Description

Rolling weight for running weight scales, which can be adjusted by means of a 1V (driver is moved on the balance beam. The invention relates to a rolling weight which is moved around its own circumference on the balance beam by a driver, which does not touch the rolling weight in the equilibrium position and that under the influence the individual weight positions automatically due to its eccentric center of gravity on the balance beam.

In similar known designs, a barrel weight is on a notched bar of the barrel weight, with the barrel weight in front Reaching the notch is released by the driver and then automatically moved to the notch setting. The barrel weight then settles with his Cylinder jacket on the notch legs and automatically determines its position, or it carries a tooth that is pressed into the notch, making it the correct one Setting position.

In the present invention, in the embodiment according to Fig. I to 16 of the principle of the notch setting, which is used for the previously known designs is fundamental, distanced.

The partial shift and thus the adjustment of the rolling weight takes place in its individual positions corresponding to the various load weights in the embodiment according to Fig. i to 6 in that the rolling weight, which in these Positions always with the same generating line of his cylinder jacket on the balance beam rests (which is due to an eccentric arrangement of the center of gravity of the rolling weight with respect to its cylinder axis is reached), has a cylinder circumference which is as large as the distance to be covered. Will now be a sliding shift the weight is prevented, the exact adherence to the required route size is required when rolling the weight from a stable equilibrium position of its center of gravity in the next guaranteed.

The rolling weight can have an unchangeable and a changeable center of gravity to have.

Fig. I to d. show schematically an exemplary embodiment of a Rolling weight with a rigid center of gravity. The role R, the cylinder circumference of which is the same is the desired distance between the individual weight positions, has both sides a cylindrical neck H to which an additional weight G is firmly attached, whereby the center of gravity is shifted to S out of the cylinder axis.

The rolling weight rests freely rollable on the balance beam (running weight beam) W, is due to the corrugation or toothing A of the balance beam, in which the ring gear B of the rolling weight engages (see Fig. 3), prevented from sliding forward, while the compulsory rail Z prevents A and B from disengaging or each other jam, but does not affect the role in any way in the normal position. the end In its basic position (Fig. i left) the rolling weight is pressed by the driver M, which is out of contact with the balance beam and engages the neck H of the roller, whereby the center of gravity S is lifted into the unstable equilibrium by the height hl (Fig. 2 left) and then, following the law of gravity, after this position has been exceeded without being influenced by the driver in the stable Adjusts the equilibrium position in which the rolling weight, unaffected by the The carrier remains (see Fig. 2 on the right), whereupon in the horizontal insertion position of the balance beam the brands of the additional weight G with the route brand 2 of the balance beam W must match. Fig. 3 shows the rolling weight in plan view, Fig.q. in side view. In the case of heavy rolling weights, the one to be performed on the carrier would be Work as a result of the necessary lifting of the center of gravity S by the height hl be too large. Figs. 5 and 6 show an example arrangement of a rolling weight with variable Center of gravity. Instead of the rigid additional weight G, there are drum-like ones here closed container T attached to the roller, which is filled with liquid F, e.g. B. with mercury. This is where the center of gravity becomes when rolling the weight only raised by a small amount h2, which makes the work of moving it much easier will. When the rolling weight has exceeded the position (Fig. 6 right), will move the fluid to the lowest position and the rolling weight the same Position as before, but shifted parallel to take up one circumference of the coat. Fig. 5 shows this embodiment in side view.

In the embodiment according to Fig. 7 to i i, the individual from Rolling weights achieved weighing positions to be taken by the fact that the rolling weight automatically under the influence of its own gravity on the balance beam in equally spaced cutting edges - z. B. in the manner of a pendulum - hangs, the stable balance of the rolling weight is achieved in that its The center of gravity always comes to lie below the hanging edge. The hanging edges can either be at intervals of an entire circumference of the roll weight Rolling weights with a variable center of gravity but also attached at intervals which correspond to a fraction of the circumference of the jacket.

In the latter case, rolling weights filled with liquid (Fig. 7 to i i) the drum container, with rolling weights with a movable fixed additional body (Fig. 12 to 16) the positive guidance must be shaped accordingly.

In Fig. 7 to ii the arrangement is similar to Fig. I to 6, only the cylinder circumference and the ring gear B of the rolling weight is interrupted once or several times by the recess for the suspension sockets P f and the suspension cutting edges Sch are at corresponding intervals in the teeth El of the balance beam inserted. Fig. 7 shows the rolling weight R, which, under the influence of its weight, gradually leans against the cutting edge Sch and then tilts with its pan Pf over the cutting edge Fig. 8. Fig.g shows how the rolling weight is brought out of its stable equilibrium position by the driver, while Fig. Figs. 12 to 16 show an embodiment in which the variability of the rolling weight center of gravity is brought about by an additional weight Z that can be moved in the rolling weight, but the positions of the center of gravity of the rolling weight in certain rolling positions are not the natural ones, but rather by a structural part of the balance that is outside the rolling weight to be influenced. The appropriate shifting of the center of gravity results in an easier and smoother movement of the rolling weight and protects the main cutting edges of the balance beam.

In the exemplary embodiment according to Figs. 12 to 16, this is Additional weight Z horseshoe-shaped. It spans the weight bar without closing it touch, and at both ends has rollers r, which are located in the raceways Move L of the roller. The career paths are here z. B. as spherical squares educated.

The roles r always strive in the corners of the raceways when the square sides the same have achieved the necessary inclination.

The middle piece J of the additional weight Z is between the arms A of the Driver M located.

The additional weight is therefore due even before it is on the running track the inclination of the same would be set in motion, pulled forward by the arms of the carrier, sets its movement automatically when the required minimum incline of the track is reached continues and is in the last part of the same by the arms of the driver on the middle piece J held back and gradually released by the center piece J on the Arms of the driver slides down until the rolling weight is stable has reached. This is followed by neither the center piece J nor the rolling body that has hitherto been used was based on the driver, this was in its movement and therefore step with this out of touch.

The additional weight changes its position as a result of this arrangement low kinetic energy and glides gently into the corners of the raceways.

Further, the necessary work that is required becomes the extra weight to lift until the raceways have the necessary tendency to self-actuate Unrolling the additional weight have achieved due to the premature Prefer the additional weight greatly reduced.

Finally the arms of the carrier prevent the additional weight from swinging and thus also the pendulum movement of the entire rolling weight.

Figs. 17 to 20 show the embodiment of such a rolling weight with notch setting.

The concept of the invention is based on similarly known barrel weights, that they are released by the driver before reaching a notch, whereupon move the barrel weights automatically into the notch. The present rolling weight loosens itself automatically after reaching the notch from the driver to its further Movement no longer to follow.

In the version according to Fig. 17 to 2o, the rolling weight carries on his Circumference of cutting edges S with which it engages in the notches of the balance beam. the Construction and mode of operation is similar to that in Fig. 3. Here, too, the additional weight Z is initially inevitably brought forward and moves after the required level has been achieved The incline of the career paths continues automatically before reaching the corner of the career path held back by the driver arms on the middle piece J, which according to the As the driver advances, it slides down until the rolling weight is down under the effect of its eccentric center of gravity with the cutting edge in the notch and has come into stable equilibrium.

This is followed by neither the middle piece I nor the roller body with its Necks H, which were previously based on the driver, its movement and come out of touch with him.
