July 9, 1968 H. B. EHRHARDT UNIVERSAL HOISTING FIXTURE Filed May 26, 1,967

INVENTOR HENRY B. EHRHARDT United States Patent 3,391,957 UNIVERSAL HOISTING FIXTURE Henry B. Ehrhardt, Stanley J. Yaphe, 715 Fay Drive, Glendale, Calif. 91206 Filed May 26, 1967, Ser. No. 641,633 4 Claims. (Cl. 294-78) ABSTRACT OF THE DISCLOSURE This fixture is to be suspended from a hoist for the purpose of supporting a line which is to carry a load to be lifted. This invention consists of two trapezoidal shaped cheek plates, in equal and parallel spaced relation to one another, and supporting a plurality of horizontally disposed bolts, each bolt encompassed by a spacer, and mechanism adapted to control the movement of said lifting line is also suitably mounted between the aforesaid cheek plates. This mechanism includes a shaft which passes through and is secured to the center of a spur gear and of a spool on which is wound the lifting line. A line divider is mounted on two of the said bolts and spacers. A U-shaped brake shoe is secured immediately below the mechanism and the shaft extends through elongated openings in the cheek plates so that the mechanism normally rests on the brake shoe. The upper edges of the brake shoe terminate beside the spur gear so that the end of a bar or the like can be inserted between teeth of the spur gear and pried against one of the edges to lift the mechanism out of contact with the brake shoe and to rotate said mechanism to shift the position of a load that is secured to said line.

It is the principal object of this invention to provide a universal hoisting fixture that can be suspended from any type or size of hoist when it is desirable to control the lateral movement of the load being lifted.

Another object of this invention is to provide a universal hoisting fixture of the character described that can be operated by the man controlling the lifting of the load by the hoist, the mechanism of the fixture being activated by means of a manually held bar or screw-driver, as will hereinafter be described.

Still another object of this invention is to provide a universal hoisting fixture that contains a minimum number of easily replaced parts that will, with normal usage, last for a long time.

Other and further objects and advantages of this invention of a universal hoisting fixture will become apparent as the reading of this specification and claims proceeds and the appended drawing is examined.

In the drawing:

FIG. 1 is a pictorial view of this invention ready for use.

FIG. 2 is a side view of this invention.

FIG. 3 is a sectional view of this invention, taken substantially along line 3-3 of FIGURE 2, and viewed in the direction indicated by the arrows.

FIG. 4 is a sectional view of this invention, taken substantially along line 4-4 of FIGURE 2, and viewed in the direction indicated by the arrows.

FIG. 5 is a sectional view of this invention, taken substantially along line 55 of FIGURE 2, and viewed in the direction indicated by the arrows.

In the drawing, like parts are indicated by like reference numbers throughout the several views.

The reference number 7 indicates this invention in its entirety.

The invention consists of two vertically disposed

cheek plates

8 and 9, in equal and parallel spaced relation to one another. A bolt 10 passes through the upper-portion ice of each of the aforesaid cheek plates as well as through the spacer 11, thereby providing a means of suspending this invention from a hoist, not shown in any of the views of the accompanying drawing since the hoist itself is not a part of this invention. Similar bolts and similar spacers that hold the two aforesaid cheek plates together are like wise indicated by the same reference numbers 10 and 11 in the several views of the drawing. Here it is seen on examination of FIGURES 1 and 2 that this invention also embodies a drum 12 that is mounted on the shaft 13 which also supports the spur gear 14, which i also mounted on the aforesaid shaft 13. The brake shoe 15, which is U-shaped when viewed from front or back and T-shaped when viewed from above or below, normally rests on the specific two of the aforesaid bolts and spacers 10 and 11 which are located in this bottom portion of this invention and also supports the already mentioned drum 12 and the spur gear 14 since the opening 16, in which the ends of the shaft 13 ride in each of the

cheek plates

8 and 9, is elongated, as one can see by examination of FIG- URE 5 of the drawing.

A line divider 17, that encompasses the upper portion of the aforesaid drum 12 and its encompassing wire line 18, which may be replaced by a chain if so desired, is mounted on two of the often mentioned bolts 10 and spacers 11 of this invention, as one can readily see by examination of FIGURES 3 and 4 of the drawings.

The way in which this invention of a universal hoisting fixture is used is quite simple. After the two lifting eyes 19 on the ends of the aforesaid wire line 18 are suitably secured to the automobile or marine engine or other object that is to be lifted, a bar or screw driver, that is shown in phantom lines in FIGURE 3 of the drawing, and which is indicated by the reference number 20, has its outer end placed in the manner shown in the teeth of the aforesaid spur gear 14, thereby moving the gear upward in its supporting elongated opening 16, thus causing the aforesaid drum 12 to rotate on the shaft 13, thereby taking the wire line 18 in on one side and playing it (the line) out on the other side since the line is wound once around the aforesaid drum 12, thus causing the load to shift its alignment or balance. This movement of the line and its secured load will greatly facilitate the handling, movement, and installing of the engine or any other object on a truck or other object. Obviously, the bar or screw driver 20 is moved from the fixture as soon as the desired balance of the object being lifted has been obtained.

From the foregoing, it is seen that I have herein provided a universal hoisting fixture of the character described that fulfills all of the stated objects of this invention.

This invention is subject to any detail changes and/or modifications that one may care to make in so long as the changes and/or modifications fall within the scope and intent of the appended claims.

What I now claim as new is:

1. A universal hoisting fixture of the character de scribed, comprising a pair of cheek plates in equal and parallel spaced relation to one another, the said plates being secured together by a plurality of horizontally disposed bolts and spacers; and mechanism mounted between the said cheek plates, the said mechanism being adapted to support a wire line that has each end suitable for securement to a load that is to be lifted by a hoist that is to be secured to the upper end of the said fixture, the said mechanism consists of a horizontally disposed shaft whose ends project into an elongated opening in each of the said cheek plates, the said shaft supporting both a spur gear and a drum around which the said line is wound, the said mechanism also embodies a line divider that is mounted on two of the said bolts and spacers, the

, said line divider being normally located in the longitudinal center of the said drum.

2. The invention of claim 1, wherein the said fixture also contains a U-shaped brake shoe that is normally resting on the two lowermost bolts and spacers.

3. The invention of claim 2, wherein the said U-shaped brake shoe extends in width from one of the said cheek plates to the other cheek plate, the said U-shaped brake shoe appearing T-shaped, when viewed vertically from either above or below the said invention.

4. The invention of claim 2 in which upper edges of the U sha-ped brake shoe are beside the teeth of the spur gear, whereby the end of a bar or the like can be inserted 4 4 between gear teeth and the bar pried against said edges to shift the position of any load that is secured to said line.
