NAPOLEON B. REYNOLDS, OF AUBURN, NEW YORK. Lara-8 Para@ No. 65,604, dated .me 11, i867.

TO ALL WHOM IT MAY CONGERN:

Be it known `that I, NAPQLEQN B. REYNoLDs, of Auburn, .in the lcounty of Cayuga, amd State of New lYork, have invented certainV new and useful improvements -in `the Manner of Making-or Forming thePr'ojection or Swell on' the Cap of Plane-Irons, and which is used instead of a'loose nut for holding the Screw-bolt that secures the cap to the plane-iron; and that the following is a full', clear, and exact description of the manner of doing the same, reference being had to the accompanying drawings, making a part of this specification, in which- V Figure I represents a view froin the back of theplane-iron, showing the slot the-rein and the bolt passing through it into the cap. i ,i *i i l I I Figure 2 representsni cap with a hole punched throughit for the reception of the button which afterwards forms the swell, projection, or ruit for the `screw-bolt to take into.

Figure 3 represents a section. through the' cap, and showing the countersinking of the hole that'is to receive the button.

Figure 4 represents a section through the cap after the button or swell is fastened thereto.

Figures 5 and 6 show'a top and edge view of one of the buttons before it is inserted in the hole in the cap.

Figure 7 shows thev form of the swell, button, projection,` or nut after it has beenxriveted in the hole in the cap. I

Similar letters of reference, where they occur in the several separate figures, denotelke parts in all the drawings.

Iam aware that a swellsor projection has been proposed on the cap of a plane-iron as a substitute for the ordinary loose nut heretofore used. I do not claim the swell or projection. My invention consists. in the manner ormeans of producingrthis projection, which I do in a very cheap and very durable manner, without rolling down the metal or heat-welding it. i

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings. V

At manufacturing establishments where boilers are made are to be foundand procured at very cheap rates, and of the -very finest quality of iron, any quantity of burrs or buttons that are punched out of the plates of which the'boilers ar-e made for inaking rivet holes. These hurrs or buttons .can be procured at a rate but little above that of old'iron, and are therefore very cheap, Whilst they have the form, body, and flange or n that peculiarly it's them for my purpose.

The cap A I propose to make of steel, and a hole, a, having been punched through, it is then countersnnk o1' re'amed out at each sidevof the plate or cap, as shown more distinctly in fig. 3. I then take one of the bui-rs or buttons b andinsert it in the hole a in the cap. The iin or ange c which is on the burr or but-ton, and left there by the punch that drove it ont of the boiler-plate, fits into the countersink on one side of the hole, and the burr or button projects through and beyond the other face of the cap. In this position the cap and burr are placed under va dropadie, one blow of'w'hichrivets the button or burr in the'hole, and it is afterwards dressed up to the proper shape or form for Aentering the slot in the plane-iron, and for preventing the cap from turning on the plane-iron, whilst it can move longitudinally of it. When -the riveting on of the button is accomplished, as explained, the burr or button will have assumed the form shown at iig. 7, and also in fig. 4, and be as immovably xed thereto as though it were a part of the same metal with the cap itself.

As amatter of economy I should valways use the burrs or buttons made by punching boiler-plates, yet I would regard it asmy invention if these burrs were especially punched out for the purpose herein named.

i Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent in forming a swellor projection on the cap of a planeiron, is'

The method of construction substantially as descriled.v
