ADJUSTABLE SUPPORT.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed April 9, 1920. Serial No. 372,687.

T 0 all whom it may concern Be it known that I, LEONARD I. GIL- GREASE, a citizen of the United States, and resident of Reno, in the county of Washoe and State of Nevada, have invented new and useful Improvements in Adjustable Supports, of which the following is a specification.

My invention relates to adjustable supports and comprehends improvements in my prior Patent, No. 1,320,613, for supports, issued November 4, 1919.

The principal object of the present invention resides in the provision of a support including a vertically adjustable head and a handle so arranged and constructed as to lock the head against vertical move-.

ment in carrying the support, and further the handle being adapted to be disposed parallel to the support and retained against swinging away from the same when the latter is in operative position.

A further object of the invention is to provide a support of this character which includes a pivoted handle adapted to be swung to a lateral position when it is desired to carry the support and which when in such position will retain the head, and standard with which the head is telescopically engaged, against movement with respect to each other.

Another object of the invention is to provide a support principally adapted to be engaged beneath the axle of a vehicle after the same has been jacked up and to support the axle in such position and which includes a handle whereby the movable member of the support may be raised and lowered and which serves to lock the support standard and head. against movement when the support is being carried from one point to another by the handle. I

An additional object of the invention is to provide a device having the above characteristics which is simple in construction, consists of few parts, and may be manufactured and sold at a nominal cost.

With the above and other objects in mind, my invention consists in the novel combination of elements, constructions and arrangement of parts, operation and specific features, all of which will be hereinafter enlarged upon and explicitly defined in the subjoined claims, the invention being illustrated in the accompanying drawings wherein,

Figure 1 is a side elevation of a support embodying my improvements;

Fig. 2 is a vertical sectional view of the same;

Fig. 3 is an elevation taken at right-angles to Fig. 1;

Fig. d is a fragmentary side elevation showlng the handle in extended position;

Fig. 5 is an enlarged detail view illustratmg the locking elements carried by the handle in locked engagement with the support standard; and,

Fig. 6 is a similar view illustrating looking elements in normal position.

Referring to the drawings in detail wherein like characters of reference designate like parts throughout the several views, the numeral 5 designates a tubular standard provided with a base 6. Vertically adjustable in the standard 5 is a toothed supporting bar 7 provided with a supporting head 8 at its upper end adapted to engage a vehicle axle or the like to retain the same in elevated position. As is disclosed in my prior Patent 1,320,613 I provide a locking means designated in its entirety at 9 for cooperation with the toothed rack bar to retain the same in adjusted position. One face of the bar 7 is provided with a longitudinal groove 10, the ends of which stop short of the ends of the bar and engaged in this groove is a set-screw 11 extending laterally from the standard 5 which prevents the withdrawal of the bar from the standard.

Extending transversely through the head 8 at the center thereof is a relatively long pin 12, the ends of which project beyond the opposite faces of the head 8. There is provided a resilient U-shaped handle 13, the legs of which are formed with laterally disposed loops 14: adjacent their inner ends. These legs are also provided with eyes or bearings 15 pivotally and longitudinally engaged on the pin 12, the inner extremities of these legs terminating in downwardly extended opposed hooks 16 adapted to be engaged with outstanding ribs 17 formed upon the upper end of the standard 5 to lock the handle in the position illustrated in Fig. 1- to retain the tooth bar against a longitudinal movement with respect to the standard. The outstanding ribs 17 do not extend entirely across the standard, thus the laterally disposed loops it will not be obstructed during the swinging of the handle.

When it is desired to carry the support the handle is swung to the position shown in Fig. 4 and the resilient leg of the handle grasped by the operator and moved toward each other to engage the hooks 16 beneath the ribs 17.

Vith the support in the position illustrated in Fig. 4 when it is desired to elevate the tooth bar the legs of the handle are allowed to spread apart farenough for the hooks 16 to clear the ribs 17 but not far enough to permit the laterally disposed loops from moving beyond the upper edges of the standard. lVith these loops engaging the upper edge of the standard the lever may be moved downwardly with these loops as a fulcrum to raise the toothed bar. When the handle is not in use it is extended parallel to the standard and the laterally disposed loops 14 will engage the same and due to the resiliency of the legs of the handle, the handle will not accidentally swing on its pivot 12.

The embodiment of the invention illustrated and described is a practical structure but I wish here to state that the invention may be embodied in other constructions and that my limits of such embodiments are only governed by what is claimed.

What is claimed is:

1. The combination with a tubular standard and a supporting bar vertically adjust able therein, of a pin extending transversely through the upper end of the vertically adjustable member, a handle including a pair of resilient legs having eyes formed therein at one end thereof and loosely engaged on the pin, and opposed locking hooks extending from the pivoted ends of the legs and adapted to engage the upper end of the standard and lock the same against movement with respect to the lifting bar, the handle being normally disposed parallel to the standard and the locking hooks normally disengaged from the standard.

2. The combination with a support including. a stationary member and a vertically adjustable supporting member associated therewith, of a pin extending transversely through the upper end of the lifting bar and having the ends thereof extended beyond the opposed faces thereof, a resilient U-shaped handle having eyes formed at one end thereof and mounted for slidable and rotary movement on the pin, and locking elements carried by the eyes adapted to engage the standard upon moving the legs of the U-shaped handle toward each other to retain the standard and lifting member against movement with respect to each other.

3. In a support, a standard, a lifting member vertically adjustable therein, a pin extending transversely through the upper end of the lifting member and having its ends projecting laterally therefrom, a handle including a pair of resilient legs bent adjacent their inner ends to afford eyes, the latter being slidably mounted on the outstanding ends of the pin, the legs terminating in opposed hooks adapted to engage an outstanding member carried by the upper end of the standard upon moving the legs toward each other whereby the handle will be retained in a position laterally of the standard and the vertically movable member locked against movement.

at. The combination with a standard provided with an outstanding rib at its upper en d, a vertically adjustable supporting member associated with the standard, a pin eX- tending transversely through the upper end of the vertically movable supporting member and having the ends thereof projecting laterally therefrom, a resilient U-shaped handle having bearings formed at one end thereof and engaged on the outstanding ends of the pin, parallel opposed hooks carried by the pivoted ends of the handle and adapted to engage the outstanding rib upon moving the legs of the U-shaped handle toward each other whereby the supporting member will be retained against movement with respect to the standard, and laterally and inwardly extending members engaging the upper end of the standard and constituting fulcrums for the handle whereupon permitting the legs to spread apart so that the hooks will clear the rib and upon moving the handle downwardly the supporting bar will be raised, the laterally disposed members engaging the standard. upon arranging the handle parallel thereto to retain the handle against pivotal movement.
