Abstract
Abstract An adjustable support member and a dual anchor for mobile homes and other instrumentalities which require leveling by jack means and require anchoring against being moved off of the support members by high winds or other hazards. The present structure is so constructed as to provide a screw jack which bindingly and detachably engages the lower faces of beams which screw jack is so constructed as to enable the leveling of the mobile home or the like. Further an earth engaging anchor extends up through the base of the jack, and the base of the jack is secured thereto, as by a wedge, so as to prevent relative movement between the frame of the mobile home, or the like, and the terrain. A still further anchor for the mobile home or the like is provided by a band which passes over the mobile home or the like, which band is secured to the base of the jacks.

Claim 1
Independent Claim
328 words
A combination jack, anchor and hold-down apparatus for an instrumentality, which apparatus comprises; a. a base, 1. said base having a hole formed therethrough, b. an anchor member extending through said hole in said base to form an anchor with the ground, 1. mechanical means detachably securing said anchor to said base, c. an upwardly extending, screw threaded, screw receiving member secured to said base, d. a screw threaded member threadable engaging said threaded screw receiving member and extending thereabove, 1. a head on said screw threaded member and secured thereto for rotation therewith to enable the turning of said screw threaded member, 2. a first apertured plate on the upper end of said screw threaded member, 3. a reduced end portion of said screw threaded end portion of said screw threaded member passing through one of said apertures in said first apertured plate in journaled relation, 4. a head secured to the reduced end portion of said screw threaded member above said first apertured plate to enable relative rotation between said plate and said screw threaded member, but restraining said plate against relative longitudinal movement with respect thereto, 5. spacer elements secured to the upper face of said first apertured plate on at least two sides of said head secured to the upper end of said screw threaded member and being of greater thickness than said head attached to said screw threaded member, e. a second apertured plate fitted on said spacer members and supported above said head on said reduced end portion of said screw threaded member, f. at least one apertured, detachable hold-down bracket on said second apertured plate and having the aperture therein in register with the apertures of said first and second apertured plates, 1. a screw threaded bolt fitted through said apertures in said first and second plates and said bracket to bindingly engage said bracket with a portion of said instrumentality to prevent relative movement thereof with respect to the ground.
