Hammer (musical instrument)

“ It gives the tuner a much more favorable position at the instrument; and, as the right hand is more used in ordinary every-day operations and is more trained in applying degrees of force and guiding tools, it is more easily trained to manipulate the hammer properly. Training the hand in the skilful use of the hammer is of the utmost importance and comes only by continued practice, but when it is trained, one can virtually "feel" the tones with the hammer. ”

“ The sound of a pianoforte is produced by hammers. In this the pianoforte resembles the dulcimer, from which we may regard it as developed by contrivance of keys and intermediate mechanism, rendering the pianoforte a sensitive instrument of touch, instead of one of mere percussion, incapable of refinement or expression. The pianoforte hammer consists of head and shank like any other hammer ”

“ HAMMER-THROWING, a branch of field athletics which consists of hurling to the greatest possible distance an instrument with a heavy head and slender handle called the hammer. Throwing the hammer is in all probability of Keltic origin, as it has been popular in Ireland and Scotland for many centuries. ”

“ The material of which this axe-hammer is made appears to be serpentine. It was found in the Thames, at London, and is in the British Museum. A "hammer" from a barrow at Wilsford, [129] Wilts, which was associated with a flat bronze celt and other articles of bronze, was of the same type as Fig. 142, but without the grooves.
The very neatly formed instrument represented in Fig. 143, seems to occupy an intermediate place between a battle-axe and a mace or fighting hammer. It is rounded in both directions at the butt-end,
Fig. ”

“ Simple as the finished hammer looks, there are a hundred and fifty years of thought and experiment in it. It required half a century to exhaust the different kinds of wood, bone, and cork; and when, about 1760, the idea was conceived of covering the hammers with something soft, another century was to elapse before all the leathers and fabrics had been tried, and felt found to be the ne plus ultra. With regard to the action, or the mechanism by which the hammers are made to strike the strings, we must refer the inquisitive reader to the piano itself. ”

“ It would seem possible that the greater rebound of the hammer which would be the consequence of a sharp blow upon the key might render the actual contact with the string shorter, while the greater force of the blow might compress and so slightly harden the soft surface of the felt with which the hammer is covered ”

“ Hammers, when made of felt, will of course require the same treatment as those in the upright. In many old squares the hammers are built up of buckskin. If this becomes beaten down hard, it is well to cap the hammer with a new soft piece of buckskin, gluing only at the back ends. ”

“ His hammer is a tool of immense power and pliancy, but for which we must have stopped short in many of those gigantic engineering works which are among the marvels of the age we live in. It possesses so much precision and delicacy that it will chip the end of an egg resting in a glass on the anvil without breaking it, while it delivers a blow of ten tons with such a force as to be felt shaking the parish. ”

“ When the bushing of the center-pin of the hammer butt becomes badly worn or the hammer-flange becomes loose, or the condition of the hammer or flange becomes so impaired that the hammer has too much play, it may so strike the strings as to tend to produce the phenomenon described in the above paragraph. When in such a condition, one side of the hammer may strike in advance of the other just enough to throw the vibrations in opposition. Once you may get a strong tone, and again you strike with the same force and hear but a faint, almost inaudible sound. ”

“ The back check, hammer stem and regulating button are subject to the same faults as their counterparts in the upright, which may be remedied in the same way. Bridles and hammer springs are not needed in the square, as the weight of the hammer, moving in a vertical direction, is sufficient to bring it to its rest position. ”

“ In such cases, the workmen acquire great skill and expedition in the manufacture. A tilt hammer is often used in forging large masses of iron, and even in making utensils as small as the hoe, the axe, and the sword; but the hammer which may be employed bears a due proportion in its weight to the mass of iron to be wrought. In all cases in which a tilt hammer is used, the bellows from which the blast proceeds is moved by water or steam power. ”

“ They give the greatest number of coats, and the thickest buckskin to the hammers for the bass strings, and then taper up evenly and truly to the treble hammers, which have a less number of coats and of the thinnest kinds; and then, after the hammer is fitted to the string in the piano, and it has been tuned and the action adjusted, it goes into the hands of the hammer finisher, who tries each note, and takes off and puts on different buckskin until every note is good, and the tone of the piano is perfectly true. ”

“ To get a rich tone we must keep as many useful harmonics as possible, and therefore a piano hammer is so placed as to strike the string at a point which does not interfere with the best harmonics, but kills those which are objectionable. Pianoforte makers have discovered by experiment that the most pleasing tone is excited when the point against which the hammer strikes is one-seventh to one-ninth of the length of the wire from one end. ”

“ The labor saved by this hammer is immense. One man sits perched up on the frame to direct it, and another stands below to guide the iron on the anvil. The great long bar, white with heat, is pulled out of the furnace, laid on the massive piece of iron under the frame, and, with a dull, heavy sound, down conies the hammer, swiftly or slowly, according to the wishes of the director. From the forge and the foundry the "rough-hewn" iron-work passes to be planed, and its surface to be made "true." ”

“ The inter-collegiate rules which govern the throwing of the hammer require that the hammer-head shall be a metal sphere; and the handle may be of any material. Up to within three or four years the handle used to be made of hard wood, but recently athletes have shown a preference for a flexible steel handle. The combined length of the head and handle must not exceed four feet, and the combined weight must be sixteen pounds. The hammer is thrown from a circle seven feet in diameter. ”

“ It is curious to see how the rudest of primitive weapons, after its serious warlike use has ceased, survives as a symbol of power, when the mace is carried as emblem of the royal authority, and is laid on the table during the sitting of Parliament or the Royal Society. While the club has been generally a weapon, the hammer has been generally an implement. Its history begins with the smooth heavy pebble held in the hand, such as African blacksmiths to this day forge their iron with, on another smooth stone as anvil. It was a great improvement to fasten the stone hammer on a handle ”

“ Simply because of their want of compass, of range and fall, as well as of their want of power of blow. A few moment's rapid thought satisfied me that it was by our rigidly adhering to the old traditional form of a smith's hand hammer— of which the forge and tilt hammer, although driven by water or steam power, were merely enlarged modifications—that the difficulty had arisen; as, whenever the largest forge hammer was tilted up to its full height, its range was so small that when a piece of work of considerable size was placed on the anvil, the hammer became "gagged;" ”

“ Some of them for the under coatings or layers are firm and yet elastic and soft, while those prepared for the top coating or capping are pliable and soft as silk velvet; and these, when correctly applied, will form a hammer which, if the piano-forte is perfect otherwise, will always give the rich, full organ tone for which the pianos of Messrs. Boardman & Gray are so celebrated. Those employed in covering and preparing hammers do this exclusively, and must perfect their work. ”

“ The movable-fulcrum power hammer was designed by the writer about five and a half years ago, to meet a want in the market for a power hammer which, while under the complete control of only one workman, could produce blows of varying forces without alteration in the rapidity with which they were given. It was also necessary that the vibration and shock of the hammer head should not be transmitted to the driving mechanism, and that the latter should be free from noise and liability to derangement. ”

“ The hammer is made of high-grade steel, carefully tempered head and peen; the head is usually made cylindrical with slightly rounding face; the eye of the hammer is the center opening through which the handle is inserted. The peen of a hammer is the opposite end to the face, and terminates in a rounded or wedge-shaped point. ”

“ Towards the end of the heathen period we find instead of the axe a symbolical hammer, alike on both sides of the eye. The fact that in Scandinavia the sun god's axe became a hammer can be explained, if we consider the original Scandinavian word hamarr. This word signified originally stone, and was thus a natural term for the weapon of the sun god or the thunder god, so long as this weapon was thought of as a thunderbolt of stone. Later on, when the word had acquired its present meaning of hammer, it was just as natural for people to imagine Thor's weapon to be an iron hammer. ”

“ By this we recognize the importance of the place of contact, or striking-place of the hammer against the string; and the necessity, in order to obtain good fundamental tone, which shall carry, of the note being started from a node.
If the hammer is hard, and impelled with force, the string breaks into shorter sections, and the discordant upper partials of the string, thus brought into prominence, make the tone harsh. If the hammer is soft, and the force employed is moderated, the harmonious partials of the longer sections strike the ear, and the tone is full and round. ”

“ The heaviest I possess weighs only five ounces, and the lightest less than half that weight. As will subsequently be seen, it is possible that some of these instruments were of the nature of anvils rather than of hammers, but for the present it will be most convenient to speak of them under the latter name.
The most common form of hammer is that which is shown in Fig. 210, from an original in the British Museum found at Thorndon, [630] Suffolk, in company with a spear-head, socketed gouge, socketed knife, and two socketed celts. ”

“ The hammer used to take out nails, is called a claw-hammer, from its having a claw at one part. The claw is placed under the head of the nail, when the handle of the hammer becomes a lever, and the head the fulcrum; and, placed in this position, the hand acquires great power,—sometimes amounting to at least a hundred-weight. In using a hammer, we should always be careful to use the kind of hammer necessary for the work to be done. ”

“ When using this form of enrichment, the stone should never appear to rise abruptly from the primary mass, but should be approached by a series of rising planes.
Planishing
9. The process of smoothing and, at the same time, hardening the surface of the metal with a steel planishing hammer. The hammer strokes give an interesting texture to the surface which may be varied, from the heavily indented to the smooth surface, at the will of the craftsman. The more obvious hammer strokes are not to be desired as they bring a tool process into too much prominence for good taste. ”

“ Axes with or without handles are carved on stones forming the walls and roofs of tombs of this period. The image of a man, or rather of a god, with an axe, may be seen on the wall of one of the caves that in Champagne are hewn out of the chalk-rock (Fig. 15) , and from the time that Gaul was a Roman province we have many reproductions of a god holding in his hand a hammer with a long handle (Fig. 16) . The hammer, symmetrical like the double-edged axe, strongly resembles the hammer of the northern Thor, but the handle is so long that it reaches the ground. ”

“ Of the understriking action, his 'Pianoforte,' he has given us full particulars and a drawing, here reproduced—
Fig. 3.
a is the string; c is the key; e, a second lever; g, a jack to raise the hammer; o, the hammer itself, clothed at the tail, r, to serve for a damper. The play, or space, between the jack and the hammer-shank permitted, as in the early square-paino action of Zumpe (which may have been partly derived from Schroeter's idea) , the rebound, or escapement, of the hammer. ”

“ As the constant hammering on the head of the flatter will also cause the head to become battered, it is good practice frequently to draw out the head and lay the flatter aside to cool. This will anneal the steel and prevent crystallization, at least for some time.
23. The square-and round-edged set hammers (B and C, Fig. 10) are employed for various purposes. The former is used for making square shoulders or depressions such as could not be produced with the hand hammer alone, or for drawing metal between two shoulders or projections. ”

“ He was dressed in trico-tights, with a cloak of skins, wore a wig and an artificial beard, and with white, weak, genteel hands (his easy movements, and especially the shape of his stomach and his lack of muscle revealed the actor) beat an impossible sword with an unnatural hammer in a way in which no one ever uses a hammer; and at the same time, opening his mouth in a strange way, he sang something incomprehensible. The music of various instruments accompanied the strange sounds which he emitted. ”

“ The head of the hammer, which of course works vertically, is detachable, so that if the monster breaks his steel fist upon coil or anvil, another can be quickly supplied. These huge heads alone are as big as a sugar-hogshead, and come down upon the hot iron with an energy of more than a thousand foot-tons. ”
