UNITED STATES MICHAEL NATHANIELJ'ACOBSON, 0F EGCLES, MANCHESTER, ENGLAND.

STAIB-CARPET HOLDER APPLICABLE FOR OTHER PURPOSES.

Application filed July 18,

To all whom it may concern:

Be it known that I, Mioinann NATHANIEL JACOBSON, a subject of theKing of Great Britain and Ireland, and resident of Eccles, Manchester, in the county of Lancaster, England, have invented certain Improvements in Stair-Carpet Holders Applicable for Other Purposes, of which the following is a specification.

This invention relates to improvements in devices for use in keeping stair carpets in position, though it is applicable for other purposes and as regards its connection with stair carpets has reference to the type of device consisting of an arm pivoted to the riser or tread of the stairs so as to be capable of being turned into position for holding the carpet at one edge and to be turned out of position to enable the carpet to be taken up, devices of the aforesaid kind being employed in connection with both edges of the carpet.

In the aforesaid known type of device the arm is merely pivoted at one end on a screw secured in the riser or tread of the staircase whilst its free end is turned about such pivot so as to lie in front of the carpet opposite the riser of the staircase.v No pro vision is made for preventing the tension on the carpet moving the arms more or less out of position.

The object of my invention is to provide an improved form of device which can be secured either to the riser of the staircase or to the tread of the latter and in both cases can be held firmly in position against any tension or pressure which may be put upon the carpet. To this end my invention consists of a bracket adapted to be attached to the riser or to the tread of the staircase, an arm pivoted to the bracket and a catch device for holding the arm securely in position.

My invention will be fully described with reference to the accompanying drawing in which,

Fig. 1. is a front elevation of the device shown secured to the riser of a staircase and Fig. 2. plan of same.

In accordance with my invention I provide a suitably-constructed bracket a which may conveniently be of substantially rightangled cross. section looked at in end elevation so as to fit snugly in the corner or jnnction of the tread b and riser 0 of the stair- 1923. Serial no. 652,318.

way. This bracket is provided with holes (Z, through which screw 6 or the like may be passed to attachit either to the riser or the tread or to both. To the horizontal portion f of the bracket,preferably, I pivot one end of a short arm g the pivot It being vertical so as to enable the arm to be turned into and out of holding position. The arm 5 is sufficiently long to project a sufficient distance over the carpet 2' at one edge to securely hold it in position, and to prevent any tension or pressure on it moving the arm 9 out of holding position I employ a catch device which may conveniently consist of a short arm j pivoted at 73 at the vertical portion m of the aforesaid angle bracket, the free end of such arm j engaging with the front portion of the main arm 9. The latter can be turned out of using position by first lifting the catch or arm y.

The main holding arm 9 may be arranged on a horizontal pivot if desired so that it may be turned into and out of position about such pivot, a corresponding catch device being employed for holding it in position as before.

The main arm is preferably though not necessarily of right-angled cross section so that it may fit snugly in the corner formed by the carpet. It is also preferably tapered from the pivotal point to its free end so as to give considerable strength to resist any strains which may be put on the carpet.

I may use any other suitable form of catch device in conjunction with the main arm.

This fastening device may be used for other purposes besides fastening stair carpets to stairs.

What I claim is:

1. A fastening device, comprising an 'angle-shaped supporting bracket, a fastening arm pivoted in the angle of the bracket to one of its parts and projecting at one end thereof and adapted to engage with the article to be fastened, and a retaining catch carried by the other part of the bracket and operating to clamp the said arm against the part of the bracket to which it is pivoted.

2. A fasteningdevice as set forth in claim 1, in which the retaining catch is formed of an arm which is pivoted to the part of the bracket which carries it.

In testimony whereof I have hereunto set my hand.

MiCHAEL NATHANIEL JACOBSON.
