rllhis invention relates to wrapping machines and has .particular reference to mal Aless series .of pushers each of which is designed to push a leaf in to position to be operated uponvby wrapping mechanism. The said slideway and base member are at an angle to each other, theV latter having side walls to guide the loaves as they are pushed in.

In machines of this character, it sometimes happens that a loaf arrives from the slideway on the outer: portion ofthe base member of the passageway leading in to the machine, more or less aslrew, so that when a pusher engages such loaf and starts it along said passageway, the forward end of the loaf contacts with the apex of the angle where the slidcway joins the said passageway. The result is that the continued movement of the pusher crushes the loaf. Then it becomes necessary to stop the machine, either manual- 1y or automatically, to remove the damaged article. This adds to the expense of employing' such wrapping machines because of not only the loss of some damaged articles'but also the time required to remove suoli articles and start the machine again.

The object ofv the present invention is to provide such machines with means which will automatically prevent the stoppage of, and damage to, articles on their way from the slideway or first port-ion of the angular passageway to the second portion or guideway along which the pushers travel. In accordance with said invention, the said means comprises` a wall member at the apex of the angle, which `wall member travels faster than thc speed of advance of a pusher, so as to draw a loaf that is somewhat askew away from the pusher andvstart it correctly along i the guideway into the machine.

of the machine `as is necessary to an understanding of the present invention. y

liigure 2 is ya diagrammatic plan view of a modification in structure.

Referring first to Figure 1, portion of the frame cf the machine is indicated at 40. it L12 and i3 are represented the lower end portions o-f the .inclined e'ravit slidewa for the es y loaifes. Normally each` loaf arrives against a stop wall la at the far side of thebase member l5 of the ,auideway along,` which the loaves are pushed in to the machine to posi tien to be assembled with wrapping paper. The inner side of said guideway consists of a wall plate 46. @ne ofseries of pushers 48 is illustrated. carried by an endless chain i9 carried by sprockets one vof which is illustrated as carried by a driven shaft 51. As se far described, the parts are supposed to be the same as the similarly indicated parts in Letters Patent No. 1,412,754 hereinbefore referred to.l Reference letters instead of numerals are employed herein to designate the features of the present invention.

1 arried by the shaft 51 is a pulley a connected by a. belt Y) with a small pulley c secured to the lower end of a vertical spindle .'Z suitably mounted in the frame ofthe ma- Said series of pushers are v ing down the rods Ll2 between the side kbars ---l arrives cn the base d5 not squared up against the stop wall le but somewhat aslrew illustrated by the full lines in Figure 1,' then the moment that a pusher 48 engages its rear end its front end is moved against the periphery of the roll c which latter, ro-

tating` at sufficient speed in the direction ofk the arrow, swings the front end of the'loaf to or toward the dotted line position so that the pusher can cause it to travel smoothly along between the walls 44, 46, and in to be wrapped.

Instead of employing a roll the periphery of which acts on the loaf as described, we may employ a belt as indicated diagrammatically at g5 in Figure 2; Such belt is illustrated as extending around the roll c and around pulleys 7L, k1, 7b2, so that such belt may not only act in the saine manner as has been described, but may also act onone end of a loaf a? near the lower end of the slide way 42 to increase the tendency of said loaf to reach the stop wall 44, and may also act on'the side of a loaf ai entering the machine to guide it against the wall plate 46.

Having now described our invention, we claim:

1. In a wrapping machine having an angular passageway .for the articles to be wrapped, a `travelling wall member at the inner apex of the angular passageway to facilitate movement of the articles past said angle, and means for causing said articles to move singly toward and past said travelling wall member.

2. In a wrapping machine having an angular passageway for the articles to be wrapped, a travelling wall member at the inner apex of the angular passageway, and means for pushing the articles along through the second portion of said angular passageway.

3. In a wrapping machine having an angular passageway for the articles to be wrapped, a travelling wall member at the apex of thev angle, and means for pushing the articles along singly through the second portion of said angular passageway to start it in a dieren-t direction of movement, means being provided for causing said trav- @lling wall member to movey at a speed higher than the speed of movement of the pushing means; Y e

e. In a machine having a guideway and means for pushing articles along said guideway, an inclined slideway at an angle to the said guideway for delivering articles onto the said guideway, and a travelling friction member in position to straighten out an article that arrives askew on the said guideway.

In testimony whereof we have aixed our signatures.
