SPECIFICATION forming part of Letters Patent No.394,772, dated December 18, 1888.

Application iiled March 26, 1887. Serial No. 232,577. (No model.) i

To all whom it may concern:

Be it known that I, XVALTER S. JARBOE, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State 5 of Pennsylvania, have invented certain new and useful Improvements in Package-Irapping Machines; and I do hereby declare the following' to be a full, clear, and exact description of the invention, reference being' Io had to the accompanying drawings, which form partof this speciiication.

In Letters Patent No. 367,637, gral'ited August 2, 1887, I have described a packagewrapping machine wherein the paper which I5 is to form the wrapper is intermittently fed to a pair of shears, which cut off a sheet of a size adapted to enfold .the article to be wrapped, the sheet so cut off being' then manipulated and automatically folded over and 2o around and in at the ends of the article being wrapped by means of certain peculiar mechanism and moving parts operated from a common shaft.

My present invention has relation to pack- 2 5 age-wrappin g machines, and is designed as an. improvement on the machine described and shown in my aforesaid application for Letters Patent, and embraces many of the essential features of that application, as well as cer- 3o tain new and novel features which will be hereinafter fully described and claimed.

In the following description I will refer as briefly as is consistent with a full and clear understanding of my present invention to the v3 5 portion of the apparatus already described and shown in my before-mentioned pending application, and will more specifically describe those parts which I believe to be new. My present invention has for its obj ect the 4o provision of novel means1 for automatically wrapping packages 0r blocks of solid material in paper or other flexible material.

My invention has for its further object the provision of means for automatically wrap- 45 ping' articles, packages, or blocks of solid material in a double wrapping of paper or other flexible substance-that is, two separate sheets or sections of paper or other suitable material one over the other ata single opera- 5o tion.

My invention has for its still further object the provisions of means in a package-wrapping machine for readily adjusting the machine to wrap packages, blocks, or articles of different sizes.

My invention has for its still further obj ect the provision of novel means comprising the peculiar construction, combination, and arrangement of parts hereinafter described for more rapidly, accurately, and neatly enfold- 6o ing and wrapping packages than has heretofore been possible.

My invention therefore consists in the construction, combination, and arrangement of parts more fully described hereinafter, and 65 specifically pointed out in the claims.

Referring to the accompanying drawings, Figure l is a perspective View of my improved wrapping-machine; Fig. 2, a side elevation of the same; Fig. 3, a plan view of the same; 7o Fig. 4, a plan view on a larger scale of the framing of the folding devices; Fig. 5, a detail view showing one of the movable plates which support the article previously to its being wrapped; Figs. 6 and '7, sectional views 75 of the supporting-plates and their appurtenant parts; Fig. 8, a plan view of the sidewing folders; Fig. 9, a plan view of the papersupporting' forks and the device for operating the same; Fig. 10, a side elevation of the 8o same; and Fig. Il, a plan view of a portion of the bottom of the table of the machine, showing the devices for adjusting the sideangle folders. Fig. 12 is a vertical transverse sectional view on line of Fig. 2. Fig. 13 85 is a perspective view of the side-folders and operating mechanism. Fig. 14 is a vertical longitudinal section, on enlarged scale, of that portion of the machine which embraces the folding appliances. sectional view, on enlarged scale, of the upper part of the machine on the line z .e of Fig. le. Fig. 16 is a series of views representing a package in different stages while being enfolded. 95

A designates the table upon which the working parts of the machine are mounted, and a a a the legs supporting the same.

B designates the main or driving shaft of the machine, suitably journaled in bearings roo Fig. l5 is a transverse 9o 71 l), sustained by the legs a a, and carrying the cam-wheels E Bi, the mutilated gearwheel B2, and the band-wheel B", through which and a crank, Bi", on the end of the shaft motion is communicated to the working parts of the machine.

Upon vertical arms c c and horizontal arms c c at one end of the table A are respectively journaled two rolls or reels of paper or other material suitable for enfolding the article to be wrapped, said rolls or reels being lettered C C and sustained on shafts c2 The strips ot' paper or other wrapping material from the rolls C C are designated (7 e, and each strip passes through a pair of feedrolls constructed and operating in the manner ol' the feed-rolls employed for a like purpose in my before-mentioned Letters Patentthat is, each pair ot feed-rolls consists of a large roll intermittently operated by means ol' a dog upon a reciprocating` arm taking into teeth upon a wheel Iixed on the shat't of the roll, and a spring-stop, el, and a smaller roll mounted in an elastic bearing, thepaper passing between the rolls and being fed positively but internlittently forward by their motion.

D designates the upper and smaller feeding-roll for the strip (7, journaled in bearings D D', risingl from the table A, the journals oi' said roll being` pressed upon by springs iitted in sockets 7 (7', and Dl designates the lower feed-roll mounted on a shaft, d2, that is journaled in hangers 73 (7ii on the bottom oi' the table A. The shat't d2 projects beyond the hanger on one side, and to the projecting end of the shaft is secured a wheel, D, having teeth t7 d" d" t7", with which engages aspringdog, (75, on an arm, (7, loosely mounted on the shaft. The end ol the arm 7 is pivotall y attached to the lower end of a vertical rod, (7T, which is pivotally attached at or about its middle to a curved pitman-rod, 17S, connected at its other end to the crank B on the end ot' the main driving-shaft B.

B designates the larger feeding-roll for the strip e, mounted on a shalft, e2, journaled in standards E E', and having a wheel, Ewith teeth el er1 e c", a pivoted arm, e", carrying a dog, c, and pivotally secured to the end of the vertical rod (77.

E2 designates the smaller [feed-roll ol' strip e, journaled in the standards E E and sustained on springs in sockets e e. The l'ecdroll l)2 of the strip (7 is, it will be observed, somewhat larger than the feed-roll E of strip e, and by reason of this dillerenee in the size ot' these rolls the strip t7 will be li'ed :forward a somewhat greater' distance than the strip c at each downward movement ol' the vertical rod (77.

The several rolls I) E D2 E2 are grooved, and guiding-wires f f f f on frames F and l1v project through the grooves and serve to guide the strips (7 and c to the cutting-shears.

G designates the stationary blade ot' the shears, tixed on a standard, G', and G2 designates thel movable blade of the same, which is fixed on a rock-shaft, G3, that is journaled. in the standard G and in a standard, Gl. A ever, G5, is secured to the rock-shaft G near the standard Gl, and through said lever the rock-shaft receives motion from a verticallymoving' portion oli' the folding devices.

llaving thus briefly described the device for feeding the wrapping material, I will now describe thc frat 11e-work of the wrappin devices and the manner in which the same may he adjusted to accommodate articles or packages of different size, and will then describe the moving parts of the wrapping devices.

ll ll ll lll ll2 ll2 designate six posts or pillars rising from the table A and joined together by cross-pieces 7ly 7i 712. Upon top oi' the cross-pieces 7e 7L 7l2 are laid two T-irons, l I, which extend from the shears to near the end otl the table A. These two irons are secured upon top of the cross-pieces by means ot' laterally-projecting tlat strips fi '11, having slots 'i' t near their ends, through which pass screws 172 i2, that rise from the standards l-I H and lil H, fitted with thumb-nuts "3 fi, By means otl the slotted strips 'l'. 'i and the thumbnuts 'iii l the distance apart of the irons I l may be readily adjusted and fixed, and, as these irons support and carry the adjustable portions ot' the frame-work of the wrapping devices, the whole adjustment of the trame is accomplished by loosening the thumb-nuts alulmoving the irons I l together or apart. From each of the irons I l', near the rear end ot' the same, depend two vertical posts, K K K K, and to the insides ot these posts are secured two metallic plates, K K whose forward ends are spirally curved, the (mrvature ot' the ends serving, as will presently appear, to lorm the last Iold ot the wrzLpping material upon the article orpackage, and the straight portions ot' these plates Yform the sides ol the chute or passage through which the wrapped articles are delivered from the machine.

K2 (lesignates a wide Ilat plate fixed horizontally between the vertical plates K K and forming a part of the top ol' d elivery-cluite above re'lerred to. The plate K2 has a wide upturned end, K3, the lower edge ot' said plate being roumled oil, as shown, and this upturned end serves as a shield and stationary folder, aetil'lg to li'old down the horizontal flap oi' the wrapper as the article is pushed under said plate. To the plate K2 are secured two cross-hars, 7x5" 7.9i, slotted near their ends and having uprights Kl K", which V(it into tubular sockets 7s." 7.1i on the under side ot the crosspieces 7L 71.. Spiral springs may be arranged within the tubular sockets 71'." 71:", and the said sockets and spiral springs serve to guide and sustain the top oi' the delivery-chute and permit the same to give il' any ot' the articles passing theretllrough should be thicker than the others. secured. by screws L15 7u, passing thrmigh the slots `in said cross-bars, two plates, lx 7n, which.

IOO

IIO

To the said cross-bars 7.;3 7;." are extend from just in the rear of the upturned end of the plate K2 to the rear end of the same. Upon top of the plates le 7c are pins k7 k7, which pass through holesin lateral arms kg ks on the standards or posts K K K K.

Upon a line with the curved ends of the vertical side plates, K K', and afiixed to the edges of the plates 7e k, are two vertical ears, k2 k2, having' their forward ends curved outwardly and their lower forward corners turned up sli ;htly,l said ears acting to turn in the last angle fold of the wrapping' material, as shown at 4, Fig'. I6.

The framework of the wrapping' devices above described is capable of being' adjusted to accommodate differentsized articles or packages, as follows: The thumb-nuts 'i3 'i3 and the screws 7J being' loosened, the irons I I may be set farther apart or closer together in their movement, carrying with them the vertical side plates, K K, and the plates k k, thus increasing or diminishing' the width of the delivery-chute accordingly as said irons are moved closer together or farther apart. The web of the irons I I is turned in near the forward end of the same, and upon the outside of the web on each side is secured a block of metal, L, which is substantially triangular in cross-section. Upon top of t-he block L is secured an arm, Z, which projects upward and outwardly, and to said arm is attached a spring', Z2, to the other end of which is secured a plate of metal, Z3, that passes through a slot, Z4, in the web of iron I. A pin, Z5, is fixed in the slanting undei' side of the block 'Ii, and in one position of the plate Z3, as in Fig. (i, its outer edge bears against the said pin. The plate Z3 has a pin, 16,011 its bot-tom, that passes through a triangular or wedge-shaped slot, on, in the head fm of a sliding plate, M. This plate M lies and slides upon the outside of the iron I, and is held in position by a screw, m2, that passes into the web of the iron and through a slot, m3, in a vertical liange, m, near the end of the plate. Upon top of the flange mt and at each end of the same is a lug', m5 m5, and a cross-head, N, upon a horizontal]y-reciprocating rod, N', contacts with these lug's alternately, thus imparting an intermittent reciprocating motion to the side plates on each side. The plate Z"g has a certain amount of lateral playin the slotZ", and is capable of turning on the edge of said slot as on a pivot when its inner and lower edge is pressed upwardly, and by this movement the plate is disengaged from the pin l, and when so disengaged the spring Z2 draws the plate back until its inner edge is just on a line with the inner edge of the slot Z4.

The two positions of the plates Z3 Z3 are best seen in the detail views, G and 7, and the manner in which the same are operated is as follows: The plates l"E Z3, being in the position shown in Fig. U, receive and sustain the package to be wrapped until such time as a table, T, which rises up under the plates l Z3 at certain regular intervals, contacts with said pl ates and lifts their inner ec ges.

This causes the plates to become disengaged from the pins Z2, and they tly'back into the position shown in Fig. '7, thus allowing the article to rest upon the wrapping material, which projects over said table. The table T and the plates Z3 Z3 are restored to their former position by the backward motion of the slide-plates M, the triangular slots n1 acting' upon the pins l and forcing' the plates out through the slots and until their rear edges again engage with the pins Z5 Z5.

O designates. a tiat horizontal apron which is placed in the rear of the pivoted plates Z3 Z3, and is secured to the inner edge ofthe T-iron on one side, projecting' through an opening in the web of the iron on the other side and beneath the bottom of the chute P.

P designates a second table which rests upon the cross-pieces 7L h2, and has a central rectangular cavity, p, that lies under ends of the irons I I. This table P serves to receive and sustain the wrapping material as it is fed forward from the rolls, and at the side of the cavity p are arranged adjustable guides p p', which hold the paper in position over the cavity p while the table is ascending'.

In order to prevent the paper or other wrapping n'laterial 'from sagging' down into the opening p in the table P, I provide two wire forks, p2 p2, which ext-end over said opening while the paper being' fed forward, and which are turned out of the way by appropriatc mechanism when the paper is in proper position. These wire forks are fast to the tops of uprig'ht rods P3233, which are swiveled in the blockp, to which is hinged the first of the hinged plates g, which effect the folding of the first flap of the wrappingmaterial over the top of the article. These rods p3 p3 are square in cross-section, and are each given a quarter-turn, so that they form spirals, and they pass through square holes in arms 195195, projecting' from a cross-bai', p6, which is secured to the tops of vertically-reciprocating rods which carry the racks operating the folder Q, the result of which arrangement is that upon the downward movement of the cross-bar p the wire forks p2 p2 are turned aside from over the opening p, and upon the upward movement of the same the wires are restored to their original position.

One of the features of the present device to which I will here call particular attention is that the weight of the article to be wrapped is utilized to effect a portion of folding of the wrapper, and this is effected by having the article descend through the opening p in the plate P, taking down with it the two sheets of wrapping material which have been previously cut from the strips CZ and e and folding up the sides of the same against the sides of said openin The table T, which has been previously referred to and described as ascending beneath the plates l3 Z3, and after operating the same receiving' the article to be wrapped and the wrapping material, con- IOO IIO

sists of a fiat plate mounted upon a vertical post or standard, t, thatis connected by a pitman, t', with the gear-wheel t2, which receives motion from the mutilated gear B2 on the main shaft B, the table being thus operated by the same mechanism which in the machine described in my before-mentioned patent operated the tilting-trough and its lgilunger.

It being premised that the folding devices are substz'mtially the same as those described in my aforesaid patent, it will be unnecessary to particularly describe the same; but I will now describe the means whereby said folding devices may be adj usted to operate upon paclc ages of di llerent sizes.

It will be seen that what I call the endwing folders,7 which are marked R R in the drawings, are hinged to a skeleton frame composed of the cross-bars R2 R:E and vertical rods R* R", which reciprocate through holes in the table, the cross-bar R carrying an anti-friction roller, w", which travels in a cam-groove, SS, in the wheel B. Another and similar frame composed of vertical posts s2 s2 and cross-bar U, the latter carrying a roller, c5, which engages with a cam-groove, In, in the wheel B', is provided at its upper end with the vertical racks s s, which engage with toothed segments S S, fixed to the pintles of the folding wings R R, which latter are operated by the engagement and (Ko-operation of the racks and segments, while the frames are operated in a di tferential manner under con# ditions and for the purpose designated in my patent already referred to. The rock-shaft G3, which actuates the shears, receives motion from the frame R2 R3 through a vertical rod, g5, connected to the bar R2.

In Fig. S of the drawings I have lillustrated the end-ning folders and the means for adjusting the same. The said end-wing folders, which are lettered R R, are hinged to sliding blocks 'i' fr, dovetailed into slots in the plate r and having on top and at their inner ends lugs i r?. The plat e fr is lformed with a piece, "r3, which is in line with the lugs '12 i, and the lugs r2 fr? are formed with reverse screw-threads, so as to receive a right and left screw, yrl, which passes through them and through the piece r3. The screw tu rnsin the piece l without traveling, and a jam-screw,

fr, serves to fasten the screw r3 when the proper adjustment has been secured. As the toothed sections S, by means of which the plates R R are turned, are fast on the pintle ot' said plates, it is necessary to provide for the difference in position of the same, and accordingly I mount the racks s s, with which the sections engage, upon arms s s', which pass through slots Vin the head of the verticallymovable rods s2, through which said racks receive motion from the cam-wheel land secure the arms in the slots by means of keys .ST si, as shown.

The horizontally-swinging side-angle folders are constructed and operate substantially in the manner shown and described in my previous application, but are made adjustable by the following arrangement of devices:

The folders consist of the horizontallyswinging arms I NV, which are secured at their outer ends to short vertical shafts a n, which pass through slots d5 a in table A and are journaled in blocks n a, which move in dovetailed grooves in the table, the said blocks being adjustable toward and from the edge of the table by screws n2 n2. To the lower ends of the shafts 'nu are secured arms n.3 n3, which have friction-rollers a4 a4, that work in slots n of in a frame, XV', which is mounted on a l1orizontally-reciproeating rod, It, which receives motion from the cam on the periphery of the wheel B. The rod I2 is utilized for the purpose of giving motion to the rod N, which carries the cross-head and the plunger N2, proj eeting out beyond the end of the table A and cormected to said rod by a frame, IW. Operation The article to be wrapped (which is, for instance, a cake of soap) is fed to the table O by the chute P', and is slid forward upon the supporting-plates Z3 Z3 by the plunger N2. At the same time the two strips d e have been fed forward (the lower strip a somewhat greater distance than the oth er) below the cake of soap, a proper length being cut off by the shears. The forks p2 p2 have been utilized to sustain and guide the wrapping material, and are now turned aside out of the way. The table T, arising, releases the plates Z3 Z3, and the soap and the wrapping material descend and rest upon the table T. The latter now descends, and the two sides of the wrapper are 'folded up into vertical position, seen at Fig. lo, by contzlcting with the sides of the opening p in table I). The table T continues its descent until its surface level with the surface of table A. The folder Q now comes into play and folds down the wrapping material at one side, as seen at 2, Fig. l ti. A plunger, V, that receives motion by means of V fromv the cam upon the periphery of cam-wheel B2, now pushes the article along beneath the end ot' plate K2, and the wrappin material on the other side of the soap is thereby folded down over the top. The en d-wing folders now come into play, and the package assumes the shape shown at 3, Fig. 1G, and then the movable side-angle folders IV i, the package then appearing as at et, Fig. lo. The article is then pushed still farther under the plate K2 bythe plunger V, andthe stationary sideangle folders give it the shape shown at 5, Fig. 1G, and the curved ends ot' the vertical plates K* K complete the folding operation. The parts now return to their former position, and the next article is operated upon in like manner.

The manner of adjusting the several parts of the machine has been hereinbefore sufieiently described and need not be repeated.

Having describedmy invention, I claiml In a package-wrapping machin e provided with a paper-cutting instrument, substantially as described, and a series of paper-folding wings, the combination, with said cutting-im IOO IIO
