WHEEL- LIFTING JACK 2 Sheets-Sheet 1 INVENTOR. LYNNE LA MUNYON ATTORNEYS Patented Apr. 3, 1951 UNITED STATES? PATENT OFFICE WHEEL-LIFTING JACK Lynne La Munyon, Carlsbad, Calif.

Application October 19, 1948, Serial No. 55,277

in a compact unit when not in use, thus requiring a relatively small storage space. The jack is arranged so that it may be assembled very quickly.

It is proposed in this invention to provide a wheel-lifting jack that is simple in construction, compact, durable and efficient for the purpose intended.

Other objects and advantages will appear as the specification continues, and the novel features will be set forth in the claims hereunto appended:

For a better understanding of my invention, reference should be had to the accompanying drawings, forming part of this application, in which:

Figure 1 is a partial vertical sectional view taken through a rear wheel of an automobile, and illustrating my lifting jack in operative position;

Figure 2 is a side elevation of the lifting lever;

Figure 3 is an enlarged transverse sectional view taken along the line IIIIII of Figure 2;

Figure 4 is a side elevation of the base and extendible standard of my jack, the lifting lever being disclosed in section;

Figure 5 is an enlarged transverse sectional view taken along the line V-V of Figure 4;

Figure 6 is an end elevational view of Figure 4; and

Figure '7 is a side elevation showing the parts of the lifting jack in folded position.

While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made within the scope of the annexed claims without departing from the spirit thereof.

Referring now to Figure 1, it will be noted that I have shown a rear axle ll) of an automobile on which a brake drum H is mounted in the usual manner. The disc wheel A has been aligned with and moved up against the drum II.

6 Claims. '(Cl. 254-131) A jack B has raised the axle sufliciently for the tire C to clear the ground D.

The disc wheel A is provided with a central opening l2 adapted to receive the hub M. A centering stud I 5 on the brake drum projects through an opening it in the disc wheel in the conventional manner when the wheel A is applied over the hub M. A plurality of retainin studs H are insertable through openings IS in the disc wheel and are adapted to be screwed into threaded bores [9 provided in brake drum.

Ordinarily, five of these retaining studs are arranged circumferentially around the brake drum II for anchoring the disc wheel in place. I utilize the lowermost stud-receiving opening I8 when lifting the wheel into proper alignment with the brake drum H and hub M.

In its structural features, my wheel-lifting jack includes a base E having an extendible standard F mounted thereon, a diagonal brace G, and a liftin lever H. The base, standard and brace are made up of channel irons of pro gressively small cross-section that may be nested together when the jack is folded, as shown in Figure 7 of the drawings.

The base E is of sufficient length to prohibit any sideways tilting of the standard F, but is narrow enough to permit the standard to be tilted toward and away from the brake drum when the base is disposed parallel with the side of the tire C (see Figure 1). This rockable feature of the base allows the wheel A to approach and telescope over the hub l i when assembling the wheel on the brake drum.

The standard F is made in two sections, which are designated at F! and F2. The section Fl slides within the section F2 so that the two sections may be adjusted to suit different size wheels. Bolts 29 secure these two sections of the standard in adjusted position.

The brace G is hinged to the flanges 2| of the channel-shaped base E by rivets 22, with the flanges 23 of the brace facing upwardly see Figure 5). Also, the brace has its flanges 23 hinged to the flanges 24 of the channel-shaped section F2 by rivets 25. In order to secure the lower end of the section F2 to the base E, I make use of a pin 26, which is insertable through aligned openings Zia and 24a fashioned in the flanges 2i and 24, respectively.

Upon withdrawing the pin 26, thestandard section F2 is foldable into a position between the flanges 2| of the base E. At the same time, the

' brace G is-foldable into a position between the flanges 24 of the standard section F2. Spacers 21 are interposed between the flanges 2| and 23 to provide ample room between these flanges to receive the flanges 24 of the section F2 (see Figure when the device is folded.

The upper ends 2841 of the flanges 28 on the section Fl converge toward one another to provide a fulcrum 29 at the top of the standard. A pivot rod 30 is secured to the standard section Fl by rivets 3| so as to project beyond the fulcrum 29 in axial alignment with the standard F.

The leverH is made of channel iron and has an opening 32 in its web 33 to receive the pivot rod 30. The lever may be rocked up and down on the fulcrum 29 and rotated about the pivot rod 30. The flanges 34 of this lever are brought close together at their forward ends so as to be secured to a lifting hook 35 by rivets '36. This hook is dimensioned for fitting into the lowermost stud-receiving opening [8 in the disc wheel A, as clearly shown in Figure 1. At the rear end of the lever H, the flanges 34 are brought to- ;gether and appropriately rounded on top to effect a comfortable grip 134afor the operators hand.

Whe m he l itter is t e used th stand- :ardF is swung into upright position and has its lower end anchored to the base E by inserting the pin 26 through the aligned openings 2 la-and 24a in the flanges 2| and24, respectively. At this time, the brace G will oceupy the diagonal position shown in Figure 4 to give rigidity to the sta a Next, the base E is placed on the ground D closeto and parallel withthe wheel A. The lever H is lowered upon the fulcrum 29 with the pivot rod 30 passing through the opening 32 in the web of the lever (see Figures 1 and 4) and the hook 35 is inserted through the lowermost opening l8 in the disc wheel. The operator places one hand on the topmost par-t CI of the tire to steady the wheel. The other hand of the operator is utilized for pressing down on the grip end 34a of the lever I-I until the wheel is axially aligned with the hub 14.

For the purpose of aligning the stud-receiving openings ll; of the disc wheel with the threaded bores l9 in the brake drum, the wheel A may be rotated on the hook 35. Also, the wheel may be moved laterally by swinging the lever H in a horizontal plane. The centering stud it in guided through the opening I6,'and the central opening E2 of the wheel-fitted'over the hub 14. The lever H may be moved in the direction of its longitudinal axis, thereby tilting the standardF and the base E into inclined positions, as shown in Figure 1, in order to bring the disc wheel up against the face of the brake drum.

Wh n r aining studs l'ihave been inserted through upper openings l8 into threaded bores 19 to secure the wheel to the brake drum, the hook 35 is disengaged from the wheel. Thereupon, the lower studs 11 are screwed into place.

In order to fold the device, the lever H is removed from the pivot rod 30 and then the pin 2t is withdrawn. The rivets 22 and 25 act as pivots and the standard F and brace G are let down into the base E, as illustrated in Figure 7.

4 and openings 34b in the flanges 34 of the lever H. This will keep the base E, standard F, brace G and lever H in folded and nested position.

The pin 26 is provided with an eye 26a to which one end of a spring 31' is attached. The other end of this spring carries a ring 38. The spring is adapted to be drawn sling-fashion over the assembly and the ring 38 slipped over the protruding end 26b of the pin 26 to hold the lifting lever H securely in place. This produces a compact device requiring relatively small storage space.
