To all whom 525 may concern.'

Be it known that l, JOHN HARRY CLEM- i'rnizcr, a citizen ot the 'United States, residing at Philadelphia, in the county` of 'Philadelphia and State of Pennsylvania, have invented new and useful lmprovements in Motordievvinding Devices for Talking- Machines, of which Athe following` is a specilication.

rlhe invention 'relates to music and more i particularly to talking machines, and phonograpbs,i and has for au object to providea machine in which the mechanism and sounding horn are contained in a suitable casing or box normally closed by alid which, whenl actuated, will Wind up the usual spring .motor for use in imparting rotation to the .record to produce the desired sounds and music.

' rlhe invention contemplates, among other features, the provision of a closure for' the box-like `body of the machine and which can'be automatically opened, said closure vwhen returned to closed position being adapted to Wind up the'motor which operates the record.

To vthis enclthe invention contemplates suitable mechanism having connection With the spring motor and the cover whereby When the cover is closed the spring, motor will be Wound up, said mechanism also including suitable means whereby the cover will be swung` into an open position when the same is released from its normal closed position on the box-like body or casing.

ln the further disclosure oi the invention reterence is to be had to the accompanying drawings, constituting a part oi this speciication, in which similar characters of reference denote corresponding parts in all the views, and in ivhich Figure l is a fragmentary' side elevationof e. talking machine lwith a portion of the side broken away to disclose the underlying structure Fig. f2 is a plan View, the cover having been broken-away; Fig.` 3 isa vertical sectional view 'taken on the line 3 3 looking in the direction. of the arrow; Fig. l

is avertical 'transverse sectional view taken on the line --ll in. Fig. 2; Fig. 5 is a vertical longitudinal sectional view taken on the line 5v5 in Fig. 2; Fig. 6 is a vertical sectional view taken `on the line 6-6 in Fig. 2; liig. .7 is a vertical sectional viewv taken on the line TM?. in Fig. Qyshowing in section the member for swinging the cover on the bon l0.

into open position; and Fig. 8 is a vertical sectional view taken on the line 8 8 in Fig. 2, showing the locking catch.

Referring more particularly to 'the views, l provide a box 10 in which is arranged the usual spring` motor 1l operating in co'm'unction with av vertical rod l2 supporting; the usual record tablet 13 and over which 0perates the usual reproducer I-l carried-on the tone arm l5, said reproducer carrying' the usual' needle or sapphire (not shown). The box l0 is normally closed by aI cover lo and Which is preferably mounted to swing at the rear of the box and on its upper edge. The cover is normally held in closed position by a suitable spiing-actliatecl locking catch 17 which, gripping a. linger 18 on the cover, holds the same in closed position so that upon actuating the catch the cover Will he in unlocked position due to the engagement of the linger 18 with. the catch 17.

halounted to swing on thev cover lo are 'a plurality of side arms 19 having their lower endsy pivoted to similar arms 20 rigidly secured upon a horizontal shaft 2 journaled '29 and in the recess of the face is arranged a friction dislr which bears against a substantiallycircular plate 31 on the shaft 28. The other face of the toothed Wheel 27" has a friction disk 32 bearing against the saine and abutting against the friction disk is a holding member 33 in the nature of a. circular plate 3l and a tubular sleeve 35, said tubular sleeve loosely encircling the shaft 28 with a pin 3G passing diamotrically throughl the sleeve 35 and through a slot 3?' inthe shaft 28. A portion of the shaft 28 is threaded as indicated by the numeral 3B and arranged thereon is an adjusting member 39 in the nature of a nut and which member bears against one end of an enpansible spring i() encircling the shaft 28 and been ing' against the plate' lol", the member 33 lso-hold the plate in rictional contact with the disk 32 and also hold tue toothed Wheell A Weighted pawl 22 is car? ict 1 of the spring motor 11.

Win

.2S will result in rotation of the shaft 415 of the spring motor 11.

It will be apparent that when the cover 16 is in raised position on the box and the same is swung downwardly into a closed position the pawl 22, suitably weighted, will engage the teeth on the wheel 23, thus imparting rotation thereto and by having the wheel 23 meshing with the toothed wheel 24 on the shaft 25 and which, in turn, carries the toothed wheel 26 ,meshing with the wheel 27 onthe shaft 28, it will be apparent that r'otation will be imparted to the shaft-28 and by providing the coupling betwedn the shaft 28 and the shaft of the spring motor the result of the closing of the cover will be to rotatethe shaft of the spring motor and' wind up the spring motor so that the spring motor will, in turn, upon unwinding, rotate the shaft or rod 12 and impart rotation to the record tablet 13. When the lid is swung into an open position the pawl 22 will pass freely over the toothed wheel 23 so as not to impart rotation thereto and when the lid or cover is again closed the pawl positively engaging the teeth on the wheel 23 will again rotate the same to repeat the mentioned operation.

As mentioned heretofore, the ycover is nor mally held in closed position by a locking catch 17. In order to cause the cover to automatically open when the locking catch is actuated a weight arm 47 is rigidly carried on the shaft 21 and at its free end carries a suitable weight 118. This weight is of such a nature, size and heaviness that when the cover is released from locked position with the catch it will swing upwardly into an open position. It will be seen that the arms 19 are in the nature of rocker arms, the shaft being also in the nature of a rocker shaft and not capable of a complete revolution but simply of a backward and forward turning movement.

It will be readily apparent that if the cover is repeatedly actuated a direct connection between the cover and spring motor would result in the spring being wound up too tightly and in order to. obvia-te this discrepancy the friction dis is and'32 are provided and arranged as mentioned heretos' l v 1 fore, so that if the cover-is repeatedly actir ated the spring motor on being wound to its limit will not be wound up any farther in view of the fact that the connection between the toothed wheel 27 and the shaft 28 is one of friction, the spring 4:0 being so adjusted as to provide sutlicient frictional Contact between the toothed wheel, the disk and the shaft that a rotation of the toothed wheel with no rotation of the shaft 28 will only occur when the spring motor has been wound to its limit. i From the foregoing description it will be readily seen that by simply actuating the .spring catch 17 the cover will be released to automatically spring into an open position and upon the subsequent return of the cover to closed position the spring motor will be wound up 'in order that it will impart rotation to the record tablet in the manner set forth. The box 10 is preferably built or constructed with the usual horn or other sounding member (not shown) inside, although it will be understood that the particular mechanism described can be used in connection with various kinds of talking machines or phonographs, and that the relation established between the weighted member on the shaft 21 and the mechanism heretofore described and which connects with the spring motor will result in providing a box having a cover that can be automatically opened and which, when closed, will wind up the spring motor of the talking machine.

Having thus described my invention, I claim:

1. In a talking machine, the combination with a box, of a cover therefor, a motor in the box, a shaft journaled in the box, a connection between the shaft and the cover, driving mechanism connecting the said shaft motor whereby when the said with the said cover is closed on the box the said motor will be wound up, and gravitating means on the shaft for swinging the cover from a closed to an open position.
