Abstract
Embodiments of a quill stop are disclosed. The quill stop can move between an open and closed position. The quill stop has a left and a right securing member, a locking element, a right arm, a left arm, and a left arm spring. The right arm can actuate the locking element out of engagement with a locking projection so that the right securing member and the left securing member can move relative to each other and allow a rod to be inserted between them. The locking element prevents unwanted actuation of the quill stop during operation.
Claims8
An apparatus comprising:
- a threaded rod, wherein the threaded rod comprises a threaded rod pitch;
- a quill stop, attached to the threaded rod and capable of moving between an open position and a closed position, comprising:
- a left securing member comprising a locking element pivot;
- a right securing member comprises a locking projection;
- an engagement portion defined by the left securing member and the right securing member, wherein the engagement portion defines a thread the thread has a pitch that corresponds to the threaded rod pitch;
- a locking element that defines a locking projection receiving space and comprises a locking element abutment, wherein the locking element is configured to rotate about the locking element pivot;
- a right arm comprising a right arm actuator;
- a left arm defining a left arm spring space;
- a left arm spring located at least partially inside the left arm spring space, wherein the left arm spring biases the locking element away from the left arm and the locking element into abutment of the locking projection;
- a securing spring coupled to the left securing member and the right securing member, wherein the securing spring biases the left securing member and the right securing member together;
- wherein when the quill stop is in the closed position and attached to the threaded rod, the engagement portion defines an engagement space and the engagement space is fully enclosed;
- the engagement portion thread engages the treaded rod the right arm actuator abuts the locking element abutment, and the locking projection is located inside the locking projection receiving space;
- when the quill stop is in the open position the locking element abutment abuts the locking projection, the left arm spring is compressed, and the securing spring is expanded.

An apparatus comprising:
- a quill stop, capable of moving between an open position and a closed position, comprising:
- a left securing member comprising a locking element pivot;
- a right securing member comprises a locking projection and a right arm securing element;
- an engagement portion defined by the left securing member and the right securing member, wherein the engagement portion is threaded;
- a locking element that defines a locking projection receiving space and comprises a locking element abutment, wherein the locking element is configured to rotate about the locking element pivot;
- a right arm comprising a right arm actuator;
- a left arm defining a left arm spring space;
- a left arm spring located at least partially inside the left arm spring space, wherein the left arm spring biases the locking element away from the left arm and the locking element into abutment of the locking projection;
- a securing spring coupled to the left securing member and the right securing member, wherein the securing spring biases the left securing member and the right securing member together;
- a right arm abutment;
- and
- a left stop
- wherein when the quill stop is in the closed position, the engagement portion defines an engagement space and the engagement space is fully enclosed;
- the right arm actuator abuts the locking element abutment, and the locking projection is located inside the locking projection receiving space;
- when the quill stop is in the open position the locking element abutment abuts the locking projection, the left arm spring is compressed, and the securing spring is expanded;
- and when the quill stop is in the open position, and a compression force that maintains the quill stop in the open position is removed from the left arm and the right arm:
- the securing spring biases the left securing member and the right securing member together,
- the locking element abutment will slide along the locking projection and engage the right arm abutment;
- and
- the locking element will cause the right arm to rotate about the right arm securing member.
