T 0 all whom' t may concern Be it known that I, JOHN IV. VINCENT, a citizen ofthe United States, residing at Kansas City, in the county of Iacksonand State of Missouri, have invented certainnew anduseful Improvements in VVeather-Strip- Forming Machines; and I` do declare the following to be a full, clear, and exact description of the invention,isueh as will en able Others skilled in the art to which it appertains to make and use the same, refer encebeing had to the accompanying drawings, and to the lettersand figures ofreference marked thereon, which form a part of thisspeci'fication.

This invention relates to a sheet metal working machine and particularly to means for cutting and crimping sheet metal in the form of weather strips in whichthe sheet is formed with a crimped rib or abutment at right angles to the plane of the sheet.

The invention consists in providing certain novel parts and combinations of parts, all of which will be specifically referred to hereinafter, reference being had to the accompanying drawings, in whichi F ig. VI is a perspective view of a machine constructed in accordance with my invention,part` of the feedtable yand sheet being broken away to show certain operating mechanismV therebeneath, and part of the crimping roller-housing being broken away to show the operating mechanism for the crimping rollers.

Fig. II is a cross sectional view on the line II-II of Fig. I.

Fig. III! is an enlarged elevational lview of a pair of the rib-forming rollers.

' Fig. IV yis a similar 'view of a pair of the rib-,crimping rollers. f

Fig. V is an elevational view of the sheet feed roller operating mechanism.

F ig. VI is a detail view of the finished weather strip, the product of the machine, and 1 Fig. VII is a top plan view of a rmachine constructed in accordance with my invention.

, In the illustrated embodiment of the invention I have shown a frame consisting of a table 1 vsupported upon standards or legs 23, 4 and-5. Projecting upwardly from the table -1 arev slotted standards 6 and 7, in which is a vertically movable reciprocatory knife, 4resting upon the expansion Speecatonof Letters Patent.

Application filed March 26, 1920. Serial No. 368,922.

springs 9.and 10 Aand engaged by the upper ends lof the` pitmen 11 and l2, which are connected to the cranks 13 and 14 on the rock shaft 15, mountedy in bearings inthe standards or legs `3 and 5. f

The rock shaft 15 is provided with a crank arm 16,y projecting` inwardly toplie in the path yof the roller Vor projection 17 on the rotating disk 18, rigid on the shaft 19` in ybearings l2() and 2l. Thel shaft. 19 is rotated by a sprocket chain which passes around a sprocket 22kon shaft 19 and around a sprocket 23 on shaft 24, in bearings 25 and 26, ,supported from, the standard .3 and table 1 respectively (see Fig. I). I

The shaft 24 carries a pulley 27 driven by a belt 28 from the motor 29 on the bracket 30, carried `by the machine frame. Therefore-,when the motor is operating, the shaft 19 will be rotated, causing the roller or projection 17 to intermittently contact with the crank arm 16 to operate theV knife 8 against the action of the springs 9 and 10 and after the roller or projection 17 has moved Ofl" the crank arm 16, the springs will raise the knife 8 and, through the medium ofzthepitmenjll and 12, the shaft 15 will be rocked so as tov raise `the arm 16 lin a position vto again be actuated by` the .projection or roller 17, when it reaches contacting position during each cycle of its operation. e

Means is provided fork feeding `the sheet across thetable so that theknife mayshear it. The means illustrated consists of an idler roller 31, co-operating with a positively driven roller receiving its motionfrom a pulley 33 onV shaft32. The pulley is driven through the vvmedium of a belt 34, passing around the pulley 35 on shaft24 and it is adapted to rotate `the roller 36 to feed the sheet37 toward the knife. When the knife has severed'thev sheet, it will drop `into the trough-shaped guide 39 and be engagedby the rollers 42 and 43. Sincek the distance between the rollers 42 and 43 is slightly less than the width` of the severed strip.v the `strip will cup slightly and itsedges will spring into the

grooves

40 and 41 in the rollers 42 and 43 so that the rollers will vguide and deliver it tothe forming rolls.` 'Ihe roller 42 is driven from a shaft 44, having a `gear 45 meshing with a gear 46 on shaft 24, so that the edges of the severed sheet will be frictionally engaged by the floors of the

grooves

40 and 41 and be fed to the rib- Va positively forming rollers, there being threesets of,

rollersillustrated. in the drawings, said, sets bearings 59 and Y when vthe shaft 24 rotates, the shaft 63 will medium ofthe gears,

rotatev and through the 48 and 49 Vor ribwillfdriye the `sets' 4T, forming rollers.

IIn'actlualf practice the ribs and grooves of the respective 'sets will be progressively di- 'Ininishech` thatfis, there will befafrelatively widerib and a relatively wide groove forv the iirst'set47, and-a relatively thin groove and La correspondingly thin flangel 561f`0r the succeeding setsof-rollers sothat the sheet or strip willbe first formed into shape to provide' thel rib 66 for the strip 67` with the groove 68`relatively wide, but as 'the rib 66 progresses vthrough the respective sets of formingf rollers 47,' 48 and" 49the sides of the yribsV will be drawn grooves'fwill beV relatively narrow. Further progression ofthe sheet 67 will move the rib between the crimpingV rollers in thehousing 69 so that the sides of the rib` 66 willbe crimped together with the' inner ,sides off the tactto afford a slight spring'or'give to the rib 66.7 Y

'llhecrimpingrollers are shown as consisting of two pairs, one pair comprising. a flanged idler roller` 7 2 mounted in bearings the hu'sing69 and a positivelywdriven flanged roller 73, 'also mounted in bearings inthe housing on a shaft v74, the shaft 74 carrying gear 751meshin'g with an `intermediate gearv 7 6, which in turn meshes Vwith a gear 717 on the shaftV TSFOf-the flanged roller 79of the second set, theflanged rollerv 79 having-'a complementaryidlerroller 80, also mounted vinV they housing- 69 and correspondiiig'to; the rollersf72. The' gears 75 and 77 receive their motion from thesgear 76, which ifsldriven by a gear V81 on thefshaft63. The housiiig69 is provided with a slot 82 through which the finished strip may pass onto the table83. f

The roller 86 is not continuously driven but' its shaft 36 ycarries a ratchet 84 adapted tobe lintermittentlyl engagedA by a pawl 8 5 on the lever86, normally retracted by the spring 87, there,'also being a spring88 betwgeenthe` lever and the pawl. The lever 86fentends radially from the shaft', on

circumferential rib or flange 56 oftogether until the Y portions andV 71V not quite in intimate con.

Y nism,

which it is loosely mounted so that the pro-V jectionlv 89 on, the pulley 32 A may intermittently contact with.V it and rotate the shaft 36 a suiicient distance to allow the sheet to feedfone width ofthe strip to be formed into 70 vthe finished product during each cycle of operation so that the sheet 'is intermittently fed to the groove l39 as it is traversed longitudinally of the machine and while the feeding step istruly intermittent, theA operation is substantially continuous for as fast-as the sheet is cutinto strips, it isfedinto the forming and crimping rollers'l to make the finished" product.

The feedv operating mechanism shown. in Figz`V'will rotate vthe driven roller 36. to feed the sheet 87 a certain `distance intothe machine, the. extent ofthe feed determining the width ofthe weather strip to be formed; Different widths ofweather strips may ybe made by changing the feed mechanism to govern the extent of movement ofthe sheet, as will'be wellunderstood.V

From the foregoing it will be seenthatas the sheet is fed Vbetween the rollers 31L and- 86itl willbe cut, then fed longitudinally to the forming rollers andV froml the forming rollers to the crimping rollers, makingthe weather strip in the form shown in Fig. VI but with the sides *mand 7l practicallyv intimate contact. v
