To allwhomit may concern:

- Be it known that we, VINCENT PINTO and Josnen PiNro. subjects of the King of Italy, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and useful Speaking Clock, of which the following, ,is a s ecification. 1

ur invention relates to clockmechanisms which are interconnected with phonographs, so thatthe clock intermittently operates; the phonograph. r. 1 The purpose of our invention ,iszto make the connection between the clock, and the phonograph more positive and reliable. up i A further purpose is to causejror :per nit phonograph operation. preferablyby making electrical connections at predetermined times, maintaining the phonograph in:'operation positively during the intended time and stopping it quickly preferably by breal( ing the connections.

A further purpose is to support a phonograph operating switch or control by a cam, maintaining the switch or control in operative position thereby, While moving the cam in accord with the movement of the phonograph and opening the switch or control by withdrawing the cam support.

A further purpose is to simplify the connection of the phonograph with the clock.

A further purpose is to provide forautomatic, .quickand efl'ective return of the phonograph stylus to operative position ready for another cycle of operations.

Further purposes will appear in the specification and in the claims.

l'Ve have preferred to illustrate our in- -vention by but one form, selecting a form which is practical, efiicient, reliable and inexpensive, and which at the same time well illustrates the principles of our invention.

The clock 15 -;need have. no special form, except 'that'a shaft,-,h ere its ,main shaft 16 is intended to carry anarm or arms 17 upon which are mountedpperating devices here shown as two innumberylB and 19, by which the phonograph mechanism is'tripped. The

- two devices shown pnovide for halfhour announcementof the timaandthey may beincreased in numberto announce the quarter hours, for example, if desired.

At intervals these- devices 18 and 19 engage an arm 20 whose effective length is extended by an auxiliary arm 21 pivoted at 22 and restricted in its movement so that it can be turned'to the left in Figure 3, to such an extent only as to make its length lie approxi mately in line with the arm 20.

The arm 20 is pivoted upon a shaft 23, is extended at 24 beyond the. shaft and is bent at 25 to connect througha rod 26 with a rocked arm 27-. This arm is pivoted about a shaft 28 so that the extension 29 conveniently turned at 30 (so as .to more readily engage with the parts of the phonograph) will be lifted when the arm 20 and extension 21 are lifted. The parts are so weighted that the extension 29 and arm 20 fall by their own weight and the weight of the connected parts when the devices 18 and i9 release from the arm 20. At the same time the extension 21 swings to the right from its extended position to the position seen in Figure 3.

The extension of the lever arm 20 is effected to give a greater length to arm 20 than would otherwise be permissible because of the nearness of the shaft 16 and (possibly) other clock mechanism, and a quick release.

As we are looking at Figure 3 from the back the shaft 16 and hand 31 move in counter-clockwise direction in this figure with the result that the arm 20 will be lifted twice and the arm 29 will correspondingly be twice lifted for each rotation of the shaft 16. It will be evident that the bends and turns of the arms as well as the relative locations of the arms and their pivotal shafts will be determined in large measure by the room available and by the particular clock mechanism selected as it affects this room.

The lifting of the arm 29 lifts a connection 32, by which the switch lever arm 33 is lifted about its pivot 34 in fixed frame member 35.

The electrical connections for the motor are closed from a conductor 36 secured to frame through the pin 34, contact arm 33, contacts 37 and 38, arm 39 and connection 40 to a second conductor 41 so that the raising of the arm 33 by means of rod 32 closes the circuit by bringing the contacts 37 and 38 to gether. 'lVe insure a good rubbing contact between the parts by providing for some movement of the respective arms 33 and 39 after their contacts 37 and 38 come into engagement. e provide for the movement of arm 39 by pivoting it at 42 and springpressing it downwardly at 43. The limit of downward movement is taken care of by a pin 44 which engages the end 45 of a bracket which in this case forms the support for the arm 39 and also the electrical connection between this arm and the conductor 41.

Though the lifting of the arm 33 by clock actuation brings the contacts 37 and 38 together. it can not be depended upon to lift the arms to give rubbing engagement nor to hold them in engagement during an extended period of time. Even if this were relied upon it would not require operation for an exact number of turns of the phonograph record to insure complete delivery of the message and correct starting point for the next message.

In order therefore to relieve the clock of the strain of holding the arm 29 raised, to make it possible to raise it higher without requiring that this be done by the clock against the spring resistance of arm 39. in order to maintain the contact reliably during a predetermined period, measured by revolutions of the phonograph as distinguished from cloclr movement and to give a quicker hrealr of the connections (free from clock retardation) when the electrical circuit is to be opened, we supplement the clock closing of the contacts by phonograph control of the contact. This is done through a cam which may be made to lift the lever 29 higher than it may be desired to lift it by the clock, releasing the extension of arm 20 by reason of lirftingarm 20 and to hold arm 33 in lifted position during the extended period as measured by phonograph operation. During this period the clock support of lever 29 is withdrawn by disconnection of the devices 18 and 19 from the extension of the arm and the circuit may then be broken quickly and reliably by removing the cam support for arm 33 and allowing the'arm to drop.

We have preferred to use the cylinder form of phonograph on account of the greater compactness of the construction secured 'by it and We show the phonograph cylinder at 46, mounted in any suitable bearings and operated through a pulley 47 and belt 48 from a motor 49 suitably mounted. The motor is energized by closing of the contacts 37 and 38 and immediately begins to operate, so as to cause rotation of the cylinder 46. 7

Movement of the cylinder operates a train of gearing through shaft 50 upon which the cylinder is mounted, including gears 51, 52, 54 and 55 in train therewith mounted upon appropriate shafts, suitably supported.

One of these gears, here shown as gear 52,

carries a pin '56 which engages with one end i 57 of a latch arm 58 pivoted at 59 and spring retracted at=60. To give additional resilience to the operation, the lower part of this arm is reversely bent-at 61 to provide a spring contact portion 62 with which the pin 56 engages.

The latch end 63 of this latch arm engages with teeth 64 of a ratchet wheel 65 mounted upon any suitable shaft 66 and carrying a cam 67. This cam is provided with two ends 68 and 68' which have sloping cam surfaces 69, 69', rests or dwells 70, 70, and abrupt terminal edges or falls 71 and 71. The arm 33 is downwardly extended at its end at 72 to engage with the edge of'the cam surfaces successively.

With the construction shown, as soon as the motor is energized by partial lifting of the lever 33, the cylinder 48 starts to deliver its message and, through rotation of gears 51 and 52 and operation of the latch arm. the cam begins to turn. The slope 69 or 69' lifts the end of lever arm 33 so that the arm 20 is lifted. In the meantime, the device 18 or 19 is moved about to such a point that when the arm 20 has'been sufliciently lifted (either before the end 72 engages with dwell 70 or 70, or early in this engagement) the extension 2i will fall free from the device 18 or 19. relieving the clock of all further strain from the connecting mechanism and allowing the shaft16 and arm 17 to continue their travel without restraint until time for thenext electrical contact. The cam continues to operate lifting the nose 72, raising arms 33 and 39 and thereby ensuring good rubbing contact of 37 and 38; and this contact is ensured with maximum lifting of "arms 33 and '39 by final engageinent ofnose 72 with the dwell'70 or This maintains operation of the motor until the nose drops off the edge of fall 7 3 or 73 of the cam, atwhich'time the contacts 37 and 38 are interrupted and the motor stops, the parts -named remaining in stationary position 'until the next connection of the contacts 37 and 38 through the clock mechanism.

'The motor is operated 'by'current from a battery 74 and the speed is controlled througha rheostat, 75 as best seen in Figures 8"an'(l;10. "The rheostat arm 76 is shown as connected with one of the circuit conductors -77and the end of the resistance element 78 is cd iiiectedwith the other at'79. A switch '80 'isprovided to open the circuit completely when desired) 1 Asimplealternati've construction for operatinglth'e ratchet wheel 65 is shown in Fig. 9

in w ich the gear 52 is provided with holes 81, affording different points of connection for a pivot gain 82 forming a crank pin for operation 0 a link'83. "The link is pivoted at 84 to a pawl or latch 85 and-to a guiding arm 86 swinging about shaft 66. The pawl is controlled withrespect to the link 83 by a spring 83 'which pressesit in to a predeterminedextent. Pm 85' prevents the pawl from falling forward completely. As a result, the "'awl 85 engages with the ratchet teeth 64 uring the t me that the pin 82 is at the left hand part of its circle of movement and for different lengths of time according to the opening 81 in which the pin 82 is placed, thus giving an adjustment of the extent of operation of the ratchet wheel for each rotation of the gear 52. It will be evident that'this may be made to give comparatively rapid rotation of the ratchet wheel and cams, corresponding to short messagesupon the phonograph record.

It will be evident that the duplication of the cam surfaces is forthe purpose merely of requiring less rotation of the ratchet wheel to accomplish the desired cam function, and that a single can] or any number of cams desired maybe used,'allowing discretion in design in this feature as in all other features of the constructions shown, and not restricting to the exact construction in view of the teaching of the invention herein.

The phonograph shown is a conventional one, having a sound box 87 horn 88 and any suitable governor 89. The sound box is carried by an arm 90, pivoted at 91 and is guided along a bar 92 upon which it is held by a latch 93. Movement of the stylus arm is controlled by a feed screw 94 and half-nut 95, by which, with normal operation of the machine, the gear 53 turns the thread 94 in a counter-clockwise direction in Fig. (i, so as to advance the nut, and hence the stylus, to the right in Fig. 4, reproducing the record which may be upon the cylinder.

The half-nut 95 is pivoted about a center at 96 and is held in place by a spring 97, upon any fixed support. The arm 98 carrying the half-nut is extended at 99 to the left in Fig. 7, terminating in a resetting latch 100. At the opposite side, arm 96 is rigidly connected with an arm 101, engaging the end 102 of alever arm, operating as a rocker arm, which is pivoted at 103, and whose opposite end 104 is adapted to lift a plate 105 by which the stylus is supported at the left end Fig. 7, the stylus being pivoted at 108 in that figure. The pivot 103 is supported in the supporting bracket 109, movable with arm 90.

With movement of the stylus bodily in the direction of the arrow in Fig. 4 under the influence of the feed screw 94, with repeated announcements by the phonograph, the latch 100 is finally brought within the ath of movement of a pin 110 upon a co lar 111 carried by return screw 112 which is rotated in a. counter-clockwise direction (Fig. 6) by the gear 55. This pin 110 engages beneath a shoulder 113 (Fig. 12) in the latch 100 lifting the latch and moving it toward the left in Fig. 7 (the right in Fig. 12) so that the rib 114 will engage with and, because of the shape of the parts and direction of the latch, will be held in contact with the threads 115 of screw 112. In the meantime the lifting of the latch has lifted the end of arm 99, lifting the halfnut 95 free from the feed screw 94 and the resultant downward movement of arm 101 has moved arm 10:? downward and lifted arm 104. lifting the stylus and leaving the entire reproducing mechanism free to be reset by the return screw 112. This therefore causes reverse travel of all of the parts which are movable longitudinally of the record cylinder. The movement continues until an arm 116 wedges the latch 100 out from its engagement with the threads 115, permitting the half-nut to again engage the feed screw.

The arm 116 may be set adjustably in a support 117.

The reversal can be designed to take place in connection with one of the ordinary half hourly or quarter hourly announcements, where these are long, by cutting short the announcement or may take the place of the announcement, using the time of motor operation which would ordinarily be utilized for the announcement for the purpose of setting the parts for return movement and moving them in position to start again.

It is obvious that the regular clock actuation, to cause-hourly, half hourlyor quarterly announcements can be superseded by adjustable actuating mechanismsfor giving an alarm, utilizing the rest of our invention unchanged except as to the announcement or record to be given, and that the only changes required forlsuch an alarm would be in the positionor character of the actuating devices, .forming part of the connection between thegclock and the lifting mechanism. We therefore contemplate including heneiniall such features as are capable of use .with actuation for alarm-purpose, with equal application to interval announcements andalarmst V w 1 -We desire, Ito include withinourclaims all those forms, of .our, invention which will suggest themselves. to other designers in the sametant iniviexv of ,our disclosure herein and which come within the reasonable spirit and scope-015.0111 claims. c
