Application led July 25, 1917. Serial No. 182,673.

To all 'whom 'it may concern:

Be it known that I, ARTHUR E. HALL, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Jack-Guide, of which the following is a full, clear, and exact description.

This invention relates to a guide or holder for acks and has for an object the provision of an improved construction which coacts with a jack for holding the jack in place while being operated for elevating an article,

Another object in view is to provide an improved guide or holder for an automobile jack which is provided with an operating chain whereby the jack may be forced under the axle of the automobile without the operator getting under the automobile.

A further object of the invention is to provide a removable handle or guide for a jack whereby the jack may be placed at any desired point under an object while the workman may remain at a given point.

In the accompanying drawing Figure 1 is a side view of a jack and a guide disclosing' an embodiment of the invention.

Fig. 2 is a sectional view through Fig. 1 on line 2 2.

Fig. 3 is an enlarged detail perspective view of the structure shown in Fig. 2, the parts being shown separated for the purpose of illustration.

Fig. 4 is a detail perspective view of a slightly modified form of the invention.

Referring to the accompanying drawing by numerals, 1 indicates the base of a ack 2, said jack being operated by a chain 3, which chain may be of any desired length. This jack is now on the market and is a Very desirable structure, as it allows the workman to stand at a distance and pull the chain for operating the jack so that the jack may bc placed under the axle 4, for instance, of an automobile and then the workman may operate the jack at any suitable distance. This advantage is very desirable as it allows the j ack to be placed in very restricted quarters and yet the jack operated properly from a convenient point. After the jack has been placed in position a chain 3 is pulledfor elevating the lifting member of the jack. Quite often the strain on the ack will cause the jack to move out of its correct position or become upset, especially if the parts are stopped up somewhat with dust. In order to prevent this and to properly hold the jack in position a guide or holder 6 is provided which is formed with a body 7 preferably threaded at each end so that one end may receive a fitting 8 through which the sliding or telescoping section 9 passes, said section also extending into the body 7 which is hollow. A thumb screw 10 is provided in the fitting 8 for locking section 9 in any desired position.4 A transverse bar 11 is provided on the outer end of section 9 so that the entire guide or holder 6 may be operated and the ack vmay be properly positioned.

A U-shaped member 12 is provided at the end opposite fitting 8, said member being preferably provided with a threaded portion which is threaded on to the body 7, though if desired it could bemade integral with the body and also if desired fitting 8 could be eliminated and the set screw fitted into the body 7. rlilhe U-shaped member 12is arranged so that the tines or fork members 13 and 14 shall extend into the fitting 15 on opposite sides of ,the web 16 extending from base 1. Stop pins 17 and 18 are provided in the tines or fork members 13 and 14.- for limiting the .inward movement of member 12 when assembling the same with the jack 2. A spring 19 is rigidly secured to member 12 and is provided with an aperture 20 designed to accommodate the pin 21 arranged on the titting 15, over which it snaps when the parts are assembled. rl`his will revent the guide or holder from accidental y becoming loose and will allow the operator to move the jack back and forth as desired for properly positioning the same beneath a given object. In applying the device to jacks now in use fitting 15 is made separate and rigidly secured to the jack, as shown in Fig. 3, but when the parts are manufactured together the jack 2 is preferably formed with the integral fitting 15', as shown in Fig. il.

In operation, the fitting 15 may be secured to any suitable jack, as for instance the kind shown in Fig. 1, which is provided with the chain 3. The holder 6 may then be applied and the jack placed at any suitable point beneath an automobile or other object without requiring the operator to get beneath the automobile or other' object. If necessary the operators foot may be placed upon the transverse bar 11 and the parts held in proper position while the chain is pulled for operating the jack. When it is desired to place the jack in a tool box it may be easily removed from beneath the automobile and the holder or guide disconnected from the jack by raising the spring 19 from off the pin 21 and then pulling the member 12 from the fitting. The section 9 may be entirely removed from the body 7 or may be'telescoped therein so as to reduce the length of the parts, and then the various members stored in the tool chest.

lVliat l claim is l. 1n a device of the character described, a body formed with a fork at one end, a spring arranged on said fork having an opening therein, a fitting for receiving said fork, means for causing the spring to lock the fork into said fitting, and means for connecting said fitting with a jack.

2. ln a device of the character described, the combination with a jack provided with a chain for operating the same, said chain extending to an appreciable distance'from the jack, of a holder extending a distance from the jack, means for connecting said magies holder with the` jack, and stops arranged on said holder for limiting the movement of the holder toward the jack, said stops also acting as means for causing a movement of the holder to move' the jack, whereby the same may be pushedbeneath an object.

3. In a device 'of the character described, the combination with a'jack provided With a socket member arranged on the base, of a comparatively long bar acting as a handle or holder, havin@ one end extending into said socket member, and means for locking said end to said base.

4. lin a device of the character described, the combination with a jack of a socket member arranged on the base of said jack, a guide or holder formed with a air of arms spaced apart and with the handle -portion extendino an appreciable distance ARTHUR EDWARD HALL.
