MACHINE FOR MAKING PAPER PAILS.

SPECIFICATION forming part of Letters Patent No. 341,163, dated May 4, 1886.

Application filed February 8,1886. Serial No.191,217. (No model.)

To all whom it 11mg concern:

Be it known that I, FRANKLIN D. PEOK, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Machines for Making Paper Pails, of which the following is a specification, reference being had to the accompanying drawin s.

%\Iy invention relates to improvements in machines for making paper pails; and it consists of the peculiar and novel construction and combination of parts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

The objects of my invention are to provide improved means for conveying the pulp from a receptacle to the proper forms on which the pails are first made, and which at the same time shall permit of the proper discharge of surplus water or other fluid that is forced from the pulp; to provide improved means for conveying the pulp from the receptacle to a traveling carrier; to provide forms of the proper configuration that are readily and quickly removable, to be replaced by other forms of similar construction; to provide means for exerting the proper requisite pressure on the forms to compress the pulp very firmly and compactly, and at the same time force any surplus water or other fiuid from the pulp; to

provide means that shall be conveniently operated to release the pressure-rolls from bearing and pressing on the forms when the latter are to be removed; to provide means for positively rotating the pressure-rolls; to provide troughsfor conveying and discharging the wa- V ter or other fluid pressed from the pulp by the pressure-rollers, and to provide means that are simple and strong in construction and thor- --oughly effective and reliable in operation.

I attain the above-named objects by the mechanisms which are illustrated in the accompa nying drawings, in which Figure l is a side elevation of a machine for making paper pails,constructed in accordance with my invention. Fig. 2 is a horizontal sectional view on the line :0 w of Fig. 1. Fig. 3 is a transverse vertical sectional view on the line 3 y of Fig. 2. Fig. 4 is alongitudinal sectional view on the line zz of Fig. 2. Fig. 5 is a detail view of one of the removable forms with its standard and frame, and Fig. 6 is a similar view of the pressure-roller and the means for elevating and depressing the same.

Referring to the drawings, in which like letters of reference indicate corresponding parts in the several figures, A designates supporting uprights or columns that are suitably disposed and arranged to support a cover or roof, a, to protect my improved machine and provide for suspending or holding hangers of the pressurerollers, as will more fully appear presently.

B designates a receptacle or vessel, of any preferred form and dimensions, to receive the pulp from which the pails are to be formed, the pulp being made before it is deposited in the receptacle.

0 designates a roller that is arranged to revolve in the pulp-receptacle B and convey the pulp therefrom to a traveling carrier, D, that rotates in a horizontal plane around a rotatable center and supplies the forms E with pulp from the receptacle B. This conveying-roller 7 5 G is rigidly mounted on a shaft, 0, that is journaled in proper bearings on the receptacle B. One end of this shaft 0 is extended beyond the receptacle B, and receives a pulley, crank, or other suitable mechanical device for rotating the shaft from a motor or other source of power, and the other end of this shaft, which, for convenience, I will term the driving-shaft, carries a spur gear-wheel, c, that meshes with a rack, d, on the traveling carrier D.

The traveling carrier D is made circular in form,and it comprises an inner and outer ring, d d to which are secured the edges of an intermediate canvas or other fabric section, (P, that is stretched and held taut on the rings or 91: open frame. The inner ring,d',is provided on its under and upper surface with teeth or cogs, that constitute the racks d,and said inner ring of the carrier has radial arms (1*, which meet at a common center and are rigidly secured 95 or keyed upon a vertically-disposed shaft, (2 which isjournaled at its ends in bearings D D". The bearing D is rigidly held in place on the floor, ground, 810., and the bearing D is formed in or rigidly affixed toa cross-beam, 10o D ,that is supported at its ends on columns or uprights D. In lieu of supporting the shaft d in the beam D, the latter and its columns may be dispensed with and the upper end of the shaft (1 journaled in a proper bearing properly affixed to the cover or roof a. The traveling carrier D is thus composed of an open-geared frame and fabric section, and the carrier is disposed in an approximately horizontal position, so that one edge thereof shall be lower than the other edge that lies diametrically opposite therefrom, or the carrier may be said to occupy a horizontally-inclined position and to rotate ina horizontal plane.

The conveying-roller G bears against the lower under face of the canvas or fabric section of the open frame of the traveling carrier, and the pulp from said conveying-roller adheres to the canvas or fabric of the traveling carrier until it comes in contact with the periphery of the forms E, to which it adheres to form the body of a pail. These forms E are shaped to correspond to the curvature or inclination of the vessel or pail body which is to be formed thereon,and in thepresent instance I have shown said forms E in the shape of a frustum of a cone with their smaller diameters on the inner end or nearest the center of the rotatable traveling carrier D. The incli nation or angle of the carrier D corresponds to the inclination of the forms E, so that the peripheries of the latter can bear equally at all points against the fabric section of the carrier to distribute the pulp evenly and uniformly on the forms, and the conveying-roller Ois also made frustumshaped, to uniformly apply the pulp to the fabric of the traveling carrier D.

In the drawings I have shown two forms E; but it will be understood that three or more may be employed if it is deemed desirable.

Where onlytwo forms are provided for the machine they are used one at a timethat is to say, when the form of standard No. l is in use or receiving pulp from the carrier, the form of standard No. 2 is removed or out of contact with the carrier, and vice Versa, as it will be readily seen that if both are allowed to remain in use the form of standard No. 1 will take up all ornearly all of the pulp from the carrier, and the form of standard No. 2 will receive a very meager or no sup ply at all. Ihave also provided and arranged means whereby both forms can be allowed to remain in their standards and to bring or adapt the carrier to supply either one of the forms with pulp, which devices and their operation will be presently described.

The rollers or forms E and their standards are disposed beneath the elevated or higher end of the horizontallyrotatable carrier, and the carrier is normally elevated above and out of contact with the peripheries of the forms. Each form is provided at its ends or heads with pins or studs 6, which are loosely mounted in proper bearings, f, which are secured to or cast with a frame, F, that is arranged to slide vertically in grooves or recesses g of standards G, which are connected at their lower ends. These vertically-sliding frames F and their fixed standards G are of any suitable form or construction, and the forms E are loosely mounted in the bearings of the frame, to adapt them to be readily detached or removed and interchanged, after they have been supplied with pulp, with forms of similar construction that are to be filled with pulp. The sliding frames are adapted to be elevated to any suitaable height to bring the forms into proper juxtaposition to and contact with the fabric section of the carrier D, and when the frame and form have been properly elevated and adjusted they are rigidly held in place by means of a catch, h, that enters a notch or socket in the frame, or by any other suitable or preferable means. The frustnm-shaped forms are rotated by frictional contact with the periphcry of a rotating pressure-roller that bears on the canvas section of the carrier, and it will be readily seen that when the carrier is'in motion it will apply the pulp to the form,and at the same time the form will be rotated by the rotatory pressure-roller, which evenly and uniformly applies the pulp to all parts of the form throughout its entire periphery. After the form has been covered or coated with the pulp to the required thickness it islowered and re moved from the frame, without stopping or otherwise interfering with the motion of the machine, and its place supplied by another form of similar construction.

Each form is acted upon by a pressure-roller, I, that is suspended above the fabric section of the traveling carrier and serves to compress the pulp very firmly and compactly on the form. The pressure rollers are made frustum-shaped to correspond with the angle of the form and the inclined rotatable carrier D, and the conveyingroller 0 also has a pressure roller, I, bearing thereon with sufficient force to cause the pulp from the conveying-roller to adhere to the carrier D; but the force which the roller I exerts on therollcr O isregulated so that it is considerably less than the pressure of the rollers I on the forms E.

The rollers I and I are each provided at their ends with studs or pins 2', which are free to move in slotsj, that are formed in vertically-disposed arms j of hangers J, which are suspended from the cover or roof a. The hangers may be of any suitable construction, and the lower ends of the slotsj may be left open and carry a removable pin. j, whereby the pressurerollers can be readily removed.

I will now proceed to describe my preferred form of device for regulating the pressure on the pulp and form.

A yoke, K, is connected loosely to the studs 03 of each of the rollers, to permit them to turn freely, and to a lug, 7c, of this yokeis pivoted a lever, L, which extends through and is pivotally supported within a slotted portion,

Z, of one of the armsj of the hanger J. Asimilar lever, M, is pivoted at or near its middle to a suspended rod, m, and one end of this lever is pivoted to the free end of the lever L, and to the opposite end of the lever M is pivoted a link, N, which connects with an operating han- IIO d1e-lever, O, which is pivoted at one end to a standard, 0, and has a tooth, 0, adapted to engage and be retained by one of aseries of teeth on a rack'bar or standard, 0. This handle-lever O is normally held down by a coiled spring, 0, or by a weight, so that the pressure of the pressureroller can be varied. It will be seen that when the free end of the spring-actuated pivoted handlelever is elevated the connected ends of the pivoted levers L M will be depressed and the inner end of the lever L will be elevated, to raise the bracket or yoke K and the presslire-roller, and when the free end of the handle-lever is depressed the pressure-roller will be lowered, to bear against the traveling carrier, the degree of elevation or depression depending upon the amount of movement of the handle-lever, as will be readily understood.

Each of the pressure-rollers I is positively rotated by motion transmitted thereto from rotatable traveling carrier D, through a pinion. P, rigidly secured to the extended inner stud of the pressure-rollers I, and meshing with the teeth or cogs of the rack-bar on the upper surface of the rotatable carrier.

Q designates troughs,that are arranged parallel with the pressurerollers I and trans versely across the traveling carrier, and this trough is suspended abovethe traveling carrier by means of rods or cords q. The troughs are to receive and discharge the water or other fluid that is forced from the pulp through the porous fabric or canvas of the traveling carrier by the pressure-rollers and to convey the same away from the forms, to prevent the pulp thereon from becomingtoo wet, and thus they can be more quickly dried.

When the forms E are elevated to bring them into operation, they bear against and elevate a portion of the flexible fabric of the traveling carrier, so that the fabric is inclined for a portion of its length, and as the pressurev'roller forces the surplus water from the carrier and the form.

pulp the water will permeate through the fabric and descend the inclined portion of the fabric, and flow into the discharge trough or spout, by which it is conveyed from the The inclined discharge spout is suspended above the t-ravefing carrier, and its open side is arranged to bear on the fabric of the carrier, whereby, when the lat ter is elevated by the form to produce the incline, the water from the pulp will readily enter the trough.

Each of the troughs is provided with an inclosing-wall around its several edges, except at the part or side that lies alongside of the pressure-roller, which is left open, so that the water, 830., can pass into and through the trough, and one end of the trough or dischargespout is contracted and extended beyond the edges of the carrier, to convey the water therefrom and discharge it into proper receptacles, the troughs being arranged in an inclined position, to more efi'ectually discharge the water.

Q designates a similar discharge-spout for the pressure-roller I, that is suspended and disposed in an inclined position, one end thereof being left open to receive the water that is forced through the fabric section of the carrier by the rollers O and I.

The operation of my invention is as follows: 'I he pulp, which has already been prepared, is poured or otherwise discharged into the receptacle or hopper B and the pressure-roller I adjusted to bear on the conveying roller 0 to the proper degree, the force thereof being regulated, so as to only press a portion of theewater from the pulp and to cause the pulp to adhere to the carrier. One of the forms E is adjusted or elevated to bear against the fabric section of the carrier, and the pressure-roller I lowered to bear on said canvas section of the carrier above the latter and the form, after which power 011110 tion is communicated to the drivingshaft c. The roller 0 is thus revolved to convey pulp from the reservoir or reoeptacleB to the traveling carrier, which conveys it to the form E, where it is discharged onto the latter. Simultaneously with the rotation of the conveying-roller O the horizontally-rotatable traveling carrier D is revolved, and the motion thereof is transmitted to the form E and pressureroller I by frictional contact between the form and pressure-roller and the gearing dB. The positivelyrotatcd pressure-roller serves to rotate the form by hearing thereon, and to press the surplus water from the pulp through the canvas, and it then, passes into the dischargespout or trough Q, and at the same time the pressure-roller compresses the pulp compactly and firmly on the form E. \Vhen the form E is coated with pulp toasufficient thickness, the pressure-roller I that bears thereon is elevated by elevating the handle-lever O and the sliding frame F lowered, after which the form with the pail thereon is removed and its place supplied with another form of similar construction. Simultaneously with the elevation of one pressure-roller and the de pression of the form that coacts therewith another pressure roller and form are adjusted for use, and this operation is continued without requiring the stopping of the machine.

It will be observed from the foregoing description, taken in connection with the drawings, that I provide a machine which compresses the pulp very firmly and compactly on the form of required shape, and that the v latter is readily interchangeable withoutstopping the motion of the machine. I provide for the proper supply of the pulp and the discharge of surplus water, and also regulate the pressure on the forms, so that a greater or less quantity of pulp can accumulate thereon, while at the same time the pulp is evenly and uniformly applied throughout all points on the periphery of the form.

I do not desire to limit myself to the details of construction and form and proportion of parts herein shown and described as an embodiment of my invention, as I am aware that many changes may be made without departing from the principle thereof.

I am aware that it is not broadly new to employ a horizontal rotatable carrier having a sieve, a forming-roller bearing on the upper surface of the carrier and mounted in a vertically-movable frame fitted in proper standards,

and a pressure-roller on the under side of the carrier beneath the forming-roller and having a rack which meshes with a pinion on a handshaft to adjust the pressure-roller vertically.

I am also aware that it is not new to employ a centrally-supported horizontal felt-carrier which rotates about its'axis and is inclined,a trough in which works a conveying-roller to transfer thepulp to the felt-carrier, apressureroller to the conveying-roller, a supplemental frame pivoted centrally to the main frame and carrying a forming roller at each end, the frame being rotatable on its shaft to bring either roller in contact with the felt-carrier, a pressure-roller to the forming-roller, and a shaft having belts to rotate the pressure-rollers.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, isi 1.
