(Cl. 72—122) 5, This invention relates, in general, to a form was impaled on the projecting nails until it was clip or brace and is particularly adapted to be used in connection with the protective coating of supported in the desired position. This practice has several disadvantages among exposed metal surfaces. ‘ More particularly this invention is adapted to be used in the process of applying coverings of cementitious material to the exposed surfaces of metal structures whether for the purpose of insulating, waterproo?ng or ?reproo?ng, or for the which is the dimculty of accurately positioning the shooting strip on the supporting nails so that ‘5". 10. sake of ' appearance. ‘ Another difficulty is encountered in attempting to suit ably place shooting strips at corners or the outer edges of ?anges and the like. Hence, one of the principal objects of this in-~ llo'i In the art of structural steelwork, although not necessarily limited thereto, it has become a more or less regular practice to plaster the exposed portions of the completed metal structure 15, with a cementitious mixture forthe purpose of protecting them from the ‘elements. As known to those well versed in the art, this is commonly done by a methodknown. as the “Gunite process”, or “Guniting”- As carried out, 20 this embodies the use of a cement gun through which the mixture is forced by compressed air. a true guide line or surface is de?ned. vention is adapted to purpose 0f Another to provide a metal clip or bracket be attached to a metal surface for the Supporting objects therefrom. object is to provide a metal clip or support which may be readily attached to a cor~ 1g. ner surface for the purpose of suspending or supporting objects therefrom.

These are usually thin wood strips or boards which are erected near the line ' this application, in which: of intersecting or adjacent surfaces. vThey are used either for the purpose of sighting the true Fig‘- 1 is a View in elevation Showing a We ferred embodiment of the metal form clip adapt 40 edge line, or for actually molding each corner or ed for use on either ?at or corner surfaces. arris. Where the surfacing is to be completed by hand they provide a convenient guide for the Fig. 2 is a view similar to Fig. 1 showing a modi?ed form of clip also adapted for use on trcwelling operation. flat or corner surfaces. ‘ One of the chief difficulties encountered in this 45. type of work has been in connection with the erection of the shooting strips. Ordinarily the only available surface to which they may be attached is the very surface which is to be coated. Since it is impossible to nail the strips to the 50 metal work the common practice has been to weld the head of an ordinary nail to the metal surface with the body portion of the nail substantially normal to the surface. A series of these nails were so disposed at convenient points 55v about the surface and the wooden shooting strip _ the accompanying drawing forming a Part Of 40 . Fig. 3 is an elevation view of a modi?ed form of clip designed for use on flat surfaces. 45 Fig- 4 iS a View Showing a form 01119, of the type shown in Fig. 1, positioned on the edge of a metal member. Fig. 5 is a view in elevation showing a form. clip, of the type illustrated in Fig. l, positioned 15!): on a ?at metal surface; and, Fig. 6 is a view showing how the clips may be used to support guide strips for a ?oat board. > In accordance with my invention, I provide, as shown in Fig. 1, a metal strip or plate H which 55. 2 2,124,982 is preferably cut from strips of thin metal stock having the desired physical properties. The ends of the clip H are irregularly shaped, which shaping may be done in a single cutting operation or the shaping may be done in subse quent operations. The lower, or tail end of, the clip is formed with a notch i2, the vertex of which is on the longitudinal center line, thus giving the end‘ a 10 ?sh-tail appearance. As shown in the drawing, the notch I2 is a right angle, which is most de When a plurality of such clips are placed along the edge of a metal surface to support a shoot ing strip, as shown in Fig. 4, the outer corners of the clip shoulders may be used to sight the imaginary ?nish line. By applying the cemen titious material on both surfaces until the sides of the clip are covered, a bevel edge is formed on the corner of the ?nished structure. This bev- _ eled edge is as wide as the width of the clip. After the coating has been applied and has 10 sirable for use on corners where the adjacent) solidi?ed, the shooting strips are removed leaving the spike, I1 projecting from the beveled edge surfaces meet at a right angle, although for corners having a different angle a corresponding protruding, or may be clipped off or bent over 15 notch angle may be used. of' the coated surface. The spikes may be left flush with the'beveled surface. , The notching operation results in the forma tion of two projecting points l3 and M which may be bent in either direction along their‘ broadest surface to form feet upon which the 20 clip may rest in an upright position as shown‘ ‘in Fig. 5, or which will give a broad contacting area when held against any: surface. Since the clip is designed primarily to be sus pended from metal objects or surfaces, the feet 25 formed by bending the points i3 and I4 may be easily secured. to the metal surface by welding. In actual usage this operation may be speedily performed. The workman merely grasps the clip, bends the points l3 and I4 over in either 30 the same or opposite directions with a pair of pliers, holds the clip in position against the metal ' structure and welds the feet, formed by bend ing the points over, to the metal surface as illus trated in Fig. 5. A series of these clips may be 35 disposed along the surface at spaced intervals to provide a plurality of‘ supports for the shooting strips. The tip“ portion ofthe spike I‘! is made blunt in order to decrease its tendency to split the shooting‘ stripswhen. the latter are of thin wood material, as is commonly the case. However, with different materials or under certain condi 20 tions it is contemplated that pointed spikes may be used. . v ‘ It will be'noted. that the portions of the shoul ders 20 and 2| immediately adjacent the base of the spike I‘! are out out below the shoulder line 25 at 23. The purpose of cutting away in this manner is to provide a minimum of exposed metal. surface when the shooting strip is re moved. Where it is desirable or necessary to ?nish 30 with a square, instead of a beveled, edge, the coating material may be directly applied in that fashion by sighting to‘ the point where. the imag inary center line of the clip intersects the under surface of the shooting strip. This point, which 35 is designatedl?fin Fig. 4 is more easily located because of the cut away portions 23, it being With the construction of the clip as: shown in Fig. 2, it is obvious that only one foot support merely necessary to estimate the center of the thus may be more readily applied, it requires more welding to give it a degree of sturdiness equivalent to that obtained where the bent over 50 points are used. To secure this clip to the ?at after the‘ coating is applied, and in which me chanical levelling means may be employed to obtain a smooth ?at surface. The clip is se cured to the corner of the workpiece, as before, and: a‘narrow strip of wood 25 is’ impaled on the base portion of thespike I1 and to deposit the 40 may be formed since only one point 15 is pro- - materialup to that point. Obviously when the 40 shooting strip is removed not only the spike ll, vided. The types of clip shown in Figs. 1 and 2 when attached to a ?at surface form a very rigid but also portionsof the shoulders 20 and 21 will project through the surface of the coating. and sturdy support. 7 Fig. 3 shows a clip with a squared end. While These may all be clipped off. Fig. 6 shows a method of using the clip in 45 45 this type of clip eliminates the operation of bending over the end points to form feet, and which none of the metal parts will be visible metal surface, weld metal is applied along the lower edge. Where the cementitious coating is to be applied to an irregular’ surface, such as the corner of a 55 beam or ?ange, it is sometimes desirable tosup port the shooting strip at an angle to both sur faces, as is shown in Fig. 4. To do this, the clip is placed on the corner of the structure or work piece !6 with the corner ?tting into the notch 60 12. Weld metal. 51 is then deposited along the intersection of the sides of the notch 12' and the surfaces of the workpiece. The central portion of the upper end of the clip is extended to form a spike I8, the tip of 65 which is cut to form a flat end I9. To either side of the point I‘! are formed shoulders 20 and 2|. In placing the shooting strip 22in position, it is driven on to the spiked portion l1 until the 70 strip contacts the shoulders 26 and 2|. The shoulders act as a stop or guide to maintain the distance between the workpiece l6 and the shooting strip substantially uniform, -so that an even layer of material may be applied in the 75 “Guniting” operation. ' " ' ' spike H; The coating 'material is’. then deposited to the outer edge of the wood strip. When this has 7 been‘ done to'both sides and the material has 55 set, the wood strip is pulled .off the spike, thus 'leavinga channel in the cementitious material. This channel-is then ?lled with the coating ma terial and trowelled‘to form either a beveled or a sharp corner. ' 60 ' To coat‘ a surface having two opposite edges, the clips are placed and welded, as shown, on the opposite corners, the wood strips 25 are drivenonto the spikes l1, and the cementitious material is. sprayed on the metallic surface to a depth sufficient to cover the outermost corner of the wood strip 25. A “float board” 26, such as is commonly used in smoothing and levelling cement work, may then be slid along the edges of the'wood strips to trim off the excess of coat 70 ing material. In this way a ?at, level surface is assured. , From the foregoing it will be observed that I have devised a simple and efficient means for attaching forms to metal structures which not 2,124,982 only supports the same in any desired position but also serves as a guide means to insure uni form application of the cementitious coating. the unextended portion forming a shoulder to limit the penetration of said spike into the form or guide, the opposite end of said body being ir While this invention has been shown in but regularly extended to form a portion bendable three forms, it will be apparent to those skilled transversely of the plane of said body to provide in the art that it is not so limited but is sus a foot which when placed against a surface of the form offers a substantially broad contacting surface for the purpose of welding, the foot end of said body having ?at edge surfaces extending ceptible to various other changes and modi?ca tions without departing from the spirit thereof, and it is desired therefore that only such limita 10 tions shall be placed thereon as are imposed by the prior art or are speci?cally set forth in the appended claims. I claim: 1. A form clip adapted to be welded to metal structure members for the support of forms or guides in spaced relation thereto comprising a ?at body of weldable material having one end extended longitudinally to form a spike adapted for limited penetration into the form or guide, and the opposite end cut irregularly to provide extended portions bendable transversely of the plane of said body to form feet adapted for en gagement with the surface of the structure mem ber for the purpose of welding thereto, the sides of said extended portions being formed to en gage in abutting relation the adjacent surfaces at the corners of said structure members. 2.
