Abstract
Abstract A guide and alignment member for use in serial printing devices. The guide member makes possible a sizable increase in the number of type that may be printed in a given time frame. As the type elements approach the printing impact zone at high speed, some of them may still be oscillating from a previous impact, or may be misaligned. As these misaligned or vibrating elements move towards the impact zone, the guide member brings these elements into registry with the printing hammer. The result of this guiding process allows for greater speed of operation, since the type elements will be prevented for interfering or otherwise colliding with the striking hammer.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
187 words
A guide and alignment apparatus for use in a serial-type printing device comprising a printing hammer for impacting a plurality of type elements disposed upon a rotatable disc moving transversely of an axial impact axis of said printing hammer, said guide and alignment apparatus comprising: a base member for supporting said printing hammer for axial movement along said impact axis; and a curvilinear guide and alignment member supported by said base member in substantially adjacent relationship with said printing hammer and so disposed as to contact a number of type elements as said type elements move transversely of, and approach said impact axis of the printing hammer, said guide and alignment member comprising a section of wire which is fastened at its ends to said base, said wire curving inwardly towards said type elements and having a substantially straight mid-portion disposed transversely adjacent said impact axis of the printing hammer and contacting and supporting a number of type elements as they approach the impact axis of said printing hammer, said guide and alignment member aligning said type elements at a given set position before impact is achieved.
