Patented Dec. 10, 1935 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to sanitary appliances and special reference to a sanitary seat appliance for water closets.

One important object of this invention is to provide a novel seat appliance in which the seat is formed by spaced rolls covered with paper.

A second important object of the invention is to provide novel means whereby fresh paper is made available each time the seat is used.

A third important object of the invention is to provide a novel arrangement of spaced paper covered rolls for this purpose having actuated means for feeding used paper off the rolls.

A fourth important object is to provide novel means for severing the used paper from the supply of paper.

A fifth important object of the invention is to provide a novel arrangement of this kind wherein the used and severed paper is disposed of automatically and without the necessity of handling such paper.

With the above and other objects in View, as will be presently apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters indicate like parts in the several views, and:-

In the present illustration of the invention there is disclosed the usual water closet bowl 10 having a rearward extension II. The usual seat is removed and the present invention is utilized in place thereof. The invention itself includes a rear frame bar l2 extending transversely of the rear part of the bowl and having rearwardly extending feet 13 resting on the extension II and secured thereto by bolts l4. Bearings 15 on the feet l3 support a shaft l6 and on one end of this shaft is fixed a sprocket wheel H. Bevelled gears iii are fixed on the shaft and mesh with similar gears 19 fixed -on shafts 20 having their rear portions journalled in bearings 2| at the ends of the bar F2. The forward ends of the shafts 20 are journalled in bearings 22 formed on the ends of a front frame bar 23 which has its central por- '5 tion resting on the front of the bowl H1. Each shaft 20 has a drum 24 fixed-thereon between the bearings '21 and 22.

Rotation of the shaft H5 in the direction of the arrow}; -(Figure 3) will cause the drums to rotate 1 in the directions shown 'by the arrows B in Figure 2.

A casing 25 surrounds the water closet and covers the gearing at the rear of the device. This casing is provided internally with a sup- 15 porting frame 2-6. Idler sprockets 21 are mounted at the front and rear of this casing adjacent the bottom thereof. A third idler sprocket 28 is mounted in the casing directly above the front sprocket 21 and to the rear of this sprocket 2B 20 is a fourth idler sprocket 29.

An endless sprocket chain 30 is led around the-sprocket H and the idler sprockets as shown in Figure 3 so that this chain has a vertical portion 3| at the front of the casing. A bracket 32 5 is fixed to the rear portion of the frame 26 and a lever 33 has its rear end pivoted to this bracket and extends forwardly through -a suitable vertical slot in the front wall -'of the casing 25.

A pedal 34 is carried by the projecting end of 30 the lever and a spring 3 5 normally holds the lever in raised position. A pawl 36 is pivoted on a stud '3! fixed to the forward part of the lever 33. A spring 86 normally holds this pawl in engagement with the vertical run 31 of the chain so that depression of the lever 33 causes movement of the chain in the direction of the arrow A while in the -lifting of the lever by the spring 35 the pawl rides over the chain. Thus, each time the pedal '34 is 'steppedon-and forced downwardly 40 the drums will be rotated in the directions of arrows CB.

Rolls 39 of a suitable grade of paper are held in the lower part of the casing and paper from these rolls is led up to the outer sides of the drums 23, over the tops of the drums and down the inner sides. Idler rolls 40 mounted on spring arms 4| serve to press the paper firmly against the drums and cause proper feeding of the paper as the rolls are rotated.

Hinged plates are provided at the sides of the casing permitting access to the paper compartment. Extending between the frame bars I 2 and 23 are fixed knife blades 42 which carry guide fingers 43 entering grooves '44 in the drums 24 of the drums.

so that the paper is guided over the tops of the blades 42.

Above and in cooperation with the blades 42 are vertically movable blades 45 having ends which enter slots 46 in the frame bars [2 and 23. Springs Al in these slots hold the blades 45 normally spaced above the blades 42 so that the paper may pass freely between each pair of cooperating blades. Adjusting screws 48 serve to regulate the spacing of the blades. The blades 45 are provided with spring arms 49 carrying idler rolls 55 which press against the paper and assist in ensuring proper feeding thereof and also to hold the paper smoothly on the drums. Each movable blade is provided at each end with an operating lug 5| and these lugs lie in the path of operating fingers 52 carried by the ends These fingers are preferably in the form of pins fixed in the drums and having rollers mounted thereon. From an inspection of Figure 1 it will be seen that the central parts of the drums overhang the bowl IE The ends of the drums are preferably crimped to better grip the paper and prevent tearing thereof.

Obviously, the cutting edges of the blades may be either horizontal as shown or inclined.

A guard 53 is secured at 54 to the bar 42 and protects the paper and cutting mechanism from water that might splash from the bowl. A slot 55 in the lower portion of the guard permits egress of the used paper.

A disinfectant may be applied to the seat rollers by means of a wiper 56 in the form of a felt strip which is supported in a trough 51 and held in contact with the rollers by means of springs 58, the trough also serving as a reservoir for the disinfectant. It will be apparent from an inspection of Figure 1 that a supply of disinfectant may be introduced from above at either end of the trough 51.

As previously stated, depression of the pedal 34 operates the drums which have their upper parts covered with paper and together serve as a seat. Operation of the drums causes the used paper to be rolled off and to pass between the knife blades until the fingers 52 engage the lugs 5| which causes depression of the movable. blades and severing of the paper. The severed pieces drop into the bowl I!) and are carried 01f by the usual flushing operation. Simultaneously, unused paper is drawn from the supply rolls 39 and covers the drums.

There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

It is obvious that changes may be made in the form and construction of the invention without departing from the material principles involved. It is not, therefore, desired to limit the invention to the exact form herein shown and described, but it is desired to include all forms which properly come within the scope of the claims.
