With the result5 that the surfaces of these rolls are'su'fliciently"close together to grip the extended end' j23 of the paper being unrolled from the supply roll 12. In orderto pprevent slipping vofione of therolls in respect to-the other, enmeshed gears '26 and 27 are made iast to :the shafts 21- and 22, respectively. The rolllt'ris larger than the roll 17, the diameter of the former being a multiple ofgth at of the 'latter preferably the diameter of the r0lli16. being twice that of the roll 17, Withthe result-that the roll 17 will make two complete revolutions ion-each revolution of the-roll 16.; r

A preferably serrat'ediknite -l disposed svithin-and extending longitudinally of the you 16, which. is hollow, iscarried by a-strip '325'WhlCl1' lS movable radially of the roll 116, being carried preferably a pair-f :pins

slidably; mounted in :lugs 34 against each of which-a spring 35 presses,i'urgingthe strip 32'andkni-fe 31 radially outwards in respect =t'oath,erol1* 1f6,'t0 project the knife 31. through a slot 36 in the wall of the roll 16. When in outermost position, the outer or cutting edge of the knife 31, is disposed within a complementary groove 37 in the smaller roll 17. The knife 31 fits sufliciently loosely within the groove 37 to permit the rolls 16 and 17 to turn without interference at the knife 31 with the walls of the groove 37.

Coin-releasable means for holding the rolls 16 and 17 against turning, are provided. The shaft 22 terminates at a point spaced from the inside of the housing 6, and an axially aligned shaft 41 is journalled upon an extension 42 of the frame 8. A disc 43 is rigidly attached to the shaft 22; and a disc 46 is rigidly attached to the shaft 41. An operating handle 47 is rigidly attached to the outer end of the shaft 41, outside the housing 6. A pin 48, rigid with the disc 43, is disposed within an arcuate slot 49 in the disc 46, permitting a degree of play between the two shafts 41 and 22, corresponding to the length of the slot 49, but effecting rotation of the two shafts together after this play has been taken up. A coin recess 51 is formed in the edge of the disc 46; and a coin chute 52 leads from the top of the housing 6 downwards to a point adjacent the coin recess 51, so that a coin deposited in the coin chute 52, will lodge within the recess 51.

A lever 53 is mounted for pivotal move? ment upon a pin 54 rigid with a portion 56 of the framework 8. The free end of this lever 53 is adapted to engage'a projection 57 upon the inner disc 43, in such a manner that it normally holds the disc against rotation. However, when a coin is dropped through the coin chute 52 and lodges within the coin recess 51 which is in the outer disc 46, and then this disc 46 is turned, the rounded edge of the coin will engage the free end of the lever 53 and swing it about its pivot 54 so that the projection 57 of the inner disc 43 will bepermitted to turn therepast when the pin 48 is engaged by the after end of the slot 49. As soon as the roll 17 has turned far enough so that the coin recess is disposed adjacent the'bottom thereof, the coin will drop from the recess to the bottom of the housing 6.

Means are provided for retaining the lever 53 in unlocking position until the cycle of the machine has been completed. Since the roll 17 must make two revolutions for a single revolution of the roll 16, it is important that the projection 57 shall not engage the lever 53 until the roll 17 has made two complete revolutions. A push rod 61 is mounted for sliding movement within brackets 62 carried by the frame 8. A spring 63 under compression betweenthe lever 53 and one of the brackets 62, urges the lever 53 to locking position, whereas'a stronger spring 64 under tension between a portion'of the frame 8 and a bracket 66 carried by the rod 61, urges the rod 61 in the direction opposite to that in which the spring 63 exerts its force. A shoulder 67 onthe rod 61, is adapted to engage the lever 53 and push it from engaging position. A cam 68 is carried by the roll 16 in position to engage a shoulder 69 rigid with the rod 61. This cam 68 is of such configuration that when it is in engagement with the shoulder 69, the rod 61 is withdrawn from that position in which the shoulder 67 presses the lever 53- out of locking position. Furthermore, the cam 68 is so positioned upon the roll 16 that immediately after the lever 53 has been pressed out of locking position by the coin within the coin recess 51, the cam 68 will pass from engagement with the shoulder 69, whereupon the spring 64 will slide the rod 61 so that the shoulder 67 retains the lever 53 out of locking position. Therefore, when the projection 57 again passes the lever 53, it will not engage the lever 53, permitting a second revolution of the roll 17. However, as the roll 17 approaches the completion of a second revolution, the cam 68 will have again engaged the shoulder 69, withdrawing the rod 61 and permitting the spring 63 to press the lever 53 again to locking position so that the shoulder 57 will come into engagement therewith and retain the mechanism locked until another coin has been deposited in the coin chute 52.

A lever 7 6 is also pivoted to the end of the roll 16 as by a pin 77. One end 78 of the lever 76 presses against the outer side of a roller or pin 79 carried by the strip 32 and extending through a, slot 81 in the end of the roll 16. The other end 82 of the lever 76 is so shaped that as the roll 16 approaches the completion of its revolution, the end 82 engages a pin 83 rigid with a portion 84 of the frame 8. However, the end 82 of the lever 76 is so proportioned that it will pass from engagement with the pin 83 at just the instant that the roll 17 has completed two revolutions, and the roll 16 has completed one revolutionJ It is obvious that at that time the groove 37 in the roll 17 will have again come into register with the knife 31 so that as the end 82 of the lever 76 passes from the pin 83, the strip 32 will be pressed outwards by the springs 35, so that the knife 31 enters the groove 37, severing asheet 84 of prede termined length from the end 23 of the paper which has'been unrolled from the roll 12. It should be called to attention however, that the end 82 of the lever 76, does not pass from the pin 83 until after the knife 31 and the slot 37 have passed the plane which includes both axes of rotation of the rolls 16 and 17 This is'an important feature, in that it insures the retention ofthe end 23 of the paper from the roll 12 after the sheet 84 has been severed therefrom, because the point of sevigsmgeer erance is slightly seda e-glint 01': tested of jthe two"rolls{withtheipaper Means are provided ferz mainglampem ing substantially" the center of" each of the sheets-to be severed and discharged from the device: 'Fhe' sheet of paper of which the roll 7 12:- is formedgis doubled longitudinally upon parts b and preferably serrated-' knife- 86 upon its surface, the" ends 87' and 880f which aredisposed adjacent that? end of thef'roll associated with the folded edge of the paper-.1 However, the end 88* is spaced slightly from that end' oftheriolli for a purpose to be hereins after disclose'di f A'compwmentarygroove 89 is formed in the surf ce of the roll? 1 7, the

Furthermore, since the end 88 of the knife 86 tially rectangular sheet having an opening. 7 substantially in the center thereof, this opening being defined by the cut 91 and having the tongue 96 which may be foldeddown- .wards from one side of the opening; This sheet is so shaped and proportioned that it is adapted to form a sanitarycoverfor' atoilet' seat, andthe tongue 96 afl'ordsadditional sanitaryprotection as it depends from the toilet bowl. a

front portionof the body of the sheet into the 'A guide 101 extends inwards from the housing'6 to guide the sheet-s84 through a 56 discharge opening 102, to facilitate thedischarge of the severed sheets after they have been released'by the cutting rollers 16 and-17;? Reversal of the direction of rotation of'the;

rolls 16 and17, is prevented by a' pawl 103 pivoted as by a pin 104 preferably tothe ba'ck 7. The pawl 103 hangs with a finger-at. its outer end 106 engaging the teeth of the gear 26 in such a mannerthatthe roll.16 may be rotated forwards butnot'b-ackwards.

The method of operation of the dispensing device of invention is subs'taiiliially'i'as follows-z v 1 When an attempt "is inade to min the the coin chute 5 2, the projection: 57 in engage.- ment withthef'1even 53 W-1ll prevent-rotation oft he' di'sc so thatbthe only rot ati'on tha-t handle- 47 without first depositinga coin in V can heeflected will' be that of tlie outer diso 46 which is permitt'ed -rotaiiy movement, the

fex'tent ofwhich is limited by the engagement 7 of the pin 48 withi'n the slot1 49. j However,

when a coin is'properly deposited and. then the-handle 47 rotated, the coin w'ill engage the 'lever 53 zbefore the projection '57 raising the l lever and permittingithe proj 'e'ction' to pass. 7 Thus the rolls maybe turned to "discharge a sheet 8'4: through the discharge opening 1.02,
