Application August 14, 1940, Serial No. 352,480
7 Claims.
This invention relates to improvements in electrical pickups for stringed musical instruments.
The main objects of my invention are:
First, to provide an improved electrical pickup for stringed instruments having provision for readily and quickly mounting the same on and removing the same from the instrument for selective adaptation of the same for electrical reproduction.
Second, to provide a pickup device of the type described, which is characterized by the simplicity and compactness of its parts.
Third, to provide a pickup which is selectively adjustable to various positions relative to the strings or bridge of the instrument to enable the tones reproduced to be varied as desired.
Further objects relating to details and economies of my invention will appear from the description to follow. The invention is defined in the claims.
A structure which embodies the invention is illustrated in the accompanying drawing, wherein:
Fig. 1 is a fragmentary view illustrating a stringed guitar type instrument with the pickup of my invention operatively associated therewith.
Fig. 2 is a fragmentary enlarged view partially in vertical section illustrating the pickup of my invention in operative relation to the strings of th instrument and novel means whereby the pickup is removably mounted on the same.
Fig. 3 is a fragmentary view partially broken away and in section on line 3-3 of Fig. 4, further illustrating details of the pickup construction.
Fig. 4 is a fragmentary view in section on line 44 of Fig. 3.
Fig. 5 is a fragmentary side elevational view illustrating in further detail the construction of the pickup mounting.
Referring to the drawing, the reference numeral I indicates a guitar type stringed musical instrument well adapted to have associated therewith the improved pickup in accordance with this invention. although it will be apparent from the description to follow that the device is not limited in its application and may be used with any suitable stringed or other instrument having a plurality of vibrators. The instrument described herein includes a tailpiece 2, a bridge 3, and a fret bar 4 with which are associated a plurality of strings 5 in entirely conventional manner. The reference numeral 6 indicates a shield such as is ordinarily associated with instruments of this type.
The reference numeral 1 in general indicates the pickup of my invention which, as illustrated in Figs. 2, 3, and 4, comprise a coil 8 fixedly associated with a permanent magnet 9 and surrounding a vertically extending pole or plurality of pole pieces l0, see Fig. 4. There may be one pole extending across all of the strings 5 or a pole provided with individual pole pieces one for each string, the present invention not being particularly concerned with details of the pickup construction in this respect.
A two-part casing II houses the electromagnetic structure of the pickup, this casing comprising a bottom half l2 having pads l2! associated therewith whereby the casing may be removably mounted on the instrument Without marring the finish thereof. An upper casing half I3 telescopingly engages the lower half and is provided with an upwardly offset portion l4 providing an internal recess accommodating the vertically extending pole or pole pieces Hi. This enables the pole piece to be brought closer to the strings 5, while at the same tim providing ample clearance, for example, at l5, to enable the strings to be vibrated without striking or interfering with the casing l l. I
The electromagnet casing is mounted on the instrument in a novel manner to enable the same to be readily removed therefrom when desired or adjusted with relation to the strings and bridge to control the playing characteristics. This mounting means is illustrated in Figs. 1 and 2 and comprises a clamp l6 made up of a pair of upper and lower sheetmetal string engaging elements ll, 3 respectively, disposed on opposite sides of the strings 5 in the space between the bridge 3 and tailpiece 2 and clampingly engaging the opposite sides thereof. The knurled clamp screws l9 .threadedly engage these clamping memhers to bring the same together and fixedly se cure the same relative to the strings and to the instrument body.
Casing H has secured thereto, as by integral connection to the lowermost casing half l2, a laterally extending wing 20 terminating in a rounded portion or eye 2| to which is rigidly connected the rearW-ardly extending adjusting and mounting rod 22 for the pickup. This connec tion may be effected by Welding, offsetting or other process. The string engaging clamp I6 is provided at one side thereof with an adjustable bight 23 slidably receiving the free end of rod 22 (see Fig. 5) and a thumb screw 24 coacts with this bight to enable the clamp rod 22 to be clamped in any desired adjustment of the rod and pickup casing relative to the strings. Thus, by loosening screw 24, the pickup may be adjusted from the solid line position of Fig. 1 to the dotted line position and vice versa, thereby governing to a considerable extent the tonal qualities of the notes electrically reproduced. If
it is desired to dispense with electrical reproduction, the pickup is quickly and easily removed in its entirety by merely releasing screws l9 and removing the clamp from the strings.
In line with the foregoing purposes, I provide one of the clamping members l1, l8, and preferably the latter, as illustrated in Fig. 2, with an integral projecting arm 25 upon which the volume or tone control 25 is mounted, the same having a knob 21 for manual actuation. This control is connected to the pickup coil by a connector 23.
In order to enable the pickup to be firmly mounted without vibration on the instrument body panel, the casing l l is provided. with a lateral spring finger 29 on the opposite side thereof from the rod supporting wing 20, as illustrated in Fig. 3, which finger resiliently engages beneath the shield B in the manner illustrated in Fig. 1 to prevent any tendency of the structure to vibrate.
By the foregoing, an instrument is provided which is quickly and easily set up for electrical reproduction or not, as desired. The structure is entirely unitary and is compact and simple in its parts. A simple manipulation of the rod clamp screw 24 enables the position of the pickup longitudinally of the strings to be adjusted at will. Of course, the extent to which this adjustment is possible Will be limited to the point at which the pickup casing engages strings however, as clearly illustrated in Fig. 4, the forming of the casing with the upward offset l4 providing the clearance space l5 adds substantially to the space through which the same may be adjusted.
I have illustrated and described my improvements in an embodiment which is very practical. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A pickup construction for a stringed musical instrument which is adjustable on and removable from the instrument, comprising a pickup having a vertically extending pole piece adapted to be disposed adjacent and beneath the strings, a casing including a top casing member housing the pickup and having an offset portion extending above the remainder of the casing member and accommodating the pole piece whereby to provide clearance between the strings and said remaining portion, a guide rod secured to one side of the casing and extending rearwardly toward the tailpiece of the instrument, and a clamp slidably receiving and adjustably clamping said guide rod, said clamp having means for fixedly securing the same to the strings between the bridge and tailpiece of the instrument, said clamp having control means for the pickup mounted thereon and being removable from the strings whereby the pickup construction may be removed in its entirety from the instrument.
