Application filed December 23, 1926, Serial No. 156,68 S,'and in Canada December 14, 1926.
This invention has relation to certain new and useful improvements in air supply connections for turntables and has for its primary object the provisionof connections exfi.tending vertically through the center hearing structure and along the main center beams of the turntable proper structure to the outer ends thereof for supplying air to the air engines.
The invention has for another object the provision of air supply connections of simple construction, composed of the minimum number of parts of simple arrangement and which may be readily connected with air-tight joints and which will not be affected by operation of the turntable.
WVith foregoing and other objects in view, as will appear as the description proceeds, the invention consists of novel construction, combination and arrangement of cooperating elements ashereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application. r
In the drawings- Figure 1 is a fragmentary top plan View of a turntable with the improved air supply connections incorporated therein.
Figure 2 is a sectional side elevation of the turntable center.
Figure 3 is an elevation of the turntable center taken at right angles to Figure 2;.
Figure 4: is a horizontal section through the turntable center structure substantially on the planeof lineIV-JV of Figure 2.
Figure 5 is an enlarged detail View of the joint formed between the cross pipes and the vertical pipe of the air supply connections, at the center of'the turntable.
Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, it is to be noted that the air supply pipe 11 from the air compresser or other source of supply, as shown may be ex tended in the bed or base of the turntable pit, below the surface, as shown in Figure 1. and one end portion 11 offset upwardly, above the bed and extended into one side of the bottom casting or base member12 of the center bearing structure to conduct the compressed air to the central air chamber 13 of the stationary bottom casting or base member 12, which, as shown in the drawings, is mounted on the raised central por tion 14 of. the bed or base and which central portion 1 1 is preferably of concrete, cement or the like. 7 p
The rotatable upper center bearing mamher or casting 15 working on'bea'ring plates 15 mounted on the lower center bearing or base member. 12 has a central vertical air passage 16 through which extends the upstanding or vertical air conducting pipe 17. The lower extremity of the pipe 17 is threaded or otherwise secured, as at 18*, in an upstanding central sleeve 18 of the lower center bearing member or casting 12 so as to permit compressed air to enter the pipe 17 from the central air chamber 13.
The pipe 17 also extends upwardly through the horizontally removable spacing I member 19 resting on the upper center bearing member 15 and then continues upwardly through the frame bearing 20 carried by the cross girders or supporting plates- 21 arranged between the center of the main center beams .22 of the turntable proper structure. I I p The upper extremity of the pipe 17 is connected by an appropriate coupling 23 with the stub extension pipe 24. An annu lar flange or bushing 25 of metal, leather or other composition is provided on the stub extensionpipe 24, within theenlarged upper portion of the bore 26 extending through the casting 27 positioned over the upper end of the stub extension pipe 24. The shoulder 28 is provided in the bore 26, below the annular flange or bushing 25, owing to the enlargement or increased diameter of the upper portion of the bore 26. It may also be stated at this time that the annular flange or bushing 25 may be integral with or formed separate from the stub extension pipe 24.- and is loose enough in the casting 27 to permit turning of the latter around the stub extension pipe 24, although preventing escape of air passing the annular flange or bushing 25. The outwardly directed annular flange 29 at the bottom of the casting 27 may be firmly fastened to the rotatable turntable structure proper by belts or other means extended through the openings 30 of the flange 29, as will be clearly understood from the drawings.
Threaded in the upper end of the casting 27 is the depending stem 31 of the T-connection 32, from the opposite arms of which extend the cross pipes 38. Extended in oppo site directions from the cross pipes 33 are the compressed air conducting pipes 34. The compressed air conducting pipes 34; extend along opposite sides of the main transverse center beams of the turntable proper structure preferably below the track rails 35, as shown in Figures 1 and 2. At their outer ends 36, the pipes 34 are suitably turned and connected with the air engines or hoists 37 on the platform 38 of the turntable structure proper to supply air to the hoists 37. Appropriate control valves 39 are provided in the turned ends 36 of the pipes 34, as shown in Figure 1.
It is believed the complete construction and operation of the parts of the present invention may now be clearly apparent from the foregoing paragraphs taken in connection with the accompanying drawings without further detail description. It may be briefly stated, however, that the turntable proper may be readily rotated on the center bearing structure without danger of breaking connections between the cross pipes 33 and the stub extension pipe 24 of the vertical compressed air conducting pipe 17, owing to the casting 27 being permitted to rotate around the stub extension pipe '24 with the platform of the turntable proper structure. Furthermore, danger of the air escaping is eifectively prevented by the annular flange or bushing 25, as previously described in detail. The vertical air conducting pipe 17 may be removed and replaced when disconnected from the stub extension pipe 24. by operation of the coupling 23, without disturbing the other parts or sections of the air conducting line.
While the preferred embodiment of the invention has been disclosed, it is to be understood that minor changes in the details of construction, combination and arrangement of cooperating elements may be resorted to within the scope of what is claimed without departing from the spirit of the invention.
' I claim:
Air supply connections for turntables including the combination with a hollow stationary center bearing member and the turntable proper structure, of an air supply pipe extended into said hollow stationary center bearing member to supply air thereto, a stattionary vertical air conducting pipe leading) from said hollow stationary center bearing member and extending upwardly into the turntable proper structure, said vertical air conducting pipe being composed of two sections detachably connected together, a hollow coupling casting surrounding the upper end of said vertical air conducting pipe, a sealing bushing surrounding the upper end of said pipe and mounted in said casting to form a rotary sealed joint therewith, a T-connection threaded in said hollow coupling casting and communicating with the upper end of said vertical air conducting pipe, cross pipes connectedto said T-connection and mounted in the turntable proper structure to rotate therewith, and air conducting pipes connected with said cross pipes and extending along the main center beams of the turntable proper structure toward the opposite'ends thereof to supply air to the air engines or hoists for the turntable.
In testimony whereof, I have hereunto signed my name.
