TIME-CONTROLLED STARTING MECHANISM.

To all whom it may concern: 7

Be it known that 1,.F RANOESCO CIRELLI, a subject of the King of Italy, residing at Philadelphia, in the county of-Philadelphia and State of. Pennsylvania, have invented certain, new and useful Improvements in Time Controlled Starting Mechanism, of which the following is a specification.

One object of my invention is to provide means for automatically starting sound reproducing machines at any predetermined time so that the sound reproduced can serve as an alarm, for example, instead of the ordinary alarm clock bell and in this manner a person can be awakened with music from the machine instead of a noise such, for eX- ample, as by an alarm clock bell.

Another object is to include in my inven-,

tion means which will permit a record placed on the machine to attain, its proper momentum or number of revolutions per minute before the sound transmitting means is broughtinto engagement therewith. In this manner the machine will start playing at the'proper andintended pitch of tone.

A further object is to so construct my invention that the record or any of the sound transmitting parts cannot be injured due to theautomatic starting of the machine.

Another object is to so construct my invention that the record will be automatically stopped after having been played. These objects, and other advantageous ends which will be described hereinafter, I attain in the following. manner, reference being had to the accompanying drawings in which' i Figure 1 is a front elevation of a sound reproducing machine equipped with my in- "vention; certain of the parts being shown ofthe parts during theoperation of my invention,

Referring to the drawings, 15 represents a sound reproducing machine cabinet hav mg a top board 16 which is mounted below the top edge 17 of the cabinet so as to provide a space 18 for a record-supporting turntable 19 which can'be rotatedby a motor within the cabinet (not illustrated).

A tone arnr20 is mounted on the top board 16 and supports a soundbox 21 havng a needle holder 22 for the record-engaging needle 23, said tone arm being pivotally mounted so as to swingin horizontal and vertical planes and so that the sound box has a similar movement.

The cabinet 15 hasa chamber 24: below the top board 16 and this chamber is normally closed in the front by hinged doors 25. I mount 'within the chamber 24 an alarm clock 26 which may be of any construction which has a shaft 27 which rotates at a predeterminedtime due to the setting of the clock. i

I secure an arm 28 on the shaft 27 of the clockwhic'h, when the shaft rotates, is adapted to strike against a depending L- shape stem 29' on a bar 30. The bar 80' is adapted to slide in bearings 31 mounted on the top board16,and a slot 32 is provided m'said top board to allow the stem 29 to I depend into the chamber 24 and within the g Patented July 6, 1920.

table and permits the latter to be rotated by its motor. It will thus be understood that when the bar 30 is moved in the direction of the arrow 00 the lever 34 will be moved to start the rotation of the turntable 19.

I mount on the top board 16 a housing 35 so that said housing is fixed with relation to the top board. This housing includes a bridge 36 provided with a tapped hole 37 into which is adapted to fit a thumb screw 38.

A slidable member 39 has an extension 40 adapted to fit within the housing 35 and slide longitudinally therein. The thumb screw 38 serves to engage the slida-ble ment ber 39 and thereby secure the same to the housing in various longitudinal positions.

A head 41 is provided on the member 39 and has a post 42 adapted to form the pivot for a support 43. This support 43 has a hole 44 which fits over the post 42, and a headed screw 45 is adapted to prevent raising movement of the support from the post 42.

The support 43 has an angularly disposed slot 46 into which fits an L-shape hooked. end 47 of a link 48; the opposite end of said link being loosely fitted within a hole 49 in one end of a double ended lever 50 which is pivoted between its ends on a post F1 secured on the top board 16. The opposite end of the lever 50 is connected by a link to the lever 34.

The support 43 has at its end opposite the slot 46 two projecting fingers and 54 and a. lip 55 so arranged that the finger 54 is located between the finger and the li 55, a detail of this construction being clearly shown in Fig. 6. ,Either of the fingers or 54 is capable of supporting the needle holder 22, according to the size of the record, so that the needle 23 when the needle holder is so supported will be out of engagement with the record 56 upon the turntable 19. The parts are so arranged that the fingers 53 and 54 and lip 55 occupy a plane slightly above the edge of the record and turntable.

Considering that the needle holder 22 is resting upon the finger 54, as shown in full lines in Figs. 2, 3, and 5, and that the end 47 of the link 48 occupies a space between the ends of the slot 46: when the arm 28 of the alarm clock starts to rotate, it will engage the stem 29 and move the bar 30 longitudinally to cause the anti-friction roller 33 to move the lever 34 into a position to release the turntable 19 and permit it to rotate. This movement of the lever 34 will turn the double ended lever 50 on its pivot 51 through the medium of the link 52 and such movement of the lever 50 will cause a longitudinal movement of the link 48. However, this longitudinal movement of the link 48 cannot move the support 43 on its pivot until the end 47 of said latter link engages the end of the slot 46. In other words, there is lost motion between the link 48 and the support 43 and during the time required to move the end 47 into engagement with the portion of the support 43 which forms the end of the slot 46, the turntable will attain its proper momentum or speed. Just as soon as the link end 47 engages the end of the slot 46 the support 43 will be turned on its pivot so that the finger 54 will be moved from under the needle support 22 and, due to the beveled upper surface 57 of said finger 54, the needle holder will slide therefrom and permit the needle to engage the upper surface portion 58 of the record 56, said portion being to the outside of the initial playing groove so that there is no possibility of injury to the record due to the lowering move ment of the needle into engagement with the record.

The lip 55 is so arranged that after the needle 23 has engaged the portion 58 of the record, said lip 55 will push against the needle holder 22 to slide the needle 23 into engagement with the initial playing groove of the record. Thus the needle will gently engage the record and the initial playing groove thereof and since considerable time elapses between the initial movement of the starting lever 34 and the final pushing movement of the lip 55, the turntable will have ample time to attain the proper speed. before the record starts playing.

I prefer that the machine be automatically stopped after having finished playing the record and I may employ any form of automatic stopping mechanism for this purpose. However, in the drawings I have illustrated an automatic stop 60, such as covered by my United States Patent 1,208,749, December 19, 1916, and I provide the tone arm 20 with a pin 61 or other projection adapted to engage and operate the stop after the record has been played.

The position of the support 43 relative to the record can be changed by moving the slidable member within the housing to accommodate variations in the size of the record. Also, the finger 53 serves as an auxiliary finger which can be used to support the needle holder 22 in the same manner as above described in connection with the finger 54. For example, the auxiliary finger 53 could be employed when a record or machine of different diameter is used and between these two fingers 53 and 54 and the adjustment of the slidable member 39 my invention is applicable to records and ma chines of various types and sizes. It will be noted that when the finger 53 is used to support the needle holder, then the finger 54 will act to push the needle into the initial playing groove of the record in the same manner as above described in connecabove described to permit the proper ad justment of the parts so as to provide a dwell of the support 43 until the turntable has secured its proper speed.

lVhile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by LettersPatent is:

1. The combination of a record, means for moving said record; means movable to effect the movement of said record by said first means; sound transmittin means for engagement with said record; a support for holding said sound transmitting means out of engagement with said record; and time controlled means initially operative to actuate said second means to start the record and afterward operative to move said support into a position to permit said sound transmitting means to engage said record;
