To all whom it may concern.'

Be it known that I, ALBERT A. CooN, citi'- zen of the United States, residing at Hutsonville, in the county of Crawford and State of Illinois, have invented certain new and useful Improvements in Wagon-Jacks, of which the following is a specication.

This invention relates to hoisting apparatus and refers particularly to a hand operated jack.

An object of this invention is to provide a device which is to be employed particularly when it is desired to apply grease to wagon axles, and for this purpose the invention comprises a jack for raising the axle which is provided with an attachment thereto upon which a grease-pot is supported, and also a rack for supporting the wrench and the nut when the wheel of the vehicle is being removed.

Another object of this invention is to construct a jack which enables the operator to stand in an upright position thereby lessening the fatigue incident to operating devices of this character when a number of wheels are to be greased.

The invention further aims to produce a device of this character which is applicable to vehicles of different heights, as wagons, riding plows, cultivators and the like, and one which may be readily and quickly adjusted to accommodate the same to such conditions.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view of the complete device. Fig. 2 is a detailed viewof the post and o erative parts connected therewith disclosing a modified form 0f the gravity clutch. Fig. 3 is a top plan view of the complete device as disclosed in Fig. 1. f

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings the numeral 10 designates a base upon which a post or standard 11 is positioned adjacent one end thereof and reinforced in such position by means of a brace 12 which is diagonally positioned between the opposite extremity of the base 10 and a point intermediate upon the adjacent edge of the post 11. The post 11 is provided with a binding link 13 which is disposed about the'same and which' is provided upon its forward extremity with ears 14 between which is pivotally secured the lower extremity of a lifting bar 15. The lifting bar 15 is provided with a plurality of notches 16 equidistantly spaced upon the inner edge thereof for the reception of a loop 17 which is disposed about the lifting bar 15 and which carries an outwardly extended foot 18 for engagement with the device to be raised. The foot 18 is disposed upwardly at an obtuse angle to the loop 17 and is provided upon its outer extremity with a iiange 19 for tha-purpose of insuring a rigid engagement with the device to be raised. The up er extremity of the lifting bar 15 is pivotal y supported between lugs 20 which are formed upon the forward extremity of a handle 21.

The handle 21 comprises a 22 which are positioned in ara el and which are secured together at tieir rear extremities, the rear extremities being diverged forwardly to dispose the same upon the opposite sides of the post 11 where the same are pivotally mounted upon a bolt 23 and have their outer extremities converged and formed into the lugs 20. The levers 22 are provided intermediate of their length with a rest 24 which com rises a portion of metal bent U- shaped an secured at its opposite extremities against the inner faces of the levers 22 and which is adapted to receive the shank of a wrench 25 for the purpose of supporting the same in an operative position when not in use.

The upper extremity of the post 11 is provided with-a gravity clutch which is pivotally disposed thereon and which comprises a fork 26, the extremities of the arms of which are pivotally disposed on the post 11 to support the clutch, the fork carrying upon its rear extremity an elongated link 27 and a handle 28 which is rearwardly and upwardlyv extended from the link 27. The elongated link 27 is disposed about the u per extremity of a rod 29 which is rigidly isposed upon the rear end of the binding link 13 and extended upwardly therefrom parallel to the post 11.

The up er extremity of the ost 11 is provided wit a bracket 30 whicicomprises a base ortion positioned horizontally and provide at the rear end thereof with an arcuate flange 31 for the reception of a grease-pot of any desired formation, which in most cases is of cylindrical form, and which is secured upon the bracket 30 by means of a pin 32.

air of levers f In the modification disclosed in the drawings the handle 33 is provided with a gravity clutch which comprises fork arms 34 secured against the inner faces of the levers which comprise the handle 33 adjacent the rear edge of the post 35, the fork arms 34 being terminated at their rear extremities in an elongated link 36 which is dis osed about a rod 37 whichis rigidly carriedp by a binding link 38 disposed upon the post 35. The elongated link 36 is provided with a handle 39 by means of which the same is adapted to be raised when it is desired to release the rod 37 to permit of the sliding of the binding link 38 downwardly upon the post 35.

The operation of the device is as follows3- The jack is positioned adjacent the axle of the vehicle or other devices to be raised when the foot 18 is raised to admit of the sliding of the loop 17 to enter in the notches 16 according to the height required in order to bring the foot 18 into proper adjustment beneath the axle. The handle 21 being normally in a raised position holds the lifting bar 15 downwardly and upon the depression of the rear extremity of the handle 21 the lifting bar 15 is raised and caused to impinge the foot 18 against the under face of the axle and upon further downward movement of the handle 21 the foot 18 is raised and caused to lift the axle therewith. l/Vhen the desired height is obtained the handle 21 is released and the elongated link 27 is caused to bind u on the rod 29, as the rod 29 is carried upwar ly through the medium of the binding link 13 in its upward sliding movement, permitting the link 27 to'slidably and loosely move over the sides of the rod 29 by reason of the weight of the handle 28 attached thereto, and prevent the downward movement of the rod 29 and thereby swing the forward end of the binding link 13 against the forward edge of the post 11 and cause the same to bind thereagainst, thus securing the foot 18 rigidly in position. The nut is now removed from the axle by means of the wrench 25 and is held upon the handle 21 which is ositioned substantially horizontally and t 1e nut is thereby prevented from vfalling in dust and other foreign substances incident to the throwing of the same upon the ground.

The bracket 30 is ada ted to support a grease pot from which t e o erator is enabled to remove grease to app y to the axle without the necessity of carrying kthe same se arate within his hand.

y en it is desired to release the foot 18 the handle 21. is slightly depressed when the elongated link 27 is permitted to be raised by the handle 28 and admit of the sliding of the rod 29 downwardly to disengage the binding link 13 from the post 1 1 and to thereby admit of the lowering of the lifting bar 15 by raising the handle 21.

Having thus described the invention what is claimed as new is 1. A device of the class described comprisinga base, a post upwardly extended from said base, a brace diagonally positioned between said post and said base for supporting said post, a binding link loosely disposed about said post, a lifting bar pivotally secured to the forward extremity of said binding link and extended upwardly therefrom, a handle pivotally mounted adjacent its forward extremity on said post near the upper end thereof, said handle pivotally connected to the upper extremity of said lifting bar, a rod upwardly extended from the rear end of said binding link, and a gravity clutch pivotally disposed upon the upper end of said post and loosely connected to said rod for the purpose of engaging the same upon the downl ward movement of said rod.
