Application July 24, 1941, Serial No. 403,871

\ s claims. '(cl. 'z2-11s) This' invention relates to securing devices ofl the type made-use of in the erection of building materials. 'and particularly for securing hard I wood, soft wood, composition nbre -boards or boards made with gypsum and covered with paper or the like to frame walls and. ceilingstructure of buildings. v

This invention provides a novel and improved means to secure lar'g'e or small boards or panels which' are pref abricated or pre-finished. If same it results in defaci'ng the material and it is obiectionable, because, irrespectivel of the painstaking and costly labor `to touch up the nailhead holes, the appearance is always marred.

v The trend in the building construction industry is to erect as large panels as possible to cover exterior and interior walls and ceilings; sincethese panels in most cases are pre-finished, blind fasteners andthe sliding floating fasteners are an absolute necessity. y' v There is another advantage in -fastening materials with the blind fasteners in that when there are no nails in the face of the boards, there. isno sound conductibility, thus making' this new fastening method sound-proof. l

Some of the fasteners of this invention include springy Wire hair-pin clips which viit snugly on the stock lumber applied, requiring no nails whatsoever. Attached to this clip is a pressed metal fastener provided with prongs extending in 'opposite directions, which penetrate the edges of the applied material. The advantages of the. device over the conventional manner of nailing are impressive because:

1. The invented clips provide 100% salvage of the material applied and the clips themselves, should same be removed or used temporarily.

2. These clips have four lateral free move- 'are secured 4with the conventional face nailing, y

ties, they are very well adapted for accurate tight-fitting square edge, tongue and groove, shiplap or any other jointdesigns that will interlock each other.

One objectof this invention is to provide blind fasteners or securing devices by means of which f the` control of expansion or contraction is takencareof; the material applied is not defaced in plied with common, ordinary carpenter tools; materials applied with them are 100% salvaged,

resulting in an inexpensive, substantial` and handsome job.. This invention is both important and necessary due to the lack of similar devices in the market.

Further, it is desired to provide'secuiing de- `vices for general utility in the building indusl,try by means of which boards, panels, etc.,'of anyA4 nature whatsoever of any building structure may f be rigidly and securely attached to beams orup- This invention also includes` blind lfasteners l designed for sliding and floatingvpurposes vwhich perform important duties'in the building industry. Because of their sliding and floating qualirights by an operator Whostands in front of the supports or on the opposite side. f\

The securing devices contemplated by the present inventionmay vary rather widely in de- Vtails of design, but in every instance will include `stamped-out, pressed metalfasteners, wire clips' and prongs which can either be nailed to structural lumber or snugly fitted. These clips Vwill always have prongs different in. designs and bending angledegrees, in accordance with ythe requirementsof the density and thickness of the boards, panels, ,etc which are to ,be fastened. y

Withlnthe scope of the invention, numerous f types of securing devices may be designed and made use of, in the accompanying drawings, several areillustrated by Way of example.

In the drawings: f y Fig. 1 is a perspective view of a'section of lumber, showing one of the improved 'fastening devices attached `to the same; Fig. 2 is a similar perspective View, in which the-pronged plate, constituting'a part of the fastener, is of slightly 'different shape; Fig. 3 is another perspectivev attached, said `frame being utilized for holding a pronged plate; Fig. 5 is a face view of a pronged plateadapted tobe held by the frame disclosed in Fig. 4; Fig. 6 is (a face view of another pronged plate, which can, like the plate shown in Fig. 5, be either nailed to the lumber or else held in place by either of the frames shown in Figs. 4 and 7 or by hair-pin clips; Fig. 'l is a front view of a wire frame operative in the manner similar to the sheet metal frameof Fig. 4; Fig. 8 is a perspective view of a section of lumber to which a hair-pin clip is attached and is a perspective view showing a hair-pinclp having its ieg portions formed with pronged ter,- minals; Fig. l1 shows another`wire clip., of twopart form on which prongs are formed; Fig. l2 is a perspective view of a portion of the wire clip shown in Fig. 11; Fig. 13 is a face View of a pronged fastener plate forming a so-called blind fastener; Fig.` 14 is a similar view ofanother fastener plate of .the blind type; Fig. 15 is a transverse sectional view through'the fastener shown in Fig. 13; Figs. 16 to 18 inclusive are diagrammatic views of several types of prongs adaptable for use in fastening sheet material in place; Fig; 19 is a perspective v'iew of a section of lumber, showing the end portions of the hair-pin clips; Figs. 20, 2l, 22 and 24 are perspective views showingfour types of plate fasteners provided with prongs of the character shown in Fig. 18; Fig. 23 is a perspective view in `section showing how the fasteners of Figs. 1 to 3 operate to hold two pieces of boardin position;

portions of the clip, it will be ,apparent that movementin both horizontal and vertical directions of the fastening device may be had.

In such cases where it is desirable to permanently and fixedly secure'the metal fastener 3 to the lumber, this may be done by omitting the wire'clip and using nails 'extending through the r nail holes 8 and entering into the lumber.

In Fig.. 2 is shown a perspective view of a section of lumber l provided with hair-pin type Wire clip 2, the clip being substantially the same as that shown in Fig. 1. The pressed metal fastener Ill has longer projecting end portions il and also longer oppositely bent prongs i2 which Fig. 25 shows a fastener adapted to be supported on the lumber by two nails; Fig. 26 is a sectional view through a piece of lumber, showing the application of a fastener of Fig. 14 thereto; Fig.

27 is a diagrammatic View of a special form of prong; Fig. 28 is a perspective view of'a portion of a wall, showing al large board applied to the studsby the improved fasteners; Fig. 29 is a sectional view, showing penetration of the prongs into the wall board; Fig. 30 is a sectional view at.

right angles to that of Fig. 29; Fig.`31 isa face View of the blank fromfwhich a sheet metal nail-like fastener is produced; and Fig. 321s a side view of the finished nail-likefastener.

In Fig. 1 is shown a perspective view ofv a fragment of lumber or a beam l, engaged by a Awire hair-pin clip 2, said clip being formed of drawn wire of suitable strengthl and resilience to enable it to securely engage and maintain it` y self upon,the beam. The spacedfleg portions of the clip pass through parts' of a pressed metal fastener 3, provided with two orv more sawtoothed prongs 4 and 5 extending in opposite directions. `These toothed prongs are formed on the endof a projecting flange 3a and one of these prongs penetratesrand extends into the edge of 'the board 6 (Fig. 23) for a suflicient distance,

to furnish morethan theminimum of support required for holding the board in position. The

' prong 5 projecting in the opposite-direction penp etrates Ainto theyedge'of the adjacent board 'I right angles' tothe flange 13a and. thus, when j-they penetrate into the edges of the board; they yextend, therein and are located substantially parallel with the outer surfacefof the lumber I and at a sufficient distance from saidouter surfaceand not less thanAone-half of the thickness of the board used. This clip can b e'arranged,

are necessary to fasten heavier boards or panels in position. Otherwise, the advantages and functions attained by this fasteningdevice are similar to those of the clip disclosed in Fig. 1.

In theembodiment of the invention disclosed lin Fig. 3, the hair pin clip 2 extends through the projecting flange 3a of a pressed metal fastener I3 which is substantially H-shaped. Said fastener I3 is provided in its spaced apart leg portions Ida with projecting ridges or ribs IIE protruding to a greater extent than the legk portions of the wire clip 2. These protruding ribs or ridges provide firm contact against the back of any applied material held by the fastener i3, such material, for example, being glass or mirrors cemented on boards. Since the applied material rests against, or rides on, the ribs or ridges Ill in track-like fashion, any slight variations in the shape or positioning of the hair-pin clip 2 does not eiect the true' plane of the two applied pieces of sheet material, because ofthe clearance space between the ribs or ridges ll and the hair-y pin clip 2.

Fig. 2 discloses a fragment of lumber I with a front view of a sheet metal stamped-out frame I5 applied to the face of the lumber and attached thereto by means of the two spaced nails I9. -Thisframe is adapted for use in holding the fastener IB such as shown in Fig. 5, or any other blind type. By a blind fastener is meant one which penetrates into the back face of the panel and clinches over within the panel without penetrating completely through it, and without being discernible from the front face of' the' panel. The frame I5 is formed with two nail slots I'I,

` said nail slots being widest at their ends so that shifting movement of the frame may not only take place transversely of the beam, but also angularly, if such. movement is necessary.

In Fig. 5 is shown a front View of the stamped out pronged blind fastener I6 which can either be nailed on a wood structure member for stationary purposes or it can be used in connection with a stamped-out sheet metal frame such vas 1shown' in Fig. 4, or witha wire type suc'h as shown in Fig. 7 and hereinafter described. The several prongs 2|, which hereinafter are described in detail, normally extend at approximately to the body of the fastener and curl or clench over within the applied board. The fastener I6 'is provided with two tongues 20 which, when the vfastener is used in connection with a frame, such as shown at l5, are bent around the segmentally shaped side members I8 of the frame 4 I5, as shown in Fig. 4, to slidably hold the fastener I6 between the frame I and the face of the lumber I. The segmentally shaped side members I8 permit angular movement of the fastener ,with respect to the frame. 'I'he engagement of the fastener I6 with frame I5 is thus one which permits the fastener t'o move vertically on the "two side members I8 when such movement is necessary.

In Fi'g. 6 is disclosed a front elevation of a six-pronged blind fastener 22 formed with prongs 2I. This fastener can be-either nailed on` structural framework by nails extending through the holes 8 or it can be used in connection with a sliding, `floating wired clip 2 or frame I5. The

' lumber.

Y 3 tions of the cup' Werne-the front 'face f die beam, and are bent at right angles `to extend over an edge of the beam and are then bent down to overlie the rear face of the beam, as shown in Fig. 19, the two leg portions being thereconnected into U or V shape as indicated at 40 and 4| in Fig. 19. The back portion 40. properly termed a goose-neck back for the clip, has the two points of contact, indicated at 42 and 43, against the back of the beam, and since a back of this form protrudes slightly from the back of the beam, it

is employed wherever there is sufficient' space `behind the beam.v

The back portion shown at 4I is at and the same is in completecontact with the back of the This.. can be used where there is no space behind the beam for the 'employment of the type indicated at 40'. `While the clip 2 is shown as consisting oftwo spaced connecting leg por,-.

prongs 23 of this fastener extend at approximately 90.o to the body of the plate 22 and as described in Aeonnection with the fastener of Fig.

5, these prongs curl or bend over within the body of the sheet material to thereby hold the sheet material in position. v

In Figs. 1'? and 18 is disclosed prongs similar to .those shown in the fastening members of `Eigs. 5 and 6. These prongs are provided with a number of stepped sections; the wider portion 504of the4 prong is situated adjacent to the base .or `body of the fastener on which the prong is formed. Located at a predetermined distanceaway from the point of connection of the prong with the base or body of the fastener isa step or shoulder 5I and projecting vtherefrom is a thinner or narrower portion 52 of the prong which may gradually taper until it terminates lin a. needle-like point 53. The arrangement of this type lof prong is such that in usethe needle-like termination orpoint v53 first' penetrates into the e wall board and starts to bend over therein. When ,f

the wall board reaches the shoulder portion 5I ofthe prong, a greater resistance to penetrate occurs and a greater binding of. the narrowerv or thinner portion ofthe prong takes place. 'I'he 1 actual point of bend or the narrower or thinner portion 52 is at the shoulderv 5I. Accordingly,

the position of this shoulder with relation to the entire Alength of the prong is that which determines the extent ofpenetration of the prong within the wall board. Thus, if it is desired that the prong penetrate for a considerable distance vthrough the board, the shoulder V5I will be located relatively close tor the"point of joinder `of the entire prong with the face portion of the f fastener such as shown 'in Fig. 18. `,On the other hand, when a relatively deep penetration of the prong into thev board is desired, the shoulder 5I br point of bending of the prong-will Ibe relatively remote`from the point of joinder of the prong to the base portion of the fastener. A rIfhus, 1 the position of this shoulder or of aseries of such shoulders which might be used in successive stepped formation,`the bending of th'eprong can be controlled and re/sultantlyftheA extent to 'which the prong penetratsfinto the board is also accu-` rately e, governed.

tions, it is also possible to use single wire types in spaced relation or in groups. Such a single wire type' is shown at 44 in Fig. 19 and this. type can be used in pairs or in groups of more than provide guide-ways through which the'legs ofI `the .wire clip `2 may pass.

These guide-ways 41 permit slidable adjustment of the fastener 46 in the manner previously-described with respect to the other fastener members. The fastener 46 is providedv with punched-out prongs 48, which prongs may be of the form shown in Fig. 16 or elsel may be'of any of the other forms herein described. f l

In Fig. 9 a plate 46- similar to that shown in Fig. 8 is disclosed. `In this embodiment of the invention, however, fastening prongs 49 are in the form of wirelstaples held by or locatedbehind the fastener plate 46 and protruding .through the same and forwardly to penetrate the wall board pressed'against them.

In Fig.v 10 the legs'of the clip 2 are provided With out-turned pointed terminals or prongs 65 which penetrate directly into the wall board.

In Fig. 11 is shown a hair-pin clip v2 provided 'with'.vtwo outwardly projecting pointed terminals orprongs 66.1 'I'his clip 2 has its leg portions exT tending around three,I sides of the lumber, said leg portions terminating in a loop 61, seen in Fig. 12. A triangular-'shaped piece of wire 68 extends over the two prongs 66 and thisis provided with a projecting prong 69 and a hook portion In engaging in the loop 61. IIlhis is a so-called blind fastener and provides three projecting prongs,

' namely, those shown at 66 and 69, penetrating into the wall board.

In Fig. 13 is shown a front view of a fastener stamped out of sheet metal, the sarnebeing pro- The frame so isieisclosea in Fig. '1 and-is. simi-r l lar in operation to that consisting of sheet metal indicated at I5, except that the jframe/30 is corn` posed of 4wire.

.In Fig. 8 a' hair-pin clip 2 is shown, similar to that shown in Figs. 1 2 and 3. In embracing a beam or other piece of lumber, the two leg porvided with two prongs 'II which may be of any of the shapes herein described. Thesetwo prongs are adapted to penetrate -into the wall board. `xtending laterally from the side edges 12 of the plate are fastening prongs 'I3 which are notched or cut in herringbone formation. These prongs 13 are bent so asto penetrate into the sides of the beam.

In Fig. 14 is shown a front view of another type of blind fastener. This fastener includes a strap portion lll having pointed ends 15. The strap is bent around the beam as shown in Fig. 26 and the pointed ends 'l5 are forced into the opposite sides of the beam. The prong portions 16 and 11 are bent forwardly for entry into the wall board.

In Figs. 20, 2l, 22 and 24 are shown various types of sheet metal fasteners with prongs bent laterally from the edges thereof, the prongs being of the type shown in Figs. 17 and 18, and previously described. These are examples ofseveral forms in which the fasteners may-be made and it will be obvious that the fasteners may also be made in a number of other forms to suit different requirements.

In Fig. 25 is shown a blind clip or fastener which may be held in position by a nail liB. The nail engages in an angular or V-shaped notch 'i9 and by reason of this arrangement may be inclined or adjusted While one of the prongs 8B is engaged into the edge of one of the boards. The nail mayalso be entered through the hole 8 and the other prong 8i \engaged with the edge of the second sheet of board. This fastener may be solely held by the nail i8 and that entering through the hole 8 or be supported by sliding, floating framessuch as shown in Figs. 4 and 7.

In Figs. '31 and 32 is shown a fastening nail composed-of pressed metal. In Fig. 31 the blank from which the nail is formed is disclosed, said blank being -provided 4with a central disc shaped portion 32 from .Which extend the'two serrated prongs 83. each of these prongs terminating in point 8d. Inl producing the nail, the two prong portions 83 are bent at right angles to the plane of the' disc or head 82 resulting in the'finished -Lio product shown in Fig. 31, While the nail is disclosed as having'two prongs, one or more prongs may be used, the features of the invention being therein included. It is also possible to form the prongs likethose shown in Figs. 17 :and A18, and by which the extent of penetration of the prongs into-the board'may be determined. This composite nail is adapted for use in fastening building materials such asl w'ood, composition, sidingS,

shingles and similar products inv building construction. When thenail is applied in place, each blow of the hammer results in the bending and supporting ,oftheprongs 83,both sideways and flat. This isdue to the lfact'that the undulating or notched arrangement of these prongs, such .as illustrated at 85 in Fig. 2.7, permits buckling or bending over at these weakened points.

. Thus, when these nails orpron'gs are bent over within the board, it insures a solid grip upon the material. l l v While I have shown and described a number of embodiments of the invention, it is obvious that various modifications may be made Without departing from thespirit of thewnvention. ;The primary purpose of the fastening `means disclosed is-to provide penetrating prongs on a. fastener which may be used to securely engage and hold y 2,325, lumber or beam and thus fasten the plate to the 4 768 l 1 the importantvmounting or support of the clip by which shifting in practically all directions is possible to compensate for expansion and contraction of the beam, as Well as to enable the clip to be adjusted to more readily engage the Wall y board at the points indicated.
