8 Claims. (Cl. 'l2- 118) My invention relates to fastening devices and more particularly to fastening devices of the type for securing and attaching fibrous or cork wall boards, tiles and the like.

The invention has for one of its objects to provide a fastening device for rmly connecting wall boards and the like to eachother and to wood furring, joists and studs without exposed nailing. Another object of the invention is to provide a fastener capable of penetrating a side edge of a wall board at an angle of approximately Features of the invention residing in advantageous fo-rms, combinations and relations of parts will hereinafter appear, and be pointed Aout in the claims.

In 'the drawing:

Figure l is a perspective view ofthe fastening device. y

Figure 2 is a plan view of the device.

Figure 3 is a side view of the device.

Figure 41s a plan view of a blank of sheet metal from which the fastening device is formed.

Figure 5 is a sectional view of a wooden furring strip and adjacent "portions of neighboring wall boards illustrating the manner in which the fastening device is associated therewith.

Figure 6 isa front view of adjacent portions of neighboring wall boards in position to be connectcd by the fastening device, the fastening device being shownas having been connected to oneof the boards.

Figure 'l is a front view of a plurality of boards, each provided with a number of fastening de.- vices, one of the boards being shown in the. position it occupies just'prior to being connected by the fastening devices to the otherl boards.

Referring more particularly to the drawing, the fastening device indicated generally by the reference numeral I is preferably formed from a single blank of sheet metal of the'form illustrated in Figure 4. The fastening device includes a web 2 Awhich is adapted to be interposed between the adjoining edges of neighboring wall boards 3 and base portions 4 which project on opposite sides of the web to overlappingly engage the inner faces of adjacent portions of neighboring boards. The fastening device also includes prongs 5 which are adapted to penetrate the adjoining edges of neighboring boards, each prong being arranged so as to overlie the base portion projecting from the same side of the web as the prong. It will thus be perceived that the fastening device generally comprises two oppolsitely 'disposed substantially identical channelshaped portions, each of which includes a base, a web and a prong.

The base portions 4 preferably project from the lweb a greater distance than the prongs and the .portionsof neighboring boards gripped or engaged by the fastening device are each of 4such area that a` rigid connection is obtained between the boards without the necessity of nailing the fastening -device to the boards or to joists or furring. However, in order that the fastener may, if desired, be secured to an adjacent joist or furring strip, each base portion thereof may advantageously be provided with a nail receiving opening 6.

The prongs 5 project obliquely from the web and preferably form therewith substantially equal angles which face in the same direction. Moreover, the prongswhich are o f substantially ltriangular shape have their side edges inclined in the V same general direction with respect to the web and they preferably define an angle Whose bisector is disposed at an angle of approximately 45 to the web. By forming the prongs in this manner, they may penetrate the side edges of lthe board at an angle of 45 withta minimum tearing or cutting of the boards.

The manner of forming the fastening device from the blank illustrated in Figure 4 will, itis thought, be evident. The two'base portions designated da in Figure 4 may first be bent in opposite directions about the axis X and then the prongs designated 5a. in Figure 4 may be similarly bent about an axis Y.

In using the fastenugdevice, it is first ar- Vranged with relation to the board with which it is to be associated, `so that one of the base portions is disposed in lapping engagement with the inner face of the board and the pointed end of the prong adjacent that 'base portion abuts the edge of the board *to be penetrated. Pressure is then applied to the fastening device causing the prong to penetrate the edge of the board at an angle of approximately 45 thereto. The other base portion of the fastening device may then be nailed, as illustrated in Figure 6, to a joist or furl ring. should eitherbe available, but this is unnecessary to insure a rigid joint between the boards. The next board or tile is then pressed upon theexposed prong 'of the device atan angle of approximately 45, the board, of course, being so disposed that its inner face will be in engagement with the adjacent base portion.

`Upon referring to Figure -7`of'the drawing wherein one of the boards is shown in position to be connected to other boards, it will be perceived that it is only necessary to move the unconnected board at an angle of 45 to effect its connection to the other boards. Thus, since it is unnecessary, as is required by previously devised fasteners, to first move the board in one direction to cause the fasteners to penetrate one edge and then in another direction to cause other fasteners to penetrate an adjacent edge, it is evident that the fastener of the present invention enables wall boards and tiles of relatively hard or dense material, as well as those of comparatively large size requiring two or more fasteners on a side, to be effectively and easily secured together.

What I claim is:

1. A fasten-ing device for wall boards, tiles and the like having penetrable edges, said device including a base, a web portion disposed at an angle to the base, and prongs projecting from opposite sides of said web adapted to. respectively penetrate adjacent edges of neighboring boards,`at least one of said prongs extending obliquely from the web and having angularly disposed side edges each inclined in the,l same general direction with respect to the web.

2. A fastening device for wall boards, tiles and the like having penetrable edges, said device including a base, a web portion disposed at an angle to the base, and prongs projecting from opposite sides of said web adapted to respectively penetrate adjacent edges of neighboring boards, at least one of said prongs having angu` iarly disposed side edges located on the same side of the normal to the plane of the web passing through the vertex of the angle formed between said edges. v

3. A fastening device for wall boards, tiles and the like having penetrable edges, said device including a base, a web portion disposed at an angle to the base, and prongs projecting from opposite sides of said web adapted to respectively penetrate adjacent edges of neighboring boards. at leastA one of said prongs extending obliquely with respect tothe web and having its outer end offset fnom its inner end in the direction of length of the web.

4. A fastening device for wail boards, tiles and the like havingv penetrable edges, said device including a base. a web portion disposed at an angle to the base, and prongs projecting from opposite sides of said web adapted .to respectively penetrate adjacent edges of neighboring boards, at least one of said prongs extending at an angle of `approximately 45 to the web.

5. A fastening device for wall boards, tiles and the like having penetrable edges, said device including a base, a web portion disposed at an angle to the base, and prongs projecting from opposite sides of said web adapted to respectively penetrate adjacent edges of neighboring boards, at least one of said pron s being of substantially triangular shape and h ving side edges defining an angle whose bisector is disposed at an angle of approximately 45 to the web.

6. A fastening device for wail boards, tiles and the like having penetrable edges, said device including a base, a web portion disposed at an angle to the base, and divergent prongs projecting obliquely from opposite sides of said web, said prongs being adapted to respectively penetrate adjacent side edges of neighboring boards.

7. A fastening device for wall boards, tiles and the like having penetrable edges, said device including a base, a web portion disposed at an angle to the base, and prongs extending obliquely from oppositev sides of the weband forming therewith substantially equal angles facing in the same direction, said prongs being adapted to respectively penetrate adjacent edges of neighboring boards.

8. A fastening device for wall boards, tiles and the like having penetrable edges, said device comprising two oppositely disposed substantially channel-shaped portions. each of said portions including a base, a web, and an obliquely extending prong adapted to penetrate a side edge of a wall board, the webs o'f said channel-shaped portions being disposed in the same planevand constituting continuations of each other.
