' TOOL Filed July 2, 1937 3 Sheets-Sheet 3 Inventor 5 By if {8 My m A iipmeys Patented June 6, 1939 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to new and useful improvements in tools particularly for automobile repair shops but it is to be understood, of course, that a device in accordance with the presout invention may be used for any purpose for which it may be found adapted and desirable.

The primary object of the invention is to provide, in a manner as hereinafter set forth, a tool of the aforementioned character embodying a novel construction, combination and arrangement of parts through the medium of which king pins, bushings, bearings, spring perches, etc., may be expeditiously removed and replaced with a minimum of effort.

Another very important object of the invention is to provide a tool of the character described embodying a construction which is such that a substantially conventional hydraulic or mechanical jack, particularly the former, may be used as the go source of power.

Other objects of the invention are to provide a tool of the character set forth which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specifica- 0 tion, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 13 is a view in horizontal section, taken substantially on the line |3-|3 of Fig. 12.

Figure 14 is a view in elevation of the rod which 16 is used for removing shackle pins or bolts.

Referring now to the drawings in detail, it will be seen that the reference numeral I designates a substantially fiat, rectangular base of suitable material, preferably metal, having formed there- 20 in a plurality of slots 2. Threaded for adjustment in the lower side of the base I is a plurality of supporting legs 3. The reference numeral 4 designates a hydraulic jack which is mounted on the base I, said jack comprising a slidable tubux other end portions of the arms 6 extend through the slots 2 and are adjustably anchored therein through the medium of cross pins 8.

A metallic member 9 is provided which is adapted to rest on or against the work and which is provided with inwardly inclined marginal portions ID with which the hooks l are engageable, as illustrated to advantage in Fig. l of the drawings. The member 9 is further provided with an, opening H for the passage of the king pin as it is removed.

A metallic rod I2 is provided for actuation by the jack 4. The rod 12 includes an enlarged end portion l3 which is adapted to be inserted in the upper end portion of the tubular piston 5 of the jack 4, together with a flange I4 which rests on the upper end of said tubular piston 5. At its other end, the rod 12 is reduced, as at [5, this end of said rod being engageable with the king pm.

In Figure 1 of the drawings, the reference numeral l6 designates a spindle assembly on one end of the front axle ll of an automobile. The king pin which connects the spindle assembly IE to the axle I1 is indicated at l8. It is thought that the manner of using the device for removing king pins will now be readily apparent. The base I and the jack 4 are positioned beneath the work, the rod I2 is mounted in the jack piston 5, the member 9 is mounted on top of the spindle assembly 5 in a manner to encircle the head of the king pin, after which the hooks I of the arms 6 are engaged with said member 9. The jack 4 is now actuated to raise the rod l2, thus forcing the king pin it out of the spindle assembly l6 and the axle H.

To meet various conditions, such as those encountered on difierent makes and models of automobiles, a substantially rectangular metallic member l9 (see Fig. 7) is provided for use in lieu of the member 9. The substantially rectangular member l9 comprises inwardly inclined marginal portions 20 for" engagement by the hooks I.

In Fig. 6 of the drawings, there is shown a hook engaging member which is particularly adapted for use in removing spring perches on the front axles of certain types of automobiles, particularly the Ford. This member is designated generally by the reference numeral 21! and comprises a substantially U-shaped element 22 the legs 23 of which are adapted to straddle the usual radius rod of the automobile. Slidably mounted on the legs 23 is a removable block 24. The legs 23 are provided with inwardly inclined upper surfaces 25 for engagement by the hooks 1.

When the member 2| is used, the closed end portion of the U-shaped element22 rests on the axle I1 and the legs 23 straddle the spring perch to be removed and the adjacent end portion of the radius rod. The block 24 is then slipped on the legs 23 and rests on the radius rod after which the hooks I may be engaged with said legs 23. The operation for removing the spring perch is now substantially similar to that hereinbefore described for removing a king pin.

In Figs. 9 to 13, inclusive, of the drawings, there is shown an arrangement which is particularly adapted for removing and inserting bushings, such as those for the king pins of an automobile. When this bushing removing and inserting means is in use it will be understood that the spindle assembly has been removed from the axle. The reference numeral 26 designates a metallic plate member which is engageable with the spindle assembly and which has formed therein slots 27 which accommodate the hooked end portions of the arms 6 for permitting the hooks I to be engaged with said plate. The reference numeral 28 designates a rod having a reduced end portion 29 which is adapted to be inserted in the tubular jack piston 5, said reduced portion 29 providing a shoulder 30 which rests on the upper end of said jack piston. The other end portion of the rod 28 is reduced, as at 3|, thus providing a shoulder 32. The reference numeral 33 designates a new bushing to be inserted which is mounted on the reduced portion 3| of the rod 28 and rests on the shoulder 32. A slidably mounted sleeve 34 on the rod 28 is adapted to be slipped over the bushing 33 for preventing expansion or bulging thereof under pressure.

When using this bushing removing and inserting arrangement, the plate member 26 is engaged with the top of the spindle assembly, for example, and the new bushing 33, which is mounted in position on the rod 28 and enclosed by the sleeve 34, is engaged with the old bushing in the lower bearing of said spindle assembly. The jack 4 is then actuated to force the new bushing 33, through the medium of the rod 28,

upwardly into the bearing thus forcing the old bushing upwardly out of said bearing and into the space usually provided on the spindle assembly for the axle. The spindle assembly may then be inverted and the bushing in the upper bearing thereof may be removed and replaced in a similar manner. Should it be desired to simply remove the bushing without inserting a new one, this may be done by inserting the reduced end portion 3| of the rod 28 in the bushing and engaging the shoulder 32 with one end of said bushing. Also, both bushings in the spindle assembly may be removed in this manner. The plate member 26 has formed therein an opening 35 in which the rod 28 may be mounted when performing certain work.

In Fig. 14 of the drawings, the reference numeral 36 designates a rod which is particularly adapted for removing spring shackle bolts. The rod 36 comprises an end portion 31 which is engageable in the tubular jack piston 5, together with a flange 38 which is adapted to rest on the upper end of said jack piston. In the other end portion of the rod 36 is a threaded socket 39 having a smooth counterbored or enlarged outer end portion 40. The rod 36 is adapted to be screwed on one of the usual projecting threaded end portions of the spring shackle bolt for forcing same out under pressure from the jack 4. Of

course, a suitable member substantially similar to those shown in Figs. 5, 6, 7 and 10 but adapted for this particular operation is provided for anchoring the arms 6. Also, a new shackle bolt may be threaded into the socket 39 and pressed into position. Still further, the rod 36 may be engaged directly at one end with a shackle bearing for removing same.

Shoulders 4| are provided on the free end portions of the arms 6 adjacent the hooks l on which the plate 26 is engageable for preventing said arms 6 from being inserted too far through the slots 21 when the tool is being prepared for the removal of king pin bushings. This is shown to advantage in Figs. 3 and 9 of the drawings.

It is believed that the many advantages of a tool constructed in accordance with the present invention will be readily understood and although preferred embodiments are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A tool of the class described comprising a base having a plurality of elongated slots therein, some of the slots being parallel to other of the slots and one slot extending at right angles to the other slots, adjustable legs threadedly mounted in said base, arms of a width to extend through the slots, cross pins on said arms engaged beneath the base for securing the arms thereto for swinging and sliding movement, a member adapted for engagement with the work, hooks on the other ends of the arms engageable with said member, the hook portion of each arm being of reduced thickness to form shoulders at the junction of the reduced part with the rest of the arm, below the hooks, said shoulders forming seats for the work engaging member, a jack mounted on the base and including a tubular piston, and a rod removably mounted in said piston and operatively engageable with the work.
