QDBIAN CLIFFQRD BALSON, OF PHILADELPHIA, PENNSYLVANIA.

CONTINUGUS PLAYER FOR TALKING MACHINES.

Application filed January 12, 1921.

To all whom it may concern:

Be it known that l, ADRIAN CLIFFORD Banson, a citizen of the United States, residing at 663 Preston St, Philadelphia, in the county of Philadelphia and State of Pennsylvania have invented a new and useful Continuous Player for Talking Machines, of which the following is a specification.

My invention relates to improvements in a continuous player device for talking machines in which alternating sound boxes and needles operate in conjunction with a supporting tube with a. number of collars or sleeves thereon, needles and sound boxes being caused to engage alternately the talking ma chine record by means of a counter-balancing weight, the movement of which is controlled by a circular governor placed on the center of the record. The objects of my invention are first to provide a needle continuously in contact with the talking machine record; second to afford facilities for the proper adjustment of the device whereby records of different diameters may be played by a continuous talking machine player; third to provide means whereby a trigger pin upon its coming in contact with the bevelled edge 01 circular governor when the record is entirely played, will throw the counter-balancing weight over, thereby liitting the needle oi one sound box oil the record and placing the needle of the other sound box upon the record at the beginning thereof.

I attain these objects by the mechanical illustration in the accompanying drawings in which,

Figure 1 is a front view of the machine.

Figure 2 is a view of the machine as it appears looking down upon it with the tone arm broken off.

Figure 3 is a side view of the machine looking towards the center of the record with one needle in play and the trigger pin about to throw the counter-balancing weight, litting the needle from the record.

Figure a is a view of the circular governor looking directly down upon it, which is placed in the center of the record and, regulates the movement of the counter-balancing weight. t

Figure 5 is a side view of the other sound box looking from the center of the record outward with the needle not in play.

Similar numerals refer to similar parts throughout the several views.

In Fig. 1, 1 is the talking machine record showing one sound box needle engaged therewith. 2 is the circular governor. 3 is a sound box needle engaging the record 1. 4 is a small rod or trigger pin extending clownward from trigger pin sleeve 26 to which it is attached. 6 is a hole in the side of the circular governor 2, through which a headless set screw fastens the circular governor to the spindle oi the revolving table of the talking machine 7 is a rod or trigger pin extending downward from trigger pin sleeve 27 to which it is attached. 8 is the needle on the second sound box. 9 is the sound box sleeve on the supporting tube. 10 is a small screw fastened in sound box sleeve 9 passing through slot in trigger pin sleeve 26. Its purpose is to check the rotary movement of the said tri ger pin sleeve, therel y transmitting the pressure of the counter-balancing weight to the sound box needle. 11 is a square hollow tube which holds the two counter-balancing weight rods in proper alignment. 12 is a square rod that slides in 11. 13 is the band attached to the adjustment rack. 14 is the supporting tube which supports the whole device. This includes supporting the sound box sleeves and trigger pin sleeves. 15 is the opposite sound box sleeve supported by tube 14 17 is the spindle in the revolving record table. 1919 are two sound boxes. 21 is a screw with a large head running through slot in 20 an arm of adjustment rack and is screwed into sound box sleeve 15. 2525 are two collars tastened to supporting tube 14 to hold the same in place to prevent side-motion. 26 is the right-hand trigger pin sleeve that Works around the sound box sleeve 9 and is held in place by the small screw 10, which permits a rotary movement limited by the length of the slot through which screw 10 passes. 27 is the trigger pin sleeve on the left-hand side of Fig. 1. 28 is the counter-balancing weight on the right-hand side 0t Fig. 1. 29 is the counter-balancing weight on the left-hand side of Fig. l. 30 is a small rod which extends downward trom counter -balancing weight 28 and connects with trigger pin sleeve 26. 31 is a small rod which extends downward from counter-balancing weight 29 and connects with trigger pin sleeve 27.

In Figure 2, 5 is the tone arm broken off, which is of course not claimed in this application. 16 is a small pin passing through collar 25 and supporting tube 14, which pin is riveted at both ends and is for the purpose of preventing any side motion of 14. 18 is a little screw that works in the slot in the trigger pin'sleeve and holds the counterbalancing weights in place. 20 is anarm of the adjustment rack opposite 13. 21 is a small screw fastened to 15 working in a slot in the rack adjustment. 22 is a thumb screw to operaterack adjustment. 23 is a small screw to clamp the rack adjustment in place after proper adjustment. 24, 24, 24 are small screws with lar e heads that hold the rack in proper position.

In Fig. 3, 10 is a small screw fastened in sound box sleeve 9 passing through slot in trigger pin sleeve 26 and checks the rotary movement of the said trigger pin sleeve thereby transmitting the pressure of the counter-balancing weight to the sound box needle.

inv Figure a, 2 is the top view of the circular governor.

In Figure 5, all numbers are governed by the prior enumeration.

To understand the mechanism of this de vice it is necessary to place the record on the revolving table of the talking machine, ter which place the circular governor upon the center of the record so that the projecting spindle of the revolving table fits in the hole in the center of the circular governor, Figure l. When the record begins to revolve it revolves the circular governor. The needle on the right-hand side of the talking machine as you look at it from the front is then put in contact with the record and the sound proceeds to. come from the. sound box on the same side. As the record revolves the sound box needle forces the whole device, except circular governor, Figure 4, over towards the center of the record. When this sound box needle reaches the end of therecord, trigger pin 4 engages the bevelled surface of circular governorl igure 4;. The trigger pin gradually ascends the bevelled edge of the circular governor, and. when trigger pin t has ascended sufficiently high, it throws the counter-balancing weight in the opposite direction from that in which it was when "the right-hand needle began to operate. When this action takes place the right-hand needle is disengaged from the record and the needle on the left-hand side engages the record and that needle travels towards the center of the record upon the lines thereof until trigger. pinf'? engages the bevelled edge of circular governor Figure 4i, and the same operation is repeated on the left-hand side as above described for the right-hand side.

the right-hand side again engages the re:- 0rd and the operat1on s repeated. continuously until the talklng machine runs down Upon the counter-balancing weight being'thrown over, the sound box needle on or the revolution of the record 1 is stopped.

/Vhenit is desired to play a different sized record an adjustment is made by means of adjustment rack as shown in the drawing Figure 1,20, 22, 28, 24; and 13.

I claim: l. The combination, in a continuous player device for talking machines, of two counter-balancing weights, two sounding boxes with needles connected by a supporting tube attached at right angles to the tone arm of the talking machine horizontally above the. record with'two trigger pins attached to the supporting tube, and of a clr cular governor. which trips the counter-bah ancing weights when one of the trigger pins comes in contact with it, thereby throwing the needle of one sound box out of play and throwing the other sound box needle into play, substantially as set forth.

2. In a continuous player device for-talk ing machines the combination of a supporting tube attached at rightangles to the tone arm; of the talking machine and held horizontally above the record and two counterbalancing weights andtwo sounding boxes with needles and an adjustment rack, to make the device fit different sized records,

and also. the combination of a circular go'vernor placed'on the center. of the record and revolving therewith, two trigger pins attached to said supporting tube by means of sleeves in such a manner that when a trigger pin comes in contact with the bevelled surface of the circular governor, it trips the counter-balancing weights and throws the needle of one sound box out of play at the end of the record, and throws the needle of the other sound box into play at the commencement of the record, substantially as set forth. v p

3. A. continuous player device for talking machines with a supporting tube attached at right anglesto the tone arm of the talking machine held horizontally to the record and having attached to said tube two sound ing boxes and needles, two trigger pins,

two counterbalancing weights and an adjustment rack also placed on the center of the record, a circular governor, which governor revolves with the record and has upon its upper face a bevelled surface which gradually merges into a cam and isadapted to co-operate with the trigger pins to trip the counter-balancing weights whenone of the trigger pins has sufficiently mounted the bevelled surface and cam, thereby throwing the needle of one sound box outof play and throwing into play the needle of the other sound box at the commencement ofthe record, substantially as set'forth.

' 4. A continuous' player device for talking machines witha supporting tube attached at right angles to the tone arm of the talking machine held horizontally to the record and having attached to the said supporting tube two sound boxes and needles, two sound box sleeves, two trigger pins, each fastened to a trigger pin sleeve, two trigger pin sleeves working around the sound box sleeves, one or more counter-balancing Weights, an adjustrnent rack and a circular governor placed in the center of the record, having on it a bevelled edge which gradually turns into a cam, whereby the counterbalancing weight'or weights are positively tripped when one of the trigger pins has mounted sufliciently this bevelled surface and cam, throwing the needle of one sound box out of play and throwing into play the needle of the other sound box at the commenceinent of the record, substantially as set forth.

5. In a continuous player device for talking machines the combination of a circular governor adapted for arrangement centrally on a disc record, a pair of inter-connected counter-balanced rocking sound boxes and a pair of trigger pins operating connectedly with the pair of sound boxes and arranged to co-operate successively with the governor, substantially as described.
