Serial N0. 356,807.

To all whom it may concern: Be it known that I, ALBERT M. PRICE, a citizen of the United States, residing at Elgin, in the county of Kane and State of Illi- 5' nois, have invented certain new and useful Improvements in Feeding Mechanism for Wrappin -Machines, of which-the following is a specii cation.

An ap lication for United States Letters Patent, erial Number 278,338, filed by me September 13, 1905 has for its subject matter a machine for wrappin sticks of chewing gum and like articles uniform'rsize, said machine comprising among other mechanism, a magazine to receive the blocks, sticks or other articles to be wrapped, means for transferring said articles to a feeder wheel, a magazinefor holding a quantity of wrappers previously out to the proper size, and means for feeding the outer one of these wrappers to the proper positions to envelop the articlessingly as they are delivered from the feeder wheel to a receiving wheel. This ast named wrapper-feeding mechanism 5 forms the subject-matter of the present application which is a division of said application #278,338.

In the description of this invention while the article to be wrapped is designated a piece of gum it will be readily understood that this article is merely used for the purpose of illustration and that any article of suitable form and size may be used in the machine if desired.

s In the accom anying drawings in which I have illustrate only such portion of the complete machine as is necessary to a proper understanding of the present invention, Figure 1, is a view in side elevation of that part of the machine embodying the feeding mechanism, Fig. 2, is a View in side elevation showing substantially the same parts, Fig. 3,

Fig. 9, is a partial section on the Fig. 8, is

The mechanism forming the subject of the present invention is arranged at the lower rear end of the machine and is adapted to hold a number of. wrappers which have been previously cut to the size desired to be, used in the wrapping and deliver them one at a time to the receiving-Wheel. This mechanism comprises a magazine 77 having a bottom channel 78, formed therein," in which is mounted a screw-threaded shaft 79, journaled at its forward end in the journal bearing 80, and near its rear end in the journal bearing 81 and u on the rear end of which is mounted a suita le bevel-pinionv 82, and a crank-arm 83. This shaft engages in a thread cut in the lower portion 84 of a follower 85, and serves to advance the latter to move the mass of wra ers into engagement with frictional feed-rol ers 86 (Fig. 6) which are mounted upon a shaft 87, carried in journal bearin s 88 and 89, (Fig. 8) formed upon the ends of a yoke 90. The yoke is rovidech with two arms 90 formed integra with a sleeve 91, which is mounted upon a stud 92, which is in turn suitably secured to the frame 1, by a nut 93. The forward end of the magazine is mounted by means of the downwardly projecting portions 94 upon the ho1;,

low sleeve 91 of the yoke 90 and is held in such position by caps 95. The yoke 90 is mounted so that it can turn-freely on the stud 92 and within its bearings formed in the projections 94 of the wrapper magazine. A rearwardly extending arm 96 is rigidly mounted upon the sleeve 91 of the yoke and is adapted to engage a lug 97 mounted on the bottom of the magazine (Figs. 1 and 3). A pin extends from the arm 96 through the lug 97, and is providedon its underside with a coiled spring 99, and a thumb-nut 100 for adjusting the tension of the spring. By this means, the rollers 86 aremaintained in engagement with the paper with suflicient.pressure to cause them to pull the wrappers off, one at a time, from the front of the mass of paper as the rollers revolve. The shaft 87 is drlven by a shaft 101 through the medium of of a shaft 102, having at each end thereof a universal coupling. The shaft 101 has mounted thereon apinion 103, (Figs. 2 and 11) which meshes with a gear 104:, mounted on a shaft 105, on the other end of which is mounted a ear 106, meshing with the gear 72. The ro lers 86 have their surfaces com posed partly of rubber or other material and partly of a smooth non-adhesive material (Figs. 3 and 6) and their circumferences are so pro ortioned to the length ofthe wrapper that t e rear end of the wrapper will,as itis removed, come in contact with the non-adhesive portion only. By this construction, the next-sheet will not be started as soon asthe preceding sheet is removed,xbut only when the rubber or frictional surface comes in contact with it. It is a well known fact that when an effort is made to remove the first of a plurality of sheets of paper by frictional means bearing against the surface of the first sheet, two or more sheets will, in all probability, be removed, unless some means is holding all but the first sheet.

In my present invention I provide such means in the form of a needle 107, which is mounted at the forward end of the magazine 77, and against which the sheets of paper or wrappers are forced by the follower 85. This needle is of sufficient length to extend through a number of the sheets and puncture them a slight distance from the lowered e. While the friction of'the roller against t e first sheet is sufficient not only to overcome the resistance of the friction between the first and second sheets, but also to tear out the small portion necessary to release the sheet from the needle, the friction between the first and. second sheet would not be sufiicient to overcome the friction between the second and third sheets and also to tear'the second sheet from the needle. This is due to the fact that the frictions pull o'f',the rubber against paper is gicaier than that of paper against paper. itlhas been found, however, that if astationary needle is used, thepoint of the needle as it is forced through one sheet into the next tends to draw the fine vegetable fibers of which the paper iscomposed, into the perforation which is being made in the second sheet. These fibers are apparently carried by the point of the needlefrom one sheet to the next until the needle becomes clogged and is prevented from fulfilling its function. In this device however the needle is mounted upon a small rotating shaft 108, (Figs. {S and 7) supported in a journal 109 and provided with a bevel-gear 110, (Figs. 6 8, and 11) which is .a'dapted to mesh with a beveled gear 111 mounted upon the end of a shaft 112, connected with and driven by the shaft 105, through the medium of a driving rod- 113, (Fi 11), and the universal couplihgs 114 and 115, one at each 11(l, r0- the rod 113. By this means the needle is retatedru'lhis causes its point constantly to provided for.

and thereby advance the follower 85, the

following mechanism is provided. A rod I 116 (see Figs. 3 and 4) is provided at one end with a collar 117, mounted upon an eccentric 118, carried by a shaft 47. Theopposite end of the rod 116 is slotted, as at 119, whereby it will fitover a shaft 120, of a bevel-gear 121 and be supported thereb The end of this rod 116 is provided with an upwardly extending proj ection 122, on which is pivotally mo unte a pawl 123 (shown more particularly in Fig. 5) adapted to engage the teeth on a notched wheel 124, on the shaft 120. As the rod 116 is reciprocated by the eccentric 118, it reciprocates the pawl, and as the pawlmoves forward, it rotates the notched wheel 124 and therewith the bevelgear 121, which, in turn, rotates the bevelgear 82 and the screw-threaded shaft 79.

As the sheets of paper constituting the outer wrappers vary in thickness, it is impossible to arrange the itch of the screwthread on the shaft, so t at it will feed the follower 85 forward exactly the thickness of one sheet of paper for every reciprocation of the rod 116. It is not even possible to get this mechanism to average correctly for any given length of time, as different lots of paper will average a different thickness to the a sheet. For this reason the pitch of the screw on the shaft 79 is made approximately twice as great as would be necessary were it actuated by each reciprocation of the rod 116, and the following regulating mechanism is provided. A rod 125 is connected to the yo e 90 byan arm 126 (Fig. 8) and at its opposite end is provided with a slot 127 (Fig. 4) which engages over a circular projection 128, mounted upon the pawl 123. A hole 130 .in the pawl123 (Fig. 5) is made oblong to enable it to have a slight reciprocating motion on a screw 129, on which the pawl is pivoted. A coiled spring is mounted in the hole .130, and held in position b screw 131, so that normally the pawl is he d rearwardly against the screw 129. When the mass of wrappers is carried forward by the,

follower 85, it bears against the rollers 86 and as the pressure increases, the rollers 86, together with the yoke 90, are pressed forward in opposition to the tension of the spring 99. The yoke 90 carries forward the rod 125 and when this rod is drawn forward to such an extent that it intercepts the back ward motion of the pawl 12 at the rear end of the stroke of the rod 116, the pawl 123 will fail to enga e the next consecutive tooth of the whee -=1%24,-asshown in Fig. 4.'

former application.

ssnosa By this arrangement the rotation of the toothed wheel, 124 is intermittent and only occurs when the tension of the paper becomes slightly less than desired, and it becomes necessary to move the follower 85 forward slightly.

At; 132 is shown the continuously rotating receiving-wheel which is mounted upon the shaft l33 driven bythe gear 72. The construction of and mode of operation of this re ceiving-wheel are more fully described in my As the wrappers leave the feed-rollers 86, it is necessary that some means he provided to guide and hold the same upon the receiving-wheel 132, until the gum is delivered thereto. Mounted upon the outer end of the stud 92, upon which is carried the yoke 90, is an arm 134 (Fig. 1) which carries a. frame 135, within which are supported suitable resilient rollers 136 each adapted to bear against the periphery of the receiving wheel 132, and hold the paper wrappers thereon. The frame 135 comprises a pair of sides 137 and 138 (Figs. 6 and 10) having backwardly extending tail-pieces 139 at their lower ends and between which are mounted rollers 136. These rollers bear upon the periphery of the receiving Wheel 132, and as each paper wrapper is carried 1 p by the feed-rollers 86 the upper edge thereof is guided by the tail-pieces 139 and the aper passes under the rollers 136 and is he (1 by them upon the periphery of the receivingwhcel.
