DUNN, oFfEAsT ORANGE, NEW JERSEY, assIeNoRs, BY MEsNnAssIeNMEnTs, .TO VACUUM ENGINEERING COMPANY, A GORPO- suo'rron arranajrns son PNEnMArIo cnnanme sYs'rnM lie itknown that we, WILLIAM LooKE, a citizen of the, United States,- and a resident of ,,Westfield, count% of Union, State of New Jersey,.and ELIAS 'DUNN, a citizen of the invented certain new and useful Improvejments in Suction Apparatus for Pneumatic Cleaning Systems, .of which-the following is a full, clear, and complete disclosure.

Briefly stated, this form of our invention relates to improvements in apparatus for produclnga pneumatic suction for 1136111 is:

connection with systems bf" removing'dirtand dust through a partial vacuum or neumatie suction, and'co'mp'rises a device 111 the e pump; that is provided with such a' constructlon that the parts thereof are com letely protected from the action of dirt or ust passing {through the same, and

whereby the dust-laden air maybe taken directly, into the apparatus, thus avoiding necessity of using costly and undesirable 'separatin apparatus for extracting the dust 'and'dirt om the air. V i I Thefur'ther object of our invention .in- "volving the-construction referred to, is to prevent the possibility of serious ex losion y the ignltion of fine particles of ust ,in rapid motion, and is obtained by thoroughly,

he construction -of this 'form. f

istonf located in a piston c amber aboveftlie-body' of the liquid, such as water,

plunger or piston; also means for completely protecting the piston, said means beingl in w 'ch areprovided with a supp y of liquid, such as water, so that said spaces are, continually tact with the piston is completely carried away. -The construction also embodies a certain arrangement of parts, hereinafter to be'more fully pointed out, whereby the arrangement of the suction apparatus is greatly simplified and its efiiciency lncreased.

The apparatus above referred to produces a vacuum or partial vacuumwhich is trans mitted to suitable conduits or pipes through a suction nozzle, which is" a aptcd to e passed over the surface to be cleaned, so

that'the dust and-air, or dust, air and water that are thereby caused to enter the nozzle 7 are carried through the conduits to the suction device, where they become'mixed with liquid, the mixture then being ejected therefrom and discharged into the sewer or other waste ,pipe. For a full, clear and exact description of this form of. the invention,

reference maybe had to the following speci fication, together with the. accompanyin drawings forming. a part thdreof, in whic the figure shown is a vertical sectional view of the suction apparatus taken substantially on the axial 11116 of the piston chamber.

.being connectedwith suitable valves2 for :iplerating the piston within the cylinder 1. i e said piston is attached to a piston rod 3, which, extends through the suction of pump chainber"4 and carries the ump piston 5.

The pistonrod 3 extends be ow the" suction cross-head 6 which carries the connecting rod 7, acting upon the transverse shaft S, by means of a crank (not shown), earned by said shaft 81in the ,wellknown manner. The

valve rod 9 for operati the valves 2 is also connected with said sha t 8 by means of the usual. eccentric or other similar device. The pump piston5 is provided at its upper'end with an suitable packing such as'shown at 10, the ower portlon of said piston 5 being somewhat smaller than the interior dimensions of the pump chamberA 'so as to provide s ace for. an apron or'cylindrical guard 11,

This form of theinvention is, a modification of. the suction apparatus described and chamber and is connected with',the usual he apron 11 extends downwardly from the portion of the piston carrying the packing 10 and is substantially concentric with the lower portion of thefpiston 5. The lower portion of the pump cylinder 4 is provided with a corresponding upwardly extending apron 12, which works 111' the space between the apron 11 and the lower portion of the piston About the central portion of the cylinder 41s provided a circular groove or channel 13 which is connected at one point with a'water inlet pipe, as indicated at 14. At the lowezcommunicates with the saturation chamber 16 formed within the casing 17. In the lower portion'ofthe chamber 16 are placed suitable inletvalves 18 and inthe u per portion of said chamber 16 are place suitable outlet valves 19, A discharge pi e 20 communicates with the saturation c amber '16 above the level of the outlet valves 19. Within the saturation chamber 16 are provided suitable battle plates 21-located so as to be below the surface of the liquid in said chan'iber. The lower portion of the suction chamber 16 is connected with a suitable inlet conduit 22 which communicates with the pipes or tubes to whichthe suction cleaning instruments are attached.

When the device is in operation, water is admitted through, the pipe 14 and fills the,

space between the apron 12 and the walls of the cylinder 4,thereby providing a waterseal'into which the apron 11 extends. The

' constant'supply of water through the pipe14 causes the same to overflow the upper edge 7 of the apron 12 and run downward into the lower portion of the suction chamber 4. The water level in the suction chamber 4 and consequently in the saturation ch'amber 16'is maintained substantially at the pointindicatedby the. dotted 'lineA, said saturation chamber 16 thereby being filled with water up to a point slightly belowthe end "of the discharge pipe -20.. The constant flow of the water through tlid inlet 14 and around "the aprons 11 and 12 constantly flushes out .the spaces around and between said apron, thereby keeping them clean and free from dirt and grit whlch are drawn into the suction chamber 16 and intojthclower portion of the pump chamber l ll' As the pum piston 5 reeiprocates, air and dirt, or air, irt and water, are :periodically drawn into' and expelled from the pipes 22 and 20, respectively, thedirt being thoroughly mixed with the water in the saturation chamber 16 'byj' a discharge through the, baffle plates 21. The mixture of dirt, waterand'air is expelled through the discharge pipe .ZO an'd )asses off directly to' the sewer or through a muffler, as described in conncctlon with they previous form of this device. 1 It should be .noted that the main differences between this form of the invention and the'form previously described is that the saturation chamber Y soa ssa is situated at one side of the pump instead -of immediately "below' -thelatter, and that the automatic inlet and outlet valves for the water have been omittedfwhile the.

outlet valves for, the mixture are placed in the saturation "chamber instead of in the piston. .It is obvious that this form of the suction apparatus may be operated by-"other means than a steam driven piston, such'as by an electric motor as shown inconnection with the previous form of the apparatus;
