United States Patent BLOOM TURNING APPARATUS Frederick H. Evans, Massillon, Ohio, assignor to Evans Enterprises, Inc.,Massillon,'0l1io, a corporation of Ohio Application October 15, 1953, Serial No. 386,337

15 Claims. (Cl. 214--1) The invention. relates to apparatus for handling blooms and the'like, and more particularly to apparatus for turning a bloom or similar article so as to successively present eachof its faces to afford inspection and scarfing.

In usual steel mill operation an ingot which may weigh as much as two or three tons is first rolled on a blooming vmill to form a single bloom, or several blooms, usually rectangular in cross section. After being thus rolled or hammered, such blooms must be inspected, and any slag or scrap adhering thereto, or other imperfections must be removed, as by scarfing, chipping or grinding.

For this purpose it is necessary that the bloom be turned so as to successively present each of its longitudinal faces Under present steel mill practice no adequate apparatus is provided for such turning of blooms, and owing to the extreme weight of the blooms, this is a slow, laborious and often dangerous operation.

It is an object of the invention to provide means for easily and quickly turning a bloom in a manner to suecessively present its longitudinal faces for inspection and, cleaning or scarfing, so as to overcome the above-mentioned disadvantages and objections.

Another object is to provide a mechanical apparatus upon which blooms may be placed by a lifttruck, crane or other lifting means, and which may be easily operated to intermittently rotate each bloom upon its axis so as to successively present each of its longitudinal faces in position for inspection or cleaning.

A further object'is to provide a bloom turning apparatus comprising side rails having notches therein for receiving a bloom and holding it with a longitudinal surface presented for inspection or cleaning, lifting levers for.

moving a bloom along said rails and depositing it in said notches and lever operated lifting jaws for lifting .the bloom out of said notches and turning it axially to present another longitudinal face thereof, means being provided for repeating this operation until each longitudinal face of the bloom has been presented for inspection or cleanmg.

A still further object of the invention is to provide a bloom turning apparatus of the character referred to in which two or more blooms may be simultaneously picked up by the lifting levers, automatically repositioned upon said levers, and simultaneously rotatedupon their axes so as to successively present the different faces of both blooms.

Another object is to provide such a bloom turning apparatus in which auxiliary blocks may be detachably mounted upon the rails and upon the turning jaws to adapt the apparatus for handling and simultaneously turning two or more blooms or the like.

A further object is to provide a bloom turning apparatus of this 'type in which the lifting levers and the turning jaw levers are both attached to a main shaft which is oscillated by driving means such as fluid cylinders, whereby the movements of the lifting levers and turning jaws are coordinated.

ings and following description, may be attained,the-above described difficulties overcome and the advantages and results obtained, by the apparatus, construction, arrangement and combinations, sub-combinations and parts which comprise the present invention, a preferred embodiment of which, illustrative of the best mode in which-applicant has contemplated applying the principle,'being set forthiin detail in the following description and illustrated in the-accompanying drawings, in which;

Fig. 1 is a top plan view of a bloom turning apparatus embodying" the invention, the parts being shown. in the initial position;

Fig. 2 is a side elevation of the machine with the-auxiliary blocks thereon adapting the machine to simultaneously handle two blooms of small cross section showing the lifting levers moved to position to engage theleading bloom in the first notch of the side rails;

Fig. 3 a section as on the line 3-3, Fig. 1, showingthe lifting levers moved backward from the position. of Fig. 2, with the two blooms repositioned for further movement through the machine; a

Fig. 4 is a side elevation of the apparatusas shown in Figs. 2 and 3 with the two blooms positioned' upon-tthe side rails for inspection or scarfing of one longitudinal face of each bloom;

Fig. 5 is a section similar to Fig. 3 showing the manner in which the two blooms are picked up by the turning jaws for turning movement of the blooms; and,

Fig. 6 is a fragmentary section similar to Figs. 3 and, 5 with the auxiliary blocks removed showing-the manner in which a single large cross section bloom is turned in,-tl1e machine.

In general terms the apparatus comprises a spacedpair of arcuate rails having notches for receiving blooms to hold them in position to present one face thereof for inspection and cleaning; spaced supports at one end of'the rails for receiving blooms from a lift truck, crane or the like and supporting them in position to be picked up by .a pair of lifting levers mounted upon the main shaft ofthe machine and located on the outer sides of the rails and having arcuate flanges thereon; turning jaws pivotallyconnected to levers fixed uponthe main shaft and also-pivotally connected to levers fixed upon countershafts; drive means, such as fluid cylinders, being operatively connected to the main shaft to oscillate the same, whereby the lifting levers will pick up blooms from the spaced supports and move them along the rails and position them in'the notches in the rails, presenting one longitudinal faceof each bloom for inspection or cleaning, and the turning jaws will pick up the blooms and turn them topresent one face after the other for inspection or cleaning. Platforms of suitable height may be located at the opposite. end of the rails for accommodating workmen to inspector scarf the blooms.

Referring now more particularly to the embodiment. of the invention illustrated in which similar numerals refer to simliar parts throughout, a base frame, indicated generally at 10, is adapted to support the apparatus upon a floor or the like, and mounted thereon is a spaced pair of similar rail members 11 each having an arcuate-e'dge 12 extending from the charging end of the rails and terminating in a deep angular notch 13 at the opposite end thereof.

A slight angular notch 14 is preferably provided in the periphery of each rail 11 just ahead of the notch 13 therein. In cases where it is desirable to adaptthe apparatus for simultaneous turning and handling of two. or more small cross-section blooms or billets at a time, an. additional angular notch 15 may be formed in the periphery of each rail, ahead of the notch 14, for the purpose of assisting in repositioning the blooms or billets as will be later described in detail.

These notches are not absolutely necessary, and while they are desirable to make the repositioning of the blooms or billets a positive operation, the repositioning could be accomplished without these notches.

A spaced pair of supports 16, longitudinally aligned with the rails 11, are located adjacent to the rails at the entrance side of the apparatus. Each of these supports may comprise a pair of vertical plates 17, bolted or otherwise normally rigidly attached to the adjacent end portions of the rails 11 as indicated at 13. By removing certain of the bolts these supports may be swung upward when it is desired to move the machine by truck or otherwise, whereby it may be readily transported.

Elongated, longitudinally disposed plates 19 and 2b are preferably welded or otherwise secured to the upper and lower edges respectively of the plates 17, forming spaced supports upon which blooms or billets may be placed by means of a lift truck, crane or the like.

A main shaft 21 is journalled transversely through the rails 11, and for this purpose each plate or rail 11 may have a substantially central aperture 22 formed therein to receive a bearing bracket plate 23 which may be provided with depending flanges 24 for reinforcing and supporting the same.

These bracket plates may be welded or otherwise secured within the opening 22 and upon each bracket plate is mounted a bearing 25 attached to the corresponding plate 23 as by bolts 26. Transversely disposed ribs 27 may be welded or otherwise integrally mounted upon each plate 23 for engagement with each side of the corresponding bearing 25 to rigidly position the bearings upon the bracket plates 23.

The main shaft 21 is journalled through the bearings 25 and opposite ends thereof extend outwardly beyond the rear plates 11. A lifting lever 29 is fixed upon each outer end portion of the main shaft 21, and each lifting lever is provided upon its forward side with a substantially triangular flange 30, the peripheral edge 31 of which is arcuate and concentric with the main shaft 21.

As best shown in Figs. 2 and 4, the peripheral edge 31 of the flange is located slightly below the peripheral edge 12 of the corresponding side rail 11. An operating lever 32 is keyed or otherwise rigidly mounted upon each outer end portion of the drive shaft 21 adjacent to the corresponding lifting lever 29.

For the purpose of operating the lifting levers 29 in unison, fluid cylinders 33 are provided, each cylinder being pivotally mounted, as indicated at 34, upon a bracket 35 mounted as by angle irons 36 upon the spaced

vertical walls

37 and 38 of the housing in which each cylinder is located. The piston rod 39 of each cylinder is pivotally connected as at 40 to the end portion of the corresponding operating lever 32.

The cylinders 33 are double acting cylinders and are operatively C(l.l.Cld in conventional manner by suitable hose or the like (not shown) with a fluid pump as indicated at 41 operated as by motor 42 and provided with reserve tank 43 all as in usual and well known manner, The motor, pump and tank may be mounted upon a suitable bracket, indicated generally at 44, supported at the rear side of the machine.

A pair of turning jaws, generally indicated at 45, is provided for turning the blooms or billets axially to present different longitudinal surfaces for inspection and cleaning. Each turning jaw has an angular notch 46 in its upper edge which, as shown in the drawings, may be slightly greater than 90 degrees.

A depending lug 47 is formed at the forward edge of each turning jaw for pivotal connection, as indicated at 48, with the corresponding turning jaw operating lever 49 which is keyed or otherwise fixed upon the main shaft 21, inwardly from the corresponding side rail 11.

For the purpose of causing each turning jaw to move through the proper path, a link 50 is provided being located parallel to the operating lever 49, one end thereof being pivotally connected to the rear lower corner of the turning jaw, as indicated at 51, the other end thereof being mounted upon a countershaft 52 journalled in a bearing 53 mounted upon a bracket 54 as by bolts 55, each bracket 54 being rigidly connected to the inner side of the adjacent side rail 11.

Transversely disposed, spaced,

vertical frame members

56 and 57 are located at the rear side of the machine and provided with vertically spaced

angle irons

58 and 59 fixed upon the

frame members

56 and 57 at two different heights for supporting a platform 60 in either the full line or dotted line position as shown in Fig. 2, so that an inspector or workman may stand thereon, as will be later described.

In order to adapt the apparatus for handling and turning two or more .naller cross-sectional blooms or billets simultaneously, removable blocks 61 may be detachably mounted in the angular notches 13 of the side rails. For the purpose of easily and readily mounting the blocks 61 or removing them from the side rails, the lower portion of each block is longitudinally grooved, forming a pair of bifurcations 62 adapted to straddle the side plate, and a pin 63 is located through suitable apertures in said bifurcations and in the side plate. Similar blocks 64 are adapted to be removably mounted in the angular notch 46 of the turning jaws 45 as by pins 65.

Thus the blocks 61 divide each of the angular notches 13 in the rails into two smaller angular notches each of which is adapted to receive one smaller cross-section bloom positioned with one longitudinal face thereof presented upward for inspection or scarfing.

in the same manner each block 64 divides each angular notch 46 in the turning jaws 45 into two smaller angular notches, each of which is adapted to pick up one bloom from the notches in the rails and to cause the bloom to turn upon its axis as it is again deposited in the notches of the rails, with another longitudinal face thereof presented upward.

In the operation of the apparatus, to turn a pair of blooms or billets simultaneously, with the

blocks

51 and 64 mounted upon the side rails and turning jaws respectively, the cylinders 33 are operated to position the lifting levers 29 substantially horizontally, below the top surfaces of the spaced supports 16, as indicated in Fig. l, and in dot and dash lines in Fig. 2.

A pair of blooms or billets B, as indicated in dot and dash lines in Figs. 1 and 2, are then deposited side by side upon the spaced supports 16. The cylinders 33 are then operated to move the lifting arms upward and forward, or in a clockwise direction, as viewed in the drawings, to the position shown in full lines in Fig. 2, at which time the foremost bloom or billet, which has now become the lowermost, is received in the angular notches 15 in the side rails 11, as shown in full lines in Fig. 2.

The cylinders 33 are then operated to move the lifting levers 29 backward, or counterclockwise, as viewed in the drawings, the foremost or lowermost bloom or billet remaining stationary in the notches 15 of the rails, while the other bloom or billet is permitted to drop behind the same onto the peripheral portion 12 of the rails.

The two blooms or billets are thus positioned upon the rails, one behind the other instead of one on top of the other, as shown in Fig. 2. This is desirable in order to prevent the uppermost billet from dropping two great a distance when they are moved into their final position, as will be later described.

The cylinders 33 are again operated to move the lifting levers 29 forwardly, or in a clockwise direction as viewed in the drawings, through the position shown in Fig. 3 to the final position, as shown in Fig. 4, when both blooms or billets are positioned, as shown in Fig. 4, the foremost bloom or billet being located upon the bottom edge of the angular notch 13 and against the 'uforwardzedge of the block :61, while therearmost billet 551s. locatedupon the top of the block 61 and against the 11631" edge ofthe notch 13.

Both billets'are thus located in position so that the irons 59.

In order to turn the blooms or billets so as to present I -:the next longitudinal face of each for inspection or cleanng, the cylinders 33. are operated tomove the lifting levers {29 backward or counterclockwise to the position shown This movement of :the main shaft 28 raises the turn- Qingjaws 45 so as to pick up the blooms or billets therein, ..-the foremost bloom or billet being located upon the bottomt-of .the angular notch 46 in front of the block 64,

.-while..the-=other bloom or billet is located on top of the .block 64 andagainst the rear edge of the angular notch 46.

This backward movement is continued until the rear v.lower corners of the two-blooms are located over the ]upper cornersof the blocks 61 and into the notches 14 respectively, as indicated in Fig. 5. It will be seen' .that .the movement of the machine slides the blooms or billets up the incline of the turning jaws, breaking loose .any slag or scale that might impede the blooms or :billets from positioning themselves for turning.

. Forward or clockwise movement of the levers 29 will .thencause the blooms or billets to turn a quarter turn .inthe. direction of the arrows shown in Fig. 5 and drop .'backintothe.positions shown in Fig 4, with another lon- 'gitudinalfaceof each presented upward. This operation .is repeated until. each of the four longitudinal faces ,of each bloom or billet has been presented for inspection or scarfing, as the case may be.

-'For turning blooms or billets of larger cross. sectional size, the blocks .61 and 64 are removed from the rails "11 and turning jaws 45 respectively, anda single, large "cross section bloom or billet as indicated at B in Fig. 6'is adapted to be handled and turned in the apparatus.

'The operation is similar to that above described, the

bloom' first being deposited upon the spaced supports 16 at the charging end of the machine, the lifting lever 29 being located in the dot and dash line position of Fig. 2 so that they are below the bloom.

"The cylinders are then operated to move the lifting leversl29' upward, or in a clockwisedirection, moving the bloom B .over the edges of the rails 11, as above described with reference to Figs. 1 to- 5. The notchesin the rails do not perform any function in this operation however, and the lifting levers 29 continue to move forward until the single bloom B is deposited in the notches 13 of the rails.

The arcuate edges 31 of the flanges 30 upon the lifting levers 29 comeflinto play at this point, as they receive the bloom as it starts to drop into the, notch 13, preventing tl e heavy bloom from dropping the entire distance at one time.

The lifting levers 29 are then moved backward or counterclockwise, moving the peripheral edges 31 of the flanges 3.0 'out from under the bloom and permitting it to drop into the notches 13 of the rails in the position shown in broken lines in Fig. 6,

presenting one longitu dinal face thereof upward.

In order to turn the bloom so as to present different "longitudinal faces thereof for inspection or cleaning, the cylinders 33 are operated to move the turning jaws in a counterclockwise direction, lifting the bloom -B but of thenotches 13 in the rails and positioning the lower rear cornerthereof upon the rails adjacent to the notches 13, in the position shown in full lines in Fig. 6.

As the cylinders 33 are then operated to move the turning jaws'45 forwardly, or in a clockwise direction,

'the-bloomB will-be turned'upon'its axis and drop into the hatches"- 13 of the rails with "thenext adjacent longitudinal face presented 'upward 'forcleaning or scarfing. This operation is continued until all four longitudinal faces of :the bloom have been turned upward so that they may be inspected or cleaned, as the case maybe.

be removed from the notches in the rails by a crane, or other conventional lift mechanism, and the machine is ready for receivingand turning another bloom or blooms,

as the case may be.

From the aboveit will be-obvious that a simple, etncient and readily operated machine is provided for quickly and easily handling blooms, billets-andthe like and turning the same upon their axes was to successively present each longitudinal face thereof for inspection or cleaning.
