MAGNETIC PICKUP FOR STRINGED MUSICAL. INSTRUMENTS Filed NOV. 2, 1948 Patented Sept. 11, 1951 MAGNETIC PICKUP FOR' STRINGED MUSICAL INSTRUMENTS Theodore M. McCarty, Kalamazoo, Mich., as-
signor to Gibson, Incorporated, Kalamazoo, Mich., a corporation of Michigan Application November 2, 1948, Serial No. 57,987
- 13 Claims.
This invention relates to improvements in magnetic pickups for stringed musical instruments.
The principal objects of this invention are:
First, to provide a combined finger rest and magnetic pickup for stringed musical instruments.
Second, to provide a mounting for a magnetic pickup for a stringed musical instrument which will not change the natural tone quality of the instrument or require alteration of the instrument in any way.
Third, to provide a combined magnetic pickup and finger rest which does not interfere with the playing of the instrument.
Fourth, to provide a magnetic pickup which can be used in connection with conventional finger rest on stringed instruments Without altering the tone of the instrument.
Other objects and advantages relating to details of the pickup will be apparent from a consideration of the following description and claims.
The drawings, of which there is one sheet, illustrate a preferred form of a combined finger rest and pickup and one form of a separate pickup without a finger rest.
Fig. 1 is a perspective view of a guitar with the combined nger rest and magnetic pickup operatively mounted thereon.
Fig. 2 is a plan view of the under side of the finger rest and pickup.
Fig. 3 is a fragmentary cross sectional view taken along the plane indicated by the line 3-3 in Fig. 1.
Fig. 4 is a fragmentary plan view of a guitar with a pickup mounted thereon independently of any finger rest.
Fig. 5 is a fragmentary cross sectional view taken along the plane of the line 5-5 in Fig. 4.
The drawings illustrate a guitar I which is conventional in all respects, being provided with the usual rim 2, top 3, neck 4 and strings 5. The strings 5 are drawn tightly across a bridge 6 and the instrument is arranged to be played in the usual fashion.
The combined nger rest and magnetic pickup, generally indicated at 1, is mounted over one side of the top panel 3 and has a longitudinally extending inner edge 8 positioned along the side of the strings. The outer edge of the finger rest is irregularly curved, as at 9, in a well known manner to provide support for the musicians fingers and to act as a pick guard. The finger rest is preferably made of synthetic plastic material but other rigid materials could be substi. tuted therefor.
Intermediate of the longitudinal inner edge 8 of the finger rest there is provided a lateral extension I0 which projects underneath the strings 5 in spaced relationship between the strings and the top panel 3. Secured to the under side of the extension I0 is a housing Il of soft iron which encloses and secures a magnetic pickup mechanism I2 to the under side of the extension. The pickup mechanism consists of a coil of fine wire I3 wound around a plurality of short cylindrical magnets I4 which project upwardly through the extension and underneath each of the strings 5. The soft iron housing acts both as an enclosure for the coil and magnets and also acts as a core element in that it forms part of the circuit for the magnetic fields of the magnets. This permits the pickup to be thin enough to fit between the strings and the top of the guitar. v
As is most clearly illustrated in Figs. 1 and 2 the coil I3 is electrically connected through the cable I5 to a volume control switch I6 and a tone control switch Il. A condenser associated with the tone control is indicated at I8. The cable I5 terminates in a jack I9 arranged to receive the plug and of a cord 20 for connecting the pickup to amplifying and sound producing mechanism. The magnetic pickup mechanism operates in a manner well known to persons skilled in the art and so is notl Vdescribed in greater detail.
The under side of the finger rest 'I is provided with reinforcing strips 2| along its longitudinal edges 8 and is further provided with a supporting foot 22 which projects downwardly from the upper end of the rest and is arranged to seat against the top 3 adjacent to the rim 2 so as not to alter the tone quality of the instrument. Toward its lower and outer edge the rest 'I is provided with an attaching boss 23 apertured to receive the upper end of a clamp 24. The clamp 24 extends along the side of the guitar to the back thereof and is adapted to clampingly support the lower end of the finger rest from the side of the guitar in spaced relationship to the top of the guitar.
Attention is particularly called to the fact that the combined pickup and nger rest is supported in spaced relationship with the top of the guitar and the strings so Ythat the natural tone qualities of the guitar are not altered by the pickup. If desired, the cable 20 can be disconnected from the jack so that the guitar may be played in the normal fashion without amplification. The
volume and tone controls are conveniently located where they can be adjusted according to the desires of the musician when the magnetic pickup is being used. While the drawings illustrate a guitar it will be appreciated that the rest and pickup can be easily adapted for use on other stringed instruments such as mandolins, banjos, etc.
Figure 4 illustrates a modified form of the pickup which can be used either alone or in combina tion with a separate finger rest. The support panel 25 is smaller than the :lingerl rest 'I terminating along the lower edge of the extension 26. The extension 26 terminates closely adjacent to the last string of the instrument but carries the magnetic pickup mechanism and magnets Hl in much the same manner as the combined pickup and nger rest. Control knobs I6 and I1 and jack I 9 are mounted on the panel 25 as in the combined form of the pickup.
The panel 25 extends to the upper end of the body of the guitar and is provided with a supporting block 22. A pin 21 extends from the foot into the side of a portion of the guitar rigidly connected to the finger board 23 to hold the panel in spaced relationship to the top of the guitar. The lower portion of the under side of the panel carries a block 23 which connects to the clamp 24. As is most clearly shown in Fig. the clampv 24 comprises a U-shaped rod-like member having an-oifset or shoulder 2g in the upper leg thereof. rIhe shoulder 29' seats against the rim of the guitar and may have a screw 39 passed therethrough if the pickup is to be attached more or less permanently to the guitar. A thumb screwY 2| threaded through the lower leg of the clamp permits the clamp to be tightened on guitars of different thickness. The panel is thus supported clear of the top panel of the guitar so as not to alter the natural tone of the guitar.
Either of the pickups shown can of course be made for right or left handed musicians and it will be noted that the pickup shown in Fig. 4 can be used in conjunction with an ordinary nger rest such as is indicated by the dotted lines at 32. As thus arranged, the guitar would normally be played by a left handed musician.
