CONTROLLING DEVICE FOR AUTOMATIC PLAYERS.

SPECIFICATION forming part of Letters Patent No. 769,013, dated August 30, 1904;.

Application filed March 14:, 1903.

To all whom, it may concern.-

Be it known that I, ALBERT D. PALMER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Controlling Devices for Automatic Players, of which the following is a specification, reference being had to the accompanying drawings,forming a part thereof.

The purpose of this invention is to provide an improved means for controlling the action of a mechanical motor used for actuating the perforated rolls of automatic players for musical instruments for the purpose, first, of arresting the action without losing the speed of the train, so that when started again the roll shall without sensible delay acquire the full speed which it had before stopping, and, secondly, to overcome a defect in the motors to which my improvement is applied, which as heretofore constructed do not start for rewinding when the controlling-handle is turned in the direction for rewinding until such handle is turned far enough first to disengage the winding -train and then, in addition, far enough to effect engagement with the rewinding-train, the result of which is that an insufficient turn of the controlling-handle in the direction for rewinding disappoints the inexperienced operator because the machine still continues to run in the direction for winding.

My invention consists in the devices shown, described, and specified in the claims for accomplishing these purposes.

In the drawings, Figure 1 is a plan of a motor having my improvements connected with it. Fig. 2 is a section at the line 2 2 on Fig. 1, showing the parts in position for winding at controlledspeed. Fig. 3 is a section at the line 3 3 on Fig. 1, showing the parts in position for stopping the running while the train is adjusted generally for winding. Fig. 4 is Fig. 6 is a Serial No. 147,770. (No model.)

section at the line 6 6 on Fig. 4:. Fig. 7 is a detail showing the operating-handle thrown into position for winding.

The general construction of the motor herein shown is one that is familiar, andI will describe it only in so far as necessary to the understanding of my improvements. From any source of power, which I have not illustrated, the wheel 1 derives motion in the direction shown by the arrow, which is communicated through the intermediate wheels 4, 5 on the shaft 6 to the wheel 7 on the oscillating bearing plate or lever 8, and by the last-mentioned wheel either to the wheel 9 on the windingroll shaft 10 or by the wheel 11 to the pinion 12 on the rewinding-shaft 13, the direction of rotation of the two shafts being, as will be observed, opposite, and the one or the other being rotated according to the adjustment given to the oscillating bearing plate or lever 8, throwing the gear 7 into mesh with one or the other of the gears on either side of it. For convenience of reference to the parts the wheel 9 and its shaft 10, although but a single element, will be referred to as a windingtrain, and the wheels 11 and 12, with the shaft 13, as a rewinding-train, and the wheels 1, 4:, 5, and 7 and their respective shafts are called the main train. On the shaft 6 there is also the worm-wheel 6, which meshes with the worm 14 on the vertical governor-shaft 15, communicating motion thereto at the rate of one revolution of the governor-shaft for each tooth of the worm-wheel.

The lever 8 is shifted about its fulcrum, which is the shaft 6, to throw the gear-wheel 7 into mesh either with the wheel 9 or the wheel 11 for the purpose of winding or rewinding as required. For thus shifting the lever there is provided a rock shaft 16, extending fore and aft and journaled in a bracket 17, and having at its rear end a cam 18, which as the shaft is rocked in one direction impinges on the pin 19, projecting from the lever 8, and forces that end of the lever rearward for effecting engagement with the gearwheel 11, a spring 20 being provided to retract the lever forward for effecting engagement. The distance between the two wheels 9 and 11 is such that the gear-wheel 7 at intermediate position can rotate freely without engagement with either wheel. The same rock-shaft 16 operates the devices for controlling the governor to regulate the speed, said 7 devices being particularly contrived with respect to regulating the speed during winding and adapted to permit a high speed up to the maximum during rewinding. These devices consist of a cam 21 on said shaft which operates a vertical shaft 22, adapted to be thrust longitudinally and also rocked in its bearings 23 23 on the bracket 17 the vertical move-.

ment being communicated by the cam 21 and the rocking movement by a disk cam 24, which is formed rigid, and, as illustrated, integral with the cam 21 on the rock-shaft.

The vertical shaft 22, has a cam-lever arm 25 projecting in a curved direction around the shaft 16, so as to be operated upon at its extremity by the face of the disk cam 24, for rocking the shaft in one direction. A spring 26, attached at one end to a lever-arm 27, at the upper end of a shaft 22, and at the other end to the lower part of the bracket 17 operates both to resist the upward thrust and to cause the downward return when the cam 24 permits, and also to resist the rearward rocking movement and cause the forward return when the disk cam 24 permits. The vertical rock-shaft 22 has a lever-arm 28, which extendsin direction to overhang the disk 29 on the governor-shaft, and at the end thus overhanging said disk it has a friction-finger 30, provided at the lower end with suitable terminal 30 for contact with the upper face of the disk to produce slight friction thereon. The governor-balls 44 tend by their separation under centrifugal action through the means illustrated, which are of familiar character, to lift the disk as the speed of rotation increases, and the contact of the disk with the friction-finger tending to retard the movement limits the speed according to the distance which the disk can rise before encountering the finger.

The cams 21 and 24 are symmetrically shaped from what may be called the middle point,at which the cooperating parts on the shaft 22 are in contact when the governor is held at rest, so that rocking the shaft in either direction gives the same movement both of vertical thrust and rocking action to the shaft 22, and said movement in either direction operates first to swing the lever-arm 28 forward, so that its friction-finger resting on the governor-disk operates to start the rotation of the latter in the proper direction, while almost simultaneously with such movement the arm is lifted, relieving the friction on the disk, so that its rotation commenced by the friction of the finger is continued by the motive power, and as the rocking of the shaft 16 continues in the same direction the frictionfinger being lifted higher and higher permits the speed of the governor to increase up to any desired limit short of the maximum which the motive power is adequate to cause.

As thus far described and as heretofore constructed the gear 7 is held normally in mesh with the gear 9 by the spring 20, so that the first movement of the iock-shaft16 in either direction, releasing the governor and permitting the train to start, wouldstart the winding-roll, and although the rocking action were in the direction suitable for ultimately throwing the gear 7 back into mesh with the gear 11 to start the rewinding-roll the rewinding action would not commence until the rocking in that direction had continued sufficient distance to carry thegear 7 out of mesh with the gear 9 and across the interval of its disengagement with both gears and into engagement with the gear 11.

One feature of my improvement consists in means for causing the rocking of the shaft 16 in either direction from the central or rest position to release the governor and start the main train without starting either roll, the

gear 7 being brought into mesh with either the gear 9 or the gear 11 only by continuing the rocking of the shaft after the governor and main train start, and another feature utilizing the same devices which perform the function above described consists of means by which the operator can instantly at will disengage the gear 7 while running from the gear 9, and thus bring the winding-roll to instant rest without arresting the governor or the main train and without bringing the rewinding-roll into action, so that the speed of the motor may be maintained and the rewindroll may be started again instantly at the same speed which it had when stopped, thus permitting interruption recommencing of the music without the short objectionable period of retarded tempo. My improvements for these purposes consist of a sleeve 32, sliding on the shaft 16, having a cross-arm 31, guiding it on the bearing-frame to prevent its rotating with the shaft, and having a thrustarm 34 extending rearward and terminating in position to operate upon the lower end of the lever 8 to force the latter rearward when the sleeve is thrust rearward. A spring 35, coiled on the shaft 16, stopped against the bracket 17, may operate at the forward end on the sleeve 32 to hold it forward to a limit determined by the rear end of the hub or sleeve 36 of the operating-handle 37; but this spring is not necessary and is only desirable for the purpose of keeping the sleeve forward against the hub of the handle when the lever 8 is thrust rearward for engaging the gear 7 with the rewind-train.

The forward end of shaft 16 receives loosely the handle 37, which is thus adapted to slide longitudinally on the shaft, and it is retained thereon by a screw 38 set into the shaft through a 'slot 39 in the hub or sleeve on the handle,

the length of the slot being suflicient to permit the movement hereinafter described. The end of the hub is provided at one side with a tooth 40, which has sloping sides, making it V-shaped, and the opposed end of the sleeve 32 is formed with two portions 41 42, which are straightthat is, he in planes at right angles to the axis and which are separated by a sloping portion 43. The portion 41 is in such position that the tooth 4O bears on it a little distance from the sloping portion 43 when the shaft 16 is in the middle position or position of rest, above described. At this position of the parts the sleeve is thrust rearward far enough to hold the gear 7 intermediate the gears 9 and 11 and out of mesh with both. Vhen the handle is turned in the direction to bring the tooth 40 to the slope 43 before said tooth passes off the straight portion 41, the rocking movement has released the governor sufficiently to permit the latter and the main train to acquire certain minimum speed, and when the tooth 40 reaches the slope 43 the sleeve is thrust forward by the spring 20 acting on the lever 8 to pull the latter forward to engage the gear 7 with the gear 9. It will be seen that the spring 35 also operates to move the sleeve in the same direction, but this is incidental and not material to the result when the arm 34 is not connected to but only bears against the lever 8. The winding-roll will thus start with a certain minimum speed which is calculated to be the slowest at which any music should be played. When the handle is reversed, the tooth 4O first encounters the slope 43, and the sleeve 32 is thereby forced rearward, causing its arm 34 to move the bearing-lever 8 rearward, taking the gear 7 out of mesh with the gear 9, bringing the winding-train to rest before the lever is at middle position and before the governor and main train are brought to rest, and while the rocking movement of the handle is continued further the tooth 40 still travels on the straight portion of the end of the sleeve 32 and keeps the gear 7 at intermediate position until the cam 18 reaches the pin 19 and operates the lever to carry said gear into mesh with the gear 11. The distances of these several movements may be such that the speed acquired by the train by the time the gear 7 is brought into mesh with the gear 11 for rewind may be as much greater than the minimum speed with which the roll starts as thought desirable.

It will be seen from the above description that during the running of the winding train and roll the tooth 40 is bearing against a straight portion 42 of the end of the sleeve 36, extending around from the foot of the slope 43, .and that a rearward thrust of the handle 37, sliding it on the square portion of the shaft 16, will thrust the sleeve 32 rearward, and that this movement may be employed to instantly disengage the gear 7 from the gear 9, and thus instantly stop the winding-roll. The limit of such movement of the handle rearward is determined by the slot 39, which will be onlylongenough to permit the gear 7 to be thus carried out of mesh with the gear 9 and not longenough to permit it to be carried. into mesh with the gear 11.

In use the operator or performer usually keeps his right hand constantly on the handle, so as to turn it in either direction to modulate the speed as required by the music, and he can thus without any change of grasp stop the playing by pushing the handle rearward at whatever position in its rocking movement it may occupy, and when he again allows it to return forward to normal position the music will be resumed at the speed at which it was interrupted.

The term train in the phrases winding-train and rewinding-t1ain is not inparts, but is used to indicate the part or parts, without regard to number, moving and resting with the roll, (winding-roll or rewindingroll, as the case may be.)
