TURNTABLE.
All known turntables with subdivided main girders, the parts of which are connected together by elastic or flexible members have a great disadvantage compared to turntables where the main girder parts are connected together by joints (articulations) because the taking apart of the turntable for repairs or for getting at the cen-' tral bearing is rather di'flicult due to the fact that the elastic members or lamels are riveted for the sake of safety.
The object of my invention therefore is to develop the so-called spring joint in such a way as to make it easily possible to disengage its connection with the girders when the turntable has to be taken apart, without injuring the safety of the connection as long as the turntable is in function. Thus also replacing of damaged spring joints in a very short time becomes also possible.
The invention can be understood from the annexed drawings.
Fig. 1 showsrthe elevation of the turntable, with a main girder divided in its middle part, i. e., near the central bearing; the main girder parts are connected together by spring joints to girders placed upon the central bearing; Fig. 2 shows a transverse section through the centre of the turntable at a largerscale; Fig. 3 shows a side View of the central bearing and of the connectionof one of the main girder parts with the girders placed on the bearing; Fig. 4 shows a view of the spring joint; Fig. 5 shows a top View of the spring joint; Fig. 6 shows another form of execution of a spring joint and Fig. 7 shows a further form of the spring joint.
. From Fig. 1 it can be understood that'the main girders of the turntable supporting.
the rails consist each of two parts which are connected by spring joints to cross girders placed on the central bearing 4 in a manner as will be described later. 7
At first I will describethe modefo'i" execution of my invention according to Figures 2, 3, 4 and 5.
On the revolving plate?) of the bearing 4 'two U shaped cross or transverse girders 5, 6 are fixed ina certain distance one from the other. Upon the upper flanges of the cross girders 5, 6, on both sides of each of the main girders, two U iron pieces 7, 8 are placed, bridging the space between he Application filed July 19,1926, Serial No. 123,428, and in Austria July 21, 1925.
Between each of the two U iron pieces 9, lO'the upper end of a flexible lamel 11 is fixed, on the lower end of which a plate 13 provided with a shoulder 12 is attached. The lamels 11 which thus are supported by the cross girders 5 and 6 through the U irons 7 and 8 pass downward through the space between the two cross girders 5, 6. As such lamels are placed on both sides of the main girder parts, there are actually four such lamels 11 near the position of joints of the two main girder parts 1 which are in alignment. On the shoulder 12 of the plates 13 of two lamels 11 situated in the same cross plane, U irons 14 are placed and fixed to the thinner parts of these plates 13 in such a way that they bridge over the space between the lamels of the same cross plane and their upper flanges :t'orm supports for the ends of the main girder parts 1 lying upon them. In .order to provide for a suflicient passage for the cross girders 5 and 6, the end of the main girder parts 1 has a recess 15 (see Fig. The second pair 01 lamels 11 in the same alignment, serves to support the adjoining main girder parts and the same is provided for the other main girder parts on the other side of the longitudinal section through the center.
Thus the end ofeach main girder part 1 is hanging on two lamels 11, placed on both sides of the main girders, these girder parts resting freely on the upper flanges of the U irons 14 or being attached to them by screws or other easily disengageable means. The U irons 7 and 8 are connected to the upper flanges of the cross girders 5 and 6 by fixing means allowing of easy disengagement, such as screws or ciamps, whilst the connec tions of the U irons 9 and 10 to the U irons 7 and 8 and the lamels 11 between the two U irons 9 and 10, and finally the plates 13 to the laniels 11 can be effected by riveting because no disengaging of these parts is ever necessary. Eventually the U irons 14 can what after their connection to the U irons 14- from the main girder part has been un done; afterwards the U irons 7 and 8 have to be disconnected from the cross girders and 6, further the U irons 14 have to be removed and the U irons 7, 8, 9 and 10 together with lamels 11 fixed on them have to be completely drawn upwards and re moved. If the lamels are taken away and the cross girders 5 and 6 are removed, it is possible to lift plate 3 from the center hearing 4%. The reassembling of the turntable is just as simple and it is evident that now it is quite possible to replace damaged spring joints, i. e. the lamels with all parts fixed on them.
A U iron 33 is fixed with its two ends to the two aligned main girder parts, a flat iron piece 34 being placed under each end of the said U iron 33 (not shown in Fig. and this U iron connects the main girder parts in such a manner as to maintain their movability secured by their hanging on the lamels 11 because these U irons have only a small moment of resistance in a vertical di rection and therefore only the necessary stiffness of the main girder connections in a horizontal direction is secured. The outer lamels 11 pass through openings in the U irons 33.
Fig. 6 shows another modeof execution of the spring joints in which instead of the two cross girders 5 and 6 of the construction as first described, two pairs of crossgirders 16, 17 are placed on a bearing plate 18 and in which each of the lamels 19, 20 of the same cross plane passes through the space between the girder pairs 16, 1"; the lamels are supported by the upper flanges oi? the girders 16, 17 by means of girder pieces 21, 22 attached to their upper ends. The remaining parts of the construction may be the same as described above.
Fig. 7 shows a mode of execution in which again only two cross girders 25 are fixed upon the bearing plate 26 at a greater distance from each other and the two lamels 27, 28 placed one behind the other are fixed at a small distance from each other on the girder pieces 30, by placing between them a piece of fiat iron 29, these girder pieces 30 bridging the two cross girders 25. On the lower end of each lamel a U or angle iron 32 is fixed serving as a seat for the supporting girders 31. The flat iron 29 distancing the two lamels 27, 28 allows of the necessary movability of the lamels.
The distance of the cross girders 25 from each other is so great as to make it possible to draw out easily the lamels without necessitating the taking ofi? the girder pieces 32.
Instead of simple lamels it is of course possible to use piles of such lamels.
The construction of the supports on the upper and lower end of the lamels may be varied in manifold ways.
What I claim as my invention is:
1. In a turn-table having subdivided main girders, the combination of a central bearing having a rotating plate, cross girders fixed to said rotatable plate, girder pieces removably supported by said cross girders, flexible lamels fixed with their upper ends to said girder pieces, and supporting pieces fixed to the lower ends of said lamels, each oi. said supporting pieces serving as a support for one of the ends of the main girder parts to be joined, said lamels together with said girder and supporting pieces being removable as a whole when the turntable is dismounted.
2. In a turn-table having subdivided main girders, the combination of a central bearing, supporting girders carried by said bearing, flexible lamels, means for removably suspending the upper ends of said lamels on said supporting girders, and means on the lower ends of said lamels for removably fixing one end of one of said main girder parts to be joined, said lamels be ing removable when the turn-table is dismounted.
3. In a turn-table as set forth in claim 1, two cross girders supported by the rotatable plate of the central bearing, said two cross girders being at such a distance from each other so as to allow the lamels together with their lower supporting pieces to be withdrawn upwards through the space between said two cross girders.
1. In a turn-table as set forth in claim 1, two lamels arranged on each side of the end portions of the main girders, and a supporting piece for each of said main girders, said supporting piece being carried by the two lamels arranged on both sides of each of said main girders.
5. In a turn-table as set forth in claim 1, two lamels arranged one behind the other in a direction parallel to the main girders, pieces of girders removably supported by the cross girders carried by the central bearing, other pieces or girders fixed to said first named pieces of girders, said lamels being fixed to said second named pieces of girders, and means fixed to the lower ends of said lamels for supporting the end portions of said main girders in alignment, all of said pieces of girders together with said lamels and said supporting means forming a combined piece adapted to be removed as a whole from said cross girders when the turn-table is dismounted.
