CHARLIE J. BOU'SFIELID, F BAY CITY, MICHIGAN, ASSIGNOR TO THE DELPHEON COMPANY, OF BAY CITY, MICHIGAN, A CORPORATION OF MICHIGAN.

HINGED-COVER SUPFORT.

Specification of Letters Patent.

Patented Apr. 9, 1918.

To all whom it may concern:

like.

Be it known that I, CHARLIE J. BOUSFIELD, a citizen of the United States of America, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Hinged-Cover Supports, of which the following is a specification.

T his invention relates to hinged cover sup. ports for talking machine cabinets and the Cale object of my inven ion is to provide means for holding the cover open through the instrumentality of suitable mechanism controlled by the tension or a spring.

Another object resides in the provision of means whereby the tension of the spring is exerted only when the cover is in open position.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form. size. proportion and minor details without departing from the spirit or sacrificing any of the advantages of the invention. V

In the drawings:

Figure l is a partial sectional side elevation of a talking machine cabinet equipped with my improved cover supporting means, showing the mechanism in two different positions.

Fig. 2 is an enlarged isometric view of the mechanism comprising the supporting means.

In the drawings. 1 indicates a talking machine cabinet, of the type now in general use. provided with the usual hinged cover 2 and motor board 3. A supporting member 4- is suspended from the motor board 3 which member carries the mechanism of the cover supporting means.

The cover supporting mechanism comprises a substantially vertical rod 5 pivoted at one end to the cover 2 by means of the bracket 6. The rod 5 extends downwardly into the cabinet through a small slot 7 in the motor board 3 and to the free end of said rod is pivoted one end of a bar 8 by means the pivot pin. 8 The opposite end the bar 8 is pivoted at 9 to one end of a lever 10 which lever 10 is pivoted intermediate its ends to the supporting member 4, as shown at 11. The lever 10 is oliset intermediate its length, as indicated by the numeral 12 to allow sufficient space for the member 8 to pass between the supporting member at and the member 10 when the cover is raised. To one end of this member 10 is secured one end of the spring 13, the opposite end of the spring being secured to screw member 1-iset in the motor board The atoreinen tioned pin 8 has an enlarged head at each. end thereof whi -h acts as a stop against the motor board 3 when the cover is raised, thereby limiting the stroke of the mechanism.

hen the cover is closed the mechanism assumes the position clearly shown in Fig. 2, in which position the spring 13 is under no tension whatever, and the weight of the cover itself tends to keep the same in closed position. W hen however, the cover is raised to the position as shown in Fig. 1, the mecha nism assumes the position shown in the dots ted lines. In this position the rod 5 is drawn out of the cabinet through the slot '2' until the enlarged heads of the pivot pin 8 engage the under side of the motor board and thereby limit the upward movement of the cover. By this movement the lever 10 is swung on its pivot 11 until the said lever 10 and bar 8 form a knee, as clearly shown in Fig. 2. This movement puts thespring 13 under tension, as shown, said tension being exerted agains the knee formed by the lever 10 and bar 8. It will thus be apparent that by reason of the spring 13 pulling upward on the free end of the lever 10, the tendency of the knee is to straighten out, and thus the rod is pushed upwardly and held in its extended position, thereby holding the cover in open position. v

From the foregoing, it will be apparent that I have produced a simple and easily assembled device capable of resiliently holding the cover in its open position. By means of the mechanism described, it will be obvious that the spring is put under tension only when the cover is open and thus the strength of the spring is not used when the cover is closed, thereby assuring Ionizer and more etlicient use of the spring. Furtherny r he that the-M1 moves in a substantially vertical plane, it is only necessary to provide a very small slot in the motor board 3, and therefore the use of the customary elongated slot in the motor board, which serves as an inlet for dust and dirt into the entrance of the cabinet, is obviated.

What I claim is 1. Means for supporting a hinged cover, comprising a member depending from the cover, a pivoted lever normally occupying a position about parallel with the cover when the latter is closed, a bar pivotally connected at its ends with the lower end of the depending member and lever, respectively, and a spring connected with the lever and sub- 1 jected to tension upon opening the cover and vre-acting through the changed relation of the lever, bar and depending member to press the latter upward and hold the cover open.

' 2. In a supporting device for a hinged cover, a rod pivoted to said cover, a pivoted lever, an intermediate bar having its opposite ends pivoted to the respective ends of the rod and lever and directed downward when the cover is closed, and a spring connected to said lever whereby when the cover is open said bar is directed upward and maintained in elevated position by means of the said spring to hold the cover open position.

3. In a supporting device for a hinged cover, a rod pivoted to'said cover, a pivoted lever, an intermediate bar pivoted to the opposite ends of the rod and lever, said lever and bar adapted to form a knee, and a spring secured to the lever and adapted to be put under tension when the cover is opened to'hold'said knee in extended position, wherebysaid rod is pushed upwardly to the limit of its traveltohold'said-coverin its open position. 7 i i 4. In a'supporting device for a hinged cover, a rod pivoted to said cover, a pivoted lever, an intermediate bar pivoted between the opposite ends of the rod and lever, said lever and bar adapted to form a knee, the lever being ofi'set intermediate its length, and a spring attached to said lever, said spring being put under tension when said cover is raised to hold knee in'extended Copies of this patent nlay be obtainedior position, to push said rod upwardly and hold said cover in its open position.

5. Means for supporting the hinged cover of a talking machine cabinet,'comprising a substantially horizontally disposed member pivoted to the cabinet, a second member depending from the cover and extending to a point below the horizontally arranged member when the cover is closed, a link connecting the lower end of the depending member with the contiguous end of the horizontal member, and a spring co-acting with the horizontal member and tensioned when the cover is opened to press the said depending member upward and, hold the cover in open 7 position.

6. Means for supporting the hinged cover ofa talking machire cabinet, comprising a substantially horizontally disposed member pivoted within the cabinet below the motor board, a second member depending from the member upward and hold the cover in open" position; 7

7. In a device of the character described,

a cabinet, a hinged cover for said cabinet, a motor board supported'in the cabinet and provided with a small slot, a supporting member suspended from said motor board, a rod connected to the cover and extending through the slot into the cabinet, a lever pivoted to the supporting member, an intermediate bar pivoted between said rod and lever, said bar and lever adapted to form a knee, and a spring connected to the lever and put under tension when said cover is raised to hold said knee in extended position, whereby said rod is pushed upwardly and the cover held in its open position.

In testimony whereof I affix my signature.
