Speecation of Let-ters IPatent.

Patented March 16, 1909;

To all whom it may concern:

Be it known that 1, Jox-1N .1. HOFFMAN, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri,

5 have invented a certain new and useful lne provement in Outside (lar-Roofs, of which the following is a specification.

,My invention relates to outside car roofs and has for its principal objects to secure the sheets in such a Way as to minimize the destructive effects arising from the weaving 'ot the car and other changes from its normal shape. v

My invention consists in the construction and arrangements of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this spe'ciiication, and wherein like symbols refer to like parts whenever they occur, Figure 1 is a partial vertical cross section of a car roof embodying my invention, said section being taken on the line 1-1 of Fig. 3 Fig. 2 is an enlarged vertical cross sec tion of the middle portieri of the car roof on the line 2-2 of Fig. 3,1lig. 3 is a fragmentary longitudinal section and elevation of the ridge saddle and associated parts, Fig. L1 is a plan View of corner portions of sheets with a corner cap in position; lllig. 5 is a persimctive view of a corner cap g Fig. (i is a longitudiiml section of a corner cap on the line 6---6 of l? ig. 5; Fig 7 is an end elevation of a corner cap; Fig. 8 is 'a perspective view of the ridge saddle F ig. 9 is a cross section of the ridge saddle on the line 9--9 of Fig. 8; Fig. 1l) is a perspective view of one of the ridge saddle 'side stri is; Fig. 11 is a erspective view of one of t le supporting blocks for thc ridge saddle side stri is; Fig. 12 is a cross section of lock on the line 12---12 of 191g. 11; Fig. 13 is a perspective view of a roof sheet, Fig. 14- is an ond view of one form ol side'seam forthe roof sheets; Fig. 15 is a similar view of another form of side seam for the roof sheets; Fig. 16 is a cross section of the roofat the eaves showing a modiiied form ol' device for holding the metal sheets in place ;A

Fig'. 17 is a. cross section of the roof at the veaves showing a. inodiiied forni of device for 5 0 holding the metal sheets in place at the eaves; and, Fig. 1S is a detail elevation of the cli i used in thel device shown in llig.' 17.

y y roof comprises a wooden sheathing 1 and a covering of metal sheets 2 therefor.

l l i The sheets are connected at their sides by' standing seams or ribs 3 which run from the eaves toward the ridge. The sheets are arranged in two series thatextend the full length of the car, but the sheets of each series terminate short of the ridge thereby leaving a space between them. .The upper or ridge ends ot' the sheets have turned up or vertical 'flanges 4 thereon, and these flanges are reinforced .by bending the surplus metal at the corner of the sheet inwardly back of said flanges, without slitting the sheet.

As stated above, the sheets of one series do not interlock with the sheets of the other series, but the sheets of each series have side ilanges that interlock with each other. In order to hold the sheets at the ridge, suitable corner caps 5 are applied thereto. As usual with roofs of the type to which the present invention relates, the corner caps are made ol metal. These corner caps have transverse grooves t' arranged to receive the side seams or ribs and longitudinal grooves 7 adapted to receive the u )standing Hanges 4 at the ridge ends of the sheets. 'lhe grooves are of sufiicient width to prevent binding and to permit slight movement of the sheets. ln Order to prevent binding of the roof sheets against the roof, the midd e portion of the corner cap is provided with a distance piece S integral therewith which projects downwardly a little farther than the portions which interlock with the ridge. ilanges of the sheets. By this arrangnnont, the distance piece bears against the ridge pole 9, While the interlocking portions clear the. roof sheets. The corner cap is perforated to accommodate the fastening bolt hereinafter mentioned.

lllxtending longitudinally of the car at the ridge is la continuous wooden member 10 which constitutes` a ridge saddle and Whose underside. is shaped to conform to the' roof. 'lhe lower side of this ridge saddle has transverse grooves 11 therein arranged to receive the side seams oi the sheets and the transverse members of the corner caps which inclose said seams. lt also has a 'eontinuous longitudinal groo.y e. 12 which receives the ridge flanges of the sheetsand the longitu-- dinal members of the corner caps. llhe longitudinal groove is of such depth that therielge inoi'nber will rest on the corner caps, While the lower portions of the ridge saddle just clear the roof sheets; that is to say,the main weight of the ridge saddle is transmitted through the corner caps to the ridge pole instead of resting upon the roof sheets.

Theridge saddle is held in lace by means of bolts 13 which extend) downwardly through it and the perforations provided therefor in the corner caps and through the ridge pole. At each side of the ridge saddle is secured a longitudinal strip or stringer 14 by means of bolts 15 which extend transversely through said side strips and the ridge saddle. These side stri s are provided on their underside'with bloclis 16 which are grooved to fit over the side seams of the sheets. On the mounted run boards 17. Preferably', t e inner margin of the outer run boards rest on the ridge saddle. This construction gives considerable rigidity and relieves the roof sheets of considerable portion of the weight, and leaves the sheets free to move to a limited extent.

The lower end portions of the roof sheets are bent around and under the eaves and` then downwardly along the side of the car. In order to hold said downturned portion 19 Without binding, the fascia 2G is spaced from the side of the car by means of spacing blocks intervening between the side and. the fascia; and the fascia is mounted with its top portion slightly below the eaves. Preferably, the lower' downturned portion of the sheets has transverse corrugations 21 therein of sufficient width to bear against both the side of the car and the back of the fascia. Such corrugations stiffen the marginal portion of the sheets and o erate as friction members, which tend to ho d the sheets in position but yield when the stresses require it. It is preferable to make the recess back of the fascia wider than the distance between the top of the fascia and the eaves in order to prevent the sheets being pulled out of the recess. In some instances, it is desirable to use longer roof sheets and double back the outer portion thereof far enough for the endmost portion to rest on top of the wooden sheathing. The depending portion thus doubled back is corrugated and the double eorrugations afl'ord a greater resistance to the withdrawal of the roof sheets from the recess and increase the tendency of the sheets to resume their normal positions. In like manner, flexible strips 22 corrugated transversely may be secured to the wooden sheathing and have their free ends bear downwardly against the curved end portions of the roof sheets, whereby said strips tend to maintain said roof sheets in their proper normal positions in the recess.

Instead of having the fascia spaced from the side of the ear, it is practicable to use the construction illustrated in Fig. 17. As illustrated in this ligure, the upper portion of the fascia is thinner than the lower portion and the top thereof is at a distance below' the eaves. Mounted upon the upper thin Vportion of the fascia are a series of clips 23 which extend above the top of the fascia and are bent Vinwardly above the same. The roof sheets are bent around and under the eaves and thence rebent under the clips. As before stated, the ends of the roof sheets may be crimped or corrugated transversely.

Obviously, my device admits of considerable variation without departing from my invention, and therefore I do not wish to be limited to the specific construction shown and described.
