TREE-NAIL MACHINE.

ASpecification of Letters Patent No. 12,909, dated May 2.2, 1855.

T0 all whom it may concern:

Be it known that I, I. IV. HOAGLAND, of Jersey City, county of Hudson, and State of New Jersey, have invented a new and useful Improvement in the Machine for Making Tree-Fails; and I hereby declare that the following is a full and exact description.

To enable others to make and use my invention I proceed to describe its construct-ion and operation, reference being had to the drawings hereunto annexed'and making part of this specification.

Figure 1, elevation of the inner headfront end; Fig.y2, stanchions for feed rollers-side view; Fig. 3, rear head elevation; Fig. 4, side elevation of the machine; Fig. 5, the casting of the inner head; Fig. 6, section of the same; Fig. 7, the boxes for the journals; Fig. 8, the rack and pinion apparatus; Fig. 9, the follower, wit-h sections of shaft; Fig. 10, plan of a portion of the machine, showing the follower, H, in position; Fig. 11, one of the cutters; Fig. 12, the box for heading or pointing the treenail--rear end; Fig. 13, front of the box; Fig. 14, side elevation of it; Fig. 15, longitudinal sectiony showing the screw at the bottom of the opening by which the pointing or heading is gaged.

The machine as shown in the drawings is -set upon a frame or bench so as to bring it to a convenient height, and may be driven by a one horse power. The head pieces and other stanchions are of cast iron and the shafts of wrought iron.

supposing the machine intended to form an Octagon treenail there will be eight shaftsa as shown in the side elevation and marked These are all connected by cog wheels. The driving pulley is upon one of these eight shafts at the rear end of the machine, Fig. 4.

The bolt or stick of which the treenail, (X), is to be made is entered between the two feeding rollers (see Fig. 1) which are set front of and outside the cutters. The stick-is acted on by the cutters and shaped at its end and thus received by the second pair of feeding rollers (see Fig. t). These are held with considerable pressure upon the treenail'. The pressure is however gaged and governed by the oval button (b and R) Fig. 2 and this is moved and governed by the levers The front head (A) in which the shafts of the cutters run isabout fifteen inches in diameter, of a circular form and about two inches thick. In the rear side of this casting depressions are left in which sit the turned true, about half an inch in diaineter.

This protrudes through the slot in the circular plate D. The circular plate is wrought iron about three eighths of an inch thick and the rim two inches wide. This circular plate has bolted to it, two arms or levers (D). The rear side of the head is turned out so that the circular plate will fit into it snug and yet admit of its turning a little.

Upon the side of the machine is a wheel, J, about eight inches in diameter, having pins or cogs upon its periphery on which runs a chain band (w) to which a weight is att-ached. Upon the same shaft is a small pinion, K, working into a horizontal rack which lies upon it. Upon this rack, T, is laid the gage or pattern formof the tree* nail, cut from a strip or iron, and marked U. In the center of the machine is a rod, on the forward end of which is a circular disk, called the follower (I-I) which is supported by projecting arms upon a track or way, Z, upon each side of the machine. Upon the rod is an arm to which the chain band is attached-so that when the follower is thrust back by the treenail striking against it, it will turn the wheel (J) over which it runs and when the treenail drops the weight will .draw the follower back again toward the head of the machine.

Upon one of the arms D is screwed a 'perpendicular stem (Y) with a slot at its fastening so that it can be graduated. At the bottom of the stem is an anti-friction roller and this rests upon the pattern, U,

hinged upon a cross piece on the stanchion see Fig. (2) and upon the inner side of it is screwed a lever (R) which rests against the arm D of the circular plate and is governed by its motion. There is an oval button, b, on each side, and the lever attached is, on one side, placed above the arm D of the circular plate and on the other side beneath it. lVhen'the gage or pattern causes a mot-ion of the arm of the circular plate it moves also the levers R upon the oval button and these force apart the boxes of the feed roller shaft and the spiral springs force them together again. Thus accommodating the opening of the feed rollers to the varying size of the treenail.

The feed rollers are driven by a pinion P upon the top shaft about three inches diameter. This meshes in a ten or twelve inch cog wheel O, upon a shaft, N, running to the forward end, where it has a small bevel pinion worked in a large one M which is on the upper feed roller shaft. The two pairs of feed rollers are connected by gearing, L.

I/Vhen the treenail is finished it is made to drop out by means of a treadle. In which I do not claim novelty and therefore it is not represented.

On the rear end of same two of the shafts I screw on collars in which there is, in each a conical hole, with knives set in and screwed fast like plane irons, having openings for the chips like the throat of a plane. This is for pointing and heading the tree` nails. One being made more flaring for the head and the other shaped for vthe point. While the machine is in operation and these shafts revolving with great rapidity. The treenails are received as they fall from the machine and the ends thrust in at these conical holes and thus instantly rounded at the head and sharpened at the point. This saves the treenail driven from the necessity of sharpening them with the broad axe as usual and the rounding of the head prevents its splitting when driven. See Figs. 12, 13, 14, and 15 for the heading and sharpening collar. A screw is set at the bottom to gage the depth at which the head or point shall be thrust in.

In the attachment of the cutters there is nothing new. They are screwed to the forward ends of the shafts. The formation of the cutter-see Fig, 11 is new. It is bent, as in .former machines, but then twisted or made diagonal, so that it will cut at an angle.

The improvements which I have made produce the following advantages. The gage U is moved by the follower IFI and that is moved by the tree nail which is in process of formation and the tree nail is made exactly to the pattern. The tree nail in my improvement is held firm by the feed rollers and does not shake. The button on the lever It, opens them to admit the tree nail as it is enlarged. The circular plate holds the boxes solid and by its movement gages the size of the tree nail-the arm, D, being raised or depressed by the pattern, U, passing back and forth. I head and point the tree nail as fast as made, and in this machine I do no-t require to shave the bolt or stick, but enter it in the rough and make a perfect tree nail at one operation.

What I claim as my invention and desire to secure by Letters Patent is:

1. The use and employment of the circular plate (B) with its diagonal slots (a) to concentrate or expand the cutters and thus regulate the size of the tree nail in the manner above described.

2. The use and employment of the follower (I-I) with its apparatus of band and wheel to govern the gage, U, so that the tree nails may be made uniform in size; arranged and constructed substantially as above described.

3. The use of the levers and their apparatus of ovals (5,) to separate thev feed rollers or allow them to approach each other, for the purpose of holding the tree nail firmly, while it is being enlarged or diminished, in the manner above shown.

4.. The use of the pattern gage (U) and the stem (Y,) to govern the circular plate.
