Shuttle embroidering machine
First Claim
1. Shuttle embroidering machine comprising a plurality of elongated horizontally arranged needle carriers and of elongated horizontally arranged drill carriers arranged to be displaced approximately at right angles relative to the plane of an embroidery frame, each said needle carrier and drill carrier having a first end and a second end, a needle inserted into the first end of each said needle carrier, a drill inserted into the first end of each said drill carrier, a generally horizontally extending first arm attached to the second end of each said needle carrier, a generally horizontally extending second arm attached to the second end of each said drill carrier, each of said first and second arms being pivotally displaceable about a horizontal axis, each of said first and second arms having a first end and a second end with said first ends of said first and second arms being connected to the second ends of the respective said needle carriers and drill carriers, a drive element for the operative displacement of said needle carriers and drill carriers, said first and second arms being shaped for selective and form-locking engagement with said drive element, wherein the improvement comprises that the second ends of said first and second arms being displaceable along a vertical path when said first and second arms are pivotally displaced, individually controllable locking members located in the vertical path of displacement of the second ends of said first and second arms for selective locking engagement with said first and second arms, first control members engageable with said first arms and second control members engageable with said second arms for selectively pivoting said first and second arms into and out of locking engagement with said locking arms.

Abstract
In a shuttle embroidering machine a plurality of needle carriers and drill carriers are arranged to be displaced at approximately right angles relative to the plane of an embroidery frame. Each needle carrier has a needle inserted into one end and each drill carrier has a drill inserted into one end. A generally horizontally extending arm is attached to the opposite end of each needle carrier and drill carrier. The arms are pivotally displaceable about a horizontal axis. One end of each arm is connected to a needle carrier or a drill carrier and the other end is displaceable along a path due to the pivotal displaceability of the arms about horizontal axes. A drive element provides the operative displacement of the needle carriers and drill carriers. The arms are shaped for selective form-locking engagement with the drive element. Individually controllable locking members are located in the path of displacement of the ends of the arms spaced from the needle carriers and drill carriers so that the needle carriers and drill carriers can be held in an inoperative position. Control members are engageable with the arms for selectively pivoting the arms into or out of locking engagement with the locking arms.
