UNITED STATES PATENT OFFICE.
FOREST CHENEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHENEY TALKING MACHINE CO., OF CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS.
LEVER-COUNTERBALANCE.
Application led November 26, 1919.
To all 107mm. it may concern.'
Be it known that l, Fem-1ST CHENEY. a citizen of the United States, residing at Chicago, in the county ot' Cook and State ot' Illinois, havel invented certain new and useul Improvements in Lever-Counterbalances, of which the following is a speciication.
lVhile applicable in principle to any sit.- uation Where movement of one body toward another is to be resiliently opposed, the embodiment herein selected :tor purposes ot illustration has been designed primarily for counterbalancing the hinging cover ot a cabinet, for example, the cabinet ot a talkingr machine.
`The invention has for its primary object to produce a simple and etlicient lever counterbalance that may readily be applied Within the limited space afforded by the inside Walls of the structure, with the end ot the counterbalancing lever connected through a link With the cover to be controlled; subordinate objects incident thereto relating to the provision of anchorage means that Will receive one end ot a helical spring While the other end of said spring is acting upon the inner end of the lever, also to render such anchoring means conveniently adjustable from the exterior of the mounting; and also to provide details ot construction that will be particularly advantageous in realizing these several objects aforesaid.
In carrying out the invention, according to the present illustrative embodiment, a combined housing, support. and t'ulcrum memberis provided, preferably in the form of a cylindrical shell, with a surrounding lia-nge through which to attach it, a controlling lever Working through a slot in the shell beingfulcrumed upon a stud carried Within the shell; an anchoring support being provided ivithin the shell in position to receive and sustain one end of a coiled spring While the other end is acting upon the lever the anchoring member being preferably secured by the ulcruming stud in a. manner to permit its adjustment about the latter and having an arm protruding beyond the shell through which to develop such adjustment for the purpose of regulating the tension ot the spring; and a novel construction of securing means being provided to hold the anchoring member to its adjustment.
The invention consists in the novel teatures of construction ot' certain of the parts Specification of Letters Patent.
Patented Aug. 16, 1921.
Serial No. 340,814.
above named, as Well as their organization or combination, hereinafter pointed out in the claims.
In the accompanying drawing- Flgnre l is a sectional view showing the application of a pair of lever counterbalances constructed in accordance with the present invention.
F ig. 9. is a section of the same in a plane at right angles to the section of Fig. l, and on an enlarged scale.
Fig. 3 is a detail View of a portion of Fig. 2 with the head of the casing removed to disclose the parts Within.
Fig. 4 is a sectional view taken in the plane of line 4 4 of Fig. 3.
Fig. 5 is a view of a portion of Fig. 2 showing the applica-tion thereto of a tool through Which adjusting movement may be imparted to the anchorage member ofv the spring.
4F ig. 6 is a detail view ot' the jaw ot the securing grip ofthe anchoring member; and
Fig. 7 is a detail of the tool shown in F ie. 5.
The device is intended tor resiliently supporting one member upon another, such, for instance, as the cover A over the well B ot' a talking machine cabinet, the device being designed particularly for application to the side Walls I) of such a cabinet.
l represents a cylindrical shell or casing having an attaching flange 2 and a closed head 3. F ulcrumed upon a stud 4 centrally located in the head 3 is the balancing lever 5 which Works through a slot 6 in the cylindrical Wall of the shell through an are which is sutlicient to t'ollow movements of the parts between the full line position and the dott-ed line position shown in Fig. 2.
Arranged Within the shell l concentrically with the stud 4 is a balancing coil spring 7, preferably of helical form, having its anchoring and controlling ends each at the circumference of the coil. These ends are provided ivith hooks 8 and 9 through Which they, respectively, engage the inner end 5EL ot' the balancing lever 5 and the end 10a of an anchoring member 10. The anchoring member is mounted upon the same stud 4 with the balancing lever 5, and it is adjustable concentrically with said lever or With the coil spring in order to regulate the tension of the spring. To impart this tensionregula-ting movement to the anchoring member 10, said member has an arm 10b protruding beyond the cylindrical wall of the shell through a slot therein, and said anchoring member is provided with a binding screw 11 through means of which it can be held to its adjustment. Screw 11 is iiXed against displacement in the head 3 of the shell where it is conveniently accessible to tighten it upon the anchoring member after the latter has received its adjustment; and to insure its control over the anchoring member itsinner end is threaded into a jaw 12 which lies on the opposite side of the anchoring member from the head 3 so that by tightening the screw the anchoring member may be firmly gripped between the head and the jaw. The jaw may have its gripping face suitably roughened or knurled as suggested in the drawing; and for economy in assembling, and also to afford a Spacing means between the swinging lever 5 and the tulcruming member 10, said jaw 12 is mounted upon the stud 4;, which serves in common for the anchoring member and the lever. j
To adjust the tension of the spring, it is merely necessary to displace the arm 10b circumferentially of the shell. For convenience in accomplishing this a tool C is provided in the iiorm of a spanner having an arcuate portion C adapted to fit the wall of the shell, and a linger C adapted to engage the arm 10b while the arcuate portion is being guided upon the cylindrical wall of the shell. Adjustment is accomplished by releasing the screw 11 while holding thev tool against the arm of the anchoring member, displacing the arm circumierentially of the shell until the supported member is sustained by the balancing arm, and 4then tightening the screw to hold the parts to their adjustment.
Since the mounting shell 1 is located eccentrically to the hinge of the member A to be supported, the balancing lever 5 is connected to said member through means of a link 13 that compensates for digression of the arcs through which the end of the lever and the point of attachment of the supporting member must swing.
