the; orinot a pinrotatably mounted in a socket 26 in the forward edOe oi' board l?A and the ystop 2l preferably is in the torni ot a plate having a recessed porri n 2? opening` toward the stop E2G.

lt may be stated, as a preface to the tollowing description that the delivery oi' the papers one by one into the outlet 1S is effected in the particular construction of machine illiistrated, by lirst shitting; the forn wardinost paper to the right in Figure 2 vto the Right-hand posit-ion designati-rd in this figure in which posit-ion the lett-hand edge of the forwardinost paper clears the stop and is projected Jforwardly by the action et the Jfollower 22, the paper then being'V siiiited to the lett in `Figure 2 to the Leit-hand position noted thereon, in which position the paper clears the stop 2l and extends into the outlet i3, a desorption or" the inechanisniE by which the papers are disrention, 1being as follows: tlieioi`- Ward' all 2S oi the l5, is equipped with horizontally extending guide bar preferably dove-tail in cross-section which guidingly supports a horizontally inovable bar, or slide, equipped with a stud 8l which extends forwardly and into an elongated slot 32 provided in the iront Wall ot a. casing, or housing, 34 secured tothe Wall 28,pre'tera'bly by the hinges B5 and a lool; device 36, vto house the delivery mechanisin. The guide 29 at the lett-hand side in Fig. 3 is formed with stop surfaces for limiting the inovenient ot the member SO tothe leiit in Fig. 3, and a coiled spring,

represented at 38, land connected at its ojaposite ends With the Wall QS and with the slide 30, as indicated at 39 and 40, respectively, operates to'norinally hold the slide in the position shown in l and alitoniatically Vreturn it to this position when position shown The ,casing Wall 28 adjacent the lower endV of the ineinber 4l is apertnred as represented at 4Q, this aperture extending opposite the prong-equipped portion 43 or the member 4l and a shoe section 44 thereof, Whenthe latter, upon nioyeinent oi the slide 30 to the righi iV i@ a, presser @ed per@ rnce With the preferred nnb-odiinentl passes the end ot a restraining` member hereinafter referred to. The prong-deVice 43 is preferably constructed as shown in F 6 and 7, nainely by pivotally connecting, as through the medium of a pin 45, ahead 46, to the lower end of the section 4la this pivot extending in a horizontal posit-ion and the head 45 containing a vertically-extending tl'ireaded aperture 47 in Wnich a threaded rod 48 is screwed and is thnsfrotatabiy adjustable, a .lock-nut 48a'being screwed on is shaft. The rod 48 has screwed into it to extend in a generalrearnard direction, prongs 49 pointed at their rear ends yto pierce Athe ifornf'ardinost paper yto be deliverec theseV prongs inclining and alten nate ones inolining` in the opposite direction as clearly represented in the drawings, the mounting of the prong portion 43 as @rated adaptingv it to roclcnpon the member "ll-to insure the desired `grip on the paper when the member 41a springs rearwardly toward the paper as hereinafter described. The shoe 4' preferably` formed of a sec- ,i tio i 50 integr ai with the inetal forming the slide 30 to the right in Fig. l, the shoe moves along the forward side of the sec- 1 -01 ,1 17j V() n q the i irais or are on, am as oon as c sico i i. clears the right-hand end of the section in Fig. l, the section 41a is rapidly projected at its lower end by the spring; 41d, rear-k wardly in the direction of the articles 19,., to drive the prongs 49 against the 'forwardl inost article. The parts referred to are so arranged that the prongsV 49 are driven against they torwardinost article at snch a point in the increment ot the slide to the right in Fig'. l thatcontinned movement oi' the slide to the right in this ligure While in engagement with the torwa'rdinost article 19, will more the latter to the g"Riglitt-hand position indicated in Fig,

the. prongr device 43 in this operation ex-V tending through the recess 2? in the stop 2l, and as the paper shifts to the right to the position jnst statedV it moves against the pin 20 which, being free to rotate, practically eliminates friction. The casing Wall 28 also carries a forwardly vi'nojecting canidevice 5'4" presenting the cam-surface 58 which is so post" and-formed, as l` wn,

that' in the movement of the slide 30 to the left in Fig. 3 the member 41a will'y ride upon thecam-surface 58 at the time theshoe 44, in moving'V along the rear surface of the restraining sect-iony 52, opposesvthe slot- 5S, with the result, in the continued movement ofthe slide SOto the left to thel position shown in Fig. 1, ofswinging the member 41a forwardly against the tension ofthe spring-device 41'd to theposition shown-in Fig. 4, the shoe device 44 passing through the slot 53, in which operation the spring 54 fl'eXes forwardly., and thereupon passing beyond the free end of this spring to a position where itI opposes they forward surface of thev restraining' section 51V thereby repositioning the parts for the repetition of the operations just described, it being understoody that by the timey the member 41 has been retracted' forwardly to a position in which the prong device 48 disengages from the paper, the latter will have been shifted tothe left in Fig: 2-to theLeft-hand position indicatedtherein in which the paper extends Within theoutlet 18.

lt is preferred that some means be provided for receiving and releasably supporting-` the left-hand end-of the paper after it has been moved to the Right-handposition indicated' ine Fig. 2 andI in which position it extends forwardly of the Ypin 20, and to thus hold this endof the paper in snp'- ported condition until the prong device 43 disengages from. the paper, this being accomplished' in the preferred construction illustrated by the provisionA of the restraining member represented at 59 andv preferably formed 'of two sections 60 and 61 pivotally connected together at 62", the section 61 being connected atits upper end with a cleat 63 on the wallt 28 and the `lower end ofthe section Obeing of'V curved form as shown to provide a ledgeV 64 adapted'to be projected through an opening Gain the iva-1.128 into the path of downward movement of the paper 19 when disengaged from the stop 20 as hereinbefore explained, the means for thus projecting the section 6() comprising a spring member 66 secured lo the cleat 63 andbearing at its lower endv against the member 60. The section 60 co-operates with a cani 67 which is carried by theY slide 30 and extends forwardly therefroin, the cam surface inclining from the rear, to the front of theL machine from the left-hand end to the right-hand thereof in Fig. 1, the form of: this cam and' its position on theA slide; 30 being such' as represented, so asV to permit thespring to project the member 64 into the 'path of the descending paper preferably about the saine time as the prong' device 43, inv movin-g to the rightY in Fig. l', engages with the forwardnrost paper, andpermit themember 64 tol remain'in' this position' until. the prong device 43 disengages from the forwardmost paper, the cam 67, by preference, operating the vending of'either'two-cent or seven-cent papers, a description ofthefillustrated coincontrolled mechanism being as follows: pivotally supported on a pin 68 to extend'below the top 69 of' the housing 33 are three dogs in the form: of levers 70, 71 and 72, the right-hand ends of these levers in Figs. 12, 13' and 14 being equipped with shoulder portions 73 adapt-ed yto interlock with a shoulder 74 on the upper side of the slide 30 in the 'normal position of' the machine (Fig. l). These shouldered ends of the levers are heavier than the opposite ends and extend across a cross-piece 7 5 formed as a part of a coin-releasing member hereinafter referred to. The short ends of these levers are preferably bifurcated as indicated aty 77, 78 and 79 and present in the normal position thereof illustrated in Fig. 14, inclined surfaces '80, 81 and 82 for a purpose hereinafter stated#v The bifurcatedv portions 77, 78 and 79, whichertend within a casing 7 6, are, opposed to, and in alinement with, slots 83, 84 and 85 respectively, formed in `the end of the cleat. The slot formed of the bifurcated portion 77 and the slot section 83 is provided for receiving a livecent piece and the distance-'from the base, ofthe slot 83 to 'the surface SO when this surface parallels the basev of the sloty 83 upon.

.rocking ,the lever 70, is preferably equal to the diameter of a five-cent piece so that when a coin is pushed intothis slot it will rock the lever 70 and swing the shouldered portion 73v thereof out of engagementv with the shoulder 74. The bifurcated portions 7 8 and 79 co-operating with vthe slottedportions 84 and 85 are provided each for receiving a penny, and the vdistance from the innermost portions of theseV slots't'o the sui'- faces 81 and 82'when these surfaces parallel the innermost portions: of the slots 84 and 85, is preferably equalto the. diameter of a penny so that when pennies are pushed into the slot they will roch the levers 71 and 72 to a 'position in which their shouldered portionsk 73 disengage from the shoulder 74 on the slide 30. vThe upper part ofA the cas ing7b` contains slots registering withV the. slots 83', 84l and 85, one" only otwhjich .is shown at 87'tliese slots in turnregistering with' slots 88, 89 and 90 in a meinberflfl con'.- finedin an opening 92 in the top 59 ofthe h'ollising'tlie' SQtSSS, 89A` andj Si? .heine tliu `coin-controlled and as shown is adapted for j l no ifa

. 70, 71 and 7 2 to a position in which the coins introduced into engagement therewith as above stated, are permitted to drop through the slots 33, 84: and 85 and into a boi: 86. In order that the member 93 be operated as stated its lower edge is inclined downwardly from its leiftshand end toward its right-hand end ig. 3 to present the inclined surface 9:5 which entends into lthe path of apin 96 carriedby the slide 30, in the final movement oi vthis slide to the right in Fig. 1, as represented in F 3.

In order that the slide 30 beloclred against return movement, after release oi thelocling shoulders 73, before the slide has been shii'ted to the'extreme position shown in Fig. 1, I provide the pawl 97 pivoted at 98 on the wall 23 antico-operating Vwith a centering spring 99 confined between two pins 1 00 on the wall 28, the upper tapered portion' of the pa-wl 97 extending normally above the plane of the lower surface of a cleat 101 secured to the bottom ot the slide 30, thisv cleat in the position of the machine shown in Fig. 3 Iextending wholly to the right or" the pawl 97 and in the position of the slide 30 in Fig ure 1 extending wholly to the left oit this pawl. Thusl in the movement of the slide 30 to the right in` Fig. 1 the pawl'97 dctlects in clockwise direction upon becoming engaged by the cleat 101 .and prevents retraction of this slide to the left until the leithand end loit this cleat has passed the pawl 97 3) in which position the forwardmost paper 19 has been disengagedfrom the stop 20; and in the movement of the slide 30 to the left from the position indicated in F ig. 3, the pawl 97 becomes deflected in anticlockwise direction by engagement therewith of the cleat 101 and thus prevents retraction of the slideY to the right until the righthand end of the cleat 101 has passed beyondV the pawl 97.

The operation or" the machine is as follows: Assuming the machine to be in the normal position represented in Figs. 1.11, 8, 10 and 11 to 111 inclusive, and that it is to be operated by the depositing of a nickel and two Vpennies into the machine, the operator pushes a nickel into the slot 88 and a penny into each of the slots 89 and 90, the coins engaging the inclined surfaces 80, 81 and 82 of the levers 70.I 71 and 72 and lifting all three thereof which, as will be understood, are independently operative, into a position in which the shoulder-S73 disengage from the shoulder 711. The operator then grasps the handle 31 and shifts the slide 30 to the right Eig. l to the position shown. in Fig. 3

with the result ot' eiiectin the rearward 'movement of the` prong-device 113V into en-V Fig. 1, it being understood that'thefpaper Y supporting member 611 in the movement ot the slide to thc right in Fie. 1 is projected f into the path of downward movement oi2 the left-hand end orn the partially released paper which latter falls upon it. In the movement of the slide 30 from the position shown in IP ig. 3 toy normal position (llig. 1), the prong-device 113 remains in engagement with the orwardmost paper '19 until'the righthand end ot the paper has passed beyond the left-hand edge oi' thefstop 21, the member 41a in such position engaging the cam 57 and the cam 67 engaging the member 60 yto withdraw the prong-device 43 from en gagement with the paper and the supporting member 60 from beneath the left-hand end of the paper Ato permit the latter to drop through the outlet 18, the member 111 and the shoe 11e becoming repositioned 'for repeating the delivery operation as hereinbe fore explained. y

In the movement of theslide 30 to the iight in Fig. 1 to theposition shown in 3, to 'disengage the torwa-rdmost paper. 19 from the stop 20, the member 93 rocks upwardly thereby effecting the discharge of the coins into the coin-box 86, the levers 70, 71V and 72 dropping to a position in which their shoulders 73 rest on the slide 30 and when the slide is returned to normal position the levers automatically become interlocked with the shoulder 711 to lool; the delivery mechanism against actuation until the proper coins are introduced into the machine.

In the particular construction of machine illustrated I provide means for shutting oiil the slot 83 and locking the lever 70 in a position in which its shoulder 73 is disengaged from the shoulder 711, 'in order that the machine may be operated with two pennies introduced, respectively, into the slots 89 and 90, these means comprising a slide 95a which is insertable into the space between the cleat 63 and the top ot the casing 76 directly above the slot 83 and upon being pushed to the right in Fig. 111 not only closing the slot 38 but also tilting the lever out of interlocking position with theV shoulder 7 Thilo I have illustrated and described a particular construction embodying my invention I do not wishV to be understood as intending to limit thereto, as the same may be variously inedite@ Willits? dep arting: from 'the spirit 'of' niyinvention,
