Each arm |8 is provided at its upper end with a cylindrical sleeve 28 preferably formed integral with the arm and inclined from the vertical as shown in Figures 1 and 4 to facilitate the operation of the device, as will become apparent. Each sleeve 28 supports a coin tube 29 projecting therethrough as shown in Figure 4. Such coin tube may be supported in any suitable manner, for example by a setscrew 35. Each coin tube is provided with sight openings 3| to facilitate determining the depth of the stack of coins in the tube, and each tube is preferably flared at its upper end as at 32 to facilitate the loading of the tube.

Below each sleeve is arranged a dispensing head 35 shaped generally as shownin Figure 1. Each head 35 is generally rectangular in plan and is provided with down turned flanges 36 forming an internal recess 31, open at the bottom of the head 35, for a purpose to be described. Each head 35 is provided with an upwardly extending annular flange portion 38 receiving the lower end of one of the tubes 29. Such tube is secured in the flange 38 in any suitable manner, for example by having a driving fit therewith.

A spacer block 40 is arranged in the recess 3! and is fixed with respect to the associated head 35 in any suitable manner, as by screws 4| extending through the side flanges 36. The spacer block 40 is provided with an opening 42 in axial alignment with and corresponding in size to the internal diameter of the tube 29, such diameter depending upon the particular coins to be dispensed from each unit.

The spacer block of each unit is associated with a movable coin dispensing unit indicated as a whole by the numeral 45. Such unit comprises upper and lower plates 46 and 41 the former of which operates in the space provided for this purpose above the spacer block 40, as shown in Figure 2. The plate 47 operates against the bottom surface of the spacer block 40. The plate is provided with an opening 48 normally arranged in axial alignment with the tube 29 and of the same diameter as the internal diameter of such tube. One edge of the opening 48 is tapered as at 49, Figure 4, to slice between coins of a stack in the device when a plurality of coins is to be dispensed, as described in detail below. The plate 4'! is provided with a similar opening 5| of the same size but normally offset axially from the stack of coins as shown in Figure 4.

The plate 46 has one end thereof turned downwardly as at 53, approximately perpendicular to the body of the plate 46, and is then bent inwardly at a slight angle at its lower edge as at 54. The corresponding end of the plate 41 has a down-turned flange fixed in any suitable manner, as by welding, to the down-turned end 53. Accordingly the plates 46 and 41 are fixed together for movement as a unit.

' The plate 41 (Figure 5) is provided with a slot Gil-receiving the shank of a screw 6| threaded in the block 4|! and carried thereby. The head of the screw 6| fixes the forward end of the plate 4"! against possible downward flexing. The inher end'of the slot 66 may engage the screw 6| to limit forward movement of the dispensing element 45, or the advancing edge 62 of the plate 46 may engage the surface 63 of the flange 36 to limit such movement. The limit of movement referred to will occur when the opening 5| is axially aligned with the coin tube, as will be apparent.

The spacer block 40 carries a stationary rod 65 threaded thereinto as shown in Figure 4 and this rod is surrounded by a spring 66 one end of which engages the adjacent end of the block 40 and the other end of which engages the end 53 of the plate 46. The spring 66 urges the dispensing element 45 toward the left to the normal position shown in Figure 4, and the inner stems 68 of screws 69, carried by the side flanges 36 engage the down-turned end 53 to limit movement of the dispensing element 45 to normal position.

Operation The combined arm and dispensing structures are preferably made up in units having tubes 29 and the associated coin dispensing elements in predetermined sizes according to the coins to be dispensed by each unit. These units are selected for connection with the base H1 in accordance with the requirements of the purchaser. The base l0 obviously will be the same regardless of the particular coins to be dispensed and will vary only according to the number of dispensing units to be supported.

The proper dispensing units and the proper base |ll having been selected, the finger piece 25 of each unit will be turned in the direction of the arrow in Figure 6, whereupon the associated lug 20 will be inserted in the proper opening H. The finger piece 25 will'be turned back to a position corresponding to the position shown in Figures 1 and 4 to bring the projection 24 into clamping engagement with the associated incline l6. Thus each unit is rigidly connected to the base HI, and is easily connected to and detached from the base. If, in the use of one of the devices, it is desired to change the denomination of the coins to be dispensed by any unit, such unit is readily detachable and replaceable by the desired unit.

Each tube 29 is filled to the desired extent with the proper coins and these coins will drop to the bottom of the dispenser to be supported by the plate 41, the opening 5| of which is normally substantially out of alignment with the coin stack. The number of coins to be dispensed at any given operation will be determined by the distance from the top of the plate 41 to the top of the spacer 40. For example, if quarters are to be dispensed, this distance normally will be equal to the thickness of four quarters, change for a dollar. If pennies are to be dispensed, the distance referred to usually will be equal to the thickness of five pennies, etc.

To operate the device, the operator will place his hand beneath the head 36, palm up, and with the tips of his fingers behind the flange 54, he will pull forwardly to move the dispensing element 45 in the same direction against the tension of the spring 66. The edge 49 will push ahead of it the coin lying in its plane of movement and will move beneath the next adjacent upper coin. The sharpened edge 49 facilitates movement of the plate 46 beneath the latter coin which, together with all of the coins thereabove, will be supported by the plate 46. When the dispensing element reaches its forward limit of movement, the opening 5| will align with the opening 42, and

the predetermined number of coins within the vertical limits of the spacer block 40 will drop through the opening 5| into the palm of the operator. The operator merely holds the coins and releases the finger piece 54, whereupon the parts return to normal position, the coin displaced by the edge 49 being moved back into alignment with the coin stack. Theopening 48 will again align with the opening 42 and the coin stack will drop to the extent of the thickness of the predeterdietersmined number j of coins previously dispensed? The device is readily assembled as willbeobvious from m dia gs, 'The sp'acer=blocks4fl may a l .7 miemasg ddn the desired depthf to predetermine the ofQcoins tobe dispensed.

If a purchaser of the device finds, for example, that he needs one less nickel tube and one more quarter tube to meet his requirements, he need purchase only a single quarter unit to replace one of the nickel units. Thus he is enabled to secure a dispensing apparatus as a whole fitted to his needs, and if such needs are not properly satisfied with the apparatus as purchased, it is merely necessary for him to buy asingle dispensing unit to replace one of the original units.
