Stop Arms Used on Schmid Horns

Engelbert Schmid horns use seven different stop arm designs. The difference lies in the position of the indexing pin, and in the case of triple horns, in the use of a stop arm with two screw positions. Use this guide when ordering replacement stop arms to ensure getting the correct part. All Schmid stop arms (except PTESS6) are also available set up for ball-and-socket action.

 

   

PTESS1

Indexing pin at 1:30 o'clock. Used on 1,2,3 valves on all models, 4th valve on double horns. This is the standard stop arm and has no stamped number. (Use PTESS+ on number 4 valve to make horn stand in Bb.)

   

PTESS4

Indexing pin at 12 o'clock. Used on number 4 (high eb or f change valve) valve on descant and triple horns. It is stamped "4".

   

PTESS5

Indexing pin at 3 o'clock. Used on number 5 (high eb or f change valve) valve on descant and triple horns. It is stamped "5".

   
PTESS+

Indexing pin at 4:30 o'clock. Used on A/stop (+) valve on ES2 double horns. Also used on the number 4 valve on double horns to make the horn stand in Bb. It is stamped "+".

   
PTESS67

Indexing pin at 6 o'clock. Bb/F change valves on triple horns (valves nos. 6 and 7) when the horn is to be used primarily standing in Bb.

   
PTESS8+

Indexing pin at 7:30 o'clock. Used on A/stop (+) valve on descant horns. It is stamped "8+".

    PTESS6

Two stop arm mounting holes. Indexing pin at 7:30 o'clock. The string screw also serves as the stop arm. Used on valves number 6 and 7 on triple horns when the ability to change base keys is required. If the screw is in the left-hand hole, the horn will stand in Bb. If it's in the right-hand hole the horn will stand in F. Both valves need to be in the same orientation.
