UNITED sTTEs PATENT oFFlcE.,
PORTABLE BELT SANDER.
Application led December 81, 1924. Serial No. 759,150.
The present invention relates to a belt sander and has for its prime object to pro- -vide a portable device of this nature possessing a simple, efficient, and compact structure,
one which is reliable in operation, inexpensive to manufacture, durable, strong, and well adapted to the purpose for which itis designed.
The device also lcontemplates the construction of a device which can be readily carried from place to lace by a personland put into engagement with the work. The device is to be operated by means of an electric motor conveniently housed in its structure.
With the above and numerous other objectsin view as will appear as the description progresses, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing:
Figure 1 is a side elevation of the sander embodying my invention,
Figure 2 is a vertical section taken therethrough,
Figure 3 is a horizontal section taken substantially on the line 3-3 of Figure 1 looking downwardly,
Figure 4 is a vertical section taken transversely through the device and substantially on the line 4-4 of Figure 2,
Figure -5 is a fragmentary top plan view of the pressing device, l
Figure 6 is a fragmentary side elevation thereof, and
Figure 7 is an enlarged detail sectional view showing the manner in which the brusher is carried by the frame.
4 Referring to the drawing indetail it will be seen that the frame A of the sander is constructed with a body or upper plate 1 attached to which are the sides 2 which depend therefrom. These sides are provided with extensions 3 connected by handle 4 of the plate 1, in order that-the same may be grasped in the hand. A shaft 6, which is the shaft of an electric motor 7 is journaled in the side members 2 of the frame, and a roller 12 is rotatably mounted between the said side members 2 and is driven from'the shaft 6 through the medium of any suitable system of gearing indicated' in general by the numeral 13, the roller 12 being covered by fricv tion material such as rubber, as indicated by the numeral 17 An idle roller 18 is journaled on an axle 19 and is also covered with a sheet of frictional material 17. This idle roller 18 is mounted on the axle 19 by means of bearings 20. The axle 19 extends through openings 21 in the sides of the frame. On each side of each opening there is provided an ear through which is threaded a screw 24. These screws engage the sides of the ends of the axle and by proper adjustment the distance of idle roller 18 from the driven roller 12 may be varied for tensioning the belt sander 25 trained thereover.
e A presser casin 26 is movable between the lower portions o the sides 2 and the rollers 12 and 18. This casing is provided with threaded apertured extensions 28. 'Ihe sides 2 are provided with inwardly extending pro- Jections 29 located above the apertures in extensions 28. Thumb screws 30 are threaded through the extensions 28. Springs 31 are disposed about these screws 30 between the extensions 28 and rejections 29 of the sides 2 so as to normallylliold them separated from one another, the limit of this separation being controlled by the screws()` v This presser casing 26 has disposed thereabout across its bottom a Brussels carpet strip 32 held in place by plates 33. At the ends of this casing there are provided grooves for receiving vertically disposed` ribs 34 on the rial such as rubber and are of suliicient length to extend a little below the belt as is illustrated clearly in Figure 2. Thus when the belt is engaged with'the work the studs are ,engaged with the support upon which the work is located and prevent the sander from movement while it is being held in engagement with the work. In some cases it is evident that these studs will engage the work itself when it is of a broad nature. I have also found that this device may be inverted and the handle 5 held in a vice and the work applied to the rim of the belt sander.
While the preferred embodiment of my invention has been described in detail, it will be understood that I do not wish to be limited to the particular constructionset forth, since various changes in the form, materials, pro Ortions, and arrangement ofarts, and in the details of construction may e resorted to without departing from the spirit and scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is:
l A device of the class described including a frame,.a pair of rollers journaled in the frame, a belt sander trained over the rollers, means for rotatinv one of the rollers, and a series of exible rictional studs positioned at the sides of and depending below the active run of the belt sender.
In testimony whereof I affix my signaturel HAROLD A.. SWAN.
