MUSIC-DESK FOB PIANOS.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed. October 3, 1913. Serial No. 793,219.

To all whom it may concern Be it known that I, ALB1N WILBERG, a citizen of the United States, residing at De Kalb, in the county of Dekalb and State of Illinois, have invented new and useful Improvements in Music-Desks for Pianos, of which the following is a specification.

The invention relates to pianos, and more particularly to casings therefor, and has for an object to provide a music supporting desk or member for the casing.

The invention embodies, among other features, the provision of a swinging front section arranged and constructed so as not to rattle, and which can be readily swung into open or closed position relatively to the casing, the said swinging front section being furthermore adapted to constitute a supporting rack for music and the like.

The invention further embodies the provision of a swinging front section more particularly known as a music desk for use on upright pianos and which can be readily swung into an open position relatively to the casing and held in this position or as easily swung into closed position on the casing, with means for accomplishing this result.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a vertical sectional view taken through the piano casing, showing the swinging section in closed position; Fig. 2 is a similar view showing the swinging section in open position; Fig. 3 is a fragmentary vertical sectional view showing the manner of swingingly supporting the section on the casing; Fig. 4 is a vertical sectional view taken on the line 44 in Fig. 1; and Fig. 5 is a horizontal sectional view taken on the line 55 in Fig. 3.

Referring more particularly to the views, I provide a piano casing 10 having an opening 11 in the front 12 thereof and adapted to be closed by a front section 13 having swinging engagement with the casing 10, this being accomplished through the medium of a plurality of hangers 14 secured to the front section 13 and preferably of a hook-like nature, with the hook portions of the hangers journaled on headed screw bolts 15 carried on the piano casing 10. In order to prevent any rattling of the front section relatively to the piano casing and particularly at the point of pivotal connection of the front section with the casing, a flat leaf spring 16 is interposed between the hangers and the screw bolts as shown.

The lower end of the front section 13 carries a shelf 17 adapted to support music, lying against the front section and secured to the rear face of the front section 13 is a U-shaped supporting member 18 having eccentrically mounted to swing thereon a bar 19 provided with a longitudinal slot 20 terminating at an opening 21 and also including a recess 22. Screws 23 are provided to secure the bearing member 18 to the back of the front section 13 and the said screws also carry and support a spring-like locking member 24 between the supporting member 18 and the front section 13. The bar 19 carries a lateral pin 25 adapted to engage the locking member 24 and operate over the same, the said locking member being provided with an upper recess 26 and a lower recess 27, into which the pin 25 is adapted to be received when the front section is in closed and open positions respectively. A transverse pin 28 is carried by the casing 10 and passes through the slot 20 of the bar 19, as shown.

In order to cushion the front section 13 when it is swung from open into closed position a stop member 29 including a felt cushion 30 is preferably secured to the casing 10 and the cushion thereof adapted to be engaged by the section when the same is moved into closed position relatively to the casing.

When the front section 13 is in closed positiointhe bar 19 will lie in substantially a vertical position, with the pin 25 of the plate rep osing in the upper recess 26. When an upward pull is exerted on the front section the bar 19 will swing on its point of pivotal connection with the supporting member 18, thus causing the pin 25 to be removed from the upper recess 26 and, as the front section is swung outwardly, the bar swinging upwardly and forwardly, will cause the pin 28 to lie in the recess 22, the pin 25 of the bar when the front section has been swung into its outermost position, being adapted to spring into the recess 27, thus with the cooperation of the spring-like locking member holding the front section in open position relatively to the front of the piano casing. hen it is desired to return the front section to closed position it is only necessary to exert a backward pressure upon the face of the front section, thus causing the pin 25 to spring out of the recess 27 and causing the rear end of the plate 19 to gravitate into the position shown in Fig: 1 so that the pin 25 will be again received in the upper recess 26 as is also shown in Fig. 1.

From the foregoing description it will be apparent that my device is of a simple construction, can be readily used in connection with pianos and other similar musical instruments and will efi'ectively perform the work for which it is intended.

Having thus described my invention, I claim:

1. A music desk for pianos, comprising a front section having swinging connection with the front of the piano casing, a bar having pivotal connection with the front section and a sliding connection with the casing, a locking member on the front section, and means carried with the bar and movable over the locking member for holdingthe front section relatively to the said casing.

2. A music desk for pianos, comprising a front section having swinging connection with the front of the piano casing, a bar having pivotal connection with the front section and a sliding connection with the casing, a locking member on the front section, and a pin carried with the bar and movable over the locking member for holding the front section relatively to the said casing.

3. A music desk for pianos, comprising a front section having swinging connection with the piano casing at its upper end, a supporting member carried by the front section, a bar mounted to swing on the supporting member and having sliding connection with the casing, a locking member carried by the front section adjacent the supporting member, and a pin extending laterally from the bar to operate over the locking member and lie in a recess therein to lock the front section relatively to the casing.

l. A music desk for pianos, comprising a front section having swinging connection with the piano casing, a longitudinally slot ted bar, a bearing member carried by the front section and having the longitudinally slotted bar mounted to swing thereon, a pin carried by the casing and operable in the slot of the said bar, a locking member on the front section, and means carried by the bar and adapted to engage the locking member for holding the front section relatively to the casing.

5. A music desk for pianos, comprising a front section having swinging connection with the piano casing, a longitudinally slotted bar, a supporting member carried by the front section and having the longitudinally slotted bar mounted to swing thereon, a pin carried by the casing and operable in the slot of the said bar, a spring-like locking member on the front section, and a pin carried by the bar and adapted to engage the locking member for holding the front section relatively to the casing.

In testimony whereof I afIiX my signature in presence of two witnesses.
