To all u'mm if may concern:

Be it known thntI I, 'lIIEoDoRE L. CAMP, a citizen of 'the United Stat-es, residing at Chicngo,`connty of Cook, State of Illinois, have invented certain new and useful I|Ii proveniente in PackitIg-liiachiues; and I declare the following to bea. full, clear, and exact .description-of the invention, such as will enable others skilled in the nrt to which xo it. pertains` to-make und use the same, reference being had to the accompanying drawings, which form u part of this specification. My invention relates to machines for auto mntically packing nrticles in boxes, such as I5 cakes of soap, boxes of matches, orlany analogous packages; and it consists in the various constructions, arrangements, and co1nbina- Lione` hereinafter described and claimed.

In the drawings, A indicates the main frame of the machine. y

A' is a Supplemental frme rigidly attaiched 55 to the main frame A. pon one en o the frame A is erected a V:support n w te IW journaled a shaft A2.' Upon the end of this shaft is a sprocket-wheel a', which is continuy ously driven by any suitable Source of power, 6o but preferably by a sprocket-chain, "for the reason that it does not slip, it being essential I that all the parts should be driven in exact relations. This chain is not shown, because the manner of driving is immaterial to the invention, provided it be by exact means, and such constructions are very common. The opposite end of the shaft Ais jonruaied inn 1 W standard a2 and carries at its extren'itynI r'4 crank ci. Pivoted upon the crank-pin ofths 1o crank is a connecting-rudy. The oppositie` end of g in connected to and operates va reciprocntingvblock G8. (See Figs. 6 and 7.) This block reciprocates upon the ways G' G', which are fixed upon the frame 0f the-mtb 15 chine and which are necessarily rigid. The block or crosshezid G8 carries a hook G, pirr-l otcd thereto-end controlled by n. spring g'. Upon the angle of the hook G and projecting therefrom is a pin g. Between the ,ways or gallows-frame G' G' is n stein A, which reci prot-aten perpendicuiarly iu suitable ways. The lower end of this stem carries a rectangular plunger A, as shown in Fig. 7 und nu hereinafter described, of the proper :size t0 85 cover any assignable number of packages to be plnced in the box. Five of these are shown in this ligure, us O, OO, 000, die. i'

Upon the stem A3 is fashioned a spur is", over which the hook G is adapted to engage, the downward reeiprocatious of the crossvbead G8 intermittently drnwingdown the stem A, und thus carrying with it the plunger A4 for purposes hereinafter described.

Upon the guide-frantic is located another guide P10, in which reciprocntes a guard F'. y

This guard projects in clone proximity to the spur F upon the stein A und also in auch relation to tite hook G'thnt the pin g thereon rides n p upon the guard, nnd therefore it prevents the hook from engaging the spur F un til the gunrd ie withdrawn. By this means the continuel rotntion of the nhnft A nml the reciproentionn of the crocchettd do not coma negoce springf', the tendency of which is to restore the guard F8 to the position shown in Fig. 6,'

which is a View looking toward the left-hand of Fig. 7. The arm F7 is fixedly attached to a shaft F6, which is journaled in the sub! frame A' upon either side thereof, as shownl At the left-hand side of Fig. 7 is aat A5. bell-crank a6, attached to shaft F6. This is more clearly shown in Fig. 2. Arranged longitudinally with the 4frame A' and upon the right-hand side of the machine, as shown in Fig. 2, is a crank-shaft F3, which rotates in appropriate bracket -journals at tached to the frame and shown at as as. To this shaft is fastened a finger-arm F4, which is adapted to come in mechanical contact with the outer end of the arm osand depress it, and this depression of the arm cz' by virtue of its attachment to and through the shaft F6 rocks the arm F7 backward, withdraws the guard F8, and permitsthe hook G to engage in the spur F9 upon the stem AB.' The crank-shaft F3 is operated by means of the arm F2 attached thereto, which in turn is operated by a plunger F', the ou ter extremity of which is constantly in contact with the lower end of the arm F2. The opposite end of the plunger carries a diskF. The plunger operatesin ways c in the end of a box or chute FT, into which the articles to be packed O, OO, OOO, dac., are fed, the foremost of which coming in contsctwith the disk pushes it outward and, as shown in Fig. 7, thus operating the stem F', forcing the plunger baci-t against the nspiral spring s, which returns it to its normal position when the means of compression are removed, and thus operating the arm F2. It result-s, therefore, that when the articles are in proper position to be delivered through the'chute to the box.

below they operate the plunger F' and by means of the arml F2 rotate the shaft F3,

which in turn rotates shaft F5 through thel connections, withdrawingthegnard F8. The

hook G thereby engages the spur F9 upon thei stem A3, and it is pulled down by the reciprocation of the cross head G3, carrying the,

plunger,whieh forces the articles to be packedv down into the honeycomb box to the extent of the descent of the plunger A, which is governed by the' throw of the crank a3 upon peated until the compartment of the box is filled, as hereinafter described. Vfheu `filled, there is a requisite that the box shall be movedforward and a new compartment brought forward in order that it may be filled The mechanism whereby this in turn, &c. is accomplished is shown in detail in Figs. 9, 10,'and 11. Upon the upper end of the stem A3 is attached a block H2. Pivoted to this block at h2 is au arln H3. This arm is pivoted to a swinging arm Il, and this actuat-es a shaft H7, to which it is attached. A coutin nation Hsof the arm Iliactuates a springpawl M'. Upon the shaft I1 is fixed a ratchet-wheel H5 of somewhat peculiar construction and in close proximity tothe swinging arm 1114, the shaft H7 forming merely a pivot upon which the swinging arm H4 turns. It does not therefore turn with theswingings of that arm which corresponds with the reciprocations of the stein A3. Upon the arm H4 is fastened a pawl H5, controlled by a spring hs. These engage peculiarly-shaped teeth M M upon the periphery ofthe wheel H6. A springpawl Mzprevents the wheel from rotating in an opposite direction to the arrow,

whereas the reciproeations ofthe arm H4 c0m pel the ratchet H5 to turn in the direction of the arrow through the space of one tooth at each movement. A In order topreventan over throw of the wheel H, there is the springpawlM', which is allowed to engage a tooth when the turning of the wheel is compelled bythe rising of the outer end of the arm H4 and the withdrawal of the arm H5 from contact with the pawl M', the head of this pawl dropping in advance of a tooth, and thus preventing the wheel from rotating beyond the proper position. When the parte are in proper position -for rotation, the arm H3 throws out the pawl M', as already stated, and thus permits the wheel to rotate; but this pawl acts as a back-stop, and the pawl ill2 engagesthe teeth by slipping over itat the same instant at all times, except when the wheel is allowed to rotate it is held by one ,of its teeth being firmly engaged between the back-stop M and the paWl M2. The shaft II7 is journaled in bearings attached-to the frame at H9 H9 and carries at its outer extremity a wheel K, uponrthe outer Vface of which and perpendicular to the plane thereof are pins k k. These pins lift and operate a springarm H', to which is pivoted a connectingr0d S, the opposite end of the rod II' being journaled at h in a standard H.

It is obvious by considering this mechanism thus far described that the crosshead G3, which continually reciprocates, does so without connection with the stem A3 until bythe delivery of articles in the chute to be packed, as shown in Fig. 7, thehook G upon the crosshead engages the stem A3 in the manner dcscribed, and the stem thereby is compelled to descend, carrying with it the plunger A, which also carries down the articles O, O0, OOO, &c., to be packed. Every descent ot IOO IIO

. eeopec 3` the plunger rotates the ratchet-wheel H6 to the distance of one ol"A its teeth, and this actnates the wheel K to the corresponding extent. If, therefore, the pins k are so spaced that five teeth come between theme-in other words, five strokes of the stem .A2-they can be arranged s'o that foreach five strokes ot'` the stem A2 the spring-arm H', carrying the connecting rod S9, will be actuated once. 1f, therefore, there were five layers in a box of packages O, OO, OOO, dac., to be packed, when the ve layers were completed the connecting-rod S9 would be actuated by the mechanism hereinbefore described, and if the connecting-rod S9 be now connected to proper mechanism for actuating a deliyery of the boxes the distance of another compartment it will be then carried forward and be ready to receive another series of packages, which will complete the filling of that compartment, and thus the operation could proceed indefinitely. I will now describe the mechanism which effects this connection and'rcsult. As'shownin Figs. Sand 9, the lower'end of the connecting-rod S9 pivot-ally connects with a pivoted frame R', pivoted to the side bearings of the frame.v The lower side of this frame carries in appropriate ways a reciprocating plunger S, controlled by a spring R, which surrounds the stern of the plunger S and is compressed between a 'fixed part on R and a nut on the plunger-and which tends to maint-ain the plunger in the position shown in Fig. 8; but when the plunger comes in contact with any one of the lugs B7 on the frame of the honeycomb box the spring is compressed and the plunger takes the position shown in Fig. 9. 'The eX- tremity of this plunger comes in contact with a swinging arin d, attached to a rocking shaft D2, properly journaled, and which in turn actuales another swinging arm D2; Fixed thereon, adjustably pivoted and attached Vto the swinging arm D2, isa stein D4, and adjustably attached to the stein D4 .isan arm D8. At the lower end of the stein D4 at Dsisaguideblock and abutment against which impinges a spiral spring D7, held in a case D. The lower end of the stem D4 carries a head D,

`npon` which the spring rests and by which it is compressed. The guideblock D5 being rigidly fixed in the case D, it is obvious that if the case be firmly held in any position the raising of the stem or rod D4 would compress the spring between the guide-block D5 and the head D6. The case D is pivotally attached to a frame S6, which is pivoted at S7 to a bracket attached to the main frame A. In the frame S is journaled a shaft S3, upon which there is fixed a sprocket-wheel S4 at one end and a worm-gear at the other end. The worin-gear intermittently engages in a gear-wheel S2, fixed upon a shaft S15, which is jou-rnaled in bearings in a bracket attached to the frame A. 'lhe spur I)B upon the 'rod D4 carries at its outer extremity by a slip connection controlled by a screw-nnt E a stem D9. This,is pivoted at E' to rock-shaft S8, which is also Vshafts C' C2.

jonrnaled in a bracket upon the inaiu frame. ExtendingV from the rock-sl1aft downward is an opposite arm S2, controlled by a spring E2, which puts a constant tension upon the arnrSi. L'pcn the frame S5 is a block E2, the lower end of the swinging arm S12 at S' being notched to fit the edge of the block, which is so constructed as to be adapted to engage the notch when the worm-gear S5 engages'the worm-wheel S2, as shown in Fig. S, and thus forms a trigger-stop.

To return to Fig. 1l, when the rotation of the pin-wheel K, carrying the pins k k, is such that one of the pins comes underneath the extremityoi' the arm H' the next succeeding partial revolution of the wheel of one notch caused by the ratchet acting on the ratchet,- wlrcel lifts the outer end of the arm H', which raises the rod S9. This in turn raises the arm R', carrying the plunger S, which is instantlyl thrown forward by the spring R. The arm D2 descends by reason of its weight, which had been resisted by the plungerS in a manner hereinafter described. This brings the worin-gear into gear with the wheel S2, and it is locked in that position by the trigger-action of the arm S2 acting upon the block E2 on the frame SF. The sprocket-wheel S", being continuously driven, at once commences to rotate the wheel S2 and continues its rota-- tion so long as the worin-gear is in position.

It will now be necessary to turn to another feature of my invention.

In Figs- -1- and' I have shown the box which I employ and which has heretofore been designated as a honeycomb box. It consists of vthin nic-tai sides and has an open bottom. In the box and dividing it into equal spaces are two partitions B B2. Upon the upper end and one edge of the box at right angles to these partitions is located a bar B5, firmly attached to the wall of the box'. Upon the bar B5 are firmly attached lugs B7 B7. Upon the under side of' the bar, which projects out beyond and over the Side of the box, are couilter-lugs B" B6. 'The wall of the honeycomb box is marked B". Rivet'ed to the partitions B and B2 and to two sidesof the walls of the box are thin sheet-metal springt-i B3 B2. They are shown in Fig.`5 in section,' with the side ,wall of the honeycomb box removed, leaving the ledge Bsand the cross-walls with springs. (Shown in section.) The springs are shown in their normal position. The honeycomb box fits inside of a common packing-box 152, (also shown in Fig. 5 in section,) from which it is removed after the delivery of the whole as- Y semblage containing the articles packed from the machine, as hereinafter stated. .Tournaled to the main l'rameof the machine A are 'lhese each carry va. pair of sprocket-wheels C3 C, it being understood that they are alike, one each upon opposite sides of the machine, a pair upon eachshaft. Upon the shaft- SL" are fastened a pair of sprocket-wheels C5 C, each of said pair C5 C being upon the same shaft as the worin gearlinks thereof lugs or projections O7 C7.

pair of the sprocket-wheels C5 C6 are carrying sprocket-chai ns C,which intermittently travel .in the direction of the arrow shown. in Fig. 1,

while carried by the wheel C2 and the opposite oneof each pair of sprocket-wheels C5 C6 is another pair of sprocket-chains C2, which also intermittently move, as hereinafter stated. 'l`hesesprocket-chainshave'attachedtoproper The upper part of the band of the sprocket-chain travels upon ways C2, formed on the main frame. The oiiice of these sprocket-chains is to carry the packingbox already described, in which is inserted the honeycomb box, as shown in Fig. 2. The sprocket-wheel Si being put continuously in motion operates the worm S5, as stated. This in turn when engaged with S2 operates the wornbwheel S2 and by means of the sprocket-wheels C5 Ci on the shaft S75 of the worm gear-wheelldrives' the sprocketchains in the direction indicated by the arrow in Figs. 1 and 2. So iongas the worm S5 is in engagement. with the worm gear S2, the sprocket-wheel S4 being continuously driven, it follows that the sprocket-chains would be also continuously driven whenever the wormgear is in connection and would stop whenever the worm was disconnected. This connection between the worm and worm-gear would be established at all times except'under conditions hereinafter stated. A box being placed upon the ways C8 would by the movement o? the sprocket-chains, as described, be finally caught andiactuated by a pair of the projections upon each chain. C7 C7. It would be carried forward to a position underneath the plunger A4, when the foremost lug B7 (see Fig. 4) would come in contact with the plunger S, thus compelling the plunger to move against the arm d and throw the rock-shaft D3 and the arm D2, raising the stem D4, causing the arm D8 to slide upon the stem D9 until it engaged the' unt E, and.

until it did engage the nut E the trigger-arm S would be in contact with and over the block E, whereby the arm S6, shaft S3, and worm S5 would be held down in contact with the wheel S2, as hereinbefore described. During the time of the raising of the arm D2vand vits connecting-stem the spring D7 is compressed by means of the nut D6 on theend of the stem D4, and when the arm D8 comes in contact with the nut E a continuingl upward movement operates the arm E' and the rock-shaft SB, and thus disengages the trigger S from thestop-block E2. The instant of disengagement results in the spring D7 act.- ing against the plug D5 in the case D and raises, through the connection D12, that end of the frame S6 which carries the worm S5, thus instantly disengaging the Worm-wheel i' rom the worm-gear, and necessarily at 'that instant the further progress of the box is arrested bythe stoppage of the driving sprocketchain. This is shown in outline in Fig. 9.

efeobee Upon the side of the main frame at It' is pivl oted a dog L, controlled by the spring L2, also attached to a bracket upon the main frame. The oiiice of the dog L is to instantly engage the under lug B6. Thus the box is locked in such receiving position between the lugs B7 and B5. This dog and spring are shown in dotted lines in Fig. 9. `The position of the box is nov;7 such that its advanced compartment is directly underneath the plungerA and registers with it. Underneath the plunger A4 is a chute'or framework. (Shown in section in Fig. 12, also in Fig. 2.) Leading thereto from the side of the machine is a trough P6. This trough is for the purpose of taking into the machine the 'articles to be packed, and it leads directly into the chute P7, which is also shown in section in Fig. 12. The lower edges of the chute P7 at p p are broadened slightly outwardly, and pivoted thereto are narrow 'strips' P', controlled by springs p' p', which keep the strips P' P' horizontal and extending inward from the inner wall of the chute sutiiciently far, as shown at P2192, to 'forma support for any article therein to be packed, an article being shown in Fig. 12 as Q. These spring ledges or strips P' P' form a continuation of the bottoni of the 'trough P6,and asarticles are fed regularly into mechanism whereby 'the reciprocation of the cross-head. G3 is enabled to force down the plunger A4, which coming in contact with the upper surface of the articles that are in the chute forces those articles below the chute, opening out the ledges P' P' to permit their passage into that compartment of the box which is directly underneath the chute and registers with it. Instead of being forced clear to the bottom of thebox they are held by the spring sides of the honeycomb box, so

that on the stoppage of the downward motion of the plunger the articles are held in the position as left by the plunger or in proper position. the upward motion of the stem A3, which is done by a spring N, attached to the top of the frame at N', the articles remain in position until the second layer is forced down. Filling the second layer forcesthe first layerjust the distance equal to the thickness of the first layer toward the bottom of the box. The num ber of layers in the box being proportioned to the distance between the pins k 7:, upon the wheel K, attached to the shaft of the ratchet Y wheel HG, it follows that, say, four strokes of the plunger will be made and four layers of articles to be packed will be forced into a compartment before the mechanism set in motion by the next succeeding pin--to wit, the swinging arm H', the stem H2, and its On the plunger being withdrawn by' upon by the mechanism hereinbefore described the sprocket-chains C and C9 will be set in motion'until the next lug .3T upon the honeycomb box is brought into contact with the plunger S, attached toor connected with the swinging arm R", and this connection will again detach the worm-wheel andv worm and the box will stop to enable the second ,corre partment of the honeycomb box to be filled in the manner already described, and this` process is'repeated so long as there are any boxes of the kind and construct-ion carried by the chain C. It follows, therefore, that so long as boxes of this description are fed into the machine upon the ways and adapted to he' conveyed by the sprocket-chain C and delivered by the sprocket-chain C9 and so long as articles to be packed are fed into the chute P5 in the proper manner the compartments will be regularly filled in orderand the boxes delivered atthe rear of the machine, from whence theyare taken ofi" in any convenient manner, the honeycomb box is drawn from inside the packingbox, and articles to be packed pass through the bottoni of each compartment of the honeycomb box and remain in the packing-box in proper form for the closure of those boxes.

It is obvious that, while Ihave shown tive articles in a layer and four layers in a cornpartment and three compartments in a box, by proper adjustment any number of articles in any number of layers and any number of compartments could be used, provided the requisite corresponding adjustment o the mechanism was made. It is also obvious that if no articles to be packed aro fed into the machine and if boxes were placed upon the ways as described they would simply' move forward until they were stopped by the lugs, and if no articles were fed in there would not be any means whereby the unlocking of the mechanism which' prevents the motion'of the sprocket-ehains would be secured, and therefore the movement of the boxes would be wholly arrested and no further movement could take place. Hence it is impossible for any jamming or other disarrangement of the mechanism to take place by reason of placing boxes therein and attempting to feed them into the machine without feeding in the articles. In other words, the motion of the box depends upon thefilling of the compartments by articles to be packed, and unless this takes place all mo tion on their part is arrested and held in posi t ion until the articles are fed in proper form.

It is obvious the articles might be fed into the machine by hand or by any machine which wouldfeeil them regularlvand in correspondence with the operations of the machine.
