WRAPPING-MACHINE.

SPECIFICATIOH forming part of Letters Patent No. 478,396, dated July 5, 1892.

' Application filed June 3.1890. seen N0. 354,114. on model.)

To all whom it may concern:

Be it known: that I, MARTIN EUGENE Bruce HAM, of the city and county of l hila'delphia, and State of-Pennsylvania, have invented an- Improvement" in Wrapping Machines, of which the following is a specification.

My invention relates to wrapping-machin es, and it consists of certain-improvements,which vidual packages or articles by'means of mechanism operating with the requisite rapidity, precision, and neatness.

The feeding, pasting, and folding operations are all carried on successively and are so timed with reference one to another that the operation of the machine is continuous and rapid.

In carrying out my invention I employ suitable feeding devices forfeeding the wrapping material or paper to the folding devices, and as the paper is being fed it is cut into appropriate lengths and provided with paste. The articles to be wrapped are fed one at a time into position upon the wrapper, and the sides and ends of the wrapper are then successively folded over,the paste upon the ends or edges causing them to adhere.

My invention includes certain improvements in the feeding and pasting devices and the means of operating them, whereby the paper or wrapper is fed positively to the folding devices and the pasted portions are prevented from coming in contact with any of the parts of the machine, so as to be liable to adhere to them or communicate any of the paste to the mechanism.

My invention also includes improvements in the feeding devices for feeding the articles into position to be enveloped in the Wrapper and in the manner in which the articles are held in position while that operation is being performed, as well as in the folding devices themselves and the mechanisms for operating and timing the various. parts, and in certain new constructions and combinations thereof, which are hereinafter more fully described jand'claimed. i

'-In the drawings, Figure 1 is a front elevation of my improved wrapping-machine. Fig. 2 is a vertical-sectional view of the same on i the line a; x of Fig. 1, looking toward the left. Fig. 3 is a front'elevation of the upper por tion of the machine with some of the parts removed. Fig. 4 is a side elevation of the ma chine, illustratingthe power-transmitting connections. Fig. 5- is a sectional elevation of the paper feeding and paste supplying devices on the line 'yyof Fig.2. Fig. 6 is a perspective View, on an enlarged scale, of a portion of the folding devices removed from the other parts of the machine; and Figs. 7, 8, 9, 10', and 11 are perspective views of a cake of material and wrapper, illustrating the successive steps of the wrapping operation.

A is the main frame of the machine.

B is a table to support the articles to be wrapped.

0 is a vertical plate carried by the frameA, provided with vertical guiding-wing c, and arranged a distance from the end of the table B and extending down so as to form a feeding-chute G. The plate 0 and the wings c 0 form, respectively, end and side guides for guiding the article to the chute C. I prefer to form the upper surface of the table B of a smooth piece of metal b,extendinga distance between the guiding-wings c and having its inner end extending downwardly'to form with the plate 0 the chute C. v

D is a support under the end of the chute O to receive the-articles as they arefed down it. D is a sliding block or pusher guided ,in

slots d in the frame above the support D,

whereby the articles are pushed from the support to the jaws of the feeding-plunger E. This sliding block is provided with an arm or extension D which is pivoted to a lever D This lever D is pivoted to the main frame at d and carries a roller (1 It is actuated bya cam 2, carried by the shaft 1, which strikes the roller (1 as it rotates, and thereby rocks the lever D and imparts a reciprocation to the sliding block 1).

D is a spring to draw back the lever D and block D after they have been actuated by the cam 2. I

E is a plunger guided in the main frame A and carrying upon its end a block H, which supports two nipping-jaws H H. These nipping-jaws H H project below the face of the block H and are drawn toward each other by means of springs h h. These jaws H H are preferably constructed in the manner shown in Fig 6, consisting of angle-plates supported by the block H, provided with slots 7L2, through which extend guiding-plates H projecting from the ends of the block so as to guide the jaws in their movements, and having the springs h h, connecting them upon the top of the block 11. The lower portions of the jaws upon the side-adjacent to the sliding block D are providedwith small guiding projections 72. curved or inclining outwardly to guide the article fed by the sliding block D- between the nipping-jaws H H. The plunger E carries upon its upper end a roller 6, which is operated upon by. a cam 3, carried upon the main power-shaft G to depress the plungerE for the purpose of feeding the article carriedby the nippingjaws H H to the folding devices. The plunger is, raised again after the operation of the cam 3 by meansof a spring a connecting an extension E of the plungerE with the main frame A.

J is a chute under the plunger E, provided atits upper open end with jaws J J to receive and support the article during the wrapping operation. These jaws are preferably constructed in the manner shown in Fig. 2, consisting of two angle-pieces bolted upon the outside of the chute J andfprovided with lips jj, projecting over the top ofit. The bolt securing one of these jaws J is provided with an elastic packingj' to permit a slight yielding of the jaw, the upper part of the chute J being formed to permit the resulting movementof the lip j.

K K are sliding folders arranged over the jaws J J and guided by them, the upper edge of the jaws being recessed or cut away, as shown in Fig. 2, to receive the folding edges k of the folders K. folders are shown in Fig. 6. In addition to the fiat surfaces K and the folding edges 70 they areprovided with projecting foldingblocks K on their sides forfolding in the sides of the projecting ends of the wrapper in the manner hereinafter more fully disclosed in the-description of the operation of the machine. Between these folding-blocks K and the upper portion of the folderK are recesses or slots 70 One of the sliding folders K is operated by two levers L L, connected to it by links 1 Z and pivoted to the main frame at Z, and the other is operated by corresponding levers M M, connected to the folder by links m m and pivoted to the main frame at m. (See Figs. 1 and 2.) The levers L L and M M are provided upon their free ends-with rollers L and M respectively, and are operated by sets of cams 4 and 5, respectively. These cams are carried by the shaft G. Thecams 4t, operating the levers L L, are arranged oppo- The details of these a sitely to the cams 5, which operate the levers MM,so that the levers L L andM M will be rocked alternately, first operating one sliding folder K and then the other, as is hereinafter i supporting the wrapper above the chute J,

carried by arms N N, pivoted at n to brackets A A of the main frame A. These arms 'N N are provided with extensions N N which fit into cam-grooves 0 upon wheels 0, carried by the shaft I. By these cams o the wings N N are moved from under the paper or wrapper to release it when itreceives the article to bewrapped: frointhe plungeriE and to permit the folding devices to operate.

The levers L L and M M P P are reciprocating folders for foldingthe upper projecting ends of thewrapper, carried 'by rods P P, guided in the main frame A, and operated by cams 6 6, carried by the shaft:

G. The rods P P are raised to their normal positions after they-have been operated: by. the cams 6 6 by means of springs 19, connecting extensions P P ofthe rods P P with-the main frame A.

(See Fig. 1.) The reciprocating folders P P are preferablyarranged adjacent to-the nippers H H and provided with slots 10 to admit the projecting guidingplate H of the block'I-I (see Fig. 3) and" are pivoted to the rods P P, as at 19 and springpressed-againstthe facesof the nippersH H by the springs 12 Q Q are two reciprocating'folders forfolding the lower projecting ends of thewvrapper after the upper projecting ends have been folded by the folders P P. These reciprocating folders QQare preferably arranged on the inside of the chute-land are connected with links Q Q, upon the outside of the chute, by means of bolts passing: through guiding-slots 7' as shown inFig. 3.

Q Q are arms pivoted to the links Q! Q.

t q q; and pivoted to a bracket or support v The end of each arm Q rests upon a supporting-lever G, journaled on the shaft F.

R Rare disks carried bythe shaft I, provided each with a pin or projection '1', adapted to strike the free endG of the lever G when itis moved toward it. The disks RR are also provided with cam projections R, which.

as the disk R rotates strike the endsof the levers Q depressing them and operating the.

IIO

folders Q Q. This action also operates the levers G G so as to throw the ends G G 'in the path of the pins or rollers 7 by WhiOllihB levers are moved back again intotheir normal positions, operating the levers Q Q and lowering the folders Q Q. The friction between t-he folders Q Q and the wrappers will until they are lowered again in the manner maintain the folders in their raised position just described.

S is asupply or rolloft the wrappingmaterial, from whichit may befed ina continuous web over. a guiding-roller 8? between the guides S S te the feeding-rollers T T. p

S is an idler-roller, preferably coated with rubber or other similar material-to insure a true feeding of the material to the guides and feeding-rollersf The feeding-rollers T and T are carried upon shafts T sta T respectively. These shafts T and T 'are journaled .in the main frame A and are geared. together by means. of gears 1'1 "The journals of the shaft T are preferably made adjustable in the frame the roller T may be adjusted to orfrorn the,- roller T. Of these rollers T and T, I prefer to construct one T. of metal and the other T Q of rubber and of smaller diameter, as by this means I obtain a better feeding action. The roller T is provided with annular grooves or recesses t, into which project strippers or fingers U between the surfaces of the two rollers T and T. By this means the wrap-' ping material or paper is prevented from adhering to the rollerT. These fingers are carried by a cross-piece A of the main frame A.

A is a roller for the guide it to the cutters.

T is a cleaning-bar arranged in contact with the surface of the feeding-roller Tto remove,

from it' any paste that may collect thereon from the roller T.

U U are paste-receptacles supportedby brackets of the mainframe above. the ends of the rollers T.

U U are paste-distributin g rollers by which the paste from the receptacles U U is fed upon the ends of the roller T and thence V distributed upon the. edges of the wrapping material. These paste-distributing rollers U U are carried upon shafts u M, which are op:

erated by gearing U? U between them and theshaft T of the roller T.

V is a shearing-cutter pivoted at 'v to the stationary cutter V.;-. These cutters are arranged between the rollers T T and the folding devices, so that the wrapping material is cut into appropriate lengths in passing from one to the other. The-pivoted cutterV is connected by a link V toa reciprocating rod V guided in a cross-ba r .:of the main frame A.

The upper end of this rod V is arranged in the path of the plunger-actuating cam 3, so that the cutter is operated immediately before the operation off-the plunger E. A spring V between the rod and a portion of the frame A normally raises the rod V and the. cutter V after they have been operated by i the cam 3.

V are feeding strippingrollers for the cutters V V to guide the paper or wrapper to the folding devices.

. W W are vertical guides below the chute J, forming a continuation ofthe chute down which the wrapped packages descend. (See Figs. 1 and 2.)

slight pressure upon the folded ends of the packages as they descend, being connected paper or wrapper to T upon the shaft T These vertical guides exert a;

,to the bottom of the chute J by. bolts to with sufficient looseness topermit slight play.

W W are pressure-blocks guided upon a rod W and drawn toward each other by means ,of springs W so as to exert a pressureupon the guides W W. and press them, against the articles descending between them. This.

I pressure maybe regulated by means of a link W connecting one of the pressure-blocks W with an adj listing-screw W.

G isthe main driving-shaft, and F the driv-. inIg-wheel, which may be connected or disconnected with the shaft Gbymeans of a clutch F.

The power transmitting connections are shown moreclearly in Fig.4..

The shaft G is provided on its end with a bevel-gear F and the shaft I is similarly pro vided with a bevel-gear 1 Power is trans,

mitted from the shaft G to the shaft Iby means of a shaft Y, journaled in bearings j upon the main frame A, and provided on its ends with bevel-gears Y and Y gearing, re-. spectively,with the bevel-gears F and I of the shafts G and I. The shaft I is provided upon its opposite end with a crank-arm I I is a connecting-rod connecting the crankarm I with a link T loosely journaled on the shaft T. This link carries a spring-pressed pawl I, which engages the teeth of a ratchet I By this means an intermittent rotation is imparted to the shaft T and to the feeding devices operated by it.

'The shaft T and the shaft S of the. supplyfroller S are provided, respectively, with "sprocket-wheels X and X, which are connected together by means of a chain Z;

The operation of my apparatus is as follows: The articles to be wrapped are fed from the table 13 and are arranged oneupon the.

other in the guide 0 and descend one at a.

time down the chute O to the support D.

:The pusher D is then projected by the action of the cam 2, pushing'the article between the nippers H H of the. plunger E. Simultaneously with this operation the paper or wrap-v ping material has been fed from theroll S through the guides S S between the rollers TT and is supplied upon its edges with paste from the paste receptacles U U. The paper.

thus pasted is guided by the stripping-wires U U'U and the roller A between the cutters which are operated by the earn 3 and cut the paper into the appropriate lengths. The cut paper or wrapper is fed in. position over the folding devices K before it is cut by the cutters V V, and is supported above'the folders bythe wings or supports N N. The cam 3 now depresses the plungerE and lowers the article to.

be wrapped upon the wrapper and forces it down into the opening of the chute J, where it is supported between the lipsjj of the jaws J J.

Simultaneously with .this operation of the plunger the wingsN N.have been operatedby the cam-grooves 0, moving them out of the. way, so as to release. the which is now held between ,thejaws J J with.

,paper. or wrapper its sides extending upwardly in the manner shown inFig. '7. The levers M are thenoperated bythe-cams- 5 5, projecting forward" oneof the folders K and folding down one of theprojecting sides on the top and also fold ingin the corresponding sides of the ends, as illustrated'in Fig. 8; Immediately after" this operation the levers L are operated by'the cams-4 4, folding downthe other projecting wrapper causes them to adhere when foldedtothezarticle itself and to the wrapper, as in dicated Meanwhile the machine has been operatingto bring another wrapper into positionnnd to deposit a'se'cond article uponit' in the manner heretofore described. As this nextrarticle is-pushediinto position between thesjaws J Y 'J t the article already wrapped. is

pushedidownthe chute J 2 The folders Q Q arecaused' to return to theirformer positions by means of thelever G and the pin r in the manner-heretofore described. The tension of the guides W upon the pasted ends of the wrapped article causes those ends to adhere and prevents-them springing loose before the paste has sufficiently dried.

'Dhevariousoperative cams are so arranged with reference to eachother and are so timed in their action that thesteps are performed successively and the machineoperates continuously, going from one step to the next, and while one article is being wrapped another isbeingbrought into position and anew wrapper is being'prepared, so that the machineoperates with greatrapidity and the jof supporting-jaws to supper-t the artieleand wrapping is performed with perfect precision.

While Iprefer the details of construction which are hereshown, I do not limitmy invention to them, as it isapparent that they maybe modifiediwithout departing from-the spirit of my invention.
