attgphing arms 45 and 46 extending backwardly from the chamber-head 34:, there be ing an opening 47 in the arm 45- ior the passage of the electric-cord and there being an opening 48 to register with the screw-threaded opening 19, so that a screw 4-9 maybe inserted to hold the motor and pump in place in the main chamber; the casting be- 111g turned to finish the peripheral faces of the chamber-heads to fit closely in the main chamber 2 thereby completing the pumpinlet-chamber 33 and the pump-outlet-chamber 35.

The rotary-piston-head 4:9 is cylindrical and of less diameter than the piston-,chamher and-has a journal 50 extendingthrough' the ,bore of the bearing-block 43 so as to mount the rotary-piston-head eccentric inthe piston-chamber; the length of the piston-head fitting the length of the pistonchamber and there being a longitudinal transverse slot 51- through the piston-head from its forward end to receive the pistonvanes 52 and 53, said vanes being held against the inner-surface of the pistonchamber by centrifugal force and said vanes being made of aluminum to reduce the weight thereby reducing the centrifugal. force and reducing the friction. The journal 50 has a bore 54 extending from its rear end to receive the shaft of the motor, and

a transverse slot 55 extending from the bore 5st to receive the fiattened end of the motor. shaft. The piston-chamher-head 56 is bolted to the end of the piston-case to close the piston-chamber, and an internallyscrew-threaded boss 57" projects forwardly from the piston-head to receive the screw 57* inserted through the screen 21*.

The motor C is shown in detail in Figs.

2, 3, and 10; The frame 57 of the motorfield fits close in the main chamber 2 and butts against the ends of the motor attaching- arms 45 and 46, the ifrontwindings 58 fitting between the arms, 'iherear motor no hearing 59 is formed at the center of a hemispherical-cap-plate 60, said capplate having a shoulder 61, which abuts against the end of the cylinder and a flange 62 extendsinwardly and fits againstthe side of 5 the motor-field frame 57, there beingalropenings 63 through the cap-plate 60. The motor'shaft 64 is mounted with its forward end in the journal 50 of the piston-head, the

front end 65 of the motor-s1aft being fiat- 12g tened'to fit non-rotatably in the slot 55. After the parts are placed together the screws 66 are passed in through the airopenings 63 and inserted through the flange 62, through the niotor-field-irame 57 and screw-seated in the ends of the motor-ate; taching-arms i5 and 46, thus holding the suction-mechanism and motor together as a single organization, as shown 1n B 1g 3,

so that it may he manipulated as a whole 134 a edi n the main. chamber am shown inF1g.2.- l a -The dust-receptacle i s' shown in detail v in"Fig's.' --2,1:4- and 5. The "dust-receptaclecap-plate may be unscrewe cap is acasting comprising the:bell-shaped central body 67 havin" an exterior-screw thread. 68 on its forwa having an outwardly projecting sack rim 68 on its rear and large end; the annular web-69 extending outwardly back of the screw thread 68; the exteriorly-screwthreaded-flange 70 extending backwardly from the web 69 and fitting in the thread v 4; and the annular flange 71 extending outwardly from the flange 70 and having a finished face 72 to match the face 3, there being a gasket 73 between the faces 3 and 72 to make a tight-joint; and the periphery 74 of the flange 71 being knurled. The dustsack 75 has longitudinalloops 76 around its open end and an endless-elasticbflnd 77 is 'located in theloops to contract'the end of the sack, so that when the rim B8 is inserted into the mouth of the sack the elastic-band 77 will contract behind the rim and hold the sack in place and make a tight joint,'so that the dust-receptacle may be applied to the main chamber 2, as shown in F1g. 2, and so' that when it is desired to em ty the sack the d and the sack removed. Thesuction-nozzle E is a casting comprising the parallel- lips 78 and 79 between which is the mouth opening 80; the outer surfaces of said lips being rounded so as to.

run smoothly forwardly or backwardly u on the floor, and the inner faces of said ips being straight soas to form sharp edges to serve as scrapers for loosening the dirt, the rear scraper throwing the dirt into the mouth when the machine moves forwardly and the forward scraper throwing the dirt into the mouth when the machine moves backwardly; and the neck 81 extending upwardly andbackwardly from the lips 78 and 79. A union nipple 82 is screwed into the.

neck and a union-nut 83 connects the nipple to the cap-plate, so that the dust passing 1nwardly through the mouth'will pass into the sack. The inlet to the dust-receptacle is above the dirt in the sack so that the dirt is not likely. to spill out through the nozzle while the machine is right side up on the floor. The motor brushes 65? are mounted through the cap-plate. e

Thus we have constructed a self-contained traveling suction-cleaner. The weight of the forward end of themachine rests. upon the suction-nozzle and' both lips of the nozzle engage the 'floor at the same time and it is not necessary to manually press the nozzle upon the floor. The wheel under the front end of the machine is normally raised from the floor and only comes into use when the suction-nozzle is removed. The suction and small end and;
