CHUCK FOR MANUFACTURE OF FINNED TUBING Filed Oct. 25, 1947 3 Sheets-Sheet 3 Em. A. 5CHRYBER INVENTOR.
3 The angular or pitch adjustment of the rolls is accomplished in the illustration through the provision of worm gear elements slidingly keyed at 3! on the yoke spindles l1, l8, l9, and confined in cross slots 32 inthe yoke bearings 25, 2!, 22, these gears being engaged by the worms 33 34, 35, keyed on the ends of stub shafts.
36, 31, 38, at the front of the head or frame I these shafts carryin at thefback of this plate rock arms 39, 40, 4|, connected to be operated in unison by links 42 and 43.
In the illustration an adjusting lever 44, Fig. l, is faced on shaft 38 registering with an adjustment scale on the front of the frame plate. This lever is shown equippedwith a handle 46 for actuating the same, slotted at 4! for passage of a securing and movement limiting bolt 48.
The frame or face plate 1 is shown as having screwopenings 49 to receivethis bolt for limiting the adjusting lever to different ranges of mo-vement over the scale 45. The links 42 and 43 are shown extending, respectively, from the rock arm 4| to the rock arms 39 and 40 of the shafts 36 and 3'7 for effecting adjustment of drive roll 9 and pressure roll 8.
When the holding screw 48 is released, hand lever 44 can be used to rock shaft 38 to adjust the angle of drive roll l0, and this shaft through the lever and link connections with the other .two
shafts 36 and 31, will effect corresponding angu- I" bolt 48 may be withdrawn. and the lever 44 set L in an extended position where" the bolt may be entered in another one of the screw seats 49 provided in the scale plate. 7 r
The mechanism for operating the drive rolls is shown as comprising a main drive shaft 59 operated by chain and sprocket 5|, this shaft carrying a pinion 52, Fig. 3, meshing a gear 53 carrying a pinion 54 in mesh with a'gear 55 which, as shown in Fig. 6, meshes with gears 56, 51, at opposite sides of the same, these being fixed on shafts 58, 59, and coupled by extensible, universally jointed shafting with the shafts 60, BI, carrying the drive rolls 9 and Hi. Fig. 5 shows in detail one of the extensible, universal jointed shaft units, comprising an intermediate length of tubular shafting 52 connected at opposite ends with the final drive shaft (58) and with the roll shaft (59) by universal joints 63, 64, said sleeve having a splined or sliding key connection at one end to allow for necessary extension and contraction of the overall shaft length in the various adjustments of the drive roll.
The extensible and universal drive connections disclosed enable operation of the two lower drive rolls regardless of the in-and-out and angular adjustments of these rolls.
surfaced to best perform their particular purposes. The drive rolls 9 and Ill may be knurled, toothed or roughened to grip the work and the pressure roll may besmooth, substantially as indicated. 3 l
The rolls being set to properly grip the work and inclined to the proper helix pitch angle, it will be evident that they will roll and longitudinally advance the tubing at a rate in correspondence with the rate of advance of the fin strip being helically wound on the tubing, and it will further be evident that by simple adjustments of the hand lever 44 all three rolls may be simultaneously adjusted to the same extent, to difierent helix pitch angles.
The structure is particularly simple and the rolls are exposed so that the action can be observed and correctionsmr adjustments quickly made as conditions may require.
What is claimed is:
l. A chuck for helically feeding tubing for application of a finning strip thereto and comprising a guide for centering and axially directing a length of tubing, substantially radially disposed bearings about the axis of the guided tubing, yokes having spindles longitudinally and ro-' tatably adjustable in said bearings, rolls journaled in said yokes for engagement with the application of a finning strip thereto and comprising a guide for centering and axially directing a length of tubing, substantially radially disposed bearings about the axis of the guided tubing,
; yokes having spindles longitudinally and rotat The drive gearing, as shown in Fig. 3, may be enclosed within a gear case 66.
This View also shows how a guide bushing 6'1 of proper size for the tubingll may be secured by clamp screws 68 in a seat or bearing 69 provided for it in the frame structure.
The rolls for supporting and driving the tubular or other core stock may be plain or specially ably adjustable in said bearings, rolls journaled in said yokes for engagement with the guided tubing, means'for driving certain of said rolls; regardless of longitudinal and rotary adjustment of the yoke spindles and means for effecting simultaneous rotary adjustment of the spindles in said bearings including. worm gears slidably keyed on said spindles, said bearings having transverse seats receiving said worm gears and rotatably confining the same against longitudinal movement in respect to the spindles, worm ele: ments engaged with the respective worm gears and linkage tying said worm elements together for insuring simultaneous angular adjustment of all the same.
3. A chuck for helically feeding tubing for application of a finning strip thereto and comprising a guide for centering and axially directing a length of tubing, substantially radially disposed bearings about the axis of the guided tubing, yokes having spindles longitudinally and rotatably adjustable in said bearings, rolls journaled in said yokes for engagement with the guided tubing, means for driving certain of said rolls regardless of longitudinal and rotary adjust-.
ment of the yoke spindles and means for effecting simultaneous rotary adjustment of the spindles in said bearings, spring means forcing one of the roll carrying spindles toward the tubing axis, means for positively setting other roll carrying spindles toward the tubing axis and means interconnecting said spindles for rotatively adjusting the same in their bearings independently of the described longitudinal adjustment of the spindles in respect to the tubing axis and thereby enabling the simultaneous setting of said rolls at a desired feeding angle to the tubing irrespective of the diameter of the tubing.
4. A chuck for rotating and longitudinally ad- Vancing tubing to which finning strip is being helically applied and comprising three tubing engaging rolls grouped in triangular relation about the axis of the tubing, yokes in which said rolls are journaled, said yokes having spindles, bearings in which said spindles are longitudinally and angularly adjustable, worm gears slidingly keyed on said spindles and held in said bearings against longitudinal movement, worm elements in engagement with said worm gears, links connecting said worm elements, means for imparting angular adjustments to one of said worm elements and whereby through said linkage corresponding adjustments will be imparted to the other worm elements, said spindles having reduced outer ends, screw sleeve abutments about said reduced outer ends of the spindles and REFERENCES CITED The following references are of record in the file of this patent:
