"'f inlthefdrawingfdzhenumenalrrtmdesienatesianetsatiatheaendssthereof. Theeentifeffbedwmgmnit 3 is thus held together at its lower end by the transverse wires I4 which join the springs into a unit, and by the marginal or peripheral wire I5 which secures the spring unit to the border wire I2 and facilitates the securing of the bedspring unit to the base spring I D.

At the upper ends of the spring I3, a similar structure is had, transverse, helical, joining wires I6 extending transversely of the mattress and spring .structure between adjacent transverse rows of the springs I3l and connecting the upper portions of said springs into a unit. An extra heavy border wire I'i, similar to the wire I2,'is also provided at the upper ends of the springs I3` and is secured to said springs by a marginal or peripheral, helical securing Wire I8,'similar to the wire I5 and securing the border fwire I1 to the springs I3 in the same manner.

The innerspring portion of the mattress partV of this new structure isl constructed similarly to the bedspring just described, having an upper border wire I9, a lower border with a multitude of helically coiled springs 2l disposed therebetween and therewithin. The springs 2l are of somewhat lighter construction than the springs I3 and hence yield much more readily. The

springs 2| are joined at their upper ends by cent transverse rows of the lower springs I3 and the upper springs 2l but also join the upper and lower sets of springs together. With this structure, each of the upper springs 2i is held in vertical alinement with the lower springs i3, and

since the two springs are substantially the same diameter, a dependable and secure supporting of the upper springs by the lower springs is achieved. At the same time, a marked degree of flexibility is imparted to the mattress because of the inherent resiliency of the securing wires I6 which permit limited movement of the columns of y A springs with respect to one another.

For further securing together the mattress innerspring unit and the bedspring unit, the heavy border wires I'I and 2i! at the upper end of the said spring unit and at the lower end of the mattress innerspring unit, respectively, are joined together at intervals by wide, substantially C-shaped clips which are deformed into clipping engagement as shown in Fig. 1 and lock the two border wires together in vertical alinement and superposed relation.

The upper surface of the mattress innerspring unit as well as the side and end walls of both spring units are covered with a layer of sisal fabric 26, or other suitable material which will constitute a 4bearing surface for the mattress padding or felting. Over the layer of sisalis placed preferably a relatively thick layer 2l of padding material known in the trade as hair latex. This is an extremely resilient and nonpacking pad formed of hair or suitable fibers to which additional resiliency has, been l,imparted 4 a pad 28 of similar dimensions and thickness composed of any suitable felt formed from vegetable or animal ber. This layer 28 of felting is preferably cotton felting, but it is obvious to persons skilled in this art that other materials or felts may be employed. It is to be noted that the two pads or felts 21 and 28 cover the upper surface of the mattress innerspring unit and extend downwardly around the side and end walls vor vmarginal portions of both the upper and the lower spring units, but terminate at the upper surface of the base frame I0. Since this mattress and spring structure is not adapted to be turned, as is necessary with the usual type "of mattress, there is no need for padding on the underside of the structure and a material saving may be effected by omission of this padding which is' not required. The pads are covered and held in place by the usual ticking 29 which overlies the upper surface of the mattress structure and extendsv downwardly around the sides thereof, the lower, edge of the ticking being turned under the base frame I0 and secured thereto as by tacking, or any other suitable manner. Also, a d'ust cloth or cover (not shown) may ,be secured to the underside of the frame I0, if desired, to close off the same andv to prevent the entry of dust into the interior of the mattress and spring structure.

With the invention described, a combination mattress and spring unit is provided which need not be rotated upon Vthe bed frame or stead as is usually required, and which does not require turning so as to present alternately the upper and lower surfaces of the mattress for reclining purposes. The vertical alnement of the upper and lower springs I3 and 2I and their securing together by the joining wires I6 cause the combnation structure to be exceptionally stable and durable and not subject to deterioration or breaking down because of'misalinement or improper supporting of the spring coils. At the same time, an undesirable rigidity and lack of resiliency normally occurring in structures of this type having adequate securing means for the spring coils, is entirely eliminated because of the springy and resilient nature of the helical joining wires which are employed throughout. These wires hold the springs in a proper fashion, but do so in a yielding or yieldable fashion so that undesirable stiffness in the mattress is eliminated.

Further, it is obvious that a combination mattress and spring constructed in accordance with this invention permits the manufacture of a highiquality product at large saving and therefore the selling of such a product at an economical price. Unnecessary padding and ticking is eliminated and needless duplication of elements in the bed spring structure and in the mattress structure is completely avoided.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, rwithf out departing from the spirit 'of the invention.
