To. all @cham t may concern:

Beit known thatI, VALTnn P. MURPHY,

body setting up stresses tending to tear the sheets, which stresses, are concentrated at the points where the sheets are held down on the roof substructure, and in part to the greater liability of the sheets to rust out under the clips on account of the constant frictionbetween the clip and sheet due to straining of the car, and the presenceof moisture and grit under the clip.

My invention consists yin the provision of an improved means for attaching thesections of'a sheet metal covering of a car roof. to the car structure, whereby there is obtained great freedom of movement of the sections with respect to the substructure and the rusting out of the sheets under or near the attaching means is overcome, and inV the l particular construction, arrangement andv combination of the various parts whereby this. isl accomplished, as more fully hereinafter described and particularlypointed out in the claims.4

For the purpose of more fully illustrating -my invention I have appended the accompanying drawings, wherein like symbols are used to designate like parts wherever they occur.

In the drawings Figurel l'is a partial section through the eaves of a car transverse to the longitudinal axis thereof; Fig. 2'is a side elevation of my f improved roof clip; Fig. 8 isa front elevation of the same, and Fig. 4: is a section through .the clip on' the line 4-4 of Fig. 2, showing a seaml in section arranged therein.

In the drawings 5 is'the side plate 'of .a car, 6 the side sheathing, the fascia, 8 the roof sheathing, 9 and 10 the metal roof sheets connected by the upstanding seam 22,

1,1 a hood clip forcovering the ends of the 55 vseam connecting, the roof sheets and securing the sheets loosely upon the roof substructure,

12a bolt for securing the cIip4 to the fascia, and 13 is a nail to provide additional securing means for the clip. The clip itself comprises a base-portion 14 provided with a hole '15 for `the nail and a square holef16I for the bolt and connected to the hood portion 17 by yokes'or straps 18 which yoke portions are spaced away from the under face of the base.-

portionsothat when the clip is applied to the car a spaceis left between the fascia and the yoke portions, into which space the turned down ends 19,01? the r'oof'sheet's eX- tend and in which they can have a limited amount of play. The hood portion 17 has at the lower edges of its side faces-curved or dished flanges E20, which lflanges have eX- tensions 21 projected beyond the open side 'of the hood.4 The inner ends of these ,extensions 21 are spaced so far from the point of attachment of--the clip tothe fascia that in case the angle between theside and roof of the car becomes more obtuse through any cause and there is any tendency for the inner ends 'of the flanges to be jammed downv on the roof sheets, the result will be the bending of the clip at the yoke portions 18 rather than the clamping 'of the roof sheets, due to the long leverage of the extremities of the flanges with respect tothe point of attach- 4ment of the-clip.A These flanges on account of their arrangement and peculiar 'conformation not only present a broad under surface free `from sharp edges and so unlikely to cut the roof sheets but are spaced sufhciently. far apart so that in case'there is any tendency` for kthe clip, either through accident, or careless workmanship-'in its .application to the car, to turn upon the bolt 12, which would resultin bindingthe roof sheet under one of the flanges, this tendency is largely overcome, and the likelihood of the roof sheet ,becomingy clamped from movement on the substructure is much less than where the older type of clip is used. More- 'over the wide spacing apart of the flanges 'enables a space of 'at least the width of the seam to lbe left between the inner faces of Iqo.

the hood and the seam onl either side thus" f providing adequate. room for movement of the roof sections longitudinally on the substructure. The spacing 'of the yokes 18 away .from the side of the car not only enables the turnedl down edges of theroof sheets to have free play over the eaves, but

-enables the -front end of the hood lto be closed by the vfront side wall 23 to prevent the weather from blowing into the open end of the seam," while anydirt or-water collecting beneath the hood portion can readily escape -through the 4openin 24 below the front wall. Moreover the ront wall '28l is spaced away from the end of the seam, thus allowing the roof sheets considerable movelongitudinal axis of the car.

In applying the roof-clip to the ment onthe substructuretrans'verse to the` car roof,

the workman, @after positioning the roof sheets upon the substructure,places the clip centrally over the seam and marks the place for the bolt 12, then removes the clip and bores a hole through the fascia, side sheath-4 ing and side plate forthebolt. The. clip is then replaced in position and the bolt 12 is inserted and made fast. The nail 13 is -then 'driven as an additional securing means. This method ofapplying the clip insures that the lianges 20 shall be spaced slightly above lthe roof sheets, and shall not bind the'm tightly, butfwillallow the roof. sheets to move on the roof substructure. 'The clip once properly applied in'this inanner, ;there is very little "danger of its becoming knocked` sidewise along'the eaves so as to force one of the flangesto cut into the roof sheet un- 'der it, because of the provision .of the twoV points of attachment of the clip `to the sub` j structure, and the wide spacing of the ianges. Thelower surface of each flange being curved insures that even though the clip bc iinproperly'applied, or knocked out of place through accldent, 'the .contacting surface between either iiange andthe roofv connected to each other by upstanding seams transverse to the longitudinal axis of the car, and extendin to the eaves of the car, a

-clip for'movably olding the roof sheets on the car at the eaves, said clip comprising a base portion secured to the side of the car below the eaves at two points in vertical f alinement, a hood portion covering the open end 'of the seam and spaced from the top of -V the seam, and spaced from the sides and end Copies of this patent maybe obtained for ve cents each, by `addressing the Commissioner of Iatents,

of the seam*` a ,distance greater than the width of the seam, said hood portion having a flange with a ,curyed lower surface extend- 'inglaterally fromthe lower. edge of each side and adapted to'bearon the roof sheets, said anges having `extensionsbeyond' the open side of the hood, and'said flanges being connected to the base portion by yokes spaced'from the side of the. car and from ...each other, thusv providing an opening-for 'the escape of small particles from underthe hood, substantiallyas described. y 2.'A clip for car roofs composed 'of roof- `sheets connected to each other by upstanding seams transverse to the longitudinal axls of the car, said clip 'comprising a base portion adapted to be secured to the side of a car below the eaves, a hood portion having a front wall and side walls, the distance between the side walls withinthe hood portion being`over twice the width of the seam con-l necting the roof sheets, said side walls having connected to the base portion y yokea spaced from eachother and of less thickness than the base-portion, to form an openingvbelow the front'wall of the hood. g
