To-all whom z'tmay concern: "2 Be it known that L 'HnNRY AJ'WEINKE, a citizen of'the United 'states, residing at Sanbornfin the -county of GBrien and state 'of Iowa, have=invented anew and useful Lift King-Jack; and I do. hereby declare the following tobe a full, clear, and exact description of the' 'invention, such as will enable others skilled in the artto which it appertains to make and usethe'same. I

This invention relates to a tnew and useful lifting jack.

One of t'he objects of theinve'ntiion isthe provision of an improved device-of thisv nature having noyel, simple, desirable and practical features of construction;

The features of construction are herein-' after set forth,shown infthedrawings and claimed. j In the drawi'ngsr lii gure lis a view in side elevation'ashowing the improved lifting jack constructedin accordance with'the in; 1 vention. Fig. 2" is a-sectionalview. Fig. 3 -is are'ar view. {his a front view. Fig. 5-is a view taken partlyion'thesection'line 5'5 of Fig. 1,showing parts in elevation.

Referringto thd'drawmgs 1 designates the frame which comprises 'the vertical parallel bars 2, which rise f-rom the base 3, which is provided-with castenwheels 4. Connecting the side bars of the base is a plate 7 having an opening 8 in which the annular flange of the member 9 is seated. This member 9 constitutes a "race-way l0for the receptionof the ball bearings 11, which are engaged by the plate l2, whichds threaded upon a short shaft 12*. Secured between the plate12 and a nut 15- is a plate 12 having an annularflange provided with teeth 14. The nut 15 is threaded on the short shaft. An annular plate angular in cross section forms the raceway, 10. The flange of the plate :12 overhangs the member 9. Even though the plate 12 is secured between the plate 12 and the nut 15, the same' is threaded to the .short shaft 12". Connected to the short shaft by means of a pin 16 is a threaded screw rod 17, the upper end of which is mounted in a bearing 18, which in turn is swiveled inthe transverse bar 18*,by means of the screw 19. The. bearing-member 18 may be removed by loosening the screw 19. Between the hearing member 18 and the transverse bar 18 is .a washerv or plate '18". The'transverse bar 18 connects the upper ends of the vertical so as to'retatewith itis a gear 42 which carriagerQO *is provided, which comprises the frame 21, to 'WliiGh t-hQ angled arms '22 aresebured. at 23. These angle arms have secured toithem-a plate 24, upon which t'hecommodity-hn'the like rests, so as to be lifted. 'Secured'tmeach side of the-frame 21' are. ates 26',-which are constructed with ex- .ilBIlSlOIlS 27,-therebeing two upon each side ofweach vertical standard,whereby the carriaige' when naisedr may-'be guided. Mounted between :theextens'ions are anti frictional roller-s29, while the angular arms 22 are provided with similarrollers 29, Pivoted between thedoweropposite extensions is a all-shaped plate 30, through which the screw or' s'ha'ft passes, there being a crossv head 31 i secured tosaid plate by the bolts 32, and throughwhich cross head the screw :or shaft is" threaded. When thescrew or shaft is rotated in one direction orthe other, the carriage is raised or lowered.

Vertical bars 34 are connected betwee the upper ends of the vertical standards 2, and the base of the structure, and mounted "in 'theb'ars 34 is a shaft 35 having a crank handle '36 and a beveled-gear 37 wit-h which 'the beveled gear-38. meshes. The beveled gear '38is' carried by and rotatable'with the shaf-t39, which is mounted in bearings of the cross bars 40 and 41. The cross bar 40 connects betweenthe' bars 34, while the bar 41 is secured to the :base of the structure. I Mounted upon-the-l-ower end of the shaft 39,

meshes with the gear teeth 14 of the plate 12 When it is, desired to raise or lower' the carriage, the crank handle may be rotated Y in one direction or the other, thereby operating the shaft 35 and the gears between it and the shaft 39 and the gear 42. The gear 42 operates the plate having the teeth 14, and which plate when rotated imparts movement to the screw or shaft, and by reason of the fact that the screws 32 are threaded through the cross head, the saidcarriagewill be raised or lowered, the vertical .parallel standards 2 acting as guides. Thecarriage 20 may be removed for repairs, or for the purpose of installin a smaller-0r larger carriage having a sma ler or larger platform or plate 24. Another reason for removin the carriage, is to permit the same and t e other part of the apparatus to be easily packed for shipment. In order to remove thecarriage therollers parallel bars.

29 arefirst removed, and then the swiveled bearing member 18 guides pivoted-between the sides of the carriage,

said U-shaped plate having a cross head, a.

is detached by looseningthe' screw ,19, after which the pivoted screw section 17 or rod may be swung on its pivot, as shown in dotted lines in Fig. 2, so that access may be had to the pivot screws 30 of the pivoted plate 30, thereby permitting the carriage to be removed, then the pivoted U-shaped plate 30 may be screwed off the pivoted screw rod section 17, being that its upper end is free fromthe swiveled bearing member 18.

The invention hav ng been set forth, what is claimed as new and useful is 1. In combination, a frame having a base and provided with an upright portion consisting of two parallel beams constituting vertical guides, a carriage movable on-the and provided with 'a U-shapedplate threaded screw mounted in hearings in the upper and lower portion of said frame and extending through said U-shaped plate and threaded in saidcross head, and means geared to said screw for operating, the same.

- 2. In combination, a frame comprising a base, uprights forming guides rising from the base and provided with a cross bar at their upper ends,'a transverse bearing plate securedto the base, a ball bearing mounted gear carried by saidbearing plate, a screw pivoted'to said gear and swivelly-mounted at its upper end 1n said cross bar, a carriage mounted on said guides and having connections with said screw, and means hav ng gear connections with said ball bearing mounted gear for imparting revoluble motion thereto;

3. In combination, a frame comprising a base, uprights forming guides rising from the base and provided with a cross. bar at their upper ends, a transverse bearing plate j secured to the base, a ball bearing mounted gear carried by said bearing plate, a screw mounted on said .gether, one. the gear, while the pivot between the secpivoted to said gear and swivelly mounted at its upper end in said cross bar, a carriage ides, a U-shapedpla'te pivoted between t e sides, of the carriage and provided with across head, through which said screw is threaded, and means tions is ust, short above the gear, 'a bearing member having a socket in which the upper endof the other screw section engages,means for swivelly and detachably connecting the bearing member to the cross bar, a carriage mounted on said guides, a U-shaped plate pivoted between the sides of the carriage and provided with a cross ea'd through which one of said screw sections is threaded, the pivoting ofthe U-shaped plate between the sides of the carriage constituting means.

whereby one'of the screwsections may be "swung onits pivot when the swiveled bearing is detached, and means having gear connections with said ball bearing mounted gear for imparting a revoluble movement thereto i to operate the screw.

In testimony whereof I have signed my name to this specification in the presence of two SllbSCIlblIlg witnesses.
