PREFACE.

Vol. I. of this series was devoted to a consideration of the early history of blacksmithing, together with shop plans and improved methods of constructing chimneys and forges.

Vol. II. was, for the most part, given up to a consideration of tools, a great variety of which were described and illustrated.

In Vol. III. the subject of tools is continued in the first and second chapters, after which the volume is devoted chiefly to a description of a great variety of jobs of work.

In the present volume we have continued the very interesting topic of jobs of work, and have devoted considerable space to the subjects of cutting, bending, welding and setting of tires, setting axles, resetting old springs, making bob sleds, the tempering of tools; bolts, nuts, the working and welding of steel, etc. The last chapter is wholly given up to the compilation of a set of tables giving the sizes and weights of iron and steel.

CHAPTER I.

Miscellaneous Carriage Irons.

The blacksmith is often called upon to repair carriages and wagons, or to iron some particular part of each on short notice, and unless experienced in carriage work much valuable time is lost in devising means of performing the work in a satisfactory manner. As a help to such the directions in this chapter for making a variety of irons will be found valuable.

As hammer signals are of interest we preface this chapter with a complete code.

Hammer Signals.

When the blacksmith gives the anvil quick, light blows it is a signal to the helper to use the sledge or to strike quicker.

The force of the blows given by the blacksmith’s hammer indicates the force of blow it is required to give the sledge.

The blacksmith’s helper is supposed to strike the work in the middle of the width of the anvil, and when this requires to be varied the blacksmith indicates where the sledge blows are to fall by touching the required spot with his hand hammer.

If the sledge is required to have a lateral motion while descending, the blacksmith indicates the same to the helper by delivering hand-hammer blows in which the hand hammer moves in the direction required for the sledge to move.

If the blacksmith delivers a heavy blow upon the work and an intermediate light blow on the anvil, it denotes that heavy sledge blows are required.

If there are two or more helpers the blacksmith strikes a blow between each helper’s sledge-hammer blow, the object being to merely denote where the sledge blows are to fall.

When the blacksmith desires the sledge blows to cease he lets the hand-hammer head fall upon the anvil and continue its rebound upon the same until it ceases.

Thus the movements of the hand hammer constitute signals to the helper, and what appear desultory blows to the common observer constitute the method of communication between the blacksmith and his helper.

Making a Thill Coupling.

My way of making a thill coupling is as follows:

I take a piece of Norway iron, say, for a buggy, three-eighths of an inch by two and one-half inches, then cut off a square block and cut it in the way shown in Fig. 1 of the accompanying illustrations, and in which A A denote where the blot goes through.

B is drawn down and rounded for the lower part of the front side, as shown in Fig. 2. C is drawn out to make the cuff which goes over the axle and down on the inside.

Fig. 2—Showing the Coupling Completed.

I find this plan better than depending on welding the lugs A A to the other part. —By J. A. R.

Making a Thill Cuff.

To make a thill cuff or shackle, take a piece of iron three inches wide and three inches long by five-sixteenths of an inch thick, and fuller it as shown in Fig. 3.

E. W.’s Method of Making a Thill Cuff.

Fig. 3—Showing How the Iron is Fullered.

I then bend up two comers to which the shaft end is to be fastened, and drill holes through for bolts, as in Fig. 4.

Fig. 4—Showing How the Piece is Bent and Chilled.

Fig. 5—Showing the Thill Cuff Completed.

One of the other ends is drawn out for the clip, with an end shaped for a nut. The other end is also threaded for a nut. The thill cuff is then finished, as shown in Fig. 5. It should be made of the best iron, either Norway or Sligo. —By E. W.

Making Spring and Axle Clips and Plates.

As most blacksmiths will be interested in learning a good method of making spring axle clips and plates, I will, with the aid of the accompanying engravings, endeavor to show how the job is performed in my shop.

Fig. 7—Showing the Finished Clip Plate.

Fig. 6 represents the clip. A indicates where the axle sets, and B B are parts of the clip plate. Fig. 7 shows the finished clip plate. The part C sets on the spring. E is the space between the cars, D D, in which the clip shown in Fig. 6 fits.

Fig. 8 represents the whole thing put together. A is the spring plate, F is the axle clip, C C are the spaces between the clip yokes.

Fig. 11—Showing How the Fullering is Done.

In making, first bend the ends at HH in Fig. 9, in which K indicates the plate, then split down as at M in Fig. 10, next fuller in with a small fuller as at M in Fig. 11, and then using a larger fuller bring to the shape shown in Fig. 12.

If the best iron is used the bending can be done with one heat, and another will be sufficient for the working out If ordinary iron is employed more heats will be required. —By Iron Doctor.

How to Prevent Working of King Bolt, and How to Make a King-bolt Stay.

All carriagemakers have had more or less bother with the head of the king bolt becoming loose in the head block, rattling, turning around and finally making a hole in the block. After some study and experimenting I have overcome the trouble. I have also managed to get up a first-rate king-bolt stay, which will wear a long time without rattling, and does not wear a hole in the king bolt or wear the thread off.

In Fig. 13 I show how I take care of the king bolt. A is the oblong or elongated head which is let in the head block, C is the king bolt or a section of the same. BB are holes in the head which I countersink from the upper side, and put in two five-sixteenths inch bolts which go all the way through the head block and head-block plate and fasten with nuts on the under side. Since making my king bolts this way I have had no more trouble.

How to Prevent Working of King Bolt. Fig. 13—Showing How the King Bolt is Made.

By Fig. 14 I show how I make the king-bolt stay. B is the head, with the hole E for the passage of the king bolt.

Fig. 14—Showing How the King-bolt Stay is Made.

F is the stay, which may be made flat, oval or round. I always make mine oval. By G I show a recess in the under side of the nut—done by counterboring—for the insertion of the king-bolt nut, which is so made as to fill the recess which I show by Fig. 15. K is the square part of the nut on which the wrench is placed. I sometimes make them six-cornered. H is a raised round section on the nut which fits in the recess in the stay head at G. The wear by this means comes on the nut and not on the king bolt.

Fig. 15—Showing the King-bolt Nut.

I make an ordinary nut and form the round part with a file. In conclusion, I think I have wrought out something good which all may use. —By Iron Doctor.

Fastening a King-bolt Stay.

It took me a good many years to learn that if I bolted iron to iron where there was much vibration the bolts would soon break. For years I bolted my king-bolt stays to the reach or reaches with, as I thought, bolts strong enough to hold. Well, they would hold a little while and then the nuts would get loose and drop off, sometimes the reach would split and refuse to hold a bolt. After putting up with the nonsense about long enough, I put on my thinking cap and turned out a pretty reliable stay, which I have been using ever since. It is a simple but effective stay. A, Fig. 16, is the back end, which extends under the reach enough to take one or two bolts. B B are ears on each side of the plate and form a good solid clip bar.

Fig. 16—Fastening a King-bolt Stay as Made by Iron Doctor.

C is a section of the stay neck. I make a wide clip (two inches wide), and secure the perch and stay with the same, and have no further trouble. —By Iron Doctor.

A Good Spring Doubletree.

I send you a spring doubletree (Fig. 17) which I think is much simpler than any other I have ever seen. Any blacksmith can make it. The spring is ten inches long by one and three-fourths inches wide, and made with two leaves. The spring stands off from the end of the doubletree two and one-half inches. Two bolts are sufficient to make secure.

Fig. 17—Showing the Spring Doubletree Described by J. O. Hess.

This will do for ordinary farm work; for heavy work it should be made stronger.

One of these springs will pay for itself in less than a year in easing the wear and strain to horse, harness and wagon. —By J. O. Hess.

Making a Pole Cap or Tongue Iron.

To make a pole cap or tongue iron, take two pieces of band iron, fifteen inches long and one and one-fourth by three-sixteenths of an inch, and a piece of rod iron eleven inches long by five-eighths of an inch in diameter, and weld the rod to one of the flat pieces, as shown in Fig. 18 of the accompanying illustrations.

Fig. 21—Showing Pole Cap Completed.

Then shape them as shown in Fig. 19, weld on the other piece of band iron as in Fig. 20, and bend to shape as shown in Fig. 21. Then the bolt holes are drilled, and the job is completed. —By J. M. W.

Making a Prop Brace for a Carriage.

To replace a prop brace for a carriage I use oval iron of right size, upset the ends, and bend one end as shown in Fig. 22. I next take a key-hole punch and punch a hole as at A in Fig. 22. I then open up the hole with a small round punch.

Earnest’s Method of Making a Prop Brace. Fig. 22—Showing How the End of the Piece is Bent.

I next proceed to make an end or stock for a joint by forging a piece of iron so as to make it seven-sixteenths of an inch by eleven-sixteenths of an inch, and then bend the end as at C, Fig. 22. I then make a square-lipped drill with a centerpiece one-fourth of an inch round, as shown in Fig. 23, the lip being as broad as I want the joint to be.

Fig. 23—The Drill.

I next drill a hole three-fourths of an inch in diameter through the end, as shown in Fig. 24, and with the square-lipped drill make a hole half way through the end, as shown by the dotted lines in Fig. 24.

Fig. 24—Showing the Position of the Hole when Drilled.

I next file off the edges, all that the square-lipped drill had left. I file three-fourths of the way down, and file around, beginning at E and ending at B, Fig. 24, leaving the piece as shown in Fig, 25.

Fig. 25—Showing the Piece Ready for Welding.

I then weld the piece Fig. 25 to the part shown in Fig. 22, F being welded to D.

Fig. 26—Showing the Brace Completed.

I next make another piece just like the first I have described, put the two together with a large head-rivet, and this makes the job complete, as shown in Fig. 26. —By Earnest.

Making a Pole Socket.

I will describe my way of making a pole socket:

Take a piece of Norway iron at least three inches wide and three-eighths of an inch thick, cut it to the length of four inches, and mark it off with a pencil as shown in Fig. 27.

Fig. 27—Showing How the Iron is Marked.

Then mark the pencil lines with a cold chisel, heat the piece and cut it out. Next bend the part A down at B over the anvil and work the corner up square. Do not use the vise in bending, for it is a mistake to bend any sharp corner in a vise.

Fig. 28—Showing the Piece After the Rounding and Welding Operations.

Then draw out the part B, leaving it one-half inch or two inches wide and three-sixths of an inch thick. Next bend it round to a diameter of one and one-half inches, then weld, finishing and rounding it upon a mandrel, and it will then be of the shape shown in Fig. 28.

Fig. 29—Showing How the Piece is Split, Bent and Formed.

Next punch a very small hole at C, split it upward as shown by the dotted line, and bend and form each half as in Fig. 29. My boss had another way of making a socket.

Fig. 30—Showing How the Ears are Welded in Another Way of Making a Pole Socket.

Fig. 31—Showing the Ears as Welded On.

He took a piece 1 3/4 x 5-16, and welded on the two ears shown in Fig. 30, A A being the ears and BB the scarf ends to weld on. When the welding was done as shown in Fig. 31, he did the bending and other work in the same way that I do. —By T. J. B.

Making a Staple and Ring for a Neck Yoke.

Many years ago, when I worked as a journeyman in a carriage and wagon shop, I often thought when ironing neck yokes,
