LYMAN n. ROBERTS, or RUTHEMORD, -NEwjJnRsEYL VACUUM CLEANING APPARATUS.

To all 'whom it 'may concern:

Beit known that I, 'LYMAN the United States, and residing and State f/at Rutherford, countyot' Bergen,

and useof New Jersey, haveinvented new t'ul Improveiiient's in Vacuum Cleaning Apot which the tollowing is a speci-` aratus, 'cation This invention relates to a vacuum cleaning apparat-us comprising a complete plant adapted to be permanently installed within a building and providing means :t'or etlecnishings thereof.v

The device is compact in form, may be readily manipulated and is not 4apt to come out ot' order by an objectionable accumulation of dust.

In the accompanying drawings: Figure 1 is an elevation partly 1n sectionfot' the principal part of the., apparatus, Fig. 2 a vertical cross section on line 2 2, Fig. 1, Fig. 3 a rear view partly in section of the pump, Fig. 4 a diagram of a building showing it provided with my improved cleaning apparatus, Fig. 5 a detail of one of the exhaust nozzles, and Fig. 6 a detail of the face plate. l

Upon a frame 10 is supported a vacuum pump which is shown to consist of an exof cooperating bellows 12, the latter being aetnated by an electro-motor 13. This motor, by gearing 14, turns a crank shaft 15journaled in bearings 16 and connected to the movable boards 17 of the bellows links 1S. Chamber 11 isv adapted to communicate with each of the bellows 12 by exhaust ports 19, controlled by outwardly opening iiap .valves 20.' In likey manner, the -movable board 1710i: each bellows is providedwith vents- 21 controlled by similar outwardly These valves are formed of leathe'ror similar flexible material and are permanently secured kto boards at their lower ends, while their upper endsjare connected' to the.y boards by tension spjlvfiiigs 23. Yokes distance below springs 23`hold the upper movable ends, ,ofl tlrevalves against boards 17.- Opposite'a'h vent'or port, valve 22 is reinforced by a liber disk 25..

The exhaust chamber 1.1 comnnniicates b v pipe 26 having coupling 27.with the top ol a dust collectingv'essel 28 adapted to contain Into this liquid dips Specification of Letters Patent.'

the lower endvof a` suction pipe 29 which passes through the wall of the vessel and tolector above referred to forms a permanent lixture of the building as indicated in'Fig. 4. Vessel 28 is'preferably made conitorm widening from top to i is provided with a tapering bottoni 30 which by pipe 251 having cock 32 is connected to the sewer. The mouth of pipe 2G-is screened as at 33 and below said mouth,'there is arranged within vessel 28,21 guard :l having nipple 35. This guard slopes downwardly from the .walls of vessel toward 'the center thereof and communi# cates at its lowermost point .withthe nipple 35, so that any dust laden moisture .that may be sucked into the guard pipe 2G will flow down along the funnel and be returned to the vessel through the nipple. lYater niaybe introduced into vessel 28 through a pipe while a gage Ell permits the water level to be readily ascertained. Suction pipe 29 coin- 38 with the several rooms of the preferably'through the base-lmardsi) and through face plates 10 secured to said baseboards. Flexible caps mouths of nozzles 38, against which they are tightly held b v the suction within pipe 29. A switch 4'. carried by plate 40 serves to con- 4trol electro-motor 13, so that the sanie'inay be started or stopped from any .oiieof the rooms comprised within the system.

i In use, cap l1 is removed and a hos'e provided with an appropriate suction .implement is coupled to the nozzle. Upon starting the motor, by switch 4'2. suction will be created in the hose to piieumatically remove lthe dust and convey into dust collector Q8 below the liquid the saine through pipe level, thereof. During thisl operation. the resulting spraying of. ..the water will be checked bvthe taper'ti'ig toiih'of-the vessel and also by the.fiuinelshaped guard '-l which protects the mouth of 'pipe 2li. The dust entering vessel :ZS will be laid by being fai-igedinto the water. the heavier particles being lighter partichswill tloat on the water. In this wa'it'l .p a,.-:--fage votdust and also of 'the washing liol'uidinto the lpump is etfectivel'i-v prevented. so that .choking is obviatedand the lit'e of tht` pump is prolonged. The pol# lntcd water may be drawn otl'l from vessel QS. whenever required, through pip'e 31 and bottom as shown and funnel shaped' l1 normally 'close the precipitated upon bottom 30 while the and dust'colfresh water may \1.'4 In va device of.
