SPRING-MATTRESS.

Specification of Letters latent.

Patented Sept. 23, 1913.

Application filed November 16, 1911. Serial No. 660,728.

To all whom it may concern:

Be it known that 1, JOHN L. TANDY, a

citizen of the United States, residing at L Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Spring-Mattresses, of which the following, is a specification.

This invention relates to spring mattresses and its main object is to produce a light, rigid and cheap frame of such construction that its weight will be imposed upon the side bars of the bed frame at such points as to hold said bars in proper relation to the head and foot ends, if said bed frame is of that type in which the head and foot ends are provided with downwardly-tapering sockets and the side bars with downwardly-taper ing lugs to be fitted down into said sockets A further object is to produce a spring mattress provided with simple, cheap and efficient trusses for trussing the fabric for guarding against undue lateral spreador lateral movement of the ordinary mattress adapted to fit upon the fabric.

A still further object is to provide auxiliary side guards for preventing lateral movement or spreading of the said ordinary mattress, and movable vertically upon the side bars of the mattress frame and connected to the fabric: so as to move: up and down therewith WVith these general others as hereinafter appear, consists in certain novel and titres of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure 11, is a; fragmentary plan" view of a mattress embodying my invention. Fig. 2 side view of portion of the same; Fig, 3, is an end view on a reduced scale, of the frame, the mattress fabric and other parts shown in Figs. 1 and 2, being omitted. Fig, 4, is a section on the line IVIV of Fig. 21 Fig. 5, is a similar view of slightly modified construction, with the mattress fabric and springs omittedu Figs (5, is a section on the line VI-Vl of Fig. 2,

objects in view and the invention In said drawings, ll are the end bars of a frame, said bars being preferably of angle iron, as shown.

2 indicates the side bars, preferably of and i peculiar fea- 1 tubing, and having their ends bent upwardly at 3 and terminating in flattened extremities 4, underlying the end bars and riveted or otherwise rigidly secured thereto at 5. To a secure said end and side bars in rigid relation to each other, inclined truss braces (5 are employed, the arch portions of said braces being secured to the central portions of the adjacent end bars. The ends of the 1 truss braces underlie and project beyond and are secured to the side bars 52, inward of the upturned ends 3. The truss braces are preferably of angle iron, as shown most clearly in Figs 2, 4: and 5, and their hori- Zontal arms are adapted to rest upon the side rails of a bed, as hereinafter explained, and their depending arms are cut away to pro- ;vide shoulders 7, for engagement with the inner edges of said side rails, the latter be- By this construction and ar 'angement of parts, it will be seen that the mattress frame 1 rests upon the side rails of the bed and tends to hold said rails in engagement with the head and foot ends, not shown, where such 1 ends are provided with sockets and the side rails with lugs to engage such sockets In 1 this connection it will be noted that the up- 1 turned ends of the side bars and the outwvardly projecting ends of the truss braces iconstitute corner risers and obviate the :recessi-ty of using the customary heavy castii-on corner risers common in mattress frame construction.-

9 is a Wire fabric or mattress connected at its ends by the usual hclicals 10, to end bars 1, it being noted that the truss braces 6 iguard against inward bending or bowing of the end bars under the pull imposed thereon by said fabric. To prevent the truss braces from yielding or springing and thereby imposing endwise pressure on the side irails 8, tending to spring or bow the same be employed, the same bridging the spaces between and secured to the undersides of the extremities of the truss braces,v the rivets 12 or equivalent fastening devices by which the truss braces are secured to the side burs, being 1 utilized to also secure the ends of the cross 1 braces 11 to the truss braces.

For the purpose of trussing the wire l fabric 9,. I provide four trusses constructed ins follows2-13 are standards ar'augcd at outwardly, cross braces 11 may opposite sides of the fabric near its ends,

ing indicated in dotted lines, at 8,111 Fig. 3.

' Fig.

the lower portions of the standards under lying the fabric as shown in Figs. 1 and 4. In the preferred construction the standards 13 are split at their lower ends and bent to form open spring sleeves 14:, to fit around the side bars, and short legs 15, to rest upon the ends of the truss braces at the outer sides of bars 2, the lower ends of the legs being recessed to form tongues 16 to bear against the inner sides of the ends of the truss braces as shown clearly in Figs. 2 and 4. By this arrangement the standards 13 are capable of being swung inwardly upon the fabric 9, and secured to the same in any suitable manner for convenience of shipment, the helicals 1O yielding sufliciently for this purpose. The sleeves 14 constitute the pivotal points in such movements of the standards. The engagement of the legs 15 with the truss braces prevent the standards 13 from swinging outward when in operative position.

In the modified construction shown by 5, the cross braces terminate in upwardly projecting arms which constitute the standards 13. At their upper ends the said standards 13 are linked to the sides of the fabric at different points by a plurality of elastic connections 17, equipped by preference with helicals 18, to accommodate a limited downward movement of the fabric, and the strain imposed by the fabric through said connections 17 on the standards 13 is resisted by tie rods or wire connections 19 between the upper ends of said standards and the adjacent end bars of the frame, as shown clearly in Figs. 1 and 2.

In Fig. 5, a modified form of the fabric brackets is shown, the standards in said figure, being shown as upward extensions of the braces 11, and in this construction the upper ends of said extensions or standards are preferably connected by tie rods 20, to the end bars 1, the tie rods 20 extending downwardly and inwardly to prevent outward bending movement of the standards.

The standards 13 and connections 17 and 18, tend to prevent lateral movement or spreading of the ordinary mattress, not shown, adapted to rest upon the wire fabric mattress, and to cooperate in thus properly retaining said ordinary mattress on the fabric, 1 provide one or more side guards. Each of these guards, consists of a piece of wire bent to U-form and then both arms of the U are bent so that the guard in side view shall be of step form, consisting of the tread portion 21, riser 22, projecting upwardly from the outer end of the tread portion and a riser 23 depending from the inner end of the step portion and extending slidingly through holes 24 in the side bars 2 and terminating in laterally projecting portions 25 to limit the upward movement of the guard. The tread portions 21 of the guard are preferably bent at 26, so that their inner portions may lie in substantially the plane of the fabric 9 and at the junction of the inner ends of the tread ends of the risers 23, the guard is formed with eyes 27 receiving longitudinal strands or links of the said fabric, so that when the latter is depressed or springs upward, the guard will slide downward or upward respectively, it being noted that the'outer riser 22 occupies substantially the same vertical plane as the corresponding side edge of the fabric and projects upwardly therefrom for the purpose of preventing undue spreading movement of the ordinary mattress.

From the above description it will be apparent that I have tress embodying the features of advantage enumerated as desirable, and I wish it to be understood that I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim:
