, DISPENSING MACHINE.
Application filed February This invention relates to machines for dispensing commodities, and in its present embodiment it is adapted todispense pieces of paper of a size suitable for use as towels, together with small pieces of paper coated with soap and suitable for use as a substitute for a cake of soap in washingones hands.
, Briefly, the-present embodiment of my invention comprises a cabinet or casing adapted to house a roll of towel paper and a roll of soap-coated paper, or soap paper, as I shall call it. Projecting from'thecasing is a shaft which carries a crankfor operating themachine. To operate the machine the user turns ;moves backward to the extent of the; fraction of a' revolutionit has been moved forward,
- and therefore the crank i'salways in the same position in'its circle of rotation at the beginning of an. operation or cycle of movement.
In' the preferred form'here shown the crank canonly be operated effectively after a coin has been deposited in a slot, but a modification of this arrangement is shown wherein the crank can be operated without the use of a coin. In either case the-crank encounters a.
positive stop when it has moved the requisite f distance forward and it cannot. be moved past this stop until afterit has been allowed to recede to its starting point. v I shall now proceed to describe my machine and its operation," referring tothe accompanying drawings, in which,
;Fig.1 is a perspective view of my machine, enclosed in its cabinet;
is a front elevational view Fig. 2 with the cabinet open 8,1926. Serial No. 86,743.

' F 12 shows the manner of notching the shear blade, so as to leave the strip of soap paper attached to the roll by a small unsevered section.
Referring now. to Fig. 2, a large roll of paper, 25, is mounted on a core or spool 26, this spool being revolubly supported at 21-27 by the walls of the cabinet- 28. Running downward from the roll 25, the paper passes over an idle roller 29, and thence around the propelling roller 30, against the lower side of which the paper is pressed by a spring actuated pressure roller 31, see Fig. 5, I
in which figure it will be seen that immediately after passing the bite of rollers 30 and 31 the paper, then marked 25T, passes across the top of the fixed shear blade 32. In front of this blade the bottom of the cabinet is out paper, andat-tached to'the lower edge of the front of the cabinet is an upwardly-inwardly extending guide 3-3 to deflect the paper and away to form an opening for the egress of the guide it downward should that be needed.
tical plates 40 and-4C1, the former being seen at the left and the latter at the right hand end of the rollers in Fig. 2. The axis of roller 30, in the form of a shaft 42 rigidly secured in the rollempasses through the plate l1 and carries a pinion 43, which lies close to the plate and is rigidly secured to the shaft. Beyond the pinion a sleeve 44 is secured to the shaft. Seealso Fig. 3. This sleeve serves as the propelling roller for the soap paper.
. The roll 50 of soap paper is mounted on a core or spool 51, which is revolubly supported at 52-52. Running downward from'the roll 50 the soap paper passes over the idle roller 53 and thence around the roller 44, against which it is pressed by a spring actuated pressure roller 54. See Fig. 3. After 7 passing the bite of rollers 44-54 the paper a revoluble shear blade 57, the cross-section passes between guides 55 and 56, whereby it is directed between the fixed shear blade 32 and the movable blade 57, the approximate path of the soap paper as it emerges from the opening in the bottombf the cabinet being indicated by a dotted line in Fig. 3.
Associated with the stationary blade 32 is of whichvisshown in Figs. 3 and 8. Referring to Fig. 2 it will be seen that this blade is of helical form, like the blade of a lawn mower, This helical form is also indicated in Fig. 9. The mounting for the left hand end of the blade 57 is shown in Fig. 5, where it is seen that the trunion 58 formed on the end "ofthe'blade is mounted in the lower end of an arm 59, the upper end of which arm is pivotally attached to the wall of the plate 40, a fragment of which plate is shown in Fig.
"5. In this figure the pivot carrying the arm 59 'is shown in section. The free end of the arm 59 is yieldingly pressed toward the stationary blade 32 by a spring 60, while the distance the spring can inove the arm is limited by a set screw 61. When the properadjust ment has been effected this set screw is locked bya nut 62 which is tightened by being tilted with a set screw 63. The right hand end of presently, a certain length of paper will be drawn from the roll 25 and delivered through the opening in the cabinet. Simultaneously a predetermined length of. paper will be removed frointhe roll 50 and delivered Obviously'the length of the paper 25T (Tmeaning towel) will be to the length of the paper 50S (S meaning soap), as the diameter of the roller'30 is to the diameter of the roller 44.
After the pinion 43 stops rotating the shear blade 57 begins to rock and it first shears the paper 508 from the roll '50 and it next shears the paper 25T from the roll 25. A small portion of the edge of the blade 57 is cut away at 64. This is best seen in Fig. 12. As this I mal'ly pressed against. the periphery of the figure is diagrammatic the spiral form of the blade is not indicated in-the fragment of the blade shown. It is obvious, however, that because of this notch 64 in the blade a short section of the paper 50S will remain unsevered, allowing the paper to hang by a corner as i Fig. 2, The user completes its detachment by a slight pull and thusits fall to the flooris avoided. By means which will be described presently the paper 25T is also left attached by a small section, by which it hangs, as in Fig.2, until detached by the user.
I shall now describe the mechanism for rotating the pinion 43. A horizontal operating shaft is journaled in the plates 41- and 71, which shaft extends through the right hand wall of the cabinet'and carries an operating crank 73. Contiguous to plate 41 a large gear wheel 74 is secured to this shaft. The teeth of this wheel are adapted to enmesh' with.
thoseof a pinion 75 which is revolubly mounted on the plate 41, this pinion being enmeshed fourth of the teeth of the gear 74 are cut off;
so that rotation ofthe pinion 75 by the gear is intermittent. To insure retention of the pinion 75 in a positionwhich will permit the entrance of the first tooth on gear 74 between two of its own teeth, a spring-actuated pawl" 76is provided. -This pawl locks the pinion against rotation,'and at about the moment the first tooth of gear 74 engages pinion 75,.a mu-' 'tilated ring 77 secured to one side of the mutilated gear 74 engages and lifts the pawlout of engagement with the pinion, thus freeing the pinion. The operation of the pawl is illustrated in Fig.4: Should it be necessary to rotate the roller 30 by hand the pawl 6 can be lifted by a pull on the hook 78.
'I shall now describe 'the mechanism for operating the shear blade 57. Loosely mounted on the shaft-'70 is a lever 80. This lever. is
connected by a link 81 to one end of alever 82 pivotally mounted on a stud 83 extending horizontally from thelplate. The other. end of lever 82 is connected by a link 84 to an arm 85 V which is secured to the shear blade 57. A spring 86, see Fig. 8, whose tension is exertlinks to retract the shear blade, i. e., open the shear, as in Figs. 2, 3 and 8; Movement of "11o ed on lever'82, moves this series of levers and this arrangementthe backward movement of the latter blade serves to sharpen it, on the principle that a lawnmower is sharpened by. backward rotation of the roll, as iswell; known. Movement of these parts in the op posite direction is arrested by thelever 85 impinging on the screw stud 87, as in Fig. 9.
Secured to the shaft 7 O is a disk 90, which carries a lug '91. A pawl 92, pivotally at-' tached to the free end of the lever 80, is nor- I disk 90, and when in this position the end of this pawl lies in'thepath ofthe lug 91,
and when the" crank is turned so as to rotate the disk 90 in the direction of the arrow drawn on the disk in Fig. 9 the lug 91 engages the end of the pawl 92 and rocks the 'lever to the position shown in Fig. 9, and
thus the shear is operated. By proper ad- 7 j ustment of the screw-stud 87 the shear blade 57 is arrested before the paper 25T is entirely severed from the roll, leaving the towel hanglng by one corner as 1n F 1g. 2. The
relative angular position on the shaft 70 off the gear 74 and the disk 90, is such that movement of the disk from the position it occupies in Fig. 8 to the position it occupies'in Fig. 9 occurs while the toothless portion of the gear 7 4 is passing the pinion 7 5. Therefore, the paper dispensing rollers 30 and 4A paper drawn from the rolls of paper previ oils to the operation of'the shears above described. I shall now describe mechanism for lifting thepawl 92 to let the lug 91 pass under it, so as to permit rotation of the crank one full revolution before it rotates the fraction of a revolution during which the shears are operated as described.
The disk 90 is provided with a pocket 1.00 adapted to receive a coin 101. This pocket is shown with dotted lines in Figs. 8 and 10.- See also Fig. 2. When the crankis turned after a coin has been deposited in this pocket through the slot 103, Fig. 1, the coin raises the pawl 92 sufficiently to let the lug 91 pass under the end of the pawl. See Fig. 10. By means of a screw 93 the radius of movement j of the lug 91 may be varied, so that a coin of predetermined diameter will be required to allow the lug to pass the pawl 92. As the disk rotates, the coin drops out of the pocket and into a coin box 102. See Fig. 1. Having turned the crank one revolution, wlnch brings the disk 90 to the position it occupies in Fig. 8, and during which revolution therequired length of towel and soap paper havingbeen drawn out of the cabinet, the opera tor continues turning the crank until it is arrested by the lever 85 impinging on the stop stud 87 Thus the crank is turned about one and one-fourth revolutions forward.
When the operator removes his hand fromthecrank the crank automatically recedes adistance equal to the fraction of a revolution it"has moved forward. The spring 86, acting through the lever82 and associated parts,
serves toturn the disk 90 a portion of this distance, that is, until the lever 80 is arrested by engaging the lever 82, as in Fig. 8, after which the recession of the crankis effected by a spring actuated arm 110, pivotally attached 11 i engaging the teeth of a ratchet wheel 115 carried by the shaft 70. A few teeth removed from this wheel permit the required backward movement. Mounted on the lever 80 is a pawl 116, which, when the parts are in their normal positions, as in Fig. 8, abuts the radial end of a notch 117, see Fig. 8, in a collar 118 secured to the shaft between the lever and disk 90. See Fig. 2. Should the shear blade 57 stick and fail to return it a mere safety device as the contingency it provides for is not liable to occur. Pivotally mounted on the disk is a coin ejector 120. See 10. This device is shown alone in Fig. 6. It has a finger 121 extending later- .ally from its free end and lying in curved slots 122 out in the walls of the coin pocket- 100. Mounted on the plate 71 is a stud 123,
and should the coin fail to drop out of the pocket it will be forced out by the finger 121 when the ejector encounters the stud 123 and is thereby rocked outward. Should a coin be dropped into the slot too small to unlock the crank, the coin can be removed with a small wire hook inserted in the slot 103 in the casing. Getting the hook under the nose 124: which projects from the ejector 120 the ejector can'be lifted and the coin with it. The lower portion of the slot 103 is broadened to provide room for the wire. See Fig. 1. A guard is provided to prevent the pawl 92 being lifted by a wire or the like in serted through the slot 103. In Figs. 9 and 10 it will be seen that the periphery of the disk 90 runs close to the guard leaving no space for any implement between the disk and guard. In order to provide for the lug 91 passing the guard and yet permit the extension of the lug beyond the periphery of the disk, a portion of the disk is reduced in diameter, this part being indicated by the numeral94 in Fig. 9.
. To convert the machine into a free dispenser the ejector 120 is removed from the disk 90 and in its place is put a cam 130. See Figs. 7 and 11, which has a lug 131 extending laterally from its free end. Then a deflector 132 is secured to the plate in the path of the lug 131. At the beginningof a cycle of op-- eration, that is, when the disk 90 is in the position it occupies in Fig. 8, the lug 131 lies on the top of this deflector, at a point near its upturned end 133. As the disk 90 is moved to the position it occupies in Fig. 11 the cam 130 raises the pawl 92 and this allows the lug 91 to pass the pawl. The disk is then free to rotate one revolution. At the end of this revolution, however, the lug 131 passes under the deflector 132; therefore the deflector does not lift the pawl 92. Therefore the lug 91 engages the pawl and rocks the lever 80 in themanner already described and operates the shear in the usual. way. The left hand end of the deflector is bent down at 134 to form a can be forced back by the crank. This is ramp, and as this ramp 134 is in the path of i the 111 131 the deflector is made flexible so the left hand end can yield to letthe. lug pass. But immediately after the lug has passed, the deflector springs back to its normal position, so when the disk returns the lug slides up the ramp and is then in position to lift the pawl 92when the crank is next r0- tated forward.
As a full roll of paper has considerable weight, to keep it from over-rotating and possibly disarranging the machine in case the crank isturned too rapidly, I provide a novel braking device. This comprises two arms 140, pivotally attached to the back of the cabinet and extending to the top of the roll.
The ends of these arms, which arms are preferably made of stiff wire, are bent toward each other and these opposed ends are united by a piece of tubing 141, slipped loosely on them. Secured to each of these arms is a fiat plate 142 adapted to lie against the end of the roll, and these plates are pressed against the roll by a spring 143 which draws the arms toward each other. The end of the roll of paper, passesover the tube 141 and pressing the tube down on the roll helps to retard the roll.
When the roll is reduced to the point where i the lower edges of the plates 142 rest on spool 26 the tube 141 is held off of the roll and the only friction remainingis that of 'the plates 142 against the ends of the roll. A similar ,arrangement is used on the roll 50 of soap paper.
An extended review of this invention is not necessary. As a vending device it has a large field in railway stations, libraries, theaters and other public places. As a free dispenser it also has a large field of usefulness. The
' use of soap coated paper in lieu of soap has certain obvious advantages in public or sein1- public places. Attempts at obtainingthese advantages by the use of liquid soap have not been altogether successful. Paper towels also arev highly desirable in public and semipublic places; they are a permanent institu tion. My machine offers a novel means for simultaneously dispensing a towel and a piece ofsoap-paper, or sheet soap, as it might properly becalled, and in that connectlon it offers certain novel and useful details, for example,
the slight attachment to therolls by which the towel and soap are supported until cletached by the user. Another novel and useful detail isthe fact that the towel and soap are delivered unfolded, saving the user the trouble of unfoldin the towel.
Having fully described my invention and its preferred embodiment, what I claim and desire to protect by a patent is as follows:
