The present invention relates to rug or carpet cleaning machines, and more particularly to machines of this nature having a relatively simple and effective mechanism for removing dirt and cleaning materials remaining in a a rug or carpet after a prior washing operation thereon. Another object of the invention is the provision of a machine of this character having an efficient rinsing mechanism for effectively carrying away all traces of dirt in a thorough and uniform manner without injurious effects upon the fabric being treated.
Another object is the provision of mechanism in a device of this character for causing an effective circulation of the rinsing fluid into and out of the fabric and at the same time causing the nap of the rug to be thoroughly raised to give the surface of the rug a bright, new appearance;
A further object is the provision of an efficient arrangement for circulating rinsing fluid into the fabric and withdrawing it therefrom which operates selectively over a width substantially coincident with that of the fabric being treated.
and effective control means for the operating elements of the machine as well as simple means for an adjustment of such parts.
Still a further object is the provision of a device of this character having a sturdy and compact construction of relatively few parts which will withstand hard usage without likelihood of getting out of order.
To these and other ends the invention resides 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.

Figure 10 is a fragmentary sectional view takenon line 10-10 of Figure 1.
Similar reference numerals refer to simila parts throughout the several viewsof the In a general way the present machine comprises a rotary drum on which the rug is fed past the rinsing and'vacuum elements. The movement of the rug into position adjacent the rinsing element automatically operates the valve mechanism for the rinsingand vacuum devices. 7
The rinsing and vacuum elements are so positioned that the rinsin water passes into the fibers of the rug, and 1s thereafter immediately withdrawn by the action of the vacuum element. The soap and dirt thus loosened by a previous washing operation is thus thoroughlyremoved.
An important feature of the present invention is the proper timing of the rinsing and vacuum elements, so that the vacuum element begins its operation before the rinsing element and ceases its operation after the operation of the rinsing element has ceased. This insures that the water projected from the rinsing element is thoroughly removed after circulating among the fibers so that it has no opportunity to cause any undesirable effects upon the rug such as the running of thecolors.
v The rinsing and vacuum elements are composed of a plurality of independent units and are so arranged that only those units engaged by a rug are actuated as the rug passes through the machine. Those units which are not enga ed by the rug remain idle.
After t e rug hascleared the rinsing and vacuum elements the parts are automatically returned to their normal inoperative positions and are thus ready to receive the next ru to be rinsed.
he present invention is in, the nature of an improvement over the rinsin and vacuum devices disclosed in my copen ing application, Serial No. 138,631 filed September 30, 1926, for a carpet cleaning machine.
Refering more particularly to the drawings, 1 designates the rug cylinder or drum journaled on the frame of the machine in any suitable manner. This cylinder is provided with spines 2 for holding the rug in position thereon. The rinsing and vacuum elements are mounted adjacent the cylinder 1 on another portion of. the machine and will now be described. A plate member 3 is positioned along the face of the drum or cylinder 1 and slidably supports a plurality of vacuum hoods 4.- Each hood is located between gibs 5, 5 secured upon the plate 3 and overlyin a flange 6 upon said hoods 4, to hold sai hoods firmly against said plate. The vacuum hood 4 is formed with a downwardly directed opening 7 in its interior, communicating with a port 8 in the plate 3. At the front of this vacuum hood 4, which is that portion adjacent the cylinder 1, is a throat opening formed with two independent passages 9 an 10, one lying above the other, as shown in Figures 1 and 7.
The side walls 10 of the passages or openings 9 and 10 of the vacuum hood 4 are flared outwardly as shown at 10 in Figure 8. The flaring portion 10 in one hood member meets the flaring portion 10 in an adjacent hood member, and extends to a point somewhat inwardly from the end of the passages.
An inner wall or partition 11 separates the passages 9 and 10 and normally projects outwardly-to a slight distance beyond the ends of the upper wall 12 and lower wall 13 for a purpose to be later brought out. The wall or partition 11 com rises a'metal plate of the form shown in igure 8, and is removably positioned in the vacuum hood by means of cut out portions 10 in the flaring walls 10", as shown at the left in Figure 8. Set screws 10, shown in Figures 3 and 4, are screwed into holes 10 and bear firmly against the lower side of plate 11 to hold it in proper position. The rinsing nozzle castmg generally indicated at 14, is slidably positioned on each vacuum hood 4 for slight forward and rearward movement thereon. This member 14 casting 14 outward is cast integral with a slide element 15 which is engaged between guide lugs 16, 16 which are cast integral with the vacuum hood 4.
The rinsing nozzle proper is formed in an enlarged portion of the casting 14, and has a downwardly directed elongated slot 17 communicatin with a hollow portion 18 for the. urpose o projecting a long thin stream or s eat of water against the rug upon the cylinder 1. At the rear of the casting 14 and communicating with the enlarged hollow portion 18 I provide a screw threaded opening 19 for connection to a source of water supply to be later described. Upon the rinsing nozzle casting 14 and referably integral therewith are bosses 20, 0 upon which are journaled rollers 21 which are adapted to engage the rug before it reaches the rinsing and vacuumelements.
I provide means for urging the y on the vacuum hood 4;.
This means comprises a lug 22 on the casting 14 and provided with a screw threaded opening therein to receive a stud 23. Plate 24 is secured at the rear of the hood member 4 in any desired manner, and projects there above to a height approximately equal to lug 22. The plate has an opening 25 therein aligned with the aperture in lug 22 so that the end of stud 23, when secured in lug 22, may pass freely through said opening 25. A compression spring 26 surrounds the stud 23 and bears at one end a ainst lug 22 and at the other end against p ate 24. The end of stud 23 is threaded a considerable distance on each side of plate 24. Upon this threaded portion I provide adjusting nuts 27 and 28 which serve to limit the reciprocating movement of casting 14 upon the vacuum hood 4. Thus it will be seen that by adjusting the nuts 27 and 28 to varying positions alon the stud 23, I may vary the compression 0 spring-23 and also vary the distance which the rinsing nozzle may move with relation to the vacuum hood. A stop member 29 in the form of a plate is secured at the front of casting 14 and extends downwardly therefrom to a slight' extent, so as to contact with the upper wall 12 of the hood 4 when the casting 14 has moved rearwardly upon the hood 4. a
As heretofore polnted out, the vacuum hood 4 is slidably mounted upon plate 3 for forward and rearward reciprocation. This vacuum hood is preferably arranged to be urged outwardly toward the cylinder 1 by the following mechanism: An arm 30 (Figure 5) is pivotally mounted on the gib 5 at 31, and has an end 32 screwthreaded to accommodate a set screw 33, the end of which bears a ainst the plate 24 secured to the rear of t e vacuum hood 4. The opposite end of the arm 30 is connected to a tension spring 34. This spring is connected at its other end to a member 35 secured upon the plate 3. Thus it will be seen that the spring 34 causes the end 32 of the arm 30 to exert an outward pressure upon the vacuum hood 4.
Referrm to Fi ure 1, it will be seen that the plate 3 orms t e upper wall of a vacuum chest 36'having side walls 37 and 38 secured to the plate 3 and secured to-each other at their lower edges at 39 in any desired manner. As heretofore pointed out the plate 3 is provided with a port 8 adapted to connect the vacuum hood 4 with the vacuum chest 36. The vacuum chest 36 is suitably connected to a vacuum or suction pump not illustrated.
A slide valve member 40 is mounted to close the passage between the vacuum chest and the vacuum hood 4.
This slide valve 40 ma be operated by the following mechanism: pon a fixed portion 41 of the frame of the machine I provide a bracket member 42 to which a lever arm 43 is pivotally connected at 44. The lower end 0 the lever arm 43 is bifurcated at 45 to receive a lug 46 on slide valve 40. It will be seen that the bifurcations on the lever arm 43 are of une ual length for a purpose which will be heremafter brought out. The lever arm 43 is provided with a screw threaded aperture 47, (Figure 5) just above its bifurcated portion. A set screw is threaded into said aperture and is so positioned that its end contacts with the end of the screw 33 upon arm 30. It is readily apparent that the position to which the slide valve 40 may be moved can be varied by turning said screw 48 within the lever arm 43. A tension spring 49 is connected at one end to lever arm 43 and at the other end to casting 14. An adjustable link member, designated generally at 50, is connected at one end to the upper part of arm 43 in any one of the series of holes 51 by means of a pin 51' and at its other end is connected to a lug 52 on casting 14 by means of a pin 53. The link is composed of two sections 54 and 55 adapted to be adjustably connected by a screw 56 and slot 57 in the respective sections. This screw and slot connection is a well known means for readil changing the length of a link such as lin 50.
I provide a source of water supply which is illustrated in Figure 1, comprising a conduit 58 to which a valve 59 is connected in a well known manner. This valve member is clearly shown in detail in Figure 9 and comprises chambers 60 and 61 connected by a passage 62. The flow of water through passage 62 may be controlled by means of a valve element 63 provided with a stem 64 projecting upwardly from valve casing through a packing nut 65. A yoke member 66 having a ring section 67 is secured to the top of the valve casing 59 by means of a set screw 68. The valve stem is threaded at the upper end and provided with'a nut 69. Between the nut 69 and the packing nut I provide a compression spring 70 which is adapted to urge the valve element 63 upwardly to normal y close the assage 62. The chamber 60 has an upwardl turned portion which is interiorly threads and adapted to receive a nipple 61 secured inthe end of a hose section 62. The other end of the hose 62 is connected in a similar manner to the screw threaded opening 19 in the casting 14 heretofore mentioned.
I provide mechanism whereby when the slide valve 40 is moved rearwardly or to the left as seen in Figure 1', the valve stem 64 of the valve 59 w1ll be depressed. This mechanism comprises a cam arm 71 secured at 72 on the plate 40 and provided with a camsurface 73 at its outer end. This outer end of the cam arm 71 is adapted topass within the yoke 66 through a slot 74 formed therein. The cam surface 73 thus engages the end of the valve stem'64 and depresses it when the cam arm moves rearwardly with the slide 40.
As shown in Figure 2, the lower end of the lever arm 43 may have a movement greater:
than that to which it is desirable to stop slide 40. In this event, the shorter bifurcation on lever 43 allowsthe end of 43 to be disengaged from the lug 46 on slide 40 until its return movement when the bifurcated portion again engages with said lug so as to bring the parts to their normal inoperative position.
The operation of the device is as follows:
Assumin that the rug. has been placed upon cylinder 1 and the cylinder is rotated downward toward the rinsing and vacuum mechanisms, it will be seen that the rug will first engage the rollers 21 journa-led on the rinsing nozzle 14. The rug will cause the rollers 21 to move rearwardly against the compression of spring 26 until the stop plate 29 strikes the upperwall 12 of the vacuum hood. This movement, though slight, produces a much greater movement of the end of the lever arm 43, causing the slide valve 40 to open substantially to the position shown in Figure 2 to connect the vacuum chest with the vacuum nozzle, and at the same time moves the cam surface 73 on the cam arm 71 against the end of valve stem 64, thereby depressing the valve, allowing water to flow from the conduit 58 through the hose to the rinsing nozzle in casting 14.
The relation of the parts is such that the slide valve 40 will have been opened a substantial distance before the valve stem 64 is actuated by the cam surface 73. This insures that the vacuum nozzles will be operating effectively by the time the flow of water from the rinsing nozzles is started. The valves controlling the nozzles are closedin the reverse order. First the rinsing nozzle is allowed to close by reason of the movement of the cam away from the valve stem 64. At the time when the valve 59 is completely closed, the slide .cylinder 1, contact members or rollers 21. If the rug is ing operation. It will .water after passing 40 will still have a short distance to move before it closes the vacuum chest. After all of the water discharged from the rinsing element is drawn in through the vacuum element the slide 40 will reach its closed position.
It Wlll be understood that I rovide a plurality of nozzle units across tie face of the each unit having its own set of narrow it may actuate only two or three of these units, thus leaving the remaining units idle which are not necessary in treating the rug assing through the machine.
W en the rinsing and vacuum nozzles are operating with a rug in position on the cylinder, it will be seen that a stream of water is projected downwardly at an angle into the fibers of the rug, thoroughly removing any soap and dirt remaining from the prior washalso be seen that the into the fibers of the rug withdrawn through the upper portion 9 of the vacuum hood 4:. The lower passage 10 serves to remove the residue of the water not taken up through passage 9, so that the rug leaves the machine in an unsaturated condition free from the running or dripping of any of the cleaning liquids that have been applied thereto. This feature has been shown and described and broadly claimed in my copending application above mentioned.
The vacuum chest is provided with suitable means for receiving and carrying off the water that flows into it through the vacuum hood 4. Such means is a matte-r of detail and has not been shown herein.
The projecting edge of the wall or partition 11 serves to eiiect a very thorough preliminary separation of the rinse water from the fibers of the rug and thereby permits the lower throat opening 10 to produce a maximum effect upon the nap of the rug to thoroughly raise all of the fibers so that they will lie free and untangled, thus giving the rug a bright new appearance.
