Application filed July 27, 1917. Serial No. 183,186.

To all whom it may concern Be it known that 1, JOHN C. YOUNG, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Handles for Automobile-Jacks; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in a handle for automobile jacks and has for one of its objects the provision of a device of this character, which can be readily folded into a compact device so that the same may be stored in a considerably small space.

Another object of this invention is the provision of a novel securing means of the handle to the drive shaft" of a jack so that the handle may be readily removed and replaced upon the jack when desired.

A further object of this invention is the provision of a universal joint disposed between the securing means and the handle so that the handle may be operated at various angles with relation to the jack.

A further object of this invention is the provision of a means for locking the universal joint against movement so as to provide a rigid construction between the handle and the securing means to the jack when desired.

A'still further object of this invention is the provision of a handle for automobile jacks of the above stated character, which shall be simple, durable and eflicient, and

which may be manufactured and soldat a comparatively low cost.

With these and other objects in View as will become more apparent as the descrip-" tion proceeds, the invention consists in certain novel features of construction, nation and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a side elevation of a handle for automobile jacks cc. structed in accordance with my invention, I

Fig. 2 is a top plan view of the same,

Fig. 3 is a fragmentary longitudinal sectional view illustrating the construction of the universal joint,

combilow securing Fig. 4 is a similar view with the locking means disposed over the universal joint to establish a rigid construction,

Fig. 5 is a fragmentary longitudinal sectional view of a hinged connectionbetween the pair of sections and the handle,

Fig. 6 is a similar view of a connection between the pair of sections of the handle and anotherconnection between another pair of sections of the handle,

Fig. 7 is a transverse sectional view taken on the line 7-7 of Fig. 2, illustrating the means of locking the drive shaft of a jack to the securing means of the handle,

Fig. 8 is a transverse sectional view taken on the line 8-8 of Fig. 2, illustrating the means of looking a sleeve upon one section of the handle,

Fig. 9 is a transverse sectional view taken on the line 9-9 of Fig. l.

Referring in detail to the drawings, the numeral 1 indicates one section of a handle, which has one end disposed at right angles as illustrated at 2- to which is secured a clamp 3. The clamp 3 has an extension 4:

of substantially U-shape formation in cross section, which is pivoted to an L-shape member 5, constituting the hand grip of the handle. The extension 4 being of U-shape formation will receive between its arm portions, the member 5 and prevent it from swinging on its pivot 8.

The section 1 has connected to its other end, a double clamp 9, which has extensions 10 and 11 that are of substantially U-shape formation in cross section. The clamp 9 is pivoted to the section 1 as at 12, and the extension 11 is adapted to receive and grip the section to prevent it from swinging accidentally upon its pivot. The clamp 9 has a section 14: pivoted thereto as at 15 over which the extension 10 extends. The exten-' sion 10 is adapted to receive and grip the section 14: to prevent it from swinging upon its pivot 15. The section 14 has a universal joint 17 connected thereto, which consists of a pair of relatively spaced arms 18, which are pivotally connected to the section 14 as shown at 19. The arms 18 are apertured to receive the pin or bolt 20, which is carried by arms 21 formed upon a hollow securing member 22, whereby the section it is capable of being disposed at an angle with the securing member 22 when desired. The holmember 22 is provided with oppositely disposed slots 23, which open out through the ends of the sec member 22 it'd Tp d

for the purpose of receiving a pair of oppositely disposed lugs 24 upon the drive shaft 25 of a well known constructed jack. The securing member 22 is screwthreaded as at 26 and has threaded thereon, a locking member 27, which has its outer face shaped to form gripping faces, whereby a person may grip it to turn the same on the threads 26. The locking member 27 is provided with oppositely disposed grooves 35, which are adapted to be registered with the slots 23 in the securing member 22 when placing the same upon the lugs 24 of the drive shaft 25. As the lugs 24 have been positioned within the slots 23, the locking member 27 is turned in engagement with the lugs 24, moving the grooves 35 therein, out of registration with the slots 23 thereby locking the lugs 24 against withdrawal from the slots 23, thus establishing an efiicient connection between the securing member and the drive shaft 25.

A sleeve 28 is slidable upon the sectlon 14 and is provided with a lengthwise slot 29 that has locking branches 30 at each end thereof. A pin 31 is carried by the sectlon l4 and slides within the slot 29. One end of the sleeve 28 isgprovided with bifurcations to form arms 32 that are bent out-.

wa'rdly and laterally and have a ring 34 connected to their free ends. When desiring to lock the universal joint 17 against movement, the sleeve is moved in the direction of the universal joint, moving the ring 34 and arms 32 over the universal joint, permitting the ring 34 to engage the securing member 22' and by slightly rotating the sleeve 28, the lug 31 is moved into one of the locking branches, preventing the arms 32 from dis engaging the universal joint, thus providing a rigid construction. This rigid construction being preferably employed when inserting a jack under an automobile or like vehicle by pushing upon the hand grip 5 having the sections 1 and 14 disposed in a horizontal plane and after the jack has been properly positioned, the sleeve 28 may be slid upon the section.14 to disengage the arms 32 from the universal joint 17 and pin 31 engaged with the other locking branch of slot 29 so that the hand grip 5 may be disposed at an angle with relation to the jack so. as to easily operate said jack.

While I have shown and described the preferred embodiment of my invention, it

will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. A handle for jacks comprising a pair of sections,

a clamp pivoted to each of said gaging the hand grip to form a rigid construction, and means for detachably connecting the other section to a jack.

I 3. The combination with a jack including a drive shaft having oppositely disposed lugs, of a member, a hand grip secured to said member, a universal joint connected to said member, a hollow securing member connected to the universal joint and having oppositely disposed slots to receive said lugs, screwthreads on said securing member, and a locking member having oppositely disposed notches to register with the slots of the securing member and threaded on said securing member for retaining the lugs in the slots when the notches are turned out registration with the said slots.

4. A handle for jacks comprising a member, a hand grip connected to said member, a universal joint connected to said member, a securing means connected to the universal joint and detachably connected to a jack, a sleeve slidable on said member, arms carried by said sleeve, and a ring carried by said arms and adapted to engage the securing member and permit the arms to overlie the universal joint to provide a rigid construction between said member and securing member.

5. A handle for jacks comprising a member, a hand grip connected to said member, a universal joint connected to said member, means connecting the universal joint to a jack a sleeve slidable on said member and having oppositely disposed slots, means on sa d sleeve for engaging the universal joint, said slots having ofiset locking branches, and oppositely disposed lugs carried by said member and disposed in the slots and adapted to move in the locking branches for holdlngsaid means upon the sleeve into engagement with the universal joint, and for holdmg said sleeve from engagement with the universal joint.

In testimony whereof I aflix my signature in presence of two witnesses.
