piano players, and has for one object to pro.

vide a new and improved means for holding the record in proper register with the tracker. range.

It is illustrated diagrammatically in one fcrm in the accompanying drawings, where- 1n Figure 1 is a side elevation in part section; Fig. 2, a section along the line 22 Y of Fig. 1; Fig. 3, a section along the line the panel A 3-3 of Fi 2; Fig. 4, a section along the line4-4 0 Fig. 2; Fig. 5,-a front elevation of the tracker plate; Fig. 6, a front elevation of the tracker range with the tracker plate removed.

Like parts are indicated by like letters throughout the several figures.

The shelf A carries the parallel uprights A which are connected along one side by The shaft B is rotatably mounted in the uprights A and carries the roller B upon which may be wound the record strip B having the playing slots or perforations B therein, andwhich is wound at the other end upon the roller B removably journaled upon the shaftsB, Bfithe shaft B bein "slidably mounted within the sleeve B an held against the end of the roller B by any'suitable spring or other mechanism. The hollow tracker range 0 is located between the rollers B and B and carried upon the casing C which is mounted upon the panel A and is provided with the tracker plate C slidably mountedthereon, upon which the record B rides as-it travels between the rollers. The hollow tracker range G contains the parallel-sided inclined openi'n s or slots-C communicating with the ducts 5 in the casing C which lead to the primary pneumatics not shown. The tracker plate C is provided with the circular perforations C each in register with one of, the slots C. The tracker plate C is guided by the" screws either end and, held against the tracker range'by'means of the springs D The rods or buttons D? which project upwardly in the nclined slots 1) at through the inclined slots D in either-end of the tracker plate, are so located that the distance between their opposed sides is substantially equal to the width of the record B are provided with the curved ends D extending slightly above the surface of the tracker plate and are pivotally mounted at either-end upon the lever D which carries at its other end'the valve D in opposition to the tube D The spring D in opposition to the lever D, is adapted to hold the valve D in the closed' position. The tubes D lead each to one of the primary pneumatics E located within the vacuum chamber E and which carry-the valves E in the passages E in opposition to the ports E", E to control the operation of the motor pneumatics E. The tube E leads from the vacuum chamber E to any suitable vacuum pump not shown. The motor pneumatics E are provided each with the downwardly extending lug F having the perforation F through which passes the rod F 'carrying the adjustable stops F each in opposition to one of the lugs F and the adjustable stops F 5 in opposition to the sp'ringF. The bell crank lever F which is pivotally mounted upon the shelf A, is. in pivotal: connection at one end with the rod F and'at the other end with the rod F carrying the rack F The shaft G which is pivotally mounted at either end in the uprights A carries at one end the pinion G In engagement with the rack "F and thepinions G in engagement with the racks (5: having teeth substantially longer than the width of the teeth of the pinion, and located upon the under side and "-'near either end ofthe tracker plate G I y It will be evidentthat while I have shown in my drawings an operative device still many changes might be made in size, shape and arrangements of the parts without deare as follows :i When the player is operated and the record strip passes across the tracker range, any transverse'motion of the strip will bringit over the buttons or pegs projecting above the surface of the tracker plate and the pressure of the air upon the strlps will cause it to depress these buttons, thus operating through the usual train of primary and motor pneumatics a shaft located within the tracker range. The rotation of this shaft operates by means of pinions engaging racks on the tracker plate to move the tracker plate along the tracker range in a direction parallel with the motion of the strip. The fixed guide screws engaging the inclined slots in the tracker plate, however, compel the plate to move in a direction parallel with the inclined slots, that is, in a direction at an angle to the direction of the record. The result of this is that the tracker plate follows the record so that at all times the holes within the tracker plate are in proper register with the slots or perforations in the record, "but since the slots in the tracker plate are parallel with the inclined slots in the tracker range, the holes in the tracker plate will be at all times in register with the proper slots in the tracker range, and thus the displacement of the tracker plate will not affect in any way the operation of the instrument. The spring in connection with the rod which is operated by the motor pneumatics tends normally to hold them in the central position and thus retains the tracker plate in its central position on the tracker range.
