Original No. 1,999,016, dated April 23, 1935, Serial No. 758,846, December 22, 1934. Application for reissue August 20, 1936, Serial No. 97,085
8 Claims.
The object of my invention is to provide a mechanical adjuster intended for universal application where a mechanical device is required for supporting or holding articles in various adjusted and fixed positions, such as leveling tables when on an uneven floor; taking the place of the rack and rack supporton a lifting jack; supporting the weight of an automobile when the wheel is lifted from the ground; as a door stop for holding a door ajar at any desired position, and for other purposes. I attain the objects of my invention by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a front plan applied to a leg of a table;
Fig. 2 is a horizontal section on line Fig. 1;
Fig. 3 is a front plan view of the invention with the cover plate 2 removed and with the device in the position it assumes during the step of adjusting it to a different position, with the wedge members B and 9 drawn apart as far as the spring 11 will permit;
Fig. 4 is a front plan view of the invention in an adjusted position with parts of the device which are concealed by cover 2 indicated in dotted lines;
Fig.5 is a similar view of the invention with the cover plate 2 removed; and
Fig. 6 is a side elevation of the device.
Like numerals designate like parts in each of the several views.
view of my invention Referring to the accompanying drawing, I provide a holder consisting of a base 4 and a cover 2, the sides 3 of the cover 2 engaging over the sides 5 of the base 4, as shown in Fig. 2. These members are secured to an element to be adjusted, such as a table leg A as shown in Fig. 1, by means of screws l which pierce the cover 2 as at 1 andthe base 4 as at'G, as shown in Fig. 2. I provide an upper wedge B and a lower wedge 9 each having a similar foot ill at their respective outer ends. wedge 8 has a slot H and wedge 9 a similar slot I! through which the screws l are inserted to permit free sliding movement of the wedges relative to the screws l holding the casing elements to each other and to a member to be adjusted, such as the table leg A shown in Fig. 1. Extending between the inclined face or wedge surface ii of wedge 8 and the imposed inclined face or wedge surface ll of wedge 9, is a thin flexible metal strip l5 which I have devised and which has cutturned projections ii at its ends to engage over the ends of the respective sides 5 of the base 5 ,asshowninFlg's. 3, 4, and 5, asthecasingmembers 4 and 2 are open at the ends as shown in the drawing. 7
I provide a suitable fluted spiral or other spring I1 having bent-in ends l3 attached to the respective wedges 8 and 9 as shown in Figs. 5 and 6 to retain'same in proximity to each other while permitting them to be retracted slightly from each other.
The strip of metal and 9 and'tends to convey the strain or load to the body or case of the device, thereby preventing one wedge from being forced out of position by the other wedge and facilitating close or fine adjustment. ing wedge 8 or lowering wedge 9, the other wedge being caused to follow by the connection made between the wedges by spring H but as one wedge is raised or the other wedge lowered, the engagement with the thin metal strip I5 is released so that both wedges will slide longitudinally in the casing and the strip of metal will change its shape or conformation accordingly, as will be apparent by reference to Fig. 3, as it is quite flexible. When pressure is again exerted on the wedges the strip of metal causes them to wedge against the casing and lock in position thereby completing the adjustment and making it fixed as long as desired. As an illustration, if the body or case is attached to a table leg, as shown in Fig. 4, and it is desired to level the table in order to compensate for a low place in the floor, the adjustment would be accomplished by pressing down on wedge 9 until the proper adjustment or leveling is reached, then by a slight pressure on top of wedge} it will fasten or look wedge 9 in the desired permanent .position. It will be noted that the spring l1 causes the locking wedge to follow the supporting wedge whenthe latter is moved from one position to the other to get proper adjustment.
When using this device for holding a door ajar, the adjustment is accomplished in a similar manner. The device may be made of any suitable material and in various sizes to comply with the requirements for which the article may be used.
As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
