TUBE-WINDING MACHINE.

Specication of Letters Patent. Patented Sept, 26,', `191,1, Application led October 3, 1910. Serial No. 584,969.

To all whom 'it may .v

Be it known that I, CHARLES F. WELSH,

. a citizeniofthe United States, residing at Y and ldeclare the followin to be a'full, clear,-

Detroit', county of Wayne, State 'of Michian, have invented a certain new andv useful mprovement in Tube-Winding Machines,

and exact description o the same,I suchas *will enable others skilled in the art to which itpertains to make and use the same, reference being had to the accompanyin draw- '.ings, whichA form a part of/this speci cation. This inventionrelates to tube-wlndl'ng machines.

It has for its object an improved machine f -for winding .what-are known as spirally wound tubes; in the construction of devices of this class a ribbon of 'paper is wound spirally around a :mandrel by revolving the mandrel on its axis and drawing the ribbon of' paper from its storageroll as it is used in the construction of the tube; the tube underjcnstruction is pushed oil' from the free end. of theman'drel and is'cutinto lengths to produce the commercial tube or box. The winding ribbon is held lirmly against the mandrel or against an under-'lying part of -the ribbon by beltsy that cross the mandrel obliquely theretoand thenressure of the belt serve sto press the paste or glued surfaces of the ribbon into close contact.

The main object Vof this invention relates 'tomeans for adjusting these obliquely lying beltswhile maintaining their dr1v1ng mecha- -vation of the 'mam drivi nism in proper relationtherewith.

In the drawing :-Figure 1, is a plan view of the machine. F-i 2, is a cross section at the line 2-2of Flg. 1. Fig. 3, is a hori i the pressure belts.

On a frame A is mounted a master wheel lion a shaft 2L On the shaft is a miter wheel 2HL which ears with a miter wheel -3 on the vertical s aft 3 and drives the same, thereby transmitting motion tomiter Wheels 4 and 5 and driving horizontal shaft 6 which .extends to the side of the frame 'and has mounted upon it amiter'wheel 8iarranged to slide longitudinally of the shaft 6 ,and

meshes with miter wheel 9 on shaft 10. The

shaft 10 is carried in, bearings which4 will be hereinafter described land is capable of ,l

lateral movement with respect yto the frame A. The two wheels 8 and 9 are yoked by a yoke 11 that holds them at all times in mesh slidingihe :wheel son its `sima et@ correspond with theflateral movement of the shaft 10, The shaft lis'carried at .the end of Vtwoparallel members oscillating 12 and-12, these two members and the various attachments to them are 'similar` in all respects, and only' one 'of them will be de scribed, with the understanding that thesecond one, is exactly similar to the one described,y and that the indicating numerals .on the second member 128L are similartothe numerals on the Vmember described. with the exception that each one has an alphabetical character connected with it to distinguish it from the corresponding number .on the member described.V The member 12 is pivotally supported on the crosspart B ofthe frame and held thereto by a bolt 14 and nut 15. The bolt 14 terminates at its head end with a cap which engages over a raised ring 16 on the member 12, vand the entire member 12 oscillates the member B, Vand is actuated in its oscillating movement by parallel rod 17 that couples 12 and 12, and isy provided with a rack 19that enga es with driving gear 20 on a shaft actuated y hand winch 18. The shaft is journaled inthe main frame A. The oscillating cross mem ber 12 carries at one end. a stud 21 which carries a miter wheel 22.` The stud is coupled tol the shaft 10 lby `yoke 24 pivotally.y

connected to the stud and slidingly connected to the shaft. Mounted slidingly on the shaft is a initer wheel 25 arranged to be held in mesh with the miter wheel 22 bymeans of the yoke .24. A cross shaft 26 journaled in the stud 21. and ina similar but sliding stud 27 at the opposite end 'of the member 12 is connected by miter vgearing to the gear 22 and to a similar gear 28 mounted on a shaft journaled in the stud 30. The gears 22 and 28 are on vertical shafts journaled in the studs 2l and' 30 and these vertical shafts carrybelt wheels 31 and@ mounted to bear against the mandrel with the already formed tube interposed between the mandrel and the rolls, and to press .down strongly the edges of the ribbon and smooth the edges into. a continuous surface or to smooth down. and press out t-he cement, glue or other substance that may be used, andmay have, because of thel previous pressure, eXuded slightly along the edges of the ribbon. A tube severing appliance islpreferably attached and is indicated under the general character C, but is not further referred to because it forms no part of the present invention.

The two pressure belts are driven by the shaftl 10 and inasmuch as it is desirable to change the angularity of the pressure belt to conform to the width of the ribbon that is used, and to the size of the mandrel that is employed, it isnecessary to provide not only for the adjustment of the tension of the belts but to provide for driving them throughout the extent ofthe change of angularity that may be given to them. In changing the angularity of the member 12 the stud which carries the belt wheels changes its absolut-e distance from the'aXis of the mandrel 4, and the shaft 10, which is parallel tothe -aXis of vthe mandrel 4: must change Vits absolute distance therefrom in the same amount. This is provided for by swinging the Ashaft 10 with the member 12 and making suitable provision to maintain kin mesh the gear' which drives the shaft A10,

Athe miter Wheel 8 on'its own shaft which.

is accomplished without losing its engaging relation with the miter gear 9, and the some- 1,oo4,121 l what similar yoke couplings 24 slide on the shaft 10 while remaining in pivotal-connection with the 4stud 21 and serving to maintain the intermeshing gear 22 and 25 in connection while the stud 21 serves to maintain the connection between the bevel gears 22 and shaft 26.

What I claim is l. In a tube-forming machine, the combination of a supporting frame, a mandrel, an oscillating member angularly adjustable across said mandrel and pivoted to said frame,l shafts, one of which is provided with a miter gear carried'by said soscillating mem-ber and having pulleys mounted thereon, a belt carried'by said pulleys and engaging around said mandrel, a -drive shaft having a miter wheel thereon,a miter gear.

splined on said drive shaft and intermeshing with said gear on said pulley shaft, means for holding. said gears in intermeshed relation, a second drive shaft disposed'at right angles tothe first-mentioned dr've shaft and having a miter wheel splined t ereon intermeshing with the miter Wheel on vthe firstmentioned drive shaft, means for holding said miter wheels' in intermeshed relation and means for rotating said second drive f'shaft, substantially as described.

2. In a tube-forming machine, having a suitable windingapparatus adapted to oscillate, :rgear thereon, a driving shaft having adrive connection with said gear movable lengthwise said shaft, a second driving shaft at right angles to said vfirst driving l shaft `and'having a drive connection therewith movable lengthwise along said second vso shaft, whereby the gear o'n said winding apv paratus may assume any point in the arc through lwhich it oscillates and he drive connections will adjust themselv s thereto without the shafts changing their angular relation, substantially as described.

In testimony whereof, I sign'this specii-` i cationin the presence -of twowitnesses.
