BASE FOR FURNITURE.

SPECIFICATION forming part of Letters Patent No. 503,993, dated August 29, 1893.

v Applioationfiled January 26, 1893- Serial No. 459,828. (No model.)

To all whom it may concern Be it known that I, WILLIAM D. SNYDER, 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 Bases for Furniture, of which the following is a specification.

The object of this invention is to construct a base upon which may be located combined furniture, for instance, a combined book case and bed or other various combinations, or in which both sides may be the same, for instance, a double sided book case, said base composed of a stationary part, having a portion movable and an upper part having a pivotal connection with the movable portion and also an engagement with the stationary portion during a portion of the rotation of o the upper portion, so that by moving the upper portion upon its pivot will also movethe portion of the base carrying the pivot outward, in order that the upper portion may be turned about, that is the rear face brought to the front.

In the accompanying drawings-Figure 1 is an isometrical representation of my improvements in their closed or normal positions. Fig. 2 is an isometrical representation of the same, in which the upper portion is turned upon its pivotal connection with the base. Fig. 3 isan isometrical representation showing the under side of the upper portion and the upper side of thebase and in which the track or movable support is in its normal position. Fig. 4, is an isometrical representation of the upper face of the base showing the track extended. Fig. 5, is an isometrical representation showing the under face of the track and the upper face of the base. Fig. 6, is a transverse section through the roller supports for the track in its closed position. Fig. 7, is a similar view in which the track is extended.

In the accompanying drawings, the base is composed of ends 1, connected by lengthwise bars 2 and 3, and cross pieces 4 and 5. The upper face of the base portion is provided with a depression or recess 6, having its inner end enlarged. The cross pieces 4 and 5 have their upper faces provided with a track 7, having its end near the rear face elevated, and is also provided with a grooved trackway 8, having its rear end elevated. Grooved faced rollers 9, are located upon the track 8.

Within the space between the ends of the base is located an extension 10, having secured to its under surface tracks 11, and grooved rollers 12, projecting below its lower face and from the forward end extension depends a cross bar 13, having rollers 14, secured in its lower face. A stop 15, is also secured to the under side extension. When the extension is in position between the ends of the base, the rollers 12, will lie upon the tracks 7. A portion of the bar 2, is cut away in order to permit the withdrawal of the extension. Recesses 16, are formed in the rear bar 3, which receives the projecting ends of the extension. By reference to Figs. 6 and 7 it will be seen that when the extension is in its closed position the rollers 14, secured to the front lower end of the extension are elevated some distance above the floor and when the extension is withdrawn the rollers 12, secured to the rear end of the extension will run upon the track 7, from its highest end to the lowest end near the roller 9, which is of the traveling nature, will run from the highest part of its track to the lowestpoint which will permit the extension to descend until the rollers secured to the front end of the extension comein contact with the floor as shown at Fig. 7. Itwill be noticed that the upper face of this extension, during this movement, stands at a horizontal line or has a parallel movement, which is owing to the inclined tracks 7 and 11. In the upper surface of this extension are located three rollers 17, which project slightly above its face and is also provided with a central stud 18.

The under surface of the roller port-ion or platform 19, has secured thereto a circular track 20, a bushing 21, and aroller 22. When this platform is placed in position the central stud 18, will enter the bushing 21, and form a pivotal connection between the platform and the extension, and when the .plat form is in its closed position the roller 22, will lie in the straight portion ofthe groove 6. The operation of my device is as follows:

The platform being mounted in position upon the extension the circular track will lie upon the upper face of the roller 17. The operator by taking hold of the corner 23, of the platform draws out upon it which will move the extension outward by reason of its pivotal connection therewith, and by reason of the roller located in the straight portion of the slot 6, and a continued movement will bring the extension to its outermost position as shown at Figs. 2, 4 and 7, and at this point the roller will become disengaged from its connection with the slot and the enlarged portion of the slot will permit the platform to be turned upon its pivotal connection with the extension until the platform assumes its position shown at Fig. 2, and should the platform be continued in its movement the roller will engage the surface of the slot in the other end of the platform, which will then slide in the slot and draw the extension to its original position when the platform will be turned completely around. The stop 15, on the under side of the extension will engage the rear face of the bar 2, which will prevent the further movement of the extension.

Upon the upper surface of the corners of the base and the under surface of the corners of the platform are secured wedged blocks 24, which serve to steady the platform in its closed position.

It is evident that any combination or article of furniture can be mounted upon my improved base and still be within the meaning of my invention.

Instead of making the platform a separate part, the circular track and other parts secured to the under face thereof, may be socured directly to the under face of the article of furniture used in connection with the base, and when a folding bed is used as a part of the combination the folding bed may be lowered for use when the platform has assumed the position shown at Fig. 2, that is the platform is turned completely around, and the roller 22, may be pivoted to the opposite end of the platform, which will permit the turning of the platform in the opposite direction.

So far as known to me I am the first to provide a platform upon which can be mounted a combination article of furniture, which by the act of turning the platform will at the same time move its support so that the support will always be under the center of the combined article of furniture, whatever position it may assume.

I claim as my invention-- 1. A base for furniture provided with straight recesses extending only a portion of the length of the base, inclined tracks extending transversely of the base, an extensible section located upon the tracks, a platform having a pivotal connection with the section, and a roller engagement with the recesses of the base during the movement of the section.

2. A base for furniture provided with straight recesses extending only a portion of the length of the base, inclined tracks extending transversely of the base, an extensible section, inclined tracks secured to the under face of the extension, the extension having a roller engagement with the tracks, a platform having a pivotal connection with the section and a roller engagement with the recesses of the base during the movement of the section.

3. A base for furniture provided with straight recesses extending only a portion of the length of the base, inclined tracks extending transversely of the base, an extensible section located upon the tracks, a platform having a pivotal connection with the section through the medium of a series of rollers located in the upper face of the extension and an annular ring located upon the rollers and secured to the under face of the platform, said platform having a roller engagement with the recesses of the base during the movement of the section.
