' In Germany February 9, 1935 2 Claims.

Protecting devices for water closets consisting of a paper web with cut out portions for the seat and conducted from an unwinding roll over the seat, to be returned at the 'front end of the seat over a guide roller are known. As the protecting web is conducted back under the seat, the water closet must be adapted to the protecting device so that mounting of such a device on the water closet causes considerable expense. It further happens frequently that portions of the wooden seat remain without protecting paper if the paper is shifted towards the pan by a person sitting down on the seat. A further diificulty is that, when the paper web is being unwound by rotation of a crank handle, the next following cut out portion must register accurately with the seat hole as otherwise in front of or behind: the seat hole a portion of the wood is not covered by paper.

These inconveniences are obviated by the apparatus for protecting closet seats according to the invention in which the paper web is conducted to the winding roller between that portion of the web placed on the seat and the seat. The apparatus according to the invention does not require any changes on the water closet as it is merely necessary to screw the front guide roller on the seat. A double protection is further formed as always two portions of the paper web are lying the one on the other. If therefore the upper portion of the paper is shifted towards the pan by the person sitting down, the lower paper web still covers the edge of the seat hole. Compared with the simple protecting sheets a secure covering of the seat is attained by winding on the used surface of the paper, the not used side turned upwards. It is further no longer necessary that, when a portion of the paper web is unwound, the cut out portion of the paper web registers accurately with the hole of the seat as, if the upper cut out portion should be accidentally pulled forward too far, the lower portion; of the paper web will protect the seat with the upwardly turned not yet used side of the paper web, so that it can never happen that any portion of the seat in front of or behind the hole is not covered by The protecting apparatus according to the invention is illustrated by way of example in the accompanying drawing in. which:-

Fig. 1 shows in front elevation a water closet with the protecting apparatus and flushing device, the lid being omitted on the protecting apparatus.

Fig. 2 is a side elevation of Fig. 1, partly in section.

Fig. 3 shows the protecting apparatus in elevation.

The unwinding roll a and the winding roll b are enclosed in a box 0 adapted to be closed by a lid 01 guided in grooves of box 0 so that only a narrow slit e exists at the lower end of the lid through which the paper web passes. The box stands on the rear end of the water closet and is hung on the wall by means of two holders 9.

The paper web 1 has as usual cut out portions 71 conforming to the hole in the seat of the closet and spaced at suitable distances. The cut out portions h are slightly smaller than the hole 2' in the seat in order that the seat be well covered,

The paper web I is conducted behind a guide roller 9 (Fig. 2) and moves then over the seat It to a guide rollerl and around this roller back over the. seat to a guide roller m inthe box and upwards behind the paper roll a and along a guide roller n to the winding roll I). On the seat It there will always lie a paper portion not yet used and a used paper portion, the not used side of the latter being turned upwards so that a good covering of the closet seat is ensured. The distance between the cut out portions h of the paper web is such that the consecutive cut out portions register the one with the other if a fresh portion of the paper web is pulled over the closet seat by turning a crank handle 0 screwed into the winding roll I). This crank handle can be turned only in clockwise direction to effect the winding of the used portion of the paper web and the pulling forward of a fresh portion of the paper Web. It is impossible to unwind and wind the paper web in the opposite direction. The paper web itself ensures the movement and no chains, belts, cords and the like are necessary.

The guide roller 1 is carried by a resilient steel band 1) which is fixed by means of screws on. the seat k of the closet. This roller 1 can consequently yield when a person is sitting down on the seat so that it is never in the way.

The unwinding roll a and the winding roll 12 are preferably adapted to be inserted in bars r so that inserting and removing does not cause any difficulties, Both rolls may be of wood, same as the rollers 9', Z, m, n. The roll a with the wound up paper web is preferably supplied by the paper mill ready for insertion in box 0. The roll b with the used paper web wound on the same is subsequently destroyed and the empty roll a is then used as winding roll.

In water closets in which the flushing pipe s is behind the closet, the box 0 is out out correspondingly on the upper and lower portion as shown in Fig. 3.

We claim:

1. A closet protecting device, comprising in combination with the closet seat, a paper web having cut out portions corresponding to the hole in the seat, an unwinding roll above the closet seat, a guide roller at the front end of the seat over which said paper web is moved back over the closet seat below the unwound paper web, a resilient steel band fixed by means of screws to said closet seat and carrying said guide roller, and a winding r011 behind the seat above said unwinding roll adapted to wind up the used portion of the paper web.

2. A closet protecting apparatus as specified in claim 1, comprising in combination with the un- Winding roll and the winding roll, a box suspended on the wall behind the water closet, bars in said box, each designed to hold one of said rolls, and guide rollers on the rear wall and near the front wall of said box for conducting the paper web from said unwinding roll and to said winding roll, and a crank handle for rotating said winding r011.
