The seat cover shown in Fig. 1 has a V-shaped lower edge indicated at a, a, and a similarly shaped upper edge a, a. It is also .provided with a partially severed, centrally located flap b, the unsevered portion 0 being near the lower or front end of the toilet seatcover.

The towel shown in Fig. 2 has the same- V- shaped ends but no flap. 1

These articles are adapted to be made from a web of paper w, the web roll being indicated at W. This web is passed betweencooperative male and female rollers 39 and 40, the roller 39 being one-half the diameter of the roller 40. They are driven in unison by gearing to be described.

The developed surface of the smaller roller 39 is shown in Fig. 3. It has helical slots 42a and 42b arranged for cutting the V-shaped ends a, a

of the toilet seat cover. It also has grooves indicated at 43a, 43b, 43c, 4311,43; disposed about the surface of the cylinder for forming the flap 1). This flap, as indicated in Fig. 1, is an oval flap secured to the body of the seat cover at c. As the length of the flap is more than one-half the length of the seat cover, the grooves 43d and 43e cross the grooves 43b, as indicated in Fig. 3.

The male roller 40 has outwardly projecting *end forming knives 44 of V-shape adapted to enter the grooves 42a, 42b. These knives are preferably designed so as to incompletely sever the web, as set forth in the patents above referred to. The male roller also carries the flap The developed shape of this knife is the same-as that of the flap b to be formed in the seat cover. Itis adapted to. mesh with the grooves 43a, 43b, 43c, 43d, and 43a of the female or grooved roller.

The frame of the machine includes vertical side frame members 50' and 5|, top and bottom cross members 52 and 53,and a tie rod 54'. The side members 50 and 5| are flanged-at the rear as indicated at 50a and 5|a, and slotted as indicated at 55 to facilitate mounting the frame on headed members 56 secured to the rear wall of a case, indicated at 5'1. The front of the case is indicated at 58, this case being adapted to completely enclose the machine.

The web roll W is supported in bearings 59 secured to the side frame members 50 and 5|, and spring pressed friction arms 60 bear on the core ends 6| to resist unwinding of the paper. The web is passeddownwardly about a guide roller 62, which appliesit to the surface of the grooved or female roller 39 near the top of this roller. The paper is then passed about the surface of the female roller 39 and between this roller and pressure rollers indicated at 63. These "rollers aredrivingly connected by gears indicated at 64 and 65. The paper is fed downwardly by a delivery roller indicated at 66.

The paper delivery mechanism associated with these delivery and pressure rollers, forms the subject matter of my copending application for patent on Paper delivery mechanism executed concurrently herewith, Serial No. 703,099, filed December 19, 1933.

A side plate 6! is secured to the right hand frame member 5|. This side plate revolvably supportsthe shaft portion 68 of a crank 69, and gears 10 and II. The gear 16 is in mesh with a gear 12 carried by the crank shaft and secured to the female roller to revolve therewith. The end plate 6'! also provides the bearings for the rollers indicated at 63 and 66. A somewhat similar end plate at the other end of the machine provides the bearings for the female roller and the two rollers 63 and 66. This plate does not appear in the section shown in Fig. 4.

The male roller 40 is mounted on a shaft 13 revolvably carried on the lower end 14 of hanger members 15. The upper ends of these hanger members are pivoted on studs 16 carried by frame plates 50 and 5|. The male cylinder shaft 13 also carries a gear 11 in mesh with the gear II. The gears 12, 10, H, and 11 act as a gear train to revolve the shaft 13 at one-half the speed of the female roller 39.

A form of stop and release mechanism is shown in Figs. 5 and 6. The crank 69 supports a locking lug 18 which in turn revolvably supports a disc 19.

This disc has a limited movement by reason of the pin and slot connection indicated at and 8 I. It has a laterally bent ear indicated at 82 and is notched in front of this ear, as indicated at 83-.

It is urged clockwise by a coiled spring 84' interconnecting the lug I8 and disc 19.

A selector lever 85 is mounted to rock about the crank 68- and is held in the position indicated in Fig. 5 by a coiled spring 86. This lever has a notch indicated at 81 and laterally extending flanges 88' and 89. The notch 81 is adapted to receive the nose 90 of a stop lever 9| pivoted at 92 and urged counter-clockwise by a spring 93. The upper left end of this lever has a shoulder 94 which is adapted to engage a shoulder 95 of the locking lug 18 and the lateral extension 82 of the disc 19.

When the parts are in the full line position of Fig. 5, turning the hand crank clockwise is prevented. Should one raise or lower the selector lever 85 it will be rocked about the axis of the crank and one or the other of the flanges 88 or 89 will engage the nose 90 of the stop lever 9|, thereby shifting it to the position indicated in Fig. 6. This brings the shoulder 94 above the lateral extension 82 on disc 19 and allows the spring 84 to shift this disc on the locking lug so that the edge of the disc passes under the shoulder or'abutment 94 as indicated in Fig. 6. The selector lever may now be released and it will return to the full line position of Fig. 5. Stop lever 9|, however, is held against movement and the crank may now be turned in a clockwise direction to effect two revolutions of the female roller and one revolution of the male roller.

The selector lever is provided with a rearwardly extending finger 96 adapted to engage the front end 91 of a latch lever 98 secure to a shaft 99. The latch lever 98 is notched as indicated at I09 to receive a lug |6| carried by-the hanger member 15 and is urged downwardly by a coiled spring I02. The other end of the latch lever shaft 99 is connected to a latch lever 98 similar to the latch lever '98 and cooperating with a lug |0| similar to the formlthe V-shapecl end. This operation takes place irrespective of whether: or not the male l04 on the cutter hangersthen engage bumpers I05 ca'rriedby the-frames.

The male roller 40 is provided with cams I06 and Illl. These cams are engageablewith rollers I08 and I09 carried by the frame plates and, as

shown in dot and dash lines inFig. 6, these cams are broughtagainst theserollers during the latter part of the revolution of the male cylinder. The cams operate to press the male cylinder forward or to the left, as indicated in Figs. 5 and 6, bringing the roller axis'back to the front position and causing the latches 90 and 918 to engage the lugs I01 and'IIlI". and holdthe male cylinder in the forward position.

- This operationisbrought about before the end severing knives M arriveat thecorresponding groovesin'the female roller and hence each time themachine is operated the end forming knives are in position to function "to s'ever the paper to roller has been in the front or rear position during the initial part of the cycle. When the male roller is in thefront position, theflap forming knives enter the corresponding grooves and form the flap, and when in the rear position they fail to enterand hence a towel is formed without a The cam I66 engageslthe'lower end 9Ia of the stop lever III during thetime when the notch 83 on the disc "I9 is opposite} the abutment 94 of the I stop lever, and'acts to hold the stop lever in the I full line positionof Fig. 6, so that it does not interfere with the continued rotation of the crank. This permits two revolutions of the female roller to take'placebefore thestop mechanism functions to stop the machine. l-Iolding the selector shownin Fig. 1.

lever up or down allows one to make a number of seatco-vers or towels withoutstopping the machine. I I

In Figs. Ste 12, inclusive, the female roller is indicated at I10 and the male roller at III. The female roller has grooves similar to the grooves shown in Fig. 3. 'Iwo of these grooves appear'in the cross section of Fig. 12 and are indicated at IIIlwand IIfib. The maleroller has end forming knives IIZand fiap forming knives I I3." These knives are of the proper outline to mesh with the grooves and form the seat cover similar to that Owing to the fact that the structure shown in Figs. 9/00 12, inclusive; contemplates that the axis of the male roller shall be manually set to place to make either seat covers or towels, and remain j in this set positionuntilchanged, the knives II3 for making the flap are shorter than the'knives longer knives II2-,'are made Wider to H2 for cutting the endsof the towels or seat covers and the grooves IIIla, whichreceive the accommodate the extra length knives. C

When the male roller is in the position indicated .in full lines in Fig. 12, the knives H2 and I I3 both enterthe proper grooves, but when the male roller is moved to the right as indicated in dot and dash lines in Fig. 12, the flap severing knives II3 fail to reach the grooves. The knives II2, however, are longer and reach the corresponding grooves.

The male roller III is provided with end discs I I4 having hubs I I5 bored to receive circular discs.

H6. These discs are eccentrically keyed to a shaft Ill. The shaft II? is mounted in fixed bearings I I8 in the frames H9. The shaft III is connected by an arm I with a link I2I, which in turn is connected with a lever I22 pivoted at I23. This lever extends forwardly, as indicated at I24, and may be raised or lowered so as to oscillate the shaft I ll. Turning this shaft back and forth effects a movement of the male cylinder toward or away fr'omthe female cylinder.

Owing to the use of two eccentrics carried in fixed bearings and operating on opposite ends of avoided. I

The drive between the male and female cylin ders is in the form of a sprocket chain I25 which passes about sprocket wheels I26 and I2'I carried by the female cylinder and male cylinder. The chain also drives the pressure roller I28 and passes about an idler I29. This idler is carried on a .the male roll, parallelism of shaft axis is main- I tamed, and weaving about on the supports 20 bell crank I30 pivoted to the frame of the ma- I chine and having a lower end I3! having bifurcations I3I and I3I"which embrace the hub II5 of the cylinder end H4. When the arm I22 is turned as indicated in Fig. 9, the bell crank I 32 is shifted so as to shift the idler I29 and keep the chain tight.

The stop and release mechanism of Figs. 9

and 11 has a bifurcated arm I 32-pivoted at I 33 and shiftable back and forth by a plunger I30.

.The full line positions indicate the positions of this lever at .theend of a cycle. The shaft I33 carries an arm I movable back and forth with the bifurcated arm I32 disposed inside the frame member H9. The endof this arm I35 is adapted to engage a stop lug I36, carried by the end II of the male roller to stop the machine at the end of a cycle.

When one desires to release the machine for operation, the plunger I34 is pressed inwardly. This shifts the bifurcated arm I32 and thelever I35 to the dot and dashline position of Fig. 11, thereby moving the end oflever I35 away from stop lug I36 and carrying the upper inner bifurcation I3I of the lever I 32 away from the pin I38 which is connected with the hand crank As the crank is rection, it completes approximately one-half a revolution when the pin I33 engages the left bifurcation I40 of the arm I32. At about the same time the lever I35 engages with a camming element I4I carried by the end of the male cylinder.

The turning of the crank then continues until the pin I 38 is brought to the-position indicated at I38a, Fig. 11. It then engages with a toothlike element I42 carried by the bifurcated lever I32 and turns it and moves the lever I32 further to the left, bringing it to the full line position of Fig. 9 and Fig. 11. The camming element Uh; may, at about this time, engage the lever I35 so thatthe same movement may be effected by such an engagement. The machine is stopped when the stop lugI36 engages the lever I35 or when the pin I38 engages the end of the bifurcation I Iil. A spring pressed pawl Hi4 overlies the pin I33 when the machine is in-the stop position and prevents backward turning.

then turned in a clockwise di- The chain drive mechanism of Fig. 9 is a method of driving the rollers generally alternative to the gear arrangement of Figs. 5 and 6. Gears may be used with the eccentric shifting mechanism or chains with the latch and spring shifting mechanism.

In the arrangement shown in Figs. 13-17, inclusive, the flap forming knives are collapsed relative to the end forming knives when one desires to avoid forming a flap. The female roller is shown at 200 and the male roller at 20 I. The female roller is provided with flap forming grooves 202 and end forming grooves 203 similar to the corresponding grooves shown in Fig. 3. The male roller has an end forming knife 204 similar to the end forming knife 44 of Fig. 4. The flap forming knives are indicated at 205a and 2052), these knives being in two parts to permit collapsing.

The female roller 200 is connected with a gear .206 which is in mesh with a driving gear 20'! carried by the male roller. The male roller has a disc 203 at the right side connected to the gear 201. and a disc 209 at the left, the male knife being fastened to these two discs as indicated at 210, Fig. 15. The male knife is also secured to a central assemblage 2! I by screws as indicated at 2I2 (Figure 16), this central assemblage acting to support the collapsible knives in a manner to be described.

The central assemblage 2II employs two castings 2I3 and 2M secured together by bolts indicated at 2I5. The casting-2B is secured to a shaft 2 I6 by a locking screw 2. This shaft H6 is secured to the left disc 209 and projects beyond, as indicated at 2I8, to form a bearing for the left end of the male roller.

The right hand disc 208 is secured to a sleeve 2 I 9 by a clamping screw 220, so that this sleeve is driven by the revolving of the gear 207. This sleeve extends to the right, as indicated at 210',

to form a bearing in the right hand frame 22! of the machine. The left end 2 I9 of the sleeve 2 l 9 extends into the casting 2 I4 and is secured to it by a clamping screw 222. It also receives the reduced end portion 223 of the shaft 2 It.

It will thus be seen that the central assemblage 2 is securely mounted on the two part shaft formed by the shaft 2I6 and the sleeve 2E9, and that the end discs and central assemblage, together with the end severing knife, will revolve as a unit.

The control for the knife collapsing mechanism is manual- A shaft 224 projects forwardly out of the cabinet in which the machine is mounted, and is provided with a selector arm or crank, indi cated at 225. This shaft is revolvably mounted in an extension 226 carried by the frame member 22! and is provided with an off-center pin 227 which enters a slot 228 in a link 229 pivoted at 230. Shifting the hand crank 225 from the full line position of Figs. 14 and 15 to the dotted line position'will shift the lever 229, as indicated in Fig. 15. An over-the-center spring 23I may be employed to insure that the parts will stay in the position to which they have been shifted.

The lower end of the lever 229 is bifurcated as indicated at 232 and receives a disc 233, mounted on the end of a shaft 234, carried inside the tube 2I9, so that the shaft is reciprocated back and forth by manipulation of the crank 225. The inner or left end 235 of the shaft 234 is connected to a pin 236 which extends out through slots 23? in the sleeve 2 I 9, and which is secured to an outer sleeve 238 slidable along the inner sleeve 2 I 0. The sleeve 238 is secured to a strip 239 of arcuate crosssection, whichextends through slots 240 and MI in the castings 2 I3 and 2 I4, whereby this arcuate shaped member may be guided for reciprocation and held against rotation. The reciprocatory member 239 is provided with a helical slot 242 into which projects a pin 243 carried on a sleeve 244 revolvably mounted on the reduced end 223 of the shaft 2I6. Sleeve 244 is adjacent the casting 2 I4, and through the helical slot and pin arrangement is adapted to oscillate back and forth when the selector handle 225 is shifted, as shown in dot and dash lines in Fig. 16.

The sleeve 244 is connected by three pins 245 with another sleeve 244 adjacent the casting 2 I3. These two sleeves are revolvable on the reduced end 223 of the shaft 2 I6. The pins 245 carry radially extending links 240, 24! and 248. The link 248, as shown in Fig. 14a is connected by a pivot pin 249 with a hinge casting 250 which is secured to the male knife part 205a. The link 246 is similarly connected by a pin 25I and hinge casting 252 with the portion 2052) of the flap forming knife.

The adjacent portions of the flap forming knives 205a and 20512 are secured to hinge members 253 and 254 by rivets indicated at 255 and 256. These hinge parts are in turn mounted on a hinge pin 251, secured to the outer end of the link 24! and guided in slots 258 in radially extending portions 259 of the castings 2 I 3 and 2 I4. The flap forming knives 205a and 20% are cut away as indicated in Fig. 13 to accommodate the portions of the castings just referred to, so that the male knives may be drawn inwardly, as indicated in Figs. 16 and 17. These projecting portions 259 form guides for the male severing knives during collapsing and provide a connection which drives the knives during rotation.

It will be obvious that when the flap forming knives are collapsed, as indicated in the dot and dash lines of Fig. 16, that they will not reach the grooves in the female roller and hence no flap will be formed. The paper will be passed through the machine in the usual manner to form a towel without a flap. It will also be obvious that the shifting can take place at any time and that a selection need be made only when a change in the product of the machine is desired.

In the form of construction shown in Figs. 18-24, inclusive, the collapsing of the flap forming knives is accomplished by the oscillation of a shaft carried axially with respect to the male roller axis, the inner end of the shaft being connected to flap forming mechanism somewhat like that which has been described in connection with Figs. 13-17.

In Figs. l8-2 i, inclusive, the female or grooved roller is indicated at .300 and the male roller at 30 I. The female roller may be made the same as previously described. The male roller has an end disc 302 on the right and a somewhat similar end disc on the left, not shown,the right hand disc being secured to a sleeve or tube 303, and the left hand disc, not shown, being secured to a shaft 304, indicated in Fig. 25. These discs are secured to the sleeve or shaft by clamping screws such as indicated at 305. The sleeve 303 and shaft 304 are mounted in bearings in the main frame 306. The end severing knife 301 is similar to the end severing knife 204. The male and female rollers are driven by gears indicated at 308 and 309 having a 1 to 2 relation.

The selector lever for determining whether or not the machine is to make seat covers or towels is indicated at 3I0. It is pivoted at 3II on the to receive a shaft 3!5 carried in. the sleeve 333.

The shaft 3I5 is secured to a disc '3I6 slottedas indicated at 3!! to receive a pin 3I8 carriedby revolution relative to the male roller,or tothe dot and dash line positionof Fig. 18, which is the same as thefull line position of Fig. 22.

V Thispartial revolution of the shaft 315 effects the collapsing of the flap forming knives; as will now be described.

. The central. assemblage 326, as show n in Figs.

24 and2 5, employs two castings 32!. and 322 similar to the castings 2! and 2 M. Thecasting 3221s secured to the sleeve 383 by ascrew. indicated at 323. and the casting. 32!. is secured to the shaft 364 by ascrew indicated at 324. The two castings. are secured togetherby bolts indicated at 325. The central assembly issecured to the middleof the end forming knife 36'! by screws 325a, hence the central assemblage and shafts and end forming knife revolve as a unit. The inner end of the shaft 3l5 is connected with a collar 326-similar to ,the sleeve 243. .This collar 326 carries three pins 32'! which are secured to a disc 328. The pins 32'! carrylinks 329, .336, and 33! which are similar to the arms or links 246, 24! and 248. Theyare connected with flap forming knives 332a and 332bby hinge sponds with thehinge pin25l of Figs. 16 and 17 and slides in and outin a slot 338 similar to the slot 258. The disc 328 carries an arm 339 which is connectedwith a spring 348 anchored on a post! carried by the casting 32!. This spring acts as an over-the-center spring to hold the. shaft 3l5 in theposition to which it hasbeen shifted. 7 I j Should one desire to restore the flap forming knives to operative position, the selector 3! 6 is returned to the full line position of Fig. 18. the

Acoin chute is indicated at 356. A plunger 35 projects forwardly of the machine and is, provided with a coin receptable 352. p The sides of the coin receptacle are slotted as indicated at 353 to receive a pin 354 on' which is mounted a link 355. The other end of this link is connected bypin 356 with a lever 35'! pivoted at 358 3 to the frame of the machine.

When the parts are in the full line position as shown in Figs. 18, 2 1 and23, an extension 359 on the lever 35'! is in the path of a pin 366 carried by the end disc. 362 of the male roller and prevent s further rotation ofthdmaleand female rollers. If a coin C is placed in a chute it comes between the pin 354 and the abutment 36!, so

that pressure on the plunger 35! will push the arm 355 to the right, thereby passing the extension 359 inside the'pin 363. This releases the rollers and brings the right hand end 362 of the plunger to the dot and dash lineposition of Figs. 7

i the path of a lug 363 carried by the vertically movable member 3|3, so that the selector 3"] cannot be shifted up or down after the coin has beeninserted and the rollers released. The lever 351 is restored to the stop position by a'cam 364 carried by the end disc 302, so that it will bein the path of the pin 366 to stopthemachine at the end of the cycle. The cam 364 is annular except for. the depressed portion indicated at 364w which acts to restore the plunger 35! and arm 35]. i l

p The cam 364 is provided with two notches 365 and366, seeFig. 20. The notch 3651s inline with fiange361 carried-on a vertically guided member 368, this member being connected to the selector lever 3w by a link 369. When the selector lever is in the full line position the flange 33'! is.

above the level of. the cam364, as is clear from Figs. 18, 19 and 21,, and when the selector is in the dot anddash line position, the fiange 36! is belowthe level of the cam 364. The cut out portion; 366 ofthe cam 364 permits the ,male cylinder to "revolve when the vertical movable member 368 is in the lower position.

The arrangement just described requiresthat the machine be in the stop position and that the release mechanism be still acting to prevent operation of the machine before one can actuate the After the turning of the machine is started, the selectorlevercannot shifted. This makes it impossible to get the pin 3l8 and slot 3 out of time during thenormal-operation of the The .only way in which this can be done is by manually turning the disc 3 !6 or collapsing the knives insonie improper manner, but as the machine is enclosed in a casing, itis inaccessible for such tampering.
