To @ZZ whom t may concern:

` Be it known that I, FnANcIs G. GALE, a subject of the King of Great Britain, and resident of Vsaterville', Province of Quebec, Dominion of Canada, have `invented anvImprovement yin CornerFastenings for Mattress Frames, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to the corner fastening for mattress frames by which the side rails andend rails of the` mattress'jframe are properly `secured together and one of `the objects of the invention is' to provide an improvedcorner fastening'which is specially adaptedjfor use in connection with tubular endmand side rails, ywhich can Vbe inexpensivelyy manufactured yand which is sui-licientlyv rig'd to ,hold ythe mattress frame from twisting. j 1 j In orderto giveI an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.

Fig. 1 is a perspective view of the corner of a mattress frame showing my improved corner fastening;

Fig. 2 is a section on the line 2-2, Fig. 1.

Fig. 3 is'a View showing a form of the invention wherein the mattress-frame is connected directly to theundeuframes of the bed and in which the side rails of the mattress frame take the place of the usual anchor iron side rails;

Fig. 4 is a view of the bed post shown in Fig. 3;

Fig. 5 is a view showing the attaching loop on the side rail.

In the drawings 1 indicates one of the side rails of a mattress frame and 2 one of the end rails to which the bed bottom fabric indicated generally at 3 is attached. rlhe j side rails and end rails herein shown are in the form of rectangular tubing, although the invention is not necessarily limited to tubular end and side rails.V The advantage of rectangular tubing for this purpose, however, is that sufficient strength can be secured with the use of a light gauge tube thereby.

providing an extremely light mattress frame. The corner fastening forming the subject of t-he present invention is one which is adaptedV to be made of cast metal, preferably malleable iron. This corner fastening is formed with a base portion 4 adapted to rest on the top of the side rail 1, two arms or legs 5 and 6 which rise from the base meniber and a rest portion 7 at the upper ends of the arms on4 whichl the end rail 2 is supported. v The device is also provided with a depending apron or flange S adapted toclose the open end of the end rail 1 and the corner fastening? further has a curb 9 rising from the rest y7 and situated to' close 'the end of the end raill 2,.

The corner fastening may be secured" to the side rail 1 by any ysuitable means. I have herein shown for this purpose bolts 10 which extend through the base' 4' and through the Vside rall. The end r'ail is secured to therest byv means of a bol-t 11 which extends through the l end rail and through a slot 12 formed in the rest 7 The purpose of the slot* 12 is"V to provide foradjustment of the end rail to plac'e the wire fabric 3 under proper tension. This adjustment is effected by means of an adjusting bolt 13 which extends transversely through the, end rail 1 near the end and through a curb 14 rising from the rest 7.

In practice I propose to so construct the curbs 9 and 14 that they will join each other thus making the right angular curb.

The adjusting bolt 13 has a head 15 of a size to engage lthe rest 7 so that the bolt will be locked from turning movement by the engagement of said head with the rest. The bolt is provided with an adjusting nut 16 on the outside of the curb 14 and a proper adjustment of the fabric 3 can be effected by simply manipulating the nut 16. The engagement of the head 15 with the rest 3 prevents the bolt from turning during such adjusting operation.

It will be understood, of course, that when. the end rail is to be adjusted the nut 17 on the hold-down bolt 10 is loosened, said bolt being tightened again after the end rail is properly adjusted.

The form of .corner fastening herein shown can readily be made of cast metal and because of its skeleton structure it is comparatively light in weight. Furthermore it is so designed that notwithstanding the skeleton structure it is sufficiently rigid to hold the mattress frame from twisting or warping. 1

tend the full width of the base and are,v

therefore, very rigid. The apron'S andcurb 9close tightly the ends of the tubular side and end rails, thus ,making it impossible for dirt to gather within Vthe tubular elements.

The structure is strengthened and made additionally rigid by reason ofthe fact that the curbs 9and 14 meet and thus constitute an integral structure.

`In some bed structures the head and foot frames are connected together by side rails and the mattress frame rests on the side rails. Y y

In Figs. 3, 4 and 5 I have illustrated a construction wherein the mattress frame is arranged to be connected directly to the head and foot frames of the bed thus obviating the necessity ofthe side rails. The bed posts 18 are each provided with a supporting flange 19, said flanges being, formed with two vertical slots 20 to form an upstanding linger 2l between the slots.4 The side rail l has a loop member 22,l secured theretol by some suitable means, either riveting or welding and the loop member is arranged to receive the finger 21, the sides of i the loop fitting intothe slots 2O as sho-wn in is not necessary.

I claim.

A mattress frame comprising one piece tubular side rails and end rails which are rectangular in cross section, a cornerfastening connecting the side rail and end rail at Aeach corner, said corner `fastening having a i base portion to rest on the top of the side rail which base portion` is of substantially the same transverse dimension as the side` flange engaging and closing the open endk ofv the end rail, said rest being slotted, a holddo-wn bolt extending through the end rail and slot of the rest and an adjusting bolt extending horizontally through the end rail and through the upward extension of the leg, the engagement of Vthe end of the end depending apron servingv to stillen themat.` y

tress frame and prevent it from twistin In testimony whereof, I have ysigne my name t0 this specification.
