CHRISTIAN H. MARTIN, OF AKRON, OHIO.

ADJUSTABLE BENCH.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed September so, 1912. Serial No. 723,093.

To all whom it may concern:

Be it known that I, CHRISTIAN H. MAR- TIN, a citizen of the United States, residing in the city of Akron, county of Summit,

and State of Ohio, have invented certain new and useful Improvements in Adjustable Benches, of which the following is a specification.

My invention relates to benches which are peculiarly adapted to be used in connection with player pianos, as the seat may be raised from a lower horizontal position to an inclined position at greater height from the floor. The lower level is employed when the pianist is playing upon the keys of the piano in the usual way, while the upper inclined position is particularly adapted for use when the bench is occupied by a person. who is operating the piano by mechanical.

playing means. At such times the greater height from the floor and inclined position are useful in aiding the person playing the piano to operate the pedals with the greatest facility and minimum fatigue. I have shown crossed-lever means for accomplishing this result in my application for United States Letters Patent Serial Number 648,237, patented Dec.24, 1912, Serial Number 1,048,190.

The present application also provides one or more compartments or deep drawers for containing music rolls used in connection with the mechanical device for playing, the piano, which are normally concealed within the body of the bench and which are automatically ejected from the interior of the bench when the adjustable seat is raised to the upper inclined position. 1

In the accompanying drawings which form a part of this specification, Figure 1 is a longitudinal sectional view of my im proved bench with the seat in theupper inclined position and the music roll compartments ejected from the sides of the bench; Fig. 2 is a similar view showing the seat in the lower horizontal position and the music roll compartments retracted within the bench; Fig. 3 is a transverse sectional view on line III-III of Fig. 1; Fig. 4 is a perspective view of the levers used for operating the musicroll compartments, and Fig. 5 is a perspective view of the lever mechanism for accomplishing the raising and lowering of the seat.

Referring to the drawings in detail, the numeral 1 designates a bench having the vertical posts 2, mounted between the upper ends of which is a movable seat 3. The

seat ismounted at each of its shorter sides upon identically similar lever mechanism, each comprising the crossed-levers 4, 5. The upper end of the double lever 4 is pivoted at 6 to a bracket 7 afiixed to the seat, while the upper end of the lever 5 carries a pin 8 received in a horizontal slot 9 in a bracket 10, also secured to the seat. The lower end of'the double lever 4 carries a pin 7 11 which is received in a slot 12 in a bar 13' permanently secured in any suitable manner to a fixed portion of the bench. The double lever 4 and the lever 5 are pivotally connected at 14, and the slot 12 is provided with one or more rests 15, 16 for the reception of the pin 11. The lever 5 is notched at 17 and the bar 13 is notched at 18 to receive the pivot pin 6, when the levers are collapsed, and the bar 13 is further provided with the notch 19 for the reception of the pivot pin 14, when the levers are in collapsed position. The lever 5 is pivoted to the bar 13 at 19 The proportions and operation of the device to accomplish the tilting of the seat when it is raised, without causing its lateral displacement, are fully set forth in my application above referred to and their description need not be repeated here. In addition to these two sets of levers I have shown my device provided with a third set of evening levers 20 and 21 extending along one of the long edges of the seat. These levers are pivotally connected at 22. The lever 21 is pivotally secured at 23 to the bottom of the seat and at its other extremity carries a pin 24 entering a slot 25 in a bracket aflixed to a stationary part of the bench. The lever 20 is pivoted at 26 to a fixed part of the bench and carries at its other extremity a pin 27 entering a slot 28 in a bracket 29 secured to the under-side of the bench. The function of this set of levers is to cause the seat to rise evenly; that is, without tilting from side to side when it is raised. Without these 1evers, unless upward force is applied at the center of one of the long edges of the seat, one of the short edges will be forced higher than the opposite edge, causinga tendency for the seat to jam between the opposite away with this difiiculty.

In connectionwith the seat-raising and The use of the evening levers with 40f sight into the bench.

lowering'devices, I have provided compartments normally received within the body of the bench that do not become evident un-' til the seat is raised to the position for use with mechanically operated pianos. In my improved device the operation of raising the seat causes the compartments to be ejected from the sides of the bench automatically, so that the operator of the piano may readily select the roll which he desires to attach to the piano. When he is through playing, the'mere lowering of the seat will cause the compartments to glide back out These rolls are usually sold in long rectangular boxes labeledupon one end, and I have so proportioned the compartments that the boxes may normally stand upon end therein, with the result that thelabels will be visibleto the operator Whenever the seat is in its ele- I vated position.

In the drawings the numerals 30 and 31 designate the two compartments adapted to reciprocate upon the rollers 32. Each of the compartments has secured to it an angle bar 33 sliding under a roller 34 pivotally secured'to a yoke 35 which is attachedto any suitable fixed part of the bench. The bar 33 and its roller 34 cooperate with the rollers 32to produce an easy sliding action of.

each compartmentinto and from the cavity in the side of the bench provided for it. Means for automatically controlling the 'movement of the compartments include a bent lever 36 pivotally attached at 37 to angle irons 38 and 39 secured to some suitable fixed part of the bench. The curved extremity of each lever 36 is pivoted at 40 to a twisted link 41 which has its other ex- 40 i at right angles to that of the pivot 40, to

"an angle iron 43 adapted to be secured at 44' tremity pivoted at '42, in a plane disposed tothe under-side of the seat. The extremity of the longer arm of the bent lever 36 carries a spool roller 45, the flanges of which embrace a rod 46 secured to brackets 47 and 48, which are. in turn fastened to the inner end of a music roll compartment. The

flanges of the roller 45 are also adapted to press against the inner end of the music roll compartment when the seat is raised.

It will be seen that when the person desiring to use the bench in the elevated posi- I tion raises the seat, the twisted rods 41 will 'be lifted, causingthe'lever 36 to fulcrum about its pivot 37 and draw the longer arm of this lever from the position shown in Fig. 2 into the position shown in Figs. 1 and 4. The flanges of the rollers 45 will bear against their'respective compartments,

forcing them outward from the bench into jthe position shown. in thejtwolast named lfigures. WVhen the seat is lowered into the .position used for playing upon the piano manually, this operation will be reversed.

The levers 41 will then be forced vertically downward, causing the barrel of the spool rollers 45 to engage with their respective bars 46 and retract the two compartments into the interior of the bench. It will thus be seen that the mere raising or lowering of the seat without an undue expenditure of force will cause the music roll compartments to be brought into the position which is desired with the corresponding position of the seat. It will further be obvious that a single compartment maybe used if desired, and that this compartment maybe caused to be ejected from the rear of the bench, instead of from the side.

While I have illustrated and described only one specific modification of my invention, I realize that it is susceptible of wide variation without departing from'the scope thereof and I do not wish to be limited to movable compartment adapted to be received 1 within said bench, a lever pivoted to a fixed part of the bench, a link connecting the lever with the seat, and means for communicating motion from the lever to the compartment. r
