MILTON F. MADDOX, OF INDIANAPOLIS, INDIANA.

CORNER-FASTENER FOR BEDS.

SPECIFICATION forming part of Letters Patent No. 726,554, dated April 28, 1903.

Application filed January 2,1903. $erial No. 137,510. (No model.)

To all whom it may concern/.-

Be itknown that I, MILTON F. MADDOX, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Corner-Fasteners for Beds, of which the following is aspecification.

This invention relates to corner-fastenings for beds; and the object of the invention is to provide a fastening which will permit the bed-rail to be reversed-that is, placed either side up.

The object also is to provide a fastening which will insure a firm and stable vertical position of the bed-posts at right angles to the bed-rail and to provide a fastening in which all of the parts are intact with one or the other of the two parts to be joinedthat is, a faslening in which there are no loose screws, bolts, or wedges to be misplaced or lost.

The object, further, is to provide a simple, durable, and inexpensive fastening device.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a detail in elevation of a bedpost and bed-rail provided with my improved corner-fastening, the post being shown at only one end of the rail; Fig. 2, a top plan view of same; Fig. 3, a horizontal section on the line-3 3 of Fig. 1; Fig. 1, a vertical section on the lines 4 4 of Figs. 1 and 2; Fig. 5, a section on the line 5 5 of Fig. 2.

Like characters of reference indicate like parts throughout the several views of the drawings.

6 represents part of the metallic post of a bedstead, and 7 a sleeve cast and shrunk upon the post. The sleeve has the vertical shank 8, which has an abrupt decrease in thickness on one side, preferably that toward the outside of the bed, to form the shoulder 9. The thinned portion of the shank has the perforation 10, with an extension 11 of less width taking from the lower side of the perforation and extending downwardly from said perforation, as shown in Fig. 5. The outer wall of this extension 11 slopes inwardly at its bottom for reasons which will be hereinafter explained, and the opposite wall may stand parallel with the post 6, but will have an outward taper 11, as shown in Fig. 3, to

enable the mold to be withdrawn freely after the casting is made. The inner face 12 (see Fig. 4) of said shank has an upward taper starting from below the slot 11.

The side rail 13 of the bed-frame is preferably of angle iron or steel and has the cast iron or steel head 14 terminating each ofits ends. These heads are reduced in thickness from their inner sides to form shanks 15, the counterparts of shanks 8 of the post. The reduction in thickness is abrupt to form the shoulder 16; but preferably the shank 15 is longer than shank 8, in order that a close fit of the end of shank 15 may be had against shoulder 9.

17 is a stud-pin which is inserted in the mold in which the head of the rail is formed before said head is cast, and the pin is socurely held by the metal of the head, which is poured around it in casting the head in the same manner as the head is cast upon the rail. This pin is positioned so as to register with the perforation 10 when the two shanks are brought together. The pin has a head which barely passes through said perforation and a body narrowed on each side, so as to be capable of insertion in the slot 11. The said stem onits side adjacent to theouterorsloping wall of slot 11 is likewise sloping, so that when the pin is forced down in said slot the shank 15 will be forced against the shoulder S). This will hold the bed-posts firmly in avertical position. The inner faces of the head being those which contact with the shank 8 are beveled from a mid-line upwardly and downwardly, as shown at 17 in Fig. 4, to match the taper of the shank 8, so that the forcing of the pin in slot 11 will draw the two shanks together tightly to prevent lateral movement of the bed head or foot. The double bevel of the face is to provide for a fit when the rail is reversed or turned the other side up. As the metal of the head in casting may not knit firmly to the material of the stud-pin, I insure its solid anchorage by providing the lateral ribs 18, which give sure engagement to the metal of the head. To reverse the bed-rail, it is only necessary to turn the rail end for end. The corner 19 will preferably be rounded, as shown, and the contacting faces leading both ways therefrom will be planes parallel with the post.

While I have only shown one slot and one stud-pin at each fastening, it is obvious that two or more might be used without departing from the spirit of this invention,'and I therefore do not limit my invention to the number shown.

Having thus fully described my invention, what I claim as new, and wish to secure by Letters Patent, is

1. In a corner-fastener for bedsteads, a post, a shank on the post having an abrupt decrease in thickness on one side to form a shoulder, said shank also having a perforation, a rail or frame fixture having a head with a thinned end to fit against the shoulder and reduced side of the post-shank, said rail end having a stud-pin which passes through the perforation of the shank, said perforation having a reduced portion and said pin having a body portion adapted to enter the reduced slot and shoulders at each side of said body forming a head to engage the shank on each side of said slot.

2. In a corner-fastener for bedsteads, a post, a shank on the post having a shoulder and a downwardly-tapering slot in a downwardlythickening portion of the shank, a rail or frame fixture having a head complementary in shape to said shoulder and shank, said head having a stud-pin which passes through the perforation of the shank and draws the parts of the joint together in two directions when forced to the bottom of the tapering slot.

3. In a corner-fastener for bedsteads, a post, a shank on the post having a shoulder formed by an abrupt thinning of the shank, said thinned portion having a downwardly-taperingslot, and said thinned portion of the shank having a tapering outer face which increases the shank in thickness downwardly to below the slot, a rail or frame fixture having a head with a reduced end to fit and fill the reduced portion of the shank said reduced end having a stud-pin with lateral enlargements forming a head, said pin registering with and passing through the perforation of the shank when the parts of the fastener are united, the action of the pin on the tapering slot and thickened shank being to draw the parts together when the pin is forced down into the slot.

4. In a corner-fastener for bedsteads, a post, a shank on the post having a shoulder, said shank having an upward taper and having a perforation with a narrower extension from the bottom of said perforation, the outer wall of said extension sloping downwardly toward the post, a bed-rail having a head with a studpin projecting therefrom adapted to pass through the perforation of the shank when the parts of the corner-fastener are assembled said pin having an expanded end forming a head and a narrower stem adapted to enter the extension from said perforation.

5. In a corner-fastener for bedstead s, apost, a shank on the post having a shoulder, said shank having an upward taper and a perforation with a narrower extension from its bottom, the outer wall of said extension sloping downwardly toward the post, a bed-rail having a head with a stud-pin projecting therefrom adapted to pass through the perforation of the shank, said pin having an expanded end forming ahead, the inner surfaces to contact with the shank being beveled, the stem of'the stud-pin being narrower than the extension from perforation of the shank and said stem having a sloping side to contact with the oblique slot of the shank.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 23d day of December, A. D. 1902.
