COMBINATION LIFTING-JACK AND WIRE TRETCHER.

Specification of Letters Patent.

Patented July 19, 1910.

Application filed September 28. 1909. Serial No. 519.920.

To all whom it may concern:

Be it known that we, Bunny ll. Wm: MAN, *nsrnno H. Wuazuax, and Junsox (l. CLEMENT, citizens of the United States, 5 residing at Woodrnti. in the county of Phillips and State of Kansas. have invented certain new and useful Improvements in .Combination Lifting-Jacks and \Vire- Stretcher-s; and we do hereby declare the 0 following to be a full, clear, and exact description of the invention, such as will onable othersskilled in the art to which itappertains to make and use the same.

' Our invention relatesto new and useful 5 -im )rovements in combination lifting jacks an wire strctchers and our object is to provide means for raising diil'erent articles when desired and more especially the axles of a vehicle when it is desired to remove the wheel therefrom.

A further object is to provide means in connection with the lifting device, whereby the same may be used for tretching wires -or the like and a further ooject is to provide an extension for the lifting device whereby the same may be used for raising objects from a point adjacent the base of the liftin device.

Other 0 jects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1 is a side elevation of the combination lifting jack and wire stretcher. Fig. 2isa sectionalview as seen on line 22, Fig. 1. Fig. .5 is a perspective view of a slightly modified form of lifting jack, and, Fig. 4 is a. detail View partly in section of the upper portion of that 0 form of lifting jack shown in Fig. 3.

' Refei ring to the drawings in which similarreference numerals desi nate corres ondin parts throughout the several views, 1 in cates .a base which may be constructed in any referre. form,extending upwardly from w ich is a. tube 2, into which is introduceda shank 3, the upper end of said shank being adapte to be introduced below an object when said object is to be elevated.

Attached to the base 1 is a standard 5. which standard is formed by bending a piece of metal upon itself and securing the two sections thereof to the base; thereby (provided with a head .4, which is forming a slot-'6 the full length, the lower end of the standard having angular extensions '4', through which and the baw l are introduced bolts 8 and by means of which the standard is attached to the bane.

Fixed to the upper end of the tube '2 and extending into the slot (3 of the standard is a head 9. while pivotally attached to said head. is a rin; 10, through which the shank 3 extends. the'axis of the opening 11 through said ring being at an angle to the axis of the shank 3 and of greater diameter than said shank, whereby when the ring is resting in a horizontal position. the upper end of the opening will engagqthe shank. while the lower edge of the wall of the opening will engage the shanl; diametrically opposite the point of engagement as first described and at the lower cndof the opening. said ring exerting a binding action on said shank when the ring is resting in a horizontal position. said ring serving to hold the shank against casually descending when resting in a horizontal p sition.

livotally mounted in the slot 6 and ad jacent the, upper end of the standard is a lever ll". to the inner end of Wlli(fll l. pivotally attached a link 12, while to the upper end of the link is attached a ring [1- similar to the ring 10. the walls of the opcning H in said ring 13 being arranged similar'to the opening 11 in the ring 10. whereby the ends of the opening 14 will grip the surfaces of the shank'and move said shank upwzr'dly. when downward pressure is applied to the outer end of the lever.

In operating the device as a lifting jack. the head 4 is'positioned below an object and the shank raised until the head engages the object, the two rings, in view of the angle of the openings therctlu'ough. permitting the shank to freely move upwardly. As soon as the head is seated against an object, downward pressure is applied to the outer end of.

the lever 11, which would cause the ring '13, in view of the angle of the opening thercthrougln to engage the shank and move said shank upwardly; while the ring 10 will bind against the shank 3 as soon as pressure is released from the lever 11" and hold said shank against descending. The outer end of the lever is then thrown upwardly its full stroke, which will lower the ring 13 on the standard and obtain a new purchase thereon, so that when the lever is again lowered, the shank will be further elevated and this 0peration eon inned until the ohjeet is raised to the prop 1' height. \\'hen it is tlttll'ttl to lower tlu"-:.. ;1l( into. the tube. the lever 11 is thrownupwardly.t'o bri11g the wall of the opening it substantially parallel with the shank I and the ring i is siniilarljt' posi- T ing objects of various heights from the base (if the jaek.

tioned through the medium of a ram 1- sanl ram being pn'atallr attat-hed to the head i and in position to be swung into engagement with the lower fare of he ring i i I rmnhination with a base. a tube on said base and a standard eonnet-ted to said base: of a shank teleseoped in said tube. a head eonwhereby said rin; will be swung on its pivot and the wall of the openmg It brought substanttall t 1m ahnenn-nt with the shank 3 and when the ring.-- are so positioned. the

shank may in freely lllllfltl dou'nu'ardl hen the devn-e is t he used for stt'th'lting wire. or similar o ierts. :1 ehain or eable in; at an angle to the trend of the shank. an additional ring surrounding said shank and above the lirs j mentioned ring. a lever l i-attarl1etl to a taple lion the louereinl ol' the shank. said ehain being used for a11- t-horing llH' lit tin g devi e. while to the upper or t'losed end of the standard is secured a strett-hing ehain l and by anrhoring the lifting jat-k through the medium of the t-hain i and attaehing the t-hain l5 to a strand of win. or a set-li n of woven wire, said wire may be readily strett-hed b operating the lever 11".

In Figs. 5 and lwe have shown a slightly moditit-d form of lifting jat-k and have shown attat-hed thereto an "extension 15 the upper end of whit'h is provided with a hook t). the free end of which is adapted to enter a soeket :21 in the upper end of the shank 3. while the lower end of the extension is provided with a fork 2;. which rests againsttl1e tube '2 and holds the extension parallel with the tube. 'The objeet of providing the extension. is to enable the jaek to be used for raisin; objects from a point near the base of the jark. said extension having a toot pier-e 23 at its lower end. which is adapted to extend below and engage the object to he lifted. I11 this ronstrttetion. the head i is rovided with a laterally extending arm 2!. the outer end of which is extended upwardly and provided with a pin 15. with 'llltll engages the terminal 26 of a lot-king ring .27. the opening :28 in said ring beit1; eonstructed similar to the openings in the rings It) and 13. the terminal 26 being provided with an oblong slot 29, through whit-h the pin extends. By arranging the ring 27 in this manner, the shank will be seenrelv held in its elevated position and when it is desired to lower the shank. the ring is lifted through the medium of a finger piece 30. the provision of the slot 2!) permitting the ring to be swung upwardly. This form of deviee may also be used for stretehing wire. ete. by providing the ehain attat-lnne-nt as shown in Fig. 1, the operation of the two forms of jaek being the same.

By this construction. it will be seen that we have provided a very cheap and durable form of lifting jaek and one that'ean be readily t-onverted into a wire streteher and it will further be. seen that by using the extensions. the jut-k may be employed for lift What we t-laim is: 1. ln a lifting jat'li. and stretcher, the

nerting the upper end of the tube to said standard. a ring carried by said head. said ring having an opening through which the shank extends. the wall ,of said opening bepi\'ot:tll attat-hetl to said standard and a link t-onnet-ting said lever and the last referred to ring.

2. devit-e ot' the character described, eotnprising the t-omhination with a base. a tube and a standard rigidly seeured thereon; of a shank in said tube. bracing means between said tube and standard. ring members eneompassing said shank. one above the other and having openings therein disposed at an angle. one of said ring members being carried by pot-Hons of said bracing means. a lever pii'otally st'ittlttl to said standard and a link secured to the inner end of said lever, the opposite end of said link being pivotally seeured to said other ring member, whereby when said lever is pressed downwardly. said shank will be elevated and prevented from moving to its normal position.

3. In a deviee of the eharaeter described, the eombination of a base, a standard and a tube rigidly seeured to and extending up wardly from said base, a shank in said tube, braving means between said standard and tube. a pair of rings encompassing said shank, one above the other and having inclined openings therein. one of said rings being pivotally seenred to said bracing means, an operating lever fulcrnmed on said standard. a link seenred at its upper end to the other of said rings and at its lower end to said lever and means on said shank for engaging and raising an object.

In testimony whereof we have signed our names to this specification in the presence of two subseribing witnesses.
