METAL BEDSTEAD.
tion is to provide new and improved means for connecting the members of a bedstead, particularly the members forming the head and foot of a bedstead, without the use of the usual exposed studs and nuts, and which will be entirely inclosed when said members are connected, thus providing against accidental loosening or disengagement of the connecting means and thereby insuring a rigid structure at all times. Moreover, a
bedstead embodying my invent-ion, though very plain, will present a very neat and attractive appearance.
A bedstead of my invention comprises the various features and details of construction hereinafter described and claimed.
In the accompanying drawing, in which my invention is fully illustrated Figure l is a partial. end view of a head or foot of a bedstead embodying my invention. Fig. 2
80 is an enlarged fragmentary sectional view on the line 2)-2 of Fig. l. Fig. 8 is a top plan view of the parts shown in Fig. 2, the transverse tubular member being broken away in part. Fig. 4 is a sectional view on the line 4 4: of Fig. 2, showing the locking means in engagement. Fig. 5 is a view substantially similar to Fig. i, showing the locking means disengaged. Fig. 6 is a view similar to Fig. t, showing a modified form 7 is a sectional view on the line 7 7 of Fig. 6; and Fig. 8 is a view substantially similar to Figs. 2 and 7, showing a modification.
Referring now particularly to Figs. l to 5 0f the drawings, A designates, as a whole,
part of an end of a metal bedstead embodying my invention, comprising posts l, only one of which is shown, top and bottom transverse frame members 2 and 3 which connect the posts of the bedstead, and upright members 4 connecting said transverse members 2 and 3. The transverse members 2 and 3 are hollow, while the members t may be either hollow or solid. The transverse members 2 and 3 may be connected to the posts Specification of Letters Patent.

l by means similar to those hereinafter described for connecting the upright membersv 4 to the transverse member 3, or in any other desired manner. My improved connecting means, which is shown in the drawing` as applied for connecting the lower ends of the upright members4 to the lower transverse member 8, is .as follows r-Formed in said transverse member 3 are a series of holes 5 adapted to receive the lower ends of the upright members i, said upright members 4 preferably fitting said holes or openings 5 closely, so as to present a neat and finished appearance. Formed in the sides of the upright members t, adjacent to the lower ends thereof, are kerfs 6, the top sides 7 of which preferably extend at right angles to the surfaces thereof and the lower sides 8 of which are preferably inclined upwardly toward the inner ends of said kerfs. The positions of the kerfs 6 are such that, when assembled, said kerfs will be within the transverse member 3. Said connect-ing means also comprise a plate 9 adapted to be inserted lengthwise into said transverse member 3. Formed in said plate 9 are holes l0 of substantially the same size as the holes 5 formed in the member 3 and spaced corresponding distances apart, so that the holes in said plate 9 may be brought into register with the holes 5. The plate 9 having been inserted inside of the member 3 and positioned so as to bring the corresponding holes 5 and 10 into register with each other7 the lower ends of the upright members 4L are inserted through said openings 5 and 10 with the open sides of the kerfs 6 all on the same sides of said upright members 4. The plate 9 is then forced endwise in proper direction to cause the edges of said plate atv the sides of the openings l0 to engage the kerfs 6, the relation being preferably such that said plate will engage the inclined lower sides 8 of said lrerfs, whereby a wedging action will be exerted on the upright members 4f, thereby preventing rattling of the members 4: and plate 9 and also creating a friction which will operate to secure said plate in locking position. kMy invention, however, contemplates securing said plate 9 positively in locking position, as by means of a pin l1,which connects said plate with the hollow member 3, or in other desired manner. Vhere the transverse member 3 is round, the position of the lower sides of the kerfs 6 will be above the center of said transverse member, the plate 9 being preferably substantially flat and of such width that it will engage the sides of the tubular member 3 substantially in line with the lower ends of the inclined sides 8 of the kerfs 6. Thus, as said plate is forced endwise to effect engagement thereof with said kerfs, it will be slightly bent or bowed upwardly substantially as shown in Fig. 2 of the drawing. My invention, however, contemplates equally making 'said plate curved transversely so that it will conform to the inner surface of said transverse member 4, in which event the kerfs 6 will be correspondingly curved. In Fig. 8 of the drawing in which I have shown a plate and kerf of this character, 31 designates the transverse member, 41 the end of an upright member, 61 a kerf formed in the lower end of said upright member, and 91 a plate adapted to engage the kerf 61. If desired, said curved plate may be made in the form of a tube or pipe adapted to be inserted endwise into the hollow member. In said Fig. 8, this modiicat-ion is illustrated, the dotted line 92 indicating the plate 91 extended to form a Y tube.
In Figs. 6 and 7 of the drawings, I have shown a modified form of connecting means embodying my invention, which consists in utilizing two plates corresponding to the plate 9, respectively adapted for engaging kerfs formed on opposite sides of the upright members. In said Figs. 6 and 7, I have shown an application of my invention when the lower transverse member is s uare. Referring now to said Figs. 6 and 4, 32 designates the transverse member, 42 designates the upright members, the lower ends of which extend into the transverse member 32, G2 are kerfs formed in opposite sides of the upright members 42 which are adapted to be engaged by the plates 93, 91 by endwise movement of said plates in opposite directions, thus providing a double lock.
Where the plates which engage the kerfs in the upright members bear directly against the inner upper sides of the transverse members, the kerfs in said upright members will preferably be so positioned that they will terminate flush with or slightly outside of the inner surface of said transverse member. The opposite ends of the upright frame members may be connected to the other transverse frame member, in the present instance the transverse frame member 2, in the same manner as they are connected to the transverse member 3, or in any other desired or approved manner, but preferably in such manner that the connecting means will be entirely inclosed.
I claim A metal bedstead comprising a hollow first member and a plurality of second members connected to said first member, the means for connecting said seco-nd members to said first member comprising a locking plate inserted lengthwise into said first member, said first member and plate being provided with holes through which the ends of said second members are inserted and said second members being provided within said first member with kerfs formed directly in the sides thereof which are engaged by the locking plate at the sides of the holes therein, and said kei-fs comprising inclined sides which coperate with said lockingj plate to exert a wedging action on said Vsycond members, substantially as described.
In testimony, that I claim the foregoing as my invention, I aiix my signature in presence of two subscribing witnesses, this 30th day of March, A. D. 1910.
