SPECIFICATION forming part of Letters Patent N 0. 622,038, dated March 28-, 1899.

Application filed December 30, 1897. Serial No. 664,630. (No model.)

. To all whom it may concern:

Be it known that I, SYLVANUS E. DAVIS, a citizen of the United States, residing at Newark, in the county of \Vayne, in the State of 5 New York, have invented an Improved Machine for Making Egg-Carriers, of which the following is a specification, reference being had to the accompanyingdrawings.

My invention relates to a machine for form- |o ing the egg-carriers described in the patent of A. J. Baker, No. 5,567, dated September 3, 1895.

My improved machine is fully described and illustrated in the following specification and the accompanying drawings, the novel features thereof being specified in the claims annexed to the said specification.

In the accompanying drawings, representing my improved egg-carrier machine, Figures 1 and 2 together constitute a side elevation of the machine, Fig. 1 showing the paper feeding and fulling end and Fig. 2 the forming and delivery portion. Figs. 3 and 4: together constitute a plan view of the machine.

Figs. 5, (3, and 7 represent some of the fullingrollers provided with circumferential fullingribs gradually increasing in number from the center outward. Fig. 8 represents one of the fulling-rollers and the fulling-drum in section. Fig. 9 represents a finished egg-carrier. Fig. 10 is an edge view of the same, partially broken away. Fig. 11 is a section through one of the journals of one of the revolving drums, showing the manner of introducing Fig. 12 is a side view of the cutter and its driving mechanism.

The egg-carrier made by myimproved machine is represented in Figs. 9 and 10, the first showing the carrier opened and the latter 4o closed or doubled up ready for use. These crates are manufactured from any suitable.

wise caused to adhere together, fulled longitudinally, and then subjected to the pressing and drying operations.

In the accompanying drawings, A A represent the rolls of paper, which are supported on any suitable framework so as to revolve freely, anysuitable brake or other device being employed to maintain the requisite tension on the paper. From the rolls the paper passes around suitable guide-pulleys B B 13 B and thence to a pasting-roll O, by which any suitable adhesive material is applied to the inner surface of one of the sheets, and thence the paper is led to a guide-roller D, by which the sheets are caused to adhere together more or less completely before being submitted to the operation of the fulling device E. As fed into the machine the sheets of paper are so made or prepared that they are fulled or slightly corrugated transversely, and they are f ulled longitudinallyby the fulling device E, which produces longitudinal corrugations in the paper, adapting it thereby to the operation of embossing or forming out the receptacles which are ultimately designed to hold the eggs. The methods of producing paper with the corrugations transverse to its Widthare now well known and need no description, such paper being furnished on order by many different factories.

The fulling device consists of a grooved drum F and a series of fulling-rollers 1 3 5 '7 9, which produce the longitudinal folds or corrugations in the paper in a gradually-progressive manner, beginning at the middle of the sheet and extending from the central line toward the edges. From the roller D, where the two sheets of paper are caused to adhere together, one having been pasted or glued by the roller 0, the paper passes between the grooved fulling-drum F and the series of fulling-rollers, which produce the longitudinal corrugations. The first of the fulling-rollers, 1, Figs. 3 and 5, produces a central longitudinal crease in the paper; the second, 3, Figs. 3 and 5, makes three creases, one on each side of the crease produced by the first, gradually drawingin the paper from the edges to the center. The next fulling-roller, 5, Fig. 6,

adds two creases, one on each side; the next, 7, Fig. 7, adds two more, and so on in succession to any number of creases required by the width of the paper. Each successive f ulling-roller holds and retains the creases made by the preceding roller or rollers. The successive fulling-rollers each add two creases, one on each side, to the creases produced by the previous rollers, thus gradually narrowing the paper from each edge inward until for a sheet. twenty-three inches wide I have used in practice a last fulling-roller capable of producing seventy or more longitudinal creases in the sheet.

The grooves in the falling-rollers may be of any suitable dimensions-say one-quarter of an inch wide and of somewhat less depth. The grooves in the fulling-drum will correspond,with an allowance for the thickness of the paper-say one-twentieth of an inch, more or less, as required. The arrangement will be understood from Figs. 3, 5, 0, and 7, in which the first of the series of falling-rollers is shown, and in Fig. 8, which gives a partial section of the fulling-drum F. The fulling-rollers 1 3 5 7 9, &c., are supported on the shafts II, which revolve in suitable relation with the curved surface of the fullingdrum in journals in the arches I 1, supported by the longitudinal side frames of the machine J J. The fulling-rollers are driven by the friction of the paper against them. The arches are supported in any suitable way such, for instance, as by being secured to the cross-bars K K. Suitable brackets L, arising from the side frames J J, support the shaft M of the falling-drum F and the crossbars K K. In passing between the fullingdrum and the fulling -rollers the paper is gradually creased from the center outward, narrowed and drawn in on the edges, and putinto condition for the subsequent operations. It will be understood that this fulling device, consisting, essentially, of a grooved fulling-drum and a series of fulling-rollers successively increasing in the number of fulling ribs or flanges around them from the center outward, may be constructed in many other ways and that such device is capable of use for purposes other or different from that herein described.

From the fulling-drum the paper, longitudinally fulled or corrugated, passes around the rollerN, Fig. 1, and thence upward around the drum 0, Figs. 2 and 4, which is provided with male dies of a form adapted to give the paper the proper shape for receiving and holding the eggs. The male and female dies used in my machine are made of a form adapted to produce in the paper passing between them suitable semi-egg-shaped eoncavities, so that when the paper is cut into suit-able lengths and folded on itself f ull-egg-shaped recesses are inclosed between its sections, adapted to holding and carrying the eggs. The paper passes around the drum 0 and between it and the female drum P, which is provided around its periphery with female dies of suitable form, and by pressure between these two drums it receives its first shaping or embossing at about the point Q, Fig. 2. Thence the more or less completely embossed paper passes around the drum P and is again subjected to the action of male dies on the drum R at about the point- S, from which it passes around the drum R and is delivered to a suitable cutter U to be thence discharged in condition, when folded, (see Fig. 10,) for use as egg-carriers. The drums employed are cylinders of cast-iron with heads and suitable hollow journals, with the male or female dies bolted to their peripheries in any suitable way. The drums are made of sufficient strength to sustain the pressure of the steam used for heating them, which need not exceed twenty pounds pressure. The hollow journals permit the introduction of the steam and the discharge of the condensation. The dies may, however, be formed directly on the surfaces of the drums or produced in any other suitable or preferred way. The female drum P and the male drums O and R are heated, so that the paper is driedas it progresses onward. While the manner of work v ing these drums may be varied and several drums may be arranged to act 011 the paper in succession against the female drum, I will describe more particularly the construction of the machine represented in the drawings, and which I have found satisfactory in practical use. It will also be understood that two or more female drums may be employed to coact against a single male drum, the requirement being the gradual or successive formation of the recesses in the fulled paper. From the driving=shaft T, Figs. 2 and 4, power is transmitted to the various drums by the pinion V, Fig. 2, gear IV, and gears X and Y. The uprights Z Z support the shafts of the drums P and R. An extension A supports the drum 0. From the gear Y the fulling drum F is driven by the gears O 0 as shown in Figs. 1, 2, and 3. The paste-roller C is driven from a policy on the shaft M of the fulling-dru m F by the belt E orother suitable device. The uprights or standards Z Z are provided with ways 11 11 on which the blocks L slide, beingforced downward by the springs M, so that the drum R is capable of a slight amount of adjustment relatively to the drum P. The shaft N of the drum R revolves in suitable journals in the blocks L.

O is a cross-bar which is adjusted up and down on the ways ll H by the screw P, th readed through the cap R.

Any suitable stops may be employed to limitthe downward movement of the blocks L and the drum R, or, as in the construction shown, the cross-bars O are supported on collars on the lower ends of the screws 1 and the blocks L are attached to their corresponding cross-bars by the bolts Q, which permit these parts to approach each other,.but limit the distance to which they can be separated. Provision is made in a similar manner for the 6am a adjustment of the drum relatively to the drum P by the ways H H on the frame A the thickness of the papersuch, for instance,

as the employment of weights instead of springs.

S is a paste-trough in which the pastingroll C revolves. Any suitable scraper or doctor may be employed to regulate the amount of the adhesive material applied to the paper, and the roller T is used to keep the-paper in contact with the paste roll. A revolving brush or any other suitable device may be used to apply the paste or glue to the paper. The rollers over or around which the paper travels-such as B, B, D, and N or any of themmay be slightly crowned or enlarged in diameter at the centers of their lengths to cause the paper to travel in the proper course, as has long been practiced for similar purposes.

The mechanism for driving the cutter to cut off the embossed sheet at any particular or required point may be arranged or constructed in any suitable or preferred way. In the accompanying drawings I have represented a rotary cutter; but it will be understood that a reciprocating or other cutter properly timed may be employed. The rotary cutter, however, operates in a satisfactory manner, has been thoroughly tried, and I will proceed to a description of it as represented in the drawings. The shaft U of the rotary cutterblade U is supported in suitable journals in arms attached to the side frames Z Z, which arms also carry a plate V, down which the embossed sheet is fed to be cut off at the proper points by the knife passing close to the shear-block W. The cutter makes a complete revolution at each cutting operation. It is driven from the gear Y, bolted to the gear X, by the gears and pinions Z Z Z Z The gear Z is mutilated or segmental, and the pinion Z is provided'with a stop-face which bears against the smooth portion of the periphery of the gear Z so that the cutter remains stationary until the teeth of the mutilated gear engage with those of' the pinion, when it revolves quickly to effect the cutting of 'the embossed sheet. The pinion may be provided with a pin or lug and the segmental gear with a long tooth to start the cutter in motion, or any analogous device may be used. The outer face of the knife is curved, so as to permit it to run close to the shear-block.

Fig. 11 is a longitudinal section of one of the hollow journals of one of the drums, through which steam is introduced and the condensation discharged. D D is the steaminlet pipe, and E the hollow journal of one of the drums, as R. F represents a suitable gland or packing-box, and I a ring secured by screws and bearing on a collar on the tube D which passes through the hollow journal. J 2 is a block,- into which the pipe Dis tapped and through which the discharge pipe K passes. The discharge-pipe K extends inside the drum and is connected with the vertical pipe K which reaches nearly to the lowest part of the interior of the drum. The steam enters through pipe D and the con densation is discharged through K K ,.as indicated by the arrows. The supply and delivery pipes, connected, respectively, with D and K are extended laterally to a sufficient distance to permit by their flexibility the adjustment of the drums.

The general form of the improved egg-carriers made by my machine will be understood from Figs. 9 and 10. It will be seen that in the form shown each of the egg-shaped semiconcavities Q is provided with a central rib or enlargement N formed by the dies at the same time with the embossment of the paper. Theseribs servea useful purpose, since when a series of the carriers are stacked up in a suitable box or case they abut against each other and serve to relieve any shock or jar, thereby assisting in preventing the breakage of any of the eggs; but they maybe dispensed with and the dies arranged to form simple oval or egg-shaped concavities in the paper.

In order to facilitate the folding of the formed sheet on itself to form the finished carrier shown in Fig. 10, I make a central V- shaped rib V Fig. 4, on one of the drums and a corresponding groove on the opposing drum, so that the paper in passing through between these drums is longitudinally creased or grooved, as indicated at W Fig. 9. This permits the formed sheet to be readily folded on itself, so as to produce the complete carrier. Any suitable device may be employed for securing the edges of the carrier together.

The paper is drawn through the fulling device and unwound from the stock-rollers by the revolution of the die-drums; but it will be understood that any suitable rollers or other devices may be employed for these purposes. Thus a pair of pulling-rollers, running at the proper speed, may be applied to the paper as it leaves the stock roller or rollers for'the purpose of unwinding the same. The pulling or feeding devices may act on the edges of the paper only, as in cases where the fulled paper is to be subjected to the action of reciprocating embossing-dies. When a single web of paper is used, it is desirable to moisten it by any suitable device before it goes to the f ullin g mechanism, a result which is secured by the application of paste or adhesive material when two or more webs are used, since it will be understood that by proper arrangements I can work three or more combined webs through my machine. Under certain circumstances the friction of the driven fulling-drum will be sufficient to feed the paper. Also the paper in some constructions may be f ulled from one edge to the other by a suitable fulling-drum and suitably-arranged f ulling-rollers. It will be understood also that a rotary drum with male embossing-dies implies a corresponding drum with female dies, and vice versa, and that both these constructions are within the contemplation of my invention. Any suitable shape may be given to the dies on the embossing-drums, so that my invention is applicable to the making of embossed products different from the eggcarriers herein shown. The folding of the embossed sheets is incidental merely to the particular product described and may be dispensed with. The fulling arrangement may be constructed to full the paper gradually from one side toward the other, although I prefer the central disposition of the first fulling-roller shown. \Vhile I prefer the rotary embossing-dru ms and dies shown, it will be understood that reciprocating dies may be employed on the longitudinally-fulled paper. The fulling-rollers 1 3 5 7 may be driven positively, if preferred. The intermediate roller N between the fulling mechanism and the embossing-dies is preferably a grooved roller, which does not injure the fulling.

I have found in practice that the machine operates satisfactorily with die-drums thirtysix inches in diameter at a speed of about three and one-half revolutions per minute. Any suitable strippers or guides may be employed for detaching the embossed sheet from the rollerR and delivering it down the plate V. The driving-shaft T is provided with tight and loose pulleys T In Fig. 4 the drums O and R are shown as provided with only one set of dies; but it will be understood that the drums are provided with suitable dies around the whole of their peripheries. The dies may be attached to the drums in sets adapted to produce the concavities to hold a dozen eggs, as shown, or in any other preferred way.
