GE FORMING AND POSITIONING APPARATUS.

Application led May 23,

To all whom t may concern:

Be it known that we, MATHIAS FoGDE vand LAWRENCE P. SOUTHWICK, respectively a subject of the Government of Russia anda citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented new and useful Improvements in Charge Forming and Positioning Apparatus, of which the following is a specification.

This invention relates to improvements in charge forming and positioning apparatus.. and pertains more particularly to apparatus operative to automatically produce a charge of'multi-unit character for work-performing apparatus.

While the invention is not limited in use to charges of multi-unit character-being applicable for use in connection with single units-it is especially adapted for multiunit service and particularly where the operations of the work-performing apparatusv are of the nature of gang operations. Nor is the invention limited to use in connection with any particular type 0f workperforming apparatus or character of unit.

For the purposeof explaining the invention, however, we have shown it as employed in the production of charges formed of individual packages, such for instance as cigarette packages, the work to be performed on the charge being that of applying the usual revenue stamp to each ofthe units of the charge. For instance, the apparatus-may be employed in producing the-charges for the ap aratus disclosed inthe patent granted to us Bctober 23, 1917, No. 1,244,438, an apparatus designed to locate a succession of units-forming a charge-at redetermined points relative t0 stamp-aplilying mechanism, the operation of which serves to ,pro-

vide a stamp individually to each of the 5 units of the charge, disclosure of the patent being designed to employ a charge of ten units to which a corresponding number of stamps are applied concurrently.

As will be understood, the presentation of a charge formed 'of a number of units of this type -to a mechanism operative concurrently on all of the units requires that the units be presented concurrently rather than successively in order that the apparatus operation be not unduly delayed; in

Specification of Letters Patent.

I Patented Dec. 27, 1921. 1919. -Serial No. 299,286.

other words, that the units of the charge be presented 'in a manner similar to that of a single unit, in order that the normal cycle of operation of the work-performing apparatus may not. be effected in such manner as to decrease the 'capacity of the apparatus. Obviously, these conditions present a number of lproblems of maintaining the supply of units for the formation of charges, since each charge takes from the supply a number of units equal to the number -contained in the charge-ten, in the partlcular apparatus referred to.

In addition, units of the type indicatedlcigarette boxes for instanceare of dimensions such as to make it more or less dificult to maintain the supply owing to the space requirements Where the attempt is made to position each unit in a charge in such manner as 'to permit the application of the stamp onto an end of the uni* and especially where .the stamp extends onto both sides of the unit when applied, an arrangement which practically requires that the unit be stood on an end during the stamp applying operation. And the diiiculties present will be further` appreciated from the fact that stamping mechanism of vthis general type has a capacity such as will take care of the product of a number of machines operative to produce the supply itself.

The present invention is designed to meet these problems and to make possible the forming and positioning of a multi-unit charge at the presenting mechanism of the work-performing apparatus in a simple and efficient manner 4and in such a way as to permit the supply to be maintained without the use of special care or expert assistance.

These ends are obtained by providing the supply in the form of superposed rows of units arranged in flatwise contact, the units having their direction of length extending more or less horizontal with one end in advance, each rofw containing a number of -units corresponding to the number adapted onto the units previously located in the charge reservoir.

rllhe charge reservoir is located relative to a suitable presenting mechanism in such way that advance of the lower row of the reservoir carries the units of that row in the direction 'of the position of the presenting means, and the structure is so arranged that each unit is shifted from the horizontal to the vertical during this advance movement, this being provided by what may be considered a stage operation, although the mechanism employed produces the two-stage operation during a single cycle of its movement. The mechanism thus locates all ofthe units in their proper positions relative to each other, so that the presenting mechanism can advance them bodily and concurrently as a charge to the work-performing apparatus. To this and other ends, the nature of which will be readilyunderstood as the invention is hereinafter disclosed, said invention consists in the improved construction and combination of parts hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out inthe appended claims.

lln the accompanying drawings, in which similar reference characters represent similar parts in each of the views, A

Figure l is a vertical section taken through a simple form of apparatus adapted for use for the purpose indicated, the view showing the parts at an intermediate stage of the general operation.

Fig. 2 is a similar view showing the parts in a different position.

Fig. 3 is a sectional plan view, the section plane being just above and parallel to the plunger 13. Fig. 4 is a perspective view of a filling tray.

Fig. 5 is a fragmentary perspective section of the unit advancing element.

A indicates a frame element which may be individual to the structure of the present inpreferred, however, to have a length suffivention, but which is preferably a part of the general frame work of the work-performing apparatus, the frame element having suitable guides on its upper face adapted to control the movement of a presenting element a which may be of any suitable design and which may include a vertically extending finger or other element a. Member a may, for instance, be in the form of an endless belt intermittently driven with a suitable number of elements a properly positioned thereon, or said member may be inv on more than a single plane on a vertical section of the wall, the upper portion of the wall, indicated at 11a, being shown as inclined outwardly-relative to the major portion of the remainder of the wall which eX- tends substantially in a vertical plane.

rllhe reservoir for the units is indicated at 12 being supported on frame A in suitable manner and preferably arranged slightly inclined to the vertical, the upper end projecting forward. The frame of the reservoir may be of any' suitable structural formation with the front wall closed and the rear wall open at a point removed from-thc bottom of the reservoir, the latter having a suitable plate 121L secured at the rear at the bottom of the reservoir so that this lplate and the front wall will provide a chute-like formation at the bottom of the reservoir and of a depth suiiicient to accommodate several rows-as for instance, four-of the units. The bottom of the receptacle is provided by a plate 12b, and both the front and the rear walls of the reservoir are cut away adjacent plate 12b, a distance substantially equal to or slightly in excess of the thickness of a unit, as shown for instance in Fig. 2.

Plate 12b extends forwardly beyond the face of the reservoir and to a position adjacent wall 11, the upper face of the plate being preferably a slight distance above the top planeV of said wall, thus providing a support for an advancing unit and at the same time permitting the delivery of the unit from the plate onto the inclined face 11a 'of the wall. The openings in the front and rear walls of the ,reservoir have .a length not less than the total length of the number of units which are to be concurrently delivered.

As heretofore set forth, the charge is .formed by advancing the lower row of units from the reservoir, and this action -is' obtained by the use of an element 13-which may be considered as a plunger-and which may be of any desired construction, it being cient to provide a face active on each of the units of the lower row. lin the particular structure disclosed, this element is shown as in the 'form of a plate, the advance edge of which is preferably inclined rearwardly toward the top plane of the plate; this inclination may be provided by a straight or a curved surface as may -be found desirable, the arrangement being preferably such, however, that a lower portion o f the plate be active in advancing the units, tl1is arrangement being preferred for apurpose presently described. The plate may be mounted in any suitable manner as, for instance, in guides 12, and is adapted to be reciprocated in the direction of advance of the units. This reciprocating action may be provided in anysuitable manner, the drawings indiamount of projection has reached a point cating a suitable member 14 secured to the under face of the plate 13 and mounted on one or more guides 15. Member 14 is provided with an elongated slot V16 within which a'projection-which may be in the for'm of a roller 16a-carried by an `arm 17 operates,

said arm being carried by a shaft 17.a ro-V tatable in suitable manner from a suitable source. As shaft 17a' rotates, the pivotal movement of arm 17 causes member 13 to reciprocate back and forth over the top of plate 12b.

Fig. 2 indicates the position of member 13 at the beginning of itsQadvancin'g movement, it being seen that the advance portion of said member contacts with each of the units contained in the lower row of the reservoir; while but a portion of the member is in contact with the unit, it will be understood that the latter will be advanced in a straight path by reason of the fact that the superposed rows will tend to prevent the units of the lower rows of being raised from od of plate 121?. Therefore, as member 13 advances, the lower row of units is advanced correspondingly, the result being that lthe units will be advanced to project beyond the forward face of plate 12", and when the where the greater portion of the weight of a unit is unsupported by plate 12b, the preponderance of weight will cause each unit to tend to fallofl' of the plate. This falling off action is permitted by reason of the particular configuration of the advance facel -of member 13, it being readily understood that the receding face formation will freely permit the rear end of the unit to shift vertically at this time although member 13 is continuing its advancing movement. As a result, the units change their direction from the approximate horizontal to the inclined position shown in full lines in Fig. 1, restin upon the inclined face 11a, and being he d from dropping into vertical position by reason of contact with the inner face of wall 10 on the opposite side of the trough.

As, however, member 13 continues its ad- Vance, the advance face of the member againA becomes active on the canted units and pushes the rear portionsv of the vunits forwardly` by reason of Contact with the under side` of the unit, the result being that a point 4is reached where the support providedv by wall 10 becomes ineffective and the` units drop onto the positioning element a with the direction of length of the unit -extending vertically as in dotted lines in Fig. 1. i

While these movements of the unit have served to change its position from the approximate horizontal to the vertical, the movements'have all been in the same vertical plane, with the result that the close relation of adjacent units in the reservoir is maintained when deliveredto the presenting elegment, so that -fnger af" may be in close proximity 'to the path of travel of positioned the unit with which it contacts during the presenting .operation without liabillty of preventing the free positioning of the unit.

Hence, the positions of the units relative to each other is practically maintained and assurance will be had that the units ofthe charge will be located in their proper positions in the work-performing apparatus by the advancing movementsof the presenting mechanism.

As will be vreadily understood, the advance of member'l places it as the temporary support of the remainder of. the` voir, the capacity conditions practically re-k quiring that more than a singleoperator will be required to maintain the supply within the reservoir.

To meet this condition, we prefer to employ a filling tray, such vfor instance, as is shown in Fig. 4, 1n whicha shallow tray 18 is employed, this tray havlng dlmenslons to receive in rows the number of units con' tained in a row. of the reservoir and having a suitable height suflicent to permit of the stacking up of a considerable number of rows. The tray is provided with a false bottom 19 against which an end of each unit is stacked, and the member is also preferably provided with aprojection 18a at its lower front edge,

'this' projection being ada ted to seat in recess 12*i of plate 12, y

as s own indotted linesin Figzl, the proj ection and recess operating to properly .lo- Acate the open front vof the -filling tray with respect to the rear open face of the reservoir, the result being that when so posi@ tioned, the false -bottom can be advanced and thus locate the rows of the filling' tray in their pro r positions in the reservoir, 1t being readill); lower row is theone removed, it is neces sary .only to add succeeding rows at the top.

Since there is no expertness required in stacking up the units in the filling tray,- it will, be readily understood that cheap labor may be employed for this particular purpose and several'trays may be in use concurrently by dierent laborers in' this stacking up operation, thus maintaining the sup- 'understood that since the.

ply of units in the reservoir without attempting to produce the individual stacking directly in the reservoir itself..

As will be apparent, an apparatus such as disclosed herein, when utilized in connection with work-performing apparatus adapted to operate on'a multiplicity of units concurrently, provides for high capacity conditions even though the work-performing apparatus is operative at comparatively low speed. For instance, if the work-performing apparatus is operating under capacity conditions of 40 operations per minute, it will be readily understood that the actual capacity is 400 per minute, and under such conditions thel question of maintenance of supply is a conslderable problem because of thel inability of a number of operatives to work concurrently in connection with the reservoir. l

As will be readily understood, the invention is of simple character and is of few parts; therefore, the cost of construction and maintenance is relatively small. At the same time, the simplicity is such as to reduce liability of derangement, so that assurance is practically had of continuous operation with each charge properly formed and located relative to the presenting mechanism in a, simple and eiiicient manner.

While plate 12b and element 13 may be of any desired construction, we prefer to employ an arrangement such as is disclosed in the drawings, in which the upper face of plate 12b is provided with a plurality of grooves 12 which are adapted to receive complemental tongues 13a; since the grooves extend to the top plane of the plate, it will .be understood that the actual supporting surface for the units is in the form of spaced faces, thusreducing the amount of friction between the units and the plate in the advancing movement of the units; obviously, the plurality of tongues and grooves will tend to prevent any canting action of element 13 as .the latter is reciprocating, and hence there is less likelihood of any binding of the element to aect the elements oper ation.

In addition, we prefer to provide the advance face of element 13 with a gene-ral configuration such as is indicated in Fig. '5. As' shown, this face is inclined rearwardly from an intermediate point, while that portion below such point extends' on dierent planes to form what may be termed two noses 13b and 13, the latter proiecting in advance of the former, but being located as a part of the tongue formation 13a.

As will be understood, the part ofelement 13 which is normally active inthe advanc- `ing of the unit is that located above the top plane of the tongues, and this includes portions of both of the noses.y When, however, element 13 advances toa point where the Leones? tongues begin 'to pass out of the advance ends of the grooves, the several noses 13 become effective in producing the falling oif action should this action havebeen delayed for any reason during the advancing movement. Normally the falling 0H' action takes place without bringing the tongue portions of nose 13 into action, but this nose, being located on a lower plane than the active porthat the particular construction and viewsdisclosed are more or less illustrative, and that changes or modifications therein may be found desirable or essential to meet the exigencias of use; therefore, we desire to be understood as reserving the right to make any or all such changes or modifications therein asv may be found desirable or necessary inso far as the same may fall within the spirit and scope ofthe invention as expressed in the accompanying claims when broadly construed. y
