A quadrant is a period astronomical instrument used for measuring elevation from the horizon. It consists of a graduated quarter-circle (hence the name) with a movable index and a sight; an example with heraldic interest is a horary quadrant engraved with the badge of Richard II, 1399 [Marks & Payne 35]. For related charges, see astrolabe, sphere, sundial.

A quill of yarn is a cover for a spindle, onto which thread or yarn is wound; it can then be easily removed for use. Mundanely, it’s also known as an “embroiderer’s quill”. The blazon should include reference to yarn or embroidery, to help distinguish it from a “quill pen”.
The quill of yarn is a period charge, dating to 1558 in the arms of the Worshipful Company of Broderers [Bromley & Child 31]. It’s palewise, and wound with yarn, by default. There are instances in mundane armory of empty quills, without yarn, such as the arms of von Haren, 1605 [Siebmacher 147], but the fact is always blazoned.
The “spindle” itself is also found, the winding piece of a spinning wheel. It’s drawn as a slender cone wound with thread or yarn; it’s found in the arms of Hobby, 1610 [Guillim1 204], where it’s blazoned as a “fusile upon a slipper”.
A quintain is a target for tilting practice, consisting of a post with a pivoted crosspiece, armed with a wooden shield, and often a sandbag for counterbalance. The rider would attempt to strike the quintain with his lance as he rode by; missing the shield would leave it in the rider’s path, but striking at too slow a speed would cause the sandbag to clout the rider as it swung around! Though a period artifact, the quintain does not appear in period armory; the illustration is taken from a 14th Century psalter [Barber & Barker, Tournaments, p.27].
Lorenzo Quintain bears: Argent, a quintain armed to dexter with a sword bendwise and to sinister with a shield, gules.
Philip Rufus Kennard bears: Erminois, a quintain gules and a base nebuly vert.
A quiver is a container that allows for the protection of and easy access to arrows. It’s found in the arms of Loyd, 1632 [Guillim2 336]. The quiver is palewise by default. If the quiver contains arrows, the fact must be blazoned; the illustration shows a quiver with two arrows.
Tsunetomi Todomu bears: Sable, a Japanese quiver with two arrows within a bordure argent.
Elizabeth Wingfield bears: Per pale and per chevron gules and Or, a quiver holding two arrows sable.
