Title: Vehicle jacking structure
IPC: B66F1/00
Filed: 1936-06-18
Abstract: 464,241. Lifting-jacks. RYERSON & HAYNES, Inc. June 18, 1936, No. 17004. Convention date, Feb. 6. [Class 78 (iii)] A ratchet lifting-jack for motor vehicles, and formed mainly of sheet metal, comprises a supporting-column with ratchet teeth on one face, a box-member carrying the operating lever and pawls substantially embracing and slidably mounted on the column together with a particular arrangement of pawls and means for reversing their action. In the form shown a toothed column or standard 2. of hollow trapezoidal cross-section is connected detachably to a cup 4 riveted to the foot 3, by means of a withdrawable pin 6 engaging the teeth. A casing 15 with engaging-means at its upper end for the bumper or other suitable car part, slides on the standard so as to project above the upper end of the standard in its raised position. A lateral extension of the casing carries the pivot 38 for the actuating lever 36 and the holding pawl 39. The lifting-pawl 45 is pivoted to the lever 36, the stroke of which is limited by slots 47 in the casing. One end of a spring 48 acts directly on a stud 49 carried by the pawl 39, while the other end is bent into a double-loop arrangement to engage the stud 51 on the pawl 45. When the lever 52 is in the substantially horizontal position shown in the Figure, it bears against the upper end of the spring 48 and the casing is raised on the fixed column by reciprocation of the lever. On the other hand, when the lever 62 is turned clockwise into an approximately vertical position the parts are set for step-bystep lowering. Rough adjustment is effected by drawing the casing manually up the standard and a rapid gravity collapse of the unloaded jack by holding the handle in one particular position in which both pawls disengage by gravity. The lifting-crutch comprises three laterally-extending members 20 furnished with inclined wings 23 and set 90‹ apart from one another.
