Application filed August 20, 1917'.
To all w/iom t may concern.'
Be it known that l, ALBERT D. Gnovnn, a
citizen of the United States, and a resident of'New York city, in the county of New York and State of New York, have invented certain new and useful improvements in Coin-Controlled Vending Machines,of which the following is a specification.
My invention relates to coin-controlled vending machines, and has for its object the provision of a machine of small dimensions, especially adapted for use in theatres and other places where but little space is available for accommodating` vending machines. The machine of my invention is particularly adapted to sell cylindrical packages, although it is by no means limited to any special form or style of package.
The various features vof novelty residing in my invention will become clear from a detailed description of the accompanying drawings which show a preferred embodiment of my invention.
In these drawings,
Fig. 1 represents a rear view of a machine embodying my invention, the back of the casing being removed and the parts being in normal position.
Fig. 2 is a section on line 2,-2 of Fig. 1, looking in the direction of the arrows.
Fig. 3 is a fragmentary view in section on line 3 3 of Fig. 1', showing how the coincontrolled actuating lever is vlocked against movement when the supply of goods is eX- hausted.
Fig. 4 is a cross-sectional plan view on line 4 4 of Fig. 1, looking downward.
Fig. 5 is a side elevation of the machine shown in Fig. 1, with a portion of the casing broken away to show the working parts.
Fig. 6 is a view similar to Fig. 1, showing the parts in fully operated position.
Fig. 7 is a detached view in perspective of the magazine or goods-compartment, showing the coin receptacle attached thereto; and
Figs. 8 and 9 are detached views in perspective of the two partswhich constitute the coin receptacle.
The outer casing of the machine is preferably constructed in two sections,-a front section A and a rear section B. rlhe front section` A comprises a front plate 1, side Specification of Letters Patent.

pieces 2, and a bottom 3 which terminates at the point 4, as indicated in Figs. 2 and 5.
The rear section B of the casing consists of a rear plate 5, a top 6, side flanges 7 and a bottom flange 8. rihe top 6 is provided with a front flange 9, which meets the upper edge of the front plate 1 along 'the line indicated at 10 in Figs. 2 and 5.
l/Vhen the sections A and B are assembled, the side pieces 2 of the front section A abut against the side flanges 7 of the rear section B along the line indicated at 11 in Figs. 2 and 5. ln this way a closed casing is formed. The two sections are held locked together by any suitable locking mechanism, which I have not deemed necessary to show or describe, as it forms no part of my present invention.
Within the casing is mounted the magazine or goods-compartment indicated as a whole by M.y This magazine is preferably formed of sheet metal and comprises a front wall 12, side walls 13 and inwardly extendingrear iianges 14. The magazine M is secured within the casing of the machine in any suitable way, as by means of screws 15 which pass into spacing sleeves or collars 16 carried by the front wall of the casing.
Below the magazine M is mounted the rotary delivery member indicated as a whole by D. The member D is hollow and semicylindrical inform, comprising a main body portion 17 and side disks 18 and 19. For the sake of brevity, l will hereinafter refer to the member D as the delivery cylinder, without thereby intending to limit myself to the cylindrical form shown in the drawings. The particular form of this delivery cylinder will depend upon the form or style of the packages to be vended.
The delivery cylinder D is mounted in the sides of the casing by pivot pins or studs 20. The delivery cylinder is so arranged-with respect to the magazine M that in its normal position it receives the lowermost package P, as shown in Fig. 2, the remaining packages P1 being held in the magazine proper 21 is provided with a vertical slot 22 and. 2.
horizontal slot 23. The vertical slot 22 engages the pivot pin 2O and thereby guides the bar in its up and down movements. The slot 28 engages a pin 2a projecting from the disk 18, whereby the vertical movements of the bar 21 produce rotary movement of the delivery cylinder. These oscillatory movements of the delivery cylinder are limited by the fixed stop 241 engaging in the curved slot 25 of the disk 18. Any other suitable means may be employed for limiting the movements of the delivery cylinder D.
At its upper end, the bar 21 is provided with a transverse extension 26 which carries a pin or stud 27 arranged to engage in the slot 28 formed in one end of the bellcrank lever 29. This lever is pivoted at 30 to the front wall of they casing, and is at its upper end provided with a forwardly eX- tending pin 31 which extends into the coinpassage 32, as best shown in Fig. 2. The bell-crank lever 29 is normally held in the position shown in Fig. 1 by a contractile spring 33, which has one end fastened to the pin 34 of the lever 29 and the other end to a pin 35 fixed to the casing. A fixed stop 36 limits the movement of the lever 29 under the action of the spring` 38.
The slot 28 of the bellcrank lever 29 has a concentric portion 282L and an angular portion 28h, the purpose of which will be pres- -ently explained.
The casing is provided with a fixed stop 37. l/Vhen the bar 21 is in normal position, the outer end of the transverse extension 26 thereof is below the stop 87, as shown in Fig. 1, so that the extension 26 must first be moved laterally out of the way of the stop 37 before the bar 21 can be moved vertically. This preliminary release or unlocking of the bar 21 before its operative movement can take place, is effected by the angular portion 28b of the slot 28 in the actuating lever 29. TWhen the lever 29 is moved from its normal position in the direction of the arrow c in F ig. 1, the lirst thing that happens to the bar 21 is a lateral shifting of the extension 26 to move it out of alignment with the fixed stop 87. This lateral shifting takes place while the pin 27 of the bar 21 engages the angular portion 28" of the slot 2S. Further movementof the lever 29 brings the concentric portion 2S of the slot 28 into engagement with the pin 27. This movement of the lever 29 until the bottom of the slot 28 reaches the pin 27, has no e'li'ect upon the bar 21. for the portion 28n of the slot 2S is concentric with the pivot 30 of the lever. ln the particular form of machine illustraterfl, this lost motion of the bell-crank lever 29 is for the purpose of testing the deposited coin C which engages the pin 31 of the lever 29. The deposited coin is carried against the pin 31 by any suitable means, such as a coin disk 38, which is Operated from the outside of the casing by a knob 39. So far as the ej ecting mechanism of my invention is concerned, any suitable means may be employed for actuating the bell-crank lever 29 from the outside of the casing.
After the bottom of the slot 28 has reached the pin 27, continued forward movementof the lever 29 raises the bar 21. This upward movement of the bar 21 causes the delivery cylinder D to rotate in the direction of the arrow Z), as indicated in Figs. 2 and 5, whereby the bottom piece of goods is discharged into the position indicated at P2 in Figs. 2 and 5. A slanting guide 11 is preferably provided to receive the package as it drops from the cylinder and to guide it towardthe front of the casing, as shown. The side walls of the casing are provided with openings 4l() through which the ejected package is removed by the purchaser. j f
It will be clear from the foregoing that the fixed stop 37 positively prevents operation of the delivery cylinder from belowas by an instrument insertedthrough the delivery opening in an effort to rock the cylinder. Should an attempt be `made to operate the cylinder in any other way than through the medium of the lever 29, theextension 26 will strike the fixed stop 37 and the delivery cylinder is at once locked against movement. j
As soon as the coin C passes out of engagement with the pin 31 of the lever 29, the spring 33 returns the lever and its connected parts (namely, the bar 21 and the delivery cylinder D) to normal position. During the delivery posit-ion of the cylinder D, the column of goods rests upon the outer surface of the main section 17. As the cylinder D reaches its normal position, the lowermost package drops down into the cylinder, as shown in Fig. 2, and the machine is ready to deliver tlie next piece of goods.
In order to prevent the loss of a coin to an .intending purchaser when the supplycf goods is exhausted, l provide means for locking the member 29 in normal position after the last piece of `goods has been ejected. A pawl Zl2 is pivoted intermediate its ends on a -pin or lug 413 carried by the bracket ifiwhich is secured to the front plate 1 of the casing by any suitable means, such as rivets 4-5. At its upper end the pawl 41-2iis provided with a hook 4:6, and at its lower end with a hook f1.7. The shell section 17 of the delivery cylinder D has an opening l8- through which the hook l17 of the pawl 42 extends when the delivery cylinder is empty.
, lWhen there is a package in the delivery cylinder, as indicated in Fig. 2, or when the cylinder is in delivery position, as indicated in Fig. 5, the pawl 4t2 is held in such position that the upper hookl@ is out of the path of movement of the lever 29. However, after thelast piece of goods has been ejected and the parts have returned to normal position, the lower hooi; a7 snaps into the opening 48 under the action of the spring 4:9, and the upper hook 46 engages the shoulder 50 of the lever 29, thereby positively locking the lever against forward movement. Consequently, when the lever 29 is thus locked, the deposited coin C cannot be carried further into the machine than indicated in Fig. l. However, the coin-carrier 38 is free to be rotated in the opposite direction to carry the coin C back through the coinentrance slot 5l, whence it maybe removed by the purchaser.
lVheuthe deposited coin is discharged from between the coin-carrier 38 and the .pin 3l ot' the lever 29, it falls rearwardly through ythe opening into the chamber 53 formed between the front wall of the magazine and the front wall oi the casing. At the bottom of this chamber is a coin-retaining piece on which the discharged coins rest. ln the particular embodiment shown in the drawings, the coin-retaining piece 54 is pivby the front wall 12 of the magazine. rilhe lugs 59 engage in slots GO in the bar 58. lllhen the two sections of the casing are assembled. the upper end of the bar 58 rests against the top of the casing, as indicated in l? 2, and thereby holds the coin-retaining piece in horizontal or retaining position. Then the front section A is removed from the rear or stationary section B, which isintended to be fastened to a suitable support (as for instance, a theatre chair), the weight of the coins on the retaining piece 54 will over-balance the weight of the bar 58 and tilt the piece 5a downwardly to release the coins. Then the .iront section A is put back on the rear section B, after the coins have been collected and the machine replenished, the bar 58 must be forced down so as to fit within the top G of the rear section, and this forcing down of the bar 58 swings the retaining` piece into norma-l or coin-retaining position. ln other words, the coin-trap which I have provided for receiving the d ischarged coins must be in closed position before the front section can be put back in place on the rear section of the casing.
Although l have herein shown and described a machine of specific construction, I would have it understood that the various features of my invention are not limited to lthe details of construction set forth. It is obvious that changes or modifications may be made without departing` from the invention as defined in the appended claims.
Having thus described my invention what l claim as new and desire to secure by Letters Patent ot the United States, is:
