engage the sacks or bags the numeral 42. The pad neoprene or other material friction grip for the bags.

44 of the head piece l8 sacks in order that the extend beyond the sucguide for approaching ceeding sacks so that the former may be readily grasped by the operator. To aid in extending the forward sack 46 in this manner the flat springs 48 may be secured to the side members 24 and the sack advancing member 36 may be inclined forwardly as shown.

In placing the sacks or the bags in the dispenser, the sack advancing member 36 may be brought to the back of the dispenser, and a hook 50 pivotably connected to race arms 32 by ring 52 may be hooked over the rearward part of channels 26, thus holding the member 36 in a retracted position in order that the sacks 42 may be conveniently placed inthe dispenser. Many commercial sacks or bags have an extending upper edge 54 on the same side as the box portion 56 of the sack, and in order that the device may automatically open the sacks it is necessary that the Side on which the box portion of the sack is folded be grasped, and the pressure feed and the yielding frictional contact effected by the bag advancing member 36 and the stop 3t and the friction pad 4!] against the lower portion of the sacks will effectively cause the box portion 56 to be restrained from movement as the box portion side of the sack is urged outwardly thereby automatically opening the bag. Thus, in the type of sack or bag illustrated, the sacks should be placed so that the box portions ts face forwardly. After the sacks or bags are placed in the dispenser as described, the hook 50 is disengaged -so that the sack advancing member 36 provides a pressure drive and yieldingly and frictionally holds the lower portions of the sacks or bags 42 against the stop member 38 and the friction pad 40.

It is believed that the operation of the dispenser is apparent from the above description.

By way of summary, after loading the dispenser in the manner indicated heretofore, the sacks are yieldingly and frictionally held at their lower portions and the forward ends successively emerge at the front of the device. By grasping the extending edge 54 of the sack 45, which must be the side on which the box portion thereof is folded, withdrawal thereof will automatically open the sack. The next sack is automatically brought into position to be withdrawn by the pressure feed from the bag advancing member 36 and the guide 44. withdrawn and the next succeeding bag brought into position.

While I have described a preferred embodiment of my dispenser in some detail, it is manifest that broadly my invention comprises a housing or casing to hold the sacks or bags and means to provide a pressure feed and to yieldingly and frictionally grip the lower portion of the sacks,

so that the latter will automatically open on withdrawal. The housing or casing may be of any desirable type of constructionand the pressure feed means may be actuated by tension springs or as illustrated in Figure 5 by compression or flatsprings 30a or in other manner known to the art. Moreover, the friction grip may be integral with the housing or the housing itself may provide sufficient friction to frictionally engage the box portion so that the latter is restrained on withdrawal of thebag thereby opening the bag, as shown in Figure 9 and indicated by the numeral 38a. It is manifest, however, that the friction stop and the friction pad are preferred. In placing the sacks in the dispenser the edge thereof to be grasped, normally the leading edge, should be the box portion sidev of This bag may then be 4 the sacks; otherwise, there is no requirement as to the manner of placing the sacks or bags in the dispenser.

If desired the pressure feed may be utilized to force the bags against the back of the housing. Such an arrangement may be utilized for particularly large sacks where the top of the housing may be open and the sacks withdrawn from the top of the device.

Figures 3, 7 and 8 illustrate a modification of the forward sto member 38. Here a transverse bar 50 is provided between side braces 24 providing an axle so that the member 38b may be pivotally secured thereto. In this modification the member 38b is forwardly bowed at 62 thereby providing a bearing 54 so that the former may readily pivot on pivot rod or axle St. The lower innerportion of the member 381) may be inwardly and horizontally turned to provide an ear or an ejector at of such width to preferably engage the bottoms of two sacks. Thus the forward sack will be in an advanced position and easily grasped, and when so withdrawn the member 38b will pivot on the axle til and will automatically bring the next succeeding sack into leading and forward position to be withdrawn. A stop member 68 is secured to the inner sides of the side members 24 to provide a stop for the member 38b. The configuration of member 381) is such that in combination with the feed pressure against the bottom of the sacks produced by the advancing member 36, the forward stop 3% will be brought back to its initial position as indicated in the drawing after a sack has been withdrawn. The ear 66 should be flush with the floor of the housing or casing in or with the top of the members 25, and, while not necessary, a spring means 81 may be utilized to aid in returning the forward stop member 38b to its initial position. All other parts are similar to the above described preferred form and it is believed that the operation of this modificationis apparent from the description. This modification is particularly adapted for large or stiff sacks or bags.

A still further modification of the forward stop member is illustrated in Figures 4, 5 and 6. Here the stop member 38c is secured to the forward transverse member 34 as in Figures 1 and 2. The upper portion at of member 380 is upwardly, and outwardly inclined and is provided with a longitudinal slot 12 to slidingly receive the depending pin 14 of the trip arm 16. The key or pin 14 is connected to the spring 18 as shown, the latter being secured to the lower forward housing support member 34. A longitudinalslot is provided in the lower ortion of the vertical face of member 38 which slidingly receives pin or key 82, the latter being connected to the spring 18 inany conventional manner such as by welding indicated by the reference numeral 19 a short distance from the bottom thereof.

The key 82 extends to and is integral with a lower ejector member 83 having a vertical face 84 which in turn is flush with the inner vertical face of the member 380. The slot '80 is recessed to receive the ejector face 84, and the lower portion of the latter is inwardly and horizontally turned to provide the ear 66c flush with the'top of the floor of the casing or housing It.

In operation of this modification, the ear'86 of the trip arm 16, which may be made of spring steel, will engage the box portion of the forward sack or bag 46, thus urging the trip armalong the slot 12. The bags usually open when'the trip arm 16 is approximately two-thirds'alongthe slot 12 by means of the tension of the spring 18 restraining the box ortion from upward movement. Inasmuch as the trip arm (6 is fashioned of spring steel, the box portions of the bags are readily released from the ear 8!} thus permitting removal of the bags from the dispenser without wedging or tearing the bags. If desired the upper end of the slot l2 may be so formed to provide raising of the ear This may be accomplished ward end of the slot I2, as better illustrated in Figure 5. As the spring it is tensioned, the lower ejector 83 will be raised along the slot 80 an amount the spring l8 stretches between the point it is joined thereto and the bottom of the spring and the car 660 will raise the next-succeeding sack into leading and forward position so that it may be readily grasped for withdrawal. In this modification the box portion of the sacks or bags must face forwardly so that that ear 86 will engage the box of the sack and open the same. The other parts of the dispenser are the same as the preferred form.

While this last scribed in connection with a single trap mechanism disposed at either side of the stop member, or a plurality thereof spaced thereon, as illustrated in Figure 6.

In stores where various sizes of sacks are used it may be desirable to have a single housing oontaining a plurality of dispensing compartments adapted to the size and. stiffness of the sacks as to which modification for opening the sack is to be utilized. While I have shown my dispenser connected to the nether side of a counter or like member it is manifest that it may be connected to walls and the like in any conventional manner or may be simply placed or secured on counters, floors and the like.

It seems manifest that if desired the sacks may be withdrawn by grasping the bottom of the sacks and restricting the movement of the side of the sack on which the box-portion of the sack is disposed, such usually being the leading edge. Referring to Figure 10, the latter may be secured in a bag dispenser by providing a perforation 9 in the upper portion of the box-side edge and providing a small rod 8 on which the sacks may be suspended through the perforations. sired the bags may be disposed with reference to Figure 11 the the box portion side of the bags being cemented to the blank 7, the whole to be inserted into the dispenser Hid having the depending inwardlyturned flanges E into which the blank I may be positioned. It is only necessary that the side of the bag on which the box-portion is disposed be restrained as the bag or sack is grasped at the bottom and withdrawn. Thus the bag is automatically opened as it is withdrawn.

Broadly my invention comprises means to restrain movement of the box-portion side of the bag and applying withdrawal force to a portion of such restrained side, a preferred embodiment comprising a housing or casing to hold a supply of sacks or bags and a combination pressure feed and frictional gripping means, which may be integral with the housing or casing, for the lower portion of the sacks or bags in order that the box portion of the sack or bag will be yieldingly r and frictionally restrained so that the sack or bag will open upon Withdrawal.
