Pointer carriages have become known

which the weighing load is transferred to two springs of different strength by means of an intermediate lever is transmitted. This balance is used for fine or rough weighing. The two springs kick always, albeit in varying degrees in effect. The two pointers must each point on a special scale.

With the balance according to the present invention,

ίο. in which also the weighing load by means of intermediate levers is transmitted, inclination or spring trolleys are used, which are graduated by Weights are balanced in such a way that only one or more consecutively (not but all at the same time) come into effect.

The purpose of this invention is to split the weighing load into several parts in order to achieve the The deflection must be kept within certain limits, since only a limited one with the cutting edge arrangement Deflection angle is possible. All pointers can be on a common scale for Rash come.

Fig. 1 is a longitudinal section, Fig. 2 is a cross section the balance; Fig. 3 shows the pointer setting for a in the following description given example; Figures 4 and 5 are two related projections for one different kind of pointer arrangement; Fig. 6 shows the pointer setting of the example mentioned in the manner of the embodiment shown in FIGS. 4 and 5 ″.

h is the transfer lever of a balance. This transfers by means of the hanger ¹ a load effect on the intermediate lever ¹ h. The intermediate lever h ¹ transfers the load effect to the J by means of the hangers a ² and a ^3. The pointers z ¹ , z ² , z ³ and z ⁱ play on one

45

Intermediate levers h ² and h ³ , which again by means of the hangers « ⁴ , α ⁵ , α ⁶ and α ^{7 transfer} the load effect to the inclination carriages n ¹ , n ² , n ^s and w ⁴ , in equal parts, since the middle cutting edge of each intermediate lever is equidistant from its end cutting edges.

The inclination carriages n ¹ , n ² , n ^s and n * have the pointers z ¹ , z ^% , z ^s and z ⁴ · and the weights g ¹ , g ² , g ³ and g ⁴ , which are of different sizes and the load counteract the Wagbrücke.

Since the weights g \ g ² , g ^s and g ^{4 are} unequal, with a certain load on the wagon bridge the inclination scale with the smallest weight g ^{1 is first} , with increasing load the inclination scale with the next higher weight g ² , etc. come into action.

Scale s and carry near their upper end the tablets t ¹ , t ² , i ³ and i ⁴ (Fig. 2 and 3), on which is the number that must be added to the weight display of the pointer on the scale to get the weighing result admit. The following example should make the effect of the balance clearer:

'Assume that the scales are set up to determine loads up to 40 kg. The scale goes up to 10 kg. On the wagon bridge there would be 16.5 kg. This load causes a pull in the hanger a ¹ = p ¹ . This train is broken down into the two components /) ² and f ³ occurring in the hangers a ² and a ^s , which finally split into those in the hangers α ⁴ , α ⁵ , α ⁶ and α ¹

Components φ ⁴ ; Decompose φ ⁵ , -φ ^β and φ ¹ . The middle cutting edge of each intermediate lever is equidistant from its end cutting edges; it is therefore φ ² = φ ³ and φ * = φ ⁵ = φ ⁶ = f.

The weight g ¹ is chosen so that with a load of 10 kg on the carriage bridge, the corresponding pull p ° ^{occurring in the hanger «4} is able to make the pointer z ^{1 of} the inclination carriage n ¹ deflect across the entire scale. Since the pull φ * caused by the load of 16.5 kg is greater than φ °, the pointer z ¹ will deflect beyond the scale up to a stop that limits the movement of the pointer. The weight g ² is chosen to be so large that the pull φ ° occurring under a load of 10 kg in the hanger a ⁵ sets the pointer z ² to the zero point of the scale.

Since the pull -φ ⁵ caused by the load of 16.5 kg is greater than φ °, the inclination carriage n ^{2 will} make the movement corresponding to this difference and the pointer z ^{2 will} be positioned between the sixth and seventh division, as shown in FIG 3 shows.

The pointer z ² carries the tablet t ² with it

the number 10; it stands between the sixth and seventh division; the weighing result is therefore 10 + 6.5 = 16.5 kg.

To avoid adding and to be able to read the weighing result immediately, two or more scales are arranged one below the other, and the lower ones form the Continuation of the top. The hands do not have tablets with numbers, but are as can be seen from Fig. 4 and 5, made unequal length and each play on one different scale. Fig. 6 shows such a pointer arrangement on the previous example applied.

The distances of the middle cutting edge an intermediate lever of its end cutting edges can also be made unequal in size. Likewise, the scales can also be of different sizes in the arrangement with one another. It can e.g. B. the first from 1 to 10 kg, the second from 10 to 30 kg, the third from 30 kg up to 60 kg and the fourth from 60 to 109 kg be shared etc.

Claims (1)

Patent claim: Pointer dare with one or more intermediate levers transferring the weighing load, characterized in that the inclination associated with the intermediate lever or levers or spring trolleys are balanced by means of graduated weights in such a way that one or more, depending on the load Chariots come into effect one after the other, with either each pointer on a particular one Scale or all pointers come to a deflection on a common scale. 1 sheet of drawings.
