The present invention relates to machines formaking and vending or Adispensing toilet seat covers and the like.

The present invention contemplates an improved machine for this purpose wherein all the parts are designed and arranged for easy `assembly in a small cabinet adapted to hold a supplv of tissue in the form of a roll, and to form and dispense the toilet seat covers ready for. use. The seat cover, or other paper arformed out of the web by cooperative vmale and female rolls v bearinga predetermined design. These rolls provide a machine for are preferablyarranged for tearing the paper along the 'desired lines by a sharp knife.

An 'object of thev present invention is to this purpose wherein the moving parts are all carried on two frame lmembers which can be assembled into a cabinet, the cabinet formingv the support for the frame members and holding the parts in f position.

. and

The invention relates to a machine for forming articlesfrom the entire width of a web of paper and 'dispensing the same, the articles being formed having severed ends oblique to the edge of the web, the machine being so designed that the web of paper passes ybetween male and female rolls which are out of contact except for the cooperative knives grooves provided to sever the paper, the tension necessary forl drawing the paper between these rolls being provided by a driven .pressure roller which is spaced sufficiently close to the plane offsevering of the male and female rolls to engage with the advancing edge ,of the web before the preceding article has been completely severed. In this way a pulling effort is always applied to' the web to draw it between the male and female rolls even though they Aare out of contact.

Ay further obj ect of the invention is to providea paper straightening devicey such as a s iral roller for stretching or straighteningv the paper soy as to `prevent the formation of longitudinal creases as machine;

it passes through ythe A further object of the invention is to royvide guidingand pressure rollers for holy ing instead of cutting it the paper on the female roll, both these rollers being spring-pressed toward the female roll, the pressure roller being preferably geardriven.

A further object of the invention is to provide an improved arrangement forv supporting the vpaper roll while the paper is being threaded into the machine.

A further object of the invention is to provide an improved means for stopping the seat-forming mechanism at the end of a cycle, and to provide coin control mechanism.

Other and further objects of the invention will appear as the description proceeds.

Thecover y17 may then This cai'- ries the roll up to the position indicated in full lines in Figs. l and 5 without disturbing the paper which'has been previously fed through between the iolls. The paper rides against springs 64a and 64b carried in the inside of theV cover. These springs keep the paper away from the front of the box and produce acfriction drag against the paper sufficient to keep it taut during severing and prevent overrun when the machine is stopped at the end of the seat cover forming operation.

It will be noted that the female roll is smooth, except for the grooves or slots 42 and 48 which receive the edges 37 of the flap forming knife andthe edges 84 and 85 of the end forming knives, and that these edges'project outwardly from supporting parts which are well within the pitch circle of the gear 48 and hence that there is no rolling Contact of the male and female rolls whereby the paper may be drawn off the supply roll against the friction drag set up between the paper roll and the stationary members 64a and 64b. Owing to the absence of rolling contact between Athe male and female rolls ordinarily employed in paper handling machinery, it is necessary to arrange other means for imposing a pull on the paper at all times when withdrawal of the paper is to be accomplished.

Figure 7 shows in full lines the edges of a web' of paper, a completely formed seat cover,

(suspended), and the initial cut made for forming the flap of the next succeeding seat cover. The heavy lines CP and PP indicate the cut-olf plane and pressure plane,

respectively, at the end of the cycle, and their spacing indicates'the arc between these male roll.

planes, measured on the surface of the fe- The dotted lines op and pp at the top of the figure, together with the dotted representation of a seat cover, show' these planes just before the completion of the formation. of thev seat cover. The oblique lines for the ends of the seat cover intersect the lines op and pp and hence a portion of the web, stillconnected with the supply roll, is carried beyond the cutting plane and under the pressure roll so as to be available for pulling the paper ofi' the supply roll. It is thus important that` the angle on the female roll occupied by the cutolf grooves should exceed the angular spacing of the planes of severing and pressure application. I

jIn order that the machine may make a single seat cover and then automatically stop, it is provided with an automatic stop mechanism indicated at 65 which functions to stop the machine when a seat cover has been completed and is iii position to be taken from the machine. lVhen the machine is designed for dispensing toilet seat covers, this release mechanism 65 may be manually actuated to release the seat-forming mechanism and automatically actuated to stop the machine. In the present case, however, the machine shown is designed for vending, and the release of the automatic stop 65 is by a coin control mechanism to be described.

- A coin may be inserted through a hole in the upper front part of the cover and passes downwardly and rearwardly in a chute 71 cairicd by the hinged cover 17.

This chute deliveis the coin in-o a vertical chute 72 secured to the rear wall. of the cabinet l0 by bolts indicated at 7 This coin chute may be formed of sheet metal and is arranged to allow the coin to drop into the bottom of the cabinet. downwardly through the chute, it strikes a rear finger 7 4i forming part of a bifurcated spring pressed trigger member 75.

This trigger member is pivoted at 76 on the coin chute 72 and the upper end is urged forwardly by a leaf spring 77. The front bifurcation of` the' trigger member is indicated at 78. It is provided with a shoulder or notch 79 adapted to receive a rearwardly extending arm 80 of the stop mechanism.

The passing of the coin past the trigger mechanism swings the trigger clock-wise as viewed in Fig. 4 and releases a spring-pressed member 80 from the notch 79 causing it to swing in a clock-wise direction under the instop the seat-forming mechanism, the mutil' lated shaft 83 is in such a position that the upper front corner 85 of the same will engage with a pin 86 carried by the gear wheel 48 to thereby arrest the seat-forming mechanism. When, however, the trigger mechanism 74 is actuated by the coin, the spring 8l acts to shift the mutilated shaft from the full'line position, Fig. 6, to the dotted line position. This moves the upper shoulder 85 far enough in a counter-clock-wise direction, as appears in Fig. 6, to permit the pin 83 to pass by. This pin then passes beyond the mutilated shaft and engages with a resetting cam 87 carried thereby so'that the mutilated shaft and arm 80 are moved back up so as to i As the coin passes reset the trigger mechanism. The .seat-form-l 'f ing mechanism' is fthen ,carried through thejcycle and'` is stopped at the .proper time. e

89. andlocked by a lock 90.

lVhen one desires to test' the seat-.forming mechanism Without employingza coin, alsmall instrument may be passed into the coin controllerd mechanism to pressl back the upper Y I y y I v male andfemale rolls, a pressure roll on the .end75 ofy the trigger. w y

Atthe end of the seat cover forming operation, the paper has beenl carried forward* yuntil the line .20v p indicates the approxiniateposition. of. the line of pressure on thel next partially'iormedseat cover, The nevvly Jiiormed seat cover hangs downwardly asin,-
