01 DALLAS, TEXAS I MEAivs Eon SUSPENDING WALL BOARD Application'filed m 1,

This invention has for its object to provide a new and improved means for suspending wall board, preparatory to depositing plaster thereon in the construction of plastic '5 walls. r

The present invention has relation to ap plicantscopending application filed April 13, 1929, Serial No. 354,7 98, for Plaster construction, and a similar application filed April 18, 1929, Serial No. 356,229, for means for hanging wall board. a

In this present invention a new and improved nail or fastening element is provided for supporting the wall board in spaced rela- 5 tion to the studding wherein the nail is driven. There is also provided means on the nail whereby a cushion is formed for the purpose of enabling the wall board to move slightly in taking care of any expansion, contraction or shrinkage which causes the plaster to crack.

The invention will be better and more clearly understood from a perusal of the fol lowing detailed description, taken in connection with the accompanying drawings formingpart of this specification and wherein:

Figure 1 is a fragmentary detail view in side elevation of a plaster wall construction and embodying the invention,

Figure 2 is a vertical detail sectional view taken along line 22 of Figure 3,

sition, with the plug and nail shown also in broken lines,

Figure 12 is a side view of the nail, plug and cover, the cover closed over the nail ready for application, and

Figure 13 is a vertical sectional view through the cover and plug shown in Fig ure 12.

Having a more detailed reference to the drawings, 1 denotes wall boards or panels of conventional size, held in position by a channeled webbing 2 ormetallic plate which form the subject matter of one of applicants applications previously referred to. The channel 3 separates the boards 1, the boards being vplaced behind the flanges or wings 4 and spaced from the studding 5 as clearly shown in Figure 2.

The particular object of the present invention resides in the fastening element or nail. This may bean ordinary wire nail 6 or any nail having a head such as is indicated at 7.

The nail 6 isembe'dded in a block of rubber 8, the block of rubber having a recess 9 open at the top. The preferred form of construction is that the nail be embedded in the rubber with the head of the nail abutting the bottom'of the recess. However, if preferred the rubber plugs or blocks may be channeled to receive the shank of the nail or the nail may be driven through the rubber when the two parts are connected to the studding.

The rubber plug or block is provided with a metallic cover 10 of oblong shape, including integrally formed wings 11. These wings as clearly shown in Figure 4 are bent at right angles to the cover and grip the sides of the block, holding the cover over the recess 9.

The block extends about midway of the shank of the nail and when in operative position abuts the studding 5.

The objectof the rubber block or plug in combination with the nail is to provide a cushion to obviate cracking of the plaster 12 in case of shrinkage, contraction or expansion of the woodwork. The wall board being spaced apart at 14 from the studding, is suspended or supported entirely upon the nail and plug. The recess being closed by the cover 10 no plaster can touch the nail, hence the plug or block 8 forms a substantial and effective cushion or resilient medium to relieve any sagging or the like which cause cracking of the plaster.

In Figure 6 is illustrated a modified form of covering and in this arrangement the covering consists of an oblong strip of metal 16, the end portions 17 being bent at right angles to the strip so as to tightly grip the block or plug 8.

A further modification of the nut is shown in Figures 10 to 13 inclusive. In this form a hollow steel ball consisting of an upper portion 20 and a lower portion 21 is provided. The upper and lower portions include an annular rim 22, the portions being separated up to the point A, which forms in effect a hinge. The lower portion has an opening B for passage of the nail 6. Beneath the ball and surrounding the nail is a rubber plug or block 8. Figures 12 and 13 illustrate the assembled parts and position of the nail head 7 when applying the latter to hang and suspend the boards.

In the operation of attaching the channeled webbing and nail and block in position to sup port the wall board, the nail is driven into the studding .5 by striking the covers 10 or 16 with a hammer or similar tool until the lower end of the plug abuts the studding. hen the cover is thus struck it will be de pressed to the broken-line position 18, due to the contraction of the rubber. The cover, however, will come in contact with the head of the nail and drive the latter home. After the final blow of the hammer the cover will rebound to the full-line position which brings it flat upon the metallic webbingQ. The plastering may then be placed to complete the wall.

The same procedure is carried out in attaching the form shown in Figure 6, except that the cover 16 is in proper position when flush with the surface of the webbing.

IVith reference to the last modification, Figures 8 to 13 inclusive, the upper portion 20 of the ball is bent over the nail head at the hinge A to the position shown in Figures 12 and 13 and the nail driven home. The hammer or tool upon striking the top portion 20 will depress the latter, and force the nail into the woodwork. The top portion 20 being of spring steel will rebound at successive strokes of the two, thus leaving the nail head 7 spaced from the inside surface of the ball. This prevents any plaster from touching the nail head and permits the latter to move freely to relieve expansion, contraction or shrinkage of the woodwork. The rubber plug 8 likewise forms a cushion to prevent cracking of the plaster.

lVhat is claimed as new is:

1. Means for supporting wall board in constructing plastic walls, comprising an elongated pointed element with an enlarged upper end; a rubber plug on the element, means for covering the enlarged end of the element to prevent contact with plaster, and means for attaching the covering means to the element.

2. In combination, means for suspending and supporting wall board and spacing same from the woodwork in constructing plastic walls, comprising a nail, a plug of resilient material on the nail body and providing a cushion, a covering for the upper end of the nail, said covering permitting the upper end of the nail to be normally free from contact with the covering to allow the upper end of the nail to move freely in the covering.

3. Means for supporting wall board as claimed in claim 2, said covering including means for insertion of the nail, the covering when struck by a tool springing back to normal position.

4. Means for supporting wall board in construeting plastic walls, comprising a nail, a rubber plug and a metallic hollow ball; said ball enclosing the head of the nail, the plug engaging the body of the nail; the head of the nail spaced from the inner walls of the ball; the ball preventing contact of plaster with vthe head of the nail, thereby preventing crackingof the plaster.

In testimony whereof I aflix my signature.

HENRY R. SHANKS.
