Application filed' December 17, 1920. s wn in. unset.

To all whom it may oomem I Be it known that I, Fiuzniuuoit LUItEKZnK, of the city of Chicago, Cool: County, Illinois, have invented kl; certain new and useful Improvement in Combination Tahies and Pholio rephs, of which the following is n specific tion,

' This invention relates to tall-ring machines and phonographs in general, but more purtic'ular'ly to'those which have a rotary turntable for -disk records, and which have a reproducer which floats on the record during theoperation of the machine.

Qno object of the invention is to proi'i'de an im )roved constructionnml arrangement where ythe phonograph or talking machine is movable into a storage position in astructure of any suitable character, such s a. table, when the machine is notin use, and so that the structure may be used for some other urpose.

- To ese'and other useful ends, the invention consists'in matters hereinafter set forth and-claimed, and shown in the accompanyimi drawings, in which:

igure 1 1s e'plan of a table phonograph ortalkinig' machine embodying the principles of the invention.

, Figure 2 is a front elevation of said table. Figure 3 is a view similar to Figure 1, SllOWlIlfL the closure open to bring, the phonograph into view inrthe well provided for this purpose in the'center of the table.

Figure 4 is a ,front elevation of said table and phonograph, as shown in Figure 3, showing the turntable and repmducer in raised position. i t

Figure 5 is a longitudinal section on line 5- 5 in Figure 7. V

Fig. 6, is at similar view showing the phonograph in operative position.

v Figure 7 is an enlarged plan of the structure with the table top removed and with certain parts shown in horizontal section.

F' ure 8 is a transverse section on line 8-8 111 Figure 7. A

.Figure 9 is an end elevation of the table.

Fi 'ure 10 is a detail sectional vien showini; the movable throat in raised position to deliver the sound vibrations to the resonator.

v Figurell is a similar view showing sai throatin the lowered position which it occupies When-the phonograph is stored in the table.

Figur 12 is a detail View of a 150k for the support iupon which't hel reproducer and its tone arm and the throat are mounted. F gure 13 is a sectional View of said lock. Figure 14 is a detail sectional view of the friction devicewherehy the closure and modifier jo'rjthe outer end o the resonator are held in different jositions. As time illustrat the invention, comprises a-tabie top 1 prcvided'with sides 2 and ends-3 and 4, together with legs 5 of any suitablecharacter, The saidtable is constructed with a well .at its center, forming a chamber 6 having shorten? and a closure 8 at the top thereof. This closure 8 is preferably rectangular in form, and is shaped to fit the upper .end of said well'or chamber 6, lieing provided with hinges 9st one end thereof,

of any suitable character, so that the closure can he swung over flatwise upon the table, as shown in Fi 'ure h, or swung hack to closed position as shown in Figure 1 when it is desired to use the structure as an ordinary table. Said closure ispreferably provided at its free edge, on its under side, with a metal strip 10 having openings therein for the dowel pins 11, and having other openings to engage the ends of the hooks or catches 12 by. whichthe closure is retained in its closed position flush with the top surface of the table. S aid'dowel pins 11 are movable up and down intlie structure, and in a stationary transverse guide 13,, being held in raised positionby the springs 14 suitably applied thereto, whereby these springs are compressed by the downward movement of the pins 11, which latter are in the form of rods. Thus. when-the closure is unlatched or'imlocked thepins or rods 11 more upward slightlmthusgifing the closure a slight iriitialopening movement so that the hand can he insertedumderthe edge of the closure to pull it upward snd over into its open position ,flatwlse upon the table top. Thehooks 12 are pivoted at 15 at the lower ends, on the structure of the table, and face in the same direction, or toward the some side of the table, and are connected together by t, rod 16 which slides in the guide 17, a

compression spring 18 being interposed between-this=g ide and one ofthehooks, and

a compression spring 19 being inter osed between the other hook and the gui e 20, whereby endwise movement of said. rod to pull the hooksout of engagement with the closure serves to compress-said s rings, and

the latter serve to yieldingly' hold the hooks in locln'ng engagement with the closure.

To operate said rod 16 a bent lever 21 is arranged to operate back and forth in the slot 2 in the wall 23 of the well or chamber in thecenter of the table said lever being pivoted upon the under si e of the table top at within the record chamber 25, and provided with a handle 26 for the Opera.- tion thereof. A hin ed closure 27 is provided for the record c amber '25, at the end of the table, of any suitable character. The other end of the table is provided with a stationary resonator 28 provided with an inlet end 29 at one side of the said well or chamber in the table, and provided at its mouth or outer end with a iolding modifier 30 which is hinged to the under side of the table top 31 and suitably connected atits lower edge to the closure 32 which is pivoted at 33 on the structureof the table. Said modifier 30 is preferably composed of two sections hinged together at, their edges, and each section is preferabl in the form of. a frame having a screen 0? cloth or other material thereon, as shown in Figure 9,'said modifier being entirely unfolded and disposed in avertical lune when the closure 32 is fully open, as s own in Figure 6; but when the closure 32 is swung upward, as shown in Fi ure 5, the modifier or screen 30 is then fdlde'd so that the two sections thereof lie flatwise together against the under side of the table top. The side portions of the said closure 32 are each provided with a series of small openings 34 disposed on the line of a circle struck from the pivot 33, and the table structureis provided with spring pressed locking devices 35 havino rounded ends to enter said openings, w ereb the closure 32 and the screen or modifier 30 may be held in various positions, depending upon the loudness of tone desired for themusic or the sound vibrations coming from the resonator. The closure 32 is provided with a handle 36 by which it can be forced upward or downwnrd, the devices 35 engaging the o ening 34 to hold the closure or modifier in different positions, as stated, and being so formed that they are forced back against the sprin when the handle 36 is forcibly move up or down whereby a sort of friction arrangement is provided for holding the closure or modifier or screen in different positions. as stated. It will be seen that the lower section of the modifier or screen 30 is rigid with the closure 32, but is hinged at its upper edge to the upper section of said modifier or screen, while the said up per section is hinged at 31 to the under side of the table top, as previously explained thus ermitting the folding operation shown and escribed. The structure thus far described is well adapted for use as a table, as

with the three closures 8, 27 and 34 in closed position there is nothing to indicate that the table contains anythm unusual, or is anything more than an ordinary table, such as those used for writing or library purposes.

The phonograph or talking machine which is normall concealed in the-well or chamber 6 )revious y mentioned may be of any suitab e known or approved character. As Shown, said talking machine comprises a horizontal support 37 mounted on brackets 38 and provi ed on the under side thereof with a motor 39 of any suitable character, and at its top with an ordinary rotor turntable 40 to receive the flat or disk-1i c records. The well or chamber 6 contains a transverse wall or support 41 upon which. are pivoted at each side of the chamber a pair of short arms 42 the other end of which latter are pivoted on the brackets 38 to form a parallel notch or connection or sup ort' ing means for the motor or turntable ith this arrangement the motor and turntable are movable up and down bodily, and the turntable is always level. A similar horizontal support 43 is provided for the reproducer 44: and its tone arm 45, which latter is removably coupled to the swivel 46 at the upper end of the throat 47, from which latter the sound vibrations are delivered to the previously mentioned resonator. When in raised position, as shown in Figure 6, said reproducer can be swung over to permit the needle or stylus thereof to enga e the record on the turntable in the usual and well-known manner. The reproducer is thus adapted to be swung from above the turntable, as shown in Figure 5, in order to permit closing of the closure 8 above the depressed phonograph in the well-like position in the table. The long arms 48 are pivoted on the support 41, and are also pivoted on the brackets 38. and at their extreme ends are pivoted on the brackets 49 which carry the support 43 for the reproducer and tone arm. Thus the support 43 has a greater range of movement than the support 37, so that the re roduccr and tone arm move up and down odily a greater distance than the turntable and its motor, but the two supports 37 and 3 are in the same horizontal plane, as shown in Figure 6, when the turntable and its motor and the reproduce]: and its tone arm are in their raised or operative positions and are ready for use. When the phonograph is in storage position in the table. the parts are then in the positions shown in Figure 5, it being observed that the support 43 is some distance below the support 37, necessarily. in order to bring the top of the tone arm 45 below the plane of the closure 8 when the latter is in closed position at the top of the well or chamber in which the phonograph is stored when not in use. A spring 50, of

shown in "Figures 12 and 13, isprovided on the support. 43 to engage. the socket formecl'm the table structure to hold the phonograph in raised position. When the phonograph is in its raised cooperative pos1- tion, the throat i7 is directli 1 opposite and preferably in 'engsgementwit the said resonatcr 28-, as shown in Figure 10, and. when the phonograph is lowered into the storage position said throat 47 then occupies the positionshow'n in Figure 11 at the bottom of the well or'chnmberfi in the center of the table.

The-'swivelefipermitsthe reproducer and its tone arm, of course, to lie-swung around in the usual rirwell-knownnmnner, and to "be removed when suchis necessary or desirehle, so that the throat 47 forms an intermediate separate element between. :the resonabo'rand the tone arm. When the closure 8 is ushed downward, it not only pushes the ro s or dowel pins 11 down, as previously explained but it also pushes the downward against the tension 0' the spring 50 whereby the raising of the 'closu-re '8 permits the spring 50 to raise the phonograph into operative position. When it is desired to store'the ho'nogmph, the lock 52 is releuseinnd 't e closiu'e 8 is then swung over :upon the phono raph, and the latter is pressed downwo hy the final closing movement of the closure and the latter 13 automatically latched by means of hooksor catches 12 previously described. The supports 37 and i3 can-not rise higher than the plane or level which they occupy in Figurefi, as the brackets 49 enguge the tedges'of the support 37, thus. locking the mechanism against further outward movement, innsmuch asthc support 43 moves Inward much faster than the su rt '37 an this movement is renderedl mpossibile, of course, as

soon as thebra-ck A9 engage the su port 37, as this preclhdcs any further re utive upward movement between the two supports.

From the foregoing it will be seen that the phonograph is movable bodily into an out-of-stomge position in the table. As shown and described, the movementof the turntable and its motor bodily is forthe purpose of storing the talking machine in the table and this is also the pur ose ofthe movement of the reproducer an tone arm bodily upand down, but it will be under stood that the novelty of the construction and mode of operation can be used for any suitable or desired purpose. The invention, therefore, is not limited to the exact conhonogrnph struction shown and described and the con struction and in'ode of operation are not limited itoanny particular purpose or use, the

strupture'shown fund described being illustretive of one purpose and useof'the novel construction and mode of operation illustretednnd-expluined. Also, as stated, the

phonograph may behf any suitable, known or approvedrchnracter, but for some reasons,

and for the purposeshoivn anddeseribed,

the phonograph is preferably so-nrran d that theturntahle arrid its niotorare more le up and down bodily, while the 'reprodncer and its tone arm :are movable in -a similar manner but'to a gr-enter extent.

Thecrauk so can be inserted through the 11011355 to windthe motorpin the ordinary manner, when the motor is in elevated position. Thus the motor cannot be wound when the phonograph or talking machine is concealed in then-table, as themeansitor cngngemen't with the crank 54 'iu'c notepposlte thehole' 55 exec when the motor is raised in the manner ascribed.

In combining ztphonogmph with :1, table,

it becomes important, of course, to retain the; essential requirements of a twbltc. The top of it table must heucertain distance from tl1e,floo1-,.-and, the clearance below the table;- must be of a: certain character, and of a certain height, otherwisethepiece of flllllihllTB, althou h resembling o table,

may not be adopted or use nssuch. With the construction .115 shown and described, therefore-one object is to keep. the bottom wall 7 of the storage chamber from com ing too low in the structure, so that it will not interfere with the use-of the piece of furniture e sa -reel. table. The top 1 is the required distance above the floor, and so is the bottom wall 7,-1vhe1eby the table can be used by at person seated inf-rout thereof intheusual. .or ordinarynmnner. If the turn-table were on the some support upon which the reproduoer is mounted, it would become necessary to lower the honogmph to a greater exteut in. the :to. e and the wall 7 would then-been lowthat it wouid interfere with use of the table in the desired manner. With the construction shown and described, the tum-table movesfidown the minimum-distance necessary to get it below th'e cover or closure '8, so that the latter isadnfted to overlie the flat horitop of the turntable 40, so that the latter is presented or held practically flatwise to the underside of said cover, with only slight space if any between, thus minimizing the depth of the store. e position of the talkinggmachine below t e table top.

xoept for the fact that a record might be left on the turntable, and that the latter usually has a center post to engage the hole in the'center of the record, no space is really necessary between the top of the turntable and the underside of the cover 8 of the'table top. Therefore, of course, but slight s ace if any is necessary for this pun pose. ut, in any event, the re reducer is not between the cover and turnta le when the machine is in the storage position thereof.

What I claim as my invention is:
