AUTOMATIC-OPERATING AIR-COM PRESSOR.
SPECIFICATION forming part of Letters Patent No. 639,539, dated December 19, 1899. Application fllecl November 1, 1898. SerialNo. 695,148. (No model.)
To all whom, it may concern:
Be it known that I, GEORGE E. DRUM, acitizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Automatic-Operating Air-Compressors, of which the following is a specification.
My invention relates to improvements in air-compressors that are operated by steam or other power; and it consists in the combination of a pulley and belt driven air-pump, a piston-actuated belt-shifter, a two-way airvalve, and a pressure controlled and actuated lever for moving the air-Valve, admitting to and discharging air from a piston-cylinder, shifting a belt from a tight to a loose pulley, stopping the air-pump when a given pressure has accumulated, and starting the air-pump when the pressure has fallen below a set pressure. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a front elevation of an automatic air-compressor constructed according to my invention. Fig. 2 is a top View of the beltshifter and parts for operating the same. Fig. 3 is an end view of the two-way air-valve. Fig. at is a section taken on the line X Y of Fig. 3.
Similar numerals of reference refer to the same parts in all the figures.
1 represents the driving-belt; 2, the driving-pulley; 3, the loose pulley, and 4 the airpump. This air-pump is single-acting and is provided with an inlet and a discharge check-valve placed in the bottom of the cylinder.
5 is the pipe for carrying the compressed air from the pump to the reservoir.
6 is a branch pipe carrying air to the twoway valve. I
7 is a branch pipe carrying air-pressure to the diaphragm-regulator.
Sis the regulator-lever; 8, the adjustable weight; 9, the connecting-rod connecting the lever 8 to arm 10 on valve-spindle 16.
11 is the two-way valve; 12, the piston-cylinder; 13, the weighted arm; 13, the adjustable weight; 14, the connecting-rod connectand 18.
ing the bell-crank arm of lever 13 to the beltshifter 15. The two-way valve is clearly and plainly shown in the enlarged Fgs. 3 and 4'.
11 represents the body of the valve and is constructed with two ports 17 and 18.
16 is a spindle-valve provided with a collar 19. This collar is provided with ports 17 (See Figs. 3 and 4.)
The operation of my invention is as follows: The weight 8 is adjusted on lever 8 so as to rise at, say, a pressnre'of one hundred pounds to the square inch, at which pressure the lever 8 will rise and through the rod 9 raise arm 10 and rotate the spindle 16, so as to open the air-port 1S and close the port 17. This will admit air into the piston-cylinder 12. This air forces the piston against lever 13, raises it, and it in turn, through the con nection 14., moves the belt shifter 15 and shifts the belt 1 from the tight pulley 2 to the loose pulley 3 and stops the air-pum p. When the pressure has fallen below one hundred pounds, the lever 8 falls, rotates the spindlevalve back, closes port 18, and opens port 17. This allows the air to escape from under the piston in the cylinder 12, and the weight 13 is so set that it will shift the belt 1 to the pulley 2, as shown in Fig. 1, and start the pump and accumulate the desired pressure, when it will .be automatically stopped, as before described. If it be desired to use the pressure to start the pump, 3 will be the driven pulley and 2 the loose pulley.
Having, as above, fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-- The combination with a belt and pulley driven air-pump, abelt-shifter, a weight applied thereto, tending to shift the belt to the loose pulley, a piston acting to lift the weight, a two-way valve controlling the admission and exhaust of the pump-pressure to and from the piston and a diaphragm connection controlling the valve, the diaphragm being exposed to the pump-pressure, all substantially as shown and described.
GEORGE E. DRUM.
