Flatrod system

The Art linkage, also bar work, bar or rod line art is an invention from the mining industry, which served mechanical movement, which is generated by a Kunstrad to transfer over small distances. The replica of an art boom can be seen for example in Bad Kösen an der Saale, a reconstructed Kunstrad, which served to drive the linkage is in Clausthal- Zellerfeld in the Upper Harz.

Basics

The Art linkage comes from the time before the invention of the steam engine and electricity. With the art boom it was possible to actuate driving skills and pumps arts, although the available water wheel ( Kunstrad ) uses no hunting, but a rotary motion. In order for the art linkage could be put in a pendulum motion, had to be produced by specially shaped linkage parts movement direction reversal. The parts of the plastic linkage that were mounted in the shaft called shaft linkage or lift linkage. In sections mounted rod art were referred to as linkage distance.

For the power transmission over wide distances between the prime mover and lift linkage, the linkage field served. At the wheel shafts, the Ansetzröhren and Ansteckkielen, but also attached to other portions of the wood art rod rings made ​​of iron is called art rings. As an art bars is called the long rectangular blocks of wood, which served to bring the work of art in motion. The assemblages of the art rods are called art locks or bar locks. They are constructed by teeth so that the rods can be tenoned each other and be fixed by means of bolts or screws.

The lift linkage

A lifting bar extending vertically in the art shaft to transmit the force to the individual pump units. It consists of about 19 to 20 centimeters thick square spruce timbers. The timbers are interlocked laterally at the ends and are connected with correspondingly toothed wooden hangers. The wooden plates are pressed with art rings fixed to the Hubstangenenden. In addition, the Art rings are secured with set-through pin against displacement. At certain intervals, there are side-mounted hook arms that are used to mount the piston rods. So that the horizontal movement of the rod box, a vertical movement is a lifting bar is attached to a synthetic cross. The connection to the Art Cross via an art castle. For uniform load usually two lifting links are used, thus takes place in a mutual load balancing.

The field linkage

The pitch linkage was used to direct the power of the prime mover over longer distances to the art sets the shaft linkage. This was necessary if the engine could not be positioned on or immediately adjacent the slot. A box boom has the disadvantage that there will be additional losses due to the large mass to be moved. By the intermediate field linkage occurs due to the reciprocating motion of the linkages in the (locks ) to a stroke loss of 25 to 50 percent. Furthermore, additional timber required for the construction of a linkage field. This is very maintenance-intensive due to the weather, so it required additional staff to check the box, linkage and maintain.

The field linkage consisted of several wooden art bars that were provided with iron fittings. So-called art locks were at the ends of the side art bars. These were so cut and fitted so that a rod could be mortised into the other rod. This was necessary so that art bars in the down -and-forth pushing, or the up and down - move could not slide apart.

There were two types of field linkages: Field linkage with rollers and field linkage with swinging. In the field linkage with rolling the rod is moved on rollers. The rolls consist of eight to ten inches thick logs that are to the lower side firmly inserted into the ground and fixed with braces. To reduce friction, the linkage is provided in the area of the individual rolls over a complete stroke length with a tow bar made ​​of beech wood.

The field linkage with swing consists of a large swing, the so-called Wagbaum, of several small swings, the field poles, and the so-called Löcken with rhinestones trees. In the center of the main wing is a transitory pin on which it moves in Pfoteisen. At the two ends of the main rocker arm several holes are placed, in which is fixed with iron rings Augeisen inserted. In each Augeisen up to three eyes, on the one hand the rod basket and the other side of the field pole can be mounted. To make the stroke variable, more eyes will be mounted separately. To make the stroke longer or shorter, the cage rod is suspended accordingly. The rocker arms of the smaller wings are used to adapt the pitch linkage accordingly. This adjustment is necessary because the field linkage would otherwise break easily due to its length. The so-called Löcke are increased documents for the swing. They are placed every 2 to 3 fathoms, and have at the upper end bent stems - the so-called cuttings. The Löcke be provided with struts and base pads so that the linkage is adjusted in height so that the field poles can move in a straight line. All pins on the wings are adjusted so that they are far from equal to two.

Movement direction reversal

When the reverse movement of the rotary movement in the horizontal or vertical movement, but also by the horizontal movement to the vertical movement, use was made of specially shaped rod elements: the one of the curved pin and on the other hand the cross art.

The curved pin is bent at a right angle a rod member which serves as a continuation of the shaft journal. Its mission is to transform the rotary motion of the water wheel in a horizontal or vertical movement. There was the so-called basket or Bläuelstange On the crooked pin. With the curved pin, the rotational movement of the plastics wheel in the field poles, or the shaft rod has been transmitted, then performing the spherical motion. The operation of the curved pin is very similar to the function of a compare current crankshaft and Bläuelstange with the function of a connecting rod.

The Art Cross, whole or broken clamp, Kunstwinkel or just called Cross, consists of a strong wooden bell crank. The Art Cross was either connected directly to the basket rod of Krumm pin or via a field linkage with it. There were three different types of artificial crosses. Depending on the design they were referred to as whole art crosses, half or quarter art crosses crosses. The whole art cross is a cross with four arms. Of these arms each of two opposing arms are connected to the shaft rod and the other two arms of the linkage field. Half the cross is a cross with three arms. Two arms lie horizontally, and the third is upright. At the two horizontal arms of the shaft linkage and the third arm the cage rod is connected. In a quarter cross- arm, the linkage and an arm is connected to the Bläuelstange.

The use of artificial crosses was indispensable to the force deflection for various reasons. Even if the art wheel was mounted directly above the Kunstschacht, due to the direct linkage attaching the shaft to the curved pin has a very high load on the so-called crank warts. The friction in the direct mounting was substantially greater. In addition, the shaft rods never produced a very "clean" vertical movement but oscillated laterally back and forth slightly.
