racks Rand R are eachp'ivota'lly engaged adjacent'one end portion to the head, as

indicated at 5, but in reverse arrangement.

As herein embodied the upper rack. R. has its end portion adjacent the rod P pivotally mounted, while the lower rack R has its end portion remote from the rod P ivotall 'moimted. The free'e'nd portiono each'o the racks R and R has bearing thereagainst a fiat spring 6, for constantly urging the rack toward the limit'of its inward movement, and which limit of inward movement ise controlled by a laterall I directed finger 7, carried by the free en portion ofthe rack and overlying the adjacent ed e of the r as particularly illustrated in Fig. 6. Each of the springs 6 is anchored tothe head H adjacent thepivoted end portion of the rackllwith which said spring coacts, as
