COIL RAMP WITH MOVABLE RELEASE SADDLE United States Patent@ 2,737,306 WITH MovABLE RELEASE SADDLE- 'lisgfeif vi'ig, Cricngn,v In., assigner mi; j. Litfii lune Company, Chicago; Ill., a corporation of M The invention relates to improvements in ramp structures for coil loading reels and has referencein particu` lat to acoil ramp having coil release means in the fori-mof a movable saddle. lIn one form of the invention the movable saddle is combined with stationary saddles for supporting the coil and holding the coil stationary in advance of its release b'y the movable saddle.

In the past a number of devices have beenl employed for holding and releasing a coil of metal stock supported on a `ramp leading to a cradle type reel. The simplest method consists in .providing a dog which protrudesup'- wrdly from the ramp into contact with the coil and which i`s withdrawn by hand for releasing the coil. Other variations have included several such dogs so t-lat the` oil would be held and released in better alignment.- Also .the .same have been constructed witli ltogglesf'to gain additional leverage for releasing Ythe coil; Air cyliiiL ders have been provided in combination with releasing pavvlsy for safety reasons since the use of a hand operatedr lever is eliminated. Steel mills have constructed release with a large section of the ramp tilting upward to form the' locking sui-'face and when retracted the locking sur; faces become a portion of theV ramp propel".

The developments above mentioned have in everyl case simply released the coil, allowing the same to roll downthe rampunder the action of gravity. However, lthis mode of operation has at least one inherent diiculty, namely, lthatwith the coil at rest one is faced with tlie enormous weight of the coil, and due to the coetlicieiit of static friction the tendency of the coil is' to' tem-ainai rest. This mustbe overcome in order toj produce rolling movement of the coil on the ramp. 'Even` fairly' steep ramps it is a common occurrence to employ a' crow bar to start the coil rolling. However; 'once a coil is started rolling it seems to roll do'wn a very slight incline without any trouble. Accordingly, another 'de'-A velopment has been the additional use of a 'pusher' linger behind the coil so thatup'on release' 'of the'lio'ldng or `deg the coil was given anpin'itial push to' overcome its static inertia and startv it rolling.

A In view' of 'the ,foregoing a general object of Athe present invention resides in the provision 'of 'an improved cuil supporting ramp having novel coil release nieans' in the ferm of a pivoted saddle" 'which is elevated to' tneeusl-y release the coil and start it ruil-ing` down 'tire ramp. K Y

Another and more specific object 'of vthe present' inf ventio'n resides in thepr'ovision of a 'snpportin'g ranp for supporting coils of metal'stock prior to loading tli onto a cradle reel and wherein the ramp is provided with stationary saddles for supporting the 'coil an'd'wit'h-v a movable saddle for releasing the coil.

fice

`Another object of the invention is to provide a` movable saddle having a V-shaped coil supporting surface and wherein the movable saddle is conveniently elevated by air pressure to release the coil and impart initial rolling action thereto to start its movement down the ramp.

Another object of the invention resides in the provision of a coil ramp havin-g supporting and release saddles of improvedl construction and operation, and wherein an end gauge is incorporated therewith so that the coil upon being: initially loaded on the ramp inv supported with the stationary `saddles thereof will be properly positioned centrally of the ramp andY approximately centrally of the movablensaddle which has location between the station ary saddles.

Another object of the invention is to provide an improved coil ramp that can be secured to its coil loading reel so that the' structures are in perfect alignment for the: most satisfactory and efficient operation.

Another object is to provide a coil loading ramp hav# ing connecting means for pivotally joining the same to its coil loading reel, and wherein limited pivotal actionbetween the ramp and the reel permits adjustment of the inclination of the rampV to suit individual requirements,v and which is accomplished without losing perfect lig'ni mentbet-ween the structures.

With these and various other objectsy in View, the in* vention may consist of certain novel featuresof con: struction and operation as will be more fully descrilied and particularly pointed out in the specication, draw ings and claims appended thereto.

Referring to the drawings, one 'embodiment of. the invention selected for illustration is disclosed in Figure Vl in combination with a cradle type reell generally indicated by numeral 10 and including spaced side members `11V joinedby yfront wall 12. The side members 11 suitably journal the coil supporting shafts 13 and 14, which are operatively connected so that they rotate in unison and which are conveniently driven by the motor drive unit by connecting chains or pulleys not shown. The motor drive unit is motor driven and includes speed variating mechanism capable of adjustment by the hand wheel 16 to select the proper speed of rotation for thersupporting shafts 13 and 14. The side members 11 suitably journal a pair of rotary guide plates 17 and 18, each plate being rotatably mounted by means of hub 20 on a shaft 21 supported by its respective side member 11 for movement laterally of the member. By means of the electric motor 22 and the gear mechanism 23 it is possible to effect lateral movement of each shaft 21 in order to position the rotary guide plate for receiving a coil of metal stock. In operation the rotary guide plates 17 and 18 are spaced a distance sufficient to receive therebetween the said coil of stock and then the motors 22 are actuated to bring the rotary guide plates into contact with the respective sides of the coil. As a result the coil is supported and rotated by the supporting shafts 13 and 14 and the side edges of the coil are protected by means of plates 17 and 18 which accordingly rotate with the coil as the strip material 24 is withdrawn therefrom.

The ramp of the invention essentially consists of a coil supporting portion and a ramp or inclined portion, the two portions having articulated relation with each other, as will be presently described in detail, and the ramp portion being pivotally secured to and supported by the rear wall 25 of the reel. The said ramp portion essentially consists of a flat plate 26 having reinforcing webs and ribs integrally secured to the underside thereof, and having a longitudinally extending slot 27 located centrally of the plate for receiving the loop control arm 28. The ribs on the underside of the plate 26 consist of side ribs 30 and 31 which extend from the forward transverse rib 32 to yand beyond the rear transverse rib 33. Substantially centrally of the plate and on respective sides of the longitudinal slot 27 the plate is reinforced on its underside by ribs 34 and 35, the same being joined by the transverse web 36. The extreme forward end of the plate 26 is pivotally supported by means of the bar 37 which is suitably secured as ,by welding to the rear wall 25 of the reel. A number of vertical openings are formed in the bar and securing bolts such as 38 are employed in fastening the ramp plate 26 to said bar. The openings provided in the bar 37 are somewhat larger than the bolts 38 passed through the opening and the structure accordingly provides for limited Vertlcal adjustment of the rear end of the ramp in order to increase or decrease the inclination of the same.

The slde ribs and 31 were described as extending rearwardly beyond the transverse web 33. The rearwardly extending portions of the ribs receive and journal the shaft 40 which serves to pivotally join the supporting portion of the ramp to the inclined section. Rear flanges 41 also extend rearwardly of the rib 33 and are integral therewith. The anges are apertured for receiving the shaft 40 and the same therefore additionally function vas journalling means for said shaft.

The supporting section of the present ramp consists of a pair of stationary saddles and a movable saddle, the said statlonary saddles being spaced with respect to each other and having the movable saddle located therebetween. As best shown in Figures 2, 3 and 4, the stationary saddles are provided with a bottom plate 43 to which is integrally secured the stationary saddle 44 and the stationary saddle 45. Both saddles are similar in construction, each consisting of a pair of plates 46 and 47 associated with each other in a manner to form a shallow V. The size of the V formation is substantially complementary to the circumference of coil 4S which is adapted to be supported onV the stationary saddles. Each saddle is completed by the side plates 50 and 51 which rest on the bottom plate 43 and suitably support the plates 46 and 47 of the saddle at the desired height. The side plates 50 and 51 of each saddle are reinforced by the transverse standards 52 and and 3.

`respects conforms to the V formation of the stationary saddles. The saddle 54 is reinforced on its undersurface by the longitudinally extending ribs 57 and 58 located at respective sides of the saddle and by the intermediate ribs 60 and 61. All the ribs are joined by a forward transverse plate 62 and by a rear transverse plate 63. The transverse web 64 extends between and connects the ribs 60 and 61 adjacent the rear thereof. The movable saddle 54 is pivotally supported at its forward end by means of shaft 40, which shaft extends through the journal bearing 65. The said bearing forms part of the movable saddle since the bearing is suitably secured to the saddle by being welded to the transverse plate 62 for the length of the same. Movement is imparted to the rear end of the saddle 54 by any suitable means such as an hydraulic cylinder or air cylinder indicated in its entirety by numeral 66. The usual piston operating within cylinder 66 provides the piston rod 67 and pressure uid is admitted and exhausted from respective ends of cylinder 66 through pipes 68 and 69.

It is necessary to support the power cylinder 66 for rocking movement and for that reason the circular band or strap 70 is suitably fixed to the cylinder, being held in secured relation therewith by bolt 71 and being disposed below and in contact with the top Wall of the cylinder. The circular band 70 provides the diametrically extending pintles 72 which are journalled by sections 73 of the standards 74. The individual sections 73 are releasable from the standards to permit assembly of the parts for pivotally mounting the power cylinder, and after the sections have been located on the pintles 72 they are tixedly secured to standards 74 comprising the side arms of a yoke member which includes the supporting base 76, the same constituting a part of and being integral with the bottom plate 43. The movable saddle is provided with rearwardly extending spaced webs 77 which are integral with the plate 56 and extend rearwardly of the saddle in substantial alignment with ribs 60 and 61. At the extreme rear endof each web the same is provided with a hub portion 78 which is apertured for receiving pin 80 by means of which the movable saddle is pivotally secured to the piston rodv 67. It will be seen that energization of power cylinder 66 in a direction to project the piston 67 is communicated to thefmovable saddle, causing pivotal movement of the saddle in a counterelockwise direction, Figure 4. Also energization of the power cylinder to retract the piston rod is likewise communicated to the movable saddle, ef-

fecting pivotal movement of the same in a clockwise direction from an elevated position to a lowered position.

VThe loop control arm 28 is suitably fixed to the transverse shaft 82, passing through opening in the ribs 31 andv 35 and being journalled thereby adjacent the forward end of the ramp 26 and on the left side thereof. The handle 83 is suitably fixed to the outward projecting end of shaft 82 and it is possible for the operator by actuating the handle to retract the loop control arm. However, when the arm is free it is caused to assume a position approxi-v mately ve to ten degrees from vertical and which action is eifected by the balancing weight 84 fixed to rod 85, which is suitably secured to shaft 82 and positioned with respect to the loop control arm 28 so as to depend vertically under the action of weight 84 when the arm is located slightly off the vertical, as clearly illustrated in Figures lj The loop control arm is adapted to control thel size of the loop being fed from the coil supported by theI cradle type'reel 10. When the arm is upright, as shown 'are in Figures 1 and 3', jitwi1 1be ttiidersjtoodthet the' unit energized 'and t a" supporting sliaft7 are being' rotated tol ermeeV the oil irr diel cradle type 4rie-:e1 to rotate eind peg' out stripF materiel. should the free outermost loop in contact with the arinincre'asein size beyond' a predetermined maximum, se'e' Figure A1.,y the control arm will be depressed, whereby 'operation ofthe rno'to njni't' driving the' supporting shafts" 13 `and 14j `is dlsoontinued.

The electric circuit to said' motor unit isV established again at a certain elevated position of 4the arrn 28 'when lthe cam 87 moves out of contact with lever 88. i y

Itis desirable vto provide a stop member for the coil 48 in order that the oprator in depositing the oil n saddles will know when the coil is positioned substantially centrally f the ramp and also centrally of the movable saddle 54. It will be understood 'that the coil of stock 48 is deposited on the coil supporting portionl ofQthe ramp from the side of the same, and,l assuming that the coil is deposited from the left side of lthe niachine, as 'viewed from the rear, Figure 2, Athe 'stop willbe located in associated relation with the stationary saddle 45. Accord;` ingly, the invention provides a stop supporting rod 90 which is suitably supported by the extensions 77, the same having openings formed therein for receiving l'the l'rod 90 and which isl xed theret'oby set screws 91 As'shown in Figure 5, the said rod 90 extends in a direction toward the right and the stop member 92 is mountedthereon and fixed in desired adjusted position. The stop 92.4essentially consists of a split yoke having the said stop 92'- integral therewith. Bymeans of the split yoke the same is assembledon rod 90 and is locked in adjusted position on' the rod by means of screw 93. m l

During operation of the cradletype reel 10 a coil of stock such as 48 is held inl reserve, being supported onJtlhe stationary saddles 44 and 4S of the pr'esent ramp. The coil 48 may be deposited on the supporting saddles by any suitable means such as a crane orlifter truck. yThe stop member 9 2 is positioned on rbd 90 seas to `position coilv 48 centrally of the ramp structure. The particular posi' tion of stop 92 is determined by the width of the coil- 48 and fora coil of different width i t would be .necessary to change the location of thestop. In fact, for narrow coils which would be wholly supported by the movable saddle, the st'op might have a position overlying the plate 56 ofthe lmovable saddle. The supplyof air pressure to the power cylinder 66 is controlled by the foot switch 95 which controls an electric circuit including the solenoidl actuated valve 96. The electric circuit incorprates .an interlock to be presently described which renders the foot switch operative under certain conditions. When operative said-foot switch will actuate the solenoid valve- 96 to supply fluid under pressure to pipe 69, connecting with power cylinder 66 whereby to project the piston Mrod and elevate the rear end o f the pivoted saddle 54. When the foot switch is released the solenoid valve 96 automatically returns to its initial position,- whichexhauststhe airV vfrom pipe 6'9", allowing the piston rod yand the pivoted saddle to return to retracted position. i y

. 'lhe interlock above mentioned is combined with lthe loop control arm 28. It is necessary to irst retracttlie Gif l satisfactorily provided for inthe past am 28. Before de" Accordingly, the fi er `vjckp 'ed saddle into anI elevated posi arm has been retracted to `a' p u V 'V Figure 4. It is necessary' for' the voperator to :rhone tlief arm into said position by movement of the handle 83 "nd as a result the c'am 97, fixed to' shaft 82, is' caused tti/ contact the switch lever 98 of 'tl'rernieroswltjc'h'-10'0- n actuation of the ni'eroswitcl loothejntelocki inoperative, or, in other words, the' electric circuit tof t switch 95 is closed and' up'on actuation of the fooit'swtcli' solenoid 96 will 1re errergried to effect actuation of e power cylinder a-ndelevation'of the; saddle 54, as described. The inventlon provides an' au matic release for the' loo'p control ar'rn 28 Vafter t has" rolled down the ramp and over tli'e n n n `it the cradle type reel.

The c'oil ramp of the invention embodies l f improved featil're's.-v The provisie 'afpaii'l` of.v Vlfsh ldy saddles n which the` Coll is iliill 1y p'Iad'l'S fhfad vantage of supporting 'the coil in a stationary Also the saddles help to vnlinifrliie damage 't tli i Ac'o'll s uch as may result frorn placing the coil onthe saddles;t The' coil isY generally dropped o r deposited with considerable impact and the shallow V formation of thesaddlfes stantia-lry conforms to the contourv of the coil. yThe pivoted release saddleis convenientlylocated between the stationary saddles and its movement is such'that saddle ris elevatedi't initiates rolling action .of .tli`e` co1lf down the ramp. It' hes been foroid that' the 'eenfe'rjof fire i coil is advanced in a `forward direction approirirnately sini inches by elevating the vmovable saddle. Inv other the elevation of the movable saddlet'ran'srriits a distinct forward velocity to uthe' coil, thereby (adding mornf :rfltlrr'` to the coil as well as placing the coil in a condition moving friction insteadof` static friction. AnotliF desirable vvfeature resides in the perfect aii'g'nrirent which is effected between Athe ramp and the reel. In (Seinf-4 nection, it may be lnoted that thev supporting' portion of the ramp may be eiev'ated"somewhat.byylocatingy asliirhplate under base 43 should it be desired to increase the inclination of ramp 26.V AThis is'rniavdepossible by pivotal connection of the front end ci? the ramp bar 37 and Vthe articulated relation which ramp 26 has with the supporting portion of the device.

Another feature incorporated in the present ramp strue-` ture resides' inthe provision of the end gauge 92`. lfthe coil is to beA depositedaccuratelymthen 'the end lo-A cation of the coil should be known.

The embodiment of the invention ai'eolo in Fig; ure's 6 to l0 inclusive consists 'of a in 1o`vfalller saddle only', the stetioiroiy saddles 'beiiig oiitfed, -sind liereir 'the movable saddle is" ope ely connected to p for po'sitioniogthe saddle for Holding' the e'orl eretto Ol' ft elvtl'llg theV` Sddl W/lljy fO movement "to: the coil.; The may' be 'connected t6 sliiiil de'i'ices 1n tandem relation,v

as shown in Figure 6, so that a plurality of coils may be lstored and rolled into position as they are used up in the reel. Figures 9 and y10 illustrate in detail the construction of the supporting base and movable saddle for each device and reference will now be made to said figures.

The base plate 110 is provided with a plurality of transversely extending plates including a rear plate 111, intermediate plates 112, 113 and a front plate 114. The rear plate 111 and intermediate plate 112 are joined by longitudinally extending end plates 115, 116 and by longitudinally extending intermediate plates 117, 118, the latter being of less height than the end plates since they support the journalling brackets 120.- Said rear plate 111 and intermediate plate 112 are suitably welded to the base 110 and to the longitudinally extending plates 115, 116, 117 and 118, thereby forming a strong unitary assembly.

' Additional longitudinal plates such as 121 connect the intermediate plates 112, 113 and the base structure is substantially completed by still further longitudinally extending plates 122 and 123 comprising end members and intermediate members in the form of plates 124 and 125. The front plate 114 and intermediate plate 113 are connected into a strong unitary assembly with each other and with the base plate by plates 122, 123, 124 and 125 which are suitably welded thereto. Whereas the structure of plates 112 and 118 provides for supporting the hydraulic pressure cylinder on the base, the said assembly of plates 113 and 125 provides structure which pivotally supports the movable saddle.

The movable saddle is likewise formed of an assemblage of plates which comprise a unitary structure adapted to have pivotal movement as heretofore explained for supporting the coil in a stationary manner and for irnparting rolling action to the coil when the movable saddle is elevated. The coil supporting surface of the saddle is formed by three transversely extending plates, namely, 126, 127 and 128. The plates 127 and 128 are welded to each other in a manner to form a shallow V or similar shaped depression. When plate 126 is horizontal the depression in the movable saddle is so disposed as to support a coil of metal stock in a stationary manner. However, when plate 126 of the saddle is elevated the relation of the depression with respect to the pivot axis of the movable saddle is such as to transmit a distinct forward velocity to the coil and thereby starting the coil in motion suicient to cause movement oft of the saddle onto a ramp or the like whereby the coil is delivered to the reel.

Referring again to the plates which make up the reel supporting surface of the movable saddle, it will be seen that the V or the inverted apex of the triangle formed by plates 127 and 128 is located below the level of plate 126 when the latter is horizontal. It will also be observed that the front end of plate 128 is raised or elevated apconsiderable distance whereby to eiect the proper disposition of the depression for stationarily supporting the coil." Also the depression is displaced with respect to the pivot axis some distance to the left and upon rocking the movable saddle clockwise to locate plate 12S in a horizontal position the action is such as toimpart forward momentum to the coil, thus etecting the desired rolling movement ofthe same.

. The coil supporting plates 126, 127 and 128 are welded to depending longitudinal plates 130, 131 and 132 which extend from the left hand end of the movable saddle to the right .hand end and have a shape in side elevation, as best shownin Figure l0. Additional transverse plates 133, 134 and 135 are securedlthereto .in order to form a strong unitary assembly `constituting the movable saddle. Plates 133 have lsuitably welded. thereto the stop plate 136 which is adapted to contact plate 112 to horizontally position'plate 126.v Transverse plate 134 is provided with a pair of lugs 137 suitably secured in spaced relation on the front surface of the plate and which threadedly retain the adjusting screws 138, providing stop members in contact with a rear plate such "as 111 for horizontally positioning plate 128 of the movable saddle.

The movable saddle is pivotally supported on the base structure by the pivot shaft 140 which extends through hub portions 141 and through sleeves 142. The hub portions are respectively secured to the depending plates 130, 131 and 132, whereas, the sleeves 142 are respectively secured to spaced plates 122, 124 and spaced plates 123, 125. The hydraulic pressure cylinder 143 is provided for rocking the movable saddle and it will be observed that the cylinder is operatively connected to the movable saddle at the rear thereof substantially centrally of plate 126. The cylinder is supported for swinging or pivotal movement by means of the brackets 120 which receive pintles 144 projecting from the respective sides of the cylinder approximately centrally of its height. Accordingly, the cylinder is supported by the longitudinal plates 117 and 118 in a manner which allows the cylinder to rock as it effects oscillating movement of the movable saddle. The piston rod 145 is pivotally connected by pin 146 to lugs 147 which depend from the underside of plate 126. The cylinder is suitably powered by pneumatic or hydraulic means whereby to extend or retract the piston rod 145 as a result of which motion the movable saddle is oscillated. With the piston rod retracted the saddle is positioned for holding the coil of metal stock stationary. However, when the power cylinder 143 is energized and the piston rod is extended to elevate plate 126, the front plate 128 is lowered into horizontal position. Thus the coil supported by the saddle will be caused to roll in a direction toward the right, Figure 6, and accordingly said coil can be rolled onto another saddle located in tandem relation therewith, as shown in Figure 6, or the coil can' be rolled onto a ramp, all in a manner as clearly explained in con-l nection with Figure 1.

The invention is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings as various other forms of the device will of course be apparent to thoseV skilled in the art without departing from the spirit of the invention or the scope of the claims.
