Specification of Letters Patent.

Patented Aug. 13, 1918.

Application filed February 16, 1914. Serial No. 818,892.

'1'0 all whom. it may concern:

lie it known that l', NEWMAN H. llouiann, a subject of the King; of Great Britain, and a resident of West Orange, Essex county New Jersey, have made certain new and useful Improvements in Phonographs, of which the following is a description.

My invention relates to phonographs and more particularly to phonog 'aphs of the business or commercial type. It. has for its primary object to provide improved means.

whereby the reprodiiccr stylus of the phonon'i'aph can be. moved or spaced hack for the purpose of causing the repetition of any portion of the record whenever the operutor who is ii'tillHC-tll'itligf the record so dosires. I preferably attain this object by means of a construction wherein the re producing stylus can be shifted back over a part of' the record to repeat the same without the necessity of being lifted from. the. record, this construction greatly facilitating the rapidity and etliciency of operation of the back spacing device.

A further object of my invention is to provide unimproved construction wherein the controlling means for the hack spacing mechanism may be positioned at a conven' icnt position for actuation by the transcriber While the latter is operating the i' vptwlitlllg' machine. the preferred position for this purpose being adjacent the hov- Mv invention also coii1pi-isi -s certain details of construction which. will be hereinafter more fully set, forth.

The drawings illustrate one embodiment of my .invention, the same characters being used to designate the same parts in all. the

views. on said drawings Figure 1 is a rear elevation part-1v in section of said embodiment. of my invention:

Fig. 2 is'ui transverse vertical section taken oiitlie line. 2 2 of Fig. 1;

Fig. 7 is a perspective v lL'W U1 one or me elements of the back spacingmeans.

In the drawing, the numeral 1 designates a phonograph record. or blank which is rotatably mounted upon a frame or support In proximity to this record is an arm or traveling carriage '3 which supports a. pivoted frame 3 in which the recorder and reproducer are mounted. The rcproducer and recorder may he of any suitable construction, the numeral 4 designating the reprtfi diicer stylus which is adapted to 'track the grooves in the record 1. A suitable :toi-ni of reproducer is disclosed in my applicat-ion Serial No. 776,463 filed June 30, 1913, and entitled Phonograph reproducers. The. numeral 4 designates the stylus of the re corder. which may. if desired, be entirely omitted. A feed screw 5 is mounted in hearings formed in standards 6 which project. upwardly from the top of the table 2. A pulley 7. over which. runs a driving belt 8, operated by any suitable means. imparts rotation to the mandrel 9 through the maiidrel shaft (not shown). The mandrel carries the record or blank 1. The feed screw 5 carries a. gear 10 which meshes with a similar goal. (not shown) on the mandrel shaft wliercliiy rotation may be imparted to the feed screw in a manner well known in the plionogrraph art. T he feed screw courts with a feed nut 11 connccted'to the arm 3 to move the latter and the parts carried therein along the record or blank 1.

The arm and the structure supported therein is mounted to slide along a rotata hie back rod or rock'shaft- 13 and for this purpose the arm is provided with a hub 14 having an extension 15. the hub 14 and exon said rod.

slides 113011 a wide rod 15 runnin from one side of the machine to the other. The hub 14 is provided with an enlarged openin; or recess 16 for receiving certain elements hereinafter referred to. As shown in Fig. 1.. the extension 15 is of lessoutside diameter than the hub 14, a shoulder being this formed at the. inner endof the extension 15. Through a screw threaded openthe inner end of which projects into the opening or recess 16 and engages an 'aunnlar cain disk 18. which is mounted to more along the spindle 13 with the arm ing in this shoulder passe a small screw 17,

The inside diameter of this disk is slightly larger than the diameter of the spindle 13, and into the central opening through the disk projects a radially disposed pin 19 which engages a keyway extending along the spindle 13 substantially from one end to the other thereof. This pin causes the cam disk 18 to rotate with the spindle 13 Whenever the same is rocked, no matter at what point along the spindle 1.3 the cam disk may be, while at the same time leaving the cam disk free to slide along the spindle as much as necessary. On the face of disk 18 which is turned toward the screw 17, this disk is provided with a recess 21, one edge of which is abrupt or at right angles to'the face of the disk and the other of which is inclined to said tension '15.

face, as shown at 22 in Figs. 6 and 7. This recess receives the, projecting end of the screw 17 and the parts are arranged in such a way as to cause the disk to abut against the side of the recess through which the screw 17 projects and the inner end of this screw to rest against the abrupt side of the notch 21 when the disk'has its pin engag' ing the keyway 20 and the arm is moving along the record or blank 1.

With the above construction in View it will now be clear that if the back rod or shaft 13 is rocked in the direction shown by the arrows on Figs. Land 6, the arm 3 and the hub 14 and extension 15 being loose on the shaft and not engaging'the keyway 20 will not be rocked with the shaft 13, but the cam disk 18 will be moved so as to carry the inclined edge 22 of the recess over the Owing to the.

inner end of the screw 17. fact that the opening through the cam disk is slightly larger than the diameter of the rod 13, the first effect of this movement is to tilt or cant the disk from the position shown in Fig. 4 to the position shown in Fig. 5 in which latter position the cam disk binds or bites upon the rod 13, and cannot be tilted on the rod or pushed along the same any farther. If, however, the rod 13 rotates a little more, the inclined edge 22 of the recess 21 now has a cam action on the screw 17 and. produces bodily movement of the arm 3 through the huh 1+1 and the ex- This bodily movement carries the arm 3 to the right, as shown by the arrow in Fig. 1. and as the arm 3 is not lifted in the rocking of the rod 13, the stylus 4 is not lifted, but slides or skids along the record 1 until it again comes to rest in one of the sound wave grooves at a point which it has already passed. In. the operation of my invention, when the spindle 13 is released and moved back. to its original position, the cam Washer moves back with it and the parts resume the relative positions shown in Figs. 4 and 6. In this way, the stylus is spaced back to a position from which it is ready to repeat a part of the record. "Kcompression spring 23, encircling the rod 13 in the recess 16, engages at one end withthe cam disk 18 and holds it in position to act upon the screw 17 at all times, in the man ner above set forth.

When the arm 3 is'to be shifted back, it"

is necessary to disengage the feed nut 11 from the feed screw 5. For thispurpose, my invention comprises a part 24 projecting from hub 14 and having downtur'ned lugs 25 between which is pivotally mounted a lever 26. This lever 26 carries a spring arm 27 which, extends toward the screw 5, and carries atits outer end the feed nut 11, which engages the upper portion of the feed screw 5. So long as the threaded shaft 5 turns clock-wise, yiewing the same from the right on Fig. 1, the arm 3, with the parts carried/thereby, will be moved along the spindle 13 t0 the left, because of the-engagement of the feed but with the feed screw.

When the feed nut 11 is lifted from the feed screw, the arm 3 is free to.move backward.

A spring 29 secured at its upper end to the arm 3 presses downward upon the arm 27 and holds the feed nut against the feed screw, an adjusting screw 30 passing through the lever 26 from below and engaging the lower side of the spring-arm 27 to adjust the position of the feed nut with respect to lever 26 and feed screw 5. The feed'nut 11 is adapted to be lifted from the feed screw 5 by means of a disk-like cam 31 located inrecess 16 and mounted on rod 13, earn 31 having a pin 31' similar to. the pin 19 of the washer 18 to-engage the keyway 20. This cam is engaged by the spring 23 and .forced by it against the side of the recess 16 opposite that occupied by disk 18. One side of the lever 26 overlaps the edge of this recess In order to permit rocking or rotation of.

the rod"13 through a sufiicient angle to operate the" canr31, to free the arm from the The cam 31-slides with the feed screw 5, and to operate the disk 18 to shift the arm 3 backward, I mount the rod 213 in bearing blocks 32, secured in the upper ends of the standards 6and provided with bores which receive journals or trunnions 33 at the ends of the rod 13. I also secure to one end of the shaft an operating arm 34. which is fixed thereon so that when the arm is actuatedfthe shaft 13' must rock.. This arm is engaged by a spring 35, which is so as to keep the keyway 20 on the under side of the shaft and the feed nut 11 in engagement with the feed screw. In order to provide means for moving the arm 34 and rockving rod 13, l etmnect the said arm to the armature of an electron'iagnet, which is in circuit with a suitable souree of electricity, the circuit being adapted tobe closed to one ile the magnet; wheneverthe operator desires. This armature provided at its upper end with a. member 36 said member having an ehmgated slot 36 containing a pin 3-1t' on arm 34:. The armature is shown at 37 supported to extend upward from a suitable pn'ot 31 H] a frame 38 on the table This frame also carries the core 39 and coil 40 in position to attract the arn'iature 37; and also StClll'ttIl to this frame 1s an upwardly extending spring arm 41, having a cushimi. 4'2 on its upper end to act as a lmfl'erfor the member 36 and prevent the spring 35 from moving the arm (rt-t beyond vertical position "when the armature .is not att 'acted by the n'iagnct. supplied with current from the suitable The magnet is source of electricity, such as a. battery 43, and the circuit is arrangcd'to be opened and closed by means of a switch 44'. ferred coxjistructio'l'i forthis switch is dis- .r losed and claimed in my copending application, Serial No. 818,894 filed Feb. 16, 1914, v

on which Patent No. 1,214.!)20 was granted to moon l ebruary ti. 1917. i

The follmving a description of the operation of my invention. The drivil'ig mechanism for the phonogaph being set into o a-rati'on", the stylus i will run' along tlnrough the grooves in the l'tILO'l'tl l in the,

. manner required to accurately reproduce the Lou record. If, however, the operator should fail to tmderstand fully any part of the record and for this or any other reason should desire to have a part of the regord repeated, it Is only not .ssary to close the switch 44 to produce tl s result. switch emrrgizes the coil -10 which thereupon attracts the armature 37 and causes the same to swing the arm 34- to the right, yiewing the apparat us as slur-vii in Fig. 2, the arm 3% rotating the shaft 1 i hrough a certain angle. 'l'ln'ough the keyw'ay 20 in the shaft 13. the cam 31 is rotated to press down the rear end of lever :26 and raise the feed nut it from the feed screw fl. At the same time. the shaft rotates the cam disk: 18. with the result: that the cam disk is first tilted because of the acl-IOH of the cam surl'ace 22 on the mmu end of the screw 17 into binding engagement.

The parts are so designed that the binding of the disk 18 on the rod 13 takes place before the rocking of the rod 13 by the arm 3 t finished. Since the arm 3 is not i aised shifting the arm 3 and (parts carried thereby along the recordis irectly actuated O1 energized by the electrical means comprise ing the magnet 40 and its armature 37, as distinguished from being controlled in its action by such electrical means. The switch 44 then reopened whereupon the magnet releases the arnii'tture 37 and the spring rocks the arm 34. back to vertical osition causing the member 36 to abut agan'ist the cushion 42 on, the spring arm 41. The rotation of the arm. 34 causes the rod 13 to return to its normal position, the feed nut 11 being thus moved back into engagement with the feed screw 5 and the cam disk 18 assuming the position shown in Figs. 1 and 6. The apparatusis now ready to repeat a part of back is instantaneously effected by pressing upon the switch 44, which may beautomatically opened, as by a spring 45, when the pressure thereon is removed. The stylus is spaced back a given amount each time the switch is closed. If the stylus is not s jiaced back far enough upon oneclosm'e of the switch, the necessary amount of back spacing can be obtained by closing the switch a number of times.

From the above description it, will be seen that my invention is simple ai'id'thiilt it will operate with quickness, ease and certainty to produce the required effect, at any point in the rem-(alliedion otthe record. the cam disk 18 and the cam 31 moving along with the arm 3 and being capable of being operated instimtaneously. regardless of the point over the surface thereof is an important fea ture of my invention, the efficiency and simplicity of the apparatus-being thereby increased.
