Abstract
Abstract An arrangement for reading out through electrically coded signals, counter registrations and indications. A common shaft within a supporting frame of a unit holds a plurality of electrical contact discs which are rotatably mounted on the shaft. The counter to be read out electrically is provided with individual rotatable drums connected to the electrical contact discs so that these are rotated in correspondence with the drums when the frame is detachably mounted on the supporting means of the counter. Through the application of contact blades supported on a contact carrier block within the frame member, the counter indications are read out through digitally coded electrical signals. The counter can be used in conjunction with a printout mechanism through which printout is realized in a uniquely defined numerical order.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
153 words
Electrical readout for counters, comprising supporting means; counter means mounted on said supporting means and including a series of individually rotatable counter drums having counter gear teeth; means for rotating said counter drums to a position representing a value; and a readout unit including a frame, and means detachably mounting said frame on said supporting means, a series of individually rotatable contact discs mounted on said frame and having connecting gear teeth meshing with said counter gear teeth of said counter drums, respectively, each contact disc including at least one contact layer having circumferentially extending contact portions representing different values, and a series of sensing contact means mounted on said frame for sensing said contact layers of said contact discs, respectively, each sensing contact means including sensing contacts engaging correlated contact portions of the respective contact layer for electrically transmitting information represented by the angular positions of said counter drums and contact discs.
Claim 2
Dependent Claim
153 words
Electrical readout for counters, comprising supporting means; counter means mounted on said supporting means and including a series of individually rotatable counter drums having counter gear teeth; means for rotating said counter drums to a position representing a value; and a readout unit including a frame, and means detachably mounting said frame on said supporting means, a series of individually rotatable contact discs mounted on said frame and having connecting gear teeth meshing with said counter gear teeth of said counter drums, respectively, each contact disc including at least one contact layer having circumferentially extending contact portions representing different values, and a series of sensing contact means mounted on said frame for sensing said contact layers of said contact discs, respectively, each sensing contact means including sensing contacts engaging correlated contact portions of the respective contact layer for electrically transmitting information represented by the angular positions of said counter drums and contact discs.
Claim 3
Dependent Claim
36 words
Electrical readout as claimed in claim 1 wherein said counter gear teeth radially project from the peripheries of said counter drums; and wherein said connecting gear teeth radially project from the peripheries of said contact discs.
Claim 4
Dependent Claim
36 words
Electrical readout as claimed in claim 1 wherein each counter gear tooth and each connecting gear tooth corresponds to a digit, and wherein adjacent connecting gear teeth define recesses shaped corresponding to said counter gear teeth.
Claim 5
Dependent Claim
23 words
Electrical readout as claimed in claim 1 wherein said contact portions include codified contact tracks so that information is transmitted in coded form.
Claim 6
Dependent Claim
42 words
Electrical readout as claimed in claim 1 wherein each contact disc is made of insulating material, and wherein contact layers are located on both sides of each contact disc and engaged by the sensing contact means correlated with the respective contact disC.
Claim 7
Dependent Claim
34 words
Electrical readout as claimed in claim 5 wherein each contact disc includes a bearing bushing passing through said insulating material and conductively connecting said contact layers on opposite sides of the respective contact disc.
Claim 8
Dependent Claim
45 words
Electrical readout as claimed in claim 5 wherein said two contact layers of each contact disc have contact portions including contact tracks codified in accordance with different codes so that the same information represented by said counter drums can be transmitted in two different codes.
Claim 9
Dependent Claim
20 words
Electrical readout as claimed in claim 5 wherein at least one of said contact layers has a zero position indication.
Claim 10
Dependent Claim
54 words
Electrical readout as claimed in claim 5 wherein said sensing contact means include insulated carriers on said frame, and pairs of contact blades mounted on said carriers, respectively, and wherein the blades of each carrier resiliently abut opposite sides of the same contact disc for sensing said contact portions of said two contact layers.
Claim 11
Dependent Claim
29 words
Electrical readout as claimed in claim 9 wherein said contact blades of each pair have contact points abutting axially aligned points on opposite sides of the respective contact disc.
Claim 12
Dependent Claim
22 words
Electrical readout as claimed in claim 9 wherein said carriers are mounted adjacent each other on said frame and form a block.
Claim 13
Dependent Claim
38 words
Electrical readout as claimed in claim 1 comprising another unit exchangeable for said unit and having a correspondingly shaped frame fitting on said support, and a different number of correlated counter drums, contact discs, and sensing contact means.
Claim 14
Dependent Claim
28 words
Electrical readout as claimed in claim 1 wherein said unit comprises arresting means for arresting said counter drums and contact discs in uniquely defined angular positions representing digits.
Claim 15
Dependent Claim
37 words
Electrical readout as claimed in claim 1 wherein said means for rotating include measuring means connected to said counter means so that said counter means and said contact discs represent the quantity measured by said measuring means.
Claim 16
Dependent Claim
24 words
Electrical readout as claimed in claim 1 wherein said counter drums have digital printing portions separated by recesses engaged by said connecting gear teeth.
