Application filed November 15, 1915. Serial No. 61,605.

To all whom it may concern:

Be it known that 1, WILLI M GoonnLL, a citizen of the United States, residing at Millinoclret, in the county of Penobscot and State of Maine,have invented certain new and useful Improvements in Paper-Pulp-Lap- Folding Machines; and I do hereby 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.

The invention relates to a paper pulp lap folding machine.

The object of the present invention is to provide a simple, practical, and comparatively inexpensive paper pulp lap folding machine adapted to receive the sheets or laps of paper pulp as the same are discharged from a wet machine and equipped with a roller bed for. receiving the paper pulp lap and with means operating in timed sequence for successively folding the sheets of paper pulp or laps to the required size whereby hand folding as now practised in paper pulp mills may be entirely eliminated.

lVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Like numerals'of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, the paper pulp lap folding machine comprises in its construction a main frame 1 of substantially rectangular form and of any desired construction and provided with suitable bearings for a pair of spaced transversely disposed shafts 2 and inner and outer longitudinally disposed shafts 3 and 4 arranged in pairs as clearly illustrated in Fig. 1 of the accompanying drawings. The shafts 2, 3, and t are provided at intervals with arms 6 and 7 and they constitute folding devices for successively folding a sheet or lap of paper pulp. The folding devices are oscillated in timed sequence as hereinafter fully described. The shafts 2 are located in a horizontal plan slightly above the shaft 4 while the intermediate longitudinal shafts 3 are located slightly below the plan of the shafts 4. The arms 7 have angle bonds 8 to arrange their terminal portions 9 at right angles to the body portions of the rods as shown. The transverse shafts 2 are provided with central offset bends 10, which are adapted to lengthen the discharge hole 11 hereinafter described so that the folded lap may fall through without clogging at the ends and the intermediate longitudinal shafts 3 are located at the ends of the bends 10 which extend outwardlyas shown in Fig. 1 when the folding devices are in their normal or initial position. By this arrangement an open oblong space 1.1 is formed at the center of the folding machine. The sheets of paper pulp, which are approximately six feet square, when folded are discharged at the central open space. The shafts 2 are successively operated to fold a sheet of paper pulp transversely along the lines of the shafts .2 which are spaced approximately equidistant from each other and from theends of the machine.

The outer longitudinal shafts at are then operated simultaneously to fold the sheets longitudinally along the lines of the said shafts 4, after which the intermediate or inner longitudinal shafts 3 are simultaneously operated to fold the sheets centrally and cause the folded sheets to fall through the open space 11. The paper pulp lap folding machine is equipped with a roller bed composed of end and intermediate sections, the rollers 12 of the end sections being mounted in stationary bearing brackets 13 or other supporting means and the rollers ll of the intermediate section being mounted in bearings or suitable supports 15 andcarried by,

a vertically movable frame 16 operatedin timed sequence withrthe folding devices and adapted to be elevated to the plane ofgthe rollers of the end section when a sheet of paper pulp is deposited on the machine and lowered out of the way of the folding devices after the sheet has been arranged on The rollers project slightly the machine. above the plane of the arms of the folding devices and the rollers ll of the inter-me diate section of the roller bed are carried downwardly below the plane of the arms of the said folding devices and out of the way of the same so that the paper pulp may be folded in a flat condition without the foldtically movable frame is connected by links orrods 20 with crank elements 21 and 22 of an overhead transverse shaft 23. The lower ends of the links or rods 20 are connected with the horizontal pins 19 and the crank elements 21 and 22 of the crank shaft 23 while being shown in the form of simple cranks may be of any other form as will be readily understood. The crank element 22 is eccentrically connected with a stop-wheel 24 mounted on the inner end of a horizontal shaft 25 which has a sliding clutch-section 26 for engaging a clutch face 27 of a sprocketwheel 28 whereby when the clutch section is engaged withthe sprocket wheel, the shaft 25 will be rotated to actuate the vertically movable frame. The clutch section 26' may be slidably interlocked with the shaft in any desired manner audit is connected with'an upwardly extending arm 29 of anapproximately T-shaped lever 30 fulcrumedatits angle and having inwardly and outwardly extending horizontal arms 31 and-32. Thestop wheel 24- is providedat diametricallyopposite points withnotehes or recesses34 of substantially semi-circular: shape to enable the arm 31 of the lever 30 to engage \vith the said notches 3 1 and to be readily disengaged therefrom. The upwardly extending arm 29 is connected with a coiled spring-35 secured to the main frame or other suitable support and adapted to maintainthe clutch section 26 normally out of engagement with the sprocket wheel '28 and also hold the outer arm 32 of the T-shaped lever 30 against a flange or rim 36 of a cam gear wheel 37. The "cam" gearwheel 37 which is-preferably in the form of a sprocket wheelis provided-at the annular flange or rim 36"-With cams 38 and 39 arranged to suecessively engage the arm 32 ofthe T-shaped lever-30 to move the arm- 31out of engagement with the stop wheel and simultaneously carrythe sliding clutch seetion into engagement with'theiclu-tch face 27 of the gear wheel 28 whichpis preferably in the form of a sprocket wheel and Y which is continuously rotated by the meanshereinafter described.

This operation of the T-sha-ped-lever rotates the-shaft 25 and the stop wheel 2% which :maintains the lever 31 out ofengagement-with the notches 3 1 until the next notch is carried toa point above the arm 31. The shaft 25: is rotated during this time by the engagement of theclutch section or men1- bers. As soon as the stop wheel 2st has made one-half a revolution, the. other notch or recess 3 1 is carried to a position above the arm 31 which is moved into the notch 3% by'the spring 35ithereby withdrawing the clutch section 26 from engageinentwith the clutch face 27 of the sprocketwheel 28 and stopping the shaft 25. This half revolution of the wheel 2% and the shaft. 23 elevates themovable section of .the roller bed which remains in an elevated position. while the. pulp sheet is being transferred to the folding machine. hen this operation. has been. effected the wheel 37' through its cam 39 again operates the T- shapedlever-and permits another half revolution. ofthe shaft:23zwhich lowers the movable section of the roller bed from its elevated position to its position below the folding.devices.i In order to provide an easy movementofthe. frame 16, the movable section of the roller bed is counterbalanced by suitable weights lOconnected with one end of a cable 41 orother suitable flexible con nections which-is arrangedon an overhead pulley 4:2 and which is connected at its other end with the frame. 16 .at the center of the transverse member 18'.

Any other suitable means may of course be employed for counterbalancing the ver ticallv-movable sectionofthe roller bed and for. securingxan easy operation thereof in moving the. same to and from the horizontal plane of the stationary sections.

Each ofv the transversely disposed shafts 2 of the folding devices is equipped at one opposite direction to return them to their initial position. The stop wheel 47 is provided with a single notch or recess 48 and it is mounted on a shaft 49 having a slidable clutch section 50 adapted to engage a clutch face 51 of a sprocket wheel 52. The slidable section is connected with a T-shaped lever- 53 constructed similarly to that heretofore described and adapted to coijperate with the stop wheel 47 and with a cam wheel 54 having a single cam 55 on its annular flange or rim 56. The wheel 54 is in the form of a sprocket wheel similar to the cam wheel heretofore described and the cam of the cam wheel 54 of the two transverse shafts 2 is timed to secure a proper operation of the folding devices to successively fold the sheet of pulp from the ends of the machine over the central portion as before described. The T-shaped lever 53 is connected with a coiled spring 57 which operates similarly to that heretofore described in moving the T- shaped lever into the notch of the stop wheel and withdrawing the sliding clutch from the sprocket wheel 52. The outer longitudinal shafts 4 are provided at one end with pinions 58 which mesh with rack bars 59 operating in suitable guides and connected by rods 60 and 61 with crank elements 62 and 63 of a crank shaft 64 having an extension 65 on which is mounted a slidable clutch section 66 adapted to engage a clutch face 67 of a sprocket wheel 68. The slidable clutch section is operated by a T-shaped lever 69 controlled by a cam Wheel 70 and a stop wheel 71. The stop wheel 71 which is constructed similar to. the stop wheel 47 is mounted on the shaft 64 and the cam wheel 70 which is similar in construction to the cam wheel 54 is mounted on a shaft 72. The cam wheel 7 O is timed to secure a proper operation of the folding devices with which it is connected.

The inner or intermediate longitudinal shafts which effect the final folding and the discharge of the folded sheets of paper pulp are provided with intermeshing gears 74, 75 and arm 76 being connected with the gear 74 and with the shafts 3 on which such gear is mounted and adapted to be oscillated for simultaneously rotating the said shafts 3. The arm 76 is connected by jointed rods or members 77 and 7 S with a crank 79 of a shaft 80 carrying a stop wheel 81 of mechanism 82 having a sprocket wheel 83 and a cam sprocket wheel 84 and constructed similar to the mechanism for operating the vertically movable rack bars heretofore described. The cam of this mechanism is properly timed and when the mechanism is operated the arm 76 will be oscillated and the inner longitudinal rock shafts 3 will be simultaneously operated to effect the final fold of the paper pulp sheet and the dis charge of the latter through the space 11.

The actuating sprocket wheels of the several sets of mechanism and the cam sprocket wheels of the same are arranged in two horizontal rows as clearly illustrated in Fig. 3 of the drawings and are connected by sprocket chains 85 and 86 which are also arranged on driving sprocket wheels 87 and S8.

The driving sprocket wheels 87 and 88 are connected by sprocket gearing 89 properly proportioned to regulate the speed. of the cam wheels above mentioned and time their operation when suitably arranged on the sprocket chain 86.
