PEDAL MECHANISM.

Specification-of Letters Patent.

Patented Oct. 5, 1909.

Application filed April 29, 1807. Serial No. 370,771.

' resident of \Vest Orange, county of Essex,

State of New Jersey, have invented certain new and useful Improvements in Pedal Mechanism, of which the following is a specification.

My improvements relate to automatic means for raising and lowering or for doing either one of these operations in connection with the pedals of a musical or other instrument in which the pedals are adapted to be tclescoped or made to disappearwithin the instrument, and further relate to means for controlling the fall of said pedals as same are lowered.

In the. accompanying drawings which illustrate certain specific embodiments of my improvements, Figure 1, is a front elevation of an instrument showing the pedals thereof partially cut away and provided with my invention; Fig. 2 is a vertical sectionpartly in elevation on the line 2-2 in Fig. 1; Fig. 3 is the same as Fig. 2 with theexception that the pedal is shown in its released and raised position and the related parts positioned accordingly; Fig. .4. shows the same parts as Fig. 3, but with the door raised and the pedals' and related parts telescoped or elevated within the instrument; Figs. 5 and 6 are views corresponding respectively to Figs. 3 and 4 but showing in addition to said figures automatic means for elevating the pedals within theinstrument; Figs. 7 and 8 are enlar ed views analogous to Figs. 5 and 6, but di er in showing difierent means for checking or opposing the fall ofthe pedals; ig. 9 1s a view in elevation and in section of the parts shown in Fig. 7 as the same would appear on a plane passed through 9-9 on that figure looking in the direct-ion of the arrow; and Fig. 10 is -a copy of the right-hand portion of Fig. 9 with the exception that the stop mechanism is shown in different position.

Describing now my improvements by reference to the s ecific embodiments thereof shown in the rawings and of which the novel features will be pointed out in the claims, 1 is a wall of the case of an instrument, in this instance the front wall of the case of a piano-player, having pedals 2 adapted to be raised and lowered through an opqhiing, hereinafter called the pedal-open- .h'austing be ing, in said front wall of the instrument and which opening is controlled by a door 3.

The particular form of door shown consists of two superposed sections hinged together by their transverse abutting edges and with the top of the first section hinged to the case of the instrument. The door is operated by a cord 4, secured to its lower section at 5, and extending u within the instrument over a guide or pul ey 6 and out through an opening in the case of the instrument, where the cord terminates in a handle 7. Pulling the handle 7 will obviously raise the door by folding two parts on each other into the position shown in Fig. 4:. To guide the lower section of the door, projecting ins 8 are provided one from each side 0 said lower section. 1 These ins travel in grooves 9, formed in the side-edges of the instrument next the pedal opening.

The pedals 2 are su ported by and operatively connected wit what maybe called pedal supporting arms-10, one on each side, as best shown in Fig. 1. In the specific devices illustrated, the pedals are thus supported by and connected with the arms 10 by means of pivotal connections 11 between the bottom edges of the respective pedals with a rod 12 which rod is secured between two feet 13, which latter in turn are secured, each to one of the arms 10. The

pedal supporting arms 10 are pivoted at their other ends within the instrument, so that they may be'raised and lowered into and out of the instrument and in this particular case are pivoted at 14 to angle irons 15, which in turn are secured to the stationary board 16 of a bellows 17. -,In the specific devices shown, the bellows 17 is in tended to represent the main 0 crating bellows of a mechanical player and is operated from the edals 2. .For this purpose each of the pe' Me is operativel connected with the movable board 18 o the bellows by means of an operating arm 19 pivotally secured at one end 20 to the pedal andat its other end 21 to a right-angled lever 22 on the movable board 18' of the bellows. The

bellows 17 being as statedone to operate a mechanical layer is in consequence an'exllows and consequent-l has an exhaust valve 23 which permits t e escape of the air contents of the bellows when the same is contracted, but which .is closed and seals the bellows, when same is expanded.

" thus far supporting arms and related parts auto in Fig. 8.

' parts elevated inside the instrument.

matieally from the operation of a door, 6. g. the door 3 controlling the pedal opening in the instrument. I will accordingly proceed to describe the automatic means shown for accomplishing these functions.

The automatic means for elevating the pedals from the raising of the door comprises (see Figs. 5 to 8 and especially Figs. 7 and 8) a pair of lifting rods 24 located up rightly within the instrument and connected pivotally, each by its 'lower end to the resppctive pedal supporting arms 10 at 25. The upper ends of the lifting rods 24L are each reciprocatingly guided in stationary sleeves 26 (see Figs. 5 and. 6) .or in swivel sleeves 27 (see Figs. 7 and 8) mounted inside the instrument. Pivoted at 28 on each of the lifting rods 24:. is a stop 29, disposed end-wise to the plane of the pedal opening and projecting forward toward said opening so that the door 3 in the act of raising it will catch under said stop 29 as shown in Fig. 7 and will thereby act through the lifting rod 24 to elevate the pedal supporting arms 10 together with the pedals and other related partsint'o the position shown To prevent the pivoted-stop 29 from swinging on its pivot 28 during the act of raising the pedals by the door as described, a lug 30 is provided on-each stop projecting from the stop behind each lifting rod24.

As the door 3'is elevated, carrying in contact with it the stops 29 and elevating the pedals as described, it will be noted froma comparison of Figs? and 8 that on account of the in-swinging of the lower end of the rods 24, the stops29 on said rods will gradually move away from the supporting edge of the door3, until (the parts being so designed) said door is raised sufiiciently far to completely elevatethe pedal parts, when the sto s 29 will be entirely clear of the door. ence the door is free to be raised still higher for a purpose later on to be described. The door operating cord 4 may now be'released to drop the door, thereby closing the pedal opening with all the pedal Thus a simple pull on the cord 4, when the pedals are down in playing position, acts to raise the door and at the same time automatically elevate the medals .into' the instrument, and

of movement of the door 3 so that when sa1d door is sufliciently raised, it will strike said pivoted arm 31 and cause its lower end to upper end projects forward within the ran e press forward and-by contact with the pedal I parts, throw them forward out of their elevated position and start' them to fall through the pedal opening. In this particular construction the lower end of the pivoted arm 31 strikes against the cross rod 12 of the pedal parts to throw them forward as explained above.

Assuming that the pedal parts are in elevated position within the instrun'lent and it is desired to lower them into playing position, it ,will be apparent from the foregoing that it is only necessary to raise the door 3 until it strikes against the start said pedal parts to fall through the pedal opening and which thereafter continue to fall by their own weight into playing .position. In other words, a simple elevation of the door brings about an automatic lowering of the pedal parts.

I will now describe what may be calledse lective means, making it impossible for any one in raising the door for ply of elevating the pedal parts to at the same time operate the pivoted arm 31 of the pedal lowering means by raising the door too high. These selective means comprise in the construction shown (see particularly Figs. 9 and 10, also compare Figs. 7 and 8) a stop-bar 35 integrally secur in central position on a four-tooth ratchet wheel 36, which in turn is pivoted inside the instrument adjacent to the side-edge of the .pedal opening therein, so that when the stop-bar 35 is horizontal the end thereof will project beyond the sideedge of said opening into the path of the door and at a point where the door will strikensaid projecting end of the stop-bar 35 before it can contact with pivoted arm 31 of the pedal lowering mechanism. (See Figs. 8 and 9.)

Pivotally secured to the inside of the instrument, is..the pawl 37 adapted to coact with the teeth of the ratchet wheel 36 to prevent clockwiserotation of said ratchet wheel, in otherwords to prevent the projecting end of the stop-bar 35. when struck from below by the door in the act of raising it from being moved out of horizontal position (see pivoted arm 31 to' the purpose sim- Fig. 9). The projecting end of the stop-bar 35 therefore acts as a rigid stop to prevent elevation of the door beyond the point necessary to throw the pedal parts back .into elevated position. The doorcannot be raised higher and cannot contact with the pivoted arm 31 of the pedal lowering mechanism.

To provide automatic means-to withdraw the stop-bar 35 from its projecting position (Fig. 9) to permit the door to be raised high enough to operate the pivoted arm 31 of the pedal lowering mechanism, I provide a nose arm 38 having a pivoted nose-piece 40 adapted when struck from above to carry the arm 38 rigidly with it. and when struck from below to simply pivot freely out of the path of the object striking it without affecting the arm 38. This nose-arm 38 so constructed is pivoted at 39 tothe instrument so that its pivoted nose-piece 40 projects beyond the side edge of the pedal opening, whereby when the door is raised it will simply brush the pivoted nose out of its path without moving the arm 38, whereas when the door is lowered it will not only press the nose-piece out of its path but will also carry along with it the arm 38 about its pivot 39.

Connecting the arm 38 with the ratchet wheel 36 is a rod 40 secured at one end to the arm 38 and at its other end to a pivotally supported crank-arm t1. Pivotally mounted on said crank arni t1 and engaging the ratchet-wheel 36 is a pawl 42.

Normally to hold the nose 4:0 of the arm 38 extended in the path of the door is a spring 43 connecting the crank-arm 41 with any suitable stationary part of the instrument, as shown in Figs. 9 and 10.

Describing now the operation'in full of the selective means, it will be understood as explained above, that when the stop-bar 35 is in horizontal position (Fig. 9) its projecting end effectively stops elevation of the door above it, because of the engagement of the pawl 37 with the ratchet wheel 36. In other words it permits the door to be raised sufiiciently high to lift the pedal parts into their elevated position but not high enough to opcrate the pedal lowering arm 31. The door having been dropped into closed position, after the pedal parts have been thus elevated within the instrument, itstrikes' in its'fall against the top of the pivoted nose 40 of the arm 38 which as explained the spring 43 keeps normally extended in the path of the door. The effect of the door in its fall so striking the nose 40 is to swing the arm 38 about its pivot downward and thereby pull on the rod 40* to swing the crank-arm 41 and its pivotally carried pawl 42 likewise downward against the action of the spring 43. Since the pawl 42 is in engagement with the ratchet wheel 36, it by its movement compels said ratchet wheel to rotate in an anti-clockwise directidn and the proportion of parts is such that the swing of the arm 38 causes the ratchet wheel 36 td make a quarter turn. in other words, causesthe stop-bar 35 carried by said ratchet wheel move into the vertical position shown in Fig; 10. and consequently ontof the path of the door. The

door of course c'ont-inue's to fall after-striking the nose arm 38 until co'mpletely closed.

The pedal parts now being located within the instrument, when the door is next raised it will be for the purpose of lowering said parts into playing position, and this can be accomplished by the simple act of raising the door until it contacts with and operates the pedal lowering arm 31, which the door can now do because as explained, the previous lowering ofthe door has operated to move the stopbar 35 out of its horizontal projecting position into the vertical position shown in Fig. 10. The pedal parts accordingly fall through the pedal opening into playing position. The door operating cord t being then released, the door falling of its own weight will again strike against the nose lever 38 (which as stated isialways normally held in the path of the door by the spring 43) and by so striking said noselever gives the ratchet 36 another quarter turn in an anti-clockwise direction and consequently turns the stop-bar 35 from the vertical position of Fig. 10 into its horizon-- tal projecting position. In other words, the pedals are now down and the door closed with the stop-bar 35 in projecting position so that when the door is again elevated to telescope the pedals within the instrument, it cannot be raised beyond the point necessary to accomplish this result ;that is to say, cannot be raised to operate the pedal lowering arm 31.

The effectiveness of the selective means to make the simple raising of the door automatically selective either to raise or lower the pedal parts as may bedesired. will now be apparent.

To act as a check and control on the pedal parts as they fall from their elevated into their playing position I provide means as follows: Thus referring particularly to Figs. 1 to 6, I provide a connecting band 44, in this particular case an endless chain, connecting the pedals 2 with the pedal supporting arms 10. This band connection is such that it holds the pedals-against the pedal supporting arms in-the position which they occupy relative to each otherv when the pedal parts have been. elevated inside the instrument, andacts soto bind said pedals and arms together throughout the fall of these parts into playing position, as shown. in Fig. 2. The result is that the pedal parts do not fall suddenly but are checked and fall gradimiiy becausethey are op osed by the bellows 17 which fill and infl' e in the course of tliefill, as shown in Fig. 2; The

, pedal rods and pedals against the arms 10 the band 44 binds the rods '45 against the connecting band is adapted to be then released to permit the pedals to be operated freely on the pedal supporting arms. For this purpose,'I so form the parts inclosed by the connecting band, that said band may be moved into another position on said parts less widely separated and where in' consequence the band will be loose enough to permit free operation of the-pedals relative to the pedal'supporting arms 10. Thus," for this purpose I may provide a rod 45 car: ried by each pedal and by which said pedals are adapted to be connected as explained above, to their supporting bars 10 by a band 44 inclosing said rods 45 and said bars 10. Atthe upper part of the pedals (see Fig. '2) the inclose'd parts are so roportioned that bars 10 in the relative position which they occupy when the pedal parts are elevated. Below this position of the band (see Fig. i 2), the pedal rods 45 are inclined toward the bars 10 so that when the band is located at the bottom of the incline it incloses the parts so loosely that the edals can be freely operated relative to t e bars 10 to play the instrument. In the particular construction shown the connecting band 44 takes the form of a metal chain which has the feature 1 of dropping by its own weight when the pedal parts are elevated into the position shown in Fig. 4 where it will bind the pedal rods 45 and consequently the pedals 2 against the pedal "supporting arms 10. Moreover, said chain continues to bind the when the pedal parts are caused to fall and until said parts reach their playing position in Fig. 2 and-the pedals" are operated. In this way the fall of the pedal parts is cushi'oned and checked by the inflation produced thereby of the bellows l7. 1 When the pedals2 are pressed by the feet to begin playing. the instrument, the first downward pressure causes the chain 44 to slide by its own weigl1t down the incline (Fig. 2) of the parts it surrounds, into a position at the bottom-of th'e incline in the pedal rods 45 in which position as previously explained, the pedals are freely operative to play the instrument. When the pedal parts are again elevated within the instrument the chainas before automatically. descends into its binding position, ready to act the next time the pedals are lowered to check, control and cushion their fall with the bel: lows 17.

As either a separate or additional fall- "control means, I also show spiral springs 46 (see Figs. 7 and 8) located at the pivotal connection of the pedal supporting bars .10 with the anglearms, 15, with their free ends ,47 and 48 hooked respectively under the bar 10 and the angle iron 15.

When the .pedal parts are allowed to'fall from their elevated position in Fig. 8, the springs 46 act to oppose and counterbalance the weight of the pedal parts and therefore to check the suddenness and violence of their fall. Moreover when the pedal parts are being elevated from their playing position in Fig. 7, these springs 46 have the additional function of assisting said elevation, since they constantly actin the direction of elevating the pedal parts. Less pulling effort is therefore required to be exerted on the door-operating cord 4 to raise the door and from it the pedal parts as heretofore explained.

In combination, a pedal-supporting member adapted to be raised and lowered through an opening in an instrument; a bellows; a pedal carried by said pedal-supporting member and operatively connected with said bellows; and a releasable band connection between the pedal and the pedalsupporting member adapted to bind them together in the position relative to each other which they occupy when the pedal and its supporting member have been raised into the instrument.
