Abstract
507,487. Holding-tools. TONDEUR, R., and TECALEMIT, Ltd. Dec. 13, 1937, No. 34506. [Class 61 (ii)] [Also in Groups XXIX, XXII, XXXII, and XXXIV] A tool for inserting springs into lubricating nipples and the like has a roughened conical or spherical head 11 and, as it is moved axially into the nipple, may either rotate to wind up the spring which thus tends to be " screwed " past the rim 7 into the casing, or move laterally to cause the convolutions of the spring to pass the rim one by one ; it may also be provided with a stop, either incorporated in its actuating mechanism or in the form of an axial forward extension engaging the ball 5. The angle of engagement of the head 11 with the spring is sufficiently above the coefficient of friction between the materials as to enable the tool to be withdrawn without force after the spring has been inserted.
