ortion 14 fitted into the gained out sheathing which forms an air duct or port opening into the atmosphere below the roof sheet.
below the edge of the roof to the interior of the car by the way of the interior of the roof sheet ribs.
What I claim is A ventilated car roof comprising metal roof sheets resting upon and bent down over the car side plates having transverse interlocking struck-11p ribs between the bends o. the roof sheets with the metal of each sheet extending in the same plane on the opposite sides of each rib adjacent to and on each side of each bend and the metal of each sheet cut away from the end of each rib and the end of the sheet, closure plates each having a continuous struck-up rib adapted to be received within the interlocking ribs of each pair of adjacent roof sheets, said plates and struck-up ribs resting upon and bent down over the car side plate under said interlocking ribs and roof sheets with the plate rib extending between the cut-away portions of the roof sheets adjacent their ends.
