To all whom it may concern:

Be it known that We, O'rro Ricerca and LOUIS FREDERICK, citizens of the United. States, residing at,Sa-lem, in the county of Columbiana and State of Ohio, have invented' new and useful Improvements in Trapping-.Machines offwhichthe following is a specification.

This invention relates to wrapping maarticular reference to a machine for Wrapping loaves of bread.

The invention has for its object to produce an organized machine including means for feeding paper from a roll to a loaf-receiving position, means for cutting the paper, means for supplying or depositing a loaf upon the paper, means for folding or wrapping the paper about the loaf, means 'for sealing or pasting the Wrapper and means for ejecting the wrapped loaf, the several operations being performed in proper succession.

A'further object of the invention is to simplify and improve the construction and operation of a machine of the character described.

With these and other ends in view which Will readily appear as the nature of the inbvention is better understood, the same consists in the lmproved construction and novel l arrangement and combination of parts which Will be hereinafter fully described and particularly pointed out in the claims.

In' the accompanying drawings has been illustrated a simple and preferred form of .the invention, it'being, however, understood that no limitation 1s necessarily made to the precise structural details therein exhibited,

but that changes, alterations and modifican tions within the scope of the claims may be resorted to when deslred.

The .springsl T23 serve to keep the flaps (3l) normally extended in aliiieinent with the plates t'itl. the stop meinbers 75 being arranged in the path of said tiaps toliinit their movement in an outward direction; but said flaps may be tolded or bent from the plates (Sti in an inward direction toward each other, against the tension 'ot' the springs T4 by the nieaiis provided `lor the purpose. Yb'hen the slides 55) are moved upward from the initial position shown in Fig. 3 by the action ot the leversl (32 engag- 'ing the pins (31, the plates (lo farryiug the flaps (if), which are extended in alim-nient therewith, will be moved upwardly adjarent to the sides of the bread supporting table. Assuming the wrapping material and the loaf to have been previously deposited upon said table. the side portions ot the wrapping sheet will be. carried upward adjacent to the sides of the loaf until the slides approach the upper limit. ot' their increment. The inner ends et the links or levers (3l will now engage the st( p members (l5, thereby tilting the outer ends ot said links upward as the upward movement ofthe slides 59 recedes. This upward movement et the slidesvwill, however, be checked by the tlanges (SS-of the platestt engaging the underside of the the tension of the spriiigsi, thereby tolding the edges of the wrapping sheet over the top of the loaf. The operation inav be readily so timed that the movementot' one of the flaps will slightly pi'eeed. that ot the fotiie' flap, so that one edge ofthe' wrapping 'sheet will Vbe placed above and. upon the opposite edge to presentthe iippere'anec in-l .iiicated in Fig. 9.

Slidably Supported between the end walls of the casing 43 ot the bread chuteand the interior jaWKmembers Ll ot said chute are slides Z5, each provided with-guide pins 76 extending through a slot 77, said guide pinspbeiag connected together by a keeper TS which likewise projects through .said slot. .-i ifetracting spring Tt) is suitably connected with one ot the pins T6. Each keeper TH is engaged by one end oi' arin of a lever St) iuleiuined at Si, and the other arm ot' which lies in the path o'l cani members Si., Si); upon the disks .3() which are mounted upon the shat't 5l liereinliel'ore described. it being understood that each disk carries two suitably v i disposed cam members Sil, Si), which will sureessively engage one ot the levers Htl. so that' the .slide :i-ssoeiated wai-tti such lever will be actuated twice to each rotation ot the disk 5t). lt is also, ot course. tobe understood that the cani members S2, .s2-l are to be so dis posed that the operation otl the slides T5 will be properly timed. l`he slides T5 are equipped at their lower ends with turliing nien'ibers or blades Hl, as best seen in Fig. vl. l The plate 5t) which inten-:eels the plate 55 at right angles is -provided adjacent to its edges and at, opposite sides ot the plate 55 willi guide slots Si'rthe upper ends of which are curved inward in the direction ot each other, as shown at 8G.

lQupported adjacent' to lach slot 85 is a slide S7 having pins or guide members SS' that extend into or through the slot, one of said guide nie'iiibers being connected with one end ot a retract-ing spring 8S), .the opposite end oi which is suitably connected with the framework of the machine to torce the slide in a downwardV direction. Associated with each sli-de 8T and movable therewith is a triangular cani ineniber tltlwhieh projects at opposite sides ot the plate 5G, being provided with beveled faces 91 adapted to en -v gage the beveled vlower ends of levers 92 which are fulcrurn'ed at 93 upon brackets 9i that project upon opposite sides of the plato 5G. Each slide 87 is provided with a tappet stud 95 lying in the path of one arin ot` a lever Sltj lulcrunied upon an upright'll?. The upper ends of the levers 92 are equipped willi 'tueking blades 0S, and said 'upper ends 'are normally thi-'own outward troni each otherbyl the action o'l" suitably arranged Springs'tlt). The slides S7 are also equipped at their upper ends willi folding blades 100,. the operation of which will be presently described. l

The .levers 06, see Fig. 3, are extended in the path of levers 101 which are iiilcrumed upon-suitable supporting members, as indicated at 102, said levers being extended in the path ofpam members 103 associated with disks 104, 105 which are mounted upon the shafts l and 2, respectively. It will be seen that whenthe levers 101 are actuated by the cams 103, the engaged ends of thelevers 9G Will be depressed, thus lifting the slides 87 against the tension oi the springs 8S) and :aiising'the folding blades'lOO to be moved upward past the ends of the loaf support;- ving table. At the same time, the lower ends ios Q1. rupon suitable uprights 11,0, 111, are

Locale? of the levers 02 will be forced apart by the l upon the loaf supporting table, how the action ot the cams 01 against said levers i loaf is deposited upon the wrapping mate and against the tension ot the springs nl), thus forcing the opposed tuckiiig blades 05 -at each end of the loaf supporting table in the direction of each other. Then the iipper guide member S8 engages the curved upper end of the slot 85, the upper end ol the slide 87 will be slightly tilted in the direction otl the loaf supporting table, thus causing the vfolding blade 10() to be pressed in the` direction ofthe end ot the leal". ldlien the levers 101 are disengaged 'lroni the cam members 103, the parts will be retracted by the action ot' the spriinqsy Sl).

The disk 101, in addition to the cam meniber 103, is provided with a cam projection 106 making a similar cam projection 10i' upon the disk Ll() which, as previously described, is mounted upon the driving slialt Levers 108, 100, which are ifiilcriiiiied tended in the path oi the cani members 1013, 107, and said levers are connected by linksl 112, 113 with, the levers G2 which are thereby actuated to operate the sheet folding devices, as previously described.

An ejecting device is provided which consists oit an arin 11e which is liingedly connected at 115 with the traine et the machine, and it is engaged by a suitably constructed cam Wheel 116 upon the driving/shaft a spring 117 being provided to4 force the arm 114 in the direction of the cani wheel to. hold it in engagement therewith. Hingedly connected with the arm ll-l adjacent to the upper' end of the latter is a suii'.- ably guided plunger 118 which is adapted io be projected by the action of the spring 1liover the loaf supporting table in the direction of a discharge chiite 11S). During the greater portion of the rotation of the cani Wheel 11G, the ejecting device is held in retracted position against the tension of the spring 117, but the cani wheel has a llaltened tace 120 which permits the ejector arm 114: at one time 'during the rotation oi the cam wheel to be quickly moved by the Aaction of the spring 117 across the loa't' sup porting table for the purpose of projectingthe wrapped loaf on to the chute lli), the ejector being quickly retracted against the tension of the spring 117 to a non-obstructing position witirreferenee to the loa'l supporting table and the feed chute. lffiluitably supported upon the slides i7 carrying the tiiekingniembers 84,' and suitably connected with and spaced Yfrom said tiicking blades are brush members 121 which are. coiineclcd by flexible ducts 122 with suitably arranged reservoirs 123 containing' liquid glue or ienient of any descriptionwhich may thus be applied to the wrappers.

. 5 movable means slidably connected i\ lt has in the lfoi'egoing been described hnwH leed chute t'or Yfolding the wrapp l5 the wraixiping paper is supplied and placed l rial downward rial and how the folding devices are actuated to fold the two sides of the sheet over the top of the loaf. This operation is fol-- lowed by the rapid descent of the tucking members Sft, whereby the ends of the wrapping iiiatciial are folded downward upon the ends olI the loaf, as indicated in Fig. 10. During this iirst operati-on ot the blades or tiicking members S-l the brush members 121 will not contact with any portion oftlie wrapping material. During, or immediately succeeding the first retracting inove ment of the blades S1, the slides 8'? are moved upward, engaging and actuating the `levers 92, whereby the tii'cking members 08 will fold the wrapping material from opposite sides of the loaf upon the ends of the latter, producing folds which are indicated at 19t in Figs. .l1 and l2. While the tuckingI nreii'ibez's 98 are thus engaged, the blades S1 descend a second time and yare immediately -ollowed bythe upwardly movingn blades 100 carried by the slides 87, and

whereby the tongue 125 of the wrapping material at each end of the loaf is folded iipward and inal'ie direction oit the end of the loaf, being at the saine time wiped over the brushes which aie inoislened with adhesive material. The blades carrying the brushes are retracted before the blades 100 oomplete their upward and final ytilting Inoveiuent in the direction of the ends oit the loaf, which results in the flaps or tongues 125 which are inoistened with adhesive mat/:rial being pressed firmly against the tiaps 1% and the previously dowiiturned ends ot the wrapping material, as clearly indicated in Fig. 12, thus completing the wrapping of the loaf. which latter is now discharged` t'roiii the supporting table -11 on to the chiite It is obvious that the various operating parts ol` the machine. including the cams, are to be so proportioned and arranged that the several operations will be performed. in

proper sequence and :it the proper times. Ii is l'uillier evident that by each complete revolution oit llic driving. shafts 1 and 2 a coliiplete cycle ot operations will be perlorined to produce llic desired result. l
