Application filed May 19, 1919. Serial No. 298,266.
To all whomy t may concern.'
Be it known that I, FREDERICK H. ELWERT, a citizen of the United States, residing at Chicago, in the county ot Cook and State of Illinois, have invented certain new and useful Improvements in a Flour-Bin Holder, of which the following is a specication.
This invention relates to kitchen cabinets, but more particularly to a flour bin holder thereof of the type in which the bin is supf ported in the up er part ot the cabinet and can be moved cownwardly for filling it. The principal object ot the invention is to provide means for holding the bin both in a raised and a lowered or filling position, and to assist in raising the bin from the filling position. rIhe invention consists in the novel construction and arrangements of the parts.
In the accompanying drawing l is a side elevation partly in section o a bin and holder constructed in accordancenwith the principles of the invention; and Fig. 2 illustrates a modification thereof.
A bin 1 for flour or other materials is supported in an upper compartment ot a cabinet 2 for swinging movement forwardly and downwardly therefrom by means of side supports 3 each of which has an angular slot 4 at the upper end thereof for receiving a supporting pivot 5 projecting from the bin 1 and these supports 3 are each mounted on a pivot 6 at the lower end which may be carried by a plate 7 secured on the insides of the compartment. Each support is commonly provided with a pin 8 at soine distance from the pivot 6 which moves in a curved slot 9 formed in the plate 7 for guiding and holding the support and also for constituting a stop for the support at each end of its travel.
Extending rearwardly from the two par alle] supports 3 is a connecting brace `10 toembrace the rear side of the bin 1 and to connect the supports 3 for operation to-v gether. One end of a spring 11 is attached. by means of a perforation 12 in the brace 10, at each side of the bin and the other end of this spring is attached to a pin 15 behind and below the pivot 6V and preferably supe ported by the plate 7.
In operation it will be seen that the bin l is normally held in its upright position 'oy the spring 11 which is under tension when the bin is in this position. By reason of the location of the pin 13 behind and below the pivoting point 6 of the supports 3 to the extension ot which the other end of the spring 11 is connected, the lowering movement of the supports 3 causes the spring to be moved to the other side of' the center or pivot 6, so that the action of the spring when in this position will tend to draw the supports 3 further in a downward direction. This ot course, is prevented by the engagement of the pins 8 in the slotsI 9 ot the plate 7. Thus it is evident that the springs 11 serve the triple function of holding the bin in the upper position, to hold the bin and the supports in their lowermost position, and to assist in raising the bin from its lowered position as soon as the spring is moved by the supports so that its center passes the axis of the pivot 6.
Approximately the same result can be obtained by the structure shown in Fig. 2; this consists in providing a support 14 corresponding to the support 3 with a laterally projecting arm 15 adjacent the pivot and in attaching one end of a spring 16 to a perfora-tion '17 at the end orP this arm, and attaching the other end of the spring not to a brace 18 but to a support 19 in the side of the cabinet. Then this construction is rotated to a 'forward or filling position as shown in broken outline the spring 16 will be moved past the pivot 6 so that the spring will tend to pull the support downward, thereby holding it in place in this position, and as soon as the spring is moved past the pivot 6 in the other direction, it. will assist in raising the supports and the bin attached thereto, and will hold the supports in their uppermost position.
A kitchen cabinet including an upright container, a pair of supports pivpted to the 'upper end o the container, a pair of plates fiXed in the cabinet to which the lowemr'ends lof the supports are pivoted, a projection from each support and a curved slot therefor in the corresponding plate to limit the mediate the ends thereof so that the spring will pass over the center on that line and Will draw and hold the supports at either limit of the slots and the Container Within or extended from the receptacle.
