WALTER P. MURPHY, OF CHICAGO, ILLINOIS.

CAR-ROOF.

Applieation filed January 29, 1919.

T0 all whom it may erinnern.'

lie it known that il, lavan l. Monenr, a` citizen of the United States. residing at Chicago, count)Y of Cook, and State of Illinois, have invented certain new and useful Improvements in Car-Roofs, of which the Jfollowing is a,deseription.

In the drawing:

Figure l is an enlarged detaill transverse sectional view of a car roof taken on the line i-i Fig. 2.

Fig. L), is a detail top plan view of a ear roof embodying my invention.

Fig. P5 is an enlarged detail sectional view on the line 3 2 Vig. L.

Fig. 4 is an enlarged detail sectional View showing the flexible joint between roof sheet and the eaves flashing.

Fig. is a detailed plan view of a` car roof illustrating another embodiment of' my invention,

The object of my invention is to provide, for securing the roofsheets in operative position on the ear and free to more about to a limited extent.

The invention consists in positioning the roof sheets and holding them down upon the roof' Vsubstrluture b v means at the marginal edges of the root' sheets and leare the sheets free to move about within certain limitations,

mount the roof sheets that they may move 'as if on a pivot at their ridge ends.

A further ohject'of' my invention is to proride a construction at the ridge whereby the roof sheets may7 pivot on their ridge corners.

Further objects and particulars of the invention will appear from the following description of the roof construction shown in the iweoinpanying drawings.

The reference numeral 1 designates a suitable roof sheathing of a car. i

The roof plates or sheets 2 are connected at their eaves end to a` fiashing 3, the 'joint between the fiashing and the roof sheets being a loose fiexilole joint as shown, in detail in Fig. 4.

The side marginaledges of the roof sheets are provided with upwardly1 standing rebent flanges 4 which interlock with-a seam cap 5. Between the marginal flanges t of the roof' sheets I position a mullion 6 which is suitably secured to the roof sheathing, threbeing a space between the side niarginal flanges 4 and the mullion whereby the Specification of Letters Patent.

sheets are free to more with respect `to said mullion.

The ridge end of the roof plate or sheet is provided with an open re-bend (it which overlies the upper face of the roof' plate and is adapted to receive a filled strip 7 which is suitably secured therein and extends approximately the width of the sheet or plate. As will be seen from the d awing the wood filler or strip extends beyond the free edge of' the bend (L the object of which will be hereinafter stated.

A ridge cap S is provided with down wardly extending side 'flanges 9 which terminate at the bottom in an outwuirdlr extending flange lll which flange l() overlies the roof' sheet or plate 2. It will be seen that the ridge, ends of the root' plates. on opposite sides oi' the ridge` are normall;v spaeed from each other under the ridge cap` while wood filler strip 7. carried b v the roof plates is in contact with the side flanges 9 of' the ridge capv The wood filler strip T extends bevond the free edge of the bend (i of the plate 2 so that the edge of the bend 6 is prevented from eenling into contact with the side flanges El of the ridge cap, thereblveliminating the possibilities of said edge cutting through the ridge cap. This is ot importance bei-anse the roof sheets or plates are prevented from moving bodilyY toward the eaves of the car b v reason of the filler strip T abutting the side flange ofthe ridge cap` besides which the roof sheets or plates.I being free at its marginal edges to more to compensate for service movement of the ear, without injuriY to the. Sheets or plates`r and in such movements said plates frequently pivot on its ridge corners said corners being fulcrumed on the side ianges of the ridge cap and as the wood fillenstrip 7 contacts with the flange of the ridge cap.` there is no danger of the ridge cap becoming worn or eut b v such pivotal action of the root plate.

Therunning hoard saddle l1 has a recess 12 of a size to receive the ridge cap as shown 4in Fig. 1. the side walls of the recess approximately fitting against the outer face of the side flanges 9 of the ridge Cap. wherel the said side flanges are sustainedy against stress in a direction toward the eaves of the car. A

All joints between the parts at the eaves, roofs seams, and ridge are weather proof.

The wood filler strip 7 constitutes a rigidifyng element acrossthe ridge end of the roof sheet or plate which stitfens and` reinforces the ridge end' and prevents the ridge end of the plate from buckling or being distorted by stresses incident to the .service movements of the car and roof so that there is very little, if any, likelihood of the roof plate becoming jammed at the ridge, therefore the joint between the ridge ap and the rootI plate is always maintained normal, whereby the slipping action at said joint is always free.

In Fig. 5 the construction is substantially like that heretofore described, the only exception being that the filler strip 7a is convex on its eaves edge whereby the roof plates rocks on said convex edge instead of pivoting on its corners as described in connection in Figs. 1, 2, and 4. In this construction it will be seen that there is a running hoard saddle l1 positioned opposite the apex of the convex edge of the liller strip T.

From the above it will be seen that in the construction shown in Figs. l, 2 and 4, the roof plates are movably mounted on the substructure and spaced apart at the ridge and at the side marginal edges, and have a free loose flexible connection with the flashing at the eaves, and Iare free to pivot at their ridge corners to compensate for service movement; while in Fig. o the Construction is the same with the exception that the filler strip is convex .on its eaves side, whereby the sheet or roof plates pivot at a point between their side marginal edges at their ridge ends.

The abutment of the filler strip on the ridge end of the sheet or plates is the sole means of restraining bodily movement of the roof plates toward the eaves of the car.

Matter shown but not claimed herein is claimed in my application, filed January 29, 19191* Serial No. 273,824.

(3. In a car, a root including plates, and a ridge cap, a rigidifying element on the ridge end of the plates freely confined under said cap and constituting an abutment to restrain the plates against movement toward the ea ves, but leaving the plates free to move in the plane ol` the roof as it ou a pivot.
