Original application filed February 18, 1913, SerialNo. 749,688. Divided and this application filed July 16, 1913. 7 Serial No. 779,258.

To all whom it may concern:

Be it known that I, ERNEST G. T1101? soniuor, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cutting and Conveying Mechanism, of which the following is a specification.

This invention relates to paper feeding, cutting and conveying mechanisms, particularly applicable to machines for Wrapping stick candy or like articles, such as disclosed in my co-pending application, filed Feb. 18, 1913, Serial Number 749,088, of which the present application is a division.

One object of the present invention is to provide means whereby the paper, to be used for wrapping the sticks of candy, may be fed in a continuous web and the individual wrappers eut automatically and deposited upon the conveyer to be conducted to the wrapping mechanism. 1

Another object is to provide a construe tion by which the wrappers may be cut with inclined edges so as to facilitate their wrapping about the sticks.

Still another object is to provide a simple and compact construction for the cutting and feeding mechanisms.

Still further objects and advantages will appear more fully from the detailed description and the novel features consisting in the construction and combination of parts will be particularly pointed out in the claims.

In the drawings illustrating this invention, Figure 1 is an elevation of the wrapping machine with portions cut away and other portions illustrated diagrammatically for the sake of clearness. Fig. 2 is a see tional plan view of the machine illustrating the angular arrangement of the cutting and feeding mechanisms. Fig. 3 is a section taken along line 3-3 of Fig. 2 Fig. 4 is a detail plan view illustrating the guide for the paper, the cutting mechanism and means for actuating the same. Fig. 5 is a fragmental detail view illustrating in perspective the paper guide, the fragment "being cut at line 5-5 of Fig. 4. Fig. 6 is an elevational detail view illustrating the cutting knives and the cam for operating the same. Fig. 7 is asection taken along line 7-7 of Fig. 6. Fig. 8 is a sectional plan, and Fig. 9 isan elevation illustrating in detail the gearing connection between the endless conveyer belt for the wrappers and the endless conveyer belt on which the wrapped sticks are de llvered. F ig. 10 is a detail View illustrating the paper feeding and gripping rolls.

The sticks of candy are fed from a hopper 10 to a revolvingdrum 11 having a series of recesses 12 in which each stick is deposited and conducted to the wrapping mechanism. The latter consists of a rotary carrier 13 having a plurality of wrapping devices 1 1 mounted thereon, each of which is adapted to receive a wrapper and to wrap the same about a stick. The drum 11 has ducts 15 formed therein which areconnected with some suitable suction device, and through the suction thus exerted, pick up the wrappers from the conveyor belt 16 and deposit the same at the proper'time in the wrapping devices upon the carrier 13. All

of this mechanism is described in detail and claimed in my co-pending application above referred to. Further description of the same in the present application is, therefore, deemed unnecessary.

I will now describe how the paper for the wrappers is fed continuously from a roll and is cut to the required length and shape and deposited upon the conveyer 16 by which it is conveyed into the drum 11.

Mounted preferably upon the side of the frame of the machine at a suitable point to the rear of the hopper is a bracket 66 carrying a roll of paper or similar wrapping material 67. The bracket isdisposed at an angle with reference to'themaehine, so as to feed the paper at an incline with reference to the longitudinal axis of the machine, for a purpose hereinafter to be described. The paper is fed in the form of a web 68 by a pair' of feed rolls 69 and 70 which grip the paper and feed it into a guide 71 which is disposed longitudinally of the paper reel. The feed roll 70 has a gripping surface 72 of some suitable yielding fric tion material such as rubber or the like disposed in the form ofa ridgeon the face of the roll. The opposing roll 69 has guide flanges 73 formed at each side to properly guide the material. The latter roll is suitably driven by a'trainof gearing. A suitable tension deviee is provided for the web, so as to maintain it in proper position to be led to the feed rolls. This tension device consists preferably of a lever 74 fulcrumed upon the bracket 66 and provided at one endfwith a roll 75 overwhich the paper .passes'in substantial alinement with the gripping point of the feed rolls 69 and 70. Atits other end, this lever'is engaged by ,impelling means such'as a rod 76 yieldably held. upward by a spring 77 abutting a lug 78through which the lower end of the rod passes. The feed rolls 69 and 70 are mounted in suitable brackets Y 9 and 80. From the latter-bracket preferably projects a hanger ESL supporting the outer extremity of. the guide71 into which the paper is conducted i from the feed rolls as previously described.

This guide is in the form of a plate having a slightly concave bottom 82 and upturned lateraledges 83. Theguide gradually converges in widthso as to rectify the paper in 7 case it should enter the same slightly out of proper alinement.

- After the paper leaves inthe proper lengths and conveyed to the drum 11 which takesjnp the individual Wrappers by means of itssuction devices and conducts them into the proper place withreference to the wrapping mechanism.

By reason' of the inclined mounting of the bracket, feed rolls and paper guide, the

. paper is fed at an'incline withreference to the length of the machine, so that the edges of thew'rappers maybe cut on an incline arm 86' of alever87,-fulcrumed upon fapin for the ends of the blade. 50

88, extending from a bracket 89. A suitable knife blade 90 is adjustably attached tothe lever 87 in' anyjdesiredmanner as by screws 91 passing through slots 92in the blade. Set screws 93*passingthrough the plate 94 formed onjthelever 87 constitute adjustable abutments against which the back of the blade may .be adjusted. Lugs 95 projecting downward from the plate constitute guides A spring 96 is connected tothe lever 87 and extends to a projection 97 formed on the frame and thus holds, theknjife .away from the paper. At every revolution of the cutter actuating shaft s41,1the knife 90 isfbrought down to out"; a'length of rapper. The opposing knife or. shear plate 981 is also adjusltably mounted in a socket plate 99 and is guided and adjusted by holding screws. 100 passing throughjfthe slots 01, the set screws 102 forming the abutments for the back of the blade; The plate 99 is 'attlached to the bracket89 to which, itfwijll be remembered, theknife lever is fulcrumed.

-As. will. be readily understood from the foregoing description, the paper is fed conthe guide, it is cut tinuously and is cut by the cutter knife while it isbeing fed. It is necessary, therefore, that the knife be given a movement in the direction of the feed of the paper while it is cutting the same. For this purpose, during the time that the knife is actuated, the latter together with the bracket 89 and the cutter actuating shaft are given a longitudinal motion in the direction of the motion of the paper. The bracket 89 is, therefore, loosely mounted upon the shaft 84 between two collars 103 fixed to the shaft. A pair of arms 104 project from each side of this bracket and are provided with eyes 10;) forming bearings extending over guide rods 106 attached to the frame of the machine. A disk 107 is fixed to the cutter shaft and is provided with a pair of diametrically opposite cam projections 108 in the path of which project rollers 109 suitably mounted upon brackets 110 secured to the frame. Each time that the shaft moves into the position for actuating the knife to shear off a portion of the paper, the cam projections 108 engage the rollers 109 and cause the shaft 84 to move longitudinally against the tension of a spring 111 disposed between a suitable abutment attached to the shaft and the adjacent side of the frame. The shaft in so moving longitudinally, carries with it the bracket 89 together with the cutting knives. It is clear that by means of the guide rods 106, the bracket is maintained in its proper horizontal position.

As has been previously explained, the bottom of the guide plate 71 in which the paper is guided as it approaches the cutter, is of concave contour and thus causes the paper to assume a corresponding curve as it approaches the knife. This formation of the paper stiffens it sufficiently so that a length sufficient for awrapper may extend past the knives without sagging down. To maintain this curve of the paper. the bracket 89 has attached thereto a curved guide 112 in alinement with the guide 71, and of a shape similar to the adjacent end of the latter. Also the edges of the knives 90 and 98 are correspondingly curved.

The conveyer 16 is driven from the gear 134 connected to the drum 11 through the intermediary of another gear 135 meshing with the gear 134 and fixed to a shaft 136 (Fig. 8) running across the width of the machine. 011 the opposite end of this shaft is mounted a gear 137 which meshes with a pinion 138 carried in a bracket 139 pivoted upon a shaft 136 and adjusted and clamped by a screw bolt 140 passing through a slot 141 formed in an arcuate extension 142 extending from the bracket. The latter may be adjusted so as to throw the pinion 138m mesh with another pinion 143 mounted upon the shaft 144 carrying a roll 145 by which the conveyer 16 is driven. Fixed upon the shaft 136 also is a pulley 1-16 carrying a belt 147 which drives another pulley 148 mounted upon shaft 149 carrying the roll 150 which drives the conveyer belt 150 upon which the wrapped candy sticks are discharged from the wrapping devices.

For driving the feed rolls and the cutting mechanism for the paper, the following gearing is provided: Fixed to the shaft 136 adjacent to the gear wheel 135 is a bevel 151 meshing with a corresponding bevel gear 152 fixed to a vertical shaft 153. At the lower end of this shaft is fixed another bevel gear 15 1 which meshes with a bevel pinion 155 fixed to a horizontal shaft 156 running to the end of the frame where it is suitably journaled in a bearing 157. Adjacent to this bearing another bevel pinion 158 is fixed to the shaft 156 meshing with a bevel gear 159 mounted upon a vertical shaft 160, at the upper end of which is mounted a bevel gear 161 meshing with a bevel gear 162 fixed to a horizontal'shaft 163 which runs obliquely across the frame. At its opposite end, the shaft 163 has a bevel gear 164; fixed thereto meshing with the bevel pinion 165 fixed on a vertical stub shaft mounted in a suitable bearing 166. At the upper end of this stub shaft is fixed another bevel pinion 167 meshing with a bevel gear 168 attached to the shaft upon which the feed roll 69 is mounted. Thus, the feed rolls are driven at a speed corresponding to the motion of the drum 11.

For driving the cutting mechanism, a gear 170 is attached to the shaft 163 meshing with a wide faced idler gear 171 mounted upon a pin 172 projecting from the frame, the latter gear meshing with a pinion 173 attached to the cutter actuating shaft 8 1. As the drum 11 rotates, it transmits its movement by the train of gearing above described to the cutter actuating shaft, thus actuating the cutter knives to shear off the proper size of wrappen By reason of the wide face of the idler 171. the longitudinal motion of the cutter actuating shaft 8% will not throw it out of'mesh with this gear.

It will thus be seen that I have provided a paper feeding and cutting device in which the paper is fed in a continuous web and is cut to the proper lengths by the cutting mechanism and deposited upon a conveyer, the feeding and cutting mechanisms being so arranged as to cut the wrappers with inclined edges, thus adapting the same to be wrapped readily about the sticks. The arrangement of the paper feed transversely of the frame renders the machine more compact and simplifies the connections for driving the cutting mechanism. The latter is certain in its operation and by reason of the traveling motion imparted to it in the direc tion of the feed of the paper, assurance is had that the edges of the wrappers are out clean and no wrinkling of the paper can take place. The novel means for guiding the paper alsoassures that the wrappers, after being cut, are properly deposited upon the conveyer.
