SPECIFICATION forming part of Letters Patent No. 655,756, dated August 14, 1900i Application iiled November 20, 189g. Serial No. 737,565. (No model.) l
To all whom it nza/y concern:
Beit known that I, FREDERICKYBUOB, a cilizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented Acertain new and useful Improvements in Springs for Upholstered Cushions, of which the following is a speciiication.
The object of my invention is to provide improved upholstering springs particularly adapted to be applied to buggy-seats.
The features of my invention Will be more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure lis a top plan View of my invention. Fig. 2 is a perspective view of the single spring and its support.
B B represent the side frame-pieces, and C C the end frame-pieces.
The series of springs which support the cushion are composed of duplicate sections D D. The outer ends of each section are firmly engaged with the seat-frame B. They are provided at this point with a coil a and from thence toward the center are bent in zigzag,V-shaped, or undulating projections b l), forming transverse or fabric-like cushionsupports. The sections of spring thus bent are preferably advanced toward their meeting ends in arch-like form. The inner ends of the two sections have the hooks c c, which engage over a common supporting spring-rod d, thus forming a yielding joint, thereby increasing the flexibility of the spring vertically and avoiding the stiffness which would arise if the springs were all made in one piece.
It will be readily seen that the vertical coils sustain all the downward pressure brought to bear upon the cushion and that the same is distributed over a substantiallycomplete spring-surface by reason of the horizontal zigzag or undulating arrangement of the springs, so that a strain cannot be imparted to any portion of the cushion-surface Where it will not be received by a spring-bearing.
The hook engagement of the springs over a common supporting-rod at their inner meeting endsis an importantfeature,as the springs not only mutually support each other at this point, but they maintain to a certain extent independentactiomthe hooks movingupon their mutual supporting spring-rod as the springs adjust themselves to support the pressure brought to bear upon them. Again, the eX- pansion or contraction and Wear of the metal are very easily provided for by either extending or diminishing the hook portion or by detachin g the hooks and compressing or stretching the spring-coils. By this means a perfectly uniform and equal spring-bearing support is provided for the cushion, which can be maintained throughout the life of the springs, as above explained. This construction is remarkably cheap, the operation efficient, and the life of the ordinary upholstered cushion is nearly doubled thereby. 0f course the number of springs employed may be varied at will. Also the configuration of the loops and undulations may be varied, prov vided they retain the function which they are designed to form. It is also obvious that my invention can be applied to any desired style of upholstering for any purpose.
Having described my invention, I claiml. In a buggy-cushion, the combination of a rectangular frame, a plurality of springs each having a vertical coil near one end attached to the side of the frame, the springs having horizontal undulations bearing against the cushion, a loop formed in the other end of each spring, and a spring-rod over which the loop ends of said springs engage, substantially as specified.
2. In a buggy-cushion, the combination of a rectangular frame, a plurality of springs attached to the opposite sides of said frame, eac-h spring having a vertical coil near its attached end, and an arched extension having horizontal undulations bearing against the cushion, the meeting ends of the oppositelydisposed springs having loops, and a springrod over which the meeting loop ends of said springs engage, substantially as specified.
3. In a buggy-cushion, the combination of a rectangular frame, duplex springs att-ached to the lopposite sides of said frame, having independent springs, substantially as specivertieal coils near such attached ends and lied. 1o horizontal undulations bearing against the In testimony whereof I have hereunto set cushion-bottom, loops formed on the meeting my hand.
