Application filed February 7, 1905. Serial No. 244,608.

To all whom it may concern:

Be it known that I, AUGUsTE BLANO,1L citizen of the Republic of Switzerland, residing in St. Croix, Switzerland, have inve .ed certain new and usefulImprovements in Machines for Wrapping Chocolate Tablets or Similar Articles, of which the following is a specification.

This invention relates to a machine for wrapping up chocolate or other tablets or other articles of similar shape in a suitable wrapper, such as paper or tin-foil.

Among the objects of the invention is the provision of a machine of this type embodylng improved wrap ing devices and improved means for feeding the sheets of wrapping material to such wrapping devices.

The invention also aims to provide improved means for feeding the tablets or other articles to the wrapping devices.

A further object of the invention is to improve the general construction and increase the efficiency and capacity of machines of this type.

With these and other ends in view the invention consists in the novel features, combinations, and arrangements of parts to be hereinafter described and finally recited in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a machine constructed in accordance with the invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a top plan view. Fig. 4 is a vertical transverse section taken on the line A B, Fig. 1. Figs. 5 and 6 are vertical longitudinal sections of the upper portion of the machine, showing two different positions of the parts; and Fig. 7 is a vertical transverse section on the line C D, Fig. 1. V

Similar characters of reference denote corresponding parts throughout the several views.

In the drawings, A indicates the frame or table of the machine, which carries at one side bevel-gears 1 in operative connection with a worm 2, meshing with worn1-gear 4, which is secured to a shaft 3, extending transversely of said frame or table and journaled in the sides thereof. At one side of the machine the shaft 3 is provided with a gear 5, which drives through the intermediate gearing of a wheel- 6 a wheel 8, secured to a second transversely-extending shaft 7, ournaled in the sides of the table A above the shaft 3, as shown. The shaft 7 is provided at both ends with a crank 9, connected by links 10 to rocking levers 11, pivoted intermcdiately to the sides of the frame. Thc rocking levers 11 are connected by cranks 12 to the side members 1000f a carriage (1 which is guided in ways 12', extending longitudinally of the table top or bed 13 at either side of the machine. The carriage a cmbodlcs n cross-bar 14, which connects the side members and carries a wrapper gripping and feeding device 1), including a presscr-plutc 16, provided with a stop 15. Above the plate 16 and disposed parallel to the same is a gripper-bar 17, covered with elastic materialsuch, for instance, as rubber--and connected by rods 124 to a rocking plate 18, provided at the top thereof with a stop 18 and hinged to an angle-piece 19, secured to thc under face of the crossbar 14. A helical spring 2(), one end of which is secured to the rocking plate 18 and the other end to the depending leg of the angle-piece 19, has the tendency to force said rocking plat against said anglepiece, and consequently t c force the gripperbar 17 against the presser-plalc 16. Supported in brackets attached to the cross-bur 14 and extending parallel to the latter is a spindle 21, provided intcrmcdiatcly with a depending iinger 22, resting against the stop 16* of the rocking plate 18, and also with an arm 23, adapted tostrike astop 24 on the bed 13, as shown in Fig. 4, in order to rock said linger, and thereby said rocking plate.

The carriage a is provided with two longitudinally-extending bars 25, carrying a device c, intended to rcccivc the tablets or other articles to be wrapped. This device consists, essentially, of fixed vertical guides 26 and 27, between which the tablets are retained, and spring-actuated pawls 2!), provided with pro jections or teeth 28, the function of which will hereinafter appear.

Upon the bed 13 of the machine are arranged at what will be termed for purposes of description the front" of the latter two arms 30, extending outwardly-from said bed and carrying at their outer ends angular-lyadjustable cranks or levers, conncctci at their ends by a rod 252, on whiclgis suspended atone end by hook-shaped lugs 33* a Jlangcd plate Iii-intended to receive the wrappers. 'The opposite or front end of the plate 33 is supported above the bed-plate 13 are tlw'o disks 36, the

spindles or" which extend through said arms,

as shown in Fig 3. Bet can the disks 36 and connecting diainetrica ly opposite points of the same are arrangeiil relatively fixed feed-rods 37, covered with elastic material. The spindles of the disks 36 carry smaller disks 38 at their ends, and said smaller disks are provided upon their peripheries with ra dially-extending pins adapted laterally-disposed pins 39, carried by parallel arms 40 of the carriage a, said arms 40 ex tending longitudinally of the machine and be ing connected with the side members 100 of the carriage, as shown in Fig. 3. The pins 39 are pressed by helical springs against upright stop-pins 41 upon said arms 40, which prevent the pins 39 from turning in one direction, althongh they can turn in. the opposite direction against the tension of said springs.

Extending upwardly from the bed 13 IS a loaf-spring 42, the end of which rests on a flattened portion of the hub of one of the disks 35 in such a manner as to maintain said disks against movement and to insure their stopping in the same position after their actuation by tho pinsSl) on the carriage (1 Two cams 43 are arranged on the shaft 7, and on them rcst rollers 44 of a verticallyinovablc cross-bar 45, which extends transversely oi the machine. Said cross-bar 45 carries an upright 46,-npon the top of which is arranged a wrawpcr-plato 47, adaptcd to reciprocate vertically in an openin 90 of the bed 11%,ns best shown in Fig. 2. The plate l7 is hinged to the upright 45, so that it may he tiltcd to one side, although a spring 42s has tho tendency-to normally maintain it in horizontal position. Below the plate 47 and atlachod to the under part of the bed is a stop 45), against which said plate is adapted to abut at the end ol' its downward movon1cnt,so as to be tilted against the uppcr edge of an inclincd delivery-chutc 5(), arranged at the rcnr ol' the machine. The shaft 7 is further provided at ouch sidc of tho machine with iingcrs 51 52, which arc placed at dill'orcnt angular, distances l'rom each other. in the path ol' said lingers :n'c arranged rollers 53 54, carried at the lower cxl rcmitics ol' oppositely-inclined clbo\v-lcvors :35 56, pivoted to the sides ol' the frame. (lnc ol' the arms" ol' the lovcr 55 carrics a t'ootlnd segment 57, meshing with a wheel 5!), scoured to one end of a shaft 58, extending trnnsvcrscly ol' the niacblnc and journalcd in tho sides of the frame at at point approxinmtcly below tbc l'ccddisks 36. Sold shalt, which is controlled by to abut against carries a rocking arnri- 60, the rounded end of which passes through an opening in a slide-plate 61, guided longitudinally on the bed above an opening therein and to which is securedfby means of a s ring 63, a transverse folder-oar 62, mova le 1n the ,sarne plane .as said slide-plate. One of the arms of the lever segment 64, engaging with a gear-Wheel 66, carried by a shaft 65, similar to the shaft 58. The shaftfi, controlled by aspring 67 as shown in Fig! 1, is connected by a rocking arm to a second slidelate 68, similar to the slide-plate 61 and slide le in the same direction, the opening 90 and the late 47 being disposed between said slide-p ates. Theplate 68 carries, by means of a spring similar to the sprin 63, a folder-bar 69. Slidable through the datter is a rod 70*, attached at one end to a fold-retaining bar 7 0, exten' ing parallel to said folder-bar and adapted, to fit in a longitudinal recess or seat therein.

second bar 71 is arranged at the opposite end of the rod 7 0 and provided with u wardlyextending drivingpins 72, adapts to abut upon the reciprocation of the carriage toward the ri ht, as shown, against dependin lugs or hoo *s 72011 the pressersplate 16. n the path of the finger 51 is also arranged a roller 74, carried at one end of a bell crank lever 73,

i a spring 59,

crank lever 75 which is connected to a thimblc 77, carrying at. either and levers 78, said levers being normally retained in downwardlypointing position by springs 94. -The. ends of said levers 78 engage racks 79, uided vertically in the sides of the frame said racks in turn engaging with pinions 80, se-

otcd upon the bed at either end 0 the opening and adapted to fold inwardly.

'lhe Worm-wheel shaft 3 is connected to a spindle 35 by a-gearwzheel 5 and intermediate gear-wheels S2 83 and said spindle, which latter carries a cam 86, provided with two bosses or projcctions as. shown in Fig. 2. A vertically-guided crossbar 87 rests against the cam 86 by 'ineans'of a roller 38, and a plate 8%) is mounted on an upright support 87, carried bysaid crossbar 87.

The operation of the improved machine is as follows: The worm-wlnml shait 3 is driven by the wheels 1 2 4 and the main shaft 7 by the whcols 5 6 8. This results in the carriage o receiving. a laterally-rodprocating motion. When the lattcr moves toward the Wrappersnpporting plate 33), on which the sheets or" tin-toil or paper are held by means of the l clamps. 35, the pins 39 of l strike the pins of the plate 38 and being held I by the stop-pins 41 bring about the rotation l oithedisl is' 3d, the spring 42 being stretched i l and the Wrapper-'lecding rods 37 caiised tobe moved in n. circular path. One of the latter 56 also carries a toothed cured to the pivots of folding fla 81, pivthe suppdrts 40 which is in turn connected to a second -bell a gear-wheel 84 on 7 seizes hold of the upper sheet ol' tin-foil or other wrapper and causes it to move-lorwartl to a sullicient extent to bring its end to the grippers ol' the gripper device I). In the described movement of the carriage a the arm 23 strikes the stop 24, which causes the spindle 21 to turn, so that the linger 22 in rocking abuts against the lug 18* on the plate 18, and thus rocks the latter against the tension of the spring 20, the gripper-bar 17 thus being raised. The supply of tablets is arranged in the supporting device (1 ol' the warriagc above the plate 89, and when the carriage arrives at the end ofits movement toward the wrappersupporting plate 33 said plate 8!) is maintained in raised position by one of the bosses or projections of the cam S6. The ends ol the tablet-retaining pawls 2!) rest then against the plate 89 and release the pile of tablets, so that the bottom tablet can fall on the plate 89. \Vhen the carriage moves then in the direction of the arrow, Fig. l, the projections 28 on the pawls 29 press under the action of their springs 91 against the. last but one tablet, and thus retain the upper tablets in position while the plate 89 elescends with the lowermost chocolate tablet released and carried by it, owing to the movement of the cam 86, which allows the roller 88 to descend. At the same time the arm 23 releases the stop 24 and the linger 2 releases the rocking plate 18, which is then moved by the spring 20 in such manner that the gripper-bar 17 is lowered and presses the wrappersheet against the plate 16. This sheet is then carried until the carriage arrives at the end of its movement in the opposite direction, in which the plate 18 strikes a partition or stop plate 92 adjacent the plate 89 and moved in such manner as to raise the gripper-bar 17 in order to permit the wrappersheet to fall over the opening 9()that is to say, on the hinged folding-plate 47. At this moment the second projection of the cam 86 raises the roller 88 and the. plate St) until the tablet carried by the latter is pushed by the same between the engle-piece it) and the plate 18, which constitute a carrier having an open bottom and a movable side member. \Vhen the earriage u. returns to its position shown in Fig. I, the tablet taken from the support. SS) is held, by the spring 20 between the plate 18 and the angle-piece it), which together form the carrier or transporting device and which carry it until the arm 23 strikes the stop 24 and rocksthe tablet-clamping side memberor plate 18 by means ol the spindle 2t and o'l'the linger 22, the result being that the tablet is released aml hills on the wrapper covering the l'olding-plate -17, Fig. 2. Ateach |nove- 'menl ol the carriage u in the direction ol the arrow in Fig. l aml al'ter each wrapper has been seized the lingers 5t 52 meet the rollers oil .';--iol' the levers 55 5t) am! by means ol' l he toothedscgmentsSTti l andol'thecoiiperating l l l l wheels 5!) titi bring about the rotation ol' the spi'ndlcs 5H and (35, whereby the folder-bars ($2 and (it) (the ends ol' which are beveled) are moved by the levers tit) and the slide-plates ti] and (S8. The linger 52 is ol' such shape and arrangement relatively to the linger 51 that it only 'ausesa small movement of the folder-bar (it) against the plate 47 until the latter linger leaves the roller 53 for the purpose ol' pushing the tablet, which otherwise would not fall at once, owingtothe resistance ol' the wrappersheet. The l'olderbar 62 l'alls then under the action of the finger 51 on the tablet and folds in the manner indi 'atetl in Fig. 5 one of the edges ol' the wrapper, which, after the tall ol' a tablet, assumes the shape shown in Fig. 2. When the linger 51 releases the roller 5.3, the bar 62 is withdrawn. into its original position by the action of the spring 5!). At the same time the tinger 52 brings about the continuation of the movement of the bar (it), so that the edge ol the wrapper-sheet which is above is also l'oldcd. \Vhen the linger 52 is free ol' the roller 54-, the bar (it) is returned to its original position by the spring ($7. The bar 71, connected to the bar 70, then strikes the stops 93, secured to the table top or bed 13, and thus prevents the retreat ol' the bar 70, which rests then against the last-folded edge of the wrapper-sheet, Fig. 6. During this movement the cams 43 on the spindle 7 have turned to a sullicient extent to enable the rollers ot' the cross-bar 45 to arrive at the projection 43, which brings about the descent ol the crossbar with the plate 47. At this moment the linger 51 strikes the roller 74 ol" the bell-crank lever 73 and through the intermediary ot the b ll-crank lever 75 causes the spindle 77 to turn. The levers 78, secured to the spindle 77, move the racks 7t), wbichcause the pinions St) to turn and lower the flaps 8 arranged at the ends ol the opening 90, b which the wrapper, not yet l'olde d at the said ends, is l'olded in its turn on the tablet, as shown in Fig. 7. The l'old-retaining bar prevents the portion ol" the wrapper already l'ohied on said tablet l'rom rising again. in being ac.- tuatcd the llaps Si abut against and slightly raise the l'older-bar tit), which resumes subsequently its position under the action of its spring 67, this being for the purpose ol' avoiding lriction ol" the bar 69 on the wrapper, which would spoil the. latter. l'Vhen the linger 51 has released the roller 74-, thc springs 94 operate thelevers 7S and bring the llaps 81 back to their original position. When the spindle 7 continues its rotation, projections 43" on the cams arrive under the rollers 44, so that he. cross-bar can descend l'arther still with the plate 47. The latter is tilted by the stop ll), whereupon the wrapped-u) tablet escapes l'rom it aml slides down the chute 50. The carriage (1 has in the meantime advanced sulliciently toward the plate 85) to enable the books or lo s 2' to come in contact with the pins '72 of toe bar 71 and cause the latter to participate in. the movement when the car-- l'iage it continues its movement above the steps 93 until the rod 79 is retracted into its seat in the folder-bar 69, whereupon the'carriage again reac ,es the end of its travel'in which the rri'apper-sheet carried by the cripper device 72 falls on the opening 30 an the plate 47. The same operations then begin again, a tablet being seized. by the carrier (plate 18 and angle-piece l9) and brought onto the plate 47, while at the same time a tablet is deposited by the device 6 on the plate 87. Then a new Wrapper-sheet is seized and carried by the gripper device s while the tablet placed on the plate 47 is manned u by the Wrapping devices.
