UNITED STATE;

LEON C. IBENSUN, OF PHELADELFI-IIA, PENNSYLJANIA.

TRUE BONE ATTAC Application filed May 1,

To all whom it may concern:

Be it known that I, LEON C. BnNsoN, a citizen of the United States residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Trombone Attachments, of which the following is a specification.

This invention relates to trombones and it has more particular references to slide trombones, the primary object being to provide a novel attachment therefor whereby said trombone may be more easily balanced and held by the player.

Another object of this invention is the provision of a novel attachment for slide trombones which is adapted for ready adjustment and positioning on the instrument with a minimum expenditure of time and labor.

A further object of this invention is the provision of a novel attachment for trombones of the type referred to which is simple in construction, cheap to manufacture, and very effective in use for the purpose for which it has been designed. With the foregoing and other objects in view as will be more clearly apparent from the following description my inventon essentially consists of a substantially heavy member having threaded into its longitudinal ends telescopic sections which are adapted for gripping engagement with the tubular body portions of the main wind-pipe or for disposition wherever desired on the instrument so as to efiectivelybalance the same and thereby relieve the player from undue physical strain.

In the further disclosure ofthe invention reference is to be had to the accompanying sheet of drawings constituting a part of this specification and in which like characters of reference designate the same or corresponding parts in all the views.

Figure 1 is a side view of a. slide trombone having my'novel attachment applied thereto.

Figure 2 is a longitudinal section through my novel trombone attachment, the same being drawn to an enlarged scale for the sake of clearness; and,

Figure 3 is an outside view of the same taken at right angles to the preceding figure.

Referring more particularly to the views Figure 1 illustrates an ordinary slide trombone including bell portion 1, wind-pipe 5 and playing slide 6 having a cross-bar T ENT.

Serial No. 557,822.

by means of which the playing of the instrument is effected when said crossbar is clasped in the right hand. Now, it is a well known fact that when an instrument of the kind referred to is being played the bell at and playing slide 6 are much heavier than the end of the instrument having the bend 8 therein and in order to balance the horn the left hand and wrist are placed under considerable strain. In order to overcome the foregoing objection and to balance the trombone so that no undue strain is placed on either hand of the operator I employ a counter-balance member designated generally by the numeral 9.

This counter-balance member 9 comprises a main or body portion 10 substantially solid and cylindrical. longitudinally of the aforesaid body portion 10-and at each end thereof 1 make borings 11, 12, the inner ends whereof are slightly counterbored and screwthreaded at 13 1 1 respectively. Slidably fitting the aforesaid borings 11, 12 are shank members 15, it respectively, the outer ends whereof are made of saddle formation as indicated at 1. and each saddle portion 17 is appropriately protected with a liner 18 of leather or other appropriate material which will prevent damage to the finished surface of the instrument when applied thereto. The inner ends of the aforesaid shank members 15. 16 are respectively screw-threaded at 19. 20 for threaded engagement into the aforesaid counter-borings 13, 141 and it is to be particularly noted at this point that said threaded portions 19, 20 are respectively right and left hand screws.

In applying the attachment to the instrument it will be readily seen that the shank members 15, 16 are secured inwardly relative to the body portion 10 so that the saddle portions 17 can be easily passed between and placed in alignment with opposed tubular portions 21, 21 adjacent the curved end or bend 8 of the instrument, rotation of the body portion 10 of the device 9 extending the saddle portions 17 between said tubular portions 21, 21 until the liners 18 grip or impinge the outer faces thereof. Obviously the on er surface of the body portion may be roughened. serrated or scored so as to provide a suitable hand-hold or grip to manipulate the device.

Now it will be perfectly clear to those acquainted with the art to which this invention appertains that by my invention I have provided a simple and efl'icient counter-balance attachment'ior musical instruments of the nature referred to, its use, advantages and application thereto being perfectly obvious Without further explanation or description. While I have shown and described a preijerred embodiment of any invention I do not desire to be limited to the precise details enumerated as it will be obvious the same are susceptible oi minor changes and variations without departing from the spirit and scope of said invention as more specifically defined by the appended claims.

Having described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A counter-balance attachment for trombones comprising a substantially solid elongated body portion, axial longitudinal borings in the ends oi said body portion, the inner ends whereof are screw-threaded in reverse direction, shank members for fitting in the aforesaid borings and having their inner ends reduced and screw-threaded for engagement in theaforesaid threaded counter-borings, the outer ends of said shank members being adapted for gripping engagementbetween opposed'tubular portions of the trombone.

2. A counter-balance attachment for trombones comprising a substantially solid elongated body portion. axial longitudinal borings in the ends oi said body portion, the inner ends whereof are screw-th1.eaded in reverse direction, shank members for fitting in the aforesaid borings and having their inner ends reduced and screw-threaded for engagenumt in the aforesaid threaded counter-borings, the outer ends of said shank members being of saddle fori'nation and lined with leatncr 'i'or gripping engagement between opposed tubular portions of the trombone adjacent its bend.

Intestimony whereof-l afiix my signature.

LEON C. BlilN-H )N.
