(01. 5-262) 1 2 Bed springs commonly embody a basefra-me which supports a multiplicity of load-supporting The upper ends of such particular form of bed spring illustrated and de scribed is shown merely by way of example. The bed spring shown in the drawing embodies springs are located substantially in a common plane and are surrounded by a border frame se a stabilizer l5 in the form of a strip of flat stock connected at one end to the border frame l3 and compression springs. cured to the upper ends of the marginal springs. extending obliquely downwardly and inwardly In such a construction, it is customary to provide of the spring to a point adjacent the base frame a stabilizer which acts resiliently between the Ill-H to which it is connected, preferably border frame and. the base frame and opposes any through the lowermost turns ‘of interior springs relative horizontal displacement of such two 10 l2, by tension springs I6 and H so arranged as frames. The stabilizer usually takes the form of to tend to hold the border frame |3 directly above a bar which is secured to the border frame, ex the base frame. tends obliquely downwardly and inwardly of the At the point where the stabilizer I5 is to be spring assembly, and is connected by springs to connected to the border frame l3, the latter is the base frame. 15 provided on its inner face with a longitudinally My invention relates to such a stabilizer and extending slot 20 adapted to receive the end of more particularly to a means for securing such the stabilizer I5. In the stabilizer I5 I provide a stabilizer to the border frame. It is the object of transversely extended slot 2| positioned so that my invention to connect the stabilizer to the a portion of its width will be received within the border frame by a connection which will be ade 20 slot 20 when the stabilizer I5 is in place. To effect quately ?rm and secure and which can be sim a permanent connection of the stabilizer IS with ply and economically effected in the assembling the border frame l3, the slotted end of the sta of the spring. bilizer is placed in the slot 20 of the border frame, In carrying out my invention, I preferably form and the metal of the border frame at the edges of the border frame of round stock. At any point 25 the slot Zll is deformed by a suitable die to produce where the border frame is to be connected to a stabilizer, it is provided on its inner side with a ears 22 which enter the slot 2|, as indicated in Fig. 4. ' ' horizontally extending slot having a width sufli The slot 20 is most conveniently formed by a cient to permit it to receive the end of the sta saw or milling cutter, and its bottom wall has a bilizer bar. Near such end, the stabilizer bar is 30 radius corresponding to that of such saw or cut provided with a transversely extending slot. In ter. I prefer to form the end of the stabilizer IE connecting the stabilizer to the border frame, the to conform near its center to the curvature of the slotted end of the former is placed within the slot bottom wall of the slot 25, and I round the cor of the latter, and the metal at the edges of the ners of the stabilizer l5 as indicated at 23. With slot in the border frame is deformed to provide 35 such a construction, the stabilizer can be moved lugs extending into the slot of the stabilizer and longitudinally of the border frame for a limited preventing the removal of the stabilizer from the extent while the slot 2| is still left in position to border frame. _ receive the deformed metal constituting the ears The accompanying drawing illustrates my in 22. Desirably, the ears ‘22 bear against the ends vention: Fig. 1 is a fragmental plan view of a bed 40 of the slot 2| and also against the outer edge spring; Fig. 2 is a fragmental vertical section on thereof. The former bearing prevents movement the line :2-2 of Fig. 1; Fig. 3 is a fragmental of the stabilizer l5 longitudinally of the slot 20, plan view on an enlarged scale and with a por while the latter holds the end of the stabilizer l5 tion of theborder frame broken away; and Fig. ?rmly against the curved bottom wall of the slot 4 is a fragmental vertical section on the line 45 20. This firm connection of the stabilizer to the 4-4 of Fig. 3.“ border frame is desirable, as it decreases the pos sibility of noise.
