To all whom lit -may concern,.-
:Be it known that I, FREDERICK VAN VDUZERv LONGACRE, a citizen of the United States, and a resident of the borou h of Manhattan, in the city and State of ew York, havei'nvented new and useful Improvements t in Unloaders for Single-Acting Compressors,
of which the following is a specification.
TheA object v`of this invention is to provide certain improvements in the construction,
`form, and arrangement of the several parts between the pressure-port of the discharge# valve andthe receiver. IFig. 2 isasimilar view showing the |positions of the parts'when the electromagnet is energized and communication is established between the pressure-port of the discharge-valve andthe exhaust-port leading to the atmosphere. Fig. 3 is a dia` grammatic view showin lan electrical system suitable for'use in contro ling the operation of the unloader-electromagnet, the said view including portions of a one stage air compressor, a receiver, the unloader, and the ipe connectionsy between 'the discharge va ves,
receiver, and unloader; and Figlfi is a-detail View in section of one ofthe disc arge-valves.y
In this type of unloader pressure is established back of the discharge-valve by openin communicationfrom the receiver to the bac of the discharge-valve, and the dischar evalve is unloaded yat any desired moment y the energiz'ation of an electromagnet whic will operate a valve and open communication l from the space back of` the discharge-valve to the atmosphere, which valve at thevsame time will close the lreceiver pressure-port.
The electromagnet comprises a suitable bracket 1, the coil 2, and the core 3.
The electromagnet herein represented is of the solenoid type, and the core 3 is fitted to slide vertically in a tube 4, the lower end of which is provided with a removable cap 5,

x the said chamber. vided with a pressure-port 9, which is adapted their pipes 25 are shown as connected 'Patented oct. 30,1906.
which cap serves to support the core 3 when `the ma net is denergized. v
The racket 1 of the electromagnet is surmounted by the valve-box 6, the vsaid valvebox having achamber 7, the up er end oi.V which isclosed by a top cap 8, w 'ch has a screw-threaded engagement with the walls of This top cap 8 `is pro.-
yto be connected to a receiver 22 through a pipe 23. A suitable valve-seat 1() is provlded through the side ofthe valve-box, which port -11 is arran ed to be connected to the space back of a ischarge-valve 24 of a one-stage at the inner end of the port 9. A pressureport 11` opens into the valve-chamber r7 air-compressor 26 through a pipe 25. In the present instance two discharge-valves 24 and to the common ressure-port 11. A12 is A ring seated in t e bottom of the valve-chamber 7, 'v l the bore of which ring forms an exhaust-port 13, which communicates with-a central exhaust-chamber 14, from which transverse jy ports 15 lead to the exterior ofthe valve-box.
The mouth' of the port 13 is provided with a valve-seat 16.
j The ball-valve is denoted by 17'and normally restsupon its seat 16, leaving communication. open between the receiver pressureport and the discharge-valve pressure-port.
- The valve-box 6 is provided with a stepped hollow, depending portion 18 19, the larger ortion 18 being fitted to the top of the- `racket land the 'smaller' portion 19, being extended into the electromagnet 2 and hav- 1 ing a screw-threaded engagement with the top of the core-tube 4.
A rod 20 rests upon the top of the core 3 and extends with an easy sliding t upwardly through the valve-box into engagement wit the bottom of the valve 17,.l It is desirable that the upward movement of the rod 20v and core 3 when theelectromagnet 2 is energized be retarded to a certain extent, so as to prevent a too'rapid shifting of the valve 17.
This object is accomplished by making the valve-box 6 of some magnetic material-such, for instance, asmagnetic ironso that when the electromagnet 2Kis energized a certain amount of ma netism lis imparted to the' valve-box 6. i he attraction of the rod 20 to port, an exhaust-port and a dischar e-va alternately opening and closin the pressureV su ply and exhaust ports to t e dischargeva ve ort. i y
