COIN-OPERATED VENDING-MACHINE.

Specification of Letters Patent.

Patented Aug.-9, 1910.

Application filed ma 'is, 1909. Serial No. 495,801.

T 0 all whom 'it may concern:

Be it known that I, HARRY R. CANFIELD, a citizen ofthe United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Coin- Operated Vending-Machines, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to what are known as coin operated vending machines; and the object thereof is to provide an improved machine of this class particularly designed for use in hotels, cafs, saloons and other public places for vending paper or fibrous towels; a further object being to provide a machine of the class specified particularly designed for use in vending paper or fibrous towels from a roll of material mounted in a suit- I, able casing and from which at each operation of the machine a predetemiined length or strip of the material is fed from the roll and may be detached for use as a towel.

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 Figure 1 is a side view of my improved vending machine, Fig. 2 a front view thereof, Fig. 3 a sectional side View of the machineasshown in Fig. 1, Fig. 4 asectional front view of the machine as shown in Fig, 2, Fig. 5 a sectional view approximatelyflop the line 55 of Fig. 4, Fig. 6 an apprentmate section on the line 6-(5 of Fig. 4, Fig." 7 a transverse section of two feed rollers which form a part of my improved machine,

Fig. 8 a loi'igitudinal sectional viewof said rollers, and ;Fig. 9 a face view or side view of a strip of towel material after it is passed between thefecd rollers. In the practice of my invention, I provide a main casing (4 having a back a w iich, in the form of construction shown, is provided at the top and bottom thereof with projecting members a by means of which the machine may be secured to a wall or other shitable support, and the back of the casing a is provided at its opposite sides with or- .wardly directed pedestals w, a and a, and

left hand side as shown in the drawings, are hinged to the. back a as shown at a, and the hinged pedestals a, 0i and a 'fit in corresponding aperturesin the left hand side a of the casing a, and the pedestal a on the right hand side of the casing a also fits in the corresponding aperture in the right hand side a of the casing a all as clearly shown in Fig. 4, rind the pedestals a and a in the right hand side portion of the casing a are inclosed by a supplemental casing or laterally directed extension at at the bottom of and on the right hand side of the. main casing a.

In Fig. 6 I have shown the method of hinging the pedestals a a and a at the left hand sideof th main casing a, the pedestal a being shownfin Fig. 6, and said pedestals are hinged to the back a of the main casing a and are provided with slotted feet a through which are passed bolts o provided The left hand side a of the main casing a, the right hand side a, the top a, the bottom a, the front a and the supplemental casing 'or extension a at the right hand side of the main casing a are all formed integrally, and are rigidly connected with the back a of the main casing a by means of projecting cars a" at the top a and bottom HARRY R. CANFIELD, OF NEW YORK, N. Y., ASSIGNOR TO NICHOLAS J. SAVAGE, 0F

1 NEWARK, NEW JERSEY a which are. rigidly secured to the project ing members a of the back (L The back a of the supplemental casin a which is formed integrally with the bacl a of the main casing a is provided with a pedestal a which fits in the corresponding recess in the outer side wall a of the supplemental casing a as clearly shown in Fig. 4 and as iartially shown in Fi 3.

- From t is description, it wil? be seen, that the casing of my improved machine consists of a main part and a supplemental part, the

back of both parts being the same and the sides, front, top and bottom of both parts being formed lntegrally andbeing detachably connected with the back part, but my.

these pedestals at one side of the casing, the l invention is not limited to any particular means for connecting said parts of the easmg of the machine, nor other features thereof as described.

Mounted in the top portion of the main part of the casing, and in the oppositely arranged pedestals a thereof is a roller b on which is wound a strip or sheetb of paper from' which towels are formed as hereinafter described. Below the roller 12 aret'wo main feed rollers c and d which also serve. as

cutters for perforatingor partially dividing the strip 6 at regular intervals, and' these rollers are also corrugated diagonally'or otherwise-as indicated at c andd in Figs. 1 and 7 for the purpose'of crimping, crap- .ing or otherwise forming the strip 1) into such shape or manner as toadapt' it to serve more conveniently and readily for thepurpose intended, or as towels. The rollers c and d are of predetermined dimensions and designed at each complete revolution to feed a predeterminedlen th, say from fifteen to eighteen inches, of t e strip Z) through the front of the main easing at a, at eacli complete revolution of said rollers, and said rollers are also provided; one with a longitudinal row of suitably formed recesses 0 and the other with a longitudinal row of suitably formed teeth or projections d which, at each complete revolution of said rollers,

I will form in the strip or sheet Z1 a trans- .verse row of apertures b as clearly shown in Fig. 9, said apertures beingseparated by narrow longitudinal strips or connecting members 5*, and at each complete revolution of the rolle'rs 0 and (Z in the operation of the machine as hereinafter described apart or section of the strip or sheet' I) is fed forward through a transverse aperture a .in the front a of the mam easing a, and in this operation the transverse apertures 1n the strip or sheet I) are fed forward to the point,

. b in Fig. 3, at. which point. the transverse pressions, and in the construction shown,

these teeth or projections not only serve to crimp or crape or break the'si'irface of the aper, strip or sheet I)", but also serve as inter-meshing gear teeth for the said rollers, and by means of which one of said rollers is turned by the other, in the operation of the machine as hereinafter described.

The object of'hinging the pedestals a, a and a on the left hand side of the cashw (a as shown at a in Fig. G'and as above cescribed, is to facilitate the mounting of or removal of the rollers b, 0 and d; and the -obj-'ectof providing pedestal bearings for these rollers independent of the cover of the machine is'to provide a construction whereby the machine may be opened up for inspection without disturbing any of the operating 'part s thereof.

The roll'is 0 and a? are secured to their shafts respect-iv ly by a key and key way construction well known andplainly shown in connection with the roller 0 at c" in Fig. (3, and by means of "this construction, in mounting the rollers upon the shafts, the key isthst inserted in the key way of the roller and the roller and its key then passed pedestal a? being fii'st moved outwardly as shown in dotted lines in Fig. 6 to'permit of this operation. V

Rigidly secured to the shaft 0'' of the roller 0 is a crank disk 0, and lateral motion of this disk is prevented by the pedestal a as plainly shown in Fig. 4; the disk 0 is-provided with a wrist pin 6 rigidly secured is a spiral spring 6'' ranging vertical therefromand which is secured at its lower end to a post 0 rigidly secured to and extending forwardly from the back a of the machine as shown in Fig. 6 and-indicated in Fig. 5. The wrist pin (2 is also rigidly connected to a ratchet disk 0 provided at its center'with a bearing adapted to operate in connection with the end of a shaft 0 to be described later. The spring a operates to normally hold the disk 0 and the ratchet disk 0 in the positions shown in Fig.5. The ratchet disk carries a spring pawl c shown in Fig. 3.

Operating in the pedestal a is a shaft (2 provided at its outer end with a crank c rigidly secured thereto, and inwardly of the pedestal a is a driving disk 6 also rigidly secured to the shaft e.and the shaft (2 extends through the driving disk 6 inwardly thereof and occupies the bearing of [the ratchet disk a as plainly shown in Fig. 4. As will be seen, the pedestal (4 supports the and ratchet disk 0 are supported by the pedestal a and the shaft 6. Secured to the cover of the machine and extending rearwardly into the supolemental casing a is a vertically arranged partition e plainly shown in Fig. 5 which follows approximately the contour of the'ratcliet' disk 6 to the bottom portion thereof from which it extends horizontally to the baclaa of the tion is bent away at its upper end from the righthand face of the ratchet d sk 6 and the partition e is provided with a segmately the contour of the ratchet disk 0 exover the shaft a as will'be understood, thethereto. and operatingupon the wrist pin a crank e and drivingdisk e and the disk c mental rib c at right angles to the part-L- tion 0" and'which also follows approxh machine, and as shown in Fig. 4 this partithe ratchet isk c and held normally thereon by a spring 6 also. pivoted to the partition 6 at e, and this pawl prevents-rotation of the ratchet disk 6 in a direction opposite to the arrow a: shown in Fig. 5.

As shown in Fig. 4, the ratchet disk 0 and the driving disk e are soniounted as to have a space between their adjacent faces, and extending downwardly into this siace and formed integrally with the cover 0' the ma chine is a fingers, the shape of which is shown in Fig. 5.

The driving disk 6? is provided as shown in Fig. 6 with a tooth e" which operates-in connection with the spring pawl e on the ratchet disk 6 to prevent the independent rotation of the driving disk e in a direction oppos te to the arrow 3/ in Fig. 6 will be understood, and the tooth e" is indicated in dotted lines in Fig.5.

The ratchet disk 0 and the driving disk are provided with coin recesses c and 0 respectively which are similar in contour as shown in dotted lines in Fig. 4, and of the transverse shape shown in Fig. (3, and these recesses extend radially into their respective disks.

Mounted in the top portion of the supplemental c'nsing a. is a coin chute of which communicates with a corresponding slot 11. in the top portion of the supplemental casing a as shown in Figs. 4 and 5.

In the lower part of the supplemental casing o, and between the side wall 0"" thereof and the partition e" is a drawer or coin receiver c and as plainly shownin Fig. 5 the drawer 0"" is provided with a lock 0', the tumbler ofwhich operates in connection with the front wall or cover of the supplemental casingc by means of which the drawer c' can be locked in position in the supplemental casing; and said drawer 0" preferably extends from the front part of the cover rearwardly to the base a as shown in Fig. 5.

.'\ccording to the construction above described, it will be seen, that the spring, c tends normally to hold the wrist pin c vertically under the shaft 1; and the recess is so located that its corresponding normal position is directly under the. coin chute a. The driving disk c is free to turn in the direction of the arrow 3 in Fig. (3, by means of a crank c", and the spring pawl is free to work over the tooth c" and when the pawl and tooth c" are adjacent as shown in Fig. 5 at c' the recess c" in the driving disk c registers with the recess a and is also-directly under the coin chute a, and the driving disk e is prevented from being turned ina direction opposite to the arrow y of Fig. 6 since the tooth 6 will strike the spring pawl e tending to turn the ratchet disk e which is prevented from turning by the pawl e. The rib e of the partition e as shown in Fig. 4 extends over and covers the opening of the space between the driving disk 6 andthe ratchet disk 0".

The operation of this machine will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statements thereof. The apparatus is, at all.

times, normally inoperative since as above stated the crank can be turned idly in one direction but is positively restrained from being turned in the other direction; when it is desired to operate the machine to produce for use a towel as hereinbefore mentioned, a coin such as a penny, nickel, dime or other coin is placed by the operator in the -upper end of the coin chute a. and on being released drops downwardly therethrough and is received by therecesses e and e, the coin resting in the bottom thereof, its shape conforming to the shape of the bottom of the recesses as shown in Fig. 4. The crank e is, as before stated, prevented from being turned to the left," but if itnow be turned to the right the driving disk e will move or turn the ratchet disk e because-of the coin engaging the edges of the recesses e and e as will be understood, and as the two disks are now turned together toward the right the spring c tends to resist the revolution of the ratchet disk 6'' throughout a half revolution thereof as will be understood, and when the driving disk c by means of the coin in the recesses e and c has turned the ratchet disk 0 more than a half revolution the spring-c" will tend to assist in the rotation of the disk 0' and the spring pawl a will engage and press upon the tooth e" and the two disks will continue to rotate together. \Vhen the 'coin in its revolution with the disks has reached a point shown in dotted lines at f, the lower end of the finger 0 engages the inner edge of the coin f, and on a further revolution of the two disks the coin is gradually pushed out by the edge of they finger c, occupying in this operation the position 7'", until at f the coin is entirely freed from the recesses e and c in the disks 0'' and c", and drops downwardly by gravity over the peripheries of the disks 6'' and c around under the rib c and into the drawer c \Vhen the coin has left the recesses as above described, the driving disk 0 is free to move independently of the ratchet disk (1 and the spring 0 operates to pull the disk c to a completion of its revolotion or toward its normal position, as shown in the drawings, and thereby causes p the spring pawl e to remain adjacent. to the tooth e", and thus the disk 6" and the disk 6 continue to rotate together, and when the complete revolution has been efiected the initial conditions are restored and a further revolution of the disk 6 is impossible without the insertion of another coin. As hereinbefore stated, the paper b on the roller 7) is fed between the two rollers 0 and d and, as just described, on the insertion of a coin into the machine, the roller 0 may be 'revolved through one revolution by means of the crank e and durin this operation a predetermined length 0 paper is fed be tween the rollers c and d thus giving the treatment hereinbefore mentioned of crimping or craping its surface, which give it a porous absorbent texture. The longitudinal row of recessesc and corresponding teeth (1 are so located upon the rollers '0 and (Z that when the said rollers are in their normal positions, these recesses and teeth occupyrelatively the osition shown in Fig. 7 so that on a compl tion of one revolution of the rollers above described, the predetermined length of paper towel is formed and fed out through the delivery slot at a, and is perforated or cut transversely by the recesses c 1and projections d and this trans- 0 verse row 'of perforations is fed forward to -and stopped at thetramsverse edge a of the delivery aperture 0, so that the predetermined length of towel or strip 5 maybe torn off along said edge. As will be understood in connection with L the above description, the rib e and the partition 6 direct the path of the coin' discharged by the finger e from the recesses c and c and prevent its falling off into the interior of the machine, and the point in the revolution of the disks 0 and a" at which the coin is ejected from the recesses e and e b the linger c' is determined by, and may e adjusted to occur at any dosirable point in the revolution of the said I :disks by varying the contour of the finger e and the length of the rib a as will be understood.

' The crank a will normally hang, due to its weight, at the lowest point of its revolution as shown in Fig. 4, or it may be held in this position normally by any'desired means, but it will be understood that if by accident it does not occupy this position when the coin is inserted, the driving disk 6 may be revolved idly in the direction of the arrow y of Fig. 6 until the recess .0 registers with the recess a" and with thecoin chute a when the coin will drop into the recesses e ends" and the machine may be operated as above described.

When the roll of paper I) on the roller b has becomeexhausted, a new one may be substituted by first removin the cover of the machine and then Iettmgdown the hinged pedestal a constructed as above described. r The method of connecting the cover to the base a may be modified and arran ed in any desired way and other details 0 the 'construction of my improved towel vending machine may be changed and modified without .departingfrom the spirit ofmy invention or sacrificing its advantages, and I do, not wish to be limited to the exact forms of con- 7 struction and details by which the principle of my invention is applied as herein set out. Although I have shown and described the feed rollersc and ,d as geared together by means of teeth or projections and corresponding recesses formed in the faces thereof, it will be apparent that these rollers may be geared together by means of gears at the ends thereof; or in any other desired manner, and by means of the construction herein de- 3 scribed, I provide a machine which will form from a roll of smooth paper a towel having a rough, porous and absorbent sur face or texture delivered for use upon the insertion of a coin in the machine and upon the turning of a crank to operate the same; but my invention is not limited to the construction, combination and arrangement of the various parts of the machine herein shown and described, since it Will be evident that a roll of paper previously craped and made porous and absorbent and previously provided with transverse rows of perforations or apertures may be used and fed out V between differently formed rollers controlled 00 by the coin operated mechanism described,

or some other form of coin operated mechanism may be used to control the corrugated feed rollers and perforators constructed as described; and various other changes in and modifications of the construction herein described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what-I claim as new and desire to secure by Letters Patent, is I 1.
