1 0 all quiz-0m may concern:

Be it known that I, Cannes HOLLY, a citizen ot the United States, residing at Loch port, in the county oi. Niagara and State of New York, have invented certain new and useful Improvements in Box-Feeding Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to article feeding devices, and with respect to its more specific features to devices especially adapted for feeding small open paper boxes of rectangular shape.

One of the objects of the invention is the provision of a practical device to feed light paper boxes accurately and in sequence.

I Another object of the invention is the provision of an eiiicient device to deliver boxes successively onto a support or guideway and thereafter teed them one by one while in said guideway.

Another object of the invention is the provision of an etficient and practical device whcrewith a series of closely adjacent boxes in a guideway may be fed one by one and spaced from each other along said guide way.

Other objects will be in partobvious and in part pointed out hereinafter;

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinatter setf'torth, and the scope of the application of which will be indicated in the following claims.

Divided and this application filed Decem- Serial No. 488,450.

Fig. 8 is a cross section on the dotted line 8-8 F ig. 4;

Fig. 9 is a detail of a pawl shown in Fig. 4;

Fig. 10 is a cross-section of the guideway through the angle bars 2-, 2, and theframe 20, and

Fig. 11 is a diagrammatic View showing cooperative drivingdevices for different parts of a machine equipped with the invention.

This application is a division of an application filed January 16, 1911, Serial No. 602,862, to which reference may be made, such other application disclosing a complete box making machine equipped with the invention forming more especially the subject matter of the present application.

Referring to the prior application, previously made boxes, or bases, are placed open side down on a continuously moving belt 1 (Fig. 2) and are conducted to position oppositethe receiving end of a support, in the present instance, a guideway or channel formed by oppositely disposed angle bars2 spaced from each other so that certain box, orelement, feeding devices may enter from below between the angle bars and operate to feed the boxesalong such guideway. In the complete machine referred to, there is provided an oscillatory carriage, generally indicated by the numeral 3, the-lower portion of which in its lower position aligns with the end of the guideway formed bythe angle bars 2 and formsa part or extension of such guideway. Also when the carriage 3 is in its lower position it displaces a spring held stop a, which otherwise extends into the path of the boxes. Thus itwill be seen that when the carriage 3 is in its lower position, movement of the boxesalong the guideways 2 and through the carriage 3 may be readily eiiected. The subject matter of the present application has more especially to do with that aspect of the invention as it involves the mechanism for delivering the boxes to the guideway and feeding the same therethrough.

The numeral 5 indicates a rceiprocatory picker which operates transversely of the belt 1 and delivers boxes from said belt into the guidcway, suitable mechanism being provided for enabling the picker to return to position to feed succeedingboxes. As the picker operates the boxes are fed along in the guidewa one box shoving the other ahead of it. he numeral 6 indicates a slide which reciprocates on the frame of the machine and to which the picker is attached for operative movements, this slide being reciprocated through the instrumentality of a connecting rod 7, coupled to a crank disk 8 on a shaft 9 having a bevel gear 10 meshing with another bevel gear 11 on the shaft 12 intermittently driven through the instrumentality of mutilated

gears

13 and 14, the latter gear being mounted on a shaft 15 driven from a sultable part of the machine, as from a countershaft 16 initially driven from the main driving shaft 17, all as diagrammatically illustrated in Fig. 11.

The numeral 18 indicates a rod, in the present instance a finger-supporting rod, extending longitudinally of the path of the boxes in the guideway and pivoted at one end to a bracket 19 depending from the slide 6. Thus the rod 18 will be reciprocated lonitudinally of the ath of movement of the xes by the rotation of the crank disk 8, and will rest at certain intervals. At the inner end of the frame member or I-beam 20 is a plate 21 arranged transversely of the I-beam and longitudinally of the machine.

The numeral 22 indicates an opening in the plate 21 through which the boxes pass as they move along the guideway. On the side of the plate 21 opposite the I-beam, is provided a flat horizontally arranged plate 23 having an upstanding flange whereby it is secured to the plate 21 at the upper horizontal edge of the opening 22, and adjustably fastened to said plate so that they may be spaced apart a proper distance, are guiding plates 24 having flanges 25 to support the edges of the boxes. The plates and

flanges

24 and 25 form a part of the guideway with which the flanged jaws of the carriage 3 directly align to form a continuation of said guidewa In or er to feed the boxes along this end of the guideway, a pusher mechanism is provided. In the present embodiment the rod '18 forms a part of this pusher mechanism and lies immediately below the guideway formed by the plates 2 and, in the present embodiment, has two feed fingers, or ele ment engaging

members

26 and 27 attached thereto, one at the outer end and one at a distance from said end, said fingers being adapted to engage the inner face of a wall of a box and feed the same forwardly (to the left in Fig. 1) as the rod 18 moves in one direction. Secured to the plate 21 at the sides of the opening 22 therein are

frame pieces

28 and 29. The frame piece 28 supports a 1 vertically arranged plate 30 having a longitudinal horizontal extending reccss 31 on the wall of which is pivoted a switch 32 having a pin 33 passing through a curved slot in the plate 30 and engaged by a spring 34, which is so arranged as to yieldingly hold the switch upwardly against the upper horizontal face of the recess 31, which upper face provides a track to. guide the movement of the bar 18 and determine the plane of movement of the

fingers

26 and 27 in one direction of reciprocation of the bar 18. The switch 32 has an inclined face 35 and a face 36 continuous therewith, the lower wall of the recess 31 being inclined opposite the face 35 as at 37, and substantially parallel to said face when the switch is in upper position. On the op posite side of the pivot of the switch from the point thereof, the switch is provided with a curved portion 38 continuous with the face 36, continuing in a straight portion 39 to the point of the switch. The switch is pivoted at about the central portion of the vertical extent of the recess 31. Spaced from the lower portion of the plate 30 is the rod 40 and between the opposing face of said plate and rod a slot 41 is provided centrally beneath the guideway for the boxes. The

usher rod 18 nearits outer end, and in this instance between the

fingers

26 and 27, is provided with a depending lug 42, which in all positions of the pusher rod extends through the slot 41, serving as a guide for said rod. On the lateral face of the lug is secured a roller 43 which plays in the recess 31 between the switch 32 and the walls of said recess. The pusher rod 18 is yieldingly pressed upwardly toward the guideway for the boxes by devices hereinafter described. It will now be apparent that as the pusher rod 18 is reciprocated, the

fingers

26 and 27 will be moved back and forth longitudinally of the path of the boxes and in their forward movement will be guided in one plane by the straight upper horizontal wall of the recess 31, the yielding devices hereinafter referred to maintaining the roller 43 against the upper wall of said recess. As the pusher rod 1s moved forward the switch 32 is deflected against the resistance of the spring 34 and eventually the roller escapes the polnt of the switch and is received in a conforming opening 44 in the plate 30, whichfopening communicates with the recess 31. After the roller escapes the point of the switch the spring elevates the switch and when the pusher rod 18 moves in an opposite direction the face 39 of the switch causes the

fingers

26 and 27 to first move downwardly out of the path of the boxes, then rearwardly substantially horizontally, but in a different plane from that of their feed movement, and still out of the path of the boxes, and finally upwardly, the roller 43 following the curved portion 38 of the switch and eventually contacting with the upper horizontal wall of the recess 31, at which time, the fingers will again be in pushing position.

The piece28 which supports the switch mechanism for the pusher, extends for- Wardly beyond the switch mechanlsm and "Witlrthe piece 29 support a short downpushed into the portion of the guideway. formed by the channel bar by the front.

pusher finger 26 and supported therein by the shoulders 47. A pivoted gravity operating stop comprising a pawl 48 is provided at the upper portion of this guideivay, the tooth of the pawl projecting into the passageway throughthe channel a5 and having a cam surface 4L9 with which the boxes contact as they move past the same. The pawl is lifted by the boxes as they enter the channel and the boxes are prevented from retrograde movement by the tooth of the pawl.

The pusher rod lSis yieldingly pressed upwardly. by plunger 50 guided in an opening in a lug 51 on the plate 21 and passing through an opening inacross piece 52 supporteda substantial distance below the plate 21 on the rods 53, a spring 54 surrounding the plunger rod 50 and held between the crosspiece 52 and an adjustable collar 55 on said rod.

The box bodies are initially fed forwardly inthe guideway formed by the bars 2 by the picker mechanism, and eventually the foremost box arrives in the neighborhood of the discharge endof the guideway. Assuming the pusher rod 18 tohave been drawn rearwardly and upwardly to pushing or feeding position, the finger 27 will extend through the passageway between the walls 2, contact with the box body which is immediately in the rear of the one about to enter that portion of the guideway formed by -the'carriage 3, while the end finger 26 will assume a position beneath the box in the carriage portion of the guideway. This end finger willtake position immediately in the rear of and close to the inside face of the front wall of the box adjacent thereto, but the distance orspacebetween the

fingers

26 and 27 is such that when the finger 26 isin the position just referred to, the finger 27 is some distance in rear of the front wall of the box with which it is about to cooperate. As the pusher moves forwardly, the front finger 26 may immediately operate on the box to move it forwardly positively intothe channel plate 45, while the finger 27 is moving to the frontwall of the box immediately adj acent thereto. In this manner the foremost box is fed some distance forward before the rear finger 27 begins to push the box iminediatelyadjacentthereto. hen the finger 27 does engage the wall of its adjacent box it pushes thebox just ahead of it. and which, in the present v,embodime nt, isbetween, the boxes engaged by these fingers, into thecarriage. portion of the guideway. In this wise, not only is a mechanism provided which will feed the boxes along the support or guideway into a predetermined position in said guideway, but by having the feed fingers spacedapart a predetermined distance greater, than the length of ,a box, and in the present instance greater than the added lengths of two adjacent boxes, or elements, to be fed, the foremost boxmay be spaced, or moved away from the next succeeding box, and this latter feature may be utilized as desired, for instance, for drawing out a length of cord attached to the foremost box, as explained in the prior ,application above referred to, so that an automatically operating knife, relatively stationarily positioned, may sever the cord at a point remote from where said cord is connected to the box.

It will-be observed that the recessed plate 30 together with the switch 32 provides a trackway, substantially endless in character, to control the position of the rod '18 and therefore of the

fingers

26 and 27, transversely of the path of movement of the boxes. The upper wall of the recess 31 provides a track with which the roller 43 c0 operates and by which it is guidedon its feed movement, whereas the switch 32 defleets the rod away from said track in a direction opposite to that given the rod 18 by the plunger 50 which latter slidingly engages the rod 18. As the rod 18 moves to the left (Fig. 1) the boxes adjacent the dis charge end of the guideway are fed forwardly, and between the intervals of such successive

feeding movementsthe fingers

26 and 27 will be urged first positively out of the path of the boxes and then back into said path.

Viewing F 1, it will be perceived that the

fingers

26 and 27 arespaced apart a distance greater than the amplitude of reciprocation thereof, which latter is determined by that of the rod 18. The picker 5 delivers the boxes into the guideway formed by thewalls 2, one following another, with the boxes touching, or contiguous to each other therein. When the rod makes its advance move ment, the box in the carrier 3, and with the innerwall of which the finger 26 is in contact, is immediately fed, not only for a distance equal to its length so as to completely remove it from the carrier, this being a predetermined distance for thesize of the box but it is also fed an additional distance for a purpose already explained. On the other hand, the next succeeding box is fed a dis% tance to dispose it in. the carrier, this distance being at least equal to the predetermined distance just referred to, the boxes being of the same length. By making this distance between the

fingers

26 and 27 greater than the distance moved by the fingers infeedingflhe advance boxiis so moved as to space it from the next succeeding box, when they are originally practically contiguous in the guideway, but the same amount of movement of the finger 27 feeds the next succeeding box referred to only enough to place it in proper position in the carrier 3, and when the boxes are of equal length and touch each other in the guideway, this amount of movement is practically the same as the length of a box, and hence at least equalto the predetermined distance before referred to.

Thus by the above described construction are accomplished, among others, the objects hereinbefore referred to.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
