MEANS FOR RETAINING MATTRESSES Application filed September 6, 1928. Serial No. 304,364.

The device, the subject of this invention, is a means for retaining a mattress in position, and the object of the invention is to make a simple detachable and attachable device that may be placed in position or removed at will, and that will not require the skill of a mechanic in placing or removing the device.

Another object of the invention is to produce a device that may be attached to the springs of an ordinary bed, and particularly a hospital bed, and that suggests the primary object of my invention.

It is well known that in the treatment of certain diseases, and in the treatment of patients of operations of various characters, that it is desirable to elevate a portion of the body, or flex the body and retain it flexed. That is, in some instances the head and shoulders are elevated, and in another instance, the feet are elevated, or the knees are flexed.

At the present time, the elevating of the head and shoulders, or knees and feet is accomplished by means of a bed, the spring support of which is formed of several parts hinged. together. On such a bed, it is particularly diflicult to retain the mattress in position. If the head portion of the bed is elevated, the mattress will slide down, and will shortly become exceedingly uncomfortable. It is sometimes dificult, if not impossible, for a nurse to replace the mattress with the patient on it, and it is well known that it is sometimes exceedingly undesirable, if not fatal, to remove the patient or the bed. The object of my invention is to prevent the mattress sliding out of place, and while I am well aware that mattress ties and metallic clamps or straps, which go across the mattress, have been employed, my experience teaches me that these devices are not only unsatisfactory, but in many instances impractical.

To overcome the objections above set forth, I have designed a device which will now be described. and reference should he had to the accompanying drawing for a complete understanding of the specification which follows.

In the drawing Fig. 1, is a perspective view of my device.

Fig. 2, a side elevation of a modified form, and

Fig. 3, a front elevation of either form.

Similar reference numerals indicate like parts in all the figures where they appear.

The main portion of my device may be formed of one piece of material, and I prefer that the material should be brass, or any other suitably strong metal. I provide a plate, and shear the plate to produce a plurality of inwardly projecting arms, as shown at 1 and Each of these arms is provided with a loop, shown at 3 and 4, and an inwardly projecting portion as shown at 5, the innermost end of which is bent outward, as shown at It will be noted that the arms 1 and 2 are produced at approximately mid length of my metallic plate. A. portion 7 projects upwardly above the arms 1 and 2, and another portion 8 projects downwardly below the arms 1 and 2.

The downwardly projecting portion 8 is in tended to rest against the outer surface of the spring bar or angle iron 9.

In placing my device in position, the hooked arms 1 and 2 are engaged over the edge of the angle iron 9, which supports the springs of the bed. The downwardly extending portion 8, of my device is then caused to abut the outer surface of the angle iron 9, and the inwardly projecting portions 5 are then caused to engage upon the under surface of the horizontal portion of the angle iron.

The mattress will restagainstthe inner surface of the upwardly extending portion, as indicated in Fig. l, and any downward movement of the mattress will cause my device to more firmly engage with its supporting angle iron. To move it, it is only necessary to raise the mattress and tip the device forward so that the loops 3 and at may be disengaged from the angle iron.

In the device shown in Fig. 1, the weight of the mattress upon the loops 3 and 4 will cause the device to be retained more firmly in position, but in the construction shown in Fig. 2, I show a bowed portion 10, which serves the same purpose and which receives the weight of the mattress to hold the device more firmly in position.

It will of course be understood that the material should have a certain degree of resiliency so that it may be engaged upon angle irons of different thicknesses, and so that it will retain itself engaged with no great freedom between the hooked member and the angle iron. This will prevent the device rattling when the bed is moved, and will make it possible to allow the device to remain in position when the bed is undergoing adjustment.

TWo or more of these devices may be used on each spring. The number will be determined by the desire of the user.

It will of course be understood that the size of my device may be changed at will, and that modifications may be made, if such are found necessary, within the scope of the appended claims without departing from the principle or sacrificing the advantages of this invention.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is 1. A mattress retainer for detachable adv justable mounting on the angle iron of a bed frame, said retainer comprising an upright plate having horizontally projecting arms at the opposite edges of the same to extend inwardly over the flat top of the angle iron to thereby support the plate on top of the angle iron, said plate having a downwardly extending projection between the horizontally projecting edge arms engageable with the outer face of the angle iron to limit inward movement of the plate over the angle iron and said horizontally extending arms terminating at their inner ends in downturned hook portions engageable over the inner edge of the top portion of the angle iron to grip the plate portion of the retainer in the position to which it is fixed by the dependent intermediate portion of the same.

2. A mattress retainer for mounting on the angle iron of a bed frame, said retainer comprising a horizontal arm engageable over the flat top of a bed frame angle iron and terminating in a down-turned hook engageable over the inner edge of the top flat portion of the angle iron, an upstanding plate at the outer end of said horizontal arm to engage and retain a mattress reSting on the angle iron and an upright portion dependent below the plate to engage the outer face of the angle iron to thereby prevent inward displacement of the plate over the top of the angle iron and to hold the hooked portion of the horizontal arm engaged over the edge of the said top of the angle-iron in the normal position of use.

3. As a new article of manufacture, a mattress retainer comprising a flat plate having opposite edge portions partially severed therefrom and bent substantially at right angles to the plane of the plate, with that portion of the plate between said partially sev- LUCILLE TULL ROBINSON.
