v SANDING DEVICE FOR SCROLL AND FRETWORK.

Application filed June 12, 1922.

To all whom it may concern:

Be it known that 1, JOHN CLEGHORN MUN- DELL, a subject of the King of Great Britain, and a resident of the village of Elora, in the county of Wellington, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Sanding Devices for Scroll and Fretwork, of which the following is the specification.

My invention relates to improvements in sanding devices for scroll and fretwork and the object of the invention is to devise a simple, quick and efficient means which may be operated by power for sanding the opposing edges of narrow slit openings such as are formed in scroll, fretwork, and the like and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. 1 is a perspective view of my sanding device and fragmentary portion of scroll work to which my device is applied.

Fig. 2 is a plan view of my sanding device.

Fig. 3 is a sectional detail on line 33, Fig. 2.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates a base support adapted to be permanently secured to a bench or other supporting structure. 2 is a standard portion extending upward from the base 1 and from the upper end of which extends a horizontal arm 3. 4 is a plate of thin rigid material provided with a longitudinal slot 5 in proximity to its inner edge through which extends securing screws 6 into the arm 3. The plate 4 extends laterally from one side of the outer end of the arm 3 for a purpose which will hereinafter appear.

1* is a finger extending outward from the plate 4 and formed integral therewith and terminating at its outer end in a headv 7 forming a curved recess 8. 9 is a shaft journalled in the standard portion 2 on one end of which is secured a driving pulley 10 and on the opposite end a pulley 11. 12 is a belt formed of suitable flexible material and provided on its outer face with a sanding sur- Serial No. 567,868,

face formed of abrasive material such as the upper face of the plate 4 and finger 4 the forward portion passing through the notch 8 and returning horizontally against the lower face of the finger 4* and plate 1 over the pulley 15 and down and around the pulley 11.

The pulley 10 is driven from any suitable source so as to revolve the belt 12. The workman then takes the piece of fretwork or scroll work, such as indicated at 16 and passes the finger 48 through the slitted opening of the scroll work. The belt 12 is continuously driven from its source of power, the abrasive surface of the belt travelling in contact with the edge of the scroll work to be sanded, the workman turning the scroll work so that the edges of the work at each side of the slit opening are sanded evenly from end to end.

The screws 6 may be readily adjusted so as to take up any slack in the belt 7.

From this description it will be seen that I have devised a very simple device whereby scroll work may be easily, quickly and efficiently sanded with a minimum amount of labour and insuring that the work be done accurately.

What I claim as my invention is:

1. A sanding machine for scroll work and the like comprising a supporting structure,

a thin finger extending therefrom adapted to be inserted in the kerf of the scroll work, and means adapted to simultaneously engage the parallel opposing edges of the kerf totravel parallelly over the upper and lower face of the finger in contact therewith and work kerf.

2. A sanding machine for scroll work and the like comprising a supporting structure, a thin finger extending therefrom having a recessed outer end, a belt extending parallelly longitudinally and around the finger crosswise of the opposing edges of the scroll end through the aforesaid recess and having an abrasive outer surface, and means for causing the belt to travel thereover and adapteclto engage the opposing edges of the scroll vvork l re'r f. g i I, V

3. A sanding machine for scroll Work and the like comprising a supporting structure, of a thin finger"adj1istable longitudinally upon such structure and having a recessed outer end, a belt extending parallelly longitudinally and around'the finger end through the aforesaid recess and havingan abrasive outer surface, and means for causing the belt to travel thereover so as to engage the opposing edges of the scroll Work keri JOHN 'CLEGHORN MUNDELL.
