IMPRovnn BEDSTEAD.

The kSchedule referred to in these Letters Patent and making part'of the lame.

To all whom it may -concern.

A Be it known that 'DAVID MANUEL, of Dedham, in 'the coun'ty of Norfolk, and State of Massachusetts, has invented new and useful Improvements on Spring- Bottom Bedsteads; and we do hereby declare that the ibllowing' is a full,'clear, and exact description of the construction and operation of the same, reference beingliad to the accompanying drawings, making a part of this specification, in whichv Figure 1 is a perspective view of the bedstead when together, two ofthe slats being removed to show the head and foot cross-bars B, which bars support the springs and bearings on which the slats rest, and also their connection with the rails of the bedstead, on which they also exert an influence transmitted to the fasteners, as will be shown.

Figure 2 is au enlarged View, in part, of the same.

B, a cross-bar. l

(l, the box afixed. to the rail A.

D,the inverted conic springs.

E, the bearings.

F, a slat, attached at one end to the hearings by its embracing bracelet f.

El shows a bearing in position.

E?, the same, turned up on its hinged spring-support G, showing the shoulder ou the underside, against which the bracelets j' set, and the edged terminus with its corners rounded, so as' to be readily slipped under the loop of the bracelets, which latter are held by staples s, driven over them on the edge of the slats F. Figure Gshows the metallic rod when bent. A hole is Ibored horizontallyacross the centre of the bearings through which therod is inserted to g. f The projecting ends are then bent, as shown, and applied by driving the lower points into the inner side of the cross-bars, as shown, resting on and partly embracing them.

Figure 3 is a profile view of the combination and arrangement of the'same.`

Figure 4 is an enlarged view of the open'boX c, for

the support ofthe endsof the cross-bars B. The top 3 is at right angles to the back of the box, and rests on the upper surface of the rails, having a sharp point,

1, which, with a stroke of the hammer, is driven into the rail on its top. The back of thebox is also pro,` vided with two or more of such points 2, made in the casting, which, by another stroke of a hammer, are driven4 into the innerside of the rails, and thereby allixed as firmly as if securedby screws, at a great saving of time, labor, and expense. y

Figure 5 is a view of the single coniccoiled spring D, having its apex d centrally prolonged, byv which it is inserted into a hole, a series of which is made, centrally, at regular intervals, along' the' upper side of rail, and on the propersides of the posts.

the cross-bars B. In this invert-ed position, with the broad base coiled so as ,to be horizontal, on which base rests the bearing, steadiedby its' side supports G, being both a hinge and additional spring, as Well as a support, requires no webbing or binding to support the springs, they being found admirably adapted for this and similar' purposes, and easily made and applied.

Figure "6 shows the piece'or casting H, inserted into the ends of the rails, and its counterpart K insel-ted into the post, detached.

Figure 7 shows them when inserted into their iespective places.

Figure 8 shows a front View of the post and piece K inserted, its outer face M M ush -with the wood.

Figure 9 is a-vertical section, full size, of the two pieces, locked.

The projecting point of H being provided with a tongue,-L, to fit into the slot'N on K, partly overlapping it, requires a portion of the post, centrally above, to be taken out for raisingand introducing the same. The rail, however, closes or hides all from view, being broughtup closely against the post above, be! neath, and on the sides of the arrangement.

The object in view is'to make a combination for a complete spring-bottom bedstead with all its parts simple, durable, and readily put up and taken apart without Va screw-driver, 'in the briefest period of time possible, in cases of emergency caused by fire or otherwise. This object, it is confidently believed, is attained by the several devices employed. The slats are very light, only three-eighths of an inch thick, and by their simple connection Awith the hinged bearings, become disengageclby simply raising them at the centre, when the bearings give so as to withdraw themselves. Theyare replaced with equal ease through the medium of the hinged bearings, being peculiarly adapted Yfor the purpose by this arrangement,

In order to understand the application of the fasteners, we will observe that as the tongues and slats are attached in front, cast in each piece, requiring no subsequent itting up, to a semicircular body or shank, withaseries of teeth on their lower half-round portion, while they are flat on. their upper surface, as shown, say one and one half inch wide, a. hole of that diameter is bored a proper depth into the ends of each These holes are bedded beneath with a composition of glue and sawdust, and the shanks inserted into their respective places.

teeth to penetrate the wood with which, and the glue and sawdust-bedding, they will become firmly lodged and permanently affixed. A three-quarter inch hole is also made, of the proper depth, in the post, above U, (Asor roXBonoUeH, MAssA- y A half-round wooden'plug, saturated with glue or not, is driven over each so as to cause their` gationsare, however,

the plate K, and squared `out vby a few strokes of a chisel, -for theadmission of the projecting portion of the-,piece or plate H, may be'reached by L on H, the tongue 1 bracing and tit-ting into the opened bevelled slots o in K, making a firinvlock, yet easily disengaged by simply lifting the rail. To guard against being' displaced when merely desiring to lift the' bedstead by the rail, to move it, the lower outer portion of the tongue L, and lower inner sides of the bevelled open. slots o, of `.the several plates, H K, are corrugated. These corrumade operative by means of the cross-bars 13g-made' so as to slightly wedge the rails, as before intimated to be explained, vthereby forcing the corrugations to interlace and thereby preventing-th fr disengagement, Without iirst withdrawing the cross-bars, thus constituting an intimate rela tion between the spring-bottom arrangement and bedl `v stead fasteners.

- We are aware-that numerous devices are employed Vfor fastening bedsteads with hooks, slots, tongues, &c.,

but we are not aware of any being constructed substantially as and applied in the manner herein speciied. We' are also aware'th'at hooks and boxes are employed for the cross-bars, screwed against the inside of the rails; such is not claimed. We are also aware in order that .the slot Nv in K that coiled springs, slats, loops, andbearings are not new, but we arenot aware that any or either vof those are arranged fand applied in the manner as herein described.
