.Application filed September 30, 1916. Serial No. 123,001.

To all w/wm may concern: it known that L ANDREW SADLOCK, a "u the United States, residing at in the `county of Fayette and lit venia, have invented cerain new at. u. il Improvements in Elevatingdaoks, or which the .following is a specification.

This invention relates to certain new and useful improvements in elevating jacks.

.lhe primary objectoif the device is the provision of lifting jack especially adapted for u'se with automobiles, the same being provided with adjustable axle-receiving members whereby the entire end oli a vehicle may be readily elevated as found desirable. A further object of theldevice is the `provision, of a lifting jack having an adjustable stop limiting means for the vertical movements got the vehicle supporting meniher, such member being freely revolnble and capable oflateral tilting, shiftable load-receiif'ing means being carried by the 4said member. 1

. it. still further object of the device is they provision. of a jacli that'is easy and inem 'pensi-ve to manufacture, the saine being capable of elevating a weighted body tilt-` a'bly and revolubly positioned, ineens being arranged llor supportingbodies of different dimensions. ,With these general obiects in view and others that will appear as the nature of the invention is better understood, the sama een sists in .the novel construction, combination and arrangement of partshereinafter more fully described,' illustrated in the aeeonipanying drawings, and then claimed.

In the drawings forming a part of this application and in which like designating characters refer lo 'corresponding parts throughout the severalviews r-Figure 1 is a front' elevation of the device partially broken away. Fig. 2 is va side elevation thereof. Fig. 3 is a top plan view of thel same. Fig. 4t is a longitudinal sectional View taken upon line IV-IV of Fig. 3'. through the supporting platform. Fig. 5 is a perspective view of the supporting platform detached, and Figs. 6 and 7 are perv spectire views of the two adjustable slides employed with the platform.

The .present device provides a standard 10 of inverted U-shaped arrangement having projecting feet l1 while three parallel lbraces 12 are arranged within the said standard connecting the sides thereo together. central perforations 13' in alinement with each other through which a threaded shaft lit is freely arranged. An operating sleeve 15 is screw-threaded upon the shaft 1-l between the top cross head 16 of the standard 10 andl the uppermost brace l2, a pinion..

17 being carried by the sleeve 15 in'constant mesh with a gear 1S upon a stub shaft '19 journaled in one side of the standard l0 and arranged with a turn crank .20. 1

A pivotv block 21 is swivelly connected with the upper end of the shaft 14 as at 22 while a work holder or supporting platform 23 is pivoted to the block 21 by a pintle 24e.

A main slide having longitudinal side flanges 26 is longitudinally slidably arranged upon the platform 23 with its flanges positioned beneath the inwardly projectingoverlying angular sides 27 of the said plat-` form. An auxiliary slide 28 is longitudinally shiitably arranged Within an under-- neatli groove29 olf the aforementioned slide 25,",Whereby both of the slides form a mounting 'lidjlistable in length upon the platforml 28,' as best illustrated in `Figs. 8 and 4 of the drawings. A set screw 30 extends' through a threaded opening Sl'in the main slide 25 being adapted for engaging the adjacent face of the auxiliary slide 28 which auxiliary slide is thereby frictionally `enkgaged with the platform 23, the slides being in this manner retained in their 'adjusted positions upon the platform 23.

Ltshaped supporting sockets 32 are provided 'with threaded Shanks 33 vertically adjustably positioned adjacent the opposite free ends of the said slides. j

It Will be understood from this descripL tion of the device that the-platform 23 is laterally pivoted as Well as rotarily mounted upon the shaft 11i, the latter being readily moved vertically by turning the crank 20. The socket members 32 are designed for receiving an elongated member. such as an automobile axle, being capable of adjustmentl for attachment to uneven portions thereof While the'longitudinal adjustability of the slides and 28 allows the socket members 32 to be readily adjusted with the Work positioned therein While the Set screw retainsthe slides so adjusted. The Work may then be tilted upon -thel pivot pintle -24 or lturne'd upon the swivel 'bonnection 22. A collar 84: is adjustably mounted upon-the The braces 12 are provided with 1. A jack comprising a standard, an o1 erating shaft carried by the said standard, a block swiveled in the upper `free end of the said shaft, a. 4latform ivfitally mounted upon the said lock havmg inturned sides adjacent 'the top thereof, a main slide mounted upon the top of the said platform having side flanges arranged beneath the said sides and having an underneath recess, an auxiliary slide positioned upon the top of the said platform slidably arranged within the said recess, and an adjustment retaining means for the said slides.

2. A jack comprising a standard, an operating shaft carried by the said standard, a block swiveled in the upper free end of the said shaft, a platform pivotally mounted upon the said block having inturned sides adjacent the top thereof, a main slide mounted upon the top of the said platform havin side flanges' arranged beneath' the said sldes and having an underneath recess, an auxiliary slide positioned upon the1 top of the said'platform slidably arranged within the said recess, an adjustment retaining means for the said slides, and U-shaped work receivers provided with threaded shanks adjustably arranged through the oppositiev free ends of the said slides.

In testimony whereof I ax mysignature.

ANDREW sADnooK.
