My invention rel'atesto an improvement in thereof may readily be connected to the resilient bottoms for upholstered furnitures helical springs C or S-shapcd hooks E, thus such as chairs and couches, andmore particuconnecting the rails 2--2 with bottom 4. larly to connecting devices and means for at- These hooks E are preferabl employed for 5 taching and supporting a yieldingbottom connecting the front edge 0 the bottom to 85 within a chair or couch frame preliminary to the front rail 2 in order to impart a degree upholstering the same.

The ject of my improvement is to provide looped main body portions 6 of the member D are attachment means which may readily be closely related to each other to permit insleeved through openings in the wooden sertion of these portions through relatively frame or rails and automatically interlocked small openings 7 in rails 22 through which with the outer face of the rail by attaching, openings body portions 6 are inserted from the yielding bottom to the looped portions the outside of frame A, so that oppositely thereof in a stretched state.

As stated above portions 6 under variations in tension on these connecting looped end portions will be induced to shift laterally of each other and thereby decrease or increase the size of the looped ends 5. Too great decrease in the size of such loops may create a binding action between said loops and the hook ends of springs O or Sshaped hooks E. To avoid such action I show in Fig. 4 a modified form of an attaching device D in which the body portions are twisted near the outer ends thereof at 9 to effect increase in the size of loop 5, with consequent increased tension on device D.

The connecting devices described enable the building and installation of a yielding bottom in chairs or couches rapidly and permit use of shorter springs with larger exible sheets of textile fabric without decreasing the spring action and flexibility of the yielding base by reason of the fact that the yielding members D extend through the rails. The arrangement permits use of smaller and cheaper springs and also provides a slight spring action at the front rail.

\Vhat I claim, is: p

1. A chair or couch frame having, or being provided with, a series of openings in the rails of said frame, a yielding bottom supported within said frame, and a series of looped attaching devices extending through said openings and connecting said bottom with said frame, each of said attaching devices including a looped main body extending through one of said openings into the inside of said frame and resilient branches inclined at an acute angle to said main body, the free ends of said inclined branches engaging the outside face of said frame for resilient connection of said bottom and frame.

2. A chair or couch frame having, or being provided with, a series of openings in the rails of said frame, a yielding bottom supported and stretched within said frame, and

a series of resilient and looped attaching devices connecting said bottom with said frame, each of said attaching devices including a looped main body extending through one of said openings into the inside of said frame and resilient branches inclined at an acute angle to the main body of said device and seated with their outer" ends upon the outside face of said frame for resiliently connecting said bottom and frame.

. 3. A chair or couch frame having, or being provided with, a series of openings in the rails of said frame, a yielding bottom supported Within said frame, and looped attaching devices connecting said bottom with said frame, said devices engaging the outside face of said rails and extending with their looped ortions through said openings into the insi e of said frame, and each of said attaching devices including a looped main body portion having closely related straight legs and oppositely arranged pointed branches inclined at an acute angle to said legs and seated with their pointed ends upon the outside face of said rails to permit longitudinal shifting of said looped main body within its opening.

4. An attaching device for resiliently connecting a yielding bottom to a chair or couch frame, comprising a steel wire bent to form a main body portion having closely related straight legs and a loop portion, and oppositely directed branch portions arranged at an acute angle to said legs. I

5. A chair or couch frame having, or being provided with a series of openings in the rails of said frame, a yielding bottom supported and stretched Within said frame, resilient attaching devices seated against the outside face of said rails in alignment with said openings, and short helical springs connecting said yielding bottom with said resilient attaching devices, each of said attaching devices including a main body portion axially aligned with one of said openings and oppositely directed branches inclined at an acute angle to said main body portion and engaging with their free ends the outside face of said frame to permit axial shifting of said main body portion under varying stresses.

In testimony whereof I aflix my signature.

JACOB KRONHEIM.
