Arm'42" is pivotedat"4'5to one endlof' 1ink"46 the other end of which is-pivoted at 47to arm 48 -att'ached to rock shaft'49.

R'ockshaftf49- is mounted for rotation in a pair. of identical U-shaped" bearingfmembersfil' integrally at.- tached' to plates 50 mounted'onend plates 23" and241 One-"of. these is shown in detail in Fig. 12; The shaft isretained. by. any suitable means, shown. herein as a cotter pin. 52 passing through openings in bearing 51'.

Suitably, attached to shaft 49' are a pair of arms 53; 54, which may be identical, butare here shown as allochiral. The arm 53 is shown in detail in Fig. 3; and has a lip 55 turned-at one end to act as a stop as hereinafter explained; Piv'ots'56and 57 on arms 53 andS i mount eject'or'niea'n's 58' and59. Ejector 58 is shown indetail in Fig. 3 and has at its outer end a pin 60,,the purpose of which will later appear. Also on ejector 58 is a slide 61of substantiallyrectangular. cross section tubing, which acts as astripping. means.

The lowerend of arm 53 has an L-shapedportion 62 havingani' opening, 63 therein. Connected to opening 63 and to bolt 64011 slide 61 is a link? 65. Also' connecting ejector 58 and arm53 is a sp'ringi661 Itlist'o' be understood that. ejector '59 isprovided' with elements as described above for'ejec'to'r'58which are identical ex cept' for the allochiral: arrangement shown in Fig. 1.

Mounted on the front plate 21 is a coin. chute 67- having a hopper portion 68; a discharge" portion 69 and aniinvertedtrough portion 70 Chute 67' is mounted on plate 21 by brackets' 71, 72" and" screws 73*, 74. Located on panel 27, above hopper 68 is a coin slot 75. The discharge portion of the-chute. is shown in Fig: 7' as having furcations 76, 77 and upstanding flanges 78 and. 79. The furcatio'ns'76 and 77 provide a slot 80 to. ac" commodate tripper 81 forswitch 82. SWiIChSZ iS shown in Fig. 8' and comprises a conventional mercury switch tube 87 pivotally mounted on pivot 83 on bracket 84 and having lead-in contact members 85 and 86 as is usual in a single pole single throw' mercury, switch;

A single pole switch 88 suitablymounted on panel 23 is the main switch. This switch is suitablyconne'ctedi to switch 82 and to the battery 31. Located between switch 82" and motor 35 is a safety" switch 89, as shown in Fig. 11, whichmay bea conventional microswitch housed in housing 90 attached to bracket 91. This switch has an operator 92 having a lazy S-shaped form With an upstanding portion. 94 for a purpose which will later appear. Connections are made to switch 87 by binding posts 95 and. 96.

As shown in Figure 10, an- L-shaped bracket 97 fastenedtofalse bottom. 30 by suitable fastening means.

98 extends the length oiithev machine and has attached.

thereto near switch 82. a. plate the upper end of which.

is. bifurcated, and the. furcaticns of which have turned over end portions 10%;. 1 01% constituting hinge. or pivot means for bent' 'lever 102. Lever 1% has a downwardly extending portion. 103:- and a substantially horizontal portion 104'. The downwardly extending portion- 103 extends substantially across a slot. 105 which extends'substantially the length of false bottom 3h adjacent bracket 97. 'The horizontal portion of lever 102- extends normally beneath switch tripper'81 and normally overbalances portion 103.

Adjacent slot 105 opposite bracket 97 is a substantially L-shaped bracket or ledge 106 fastened to false bottom 30 by screws 107. This bracket constitutes a stop plate to engage the fold portion of the forwardmost newspaper placed over false bottom 30.

Below bracket 106 attached to false bottom 30 by screws 109 is a downwardly curved plate or J-shaped chute 108 having at its outer end an upturned lip 110. Front plate 21 and bottom 29 are spaced from each other to provide a gap 111 to accommodate plate 108 and thus provide an ejector chute for papers delivered by the machine.

To position the papers with the forwardmost paper against bracket 106 there is provided a follower plate 112 mounted at an angle to the vertical, as shown in Fig. 2, and provided with a brace 113. Mounted on false bottom 30 is a pair of track members 114 and 115 which may be shallow channel members. Slidably mounted in the track members are the ends of two slides 116 and 117 connected by straps 118 and 119. The follower plate .112 is connected to slide 117 and the brace 113 is connected to slide 116.

An arm 120 is pivoted at 121 on false bottom 30, and is provided with a plurality of holes 122 to receive selectively one end of spring 123 anchored at 124 on false bottom 30.

Curved plate 108 is cut away as at 125 to provide a finger opening for grasping a paper delivered by ejectors 58 and 59.

In Fig. 6 the' coin chute 67 is shown as an inverted trough. This permits escape of coins and slugs of a diameter materially smaller than those which should operate the machine.

A bracket 126, Figure 2, is suitably mounted on back 22 and a latch 127 is pivoted at 128 thereon. Latch 127 has a hook 129 at one side of the pivot and an operating handle 130 at the other side of the pivot.

Arms 131 and 133, Figure 1, attached respectively to end walls 24 and 23 and having eyes 132 and 134 thereon, respectively, are positioned to prevent papers being pushed too far forward.

Ann 120 is forced by spring 123 against brace 113 to advance follower plate 112 against the stack of papers in the machine, as shown in Figures 2 and 9.

The lid or top portion is hinged at 135 on the back section, and a lock 136 is provided on the front 21 to prevent opening.

To prepare the machine for operation, the top 25 is opened, follower plate 112 is pushed back and the upper edge thereof engaged by book 129 on latch 127. A stack of papers is placed in the machine with their folds down and the forwardmost paper against bracket 106. Follower plate 112 is then released and presses the papers firmly against bracket 106. The degree of pressure can be adjusted by placing the end of spring 123 in the desired hole 122 in arm 120. Switch 88 is closed and as the forward edge of the stack of papers presses against operator 94 for switch 89, completing the circuit to the motor, except that switch 82 is normally open. Since tripper 81 of this switch extends into the slot 80 of chute end 69, a coin dropped through slot 75 into hopper 68 will slide down chute 67 and rock switch element 87 about pivot 83 to close the circuit through contacts 85 and 86. The mercury switch remains closed due to the overbalance caused by the weight of the mercury. This will complete the circuit to the motor and shaft 36 will rotate and through the internal gears, will oscillate plate 41 and arm 42. This, through link 46 and arm 48, will rock shaft 49. As shaft 49 rotates in a clockwise direction (Figs. 2 and 3) the upper ends of ejectors 58 and 59 will engage the forwardmost paper. Pin 60 will penetrate the forwardmost paper slightly and lift it above the bracket 106. Further operation of the motor will rock the shaft 49 counterclockwise, and tail 137 on ejector 58 will engage lip 55' on arm 53. The counterclockwise movement will cause slide 61 to sheath pin 60, releasing the paper. As the paper drops onto plate 108 it engages portion 103 of lever 102 rotating it to cause portion 104 to engage tripper 81 and raise it to open switch 82, thus stopping the motor. This completes one cycle of operation which is repeated each time a coin is inserted and papers are present. When no papers are present switch 89 will open to disable the machine.

The coins may fall onto the false bottom, but may be collected in a cup or other suitable receptacle placed under chute portion 69.

It is to be understood that while a specific form of the invention has been delineated herein, it is by no means to be considered so limited except within the scope of the appended claims.
