Specification ofLetters Patent.

Application filed February 12, 1917. Serial No. 147,994. 7

To all whom it may concern Be it known that I, CORNELIUS Gianna subject of the King. of Great Britain and Ireland, and residing at 12 Tasker street,

have invented an Improved and Useful ing is a specification.

This inventlon relates to improvements 1n object to provide an improved device of'the slotted bar and turn-button formof such fastener. I

According to this my invention the stair carpet fastener comprises a rail orbar of any suitable section notched at one orboth ends. Each notch is adapted to receive a support which prevents lateral movement of the notched end of the rail orrod when the said pillar part is in place. Attached to the said support, so that it can be moved about its axis, is an arm adapted to engage a notched endof-the rail or bar to prevent its movement axially of the said support. ,Provision is made for preventing the movement of the arm axially of its support andalso for securing the said'supp'ort in place. 7

In the accompanying drawings, which illustrate one form of this my invention,

Figure 1 is a part front view of a stair carpet fastener made in accordance with this invention, and l i Fig. 2 is a part plan thereof.

This embodiment of my invention is shown as comprising three parts, a rail or bar a a1id two supports 6, b." The rail .or bar a is' employedto hold the stair carpet at the foot of a stair-riser in place of the well Q p 0 of said rod, aplllar adapted to engage each known rod. The flat rail or bar a, when in place is parallel to the face of theriser and v I .trensversely thereof, a rotatable arm pivotedaxially upon said pillar and adapted to prevent movement of said rod axially is retained in position there by means of swinging arms 0, 0, each carried by a short (Z. For fixing the supports 6, b in place, I

preferably on the riser as shown in Fig. 1, each pillar d is provided with a flange it having holes through which screws may be driven into the said riser.

When the stair carpet is in place itis retained in position behind the rail orbaro,

prevented from releasing it by the arms c, c,

which then occupy the positions shown on the riglithancl side of Fig. 1, and'in broken I lines in Fig. 2. The carpet is thus not liable Walsall, in the county of Staiford, England,
