SANITARY WATER-CLOSET ATTACHMENT.

Application filed October 8, 1921.

T0 all whom t may concer/11,.'

Be it known that L WARREN C. Runs, a citizen of the United Sta-tes, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Sanitary 1Water-Closet Attachments, of which the following is a specification.

The present invention relates to sanitary water closets of' the type shown in my prior patents wherein seats arranged at each side ot the toilet fixture are covered with a covering strip, and in connection with which means are provided for shifting the strip f so as to expose a fresh, clean surface prior to each use of the toilet.

The object of the present invention is to produce an apparatus of this character at moderate cost and of such construction that it can be applied with the' greatest possible ease to existing toilet lfixtures and used inprivate homes or places of semi-public character where the more complete protection from contamination of the seat and its covering given by the machines and devices disclosed in my prior patents is not so important as is the case with water closets provided for use of the general public.

With this obj ect in view the invention conso Sists in the new combinations and features of construction and arrangement described in detail in the following specification ,and pointed out in the claims.

ln the drawings furnished with this spec 5 icatiom- Figure l is an elevation from the rear of a toilet fixture with the aseptic seat made according to the present invention applied to it; the seat and paper supy plying means at one side of the fixture be? ing shown in section and that at the other side being shown in elevation.

Figure 2 is a plan view oit a part of the fixture and equipment., the seat and papersupplying means at one side of lthe fixture being fully shown. y Figure 3 is an elevation oi the paper supplying means as it the enclosing casing were cut away substantially on line 3-3' of' Figure 2. y

used with fixtures of this character for mounting a superposed seat. The apparatus in which my invention resides is an attachment for such a bowl or fixture consisting of two duplicate units7 each having a seat or seat member l and suitable means for holding a paper covering strip (or a strip of any other suitable material) stretched over the seat and for feeding the strip' so as to ex* pose fresh, clean areas on 'the upper side of the seat. Although the two duplicate seats or seat members together are practically necessary to furnish the support for the occupant of the closet, each is called in this specification a seat for convenience. The two duplicate units of the attachment are connected together by a cross bar 5 having lugs 6, 6, adapted to be mounted on the pintle rodB in the same manner as the ordinary toilet seat, in substitution for the latter inV fixtures already installed, and with the same capacity for being swung upward and backward out of the way, .when need of so doing arrives. In addition to being partially supported by means of this connection the seat units also rest upon the rim of the bowl, but are not otherwise supported. These units are parallelto each other and spaced apart by a distance which has been plying and feeding means are mounted.

This basefraine 'may be madey as a casting and is formed with a horizontal web 7 overlapping the side of the fixture and having ribs 8 on its under side which rest on thc rim of the fixture. At 'the ends oit the webs 7 are upright Webs) on which rest the endsl of the seat proper 10, which is preferably a wooden board and is made tast by screws to lugs ll on the webs 9. Rolls 12 and 13 at the inner and'outer edges of the seat are journaled in the webs 9 andV guide the covering strip around the edges oi the seat without frictional drag. Extensions 14 of the webs 9 project outward from the fixture and from them depend webs or plates l5 by which are supported the paper supply and Cit take-up spools and the paper feeding device presently described. Lips 16 and 17 extend horizontally in opposite directions from the upper edge of the web extensions 14, and the lips 17 are carried downward at a distance from these extensions.

The frame consisting of the parts last de'- scribed may be made as a single integral casting, which is preferred on account of its low cost, or it may be fabricated of separate members suitably secure-d together. A brace B extends between the lower ends of the two depending' frame members 15 to hold them at a fixed distance apart. This brace is here shown as a tube, but it may be of any other suitablev construction.

The supply spool previously mentioned consists of a central tubular body 18 and heads y19 and 20, they head 2O being fixed to' one of the frame members 15 and the head 19 having a trunnion 21 which is movable endwise through the opposite frame member and is pressed against the tube by a spring 22. The take-up spool consists of a tubular body 23 and heads 24 and 25. The head 24 has a tubular trr'mnion 26 wh-ichis mounted rotatably in` one of the frame members 15, while the' other head 25 is adapted to turn freely about a shaft 27 which rotates in the opposite frame member 15 and is rotated by a sprocket wheel 28-1and chain 29 presently'described in detai A friction clutch consisting of a disk 30, made lfast to the shaft 27, and a spider 31 affixed to disk having spring arms compressed between this disk and the head25, imparts' rotation to the latter for' winding up the used strip. Independently connect-v ed to the head 25 is an annular ratchet 82 with which cooperates ay pawl 83 pivoted atl 34 to the adjacent frame member 15 and held by gravity in contact with the ratchet. Tov the head 25 is connected a hub 85 having a key 86 which engages a slot in the tube 28, and a disk 37 is connected to the hub. A rod 38 passes through the tubular trun'nion 26 and carriesv a knob 39 on its outer end. lits inner end is screwed into the disk 37. By unscrewin'g and witlr drawing this rod the head 24 is released from the head 25 and may be moved outward far enough to release the tube 23, whereby a tube filled with used paper may be removed and an empty tube substituted. Similarly by pulling outwardly on the knob 40 which is secured to the trunnion of head 19, this head may be disengaged from the tube 18 of the supply spool and the latter removed when empty to make place for a full tube carrying a new roll of clean paper.

The paper covering strip and also the cover 52 are omitted from Figures 2 and y 8. in order not to obscure the illustration of the frame and mechanism in those figures.

One of the strips is shown in section and the other in elevation in Figure 1, and both are designated by the letter P. Each strip passes from its supply spool over the roller 13 at the outer edge of the seat, thence over the upper surface of the scat and around the roller 12 at the inner edge, thence over a guide roll 41 journaled at its opposite ends in the frame members 15, and thence across a feed roll or feeder 42 to the take-up spool.

The feed roll is supported by two swinging plates 43 and 44 which are mounted on the opposite ends of a shaft 45 having its bearings in the depending frame members 15. These plates are essentially arms and have hubs which surround the ends of shaft 45 and are secured thereto by taper pins 46. These two plates or arms, together with the shaft on which the feed roll 42 is placed (such shaft being secured at its ends in the plates) constitute a swinging frame or swine'. The plate or arm 43, which is at the forward side of the mach-ine, carries an eye 47, and from the eyes 47 of the two swinging frames, at opposite sides of the toilet fixture, is hung a bar 48 by means of links 49. This bar is depressed in its middle part and provides a treadle hanging at the front side of the toilet fixture near the fioor. It is adapted to be pressed upon by the foot of the user of the toilet and when depressed, as shown in dotted lilies in Figure 1, it carries the two swinging frames downward, moving their rolls 42 toward the fixture, across the line between the take-up spool and guide roll 41 of each unit. A chain 50 is connected to the treadle bar 48 nea-r each end and hung from the frame members 7 of the adjacent unit. These chains arrest the bar 48 when both swings have been moved far enough to draw off ysuch a length of paper as will provide a fresh covering for the scat and compel equal movement to be given to both swings, as later explained.

A rod 51 having its ends offset and journaled in sockets in the web extensions 1-lrests on that stretch of the covering paper between the supply roll and the guide roll 13 to' maintain tension in the paper and take up any slack due to additional pa per being drawn from the supply roll by shifting of the occupant on the seal.

A cover 52 overlics the upper end of the frame outside of the seat, and is pivoted to the frame by means of lugs 53 on the cowland 54 on the frame and a pintle 55 passY ing through said lugs. The outer.v rear, and front sides of each unit are enclosed and guarded by a shield 56 fitted to the webs or lips 17 of the base frame and detachably secured thereto. This shield surrounds and underlies the fixed frame, except at the side next tio the toilet fixture, and its bottoni Cil wall 56EL has an opening through which projects a headed stud 57 which is fixed in the brace B. A hook-shaped latch 58 is pivotedto this wall by a stud 59 and its hook is adapted to swing so as to embrace the shank and overlie the head of stud 57, thus affording means by which ready attachment and detachment of the shield may be effected. rllhe take-up spool and the paper adjacent thereto are guarded on the side next to the fixture by a shield 60 secured to lugs 6l and 6la on the arms 43 and 44 of the swing.

The chain 29 previously mentioned passes around the sprocket 28 on the take-up spool 27 and around an idler sprocket 62 arranged in the same plane with the sprocket 28 and supported by the main frame in a manner permitting it to be adjusted so as to take up slack in the chain. The sprocket support is a stud 63 fixed yin a plate 64 which is pivoted to one of theA frame members by a stud 65 `and has a transverse slot or notch occupied by a clamp screw 66 which is set linto the frame. Such slot or notch permits angular movement of the plate, and by tightening the screw 66 these adjustments may he made permanent. The adjacent plate 44 of the swing carries an arm 67 pivoted by a stud 68, and fastened to the upper end of arm 67 are two straps 69 which embrace one stretch of the chain 29 and between which at their ends is fastened a finger adapted to enter the links of the opposite stretch of the chain. The arm 67, straps 69 and finger 70 together constitute a driver adapted to drive the chain in the upward movement of the swing and of which the finger is so shaped that it readily withdraws from the chain and enters the nearest opening in the chain when the swing rises. A guide 7l is attached to the base frame parallel with that stretch of the chain which the driving linger engages in order to ensure engagement there-` with of the finger in case the chain should be slack. The arm 67 of the pawl or driver is pressed upon by a spring 72 which is coiled around the pivot stud 68 and reacts against the adjacent arm 44 of the swing so as to maintain the feed nger in position to engage the chain. The spring Amay. be omitted and gravity alone depended on to effect such engagement, since the center of gravity of the feed pawl is at the side of the pivot 68 toward the chain.

A spring 73 is attached at one of its ends to the arm 43 of the swing frame, and at its opposite end to a stud 74 on the fixed frame, in each unit; the tendency and effect of such spring being to raise the swing frame whenever the treadle is released after having been depressed.-

The operation is as follows: Before using the toilet, the user presses withy his foot on the treadle bar 48 until the latter is depressed to the limit allowed by the 'chains 56. This action swings the paper drawing rolls 42 across the line of the paper, and downward, and thus causes enough paper to be drawn from the supply rolls across each seat T to provide a fresh surface, for the take-up rolls are then prevented by their pawls 38 from turning. Equal feed of paper over each seatl is produced because movement of the treadle bar is not arrested until the slack in both chains has been taken up, wherefore even if one of the paper feeding swings should move more easily than the other, and therefore act in advance of the other, the

movement of the treadle bar will continue Il until the more reluctantly moving feed swing is operated, owing to the natural tendency of the operator to maintain the pressure on the treadle to the limit of its possible movement. During this action the feed finger is carried down to a low point in the outer stretch of the chain29 in each unit. When the operato-r removes his foot from the treadle bar the returning'r springs of the paper feeders restore them to their f the paper left slack by the return of the slack will be wound up even when thediameter of the take-up spool is the smallest, the condition when a new strip is first applied; and the friction clutch between the driving spindle and adjacent head of the take-up spool is adapted to slip when the spool has become enlarged by windings of paper on it. Thus under all conditions all of the slack of the paper is wound up and an even tension is maintained on the paper,

and the drawing off or feed roll is allowed to return to that position from which its range of possible movement is great enough to draw off from the supply spo-ol a length of paper substantially equal to, or slightly greater than, the width of the seat.

Then all of the Ipaper on the supply spool has been thus used up and transferred tothe take-up spool, the tubular centers of these spools may be removed, a new roll of paper substituted 1n the supply spool and an` empty tube substituted in the take-up spool; the shield 56 having first been removed to give access to the knobs 39 and 40, and being` afterwards replaced.

I have referred to the sanitar i cov-crine of the seat as a paper strip because paper` is the material which ordinarily will be used for the purpose. I wish it to be understood, however, that if any occasion should arise for using other 'material than paper for this purpose, the use of surh othematerial' inan apparatus corresponding to the intent of the appended claims would be` witlrin the scope-lor which I claim' protection for the invention.

It is" to be understood also that various modifications in construction. and arrange nient of the various parts or' the apparatus may be made witl'rin the same scope of prov tection; Thus, for' instance, although I have described and shown a link chain as the driver for the take-up speohl consider as equivalent thereof, and intend to protect by the appended claims, any flexible driving device, such`- as a belt or strap, whether perforated or not, which functions in a similar manner to the: chain here shown.

yLikewise' similar equivalents are within the intended scope of my claims as related tol other parts of the combination.

What I claim and desire to secure by Let ters Patent is l. sanitary toilet' comprising a seat proper normally stationary and occupying a horizontal position over the toilet xture, supply and taire-up spools for a covering strip supported adjacent to said seat, guide members arranged to guide the strip over and under and around one edge of' the seat to the respective spools and a draw-ofi." device arranged to bear on the strip between one of said spools and one olr sai-d guide members and movable away from they line between said member and spool, whereby is enabled to draw lengths of the strip" from the supply spool, the take-up' spool being withheld from rotation in the unwinding direction.

2'. A sanitary seat for toile-ts comp-rising a seat proper, a covering strip extending over and under said seat and around one edge thereof, a sup-ply spool from which the strip leads to' the seat, a taire-up spool to which the strip vis led `from Ithe Seat, a guide around which the strip passes in going from one of the rolls to the seat, an o'scillative swing including a draweof mein ber arranged to engage the strip between the last-named spool and guide and being movable with that part of the strip on whih it bears away from the line between said spool and guide, means engagingA the take-up spool to prevent unwindin'g moyeme'nt thereof, a sprocket connected with the take-upspool, a" chain passing around and in mesh with said. sprocket, and a driver carried by said swing constructed to connect with said chain and apply a driving impulse thereto during the return of the swing after operation thereof in the manner described.
