HARRIS KARP, OF NORWALK, OHIO.

BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 517,280, dated March 27, 1894.

i Application iiled November 21, 1892. Serial No. 452,722. (No model.)

T0 @ZZ whom it may concern.-

Be it known that I, HARRIS KAR?, of Norwalk, in the countylof Huron and State of Ohio, have invented certain new and useful Improvements in Bedsteads; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improved bedstead that is extensible widthwise or laterally.

My invention consists more particularly in suitable mechanism whereby the bed-stead can be extended, as just indicated, by one operation, and my invention consists also in certain features of construction and in combination of parts hereinafter described and pointed out in the claims.

A preferable embodiment of my invention is shown in the accompanying drawings, wherein- Figures 1 and 2 are views in perspective of my improved bed-stead, Fig. 2 showing the same extended. Fig. 3 is a side elevation of the head-board looking at it from the outer side, partially broken away to show a portion of the mechanism employed in extending the bed-stead. Fig. 4 is a vertical section of the foot-board on line 4-4, Fig. 1. Fig. 5 is a top plan in horizontal section on line 5 5, Fig. l. Fig. 6 is a central vertical section of the head-board on line 6-6, Fig. l. Portions in Figs. 5 and 6 are broken away to reduce the size of the figures. Fig. 7 is a view in perspective in detail, and Fig. 8 is a transverse section on line 8 8, Fig. 7, to more clearly show the construction.

Referring to the drawings, A represents the head-board of my improved bed-stead. B the foot-board, O the side-board and B the legs of the head and foot-boards provided with casters B2. The head and foot-boards are composed of three sections 1, 2 and 3, the central section 2 being provided at each side of the central solid portion 4; of the same, with a mortise or pocket 5, to receive the end sections l and 3.

Side-boards C are secured to the respective end-sections 1 and 3 of the head and footboards in any well known manner. The endsections of the head and foot-boards, near their lower ends, are provided with a bar G (see Figs. 7 and 8) extending transversely of the end-sections and arranged in a horizontal plane, said bars being rabbeted at the top along the forward edge, as at 7, the tongue or tenon 8 thus formed at the forward edge nicely fitting a groove, 9, in a bar, 10, that eX tends in under bars 6 of end-sections l and 3, and at its rear edge is rigidly secured to the central section 2. Groove 9 extends from end to end of parts lO to enable parts 6 to slide endwise of parts lO when the end-sections of the head vand foot-boards of thebed-stead are drawn toward, or away from, each other in or out of the mortises or pockets in the central section as required in reducing or enlarging the size of the bed-stead, and bars or members 6 of the end-sections are, of course, reduced in width or cut away at the' rear edges from a point 11 near their outer ends to their inner or opposite ends to accommodate the additional thickness of the central section.

The construction just described is shown very clearly in Figs. 7 and 8. Bars 6 and lO constitute the supports for the spring mattress.

With my improved bed-stead the spring mattress would also preferably be made extensible and in addition to one stued mattress nicely fitting the bed-stead when the latter is in an unextended condition, additional sections or pieces of stued mattress would be kept on hand 1for. use when the bed-stead was extended, and such additional mattress sections could be conveniently kept, or stored away, when not in use, in a drawer provided underneath the bed-stead.

The construction of the head and foot-board sections of the bedstead is Very clearly shown in Figs. 4, 5 and 6.

The construction of the head and footboards are alike in that both are composed of sections as already described and in that the end-sections in both are adapted to slide easily in and out of the respective mortise or pocket of the central section, said pockets or mortises being sufficiently larger than the end-sections to enable the latter to slide in and out of their respective mortise or pocket without friction between the opposing sides and top-edge of the end-sections and the opposing walls of the mortise or pocket of the central section. To cause the end-sections,

ICO

however, to slide nicely Within the central section, I attach to the outer portion of the top-wall and a small portion of the side-walls of the pockets or mortises of the central section, a piece of felt, or other suitable fabric, and attach to and at or near the inner extremity of the end-sections veneer, cloth or anything, to cause the end-sections to slide nicely, and without shaking or vibrating within the central section. Such construction will readily be understood without illustration, the object being to prevent the varnish or finish of the end-sections becoming marred or scratched in drawing the same in or out of the central section, and at the same time avoid any vibration of the end-sections within the central section.

Referring now to the means and mechanism whereby the end` sections of the head and foot-boards are drawn toward and from each other, in and out of the central section, to enlarge or reduce the size of the bed-stead, I would first remark that the central section is provided, a suitable distance from its lower end, with a slat or bar 12, that extends through a slot or hole, 13, in the central solid portion of thecentralsection, being rigidlysecured to said solid portion in any suitable manner. Slat or bar 12, extends, in opposite directions into recesses or chambers 14in the end-sections. (See Figs. 3 and 8.) Slat or bar 12 extends somewhat outside of thecentral section, as at1`5,(see dotted lines Figs. 3 and 5) and thereby forms stops to limit the distance that the end-sections can be slid into the central section. Slats or bars 12 at one side, both top and bottom, are rabbeted, as at 16, for receiving horizontal rack-bars D with one of which each end-section is provided, said rack-bars being secured to the respective end-section in any suitable manner, exten ding through recess or chamber 14 in the respective end-section into the cen tral section and through hole 13 in solid portion 4 of the central-section. Chambers or recesses 14 are ,just large enough in cross-sec tion to accommodate rack-bars D and receive the rabbeted slat or bar l2 of the central-section and the rack-bars are made to nicely lit the respective rabbet, the rack-bars being reciprocated, by mechanism hereinafter described, endwise of the respective rabbet or slat or bar 12 of the central section, thereby moving the end-sections, (to which the rack-bars as already indicated are rigidly secured) out of or into the central section according to the direction in which the rack-bars are actuated.

It will be observed that the rack-bar of one end section is adapted to operate endwise of the lower rabbet in bar or slat 12 and that the rack-bar of the other end-section is adapted to operate endwise of the upper rabbet in said slat or bar.

Racks D of the end-sections of both the head and foot-boards are in mesh with spurgear E located between the racks of the pairs of racks and centrally of the solid portion 4 of the central section of said boards. Said gears are operatively mounted on a shaft e that extends from end to end of the bed-stead and has suitable bearing in the solid portion of the central section of the head and footboards, extending also through members 10 and 12 of the central section of said boards. The one end of the shaft, preferably that end that has bearing in the foot-board of the bedstead, terminates at the outer side of said board in a square portion, e', for the reception of a crank or suitable device for rotating the shaft.

By the construction hereinbefore described it will be observed that the end-sections of the head and foot-boards are slid into or out of the central section of said boards according as shaft e is turned in the one direction or the other. The head-board, however, being considerably7 larger than the foot-board, it is advisable to duplicate racks D and gear e of the operating mechanism within said board, and a preferable construction is shown in Fig. 6, that exhibits a central vertical section of the headboard and also inFig. 3, wherein portions are broken vaway vto exhibit the operating mechanism. Upon reference to these figures, it will-be observed that the end-sections of the headboard, a suitable distance above racks D, are provided with another pair of racks D and that the central section of said board is pro vided Withanother slat 12"@d at .a corresponds ing elevation and rabbeted to receive racks D', all arranged and constructed substantially as slat 12 and racksD already described. The upper pairof racks meshes with a gear, F, operatively mounted upon a spindle or shaft f, supported within the central section, di rectly above gear E, and said gears are operatively connected with each other by an endless chain G leading over sprocket-wheels g operatively mounted upon the gearsupporting shafts e and f.

17 represents slats (see dotted lines Fig. 5, and solid lines Figs. 4 and G) that hold the operating racks in place. Said slats being rigidly secured to the respective end-sections in any suitable manner, and mortises or pockets '5 of the central section are laterally enlarged for receiving said slats of the end-sections, the inclosing casing for this lateral enlargement of the mortises or pockets of the central section comprising preferably a single piece, 18, extending from end to end of the central section and perforated or recessed laterally, as at 19, to accommodate the location and operation of shaft e.

By the construction hereinbefore described, it will be observed that the operating racks are adequately supported. The rack bars at their free ends (see Fig. 3) terminate inan untoothed or plain portion d, that serves as a stop to limit the outward movement of the endsection to which the respective rack is secured.

Although I prefer the construction herein shown and described on account of its durability and efficiency, I would have itunder- VIGC IIO

stood that my invention is not in any Wise confined to said construction, but

l. In a bedstead, the combination with a head and foot board made in telescoping sections having each a bar or slat secured thereto Which extends into a recess or pocket in each of the outer sections, said slats or bars rabbeted on the upper and lower edges, and racks secured to the under sections of the head and foot boards and fitted to slide in the rabbeted edges of the Slat or bar, of a shaft extending through the bed longitudinally, and toothed gear Wheels on said shaft in position to engage the teeth of the tWo racks in the head and foot boards, substantially as set forth.

2. In a bedstead the combination with a head and foot board made in telescoping sections, having each a bar or slat secured thereto which extends into a recess or pocket in each of the outer sections, said slats or bars rabbeted on the upper and lower edges, and racks secured to the under sections of the head and foot boards, and fitted to slide in the rabbeted edges of the slat or bar, of a shaft extending longitudinally through the bed and having toothed pinions thereon adapted to mesh with the rack bars, a pair of rack-bars located above the first mentioned racks in the head of the bed, a toothed Wheel in engagement therewith, and means for communicating motion from the shaft to the last mentioned toothed pinion, substantially as set forth.

In testimony whereof I sign this specication, in the presence of two Witnesses, this 24th day of October, 1892.
