Description

IINITED STATES4 PATENT OEErcE.
WILLIAM O. WYOKOFF, OF BROOKLYN, NEW YORK.
FURNITURE-SPRING.
Specification forming part of Letters Patent N0. 51,6411, dated December 19, 1865.
To all whom it may concern:
Be it known that I, WILLIAM C. WYOKOFE, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Furniture-Springs5 and I hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings.
The nature of my invention consists in constructing that class of bed-springs which are provided with a central guiding-rod, in such manner that the bearin gs or guides for the rod shall be entirely within the spring-.that is to say, a part of the spring-whereby I provide a spring which may be used for upholstery purposes with great advantage.
In the accompanying drawings, Figure l is a longitudinal vertical section of that class of springs to which I have adapted my invention, showing its application thereto, taken in the plane of the line a: w, Fig. 2. Fig. 2 is a top view of the same. Fig. 3 is aview showing a different manner of applying my invention.
Similar letters indicate the same parts in the three gures.
A designates an ordinary double conical spring,usually termed an hour-glass springthat is, one whose coils decrease in size from the ends to the center. B is the guiding-rod running through the center of the spring', and provided with a head, c, which may be large or small, as desired. To these parts Ilay no claim,
eithe'r separately or in combination.
To construct this spring A, as well as other springs of different forms, in such manner that the guiding-rod B shall have its bearings and supports entirely within the spring, so that itneed not depend upon a slat or the like underneath or above the spring to guide it, is the object and purpose of my invention and I effect this in the following manner, which I deem the simplest, and which I think adds the least, if any, additional expense to the spring: The ends of the wire of which the spring is composed, after the spring has been fully made, before being cut off, are carried diametrically across the spring and secured to the side opposite where the bend commences. These cross-pieces are designated by the. letter b in the drawings; but before securing them to the opposite side, one or more coils, G C, are made in them at about the center of the spring.
These coils constitute the bearings for the guiding-rod B, as can be clearly understood by reference to Fig. 1.
A modification of the above is illustrated in Fig. 3. Here the cross-rod b is made separately from the spring and subsequently attached to it. The coils O O are shown in this modification; but I propose in lieu of these, if found advantageous, to make a slot or hole through the wire (it being madelarge enough at this point for the purpose) as a guide for ings illustrate the rod B as thrust through the coils O O, its head resting upon the same, and a nut, el, which is inserted upon the lower end of the rod, (before the insertion of the rod through the lower coils,) and which works upon a thread, e, cut upon the rod and screwed up tightly against the coils O of the upper crossrod. This secures the guiding-rod B to the spring but it is evident that a shoulder might be made upon the rod, and the head a, whether metal or wood, be made to screw upon the top of the rod, or the cross-rods might be passed through slots in the guiding-rod.
The advantages of so constructing a spring that the bearings for the guiding-rod shall be within the spring, or a part thereof, are many. To make myself better understood, I will refer to the spring shown in the patent of C. F. and J. W. Tillman,December 15, 1863. Therein the spring is constructed very much as the one I here illustrate, except as to the part which is my invention. In that spring a top piece, of wood or other material, is placed on the top coil of the spring, and secured there bystaples or the like. The rod is fastened into this toppiece, and not directly to the spring, and. the lower end of the guide-rod has no bearings eX- cept such as are furnished by the slat of the bedstead. i
But my improvement makes a perfect thing of the spring, and it can be used for all upholstery purposes. If it be applied to sofas, chairs, or bedsteads with sacking bottoms, the bottom coil of the spring rests upon the sacking in the usual manner, and the guide-rod B is permitted to play through a hole in the sacking when the seat is depressed.
I Wish it understood that I. lay no claim to a spring constructed as shown in the patent labove referred to-that is, I distinctly disclaim a bed-spring provided with a guiding-rod for
