TOP-SUPPORT FOR TALKING-MACHINE AND OTHER CABINETS.
Specification of Letters Patent.
Application filed March 81, 1913. Serial No. 757,865.
To all whom it may concern Be it known that I, FRANK L. CAPPs, a citizen of the United States, of Bridgeport, Connecticut, have invented a new and useful Improvement in Top Supports for Talking-Machine and other Cabinets, which invention is fully set forth in the following specification.
My invention relates to cabinets for talking machines and other devices in which a hinged top is employed, and has for its object to provide efiicient and convenient means for supporting the top in its raised or elevated position to afford access to the interior of the machine, and for readily lowering the top. As heretofore constructed, the top-retaining means for such cabinets have beenof such character that, in the act of lowering the top, one hand had to be employed to support the top and the other means.
Afurther object, therefore, of the present invention is to provide means whereby the top-retaining means may be readily released, and the top lowered by the use of but one hand of the operator.
With this object in view, the invention consists, generally stated, in a toggle construction which, when the toggle is extended, operates to hold the top elevated, combined with suitable means, such as, a pushrod, for breaking the toggle, and permitting the lowering of the top, the push-rod having a part projecting to the exterior of-the top, in position to be actuated by the thumb of the same hand that grasps the top for lowering it.
The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustrating the invention, is shownin the accom- I pose.
In said drawings- Figure 1 is a perspec-' tive view of a cabinet with my invention applied thereto, with: the top elevated; Fig. 2 is a vertical 'cross-section'ofa cabinet with the top closed, showing my retaining device in side elevation,- the dotted lines indicating the position of the parts with the top elevated; and Fig. '3 is a broken vertical section through the cabinet to the rear of the top-retaining device looking toward the] front of the cabinet.
Referring to the drawings, in which like reference numerals indicate corresponding parts, the cabinet is shown as composed of a bodyl having a top 2, hinged thereto at 3. A toggle-link 4 is pivoted to the top 2, preferably by securing a bracket-arm 5 to the top and pivotingthe link to said bracketarm at 6. A second toggle-link 7 is pivoted,
in any suitable manner, to the body of the cabinet at 8, the pivot-point 6 being above, and the pivot-point 8 below, the line where thetop of the cabinet meets the body thereof. As clearly shown in the drawing, one
'of the links (in this case the link 4 connected to the top) has its outer pivot ofl'setfrom the longitudinal axis of the link. The two toggle-links 4 and 7 are pivoted together at 9, and on the end of the link 4, prolonged beyond the pivot-point 9, is a stop 10 composed of a part projecting at right-angles to the plane of the links 4. and 7 so that the stop will engage the link 7, in the act of raising the top 2, slightly, after the axis of the pivot 9 has passed a straight line extending between the-pivots 6 and 8, as clearly shown in Fig. 1 in full lines and Fig. 2 in dotted lines. Ofi'setting of the pivot 6 makes it possible for the stop 10 to be so placed as to hold the links with their longitudinal. axes forming one straight line as clearly shown in Fig. 2. This construction enables the links to make a much better appearance than they would if positioned at an angler-to each other. With the construction shown and described, the weight of the top acts to hold the toggle-open, and to force the pivot 9 to theleft, as shown in Fig. 2,and to lower the top, it will be evident that it is necessary to break the toggle to the right by forcing the pivot-pin 9 to the right of the line between the pivots 6 and 8.- For accomplishing this purpose, 'I provide any suitable means whereby the operator may impart the proper thrust upon the toggle.
As here shown, such means assume the form of a push-rod 11, pivotally attachedto the toggle 4 at'a point 12, located in the. enlarged end 13 of the link 4. This enlargement 1'3 ofthe end of the link 4constitutes an oifset to the Patented June 13, 1916. I
general form of the link, and in effect makes of the link 4 a bell-crank lever, one of whose arms extends between the pivots 6 and 9,
and the other between the pivots 6 and 12,
the latter of which is the short arm .of the bell-crank lever. A very small movement of this short arm at the point 12 will beconverted into a'much more extensive movement of the long arm at, the point 9, the pivot between the two toggle-links. The pivot 12 is so located that when the toggle is broken, as shown in full lines in Fig. 2, the axis of the rod 11 approximately intersects the axis of the pivot 6. In effect, upon inturned flange or other abutment 15, and
a spring 16 reacts between said abutment and a button'17 onthe end of the rod, which button is of a diameter to permit it to-slide freely within the-sleeve. The proportions of the parts are such that when the top is in lowered position, as shown in full lines in Fig. 2, the button 17 lies flush with the outer end of the sleeve 14, but when the parts arein elevated position, as shown in Fig. 1, the button 17 protrudes from the sleeve 14. This is due to the fact that the pivot-point 12, whereby the rod 11 is connected to the link 4, is moved to the rear in the act of lowering the top.
The result of this construction is (the top being elevated) that, when the thumb of the operator is applied to the button 17, and the point :12 forced rearward by thethrust on the rod 11, the link 4, and with it the pivot-point 9, is moved to the rear of a straight line connecting thepivot-points 6 and 8 of the toggle, thereby breaking the toggle, and permitting it to be closed and the-top to be lowered, as clearly shown in full lines in Fig. 2.
It will be apparent that, by this construction, the opening movement of the top is limited; the weight of the top serves to hold the retaining device in position to keep the top elevated; and that the operator may seize the top when elevated with his left hand, and by pressing upon the button 17 with the thumb thereof, break the toggle and readily lower the top. Furthermore, the. parts of the device are efiiciently concealed, so that they do not mar the appearance of the cabinet as a whole.
Various modifications may be made in the proportions and arrangement of the parts, without departing from the spirit of the invention defined in the accompanying claims.
What is claimed is 1. In a cabinet, the combination of a body and a top hinged thereto, with a. toggle for retaining the top elevated, the said toggle being entirely within the cabinet when the cabinet is closed, and a push-rod positioned in the cabinet and carried by the top and engaging the toggle, whereby the latter may be broken to permit the top to be lowered.
2. In a cabinet, the combination of a body, a top hinged thereto at one edge and provided with side and end walls and a top wall, a toggle for retaining the top elevated, the said .toggle being entirely within the cabinet when the cabinet is closed, and a push rod mounted within the said top and engaging the toggle to cause it to be broken. 3. In a cabinet, the combination of a body, a top hinged thereto at one edge and provided with side and end walls and a top wall, a toggle for retaining the top elevated, the said toggle being entirely within the cabinet when the cabinet is closed, a push button carried by the top at a point remote from the hinged edge, and a push rod mounted within the said top and extending from the push button to the toggle to cause the latter to be broken.
4. In a cabinet, the combination of a body and a top hinged thereto, with a toggle for retaining the top elevated, the said toggle being entirely within the cabinet when the cabinet is-closed, one of the toggle links being pivotally' connected to the body and one to the top, a stop limiting themovement of the toggle on one side of its fully open line, and a push-rod carried by the top and engaging the toggle and operable to break it to permit the top to be lowered 5. In a cabinet, thecombination of a body and a top hinged thereto, with 'a toggle having one link pivoted to thefbody and one to the top, a push-rod pivoted to one of the toggle links near its pivot-point, and a spring associated with said push-rod for yieldingly holding said toggle in open or extended position.
6. In a cabinet, the combination of a body and a top hinged thereto, with a toggle retaining the top elevated, said toggle being located within the. cabinet, a push-rod engaging the toggle and operable to break the toggle to lower the top, said rod being within the cabinet but having a part projecting out through the wall thereof, and a spring engaging the push-rod and thereby acting to yieldingly hold said toggle in open or extended position.
' 7. In a cabinet, the combination of a cabinet body, atop hinged to the body along one edge, two toggle links pivoted together and having their outer ends pivoted respectively to the top and to the body, one of the end pivots being at one side of the longitudinal axis of the corresponding link and the other pivots being in the longitudinal axis, means for limiting the relative movements of the two links with the said longitudinal axes forming one straight line, a push rod carried by the top for moving the links out of the straight line position, and a spring for automatically moving the links into the straight line position.
8. In a cabinet, the combination of a cabinet body, a top hinged to the body along one edge, two toggle links pivoted together and having their outer ends pivoted respectively to the top and to the body, and a push rod pivoted at one end to one of the links near its outer pivot, the axis of the push rod approximately intersecting the' axis of the said outer pivot when the toggle is broken.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
