To all whom it may concern:
Be it known that we, WOLF I-IEILBRUNN, SIMON BLtrrn, and WILHELM PAPE, citizens of Germany, residing at 39 Keibelstrasse, Berlin, Germany, have invented new and usei ful Improvements in Musicl?tecorders, of which the following is a specification.
Our invention relates to apparatus for pneumatically marking note or record sheets for automatic musical instruments while the sheet will enable exact reproduction of the piece of music.
The essential feature of the invention is that the recording point for each note is actuated directly by a bellows, the interior of which, on depression of the corresponding key of the instrument, is brought into connection with a low pressure chamber, owing to the opening of an air passage and actuation of a change valve. In this manner extremely accurate and simple transmission is attained. A still more rapid succession of operations for trilling or shaking or the like can be insured by the provision of an extra low pressure chamber'communicating with the said passages between the key-actuated valve and the change valve.
Our invention is illustrated in the accompanying drawing, in which Figure 1 is a front elevation of a portion of a piano to which the new recorder is attached. Fig. 2 is a section on the line AB of Fig. 1.
a is a portion of a piano on which is mounted an attachment of well-known description for winding up and oil the record sheet (1, consisting of the rollers 12 and c, on which the record sheet is wound. This sheet is wholly blank, being provided neither with graphic marks nor perforations. The rollers b 0 may be driven in any suitable manner (preferably electrically) the driving mechanism being ad justed corresponding to the time of the piece of music to be recorded.
On the sheet d the notes are mechanically recorded in the following manner. On the keys 6 being struck, the rear lever-arm f actuates valves g, whereby the mouth of a I passage h is opened. By the entrance of air into this passage a diaphragm i will be moved, whereby in Well-known manner a change-valve lc is operated. On this valve 76 moving to the left, it closes the aperture 1 which conducts to the outside, and the in terior of the bellowsm is connected with the low pressure chamber a. The bellows m immediately collapses and the rod q and bell lever 0 press the pencil or other marking point p against the surface of the unwinding sheet (1. As long as the key 6 is depressed. and air has access to the passage h, the point 29 remains pressed against the unwinding sheet cl and thus makes a mark in order that the part can subsequently cut out of the sheet. For each key the arrangement is naturally exactly the same and likewise for the pedals. When the sheet has thus been fully marked, it can be stamped out inwell-known manner, the perforations made being of exactly the length of the marks made by the point p.
The low pressure in the chambers n is produced by a bellows or the like, from which a flexible pipe 7" conducts to the said chambers.
In order to again suck the atmospheric air out of the various passages h again, another chamber 8 is provided, connected with the suction bellows by a flexible pipe t.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent of the United States is A music recorder comprising in combination for each key, a low pressure chamber having an atmospheric air inlet at one side, a valve for closing said inlet, a diaphragm in the said chamber, a bellows communicating with the chamber at the other side of the diaphragm, a valve controlling the communication of the chamber with the bellows and actuated by the diaphragm, a point adapted to mark the traveling record sheet, a bell crank lever connectedv to said oint and a Witnesses:
