ANCHOR FOR ROOF-SHEETS.

Specification of Letters Patent.

Patented May 22, 1917.

' Application filed October 21, 1916. Serial No. 126,842.

To all whom itm'ag concern:

Be it known that 1, JOHN T. CRALLEY, a citizen ofthe United States, and a resident of the city of Chicago, in the county of Cook 5 and State of Illinois, have invented a new and useful Improvement in Anchors for Roof-Sheets, of which the followingis a specification.

roofs for railway cars of the type which'has roof sheets pivotally secured in place, andis an improvement on the ridge construction shown and describedin C. G. Murphy Patent No. 1,133,493, dated March 30, 1915.

The objects of the invention are to provide for securing the roof sheets inplace so that they are free to move about to a limited extent, and to locate the securing means heneath the roof sheets instead of on top of them. I

The invention consists in positioning the roof sheets and holding them down upon the roof substructure at the ridge by means of anchors which are pivoted to the substructure at the ridge line, and which fit under the ends of the roof sheets and are hooked over their ridge flanges. There is a separate anchor for each roof sheet, thereby permitting the roof sheets to move independ- Further objects and particulars of the in vention appear in connection with the following description of the roof construction shown in the accompanying drawings; and

I what the invention consists in is further stated in the appended claims.

y In the drawings, wherein the same refer ence characters designate the same parts in the several views,

Figure 1 is a plan view of a ridge portion ofan outside metal car roof, showing the pivots and anchors for securing two roof sheets; I

I Fig. 2 is a cross-section of the same on the line 2-2 in Fig. ,1; and

Fig. 3 is a perspective view of a pair of roof sheet anchors in place on the substructure ready to receive the roof sheets.

For purpose of illustration, the invention is shown applied to a car having a wooden ridge pole 11 and roof sheathing boards 12. The roof sheets 13 have pivot bosses ,14'

- "This invention relates to outside metal ently of each other'upon the substructure struclr up-in them near their ridge ends, and

upstanding flanges 15 along their ridge ends. The edges of the flanges 15 are bent in and. turned, down over the roof sheets The roof sheets are spaced apart at their ridgeends and the flanges 15 are covered by an inverted channel shape ridge cap 16,

which, has the lower edges of its side walls bent in and turned up under the inturned extremities of the roof sheet flanges 15. r

The roof sheets are loosely held in place by anchor strips 17, which are arranged in pairs, one on each side of the ridge,.with

their ridge ends lapping and pivotally secured to the substructure by means of a bolt,

18. Each-anchor strip has a pivot boss 19 fitting under the pivot boss 14; in the corresponding roof sheet, and an. upstanding flange 20 at its ridge end which is bent at its extremity over the flange 15 of the roof sheet to hold the roof sheet down on the anchor strip. This arrangement permits the roof sheets to pivot around the pivot bosses, and permits the anchor strips to pivot around the bolts 18.

The invention is not restricted to the particular shape and arrangement-attire roof sheet pivot bosses, flanges and anchor strips shown in the drawings.

' I claim the following as my invention:

1. An anchor strip for pivotally securing a roof sheet, said anchor strip having'a pivot for the roof sheet to turn on and said anchor strip also having means formed integral therewith for securing said anchor strip to the roof sheet.

2. An anchor strip for pivotally securing a roof sheet, said anchor strip having a pivot for the roof sheet to turn on and a flange adapted to hook over the edge of the roof sheet for securing said anchor strip to the roof sheet.

3. An anchor strip for pivotally securing a roof sheet, said anchor strip having a pivot boss formed up 1n 1t for the roof sheet to turn on and means at one edge for hooking over the edge of the roof sheet forholding a roof sheet, said anchor strip having a pivot for the roof sheet to turn on, in combination with means for pivotally securing said an chor strip to the car, and means for securing said anchor strip to the roof sheets, said se: curing means being located'at the ridge of the car, and a ridge cap for covering said securing means.

6. In combination with movably supporh ed roof sheets having pivot bosses near their 10 ridge ends. a pair of anchor strips lapping at their ridge ends and pivotally seeiired to the car through their lapping portions, said anchor strips having pivot bosses fitting the pivot bosses of said roof sheets.

Signed at Toledo, Ohio, this 17th day of October, 1916.
