SPECIFICATION forming part of Letters Patent No. 427,705, dated May 13, 1890.

Application filed .Tune l, 1887. Renewed September 9, 1889. Serial No. 323,349. (No model.)

To @ZZ whom it may concern.-

Be it known that I, EDWIN D. HCCRACKEN, of Alpine, in the county of Bergen and State of New Jersey, have invented a new and useful Improvementin lliachinestor Making Paper Tubes, of which the following is a specification.

My invent-ion relates to a machine which in some respects resembles an ordinary lathe, in

1o that it is provided with head and tail spin dles for supporting and driving a mandrel, and by which thin paper from a reel and in a strip of considerable width may be wound spirally and continuously from end to end of the mandrel to form a tube of proper 'thickness, paste or other adhesive substance being employed to produce adhesion between the overlapping and superposed spiral convolutious. p

2o I employ in connection with head and tail spindles for supporting a rotating mandrel, a rotary feed-shaft and a main sliding carriage operated thereby and caused to travel along shears or ways similar to those of a lathe.

Upon the main sliding carriage I support a rotary carriage or turn-table and a paper reel or drum, which is mounted to rotate in a substantiall y vertical plane on the rotary carriage or turn-table, and has its diametrical 3o and axial center substantiallyin line with the center of the rotary carriage or turn-table. lVhen the rcel is thus arranged relatively to the rotary carriage, the carriage and reel. may be readily adjusted to `give the paper adirection oblique to the mandrel, either in one direction or the other, from a central line, and thus bind it spirally upon the mandrel from either end alternately toward the other end. Although the rotary carriage or turn-table 4o may be considered as supported upon the main sliding carriage, it is directly mounted upon a carriage which is 'fitted to slide onthe main carriage and transversely to its line of movement and to the length of the mandrel,

and the rotary carriage or turn-table may be formed with a circle ot worin-teeth, with which engages a tangential. worm or screw for shitting it.

I also employ a paste-applying roll or rolls,

5o which is orare pressed by springs against the paper tube on the mandrel during'its formation, and preferably the paste-box, in which the rolls are journaled, is guided in a saddle iitted upon the main sliding carriage and is supported in said saddle by springs. I here use the term paste-box and paste-applying roll in a generic sense, thereby meaning to include a box and roll for applying any ad hesive substance.

I also employ a pressure-roll, which bears 6o upon the top of the tube during its formation and produces the firm union of thespiral convolutionsby means ot the adhesive substance and presses and consolidates the paper. This roll is preferably journaled in a yoke, which is adapted to turn and also to rise in a horizontal arm, which is fulcrumed upon a post at the back of the machine and is capable of swinging horizontally, so as to bri ng thepressure-roll to any desired position lengthwise ot' 7o the mandrel, and I also employ parallel con nections on opposite sides of thisarm and extending to opposite ends of the roll, so that during the swinging movement of the arm the roll will always be maintained parallel with the mandrel.

I also employ a post having a disk-cutter mounted upon it and provide a socket on each side of the upper sliding carriage for receiving the post and to enable it to be used for 8o cutting oit first one end and th-cn the other of the paper tube.

The head and tail spindles maybe provided with suitable centers for supporting the mandrel, and the center upon the head-spindle may have a longitudinal groove, with which engages a rib secured to one side ot thehollow mandrel, and through which rib and groove the mandrel is driven positively by the headspindle. 9o

For imparting motion to the'main sliding carriage, I prefer to employ an ordinary feedshaft, which is geared to the head-spindle, S0 as to rotate at any suitable speed., and this feed-shaft has mounted upon it, within the sliding carriage, reverse bevel-wheels having clutch members formed integral therewith, and the feed-shaft also has upon it movable clutch members having groove and spline or feather connections with the shaft. Both the roo reve rse bevel-wheels are in constant gear with a third wheel, which in turn andthrough suitable gearing transmits motion in one direction or the other to a wheel which gears with a rack on the under side of the bed, and by the engagement of this wheel with the rack the sliding carriage is moved in one direction or the other at a very quick speed as compared to the feed of a lathe.

The invention consists in novel combinations of parts, which are hereinabove brieliy referred to and hereinafter described, and pointed out in the'claims.

ln the accompanying drawings, Figure l is a side elevation, and Fig. 2 a plan, of a machine embodying my invention, a portion of the length of the machine between the head and tail sockets being broken away to reduce the size of the drawing. Fig. 3 is an end View of the machine, including the gearing whereby the feed-shaft is operated. Fig. 4 is a transverse section of the machine, upon a plane extending through the main sliding carriage. Fig, 5 is an elevation and partial section of the pressurcroll and the paste-roll and paste-box,incltidiiig a saddle supporting the pasteebox and applied to the main sliding carriage, and a sectional View of a portion of the gearing in the main sliding carriage upon about the plane indicated by the dotted line fn,Fig. 4t. Fig. 6 is a horizontal section upon about the plane indicated by the dotted liuey/ y, Fig. 4, of the main carriage and the appurtenances or gearing connected therewith. Fig. 7 is a vertical section, and Fig. S a horizontal section, showinga portion of the rotary carriage or turntable and the transverselysliding carriage which supports it. Fig. O is a detail'view illustrating the center, which is upon the head-spindle, and the means employed for imparting motion, therefrom to the mandrel; and Fig. 10 is an elevation of a cutter operating upon the paper tube for cutting off its end, and which is supported from the transversely-sliding carriage on which is the turn-table or rotary carriage.

Similar letters of reference designate corresponding parts in all the figures.

A designates the bed, and Z) the tracks, ways, or shears, such as are ordinarily provided upon a lathe. At one end of the bed is mounted a head-stock B, in which is journaled a head-spindle orlivespindle C, having a cone-pulley (12, and on the opposite end of the bed is fixed a tail-stock B', in which is journaled the usual tail-spindle C.

D designates a mandrel, which usually consists of a tube of metal fitted upon the centers c c and the live center c, or the center upon the head-spindle C may have a longitudinal groove c2, which receives a rib or tongue cseeured to one side of the mandrel. Through this groove and rib or tongue the live-spindle C transmits rotary motion to the mandrel I).

At the front of the machine extends a feedshaft E, which is journaled in suitable 4bearings e, and through a suitable train of gears the live-spindle C transmits motion to this feed-shaft. In this example of the invention the train of gears comprises a pinion or wheel c upon the live-spindle C and wheel e? upon the eedshaft, and the intermediate wheel e3, which engages with both the. wheels e e2 and is journaled upon a stud secured in the lever E', fulcrumed upon the feedshaft E. Thelever is provided with a slot et, in which the stud c5, on which the wheel c3 is journaled, is adjustable, and is likewise provided with an arc-shaped slot e, through which passes a clamping-bolt e7, and by which the lever E may be adjusted and held at any desired angle to the horizontal. The two slots e6 e4 provide for introducing a larger or smaller wheel in place of the wheel e3, and therefore provide for imparting a slower or quicker mo tion to the feed-shaft E.

The machine comprises a main sliding carriage F, which, as best shown in Fig. et, is snpported to slide freely upon't-he tracks or ways b, and which is moved to and fro along' the mandrel D by mechanism set in motion by the feed-shaft E.

The mechanism for operating the carriage is best shown in Fig. 6.

On the shaft E are fitted reverse bevelgears ff', both of which engage with the bevel-wheel f2, and which also comprise clutch members ffl. The bevel-gearsff are held in proper position to engage with the wheel f2 by studs f5, secured in the carriage F and engaging suitable grooves f in the gears and clutch members. On opposite sides of the gears and clutch members f f are .fitted sliding clutch members f7 fs, which havea groove and spline or feather engagement with the shaft E, so as to receive positive rotary motion therefrom and so as to permit their sliding along the shaft.. The sliding clutch members f7 f8 may be operated by cams or eccentrics, which consist of pins f, set eccentrically in disks, which are upon short shafts or studs flo, as best shown in Fig. 6, and these short shafts or studs fw are provided at the front of the carriage with handles f 11.

As shown in Fig. G, the sliding clutch member f7 is adjusted into engagement with a companion clutch memberfg, which forms a part of the gear f, and thereby the gear f is rotated and transmits its motion to the gear f2, and at the same time the movable clutch member f8 is slid out of engagement with the clutch member f4, and the wheel f and clutch member f4 are free to rotate idly by their engagement with the wheel f2.

Upon the under side of the bed is a longitudinal rack h, and 7L designates a spur wheel or pinion, which is mounted upon a stud in the carriage and engages with this rack. Gearing with the wheel or pinion h is a second wheel or pinion h2, which is upon the short shaft h3, supported in suitable bearings in the carriage, and at the outer end of this shaft is a wheel 7a4, which is geared with the pinion 71.5 on the same short shaft h6 to which the bevel-wheel f2 is attached.

Frein the above description it will be un- IOO IIO

derstood that the Wheel f2 will be rotated in one direction or the other, according to whichever of the wheels f f transmits motion to it, inasmuch as they engage with its opposite sides, and by the rotation of the wheelj"2 the train of gears 7i5 7L'l 7L2 7L Will be rotated, and by the engagement of the wheel 7i with the rack 7L the carriage will be moved at the desired speed in one direction or the other along the tracks or Ways b.

I have also represented on the carriage F a short shaft or spindle 707, provided on the front of the carriage with a handle hs and provided on the inner end With a wheel 7L, which engages with the rack 71, and by this handle 7L8 and wheel 7L" the carriage may be moved rapidly along the tracks or Ways when both the movable clutch members f7 f3 are adjusted to the position of the clutch member 2o f7 in' Fig. G.

H designates a carriage, which is mounted directly upon the main carriage F, and by means of the screw II', provided with the hand-wheel at the front of the machine, may be slid or shifted upon the carriage F in a direction transverse to the length of the .mandrel D, along a gibbed Way or tongue 7N), upon the main carriage. The transverse adjustment of the carriage H provides for vary ing the distance from the paper-reel I to the mandrel D, as may be desired when spirally winding paper upon mandrels I) considerably larger than that here shown. The rotary adjustment of the carriage Il2 and the sliding adjustment of the carriage H also combine to attord provision for laying the paper spirally upon the mandrel D at exactly the desired angle.

H2 designates a rotary carriage or turn-table, which is mounted in the transverse carriage II, and which is constructed with a circle of worm-teeth 71,11, and 7N designates a tangential shaft or key, on which is a Worm 7tlg, engaging with this circle of gear-teeth. The projection on the carriage H2, on which are formed the Worm-teeth 7L, is received in a cavity in the transverse carriage Il', and by turning the worm-shaft 7L12 the carriage O1' turn-table Il2 may be rotated to the extent desired. The carriage H2, although supported directly and rotatable on the transverse car riage H, may be regarded as supported from the main sliding carriage F.

On the rotary carriage or turn-table II is a standard t', supporting a suitable shaft I, to which is fixed a paper reel or drum I, and the shaft I and standard t' are so arranged that the diametrical and axial center of the drum I is directly in line with the center of the turn-table H2, and as the turn-table is rotated the angle at which the strip of paper is delivered from the reel I upon the mandrel is varied, and the strip of paper may be delivered at an angle on either side of a plane directly transverse to the mandrel by shifting the rotary carriage or turntable H2 tothe desired position.

On the shaft I, I have also represented a brake Wheel or disk 97,011 which acts a springactuated brake-shoe i2, movable vertically by the action of the spring in the standard ff, so as to retard the rotation of the reel I and offer a su flicient resistance to the unwinding ot' the paper to produce the smooth-laying under tension of the paper upon the mandrel D.

To secure the firm adhesion of the spiral convolutions of paper, I employ a paste-box J, which contains paste or other adhesive material, and in which are journaled a paste roller or rollers J. In this example of the invention, two rollers bearing upon the paper tube Which is being formed and arranged on opposite sides of the center of the tube are` employed7 and I may employ springs for maintaining the roller or rollers, pressed against the paper tube, which is Wound on the mandrel D. In the present example of the invention a saddle J2 is fitted to the dovetailed proj ection 7am at the top of the carriage F, and contains sockets j, which receive down Wardly projecting stems j ou the pastetrough J, and these sockets contain springs j?, which bear upon the stems and thereby hold the roller or rollers J against the paper tube by pressure transmitted through the paste-box J.

To consolidate the paper and produce the firm union of its several convolutions by means of the adhesive substance, I employ a pressure-roller J 3, which is in this example of my invention journaled in the yoke J, suspended from a horizontal arm J5, Vwhich is mounted upon a post J6 at the back of the machine. As represented, the post is secured in place upon the sliding carriage F by bolts jig, which pass through slots j and provide for the adjustment of the post toward and from the mandrel D. maintained in vertical position and prevented from falling on the post J is free to turn thereon and is supported vertically by a collar 17"", and the roller-yoke ,Il has a stem je, which is adapted to turn and rise in the end of the arm Consequently it Will be seen that the pressu1e-roller J 3 bears upon the paper tube with a force due to its Weight and to the Weight of its yoke J 1, and is free to rise slightly and still maintain a uniform pressure as the paper-tube increases in size due to the winding of the strip upon it. I have here represented upon the post J6 a cross-piecef, from opposite ends of which parallel connections jS extend to and engage with the roller J3 or with the opposite ends of the yoke J4, and which serve to maintain the roller J3 in position parallel with and above the mandrel D, notwithstanding the angle to which the arm J5 is adjusted.

After the tube has been formed upon the mandrel it is desirable to cut off its ends truly, and to do this I employa rotary or disk knife 71:, which is mounted in a standard 7c', and I provide the transversely-sliding carriage H TOO The arm J5, although it is IIO with sockets 7a2 at opposite sides, as best shown in Fig. 2, into either of which the post 7o may be inserted in order that provision may be afforded for cutting off one end of the tube and then the other. Aftero the tube is thus completed and cutoff at the ends the mandrel D may be removed from it by any desired v method.
