To all whom it may concerm v Be it known -that I, ALBERT M. PRIGE, a

1 citizen of the United States, residing at Elgin, in the county of Kane. and State of Illi nois, have invented certain new and useful 4 Improvements in Cutting Mechanism for Wrappin Machines,. of-which the following s a spec' cation.

ap lication for United States Letters Patent, erial Number 278,338, filed .by me Sept. 13, 1905 has for its subject-matter a -machine for wrapping sticks of chewing gum and'jlike. articles of uniform size, said machine comprising among other mechanism,

means for receiving a strlp of wrapping mater al, such as paper, from a roll, guiding 1t to the article to be wrapped, holding it thereon and cutting it into. proper size. This cutting mechanism forms the subject-matter piece. of gum of the present inve'ntion which is said application #278,338.

' In the description of this invention while a division of the article to be wrapped is designated as a 1 be readily understood it wi that this articleis merely used for the purpose-of illustration-and that any other farthe machine, if desired.

ticle of suitable form and size may be used In the accom anyin'g drawings which have illustrate only such portion of the complete machine as is necessarytothe present invention, Figure 1,- is'asectional view of art ofthe feeding wheel'showing the means or supplying the we per to said wheel and the means for proper yholding the wrapper thereon and cutting off the proper length, the parts being the positions assumed ust prior to the cl'itting operation. Fig. 2, is a I simila'av ew of the same parts in theposition there. is provided a suitable magazine in. which the pieces of gum are laced by the I operator fromwhich they are elivered, one

just after the cutting operation;

Inthe general arrangement of the machine at atime, to a continuously rotatin feederwheel having a number of receptacles in its periphery, each of the proper form andshape against :the feeder-whhel, until a predeterminejdfpoint is reached, when the cutting Patented Feb. 25, 9081-. I

mechanism operates, cutting off a proper length to'cover one piece. The ,inechanisms which-receive, conduct,.hold and sever the paper, under the general name of cutting mechanism forming the subject matterfof this invention, other parts will be only incidentally referred to "and not specifically described. y

r The feedi g Wheel 2 is mounted upon a shaft suitably .j ournaled in the framev of the machine and is provided with a rim 22 inwhich, at regular intervals are formed pockets or receptacles 23, These pockets coincide with thespokes 21-of the wheel 2, the spokes being hollow to-receive rods 24 .pro-

vided at; their outer ends with plungers 25" arranged within the' .pockets' With its plunger at its innermost positions, each pocket is of just sufficient depth to receive one piece of gum. On the inner. sideof each adapted to enga e under a ring 27 to hold the p'lungers in their inner positions, during the time the article is to be retained in the rod 24: is mounted a small roller 26 which is i I pocket, said ring being cut away at'a point chine (notshown).

Each plunger has a small pin 29 secured to its face w 'ch pierces the gum andipre reached later on in the operation ofthe 'Inaso Y vents its displacement when otherwise not i sup or-ted. i r

' o a rigid ortion of the machine is secured a guard 37 w 'ch extends partially around the feeder wheel 2 andprevents the pieces of gum from beingthrown' out of the pockets 23 by I centrifugal force while the feeder-Wheel rotates, the direction of its rotation being to the left, said guard 37 being cut away, at a suitablepoint (not shown) to admit of the passage of a strip of paper 39 from a suitably supported rollor spool40. The paper is then carried around with the feeder wheel 2' and between it and the guard 37, coveringthe pieces of the gum in the pockets. The guard I i 37 serves the double purpose of retaining the pieces-of gum in the poo paper against the rim of the feeder-wheel, its

lower end being provided with a flexible :ets and holding the s ring like extension 44: which lies between t e feeder wheel 2 and a roller 45, mounted on a shaft 47. The main central zone of this roller runs in contact with the extension 44 of the guard 37, while rubber collars 46, one

v which bears against the wheel 2 and causes at. the same time around each end of the roller, bear upon the i the paper-39 to move therewith [at their oint of tangency, thus holding the paper firmly at. both ends of the strip to be cut off between the roller 45 and the roller 54,

ermitti'ng it to constantly move forwar with thefeed-wheel 2.

Knives

56 and 57, are mounted upon opposite sides of the roller 54 alternately adapted to enter grooves 58 in the feed-wheel 2/ The paper being held firmly on either side of'the grooves 58, is punctured by a series of .fed from the roll '39 may points comprising saw-like edges for the nives and as these points are pushed farther through the paper, the puncturesv are enlarged until they merge into each other thus completely severing the paper. I

In order that the forward end of the paper not be carried downward by the roller 54, but shall be passed onward with the Wheel 2 above a guide 59 secured to the frame of the machine, the roller 54 is provided with four plungers, 60, one pair of which are arranged upon each side thereof. The plunger-s are held in their positions by springs 61 arranged. between their heads 62 and screw-plugs 63 by which the springs are confined. As the roller 54 revolves each plunger engages the feeder-wheel 2, the spring 62 permits the plunger to move back but at the same time holding it against the wheel. -The plunger moves inwardly, as it engages the wheel 2 but after it passes the tangential point it again moves outwardly, holding the forward end of the paper against the wheel (see Fig. 2) until the paper passes over the guide 59. attached to it a spring 64. which extends along the wheel 2, almost toa point where the pieces of gum are delivered from the feeder-wheel and serves the double purpose of preventing the gum from dropping from "the pockets in the wheel '3, and preventing the severed portions of the paper (or blank) from adhering to and becoming rolled up on a roller (55 placed adjacent to the wheel. This roller is col'istructvd similar to the re ler 45, that is, with two resilient collars between which thesprin -gm is adapted to lie and rests against the feeding-nlmcl 3, at a point a little in the rear of the tangential point where the feeding wheel dcllvcrs the gum to a receiving wheel, (not shown) and aids m advancing the cut paper blank along until it, with the gum, is tlGllYOI'Ltl from the feeder-wheel '3.
