`ments in Clips for Fastening. Roof-Sheets,

of which the following is a specification.

This invention has reference to improvements in clips for fastening roof sheets.

f It pertains particularly to improved clips used in roof constructions in which the roof sheet is fastened by means of rivets that pass through the clips. The rivets finally are forced through the roof sheet and flattened whereby the said sheetis per- In order to render it possible to flatten the rivet that passes through the clip the rivet head must be supported from below to offer suflicient resistance. This is accomplisledibyholding a dolly against the rivet hed'iwhile the rivet is flattened. To effect that.. an employee is required to press the dolly/.gainst the rivet head from underneath the' roof while another employee flattens the rivet. Itl is evident that this ,method is a source of loss `in wages and timeas practised with clips heretofore employed. It further happened quite often with this method thatholes were made inthe roof sheet in wrong locations which holes had to be closed bysoldering or the damaged sheets had to be cut up for other use which resultedin a loss of material. Such clips were then hammered against the lowerj'surface ofthe upper .lateral portion of the purlin which permitted of slight vibrations of the nished roof.

The presentninvention has for its purpose to produce improved clips for fastening "roof-sheets or roof coverings by means of p portion of a roof. Fig. 2 illustrates in side the'roof sheet until he finds the rivet.

elevation an improved clip applied to a purlin with the roof sheeting' resting on the rivet. 'Figa 3 is a vfront elevation of Fig. 2 showing the roof sheet fastened and the'rivet attened; and F ig. 4 is a perspective View of the improved clip.

Similar characters of reference denote like parts in all the figures.

In the drawing in Fig. 1 a represents a principal rafter or roof truss whichsupports the purlins Z); 'The clips are applied to the top horizontal portion of the purlins as shown-in Figs. 2 and 3. The purlin 'b illustrated in Fig. 2 is of about -natural size and strong enough fora roof to Withstand storms. The clip c shown in Fig. 4 also is of about natural size and ofthe shape in which itis manufactured. The improved clip is. made of a metal bai' and consists of a horizontal top portion c1, a parallel middle portion c2 which is somewhat longer than the topportion, and a-bottom portion c3 bent at an angle as shown. The topportion c1 has a central opening through which passes a rivet d whose head d1 is located between the middle and to-p portions of the clip and fits snugly between them. Thus the rivet forms a permanent part of the improved clip. The rivet head is of a substantial height which appears to facilitate the flattening of the rivet.

The clip' is applied to the horizontal top i portion b1 of the purlin Z) with its lower portion c3 hanging down as shown inY dotted lines in Fig. 2. lVhen the required number of clips have been placed on the purlins the roof sheet e is placed thereon which is usually corrugated as shown in Fig. 3. It is easily understood from Fig. 2 that the rivet head is substantially supported from below by the clip portion c2, the horizontal purlin portion b1 and thereby by the entire purlin and the roof truss a. For the purposeA of fastening the roof sheet and flattening the rivet one employee is sufficient who feels with his hammer along the top surfaceof Now the roofV sheet is hammered down whereby the rivet pierces the same. When the rivet is flattened it assumes the shape shown in Fig. 3 in which the flattened portion is designated by the reference character d2. In the described manner all the rivets are han1- mered down Without any support from bielow until the roof is finished. When tde rivet has been flattened the slanting portion tion, and Ineens permanently Secured beA Y tween the^top and midd surface of the VVhorizontal portion b1, of the -widthsbecause it is 'immaterial whether. the .clip extends 'a little more or lessoveij the top constructions other.
