' 4 Claims. (Cl; 51170) This inventionrel'ates to certain new and us'efulimprovements in electric sanders and, morpar'ticularly, to
' a sander attachment which is adapted to fit in an electric Patented Aug. 26, 1958 7. its upper end with, a straight-sided socket 16. The other an electric drill, which attachment, together with the electric drill, will function as an electric sanding machine.
It is another object of the present invention to provide a sander of the type stated which canbe readilyand conveniently mounted, as an attachment, upon a portable electric drill or similar power handtool in a simple and secure manner.
It is an additional object ofthe'present invention to provide a sender attachment "which, when operatively mounted upon an electric drill, 'Will be positioned at a comfortable angle for the user.
It is a further object of the present invention to provide a sander of the type stated having a simple,'e fiicient driving and transmission mechanism.
It is also an object of the present'inventiontoprovide a sander of the type stated having novel and efiective means for holding sandpaper tightly inoperative position and quickly releasing same forreplacem'entwh'en necessary.
With the above and other objects in view, my invention resides in the novelfeatures of form, 'coiis'truction,-"arrangernent, and combination of part presently described and pointed out 'inthe claims.
In the accompanying drawings Fig. l is a perspective view of a sander attachment constructed in accordance 'with"'a'n'd' embodyingthepre'sent invention; 7

Figs; 5, 6, '7,and 8'-are"diagramn1'atic viewsbfthe sander platen in four different positions illustrative of its path of movement in completing a full sanding stroke.
Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of the present invention, A designates a sander attachment provided with a body casting 1 having spaced parallel end walls 2, 3, and spaced parallel side walls 4, 5, these four walls being integrally joined along their upper edges with a top wall 6 to form an open-bottomed chamber c. The top wall 6, furthermore, integrally includes an inclined portion 7 and a flat portion 8, the latter being substantially parallel to the plane of the open bottom of the chamber 0, as can best be seen in Fig. 3.
The body casting 1 is further provided along its inclined wall portion 7 with a recess 9 having a bottom wall It and a somewhat elliptical side wall 11 for accommodating two meshing bevel gears 12, 13. The gear 12 is axially bored and tapped on its under face for receiving the threaded end of a headed stud 12A which is jourgear 13 is provided with a downwardly projecting hub 17 which is also journaled in and extends through a boss 18 formed in the bottom wall 10 of the recess 9. As may be seen in Fig. 3, the bosses 18, 14, are so positioned that the axis of the hub 17 is vertical when the sander A is in operative position, and, similarly, the axis of the hub 15 is perpendicular to the wall portion 7. The top of the recess 9 is covered by a closure plate 19 which is secured to the body casting 1 by screws 20 and has a clearance aperture 21 adapted to fit loosely around the hub 15.
The hub 17 is axially bored and threaded therein is a stub shaft 22 formed integrally as a part of an eccentric 23 which includes radially projecting flange 24 having a counterweight 24' and a downwardly projecting offcenter shaft 25.
Adjacent to its four corners, the top wall 6 of the body casting 1 is provided with four symmetrically located apertures 26 adapted for accommodating four screws 27 which engage in corresponding internally threaded inserts 28 respectively molded in the upper end of rod-like rubber mounting posts 29. At their lower ends, the posts 29 are also provided with internally threaded inserts 38 for engagement with screws 31 which extend through correspondingapertures 32 located in the four corners of a rectangular platen 33. The platen 33 is essentially rec- 'tilinear in shape having upwardly extending longitudinal flanges 34, 34', provided with elongated slots 35, 36, and
" recesses 39, 39.
The platen 33 is further provided with'a centrally located circular socket 40 provided with a platen bearing 41 having a centrally bored aperture 42 for operative engagement with the off-center shaft 25 of the eccentric 23. Adhesively secured upon the flat'under face of the platen 33 is' a thick'rubber sheeting pad 43.
Loosely disposed through the slots'35, 35, and 36, 36, respectively, are U-shaped wire bails 44, 44', resiliently connected by springs 45, 46, and being rotatably attached at their external ends to knurled rod-like rollers 47, 4-7,
" which respectively fit in the grooves 38, 38.
"The' sander attachment A is further provided with an 5 upstanding mounting bracket 48 which is demountably secured to the body casting 1 byform- fitting flanges 49, 50, which conform to the longitudinal margins of the wall portion 7, said flanges 49, 50, being provided with centrally located slots 51, 52, for accommodating screws 53, 54, which are threaded into corresponding threaded apertures 55, 56. The mounting bracket 4-8 is further provided with a channel-forming bight-portion 57 for slidably accommodating an upstanding attachment arm 58 and is provided at its lower end with a longitudinally extending slot 59 adapted to receive a headed screw 6% which extends through an aperture 61 in the bight-portio-n 57 and is engaged by a tubular nut 62. It should be noted that the nut 62 is integrally provided with an externally threaded shank 63 for engagement with a threaded aperture 64 formed in a plastic handle 65. Outwardly with respect to the slot 59, the attachment arm 58 is provided on its longitudinal walls with two opposite, parallel, longitudinally extending slots 66, 67, for accommodating a clamping band 68 which passes around a drill ment in the drill chuck 71 and a fiat-sided bit 72 for snugfitting engagement in the socket 16 of the hub 15.
In use, the sander attachment A is secured to the drill D by the clamping band 68 and by adjusting the attachment arm 58. When the drill is energized, the adapter 69 will rotate the hub 15 rotating the gear 12, which, in turn, rotates the gear 13 and the eccentric 23, thereby causing the platen 33 to circulate around a path as illustrated by Figs. 5, 6, 7, and 8, being resiliently supported at all times by the posts 29.
A rectangular sheet of sandpaper S can be placedflatwise upon the downwardly presented face of the rubber pad 43 with the knurled rods 47, 47', in released position hanging loosely below the platen 33. Thereupon, first one of the rollers 47, 47', is swung upwardly and into its associated groove and then the other is likewise swung upwardly. As this is done, the rollers 47, 47', roll over the sandpaper S, drawing it snugly and tightly into operative position. Preferably, the piece of sandpaper is cut to a slightly greater length than is required to fit between the grooves 48, 48', and, therefore, a short free portion will project upwardly beyond at least one of the rollers 47, 47'. The piece of sandpaper S can thus be very quickly released merely by pulling outwardly and downwardly on such free portion.
It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the electric sander may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent is: p
1. In a sander, a platen having upstanding parallel side-flanges and upstanding parallel end-flanges, said sideflanges being provided with elongated slots and said endfianges being provided with outwardly presented recesses, U-shaped bails slidably mounted in the slots and extending outwardly therefrom along the sides of the platen, each of said bails being provided at its outer end with a roller adapted to fit within one of said recesses, and spring means for biasing the bails inwardly with respect to the end-flanges.
