The shroud is telescoped rotatably over the motor unit of the machine and is suspended from the suction line which, in turn, is pivotally supported on top of the motor unit and is adapted to be turned relative to the handle of the machine to enable maneuvering of the machine without interference from the suction line.
6 Claims, 2 Drawing Figures ABRADING MACHINE WITH DUST COLLECTING UNIT BACKGROUND OF THE INVENTION This invention relates to a portable abrading or sanding machine having a motor unit with a rotary shaft which drives a generally circular sanding pad with either rotary motion or compound orbital and rotary motion, there being a handle projecting outwardly from the motor unit to facilitate maneuvering of the sander. More particularly, the invention relates to a sander of the type in which a dust collecting shroud overlies and extends around the sanding pad and supports a suction line which communicates with the interior of the shroud. Dust created during the sanding operation is confined within the shroud and is continuously sucked out of the shroud by a vacuum unit connected to the suction line.
SUMMARY OF THE INVENTION One of the aims of the present invention is to provide a sander having a new and comparatively simple dust collecting unit which, when compared with prior arrangements of the same general type, enables the sander to be maneuvered more freely and with less interference by the shroud and the suction line.
A more detailed object is to achieve the foregoing through the provision of a novel dust collecting unit in which the suction line is pivotally supported on the top of the motor unit and may be turned to various angular positions relative to the outwardly projecting handle so as to enable the sander to be located in the best position for sanding without being obstructed or encumbered by the suction line.
A further object is to utilize the suction line for supporting the shroud on the sander and to take advantage of this arrangement to enable turning of the shroud to different angular positions relative to the handle for the purpose of exposing different peripheral portions of the sanding pad through an opening in the shroud, the exposed portion of the pad being capable of sanding within a corner or the like without interference by the shroud.
Still another object is to locate the suction line for use as a hand rest for applying pressure to the sanding pad and also for use as an auxiliary handle.
The invention further resides in the novel manner of mounting the shroud and the suction line for universal swivelling on the motor unit and for quick and easy detachment from the motor unit.
.These and other objects and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a new and improved sanding machine incorporating the novel features of the present invention. I
FIG. 2 is a fragmentary cross-section taken substantially along the line 2-2 of FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in the drawings for purposes of illustration, the invention is embodied in a portable abrading machine orsander having a motor unitll with a rotary drive shaft 13 for driving a sanding pad 14. In this instance, the pad is driven with a combined rotary and orbital motion but it will be appreciated by those familiar with the art that the pad could be driven with various other combinations of motions or with rotary motion only.
- In the present instance, the motor unit 11 comprises a rotary air motor 15 (FIG. 2) encased within an inverted cup-shaped housing 16 and receiving air under pressure through a flexible hose 17 (FIG 1) connected to the free end of a handle 19 and communicating with the motor through an air passage in the handle. The drive shaft 13 projects downwardly from the lower end of the housing and into a carrier 20 to which the abrading pad 15 is attached, the pad comprising a circular elastomeric disc 21 sandwiched between a metal plate 23 and a sheet 24 of abrading paper such as sandpaper. Suitable mechanism (not shown) is housed within the carrier and is connected between the latter and the shaft 13 to cause orbiting and rotation of the carrier and the attached sanding pad when the shaft is rotated.
As shown in FIG. 1, the handle 19 is anchored to and projects outwardly from one side of the motor housing 16 and carries a lever 25 which may be depressed to open a valve (not visible) and thus enable pressurized air to flow to the motor 15. When the pad 14 is pressed against a work surface, the handle 19 may be grasped and the entire motor unit 11 may be turned relative to the pad about an axis generally coinciding with that of the shaft 13.
To protect the operator of the sander 10 from abrading dust and to reduce the amount of dust in the work area, a dust collecting shroud overlies and encircles the sanding pad 14 and communicates through a suction line 31 with a vacuum unit (not shown) operable to suck dust from the shroud. As shown in FIG. 2, the shroud comprises a ring-like member telescoped over the motor unit 11 and formed with a generally horizontal top wall 33, with an inner depending skirt 34 and with an outer depending skirt 35. The shroud is formed of flexible but self-sustaining plastic and preferably is transparent to enable the operator to see the peripheral edge of the sanding pad 14 during the sanding operation.
The top wall 33 of the shroud 30 is spaced approximately V4. inch above the pad 14 while the lower edge of the inner skirt 34 rests lightly on the top of the pad to establish a seal between the pad and the interior of the shroud. The outer skirt 35 is spaced outwardly about /4 inch from the peripheral edge of the, sanding pad 14 and, as shown in FIG. 2, supports a ring of flexible bristles 36 which form a continuation of the outer skirt. When suction is applied to the shroud, the brushes seal against the work but not so tightly as to impede movement of the sander 10 or to cause the suction to lock the sander to the work. The brushes also serve to confine the dust within the shroud and to loosen dust which tends to cling to the surface of the work so that such dust may be exhausted through the suction line 31.
In accordance with the primary aspect of the present. invention, the shroud 30 and the suction line 31 are supported on the sander 10 in a novel manner which permits turning of the suction line to various angular positions relative to the handle 19 so that the suction line may be easily moved to an out-of-the-way position and enable unencumbered maneuvering of the sander within confined areas such as corners or the like. This is achieved by mounting the suction line pivotally on the top of the motor unit 11, by suspending the shroud from the suction line and by permitting the shroud to turn relative to the motor unit. With this arrangement, the suction line may be turned relative to the handle and to a position which is the most convenient and less obstructive for the operator at any given time.
More specifically, the suction line 31 herein comprises a generally U-shaped metal pipe having two generally vertical portions 40 and a substantially horizontal portion 41. The horizonal portion 41 overlies the top of the motor housing 16 and is formed with an extension 43 which projects outwardly beyond one of the may place his hand to apply downward pressure to the sanding pad. Also, thehorizontal portion 41 andthe outwardly projecting extension 43 thereof provide an auxiliary handle which the operator may use in con- 5 junction with the handle 19 for the purpose of maneuvertical portions 40 and which is connected to a flexible hose 44 leading to the vacuum unit.
To support the suction line 31 pivotally on the sander 10, a pivot connection in the form of a ball 45 (FIG. 2) is anchored to the underside of the horizontal portion 41 and is adapted to telescope with a snap fit into a hole or socket 46 formed in the top wall of the motor housing 16 in vertical alinement with the shaft 13. The ball preferably is made of resiliently yieldable plastic and, when pressed into the socket, is compressed inwardly by the rounded upper edge of the socket and then snaps outwardly below the edge. By virtue of the ball, the suction line 31 is capable of pivoting relative to the motor unit 11 about a vertical axis coinciding generally with the axis of the shaft 13 and also is capable of limited rocking about a horizontal axis.
The two vertical portions 40 of the suction line 31 are spaced diametrically around the shroud 30 and preferably communicate with vertically flexible hoses 50 which, in turn, communicate with the interior of the shroud through the top wall 30 thereof. At their lower end, the vertical portions 40 are telescoped within and anchored to the hoses 50 while the latter are anchored securely to short tubes 51 formed integrally with the top wall 33. The shroud thus is suspended from the vertical portions 40 of the suction line 31 and is supported on the motor unit 11 solely by the pivot connection 45. As shown in FIG. 2, the inner skirt 34 of the shroud is spaced outwardly from the carrier and thus the shroud is free to turn relative to the motor unit 11 when the suction line is swivelled horizontally.
With the foregoing arrangement, the operator may swivel the suction line 31 horizontally to different angular positions relative to the handle 19 and thus may move the suction line and the hose 44 to positions in which they present a minimum encumberance either to the hands and arms of the operator or to placement of the sander 10 in the most advantageous position with respect to the work. Accordingly, the sander may be maneuvered more freely without being obstructed by the suction line and the hose. By virtue of the ball 45 and the vertically flexible hoses 50, the shroud 30 may rock slightly in a vertical direction to facilitate movement of the sander over curved or irregular surfaces. If it is necessary to remove the shroud to sand a given area, such removal can be easily effected by snapping the ball 45 out of the socket 46 and lifting the shroud and the suction line from the sander 10 as a unit. When the suction line is attached to the sander, the section of the horizontal portion 41 overlying the motor unit 11 forms a convenient rest pad upon which the operator vering the sander.
If desired, an opening 60 (FIG. 1) may be formed in one side of the shroud 30 by interrupting part of the outer skirt 35 and the top wall 33. As a result of the opening 60, a portion of the peripheral edge of the sanding pad 14 is completely exposed and may abrade a work surface directly adjacent a corner or right angular wall'without being held away from the wall by the outer skirt 35. With the shroud being turnable on the motor unit 11 and with the motor unit being tumable relative to the pad, the opening 60 may be turned to various positions relative to the handle 19 and thereby enable the operator to locate the opening in the most advantageous position to expose the portion of the sanding pad capable of best reaching the work.
