STAIR-ROD.

SPECIFICATION forming part of Letters Patent No. 715,937, dated December 16, 1902.

Application filed May 17, 1902. Serial No. 107,847. (No model.)

To aZZ whom, it may concern.-

Be it known that I, FRANK S. ANDERSON, a citizen of the United States,residin g at Easton, in the county of Talbot and State of Maryland, have invented new and useful Improvements in Stair-Rods, of which the following is a specification.

Thisinvention relates to stair-rods; and the primary object thereof is to produce a com bined stair-rod and carpet-fastener which will effectually fasten the carpet in applied position against all liability of its becoming displaced and which is highly artistic in appearance, is cheap, durable, and efficient.

Another object of the invention is to provide a device of this character capable of ad'- justment to permit it to be applied to stairrequired rigidity to render the device sufti-.

ways having risers ofvarying heights.

Astill further object is to provide improved means for locking the combined stair-rod and carpet-fastener in applied position.

It will be apparent that I have further objects in viewother than theones above enumerated, as the nature of the invention is more fully understood from the following description, taken in connection with the accompanying drawings, forming a part of this specification.

The invention consists in the construction, combinations, and arrangements of parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a view in perspective of a stairway equipped with a carpet held in applied position by devices of my improved construction. Fig. 2 is a view in perspective of a combined stair-rod and carpet-fastener embodying one form of my invention. Fig. 3 is a perspective view of the adjustable hinge-section. Fig. 4c is a plan view of the latch. Fig. 5 is a plan view of my improved device, involving a slight modi fication. Fig. 6 is a plan View of one of the members, involving a further modification. Fig. 7 is a plan view of a still further modified form of my improved device. Fig. 8 is a plan view of a further modification of one of the members.

1 and 2 designate the upper and lower members of the device hingedly connected and which may be constructed of any suitable material, preferably of wire, possessing the ciently strong for the purpose of its application.

The device is adapted to be applied in parallel relation with the riser of a stairway, placing the upper and lower ends thereof in contact with the carpet to bind the same against the under side of the projecting portion of the tread and against the upper surface of the adjacent tread at a point near the riser, respectively, thereby securing the carpet in applied position. The members when constructed of wire are formed from single strands of such material, which are bent upon themselves to provide

elongated loops

3 and 4, comprising outer and inner horizontal bars '3 and 4", respectively, and the ends of which are adapted to engage and retain the carpet in position, as above described. The free ends of the strands are thence extended at right angles to the loops in parallel relation to provide links 5 and 6, which when hingedly connected provide a stair-rod and carpet-fastener of a width a little greater than the height of the average riser. The link 5 has the free ends thereof disposed at right angles thereto and in opposite directions to provide pintles 7, and the free ends of the links 6 are formed into hinge barrels 8 for the reception of the pintles 7, hingedly connecting the two members, as clearly illustrated in Fig. 5. The links are oflset or slightly curved adjacent the loops to place the links at an acute angle with relation to the loops, consequently throwing the hingeout of vertical alinement with the loops when the device is in applied position, whereby all liability of the device collapsing is obviated. In order to retain the portions of the strands constituting the links in proper position to retain the contour of the loops and the relative'positions of the hingebarrels and pintles, I provide the links with metallic sleeves or serve the same with wire, as at 9 and 10 in Fig. 5, respectively, or twist the said portions of the strands one about the other, as shown at 11 in Fig. 6, each manner The specific forms above enumerated I have found to be advantageous for the purpose, but do not wish to be understood as limiting myself thereto, as other means may be provided within the scope of my invention.

The application of the device may be explained as follows: The device being of a greater width than the height of the average riser, it is necessary to bend the members upon their hinge to the position shown in Fig. 2 to place the bars 3 beneath the under side of projecting portion of the tread and upon the upper surface of the adjacent tread, and in order to clamp and retain the carpet in position the hinge is forced inward toward the riser beyond the vertical alinement of the loops and in which position of the hinge the device is prevented from collapsing. The inward movement of the hinge is permitted through the virtue of the spring quality of the wire from which the device is constructed, consequently permitting the bar 4 to give away under pressure of the levers, as clearly shown in Fig. 1.

It may be found advantageous to provide the device with locking means to obviate any liability of the same becoming displaced as a result of great strain placed upon the carpet, which has a tendency to pull the carpet away from riser, consequently displacing the device. The locking means consists of a latch 14, in the form of a disk, fulcrumed upon the link 5 and provided with a cam-slot 15, adapted to engage a bolt 16, carried by the link 6, thereby holding the links in their relative positions when the device is in use.

In Figs. 2 and 3 means are shown for rendering the device adjustable, wherebyit may be made applicable to stairways provided with risers of varying heights. The link 6 is in this instance provided with an adjustable hinge-section 17, which is struck up from a single piece of metal and is provided at its upper end with hinge-barrels 18 for the reception of the pintles 7, hingedly and adjustably connecting the members. The hingesection is also provided on one side thereof with sleeves 19, adapted to embrace the portions of the wires forming the link to slidably and adjustably mou nt the hinge-section thereon. A slot 20 is formed in the face of the hinge-section,through which extends the head of a binding-screw 21, adapted to secure the hinge-section upon the pintle in its adjusted position. The bolt in this construction of the invention is secured to the hinge-section at a point to be readily engaged by the latch irrespective of the position the hinge-section is caused to assume upon the link 6.

In Fig. 5 I have shown a modification of myinvention having the bar 3 of the loop 3 provided with depending guides 22, adapted to direct the bar 4 in its movement when the latter is bent under pressure of the links when securing the device in applied position, and the bar 3 of the loop 4 is flattened to provide the device with a firm support to obviate any liability of the loop 4 moving when applying the device. This figure also shows the manner of serving and providing the links with collars for the purpose above described.

Fig. 6 illustrates the loop3 of myinvention having the bar 3 provided with the corrugated surface and the portions forming the link 5 twisted one about the other for the purposes fully set forth above.

In Fig. 7 I have shown a further modification of my invention involving the adjustable feature and in which form the links 5 and 6 are dispensed with and in their stead substituted a pair of connecting-levers 23, pivotally secured at their opposite ends to the

loops

3 and 4, whereby the members are connected to have a vertical movement with relation to each other. The levers are provided with a plurality of alining perforations 24:, each of which is pivotally and adjustably connected through the medium of a bolt 25, which may be moved from one series of perforations to the other to adjust the width of the device to accommodate for risers of varying heights. The lower levers are provided at a point adjacent their upper ends With laterally-projecting stops 26, adapted to engage the outer edge of the upper levers to limit their inward movement upon their pivots at a point beyond their vertical plane to obviate any liability of the levers casually turning in the reverse direction, as is clearly illustrated in dotted lines in Fig. 7, consequently rendering it impossible for the device to collapse when in applied position.

Fig. 8 discloses another manner of making the members, which consists in forming each member of separate strands of wire forming the bars 3, having their outer ends curved, as at 27, to provide smooth ends to prevent abrasion of the carpet, and the inner ends of the strands are bent at right angles to form links 5 and then bent to form the pintles 7 or the hinge-barrels 8. The strands are held in proper relation through the medium of a collar 28 embracing the portions thereof forming the links.

In order to give to the device a highly-artistic appearance, the same may be nickleplated, and the latch 10 may have struck in relief thereon any suitable design.

It is obvious from the above description, taken in connection with the accompanying drawings, that I provide a combined stair-rod and carpet-fastener which is readily and .quickly applied, will hold the carpet in a neat manner in applied position, and which is cheap, durable, and eflicient.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
