INVENTOR gangli/13 May? ATTO R N EYS Patented Jan. 26, 1932 r stares PATENT ori-Ice GRAMOPHONE Applieatonieil October 16, 1929, Serial No. 400,031, and in Great Britain October 25, 1928.

rlhis invention. relates to gramophones and refers more particularly to gramophones of the kind having automatic means for discharging 'spent needles and replacing them by fresh ones, the present invention relating particularly to a new or improved construction ofmagazine for holding the needles.

A needle magazine constructed in accordance -with the present invention comprises a 1i IO'box like casing. having a hinged or movable side so that a needle package containing a row of needles arranged in parallel relationship can conveniently be placed in position, the magazine also including means for position- 315 ing the needle pack'age,.means for guiding the' row of needles and spring means for feeding the `row of needles and an ejecting plunger for ejecting the end needle of the row from the magazine into a needle holder.

- The box like casing may be made in two halveshinged together and a base or magazine'V carrier may be provided for receiving .the magazine proper, the base orcarrier having means for retainingthe magazine in its 'proper' relationship thereto.

The positioning means to position the needle package within the magazine may -include pinswhich register with openings inthe needle package and may also include a spring pressed plate exerting pressure on one side of the needle package. f

The means for feeding the row-of needles towards one end may take vthe form of a spring drum and flexible member connected to a pusher, and the pusher may be provided with a finger piece so that it can be withdrawn by hand when an empty needle package is to be removed and a fresh one inserted. In connection with needle magazines for gramopliones, the gramophone is Vprovided with means for operatingfa plunger on the magazine, and a furthery feature of the present invention consists inl providing ya device automatically to sever themechanical connection between the plunger operator and the plunger when it is desired to remove the magazine for recharging or for any other purpose. H

The means for severing the mechanical are Y connection between the plunger operator and the plunger may be actuated from a locking lever or member which is employed to retain themagazine in its base or carrier.

Figure 9 is a section on line 9-9 of Figure 5, showing the magazine only.

Figure 10 is a perspective view showing a needle package suitable for use in the magazine illustrated.

In the construction illustrated, the magazine comprises a body 1 and a hinged side 2 attached to the body by the hinge 8.

The

parts

1 and 2 are both of somewhat box like form, the back of the part l being closed by a plate 4 retained in position by screws 5.

The body 1 is provided in its face with a recess 6 for receiving a needle package 7, while the part 2' is provided withaloose plate 8 behind which springs Qare disposed pressing the loose'plate 8 forwardly against the side of the needle package.

The plate 8 is, however, prevented from leaving the part 2 by screws lO passing loosely through holes 1 The face of the plate 8 is slotted longitudinally at two positions as shown at 12.

f Slidably mounted in the part 1 is a pusher 13 having a pair of spaced fingers 14 which extend throughslots in the part 1 and enter the slots 12 in the plate 8.

These fingers 14 engage behind the row of needles 15.y

The pusher is connected by a flexible member 16 to a rotatable drum 17 within which is mounted a flat coiled spring 18 of the clock spring type. The drum l17 is rotatably 6 6 of rigmounted upon a pin 19 attached to the vpart Y 1. The arrangement is such that the spring 18 places a tension on the flexible member 16 and tends to draw the pusher 13 towards the right hand end as seen in Figure 6. The

flexible member 16 is taken over a guide pin l or roller 2O asshownin Figure 5.y

Thepusher13 yis furthi' provided with a finger piece 21'attached to the pusher by aV stem 22 passingthrougha slot in the plate 4, the purpose ofthe finger piec'e 21-b'ein'gy toenable the pusher to be withdrawn when the magazine has been emptied to enable lfresh needle package Atofrbe, inserted,

The needle package may be similar toi-that described in inyfspeciiicatio'n No. 31,1040 of 1,928, and may include a sheet metal Vclip 24 containing` the row ofneedles 15 retained between the lugs Qfandv 26, the clip Q4 r:also having holes 27. f v

When this needlepa-'ckageis to be placed in the magazinet-he holes 9a7-fare inade to -engage'l {with pins 28 Vin the magazine, the needle package being positioned thereby, and

the part 1 of thefmagazine is further provided with a projection 29 which passes be- `tween-the lugs 26 of the needle'package and 37 'on the .part 2.?

engages the end needle ofthe row so asV to form 'a guide for'said needle while it lisbeing ejected.

lt 'will be lunderstood that the ingie'rs 14 extend through the slot 30 in the'ba'ck of the clip 24. Y Y c e Y As each needle is ejectedy from the magavzineby means hereinafter described,the row `of needles V is fed'forward by the pusher 13 by a distance equal to thegdi-ameter of one needle, and Y during such feeding movements k the row Yof needles is guided between Vribs 31 on the

Aplate

8 and 32 on the part, 1, these ribs preventing the .needles from :over-riding 'each other. v l

f The two-,

halves

1,2,of the magazine proper arelockedtogether bymeans of a small 'eye e V,bolt 33 pivoteda't 34 to a-lug 35 on the .part 1 and by la nut `36km thefeye fbolt engaging lugs The base meinberer carrier'is shown at'38 fand it is'recessed at 39 for-receiving the base "s provided adapted to vvact upon either 'of two

Y plates

43, 44, associated with the lbosslofthe 'n lever 41to' retain the lever either inthe' position shown inFig'ure 3 for in areleasedp'osition.

Near one end the-part ylis provided with a Y sliding pin under which is a spring `46, the

sliding pin having a head 47 tof which is at- 'tachedy a plunger 48- for ei'ecting 'the :end needle of the'row.

. n will besten aat uit head 47 islam/idea rsfiaoso with'an inclined face 49 and the h-ead 47 is adapted to be engaged by a spring 50 connected to an operating plunger 51 which may be mounted on the gramophone and operated by any suitable means. l

Normally the plunger 51 reciprocates'the spring 50 so as to reciprocate the pin 45 and the plunger 48, but the mechanical 'connection between the plunger 51 and the head 47 which isv formed by the springO can'be severed bythe 'e'r'ank arm 5'2 "on' the lever 41, the arrangement being such that when the lever 41 is moved yinto its releasedr position, the

crank arni-52 is .turned so `ras vto .pull the spring 50 away from the head 47. A

Thus the act of releasing the magazine from' its

base

3,8 also-automatically releases the spring 5'0 from-the head 47 so .that the magazine can `becreinoved from its base 38, the spring'46V `ca'usin'gthe pin .45;to rise and carry with it the yplunger 48 thus freeing the plu-nger from the`v needle package l24 and enabling the latter' to be removed if required.

When the magazine yhas kbeen recharged `and is replaced in its base, the springj50 will automatically re-'engage thefhead 47 by rea- 'son ofthe fact thatthe hooked end 53 of the spring`50 will ride over the incli-ne49 and engage on the upper surface of the head 47 Thefneedlepackage 24 is provided with ar hole 54 opposite the' end needle 'of the row, i. je. the first needle .tobe ejected, and asimilarhole is provided in the lower edge ofthe needle package.'V

1n order to preventthe end needle ofthe.

row from dropping out, I may provide a removable coveiiitting over that fend lofthe -needle'paeka-ge wherethe hole 54 isplaced. The needlepacka'ge may bey placed in the magazine with this cover in position and one end ofthe recess 'vmaybeenlargedto provide vroom for the'cover which'is withdrawn VAas soon as 'the' needle package is 5in position in the ina'gazine.I f Y .'ln order tri-facilitate the loadingof la new needle package intovthe magazine, a'spring actuated catch 56 may be provided, 'the catch fbeingfpivoted 'atv 57 V(see Figures 1 and 2) tand having a finger piece 58 vby which it may be released after. the fresh need-le package :has been inserted and the magazine closed.

v'lhe'fcatch 56 may be actedup'onby a spring 59itending :to retain itin the position shown FigureV 1 and a stop may be provided to 'prevent it moving-beyond this position.

lThe finger piece 21 may :be shaped so :that when it is pulled back it will `smtoniatically push aside thecateh 56. e

Instead `of releasing the finger piece 21 'by hand afterthe magazine hasrclosed, l may provide means whereby it Yis Vautomat-ically released bynieans associatedwith the clip v41.
