Etymology: < French récipiangle (1622 or earlier), apparently < recipi- (in classical Latin recipient- , recipiēns , present participle of recipere receive v.; compare recipient n.) + French angle angle n.² Compare post-classical Latin recipiangulum (1721 or earlier).Compare earlier recipient-angle (compare also quots. 1755 and 1973; < recipient n. + angle n.², after French récipiangle):1723 E. Stone tr. N. Bion Constr. & Principal Uses Math. Instruments iii. 105 There are several Sorts of Recipient-Angles [Fr. Recipiangles ou Mesurangles], but the best and most in use, are those whose Description we are now going to give.

History of Science.

An instrument for measuring or marking off angles consisting of two arms pivoted about a common centre, each with sights, and a protractor or graduated arc against which the arms can be moved.

1728 E. Chambers Cycl. (at cited word) The recipiangle is..usually very simple; in Form of a Square, or rather a Bevel; consisting of two Arms or Branches, rivetted together, and yet moveable, like a Sector on the Centre or Rivet.

1871 H. Barnard Sci. & Art 598 The students practice determining mineral specimens and crystalline forms by means of the soldering-pipe, recipiangle, and polarization apparatus.

1939 Nature 22 Apr. 673/2 The seventy objects which comprise Mr. Court's most recent benefaction include an Italian recipiangle of about 1600.

1973 Isis 64 422/1 In the technical translation I found unpalatable only the term recipient angle for the instrument which is much more familiar as a recipiangle.
