SPRING.

SPEGIFIGATION forming part of Letters Patent No. 71 ,225, dated November 25, 1902.

Application filed February 27, 1902, Serial No. 95,884. (No model.) I

To all whont it may concern..-

Be it known that I, Moses H. NABER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Springs, of which the following is a specification.

The object of my invention is to provide an improved spring adapted for use in all structures which contemplate the employment of springs where it is desired to provide a yielding connection between alower base and an upper body of any character whatever; and my invention consists in an improved form of spring adapted to be employed in such relation and location.

lVhile it will be apparent from the accompanying disclosure of my invention that its range of use is not limited to any special class of structure, such as chairs or seats, I have illustrated its application and use in connection with chairs as a convenient type of device to which it is well adapted.

In the accompanying drawings, which illustrate exemplifications of my invention, Figure 1 is a side View of a chair provided with springs constructed in accordance with my invention. Fig. 2 is a top plan view of the base of the chair of Fig. 1. Fig. 3 is a bottom plan or inverted view of the chair-body of Fig. 1. Fig. 4 is a side view of a chair provided with a similar form of spring to that of Fig. 1, but with the direction of the wings reversed. Fig. 5 is a top plan view of the form of spring employed in the construction shown in Fig. 1. Fig; 6 is a side view of the same, and Fig. 7 is a top plan view of a similar form of-spring having the coils extended in opposite directions.

In the drawings, A designates achair-body or seat-frame, and B a base, which may be of any desired construction, and exemplify the upper and lower portions of a structure between which an elastic or yielding connection is provided by the springs of my invention.

The springs are made of steel wire and are arranged and disposed between the base and the body in any manner suitable to the use for which the structure is intended. For example, in the application of the springs to chairs, as shown in the'drawings,the springs are placed oppositely at the 'front and rear.

The springs are sectional in construction, and the section sof each spring is formed from a suitable length of wire consisting ofa horizontal cross-piece 1 of a length suitable to the size of the structure with which the springs are to be associated. At the opposite ends of the cross-piece the wire is slightly bent in an angular direction, as at 2, and is then extended laterally to formthe legs 3, which are substantially in the horizontal plane of the cross-piece 1. At the ends of the legs the Wire is bent downwardly to form wings bearing upon the structure and to furnish means for attaching the springs thereto. In the preferred form of this exemplification the end of each leg 3is developed into one or more vertical coils 4, which preferably are angular to the legs and extend in the same general direction as do the angular portions 2. The wires in extension of the coils at the lower portions thereof are directed inwardly toward each other to form the arms 5 and terminate in wings 6, which bear upon the frame of the structure. The wings are formed by curving the wire into suitable shape to provide an extended bearing-surface, and theinner ends of the wire are bent around the arms 5 and extended to the center of the wings, where they terminate in eyes 7 to receive attaching-bolts, to which the nuts 8 are secured. Each of the portions .9 of each spring is formed with a wing 9, similar-in all respects to the wings 6 of the portion 3, and the wire extends laterally in the plane of the wing to form outwardly-directed arms 10, which preferably are developedinto one or more vertical coils 11. The wire extends inwardlyfrom the coil at the lower portions thereof to form the leg 12 and is then coiled one or more times about the cross-piece l, as at 13, the end being coiled, as at 14, about one of the angular portions 2 of the section 3, whereby the displacement of the section 5 from its position upon the crosspiece 1 is prevented. The coil 14 also limits the torsional effect or movement of the arms and legs. It is understood that two sections 3 are employed, one at each end of the continuous section.

The wings of the sections are lateral to the line of the cross-piece or to the center line of the unitary structure and the wings of the sections 5' on the opposite side of this central line with relation to the wings of the other sections. The wings of the assembled sections are in horizontal planes difierent from that of ,this central line or cross-piece and respectively on opposite sides thereof, the separation of the wings being regulated by the size of the coils 4 and 11, whereby the body and base are supported out of contact to allow the movement of the former relative to the latter.

The coils 11 of the sections 8 may be extended in substantially the same direction as the coils 4 of the portions 3, as shown in Fig. 5, or they may be extended in an approximately opposite direction, as shown in Fig. 7, to form divergent coils. With the latter form it is found in practice that the body has more sidewise yield or movement and also an easier perpendicular action, while the former is best adapted where a forward-and-back or rocking action is desired.

In assembling the springs upon the body and base of the associated structure the continuous section 8 is preferably employed as the lower or base member, which is secured to the base by means of suitable bolts b, passing through the openings Z) and the eyes 7. The sections 3' are then secured to the bodyA by bolts a, passing through the openings a and the corresponding eyes of these sections. The springs may be assembled with the wings of the base-section s intermediate the cross-pieces and with the wings of the sections 3 relatively Widely separated, as in Fig. l, or the wings of the sections .9 may be reversed with reference to their crosspieces and be arranged outside the area there of and with the wings of sections 3 relatively nearer together, as in Fig. 4. The wings form extended bearing-surfaces and are clamped tightly against the associated parts of the base or frame by the passage of the wire around the arms 5 and 10, whereby the strain is distributed around the periphery of the wing. I

The springs may be set near together or far apart to provide for use in structures of various sizes, it being understood that the exemplification shown in the drawings and herein described is employed merely to demonstrate the general purpose of the use of the invention between any suitable base and superimposed frame to which it is desired to give a yielding motion. By setting the wings nearer together the body is given an easy and uniform rocking movement, as for chairs, &c., and by separating the springs this motion is converted into a less curvilinear motion.

Having described my invention, I claim-- 1. A spring consisting of a continuous section having a cross-piece provided with angular ends, wings lateral to the crosspiece and in a different plane therefrom, and sections each having a wing and interlocking with'one of the angular ends of the crosspiece.

2. A spring consisting of a section having a cross-piece provided with angular ends, lateral wings at the ends thereof, and a section secured to each angular end of the crosspiece and having a wing, the wings extending inwardly and the wings of the first section being on the opposite side of the cross-piece with relation to the wings of the other sections.

3. A spring consisting of a section having a cross-piece provided with angular ends, wings on the cross-piece, and vertical coils between the wings and ends, and sections each having a wing and upper and lower members with intermediate vertical coils, the end of the wire of each section being mounted on the cross-piece and bent about one of the angular ends.

In testimony whereof I affix my signature in presence of two witnesses.
