rHoNoGRArH RECORD REPEATER.

Application lefl Gctober S, 1923. Serial No. 667,341.

This invention relates to phonograph record repeaters, and one object of the invention is to provide a repeater' which may be used on various makes of talkingmachines,

and in connection with disk records ot various sizes, and which will operate automatically 'to return the needle to starting position for the playing ot a record as many times as desired.

A further object of the invention is to provide a record repeater which is readily and conveniently adjustable for use in connection i with y a record of any given size between minimum and maximum. j

A stilly urtherobject ot `the invention is to provide a record repeater which is simple of construction, eitieient in operation, and adapted to be readily applied and adjusted for use, and' which may generally simulate 20 in appearance a serpent or scroll-shaped body of suitable design, thus serving'a's a novelty as well as an article ot utility of the character described.

y The invention consists ot' the features of construction, combination and arrangement of parts, rhereinafter fully described 'and claimed, reference being had to the accompanying drawing, in which :--y

Figure 1 is a plan view of a yphonograph record repeater" embodying 'my invention.`

. Figures 2, 3, e and 5 are, respectively, sections on the lines 2-2, 3;3, 4.--1 and of Figure 1. y

In carrying my invention into practice, I provide a phonograph record repeater which, in the form disclosed, comprises ytwo unitary late-like members 1 and 2, the member, 1V constituting the main part of the device and the member 2 an adjustable needleI guide, as hereinafter described. These members y1 and 2 may he made of sheet metal or other sheet material of requisite thickness, strength and durability, stamped or otherwise fashioned into shape and which may be made plain or unfinished, or finished or ornamented in any desired manner according to the taste or `fancy of the manufacturer or demand ot the purchasing public.l i

` The member 1 consists ot oppositely ex tending arms or portions 3 and 1, united at their adjacent ends by a U-shaped or arcu` ately curved oll'set portion' 5, and thence eX- ribs or rails 19 are arranged tending in reverse directions on desired lines ot curvature. The armB terminates at its free end in an inwardly bent or curved head 6, around the inner side `of which is provided an upstanding guide rib 7. Provided for cooperation with this rib is a stop rod Shav-` ing a beveled or tapered inner end 9 and provided at its opposite end with a knob or tlnger piece 10. This rod is adjustable to greater' or less degrees beyond the outer end ott the rail 7 in a guide sleeve 11 carried by the head 6 and is provided with a longitudinal groove 12 receiving a set screw 13 on the sleeve, whereby said rod is held from rotation and whereby it may be iXed in ad- Yjusted position, as will be readily understood.

The arm e* terminates at its free end in a disk or head let, arranged opposite the head 6, which head 11i is provided with an opening 15 tor the passage of the rotating turntable spndleof the phonograph machine. Provided on said head 14, in alinement with said opening 15, is a clutch heador terrule 16 slotted to provide a series of spring gripping iingers 17. These fingers are designed to lgrip the spindle `with sutcientiorce to couple the repeater for rotary movement with the turntable and record when the repeater is not positively held from movement, but have a light enough grip to slip upon the `spindle to prevent the repeater from rotating the turntable and record while the composition is being played andv during which time the reproducerneedle engages the ribs 7 orrod Sand holds the repeater from rotation.

Formed integrally with the arm t is asubstantiallyl/shaped or triangular web 18, the widened outer'edge portion ot' which intersects the arm 4 and the narrower or vertex end portion of which extends inwardly in proximity to the odset 5. This part 18 is provided with guide ribs orrails 19 forming the initial portion of a return groove or channeled guideway for the needle. These in close relation and approximately parallel at their inner ends along the narrow portion of the part `18, and rflare outwardly vand rearwardly to provide with the web portion 18 of the plate a -Haring entranceway 2O to 'said initialportion of the guide groove or guideway.` To

facilitatefth entrance of the needle into `said portion 20, the marginal edge of the .plate 18 is formedqwitlra .beveled "or inclined surface 21, up whichtlie needle'may easily ride. A brace 22 of suitable form-lyingfonthe, opposite side of part 18 from the forward portion of the arm 4 may iconnect the head 14 and outer end of arm 4 at a point opposite'tlieinner end oiferm 4. with the innerend of part' 18, thus mutually bracing andV rein` forcingsaid parts and forming an additional support'to` rest' upon the surfa'ceofthe record desirably increasingfthearea ofwthefdevi'ce as a Whole to preventthedevice fronrtilting and adapt the same to restl stably `uponthe record-When"inuseV The- -member'- i2 is arranged J to -liei ibetween the armsB and 41and isprovided ationeend Withian expanded disk-shaped portion or head-23? arranged i to underlie fthe rupwardly offset, 1sulrstantiallly hemispherical'iportion 24 of^a bracket.=plate 25 riveted or `otherwise suitably nsecuredito thewoffset 5, said fdisk or head f 23 being lpivota'lly connected with the part 24by a pin oririfvet126` The arm 2 isi suitably igroovedi and is. provided with spaced` guide railsl 271 `tu i formt a ychanneled guideway icon stituting ftheV .delivery portion of the return groove or :guidewayfrfor the needlegfsaid` delivery portion `and theainitiail portion; herein'betore `aeteired to, f being 1de signed to 'provide a spiral :channeled guide Way lofil suitable spiralrcontoun the-contour of which may .be varied` :byadjusting-A the member `2 on i its pivotal: connection 26.\ and in anarc iradiail'lywith:respect to the head 24 and 'turntable spindle andacenten of` the record-engagedtherewithl The rails27 are uniformly spacedto provide a eomparatively `narrow `guideway except atitheir inner ends Wherel theyare `slightly spread or flared g to provide an entrance'fportion 28,1deeigned Vto register; with the inner end ofthe initial portion of the guideway in any of therpositions' to which the imembe1m2 maimbewadjusted, ltori' the'icertain guiding Lof-t e lneedle from one 'portionuto the other of said guider Way.

andthe peripheral edge 23a ofthis portion ol' the disk 23 is thus arranged to frictionally engage/the wall 24a, providing coacting frictional lretaining surfaceson the bracket and .theidisk whereby the movable guideway arm 2 is'adapted to be held in any posii tion to `which it is adjusted Without the use of additional. or extraneous fastening mcans5 orthenecessity oi'adjustingany fastenifng means Whatever. y i

As stated., the device in practice may be made of sheet metal or other suitable material and it may be stamped up to provide stiffening ribs or bosses 3l at proper points to give it any desired strength and rigidity. For the purpose of preventing the device from scratching or otherwise marring the record, such device may be provided on its underside with a layer or Contact pieces 32 of felt or other suitable material. The device may also be made as plain or ornamental as desired, according to the taste or fancy of the userpand the demands of the purchasing public. lends itself to a formation which may simulate the general appearance of a coiled serpent, and it may be enameled or otherwise ornamented to delineate more fully the characteristic appearance of a serpent, thus adapting the device to serve as a novelty as well as an article of utility of the character described.

While the construction shown is preferred, it is to be understood that changes in construction, form, proportions and various details may be resorted to, within the scope of the appended claims, j without departing from the spirit or sacrificing any of the advantages of the invention. j
