UNITED STATES PATENT OFFICE.

ANTHONY D. SAN UY AND CHARLES ENGELBERT, OF FORT TOTTEN, NEW YORK.

OILING- DEVICE FOR TROMBONE-SLIDES.

Specification of Letters Patent.

Patented June 18, 1918.

Application filed June 1, 1917. Serial No. 172,144.

To all whom it may concern:

Be it known that we, ANTHoNy D. SANUY and CHARLES ENGELBERT, citizens of the United States, residing at Fort Totten, in the county of Queens, State of New York, have invented certain new and useful Improvements in Oiling Devices for Trombone-Slides; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in trombones or like wind instruments which have slides, and particularly to devices for oiling the slides of such instruments.

One object of the present invention is to provide a novel and simple device whereby the slide can be quickly and easily oiled and Without the usual inconvenient practice of carrying a bottle or other receptacle of oil in the pocket.

Another object is to provide an oiling device which forms a part of the trombone and which is within easy reach of the hand which operates the slide, so that oil can be supplied to the slide, even while playing.

Another object is to provide an oiling de vice for a trombone slide which can be quickly and easily taken apart for cleaning and repairs.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of a trombone showing my invention applied thereto.

Fig. 2 is an enlarged sectional view taken on the line 2--2 of Fig. 1.

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1, enlarged.

Fig. 4 is a vertical sectional view taken on the line 44 of Fig. 3.

Referring particularly to the accompanying drawing there is shown a slide trombone which includes the tube 10 and tube 11 connected together by means of the curved section 12. To one end of the tube 10 there is connected the bell 13. Parallel to the tube 10 there is arranged a tube 14 which carries the mouthpiece 15. Engaged on the other ends of the tubes 11 and 14 is the U- shaped slide 16, the inner ends of the arms of which are connected by a transverse bracing tube 17 which forms the hand grip for reclprocating the slide. An arcuate tube extends between and is connected to the tubes 11 and 14, and has its highest point of its arch secured to the intermediate portion of the brace tube 17 Through the points of contact of the tubes 17 and the arcuate tube 18, there is formed an opening 19, the purpose of which will be referred to later. In the opposite side of the tube 17 and directly opposite the opening 19, is a transversely disposed dividing wall 20, the upper edge of which terminates adjacent the opening, but without contact with the tube 17. In the other side of the tube 17 diametrically 0pposite to the opening 19, is formed an internally threaded opening 21, in which is engaged a threaded plug 22. Secured to this plug and extending transversely in the tube 17, is a needle valve stem 23, the point of which is arranged to seat in the opening 19. This plug is provided with a cap 24 in which are formed the pair of openings 25 for the reception of a key to turn the plug for the purpose of seating and unseating the valve. An opening 26 is formed in the tube :17, adjacent the plugs, and through this opening there is disposed a stem 27, the outer end of which is provided with a button 28, while the inner end is screwed into one end of a flexible metal strip 29, the other end of this strip being connected with the needle valve. On one face of the strip is formed a boss 30 which bears against the inner face of the tube 17 and acts as a fulcrum for the strip, whereby when the stem is pushed inwardly the strip will be rocked to cause the unseating of the valve. A coil spring 31 is disposed on the valve stem and bears against the plug and the collar 32 carried by the valve stem.

On the arms of the slide, adjacent the brace tube 18 and the tube 17, there are the collars 33, and disposed within these collars are the washers 34. Through these washers the tubes 18 and 17 slide, as will be readily understood.

The tube 17 is adapted to contain a supply of oil and when the stem 27 is operated the valve will be unseated to permit a small quantity of oil to flow through the opening 19 into the tube 18, from whence it runs to the ends of the tube 18. On the arms of the slide, at the ends of the tube 18 there are formed small oil holes 35, through which the oil from the tube 18 passes to the tubes 11 and 14:. As the slide is reciprocated the oil will be properly distributed along the tubes so that the slide will move freely. The washers prevent the oil from overflowing onto the tubes 11 and 14-, and onto the arms of the slide. I

The oil receptacle being mounted on the slide, and particularly on the hand grip thereof, provides a convenient means of oiling the slide while playing, and obviates the necessity of carrying a bottle of oil in the pocket with the consequent soiling of the clothes of the player.

The opening through which the stem 27 passes is formed with a threaded flange 86, on which is engaged a screw cap 37, and in which is disposed a packing washer.

What is claimed is:

1. The combination with the tubes of a trombone and the slide mounted thereon, of transverse hollow braces connecting the inner ends 01 the arms of the slide, one of said braces being arranged to contain a 4 supply of oil, and the other brace having communication with the interior of the slide, said braces being connected at their intermediate portions and formed with a communicating oil opening, a valve seated in the opening, and means carried by one of the braces for actuating the valve.

2. A trombone slide including a pair of parallel tubes, a straight tube extending between and connected to the said tubes and arranged to contain a supply of oil, an arcuate tube extending between and connected to the slide tubes and communicating therewith by means of openings formed in the tubes, said arcuate tube being connected at its in termediate portion to the intermediate portion of the straight tube and communicating therewith by means of an opening, a spring; pressed valve seated in said opening, means engaging the spring for regulating the tension of the spring and the seatingot' the valve, a rocking strip disposed in the arcuate tube and connected to the valve, and a stem disposed through the straight tube and connected to the other end of the rocking member.

In testimony whereof, we aifix our signatures in the presence of two witnesses.

ANTHONY D. SANUY. CHARLES ENGELBERT.
