BEDSTEAD.

Application filed August 31,

Specification of Letters Patent.

Patented Sept. 21, 1999.

1968. Serial No. 450,938.

To all whom it may concern:

Be it known that I, Josnrn ARTHUR Gunmen, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented a new and useful Bedstead, of which the following is a specification.

My invention relates to improvements in bedsteads having two sides attached to two ends and cross bars between the sides to support the bed; and the objects of my improvement are, first, to make the ends extensible so as to convert the bedstead from double to single or single to double as may be desired; second to make the operation of extending l the bed quick and simple; third to make the bed appear as one not extensible; and fourth, to make an extensible bedstead to which the elegance and richness of design sought in fine homes can be applied. I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is an elevation of the bedstead end extended for double bed; Fig. 2 is an elevation of the bedstead end reduced for single bed; Fig. 3 is a horizontal section on the line A. A. of Fig. 1, the lines a? and y are center lines, and all parts in this figure are symmetrical about these lines; Fig. 4 is a vertical section on the line D. D. of Fig. 3, the line a is center line about which the parts are symmetrical; Fig. 5 is a vertical section on the line E. E. of Fig. 3, the line to is center line about which the parts are symmetrical; Fig. 6 is a vertical section through the middle-joint in the plane of line B. B. of Fig. 3; Fig. 7 is a vertical section through the cross-head in the plane of line F. F. of Fig. 2; Fig. 8 is a horizontal section on the line H H of Fig. 7; Fig. 9 is a vertical section through the corner-joint in the plane of line B. B. of Fig. 3; and Fig. 10 is a vertical section in the plane of line B B of Fig. 3, showing one of the pins of the operating panel.

Similar letters refer to similar parts throughout the several views.

The several parts are made of brass or other material befitting the purpose, and of suitable forms, sizes and designs.

The main posts K, which are provided in the usual manner with casters P, the posts L and M and the bars N, with the elbows e at the corners adjoining the extensible portion, constitute the lateral rigid portions of the bedstead ends; these parts are screwed one to another or otherwise secured to each other in any suitable manner. The extensible portion of each end is formed of the parts described as follows: The elbow e of the corner-joint is tapped on two sides and the post M and the bar N are connected thereto, it has a cavity a in which the eyepiece Z is held by a pin f passing through the elbow e, the cavity a is made so as to al low only the required movement of the eyepiece L in the action of extending or reducmg the bedstead, the upper and lower sides of sald cavity a acting as a stop for said eyepiece Z.

The tee a of the middle-joint has two cavities t in which the eye-pieces Z are held by p ns f passing through the tee a, the cavities t are made so as to allow only the requlred movement of the eye-pieces Z in the action of extending or reducing the bedstead,t'he upper and lower sides of said cavitles Z acting as a stop for said eyepiece Z. The swing-arms are formed of a bar in having an eye-piece Z screwed on or otherwise fastened to each end, the eyepiece Z is made to fit in thickness the cavity a or t, and has a hole bored through to receive the pin f, one end of the arms is connected to the tee a, and the other end is connected to the elbow e. The rods 0 and a? are screwed in, or otherwise suitably fastened to the tee a, the rods 0 and d have on one side, the bosses g and h, and the rod G has, at its lower end, the knob z in which there is a suitable cavity to receive and conceal the upper end of the rod 03 when the bedstead is extended. The operating panel is formed of two cross-heads b and two standards 0; the sleeve 7) of the crosshead I) is bored vertically to allow the passage of the rod 0 or (Z, one side has a cavity at in which the boss h or g engages, the other side has a groove 12 to allow the passage of the bosses g and h. The bar 9 of the crosshead I) has, at each end, a hole to allow the passage of the pin a. The standards 0 are tapped at the top and bottom, and the pins r are screwed therein so that the standards 0 can be revolved on the axis corresponding to the center line of the pins r; or be held firm by the said pins r screwed in tightly, making them folding standards. Two ends, as described above, with two sides and other parts described hereafter complete the bedstead as it needs be for the intended purpose.

The sides T, the cross-section of which is L shape, having hitch holes f in their horizontal leg, are connected to the lug Z of the main post K by a tongue and groove connection 9 The bars G of the end supports are made of square or round material cast with or otherwise suitably fastened to the said'lugs z, a hole is tapped on one side of the bar Gr to receive the thumb-screw (Z thebar Q, is made of hollow material or tubing of such size and form that the bar G made of square or round material of' such size as will allow them to slide closely but freely in the bar R, the outward end of the bars I is made to rest on the horizontal leg of the sides T and has a hitch pin or projection e passing through the hitch hole in said horizontal leg. There will be two or more intermediate supports to suit the requirement.

To reduce the bedstead from double to 'single, loosen the thumb screws d and the pins 1' by slightly unscrewing them, turn the standards 0 so that their point S will be toward each other, as shown in Fig. 2, screw the pins in tight, turn the operating panel 180 degrees, when the boss 9 will be out of the cavity at and be in line of the groove n, draw the tees ct, farther apart one from the other until the boss it comes opposite the cavity m, turn the operating panel back to i its former position when the boss it will engage into the cavity m and lock the n1echa11- ism, then screw the thumb-screws (Z1 in tlght;

in this operation, the lateral rigid portions l of the bedstead ends and the sides T will be I drawn closer one toward another, the thumb screws (Z and the pins 0 will slide to the i11- ward end of the slots and a respectively.

I am aware that, prior to my invention, bedsteads, having sides connected to the ends by tongue and groove, and cross bars to support the bed, have been made, I am also aware that patents have been granted for extension be'dsteads of the telescopic kind. I therefore do not claim such combinations broadly; but

I claim: 7

1. In a bedstead the combination with the two lateral rigid portions of the bedstead end having corner-joint elbows of the swingarins having at each end an eye-piece, the middle-joint tees having each a vertical rod provided with bosses, and the operating panel working in conjunction with said vertical rods; the swing arms being connected in pairs by pins passing through the tees, and one end of each pair being connected by a pin to said elbows forming a flexible connection between the said lateral rigid portions whereby the said lateral portions are drawn closer together or forced farther apart, all substantially as and for the purpose set forth.

2. In a bedstead, the combination with the lateral rigid portions of the bedstead end having corner-joint elbows, the swing arms and middle-joint tees having each a vertical rod provided with bosses, of the cross-heads bored vertically and having a groove and a cavity for guiding said vertical rod and lodging said bosses whereby locking the combination, and the folding standards connected by pins to the cross-heads, substantially as shown and for the purpose described.
