Application filed A st 14,1897. Serial Noi 648,305. (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN H. FELMLEE, a citizen of the United States, residing at Pitts; burg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machines for lVrapping Soap, Oaramels, and other Articles of Uniform Size; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, andto the letters of reference marked thereon, which form a part of this specification. v

This invention relates to certain new and useful improvements in wrapping-1nachines, and especially to mechanism for wrapping bars of soap, caramels, and other articles of uniform size; and it is my aim to provide a machine which will receive the cakes in, rapid succession and deposit the same singly into a suitable carriage, which at a predetermined moment is automatically caused to carry the same to another part of the machine, where a sheet of wrapping-paper, which has been previously cut of a proper size by a suitable cutting mechanism, is'in readiness to receive the cake of soap, which is held in a fixed position while folding-arms are actuated to wrap the sides and ends of the paper in regular order, after which the cake is forced out through a trough, in which operation the remaining flap is wrapped, and the cake forced along in the trough to make room for the following ones, which come through in rapid succession.

The invention relates, further, to the provision of a carriage having a bottomless receptacle provided at the ends thereof with spring-flaps, which are designed to receive a cake of soap and hold it while the carriage is traveling to a location at which the cake is automatically ejected through the bottom ofare downwardlyfolded, means being provided to return the wrapping-arms to their starting positions without interference in any way with one another or of other parts of the operative mechanism. In connection with the above is provided means for forcing the cake of soap, with its two remaining flaps unfolded at each end, through a trough having inclined grooves, adapted to rec eive the last flap to be folded at the bottom, and the cake is forced into the end of the said trough by means of a plunger, which is actuated while the top and end wrappingarms are in the position that they assume in wrapping the paper, the last flap being folded as the cake is forced into the end of the trough, having diagonally-disposed slots to receive the said flaps, the said flaps being folded as the cake is forced into the trough, and the flaps traveling in the inclined slots are caused to be folded against the ends of the cake when the slots have been passed by the cake, which cake is forced along bya following cake, the same passing through in rapid succession. I

The mechanism for producing the above effects will be clearly understood when considered in connection with the drawings formin g a part of this application and the description which will herein after appear, and which sets forth the operation of the invention,

which will be clearly defined in the appended claims.

' The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts throughout the several views, in which- Figure 1 is atop plan view of the wrappingmachine Fig. 2 is a side elevation of the operative mechanism of the wrapping device, showing table or support in section. Fig. 3

is a sectional view on line 3 3 of Fig. 1. Fig.

ously placed, this view showing the carriage with the cake contained therein and the ejecting-plunger raised above the cake in readiness to be lowered to release the cake from the carriage. Fig. 7 is a perspective in detail, showing the cake after it has been ejected from the carriage and deposited between the ends of the troughs, the folding blades being shown in their position previous to the folding of the side flaps. Fig. 8 is a detail showing the next stage of the folding of the soap, in which the two side flaps have been folded one upon the other. Fig. 9 is a detail View showing the cake held in its folding position, with the side flaps held down and the end-folding arms bearing against the ends of the cake, with opposite edges on one side of the cake folded against the ends of the bar of soap. Fig. 9 is a detail view of a cake of soap with the wrapper portion folded in the shape that the-wrapper assumes when operated upon by the folding mechanism shown in Fig. 9. Fig. 10 is a detail view showing the side and edge folding members holding the flaps against the soap with the third set of wrapping-arms, which have been forced down against the upper flap on the broad side of the cake, and holding the cake in the position from which it is to be ejected into the end of the trough having the side strips with the diagonally-disposed slots, this View showing also the cake as it starts into the trough, the lower flap just entering the inclined slot on one side. Fig. 10 is a detail View of a cake of soap, showing the stage of the wrapping as the cake is forced into the trough. Fig. 11 is a detail view of a cake of soap, showing the wrapper completely folded.

Reference now being had to the details of the drawings by letter, A designates the. framework or table upon which the mechanism for wrapping soap is mounted. The cakes of soap are previously placed in the inclined trough B, with their broad faces against thev bottom thereof and their edges adjacent to one another. Opposite the open end of the said inclined trough is disposed the open cakereceiving end 0 of the carriage C. The said open receptacle, which is bottomless, is in this position when the cake of soap slides down by gravity and drops into the receptacle (3, after which the cake is in readiness to be fed forward by the carriage into the position in which to receive the wi-appingpaper. At each end of the said receptacle 0 are the springflaps O and G which are secured at their upper ends, as at c, to the upwardly-extending ends of the said receptacle, and their free ends are slightly forwardly disposed, so as to receive and hold the cake while it is being conveyed to the proper position to receive the wrapper. The lower end of the spring-fiap 0 it will be observed, is slightly longer than the spring-flap 0 as clearly shown in Figs. 3 and 4: of the drawings. This extended end of the flap G isprovided so as to abut against the end of a portion C of the table, which causes the spring to be forced back against the end of the receptacle, and allow the cake to fall down to thelower limit of the free end of the spring (J and rest against the portion of the table, and after the carriage starts in its forward movement, after the spring-iiap C is free from the edge 0 of the table, the said flap will act in conjunction with the spring-flap C and hold the cake in a horizontal position while it is conveyed by the carriage to its position adapted to receive the wrapping-paper. This carriage G is held on a portion of the table and guided by the screws 0 in the slots C and has on its under side an arm C to which one end of the anglelever D is loosely pivoted, as at (Z. The carriage has upright sides C one of which sides, as the carriage is fed forward, comes in front of the open end of the inclined feeding-trough to prevent the cakes leaving the trough until one cake has been carried forward, wrapped, and the carriage returned to receive another.

J ournaled in the framework of the table is the operating-shaft E, to which power is trans mitted in any suitable manner, and on said shaft is keyed the operating-wheel E, which has about a portion of its circumference a series of teeth 6, which in the revolution of the wheel are designed to mesh with the cogteeth e on the pulley E to cause an intermittent rotation to the shaft E which is journaled in suitable bracket-arms E depending from the under side of the table. Said shaft E has keyed thereto a sprocket-wheel E, on which works the sprocket-chain E, which passes over a sprocket-wheel E, mounted on a shaft E which is journaled in the upright istandards E and on said shaft E is a frictional roller E", between which and a second frictional roller E the paper F is fed, which ipaper is held'on a roll mounted on a shaft carried on the brackets G at the end of the liable. The said frictional cylinder E is jmounted on a shaft E, and said shaft has a l geared wheel E at one end, designed to mesh iwith a similar geared wheel at the end of the jshaft E whereby the two wheels are caused i to rotate together and feed along the sheet of paper.

The paper F as it is unwound from the iroll first passes over the cylinder II, which lmay contain type provided for the purpose of printing the paper, if so desired, and H is ,a pressure-roller which is mounted in the iupper ends of the standards II and provided with a suitable spring 7L, whereby the desired pressure maybe brought to bear on the paper, which is forced against the type to receive the impression. Underneath the cylinder II is an ink-cylinder H mounted in a suitable bracket H", and against which cylinder the type may contact in order to properly ink the same. The paper which has passed over the printing-roll and thence between the frictional rollers and fed a sufficient distance through, which has been predetermined and which will afford a wrapping-paper of a suitable size, is now ready to be cut. The cutting mechanism consists of the blade I, which is pivoted at one end, as at I, to the first of the uprights E and is disposed at an angle and normally held in this position by any suitable means, as by a spring which may be attached to the said blade. To the free end of the said cutting-knife is connected a cable 1, which passes down over the pulley 1 and is connected to the end of the lever K, which is pivoted at K to the under side of the table.

The lever K has pivoted to its free end a trip-lever K, which has a shoulder adapted to strike against a shoulder on the said lever K and cause the latter to turn on its pivot when the arm D, which draws the soap-carriage forward, strikes the said trip-lever, and on the return movement of the soap-carriage the trip-lever joint will break and allow the arm D to return to its starting position without moving the lever K. As the lever K turns upon its pivot the end of the knife, which is connected to the said lever by means of a cable, will be pulled down and a strip of paper will be cut from the roll, as will be understood.

Motion is imparted to the carriage carrying the cake of soap by means of lug E coming in contact with a lug E on the lever E as the wheel E makes a revolution. As the lug E comes in contact with the lug E on the lever E, which lever is connected by a link E to the angle-lever D, the said lever E, which isloosely j ournaled on the shaft J, is caused to be depressed and through its connections with the arm 0 of the carriage causes the carriage to advance forward, as will be readily seen. As the carriage advances the arm D strikes the lever K and through itsconnections with the cable to the knife I causes the knife to be depressed and cut off a strip of the wrapping-paper, and after the said lever K has passed the arm D the knife I will assume its normal position. The carriage continues its forward movement until the lug E has passed the lug E and immediately before the lugs pass each other the cake of soap in the bottomless portion of the receptacle holding the same is directly over the piece of wrapping-paper, in which position the cake of soap is in readiness to be ejected from the carriage. This operation is effected by means of the lever L, which is pivoted at L to a portion of the framework of the. machine and carries at its free end a plunger-block L This lever L is connected by a link L to one end of the anglelever L, which is pivoted at Z to a bracket on the under side of the table. The outer face of the wheel E is provided with a lug M, against which the free end of the angle-lever L strikes at every revolution of the wheel E. As the said lug strikes the an gle-lever it causes the lever L to be depressed and the plunger L to strike the upper broad face of the cake of soap and force it through the bottom of the receptacle of the carriage onto the paper and down between the ends of the troughs N and O. This lever L may be provided with a spring L for returning it to its normal position after theangle-lever has struck and passed the said lug M. The cake having been released from the carriage-receptacle,the carriage returns to its starting position after the lugs E and E have passed each other, the said carriage being returned to its starting position by a spring 0 The cake, now being seated between the ends of the troughs N and O and on the piece of wrapping-paper, is now in readiness for the folding over of the upturned flaps onto the broad face of the cake of soap. This is accomplished by means of blades P and P, which are of the general shape shown in the drawings and clearly seen in Fig. 5, each having an elongated slot 19, which is angularshaped, and each blade has an aperture 1), through which a pivot passes, pivoting each of the folding-blades to the stationary table. Running in the said grooves are the lugs P mounted on the carriage, while near the forward free inner edges of each blade are the scalloped recessed portions, which are cut away to allow the end-folding arms or levers to be depressed over the ends of the bar of soap which is being wrapped. It will be noted that the angle-shaped slot in the blade P has its angular portion, as at P, a farther distance from the free end of the said blades than the angle P in the blade P. This is provided to allow the blade P to turn on its pivotal point slightly in advance of the turning of the blade P for the purpose of turning the under flap first, as shown plainly in Fig. 8 of the drawings. It will be noted that as the carriage is drawn forward and the lugs P travel forward in the elongated angle-shaped slots the free ends of the folding-blades will be thrown outward by reason of the said lugs traveling from the points P and P in the inwardly-inclined portions of the said slots. When the soap has been deposited from the carriage and the carriage returns to its first position, it will be observed that the lugs, traveling back with the carriage,will cause the blade P to fold over the lower of the two upper flaps of the wrapping-paper slightly in advance of the folding of the upper of the two flaps, by reason of the distance from the free end of blade P to the angled portion of the slot being shorter than in the blade P, the length of these apertures and the location of the angled portion having been carefully predetermined in advance with a view of having one blade act slightly before the other, for the purpose above described. When the carriage has been drawn back to its starting position, the two blades will have folded over the upper flaps, as shown in Fig. 8 of the drawings. The next step is to fold in the edge flaps, which is done while the upper flaps are being held down by the blades P and P in the following manner:

Loosely journaled on the shaft J is a lever Q, the free end of which is designed to be tilted by coming in contact with the end of the cam Q, 011 the wheel E at each revolution of the said wheel, the said lever Q, being held down until the end of the lever passes the opposite end of the cam. Pivoted to the upright posts of standards E are the levers R, which have secured at their outer angled ends the L-shaped links R which are laterally adjustable on the angled ends of the said levers R, as shown clearly in Fig. 1 of the drawings. Riveted or otherwise secured to the said L-shaped links are the upper folding members R which have their lower ends rolled up and outwardly bent. Sis a link, the upper end of which is pivoted the standard F. at S, there being an elongated slot in the center of the said link to allow a slight play between the pivot S and the said link, while the lower end of the link is pivoted to an ear S on the lever S there being left a slight play between the said ear having an elongated slot and the pivot S T is a link which is bent at an angle near its upper end and connected to lever Q, at its lower end and at its upper end with the lever R. The said lever S is forwardly extended, bent at an inclination slightly inward, and thence again at right angles to the main portion of the said lever, and carries at its end a folding membenS there being two of the said levers S and members S of the same construction provided on opposite sides of the machine. Secured to the table of the machine on opposite sides of the feeding mechanism are the lugs S, which have apertures through the same, the outlines of which apertures are 011 the are of a circle, so as to allow the inclined portions of the arms S to pass through the same and be guided therein. The connection between the arms S and the pivotal pins S is somewhat loose, so as to allow both a lateral as well as a forward movement to each of the arms as they are caused to be driven forward in the act of folding in the edges of the wrapping-paper about the soap. This movement of the edgewrapping members is caused to take place slightly in advance of the downward tilting of the wrapping members R through the medium of the link T, which is connected with thetlever Q, and which latter is actuated by means of the cam on the wheel E engaging with the end thereof as the lever Q is depressed, and with it the link T, connected with the lever B. It will be noted that the links S will be started in their forward movement and carry with them at their lower ends the edge-wrapping members, which will have folded in the edge flaps before the side-foldin g flaps or members R reach the upper edge of the cake in their downward movement against the end flaps.

Fig. 9 of the drawings shows the two end edge flaps folded in on the ends of the cake, the folding-blades P and P still holding down the flaps on the broad side of the cake.

In Fig. 10 are shown the three sets of folding members held against the cake and the cake in readiness to be forced from under the said members and into the trough N, adapted to receive the cake and to fold the two remaining flaps. As the cake leaves the position shown in Fig. 10 the wrapper is folded in the condition shown in Fig. 10 of the drawings, with one side and the under flap yet to be folded. After the two end-folding members are brought against the wrapping-paper to hold it against the paper the plunger-rod U, which is mounted on the upper face of the table and pivoted at its rear end to the arm or lever V, is actuated to crowd or force the cake from under the said folding members. This movement is accomplished by means of the lever V, which is a part of the arm or lever V, coming into contact with the lug M as the wheel E is rotated in the direction of the arrow. As the said lug M strikes the lever V the latter is depressed and the plunger is driven forward against the edge of the cake and the edge flap of the wrapper comes in contact with the side N of the trough,which causes the said flap to be folded against the end of the cake, while the under or last flaps to be folded of the wrapper enter the slots N in the side walls of the trough N, as shown in Fig. 10 of the drawings. As the plunger U, which is guided by the screws U, is driven forward against the edge of the cake of soap the same is caused to enter the trough, with the end flaps extended, through the said slots N, and as the cake advances the said end flaps pass up the inclined portion of the slots, and the same are folded against the end of the cake before the flaps reach the upper margin of the said slots, and the folding of the cake will thus be completed.

After the plunger has forced the cake of soap into the end of the trough the levers V and Q will have left or passed by the lug M and the end of the cam Q, respectively, and springs V and V are provided to return the said levers to their starting-point, when the wrapping members S and R will have returned to the position shown in Figs. 1 and 2 of the drawings in readiness to fold the next cake in succession. As the cakes are discharged into the trough they are forced out by one crowding on the other edgewise.

When it is desired to adapt the knife cutting apparatus so as to cut the wrapping-paper of different sizes, means may be provided, of any suitable construetion,whereby the knife may be set farther from or nearer to the frictional rollers, this adjustment being provided in the slot 1 Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-- 1.
