(Cl. 84-174) The invention relates to pianos and has as a general object to provide a novel and improved construction resulting in a piano requiring only a small amount of floor space yet having an artistic, decorative appearance and a large soundboard area and long strings to assure a fine tonal quality.
More particularly it is an object to perfect a new type of piano having the frontal appearance and the decorative value of a grand piano, coupled with the tonal beauty and sound quality resulting from long strings and a large soundboard area, yet requiring only a small amount of floor space when compared with a grand piano of comparable string length and soundboard area.
Another object is to provide a piano having as its main mass a horizontal section housing the action'and the keyboard, which section is closed at its ends by horizontal structural members disposed at approximately the height and having the vertical dimensions and general appearance of a grand piano rim, and between the rear ends of which there is secured in upright position a backframe, soundboard, string-plate and strings, the backframe extending downwardly from the horizontal members to rest on the floor and extending upwardly a short distance above the members, and being supported in upright position 30 through the horizontal members by legs depending from the forward ends of the members.
Another object is to perfect a piano having wide horizontal side members disposed at approximately the height of the sides of a grand 35 piano and forming the ends of a housing for the piano action as well as the keyboard, and a vertical backframe and harp secured between the rear ends of the members, the backframe and harp extending above the horizontal members a short 40 distance and being enclosed in a narrow housing a portion of which is removable to provide ready access to the tuning pins.
Yet another object is to provide a piano having a. vertical backframe and harp with vertical side panels extending over a portion only of the height and secured to the backframe but performing no supporting or structural functions.
A further object is to provide a piano having an upright backframe unstable in vertical posi- 50 tion, a keybed having portions extending rearwardly and rigidly secured to the backframe, horizontal side members secured at their lower edges to the keybed and also secured at their rear ends to the backframe, and legs supporting 55 the forward ends of the side members and the keybed thereby in turn maintaining the backframe in stable vertical position.

While the invention is susceptible of various modifications and alternative constructions, it is here shown and will be described hereinafter in a preferred embodiment, but it is not intended that the invention is to be limited thereby to the specific embodiment shown, but it is intended to cover all modifications and alternative constructions falling within the spirit and scope of the invention as defined by the appended claims.
Forming the basic part of all pianos is the frame or skeleton upon which are supported the tone producing means, such as the piano harp, generally designated 9, the action, generally desig nated l0, and the keyboard I I, and to which is attached the encasing and concealing structure for the tone producing means. As best seen in Figs.
5 and 6, the frame of the piano disclosed herein is of novel and improved construction creating a new piano form, which in its composite whole has the artistic and decorative appearance of a grand piano as well as the tonal quality obtained only by long strings and a large sound board area without requiring 2 large amount of floor space. In order to obtain these results, particularly the artistic and decorative appearance, the frame or skeleton comprises horizontal structural side arms or members l2 extending the full depth of the piano. These members are of considerable vertical width and preferably are disposed at approximately the heightand have the vertical dimensions of the cheek or rim of a grand piano, and constitute the ends of a horizontal section housing the action l0 and the keyboard. More particularly, as best seen in Figs. 2, 3 and 6, each member I2 is rectangular save for the upper forward corner, here cut away but which may well be retained, and is disposed opposite the action It? with its upper edge lying in a plane just above the action and with its lower edge 1ylng a plane slightly below the keyboard. In length from front to rear each member l2 approximates the distance from the front of a grand piano to the bend in the rim on the treble side.
To obtain long strings and a large soundboard area without requiring a large amount of floor space, means is provided for supporting the piano harp in uprightposition. Accordingly there is disposed between the horizontal members i2 and permanently and rigidly secured directly to the rear ends thereof, by gluing or other well known manner, a vertical backframe generally designated IS. The backframe i3 is composed of a plurality of vertical timbers i l equally spaced horizontally at both the top and the bottom by filler blocks l5 secured therebetween and concealed by dressing boards l5 and ii. Extending horizontally near the top of the backframe and secured thereto to form a part thereof is a pin plank $8. The backframe extends downwardly below the horizontal members i2 so that its weight is supported on the floor, preferably through casters i9, and the backframe also extends a short distance above the horizontal members it to provide additional string length and to facilitate tuning as will become apparent hereafter. A hand grip 2b is secured between each end timber and the adjacent timber to facilitate moving and handling of the piano.
Completing the supporting frame or skeleton of the piano are a keybed generally designated 23 and front legs 26 supporting the forward ends of the horizontal members i2 and through the members maintaining the backframe in upright position. Herein the keybed 23 comprises longitudinal planks 25 and transverse connecting planks 25. At each end of the keybed is a transverse strip 2'i' secured beneath the respective member l2 and having a finger 28 extending rearwardly and secured in any well known man ner to the backframe. The front legs 2 in turn depend from the keybed and are secured thereto by means of a. dowel 2 formed on the upper end of each leg and projecting into an aperture in the keybed. overlying the dowel and the aperture is a plate 29 and projecting through the plate and into the dowel is a wood screw 39. At the lower end each leg is provid d with a caster 3i.
Supported on the backframe H3 in upright position is the piano harp 9 comprising a soundboard 32 secured at its periphery to a liner 33 on the backframe. a metal string-plate 3G and strings 35 secured at their lower ends to the string-plate and at their upper ends on tuning pins 36 mounted in the pin plank 18. The string-plate 34 is very securely fixed to the backframe to be reinforced and held thereby against buckling under the tremendous tension of the strings. In addition, near the center of the string plate in the lower portion thereof is a. reinforcing rib 37, shown in Fig. 4, which projects forwardly a substantial distance. It is believed apparent that as a result of the vertical mounting of the backframe and piano harp, particularly with the projection of the harp above the horizontal members l2, long strings and a large soundboard area are obtained without materially increasing the depth of the piano beyond that required to house the action and keyboard.
In conformity with the employment of an upright harp, though the action ill is housed in a' horizontal section, it is herein disposed in upright or vertical position in front of the strings with the hammers 38 thereof lying just below a plane through the upper edges oi the horizontal memmounted in well known manner on the keybed 23.
Pedals 39 for modifying the tone are supported on a foot 60 depending from the keybed.
Encasing the portion of the backframe and harp extending above the horizontal members 52 are narrow vertical panels 415 and corner mouldings 35 secured on each side of the backframe. These panels and mouldings are just slightly wider than the combined depth of the backframe and harp so as to project forwardly of the tuning pins a slight distance. The top edge of the frame is concealed by a dressing board ll secured to the top edge of the backirame and having its forward edge terminating approximately flush with the ends of the tuning pins. Hinged to the rear edge of the dressing board is a cover 68 which when in closed or horizontal position is flush with the upper edges of the mouldings 66 and its forward edge also is flush with the forward edges of the panels 45.
Covering the tuning plus is a panel 5d disposed just in front of the pins and fitting within the housing formed by the vertical panels G5, the mouldings 4E and the cover d8 (Fig. 2). In the present instance, the panel 50 is mounted on a cover member 5i resting on the upper edges of the members 52 to form a closure for the action housing. The vertical panels d5 are cut away at 52 to receive the rear edge of the cover member 5! in order that the panel 56 may fit within the panels 415. Disposed in front of the action and at its ends extending from the keyboard to the cover member 5! is a front panel 53. The forward edge of the cover member 5i, at the ends of the member, projects beyond the panel 53 to enable a screw 5 to extend through a plate 55, secured to the panel 53, and thread into the under side of the cover 5! where it is easily accessible yet normally concealed. As best seen in Fig. 1, two such securing means for the cover are provided and they are the only means by which the cover and the panel 58 are secured so that both are readily removable as a unit to provide for convenient access to the tuning pins and the action.
In order further to enhance the beauty of the piano and accentuate its predominantly horizontalappearance, a music rack 58 spaced forwardly from the panel 58 and extending above the cover 5! is provided. The rack is mounted on a shelf 57 secured at its forward edge on the upper edge of the panel 53 at a cut-away portion 58 intermediate its ends. To accommodate the music rack 56, the cover member 5i also is cut away at 59 (see Figs. 2 and '7). The cut-away portion may take any artistic shape, but herein is generally rectangular with the inner corners rounded. At the forward edge of the cover member 5!, the cut-away portion coincides with the cutaway portion 58 in the front panel but the shelf 57 projects slightly beyond the cut-away portion the music rack 56 on the shelf serves the twofold purpose of positioning the rack at the proper height for one seated at the piano and providing an opening through which the sound may issue.
The piano is provided with a closure for the keyboard shown in open position in Fig. 1 and which may be swung downwardly into horizontal position to conceal the keyboard.
The portion of the backframe and harp below the horizontal members 12 is encased at each of the side edges by a vertical panel 65 secured to the backframe. This panel preferably is slightly narrower even than the upper panel 45 and is in fact just equal in width to the depth of the backframe, soundboard and string-plate exclusive of the reinforcing rib 31 on the plate. The panel carries a moulding 66 (see Fig. 4) and a leg 61 having a caster 68 at its lower end. The major weight of the piano however is carried by the casters l9 and the leg 61 is primarily for appearance and need not constitute a structural member.
Extending between the mouldings on the lower panel 65 is a bottom board 10 completing the encasing of the lower portion of the harp and soundboard. At its side edges the bottom board is flush with the forward edges of the moulding 66 but near the center extends forwardly to accommodate the reinforcing rib 31 on the string-plate. As here shown the bottom board is bowed but may have any other shape so long as it starts from the forward edges of the side panels and extends forwardly near the center to accommodate the rib 31. The upper edge of the bottom board is spaced downwardly a short distance from the keybed to provide an opening H for the issuance of sound (see Figs. 1 and 2).
In Fig. 8 a simplified construction for the mounting of the music rack is shown. In the simplified construction neither the front panel 53 nor the cover 5| is cut away and the music rack 56 is mounted directly on top of the cover 5|. This facilitates construction and also facilitates tuning of the piano after construction because this rack is now removed as an incident to removal of the cover 5|.
It is believed apparent from the foregoing that I have created a new piano form which in apperance is predominantly horizontal and thus has the artistic and decorative value of a grand piano, but which structurally incorporates a vertical backframe and harp so as to provide the long strings and large soundboard area essential to fine tone without requiring a great amount of space. This results primarily from the use of wide, horizontal side members which are structural members and serve to support the backframe, secured between them, in upright position and to cover the action as well as the keyboard. In addition these advantages are coupled with facility of manufacture and an economy in the amount of material required.
