METALLIC STRINGED MUSICAL INSTRUMENTS Filed Jan. 9, 1957 M M 6 75 W INVENTO 7%60 dare /7 M 605 United States Patent Ofitice 3,069,954 METALLIC STRINGED MUSICAL INSTRUMENTS Seth E. Lover and Theodore M. McCarty, Kalamazoo, Mich, assignors to Gibson, Inc., Kalamazoo, Mich.

Filed Jan. 9, 1957, Ser. No. 633,264 6 Claims. (Cl. 84-114) This invention relates to improvements in metallic stringed musical instruments. The principal objects of this invention are:

First, to provide an instrument that is lighter and less expensive than similar instruments known theretofore.

Second, to provide an instrument that does not require a case or body of suflicient weight and strength to Withstand the tension force created in the strings of the instrument.

Third, to provide a string support and electrical pickup that can be manufactured 'as a unit and assembled singly or in multiples as desired into musical ins-trum ents having variable musical properties.

Fourth, to provide a musical instrument in which a hollow tubular base forms the structural support and section, of a multiple unit stringed musical instrument embodying the invention, the break-out showing the connection between units.

FIG. 2 is a fragmentary vertical longitudinal cross sectional view through-an instrument which may be either a single or multiple unit instrument, the view being taken along the general plane of the line 22 in FIG. 4 with portions further broken away to the central longitudinal plane of the string unit to show the connections of the string unit to its supporting case.

FIG. 3 is a bottom plan view, partially broken away in section of one form of the string unit of the instrument with tone control, volume, and unit selector switches as shown at the bottom of FIG. 1.

FIG. 4 is an enlarged transverse fragmentary cross sectional view taken along the plane of the line 4-4 in FIG. 2.

FIG. 5 is a fragmentary side elevational view of a modified. form of the string unit of the instrument.

FIG. 6 is a fragmentary vertical transverse cross sectional view taken along the plane of the line 6-6 in FIGS. 1 and 2 and illustrating the connection between the peg head and base of the string unit.

As stated in the objects of the invention, the instrument is capable of selective combination in plural sections and includes a case or body built in sections 1A and 1B provided with holes 2 in the sides so that the cases can be bolted together as at 3 in FIG. 1. The sections IA'and 1B of the case consist of side panels 4, end walls 5 and top panels 6A and 6B respectively secured together by any suitable cabinet construction. Desirably the walls and the panels are of wood and may be of ply wood or other materials. Cross pieces 7 connect the side panels below their upper edges 4A and consti-tute points of connection for legs 8.

Each case supports and partially encloses a string unit and the string units themselves can be varied in detail as is illustrated by the units indicated generally at 9A and 9B. Each string unit includes a base 10 of tubular met-a1, preferably welded steel tubing, of rectangular cross section disposed within an opening in the Patented Dec. 25, 1962 .top panel and supported on the cross pieces 7 with one of its broader sides upward. Mounted on the left end of the base and secured thereto as by the bolts 11 is a peg head generally indicated at 12. A trim and spacing plate 13 may be interposed between the peg head and the base to bring the peg head to the desired level.

The peg head is a generally channel shaped member of sheet metal with upturned side walls 14 on which geared winding pins 15 and thumb screws 16 are mounted in any suitable fashion. The inner end of the peg head has an upturned flange 17 that supports a string bridge 18.

The opposite end or right end of the base as viewed in the drawings carries a string anchor and electrical pickup assembly. The pickup assemblies 19A and 19B of the two units 9A and 9B are basically the same but differ in the amount of switching and tuning equipment which they carry as will be described. Basically the assemblies consist of a steel or other magnetically conductive plate 20 secured to the base 10 by bolts 21. An insultaing and decorative finish plate 22 may be lapped on the metal plate. The bolts 21 also secure a tail piece or anchor 23 to the plate and a cover or hand rest 24 is secured over the anchor. Secured to the plate 20 on the left or inner side of the anchor is an electromagnetic pickup 25. The pickup illustrated has three coils 26A and three sets of string magnets or pole pieces 26 and the coils are selectively and variably connectable with each other and tuning elements, not illustrated, to vary the tone of the instrument. A switch 27 mounted on the outer end of the plate 20 controls the connections between the coils and the tuning elements. The details of the pickup mounting and electrical connections may be the same as those more particularly described and claimed in the patent to McCarty and Lover, Number 2,897,709, dated August 4, 19 59. i i V The pickup assembly l 9A differs from the assembly 19B in that the metal mounting plate and trim plate pro- .ject further to the rear as at 28A and support two control elements 29 such as rheostats and a string unit selector switch 30. The electrical output of the two pickups 25 may be selectively connected by the switch 30 to the tone control elements 29 and the output of the instrument as a whole to combine the two outputs or selectively utilize the output of one or the other pickup. The details of the electrical connections are not illustrated as they will be readily understood by persons skilled in t he art. The case 1A is wider than the case 1B to accommodate the extra equipment on pickup 19A. i

The base element10 of each' string unit 9A and 9B is inserted through a slot 31 provided therefor in the top panel 6 of its case and is drawn down tight on the cross pieces 7 by metal bolts 32. The projecting portions 121 of the magnetic plates 20 on which the pickups are mounted and peg heads 12 rest in overlapping sup ported engagement with the top panels 6. Between the peg heads 12 and the magnetic mounting plates 20 the slots 31 are closed and the bases 10 are partially covered by finger boards 33 that are secured to the bases by wood screws 34. i i i i l FIG. 5 illustrates a modified form of string unit in which the base 10C is tubular as in the other units but has its ends cut away in notclies as at 35 and 135. i The inner end flange 17 on the peg head abuts against the vertical end of one notch and the plate 20C of the pickup assembly has a corresponding upturned flange 36 abutted against the end of the notch at the other end of the base. The flanges 17 and 36 transmit part of the force applied to the peg head and pickup assembly by the tension in the strings directly to the base 10C and compensate for the loss of strength resulting from cutting away the ends of the base 10C. The modified string unit C is thinner than the first string units 9A and 9B as the finger board may be omitted by applying fret marks directly to the top of the base 100.
