Application inea August 5, 1925. senat No. 4am.

The present invention relates broadly to the art oi' metal Working, and more particularly to apparatus generally referred to. as reels effective for coiling strip material, 6 the expression strip material being used .in

its generic sense as being definitive' of different structural shapes having suoli characteristics that it is desirable to coil the same.

At the present time it is customary in the 10 art to which the present invention relates to provide mechanism for coiling strip material, either for the purpose of facilitating liandlingand transportation thereot' or for the purpose of breaking the scale to insure or both. The present invention Irelates broadly to apparatus ot this character, and for purposes of illustration is in one instance Ashown as applied to a reel of the character disclosed in the patent to Florence C. Biggert, Jr., No. 1,492,954, of

May 6, 1924, and in another instance .1s

shown applied to a reel of the character disy closed in my prior Patent No. 1,462,411 of July 171923, although it will be apparent '-5 that the utility of the invention is not limited with respect to the particular construction of the reel with which it is used.

In reels of the 'general character shown in the patents referred to, pressure is continuao ously maintained on the material being coiled by the action of pressure actuated means in the form of levers or rollers, or a 'combination of the tivo, having a resilientconnection with a cage common to all of the pressure actuated means. This cage in tuin has an operative connection with a s fluid pressure cylinder adapted to move the same as may be required at predetermined periods in the operation of the reel, and

40 i adapted during the coiling operation to coms` pensate for increased pressure exerted on the pressure actuated means by the increase in the diameter of the coil and thereby maintain a substantially constant effective pressuretliroughout the ceiling operation. In actual practice, and particularly Where the reel is being used for the coiling of strips of ditl'ereiit widths, it has been found necessary to ve carefully and accurately con- 5o trol the fluid nressurein the cvlinder constitutingthe compensating means. This has required almost constant attention on the part of the operator andmakes the apparatus objectionable to some extent by reason of the attention thus required.

The present invention has for one of its objects an improved form of compensating mechanism adjustable to adapt the ap aratus to a Wide range of material and e. ec tive in such manner as to make accurate con# trol of the luid pressure unnecessary.

In tlie accompanying drawings there are shown, for purposes of illustration only, certain preferred embodiments of the present invention, it being understood that-the drawings do not define the limits of my invention, as changes in lthe construction and operation disclosed therein may be made without departing either from the spirit of the invention or the scope' of my broader claims.

In the drawings:

Figure 1 is an end away and partly in section, illustrating one f orm Vof reel embodying the present invention;

Figure 2 is a View similar to Figure 1, illustrating the parts in the position they assume upon completion of the coiling operation;

Figure 3 is a. detail View, on an enlarged scale, illustrating the lost motion and resilient connecting means between the compensating cylinder and the cage; and

Figure 4pis a view similar to Figure 1, illustrating the invention applied to a reel ot the character shown in my priorpatent referred to.

The general construction of the reel shown in Figures. 1-3 is similar to that disclosed elevation, partly broken .in the patent to-Biggert No. 1,492,954, and

tion by the use of Spacer sleeves 5-through which may extend bolts 6 asunderstood in the art.

In operation the shaft 18 may be driven in any desired manner,l but preferably at a speed greater than the speed 'ofthe rolls 21,

As the material builds up on the ycollapsible mandrel or core, it is engaged bythe rollers 16 and the guiding portion 17 of This causes the pressure actuated means to A move outwardly as the'diameter of the coil f increases, this outward movement being resisted by compression springs 23 surrounding the bolts 9l and bearing at one end against fthe; bearing blocks 10. and at the opposite end'.

-the piston in th the pressure actuated means, but that they permit such vpressure actuated means to move outwardly relatively to each other and relatively to the cage 7, should such movement be necessary. The guide 22 similarly moves outwardly thereby beingautomatically maintaine in position to most effectively guide the material.`

If the cage 7 is held against any movement during .the coilin pressure exerted y the sprlngs 23 continuoperation, the increasing ously changes the yoperatlng characteristics i of the pressure actuated means. lIn order to overcome such. a condition of operation it has heretofore, been-proposed, as illustrated in the patent 'referred to, to 4provide a fluid pressure compensating cylinder 24 o erativeyconnected to the cageand adapte .to'per-l mit rotation thereof against the pressure in the cylinder. lReferring to Figures 1 and 2 of the drawings', it will be apparent that as the coil increases in diameter the cage would have a tendency to rotate in a clockwise di vrection andthereby compensate for the compression of the springs 23. In actual operation, however, it has vbeen found that -it is necessar to accurately control the fluid pressure in the cylinder and makechanges in this duid pressurein accordanc'ewith the cross sectional areaof the material being coiled. This has required extremelyv close regulation of theluid pressure on the part of the l operator and has necessitated almost oon- 4stent attention durin the coiling operation. l In` accordancey with the resent" embodi` ment of the invention, this o jectfionahle feathe cylinder is obviated by providing a resiliently controlled lost motion connection between the cylinder and the ing the arms 12 of one of the pressure actuated means to a point outside of the cage 7 afllid providing a pin 25 extending between t a piston rod 27' proJecting :from-the fluid' -pressure cylinder 24. The piston rod ata pointintermediate its endsmay be rovided a crosshead 28` guided in suitaili) ways 29 on the base 2 of the reel for relieving the piston rod from tortional strains. Itwill Thismay be accomplished by extendearms and journaled therein. This pin f 'extends through ay slot 26 in the outer end of le slidebe apparent that the slot 26"constitutes a lost motion 'connection between the pressure actuated means and the fluid pressure cylinder. 'Due tothis lostl motion connection t e ressure actuated means, may move outwar v as before described without-the neced" sity of actually Vproducing' any movement of e cylinder 24. The length of the slot 26 is preferably such as to permit substantially fulloutward movement of the pressure actuated means before the lost mo- .'tion is completelytaken up.. Thereafter,

ifoutward movement of the pressurev actuated me'ans continues, the cylinder will come 'into operation and compensatelfor Compression on as bolts 31. With la plate 30 rigidly secured to the outer end of the piston rod 27 by suitable means, such this construction the plate 30 is held against movement relatively to the piston rod. The pin 25 passes through links 32 secured to a movable crosshead 33. This movable crosshead may have projecting therefrom one or more uiding sleeves 34 extending through Vsuitable openings in the plate 30 to guide the relative movement between the crosshead and the plate. Also carried by the crosshead is a plurality of rods 35 herein illustratedas being five in number and each having a threaded outer end 36 carrying a thumb nut 37 adapted to be threaded to different positions on the rods" to vary the compression lor initial load on springs 38 carried thereby, In the illustrated embodiment of the invention, springs 38 are shown as being mounted on only two of the rods 35. It has been found that such a construction may-.be very effectively used with strips up to 8 inches in width. For slightly wider strips, springs may be added to thecentral rod 35. Under still other conditions of operation, springs will be applied load on the "springs be just sufficient toclose the reel by moving` to the four outer rods only, while for strips of maximum widththe springs will be appliedto all of therods. Preferably, under Aall conditions of operation springs will be maintained on therrods as illustrated in Figure 3, irrespective of what other rods may have springs applied thereto, and the initial on these two rods will 'the pressure actuated means to the position k"so .which will gra on the springs shown in Figure 1, and to take up the slack on the other springs". Thereafter, as the diameter of the coil increases the pin 25 will tend to move tothe left, as viewed in Figure 3, thereby carrying with it the crosshead ually increase the load on the springs 38.I This building up of the load 38 will in turn control the movement of the cage 7 in a clockwise direction, as viewed vin Figures 1 and 2, and pro vides acompensatin means in lieu of the fluid pressure cylin er effective for` main-l taining a substantially constant compression on the springs 23 throughout the ceiling operation. By initially determining the roper number of springs 38 and the initial oad thereon, it is possible to the right operating conditions for strips of different characteristics and thereby enable the use of a wide range of pressures the fluid pressure cylinder. Upon the concluobtain exactly sion of the coiling operation it will be ob-` vious that the-fluid pressure cylinder may be energized lfor bodilymoving all of the pressure actuated means out of contact with the coiled materialto permit discharge of the same. This concludingmovement accomplished by the fluid pressure cylinder is indicated in dottedA lines in Figure 2 of the I drawings. 4 v f It has also been'found desirable to provide means for counterweighting the pressure actuated means. `Thls. counterweightingIv be accomplished `by ex-l may conveniently tending the arms 12 of one of the .pressure actuated means and securing a counterweight 39 to the extended arms. This countcrweight will preferably be substantially of the order of the weight of the pressure actuated means so as to substantial] exactly balance the same. In the event tiecounterweight actually underbalances the pressure actuated ymeans, this underbalancing may be taken care of by slightly increasing the initial load on the springs 38,-while if thecounterweightslightly overbalances the pressure actuated means the initial load on the., springs 38 may be correspondinglylessenedal 'l It will bea parent that the operation herein obtaine by directly securing the counterweight to one of the'pressure'actuated means and directly connecting'gthe fluid pressure cylinder and the resilient ycompensating means to another 'of the pressureA actuated means is broadly the e uivalent `of that which would be obtained, y directly counterbalancing the cage 7 or making con nection to the cage 7 for the fluid pressure cylinder as disclosed in the patent previously. referred to. v A In Figure 4 vof the'draw-ings there is illustrated a form of the inventionin whichthe counterweight and the resilient compensating means are so secured in position that they are effective simultaneously on all ot the pressure actuated means, as vwillv be the case in the preceding figure if these parts' were directly secured to the cage and the intermediate springs 23 omitted entirely. In this figure of the drawings, parts correspondin to the arts already described are designated by the same reference numerals, having, however, a prime aixed thereto. The operation of the reel disclosedin this embodiment issubstantiallyI the same as that lreferred to, the material being fed forwardly into a guide 22 by means'of pinch rolls 21- into the space defined by the shaped ends '17 of the levers 15. In this embodiment of the invention no core is ro-vided in the ceiling;` space, the rolls 16 being positively driven in a suitable manner, as disclosed, for example, in my prior Patent No. 1.462,411, before referred to. The arms 12 of the various pressure actuated means. vare directly andrigidly interconnected by the rolls 16 and y means of linlcs (i0, whereby all of the rolls lo move outwardly' or inwardly in unison. in addition to tbc movable rolls, there is preferably provided a roll fill adjacent the guide Q2 which is stationary, this roll defining at all times a predetermined point in the periphery of the material being coiled, 'to thereby obviate the necessity of providing a movable guide.

It will be apparent that inasmuch as the counter-weight 39 is directly secured to one of the arms l2 which is in turn rigidly interconnected with the other arms, all of the pressure actuated means must move in unison. ln like manner the compensating means is effective, as liereinl'iefore pointed out` for simultaneously acting on all of the pressure actuated means` .llie advantages of the present invention arise from the provision of a reel in which the compression exerted during the ceiling,y operation may be maintained substantially constant, irrespective ot' changes m diameter of the coil and in 'which the compensation eilected by resilient means, accommodating' itself' to a Wide range of material.

Further advantages are obtained by pro vidinp; a fluid pressure cylinder having a lost motion connection with the pressure actuated means.
