Abstract
Abstract At an embroidery machine there are mounted and displaceably guided two rows of embroidering implement rods which can be connected so as to be operatively coupled or decoupled in accordance with a desired program to a related one of two operatively associated oscillating drive rails. The embroidering implement rods which are related to the same embroidery location or position and which are, for instance, arranged in superimposed relation, can be simultaneously coupled to or decoupled from the operatively associated drive rail by means of a common switching lever. This switching lever can be actuated either directly or manually by means of adjustment levers and automatically by means of an electromagnetic device. This individual switching of all implements of an embroidery location enables easily adjusting any desired combination of working and inactive embroidery locations.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
149 words
An embroidery machine comprising: embroidering implement rods mounted in at least two rows and displaceably guided at the embroidery machine; a respective oscillatingly driven drive rail operatively associated with at least predetermined ones of the embroidering implement rods of a given row; each of said embroidering implement rods being operatively connectable with its operatively associated oscillatingly driven drive rail in that each said embroidering implement rod can be selectively coupled or decoupled from its related drive rail; means for operatively connecting each of said embroidering implement rods to its related oscillating drive rail; said operatively connecting means comprising a common switching lever for simultaneously coupling to or decoupling from the related operatively associated drive rail two of said embroidering implement rods which are related to the same embroidery location; said common switching lever being manually actuatable; and means including an electromagnetic device for automatically actuating said common switching lever.
Claim 2
Dependent Claim
149 words
An embroidery machine comprising: embroidering implement rods mounted in at least two rows and displaceably guided at the embroidery machine; a respective oscillatingly driven drive rail operatively associated with at least predetermined ones of the embroidering implement rods of a given row; each of said embroidering implement rods being operatively connectable with its operatively associated oscillatingly driven drive rail in that each said embroidering implement rod can be selectively coupled or decoupled from its related drive rail; means for operatively connecting each of said embroidering implement rods to its related oscillating drive rail; said operatively connecting means comprising a common switching lever for simultaneously coupling to or decoupling from the related operatively associated drive rail two of said embroidering implement rods which are related to the same embroidery location; said common switching lever being manually actuatable; and means including an electromagnetic device for automatically actuating said common switching lever.
Claim 3
Dependent Claim
25 words
The embroidery machine as defined in claim 1, wherein: said common switching lever can be manually actuated directly by acting upon said common switching lever.
Claim 4
Dependent Claim
24 words
The embroidery machine as defined in claim 1, wherein: said common switching lever can be actuated manually by means of a manual positioning lever.
Claim 5
Dependent Claim
47 words
The embroidery machine as defined in claim 1, wherein: said electromagnetic device is not actuated when said common switching lever is located in a manually initiated arrested end position; and said arrested end position causing said embroidering implement rods to be decoupled from the related drive rails.
Claim 6
Dependent Claim
41 words
The embroidery machines as defined in claim 1, wherein: said electromagnetic device comprises part of a positioning device for a related one of said switching levers; and said positioning device further comprising a mechanical device operatively associated with said electromagnetic device.
Claim 7
Dependent Claim
60 words
The embroidery machine as defined in claim 5, further including: a pawl lever cooperating with said common switching lever; said pawl lever being displaceable between a first end position and an intermediate position by means of said electromagnetic device; and said pawl lever being displaceable between said intermediate position and a second end position by means of said mechanical device.
Claim 8
Dependent Claim
34 words
The embroidery machine as defined in claim 6, wherein: said common switching lever having upper and lower positioning arms; and said pawl lever acting upon the lower positioning arm of said common switching lever.
Claim 9
Dependent Claim
38 words
The embroidery machine as defined in claim 7, further including: a permanent magnet arranged at a free end of said pawl lever; and said permanent magnet constantly adhering to an iron core of said electromagnetic device when deenergized.
Claim 10
Dependent Claim
38 words
The embroidery machine as defined in claim 6, wherein: said mechanical device comprising an externally actuatable tilt lever; and said pawl lever being displaceable from said intermediate position into said second end position by pivoting said tilt lever.
Claim 11
Dependent Claim
64 words
The embroidery machine as defined in claim 1, wherein: said operatively connecting means comprising a respective latching element hinged to each of said embroidering implement rods; a downwardly open coupling groove provided at the free end of each said latching element; and a respective coupling nose provided at each of said drive rails for latching with said coupling groove of the related latching element.
Claim 12
Dependent Claim
57 words
The embroidery machine as defined in claim 10, further including: inclined control surfaces provided at said latching elements; said common switching lever having a transverse web; and control surfaces provided at said transverse web of said common switching lever cooperating with said inclined control surfaces for decoupling said two embroidery implement rods from their related drive rails.
Claim 13
Dependent Claim
29 words
The embroidery machine as defined in claim 10, wherein: said coupling grooves provided at said latching elements being located essentially in the lengthwise axis of said embroidering implement rods.
Claim 14
Dependent Claim
50 words
The embroidery machine as defined in claim 10, wherein: said coupling grooves and said coupling noses being structured such that they fit into each other in a wedge-shaped fashion; and said coupling grooves and said coupling noses having a wedge angle which is approximately equal to a friction angle thereof.
Claim 15
Dependent Claim
50 words
The embroidery machine as defined in claim 1, wherein: said common switching lever comprising a first manual positoning arm extending upwardly past an upper row of said implement rods; and said common switching lever further comprising a second positioning arm extending downwardly past a lower row of said implement rods.
Claim 16
Dependent Claim
42 words
The embroidery machine as defined in claim 1, further including: manual positioning lever means for releasably arresting said common switching lever in an end position; and said end position causing said embroidering implement rods to be decoupled from their related drive rail.
Claim 17
Dependent Claim
51 words
The embroidery machine as defined in claim 1, wherein: a number of said embroidery locations are combined into a respective block unit and arranged in a bearing housing; a support rail provided for the embroidery machine; and said bearing housings being exchangeably mounted upon said support rail of said embroidery machine.
