Abstract
Abstract An engine mount wherein the engine carries two oppositely-moving jaws adad to clamp against opposite side surfaces of a hold-down element carried by the vehicle. The jaws are actuated for opening or closing movements by means of a single screw extending through both jaws. The screw threads engaged with one jaw are right-handed, and the screw threads engaged with the other jaw are left-handed, for producing the desired jaw motions. The jaws and actuator screw are freely adjustable as a unit whereby the jaws apply equal pressures on the hold-down element.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
An engine mount comprising a vehicle-attached base; an engine-attached hollow rail adapted to rest on the base; said base having an engine hold-down element adapted to project through an opening in a lower surface of the rail so that said element assumes a centralized position in the rail interior; two spaced-apart jaws slidably positioned within the rail at opposite sides of the hold-down element; and a screw threaded through said jaws for moving same into clamped positions against opposite side surfaces of the hold-down element; the screw threads engaged with one jaw being right-handed, and the screw threads engaged with the other jaw being left-handed, whereby the jaws move simultaneously toward the hold-down element; the jaws and screw being freely adjustable as a unit on the rail, whereby the jaws apply equal pressures on the hold-down element; said screw having an actuator end located outside the hollow rail; one of said jaws having a tubular shield surrounding the screw actuator end to obstruct access thereto when the jaws are spread apart to a maximum permissible distance.
Claim 2
Dependent Claim
176 words
An engine mount comprising a vehicle-attached base; an engine-attached hollow rail adapted to rest on the base; said base having an engine hold-down element adapted to project through an opening in a lower surface of the rail so that said element assumes a centralized position in the rail interior; two spaced-apart jaws slidably positioned within the rail at opposite sides of the hold-down element; and a screw threaded through said jaws for moving same into clamped positions against opposite side surfaces of the hold-down element; the screw threads engaged with one jaw being right-handed, and the screw threads engaged with the other jaw being left-handed, whereby the jaws move simultaneously toward the hold-down element; the jaws and screw being freely adjustable as a unit on the rail, whereby the jaws apply equal pressures on the hold-down element; said screw having an actuator end located outside the hollow rail; one of said jaws having a tubular shield surrounding the screw actuator end to obstruct access thereto when the jaws are spread apart to a maximum permissible distance.
Claim 3
Dependent Claim
102 words
The engine mount of claim 1 wherein the tubular shield is keyed to the screw for axial movement therealong; said shield being rotatably swivelled on said one jaw for free movement therearound, whereby the shield can be manually turned to rotate the screw and simultaneously advance the shield along the screw surface in accordance with the resultant travel of the connected jaw; said shield being oriented on the screw so as to substantially conceal the actuator end when the jaws are spread apart a maximum permissible distance, whereby initial movement of the screw must be accomplished by manual manipulation of the shield.
Claim 4
Dependent Claim
92 words
The engine mount of claim 1 wherein the tubular shield is keyed to the screw for axial movement therealong; said shield being threadably connected to the rail so that the shield can be manually turned to rotate the screw and simultaneously advance the shield along the screw surface; said shield being oriented on the screw so that the shield substantially conceals the actuator end of the screw when the jaws are spread apart a maximum permissible distance, whereby initial movement of the screw may be accomplished by manual manipulation of the shield.
