H. 1 scHRECK TRAVELING TILTING TABLE Filed March 27, 1950 5 Sheets-Sheet 5 to the raising and lowering of the' table, thereis provided a pneumatic devicewhich will Vnow be described. -At the forward end'of the carriage- 14l upon either side of the guides 35, there aredisposed the cylinders which are adapted to receive the hollow plunger-s 51.

the clamping devices comprising collars 54 and bolts 55 to provide a fluid tight fit between-the walls of the plunger 51 and those of the cylinder 50 at the upper end thereof. Since kthe table 15 moves through an arcuatefpath when tilted, and

- the `plungers 51 move verticallyV in the cylinders 50,'

there is provided a relatively loose connection between them which comprises the shafts 56 which occup'ycthe` hollow tapered interior of the plungers 51 and restat their lower ends upon theA seat pressed air, is supplied Yto Ythe cylinders 50 by means of the ycompressor60 carriedby the carriage 14. The air isL forced into the balancing tank 61 through the conduits 62. and'from there it mayrpass to and fromthevcylir'iders 50 through the conduits` 63. ByY means jof Ysuitable valves and controls, the fluid may besupplied to' the tank 61 and cylinders 50 at the proper pressure and vented therefrom insuch manner as' to balance 'the weight of the table 15 andv they articles carried thereby so as torelieve the lifting'mechanism from undue strain.,l

The table 15l is provided with the driven. rollers 65, the reduced ends of which are mounted in the bearings 66. The rollers 65 areA operatively connected by means of the bevel gears contained in housings 67 to the longitudinal shafting 68.V This shafting, 68 is drivenby means of Vthe motor 69 throughthe gearing encased in the housing 70. The motor 69 andgearing 70 are carried b y a lateral extension 71 ofthe 'rear endof thetable `515". "A platform or run-way 72 may be provided above the shafting 68, as illustratedA in Figures 4 "and 5. The bearingsfor the rollers65 are carried by the side frames 75 and 76,*which are f r"mounted on the beamsf44. Above the level of the rollers 65', the Yside frame 75 is provided'with the guide or guard 77 and the opposite side frame v76y adjustably and Mresiliently carries Ythe v'movable `side ,guide or guard 78. Atfintervals the side frames 76 are provided with upstanding enf-j larged portions `v80 which alternatewith the roller bearings 66; At correspondingintervals there is rigidlysecured to the side guard 78 the members 8l which are adapted to be insertedfin the recess 82 in the portions 80. The members 81 'are provlded withV hollow projecting portions 8 3 which V`are adaptedA to enter the reduced recess 84 of the 'portion so. The'part a3 of the member si V.is provided with the recess 85 Iwhich is adapted to contain the coily springl 86 which bears against' the wall 87 of the portion SOand the innerwall 88 ofthe element 81 and tends'to constantly urgel i Vthe members 80 andy 81 apart. 'NA Ybolt 90 having va head`91 ece'ivedin the recess 92 of the'member 81, passes through the opening 93 in the `wall 88, through the recess or chamber 85 and through the` opening 94 inthe wall 87. Threaded upon the projecting outer ends of the bolts are the nuts 95.: These `bolts90 serve to secure the guide 78 to the ,portions 80I ofthe side .frames Suitable packing .52 is clamped between the rings 53 by means of 76 against the compression of the spring 86 and by the'propei adjustment of the nuts 95 the nor- '.mal position ofthe side guard.78 may'be determined.A It will thus be seen that the outer side guard 78 is provided with buffer or cushioning mechanism by'means of which any shocks that it might. sustain incidental to the manipulation of articles `carried by the table may be absorbed and dissipated.

yFor the purpose of shifting the billets or other articles carried by the table from side to side Vthereof and also for rotating or inverting them Vfor their proper vpresentation to the roll passes, there is provided the manipulating mechanism which will now be described. At suitable intervals the' side beams 44 of the table 15 are provided withvthe castings' 100 which extend from one of these beamsto the other. vThese castings are provided with bearings 101 and 102 which are adapted torotatably `receive the longitudinally extending rock shafts 103 and 104 respectively. Keyed to the rock shaft 103 atl suitable intervals are the collars 105 of the swinging members 'or levers 106. -The rock shaft 103 is susceptible of rotation through an arc which will permit the member 106 to' move from the solid line position to the dotted line position shown in Figure 5. These limits of movement correspond to the'rpositions designated C and A in Figure 12.y Y

The member 106 is adapted to pass through an opening inthe block 107 which is mounted for reciprocation alongthe member 106. The member or block 107 is preferably provided with the stepped portion 108. Pivotally connected to the :block 107 vas at 109 is the link 110 which is pivote'dat its opposite end to the crank arm 111 asV atv 112. Thecrank arm 111 is provided with a sleeve portion 113 which is keyed to the shaft 104. When` both the shifting member 106 and the crank arm 111-are in-their lowermost positions the various elements are'disposed as shown in .the full line Vposition in Figure 5, in which the gear 1'15vv which is adapted to mesh with the segmental gear 116 carried` by the crank 117 which is ymounted upon the frame of the table r15 for pivotal movement as at 118. The crank 117` 1s provided with a pair of spaced arms 119 which are pivoted to the connecting rod 120 as at 121.

Mounted in bearings 122 carried by the carriage 14 is 'the crank shaft 123 provided with the crank" ,portion. 124 which is vpivotally connected to the left hand end of the connecting rod 120 as seen in Figures 1 and 3. `Crank shaft 123 is driven by the motor 125 by means of the worm gear 126 and is controlled by the magnetic brake 127. The rock shaft 104 is similarly provided at its right hand end as shown in Figure 2 with the bevel segmental gear 128 which meshes with the gear 129 carried by the crankf130 which is pivoted to the frame of the table as at 131, and is provided with the arms 132 which are pivotally connectedto the'connecting rod 133 `as at 134'. A

Acrank shaft 135 is mountedvin bearings 136 carried by the carriage 14 and is'provided with the crank portion 13,7Y which is pivotally connected to the opposite vend of the connecting rod 133.

shaft 135 is Vdriven by the motor 13a through thel Y 1,928,195 worm gearing 139 and is oontroneooy Y,the *magnetic'brake 140. It will thus be seen that by meansof lthe mechanismljust described, the rock shafts 103 and 104 may be independently rotated i'n'either direction and 'at any piositiozjlofV the tilting Vtable 15. n n n In'Figure-IZ, lettersA and B indicateV the limits of movement of the shifting member 106 between whichA the kick-up member 107 can-operata numeral ,150. In,` Figure the "manipulator -is` shown in its lowermost retracted position.- Figure Figures 6, 7 and 8 illustrate some of theV move-V ments of the shiftingmember 106 and the kickup member 107 `when handlinga piece of flat work, such as a slab or plate, indicated bythe 'l -illustrates the use of theshifter member'106 alone for raising the-slab 150 from the position shown in Figure 6 toone in which it is resting upon its edge.

` 160'. In'Flgure 9, the shifter member 106 has y been used alone to move the billet 160 laterally of the table V15 against the side guard '18. -In- Figure 10,l theshifter member 106 occupies the -sameposition" as in Figure 9, but the kick-,up .v

member' 10'?` isshown `extended and inthe act of rotating chenille; 16o about itsiongitudinm axis through contact with the corner and sides of the billetby the lstepped portion 108 of the member 107. Figure 11 showsjthe shifter member 106 in an intermediate position and the kick-up" member 10'? still further extended along' the member 106 Awith the corner edge ofthe billet engaged `by thelowermost ledge of `the'stepped portion los.4 n Although but a few rof the possible positions and Vuses to which the manipulator mechanismv can be put have beenillustra'ted, many other functions and combinations of uses of the two article` engaging' members 106f`a'nd 107 will occur to persons skilled in the art; f -v Furthermore, it willbe apparent that various changes and modincations canr be made in" the embodiment illustratedV without departing from the scope ofthe invention as denned in the sub-Vv joinedV claims. i
