United States Patent AIR SUPPLY SYSTEM Frank K. Berry, Pacoima, Calif., assignor to General Motors Corporation, Detroit, Mich., a corporation of Delaware Application December 9, 1957, Serial No. 701,422 Claims. or. 137-322 This invention relates to power supply systems and more particularly to mechanisms by which power is supplied to a power driven tool from any of a number of power supply outlets.
Many industrial production line operations require the use of air powered tools or electric tools suspended from hoses or cables overhead. The production line conveyor moves at a constant speed and the tool must travel with the workpiece as the operation is performed. In many cases hoses or cables must be quite long in order for the particular operation to be carried out as the workpiece moves along the production line. Thus hoses and cables must be dragged back and forth along the floor, and the operator is allowed only the length of time required for the workpiece to travel the length of the hose or cable feeding his tool to carry out his particular operation.
The device in which this invention is embodied comprises a track assembly and a carriage assembly, which is movable along and within the track assembly, and carries the tool hose or cable. This allows for shorter lengths of hose or cable, keeps the hose or cable off the floor and permits completion of the particular operation past the normal operating point, if necessary, resulting in more eflicient operation and material saving in wear and tear on the hoses or cables and attachments.
In the drawings: f
Figure 1 is an elevation view of a track assembly partly in section to show the carriage assembly mounted therein, and further illustrates in phantom difiierent positions of the carriage assembly.
Figure 2 is an enlarged sectional view of the track assembly of Figure 1 showing the carriage assembly partly in section mounted therein.
Figure 2a is an enlarged sectional view of the air sup- Figure 3 is a sectional view substantially along the line 3--3 of Figure l with parts broken away.
Figure 4 is a plan view partly in section of the track assembly and carriage assembly of Figure 1.
Referring more particularly to the drawings a suspended track assembly 10 is suitably supported over an assembly line in a production installation where power tool operations are carried out at a series of stations along the line. A carriage assembly 11 mounted within the track assembly moves along the track 38 at the will of the tool operator below. A seriesof air supply outlets 12 are mounted on the track assembly and are'connected with a main airfsupply suitably located with respect to the production line. i
The carriage assembly 11, shown in more detail in Figures 2, 3 and 4, rolls on a plurality of load bearing rollers or wheels 13 which support the carriage block 14 on the axles 15. Ball bearings 16 between the rollers or wheels and the axles provide smooth travel of the carriage assembly along the track. A conduit or power transmitting means 17 extends through the carriage block and is carried by the. carriage block to operatively connect the tool hose 18 with an air supply outlet 12. The air 2,926,689 Patented Mar. 1, 1969 2 supply outlet is mounted on a casing member 39 and consists of a female outlet member 19 extending through the casing member and retained on the casing member by a nut 20. A hose 21 extending from the main air supply is attached to a pipe fitting 22 which is threaded into the female outlet member. A valve 23, inside the pipe fitting 22, operates to open or close the air supply outlet. The valve member 23 has a flange 25 mounted thereon which seats on a resilient seal 26 to block the flow of air through the female outlet member 19. A spring 24 acts between a shoulder 40 on the pipe fitting, and the flange 25 on the valve member, to bias the valve member in the closed position. The valve member has a pilot portion 27 at its lower end consisting of a plurality of lands 41 which keep the valve member from misalignment with respect to the air passage through the pipe fitting 22 and the female outlet member 19, and provide openings for a flow of air through the outlet when the flange 25 is disengaged from the seal 26.
Mounted on the upper extremity of the conduit 17 is a snap coupling 28 which fits into the female outlet member and into the resilient seal 26 of the air supply outlet 12 to provide a passage for air from the main airsupply to the tool below. The upper end of the snap coupling engages the lands 41 on the valve member to unseat the Washer from the resilient seal and open the'passage to a flow of air. Resilient means, such as a spring 29, seats against a spacer 30 mounted on the carriage block 14 and surrounding the conduit 17. The upper end of the spring 29 bears against the base flange 31 of the snap coupling to bias the snap coupling into engagement with the air supply outlet when the carriage assembly is properly positioned along the track assembly. Proper positioning is obtained through the use of a guide block 32 surrounding the lower end of the conduit 17 and retained on the conduit by a conventional retaining ring 33. The guide block carries a plurality of wheels or rollers 34 which are secured to the guide block by means of bolts 35. These rollers or wheels are adapted to engage openings 36 in rails 37 mounted below the track 38.
The track assembly comprises a track portion 38 and a casing portion 39 on which the air supply outlets 12 are mounted. The casing 39 serves to protect the air lows. Air is supplied to the air supply outlets 12 from any suitable source. At the beginning of the operation the carriage is positioned below the air supply outlet nearest the workpiece on which the tool is being used, as shown in phantom in the center of Figure 1. The rollers 34 are engaged in the openings 36 in the guide rails37 and the snap coupling 28 is engaged in' the air supply outlet 12 by the spring 29 to transmit air from the main air supply to the tool. The operation is carried out for as long a time as the length of hose will allow, at which time the operator pulls on the hose to disengage the guide block rollers 34 from the guide rail openings 36 disconnecting the snap coupling 28 from the air supply outlet 12 to allow movement of the carriage assembly 11 along the track. The operator, by pulling the hose, moves the carriage assembly, as shown in phantom at theright of Figure 1, to the next convenient air supply outlet and the guide block rollers will engage the adjacent guide rail openings. The resilient means acting beaeaaesa tween the carriage block'and the conduit will automatically engage the snap coupling in the air supply outlet to. supply power to the tool. This operation is carried out as many times as is necessary for the operation to be performed.
