ToaZZ whom t may concern:

Be it known that I FRANK D. MOON, a citizen of the United tates,l and a resident of Englewood, in the county of Bergen and State of New Jersey, haveinvented a new and Improved Self-Locking Clip, of vwhich the following is a full, clear, and 'exact de for securing the 'corrugated sheets to roof purlins whereby the roofing sheets maybe attached rapidly and Securely to the'purlins' scription.

This invention relatesgto building oon'- struction" and has,` particularreference to means for attaching corrugated sheets of 'metal2 or their equivalent, to metal supports or channels in tlieerection'of metal buildlngs. i

Among the bjects, therefore, of the invention is to improve the attachment clips and with the minimum amount ofdanger or labor on the part of the operators.

A furtherobject-of the invention is to. provide a 'clip that shall be self locking with respect to its engagement withv theupper or outer flange 'of a channelv shaped pui-lin and which when attached and 4with the sheet secured thereto shall be held from any possible displacement .from the .purlin flange in any direction., n Another object of thel invention isto provide an attachment clip for corrugated sheetsv that may be attached in'such a manner as to prevent-all possibility of rattling I .of thesheets, either as roofingor siding.

- With `the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while theinvention isv not restricted to the exact 'details ofconstruction disclosed or suggested herein, still for thepurpose of` illustratihg a practical embodiment thereof reference -is had to the accompanying drawings, in

tion of a metallic roof and siding illustrating `my improvement. I

ofthe special` clip applied to the *lowers* most purlin having its upper an'ge.at an cross sectional form and relation to the I Supporting fiange and sheet connected thereto; and

Fig. 7 is a View of the character of Fig. G but indicating a lslightly modified form Referring now morel particularly to the l drawings I indicate generally in Fig.` 1 the object ornature of the invention with respect to a metallic building including a postlO, rafters 11 and any desired number of horizontally extending angle girts 12 vand purlins 13 and lato' which siding and roof.-

.ing 4sheets 15, preferably of corrugated metal, are connected by I neans of the special clips which per se constitute this invention.4 --I will first describe the constructiony and operation of the standard clip with refer, lence particularly vto Figs. 2, 3, v5 and 6. i The clip as a' whole is indicated atl 16 and is .made from a single pieceA of stron sheet material such as a good quality of galvanized iron or other suitable or equivalent material. Fig. 2 shows the iat form ofthe clip after it is stamped out`.but be fore it is bent into the arch-shape in which it is used in practice as shown in the other figures. The clip -comprises a body. pon tion 17 which in its operative form constitutes a rigid channel and withrespect to stiff corrugated sheeting projects into one of the' Y corrugations and lies therein parallelto the corugationand between the crest there-v of and the supporting member to which the clip is connected and serves to secure ythe sheeting.

Broadly speaking and irrespective .of the specific construction of the clip body itis provided at one end with a hook for extension inward and embracing engagement around the free edge 18 of -the flange 19 of. either a roof purlin, siding -girt or any other supporting membery -having a flange corresponding to .the building elements illustrated. At the other end the clip is provided with a spur or analogous engaging means to snugly embrace or. engage over the outside of the flange and prefer-V ably just below the base portion thereof asv lVhen the clip is con-- indicated at 20. structed of sheet metal in the mannerillustrated in Figs. 2 and 6 it comprises two of the aforesaid hooksindicated at 21'spaced from each other in a direction of the flange y and embracing therefore two spaced points mentJ as ar`e also'the spurs 22, the manner` vof applicationand use of the device will be '25 or `portions of the flange,` and likewise the hooks indicated at 22 are preferably duplicated for spaced engagement with the base portionof the flange. stood, however, that the particular number 'or arrangement of these engaging and interlocking features are subject to considerable variation in scope so long as the general principles herein enunciated and claimed are not departed from.

'With the clip body bent into arch hooks 21 are brought into transverse alineap'preciated. The hooked portion 21 of the clip is first projected-inward so as to engage over Orembracethe free edge 18 of the vflange as shown in Fig. 3, the sldes of' the body above the points of the hooks being cut out as indicated `at 23 to provide a clearance for the admission of the extreme edge of the flange. The clips are made of standard sizes turalflanges, andv after the application of 3(5the hooked portion of the clip as 4shown in Y f downwardor inward over the edge or angle at the ,base20 of the flange.Y The clip lis so lof the flange and with the points 22.V thereof' have some gripping action overtheV outside having a bearing-contact against said' base.

, From this description it will be appreciated that the.v hook or hooks serve immediately two purposes, to -prevent Vmovement of the clip toward the hase 20 and to prevent. movement of the hooked end ofy the clip upward.

- or outward from the ange. The spur or-v t spurs 22, so lon asv they are in interlocking engagement wit the base of the Bange serve as a positive means to prevent displacement of the clip lsuch as would permit .the disengagement of thelhook or hooks, and ,when y the attachment is completed as described be- .low there can be nov disengagement' of the spur or spurs from the basel 'of the flange.

At any'desired place between thehook and the spur portions of the clip I provide on the sides of the clip, when made of sheet metal as illustrated or when made of other material at any convenient place, one or Itis to be undershape as shown in Fig. 6 so that the points ofthe relatively close to the active points of the hooks 21. l

The hooked end pprtion of the body is of the flange through which any suitableV binding fastener such as a screw bolt 26 having a nut 27 may;I be passed forattaching a crest of one corrugation o f the-sheet ll'to the clip while Vthe inwrrdlydirecfed corrugations lie directly in place upon ,or against the outer face of the flange. I also preferably employ a soft metal washer 28 between the outer end or head of the fastener and thesheet-to make a watertight joint in accordance with the usual practice. In the practice of my. invention the effective height of the arch of the clip, see Fig. 6, betweenthe outer face of thel flange and the inner surface of the crest s ofthe corrugatedjsheet 15'is appreciably lessthan the height of the said crestyso that when the binding fastener 26 or its equivalent/is passedI through the` sheet and crown `of the arch and tightened, "said fastener has the effect of bindin the provided with a hole orh'slot 25 preferalby -in the longitudinal center of the body and lv upward or outward from the free edge 18v parts firmly toward each other but still eaving a slight space between the sheet and said crown. .This results in the provision of a. lmost effective fastenin I and obviates any possibility of rattllng ofthe sheets. Theaction of the fastener furthermore drawing 4,the crest of 'the 4corrugation down towar the flan' e and reacting to draw'the hooked end of t e clip upward or outward into firm engagement with the inner face 4of the flange tends to tilt the spurred endgofthe clip inward until the contact point or points 24 comeginto secure supportingjenga ement f' with the outerface ofA the flange.

t willA thus be seen that a clip made in accordance with the disclosurelleleinis not only adapt ed to lock itself upoI't'heaigle-flange and so be heldfrom accidentahdisplacement durling the -operation of attachingthe corrugatedsheets,butf'also will prevent any 0slio sible movement' of' the attaching means' at,

erally or outwarfhwitlifregiect' to the flange.
