JOHN BURNS, OF KENOSHA., WISCONSIN, ASSIGNOR TO THE SIMMONS MANUFACTURING COMPANY, OF KENOSI-IA, WISCONSIN', A CORPORATION OF WISCONSIN.
METAL JOINT.
Specification of Letters Patent. Patented June 19, 191 '7.
Application led .Tune 14, 1913. Serial No. 773,613.
customary to secure the corner-joint-casting,I or, as 1t is known to the trade, the frenching' which supports the side rail, or the side rail itself, to the upright hollow post by molding the frenching or side rail to such post. In pouring' the molten metal, a mold is provided in the upright for confining the molten metal around the joint. The l'present 'invention relates more specifically to improvements in the manner of securing themold plate in position in the upright.
The salient object of the present invention consists in confining the mold plate in position within the hollow upright by means of a resilient locking member interposed between the rear face of the mold plate and the opposed wall of the upright or other tubular member in which the mold plate is inserted. Subsidiary objects of the invention are to provide a simple and economical construction whereby the mold plate may be readily secured in position, and without the aid of screws or bolts, o1` the like.
The invention consists in thematters bereinat'ter described, and more particularly pointed out in the appended claims.
In the drawings,-
Figure l is a vertical sectional view showing the manner of securing a frenching to a tubular, upright bed-post by means of the present invention;
Fig. 2 is a horizontal sectional view taken on the indirect line 2 2 of Fig. l and looking in the direction of the arrows; and
Fig. 3 is a view similar to Fig. l, but showning the manner of securing a cross rod of a beddirectly to the upright.
Referring tothe drawings,*l designates a hollow, tubular post or upright, 2 the frenching or corner-'fastening member, all of well known construction. The side wall of the upright l opposite the renching or The moldplate, as shown clearly in the drawings,` is bent to iit snugly against the inner wall of the uprightand over the aperture 3 thereof. This mold plate 4 is held in position by means of as'pring-supporting member 5. This spring-supporting member comprises a body portion 6 which abuts against the wall of the upright l, and a pair of inwardly curved side arms 7, 7, the ends 8 of which extend through suitable apertures 9 in the mold plate'. The arrangement 70 just described is such that the spring-supporting' member 5 holds' the mold plate 4 Jnightly against the inner' wall ot the upright s o as to form a cavity into vwhich the filling or internal locking-head or clenchilO may be poured. In practice, theY frenching 2 and .the internal clench 10 are bothformed by a single pour of the molten metal. The manner in which this joint is formed is apparent, but may be briefly described as follows:
'Fhe mold plate, with the ends ofthe spring support 5 extending through the apertures 9, is inserted in one end of the tubular upright, and then forced through the tube until the mold plate is opposite the aperture 3. By reason ofthis sprinv support, no extraneous fastening devices of any kind are necessary for securing the mold plate. The latter is merely pushed through the tube until it is centered over the aperture 3. In order to prevent the ends 8 of the springs from projecting too far through the mold plate or the latter working loose on the springs, I provide the arms 7 with shoul- 95 ders l1, as shown clearly in the drawing.
In constructions of this character, not only the cost of the parts forming the joint,
ybut also the labor and time expended in locking the parts together is an important feature from a commercial standpoint. lThe present invention effects a substantial saving in these respects. v
In Fig. 3, I have shown a somewhat modified construction, in which a cross rod 2 105 is connected directly to the upright l, instead of by a frenching. In this construction the upright is providedwith the same Vaperture 3, through which the end of the side rail 2 projects.- In order that the in- 110 tcrnal clench l0 may be poured into the cavity formed by the mold plate, the side wall of the upright is provided with two small apertures 3, through which the molten metal may be poured. In this construction the ends 8 of the spring support project slightly into the end of the side rail 2 in order to obtain a somewhat stronger joint. The molten metal which forms the internal clench 10 not only iills the cavity formed by the mold plate, but also extends some little distance into the said rail 2. Otherwise the construction is the same as that heretofore described.
In its broader aspects, the invention is not limited to the details of construction shown except as set forth in the appended claims.
I claim as my invention:
l. The combination with a hollow post having an aperture in its side, of a mold cup in the post fitting over said aperture, a spring having its ends projecting through the openings in the rear of the mold cup and having its intermediate portion abuttino against the opposite wall of the post, and a filling cast through said aperture into the cavity formed by the cup.
2. The combination of a hollow post with a perforation in its side, a mold plate fitting within said post and having an inwardly depressed portion forming a cavity registering with said perforation, said depressed portion having a pair of apertures spaced apart in a direction parallel with the axis of the post, a resilient wire member having its ends entering said apertures and with its intermediate portion engaging the Wall of said post opposite said perforation for resiliently maintaining said plate in position, and a metal filling east through said perforation in the cavity formed by said plate.
3. The combination of a hollow post with a perforation in its side7 a mold plate fitting within said post and having an inwardly depressed portion forming a cavity registering with said perforation, said depressed portion having a pair of apertures spaced apart in a direction parallel with the axis of the post, a. C-shaped resilient wire member having .its ends reversely bent to enter said aperture and with its intermediate portion engaging the wall of said post opposite said perforation for resiliently maintaining said plate in position, and a metal filling cast through said perforation in the cavity formed by said plate.
