HUGO AHLSTRAND, OF EVERETT, MASSACHUSETTS.
BRIDGE FOR STRINGED INSTRUMENTS.
SPECIFICATION forming part of Letters IPatent No. 566,835, dated September 1, 1896.
Application filed November 8,1895. Serial No. 568,265. (No model.)
To all whom it may concern:
Be it known that I, Huco AHLSTRAND, a citizen of the United States, and a resident of Everett, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Bridges for String Instruments, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to improvements in bridges for string instruments, particularly well adapted for guitars and mandolins, and it is carried out as follows, reference being had to the accompanying drawings, Wherein Figure 1 represents a top plan view of the invention. Fig. 2 represents a cross-section on the line 2 2, shown in Fig. 1. Fig. 3 represents a cross-section on the line 3 3, also shown in Fig. 1. Fig. 4 represents an end view seen from X in Fig. 1. Fig. 5 represents an end View seen from Y in Fig. 1, and Fig. 6 represents a sheet-metal blank from which the improved bridge is made.
Similar letters refer to similar parts wherever they occur on the different parts of the drawings.
In the drawings, Figs. 1, 2, and 3, A represents the top sounding-board of a guitar, mandolin, or similar string instrument for which my improved bridge is used.
The bridge consists of a sheet-metal baseplate B, adapted to be secured, preferably by means of screws, to the top board A, as shown in the drawings.
Integral with the plate B is made a curved longitudinal string-holder 0, having a series of circular perforations D, each about large enough to receive one of the strings E, which is held in place by making a knot e thereon, as shown in Fig. 2.
Below each perforation D is made a somewhat larger perforation F, at the upper end of which is a rearwardly-projecting lip f, which latter serves as a smooth support for the string, which is passed through said perforation F after going over and back of the string-holder O, as shown in Fig. 2.
G is the vertically-adjustable bridge-bar, which is guided between projections H H, formed integral with the plate B, as shown.
I I are adjustingscrews screwed through the bar G and having their lower ends resting on the plate B, as shown in Fig. 8.
By adjusting the position of the screws I I the bar G may be raised or lowered, as may be desired, for the purpose of regulating the distance of the strings from the finger or top board.
What I wish to secure by Letters Patent and claim is The herein-described improved bridge for string instruments consisting of a sheet-metal base-plate B having at its lower portion a curved string-holder 0 provided with perforations D, F and supporting-lips f and an adjustable bridge G guided on the base-plate and having adj Listing-screws I for regulating the position of the strings relative to the sounding-board substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 30th day of October, A. D. 1895.
HUGO AHLSTBAND.
