16 Claims.

This invention is of the same general character and form and is for the same purpose as the invention disclosed in Letters Patent No. 1,913,- 722, granted to me on June 13, 1933, but embodies several major and minor improvements which will appear'as the description of the present invention progresses.

Briefly, this invention contemplates the provision of a simple, efficient and durable mechal0 nism including a suitable case arranged to rotatably and detachably support a roll of towel paper in such a manner in the case that substitution of inferior or the other grades or'kinds of paper may not ordinarily be made without detection or tampering with the mechanism, thereby insuring uniformity of quality of the paper used in the dispenser.

Another. object is to provide accurate means for gripping, measuring and dispensing uniform sections of towel paper and including a couple of dispensing rollers at least one of which is rotated independently of the paper roll and to exactly the same extent in all dispensing operations, together with means associated therewith and under manual control for releasing and instituting movement of the dispensing rolls and automatically operable for stopping the operation thereof when a predetermined length of paper has been dispensed for use.

Other objects include: the provision of means to prevent the backward rotation of the paper roll when the mechanism is at rest; means for accurately centering the paper in the case and the prevention of longitudinal movement of the paper roll, and still other features which I will describe hereinafter.

In the accompanying drawings I have shown a preferred form of mechanism for the purpose described, subject however, to modification within the scope of the appended claims without departing from the spirit of my invention.

In said drawings:

Fig. 1 is a front elevation of the assembled dispenser partly broken in section so as to show the operating elements of the mechanism;

Fig. 2 is a sectional elevation of the same on line 2-2 of Fig. 1;

Fig. 3 is a sectional elevation on line 33 of Fig. 1;

Fig. 4 is a fragmentary section on line 4--4 of Fig. 3, showing a detent associated with one of the paper dispensing gears;

Fig. 5 is a sectional elevation on line 5-5 of Fig. 1;

5 Fig. 6 is a sectional plan on line 6-6 of Fig. 3;

Fig. 7 is a sectional elevation on line 1-1 of Fig. 1;

Fig. 8 is a fragmentary section of the operating means on line 88 of Fig. 7.

My dispensing means includes a two piece case 5 comprising a case C and a cover C hinged together at the front of the case as by means of a pair of hinges I, I. Said hinges are attached to the lower edge portion of the front Wall 2 of member C and to the bottom 3 of member C. 10 It will be observed that member C has

parallel ends

4 and 5 and a back 6, while member C has ends 1 and B and the front wall 2 is continued upwardly and backwardly over the edges of the

ends

4 and 5 of member C so as to completely l5 enclose the mechanism within the case. Ends 1 and 8 of member C' overlie the

ends

4 and 5 of member C, respectively. Member C may be suitably secured to member C as by means of a latch 9 adapted to engage a member 10 attached to the 20 back 60f member C.

Thus, the case C is open at the top and front so as to permit the ready attachmeiitor removal of a roll of towel paper R.

At longitudinally opposite positions on the case 25 C supporting members I i and I2 of difierent form are permanently secured to the

ends

4 and 5, respectively. Member i2. has laterally formed flanges I4, M, which are suitably affixed to the end 5, and a wall i3 spacedirom end 5 of case 30 C. Said member also has a semi-circular bearing portion I5 at the bottom of a slot i6 which is open at its upper end for receiving a trunnion l1 carried by the paper roll R at one of its ends.

It will be noted that the bearing I5 is of but 35 the thickness of the metal plate of which the member I2 is formed and said bearing is in a plane but slightly spaced from the plane of its associated flange, thereby providing a recess i8 between the bearing and the inner side of the 46 end 5. Member H, however, is diiierently formed, of spring wire and is provided with a V shaped bearing portion IS, the apex of which is axially alined with the roll R, and has upper and

lower end portions

20 and 2! which overlie 45 the outer side of end 4 of case C. The lower end 2! is fixedly held by means of a plate 22 attached to the end of case C. The portion 19 of member ii is threaded through

slots

23, 23 above and below a rib 24 so as to prevent the complete 50 retraction of said member.

The paper rolls R are usually formed with a stifi hollow paper core 25, in one end of which I provide a metal trunnion I! which serves to rotatably support the paper roll R on the member l2. Said trunnion is of cup form with a cylindrical portion 26 adapted to be frictionally or otherwise held in the core 25 and has a flange 21 at its outer and open end, as shown in Fig. 1.

At the junction of the cylindrical body portion 26 with the flange 21 a slightly enlarged annular portion 21' may be provided for rotatably engaging the semi-circular bearing l5. When the trunnion is thus positioned in the supporting member i2 the flange 21 thereof will rest in the recess I8 at the rear of the bearing i5, thereby preventing the longitudinal movement of the roll R. Member ii is so formed and tensioned that the portion l9 will engage the adjacent end of core 25 and thus support the roll R detachably in the case. The roll R is inserted by moving it downwardly so that member I! will rest in bearing I5 and the member II will yield and finally seat the portion I9 thereof in the end of core 25.

In the front portion and at the bottom of the case member C I provide a couple of

parallel dispensing rollers

28 and 29 by means of and be tween which the paper P from the roll R is adapted to be dispensed in uniform lengths at each operation of the machine. Said rollers are preferably made of wood but may be formed of other suitable material. Roller 28 is rotatably supported on the

ends

4 and 5 of case C by means of trunnions 39 which are firmly held in and extend from the opposite ends thereof and through suitable perforations in theends of the case 0. Said roller 28 is of uniform diameter throughout its length and is adapted to receive and grip the paper P from the roll R, as shown in Fig. 5.

Roller 29 is yieldably mounted relative to roller 28 and has trunnions 3| which extend through slots 32 in the

ends

4 and 5 of the case and are rwiiiently connected with the trunnions 38 of roller 28-by means of

tension springs

33, 33. Roller 29 has a central section 34 which engages the paper P and reduced

end sections

35, 35, and said central section 34 serves to centralize the paper P in the case and to prevent the edges thereof from creeping longitudinally on the

rollers

28 and 29.

Roller 28 has a ferrule 36 at one end tightly pressed on to a slightly reduced end portion thereof, to which is suitably attached a pinion 31. Said pinion operatively engages a spur gear 38 which is fixed to an operating spindle 39 formed on or attached to an operating crank 40. Said spindle is journaled in the end 5 of the case C and carries externally of the end 5 a combined cam and locking member 4i which cooperates with a control lever 42 pivotaliy held at 43 on the end 5 of the case and adapted to be manually operated for releasing the spindle 39 for rotation, but is automatically effective for stopping the rotation thereof when a predetermined length of paper has been dispensed from the roll R.

Member 4| is generally circular in configuration but has a projecting lug 44 on the periphery thereof which is engageable with a lug 45 on member 42, as shown in Fig. 7, for stopping the rotation of the spindle 39 and associated parts at the conclusion of a dispensing operation. Member 42 has a handle 46 which, when the mechanism is at rest, normally occupies a position as shown in full lines in Fig. 7 and is operable manually by elevating the handle to the position shown in broken lines in Fig. 7, for moving the lug 45 out of the path of lug 44 on member 4|. Thereafter, as handle 49 is rotated in a clockwise direction, as shown in Fig. 7, the lug 44 thereon will engage a second lug 41 on lever 42,. after lug 44 has cleared lug 45, and cause a retraction of lever 42 to normal position with the edge of lug 45 engaging the concentric portion of the periphery of member 4! and in readiness to engage and stop the further rotation of the handle 48 and the

dispensing rollers

28 and 29.

The sections of paper P dispensed from the machine are preferably of greater length than width, and the length of said sections is determined by the ratio of

gears

31 and 38. As shown herein, gear 38 makes one complete revolution at each operation of the machine while gear 31 may make two or more revolutions, depending upon the diameter of roller 28 and the gear ratio between the operating spindle and said roller. In all cases, however, roller 28 is rotated to exactly the same extent at each operation of the machine and consequently measures and dispenses uniform lengths of paper P in successive operations. It will be noted that in this ma-- chine, the operating member being attached to the dispensing means, the gradually decreasing size of the roll R does not correspondingly vary the length of the paper section dispensed therefrom, as in other machines.

The end of the paper from the roll R is preferably loosened from the roll and moved back and under the roll over roller 28 and thence between the

rollers

28 and 29, and downwardly through an elongated aperture 48 in the bottom of the case C. Preferably the material cut away from the bottom of the case C to form the aperture 48 is bent downwardly on an incline, as shown in Fig. 5, .to form a cutting blade 49 having a serrated cutting edge. (See Fig. 1.) It should be noted that portions of the bottom 3 are bent upwardly to define fingers 49 as shown in Figs. 1 and 5. These fingers engage in grooves 35 formed at the junctures of

sections

34 and 35 of the roller 29, the sides and ends of said fingers being in substantial engagement with or lying close to the walls of said grooves. This arrangement prevents the paper from creeping under the rollers and insures a direct feed of paper from between the

rollers

28 and 29 out through the aperture 48.

When the paper is thus threaded between th

rollers

28 and 29 the roll R is prevented from backward rotation by means of a detent 50 which is pivotaliy held at El on the end 5 of case C and engages the teeth of gear 38 at its free end, as shown in Fig. 3. Detent 58 has a pair of

friction plates

52, 52 attached thereto and overlying the sides of gear 38, for the dislodgment of the detent and for other purposes which appear hereinafter.

In operation, a roll R of paper carrying the trunnion l'l at one of its ends is inserted in the open case by moving the same downwardly until the annular portion 21' of the trunnion seats in the bearing l5 and the opposite end of the roll.

Immediately after the disengagement of lugs 44 7 and 45, the lug 44 on member 4| will engage lug member I I is such that said member may not 41 on member 42 and retract lug 44 into the path of lug 45, so that it will be impossible to rotate the crank 40 more than a single revolution at ment as shown in Fig. l and applies friction on the end of core 25, is to remove the possibility ,of the paper creeping as it is unwound from the roll.
