6 Claims.

My invention relates to improvements in upholstery spring anchoring means. One of the objects of my invention is to provide novel means for firmly anchoring an upright'coil spring to a seat frame, and which will permit the spring to have free vertical movement. I

A further object of my invention is to provide novel means for anchoring a coil spring, which eliminates the usual nailing to the seat frame of the tie cords used to connect together and anchor the springs of a seat, but which firmly holds said cords and greatly reduces the Wear thereof.

My invention provides further a novel hook member adapted for pivotal engagement with a seat frame and having means for engaging and holding a coil of an upright spring from pulling away from the seat frame, the hook member having novel means for preventing disengagement therefrom of the coil.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates the preferred embodiment of my invention,

Fig. 1 is an enlarged plan of my improved hook member shown attached to a portion of a seat frame and to a part of a coil of an upright spring, the anchoring cord being omitted.

Fig. 2 is a side elevation, reduced, of a coil spring shown attached to a seat frame, a part of the frame only being shown, by my improved anchoring means.

Fig. 3 is an enlarged side elevation of my improved anchoring means shown attached to a seat frame and to a coil spring, portions only of the spring and seat frame being shown in vertical section. Y

Fig. 4 is a perspective view of my improved hook and locking members and of the member which attaches the hook member to a seat frame.

Fig. 5 is a side elevation of the hook member showing, in solid lines the ring like locking member in the released position.

Fig. 6 is a view similar to Fig. 5 looking at the hook member from the inner end thereof.

Similar characters of reference designate similar parts in the different views.

1 designates generally my improved hook member, formed from a piece of wire doubled on itself so as to form a transverse horizontal portion adapted to be pivoted on a horizontal axis to the front portion 2 of a seat frame. Said horizontal transverse portion, designated by 3, is mounted in a transverse groove 4 provided at the corner of a right angled member 5, the arms of which are respectively fastened to theupper and inner sides of the frame portion 2 by nails or screws 6.

The transverse portion 3 forms one end of the hook member. The two end portions of the wire are bent to form a hooked portion 7, the extreme ends of the wire being formed into two eyes 8, in which are respectively pivoted the end portions, of a transversely divided ring like member 9, which is of a length permitting it to swing from the dependingopen position, shown in Figs. 5 and 6, to its operative position, Figs. 2, 3 and 4, in which latter position it extends across the hooked portion 7 so as to close the latter, and thus prevent the disengagement of an intermediate coil 10 of an upright coil spring 11, the lower end of which is supported in any usual manner, as by the webbing 12, fastened to the under side of the seat frame.

The length of the ring like member 9, is such that it will permit the transverse portion 3 to pass therethrough before that part is mounted in the groove 4 of the right angled member 5.

A tie cord 13 of usual type is fastened at one end to the ring like member 9 and extends therefrom to a coil of the spring 11 which is above the intermediate coil 10 to which the hook member is attached. Preferably the tie cord 13 is attached, as shown in Figs. 2 and 3, to the outer side of the top coil of the spring 11, and is then extended across said coil and attached to the opposite side of the coil, from which it is extended and attached to adjacent springs, not shown.

The ring like member 9 and the tie cord 13 form laterally flexible anchoring means, which assists the hook member in holding the spring 11 in its proper position.

By reason of the hook member being pivoted on a horizontal axis to the seat frame portion 2, the spring 11 can be depressed but will be anchored against inward movement.

In assembling the anchoring means, comprising the hook member 1, the ring like member 9 and the tie cord 13 and right angled plate or member 5, the ring like member is first swung to'the depending open position, shown in Figs. 5 and 6, after which the hooked portion 7 is provided with hooked engagement with the intermediate coil 10 of the spring 11. The member 9 is then swung v 105 over the transverse part 3 to the upwardly inclined position, shown in Figs. 2 and 3, thereby closing the hooked portion '7, and locking therein the coil 10. The portion 3 is then inserted into the groove 4, and the right angled member 5 attached to the top and inner side of the frame portion 2 by the nails or screws 6. The tie cord 13 is then attached to the member 9, and to the upper coil of the spring 11, as has been described, and to the other springs, not shown to which it is to be connected.

The ring like member 9 thus serves the double function of closing the hooked portion 7 of the hook member, and as a part of the anchoring device connected with the top coil of the spring 11. With its use the fastening directly to the seat frame of the tie cords by nailing thereto is eliminated, and much wear on the tie cords is thus eliminated.

Various modifications of my invention, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:

1. In upholstery spring anchoring means, the combination with a seat frame and an upright coil spring, of a hook pivoted on a horizontal: axis to said frame and having hooked engagement with an intermediate coil of said spring, and anchoring means attached to a coil of said spring above said intermediate coil and closing said hook for holding said coil from disengagement with said hook.

2. In upholstery spring anchoring means, the combination with a seat frame and an upright coil spring, of a hook pivoted on a horizontal axis to said frame and having hooked engagement with an intermediate coil of said spring, a member pivoted to said hook movable to andfr'om a position closing said hook at the outer side of said coil, and anchoring meansattached to said member and to a coil of said spring above saidv intermediate coil. 1

3. In upholstery spring anchoring means, the combination with a seat frame and an upright coil spring, of a hook pivoted on a horizontal axis to said frame and having hooked engagement with an intermediate coil of said spring, a ring like member pivoted to said hook so as to swing to and from a position closing said hook, and anchoring means attached to said member and to a coil of said spring above said intermediate coil.

4. In upholstery spring anchoring means, a member having at one end a transverse portion adapted to be pivoted on a horizontal axis to a seat frame and having at its other end a hooked portion adapted to receive a coil of a spring, and a locking member pivoted to said first named member so as to be swung to and from a position closing said hooked portion.

5. In upholstery spring anchoring means, a hook member having a hooked portion at one end thereof adapted to receive a coil of a spring and having at its other end means adapted for pivotal attachment to a seat frame, and a ring like member pivoted to said hook member at the extremity of said hooked portion and adapted to be swung to and from a position across and closing said hooked portion and adapted to have fastened to it an anchoring means.

6. In upholstery spring anchoring means, a hook member comprising a Wire doubled on itself to form at one end a transverse portion adapted for being pivotally attached to a seat frame, the end portions of said wire being bent to form at one end of said member a hooked portion adapted to receive a coil of aspring, said end portions being formed into two eyes respectively, and a ring like member pivoted in said eyes so as to be swung to and from a position closing said hooked portion, and in so swinging permitting said transverse portion to pass through said ring like member.
