SPRING-BOTTOM FOR FURNITURE.

SPECIFICATION forming part of Letters Patent No. 746,769, dated December 15, 1903- Application filed November 17(1902. Serial No. 131,704. 7 (No model.) I

To aZZ whom it may concern:

Be it known that I, WILBERT E. WHITTE-' MORE, a citizen of the United States, residing at Waterville, in the county of Kennebec and State of Maine, have invented a new and useful Spring-Bottom for Furniture, of which the following is aspecification.

The invention relates to spring-bottoms for bedsteads, couches, carriage-seats, and similar articles, and particularly to means for supporting double-cone springs to maintain them in the desired relative positions, prevent creaking, and otherwise insure efficient service and durability.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

In the drawings, Figure l is a plan view of a spring-bottom constructed in accordance with the invention. Fig. 2 is a detail view showing a spring-seat on a supporting-frame. Fig. 3 is a detail sectional view of adjacent members of the frame on the line 3 3 of Fig 1.

Similar reference characters indicate corresponding parts in all the figures of the drawings.

Within a suitable frame 1, of a shape, size, and material adapted to'the particular article with which the spring-bottom is to be used, are arranged a series of intersecting

springsupporting elements

2 and 3. In the construction illustrated the longitudinal supporting elements 3 consist of flat bars or strips disposed vertically edgewise, headed or otherwise secured, as at at, to one of the end members of the frame and provided at'the other end with an opening, with which is engaged a book 5 of an adjusting device 6, engaged with the other end of the member of p the frame, the tension of the supporting-frame 3 being adjustable by means of the nut forming a part of the adjusting device. The member 3 is provided with openings, through which pass the other spring-supporting members 2, whereby said supporting members are located slightly below the planes of the upper edges of the members 3 and are terminally attached to the adjustable bars 7, secured, respectively, to the side members of the frame 1 by means of set-screws 8. The fiat springsnpportiug members 3 are also provided on opposite sides of the plane of each intersecting member 2 with'perforations 9 for the reception of the lower coil of the spring 10, said lower coilbeing threaded through these openings, as clearly indicated in Fig. 2. Interposed between the perforations 9 and engaging the upper edge of the flat support 3 is a saddle 11, of leather or other yielding material, with its side wings or flanges extended downward and perforated in alinement with the openings in which the spring-supports 2 are arranged. Thus the saddle is held in place by the rods 2 and occupies the entire upper surface of the member 3 between the opposite sides of v the coil of the spring, whereby the adjacent coils in the use of the spring are cushioned by the saddle, and thus are prevented from coming in contact with the edge of the metallic strip 3 and causing creaking, rattling, or other disagreeable sound.

The above-described construction provides for the use of double-cone springs without the disadvantages incident to the ordinary means of mounting, and at the same time provides for maintaining the supports at the desired tension to prevent sagging of a portion which is subjected to an unusual amount of strain. The parts-are readily assembled and may be separately replaced when needed at small cost and without resorting to skilled labor.

Having described the invention, what is claimed is 1. In adevice of the class described, a frame comprising side members, end members, auxiliary side members, longitudinal supporting elements consisting of flat strips disposed vertically edgewise and connected permanently with one end of the frame, means for connecting the opposite ends of said strips adjustably with the opposite ends of the frame, said longitudinal supporting elements being provided with transverse perforations disposed in series of three, saddles engaging and supported by said longitudinal supporting members and provided with side wings engaging the sides of the latter and terminating short of the two outer perforations of each series,transverse supporting elements extending through the side wings of said saddles and through the central perforation of each series in the longitudinalsupporting elements and connected at their ends with the auxiliary side members of the frame, means for connecting said auxiliary side members adjustably with the main side pieces of the frame, and double-cone springs having their lower coils threaded through the perforations in the longitudinal members at the ends of the saddles.

2. In a device of the class described, a frame, longitudinal supporting elements consisting of flat strips disposed edgewise in said frame, saddles engaging and supported by said longitudinal supporting members and provided with side wings engaging the sides of the latter, and transverse supporting elements extending through perforations in the longitudinal supporting elements and through the side wings of the saddles.

3. In a device of the class described, a longitudinal supporting element consisting of a flat strip disposed ed gewise and provided with three perforations in proximity to each other,

in combination with a saddle supported upon said strip between the outer perforations and having side wings engaging the sides of said strip, a transverse supporting element piercing the side wings of the saddle and extending through the perforation in the strip covered by said side wings, and a spring having its lowermost coil in engagement with the perforations at the ends of the saddle and its second coil supported upon said saddle.

4. In a device of the class described, a supporting element, a saddle resting upon and engaging the sides of said supporting element, a secondary supporting element piercing the side wings of the saddle and the strip confined between said sides, and a spring having its lowermost coil in engagement with the primary supporting element and its second coil supported upon said saddle.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

WILBERT E. WHITIEMORE.
