UNITED STATES LEWIS DANIEL, OF NEWPORT,

KENTUCKY, ASSIGNOR TO CLARENCE J. RENNEKAMP, OF CINCINNATI, OHIO. i

CAIPED NAIL AND TACK.

Application filed November 21, 1921. Serial No. 516,613.

;- To all'whom'it may concern: a

Be it known that I, Lnwrs DANIEL, a citizen of the United States,.and a resident of Newport, in the county of Campbell and State of Kentucky, have invented certain .-.new and useful Improvements in Capped Nails and Tacks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to nails and tacks which have secured thereon caps or button heads, which nails and tacks are used in various instances where it is desired to providea button for a fastener, or the like.

It is'the object of my invention toprovide such an article which can be inexpensively manufactured, and which possesses the desired characteristics of appearance and strength necessary for a marketable product of the nature set forth.

In the manufacture of special heads, such asbuttons and the like for nails, the manufacturing cost enters very largely into consideration. In the past, to place a suitable button on the end of a nail or tack required operations of trimming and drilling, which required'special manipulation of the small piecesinaking' up the completed article, and while this could be automatically done in large part, it required expensive machinery and considerably more time for each piece than was truly economical.

According to my invention, the pieces used are stamped out and without trimming,

dropped onto the usual headed tack or nail ofcommerce and clamped into place.

. These. objects I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed, wherein a very economical manufacturing process may be employed.

In the drawings,

a Figure 1 is a side elevationof a' completed button headed tack.

Figure 2 is a like view of the tackbefore the cap is placed thereon.

Figure 3 is a perspective view of the sim plest form of bell used in making the cap. Figure 4. is a perspective view of the top i piece of the cap.

Figure 9 is a perspective View of the parts of a third form of nail.

Figure 10 is a central longitudinal section through the parts shown in Figure 1.

Referring first to the simpler form of capped tack, it will be noted that I employ the tack lhaving the usual head 2, which as in the usual form of tack is formed by a die opelpation on the piece of wire forming the tac Such tacks are the usual article of coinmerce and purchasable at alow price or readily manufactured by fully automatic machinery, at a high rate of speed.

I provide a metal stamping having a belllike shape as at 3, and split lips 4 at the expanded end, with the apex of the bell formed with a hole 5 to slip over the shank of the tack. I also provide a top piece of fiat body 6 and a flange 7, which in the original piece extends downwardly from the body.

In assembling the article, the tack is dropped into the bell on a suitable multiple unit machine with the head lying within the bell, which is of a size at the base of the lips to snugly receive it. The top piece is then dropped onto the assembly and pressed down and the flange turned under,which forces the head of the tack firmly into the seat of the bell and engages the head around the lips of the bell, drawing said lips to gether snugly around the head of the tack.

The article is then complete, except for enameling, if desired, and there are no parts 'to' be injured by baking the articles after dipping in enamel.

The entire button thus formed is quite low and perfectly tight, and hammer blows on the top piece will not injure the assembly as the head ofthe tack itself receives these blows and relieves the bell of any strain.

There are no parts to be trimmed or smoothed off, as the only edges exposed are formed by bending the metal of the top piece and bell, around their respective forms.

In m flikingthe double button head for a nail or tack, I employ a nail having a shank 8 and head 9, same being again a cheap article of commerce. I then form a double bell having a body 10 and lips 11, 11, at each end, which turn outwardly from the tubular or body ortion of the double bell.

I a so provide two end pieces similar to the one top piece of the first modification, as at 12 andl3, the end piece 12 having a hole therein to sli over the shank of the nail.

In assemb ing the article, the bell and the lower end piece 12 are first placed together and the end piece crimped over the lips of the bell by folding inwardly the flange 12 thereof. The nail is then dropped into theother end of the hell with the shank passing through the hole in the piece 12.

The top piece 13 is then dropped on and driven down'and the flange folded in as at 13. The head'of the nail is thus firmly seated in the upper end of the bell where the lips start to swell and. the folding or crimping in of the flange of the to holds the lips firmly around the hea Here again the head of the nail takes the'blows necessary for driving down the piece article and there is no trimming of parts necessary to effect a finished article of great strength and perfect smoothness at all exposed or working surfaces.

In addition to the double bell formation in making up the ca ped nail, I may also proceed as follows: igure 9) The nail 14 with the head 15 is used as in the second instance, and the bell or fitting has a tubular body 16 with lips 17 at the lower end, but cylindrical or substantially so at 1 the top. The cap 18, similar to the caps already described, is crimped over the head of the nail with its inner edge not quite meeting the nail shank below the head.

The lower cap 19, similar to the piece 12,

is crimped over the lips 17 and the nail forced down through'the body 16, and the hole in the cap 19. This willforce the upper edgeof the body 16 into the space between the flange and head of the cap 18 tubular body and the cap 18 are arranged of the head of the-tack or nail used, and" so that the forcing of the nail downwardly into the said body will make the tight .fit

last above noted. v p

It is obvious that by confining the size likewise controlling the size of the body portion of the bell as'distinguished from ton thereon, comprisin tubular body, and'a bell-shaped crest, with the lips thereof, I can make up a capped nail or tack with the desired amount of depth from the shoulder formed on the shank of the nail to the top of the cap or button.

Having thus described my invention,

the split edges 01 said first mentioned piece.

2. In combination with a headed tack or nail or the like, a piece havin a body por tion oit tubular nature expand ed at the/up per end to form a seat for the head of said tack or nail, with a portion of the piece ex tending below said seat to form the shank of a button, and a top piece having a flange thereon, said piece being adapted to engage over the head of said tack'or nail, with the flange bent inwardly around itto engage the expanded edges "of the first mentioned piece.-

3. In combination with a headed tack or nail or the'like, a means for forming a but a piece having a the lips :l'orming said bell-shapedorest re viding a seat for the head of the nai or tack, and a top piece shaped to fit smoothly over the said head andhaving a flange adapted to engage over the said lips and a clamp said first mentioned piece firmly in position, as and for the purpose described.

4. In combination with a headed tack or nail or the like, a means for forminga double headed button thereon, comprising a piece having a tubular body, and a cap secured thereon at its lower edge with said;

body formed out to form a seat for the head of the nail or tack, andadapted. to slide into position over the shank of the same, and a top cap adapted to engage over the head of the tack and firmly engage over the formed-out portion of the first mentioned piece. '3

5. In combination with a headed-tack or nail or the like, a meansior forminga double headed button thereon, comprising a tubular piece having expanded upperland lower edges, said expanded edges being split to form lips, an apertured'cap adapted to slide over the shank. of thetack or nail, said cap being provided with a ufiange turned inwardly over thelower expanded edges oit'the above mentioned iece,-aiid another cap adapted to fit over't ahead of the tack or nail and having a fiange adapted to be turnedinwardly beneath the' head,

and over the upperexpanded edgesofthe i a I30 first mentioned piece.

6. In combination with aheaded tack or head thereof, and-a top cap adapted to ennailror the like, a means for forming a gage over the head of the nail having a double headed button thereon, comprisinga flange formed inwardly under the head and 10 piecehaving a tubular body and cap seengaging over the upper end of the tubular 5 cured thereon at its lower edge, with said body.

body adapted to slide into position over the v shank of the nail and abut the sides of the LEWIS DANIEL.
