PAPER-TOWEL-VENDING MACHINE.

Application filed J'uly 18, 1922- Serial No. 575,863.

To all whom it may concern: Be it known that I, EDGAR E. SHELLEY, a citizen of the United, States, and residing at Newark, inthe county of Essex and State of New Jersey, have invented certain new and useful Improvements in Paper-Towel-Vending Machines, of which the following is a specification, such as will enable those skilled in the art towhich it. appertains to make and use the same.

This invention relates to machines for vending paper towels, napkins and, the like, and particularly to machines of this class in which the towels .or napkins are manually removed or vended from the machine by graspinga projecting portion of the paper from which the towels or napkins are formed and pulling on said paper to actuate the mechanisms of the machine; and the object of the invention is to provide a machine of the class and for the purpose specified comprising a simple, positive and accurately operating mechanism for vending paper towels, napkins or the like; a further object being to provide an improved paper cutter or tearing device for severing the separate towels or napkins from a roll of paper, said cutter or tearing device cooperating with a paper feed drum, oran elongated aperture therein with means within the drum for controlling and regulating the operation thereof and with other means on the drum cooperating with said cutter device for controlling the operation thereof; and with these and other objectsin View the invention consists in a machine of the class and for the purpose specified which is simple in T construction, efficient in use and which is constructed and operated as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. .1 is a front view of my improved machine;

Fig. 2 a longitudinal sectional view through the machine with parts of the construction broken away and in section;

Fig. 3 a transverse sectional View through the machine, the section-being partially on the line 3-3 of Fig. 2;

Fig. 4- a partial transverse section on the line H of Fig. 2 with the parts in a different position; y

Fig. 5 a view similar to Fig. 1 but'showing the parts in a different position; and,

Fig. 6 a view similarto'Fig. 5 but showing the parts in a different position.

' My improved machine is what I call a free vending paper towel or napkin machine and, in practice, I provide a suitableboxshaped casing 10 which is closed at the sides, back, top and bottom, and the front of which is closed by 'adoor 11 adapted toswing upon atransverse rod 12 and held in a closed position by arod 13 passed through abeaded portion 14 at the top of the cover and through the sides of thecasing 10, said rod being provided with ahead 15 at one end and with acotter pin 16 passed through the other end thereof. The bottom of the casing'lO is bent upwardly as shown at 17 in Fig; 3 of the drawing to form adischarge aperture 18 through which thepaper 19 from a roll'20 is adapted. to pass.

The roll ofpaper 20 is'rnounted on'a heavy shaft orrod 21 which enters angularly arrangedguide channels 22 on the inner facesofthe side walls of the casing, as clearly shown in Figs. 2 and 3. of the drawing, and theroll 20 of paper is adapted to rest upon the top of afeed drum 23, the

periphery of which is provided with a rough facing 24, such as emery cloth or the like.

endswithrcap"members 25 and 26 of openwork or web-like structure'and having central bearings through which ashaft 27 is passed'an'd on which said drum is free to Thedrum 23 is hollow andprovided at its rotate. Theshaft 27 ismounted in aframe 10 comprising'V-shaped side members connected by threerods 10", and this frame fits Within thecasing 10 and is detachably mounted therein and is keyed in position byrecesses 10engaging projections 10? on-the inner faces of the sides of thecasing 10. Thedrum 23 is provided with anelongated aperture 28 at 'a predetermined point on the periphery thereof, the walls of said aperieo ture being. reinforced by metal facing sheets a plurality of projectingannular flange members 30 cut away at intervals .and provided where cut away with projectingpins 31. Ashaft 32 is mounted longitudinally of and in front of thedrum 23'and is rotatable in the sides of theframe 10*, said shaft being provided with acutterblade 33 having projectingteeth 34 and a central aperturedportion 35, as shown in Fig. 2 of the drawing, and secured to theshaft'32 atone end.

thereof is a Genevamember 36 having four substantially arc-shaped or]concave surfaces 37 adapted to operate inconnection with the arc-shaped flanges on themember 25 of the drum, and in the corner portions of the Geneva member are three elongated aper- .tnres38 in connection with which thepins 31 are adaptedto operate for intermittentlyopera-ting said Geneva member andthecutter blade 33. I

Pivotally mounted in connection with the inner faces of the'side w-alls'of thecasing 10 are twolever arms 39, the free ends of which carry atr'anverse roller 40* preferably composed ,of rubber, and this roller is adapted to bear on. the periphery of the drain-23 "in juxtaposition to theshaft 32, and aspring 41 rs mounted on theslraft 32 centrally thereof and cooperates with the 'r'oller 40-110 tensionally hold said roller in engagement with the drum. n V I Secured to theshaft 27 within thedrum 23 andin juxtapositionto the cap member :26'thereofis fa cam '42 and pivotally mounted inconnecti on with the-member 26 is alever 43, which carriesa-roller 44 which operates in connection withthecam 42, and aspiral spring 45 isc'onnected with the shaft of theroller 44 and with the drum as shown at 46 and serves-to normally hold the roller in engagement with the periphery of thecam 42 at .all times' Anotherlever 47 is pivoted to themember 26 asshow-n at 48 and is provided with a spring 49 for normally holding the same? inenga-gement with the free end of thelever 43, andsaid-lever 47 is provided with aprojection 50 adapted to engage a pin -51- .for intermittently ztripping said lever or moving the same out vof engagement with the-lever 43 -'as--her eina-fter setou't.

In the useof my improved machine, it will beapparent that theframe 10 with the 51m and the parts'of the f drum as well :as the shaft 32-and .its parts is set in the easing er in the lower=portion thereof, atter which-the roller 4O is placed in position and a roll ofpaper 20. mounted in the casing with the free end thereof fed between theroller 40 .and drum :23 and between theshaft 32 and ,said drum to the ,position shown .i;n 1lig. 3aof,the drawing, or .projecting' slightly through theaperture 18 "after whichthedoor 11 is closed in the manner hereinbefore set out. The machine isv now ready for use and by pulling downwardly on the protruding portion of thepaper 19, thedrum 23 will be rotated in the first step of this operation, as indicated in Fig. 4 of the drawing, in .which it will be noted that theshaft 32 has been turned one quarter revolution by the engagement of one of theapertures 38; of the Genevamember 36 with one of thepins 31, and it will also be noted that the-roller 44 on thelever 43 has been raised on thecam 42 against the tension of thespring 45 and thelever 47 has dropped beneath thelever 43 to take up the tension of the spring 45and'to permit of the free rotation of the drum by the paper. It being understood that the paper is under slight tensionin the first namedoperation, or in the first step of the operation of rotating the drum, the nexttwo steps is shown in Fig. 5 of the drawing in which the Geneva member has been turned two-quarter revolutions by engagingtwoaother pins 31 on said drum and the drum has been moved into position to bring theaperture 28 there- .ofin position to permit. of the passage .of thecutter blade 33 into the drum through said 3.5,

aperture, which operation cuts or tears thepaper 19 over said aperture and dissects .the same from the remainder of the paper,v ex- .cept wheretheaperture 35 is locatedin the cutter blade. v V

In Fig. 6 ofthe drawing, I have shown the beginning of the last movement of thedrum 23 and Genevamember 36 in which [the plain corner, or unapertured cornerof the Geneva member passes into one of the out away portions of the flangeBO, which is shown at 52" Fig. I 3 'of the drawing and permits of the movement of the Geneva member back into the position shown in Fig. 3 of the drawing, and this last named operation also extends the"eut edge of the paper into-the position shown in Fig. 3, it 'beingunderstoOd that thecam 42 androller 44 operate 'toproduce this result. In the beginning of the I'last named operation as 1 hown in Figs. 5 and 6 of the drawing, thelever 47 is moved out of engagement with 'thele ver 43 to permit of the quick descent of said'lever on the cam, or the face of thecam 42 to impart a sudden rotary movement to-the drnni, while thecutter blade 33 ,passes nto and out of the aperture28:of thedrum. It will also be apparent that onewall of theaper'tu're of the drum aids in moving the 'cutter blade out of the :aperture 28 and in turning the Geneva member.

The above description completes one cycle of the operation of the machine, andfit will be understood that. every, timethe projectingport'ion of the paper19 'is pulled through the machine, .a predetermined portion thereof will be cutoff :for use, andthe recess 53 in the 'face of the 035 .42 w ll operate to retain theroller 44 therein to hold the drumagainst movement, after the completion of one cycle of operation, it being understood that a decided pull is required on the paper in order to raise the roller over the cam face from the position shown in Fig. 3 to that shown in Fig. 4. p i By providing atransparent panel 54 centrally of thecover member 11 the condition of theinachine may be seen at all times and the time for replacing a new roll of paper determined Without I opening thedoor 11. lt will also'be apparent that by providing the frame 1O as a unit for supporting the (111111123 andthe severalparts mounted in connection therewith, as Well as theshaft 32 and its-parts, the operative mechanisni'ot the machine may quickly and easily be placed in position in thecasing 10 or re moved therefrom for repair orother purposesfand While- I have shown certain de tails of construction for carrying my invention into effect, ltWill be understood that I am not necessarily limited to these details, and various changes therein and modifications thereof may be made, Within the scope of the appended claims, Without departing from the spirit of my invention or sacrificing its advantages. i i
