BAG-DISPENSING ,MACHINE Application filed December 31, 19,25.

My invention relates to a `bag dispensing machine.`

The object of this invention is to provide a machine which may be conveniently used for dispensing paper bags singly from piles of bags. The device is intended. for use in stores, fruit stands, and the like places where goods areplaced in bags for deliveryto customers. The invention is intended to draw single bag from astaclt of bags and to bring said bag outside of an enclosing casing where it may be conveniently engaged by the :lingers of the user,

The manner of operation of the device is to provide means for holding stacks of bags in fiatwise position with the side thereof towards which the bottom has been folded downward and 'to engage said bag by the inward edge of the folded bottom.

My invention consists of certain novel constructions and lcombinations of parts which will be hereinafter described and particu* larly pointed out in the claims. In the accoinpanying drawings, l have shown my inif'ontion embodied in constructions of a specific form which is now most preferred by me. lt is, however, Well understood that many of the specific features of construction herein shown may be replaced by other and equivalent constructions without, in any sense, destroying the character of my invention. The drawings are therefore to be understood as merely illustrative of the principles of my invention and the type of meehanism which may ie employed therein.

Figure l is a top or plan view of the mechanism employed for dispensing bags from a pile. Figures 2 and 3 are longitudinal sections through the casing which contains said mechanism, said section being taken entirely outside of the operating parts. ltigure el; is a section taken substantially on the plane of l Figure Figure 5 is a side elevation of the bag engaging lingers associated with a broken line, which, in a dia.- gi'aininatie manner, illustrates the manner of movement given said lingers in engaging and removing a bag.

l prefer to enclose the operating` parts of my device within a easing l, which is made of such si ze as 'to snugly hold a stack of bags of the size which it is desired to use. These casiwts would preferably bevaried in size for `if.' .rent sizes of bags andthe bag would espe-1,ed"toV snugly *fill tlie case. These Serial No. 78,551.

easings or holders may be employed as drawers to slip into suitable holding cabinets; such cabinets, however, have not been illustrated. Such drawers or casings may be freely open at the top, or could bemade `closed as desired. Means should, however, be provided for easy insertion of the stack of bags. On the under side, the use of a floor to hold the bag, or the provision of transverse supports, suchas the bars 2, is immaterial. It is, however, necessary that, at that yend which `re ceives the bottom end of the bag, the support be open at the bottom sufficiently to perinit removal of the single bag downwardly. At this end, a transversely extending ledge or other analogous support, Vas 2G, is employed for supporting the eXtreme outer end edge of the bag bottoni. This is illustrated clearly in Figures 2 and 3 vwherein the stackof bags is indicated at 2l. 'i

The end of the casing at which the bottom ends of the bags are placed is pro-vided with' an opening, as 10, extending preferably from `the supporting edge 9.() downwardly. It is through this opening that the bags are Withdrawn. Mounted to be reciprocated lengtl'i wise of the bag in guides, as 30, is a slide 3. The bags are supported at sutlicient elevation above the bottom ll of the casing or holder l, to accommodate the mechanism by which single bags are engaged and removed. The slide 3 carries two bag engaging lingers. One of these, as the finger d may be made a fixed linger, that is one which is carried by the slide 3 and has no movement except that of the slide. As herein illustrated, this Enger is made as au integral part of the slide. The particular manner of yits construction, however, is immaterial. This iinger-has its outer end positioned at such a level 'that it will pass above the folded inner edge of the bag bottom as the bag lies in the stack.

(lo-operating with the finger l is the movable linger 5. This is pivoted at 5G upon the standard which carries .the fixed finger 4l. lt has a rearward eXteinsion which lies Vover the transversely mounted y shaft 5l.. This shaft is journaledti-n standardsearried by the 'slide and is d signedto be given a liniited rotclring moi-ement. At being `the point of such shaft which is beneath the rearward extension of the linger 5, the shaft 5l is i ansversely resesl -.SQ :aS to form, in eect, a 'ca-rn by" which the rear end of this ylinger may be raised when the shaft is rocked upon its axis. The movable finger 5 is normally held with its outer end towards the linger et by the use of a spring, as 54, which operates in conjunction with a pin or rod 55.

rIhe transversely extending shaft 5l, extends beyond the edge of the slide 3 and is provided with two radially extending arms 56 and 57.

The slide 3 is intended to normally be towards the rear end et the bag holding` ease or drawer. This result may be secured by the employment ol" a spring connecting the slide with the rear end ot the ease. The spring as illustrati-id, is a compound spring, the spring G being a helical spring which is secured to the slide at one end, .its other end being secured to the opposite end et a tube 6l, within which is secured the second spring 60, which is secured to one end ot' the surrounding tube and to the rear end of the casing. The object ot' this construction is merely to get the possibility of long range or extension into a small space. Such spring-ot whatever type employed, should be such as would normally draw the slide to the rear and hold it in its rearmost po sition.

Mounted close along side ot the slide, or in whatever position is most convenient and feasible, is a rod 7. This is the operating rod and is mounted so as to be freely reciprocable, and parallel with the guide 30. This rod hastwo pins or stop lingers mounted thereon. The linger 7 (l, which is placed iminediately back of a pivoted bar or arm 7 2, carried by the slide, is designed by engaging the said arm 72, to cause the slide to move outwardly whenv the bar is drawn out wardly. At the point 8 is provided a cam tinger or bar designed to engage the outer end ot the bar or dog 72 to raise it sutiiciently so that it will be 'treed from the pin 7() carried by the operating bar 7. As the slide has been moved out by the engagement ot the pin with the arm 7 2, the springs (i and GO ha 'e been stretched. Therefore, when the pin 7 O and arm 72 are disengaged. the slide and the lingers Carried thereby will be retracted. However, the pin 71, which plaeed turther to the rear upon the operating bar 7 projects to a greater height than the pin 70 and will then engage the bar 7:2 to cause the slide to again be moved torw rd l Art the tiret movement of the slide torwardly, or towards the discharge opening l0, the fingers fl and 5 will be caused to engage the 'folded inner edge ot the bag bottom as is shown at The spring' 54 causes the fingers to grip the bag bottom. A positive opening ot the lingers at the time they are inserted to engage the bag bottom is secured b v the engagement oi, the arm or pin 57 earried by the Shaft,v 5l with a fixed stop ask 5S.

This, by the rocking f the shaft, opens the lingers. rThe lingers, therefore, are caused to engage the folded edge ot the bag bottom so that when the slide is released for its baele ward movement, the will be pulled back ward sutliciently to free it from the support`- ing ledge 20. Therefore, when the slide is moved outwardly in its tinal movement, the bag will be carried along therewith so as to draw its end to or beyond the easing, in accordance with the lne-vision made in the design ot the device. At this point., as the slide returns, the arm 56 will engage the stop 59, so as to rock the shait't 5l in the opposite direction, which, however, in a similar manner releases the grip of the fingers upon thebag.

Provision should be made for the automatic return ot the operating bar 7. The most obvious mians tor doing this is a. spring. l have shown a spring 73 as connected by one end with the rod 7, as at 74, and by its other end with one end of the bar or arm 75 carried by the slide. By this expedient, that is, by supporting one end of the spring from the slide, the length of the spring can be made less than would be required it' this end o't' the spring be anchored to the easing. Upon the return of the slide under the influence of the springs 6 and 60, 'linger Carried by the shatt 5l will engage a stop or linger 8. so as to assure the turning o't' `the shaft ba *lt to the position in which the spring is tree to hold the lingers together.

The actionof this device is as follows: Bags are supposed to have been put in place with the folded bag bottom downwardly and with this end or back toward the outer end ot the holder, as is clearly indicated in Figures 2 and 3. When a bag is desired, the operating arm 7 is engaged and drawn outwardly. The first result ot this movement is to draw the slide and its lingers 4t and 5 outwardly until they have engaged with the tolded inner edge of the bag bottom, as is clearly shown in Figure At this point, the engagement between the lug or pin 7() earried by the ope ating bar7 and the hinged arm 72 carried by the slide, is treed by the raising` ot the arm 72 through .its engagement with the cam incline S. ln consequence the slide is drawn quickly lo the rear by the action ot the springs thereon. As a result ot' this, the bag bottom is pulled rearwardly sutiiciently to tree it troni the supporting ledge or' bar 20. he pin 7l then engages with the arm or bar 72 to cause the slide to again move outwardly. This outward movenent causes the end of the bag to be drawn outwardly so as to project it somewhat beyondthe end oiz the bor: or container l. At this point the grip of the fingers upon the bag has been relieved by `engagement oit the 'linger 57 with the stop 553i, Therefore, when the operating bar is permitted to be witb- (lll FIJ
