6 Claims.
1 This invention relates to surface dressing machines adapted to be used for sanding and polishing wooden floors, stair treads, risers, and similar surfaces.
Heretofore the devices commonly used for finishing surfaces such as floors, and the like, usually comprised, as essential parts, a sanding disc and electric motor for rotating the same.
However, such machines, in most instances, were constructed and arranged so that it was not possible to apply the abrasive disc to certain surfaces such, for example, as the portions of the floor under radiators, and with those machines which were specially designed for the purpose of getting under radiators and in other confined spaces, it was not possible to handle the same expeditiously and conveniently and to properly apply the necessary pressure when one of the -machines was being used upon the ordinary expanse of the floor.
The principal object of the present invention is to provide a machine for finishing surfaces having a novel arrangement of parts and which is so constructed and arranged as to facilitate the operations and extend the scope of usefulness thereof.
A further object of the invention is to provide a machine of the character aforesaid the parts of which may be readily and quickly shifted to permit the convenient use of the same under varying conditions.
The nature and characteristic features of the present invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:
Figure 1 a top or plan view of a surface dressing machine embodying the main features of the present invention;
Fig. 2 is a vertical section thereof, taken on the line 2-2 of Fig. 1, the motor however being shown in elevation;
Fig. 3 is an underneath plan view of the machine; and
Fig. 4 is a transverse section taken approxim? tely on the line 44 of Fig. 1.
It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed -fwithout departing from the spirit of the invention.
Referring to the drawings, in the particular embodiment of the invention therein shown, it) is an electric motor, of any preferred type, pro- 2 vided with a main handle H projecting at right angles to the axis of the motor if! and through which handle the lead-in wires !2 extend.
The motor Ii! may also be provided with an auxiliary handle 13 which is adapted to be alternatively mounted on either side of the motor housing as may be desired, but in either event extending at a right angle to the handle I l and in the same or a parallel plane.
The housing of the motor Iil is provided with an extension !4 in which the reduction gearing (not shown) may be enclosed, and from which an operating shaft [5 extends downwardly. A pulley I6 is mounted on the lower end of the shaft I5.
The lower end of the extension IA of the housing of the motor ID is provided with an annular flange l! which rests upon the top surface of a casing [8 which projects outwardly therefrom.
A plate member l9 having an annular recess 20 therein engages the flange ll of the extension I 4 of the housing of the motor it. The plate member If! is secured to the casing it by means of bolts 2|, 22, and 23, which extend through elongated slots 24, 25, and 26, respectively, in the casing la. The bolts 2! and 22 are threaded into angle members 2i having vertical extensions 28 which engage the inner faces of the side walls 29 of the casing I 3.
The bolt 23, which is arranged at the central rear portion of the casing I8 is secured by means of an ordinary nut 34 threaded on said bolt 23.
The plate member [9 which serves to confine the flange ll of the extension M of the housing of the motor In is also provided at the two rear corners with casters 31} secured at their respective locations by nuts 3| threaded on the shank portions 3?. of the casters 30.
At the forward end of the extending casing !8 there is mounted an auxiliary casing 35 in which the abrasive disc and the associated parts are rotatably mounted.
Secured to the auxiliary casing 35 is a cup member 36 which serves to support the outer ring 31 of a ball bearing. The inner ring 38 of the ball bearing is mounted on a stud shaft 46, the free end of which has a metallic disc 41 threaded thereon.
The disc ll has a rubber facing member 42 upon which the abrasive disc 43 is mounted. The abrasive disc 43 is of the usual type, being made of paper or cloth with a granular abrasive secured on its face, and the same is secured to the rubber faced metallic disc 4! by means of a nut 44 threaded on the stud shaft 46.
Secured to a portion of the supporting disc 4| is an annular member 45 suitably shaped to provide, in conjunction with a suitably shaped face portion of the disc 4|, an annular channel 46 in which the belt 41 travels to rotate the abrasive disc 43 and its associated parts. The belt 4'! is driven by the pulley IE on the shaft l5 which is operated by the motor 10.
The bolts 2!, 22 and 23 are ordinarily of such tension that the casing l8 and the parts carried thereby may be swung with a certain degree of frictional restraint, about the axis of the shaft [5, whereby the main handle II which is secured to the motor housing, may be disposed at any desired angular position with respect to the extending casing I8.
When, however, it is desired to lock the handle I l, as well as the auxiliary handle l3, in any desired adjusted position this may be accomplished by tightening the bolts 2!, 22 and 23 sufiiciently to securely clamp the flange H.
The arrangement is also such that, by loosening the bolts 2!, 22 and 23 sufiiciently, the casing 18 may be shifted longitudinally with respect to the motor !0 and its associated parts, including the pulley it, to take up any slack in the belt which may be necessary to cause the abrasive disc to be rotated efliciently.
It will be seen that there is thus provided a surface dressing machine in which by a relatively simple arrangement the abrasive mechanism proper may be swung to any desired position with respect to the main handle of the motor, thereby greatly extending the usefulness of the tool.
It will also be noted that the arrangement is such that the proper belt tension may be readily obtained by the mere longitudinal shifting of the extending casing with respect to the motor and its associated parts, and this may be controlled by the same means which control the shiftability of the handle with respect to the extending casing in which the abrasive disc and its associated parts are mounted.
I claim:
1. A surface dressing machine comprising an electric motor, a handle fixedly secured to and extending outwardly from the side thereof, a relatively low extending casing, mean for rotatably securing a portion of the motor to one end of said extending casing whereby the handle carried by the motor may be brought to desired angular relationship with respect to said casing, an abrasive disc journalled at the other end of said casing, and driving means operated by the motor for rotating said abrasive disc.
2. A surface dressing machine comprising an electric motor, a handle fixedly secured to and extending outwardly from the side thereof, the motor having a housing with a portion provided with an annular flange, a relatively low extending casing, means for securing the annular flange of the motor housing to one end of said extending casing whereby the motor handle carried by the motor may be brought to desired angular relationship with respect to said casing, an abrasive disc journalled at the other end of said casing, and driving means operated by the motor for rotating said abrasive disc.
