PHONGGRAPH-Lifl) SUP-PORT.

Application filed May '6, 1922.

1 To all who-m it may concern.

Be it known that I, livimnnmi Ann-nun, a citizen of the United States, residing at Rockford, in the'county of Winnebago and State of Illinois, have invented a new and useful Phonograph-Lid Support, of which the following is a specification.

This invention relates to a support for phonograph lids adapted etiectively to prevent the lid from dropping andlalso :to in.- sure the proper'counterbalancing of the lid so that it may be left at will in either open, intermediate or closed position.

Que off the principal objects of the invention is to provide a support of exceedingly compact form which is arranged to be mounted above the motorboard at the hingeconnection between the lid and the cabinet, thereby obviating the necessity for making holes in the motorboard which besides theing'unsightly are objectionable in that dust and dirt and frequently reproducer needles fall through them and lodge in the driving mechanism suspended. under the motorboard. The manner of attachment, further-- more, enables individual users to procure the support as an .accessory and to apply the same to replace the ordinary prop type of supports with which, phonographs hare conn-nonly been equipped in the past.

Another advantage arising from the. manner of attachment of the support is that it can be positioned in the middle of the lid or nearly so and is not limited to attach "ment at the sides are prior supports.

Varping of the lid is in this way avoided although only a single support is used instead of having to use two supports, one at each side. as some manufactures have done in an effort to prevent warping of the lid. Furthermore, the support being above the motorboard is readily accessible for the purpose oi adjustment.

A further object is to provide a lid support which by virtue of its compactness can be applied to either the dome or theconsole type of phonograph of practically all standard makes.

A still further object is to provide a sup port of attractive appearance which is simple and economical to manufacture.

In. the accompanying drawings illustrating a preferred embodiment of my invention Figure 1 is a vertical section through Serial No. 558,847.

the upper rear portion of a phonograph of the dome type, showing a lid support constructed in accordance with my invention operatively connected between the cabinet and the lid thereof, the lid being illustrated in open position. Fig. 2 is a similar view showing the lid support in section, the phonograph lid having been moved to closed position. detail of a portion of the lid support and is taken on the line of 2. Fig. 4i is a view similar to Fig; 1 showing the support applied to a phonograph of: :the console type. Fig. 5 isa sectional :detail on a reduced scale of a phonograph cabinet illustrating how, in accordance with my invention, single lid support may be attached at the middle of the lid to support the same without causing it to warp.

\Vhile I have herein shown my invention. as applied to .phonographs it will,.of course, he understood that the same may be adapted to use with various types of cases and cabinets wherein counterbalancing lid supports find use, and although the invention is hereina-fter described with considerable particularity, it is to be understood that the invention is not limited thereby in the interpretation of the apipended claims except as necessarily limited by the state of'the prior art.

Referring to Figs. 1 :to 3, inclusive, the reference numeral 5 is applied to the support as a whole mounted in operative relation to .alid '6 hinged at 7 to the phonograph cabinet 8. The phonograph illustrated 'i Figs. 1 and 2 willbe recognized as being of the dome type wherein the motorboard 9 oc-' cupies position close to the top of the cabinet, thus providing on lya shallow upper compartment 10 wherein the turntable is mounted .to operate. In this type the lid 6 is hollow and has inclining ornamental side walls 11. When used in connection with this type of phonograph the support is mounted substantially as illustrated in Figs. 1 and 2 with the

brackets

12 and 13 thereof secured respectively adjacent the upperedge' Fi 3 is a transverse sectionalsupporting arms 1% and and an auxiliary or

secondary pair

16 and 17. The arms 1% and 15 are preferably channel-shaped in cross section as most clearly appears in Fig. 3, the arm 14 having its side walls fitting within and pivotally connected to the side walls of the arm 15 by rivet pins 18. The free ends of the arms 14. and 15 have their web portions bent to provide eyes pivotally connected to the

brackets

12 and 13 by pivot pins 19. The pins 19 preferably have their ends upset similarly to the pins 18. The

arms

16 and 17 form a toggle connected between the arms. 14 and 15 as shown. The arm 16 of the toggle is preferably channelshaped in cross section. The arm 17 of the toggle preferably comprises a pair of links pivotally connected to the arm 16 by means of rivet pins 20. The links comprising the arm 17 ar similarly pivotally connected to the arm 15 in its opposite side walls by means of rivet pins 21, at a point intermediate the ends of the arm 15. In a similar manner the arm 16 is pivotally connected to the arm 14 by rivet pins 22 at a point inter mediate the ends of the arm 14.

The

arms

14, 15, 16 and 17, it will thus appear constitute a quadrilateral frame, two diagonally opposite corners of which are connected to'the cabinet and to the lid, respectively, so that in the swinging movements of the lid from open to closed position the frame is distorted for a purpose presently to appear. The other diagonally opposite corners of the frame are joined by a coiled tension spring 23, the one end of which is bent to provide a hook 24 entered through a slot 25 in the web of the arm 16 and arranged when in operative position to fit in a notch 26 in the outer edge of the web of the arm 16 thus to prevent the spring from turning. An adjustment of the tension thereof may be made by a screw 2'T entered through an opening 28 provided in the extended web of the arm 1% (see Fig. 2). The screw 27 threads into a nut 29 upon which are suitably clinched the convolutions of the reduced end 3 of the spring 22'. it will be noted that in operation the head of the screw 27 is presented at the front side of the support where it is readily accessible for the purpose of adjustment. Thus when a screw driver is engaged therewith to turn the same, the nut 29 being of course prevented from rotation within the end of the spring 23, the tension of the latter may be adjusted as desired. Thus the user will, after installing the support, determine from experiment whether the tension of the spring is sufficient to counterbalance the lid in its various operating positions, the spring being adjusted correspondingly as the lid is heavy or light.

A stop for limiting the extent of swinging movement of the lid is preferably provided to avoid possible injury in the careless handling thereof. I prefer to provide in this

connection shoulders

30 and 31 on the arms 1 1 and 15, respectively, provided by the ends of the webs of the two arms. Thus, when the arms arrive at the relative positions shown in Fig. 1, the shoulders come into abutment and prevent further relative pivotal movement thereof and thus limit the extent of movement of the lid.

In the operation of. the device it will be apparent that when the lid is in its extreme open position as shown in Fig. 1, a con siderable portion of the weight thereof is supported directly by the hinges 7, that is, comparatively little counter-balancing effort is required to sustain the lid against dropping. Accordingly, in this position of the lid, the spring 23 is adjusted to comparatively light tension. However, as the lid is moved toward closed position the tension of the spring must necessarily become progressively greater to provide greater counterbalancing effort for obvious reasons. In fact the counter-balancing of the support with a proper adjustment of the spring tension may be made suliicient to prevent the lid from dropping excepting perhaps only gently. l Vith a proper spring adjustment the lid may be counterbalanced so that it can remain at an intermediate position unless actually moved to closed position. At the extreme closed position the spring tension is considerably greater because of the distortion of the support frame wherein the diagonally opposite corners thereof are considerably displaced as will be apparent by comparison of Figs. 1 and 2. By virtue of this counterbalancing action of the support and the preciseness with which it may be adjusted, the lid may be made to operate with considerable ease and in fact it should require practically no greater effort to raise the lid from an extreme closed position than from an intern'icdiate position to open position if proper adjustment has been made. It will further be seen that by the particular mode of attachment of the support the diagonally opposite corners of the frame are disposed normally approximately in horizontal alinement. Then as the lid is closed the diagonally opposite corners are displaced in the distortion of the support frame. The elongation of the support frame by distortion can be effected in a relatively confined space as will be noted from Fig. The support is, of course, attached so as to avoid interference with the turn table and when in use does not constitute an obstruction as do the ordinary prop types of supports. I

It is furthermore possible with this lid support to attach the same at the middle of the lid or nearly so as appears in Fig. lVith this arrangement warping of the lid is effectively prevented although only one support is used. Obviouslv the support may be attached alike to either the console or dome. types of machines so that a single standard size serves for both styles of instruments. This obviates the necessity for providing arms of different lengths for the two styles of machines as has been the practice in the past. It is further apparent that since the device may be attached to the underside of the roof of the lid and at any point on the lid without regard .to whether it is the right or left hand side, the necessity for providing right and left hand fittings, as was commonly necessary where the supports were limited to attachment at the sides of the lid, is of course also obviated.

In Fig. 4: I have shown the device as ap plied to a phonograph of the console type. In such phonographs the lid :6 is usually flat and the motorboard 9- considerably sunk in the cabinet to provide a relatively deep upper compartment 10". When used with this type of phonograph the one bracket 12 will be secured at a point somewhat below the upper edge of the inner rear wall of the cabinet compartment 10, the other bracket 13 being secured to the underside of the lid 6, similarly as in the dome type of phonograph.
