' SANDING MACHINE.
1 Application filed July 27, 1925. Serial No. 46,447.
This invention relates to apparatus used for sanding wooden mouldings and the like, and the object of my invention is to devise a machine with which may be employed a reverse of the pattern of the moulding for forcing the sanding surface into the hollows or grooves of the mould and which will not damage in any way sharp edges which appear in certain mouldings.
Another object is to arrange said apparatus so that the wear, when operating on a narrow moulding, is spread over a large area of the sanding surface, andthus reduce the liability of scorching which is likely to occur if the same part of the sanding surface is continually applied to the moulding.
Further objects of my invention will here-v w inafter appear.
I attain my objects by means of the constructions hereinafter described and illus trated in the accompanying drawings in which Fig. 1 is a plan view of my improved apparatus; N
Fig. 2 a side elevation of the same; i
Fig. 3 a rear elevation of the'same; and
Fig. ,4 a front elevation of the same.
In the drawings like numerals of reference indicate corresponding parts in the dif ferent figures. I o
1 is a frame which maybe of any suitable shape and size to support the variousparts. At one end of this frame is journalled in suitable bearings the main drive shaft 2. Also journalled in suitable bearings adjacent the shaft 2 and driven therefrom by suitable bevel gears 3 is the vertical shaft l.' On the upper end of this shaft and rotatable therewith is a drum 5. This drum, for, a purpose which will hereinafter appear, is lagged with a thick ply of soft rubber or similar material.
At the opposite end of the frame a guide 6 is formed on which is slidable the member 7 in which is j ournalled a second vertical shaft 8, which carries a drum 9. For the purpose of moving the member 7 along the guide a threaded member 10 is j ournalled in the guide 6, which threaded member passes through a nut or projection 11 on the member 7. A clamping screw 12 is threaded through the member 7 adapted to engage the guide to lock the member 7 as adjusted.
Intermediate the drums 5 and 9 and at one side of the frame is mounted an oscillating idler drum 13. This drum is journalled in a bracket 14, which is pivoted on a bracket 15 secured to the frame. fFor the purpose of oscillating the drum-carrying bracket 14, I secure to this bracket one end of a rod 16. This rod is preferably divided, and the parts connected by a turnbuckle. The other end of this rod 16 is connected to an arm or crankon the upper end of a vertical shaft17, which is also driven by suitable gearing 18 fromthe main drive shaft 2. In order that the extent of oscillation of the bracket 14: may be varied, the crank on the shaft 17 is soarranged that the rod 16 may be connected therewith at various distances fromthe ELXlSOIl which it rotatcs. For supporting the moulding to be sanded, I provide a table 19. It is desirable that this table be adjustable both vertically and horizontally relative to the drum 9. At each side of the, frame'l are formed guides 20 on which are slidable members 21 to which one end of the table is pivotally connected.
Clamping screws'36 are provided for locking the members 21 in position as adjusted. The other end-of the table is pivotally supported on vertically adjustable members 22 which are slidable on the members 23, the latter being pivoted on a bracket 24 supported on the frame 1. It will thus be seen that the distance of the table 19 from the drum 9 may be varied by simply loosening the clamping screws 36 and moving the members 21 along the guides as desired," and again tightening the clamping screws, while the angle of the table to the drum may be varied by moving themembers 22 up or downrelative to the members 23.
A sanding belt 25 is mounted'on the drums 5, '9 and 13. This belt will be of ordinary construction, usually being provided with a cotton back. On the drum 9 is positioned a reverse 9 of the pattern of the moulding tobesanded, and the table 19 will be set at the proper distance from and proper angle to the drum 9 to suit the particular moulding. The moulding to be sanded will be fed across the table transversely of the frame with its moulded surface in engagement with the sanding belt as the latter passes over the reverse of the pattern carried by the drum 9.
To hold the moulding down in position on the table, I provide the spring pressed roller 26 which is carried by an arm 27 ivoted on a support 28 mounted on the ta 1e. To hold the roller in position on the mouldin g, I connect to the arm 27 a rod 29 onwhich is mounted a spring 30 which engages the this rod 29 is connected to a nut 31slidab1e in a slot formed in the support 28.
" ing the moulding will be greatly increased,
As the sanding belt is driven by the drum 5, the drum 13 will also be oscillated, and as the belt passes over this oscillating drum it will moved up and down, and will also move up and down on the drum 9, as shown in Fig. 2, so that the area of the belt engagthus increasing the life of the belt as well as reducing the tendencyto scorch. The surface of the drum 13 will be provided with a s'uitablecovering to prevent slipping of the belt, As the belt passes overthe reverse of the moulding, which forms a projection on thesurface of the drum 9, the resllient surface of the drum 5 will give sufficiently-to compensate for the pull on the belt as it is drawn over the reverse of the pattern, and
the tendency to stretch or tear the belt is therefore greatly reduced.
From the above description it will be seen that I have devised a construction which will satisfactorily attain the objects of my invention as set out in the preamble of this specification.
WVhat' I claim is:
1. In sanding apparatus, the combination of a pair of spaced rotatably mounted beltsupporting members; an endless sanding belt carried by said members; means for causing a transverse movement of said belt as it trav els around said members comprlsing a th1rd "member around which the belt passes; a
. tern of the material being sanded, said belt being materially wider than the-reverse of' the pattern and materially narrower than To hold the moulding against the belt carrying members; and means for causing a transverse movement of said belt as'it travels around said members.
3. In sanding apparatus, thecombination of a frame; a pair of spaced rotatably mounted belt-carrying members; an endless sanding beltcarried by said members, one of said members having a"reverse of the pattern of the material being sanded, the other of said members having a belt-engaging surface of resilient material of a thickness to compensate for irregularities in the surface of the reve'rse'ofthe pattern, said belt being materially wider than the reverse of the attern and materially narrower than the elt carrying members; and means for causing a transverse movement of said belt as it travels aroundsaid members.
4;. In sanding apparatus, the combination of a frame; a pair of spaced rotatably mounted belt-carrying members; an endless sandmg belt carried by said members, one of said members having av reverse of thepatbeing materially wider than the reverse of the pattern and materially narrower than the belt carrying members; a third member around which the belt passes; a pivotally mounted. support for said third member; and means for oscillating said support.
5. In sanding apparatus, the combination rod; and means for rotating said crank arm.
6. In sanding apparatus, the combination item of the material being sanded, said belt of a pair of spaced rotatably mounted beltsupporting members; an endless sanding belt carried by said members; means for causing a transverse movement' of said belt as it travels around said members, comprising a third member around which the belt passes; a pivotally mounted support for said third member;,and means for automatically os'cil latingsaid support. q
