Application filed February 11, 1923.

This invention relates to winding machines and more particularly to machines for winding" sheet rooting material spirally to form rolls containing a definite length of the material;

an object of the invention is to provide a machine of the typifiedclass which embodies in addition to a winding mechanism for rolling; the n'iaterial; upon a mandrel. an electricallyoperable mechanisn' adapted to be previously adjusted with referent to the length of n'iaterial desired to be wound upon the mandreh so as to automatically arrest operation of said winding mechanism when the exact predetermined length of the material has been rolled up.

Another object of the invention is to provide in a winding machine; a mechanism for facilitating the preliminary unwinding of the material by power from a source of supply so that the starting; end of the material may be wound a few times around the man drel to permit the latter to secure a grip upon the material, after which the automatic Winding operation is continued through normal perfm-mance of the machine.

In addition to the foregoing, this invention comprehends improvements in the details of construction and arrangenrent of the correlated parts of what I now believe to be the preferred embodiment of my invention from among other possible forms and arrangements within the spirit of the invention and the scope of the appended claims.

In the accompanying drawings forming. a part of thisv specification:

Fig. I is a View in top plan of a winding and measuring machine constructed in accordance with my invention. I

Fig. 11 is a view of the machine in side elevation.

Fig. III is a view thereof in rear eleva tion.

IV is a detail view in broken longitudinal section of the winding mandrel; and

Fig. V is a transverse section on a larger scale taken on the line V'V of Fig. IV.

With reference to the drawings, 10, 11 and 12 indicate three pairs of supporting legs of structural iron, located in longitudinal spaced relation to support side rails 13, the latter in turn supporting a plate 14 forming the top of a table, which is inclined upwardly from the rear end, supported by Serial No. 535,944.

ends of the legs 10 and 11 terminate above the plane of the table top as shown, by pro viding suitable recesses in the plate 1 1-: to receive the legs 11 and by terminating the plate short of the; legs 10. The legs ll: and 12 areconnected by means of crossed braces 15, while the legs 10 and 11 are connected by means of a pair of horizontal braces 16. extending longitudinally of the 5 machine. Each brace 16 supports a bearing 17 between which a transverse shaft 18 is journalled. A pair of arms 19 are rigidly secured to the shaft 18,. one adjacent each end, and between said arms a foot pedal 20 is located and rigidlyiix'ed to said shaft. A pair of links 21 are mounted in contiguous relation to the legs 10, each said link being piv'otally connected at its lower end to its cor'responding arm 19 and guided in brackets 22, a pair of .which are mounted on each leg 10 in verti- A coiled spring 221 cally spaced relation. is embraced about each link 21 and interposed betwecn the brackets 22,- with the l-owerends of said springs bearing against the lower brackets 22 and their upper ends thrusting a 'amst pins 2% inserted in transits rear face and secured to each plate is a pair of spaced bearings 26 supporting: a

short section, of shaft 27between them in a horizontal plane. Loosely mountedon each v section of shaft 27 is one end of a lever28, of which a pair are provlded, a horizontal roller 29' being journalled at its ends between said levers and upon the same, for

movement in avertical direction toward and away fromthe table top 1 1. The upper end of each link 21 ispivoted to its correspond ing lever 28 at points intermediate the ends of the latter. It will be noted that the roller 29 is thus held in a normally elevated position by meansof the springs 23. Located beneath the roller 29 is a secondshaft supported roller 30, disposed parallel thereto and j'ournalledat its ends between bearings 31 secured to the side rails13, the surface of said roller rojecting slightly above the planeof the ta le top 1 1. This roller 30is located between the forward end of the table top 1 1' and a second section 1 1 of thelatter,

forming a continuation of said tabletop. Located in contiguous relation to the forward edge of the table top 14 is a mandrel designated generally at 32 and having the detailed construction shown in Figs. 1V and V, which consists of a shaft 33 enclosed by means of a spaced sleeve 34, the latter being provided with aplurality of longitudinal openings 35 extending substantially from end to end and through which movable fins 36 protrude, the latter having end extensions 37 to prevent complete protrusion of said fins. Mounted on the shaft 33, within the sleeve 34 are a plurality of cams 38, each rigidly held by means of a spline 39. Each cam 38 is formed with a plurality of radial lugs 40, corresponding in number to the number of fins 36 employed, and the periphery of the cam, between each pair of lugs 40 is curved substantially in a spiral manner to form cam surfaces 41, which engage against the inner surfaces of the fins 36. A coupling flange 42 is secured to one end of the shaft 33 for attachment to a complemental member 43 mounted on one end of a shaft section 44, suitably journalled. Rotation of the shaft section 33and parts carried thereby is effected by the shaft sec tion 44 under control of an electrically operable brake of conventional type, indicated generally at 45 the latter acting upon the shaft section 44 to permit or arrest motion thereof. A second shaft section 46 is journalled in alignment with the shaft section 44 and is adapted to be coupled to the section 44 and uncoupled therefrom by means of a conventional form of electrically operable coupling device or clutch 47. A pair of pulley wheels 48 and 49 are fixed upon the shaft section 46, one adapted to be belt driven from a source of power, and the other arranged to drive a pulley 50 by means of a crossed belt 51. The pulley 50 is mounted on a shaft 52 constituting an extension of the shaft which supports the roller 30.

Referring now to the measuring device, the upper ends of the legs 11 carry between them a transverse bar 53, preferably square in cross section but having rounded terminals which rest in the slots 54, of which a vertically spaced series is formed ineach leg extension 11.

A frame plate 55 is secured along one edge to the bar 53 and extending rearWar-dly supports a casing 56 containing a current controlling switch of conventional type having feeders 57 which lead to the brake and clutch elements, 45 and 47, respectively. A plurality of bearing brackets 58 depend from the plate 55 and support a transverse shaft 59, upon each end of which a wheel 60 is fixed, said Wheels resting upon a short transverse roller 60 suitably journall-ed for free rotation and projecting through an opening in the table top. A bevel gear 61 is fixed to the shaft 59 a roll.

and meshes with a bevel gear 62 mounted on a shaft 63 which is intended to drive the mechanism of the switch contained within the casing 56. An arm 64, extending forwardly and fixed to the bar 53 and the plate 55, carries a counterweight 65 which may be secured in any adjusted position by means of a bolt 66 that enters the weight and engages the said arm. The table top 14 is provided adjacent each side edge with several series of transversely spaced openings 66 and resting upon the table top are .a plurality of angle bars 67, one adjacent each side edge. These angle bars constitute guides and are designed to be variously spaced and held in fixed relative positions by means of .pins 68 which enter the bars and aligned openings 66 therebeneath.

The machine just described is primarily designed for handling roofing material which consists of a base, such as paper, felt or similar substance, treated or impregnated with bituminous and other materials which render said base material waterproof, flexible and rather heavy. During the manufacture of this material the resultant product is usually wound spirally, forming a large roll. The material is subsequently unrolled and re-rolled into small rolls containing short lengths, convenient for shipsaid guides and then fed by hand between the measuring wheels 60 .and the roller 6O andfinally located over the roller 30. It will be observed that the roller 30 is designed to rotate continuously under the influence of the continuously rotating shaft section 46. The foot pedal 20 is now depressed bringing down the roller 29 into engagement with the end of the material causing the material to be fed toward the mandrel 32. The material is then brought beneath the mandrel 32 and wrapped or rolled a few times around the same. This may be facilitated by rotating the sleeve .34 relative to the shaft 33 in a direction reverse to the normal winding direction of said shaft. The fins 36 will ride to the inner ends of the cam surfaces 41 bringing the outer surfaces of said fins flush with the surface of the sleeve 34. A switch button 69 mounted on the casing 56 or other convenient place is now actuated to close a circuit for the purpose of energizing the clutch 47 so to lock together the shaftsection 44 and 46, thus transmitting rotative movement to the mandrel 32 and causing the material to be wound thereon to form Under the rotative stress of the sleeve 34 the 36 will be moved outwardly engaging the inner layer of the material and efiecting a tight grip. The frictional engager'nent of the material passing beneath the measuring wheels will cause rotation of the latter, which rotation is transmitted through the gears 61 and 62 to the shaft 63,

operating the switch mechanism within the casing The switch mechanism is ot a nature to break the current to the clutch 4L7 after the wheels 60 have made a number of revolutions corresponding to a peripheral travel of a predetermined extent, thus disconnecting the shaft sections as and 46 and permitting the mandrel 32 to come to rest.

The material is then severed transversely which may be either of a type to arrest motion through magnetic stress induced when the mechanism is energized by the passage of an electric current, or of the type in which the braking power is supplied by springs or the like, held normally under tension and released by the making or breaking of a current.

Since these elements are well known a detailed description of their construction is not necessary, it being su'flicient to point out what functions are expected of them as parts of the form of winding and measuring described above. The weight 65 may be shifted to partly balance the weight of the switch mechanism. so as to relieve the mate rial passing therebeneath of undue pressure.

In connect-ion with the measuring device 56, it is to be-noted, the same is purposely actuated by the material being wound in order to insure greater accuracy of measurement than is possible with ordinary measuring rolls. Furthermore, the measuring device 56 is so arranged that when a defective piece of material makes its appearance, and it is desired to exclude such defective portion from the predetermined length of good material, the operator simply rocks the device 56 from contact with the material by pressing downwardly on the freeend of the arm 6%, thereby elevating said device and preventing measurement of the defective material. Obviously, suitable means are provided -for stopping the winding operation, so that the above mentioned defective material may be cut oil and removed, where'- upon winding 1s resumed, with the device 56 returned to normal'op'erative position, without any inaccuracy occurringin mleasurement of the material, whether the roll comprises one sheet or a plurality of sheets.

From the foregoing it will be seenthatl have devised a machine that is extremely simple in construction and well adapted to handle a material having the characteristics of bitumenized material. It will however be obvious that the construction shown may be used for winding and measuring many other kinds oi material tocqnal advantage.
