DISPENSING-CABINET FOR TOILET PURPOSES.

Application led January 15, 1915.

T 0 all 'whom it may concern Be it known that I. FRANK W. CALVERT, a citizen of the United States, and resident of Narberth, county of Montgomery, State of Pennsylvania, have invented an Improvement in Dispensing-Cabinets for Toilet Purposes, of which the following is a specification.

This invention has reference to a new and useful improvement in dispensing cabinets for paper for toilet or towel purposes. and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

My inventionv has for an object to provide a cabinet for packages of folded sheets arranged in superposed relation and wherein the sheets are fed by gravity to a position adjacent the discharge opening and under the control of retarding devices for relieving the weight of the package upon the bottom sheet to thus reduce friction to a minimum during the withdrawal of a sheet.

The invention has for a further object to provide a device for automatically locking the package against movement in a direction reverse to the normal feeding direction whereby the iackage cannot be reached and manipulated y way of the discharge'opening in such a manner that the entire package or any portion thereof might otherwise be surreptitiously removed.

My invention has for a further object to provide a .mechanical means for ejecting from the cabinet the depending tab of the bottom sheetof a package and causing it to protrude in an accessible manner so that the sheet of that tab maybe manually drawn out of the cabinet.

Another object of the invention is to provide mechanical discharging means having interchangeable parts sothat the cabinet may be readily adapted for ejection of a tab where the cabinet per se is arran ed for different modifications of the type o package which presents tabs to be pulled in extracting a sheet. An object of the invention is also to provide a means for locking the mechanical discharging devices to the cabinet in such a manner that the fastening or locking devices are-normally concealed within the cabinet or the attached part and therefore may not be tampered with or removed by unauthorized persons.

Specification of Letters Patent.

' nected to sai Patented Dec. 14, 1915.

Serial No. 2,332.

An object of the invention is further to provide a mechanical discharging means operating in conjunction with a paper dispensing cabinet wherein one sheet or towel may have its tab brought into grasping osition by manual operation of the mechanical dis-I charging means, and whereby the towel may be fully removed thereafter by manually pulling upon the tab.

Another object of the invention is to pro vide a coin controlled mechanism for use in conjunction with a paper dispensing cabinet wherein a definite number of sheets may b e automatically fed to an accessible position by the insertion of a single coin and further this number cannot be varied or effected by the failure of a user to withdraw less than the required number.

My invention consists of organized mechanism for accomplishing the several objects above stated, and more` particularly described hereinafter and defined in the claims.

Referring to the drawings: Figure 1 represents a sectional elevation of the lower portion of a paper dispensing cabinet emodying features of my invention and showing a manuall operable ejecting device concabinet; Fi 2 represents a front elevation in section o a portion of the device shown in Fig. 1; Fig. 3 represents a sectional elevation of the lower portion of the cabinet anda coin controlled dispensing device connected thereto; Fig. 4 represents a section on line 4-4 of Fig. 5; Fig. 5 represents a plan of the coin controlled mechanism removed from the cabinet; Fig. 6 represents a section on line 6-6 of Fig. 5; Fig. 7 represents a section on line 7--7 of Fig. 5; Fig. 8 represents a detail showing the operative position of a coin with respect to the control mechanism; Fi 9, represents a modified form of controln device.

Similar numerals of re erence indicate corresponding parts.

1 designates the casing of a cabinet for containing and supporting in operative condition a package of folded sheets, such as' paper towels, each arranged to provide a tab by which each sheet may be drawn from the bottom of the package and removed for use. The sheets, in the present instance, are designed for use as paper towels and are packed in folded condition one upon the other within the cabinet -to form a complete, unitary package with the tabs of each sheet held folded between the abutting sheets and with the lowermost sheet having its tab depending through the opening 2 in the bottom of the casing 1. This opening 2 is formed by a downwardly inclined ledge 3 at one side and an upwardly inclined shelf 4 at the yopposite side, these partsbeing suitably spaced apart as will be underptood, to permit the tab 5 to assume its operative protruding position.

In connection with the cabinet construction it will be noted that I have provided a plurality of laterally disposed projections 6 positioned at intervals along a wall of the casing and preferably formed by pressing the metal or material of the casing inwardly so that the said projections are situated in the path of movement of the package. These projections serve as retarding devices to distribute the weight of the package and prevent the entire weight being concentrated upon the bottom sheet which rests upon the bottom supports of the cabinet. In cases where the package is supported directly upon the bottom members of the cabinet it has been found that the weight of the package is sutiicient to cause so much friction as to materially interfere with the free withdrawal of the bottom sheet and fre-v quently result in tearingr of the sheet. By providing the aforesaid retarding devices 6 the package is supported at a number of points throughout its length, but in view of the fact that these devices 6 are preferably small and may be also rounded as shown. they do not interfere with the free downward feeding of the paper.

7 designates a follower loosely mounted within the cabinet and preferably of a width slightly greater than the width of the interior of the cabinet so that its operative position is substantially inclined as shown 1n Fig. 1. Une end of this follower is preferably angularly arranged as shown at 8 and rests at one end against the side frame 9 of the door of the cabinet. while its opposite end is preferably of bifurcated formation in order to straddle the rear inwardly projecting wall of the cabinet with its ends 10 arranged in opposed relation to suitable teeth 11 formed in the cabinet. The teeth are preferably arranged in vertical rows. the comstruction being such to permit the follower 7 to slide freely over them during the downward movement of the package, but to prevent the follower from moving upwardly should pressure be brought. to bear upon the bottom of the paper pacha ge. This affords a means for positively locking the package agains.A upward movement and effectually prevents improper manipulation of the paper package such as inserting theJ hand through the discharge opening and removing part or all of the package.

In order to provide for the mechanical dispensing of the successive sheets, and tl'i'iis economically control the number which may be delivered to a user, I have provided a manually operable device, as one form of the invention, which is adapted to dispense one sheet of the package at a time, and as another form of the invention I have provided an automatic coin controlled device for dispensing successively ay number of sheets according to requirements.

In Figs. 1 and 2 I have illustrated one form of mechanical dispensing means wherein 12 designates a receptacle for inclosing the operating mechanism and having its top side partially or completely open, as the case may be, to form communication with the bottom part of the casing 1.

The receptacle 12 is preferably removably secured to the cabinet casing 1. but in its attached position the construction is such that it can only be removed by first emptying the cabinet of its contents. This result is effected by providing` the receptacle with a pair of projecting clips or hook members 13 located respectively at opposite sides of one end of the receptacle and` adapted for insertion between the bottom walls of the cabinet to engage the respective ledges 14 provided on the cabinet for that purpose. The receptacle is then fastened at its rear end byrneans of the brackets 15 which extend into abutting relation with screw or bolt seats 16, preferably pressed from the naterial of the shelf 4, so that the said parts may be secured together by the screws 17 or like fastening means.

18 designates a rock spindle located adjacent the front of the receptacle and extending longitudinally thereof, said spindle being journaled in the walls of the receptacle in a suitable manner. Upon the spindle 18 an ejecting device or finger 19 is mounted to turn therewith. the outer free end of which is adapted during the rocking of the spindle 18 to describe an arc which brings the ejector to the rear of the depending tab 5 so that the continued movement of the ejector forces the latter through the discharge opening formed by the rounded or beaded edge 'of the ledge 3 and the similarly rounded edge 20 upon the front wall of the receptacle. The ejecting finger preferably consists of a plate of relatively stiff material of a length substantially the same as the width of the sheet. so that the tab is pressed uniforrr-ly by the contacting edge of the finger.

21 designates an operating handle or crank fixed to the spindle 18 and having a suitable lug 22 provided for engagement with a stop or buffer Q3 which supports the ejector in normal position 24 designates a suitable torsion spring coiled about the spindle 18 and having its ends properly fixed in order that the spindle 18 may be automatically returned to its normal position after an operating movement of the handle 21.. From the foregoing it will be apparent that each rocking movement of the spindle 18 within the required limits will cause the ejector 19 to engage with a tab of the bottom sheet and force it to a protruding position where it may be grasped and the entire sheet manually removed.

25 designates a'I receptacle adapted to be secured to the bottom of the cabinet casing l in the same manner as described for the receptacle 12, though in this instancethe box 25 is of somewhat larger dimensions in order to contain an automatic mechanism for operating the ejector and also to provide a suitable space for a coin receptacle. The two receptacles 12 and 25 are therefore interchangeable and either may be readily attached to the cabinet in place of the other accordino` to requirements. The coin box is indicateda at 26, being supported upon suitable guide parts 27 and removable through an opening in the wall of the box 25. Normall the coin receptacle is locked within the ox 25, as will be understood, by any suitable means to prevent the contents being removed by unauthorized parties,

- In view of the fact that theejector, the spindle and torsional return sprin therefor are practically identical with the dike parts in the manually controlled ejector 'ust described, I have for convenience app ied the same reference numerals thereto. v

In the coin controlled device the rock spindle 18 is operated through the medium of an intermittent gear 28 fixed thereon and driven at required intervals b an intermittent gear 29, the teeth of which are preferably diametrically arranged for the urpose of causing two rock movements of t e spindle 18 for one revolution of the shaft 30 upon which the gear 29 is fixed. In order to maintain the two gears normally out of mesh and also insure their return to this relation after an operation of the ejector, 4I have preferably provided a cam 31 having two opposite portions thereof substantially concentric to the shaft 30 and the remaining oposed portions concave as shown at 32 to orm seats fora roller 33. The roller 33 is suitably mounted upon a movable arm 34 whichnormally holds the rollerag'ainst the outer surface of the cam by means of the spring 35. This construction affords a positive and reliable means for disengagin the gear teeth after a driving movement an the releasing action is instantaneously affected 66 Fig. 7 while it is held aganstrotation in since the roller 33 is forcibly snapped into the adjacent seat 32 through the action of the spring 35.

The rotation qf the intermittent gearl 29 is in the direction indicated by the arrow in the opposite direction by means of-a pawl 36 pivotally mounted upon the box and having one end 37 extended to contact with a fixed part of the box in normal osition, while the opposite cnd 38 is positioned in the path of movement of the gear 29. It is evident from this construction that the gear 29 may freely pass the pawl 36 since the latshaft 18 are entirely disconnectedfrom the driving mechanism and are thus free to be thrown back to normal inoperative position by means of the torsion spring 24. Sincethe ejector returns very quickliy and with considerable force to its norma position, I have provided a suitable bumper orA buffer 39 located at a convenient point to receive the iinact and prevent undue wear of the parts.

he coin controlled mechanism by which the required rotation of the operating shaft 30 is obtained consists of a hand lever 40 projecting through a suitable'opening 41 in the front of the receptacle and secured to an arm 42 which is freely mounted for. rocking motion u on the fixed stud or pin 43, the'said parts ingy maintained in normal aosition, with the handle at the upper end o the `slot 41 as shown in Fig. 4, by means of a torsion sprin 14 havin one end secured to the stud 43 an its oppositel end secured to the arm l2.

45 designates a gear secured tofthe arm 42 and rotatable upon the pin 43 to form a ratchet under the control of the. pawl 46.

this latter being pivoted to the farm 42 and held in operative position by the spring 41'. The gear 45 is arranged also to` drive a pinion ,48 fixed to the shaft 30 and by which movement of the arm 4D is transmitted tothe shaft 30, the relation preferably beingsuch that one operative stroke. of the handle 40 causes the shaft 3 0 to make one half of a revolution in order to operateA the ejector so that -the tab of one towel lor sheetismoved to projecting position. The mechanism by which the coin controls the actuation of the shaft 30 consists, inthe present instance, of a disk 49 fixed to rotate with the shaft 30 and provided with a cam projection 50having. adjacent thereto a notch 51. The cam projection 50 in normal position of the parts' contact with a lockin lever 52-which for convenience is freely pivoted upon the shaft 18 but is normally held in bearing engagement with the periphery of the disk 49 through' the action of the spring'. 53. This lever 52 has a, tooth 54 adapted to engage the notch 51 in the disk 49 at such-times as iso iii)

the disk 49 is rotated to remove the cam .projection 50 `from its holding position and when no coin has been inserted. In other words, the mechanism is always unlocked and the insertion of a coin merely serves to prevent the operation of the locking mechanism such as to permit the coin to drop freely past the shaft into theT position indicated in full lines in'Fig. 8, but when the disk 49 is rotated the coin is moved upwardly bya carrier, to be presently explained, untilit reaches the position indiated in dotted lines where it bears against the shaft 30 and prevents the lever 52 from moving to its locking position. The coin, therefore, serves the same function as the cam projection and prevents movement of the lever 52. It will therefore be apparent, whenever a coin is in the position indicated in Fig. 8, that the handle or operating lever 40 may be moved to cause the proper rotating movement of the shaft 30 -without interference from the locking lever 52.

57 designates a carrier suitably fixed to a side face of the disk 49 and moving in the plane of the coin 56 so that the latter is picked up at .the proper time and carried over the shaft to be discharged intothe coin chute 58 which discharges the coin into the bo'x 26. A

"59 designates the coin slide by which the coin is introduced into the machine, and from which itis discharged to fall to `the position indicatedin Fig. 8. In case a slug or coin of vdifferent dimensions is dropped icto'the machine it fails to enter the proper part of the mechanism and drops through opening 60, provided for the purpose, .upon the guide member 61 which directs it the discharge opening 62 in the bottom of the receptacle. In the preferred embodiment of 'the invention all ofthe Working parts are iai-losed by a suitable case 63 whereby they are protected from dust and dirt and also from unauthorized tampering.

in order to prevent tampering with the fastening devices for securing the detach` abile receptacles to the cabinet, I have pror' ed a 'device consisting of a plate 65 adaptto seat upon the y'Shelf 4 and extend above l; of the brackets 15, and thus normally meal the fastening Vcfa bracket' 66 toy one wall devices or screws 17. plate is heldin its operative position by of the receptacle and located above the coin box 26. This bracket is apertured to receive a fastening bolt or screw 67 which is inserted from beneath the bracket and has threaded engagement with a boss upon the plate and which extends through a suitable aperture in the,shelf. It will, therefore, be apparent that when the coin box 26 is locked in position within the receptacle it will efiectually conceal the head of the fastening device and pre-vent the latter from being operated to remove thev plate and thus expose the fastening screws 17. In this manner the receptacle, when once secured in position to the cabinet can only be removed by those having the proper key to unlock the coin box, as will be understood.

In the operation of the device, it is assumed that the parts are in normal position, such as indicated in Fig. 7, lwhile a tab of the lowermost sheet is suspended across the opening 64 and in the path of movement of the ejector 19. chute 59 falls to the position indicated in Fig. 8, where it acts, upon movement of the disk 49, as a wedge or separator to maintain the locking bar 52 in its normal or unlocked position. The downward operation of the handle 40 causes the pinion 48 to rotate the shaft '30, thereby turning the disk 49 so that the cam projection 50 is removed from engagement with the locking lever 52. This movement also brings the notch 51 beyond the point where it may be engaged by the tooth 54 so that continued rotary movement of the disk 49 is possible after the coin' is picked up, since the locking lever 52 now merely rides upon the periphery of the said disk. As soon as this position is assured the coin pick-up 57 engages the coin and forces it A coin dropped into the` to ride upwardly over the shaft 30 to a point where gravity causes it to drop into the chute 58. During this movement of the shaft 30, which represents substantially a quarter turn, the intermittent gear 29 has advanced to meshing position with the gear 28 and during the next quarter .turn of the shaft 30 this gear 28 causes the shaft 18 to rock and throw the ejector to the position indicated in Fig. 3 so that the tab protrudes through the provided opening and the sheet I by the locking device. Consequently the operating handle 40 and its adj uncts are free to be again manipulated. The second downward movement of the handle therefore results in the intermittent gear 29 again making a half revolution and operating the ejector for the V*second time.l In this connection it will be noted that after the ejector has delivered the tab of the rst sheet,the cam 31 will have n moved so that one of the concave seats iS beneath the roll 33 and the latter therevresult is' made possible owin upon snaps into place to quickly remove the teeth offthe gear 29 from the path of the teeth on the gear 28 so that the latter returns (under the-action of the torsion spring 24) toits former position simultaneously with the return 'of the` ejector.v It will be .noted that while I have referred to the movementof the handle 40 as a complete downward movement, this is not essential owing to the fact `that the ratchet connection of the hau- .dle with the operative mechanism provides a'means whereby the handle 40 may be reciprocated'a number of times without making a fullfstroke, and yet produce the same operation vofthe shaft 30 and its parts.

In operating the machine lit will be underlStood that as soon' as a tab of the sheet is Aprojected through the .discharge opening 1t is grasped a'nd the entire sheet removed before the operating handle is again manipulated to repeat the operation.

Incase a user of the machine should manipulate the handle but once and be satisfedk to obtain butA one sheet or towel it will be evident that the next user may either obtainl one towel without inserting a coin,

by inserting a coin and operating the handle three times lobtain three towels. This to the fact that the first user has turne the disk 49 through but one half a revolution and consequently the coin-pick-up 57 does not engage the coininserted by the ,Second user until it has completed its revolution to eject the second towel for which the machine has been set by the irstcoin. The second coin, therefore, remains in the position indicated in Fig. 8, holding the locking lever 52yfout of lockingv position until the coin pick-up has removed the coin, when of lever is prevented 51 owing to its engement with the periphery of the disk 49. Ifile two towels or sheets provided by this second coin will therefore be removed as usual. It will furthermore be seen, since the handle operating member controls a ratchet device, that the operation of the course the said locking vmechanism is `not eected byA the handle slipping from theY graps of the user and returning to its normal position.

In view of the fact that thel coin slide is preferably merely an open trough, the fact that several coins may be inserted in the machine at the same time does not aiiect its operation since only one can fall to proper controlling position, while the remaining. coin drops through the provided opening 60-as will be' understood. Furthermore it is impossible for the' same coin to operate the machine a vsecond time since the construction of the coin pick-up 57 is such as to positively carry the coin to the required point where it falls into the coin chute. Attcntion is also directed to the coin engaging parts 55 and 56X of the latch 52 since the one piece construction makes it a very easy matter to tit the parts for the desired coin.

While I have preferably referred to a coin as the lock releasing device, I Wish it understood that the invention is not to be restricted to such controlling means, since, for example, a mechanism ofthe type shown in Fig. 9 may be utilized for a like purpose. In this modified construction the locking lever 52 is provided' with an extension 68 projecting exterior of the casing into a position where it may be readilyl manipulated to Cause the machine to operate in the desired manner. This is accomplished by holding the lever in its normal position so that the locking lever is prevented from moving to its locking position after the cam projection has been removed by a turning movement of the shaft 30. After Lthe disk 49 has been moved to a position where' the lockin lever tooth can no longer engage the notc it will be understood Athat the extension or controlling means for 'the locking lever may be released and the device operate as hereinbefore described.

I desire to note that the terms upward, downward, inward, outward and ,movable are all relative, and are used without limiting significance, although in the device as here shown the operating handle has a rocking movement in a vertical plane about a vertical axis and the ejector is movable up and down in an arc about a horizontal axis, yet I desire it understood that Ido not limit the invention to a mechanism in which the parts are so arranged. Consequently the above terms, and also such terms as above and below, used throughout the specification and in the claims to describe the relation and movement of one part with respect to another, are to be considered as relative and not as limiting the invention to the particular 'construction shown.

It will now be apparent that I havesdcvised a novel and useful construction which embodies the features of advantage enumerated as desirable, a d while I have in the, present instance shown and described the preferred embodiment thereof which has been found in practice to 'give satisfactory and reliable results, it, is to be understood that I do not restrict myself tothe details, as the same are susceptible of modification in various particulars without4 departing from the spirit or scope of the invention.
