a' citizen of the United States, residing at Latrobe, in the county of Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Compressors, of which/the following is a specification.
The invention relatesto animproveinent in compressors and particularly to a means for operating ya series of compressors in an even an uniform manner.
'Ilie/ main object of the present invention is the provision of a compressor operating device including a rotating element having cam and pin connection with the piston 4stem oa pln'ralityof compressors, the construccomiection to vary the stro ce of the piston or pistons at will. 5' y The invention in its preferred form of specification, reference being had particularly to the accompanying drawings, in whieli'- y y Figi'ire 1 isa longitudinal sectional view showing two compressors coupled tothe im# provedA operating means. Fig. 2 is an end elevationv of the saine. Fig. is a trans-' the cam vsleeve is correspondingly rotated Awith the effect to reciprocate the pistons Vwithin the cylinders for the desired-comy verse section oi the same.
In the accompanying drawings, the improved. operating means designated generally' by l is shown as ,connected to two double compressors designated-@generally by 2 whichas shown are duplicates of each other. -The compressors comprise cylinders 3 ha ving heads Ll-.und o'sets 5, whereby'7 they maybe bolted as at G to an appropriate hase" 7. Within the cylinder 3 are mounted pistbns 8 connected for simultaneous move- Mounted centrally vbetween the cylinders is a drive shaft 1,0, preferably supported in bearings. l1 rising from the base plate 7.
Centrally of the valve of the cylinders the' shaft is enlarged at 12 on which through the mediuiniof the key 13 is secured a sleeve y 14 .formed Vwith a cam channel 15 in its outer surface', the channel extending circum.y Vferentially of the sleeve, so as to present its maximum operating portion approximately 'i at the respective ends oi' the sleeve. The
` cam sleeve V14: is of such diameter as to pron ject vwithin the plane of the cylinders 3,
the latter being cut away at 16 toireceive the sleeve.
f i Slidably mounted upon each piston rod 9 is a connector 17,. comprising a .cruci- :t'orm element centrally formed with an opening 18 to slidably engage the piston rod. The connector is provided with a threaded opening 19 extending at right anglesto the opening 18 for the reception ofthe threaded stud20, the outer terminal of which projects' through a slot 21 in the cylinder 3 and is provided with a head 22 for wrench application. By means of the ystud 20 it is obvious that the connector may be locked in any desired position upon the piston. rod 9 'within the limits of the slot 21. From the connector at a point dihmetrically opposite the stud 20 there is extended a shaft 23, the
`. ee terminal of whichis( designed to fit iny the cam groove 15l of the sleeve 14, the
.terminal of' the shaft being if desired in the form of a freely rotatable roller 'to avoid friction. The connectbr'is further guided `in movement by a stud-*24 extending there- 'from at vright angles to the shaft 23'to a screw stud 20,v which stud is guided in the' slot 25 formed lin the cylinder 3.
From the above description, it will be ap-I 'l parent that in 4the rotation of the shaft 1'0 pression of theirr eiiect, It is obvious that any number of cylinders maybe operatively connectedl to the cam sleeve, the cylinders being arranged in annular series. The improved operating device insures a ysmooth noiseless operation, eliminates crank connection, and requiresicomparatively little power to drive it.
What 1s claimed is i 'In combination, a pair of cylindershaving an operating mechanism therein including piston rods, a frame connecting the cylinders together, a drive shaft positioned 1 intermediate said cylinders, said shaft having an enlargement formed thereon inter mediate the ends of the cylinders, bearings for said shaft and contacting with the ends justably mounted on said piston rods, said
