DESK FOR PIANOS.

Specification of Letters Patent.

Patented July 1'7, 191?.

Application filed June 10, 1914. Serial No. 844,344.

To all whom it may concern:

Be it known that I, RICHARD W. GERTZ, a citizen of the United States,- residing at Brookline, county of Norfolk,'State of Massachusetts, have invented an Improvement in Desks for Pianos, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to music desks for pianos and particularly to music desks for grand pianos. The invention has for its object to provide a music desk of novel construction in which the brace or support for the desk which holds it in its open or operative position is of novel construction, is permanently secured both to the desk and to the rear rail of the music rack, andrequires no adjustment or manipulation to place it into operative position when the music desk is open. As a result, the opening of the music rack involves merely swinging it up from its folded or horizontalposition into its open position without requiring any manipulation of the brace or support, the latter automatically assuming its operative position when the music desk is swung into its open position.

I have illustrated in the drawings, a.

selected embodiment of my invention which will illustrate the principle thereof, and in the drawings, Figure 1 is a plan view of the music desk embodying my invention showing the desk folded;

Fig. 2 is a section on substantially the line wzc, Fig. 1, showing the desk open and ready for use;

Fig. 8 is a similar sectional view showing the desk folded.

The music desk is shown at 1 and may be of any suitable or usual construction. It is pivotally secured at its lower end to the front rail 2 of the music rack 3 which may be of any suitable or usual construction and is herein shown as comprising the two end pieces 4 that are connected by the front rail 2 and the rear rail 5. The end pieces 4 are herein shown as of suflicient size to constitute lamp supports, this being a common method of making devices of this nature, although it is not essential to the invention. The front rail 2 is of usual constructiomit having the serrated upper surface 6 on which the music rests and the upturned flange 7 at the rear end, to the upper end of which the music desk 1 is hinged by suitable hinges 8. The parts thus far described are or may be of any suitable or usual construction.

My invention relates particularly to the brace, by which the music'desk is sustained in its open or operative position shown in full lmes Fig. 2. Thls brace is permanently secured to both the music desk 1 and gether in some suitable way, as at 11. The

section 10 is pivotally connected to the rear rail 5, as shown at 12, while the upper end of the section 9 is pivotally connected to the music desk 1 by a suitable hinge, as shown at 13. In making my brace construction, I propose to make the two sections 9 and 10 thereof with attaching leaves 14: and 15 which are hinged to said sections 9 and 10 by the hinges 13 and 12. These attaching leaves 1 1 and 15 may be secured to the desk 1 and rear rail 5 in any suitable way. As herein shown, they are provided with aper-- tures similar to the leaves of an ordinary butt hinge to permit them to be screwed to the desk and rail, respectively. The hinge construction 13 is such as to permit the attaching leaf 14 to be folded upagainst the member 9 and similarly the hinge construction 12 is such as to permit the section 10 and the attaching leaf 15 to fold up against each other. The section 9 is longer than the section 10. The relative lengths of these two sections preferably are such that when the music desk is folded, as shown in Fig. 3, the hinge portion 11 will come substantially at the lower edge of the desk and because of the fact that when folded the top face of the desk 1 stands above the top face of the rear rail 5, the two sections 9 and 10 of the brace will have a slight angle to each other, as clearly seen in Fig. 3. When the music desk is opened up the section 10 will fold over against the top of the rear rail 5,

as shown in Fig. 2, and when it assumes this position it forms a rest to hold the lower end of the section 9 which being pivotally connected to the music desk 1 constitutes a rigid brace to hold the desk inits operative position. The desk. can be opened and rear rail 5 and rear of the desk, respectively, against whi'ch the sections and 9 ofthe brace engage as the desk 'is'openedor closed. Itwill be observed that my invention is'eix tremely simplein construction and has the advantage that the brace requiresno han d "manipulation to bring it into operative position'. Further because it is firmly'secured to both [the rail 5 and the music desk 1, it w ll firmly hold'the music desk in its open positionwhile allowing it to be readily folded.

' 'bodiment of my invent on, I do not wish to -=Although'I have described a selected embe "limited to the constructional features 'Oopiesfof this patent maybe obtained for shown. g I r V ,I claim:

' In a music deskjstructurefor pianos, the

"combination With a 'frame'or supporting portion comprising separated front and rear rails, of a music desk hinged to the front rail to fold'forwardly thereof into horizontal position, and a jointed brace member 'comprising a strut section and rest section pivotally connected together, the rest section being shorter than the strut section, said strut section being pivoted to the back of the music desk and the rest section being pivotally connected to the front edge of the rear rail so as to fold over against the top of said rail, the front and rear rails being spaced from each other a distance substantially equal to the length of the rest section whereby when the music desk is folded forwardly into closed position the joint between the 'two sections comes at the lower edgeofthe desk.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
