AUTOMATIC NEEDLE-FEEDER FOR PHONOGRAPHS.

Specification of Letters Patent. Patented Apr. 29,1913.

Application filed May 14, 1912. Serial No. 697,177.

To all whom it may concern: I

Be it known that I, ELMER C. JORDAN, a citizen of the United States, and a resident of Sacramento, in the county of Sacramento and States of California, have invented a new and Improved Automatic Needle- Feeder for Phonographs, of which the fol lowing is a full, clear, and exact description.

This invention relates to attachments for phonographs on which removable needles are used, and among the objects aimed at is to provide a device of this character which will insure the least possible delay and trouble in making the renewals of the needles. It is quite usual in operating phonographs for the same needle to be used repeatedly when the best results can be received only when a fresh needle is used on each record. By the use of a device of this character there is little or no excuse for not renewing the needles according to highest demands. I

The invention consists in the novel details of construction hereinafter fully described and claimed and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the device attached to the tone arm of a standard phonograph, a portion of the magazine being broken away; Fig. 2 is a plan view of the same; Fig. 3 is a vertical section on the line 3-3 of Fig. 2, the parts being in normal position; Fig. 4; is a similar view on the line 4:-t of Fig. 2, the part-s being in position for receiving a needle into the chuck; Fig. 5

is a bottom plan view; and Fig. (3 is a fragmentary detailof the parts shown in Fig. 2, the toothed wheel being omitted.

As a suitable embodiment of this invention I have devised a bracket 10 of any suitable form or construction which is adapted to be secured rigidly, for example, by means of a clamp 11 upon the tone arm 12 of the instrument. Rigidly secured to the upper end of said'bracket is a magazine 13 Whichis shown as of a cylindrical form with a bottom horizontal flange l4 .and having an open top. In the center of the magazine is a stud 15 shown as carried by a cross bar 16, and on said stud is journaled a star or toothed wheel 1 7 between which'and the inner surface of the magazine wall are adapted to be carried a circular series'of needles 18 in spaced vertical relation. These needles are supported upon the afore said bottom flange lt of the magazine.

In order to deliver or feed, the needlssuccessively into the socket or chuck 19 of the reproducer 20 in a most expeditious manner, I provide a slide 21 whichis adapted to be of a portion of the reproducer, as for instance, the chuck aforesaid, being brought into-engagement with a lug 22 connected or slide is adapted to be maintained in its normal'positionby any suitable means such as a spring 24 connected to any suitable fixed part, as for instance, the bracket 10 said lug 22. The slide 21 guided in its reciprocations along the bottom of the magezine by a set of keepers 26, and 27, the latter of which embraces the slide above the lug 22, as shown. The front end of the slide 21 is provided with a slot 21, the outer end of which is parallel to the longitudinal axis of the slide and the rear end of which is offset to an extent substantially equal to the dis tance between the centers of two adjacent teeth of the wheel 17, or between the centers of two adjacent needles, such oiiset of the slot forming a cam shoulder- 28.

As indicated in Fig. at more especially, the bottom of the magazine is slotted at 29, which slot extends into or communicates with a slot 30 in the bottom ofthe flange 14 of the magazine and extending circumferentially therein to an extent substantially equal to the distance bet-ween two adjacent needles. In the normal position of the parts, a needle will be seated in the slot 30 and groove 21 and supported upon the keeper 27. When the reproducer is brought up to receive a fresh needle, the chuck 19 hearing against the lug 22 will cause the slide 21 to move from the position indicated in Fig. 3

to the position indicated in Fig. 4:, and durand having its other end bearing outwardly against the stud 25 connected to the afore-,

reciprocated rectilinearly across the bottom of the magazine in one direct-ion by contact secured to said slide as by a screw 23. The

ing such movement the cam 28 bearing against the needle then in the slot will cause a rotationof the toothed Wheel 17 and all of the needles carried by it, whereby the needle in the slot willbedrawn along the slot 30 and into alinement with the outer parallel portionof the slot21f. During this operaslide and adapted to be carried by it through. aslot 82 in the magazine and into operative engagement with the tz'i'othof the wheel in advance of the needle to be delivered. Any tendency of the toothed wheel to be retarded as by friction on its bearing stud 15 or the dragging incident to the large number of needles carried by it around the bottom flange 14, tending to hold the needle from dropping into the chuck, will be positively counteracted by the efiect of the pin 31 operating upon the toothed wheel, as above set forth. By this time the needle to be delivered will be free to drop from the magazine throu h the slots 30 and 21*, before described, an through the radial slot 27 in the keeper 27. The needle in the chuck may then be turned outward from the magazine through the slot 29 and be secured in /p'lace as usual.

{By the device in operation as.above set forth all of the needles in the magazine may be delivered successively to the chuck of the reproducer, the star wheel being operated step by step by the successive reciprocations of the slide 21.

- I desire not to be limited to the specific details of construction, reserving the right to modify the same with respect to relative sizes and proportions and to construct them of any suitable materials.

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

1. In a device of the character set-forth,

the combination of a cylindrical magazine having a slot in its bottom, a toothed wheel, journaled for rotation in the magazine and adapted to support a circular series of needles therein inspaced relation, the needles being adapted to be supported upon the bottom of the magazine, and means associated with the magazine for delivering the needles successivel therefrom, such means comprising a .s e movable rectilinearly across the bottom of the magazine and having a cam slot at one end cooperating with said slot in the bottom of the magazine, substantially as set forth.

2. In adevice of the character set forth, the combination of a cylindrical magazine having a bottom flange, a toothed wheel journaled therein on a vertical axis, said magazine having a slot in its bottom, a slide movable across the bottom of the magazine and having a cam slot cooperating with the magazine slot whereby a needle is brought into delivering position and the toothed wheel caused to rotate on its axis, and means carried by the slide to momentarily lock the toothed wheel from rotation, for the purpose set forth.
