MATTRESS SHIELD.

Application fledmelember 10, 1925. serial No. 74,475.

My invention relates to a new and useful protecting shield for mattresses and the like, the object of my invention being to rovide a combination of primary and secon ary, or

protecting sheets for mattresses and the 11 e, whereby, a smaller or upper auxiliary sheet may be replaced on the main or lower protectin sheet at a relativel low cost, while the mam or lower sheet isle intact and fresh at all times.

With the above ends in view, my invention consists of a lower or main and an upper or auxiliary protecting sheet, each formed of a suitable impervious or water proof sheet material, suchas bituminous or other water proof paper and preferably, creped paper.

My invention further consists of means for retaining the main or lower protecting sheet upon the mattress in position and further means for retaining the upper or smaller auxiliary sheet upon said main or lower sheet in spaced relation thereto and in a detachable manner.

For the purpose of illustrating my invention, I have shown in the accompanying drawings, forms thereof which are at present preferred by me, since they will give in practice, satisfactory and reliable results, al-

though it is to be understood that the. Various instrumentalities of which my invention consists' can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and.

Figure 5 represents one end of a section,

similar to that shown in Figure 3, showing a modified means for attaching the auxiliary to the main sheet. 1

- Figure 6 represents a perspective view,

similar to that shown in'Figure 4, showing a modified construction.

Referring to the drawings, in which like reference characters indicate like parts, 1

designates a mattress shield of my novel construction, consisting of the bottom or main sheet2, and the upper or auxiliary sheet 3.

The main sheet 2, of the full size of the mat-' tress, is retained thereon by suitable stra s or fiexlble bands 4 which are secured in t e end seam 5 thereof,.which flexible bands are tucked underneath the mattress, between the mattress and the spring. The n per or auxillary sheet, of substantially smallersize,-is po- 2 by a series of-suitablestraps 6 secured to each corner thereof, which straps ma be detachablysecured to the main sheet, a series of snap fasteners 7, as shown in F igurcs 1,3, 4 and 5, or maybe merely tied to lVhile the sheets 2 and 3 may be 'made of any suitable Water proof material, a suitable water proof creped paper has been found, in.

practice, to be very desirable" and to give highly beneficial results, since such sheets of waterproof creped paper possess the resiliency and elasticity essential to comfort.

Similarly, while the retaining straps 6 and 9 may bemade of any suitable material, it

has been found that a strip of creped paper serves the purpose very well, also due to its elasticity and resiliency, by allowing for the slight shifting and moving of the upper or auxiliary sheet with respect to the lower or main sheet.

By my novel construction it is thus seen,

tected from all moisture, by the twosheets of water proof material 2 and 3, but also by the provision of the small auxiliary sheet 3 upon the lower or main sheet 2, at the place where said main sheet is most exposed to dampness'or moisture, the lower'sheet may be protected and thus maintained fresh and clean. for a great length of time by merely replacing, from time to time, the upper and that not only is the mattress entirely proa sitioned and retained upon the bottom sheet a novel and useful construction in a mattress shield which embodies the features of advantageenumerated as desirable in the statement of the invention and the above descrip- I -tion and while I have, in the present instance,

shown and described a preferred embodiment thereof which will give in practicesatisfac tory and reliable results,. it is to-be understood that such embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the mvention or sacrificing any of its advantages.

Having thus described my invention, what I claim asnew and desire to secure by Letters Patent is 1. Ashield of the character stated,comprising a lower main sheet of water proof creped paper, straps extending transversely from naeesa the corners thereof, an upper smaller, cen-' trally disposed auxiliary sheet of water proof creped paper, and means intermediate said auxiliary sheet and said lower sheet for detachably securing the former to the latter, said means comprising parallel, inwardly extending straps secured to the ends of said lower sheet, aligning straps secured to the corners of said upper sheet and fastening means for the juxtaposed ends of said straps. 2. A mattress shield of the character stated,

comprising alowe'r main sheet of waterproof material, fastening straps extending transversely from thecorners of said lowersheet, short, inwardly extending reinforcing straps on the upper surface of said lower sheet, an upper auxiliary sheet of waterproof material, of lesser area than said lower sheet, fastening straps aligning with said short straps and extending longitudinally and outwardly front-the corners of said upper, aux; iliary sheet and means for detachably securing the outer ends of said fastening straps to the inner ends of said'reinforcing straps.
