IMPERIAL

PATENT OFFICE.

According to the present invention, by modifying what is known in mechanics Peaucellier's degree guidance created a mechanism in which in more advantageous and movement can be initiated more cheaply.

The invention relates to the transmission of movement in a straight direction, as with balance beams, pumps, cranes, looms, devices for moving the Piano keys, pedal levers and the like, in which the force is transmitted in a straight direction is desirable or necessary.

Fig. Ι shows the application of the degree guide on a balance or other vibrating beam, FIG. 2 shows a basic profile of the degree guide and FIG. 3 shows a basic profile of a Modification according to Fig. 2.

A lever with two arms of equal length is rotatably mounted at F on a fixed part of the balance; these arms end at E ¹ respectively. E ² . L ¹ and L ² are the pins seated at the ends of the stationary part on which the steering rods of the arrangement described below are pushed.

At E ¹ sit rotatably the two joints E ¹ A and CE ¹ , respectively at A. C are in a rotatable connection with the joints AB and BC; the latter are rotatably connected under each other at B and are of the same length as the joints E ¹ A and CE ¹ , so that a rhombus is formed. At L ¹ , a steering rod AL ^{1 is} rotatably mounted on the stationary part, the other end of which is connected to the joints AB and E ¹ A in a rotatable manner through the pin A. In the same way, a 'handlebar CL ¹ of the same length as AL ^{1 is rotatably mounted at L 1} , the other end of which is rotatably connected to the joints BC and CE ^{1 at C.} This joint arrangement forms one half of the rocker arm; is point B shifted, does it describe _? as indicated by dots in Fig. 1, a straight line.

The other arm of the rocker arm is rotatably connected at E ² to the joints HE ² and E ² D , which in turn are rotatably connected to the joints G H and DG of the same length at H and D. The latter are rotatably connected to each other at G.

The handlebar HL ² is rotatably mounted at H in a rotatable connection with the joints HE ² and GH and also rotatably mounted at L ² on the fixed part, while the handlebar D L ^{2 of} the same length is mounted on the fixed part at L ^{2 and} on the joints E ^{2 at D} D and DG is rotatably connected. Both groups of joints are rotatable at L ¹ and also at L ² on the fixed part, but are also rotatably connected to a lever swinging at F; If one group of the joints swings out, the other group moves in the opposite direction, but point G shifts parallel to the direction of movement of B.

In the modification of Fig. 3, the arms of the lever swinging around F lie in a straight line, while the fixed part is designed in such a way that it follows this degree

The extension of the lever. In some cases there is only one set of joints for use, for example, when it appears desirable, the moving device to move in a straight line, but it does not matter whether the drive lever in the Circles around or not. This arrangement is shown, for example, in FIG which the four-sided joint (rhombus) is only attached to one arm.

In the arrangement according to Fig. 4 (view) and Fig. 5 (Grundrifs), the arms of the Rocker arm of various lengths, and one arm is only half as long as the other. Otherwise, this modification agrees with the arrangement according to FIG. 1 but the joints belonging to the short arm are correspondingly smaller.

In the arrangement according to FIGS. 6 and 7 (view and outline), which illustrates the operating arrangement for a hand pump, the handle is moved back and forth in a straight line and consequently the pump piston rod is also moved in a straight line. Here the arms of the lever are next to each other, as are the sides of the DEHG rhombus. The joints are of different lengths and form a lever with unequal arms, the arms of which can, if necessary, be united without deviating from the essence of the invention.

Fig. 8 shows a side view of a handlebar in which a perpendicular movement is converted into a horizontal movement. This type of movement is achieved by means of an angle lever rotatably mounted at F , the legs of which are at right angles to each other.

In the handlebar according to Fig. 9, the arrangement of the joints is the same, only here the legs of the angle lever are not at right angles, but at an obtuse angle to each other.

In the middle of the link shown in side view in FIG. 10, two horizontal movements in opposite directions are brought about by a single vertical movement. For this purpose, the handlebar according to FIG. 1 is combined with that according to FIG. When point B goes down in the direction of the arrow, point G is moved in the direction of the arrow, whereas point N is moved in the other direction of the arrow, i.e. opposite to G. This handlebar is particularly suitable for the key mechanisms of pianinos, in which a reverse movement and two parallel movements are necessary.

Claims (4)

Patent Claims: 1. A type of P eaucellier's degree guide put together double degree guide, characterized by the arrangement of two four-sided hinges, each of which is connected to the end of a two-armed lever (E ¹ FE ² J swinging around a fixed pivot point (F) , while the upper and lower pivot points of said four-sided articulation are rotatably connected by steering rods of equal length (AL ¹ and CL ¹ or DL ² and HU) with the fixed pivot pins (L ^{1 and} L ² J , which are located behind the pivot point (F) on the associated hinge on the opposite side are located on four sides (FIGS. 1 to 5). 2. The modification of the double degree guide according to claim 1. in such a way that the four-sided hinge are one behind the other and the same-armed. respectively unequal arm levers (E ¹ FE ' ² ) according to FIGS. 1 to 3 respectively. Fig. 4 and 5 is converted into a one-armed lever (E ² F) (Fig. 6 and 7). 3. The modification of the double degree guide according to claim 1. in such a way that the four-sided hinge to the. Ends of a rotatably mounted angle lever (E ¹ FE ² ) are connected and the pivot points (A and C or D and H) of the four-sided mentioned by steering rods of equal length (AL ¹ and CL ¹ or DL ² and HL ² ) with the fixed pivot pins (L ¹ and L ² ) are in connection (Fig. 8 and 9). 4. The modification of the double degree guidance according to claim 1 in such a way, that the same is combined with that according to claim 2, in which combination the rectilinear movement introduced into the mechanism in two opposite directions Movements directed towards one another and at right angles to the initiated movement are implemented (Fig. 10).
