INVENTOR pensive,

HENRY S. MAYNARD, OF'GLENVIEW, LLINOIS.

MB INATION-BENCH.

To all whom it may concern:

Be it known that l, HENRY S. illAYNAin), a citizen ol the United States, residing at Glenview, in the State o'l' illinois, have invented certain new and useful Improvements in Combination-Benches, o'll which the Yl'ollowing is a specification.

My invention relates to combination seats, and particularly to seats adapted to be used either as piano seats or pianola seats and the invention has 'lor its objects: to provide a seat which may be easily changed l'or use either with a piano or pianola and which ait-er changing may be securely held in adfusted position; to provide a seat which may be moved vertically and tilted by a single operating means; to provide a seat in which thel inclination is automatically i'ixed; and iinally to provide a seat with a simple, inexand reliable operating means. 'lhese obiects and others which will be ap parent to those skilled inthe art are accomplished by my invention, one l'orm ol which is illustrated in the accompanying drawing in which Figure 1 is a partial rear elevation and partial section on the line l-l ci Figure 2,

Figure 2 is a transverse section on the line 2-2 oll Figure 1,

Figure 3 is a partial transverse section taken on the line 3 3 oi Figure 1, the bench being shown Yl'or use with a piano.

Figure 4 is a section similar to that olI Figure 3 but showing the seat ol the bench elevated l`or use in connection with a pianola,

Figure 5 is a detail section showing the ratchet holding means, which section is taken on the line 5-5 o1'I Figure 6,

Figure 6 is a section at right angles to that ol Figure 5 and is taken on tlie line 6-f6 orl Figure 5,

Figure 7 is a section through a modified l'orm oi' seat, and

Figure S is a section through still another modified i'orm o'l'l seat.

Eenches for use with pianos and pianolas are quite similar, but diiier slightly in that the piano bench is level, while the pianola seat is slightly higher and is tilted, which difference is well recognized by those lamiliar with the art. My invention is designed to provide a bench which may be used either with a piano or a pianola, and to this end is provided with a vertically movable seat portion, which is not only capable o1' being elen vated for use with a pianola, but is also ca- Speeication of Letters Patent.

pable o1' being tilted to the proper position, in raising.

Referring to the drawing, 7 is the body portion which may be of any improved ty e, and 8 is the seat which is movable vertica ly with respect to the body portion and is provided with an overhanging portion 9 adapted to conceal the raising mechanism. rl`he raising mechanism consists oi" the rack bar 1() ivoted to the under side oi' the seat at 11, tie link 1.2 provided at one end with the rack 13, and at the other end pivoted at 14 to the downwardly projecting member 15 secured to the under side of the seat, together with the operating means lor the rack bar 1G and the linlr 12, which is the pinion 16 engaging such rack bar on one side and rack 13 on the other side. The link 12 is pivotally supported upon the pivot 17, which pivot 17 engages a slot 18 in the link 1,2 thus providing 'lor a slight motion longitudinally ol' such link, which. longitudinal motion is necessitated by the lact that the lo wer end ol the member 1 5 moves in a right line and not in the arc ol a circle. Fach end o1' the seat is provided with a lifting mechanism similar to that shown in Figures 3 and 4l and the two ends are connected by means oi' the operating rod 19 (sec Fig. 1) upon which the pinions are keyed. The operating rod 19 is adapted to be rotated and held in position by means ci" the ratchet mechanism shown in Figures 5 and 6. As here shown the operating handle 26 is secured rigidly to the rod 19 and carries the pawl 21 adapted to engage the teeth 22 on the bracket 23, which braclet is rigidly secured to 'the body portion o1' the seat. The handle 2O is preferably located opposite the bacli ol the seat as indicated in Figure 1., and by it the two pinions 16 may be turned to any desired position and held securely in such. position. ln order that the rear side el' the seat be elevated more rapidly than the l'rontside when it is desired to use the seat with a pianola, the pivot 17 lor the link 12 is placed nearer to the pivot 1e than to the rack 1.3 so that on the revolution oi' the operating pinions 16 the rack bars 10 will be raised a greater' distance than the members which. are operated by the short end of the link 1.2. The placing of the lever 12 and its gear 13 at the angle indicated in Figure 4 also increases the tilting, as a part o1l the movement of the gear 13 and the opposite end oi' the lever is lateral, thus reducing the vertical movement. The length of the tvvo lever arms on the link 12 are so proportioned that exactly the right tilt is secured When the seat is raised to the position ol Figure 4. The seat is lowered by simply pressing in the pavvl 21 and allowing the parts to move down by gravity, and in raising the seat it Will be seen that it is not necessary to use the handle 20, as the top oi the seat may bejgrasped and lifted to its desired position, the end ol the paw] sliding over the teeth 22 until the seat reaches its proper height.

It will be seen 'from the Vforegoing that the tilt of t-he seat is automatically provided tor, and that one adjusting means accomplishes the double function oi' elevating the seat and tilting it to the desired angle. lt will also be apparent that this operating` means is oi' a very simple and inexpensive kind and one which Will be very eiiiective for the purpose intended. V ari ons modifications, which will be apparent to those skilled in the art, might be made Without departing 'from the spirit oi' the invention as deiined in the appended claims, Which invention requires only that a single operating means be employed l'or raising and tilting the seat simultaneously. lt will also be apparent that the extent ol' tilting oi the seat is dependent upon the relative distances between the pivot 17 and the pivot 14 and rack 13, and that these distances may be varied as desired, to niodil'y the amount oi' tilting.

In Figurif-i 7 a modified lorm ol'l seat elevating mechanism is shown. ln this device a second spur gear and rack are substituted for the links i2 and 15 oi' the device shovvn in Figures 3 and li. Referring to the drawing, 24, 2li are rack bars which are secured to the bottom of the seat 25, 26 and 27 are spur gears, which gears mesh with each other and the rack 24 as shown, the operating?,` mechanism for turning the gear 26 and holding the seat in adjusted position being the same as in the first form ol' device shown.

In Figure 8 is shown still another l'orm oi' seat elevating mechanism. rThe seat is provided with two racks 28, 28 with which the gears 29 and 80 mesh, the gear 30 being mounted on a transverse operating shalt 31 Whose turning and holding means are the same as that for the operating shaft 19 in the irst form oi device shown. The gear 30 is provided With tivo sets olf 0'ear teeth 3.2 and 33 respectively, the first set engaging the rack 28, and the second set 33 engaging the gear 29. As the radius oi'I the gear 33 is less than that of the gear 82, it Will be seen that means lor locking the seat in raised position.

2. A combination bench, comprising a body portion, a relatively movable seat, an operating Igear mounted on the body portion, a raci secured to one side oiA the seat and engaging the gear, a link Vpivotall;T connected to the other side oi' the seat at one end and provided with a rack at the other end engaging the gear, a pivotal support ior the link located 'nearer one end thereof than the other, and means 'for holding the seat in ad.- justed position.

body portion, a relatively movable seat, an

operating pinion mounted on the body portion, means l'or rotating the pinion and holding it in adjusted position, a rack secured at its upper end to one side oil the seat and enthe pinion, a link connected pivotally at one end to the other .side of the seat 'and provided at the end with a rack engaging the pinion, a pivotal support tor the link located intermediate the ends thereof andmeans ior rotating the pinion and holding it in adjusted position. Y

4. A combination bench, comprising` a body portion, a relatively movable seat., an operating gear mounted on the body portion, a rack securedto one side oi the seat and engaging the gear, a link pivotally connected to the other side ol the seat at one end and provided with a rack at the other end engaging the gear, a pivotal support Jfor the link intermediate the ends thereof', and means i'or holding the seat in adjusted position.
