Bay, Denver, 0010. Application May 18, 1945, Serial No. 594,437 2 Claims. 1 (Cl. 51—186) 2 and 8 are mounted, the lower roller 8 being This invention relates to a reed sander and it is formed of metal, or other suitable material, and one object to provide a device by use of which constituting a pressure roller carried by‘ a pin or reeds of musical instruments may be sanded to axle 9 and the upper roller being a sanding roller smooth them and reduce them to the correct thickness. UK and carried by a bolt or axle ID. The upper roller is formed as shown in Figure 5, and referring to Another object of the invention is to provide this ?gure it will be seen that it has an elastic a sander which may be readily held in a person's body or roller proper ll formed with a bore hand between the thumb and ?rst ?nger and snugly receiving the bolt Ill but loose enough to pressure applied to cause sanding of a reed en gaged between rollers at ends of resilient arms 10 permit the roller to be turned about the bolt or axle when necessary. A sleeve l2 formed of of the device. sand paper ?ts snugly about the elastic roller l0 Another object of the invention is to provide a and when the nut I3 is tightened and the ears 6 sander wherein one arm thereof carries a pres of the upper arm 2 are forced towards each other sure roller and the other a sanding roller which is formed of elastic material and mounted about 15 into pressing engagement with ends of the roll er, the roller will be expanded diametrically as a bolt or pin carrying a thumb but which, when well as compressed longitudinally and caused to tightened, causes the elastic roller to be ex have tight binding ?t within the sand paper panded to frictional gripping contact with a sleeve of sand paper about it to prevent rotation sleeve l2. Therefore the sleeve will be prevented of the sleeve about the roller, tightening of the 20 from turning about the elastic roller and the nut also serving to prevent free rotation of the roller itself will be prevented from turning about roller about the bolt during use of the sander. the bolt by frictional binding action. Near its Another object of the invention is to provide a head M the bolt in is formed with a squared sander which is quite small and may be carried portion [5 ?tting within a squared opening [6 in a pocket when not in use. The invention is illustrated in the accompany ing drawing wherein: 25 formed in the ear through which it passes and this squared portion prevents the bolt from turn ing during use of the sander as well as allowing Fig. 1 is a perspective view of the improved the nut to be tightened or loosened easily without sander. 30 the bolt turning with the nut. Fig. 2 is a front view thereof. During use of the sander it is held between Fig. 3 is a side view of the sander. the thumb and ?rst ?nger of a hand and the Fig. 4 is a view looking down upon the sander. portion of the reed I‘! to be sanded engaged be Fig. 5 is a sectional view taken longitudinally tween the rollers. Reciprocating movement is through the sanding roller. This sander is particularly adapted for sanding 35 imparted to the sander and as it is moved lon reeds of musical instruments but it is to be under gitudinally of the reed the roller 8 will force the stood that it may be put to other uses. The body reed against roller 1 but will turn so that this I of the sander is formed from a strip of resilient roller will move easily along the reed. The fact sheet material which may be sheet metal, plastic, that the roller 1 is prevented from turning about or other suitable material. The strip of resilient 40 the bolt It causes the sand paper sleeve to have sheet material is folded midway its length to rubbing contact with the reed. When a portion form arms having their rear ends connected by a of the sand paper sleeve in use becomes worn curved bridge portion 3 serving as a spring con the nut I3 is loosened, the rubber sleeve I I turned necting the arms and cut to provide an opening 4 for imparting added ?exibility to the bridge 45 a partial rotation about the |bolt to bring another portion of the sand paper into position opposite and permitting the arms 2 to be readily moved roller 8 and the nut again tightened to secure towards each other when pressure is applied by a roller ll against turning movement. After the thumb and fore?nger between which they are sand paper sleeve [2 has been entirely worn be grasped during use of the sander. Depressions 5 are formed near front ends of the arms to re 50 yond further use the bolt is removed, the rubber roller removed from between ears of the upper ceive the thumb and the ?nger and prevent the device from slipping out of place between the thumb and the ?nger between which it is held. arm‘, the worn out sleeve l2 removed and a new one slipped into place, and the roller l I then re placed between the ears and the bolt thrust into Forward end portions of the arms are formed with ears or tongues 6 between which rollers 1 55 place and its nut applied and tightened. 2,408,953 4 Having thus described the invention, what is gagement with the bolt and the sleeve to prevent claimed is: 1. A sander, comprising a body formed from a turning of the elastic roller and the sleeve. 2. A sander comprising a body having arms strip of resilient; sheet material folded midway its length to form arms connected at their rear ends by a spring-forming bridge, front ends of the arms being formed with ears at opposite sides thereof, a pressure roller rotatably mounted be shiftable towards and away from each other and having bearings at their front ends,v a pressure tween the ears of one arm, an‘ elastic roller be roller rotatably mounted between the bearings of one arm, and a sanding roller between bear ings of the other arm including a roller formed of elastic material and having a longitudinally tween the ears of the other arm, an abrading 10 extending bore, an abrasive sleeve ?tting snugly about said elastic roller, a bolt passing through sleeve ?tting snugly about said elastic roller, a the bore of said elastic roller and through the bolt passing through the elastic roller and the‘ bearings between which it is located and held ears between which it is located and having a against rotary movement, and a nut screwed up non-circular portion engaged through a similar ly shaped opening in one ear to prevent rotation 15 on said bolt and tightened to force the bearings through which the bolt passes into contact with of the bolt, and a nut carried by said bolt and‘ ends or the elastic roller to compress the‘ roller tightened to draw the ears between which the longitudinally and expand it diametrically into elastic roller is located towards each other and binding engagement with the bolt and the sleeve apply pressure to opposite ends of the elastic 20 and prevent turning of the elastic roller and the roller to compress the elastic roller longitudinal sleeve about the bolt.. ‘ ly and expand it diametrically for binding en JOSEPH E.
