AUTOMATIC CUT-OFF FOR MUSICAL INSTRUMENTS.

To all whom it may concern.-

Be it known that I, CONSTANTIN RIEGGER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a certain new, useful, and valuable Improvement in Automatic Out-Offs for Musical Instruments Operated by Electricity, of which the following is a full, clear, and exact description.

My invention has relation to automatic cut offs adapted to be used on musical instruments which are run by electricity.

The device consists principally of a suitably fulcrumed lever which is so arranged as to be engaged at one end by a lug or other obstruction in oron a traveling sheet of music, whereby the said lever is pushed aside and thereby breaks the current of electricity. This will stop the instrument.

The invention consists of the novel construction and arrangement of its parts as is hereinafter set forth and described.

In the accompanying drawings:-Figure 1, is a side plan view partly in section, of one modification of my invention. Fig. 2, isatop plan view of Fig. 1. Figs. 3,4, 5, 6, 7, 8, 0,10, and 11, are views of different modifications and details of the same which will be explained hereinafter.

My invention as shown in Figs. 1, and 2, consists of the lever 1, fulcrumed at point 2; the upper end of said lever is adapted to engage the metallic rest 3, and the lower adapted to press against the side of the traveling perforated sheet of music 4, said traveling sheet being provided with an incision 5, out in its edge. The said lever is made of spring metal and as the sheetunrolls said lever bears against its edge, butwhen the incision comes to the lever, it is entered by the lever, and as the sheet passes on, the rear edge of the incision will engage the lever and push the upper end thereof away from the rest 3; and thus the current is broken and the instrument stops. The rear edge of the incision 5, is provided with the metallic strips or plates 6, which prevent the lever from cutting through the paper. One of the wires '7, is connected with the rest 3, and the other wire is connected with the lever at point 8. These wires also connect with the motor and battery, which are located at any convenient part of the instrument.

In Fig. 3, the construction of the lever is changed in one respect only from that shown in Fig. 1. The lower end of the lever in Fig. 1, is bent out to press against the edge of the traveling sheet, but in Fig. 3, the lever is straight however the remaining features are identical with those shown in Fig. 1.

The traveling sheet in Fig. 3, instead of having the incision in its edge, is provided with the metallic bar 9, running all the way across the sheet and having one end projecting beyond the edge of the sheet. This projecting end is adapted to engage the lower end of the lever, and thereby break the current.

Figs. 4 and 5, show the traveling sheet with the slot 10, cut in it. The lower end of the lever is provided with the roller-l1. This roller runs along on the sheet and when it comes to the slot the lever falls through and the upper end of the lever disengages the rest 3. (See dotted lines Fig. at.) Thus the current is broken.

Figs. 6, and 7, are plan views of levers having a hinged section with a roller journaled to the lower end thereof. Said roller is adapted to run along on the sheet and enter the slot, and thereby throw the upper end of the lever away from the rest This lever is provided with the spring 12, which keeps the lever steady against the rest and also pushes the lever back in place when the lower end of the lever is disengaged from the slot.

Figs. 8 and 9, show the lever and its attachments underneath the sheet. The lever as shown in these figures is provided on one end with the attachment 13. This attachment is pivoted to the end of the lever at right angles and one end of the attachment is heavier than the other, thereby causing the lighter end to press up against the under sheet of the paper. The paper is provided with a slot and the upper end of the attachment will enter this slot and thereby cause the lever to be pushed around, as indicated by the dotted lines in Fig. 8, this will break the current.

Fig. 10, shows a modification in which the lever operates from the lowerside of the sheet. The sheet is adapted to run along on the upper end of the lever and the sheet is thus bent at an angle. The upper end of the lever will enter the slot and the lever is turned and the connection thereby broken. One wire in the construction connects with the lever and the other wire connects with the spring connection 14.

Fig. 11, shows a modification in which the lever operates under the sheet. The end of the lever bears againts the under side of the sheet, and is held up by the spring 15. The

upper end of the lever will enter the slot and the end of the lever is thereby pulled away from the rest 3, and thus the current is broken.

Having thus described my invention, what seams
