WILLIAM PFEIFER, or JERSEY crrY, NEW mnsmr.

CLIP FOR FASTENING ROOF SHEETS.

Application filed November 1c, 1923. Serial No. 075,054.

To all whom it may concern: Be it known that WILLIAM PFEIFER, c1t1- zen of the United States, residing at Jersey City, county of Hudson, and State of New Jersey, has invented new and useful Iniprovements in Clips for Fastening Roof Sheets, of which the following is a specification.

The present invention relates generally to fastening devices, and is more particularly directed to improvements in clips for securing or fastening roofing sheets in position on the methods followed in applying sheet roofing, especially metallic sheeting, prior to the invention disclosed therein, and have clearly set forth the advantages of my said invention in overcoming those disadvantages and expediting the work, as well as saving material, and producing better results than were previously obtainable.

The general object of the present invention is to provide a clip for fastening sheet roofing of, the general. character disclosed. in my aforesaid Letters Patent,- which embodies improvements thereover, whereby the application of the sheeting is further facilitated and rendered more economical and greater security and permanence in the locking of the sheeting in position on the supporting framework is obtained.

A further. object of my present invention is to reduce the cost of manufacturing clips of the general type described in my aforesaid Letters Patent, and. provide for the utilization of standardized stock material for forming the components thereof, so that my improved clip may be placed upon the market at a lower cost than has heretofore been possible in devices of the kind.

Other objects and advantages flowing from the practice of my invention will present themselves as- I proceed with the derivet 9, the head 10 of which is integrally scription thereof, and I would have it clearly understood that reserve unto myself all rights to the full range of equivalents, both in structure and uses to which I am entitled under my invention in its broadest aspect.

For the purposes of the present'd-isclosure, l have elected to show a preferred embodiment of my invention, but my invention may take other forms to meet special requirements, without departing from the spirit and scope thereof as defined by the appended claims.

In the drawings Fig. 1 is a view in perspective of a section of corrugated roof sheeting secured to a purlin, by the employment of my improved form of clip;

Fig. 2 is a view partly in section showing the cooperative relation of my improved clips with the purlins of the roof framework and the sheeting, the rivet of one of the clips being used upset;

Fig. 3 is a view showing a section of a purlin in elevation with my improved clip in functioning engagement therewith, and with a section of sheeting; and i Fig. 4 is a view in perspective of my improved form of clip. I

Referring now to the drawings in detail,

in which like characters of reference are employed to designate similar parts in the several views, 7 indicates the base member of my improved clip, forthe production of which, I preferably employ strip metal of a standard stock size. The strip. metal is out in the requisite lengths for providing the base member 7 and the hook portion 7",

which is formed by bending the material over on its self so that the'said hook portion and the base member will hayea spaced relation, to. permit of locating the chp in position on the roof frame work members, as hereinafter described.

- e Mounted on the upper surface of the base member 7, at the end opposite to that from which the hook-portion 75 is -formed,,is a

' method which wi ing sheets, so that, froin the description of.

my invention thus far given, it is evident that the production of my improved clip ma be carried out at a minimum of cost, an that when the components thereof are assembled and united, as ex lained, a unitary structure is obtained whic possesses great durability.

In the application of my invention to a roof structure it will be observed that the base member is ada ted to rest upon the up per surface of the ange 11 of the purlin 12, so that the reversed or hooked portion 7 will engage the underside of said flange, as clearly shown in Fig. 2. The sheeting 13 is then located in position and perforated by striking the surface thereof with a hammer, or other implement, at the point where vthe end of the rivet is in contact with the same. When the sheeting has been driven down over .the rivet to its seat upon the block 8, a washer 14 may be located uponthe rivet, after which the head of the rivet is upset, as shown at 15. Of course, itwill be evident that -the employment of the aforesaid washer 14 is not essential to the successful practising of my invention, as the 11 set ting and s reading of the free end 0 the rivet 9 wi prgvide sufficient surface for engagement with the sheeting to insure a permanent fastening.

,From the descri tion of the manner, in which my improve clip is employed, it will be evident that the block 8 provides a rigid support for the rivet so that there is no possibility of the material, of which the clip is formed, yielding under the im act of the hammer blowswhich would be likely to result in an imperfect joint, and would perniit the sheeting to vibrate to an extent, which would eventually impair the efliciency of the sheeting as a protecting covering.

In the production of my im roved clip any ferrous or non-ferrous met suitable to this purpose may be employe If a ferrous metal is used," the period of usefulness of the clip may be increased by putting it through a galvanizing process which will prising a base' member ing nut threaded onto said bolt. This latter form of structure will be especially useful in temporary work, or where it is desired to locate the sheeting preliminary to carrying out the final operations.

What is claimed is:

LoA clip for fastening roof sheets, comprising a base member formed of strip metal, one end of said base member being reversed to form a depending hook portion, and a solid upstanding block of material supported at the extremity of the other end of said base member and forming a art of the upper surface thereof, said soli block being adapted to carry a rivet.

2. A clip for fastening1 roof sheets comaving a reversed portion forming a dependent hook at one end thereof, a block of material supported from the other end of said base member and forming a part of the upper surface thereof, and an integral and upstanding projection carried by said block ada tedto ass throu h the roof sheeting, Where y the ater may e secured in functioning position.

3. A clip for fastening roof sheets and the like, comprising a base member having an integrally formed hook portion space from the underside thereof, an upstanding and integral solid member forming a part a of the upper surface of said base member at one-extremity thereof, and a rivet supported from said solid member.

4."The combination with the sup orting frame-work of a roof construction, 0 means for rigidly securing metallic sheeting thereto, said means comprising a clip having a base adapted to be supported upon the u per flange of the purlins of said framewor and formed with a depending ortion to en ange, an upj gage the underside of, said standing and integral boss provided on the upper surface at one extremity 'thereofsaid base and'an upstanding pro ection on saidboss adapted to pass through said sheetin whereby said sheeting may be immovab y clamped tosaid purlins.
