Another object is to provide an upholster-' ers button and piercing-pin adapted to be used in connection therewith. I accomplish the objects of the invention in the manner illustrated in the accompanying drawings, wherein similar letters'of referonce refer to and indicate like parts throughout the several views. The invention consists in the matters heremafter set forth and more particularly pointed out in the a pended clalms.

In the drawings igure 1 is a longitudinal central sectional view of the parts composing my new button, the several parts being somewhat separated along the1r axial km for convenience of illustration; Fig. 2 is a similar view the parts of the head in assembled condition orrelation; Fig. 3' is a sectional view of the button rovided with a piercing tool seated in the ower end of the. tubular shank, and Fig. 4 is a sectional view of a completed cushion provided with my new buttons.

In carryin outmy invention I employ a hollow tubu ar or cylindrical shank A of suitable shape and size and formed of sheet metal. The shankis provided at one end with an annular flang e'a, of one or a'plurahty of p'1eces and a cap-seat B formed usually of a metallic dlsk'ls provided with a central erforation adapted to pass over the shan so thatthe cap-seat may be brought against ghe lower face of the flange. a as shown in shape of a sk corresponding in general contour with the disk is adapted to be seated L.
