No. 883,538. s cification of Application filed To all whom it may concern:

Be i known that I, THOMAS T. GRASER, a

citizen of the United States, residing at Rochester, 1n the countyof Monroe and-State of- New'York, have invented new. and useful Improvements in Toilet Roll Paper Holders, of which the following is a s ecification.

:This invention relates to hol ers for rolls. of toilet paper, andit has for its object to .provide a device which shall be operable by of the ratchet wheel in the opposite directionthe movement'of the closet seat to expel from the casingof theholder a predetermined length of paper which shall be capable pf being conveniently and accurately regu ater. i Further objects 'of the invention are to simplify and improvethe'construction and operation of this class of devices. With theseand other ends in view which will readily appear as the nature of the in-.

ventionis better understood, the same consists in the improved construction and novel arrangement and combination of parts whichwill be hereinafter fully described and particularly ointed out in the claims;

In t e accompanying drawings has been illustrated a simple and 'preferredfor'm of the invention; it being, however, understood that the line 33 in Fig. 1..

are denoted by no limitation is necessarily made to the recise structural details therein exhibited, ut that changes, alterations. and modifications within thescope of the invention may beresortedito when desired. A In the drawings, Figure 1 is averticalsectional view showinga-roll paper holder and means for operating the same, constructed in accordance with the invention. Fig. 2 is adetail side view of a portion of the casing. Fig. 3 is avertical sectional view taken through the casing on the plane indicated by Corresponding 1parts in the several figures i e characters of reference. A suitable-casing A is rovided with bearlugs for a shaft in onw ich a roll 20f toilet paper is supporte in the usual manner paccess to the casing being had throu h a door 3 sight opening4. The casingjA is. rovidedw th the discharge slot-5 to which t e paper 1s guided between a pair of suitably sup ported

pressure rollers

6 and 7 which are sup ported for rotationupon-their respective shafts, and one of which is ositivel 0 eratedby means to be present y' descri e for Letters Patent. Patented March 31, 1908.

the purpose of expelling or discharging the pa er through the slot or aperture 5.

, The shaft 8 supporting the roller 7 also supports a ratchet wheel?) having a pinion thereof. The ratchet wheel 9 is in engage ment with spring actuated pawls 11 upon one end of the roller 7 so that, Whenthe ratchet wheel is rotated in one direction the roller will be rotated thereby while rotation will cause it to slip idly by the pawls 11; reverse rotation of the roller 7 is prevented by a dog or pawl 12 which is pivoted upon the wallet the casing adjacent to the end of wheel 13 suitably connected with said roller. The ratchet wheel 9 is actuated by means of a suitably supported pivoted rack seg-' ment 14 that meshes with the pinion 10 10-formed upon or connected with one side -Whi0h'lfitt61', as-hereinbefore stated, is se-' 'the roller in engagement with a ratchet.

said set screw alsoengages a slot 19 in the side wall of the casing A'Where it may be readily secured at various adjustments, thus shifting the vfulcrum of the lever 16 and 'of the leverwhich is connected by the link .13 with the jracksegment 14, and consequently gaging'the extent'of the movement of said rack segment.

closet seat 21 which has a limited vertical movement. .Suitably mounted and sup- 'posed cy inder 22 wherein operates a piston 23 which is normally'forced in an upward direction by means of a spring 24 within the cylinder; the latter contains a suitable fluid 25, preferably of a viscous naturesuch as oil,-glycerin or the like, although water,

regulating the length of the throw of the end 20 designatesa casing supporting the ported u on the casingv 20 is a vertically dlS-9 alcohol or other similar liquid may be used,

-wardly openingvalve 27, and said'piston' is Which willbe thereby supported in a raised position; the piston 23 also has a downward if preferred. The piston is rovided with a port or passage 2'6-prov1de with an /upalsoprovided with a leakage port or bleed aperture-28. A piston rod- 29 extending u extending rod 30 having a yoke or extension 31 which is guided through an aperture 82 in the bottom of the roll paper casing A, and is pivotally connected with the lever 16. The heads, or ends of the cylinder 22 are provided with packing glands 33 surrounding the piston rods to prevent leakage.

When the closet seat 21 is depressed, the piston 23 is forced downward in the cylinder 22 against the tension of the spring 24, the liquid contained in the cylinder passing through the valve port or passage 26 in the piston from below the piston to the upper end of the cylinder. The piston rod 30 and its extension 31 actuates the lever 16, the throw of which has been previously determined by proper adjustment of the set screw 17, which constitutes the fulcrum of the lever; the rack segment 14 will thus engage the pinion 10 causing the ratchet wheel 9 to engage the pawls 11, thus rotating theroller 7 and causin a length of paper to be delivered by the

ro lers

7 and 6 through the slot or aperture 5 where it may be readily torn off. When pressure from the seat 21 is relaxed, the piston 23 will be restored to its initial position by the action of the spring 24, but the movement of the piston in the cylinder will be obstructed by the liquid contained in the latter which, when the piston is forced upward, will be compelled to pass from the upper to the lower end of. the cylinder through the leakage port or bleed aperture 28 in-the piston. 1 The time occupied by the piston in gainin its initial position will be governed ,partly y the area of the leakage port, and also by the consistency of the liquid contained in the cylin- It will be seen that by this invention, only a predetermined quantity of paper will be expelled from the roll paper casing at each operation; it will also'be seen that an interval of time must necessarily occur after each operation before the apparatus is restored to its initial position for a repetition of the operation. Wastage of paper is thus positively prevented, and the apparatus being atomatic in operation, will supply the quantity ofpaper previously determined upon with certainty and accuracy, without personal attention.

Havin thus fully described theinvention,

' what is c aimed as new is:

1. In a device of the class described, a casing having a discharge slot, a roll of'paper supported for rotation in the casing, a palr of f e rollers, means for positively actuating one of the feed rollers, means fqrregulating the extent of the movement of the positively segment rack, an adjustable fulcrum for the lever, and means for actuating the lever including a cylinder, a valve spring actuated piston operating therein and having a leakage port, liquid contained in the cylinder, a yoke connecting the piston with the lever, a rod extending upwardly from the piston, and a vertically movable seat supported upon the iston rod.

8. In a device of the c ass descr bed, a roll paper casing having a discharge aperture, a

pair of feed rollers supported loosely in pe-' ripheral contact with each other, means for positively actuating one of the feed rollers lncluding a pinion, a rack segment, a slotted lever, and a'link connecting the lever with the rack segment, an adjustable fulcrum consisting of. a set screw adjustable in a slot in-the wall of the casin and engaging the slotted lever, a vertically movable closet seat, and means for transmitting motion from the closet seat to the lever.

4. In a device of the class described, a roll I paper casing having a discharge aperture, a pair of feed rollers supported loosely in peripheral contact with each other, means for positively actuating one of the feed rollers including a pinion, a rack segment, a slotted lever, and a link connecting the lever with the rack segment, an adjustable fulcrum consisting of a set screw adjustable in a slot in the wall of the casin and engaging the slotted lever, a verticaly movable closet seat, and means for transmitting motion from the closet seat to the lever, said means including a cylinder containing liquid, a spring actuated piston operatingin the cylinder andhaving a valved passage for thepassage of the liquid and an auxiliary leakage port or bleed aperture, a yoke connecting the piston with the slotted lever, and a piston rod supporting the vertically movable seat. v

In testimony whereof I aflix my signature .in presence of two witnesses.
