Patented Dec. 30, 1924.



Application filed April 30, 1923. Serial No. 635,729.

To all whom 62- may concern:

Be it known that I, JOSEPH M. SUARnz, a subject of the King of Spain, residing at 1810 Gough St., in the city of Baltimore and State of Maryland, have invented certain new and .useful Improvements in Adjustable Supports and Lifters for Covers, of which the following is'a specification.

This invention relates to closure fasteners, and more specifically, to an improved adjustable support and lifter for covers. It is particularly adapted to and useful for adjusting covers or domes of talking machines in the partly open or wide open positions, but is also useful for covers of pianos and other articles.

One object of this invention is to provide for very quickly and easil adjusting the cover upwards or downwar s, backwards or forwards, and preventing the cover from falling from its raised position. Another object is to provide an automatically looking or frictional detaining device which is very convenient to the hand of the operator who is in position to place or remove the records of the talking machine, this detaining device being of comparatively simple and easily manufactured construction, also very quickly and easily operable for releasing the link which connects it to the cover or dome.

Other objects and advantages will be pointed out or implied in the following details of description, in connection with the accompanying drawings in which,-

Fig. 1 is a side view of a part of a talking machine cabinet to which this invention is applied, part of the device being in vertical section, and a part being shown in mechanical detail atthe upper right corner. Fig. 2

is a sectional view in the plane of line 2-2 of 1. Fig. 3 is a mechanical detail showing one of the parts in three positions. Fig. 4 is a view of a. fragmental part of the spring-hinge which I may employ to raise or assist in raising the cover to its difierent adjusted positions. Fig. 5 is a section in Similar reference characters in the specification refer to similar parts throughout the several views of the drawings on which such reference characters are applied; and A refers to the body or casin of a talking machine of ordinary form or 'nd, while B refers to the cover or dome theref. The hinge 10 may be of the form shown in Figs.

- with this slot.

4 and 5 or of any preferred and permissible kind. In this hinge, the complemental halves are slotted to receive springs 11 whose ends are beveled, as shown in Fig. 5, to fit the beveled ends of the slots 12, one of which slots is shown empty at the right side of Fig. 4. The middle part of each spring 11 is coiled around the pintle-13 of the hinge, and its beveled ends co-act with the pintle for holding it in its operative position. The hinge preferably extends substantially from side to side of the casing A, and the series of springs 11 extends substantially from end to end of the hinge, so that there may be any appropriate number of these springs,

according to the length of the hinge and the v lifting strength required therefor.

The left wall of the casing A is here shown apertured at 13 to receive .an apertured plate 14 which is formed intergrally with a flange or plate,15, the latter. being provided with screw-holes 16 and a slot or opening 17. The aperture 13 is longer and wider than the plate 14, thus providing space by the latter for receiving a link which is preferably arcuate and provided with an arcuate slot 19 which extends approximately from end to end of the link, the arc of this slot being approximately so that it permits the cover to be swung upward, backward and slightly downward, as will presently be shown. The upper end of this link 18 is pivoted at 20 to a pair of spaced apertured ears or plates 21 which are preferably formed integrally with a. plate 22, the latter being provided with a slot or opening 23 through which the link 19 extends into the opening or space between the cars 21. The

plate 22 is also provided With screw-holes through which screws extend into the cover B for securing the member 21-22 in place.

The cover is recessed to receive the member 21-22 as shown in Fig. 1.

Screws extend through the screw-holes 16 into the casing A, for holding the member 1415 in place with its opening or hole 24 at the slot 19 and in open communication A bore or housing 25 is formed in the casing A and communicates with the hole 24 through the intervening slot 19. The outer end of this housing is closed by an apertured plate 26 and aplunger 27,. the latter extending through the aperture of the plate 26 and havinga reduced inner end which extends through the slot 19 and fits in the hole 24. A nut or collar 28 is around the plunger 27 and is compressed belower-end of the slot 19 from movingup besaid cover to sai tween the plate 26 and the nut or collar 28 so as to normally ress the nut or collar tightly against the link 18 and thereby exert sufiicient force and cause sufficient friction to efficiently co-operate with the spring-hinge in holding the cover in any of its adjusted positions. -The plunger co-operates with both plates 14 and 26 for preventing the yond a predetermined limit, thus limitin the rearward movement of the cover B, an

.the curvature of the link 18 permits it to ield suificiently to act as a shock absorber 1n case the cover tends to move beyond its limit. This link is preferably of hard brass, bronze, plated steel or other suitable springy metal or other material.

The device is operated by means of aknob or handle 30, and by pulling this handle outward, the spring 27 is compressed and the nut or collar 28 is moved out of contact with the link 18, thus relieving the frictional contact of the members 18 and 28, and the right hand of the operator may now be uSed to assist the spring-hinge in raising the cover, or may lower the cover against the slight resistance of the spring-hinge, while the left hand holds the plunger-handle 30.

It is not intended to limit this invention to the exact construction and arrangement here shown, but changes may be made within the scope of the inventive ideas as implied and claimed.

What I claim as my invention is z--- 1. The combination of a body, a cover therefor a sprin hinge uniting one edge of 5 body and constantly tending to raise the cover, a link secured to said cover at wdistance from said spring-hinge, said body havln an aperture therein to re- Y I ceive the link w on the cover is down, and

body having a housing therein, a plunger provided with a handle and a frictional detaining element, the latter being in said housing, said plunger extending through said slot and hole, and means including a spring in said housin for pressing said frictional detaining e ement against said link so as to co-operate with said plate for holding said cover at different adjustments, said handle being'operable to withdraw said detaining element from said link.

3. The structure defined by claim 2, saidplate having a slotted plate united with its upper end, said slotted plate being at right angles to the first said plate and provided with means for securing it to the upper surface of said body, the slot of said slotted plate being or" a length and width corresponding to the cross section of said link said link extending through said slot and guided thereby in its upward and downward movements.

4'. The structure defined by claim 2, said link being arcuate and of springy material, for the purpose specified.

5. The combination of a bod including a wall, a cover for said body, a inge uniting the cover with the body, said wall being provided With an aperture which opens through the top of the wall, also provided with a housing which communicates with said aperture and opens through the outer side of the wall, a link secured to said cover and extending down into said aperture, a plate secured to said wall and having an opening therethrough which communicates with the interior of said housing, a plunger extending through said plate into said housing and normally in frictional engagement with said link, and a spring in said housing and cooperative with said plate for yieldingly maintaining said frictional engagement.

(3. The structure detinedby claim 5, said link bein formed with a longitudinally extending s ot, a member including a horizontal plate and a vertical plate, the latter being in said aperture and having a hole therein, said'plunger extending through said slot of the link and through said hole, said horizontal plate lying fiat on the top of said wall and secured thereto.

In testimony whereof I afiix my signature.
