To aZZ wiom t may concern: i

Be it known that 1, ADAM A. LONG, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful improvements in Cleaning- Machines; and l do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

The present invention lrelates to cleaning machines and it has for an object to provide a construction having' a substantially portable brush or other agitator with suction producing means so located that the operative will notfbe required to support the same during the cleaning operation. n Another object of the invention is to provide a construction in whichthe driving of the brush or agitator will cease when the latter is moved to a certain position. To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.-

ranged on a support or table 1 and acted upon by an agitator 2 which in this instance is in the form of a rotary brush partially inclosed by a casing 3, the brush being preferably carried by a shaft -l journaled in thecasing walls and extended at one end beyond one of said walls to turn in bearings 5 and 5a arranged within a tubular member 6.

The latter is secured to and held in spaced relation to the casing 3 by brackets7 that are bolted at 8 to said casing, the axial movement of the shaft 4 in the tubular member being prevented by securing a disk 9 thereto at one end so as to cooperate with the outer face of the bearing 5a. rll`his disk is preferably engaged v:by a screw plug 10 introduced into the end of the tubular member 6 and preferably carrying an oil cup 11 which feeds oil to the disk for the lubrication of the bearing 5a, the bearing 5 being lubricated by a cup 12.. The tubular member 6 preferably serves as a handle for the control of the brush or agitator and may be inoased by a rubber sleeve 13 and a removable rubber cap 14e, both of which facilitate the manipulation of the machine and at the same time prevent oil passing from the end of the tubular member.

rFhe driving of the brush or agitator 2 and the suspension thereof is preferably eected byV an endless cable 15 which passes about a pulley 16 rigidly secured to the shaft 4lbetween the casing 3 and the tubular member 6. 'llhe cable 15 has its two strands leading upwardly from the pulley 16 about a pair of pulleys 17 arranged side by side and mounted on frames 18 which are pivoted on parallel aXesiat 19 to swing laterally with relation to the cable so that the brush may be carried toward either end of the table without shifting the cable from the pulleys. From the pulleys 17 the two strands of the cable pass rearwardly to a pair of pulleys 2() and thence downwardly about a pulley 21. Preferably the pulley 21 is supported on an upright frame coniprising two rods 22 secured at the rear of the work support l and having at their upstoppage,

v counterbalance the brush and the pai ts carried thereby there is employed a weight 24,

or other suitable device, which preferably carries a pair of rollers 25. coperating wlth both strands of the cable 15 between the pairs of pulleys 17 and 20. rihis weight is guided vertically on guiderods 26 depending from the arm 23 and having a stop 27 at their lower ends weight and sustain the latter when the brush is moved upwardly to a certain position. Of course, when the weight reaches this stop all tension will be removedfrom the cable 15 and driving connection between the pulley 21 and the brush 2 will be broken.

The cable, unless otherwise affected, will not stop immediately but willy continue to move under its own momentum and with the end in view of effecting an immediate there are employed brakes 28, in this instance in the form of levers pivoted to the weight 24 at 28a and having friction faces 28b to coperate with sides of the pulleys 25 and stop rotation of the latter, thus imposing friction on the cable 15. rl`he levers in this instance depend below the weight 24 so that they may engage the stop.

27 to beshifted into cooperation with the pulleys 25 when `the weight moves to said stop. Springs 28C act on the levers to hold them out of contactuwith the pulleys and against the stops 28d.

The brush may be supported in its inoperative position upon a device comprising two .spring arms 29 clamped to one of the rods 22 and having their forward ends converging at 30 to facilitate their introduction through a loop 31 formed on the casing 3 inclosing the brush. An adjustable stop 29a may be arranged on the arms to limit the movement of the casing on the arms 29.

While the brush is supported in inoperative position the cable 15, of course, is slack and consequently it is desirable to provide some means to prevent the cable leaving the pulley 16. This is accomplished in this instance by a pair of pulleys 33 coperating with the outer sides of the two strands of the cable and preferably carried'upon a movable or swinging member 34 which is journaled on the tubular portion 6 to turn about an axis coincident with `the axis of shaft 4, thus permitting the brush to be carried to either end of the table without imposing any strain on the cable. To prevent the swing member moving too freely,

a friction member 35 in the form of a plate guided on headed studs 36 is pressed toward' with a passageway to cooperate with the l the swinging member by helical springs 37 surrounding said studs, stops 38 projecting into the path of the swinging member at the limits of the movement of the latter. rThe swinging member 34 may also carry a pin 39 which lies between the two strands of the cable and prevents the latter from leaving the pulleys 33.

For the purpose of removing the dustv agitated by the brush 2, the casing 3 surrounding the brush is preferably provided 48 having an intake arranged at its bottom and to one side of the brush. The outer wall 48a of the passageway depends lower than the inner wall 48b so that the dust may enter lfreely into the pasageway but will be prevented from being carried beneath the casing. In order that, all possibility ofthe latter action will be obviated, the wall 48a carries a depending flexible strip 48d which provides a tight joint between the material being cleaned and the casing for any operating position of the machine. It 'is also desirable to control the size of the intake opening and to this end a piece of pliable sheet material secured to the inner wall 48b of the passageway and is extended upwardly therein. By moving the end 48C of the sheet material the opening may be varied in size to meet the condition under which the machine is operating.

' To the end of producing suction in the passageway 48, a flexible dust conductor or tubing 47 connects with the casing and leads to a stationarily-supported suction-producing means, such for instance as a fan 4() which may be supported on upright rods 22. The tubing 47 may be supported in any moved to either end of the work support without twisting the tubing. The swinging movement of the elbow is limited by stops 47 b lying on opposite sides of the elbow and carried by a split clamp or collar surrounding the reduced end of the member 41. The

latter has an enlarged chamber 42 and is preferably secured to the fan casing by headed pins'43 on the casing and curved locking slots 44 on the member, a rotation of the latter effecting a locking or unlocking'of the parts and a spring pressedbolt 45 on the member coperating'with the fan casing to hold the member against movement on the fan casing. The enlarged chamber 42 is pro.- vided to preventv large materials entering the fan casing and in order to cause said materials to collect in the chamber, a cone 13( natale? shaped screen 46 is preferably secured to the fan casing. rlhis screen is self cleaning as its apex is in line with the direction of the air current leading to the fan, thus causing the air to move all lint or the like to the base of the cone s o that the latter is always cleared.

From the fan casing the dust is carried to a pipe 50 which through a union 51 connects with the threaded nipple 52 secured to the top 53 of a dust container 54 'which has its side walls perforated to permit the escape of air. rlhe top is provided with an annular groove 55 which is secured to the outer edge of a bag 56 of textile material depending into the container54 to collect the dirt.

The fan shaft 57 has a pulley thereon Connected by an endless cable 58 with the pulley 59a on the shaft 5,9 which also carries the pulley 21. On the shaft 59 there is also arranged a pulley 60 to which an endless cable 61 connects, the latter in this instance being driven by a motor 62 arranged on the table 1.

Assuming the motor 62 to be running and that the brush is supported upon the arms 29, the operator having placed the goods to be cleaned upon the table grasps the handle of the brush and removes the latter from the support 29. As soon as the brush is moved to a position to elevate the weight 24 from stop 27 the cable l5 begins to ymove, thus rotating the brush. Upon the engagement of the cloth bythe brush, any dust in the cloth will be carried to the intakeof the passage 48 and by the fan drawn through the tube 47 and discharged into the bag 56 which will permit the'gescape of air but will retain the dust particles. `its soon as the brushing operation has been completed the brush is placed upon the arms 29 thus lowering the weight 24 to the stop 27 and causing the latter to shift the brakes 28 into engagement with the pulleys 25 which will eect the stoppage of the cable 15. When the bag 56 is filled with dust the coupling union 51 is manipulated todisconnect the top 53 from the pipe 50 so that the bag 56 may be removed from the chamber 54.
