IMPROVEMENT IN BEBOTTOMS.

Specification forming part of Letters Patent No. 136,382, dated March 4, 1873.

To all lwhom 'it may concern:

Be it known that we, HARRIsoN OGRORN, of Richmond, Indiana, and ANDREW W. KEN- DRIOK, of the city of Brooklyn and State of New York, have invented a new and useful Improvement in Bed-Bottoms; and we do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to ina-ke and use the same, reference being had to the accompanying dra-wing forming part of this specification.

Figure 1 is aplan view. Fig'. 2 is asectional view of the inner side ot' the rail. Fig. 3 is a detached view. Fig. 4 is also a detached view. Fig. 5 is an inside view of the slat-iastening. Fig. 6 is an end sectional view, showing a single slat. Figs. 7 and 8 are sectional views of the head-rest. Figs. 9 and 10 are sectional views ofthe double and single slats.

The object ot' this invention is to furnish a very elastic, easily-constructed, and economica-l bed-bottom; and it consists in the peculiar form of the levensprings, the manner ot attaehing them to the cross-bar and to the slat, the frame and slats forming the head-rest, and the slotted ratchet by which it is opera-ted.

We prefer to make our bed-bottom of double slats, and for that purpose we form the stil:- rup end of the spring with a projection or elevation in the center, whereby a seat or rest is made for the slats. By this means two slats are placed upon each spring. The slats are necessarily and preferably very light and elastic, and therefore require a thin mattress. When a single slat is used it is broader, a fewer number are required, and the bedbottom is less expensive, and the elevation in the spring is dispensed with.

The manner of attaching the springs to the cross-bar we consider an improvement over the usual method. We pass the free end of the coils up through the bottom ofthe ba-r, bringing the coil behind and against the bar, and clinchin g the end of the coil on the upper side of the bar. For greater security a staple is driven into the under side ot the bar, to hold slats, making an irregular surface for the mnttress.

For attaching the. slats to the springs we use new device, which consists ot' a metallic bar with a button on each end.. The bar alittle longer than the slat is thick and is nearly square. In constructing this slab-holder the bar and one of the button-heads are cast together. Upon the free end ot' the bar there a shoulder. The other button is cast separately. The bar is passed through the slot in the slat, and the second button is riveted upon the shoulder of the bar. Thus a tirni clasp is furnished, into which the end ot' the stirrup of the spring is inserted. rlhe bar, being square, cannot turn in the slat, nor get out of place. The slats are readily reversed without removing the holder or clasp or changing its position.

'The head-rest is so constructed that it can readily be detached. The side frames are pivis attached to the lower end of the head-rest.

slat, which passes through a slot in the slat ot' the bed-bottom, where it is turned and serves as a clasp. In the head-bar ot' the head-rest a gain is out, which is inclosed by a staple, into which the top ot' the short slats are inserted. The head-rest is operated by a slotted pawl and ratchet, which are detachably attached to the frame of the bed-bottom. rlhus it will be seen the head-rest and thedevice for operating it can all be taken ot'f when they are not required.

There is a peculiar advantage in having thc slotted ratchet and ypawl. By this constructionvthey are held in place, the guard acting as a guide and as a protection to the'tecth. The pin with which the teeth engage is located between the guard and the teeth, and when the head-rest is operated b y the cord the height is adjusted regulerl5r andvgrztdually. v

In the drawing, A A represent the side rails; B B, the cross bars; G, the slats; D, the springs; N, the projection on the stirrup of the springs. E is the head-rest; F, the slotted ratchet; M, the pin. G- is the button-head to the spring-clasp; H, the connecting-bar. I is the piu by which the head-rest is pivoted to the side ruil. K shows the hook on the bottoni ofthe head-rest slet. L is the mortise in the main slet through which it passes. M is the pin with which the ratchetteeth engage.

Having described our invention, what we claim, und desire to secure by Letters Patent, 1s-

1. Constructing the lever-spring; with e projection upon the end ot' the sti-rrup, on either side of which seats ure formed for the double slats, as described. Y

2. The springs with the coils behind und ou u level with the cross-bur, und passing the end of thc wire up through the bottoni ot` the bur und elinching it 011 top of the bar, as described.

3.`Tl1e spring-clasp, formed by wbutt'on upon each end of it bar, as described, 'and for the purposes set forth.

4. The head-rest, pivoted and keyed to the side rails, the short sluts at the lower end hm'- ing hooked Wires clasped through slots in the main sluts, and resting` in gains inclosed in staples et the upper end, as described.

5. The ratchet and puwl, constructed with a. guard and operating as described.

6. The combination ot the sluts, the leversprings, the slet-clasp, the head-rest, und the slotted pewl, all constructed us described, mul for the purposes set forth.
