SANDPAPERlNG-MACHINE.
SPECIFICATION forming part of Letters Patent No. 443,795, dated December 30, 1890.
Application filed September 18, 1889- $erial No. 324,335. (No model.)
T0 aZZ whom it may concern.-
Be it known that I, WATSON R. Roor, a citizen of the United States, residing at Canton, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sandpapering-Machines, of which the following is a specification.
My invention relates to improvements in sandpapering-machines; and the chief object of my invention is to adapt such machine for use in sandpapering carpenters rules.
In the accompanying drawings, Figure 1 is a front elevation of my machine. Fig. 2 is a plan view of the same, and Fig. 3 is a vertical section on line as 00 of Fig. 1.
Adesignates the frame of the machine, supported upon suitable legs B. At one end of the frame is the driving-shaft O, carrying driving-pulley D and crank a, to which is connected the pitmanb for driving the reciprocating carriage E. Upon the carriage E three drums 4 6 6 are mounted, the axles of which are provided with thumb-nuts '7, by means of which said drums may be loosened or held fast. On the lower part of the carriage under the drums 6 .6 there are two pads S 8 of rubber, cork, or other suitable material, and outside of said pads at the corners of the carriage I prefer to place friction-rollers 9, as shown in Fig. 1. Strips of sand-pa per 10 10 or equivalent abrading-strips have one end secured to each of the drums 6 6, the strips then passing down under the rollers 9 and pads 8 8 and then upward to the drum 4, the strips being of an indefinite length and their surplus wound either upon the drum 4 or upon the two drums 6 6, as may be desired. I11 thus passing up to the drum 4 I prefer to pass the strips 10 over the roller 11, Fig. 1, or other guide, to give proper direction to the strips and keep them from contacting with the drums 6 6. The pads 8 8 and the drums 6 6 are secured to blocks 12, that are fitted to slide vertically in dovetailed ways, (shown most clearly by the plan view, Fig. 2,) and are held downwardly against the stop 13, Fig. 3, by means of the springs 14*, whereby the pads are brought downward to a fixed point, and at the same time they are capable of yielding upwardly under an excess of pressure. The pads 8, it will be noticed, have their under faces in the same plane, but at some distance apart, the distance between them being governed by the length of the joints or 5 5 sections of the rule to be sandpapered, that distance being a little less than the length of one section. The movement of the carriage is a little less than the distance between the pads. 6o
Underneath the frame I secure a thin bracket 18, on the front of which I mount the slide 14, which slide has attached to its up-v per end a bed-15 for supporting the'rules. I also attach to this slide the adjustable crossarm 16, which is loosened and fastened by the set-screw 17. The bracket that supports this slide is so thin that the operator may place his legs on each side thereof and his knees under the cross-arm.
In operating my machine the operator, when the bed is down in the position shown in Figs. 1 and 3, places a rule thereon,as indicated by broken lines in Fig. l, the same being illustrated with the projecting knuckle-joint upwardly and placed in position for polishing the inside-that is, the side of the rule that is concealed when folded. The carriage .is represented in Fig. 1 as at the extreme lefthand end of its throw, so that the right-hand 8o pad has been brought into a position immediately over the rule at one side of the knuckle-joint. The operator lifts his knees to force the rule against the pads with such pressure as may be desired, according to the sharpness of the paper or abrading-strip, and holds it there as the carriage reciprocates to carry the pads over the rule on each side of the knuckle-joint, the pads alternately coming up to the side of said knuckle-joint and go then retreating therefrom to the outer ends of each section, but not far enough to have the pads slip off over the ends. The other side of the rule is polished in like manner, only the rule is placed the other side up,.with 5 the knuckle-joint in a recess in the bed. When the sand-paper or abrading strips become worn, the thumb-nuts 7 may be loosened and the drums 6 6 andetbe turned to unwind the strips from the drums 6 6 and then wind I00 them upon the drum 4, or vice versa, so as to bring a fresh portion of the strips under the pads, after which the thumbnuts may be tightened again to hold the strips in place.
I claim as my invention 1. The combination of the reciprocating 5 carriage, the two pads S S, the drums 6 6 and 4, and the two strips of abrading material, each having one end secured to one of the drums G 6 and the other end of both strips secured to the drum 4-, substantially as described, and 10 for the purpose specified.
2. The combination of the reciprocating, carriage carrying the abrading-strips, the Vertically-moving' slide 14:, mounted upon a thin bracket, and the adjustable cross-arm 16, secured to said slide, substantially as described, and for the purpose specified.
