FRANK o. WILKING, or INDIANAPOLIS, INDIANA.
NEEDLE-TRIMMER non TALKING-MACHINES...
To all whom it" may concern:
Be it known that I, FRANK O. WILKING, a citizen of the United States, and a resident of Indianapolis, county of Marion and State of Indiana, have invented a certain new and useful Needle-Trimmer for Talking-Machines; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, in which ters refer to like parts.
The object of this invention is to trim the wooden needles in talking machines more satisfactorily than has been done heretofore;
like letthat is, to enable the needle to be cutor' shaved thinner so as to'get about double the number of cuttings as compared with devices heretofore in use, and to trim the needle without removing it from the sound box on which it is mounted, and to self sharpen the cutter or trimmer.
A feature of this invention is in making a cutter formed like a pair of shears, that is two members pivoted together, with the sides of their heads in slidable engagement with each other as the device is operated. One member carries a rigid guide or'holder for the needle while the other member carries a stop for the needle and acircular cutter which gives to the needle a shearing cut. This circular cutter is spring pressed against the face of the member carrying the needle guide or holder so that it will make a fine shaving out and also will be self sharpenmg. g Y
The full nature of the invention will be understood from the accompanying drawings and the following description and claims.
In the drawings, Figure 1 is a side elevation of the needle trimmer with the needle and needle holder of the sound box in pl'ace, the device being shown in condition for operation. Fig. 2 is an edge-view of'what is shown'in Fig. 1. Fig.3 is the-same as Fig. 1 with the'parts in operated position, the lower partbeing broken a-way. Fig. 4'
is a perspective view ofthe needle. Fig. 5
Specification of Letters Patent. t m 1 ,1918. Application filed October 22,1917. Serial No. 197,850,
member in Fig. 6, that is, with the two members in position before they are actuated, the lower part of the device being broken away.
The sound box of the talkingmachine is not herein shown, but the needle holder 10 of the sound box is shown. That holder is tubular to receive the wooden needle 11 which is secured in place by a set screw 12.
This structure and the needle areof com-' mon type heretofore in use.
The needle trimmer is formed of ameni- "ber 15 which carries a cutter 16' and amember 17 which carries a needle guide or holder 18, said two members 16 and 17 being shaped like scissors or nippers with their heads overlapping so that the sides of them abut not being used,'isshown in Fig. 1, while the limit during. use is shown in Fig. 3.
The cutter 16 is a disk with a sharp circu lar cutting edge at one side face of the disk,-
which side face and" cutting edge bear tightly against the inner side face of the head of the member 17 which carries the" needle guide or holder. The cutter 16 has a hub 25 which is mounted rotatably in a circular .recess 26 in the member 15 and there is a spiral spring 27 in said recess ,which always forces the cutter outward against the other member 17 of the trimmer. The needle guide 18 is secured rigidly in the head of the member 17 at an inclination, as shown in Fig. 6, and it has in its periphery a longitudinal needle groove 28,.
angular transversely so as to fit onor across the needle and to present the end of the needle to the cutter 16 at, the proper angle with reference to said vcutter to cause the end of the needle to receive, when trimmed, v
the proper bevel, substantially as shownfij A stop shoulder 29 is located in the head of y the member 15 opposite the inner end of the needle groove 28 to limit the position of the inner end of the needle when the trim- 'ming tool is placed in connection with the I needle, or when the, needle is placed in the will be out off from the end of the needle. And said shoulder 29 is immediately in advance of the cuttingedge 0f thecutter, 16...
so that as the device is operated, the shoulder 29 will leave the inner end of the needle while the device is operated. Buthere the.
needle istrimmed in another manner, by applying the trimmer to the needle while 1t is still secured 'to the sound box. This makes v, it needless to remove the. needle from the" p In this latter manner the sound boX is thrown. up in idle soundbox for trimming.
position, as is well. understood, and that exposes the needle and makes it easy to apply thetool thereto, The tool is applied by holding it in one hand and placing theguide 18. against the underside of the needle; When that "happens, the. stop shoulder 29.
' The trimmer is then held in such relation to the.
abuts again'st the end of the. needle.
needle while it is operated and it is operated bymoving the two handles ofthe device toward each other. That moves the cutter 16 across the inner face of the member 17 and into cutting engagement with the innerend of the needleand as the cutter advances, the i stop shoulder 29, of, course,' moves ,away
from the needleas the cutter and stop shoul der are securedto thesame member 15'. The I,
cutter is so mounted with relation tothe needlegnide18 thatthe edge thereof below a transverse radius would engage the needle, I which will automatically turn somewhat or roll'and give to the needle the shearing cut desired. A very fine shaving. out can be given because thespring 27 presses the cut ting, edge of the cutter tightly against the inner ,face of the member 17 and such inner. 1 face: of the member 17 sharpens such cutting edgeg so that it will continue ,to lie flatly. against such inner face of the memb en 17; Thisandjthe automatic turning of the cut- A I shear-like, a needle guide secured in nthe heretofore known, which 4 doubles the length of the life-or use of a needle.
