s'IDE RAIL LOCK Filed June 2, 1923 uliiiiii Patented ug. 12, y 1930 FRANK KUSTERLE, OF XENOSHA, WISCONSIN, ASSIGNOR T SIMMONS COMPANY, OF

KENOSHA, WISCONSIN, A CORPORATION OF DELAWARE SIDE-.RAIL LOCK Application led June 2,

My invention relates to fastening devices for detachably securing the side rails of a bed to the bed ends.

The principal objects of my invention are to provide a connection of so simple a forml that it may be readily assembled and taken apart by inexperienced persons; to avoid the necessity of using tools oi wrenches in connecting or disconnecting the rails and bed ends; to dispense with loose parts; to insure a permanent rigid connection; to construct the parts of rolled or stamped metal and thereby eliminate possibility of breakage; to reduce the numberof parts to a minimum; to utilize the end of the side rail as a bearing face for holding the bed end in upright position; and to provide a neat and compact corner fastening which may be readily a'pplied to various types of corner posts.

Referring to the drawings:

Fig. 1 is a side view of a corner connection embodying my improvements;

Fig. 2 a sectional View thereof, taken substantlally on the line 2-2 of Fig. l;

Fig. 3 a top view of the corner connection showing the construction of the remote end of the side rail;

Fig. 4 an enlarged detail view of the bracket seat for confining the end of the up- 30 right flange of the side rail; and

Fig. 5 a view similar to Fig. 2, showing the side rail in reverse position.

On the drawings, the reference numeral 1 indicates a fragmentary portion of a tubularA bed post, 2 a side rail of theV bed and 3 a bracket for securing the side rail to the bed post. This bracket 3 comprises an upright elongated plate portion 4, the outer face of which is formed to' correspond to the form of the post to which it is to be attached,vin the present case the outer face of the plate 4 being concave to t the circular post 1. This plate is clamped onto the post by cap screws 5, or rivets if desired, which are passed through apertures near the upper and lower ends of the plate 4 and through corresponding apertures in the wall o f the post 1 and are secured to a washer G inside the post, sov as to clamp the wall of the post between the late 50 4 and washer 6 At the outer edge o the 1923. Serial No. 643,075.

plate 4 the bracket 3 is formed with a wing 7 having a vertically elongated notch 8 formed therein which is open at the top, the forward edge of said notch being arranged at a slight angle to the plane of the plate 4 as shown in Fig. l, so as to afford a wedge action as hereinafter described, for clamping the end of the side rail against the plate 4. The bracket 3 is preferably of pressed or rolled metal and the notch 8 is formed therein by stamping or punching the section of metal within the notch outwardly from the side wing 7 in such a manner that the front'bearing edge shears orf on a slight bevel as shown at 9.

The side rail 2 is in the form of an angle iron and has a headed stud 10 secured to the upright Hange thereof a short distance from each end. This stud is arranged substantially midway between the upper and lower edges of the side fiange of the angle iron and is preferably somewhat tapered as shown particularly in Fig. 3, to insure a tight fit in the aperture of the rail flange and also to cooperate with the bevel edge 9 of the notch 8 so as to afford a lateral drawing of the upright flange of the rail against the side wing 7 of the bracket, and the inner end of this stud is u set or riveted over against a washer 11 which is placed against the inner face of the upright flange `of the angle iron side rail.

` It is desirable in bed constructions to have the angle iron side rails arranged so that they may be reversed, that'is, so that they may be positioned with the horizontal Hange at the top as shown in Fig. 2, or with the horizontal flange at the bottom as shown in Fig. 5. In the present construction the end of the angle iron butts against the plate portion 4 of the bracket 3, and in order that the horizontal lange may clear theupper cap screw or rivet 5, the ends of the angle iron are notched as at 12, said notch being extended so that the inner side thereof is substantially flush with the inner surface ofthe upright iiange of the angle iron, and forms a tongue 13 at each end of the angle iron consisting of the end portion of the upright flange of the angle iron and also a narrow tongue 14 at each end A consisting of. an end portion of .the horiture of the side wing bracket 3 is formed with an upwardly exzontal flange of the angle iialiln.h Atlthe junlwit t e p ate 4 t e tending flaring groove, channel or recess f15 of a form substantially as shown in Fig. 4, which is engaged bv the tongue or projecting end 13 of the'upriglit flange of the angle iron when the stud 10 isl engage in the wedging notch 8, said channel or rece s 15 being adapted to confine the end ofthe tongue 13 and hold s ame rigidly against lateral displacement. The engagement of the tapered portion of the stud 10 with the'beveled edge 9 of the notch 8\ serves at the same time to. increase the rigidity of the connection by drawing the side flange of the angle iron laterally against the side wing 7 of the bracket 3, such lateral i drawing action` being also supplemented by the engagement of the projection 'or tongue 14 of the horizontal flange of the angle iron 'against the plate portion 4 of the bracket, as thetongue or projection 13 of the upright flange is inserted into the seat 15.

It will' be observed that because the pin or stud projects laterally .from the plane of the vertical flange of the side rail, the'thrusts or reactions of the bracket parts against the end 13 of the flange and against the shank of the pin 10, are substantially out of line or oiset so as to provide a twisting couple or moment between the bracket and the rail which also tends to draw the free endV of the wing 7 and the vertical flange of the. side rail in to intimate contact. There is no tendency forthe end 13 ofthe side rail to slip on the plate part 4 of tbe bracket for the reason that the end 13 of the side rail is rigidly wedged or anchored in the groove l5.

e t is customary -to connect the two posts of each bed end by means of a cross rail which is usually located at Y' about the same elevation as the side rail of the bed, and in my present construction th'is cross rail, which vis indicated at 16, is arranged somewhat below the lowest position of the side rail 2, so as to afford ample clearance, and has ythe ends connectedl to the post 1 by means of the lowermost cap screw or rivet 5 which serves to secure the bracket 3 to the post. The side wings 7 of the bracket 3 are positioned at the outer side of the therefore concea the ends of the cross brace Y 16 and the parts which connect the brackets 4 side rail interl to the post 1, and the corner fastening therefore resents a. neat compact appearance.

With this construction, it will be observed A late 4, and these side wings z fan open top notch, an angle iron side rail havingan upright flange and a horizontal flange, a lateral projecting stud on said upright flange wedgingly engaging the notch of the wing 4member so as to jam the end edge of said flange nto'the aforesaid seat, said notch being provided with'a beveled bearing edge and the stud with a ta ered stem forjengagement with the beveled e ge whereby the upright flange ofthe angle iron is wed edagainst the wing member of the brac et.

2. 'In a bedstead corner fastening, the combination of a corner post having a bracket attached thereto, a portion of said bracket 'projecting therefrom, said projecting portion having. an open-ended slot therein formed'with an edge inclined toward the post at its lower end, said edge being beveled, and a side i'ail having a laterally projecting stud having a ta red shoulder adapted to engage said bevele edge of said slot .whereby clamping en agement is effected between the side of sai rail and said bracket and also between the end of said rail and another portioii of said'bracket.

3. In a bedstead corner fastening, the coinbination of'a corner post, a bracket having a vertically .extending plate secured to the post and a vertically extending win projecting outwardly from one side of'sai plate, and having an inclined slot formed therein, a side rail having an end part disposed against the inside of the wing and havin its extremity engaged in the angle of the racket, and a in secured to said end part and projecting aterally into. said slot to wedge said end part against the plate, the inter-engagin parts o the .pin and slot being relatively veled so as to draw the end part into intimate contact with the wing.
